Patent DE-3023042-A1 (DE)
Title: Wrapping stacks of roof tiles in plastics foil - comprising folding foil around stack and sealing to form loop
Inventor: SCHADE KURT
IPC: B65B9/02
Filed: 1980-06-20
Abstract: The stack or package is brought along a path and against a tensioned length of foil extending transversely across its path. Deflecting and wrapping devices then wrap the foil around the remainder of the package, cut off the foil from the feed sheets and bond the ends together to make a fully enclosed loop of material around the package. The portions of foil now cut from that wrapped around the package are again brought together to form a new sheet for the next package. Pref. two sheets of foil are supplied from two separate feed reels, one of these at one side and the other at the opposite side of the machine. Foil is pref. seal-welded together. Used esp. for banding stacks of roofing tiles. The arrangement enables the expense of a hot-shrink wrapping plant with its energy consumption to be eliminated, while still retaining the advantage of banding with plastics foil as opposed to metal bands. It is partic. suitable for use in a plant where hot-shrink wrapping has previously been used.

Title: Double evaporator for two heat pumps - has two coils and water injection tubes at opposite ends of three compartment housing
Inventor: DOEBELIN PETER
IPC: F25B39/02
Filed: 1980-06-20
Abstract: The double evaporator for two heat pump circuits has its two coils (5) housed inside a cylinder (1) through which water is circulated, forming a heat exchanger.

At the centre of each partition is a connection (14,15) for an injector tube (3) discharging into a compartment housing a coil. The water is delivered through spray openings (16) at the conical tip of each tube towards the outer end (6) of the cylinder and is then discharged through an outlet connection (17) at the top, adjacent to the inlet connection. Each injector tube is supported along the axis of a coil.

Title: Protection circuit for TV horizontal deflection circuit - has threshold resistance and capacitance, with protective diode between transistor and line transformer
Inventor: RICKEN HEINZ-GUENTER
IPC: H04N3/185
Filed: 1980-07-28
Abstract: The horizontal deflection circuit for a TV receiver includes a switching circuit (1) with a protection circuit (2) in series with the winding (6) of the line transformer (3). The switching circuit has a thyristor (5) in parallel with the switching transistor (4) and the transformer winding. A threshold voltage is developed between the angle of the thyristor and the base of the transistor across a parallel resistance (7) and capacitor (8), to give a required time constant. The protective circuit in series with the transformer winding includes a diode (10) with a parallel bridging resistance (12) in series with a second resistance (11) to prevent a short circuit of the winding when the thyristor conducts. The parallel resistance limits the voltage on the base of the transistor during the flyback period.

Title: Vehicle steering guidance system using buried cable - uses evaluated displacement of vehicle axis from cable to determine required steering angle
Inventor: RUBEL ERICH DIPL ING
IPC: G05D1/02
Filed: 1980-08-29
Abstract: The buried guidance cable is supplied with an AC voltage to provide a magnetic field which induces voltages in antenna coils mounted on the vehicle. These induced voltages are dependent on the sidewards displacement (g) of the vehicle central longitudinal axis (20) from the cable and are fed to an evaluation circuit supplying an output to the steering control. The latter has a proportional-integral-differential regulator adjusting the steering angle (beta) with the required steering angle dependent on the evaluated sidewards displacement (y), the differential of this displacement (y) and the integral of this displacement, each multiplied by a respective factor dependent on the vehicle speed.

Inventor: SCHILDT WALTER C
IPC: F16H55/56
Filed: 1980-10-03
Abstract: One or two plastic bushes (70, 72) are inserted between the hub (12) and the sleeve (36) longitudinally displaceable on the latter. Each such bush has a U-shaped bridging part (90) which is connected in one piece to the remaining bush parts and which projects into a keyway (63) of the hub or sleeve, and a key (60) which is firmly seated in a keyway of the other of these two parts. The bush is provided, preferably diametrically opposite the bridging part, with a continuous longitudinal slot (76) and has an annular rib (78) fitting into an annular groove (80) present in that part in which the bush is to be retained axially. The bush or bushes (70, 72) reduce the frictional resistance and the wear of the faces of the hub (12), of the bush (36) and of the key (60) which are located opposite one another and which are displaceable relative to one another. <IMAGE>
