Title: Variable marking lines for hall floors - consist of crystals of temp. dependent colour and associated heating or cooling devices
Inventor: HOESS KLAUS DIETER
IPC: E01F9/594
Filed: 1976-05-06
Abstract: The panel or strip-shaped floor covering, as installed in sports halls, exhibition centres, hospitals or elsewhere, has one or more delineating lines on its surface for defining prescribed areas. These strip marks (9, 12) are made from crystals, or contain crystals (17), with colour dependent on their temp. and these are subjected to the influence of a heating and/or cooling device. This can be sited below the top flooring layer (3), running along the strip mark; or between the mark and the floor covering (5), where it can support the crystals, or form part of a flat sheath for them. At normal room temperature the strip marks can be virtually colourless. This enables the room to be used for different purposes, with floor marks varied as required.
Patent DE-2624824-A1 (DE)
Title: Simplified sound cine synchronisation - using coupled cassette recorders with rapid stop switched so that each has sufficient running up time before scene take
Inventor: MUETING BERND
IPC: G03B31/04
Filed: 1976-05-31
Abstract: The sound track of the cine film is transferred onto two cassette recorders with the recording taken on alternate scenes. The sound and vision are then synchronised for each scene and impulse markings applied to the sound track, with the start of each scene indicated by markings on the film. The recorders are used alternatively so that each one has sufficient time to run up to operating speed prior to each scene. The synchronisation is thus accurately set at the start of each scene.

Title: Diaphragm-type distribution pump - has lever moving diaphragm clamped by flange between upper and lower body sections
Inventor: GROGAN RICHARD P
IPC: F04B53/10
Filed: 1976-07-01
Abstract: The diaphragm-type distribution pump has top and bottom sections sealed to each other to form the body, the diaphragm (20) being clamped between them by means of its non-perforated flange, so as to form a closed chamber (22) between it and the top section. The volume of this chamber is varied by means of an actuating lever (26) bearing against the underside of the diaphragm and pivoting in the body. The lower part of the latter has an inlet port (36) leading from the fluid reservoir (34) to the joint face with the toip section, which has a hollowed-out-portion opposite it extending from the flange edge to the pump chamber. Thus the flange acts at this point as a flap valve opening upwards. There is also a delivery port in the upper section from the pump chamber to the upper side of the flange at another point, above a hollowed-out portion in the lower section allowing the flange to open downwards and the fluid to be discharged to atmosphere.

Title: Decanting centrifuge with rotating housing - has screw conveyor inside rotating at different speed and fluid outlet tubes on housing wall
Inventor: GRIMWOOD GEOFFREY LUTHER
IPC: B04B1/20
Filed: 1976-08-24
Abstract: The decanting centrifuge works with laminar flow. A rotating cylindrical housing has a tapered part rotating on a hollow shaft. Inside the housing a screw conveyer (24) with helical blades (22) rotates at a speed different from that of the housing. The helical blades are fitted to the hollow shaft (24) of the screw conveyer which at one end forms a chamber (28) with an opening (30) serving as an input opening for the dross to pass into the decanting space. The charging of the centrifuge takes place via inner hollow shaft (32). Due to the relative speed difference between the housing (10) and the screw conveyer the separated solid matter is moved towards the outlet. The housing (10) is fitted with several tubes (40) serving as a fluid outlet from the decanting space.
