Title: Rotary piston combustion engine - has separate combustion compression and output rotors arranged in parallel for improved combustion
Inventor: STOOKEY BYRON O
IPC: F02B53/04
Filed: 1975-06-28
Abstract: The compressor cylinder (13) and the working cylinder are arranged eccentric in relation to the drive shaft (10) with the combustion chamber (23) concentric to the shaft (10). The respective cylinders are each provided with a rotor (15, 25, 30) splined to the shaft which extends through both ends of the engine casing.

Title: Positionally constraining web support - has edge guide with spaced web presenting no resistance to movement
Inventor: SWANKE THADDEUS
IPC: G03G15/00
Filed: 1975-09-10
Abstract: A web support is mounted on a fixed frame for rotation in engagement with a moving web. The web support comprises an edge guide mounted in a predetermined location in the path of movement and having opposed web engaging portions a fixed max distance apart which corresponds to the width of the moving web, for establishing at the edge guide a fixed lateral spatial position of the web relative to the frame. A web support surface at the predetermined location rotates to track with the moving web, and present negligible resistance to changes in the lateral angular position of the entering web portion. The web support laterally constrains the entering web portion against change in its spatial position while permitting freedom of the entering web portion to change its angular position.

Title: Railway train coach concertina link - has flat finish cover over folds to exclude wind at high speeds
Inventor: HUEBNER REINHARD
IPC: B61D17/22
Filed: 1975-12-11
Abstract: The protection is for the crossover link between coaches in an articulated or coupled train, where passengers pass over a link bridge encompassed by a tunnel-type folding concertina sheath. Air resistance is reduced so that the link does not give rise to excessive noise on ultra-high-speed trains, resulting from eddying. The folds in the concertina link (1) are covered, giving it a virtually flat exterior surface. Each clamp element (3), on a link unit assembled from separate parts, may have an elastic shaped-section piece (5), held on it, with all these pieces combining to form flat walling which covers adjacent clamp elements.

Title: Hydraulic tappet clearance adjuster for overhead camshaft - has spring loaded non-return valve releasing fluid to atmosphere
Inventor: KRIEG JOHN JOSEPH
IPC: F01L1/24
Filed: 1976-02-18
Abstract: An adjuster cylinder (41) fitted in the top of the engine cylinder head contains a hollow piston (42) the end (43b) of which presses on the back end of the rocker arm. Oil enters the cylinder from the engine lubricating system through a hole (55) and finds its way into the hollow centre of the piston through a transverse passage (63) in the piston which it reaches past two annular grooves (59, 60) in the outside of the piston with a metering lip (61) between them. It escapes through the base of the piston past a spring loaded non return valve (48) into the bottom of the cylinder where it exerts an upward force on the piston to keep it in contact with the back of the rocker arm.

Title: Detector for ultrasonic burglar alarms - uses reflected signal amplifier limited and mixed with transmitter signal and difference frequency then used for alarm tripping
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: G01S15/04
Filed: 1976-03-29
Abstract: The detector has an amplifier and a demodulator for the received signal, and retransmits it to an output connected to an alarm tripping device. The detector has also an amplitude limiter (10) for the received signal (7) which cuts off the whole amplitude modulation of the received signal. The signal is much amplified before limiting, so that the limited signal amplitude is sufficient for its retransmission. The limited signal (fr) and a reference signal (fs) derived from the transmitter (1) are applied to a product detector which delivers a frequency difference signal (tD) to the output terminal for transmission to the alarm tripping device.

Title: Radiation recuperator with cylindrical double-skinned shell - has cylindrical insulating partition between skins to reduce heat stress on outer skin
Inventor: TRAPPE ULRICH DIPL ING
IPC: F28D21/00
Filed: 1976-04-10
Abstract: The recuperator consists of an outer shell (1) fitted to a support (2) resting on foundation (3) which actually is the top part of the duct emitting the hot gases.
