Patent DE-3235568-A1 (DE)
Title: Circuit for exposure control in flash guns
Inventor: ACKERMANN KARL
IPC: G03B15/05
Filed: 1982-09-25
Abstract: An electronic flash gun is proposed, which has a device for altering the irradiated quantity of light and which is fed by a generator including a flash capacitor. The flash gun has an integrating capacitor (26), which determines the time of illumination of the flash tube (1, 2) and which is charged up by the voltage drop at a resistor (23) situated in the current circuit of the flash tube (2), after the flash tube has been fired. Since the voltage drop at the resistor proceeds in proportion to the discharge characteristic of the flash capacitor, the gun can be operated with different generators without this resulting in effects on the quantity of light irradiated by the flash tube in each instance. The electronic flash gun is particularly suitable for close-up exposures; in this case, it can procure its power from a second flash gun, which has its own generator part with a connection for a connecting cable. <IMAGE>

Title: Steering and ignition lock for motor vehicles
Inventor: WITTWER REINHARD
IPC: B60R25/021
Filed: 1982-09-30
Abstract: In a steering and ignition lock for motor vehicles, in addition to the lock cylinder, a locking bolt is used which is transversely displaceable in order to block the steering column and can be reset against a resilient expulsion system in an insertion position, which releases the steering column, by an eccentric which can be actuated by the key and is connected fixed in terms of rotation to the lock cylinder. The insertion position is secured by the penetrating lower end of a longitudinal slide which is part of a key withdrawal-preventing device which also has a transverse slide. The longitudinal slide is spring-loaded against the locking bolt and has two axially offset contact points for the transverse slide at its undercut upper end. The transverse slide is arranged in the region of the key hole, is radially displaceable with respect to the lock cylinder and projects into the key channel when the key is withdrawn. It is proposed for a simple and space-saving arrangement that the eccentric be arranged axially non-displaceably with respect to the lock cylinder and be provided with a bearing point which is kept free of spring forces. The locking point between the longitudinal slide and the locking bolt consists of inclined faces and generates an axial force component which is derived from the transversely directed resilient expulsion system of the locking bolt and is used for pushing back the longitudinal slide and transverse slide. The locking bolt also has, in addition to this locking point an [lacuna] pointing in its axial direction ... Original abstract incomplete.

Patent DE-3239305-A1 (DE)
Title: Axial bearing support
Inventor: HOERBURGER RUDOLF ING GRAD
IPC: F16C25/08
Filed: 1982-10-23
Abstract: The axial bearing support has the object of compensating automatically for length differences of machine parts (e.g. a transmission shaft in the housing) moving relative to one another resulting from heating in use or different materials, without significantly altering the axial compression stresses on the bearing and hence its axial clearance thereby. This object is achieved by both such a material composition and by a suitably pressure-resistant design of a supporting ring in a manner known per se, which expands faster and approximately only just as far as the part (e.g. the housing) which expands the most, the supporting ring in the mounted state not significantly yielding to the prescribed axial compression stresses of the bearing. In this way, both excessively hard running and excessive play in the bearing are avoided and the screws and housing cross-sections causing the prestressing are largely destressed. The life of such machines can be greatly improved using these cost-effective means, despite increased loads.
Patent DE-3243604-A1 (DE)
Title: Arrangement for radar signal processing
Inventor: LUDLOFF ALBRECHT DIPL ING
IPC: G01S13/524
Filed: 1982-11-25
Abstract: In a Doppler filter bank with a plurality of Doppler filters, the filter weightings are intended to be designed to be adjustable. Via a means known per se for identifying the echo intensity within a block, and a memory with a resident facility allocating a specific intensity to the mainlobe/sidelobe separation of the Doppler filters, the filter weighting coefficients are adjusted in such a way that the mainlobe/sidelobe separation in the case of low echo intensity (global or local) is less than in the case of high echo intensity.

Title: Process for the crosslinking of chemical substances under the action of heat in a closed mould
Inventor: ROETHEMEYER FRITZ DIPL ING DR
IPC: C08J3/24
Filed: 1983-01-25
Abstract: The vulcanisation of rubber articles and similar crosslinking processes take place according to predetermined time/temperature programmes. In order to maintain the desired degree of crosslinking to a closest possible approximation against the changing effects of external disturbance factors, it is necessary to control the time period in accordance with critical temperature for each article. The invention avoids the difficulties associated with direct measurement of the temperature at the article itself by measuring the temperature of the mould wall in the vicinity of the article in an easily accessible area and then calculating with the aid of a microprocessor the appropriate temperature for the crosslinking process at the coldest point of the article.

