Title: Handgrip for car interior - with pressed supports for lateral stability fitted to screw in body
Inventor: LEHMANN ADOLF
IPC: B60N3/02
Filed: 1974-01-19
Abstract: The handgrip is reinforced by a metal strip insert which is flexible and which limits the stretching of the handgrip. The ends of the metal strip are secured on screws which are screwed int the car body. The metal grip is provided with tags and pressing near the screw fitting hole to locate the strip on cut-outs and tags on the body so that lateral forces are effectively absorbed. This stabilises the handgrip and prevents it twisting about the fitting screws, with subsequent loosening. The screw is further secured by metal springs tags.

Title: Rotary internal combustion engine - has two reciprocating pistons on eccentric shaft within main rotating piston
Inventor: WIWIE GUENTHER
IPC: F02B57/00
Filed: 1974-08-20
Abstract: The engine has a circular cylindrical casing (1) within which is a concentric rotating piston (2). This has a central bore inside which are two reciprocating pistons (3) joined by connecting rods (6) to a crankshaft (5) running through the centre of the rotating piston. As the rotating piston turns the internal pistons are caused to reciprocate and suck the charge in through an inlet port (E) in the casing and compress it before it is ignited by the sparking plug. The expansion following combustion exerts a force within the main piston which causes the latter to rotate. The engine is vibration free, needs no oil pump and produces a large output from a small working volume.

Title: Fulling roller hydraulic coupling - has steel cylinder for each drive shaft with internal piston to operate brake/coupling action
Inventor: GOEBEL ERHARD
IPC: F16D67/04
Filed: 1974-10-05
Abstract: A hydraulic coupling is claimed, particularly for a fulling machine with the rollers operating in an intermittent motion, with a steel body for each individual drive shaft for a ring brake on the machine wall to surround and grip sections of the body.

Title: Engine crankcase gases treatment - by catalytic reactor in heat exchange and partial mixture with exhaust gases
Inventor: PALMA TED VERNON DE
IPC: F01M13/04
Filed: 1974-11-07
Abstract: A part of the crankcase gases of an IC engine which are recirculated to the fuel inlet system is passed through a heat exchanger with an oxidation catalyst where it is heated by hot exhaust gases. The catalyst effects an oxidation of the combustible components of the crankcase gases and the resulting gases, containing CO2 and water vapour, are introduced in the fuel inlet system. This prevents the deposits formed in the fuel suction, combustion chamber and spark plugs when conventional crankcase gas ventilation is applied. The recirculation of exhaust gases reduces the emission of N oxides. The system reduces atmos. pollution considerably.

Title: Stereophonic headphones for realistic reproduction - have acoustically coupled canals driven by twin loudspeaker diaphragms
Inventor: LEPPER WILHELM DR ING
IPC: H04R1/10
Filed: 1975-02-04
Abstract: The headphone set consists of a lightweight U-shaped tube with flared ends, which has openings or recesses on the inner circumference with pads for the listener's ears. The device is worn with the yoke in a horizontal position from the temples to the back of the head. The two front ends of the acoustically dampened tube are fitted with left-and right-hand channel loudspeakers. At the junction of the left- and right-hand, chambers is a butterfly valve for adjustment for optimum acoustic performance. By causing the sound wave front to travel parallel to the listener's ears, a far more realistic reproduction is achieved. This is particularly so if the original sound is picked up suing a "dummy head" microphone arrangement.

Title: Cutting depth control for face grinding machine - rotary and sliding movement of control spindle gives coarse and fine control
Inventor: BUERKLE HEINZ
IPC: B24B47/22
