Title: Data transmission system between fixed beacon and vehicle - uses microwave transmitter and receiver for phase modulated signals reflected from vehicle
Inventor: ADOLFS FRIEDHELM DIPL PHYS
IPC: G08G1/0967
Filed: 1980-03-18
Abstract: The data transmission system between a fixed beacon and a vehicle such as a fire engine or police car includes a microwave transmitter and receiver at the beacon and on the vehicle. The data reflected from the vehicle to the beacon is a modulated wave. The reflected wave can be phase modulated, and can consist of three components of the wave, phase displaced by 120 degrees and having nearly the same amplitude. At the beacon is a microwave assembly forming a phase modulated reflector. Pin or varactor diodes are connected with a modulator control circuit which determines the timing sequence of the control signals. Two diodes can form a T member and are spaced at different distances from the reflectiv reflective short circuit connection of the microwave line. The sender/receiver on the vehicle uses a Gunn oscillator for the microwave transmission.

Title: Etched, close-tolerance layer resistor - uses nickel-chrome resistance material and variable dimension etching according to control strip measurements
Inventor: GOTTLOB HEINRICH DIPL ING
IPC: H01C13/02
Filed: 1980-07-17
Abstract: The dimensions of the etching mask can be varied and the distance from the layer during exposure adjusted to provide the required resistance value. The exposing area is smaller than the border and rebate areas between resistors. The dimensions of the masks are controlled by measuring a control strip of resistance material along the edge of the slice of the substrate. A substrate (1) is coated with a nickel-chromium resistance layer and then on top a copper contact layer. The exposure through masks to produce the required contact areas (2) and resistance areas (3) are dependent upon measurements made on the side control strip (12). The close tolerance high accuracy resistor is achieved by adjustment of the inclined resistor section (11) and the opposite end section (9). A further control is achieved using local measurement (13) and local etching if required.

Title: Heat treatment of amorphous alloy films - esp. to remove magnetic dis-accommodation in magnetic recording heads
Inventor: SENNO HARUFUMI
IPC: H01F41/22
Filed: 1980-09-04
Abstract: The film is heated in a directional magnetic field which causes the suppression of the magnetic anisotropy induced in one plane. In the pref. process, the film is heated below its Curie temp., and in a magnetic field with a direction altering continuously in a plane parallel with the plane of the amorphous film. The direction of the magnetic field may be at 90 deg. w.r.t. the plane of the film. Another pref. process consists of heating the film to below its crystallisation temp. (Tc) in a magnetic field at 90 deg. to the plane of the film, and then heating the film again to below Tc in a magnetic field with a direction altering continuously in a plane parallel with the plane of the film. Amorphous alloys of the type Fe5C070Si15B10 are normally metastable and undergo magnetic disaccommodation; this defect is eliminated.

Title: Double tubular time lag fuse - has inner tube made of high thermal conductivity, low shock resistance material and outer tube with complementary characteristics
Inventor: AKIYAMA FUMITAKE
IPC: H01H85/38
Filed: 1980-09-22
Abstract: The disadvantages inherent in fuses which contain arc-quenching fillers in the fuse tube can be eliminated by fuse construction which does not require the use of arc quenching fillers. Yet, the fuse exhibits excellent breaking capacity and time-lag behaviour, and an overload current can be interrupted in a fraction of a second without explosion of the tube and while maintaining the stability of the fuse. The fuse comprises a fusible element (1) such as a conductor metal wire, and the like, disposed within an inner tube (3) which is, in turn, disposed within an outer tube (5) which is coterminus with the inner tubular member. The ends of the tubular members are capped with a pair of ferrules (7,7) to seal the double- tubular fuse while maintaining electrical contact with the fusible element. The fusible element is thus disposed within the empty tube (3) and no arc-quenching filler is employed. The inner tube is of a group comprising fosterite, steatite or talc, and the outer tube of cordierite or lithcium ceramic.

