Patent CH-675730-A5 (CH)
Inventor: GRESCH WALTER
IPC: C11B1/10
Filed: 1988-03-30
Abstract: In a process for recovering oil from natural products, the raw material is size-reduced in a processing installation (1) and treated by cellular disintegration. The oil released thereby is emulsified by the addition of water. The oil/water mixture is then separated from insoluble proteins and cellular material in a crossflow filtration device (5). The cellular disintegration and emulsion formation can also be carried out separately or in the crossflow filtration device (5). As a result of these measures, the quality of the end product is improved and the yield is increased at low operating costs.

Patent CH-607975-A5 (CH)
Title: Line of accumulating rollers
Inventor: GISIN FRANZ
IPC: B65G47/26
Filed: 1976-02-23
Abstract: The line of accumulating rollers has supporting rollers (1) which convey a piece goods item (2a) in the direction of the arrow (3) in such a way that it moves forwards when a piece goods item (2b) is removed, without human intervention, without contact and without accumulation pressure. Three supporting rollers (1) are combined by means of transmission elements (4) in each case, and each supporting roller (1) is connected to the drive element by means of a spring band coupling. This means that the use of frictional elements to transmit the driving torque can be avoided and a higher degree of safety can be achieved when operating in wet conditions. <IMAGE>

Title: Wave shed loom magnetic shuttle drive - with friction force between shuttle and shedding mechanism eliminated
IPC: D03D49/44
Filed: 1973-03-09
Abstract: At reat, the shuttle magnet assembly of magnets polarised perpendicularly to the direction of movement, alternately polarised, lie over, and are attracted to, the similarly arranged driver part, with a small air gap between. The driver perpendicularly orientated magnets are smaller and between them have magnets polarised in the motion direction, whose poles are, on the air gap side, arranged with like poles of the perpendicularly orientated magnets. When the driver moves, its poles are displaced to come towards like poles of the shuttle magnets, which repel, giving not only driving force but also separating force levitating the shuttle to eliminate friction.

Patent CH-624474-A5 (CH)
Title: Hot-water installation with a large number of hot-water accumulators
Inventor: KOLLE KJELL
IPC: F24D17/00
Filed: 1978-12-22
Abstract: A number of hot-water accumulators (1 to 4) connected to a common cold-water inlet line (5) are connected via shut-off or diverting valves to a common hot-water outlet line (6). Three-way valves (11 to 13), which either connect the respective accumulator to the hot-water outlet line (6) or open the passage to the preceding accumulator, serve as diverting valves. The valves (11 to 13) are controlled in particular depending on the charging state of the accumulators. The division of a hot-water accumulator arrangement into a number of smaller accumulators makes possible, in the event of a faulty accumulator, easier exchange of the latter. The proposed circuit arrangement guarantees optimum utilisation of the accumulators. <IMAGE>

Title: Pressure transducing reverser for use withbutane or propane
IPC: F16K31/524
Filed: 1969-08-19
Granted: 1971-05-14
Abstract: The supply gas e.g. butane or propane is supplied to the utilisation point via an open spring loaded valve situated on one side of an enclosed sprung membrane. As the gas bottle is exhausted the pressure relaxes on the membrane which operates an oblique cylinder acting on the supply valve to isolate the exhausted bottle and on a subsidiary valve on the opposite side of the cylinder to admit gas from a reserve bottle. The operation of the pressure reducer is rapid so that the interchanged gas supplies do not mix during the reversing operation.
