Title: Compact sailing boat with multiple hull - has retracting mast and raising keel enabling deck line to be lowered
Inventor: HOHMANN HERBERT
IPC: B63B35/73
Filed: 1977-03-01
Abstract: The compact multi-hulled sailing boat has a retracting keel in the centre hull and has the hulls joined above the waterline to form a wide cabin space. The mast retracts so that the sail area can be trimmed to conditions without affecting stability. The separate cabins are reached by a passageway (13) along one side of the design, with the floor level in the passage lower than the floor in the cabins in the middle hull. This enables the deck line in the outer hulls to be lowered.

Title: Quick release shaft coupling - has telescopic parts with conical pressure surfaces connectable by screw operated radial bolts
Inventor: ARMASOW WALDEMAR DIPL ING
IPC: F16D1/05
Filed: 1977-05-10

The collars are connectable by screw-operated radial bolts. The bolts are movable in the direction of their length and each have a conical surface engageable with radially aligned conical holes of the two collars. The conical surfaces are convergent toward the axis of the coupling and the inner collar has slots allowing axial disengagement of latter collar from the bolts.
Patent DE-2723894-A1 (DE)
Title: High speed centrifuge safety switch - has ball catch blocking switch operation when lid is not completely closed
Inventor: LUTZ WALTER
IPC: B04B7/06
Filed: 1977-05-26
Abstract: The safety switch for a high speed centrifuge, prevents accidental starting as long as the lid is not closed completely. The bottom part (10) and top part (12) interlock and carry a lid. The lid has on its extreme edge a small recess into which the tip of a spring loaded catch pivoting on part of the top engages. When the lid is completely pressed down, the catch snaps into the recess and prevents its opening unless a push button forming an integral part of the catch arm is pressed. The electric motor driving the centrifuge is started by a switch (24) with a sliding button on the front of the top part (12) adjacent to the lid release button. The body of the switch has on its top a blind hole in which a spring-loaded steel ball (26) operates in two resting positions (12r, 12rr) in the inside surface of the top part. This surface has a further recess (12s) into which the top of a safety catch (28) rests due to the pressure of a spring (30) when the lid is not closed. This position of the catch prevents sliding movement of the switch as long as protrusion (18v) on the lid does not push the catch out of the recess (12s).
Patent DE-2730910-A1 (DE)
Title: Rotating cylinder block IC engine - has axial cylinders in ring fitted in block with cam action between piston rods and stator
IPC: F02B75/26
Filed: 1977-07-08
Abstract: The engine has a shaft carrying a rotor which has several axial cylinders (18) arranged in a ring round the shaft. A piston (9) reciprocates in each cylinder. The piston rod (7) carries a sphere (12) at the end opposite the piston and all the spheres run in a common undulating channel (13) which forms an annular ring on the stator. This converts the reciprocation of the pistons into rotation of the entire rotor. Admission of gases to the cylinders and exhaust from them is controlled by a valve plate (21) round the top of the cylinders which has appropriate ports in it. Combustion takes place in the working cylinders. The exhaust gases pass through a turbine (33) which drives a compressor for the inlet air.

Title: Sorting system for vegetables and fruit - has single width conveyor channel passing items in succession past monitor before being laterally displaced
Inventor: NONHEBEL PIETER
IPC: B65G33/06
Filed: 1977-07-29
Abstract: The fruit, vegetables etc. which are to be sorted and graded are passed in succession through a conveyor channel past a monitor operator or mechanism where spoilt items are then pressed sideways out of the channel where they are taken up by collector units. The conveyor channel can be formed by the surfaces of two rotatable rollers (2, 3) mounted side by side and rotate in the same direction at adjustable speeds. The spacing between the rollers can be adjusted so that different types of items can be accommodates. The roller surfaces are pref. roughened, e.g. provided with longitudinal ribs (4, 5) which helps to increase the rolling action and ensure that the items to be monitored are turned completely round.

Title: Vacuum cleaner fan mounting - uses hooped retaining brackets mounted in annular space surrounding relatively small motor adjacent to fan
Inventor: HOFFMANN RUDI
IPC: A47L9/22
Filed: 1977-08-03
Abstract: The motorised fan 3 of the vacuum cleaner is held by its end face containing the suction opening against a fixed wall of the surrounding chamber by a hooped bracket (10) in the space formed by the motor (4) having a smaller dia. than the fan (3). The bracket is braced on one side against the end face (5) of the fan facing the motor or against the motor itself and on the other side against an adjoining chamber wall (8). The chamber need therefore only be the size of the actual dia. of the fan so that a material savings is achieved.

Patent DE-2743274-A1 (DE)
Inventor: PAAR ADALBERT
IPC: E05B47/00
Filed: 1977-09-27
Abstract: The lock having a cylinder housing (10) and a cylinder core (7) is actuated by a magnetic key. The cylinder core (7) contains magnetic rotors controlling blocking pieces (1). Provided between the cylinder housing (10) and the cylinder core (7) is a preferably multi-part basket which is movable relative to these and which engages into the blocking pieces (1). In the rotary position (equals open position) of the magnetic rotors, the blocking pieces come out of engagement with the basket during the rotation of the cylinder core, and the cylinder core (7) can be rotated freely. In the blocking position of the magnetic rotors, the blocking pieces (1) and the basket remain in engagement with one another, and the force exerted in order to rotate the cylinder core is absorbed by the blocking pieces (1) which butt against a face of the cylinder housing (10). <IMAGE>

Title: Paper sack with filling valve - stiffened by aluminium foil coated with tissue paper bonded by polyethylene adhesive
Inventor: GROENER ALOIS
IPC: B65D30/24
Filed: 1979-01-17
Abstract: The material layers for the valve section of a sack formed from paper or other readily foldably material, consist of a weak aluminium foil, on one or both surfaces of which a layer of tissue or fine crepe paper is fixed by a layer of a synthetic adhesive based on low density polyethylene.
