Title: Double-acting piston pump, especially for fuels of internal-combustion engines
Inventor: ECKERT KONRAD DIPL ING DR
IPC: F04B9/06
Filed: 1981-09-04
Abstract: The downstroke (49) of the piston (15) is effected by a plunger (10) against the force of a restoring spring (22), and the upstroke (50) is effected by the storage capacity of a restoring spring (22). A brake spring (drag spring) (21) is arranged between the piston (15) and the plunger (10) so as to have the same effective direction as the restoring spring (22). Thus the brake spring (21) acts, during the upstroke (49), as a stiff element until the maximum pump pressure is reached, but when this is reached and the piston (15) stalls at the same time, the brake spring (21) stores the downstroke. One section (14) of the plunger (10) is arranged between the piston (15) and the restoring spring (22) in a non-positive manner, the storage capacity of at least one of the two springs bringing about the upstroke (50) of the piston (15). <IMAGE>

Title: Device for a fuse of a spin projectile
Inventor: KAISER HANS
IPC: F42C15/196
Filed: 1982-02-13
Abstract: Where small-calibre spin ammunition is concerned, it is necessary to ensure that a ball rotor (1) is fixed in the armed position when it has assumed the armed position for the first time. In addition, however, it is also necessary to ensure that the safety systems (22, 25-32) eliminate brief transport shocks. For this purpose, the ball rotor (1) carries balls (12, 13) in respective circumferential recesses (10, 11), the ball (13) already determining the centre of rotation for the rotor (1). For this, the ball (13) engages simultaneously into an annular groove (15) of the housing and into the rotor recess (10). A sliding-block safety device (25-32) acts, in addition to a known centrifugal-band safety device (22), as a mechanical filter against transport shocks. In the safe position, a sliding block (25) dependent on translational movement engages into the rotor (1) and fixes it. The sliding block (25) is mounted displaceably in a bore (28) arranged parallel to the longitudinal axis of the fuse. The aforesaid sliding block (25) is itself safeguarded by a further rotation-dependent sliding block (26) and a spring (27). The aforesaid sliding block is mounted displaceably in a bore (29) which is at right angles to the longitudinal axis of the fuse. <IMAGE>

Title: Temperature regulating device for air-conditioning installations
Inventor: THOMANN URS
IPC: F24F3/056
Filed: 1982-03-05
Abstract: An air-regulating flap (3) is arranged between a volume regulator (2) and an air heater (4). The air-regulating flap (3) is bypassed by a bypass pipe (10) which serves as a heat exchanger and to this end has a large external surface and a large internal surface. The bypass pipe (10) is laid in a ceiling cavity (11), via which air drawn off from a room to be air-conditioned is conducted. The fresh air absorbs heat from the outgoing air via the bypass pipe (10). By corresponding adjustment of the air-regulating flap, all the fresh air or a more or less great proportion of the fresh air can be guided via the bypass pipe (10). By means of such a device, a part of the outgoing-air heat is recovered and energy is thus saved. <IMAGE>

Patent DE-3228694-A1 (DE)
Title: Hydraulic shock absorber
Inventor: SCHMIDT RUDOLF
IPC: F16F9/512
Filed: 1982-07-31
Abstract: The intention is to provide a hydraulic shock absorber in which there is the possibility of integrating the shock absorber into the compressed-air system of a vehicle with pneumatic suspension, so that additional loading results in an automatic increase in the pressure acting on the rebound stage of the shock absorber. There should be temperature-controlled influencing of the damping force, irrespective of the air pressure. To solve this problem, the valve plate is arranged on that side of the restriction member which faces the piston rod. The valve plate interacts with an axially displaceable valve piston which forms one end wall of the chamber, and the effective cross-section of the valve plate during damping in the rebound stage can be altered via the valve piston acted upon by pressure. It is advantageous here that a temperature control system can be used independently of a compressed air control system.

Title: Process and apparatus for classifying solids of different density by means of a liquid separating medium in a cyclone
Inventor: FARAHMAND AKBAR DR
IPC: B03B11/00
Filed: 1983-06-24
Abstract: In the known cyclones for classifying solids of different density into at least two fractions by means of a liquid separating medium, the feed of the solids to be classified together with the liquid separating medium takes place through a tangential inlet. This common feed has the disadvantage that it causes extensive wear both in the inlet of the cyclone and on the pump. This disadvantage is avoided according to the invention in that the liquid separating medium is fed into the cyclone tangentially under pressure, independently of the feed of the solids to be classified, and the solids to be classified are fed into the cyclone axially. <IMAGE>
