Title: Pressure and delivery control for piston pump - has pressure sensitive adjuster to position movable brushes of pump driving motor
Inventor: STAHLKOPF FRIEDRICH
IPC: F04B49/20
Filed: 1978-06-08
Abstract: The arrangement is for varying the pressure and delivery of a piston pump, particularly when handling solids-carrying or other high-viscosity liqs. so that delivery is reduced as pressure increases, e.g. when delivering to a filter press. The pump is driven by a commutator motor (3) with adjustable brushes (3a). The pressure downstream of the pump can be used as the input quantity to actuate a positioning element (7, 7') which is connected (8) to the cylinder (1) or the outlet manifold (1d) or the air vessel (6). The piston of the element acts as a cable (14) to adjust the angle (phi) at which the brushes are set.

Title: Labelling method for cassettes - uses rotary head with label holders fitted with suction holders and suction positioning devices
IPC: B65C9/22
Filed: 1978-06-14
Abstract: The labelling method is for flat objects such as a sound or video cassettes. The labels are taken from a storage stack by label holders fitted with suction and positioning devices using vacuum pressure and are subsequently made adhesive. The labels are moved in stops from the stack to the application point by a rotating head fitted with radially movable label holders. At each stop of the rotating head the labels are taken by the lable holders and made adhesive, the objects are then lifted from a continuously passing conveyor chain to apply the labels through the radial approach of the corresponding label holder and finally of the vacuum is cut off.

Title: Checking calibration of semi-conductor smoke detectors - by altering operating temp. and noting variation in resistance pattern
Inventor: DITTRICH JUERGEN
IPC: G01N33/00
Filed: 1978-08-10
Abstract: The sensitivity and calibration of smoke detectors with a semiconductor element i checked by deliberately altering the operating temp. The element normally operates in the range 180-360 degrees C and its resistance alters in the presence of smoke. This resistance is continuously monitored. For a period of 0.5-3 min. the operating temp. of the sensor is changed over a range of 10% and is then finally brought back to the operating temp. The variation in the resistance over this period is then compared to a standard variation curve using e.g. microprocessor. For use with smoke detectors, it allows their sensitivity to be checked with them in service and avoids the need to use special sample gases.

Title: Image field scanning system for IR viewfinder - uses reflective scanning element and pivoted field mirror for reflected beam
Inventor: RIEDL GUENTHER DIPL ING
IPC: G02B26/10
Filed: 1978-09-26
Abstract: The scanning system uses at least one reflective scanning element(1) with an input lens(3) directing the light beam onto the scanning element(1) and a focussing lens(6) directing the reflected light beam onto a photodetector(5). A second focussing lens(7) lies between the scanning element(1) and the first focussing lens(6), with a field mirror(9) at the focus of the second focussing lens(7). This field mirror(9) can pivot about an axis perpendicular to the scanning direction in sync. with the movement of the scanning element(1), so that the position of the beam reflected from the field mirror(9) remains still independent of the position of the scanning element(1). Pref. the latter comprises a planar mirror pivoted about an axis(2) perpendicular to the scanning direction.

Filed: 1978-10-11
Abstract: Heat-resistant industrial floor block based on concrete and cement-bound, formed from a concrete mixture with comminuted blast-furnace slag as additive. From 40 to 60 % by weight of the additive is composed of a coarse component consisting of chippings of high-strength granulated slag blocks, in the grain-size range of between 14 and 16 mm, and from 60 to 40 % by weight of said additive is composed of a fine component which consists of slag granules and/or crushed granulated blast-furnace slag, in the grain-size range of between 0 and 4 mm. If a concrete mixture of this type is used for producing the concrete blocks, the latter have a surprisingly high impact strength and wear resistance as well as heat resistance and can be used as industrial floor blocks even in areas subjected to heat. A blast-furnace cement is preferably used as the cement.

Title: Route marking detection in railway guidance system - using difference in operation frequency of adjacent guidance loops
Inventor: SCHULTZE KONRAD-M ING GRAD
IPC: B61L3/22
Filed: 1978-10-14
Abstract: The recognition system uses a series of line conductor guidance loops each of which is supplied by a transmitter incorporating a quartz oscillator. The quartz oscillators in the transmitters coupled to two adjacent loops operate at slightly different frequencies, so that the base operating frequencies for the two loops differ by a fixed amount, with this different detected by an evaluation device carried by the vehicle, to detect the transfer from one loop to another. Each detected transfer is used as a path marking indication. Further path marking indications can be provided in response to the vehicle crossing spaced crossover prints between the loop line conductors, the evaluation device responding to the 180 degree phase shift in the received signal detected at each crossover point.

Title: Hydraulic breech for automatic weapon - has larger and smaller pistons inside cylindrical chamber, with smaller piston passing trough partition
Inventor: ZEIS ALFONS GEORG
IPC: F41A3/90
Filed: 1979-05-28
Abstract: The hydraulically controlled breech for an automatic weapon has a chamber inside which travels a piston with a large section at the cartridge carrying end and a smaller intermediate piston. These pistons control the displacement of liquid from one end of the chamber to the other. At a position about half-way along the chamber, is a partition through which the smaller piston can travel. After this piston has passed through the hole in the middle of the partition, the liquid can then pass through the hole. A larger displacement of liquid is then controlled by the larger piston.

Title: Packaged unused bread conversion to animal fodder - by shredding, screening and pneumatic sifting to remove packaging
Inventor: WESSELER GERHARD
IPC: A23N17/02
Filed: 1979-06-25
Abstract: A machine to separate packaged bread which bas not been sold by a fixed date and is to be used for pig swill is used to remove paper, plastic or aluminium foil. A revolving shredding drum moves close to a grating, and a vibratory screen below the latter drops the underflow on an endless conveyor. A pneumatic separator with a fan impeller treats the screen overflow and only the beavier particles fall through a grating on the conveyor. This eliminates the beavy labour costs for manual unwrapping and disposal of the wrappings and makes the use of unsold packaged bread for animal fodder attractive.

Title: Pneumatic tyre esp. for high-speed motor-car - with blocks in three tread lines of specified shape for better aquaplaning
Inventor: FRERICHS UDO
IPC: B60C11/11
Filed: 1979-12-01
Abstract: A pneumatic tyre for motor vehicles, esp. for high-speed motor cars, has a tread which is defined by three peripheral blocks, sepd. by peripheral grooves. The blocks of the same line are sepd. from each other by thinner grooves with a mean inclination of 20 deg. transversely to the tyre, which alternate in direction from one line to the next. Each block groove is half the width of the peripheral groove and has the shape of an angular S.

Title: Gas sample extraction appts. - using injector for recycling and pump for branch sample to analyser
Inventor: WEBER RUDOLF
IPC: G01N1/22
Filed: 1979-12-15
Abstract: A device to take and analyse a gas sample from a heat exchanger, esp. from the cyclone preheater of the waste gases from a rotary kiln, consists of an injector which extracts a gas side stream and returns it to the duct at a point upstream. A pump branches off a test sample of the gas for an analyser. A blower in an auxiliary gas pipe feeds the injector. Solenoid valves, controlled by a unit coupled to the manual setter of the injector and to a pressure gauge, shut the test gas and the return circuit when a set vacuum is exceeded. This requires only short sampling pipes which are not likely to be clogged by deposits. The valves make it possible to blow out any occasional deposits.
