Title: Lighting system for bicycles
Inventor: RENTZSCH MANFRED
IPC: B62J6/00
Filed: 1982-04-08
Abstract: The invention relates to a lighting system for bicycles having a headlight and a rear light whose lamps can be operated in the travelling mode by means of a dynamo and when stationary by means of a separate auxiliary voltage source. The change-over from one mode of operation to the other is controlled electronically as a function of predetermined limit values of the voltage generated by the dynamo, the lamps only being operated on the auxiliary voltage source during a fixed time. During this fixed time, the lamps can be disconnected from the auxiliary voltage source prematurely by actuating a key and connected to the dynamo.

Title: Milk sample extraction appts. from delivery pipe
Inventor: EISMANN JOSEF ING GRAD
IPC: G01N33/04
Filed: 1982-06-12
Abstract: The arrangement for taking samples of milk from a delivery pipe (2) carrying milk from e.g a dairy farm container to a bulk transporter, has a branch pipe (5) connected through an adjustment valve (6) to the delivery pipe on the delivery side of a pump (3).  The branch pipe leads directly to the lower part of an intermediate container (1), which is connected through a return pipe (10) to the delivery pipe on the input side (11) of the pump.  The intermediate container is connected also to a sampling device (12), which has an outflow pipe (9) with non-return valve (14) connected to the intermediate container's return pipe. The sampling device has a valve housing which incorporates a valve with three operating positions.  The first position permits flow through the housing and blocks the outflow (8,9,10), the second position permits throughflow of milk to the intermediate container, outflow (9) and return (10) pipes, while the third position permits milk to flow in addition into a sample container.

Patent DE-3231030-A1 (DE)
Title: Multi-stage hearing aid amplifier
Inventor: EGGERT ALBERT
IPC: H03G3/30
Filed: 1982-08-20
Abstract: A multi-stage hearing aid amplifier is proposed which is intended to exhibit a high resistance to overloading. Based on a hearing aid amplifier having a circuit arrangement for gain control, the hearing aid amplifier according to the invention exhibits a control amplifier (20) operating in class C. This amplifier has two DC-coupled transistors (23, 24) of opposing types of conductivity. The control voltage (UR) output at the output (26) of the control amplifier influences the gain of one or more amplifier stages of the hearing aid amplifier. A hearing aid amplifier in which the control voltage (UR) is supplied to an additional transistor (28), the collector-emitter path of which is connected in series with a capacitor in parallel with the input of a transistor (17) of an amplifier stage (18), is particularly advantageous. <IMAGE>

Title: Contact link arrangement
Inventor: BAERNKLAU KARL DIPL ING
IPC: H01H31/14
Filed: 1982-10-06
Abstract: The invention relates to a contact link arrangement having a U-shaped lead (8) on the fixed contact parts (1, 2). The fixed contact parts (1, 2) have contact facings (3) which can be brought into connection, in the sense of making contact, with the contact facings (6) on the support (5) of the contact link (4). A metal facing (7), which consists of ferromagnetic material but is electrically conductive, is provided on the side of the contact link facing the fixed contact parts (1, 2), between the contact facings (6). The ferromagnetic facing (7) results in an attractive effect between the contact link (4) and the contact parts (1, 2) so that lifting of the contact links in the event of small short-circuits or high starting currents with a relatively low drive force for the contact link arrangement is avoided. <IMAGE>

Title: Solar electrical energy sources SOLEES
Inventor: POISEL OTTO KARL DIPL ING
IPC: H02K44/08
Filed: 1983-08-10
Abstract: The invention relates to solar electrical energy sources SOLEES, which convert solar energy directly into electrical energy by means of the Melk effect and the principle of magneto-hydrodynamic (MHD) generators. A SOLEES cell is composed of the heat receiver (1), which can be rotated in all directions of a hemisphere as a result of a ball bearing, the associated hot heat conductor (2), the conversion system (3) and the positive electron collecting circuit (4), and the negative electron collecting circuit (5). The function of the SOLEES cell is that solar rays are concentrated by means of a bi-convex lens on to the focus spot, and the hot heat plate, which passes the heat on to the hot heat conductor (2) is located at this focus spot. The heat is converted directly into electrical energy in the conversion system (3), by means of the Melk effect and the principle of MHD generators. SOLEES can be brought into use on all heavenly bodies which have no intrinsic heat source and in which no cloud formation occurs. They are outstandingly suitable for space exploration in combination with TERES and MULACES. <IMAGE>

To release the tension-roller chain, the tension piece can be swung away from the basic body of the tension roller, the screw pivoting with its thread part in the tapped hole of the end tension roller about its roller axis.
Patent DE-3340719-A1 (DE)
Inventor: HIEBER KONRAD DR RER NAT
IPC: H01C17/12
Filed: 1983-11-10
Abstract: A method of measuring the electrical resistance of thin metallic films manufactured under the influence of a plasma. The measurement proceeds by means of a direct current resistance measurement according to the principle of a two point or four point measuring method. The electrical resistance is determined either in the case of at least one measuring or test current, and the voltage connected to the measuring contacts is measured when no measuring or test current is sent through the film, or the electrical resistance is determined in the case of at least two different measuring or test currents of known magnitudes. The measuring methods are applied in the case of manufacture of metallic layers in semiconductor technology, in particular also for the measurement of the ion current injected in the film by the plasma as well as for the determination of variations in the coating rate.
Patent DE-3341527-A1 (DE)
Title: Automatically flashing incandescent bulb, without relays
Inventor: ROEMER JUN WALTER
IPC: H01K1/64
Filed: 1983-11-17
Abstract: The incandescent bulb is a conventional bulb, but is modified such that a bimetallic element is installed in the shaft of the same. This design saves the installation of a flashing transmitter relay. The bimetallic element rests in contact, that is to say in the cooled state is aligned such that it bulges inwards, which means that the circuit is closed. If the flasher lever is now operated, a current supply via the bulb socket is ensured which heats the bimetallic device in the bulb, bulges it outwards, interrupts the closed circuit, and the incandescent bulb is no longer illuminated. The bimetallic device now cools and bends back into its original position. The circuit is closed again, and the bulb illuminates again. This process repeats itself until the flasher lever is moved back into the "OFF" position. In order to achieve reliable coincidence of the end of the bimetallic device and the end of the power supply lead, there is a groove at the end of the power supply lead, into which groove the bimetallic device can be inserted during closing.
