Patent DE-2540367-A1 (DE)
Title: Aircraft with reciprocating wings - with interlocked pairs of wings with energy transfer between thm and human pedal power drive
Inventor: HAENLE FRED
IPC: B64C33/00
Filed: 1975-09-10
Abstract: The light aircraft has at least two sets of wings (2, 3, 22, 23) which are flapped up and down by a linkage to the driving force. The pairs of wings are interlocked by cable drives in such a way that when one pair is on the upstroke the other is on the downstroke. The stored energy of the wings on the upstroke is then used for the power stroke of the other pair. The system improves the efficiency of the drive mechanism, especially for man powered flight. It enables stored energy to be abstracted from air turbulence.

Title: Safety valve closure upstream of burst duct - has spring-loaded closure plug actuated by change in flow dynamics
Inventor: HELM HORST
IPC: F16K17/30
Filed: 1975-10-23
Abstract: A safety valve which closes when a sudden pressure drop occurs is intended for closing an outlet from a vessel when a sudden loss of press. takes place on the downstream side. The valve comprises a two-part, torpedo-shaped object coaxially mounted in the valve housing. The inner form of the housing tapers towards both ends so that the annular cross-section offered to the fluid throughout the housing length is substantially constant. The torpedo is composed of two separate cones, one of which is fixed (e.g. by radial ribs in the housing, while the other is movable and is held close to the fixed cone by a releasable coupling, esp. a ball coupling, but is biased away from it by a compressed spring. There is preferably an internal sleeve fixed inside the fixed cone to act both as the sliding bearing for the rod and as the cage for the ball coupling. A seal, esp. a spring bellows, seals the rod to the sleeve and fixed cone Esp. useful in a steam duct leading from the stream generator of a nuclear reactor, to close the passage if a burst occurs on the downstream side. No sensing measuring or similar devices are necessary; the valve is simple in action and extremely reliable. The torpedo shape prevents direct radiation shine along the valve.

Title: Combined harvester and chopper for beet - has transverse, elastically slatted pickup reel, collector trough, fan and conveyor belt
Inventor: WESTER HEINRICH
IPC: A01D33/06
Filed: 1975-11-05
Abstract: The harvester chassis has two sides (1, 2) and a pref. slatted back (3) which extends downwards and under to form a collector trough. A pick-up reel (5) with elastic, e.g. rubber, bars is mounted in the chassis and driven by a gear-mechanism (7) from a drive shaft (8). Inside the collector-trough is a transverse conveyor-screw (9) which extends beyond the side (2) into a part (4') of the trough leading to a fan (10), from where the chopped crop passes through a tubular outlet funnel to a trailer. The pick-up reel (5) works in conjunction with a pref. slatted belt, the top stringer of which extends at a tangent from the lowest point of the reel to the top edge of the collector- trough.
Patent DE-2550910-A1 (DE)
Title: Forklift truck safety equipment - has relay preventing further lifting for set time after alarm functions
Inventor: WIKMAN LEIF ERIK
IPC: B66F17/00
Filed: 1975-11-13
Abstract: The equipment is particularly for high-lift trucks, equipped with means for interrupting the lifting movement so as to limit the load or the tipping moment. When lifting has been interrupted for this reason, a relay prevents re-operation of the lifting control for a set time interval, or until the control lever is returned to the neutral position. This relay can be incorporated in the lifting drive control circuit. The design prevents repeated switching on and off of the lifting motor caused by mast oscillation when handling nearly the maximum safe load at considerable height, and which might otherwise ultimately cause the truck to tip over.

Title: Moving-coil loudspeaker with nonmagnetic heat-sink blocks - above and below pole pieces to remove heat generated by coil
Inventor: WALL PETER KENNETH
IPC: H04R9/00
Filed: 1976-02-12
Abstract: The moving-coil loudspeaker has its coil (6) vibrating axially in the air gap between pole pieces. Non-magnetic blocks (9, 10) are located above and below the outer pole pieces (3) to remove the heat generated in the coil when the loudspeaker is in use. These heat-sink blocks have approx. the sme thickness as the pole pieces themselves. The centre pole likewise has a heat-sink block (11). The blocks and poles are chosen so that the total length of the air-gap between them is at least equal to the length of the coil, and preferably greater. This increases heat transfer between coil and heat-sink blocks.
Patent DE-2610585-A1 (DE)
Title: Load sensitive antiblocking brake control - has mixed select high or select low modes and load monitoring
Inventor: LINDER ERNST DIPL ING
IPC: B60T8/1764
Filed: 1976-03-13
Abstract: The anti-skid brakes can be operated on each axle in either select high or select low mode depending on the dynamic conditions. The loading of each axle is monitored and the select high mode is applied to the axle with the heaviest loading, while the other axle is set in select low. The control ensures that both axles have different braking modes to ensure a stable braking sequence. If any axle is switched in its braking mode then the other axle is switched in the opposite way. The axle loading is monitored by a simple pressure switch to provide a threshold level above which the mixed mode control operates.

The electrode, and the piston in the cylinder must have a position accurate to plus-or-minus 0.01 mm. The chambers on each side of the piston are prevented from being exposed to an unwanted charge of fluid pressure.