Title: Building ventilation waste heat recovery system - uses discharged air to evaporate heat-transfer liq. for subsequent recondensation
Inventor: BRANDT HANS-WALTER DR
IPC: F28D21/00
Filed: 1980-10-18
Abstract: The system recovers waste heat when ventilating buildings with warm air, this being delivered at the bottom and discharged at the top. The discharged air is used to heat an evaporator for a liq. heat-transfer medium, this then flowing through a downpipe and condensing at the bottom of the latter at a temp. higher than at the top. It is then returned to the evaporator, the heat released at the condenser being used to pre-heat the incoming air. Part of the liq. medium can be tapped off before the evaporator and then injected into the top end of the downpipe, or alternatively, a different liq. can be injected at this point, and separated again after condensation of the medium.

Title: Grading electrostatically charged powders esp. of plastics - using controlled humidity in carrier gas stream conveying powder through sieve
Inventor: SMIGERSKI HANS-JUERGEN DIPL IN
IPC: B29B9/16
Filed: 1980-10-31
Abstract: An improved method of grading electrostatically charged powdered material, esp. plastics powders, in the presence of a moving gas stream consists of subjecting the powders to an alternating voltage corona and simultaneously maintaining in the gas phase a humidity below the saturation level, more specifically a relative humidity of 20-80%. Used esp. for the grading of PVC or polyamide powders for use in melt coating processes, such as fluidised bed sintering, flame application or electrostatic coating procedures. The method results in a reduction of the very fine dust component entrained with the powder and also in considerably reduced tendency to adhere to the container walls and/or to form agglomerates.

Title: Baking oven door seal - with hooks attached to D=shaped seal ring for prestressed engagement
Inventor: KLEMENT JOHANN
IPC: F24C15/02
Filed: 1980-12-16
Abstract: A baking oven has between the muffle flange and the oven door a continuous seal of heat-resistant elastic material. The seal is fixed either to the muffle flange or to the inside of the door with a 5-10% mechanical prestress. The fixtures, e.g. hooks have a fair distance from each other, esp. in the corner areas. This permits the seal to expand, esp. when the muffle is kept at a higher temp. for a pyrolytic burn-off of the carbon deposits. The distortions of the seal are eliminated.

Title: Aeration apparatus for waste waters to be returned to surface waters, in particular for enriching utility waters with oxygen
Inventor: MEYER-KAHRWEG HELMUT DIPL ING
IPC: C02F7/00
Filed: 1981-01-31
Abstract: In an aeration apparatus for waste waters to be returned to surface waters, in particular for the enrichment of utility waters with oxygen, a cylindrical sluice gate arranged in a gravity tank is constructed with aerators which form a constriction in the cylindrical sluice gate. As a result, in the region of the constriction, a reduced pressure is produced which sucks in air via the aerators and as a result oxygen is added to the water. In order to avoid uncontrolled aeration, in particular the sucking-in of large air bubbles as a result of flow-dependent turbulence, a plurality of baffles are provided in the gravity tank which are arranged within the gravity tank radially to the cylindrical sluice gate.

Title: Low-waste E-I cut with an extended outer leg
Inventor: WAASNER BRUNO
IPC: B21D28/06
Filed: 1981-02-05
Abstract: There is a low-waste E-I cut, the E (5, 5') of which has equal parts and an extended outer leg, the I (6, 6') being shortened relative to the length of the spine by the width of the outer limb and two Es interlocking in mirror-inverted fashion being produced from a rectangle with just one punching cut. It is desirable if the length of the limbs can be selected independently of the length of the I cut and if the width of the outer limb is greater than half the width of the central limb. This is achieved by virtue of the fact that the width of the outer limbs is equal to the width of the intervening apertures and hence also equal to the width of the central limb and that both Is (6, 6') are punched out outside the rectangle formed by the two Es (5, 5'). <IMAGE>

