Title: Automatic AC mains switch - uses transformer monitor to disconnect entire house from street mains when all appliances are off
Inventor: FALK WERNER ING GRAD
IPC: H03K17/725
Filed: 1976-05-31
Abstract: The automatic a. c. switch disconnects a house's mains supply from the street junction box when no electrical appliances are switched on. This ensures that the house mains circuit has no voltage applied to it and thereby avoids current loss due to small earth and phase faults. Current flowing in the phase line is monitored by a transformer whose primary is in the line. The voltage to earth of the same phase line is also measured. The measured current and voltage are combined to determine the impedance of the house circuit, i. e. whether a load is connected or not and to operate a circuit breaker if no load is present.

Title: Pressure difference compensated torsion tube - is used to transfer measurement force between volumes using strain gauges and sensing
Inventor: NUERNBERGER WILHELM DIPL ING
IPC: G01L1/22
Filed: 1976-06-09
Abstract: A torsion tube device is for transfer of a measurement force from one volume to another where the volumes are at different pressures. It is designed to compensate errors due to the press. difference. The device may be used in fluid level measurement where the position of a float is converted into a rotation of the tube which is measured externally by optical, electrical, or pneumatic methods. The tube (3) is a hollow cylinder (3) with its open end (4) fitted into a seal in an opening (1) in the wall (2) separating the volumns. The measurement force (K) applies torque to the sealed tube end (5). Strain gauges (7, 7') placed at 45 degrees to the tube axis on or in the tube are connected in a circuit so as to compensate the static press (P1) signal component.

Title: Carburettor with warming up system - has throttle depression transfered to secondary air intake by thermal switch
Inventor: MUNDIL WALDEMAR DIETMER
IPC: F02M1/00
Filed: 1976-07-26
Abstract: The carburettor is of the compound down draught type. It has a thermostatically operated choke flap situated in the primary air intake. The primary air intake contains a throttle valve actuated by the driver and the secondary air intake contains a throttle located downstream to a venturi and a fuel jet, and opening subject to manifold depression. Depression behind the two throttle flaps increases rapidly as soon as the engine is started to open the choke flap slightly via the depression capsule and to close an electric contact to heat a resistance. The resistance heat acts on a bi-metal disc controlling a depression connection between two channels leading to two pneumatic elements.

Title: Gear wheel with speed synchronising surfaces - has tapered ring carried on wheel sleeve to provide frictional rotation and assist meshing
Inventor: WINTER AUGUST
IPC: F16D23/06
Filed: 1977-03-30
Abstract: Two spur gear wheels (20, 40) are located on a drive shaft (10) and are normally free to rotate on it. A flange bush (11) which is keyed to the shaft carries a slider collar (12) by spur gear teeth. A tapered synchronising ring (22, 42) is located on a tapered sleeve on each gear. wheel. When the slider collar is moved towards a gear wheel, the synchronising ring is pushed onto the location taper so that the resulting friction rotates the gear wheel. The coupling collar can then be moved further until it engages the teeth (21) on the gear (20) and the centre flange of the drive shaft.

Title: Continuous cutter for endless synthetic filaments - has pressure roller intensifying centrifugal force acting on rope of filaments
IPC: D01G1/04
Filed: 1977-04-07
Abstract: The efficiency of a continuous cutting machine for a tow of endless synthetic filaments is improved. The cutter consists of a housing in which blades are spaced out axially with their cutting edges directed radially inwards. The spirally wound tow of filaments lies against the cutting edges and is pressed on to them by centrifugal force. Depending upon the speed of delivery and the characteristics of the filament, it is neither necessary nor possible, simply to cut the fibres by centrifugal force alone, and a pressing roller is fitted accordingly inside the cuter housing where it is positioned at a short, constant distance from the radius of the knives. Depending upon the speed of delivery and the speed of rotation, the tow of filaments is cut either by centrifugal force ro by the additional pressure of the rolleR.

Title: Airline ticket printing machine - has timing control to cut max. number of tickets with min. strokes from standard blank
Inventor: BARTSCH HERBERT J
IPC: B41L1/32
Filed: 1977-04-05
Abstract: The machine for printing air-line tickets is supplied with paper with transverse folds at twelve inch spacings. This enables three tickets each four inches long to be cut from each section lying between consecutive folds. When tickets of 3 1/2 inches or 3 1/4 inches have to be cut the machine has to make twice the number of cuts in order to remove the scrap strip. The additional number of cuts can be reduced by retiming the sequence of cutting so that three shorter tickets are cut one after another leaving only one piece of scrap between the edge of the last ticket and the fold at the end of the twelve inch section.

Title: Foot-operated delivery unit for lubricating grease - has movement of piston drive linkage limited by pressure part and slide recess
Inventor: STAGGE DIETER DIPL ING
IPC: F16N11/08
Filed: 1977-05-20
Abstract: The delivery unit for viscous media holds exchangeable containers from which the medium esp. lubricating grease is conveyed to the lubricating point by foot-operation of a piston. During the compression stroke of the piston (2) the movement of the hinge piece (5) holding the piston is limited by a high pressure part (6). During the suction stroke an angled side piece (7) on the part (6) interacts with the hinge piece so that a short limb (8) of the piece (7) is guided in a recess in the piece and prevents the hinge piece from moving further on attaining its initial position.

Title: Flame spectrometer burner head - has movable pistons in burner chamber to control flame length and uses threaded bolts to control pistons
Inventor: KNOLL EMIL
IPC: G01N21/72
Filed: 1977-06-24
Abstract: A burner chamber (1) is defined by a chamber wall (4) through which a supply tube (5) passes. At each side are pistons (3) which are slidable to vary the length of the burner slit. Movement of the pistons is controlled by rotation of threaded bolts (2). The desired setting of the slit may be fixed by means of a retaining washer (8) cooperating with the side of the chamber (7) and by means of a spacer washer (10) and a knurled nut (9). For precise definition of the slit length, the pistons must have a projection (11) whose cross-section matches that of the split. This may be formed from a platelet stuck on the side of the piston.
