WO - 19.03.1992

Clasificación Internacional C07H 21/00 Nº de solicitud PCT/US1990/004994 Solicitante GEN-PROBE INCORPORATED Inventor/a BHATT, Ram, S.

A composition suitable for sulfurizing an organophosphite. The reagent comprises a solution of sulfur and a tertiary amine, in a suitable solvent such as carbon disulfide. The tertiary amine is preferably an optionally substituted trialkyl amine, for example triethylamine or diisopropylamine. A method is also provided in which phosphites or phosphonous esters are sulfurized to their corresponding phosphorothioates or phosphonothioates, respectively, using compositions of the present invention. This method has particular application to produce internucleotide phosphorothioate or phosphonothioate bonds in a nucleotide multimer.

2.WO/1982/002901STABLE HIGH COPY NUMBER PLASMIDS

WO - 02.09.1982

Clasificación Internacional C12N 15/69 Nº de solicitud PCT/US1982/000246 Solicitante CETUS CORPORATION Inventor/a GELFAND, David, Harow

DNA plasmids which are selected mutants in which an altered repressor gene leads to high copy number replication. Elements in the plasmids are modified by placing a suitable transcriptional 'stop' signal after an inserted heterogenous gene so that readthrough expression of heterologous DNA inserted in the plasmid will not continue into the replication primer strand. Deletions resulting from interference with replication primer strand transcription are thereby avoided.

3.WO/1990/009492AUTOFITTING BUILDING BLOCKS AND BRICKS

WO - 23.08.1990

Clasificación Internacional E04B 2/02 Nº de solicitud PCT/US1990/000797 Solicitante CAROTI, Gino Inventor/a CAROTI, Gino

An autofitting building block (1) has two opposing side surfaces (3), two opposing end surfaces (5), a top surface (7) and a bottom surface (9). The top surface has a plurality of dihedral projections (11) which mate with a plurality of dihedral recessions (13) on the bottom surface. The bottom surface may have at least one more recession (13) than does the top surface so that a channel is formed between two stacked bricks. Grooves (17) are preferably placed in the end walls which form vertical channels which communicate with the horizontal passages. A wall made of such bricks is also disclosed. The blocks can be either solid or hollow, and special blocks can be used for the corners and for the ends of the wall.

4.WO/1997/016761MAGNETIC EYEWEAR SYSTEM

WO - 09.05.1997

Clasificación Internacional G02C 9/00 Nº de solicitud PCT/IB1996/001273 Solicitante SUNREEVE CO., LTD. Inventor/a NISHIOKA, Takahiro

A dual lens eyewear system is disclosed having primary and auxiliary eyeglass frames that can be interconnected magnetically. The primary and auxiliary frames each have a pair of permanent magnets located at the peripheries of the frames, so that the auxiliary frame can be detachably connected to the primary frame by the attractive force of the magnets. The magnets are high-powered, so that the frames remain interconnected even when the wearer engages in light sports or other activities involving sudden movements of the head, yet the magnets are small enough to be barely visible to an observer. The auxiliary frame could contain any of a number of lens types, such as sunglass lenses, magnifying lenses, reading lenses, or decoratively colored lenses. The auxiliary frame is also foldable to allow for storage of the frame in a small space when the frame in not in use.

5.WO/1999/009298SEGMENT FOR INTAKE TUNNELS

WO - 25.02.1999

Clasificación Internacional E02B 11/00 Nº de solicitud PCT/JP1998/003504 Solicitante OBAYASHI CORPORATION Inventor/a MIYA, Kiyoshi

A segment (20) has four segment units (22) into which a cylinder of a prescribed length is divided in the circumferential direction. Each unit (22) is provided with a segment body (22a), a porous concrete layer (22b), an intake hole (22c), and a lid (22d). The segment body (22a) is made of a cast iron or steel plate, and its outer peripheral surface has concave parts recessed inward. The concrete layer (22b) is a water-permeable porous body filled in concave parts (201a) and solidified. A plurality of the intake holes (22c) are formed penetrating the flat bottoms of two concave parts (201a) at prescribed intervals in the circumferential direction. The lid body (22d) is detachably screwed and fixed to the intake hole (22c) to block the intake hole (22c) and, when removed, can open the intake hole (22c) to the outside.

6.WO/2002/047475METHOD OF EFFICIENTLY CONSTRUCTING TRANSGENIC BIRDS AND TRANSGENIC BIRDS THUS OBTAINED

G₀ transgenic chimeric birds having a target gene or gene sequence in germ cells at an extremely high efficiency and transmitting it to offspring and a method of constructing the same; and transgenic birds having a target gene or gene sequence in somatic cells and germ cells and a method of constructing the same. These G₀ transgenic chimeric birds carry a gene transferred thereinto by using a replicability-defective retrovirus vector and show a transmission ratio of the transferred gene to G₁ of 10% or higher.

7.WO/1999/041818TERMINAL STRUCTURE FOR CHARGING EQUIPMENT

WO - 19.08.1999

Clasificación Internacional H02J 7/00 Nº de solicitud PCT/JP1999/000625 Solicitante STAF CORPORATION Inventor/a YAMAMOTO, Masami

A terminal structure for charging equipment in which a charging output terminal is exposed, capable of being used safely even when a line transformer is omitted. The terminal structure comprises a frame member (l) fixed to a casing (9) for the charging equipment, a movable contact member (4) which is fitted and slidingly moved in a hole (2l) provided in the frame member (l), and which contacts a charging terminal of an apparatus (8) to be charged, a plate spring (5) fixed to the frame member (l), a spring member (6) electrically connected to a conductor (4l) of the movable contact member (4) via a coiled spring (2), and a lever member (3) adapted to be turned when the apparatus to be charged is placed on the casing, as the lever member is supported on the frame member (l), by a projection (8l) of the apparatus to be charged, to operate the plate spring (5) and engage the spring member (6), the movable contact (4) which contacts the charging terminal of the apparatus (8) to be charged being shut off from a power source circuit of the charging equipment unless the apparatus (8) to be charged is placed on the casing (9), whereby a line transformer is rendered unnecessary.

8.WO/1999/047803INTEGRATED RANKINE ENGINE

WO - 23.09.1999

Clasificación Internacional F01K 21/04 Nº de solicitud PCT/AU1999/000145 Solicitante GUTTERIDGE, Dennis Inventor/a GUTTERIDGE, Dennis

A Rankine or steam engine with integrated features is disclosed. The example is a four-stroke engine arranged such that hot gas enters the cylinder (7), is compressed (8), is mixed with a spray of water which turns to steam. The resulting pressure increase provides a power stroke (9), after which the expanded gaseous mixture is exhausted (10) to be condensed. The steam-generating phase of the Rankine cycle is thus integrated into the expansion phase for a simpler, more efficient engine.