Patent DE-3309305-A1 (DE)
Title: Screw mechanism with screw and threaded rolling-contact nut
IPC: F16H25/22
Filed: 1983-03-16
Abstract: In a screw mechanism with a screw and a threaded rolling-contact nut, the threaded rolling-contact nut and the screw thread have the same pitch and the centre axis of rotation of the threaded rolling-contact nut is offset parallel to the longitudinal axis of the screw. For a screw mechanism of this type, the invention intends to provide low-friction guidance between the nut and the screw, in order to maintain the centre distances, and to ensure power transmission free from jamming. For this purpose, two guiding threaded rolling-contact nuts are provided in addition to the driving threaded rolling-contact nuts and these guiding nuts are each arranged with a limited range of axial free movement relative to the driving nut. The distance between the longitudinal axis of the screw and the centre axis of rotation is adjustable using adjusting means, preferably flexible adjusting means, and the said axes do not move in a planetary manner around one another but are fixed in position. The screw runs in a manner similar to a planet wheel on an internal toothing. The screw is driven. By this means, frictionless guidance is achieved and jamming, which may arise due to differing travels of the various nuts, is avoided.

Title: Excitation circuit for laser systems, especially for TE high-energy lasers, with adjustment of the pre-ionisation
Inventor: CIRKEL HANS-JUERGEN DR
IPC: H01S3/0971
Filed: 1983-04-19
Abstract: In order to control the time at which the laser gas discharge is used, the time relationship between the application of the high-voltage pulse to the laser electrodes (EL) on the one hand, and the application of the triggering pulse to the poles of the pre-ionisation devices, on the other hand, can be controlled in the excitation circuit. This is done by variable connection of the high-voltage supply for the auxiliary circuit of the pre-ionisation device to at least one of three different circuit points (A, A* or A') of the pulse-forming network (PFN 1), of which the one circuit point (A) at the input of the pulse-forming network on the high-voltage side, the second circuit point (A*) at the high junction point of the high-voltage switch (SL) and of the one strip line capacitor (CF), and the third circuit point (A') are connected directly to the supply lead of the high laser electrode (EL). At the same time, the earth lead of the auxiliary circuit is connected to the earth potential rail (B) of the pulse-forming network (PFN 1). <IMAGE>

Title: Tubular door closer, especially for swing-to doors
Inventor: BENECKE OTTO
IPC: E05F3/22
Filed: 1983-06-27
Abstract: The tubular door closer, despite a weak spring and an associated low opening force, is to retain the door securely in the closed position and, furthermore, be capable of overcoming closing resistances in the form of lock latches and of preventing a self-opening of the door by the action of wind. This is achieved in that the closer rod located in the closer tube has an annular groove and/or an end thickening, into which an elastic annular gasket fastened in the closer tube engages with a gasket lip or engages behind an end thickening respectively.

Title: Double bogie for rail vehicles
Inventor: FREDERICH FRITZ PROF DR ING
IPC: B61F3/16
Filed: 1983-11-28
Abstract: In order to reduce the high degree of wear of the wheels and of the rails occurring in the bogies of rail vehicles, in particular in tight bends in the track, and to reduce the associated noise nuisance and the high consumption of energy, a bogie is proposed which aligns its longitudinal bogie axis by rotating or swivelling under the wagon body tangentially with respect to the centre of the track of the respective bend in the track which is being travelled through whilst the individual wheels, which are coupled to one another in pairs, can align themselves with the plane of the wheels tangentially with respect to the rails being used by them. As a result, the wheels run around the bend in an almost ideal fashion with minimum steering angle with respect to the bogie frame. Depending on the application, different embodiments of the bogie described which are however based on the same principle can prove particularly expedient.

Title: Integrated process for the production of less active metals and of hydrocarbons using non-stoichiometric sulphides or oxides of potassium
Inventor: SWANSON ROLLAN
IPC: C07C1/26
Filed: 1984-01-13
Abstract: The invention relates to a chemical process for the production of elemental potassium and subsequent reaction of the elemental potassium with other reactants, including various metal ores, such as those of magnesium, lead, copper, zinc, arsenic, antimony or silver, in order to liberate these metals in the elemental state from their naturally occurring forms. However, the elemental potassium can also be reacted with water in order to prepare potassium hydroxide and hydrogen, further elemental potassium being reacted with the potassium hydroxide in order to prepare more hydrogen and a thermally unstable potassium oxide which decomposes to form potassium and potassium peroxide or potassium superoxide. Said hydrogen and said potassium can also, if desired, be reacted with one another in order to prepare potassium hydride in order to store the hydrogen generated in this way, or the potassium hydride can be further reacted with carbon to prepare potassium acetylide, and further hydrogen may, if desired, be used to saturate the carbon bonds of these unsaturated compounds, the potassium or potassium hydride obtained from the process being used to catalyse the hydrogenation.
