Title: Heated bird bath with heater and seed dispenser - has dispenser stood in bath in cold weather to define drinking trough
Inventor: KEIDERLING GEORG
IPC: A01K39/04
Filed: 1975-09-01

Patent DE-2619414-A1 (DE)
Title: Sound control for cine camera - performs fadein and fadeout using transistorised logic control amplifier
Inventor: ROTH JOHANN
IPC: G03B31/02
Filed: 1976-05-03
Abstract: The sound/cine camera has two modes of control; one to vary the aperture w.r.t. the incident light on a photocell and one to alter the gain of an audio amplifier at the start and end of each scene so that the sound is applied smoothly and faded out at the end of the scene. The audio control is linked to the exposure circuit in such a way that when the release button is pressed the gain of the amplifier is increased over a short period. When the release button is released then the film runs on for a short time, while the sound is faded out by dropping the amplifier gain. The system eliminates abrupt sound track recording and provides a smoother film.

Title: Tube bundle for heat exchanger in nuclear plant - has hexagonal blocks around tube ends in honeycomb pattern forming tube plates
Inventor: SCHNEIDER KARL-UWE DIPL ING
IPC: F28F9/18
Filed: 1976-11-26
Abstract: Mfr. of a heat exchanger tube bundle composed of parallel, straight tubes, on the principle of a tube plate at each end of the bundle, is as follows. Each end of each tube is inserted into a hexagonal prism having a central bore and is connected to the prism by a seam of weld or solder. The hexagonal prisms are arranged in a honeycomb pattern, their faces abutting one another, adjacent prisms are connected together by a weld seam or solder seam, so that the prisms themselves constitute the tube plate or a part of it. Used partic. for closed gas turbine circuits of a nuclear power plant, where all the circuit components may be contained in an integrated layout in the pressure vessel itself. Used partic. for a tube bundle of ceramic material. A number of tubes of small dia. can be economically combined to tube bundles with a close spacing between individual tubes, enabling compact heat exchangers to be produced. In particular a large number of tube bundles can be rapidly assembled for a large plant operating at high pressure differences. The mfr. of large, expensive forgings for the tube plate is unnecessary. The prisms themselves can be made from drawn material. The method is also suitable for large-dia. tubes with a large spacing.

Title: Slide type ski binding with release mechanism - has roller guides which move laterally relative to ski and act exclusively with release mechanism
Inventor: ZOOR REINHOLD
IPC: A63C9/085
Filed: 1976-12-27
Abstract: The ski binding with safety release mechanism uses a slide (3) which moves laterally relative to the ski and inc. a low friction slide guidance system. The arrangement works independently of the shoe profile, with the release mechanism acting exclusively on the side. A sole-gripping claw is mounted on the slide. The slide (3) can be withdrawn completely from the ski. Connecting cables may be used to prevent complete severance and the slide serves as the shoe support plate. The releas mechanism locks the slide in the operational position and inc. a shore retention claw. The guidage system may inc. idling rollers (13, 14), balls or built in runners which are appended to the ski, and may use freely translatable roller cages. The rollers may be mounted on a frame or a "circuit" type anchorage (2) with axies normal to the major ski plane. The slide edges are located by roller grooves and the release mechanism may be a rotary cam (28) with a flat (31) engaging a sprung buffer (34).

Title: Toy motor car for children - has driver and passenger sitting side by side each in transparent plastics cabin
Inventor: MASKANITZ GEORG
IPC: A63H17/26
Filed: 1977-01-26
Abstract: The toy motor car for children consists of a body with no windscreen or roof. The driver and passenger sit side by side in separate cabins of transparent plastic of semi-elliptical form. The body is made of sheet metal and plastic, the car being hand propelled. By replacing the windscreen and roof with semi-elliptical cabins for driver and passenger the danger of an accident is eliminated. It is thus much safer for young children than existing toy motor-cars.
