Title: Circuit arrangement for electronically locking and unlocking safety systems
Inventor: ARNOLD KARLHEINZ
IPC: B60R25/10
Filed: 1983-07-11
Abstract: A circuit arrangement for electronically locking and unlocking safety systems, preferably on motor vehicles, is proposed which responds to a particular pulse sequence output by a transmitter arranged outside the object to be protected to a receiver arranged within the object and which is intended to prevent a decoding of the pulse sequence during the locking and unlocking of the safety system by means of monitoring devices. For this purpose, the receiver (15) is coupled by a switching device (13) to an interference transmitter (16) in such a manner that the interference transmitter (16), which is not shielded towards the receiver (15), outputs interference pulses in dependence on the pulse sequence of the signal transmitter (14) received at the receiver (15), which pulses partly overlap the received pulses of the signal transmitter (14) in time. Such a circuit arrangement can be used for protecting closed spaces by locking and unlocking locking members and for monitoring objects by arming and disarming alarm systems. <IMAGE>
Patent DE-3327121-A1 (DE)
Inventor: DRECHSLER KLAUS DIETER ING GRA
IPC: G11B23/00
Filed: 1983-07-27
Abstract: Strict care must be taken in the mass production of high packing density, disc-shaped information carriers such as represented, for example, by the manufacture of compact discs, that no mix-ups occur of workpieces having different informational content during the production sequence. Proceeding on the basis that disc magazines are employed for conveying the disc-shaped workpieces from work station to the next, it is proposed that the disc magazines have a processing sequence for the workpiece stack they contain which is rigidly defined for all work stations by means of fitting parts. Also, each workpiece stack and thus each disc magazine accepting a workpiece stack therein is accompanied by an identifier disc whose shape corresponds to the shape of a workpiece. The identifier disc thus assumes the initial position in the rigidly defined hierarchy of a workpiece stack within a disc magazine. This identifier disc is read first at an input side of a work station by means of a read unit before the working-off of the workpiece stack contained in the disc magazine is undertaken in the prescribed sequence.

Title: Combustion engine with steam generating system
Inventor: WIESER RUDOLF DR
IPC: F02B3/06
Filed: 1983-09-14
Abstract: The production of steam by the exhaust gases from combustion engines and use of this steam to generate mechanical or electrical energy is already known. The proposal according to the invention is now directed towards generating steam not only by means of the engine exhaust gas heat but also by means of the engine cooling heat and thereby achieving an additional fuel saving. Two steam generators with different operating pressures are provided. At the same time during operation the heat exchanger surfaces of the steam generator are heated at higher operating pressure partly by the heat transfer fluid of the engine cooling system and partly by the exhaust gas of the engine. For the cylinder liners a thin-walled design with external cooling ribs is proposed, which is pressed into an enclosing metal cylinder. Working steam at a pressure of approximately 20 bar can thereby be generated using the engine cooling heat. The total efficiency of a conventional diesel engine, which is normally about 40%, can be increased to over 50% by the proposed steam generating system. <IMAGE>

Title: Magnesium-containing cast iron material and article, produced therefrom, having a cementite chill layer
Inventor: NONOYAMA HIDEO
IPC: C22C37/10
Filed: 1983-11-10
Abstract: A cast iron material has a C.E. value of about 4.3 or less and an Mg content from about 0.002% to 0.080%. The Mg content is suitably greater than about 0.006% and preferably greater than about 0.011%, in order to prevent the occurrence of gas bubbles in the surface of an article produced with the use of this material. Moreover, the Mg content is suitably less than about 0.060% and preferably less than 0.040%, in order to ensure good flowability of the material during casting. An article produced from a cast iron material of this type has a surface region which consists of a chill layer consisting for the major part of cementite, and this surface region can be produced by heating and melting a surface region of the article by means of a high-performance energy source and then rapidly cooling this surface region.

