Title: Transport feed for sensitive undeveloped film - has belt driven roller free to move film against contact roller to generate contact pressure proportional to feed resistance
Inventor: ZIEGLER GERHARD ING GRAD
IPC: B65H20/00
Filed: 1979-09-27
Abstract: A transport feed mechanism for undeveloped film is designed to maintain contact pressure at a min. value consistent with reliable transportation.

Title: Worn guide bushing extracting device - uses expanding bushing with radially projecting sharp edges
Inventor: LUTTMANN FRIEDRICH
IPC: B25B27/067

Title: Removing smells from fat-laden air by filter - with replaceable layer section preceded by spray section
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/02
Filed: 1980-01-24
Abstract: A filter is a combination of wet and dry chemisorption sections. The wet section is a normal spray of water with dissolved additives. The air, with liquid drops removed, then passes through a stack of superimposed compartments contg. inflated calcium-aluminium-silicate in porous bags, the granules being pref. impregnated with potassium permanganate or other reactive fluids. Finally the air passes through a layer of activated charcoal above which is a suction fan. The bags can be readily replaced when exhausted. For fish-frying establishments or food-smoke rooms. The air does not have to be heated to destroy the smells. The porous granules absorb most of the residual fat-bearing water, which extends the life of the expensive charcoal layer.

Title: Dimmer circuit for fluorescent lamp - conducts phase or pulse width or frequency of DC=AC converter to modify intensity
Inventor: LIMLEY ROBERT DIPL KFM
IPC: H05B41/392
Filed: 1980-01-24

Title: Cooling system for totally enclosed motor - has internal air ducts adjacent to external ducts in the stator frame
Inventor: BOEHM FRANZ ING GRAD
IPC: H02K9/06
Filed: 1980-06-04
Abstract: The machine has forced air circulation inside the stator frame. Air is forced by an internal fan through ducts (5E) in the stator frame joining the end winding compartments. Parallel to these ducts (5E) are further ducts (13) through which air external to the machine is forced by an external fan. The stator frame typically also has external axial ribbing (2A) giving additional cooling surface which is in the external air stream. The method of construction is suitable for use in cast frames. The necessary external, and also internal, ducts can be formed by casting tubes into the frame. By arranging the tubes from the respective air circuits clost together the effective heat transfer from internal to ambient air is improved.

Title: Hand soldering iron contg. thermocouple for temp. control - where end of thermocouple is very near working end of solder bit so overheating is avoided
Inventor: VEHMANN LUTZ
IPC: B23K3/03
Filed: 1980-06-19
Abstract: In the iron handle is a heater cartridge contg. an axial hole for a metal tube (I) which projects into an axial holder in the soldering bit so the thermocouple is very near to the working surface of the bit. (I) is pref. made of steel, and contains one insulated wire made of constantan and spot welded to the end of (I) to make the thermocouple. Because the thermocouple is extremely near the working surface of the bit, rapid response to temp. change can be achieved and the bit kept at an accurate, desired temp. This is important, e.g. when soldering components onto printed circuit boards.

Patent DE-3042631-A1 (DE)
Title: Flameless atom absorption analysis - using separate heating currents for atomisation and sample chamber preheating for interface sealing
Inventor: SPERLING KLAUS-RICHARD DR
IPC: G01N21/74
Filed: 1980-11-12
Abstract: The method is for examination of specimens using flameless atom absorption measurements and involves heating the sample electrically in a tubular sample chamber (2) until it forms a cloud of atoms. A measurement beam (1) is passed through the atomic cloud. The appts. enables a seal to be maintained at the transfer between the atomising and sample chambers despite the large temp. difference and without allowing recondensation at cold spots. This is achieved by using separate circuits for preheating the sample chamber and for causing the atomisation. The atomisation takes place after the sample chamber has been preheated and involves removing or heating a cooling body applied externally to the actual atomisation zone.

Title: Control markings for copying narrow gauge cine film - reducing perforations temporarily to indicate frames requiring colour and/or exposure adjustment
Inventor: CASPAR WOLFGANG
IPC: G03B27/73
Filed: 1980-12-11
Abstract: The control markings (8) are applied between the regularly spaced markings (5) comprising the sprocket holes or the timing markings. The control marking have round holes smaller than the regular markings and the sensor moves at right angles to the plane of the film. The perforations are between the edge of the film and the frames and are not easily damaged. The process control monitors the regularly spaced markings and inhibits the sensor drive at these regular intervals to minimise perforation damage.

Title: Device for insulating a coaxial cable end
IPC: H01R9/05
Filed: 1981-01-24
Abstract: In the case of a device (1) for insulating a coaxial cable end (2 or 4) with the inner conductor (5) and outer conductor (6) being bridged via a fixed, predetermined resistor (14), it is intended to create a solution by means of which a fixed non-reactive resistor is provided between the inner cable and outer cable of a coaxial cable, additional manipulation to fit the resistor being obviated and, at the same time, watertight termination of the cable end being ensured. This is achieved in that electrical contacts (11 and 10 respectively) which necessarily come into contact with the respective conductors (5 and 6 respectively) in the in-use position are provided inside a prefabricated, cap-shaped sleeve (9) consisting of material which can be shrunk by heat, these contacts (10, 11) being electrically conductively connected to one another via a predetermined resistor (14). <IMAGE>
