Title: Method and apparatus for the thermal treatment of foodstuffs
IPC: A23L3/26
Filed: 1979-08-06
Abstract: The distortion or bursting of air- tight packs containing foodstuffs including an evaporatable constituent such as water, during heating of the packs e.g. for sterilisation purposes, is reduced or eliminated by subjecting the pack to an electromagnetic high-frequency alternating field while the pack is surrounded on all sides by water which is pressurised to at least substantially compensate the internal pressure generated in the pack during the irradiation, the water pressure being subsequently lowered as the pressure within the pack falls as a result of the pack cooling.

Title: Safety electrical switch arrangement
IPC: G05G9/047
Filed: 1980-05-13
Abstract: An electric joystick control comprises a pair of switch contacts 18,20 for disabling the controlled equipment. In the neutral, undepressed condition of the joystick handle 10, an annular contact 20 on the handle stem 10 locates within an insulating gate 16 and the handle must be depressed against spring bias before it can be pivoted to execute controls, but if the depressing force is removed whilst the handle is pivoted out of its neutral position, then contact 20 will engage contact 18, which is formed on the lower side of gate 16. When the contacts 18,20 close, relays are operated to cause the controlled equipment to be disabled until the controls 18,20 are opened. If the contacts 18,20 become corroded resulting in an increased contact resistance, the controlled equipment is disabled until the contacts 18,20 have been cleaned. <IMAGE>

Patent GB-2076941-A (GB)
Title: Flow regulating valve
IPC: A61B5/0235
Filed: 1981-05-21
Abstract: A valve (1) for controlled ventilation of an inflatable sleeve of blood pressure measuring equipment comprises within a housing (3) a generally cylindrical rubber-elastic flow control body (7) with an axial bore (7a) forming part of a flow path (15) through the housing (3) from an inlet (3a) to an outlet (9). The body (7) is held at its ends and has on a circumferential surface portion thereof intermediate its ends an annular recess (7b) forming part of a pressure chamber (19). The chamber (19) is connected to the flow path (15) between inlet (3a) and bore (7a) by a branch duct (17). On ventilation of the sleeve, air under pressure is exhausted from the sleeve through inlet (3a) to the pressure chamber (19) and in dependence on the pressure difference between the inlet (3a) and outlet (9), the pressure in the chamber (19) deforms the control body (7) so as to constrict bore (7a). This varies the resistance to flow along the flow path (15) and causes the pressure in the sleeve to reduce, over a certain pressure range, at an approximately constant rate. <IMAGE>

Patent GB-2084900-A (GB)
Title: Thread lock
IPC: F16B33/06
Filed: 1981-09-28
Abstract: The method of making self-activating thread lock structures which comprises depositing a fluid material including an uncured fluid resin e.g. of microencapsulated material in the thread grooves of a threaded member; immediately thereafter, while the material is still in fluid condition, applying a thin fluid film- forming cover coat over the fluid material; and immediately thereafter transforming the cover coat into a thin, solid, dry, non-tacky, rupturable film by brief exposure to radiation, such as ultra-violet radiation. As previously noted excellent results have been obtained using ultra- violet lamps as the source of radiation to effect substantially immediate cure of the film-forming material, but other sources are comtemplated, such as electron beam radiation. Preferred film-formers are derived from acrylated urethane and glycidyl ether monomers, di- and tri- acrylate monomers, vinyl pyrrolidone, vinyl versatate and vinyl acetate.

Title: Printed circuit board connector
Inventor: ANHALT JOHN WILLIAM
IPC: H01R12/89
Filed: 1983-04-29
Abstract: A printed circuit board connector includes a thermoplastic body (14,15) having two extended generally parallel jaws (18,19), at least one of which contains a plurality of laterally spaced conductive leaf springs (20,21,22, 23) in an arrangement congruent with a corresponding plurality of circuit traces (12, 13) at the edge of a circuit board (11) to which it is desired to make electrical connections. A U- shaped metal return spring (24) biases the jaws towards each other, this spring bias serving to provide a compressive clamping force against the circuit board. A linear cam or plunger (25) slides within the U- shaped spring to prise it open for zero- insertion force connection to the circuit board, that is, with little or no sliding friction. Once in place, the linear cam or plunger is moved outwardly, permitting the U-shaped spring to bring the noses at the extremity of the jaws into a compressive grip against the circuit board. The elongated conductive strips within at least one of the jaws overtravel resiliently when jaw contact is made and thereby exert a contact force against the circuit board traces which is substantially independent of circuit board thickness variations. <IMAGE>
