Title: Spinning regulator mechanism - for automatic web density control in carding and combing
Inventor: BECHLENBERG HEINZ DR-ING
IPC: D01G23/06
Filed: 1971-03-18
Abstract: A regulating mechanism to keep the amount of fibre constant on the output or input of a carding, combing, or drafting machine. The main A.C. motor drives the main cylinder and the first of the output rollers. A direct current motor drives the second output roller. After this roller is a measuring device, whose output controls the speed of the D.C. motor by the armature. The D.C. motor drives the final output roller via a dual magnetic clutch, the other half being connected to the first roller driven by the main motor. To start the machine the first and second output rollers are driven in tandem with no variation, but when up to speed, the switching is varied on that the control circuits work. The process is reversed during stopping.

Title: Plastics bottle bottom - with concave centre to give firm standing ring
Inventor: ROSENKRANZ OTTO
IPC: B29C67/00
Filed: 1972-05-08
Abstract: Stiffening the bottom of a blown plastics vessel, esp. a bottle, consists of first forming an outwardly convex bottom to the bottle and then doming this inwards to form a circumferential seating ring upon which the bottle will stand. To produce the desired concave shape, a die is pref. applied to the bottle bottom either after reheating, or simultaneously while still in the blowing mould, in the latter case, the die slides in a hole at the end of the mould. The method enables a firm recess to be achieved which resists internal pressure, provides a standing ring of satisfactory diameter and results in low pending moments in the region of this ring.

Title: Coolant for gas generators - for life-rafts/inflatable cushions is solid liberating gas at high temp
Inventor: SHAW GRAHAM CAMPBELL
IPC: C09K5/14
Filed: 1972-07-06
Abstract: The coolant consists of finely-divided solid material (I) which decomposes at ca. 1260 degrees C. with the formation of CO2 and steam and consists of metal bicarbonate, hydrated salt or oxalate salt.

Title: IC engine with flap valves - combustion chamber sealed by flaps and drive conveyed directly by specially formed body
Inventor: MENTRUP WILHELM
IPC: F02B75/02
Filed: 1973-12-14
Abstract: To increase the turning moment of an internal combustion engine working on the Otto principle with lesser number of revolutions it is suggested that the combustion chamber is sealed by flaps. The centrically arranged star-shaped body on the drive shaft conveys eight working strokes with a four flap engine for only one rotation. The moment is thus conveyed directly onto the drive shaft. The ends of the flaps are fixed on axles and are arranged in a circle concentrically around the centre of the engine. The cantilevers of the flaps convey the moment from the working stroke to the drive shaft. All the cantilevers ride on the star-shaped body which serves as the motion conveying member.

Title: Stress-crack-resistant waterproof concrete ceiling construction - with slabs concreted onto beans subjected to prestressing during concreting
Inventor: SANDQVIST SUNE ALLAN
IPC: E04B5/23
Filed: 1974-03-05
Abstract: The purpose is to produce concrete ceilings with improved resistance to stress flaws, and thus with improved sealing against water penetration, esp. in park buildings and others exposed to severe weather conditions and drastic temperature fluctuations. A concrete slab, of ceiling or ceiling sections size, is produced by concreting on top of one or more beams which become anchored to it, these being exposed to prestressing forces during the concreting process, and exposed to tension on the side on which the concrete is to be set. The concrete slab is pressure-loaded by means of the beams when the forces are withdrawn after hardening. One or more such slabs are fitted on supports at the ends, to form a pressure-prestressed, sealed ceiling structure. This may be done directly on site.

Title: Orthopaedic arm supports for typewriter - are designed to eliminate shoulder cramp and tendon inflammation
Inventor: COENEN FRANZ-PETER DIPL ING
IPC: A47B21/03
Filed: 1974-06-22
Abstract: The orthopaedic arm supports extend outwards from the machine. Each arm support is hinge-linked to the typewriter and not to the seat on which the operator sits. The support begins at the wrist at a point which is the optimum position as regards height, distance and lateral displacement relative to the keyboard. The support extends back as far as the elbow and thereby covers the whole of the lower arm. A water bed or air cushion support is spreferred since it does not give rise to pressure points. the support can be attached to the metal plate which simultaneously serves as the base for the typewriter. The end of the support on which the elbow rests should be adjustable both laterally and vertically.

IPC: F16H19/00
Filed: 1974-08-06
Abstract: In a mechanism for controlling the movements of a dirigible scanning head, movement about one of three orthogonal axes is imparted to the head by means of a pair of flexible straps which are fastened to the head at opposite sides of said one axis and extend along a part-circular track at the back of the head that is centered on said one axis. The straps are wrapped around respective rollers mounted on a carrier that is itself displaceable in a direction generally along the track by a coupling to an endless flexible band driven by an electric motor-drive. The straps and the drive means for them are carried by the head for rotation with the head relatively to a support member about a second of the three axes.
