IPC: F21L4/08
Filed: 1981-05-12
Abstract: A portable hand lamp (10) is inserted in a charging unit (12). The charging unit embraces the lower part of the hand lamp (10) and holds it firmly. Provided on the side walls of the opening (20) in the charging unit (12), which embraces the hand lamp (10), for the purpose of quicker removal of the hand lamp from the charging unit and for the purpose of better guidance are resilient contact rails (40, 41, 42) which guide the hand lamp and come to be guided in electrical contact by means of contact pieces (50) on the hand lamp. In this arrangement, the hand lamp is held firmly on the charging unit (4) by means of permanent magnets (38). <IMAGE>

Title: Method and circuit arrangement for monitoring the transmission of information between a higher-order digital device and a lower-order digital device
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04L5/16
Filed: 1981-06-05
Abstract: The invention relates to a method for monitoring the transmission of information between a higher-order digital device and a lower-order digital device via a two-wire line according to the time division method, a transmission pause being maintained in both types of device in each case between time spans in which transmit or receive mode prevails. For this purpose, the time spans for the transmission pauses which are maintained in order to allow for signal errors produced by reflections are monitored according to the invention during a partial period, in which reflections of this type are no longer to be expected, in order to detect the occurrence of information signals, which can only be the result of errors in the transmission of information.

Title: Contact element for pressing into printed-circuit boards
Inventor: BRAUER WOLFGANG
IPC: H01R12/58
Filed: 1981-06-29
Abstract: For a contact element for pressing into metallised holes in a printed-circuit board, it is provided that this contact element is produced from a sheet-metal material of uniform original thickness, the pressing-in region (4) being shaped by bending the sheet-metal material in a V- U- Y- or Z-shape about the longitudinal axis (13). In this case, in order to prevent the limbs (7) of this pressing-in region springing, and thus in order to achieve sufficient, permanent edge compression of the pressing-in region in the printed-circuit board hole, it is provided that the interior (8), which is bounded by the limbs (7), be filled with solder compound (9). <IMAGE>

Title: Shrinkage device for the shrinking-in of piece goods surrounded by shrink foil
Inventor: SCHWANK BERND
IPC: B65B53/06
Filed: 1981-09-15
Abstract: In shrinkage devices for the shrinking-in of piece goods surrounded by a shrink foil, especially of large-volume piece goods located on a pallet, an arm is centrally mounted above the respective piece goods so as to be rotatable about a vertical axis of rotation in a machine frame. A hot-gas device is arranged displaceably on the arm, and connected to the hot-gas device is a blower for blowing out the hot gas in the direction of the piece goods to be shrunk in. The combustion of the fuels takes place in the hot-gas device. Moreover, the hot-gas device can be moved only on cylindrical tracks. In order to obtain maximum fire protection and allow adaptation to the shape of the piece goods to be shrunk in, it is proposed to arrange a combustion chamber in a stationary manner on the machine frame, and to connect thereto a channel leading to a blowing-out nozzle which, during the rotation, can be displaced in the manner adapted to the circumferential contours of the piece goods, the blower being downstream of the combustion chamber.

Patent DE-3145188-A1 (DE)
Title: Rotary piston engine
Inventor: MOK WEI
IPC: F02B53/08
Filed: 1981-11-13
Abstract: The invention provides an engine with a high thermal efficiency which operates with auxiliary rotary piston pumps in order to ensure that for ignition sufficiently pressurised fuel/air mixture is forced into the interspaces of the rotary element in order to produce high-pressure expansion gases, which are guided symmetrically at least through one pair of obliquely extending longitudinal channels of appropriate cross-section in such a way that they cause sealed vanes of the rotary element to rotate and produce maximum power. Cooling water jackets are used as steam boilers in order to convert heat stemming from the cooling process into steam and pass it through a non-return valve into the longitudinal channels in order to increase engine power. Exhaust gases are used to drive a centrifugal pump in order to perform the first stage of fuel/air compression. Approximately 2 DIVIDED 3 of the heat energy is converted into work. The structure is simple but performs complex functions. Suitable fuels are petrol and diesel. The rotary piston engine according to the invention has a smooth torque characteristic and can be used to replace the renowned Wankel engine. <IMAGE>

Abstract: A sound generating device for a jogger has a generator circuit for generating pace signals the frequencies of which are different from each other in correspondence with different tempos and for generating reference clock pulses, a time counter for receiving and counting the reference clock pulses, and circuits for selectively supplying pace signals the frequencies of which are different from each other and which are supplied from the generator circuit. In response to an instruction signal generated by a switching operation, the time counter starts counting. Simultaneously, based on a selected pace signal from the generator circuit, a desired pace sound can be produced.

Title: Process and device for increasing the flexural strength of extruded products from mixtures of vegetable particles and binders
Inventor: HEGGENSTALLER ANTON
IPC: B29C48/475
Filed: 1982-06-11
Abstract: The invention relates to processes and devices for increasing the flexural strength of extruded products (4) of mixtures of vegetable particles and binders. During normal extrusion with the aid of a horizontally oscillating ram (1), which compacts the mixture whilst forcing it through a moulding channel (2) and through an adjoining heated curing channel (10), groove-forming indentations (7) are impressed in the extrudate (4) before it enters the curing channel (10) along its surface lines and vertically to the direction of feed of the extrudate (4) during the return stroke of the ram (1). The start-region of the curing channel (10) is adapted to these indentation grooves, so that shape-stabilisation and consolidation of the extrudate occur through the contraction effect of the curing channel (10) as a reaction to the swelling tendency of the extrudate (4). <IMAGE>

Title: Rotary-tube coal gasification plant with introduction of tar in order to suppress the entrainment of coal dust in the gas
Inventor: PETIT PETER JOSEPH
IPC: C10J3/06
Filed: 1982-11-02
Abstract: An apparatus is described which reduces the entrainment of fine particles of coal of normal fuel by tar-containing gases which are produced in a rotary kiln upon the gasification of coal or other carbonaceous material. The fine particles and the tar are removed from the gas and separated from each other. The separated fine particles are introduced into the plant again by mixing and agitating them with newly fed carbonaceous material and recovered tar in a screw conveyor before the said mixture is introduced into the rotary-tube kiln. By the mixing and agitating in the conveyor, the tar coats particles of the newly fed fuel and the fine particles adhere to the tar-covered particles to form a coherent agglomerate. These agglomerates are introduced by the conveyor into the tube kiln and travel a greater distance within the kiln from the gas outlet than in the case of discrete fine particles. In this way, the probability of fine particles attached to the tar-coated particles being removed by the stream of gas from the kiln before the gasification is reduced.
