Title: Valve assembly for fire extinguisher - has spring loaded valve disc on plunger forced into gas cartridge
IPC: A62C13/74
Filed: 1976-01-08
Abstract: The gas bottle (5) its into a holder (6) attached to the extinguisher head (1). Above the bottle is a pin (15) on a plunger (14) fitting into a blind hold in an outer cap (16) which can slide in a bore (3) in the extinguisher head and is operated by the handle (18). On top of a shoulder on the plunger is a valve disc (21) urged against a seat (4) in the lower part of the bore by a spring (24).

Title: Typewriter with rollers pressing paper onto platen - and driven by platen to avoid paper slippage has roller peripheral speed matching platen speed
IPC: B41J11/00
Filed: 1976-01-28
Abstract: The typewriter has a platen (18) and it has rollers whereby the typing paper is pressed against the platen so that friction between the platen and the paper causes latter to be fed when the platen is rotated. To prevent slipping between sheets when several sheets are fed together, the rollers are geared to the platen to have the same peripheral speed. The gearing may be by an endless belt (4) trained over pulleys (9, 15) on spindles (3, 2) which are spaced around the platen periphery and to which the rollers are secured. One run of the belt engages the platen to be driven thereby and thus rotate the spindles and rollers.
Patent FR-2353121-A1 (FR)
Title: Cable with concave gap between soft insulation and metallic sheath - to accommodate bending or thermal expansion without splitting
Inventor: DEINESS SERGE
IPC: H01B13/00
Filed: 1976-05-26
Abstract: Electric cable comprising a metallic (copper) core conductor surrounded by insulation and a metallic sheath, where the insulation occupies most (90-99%) but not all of the volume between the core and the sheath and is shaped to contact the sheath at intervals around the insulation/sheath interface. The insulation is soft enough to be deformable, pref. or PTFE or polyethylene. Used for flexible cables where the insulated core is gripped by the external sheath, for high frequency (several GHz) signals. The free volumes between insulation and sheath allow to accommodate without bursting the greater thermal expansion of the insulation material if the cable is heated. The cable can be flexed more readily than if the insulation fills the sheath cavity.

Title: Heat transfer through heat-conductive wall - by projecting a liq. onto wall, esp. for boilers and heat exchangers e.g. in cheese making
Inventor: JUST MARCEL
IPC: A01J25/02
Filed: 1976-06-10
Abstract: Process transfers heat through a heat-conductive wall, by projecting liq. into the wall in multiple thin jets at a given temp.

Title: Electrophoresis appts. for fractionating materials on a gel - contains two buffer solns. electrically isolated in a container
Inventor: LEGAULT-DEMARE JEAN
IPC: G01N27/447
Filed: 1977-01-14
Abstract: The electrophoresis is carried out on a vertical gel whch is in contact with two buffer solutions, one of which is anodic and the other cathodic, the two being electrically isolated. The two buffer solutions are contained with one container, separated by a layer of a third liq. which is non-miscible, and non-reactive with the other two and acts as a liq. insulator. Various arrangements of the apparatus are possible but in each case a section of the container is separated from the rest in such a way that the lower buffer solution may rise up the separated section to reach virtually the same height as the top of the upper buffer solution thus allowing the electrode to be placed in the lower buffer solution without passing through the two solution above it and also making a route for gases produced to escape. Appts. may be used to fractionate proteins, nucleic acids and in general any substance which needs to be fractionated by electrophoresis of a gel. The appts. is simple and may be used with varying size plates. It can be used for the recovery of the fractionated substances by electrophoretic elution giving a good yield.

Title: IC engine cooling system - has pump driven by electric motor with control circuit receiving constant voltage input and variable input from temp. transducer
IPC: F01P7/04
Filed: 1977-03-16
Abstract: A pump (4) circulates cooling water through an internal combustion engine (1). The water coming from the engine is cooled in a radiator (2) by heat exchange with air which is blown over the radiator by a fan (8). A thermostatically controlled three way valve (5) between the pump and the radiator can bypass water round the radiator to prevent excessive cooling. The water pump (4) is driven by a variable speed electric motor (11). The motor is energised b a control circuit (13) which has a constant voltage input to serve as a reference base and a variable input from a temperature transducer (12) on the engine. The pump speed is thus governed to maintain optimum combustion temperature for efficiency and a clean exhaust.
