Title: Vehicle passenger safety belt - has anchoring points on top and bottom of door which is hinged on parallelogram linkage allowing free passenger access
Inventor: ALBERSINGER GEORG
IPC: B60R22/04
Filed: 1976-12-30
Abstract: The safety belt arrangement in a motor vehicle uses a conventional three point anchored automatic belt. The upper anchoring point is on the door strut and the second anchoring point in the middle of the vehicle. The automatic belt reeling device and the third anchoring point are held on the door lower edge. A special door hinge is used to ensure unobstructed entry into the vehicle by passengers. The hinge is a parallelogram linkage designed so that it ensures parallel outward movement of the door relative to the longitudinal axis and it carries the belt forwards. The lap belt is moved upwards by a cable mechanism which is actuated by the door hinge on opening the door. The actuating cable is passed over the pulley at the upper edge of the door.

Title: Paint spray head jet width control system - has compressed air discharge holes on each side of slot for varying pressure
Inventor: SCHIEMANN OTTO
IPC: B05B7/08
Filed: 1977-02-10
Abstract: A nozzle for a paint spray has a circular raised zone (1) in the centre, with an oval slot (3) for discharge of the paint to give a flat jet. Above and below are flat compressed air jet slots (4) which ensure a fine spray. At each side, two lugs project, with a set of compressed air discharge holes (6) which impinge onto the sides of the jet and also at an angle to the jet. These can be controlled to vary the width of the flat jet. In an alternative design, there are no flat upper and lower jets, so that a narrower jet can be obtained in conjunction.

Title: Jig for welding wheel rim blanks - where single loop induction coil provides welding current
Inventor: BERGER PAUL
IPC: B23K13/02
Filed: 1977-02-22
Abstract: Jig for seam welding a wheel rim blank or similar object with a high frequency welding current of several kHz min, fed through an induction loop which only passes once round the joint surfaces to form a gap in which the latter are located. Each long side of the gap has a bar (a) carrying most of the current and made of material with good electrical conductivity; and each bar is fixed on a back-up rail (b) made of material with poor conductivity and contg. 1 coolant channel. The loop forms a gap with larger width at the ends than in the middle so a uniform tep. is obtd. for welding, and the loop pref. provides the optimum compromise between high magnetic field in the blank and min. opposed inductive influences in the long sides of the loop. Provides optimum welding of wheel rim blanks using e.g. 150 kW power.

Patent DE-2737624-A1 (DE)
Title: Extinction of incandescent coke by spraying with water - in enclosed space, eliminating emissions to atmos., incorporating heat and materials recovery
Inventor: BROEMMEL WALTER DIPL ING
IPC: C10B39/04
Filed: 1977-08-19
Abstract: Extinction of incandescent coke is effected by spraying the coke with water producing steam and condensing the steam produced in an enclosure isolated from the atmos. The steam is condensed by mixing and the gases remaining are taken out without being emitted to the atmos. The coke charges are brought in trucks on rails into the enclosure under a cooling column and the charge is sprayed with water from nozzles. The steam formed is condensed and the condensate is discharged, the heat of condensn. being recovered and re-used. The gases are freed from noxious substances and re-used. The heat of condensn. can be used to vaporise waste waters from the coke prodn. and to condense the vapour and supply water for industrial use. The emission of gas, vapours and dust during the extinction of coke is completely eliminated. The prodn. of materials capable of being treated and re-used, and the recovery of heat, are facilitated.

Patent DE-2758596-A1 (DE)
Title: Inert mass coupling mechanism to base - has gear train transmitting torque to mass in both rotation directions
Inventor: STEHLIN BERNHARD DIPL ING
IPC: F41A27/24
Filed: 1977-12-29
Abstract: The mechanism couples an inert mass, such as a firearm, to a supporting base, such as a vehicle. The mechanism allows the firearm to tilt in relation to the base about one or more axes under the action of a drive without a self-locking characteristic. Between the mass and the base there is a gear train whose output is coupled to the mass, and which can transmit torque to the mass in both directions of rotation, but has a self-locking action the opposite way. The input of the gear train when the tilting drive is operating can be driven in the direction of relative movement between the base and the mass.

Patent DE-2828551-A1 (DE)
Inventor: KIEFER ALBERT
IPC: H04Q9/00
Filed: 1978-06-29
Abstract: In the monitoring of alarm contacts which in each case supply a fault or operating signal relating to a heating, ventilation, lift, lighting, or power system or the like, numerous signal transmission circuits are required in the building control system. The alarm contacts are usually combined at main data points close to the object, whence monitoring in multiplex mode is carried out along with transmission to a secondary station and from there to a central station. In known systems, numerous lines are provided between the main data point and the secondary station, along with a complex multiplexing device, moreover creating susceptibility to interference signal injection. The object is to reduce the cost of the transmission and to improve immunity to interference in the transmission from the contacts to the secondary station (2). For this purpose, the alarm contacts are combined in an alarm matrix (1) and are decoupled by means of diodes from one another and from interference signals being passed on. <IMAGE>

Title: Membrane type filtration unit - having series of constrictions on clean fluid side which induce low pressures and cause flow of fluid through membrane
Inventor: SIEGEL ROLF
IPC: B01D61/14
Filed: 1978-08-03
Abstract: Filtration process has two fluid streams, liquid or gas, flowing countercurrent to each other either side of a medium esp. a filter or dialysis membrane. The flow of the fluid not being filtered is subjected to a series of reductions of the flow cross section. These reductions with the associated acceleration in velocity induce a region of low pressure below the membrane. This causes a flow of fluid through the membrane while the flow of unfiltered fluid sweeps the membrane and prevents the accumulation of solids. Used for filtering gases and liquids. Avoids the problem of the filter becoming blocked with cake after a period the need for a high pressure drop across the filter membrane, and the need for special mountings for the filter.
