2.WO/1991/011892ELECTRIC TUBULAR HEATING ELEMENT AND METHOD FOR MAKING THE SAME

WO - 08.08.1991

Clasificación Internacional F27D 99/00 Nº de solicitud PCT/SE1991/000045 Solicitante BACKER ELEKTRO-VÄRME AB Inventor/a ELOFSSON, Kjell-Åke

An electrically-operated tubular heating element comprises a metal sheath tube (1) filled with an e.g. pulverulent insulating material (2), and at least one helical resistance wire (3) embedded in the insulating material. The sheath tube (1) presents transverse corrugations (8) having a width (B) substantially exceeding the wall thickness of the sheath tube, the transverse corrugations haivng achieved the necessary compression of the pulverulent insulating material. In a method for making such an electrically-operated tubular heating element, the necessary compression of the pulverulent insulating material (2) is achieved by transversely corrugating the sheath tube (1), the corrugation width (B) substantially exceeding the wall thickness of the sheath tube.

4.WO/1991/005969A VALVE-ELEMENT SEALING ARRANGEMENT AND ITS USE IN A MIXER VALVE

WO - 02.05.1991

Clasificación Internacional F16J 15/32 Nº de solicitud PCT/SE1990/000677 Solicitante FM MATTSSON AB Inventor/a KRÅNG, Henry

A sealing arrangement for a valve element, such as a pressure control piston (31) in a mixer valve, includes an O-ring (34) which is accomodated in a groove (31b) whose axial length is greater than the diameter of the O-ring. The diameter of the O-ring is the same as or smaller than the depth of the groove, so that the O-ring will not have a braking effect on the free movement of the valve element. In the event of a pressure difference between the two sides of the O-ring, the O-ring is moved to one end of the groove, where the configuration of the groove bottom causes the O-ring to be urged against an outwardly lying element (3), while sealing the valve element in relation thereto.

5.WO/1990/011052APPARATUS FOR TRIGGERING SHOCK WAVES

WO - 04.10.1990

Clasificación Internacional A61B 17/00 Nº de solicitud PCT/SE1990/000182 Solicitante WIKSELL, Hans Inventor/a WIKSELL, Hans

Apparatus for triggering shock waves for therapeutic purposes, and generated with the aid of spark discharge in a liquid includes a signal analyzer disposed for receiving the ECG signal from a patient, a pulse generator being connected to this analyzer for sending a trigger signal shortly after the occurrence of the R peak in the ECG signal. An electromagnetically manoeuvreable, moving auxiliary electrode (14) is disposed for motion towards or into a fixed electrode gap (8, 10) in response to the trigger signal for connecting the spark gap (4, 6) to high voltage by making the electrode gap conductive.

6.WO/1990/011532MONITORING ELECTRIC CABLES

WO - 04.10.1990

Clasificación Internacional G01R 31/02 Nº de solicitud PCT/GB1990/000462 Solicitante RAYCHEM LIMITED Inventor/a BOTTOMLEY, John

A self-regulating heater cable (12) is monitored for detection of any damage thereto or discontinuity therein. The monitoring consists in comparing the value of the capacitive component of the earth leakage current following in the cable (12) between its live or neutral conductors (14, 16) and its earthed braid (10) at any one time with a predetermined value that itself is indicative of an intact cable. The value of the capacitive component of the earth leakage current is used to identify the location of any fault along the length of the cable (12).

7.WO/1991/008069DEVICE FOR CONTINUOUS CASTING

WO - 13.06.1991

Clasificación Internacional B22D 11/06 Nº de solicitud PCT/SE1990/000625 Solicitante JONASSON, Gunnar Inventor/a JONASSON, Gunnar

The invention relates to a device for continuously strip-casting metals, metal alloys or steel in which melt is tapped into a casting section for continuous casting defined laterally by four side walls. The invention is characterised in that opposite pairs of the walls consist of cooling strips movable across, with or against the casting direction, running at a speed greatly in excess of the casting speed, abutting the casting strand, or indirectly abutting the casting strand via individual fixed plates of carbon containing material such as graphite or the like.

8.WO/1992/001501FILTER APPARATUS

WO - 06.02.1992

Clasificación Internacional B01D 46/24 Nº de solicitud PCT/GB1991/001169 Solicitante BRIND ENVIRONMENTAL LIMITED Inventor/a GIBSON, Glenville

A circular filter cartridge for air pollution control has a plurality of pleats (10) so arranged on fold lines as to define an inner end wall (20) for each pleat on the periphery of a circle (22) of a first diameter, and outer walls (24) extending between adjacent pleats lying on the periphery of a further circle (26) of increased diameter. By providing flat surfaces, dust or other pollution does not build up at any particular point on the filter and also wear on the cartridge is reduced, leading to a more efficient and cost effective filter cartridge. Lower pressures of compressed air or liquid can also be used for cleaning.

9.WO/1990/013499METHOD AND APPARATUS FOR HANDLING STACKED PACKAGES

WO - 15.11.1990

Clasificación Internacional B65G 59/02 Nº de solicitud PCT/FI1990/000125 Solicitante ONNINEN OY Inventor/a LYSTILÄ, Juhani

The invention relates to a method for handling stacked packages (3) paricularly for distributive purposes. According to the method, pallets (2) of stacked packages (3) containing essentially one product are unloaded and arranged on to similar pallets (2) to form stacked packages (3) at least some of them containing different products. Unloading is done from warehouse tracks (4), each warehouse track (4) having packages containing essentially one product, on to at least one first transport track (6) in a stackwise manner and on to at least one second transport track (10) as single packages. The packages (3) are transferred via said transport tracks (6, 10) to a packing section where composite pallets are formed. Unloading at the end of each warehouse track (4) is accomplished by a gripping and transferring action performed on one or two adjacent vertical sides of one or two packages (3) in the stack for transferring on to at least the first transport track (6).

An abrasive compact comprising 40 to 90 volume percent of cubic boron nitride (CBN) crystals bonded by 60 to 10 volume percent of a bonding matrix comprised mainly of an intimate mixture of silicon nitride and metallic diboride MB₂ where M represents metal atoms chosen from the group of titanium, zirconium and hafnium atoms. The compact may be produced by a method which comprises intimately mixing particulate CBN crystals with a bonding agent in the proportion 95 to 60 volume percent of CBN and 5 to 40 volume percent of bonding agent, the bonding agent containing the metal atoms in the atomic proportions Si₃₀M₇₀ to Si₈₅M₁₅, subjecting the mixture of CBN crystals and bonding agent to temperatures in the range 900° to 1800 °C and pressures in the range 5 to 70 Kilobars, and maintaining the temperature and pressure conditions for a period of at least about 30 seconds, sufficient to cause most of bonding agent to form the bonding matrix.