Title: Method for a safety system for reducing the risk of accident as a result of the speeding of motor vehicles and motorcycles
Inventor: OVERSOHL WILHELM DIPL CHEM DR
IPC: B60Q1/54
Filed: 1984-01-10
Abstract: In the patent application P 3329783.5, a safety system is described which consists in speed ranges with different maximum speeds such as, for example, 50 km/h for in-town motoring and 100 km/h for trunk roads being preset via controllers and the maximum speed associated with the particular range being prevented from being exceeded via the controller and the speed range in which the vehicle is travelling being indicated by means of a conspicuous sign which can be seen from the outside. According to P 3329783.5, the speed ranges are switched on manually. The development of the safety system in the supplementary patent application consists in the fact that speed ranges can be switched on by radio signals which are transmitted by mobile or permanently installed transmitters ahead of hazards. The motor vehicles have receivers tuned to the said transmitters, via which receivers radio signals are received and converted into switching pulses for the controller circuit. As a result, travel speeds can be matched to travel conditions such as, for example, fog, ice, restrictions of the carriageway, road repairs, occurring at a specific time and place, and to the existing hazards. The speed ranges entered via radio signals delete the previously manually entered range and remain effective until a further radio signal clears the speed ranges again for manual setting.

Patent DE-3401863-A1 (DE)
Inventor: MAIER GERHARD
IPC: H03D/
Filed: 1984-01-20
Abstract: A mixer circuit with a conventional very high frequency circuit for the reception of color television bands I and III, which is connected dependent on the band and which is provided with an NPN transistor. The NPN transistor operates via a collector resistor onto a two circuit band filter. Moiré interferences in the band I region expanded for CATV are avoided by having the mixer current used to 0.3 to 0.6 mA via a counter coupling resistor disposed between base and hot end of the resistor 4. Thus the self-interference in band I is reduced by a value of about 60 dB. In case of band III operation the corresponding switching voltage is fed via a series connection of a diode 6 and a resistor 5 to the base and thus the base level is lifted up to higher mixing current, since in band III self-interferences cannot occur in the case of the presence of signals.

Title: Control key with rotating drive
Inventor: BENESCH HELMUT
IPC: G05G5/06
Filed: 1984-04-04
Abstract: The control key converts the pivoting movements of the handle (5) to the left or right into a straight-lined movement of the pressure plunger which consists of two pairs of half shells (30, 31 and 32, 33 respectively) which can be replaced depending on the desired function, in that a cam operates the half shells (30, 31 and 32, 33 respectively) against the pressure of a spring (4) via curves (40, 40', 42, 42' and 43, 43', 45, 45' respectively) which are located at the junction point of the half shells (30, 31 and 32, 33 respectively). A pair of half shells can be rotated through 180 DEG  in the control key so that another curve is in each case engaged with the cam (10). The use of two pairs of half shells (30, 31 and 32, 33 respectively) enables the following functions of the key as a result of this programming capability:   a) latching both in the right-hand and in the left-hand limit position;   b) latching only in the right-hand limit position;   c) latching only in the left-hand limit position; d) the key pivots back both from the right-hand and from the left-hand limit position into the original position.   <IMAGE>

Patent DE-3425166-A1 (DE)
Title: Endoscope
Inventor: SCHOELLY WERNER
IPC: A61B1/00
Filed: 1984-07-09
Abstract: For the purpose of image transmission, an endoscope with an eyepiece and a probe part has an optical system with an eyepiece and an exchangeable lens. Optical fibres which can be connected to a light source serve the purpose of light transmission. In the path of the image and light transmission, the endoscope according to the invention has one or more disconnectors (9) whose connections have coaxial, mutually matching optical slip rings (12) for the light transmission as well as a central image transmission. Owing to this construction, it is possible, at least in the disconnector region, for the mutually coupled endoscope parts to be rotated with respect to one another about their longitudinal axis without an impairment of the image and light transmission occurring in the process. In the case of the connection of interchangeable lenses (15) by means of a screw connection, there is therefore no need for any special measures in order precisely to maintain a specific rotary position relative to one another. Moreover, by appropriate construction of the disconnector it is also possible to mount endoscope parts to be rotatable in any way on the basic endoscope instrument. <IMAGE>

Title: Distance profile for frameless glazing
IPC: E06B3/663
Filed: 1984-07-12
Abstract: To avoid three-sided adhesion of a sealing compound (14) made of silicone rubber, with which a fastening and sealing of a glazing (12) is carried out on a façade element (10), the region (22) of a distance profile (16) adjacent to the seal is designed in such a manner that no significant forces are transmitted from the distance profile (16) to or into the seal (14) and vice versa. This region can consist of a separating foil (22) which is anchored on the body of the distance profile (16) and which ensures that an adhesion between seal (14) and distance profile (16) is excluded. The region of the distance profile adjacent to the sealing compound can, however, by selecting a suitable geometrical design or a suitable material, be made "soft" in such a manner that a transmission of significant forces between sealing compound and distance profile is excluded. <IMAGE>
