1.WO/1997/013105METHOD OF LOW-TEMPERATURE STRATIFIED CHILLED WATER STORAGE

WO - 10.04.1997

Clasificación Internacional C09K 5/06 Nº de solicitud PCT/US1995/014656 Solicitante TRIGEN ENERGY CORP. Inventor/a MORNHED, Goran

The lower-most temperature of the thermal mass in a chilled water stratified storage tank (20) is lowered without reducing its density by the addition of sodium nitrite and sodium nitrate, alone or in combination, preserving thermal stratification so that both warm and chilled water may be stored in the tank, a benefit not previously obtained without the use of chemicals damaging to the environment. A solution of sodium nitrite and sodium nitrate lowers the freezing point of the cooling water to -13.2 degrees C (8.3 degrees F) yet still permits the chilled water to stratify in the storage tank.

2.WO/2000/072717FLUIDTIGHT ZIP FASTENER

WO - 07.12.2000

Clasificación Internacional A44B 19/32 Nº de solicitud PCT/EP2000/004785 Solicitante YKK CORPORATION Inventor/a NEUGEBAUER, Horst, Gotthard

The fluidtight zip fastener comprises a pair of fluidtight zip fastener carrying tapes (2, 3) carrying the zip fastener coupling member rows (4, 5) and which are in each case formed by a base tape (6) with a soft, synthetic rubber or similar covering layer (7). They engage on one another by their borders. A pair of continuous coupling member rows (4, 5) is sewn to the zip fastener carrying tapes (2, 3) in a spaced offset position transversely to the longitudinal edges of said carrying tapes in such a way that the facing borders (9) of the soft covering layers (7) are in contact with one another along a longitudinal plane, which intersects the zip fastener at a central axis thereof and runs at right angles to the zip fastener principal plane. The facing borders (9) of the zip fastener carrying tapes project over said longitudinal plane, when the coupling member rows (4, 5) are disengaged and namely to such an extent that said borders (9), when the coupling member rows (4, 5) are engaged, are bent away from the side carrying the coupling member rows (4, 5). They diverge in such a way that they extend roughly at right angles to the zip fastener principal plane. The soft covering layers (7) of the facing borders (9) of the two zip fastener carrying tapes (2, 3) engage on one another under pressure action and thus ensure the fluidtightness condition.

3.WO/2001/011848CARRIER FOR A MOBILE PHONE

4.WO/1997/008844METHOD AND APPARATUS IN A RADIO COMMUNICATION SYSTEM FOR MITIGATING NOISE AND INTERFERENCE EFFECTS

WO - 06.03.1997

Clasificación Internacional H03G 3/00 Nº de solicitud PCT/US1996/010762 Solicitante MOTOROLA INC. Inventor/a LI, Xiaojun

A method and apparatus for mitigating effects of multipath fading, interference, and noise in a single sideband (SSB) signal transmitted by a radio communication system and demodulated by a portable subscriber unit (122) utilizing a demodulator (304) compensated by a pilot signal power (406). The apparatus performs the mitigation process by calculating (708) a pilot fading threshold in addition to a muting threshold. When samples of the mean pilot signal power fall below the fading threshold, the compensation of the demodulated signal is adjusted (714). In addition, when the mean analog message signal power falls below the muting threshold, the samples included in the predetermined portion of the message are muted (718).

5.WO/1998/031884IMPROVED BUILDING STRUCTURES

The present invention resides in a modular building structure having a framework comprising steel wall members (5) having tubular studs (8) welded between upper (6) and lower (7) right angle members, steel roof trusses (11) formed of tubular members (13) welded between right angle members (12) so as to form shallow inverted V-shaped structures provided at their outer ends with bracket members (21) adapted to be fixed to members extending along and secured to the upper right angle members (6) of two opposed side wall members (5), and two flat roofing sections (20) of sheet steel adapted to be secured to the upper angle members (12) of the roof trusses (11).

6.WO/1996/020877COLLAPSIBLE SCOOP FOR DISPENSING VOLUMES OF FLUENT MATERIALS

WO - 11.07.1996

Clasificación Internacional G01F 19/00 Nº de solicitud PCT/US1995/016251 Solicitante THE PROCTER & GAMBLE COMPANY Inventor/a DUQUET, Jacky, Pierre

A scooping and dosing device is provided which comprises a first receptacle (top of the fig.) which is resiliently and stably collapsible. When collapsed, the first receptacle (top of the fig.) defines a second receptacle (middle of the fig.) of smaller volume which may be in turn resiliently and stably collapsible to form a third receptacle (bottom of the fig.) of smaller volume than the second receptacle.

7.WO/1999/040019CONTAINER CRANE

WO - 12.08.1999

Clasificación Internacional B66C 19/00 Nº de solicitud PCT/JP1998/000502 Solicitante HITACHI, LTD. Inventor/a NAKAJIMA, Ichirou

To make a container crane lightweight and shorten a cargo handling time. A central relay trolley (60) among three trolleys travelling on girders (31, 32) is provided with a cradle (61), on which containers from respective hoisting accessories (42, 46) on trolleys (41, 45) on both sides are placed. The trolley (60) suspends the cradle (61) with a length of rope (62). Landing is performed by suspending a container by means of the trolley (45) and placing the same on the cradle (61). The container on the cradle (61) is lifted by the trolley (41) and lowered on a land side. A level of the cradle (61) is based on a minimum level where the trolley (45) can travel with the container suspended. As cargo unloading proceeds, a level of the cradle (61) gradually lowers. When loading is performed, the level of the cradle (61) gradually rises. An auxiliary girder (37), on which the trolley (60) travels, is disposed on a land side of a junction of a tension bar (28) and the girder (32).

8.WO/1997/048768PAVEMENT BINDER AND METHOD OF MAKING SAME

WO - 24.12.1997

Clasificación Internacional C08L 95/00 Nº de solicitud PCT/US1997/002873 Solicitante EXXON RESEARCH AND ENGINEERING COMPANY Inventor/a PUZIC, Olga

The present invention provides a method of making storage-stable road paving binders by blending a minor amount of an unsaturated polymer (e.g., having at least one diene monomer) with a major amount of asphalt at an elevated temperature such that the components are sufficiently fluid to blend; treating the asphalt-polymer blend with a sulfonating agent; and stripping the treated asphalt-polymer blend at an elevated temperature with sufficient stripping gas to removed strippable sulfur moieties and to stabilize the resulting stripped, treated blend. The invention also provides asphaltic compositions made by the method. The asphaltic compositions are useful as binders in road paving applications.

10.WO/1997/005052SUSPENDER SWINGING METHOD AND APPARATUS THEREFOR

WO - 13.02.1997

Clasificación Internacional B66C 3/12 Nº de solicitud PCT/JP1995/001506 Solicitante HITACHI, LTD. Inventor/a HIRATA, Mituo

This invention aims at obtaining a large swing angle by a comparatively small apparatus. In an unloader having a grab bucket (55), four sheaves in a trolley (53) for suspending the grab bucket (55) are provided movably on a 45° inclined surface. The four sheaves are divided into two groups. Each group comprises lift sheaves and opening and closing sheaves. One group is positoned at a lower end portion of the inclined surface, and the other group at an upper end portion thereof. The wires extending from the two groups of sheaves and connected to a suspension point is inclined at 45° with respect to the axes of the sheaves. The sheaves for opening and closing the grab bucket are inclined at 45° with respect to the axes of the sheaves of the trolley. One group of sheaves in the trolley (53) are moved upward, while the other group of sheaves therein are moved downward. Consequently, the grab bucket (55) is swung through substantially 90°.