Title: Frame structure composed of one or more connected right parallelepipeds
Inventor: TILLEY PAUL
IPC: A47B47/05
Filed: 1981-03-11
Abstract: The invention relates to a frame structure composed of one or more connected right parallelepipeds having rods which form the lateral edges and frame panels which are fastened within the said rods and relates to a design of the frame structure which permits the rapid and simple exchange and insertion of the frame panels, i.e. of all the frame panels, independently of the position of the parallelepipeds. This object is achieved by fitting an inner frame structure made of frame rods (1) with a supporting and insertion flange for the frame panel (5) and fitting an outer frame structure made of outside rods (3,6) which rest against the outside edge of the inner frame structure with guiding and holding projections for the frame panel (5), at least three outside rods (6) being removable to permit insertion of the frame panel. Once an outside rod has been removed, two frame panels can be inserted in each case, which panels are fixed by fastening the outside rod (6) in the frame structure. The application also relates to articulations which are designed to permit pivoting of the frame structures with respect to one another. <IMAGE>

Title: Device for synchronizing a clock having a torsion pendulum
Inventor: KUNER SIEGBERT ING GRAD
IPC: G04C3/033
Filed: 1981-03-19
Abstract: The invention relates to a torsion pendulum clock, in particular a so-called 400-day clock, having a mechanical drive of a torsion pendulum via an escapement, which is usual for this purpose, the torsion pendulum serving to provide the rate control. Such torsion pendulum clocks are characterised by very low energy consumption and relatively large time errors. It is proposed that a subassembly consisting of a crystal control circuit with an assigned coil and power source be assigned, in particular even subsequently, to such a torsion pendulum clock as an independent unit, with the result that a permanent magnet, which is likewise assigned and is to be mounted on the pendulum, is electrodynamically loaded by pulses delivered intermittently by the quartz control circuit and the torsion pendulum is thereby prompted to keep time. It is possible through the use of suitable components for the unit to be produced with small dimensions, and therefore to be arranged at a position which is not visually prominent in the region of the torsion pendulum of the 400-day clock.

Title: Signalling and switching device
Inventor: KORN JOEL DR ING
IPC: G08B29/12
Filed: 1981-05-23
Abstract: Device for a number of signal indicating elements and associated keys or switches, in which to each key or switch a threshold comparator (K1, K2, K3...) is allocated, the first input of which is connected to its associated key via one voltage divider each (R11/R13, R21/R23, R31/R33,...), the second input of which is connected to a first reference voltage source and the keys being connected to the summing voltage input of a latching-type comparator (DV) via one decoupling diode each (D11, D21, D31,...) and one series resistor each (R12, R22, R32,...), which are dimensioned in such a manner that the component of the voltage sum at the summing voltage input, when a key is operated, is smaller than the voltage of a second reference voltage source which is present at a second input of the latching-type comparator, that the component of the voltage sum, when a number of keys are operated, at the summing voltage input is greater than the voltage of the second reference voltage source, that the output of the latching-type comparator (DV) is connected to the second inputs of the threshold comparators (K1, K2, K3,...), in such a manner that when the voltage sum exceeds the second reference voltage, the output signal of the latching-type comparator (DV) is added to the first reference voltage and the key functions are thus not forwarded to the signal indicating elements. <IMAGE>

Title: Method for subsequent anchoring of bulkhead walls, and drill-receiving device and anchor for carrying out the method
IPC: E02D5/74
Filed: 1981-05-30
Abstract: In bulkhead walls which are secured by means of obliquely extending anchor piles and are used for harbour installations, there is a problem in providing additional anchor piles for safety reasons when the harbour bed becomes lower. For this purpose, a drill-receiving device is secured on the bulkhead wall under water, in order to drill into the bulkhead wall a hole for an additional anchor pile, so that the anchor pile can be rammed in from the direction of the water. The drill is designed as a hollow pipe which remains in the bulkhead wall and serves as a guide pipe for the subsequent anchor pile. The latter is designed as a hollow pipe and is provided on its head with an external flange which bears on the bulkhead wall in the end position of the anchor.
