Title: Protective gas atmosphere generator - consisting of radiant tube mantle acting as endothermic generator retort
Inventor: TUERK MANFRED
IPC: B01J19/14
Filed: 1973-12-21
Abstract: Endothermic gas generator uses radiant tube mantle as a retort for gas prodn. Air and gas are introduced in the reqd. proportions into flame tube which forms the holder for catalyst. The whole inside can be extracted by removing bolts in a flange. The device is esp. used for producing gas for furnaces requiring a carbonising atmosphere. The generator can then be one of the radiant tubes in the furnace enclosure. This avoids the use of a separately fired retort and allows for the continuous replacement of furnace atmospheres to avoid scaling etc.

Title: Single action key for space bar actuation - has built-in snap action spring for low operating force
Inventor: BACHINGER PETER
IPC: H01H3/12
Filed: 1974-02-01
Abstract: The space bar of a typewriter requires a single action input key of long length. The space bar key operates upon a preformed rod that is cranked at either end. The cranked ends of the bar are freely located in discs. The operating key bar operates freely upon the rod and trips a snap action mechanism formed by a spring. When actuated the bar moves through a initial distance before the snap action mechanism rapidly completes the required actuation. Upon release the return spring performs a similar function. The device may be adapted for general use with data processing equipment.

Title: Low boiling and total hydrocarbon measurement - by hydrogen flame burners, electro-meters and subtractive indicators
Inventor: POLI ALBERT A
IPC: G01N27/62
Filed: 1974-02-19
Abstract: In the supervision of air pollution it is desirable to measure quantitatively the share of the hydrocarbon fraction with a low b. pt. simultaneously with that of all hydrocarbons without this fraction. The sample is split into a part for a first detector to measure the total hydrocarbons; and a second part which has all hydrocarbons except those of a given low b. pt. removed in a reactor before it passes to a second detector. A combination of amplifiers deducts the low boiling fraction from the total value. In an analysis for methane in presence of strong fluctuations of the heavier hydrocarbon content, a simpler interpretation results from the deduction of methane from the total hydrocarbons.

Title: Switching and delay device - delivers two output voltages, depending on input signal being below or above threshold
Inventor: KOEPKE WOLFGANG
IPC: H04B1/46
Filed: 1974-03-29
Abstract: The first output voltage corresponding to the lower input signal blocks a signal path through an electronic switch, and the second unblocks it. When an input voltage drops below the threshold, the second output signal remains present until a capacitor in an RC circuit charged to a voltage above the threshold is at least partly discharged. The device is an integrated CMOS circuit with at least two gates. Input voltage is applied to the input of a first gate serving as the threshold switch. The first gate output is connected through a diode to the input of the second gate which, together with the RC circuit, forms a delay line. The RC circuit is between the second gate input and frame, and its output is connected to the electronic switch control input.

Title: Electromotor with speed selection for windscreen wipers - has air-cooled resistance wires switched into motor supply to alter speed
Inventor: HEGER SIEGFRIED
IPC: H02P7/285
Filed: 1974-05-17
Abstract: The electromotor with speed selection, for a vehicle windscreen wipers or fan, has a series of resistors switched as required into the motor supply lines. These resistors are formed by resistance wires. The resistance wires are mounted on the vehicle bodywork in the path of the air so that they are adequately cooled when the vehicle is moving. If the motor is used to drive a fan, then these wires are located in the air flow from the fan and are cooled by it. The advantage of using resistance wires lies in their being more easily cooled by the air flow than, say, ceramic-wire resistors.

Title: Manufacturing process for dovetailed parts of artificial teeth - female section is moulded from male section with which it is used
Inventor: HAKER GERD
IPC: A61C13/265
Filed: 1974-09-12
Abstract: The male part of the dovetail (of which one type is illustrated) is first moulded in metal from a master mould by a 'lost wax' ('lost plastic') process. It is then set in the mould which will be used for one part of the artificial tooth; this part thus acquires an exactly-mating female dovetail. The male section is tapered slightly for easier release from this mould; a tab on its back also helps. The reamining part of the artificial tooth is now fixed to the male dovetail. Other male shapes are also envisaged, e.g., a cylinder in place of the dovetail; and one with a long slit in the 'dovetail' to give some spring to the joint.

Patent DE-2552414-A1 (DE)
Title: HV thyristor bridge monitoring system - generates additional control pulse to which no address and so no output should correspond to check functioning of monitor
Inventor: LENSING BERNHARD DIPL PHYS
IPC: H02H7/12
Filed: 1975-11-22
Abstract: Trigger pulses are fed via a light guide (LA) to all thyristors and simultaneously to a counter whose output is compared with that of an address store. If parity exists an impulse passes to the supervisory unit which transmits a light signal via guides when a checking unit emits a coincident pulse indicating satisfactory operation of the thyristor. Each address is unique so that every thyristor is monitored in turn. To check that the monitoring circuits are functioning correctly an additional light pulse is generated at the input (L). The number of this impulse is n+1, but as the highest address is n there should be no corresponding output from the checking unit. The presence of output indicates a fault. Finally a reset impulse returns all counters to zero. By this means both thyristor and controls are cyclically checked.
