Title: Combined colour camera and video recorder - uses charge coupled matrix with reduced line capacity reducing scanning frequency by one third
Inventor: KITTLER WOLFRAM DIPL ING DR
IPC: H04N5/765
Filed: 1977-01-17
Abstract: The video tape recorder system for use with colour t.v. cameras comprises a camera with a charge-coupled-device matrix and clock pulse driver (TG) and tape mechanism (M). The tape mechanism is synchronised to the rester scan via a phase comparator (P). The line capacity of the charge-coupled storage matrix is less than for a standard system. The scanning frequency is correspondingly reduced by this factor, e.g. 1/3rd and the speed of the tape transport during recording is also reduced by this factor. By using a storage matrix of 200 X 800 storage positions, a tape speed of 1, 33 metre/sec is possible. On playback, the video information is scanned at n-times frequency to obtain the full 5,5 MHz bandwidth.

Title: Failsafe shutter cocking mechanism with film feed block - has cam to inhibit block until shutter is cocked and full frame is wound on
Inventor: HOEPFNER CLEMENS
IPC: G03B1/16
Filed: 1977-01-19
Abstract: The camera has a single slider which cocks the shutter and winds the film on by one frame. A claw monitors the single sprocket hole per frame and operates a film feed block until each frame is exposed. The linkage is set so that the film has to be fully wound on before the film feed block can operate. The shutter cocking lever has a curved cam which blocks a catch on the film feed block lever, with the cam sliding over the catch until the shutter is cocked. The system allows the shutter to be cocked even when the film is ended, or if the film snags. Overstraining of the shutter mechanism is avoided.

Title: Central heating system operating method - using heat storage vessel on each storey with thermostatic control to regulate supply of metered hot water from central boiler
Inventor: BROCKERHOFF HEINRICH ING GRAD
IPC: F24D11/00
Filed: 1978-10-28
Abstract: The central heating operating procedure is for a boiler furnace serving an apartment block. The circulatory system is divided into separate sections, e.g. for each flat, each having its own heat storage vessel supplied with the same amounts of heat at the same time. The boiler is subjected to a cooling phase after the storage vessel charging phase. When a heat storage vessel has cooled to an extent determined by a thermostatic control assigned to that heating section, it is recharged from the boiler and the amount and time is separately registered. The economical use of a single boiler is combined with precise individual comfort level setting and metering. Residual heat from the boiler during the cooling phase can be used. Unoccupied flats can be left at a heat level to prevent dampness etc.

Title: Centrifugal compacting of fine granules - in rubber lined bowls replacing wheels on motor vehicle differential axle
Filed: 1978-11-11
Abstract: Fine granules with or without a binder are converted to large lumps of regular size by centrifugal action. Two centrifugal bowls replace the wheels on a conventional differential axle of motor vehicles which is driven by a reversible motor. Each bowl is lined with rubber which has honeycomb cavities to suit the desired shape of the final prod. This a simple and low-cost drive which saves power because the kinetic energy of a spinning bowl can be used to accelerate a stationary bowl after it has been charged. A deflection of the lining towards the centre will remove the final pieces from the cavities of the lining.

Title: Coloured and heat-reflecting wall-covering material - of metallised film coated with infrared-transparent optically-pigmented lacquer (NO 3.11.80)
Inventor: PUSCH GUENTER DIPL ING DR
IPC: B32B15/04
Filed: 1979-04-10
Abstract: A heat-reflecting material for use as a wall covering or for insulating purposes comprises a backing of paper or plastic material coated on one or both sides with an infra-red- reflective metallic layer less than 30 nm in thickness. The metal is covered with a protective lacquer several microns thick, on top of which is a lacquer some tens of microns thick which appears coloured in wavelengths of 0.4-0.8 microns, but is largely transparent to wavelengths of 4-20 microns. The top layer may consist of an infra-red-transparent plastic material in which are dispersed optically-coloured pigments of a controlled particle size which promote interference at wavelength around 10 microns to increase the infra-red reflectivity. The material combines good heat reflection with aesthetically pleasing appearance, and avoids the problem of electrical conductivity of the metallic layer.
