Title: Frequency-stable gas laser
Inventor: HEYNISCH HINRICH DIPL PHYS DR
IPC: H01S3/03
Filed: 1983-07-26
Abstract: The proposed gas laser has the following construction: the resonator mirrors (1, 2) are supported by an elongated hollow body (3) which consists of a material having a thermal coefficient of expansion alpha 1 < 5 x 10<-7 DEG >K<-1>. The complete resonator unit is supported in a sprung manner in a vacuum sleeve having an  alpha 2 > 30 x 10<-7 DEG >K<-1>. Electrodes (5, 6) are passed through the sleeve, which electrodes approach one another in the gas space outside the resonator in such a manner that - in accordance with Paschen's Law - the gas discharge always takes the detour through the mirror body. In a preferred exemplary embodiment, the electrodes (5, 6) contain pins (17, 18) which in each case project into a side opening (10, 11) of the hollow body (3) and are connected to a metal strip (19, 20), which points toward the opposing electrode, on the inner wall of the sleeve. <IMAGE>

Patent DE-3333054-A1 (DE)
Title: Burner
IPC: F23D99/00
Filed: 1983-09-14
Abstract: The invention relates to a burner for a fuel-air mixture in a flat jet embodiment. The mixing chamber is for this purpose of approximately triangular shape and has a flow cross-section which widens out like a fan in the outlet direction. The mixing chamber is provided in the neighbourhood of its outlet opening with a rod which runs parallel to its outlet longitudinal direction and is especially a threaded rod. A profiling of the emergent flow is thus produced between the rod and the longitudinal walls, with the formation of channels which facilitate the formation of a comb-like flame. This flame is very stable and not only prevents flash-back in normal operation but also is only slightly susceptible to failure by the action of false flows such as can arise on rapid movements of the burner.

Title: Circuit arrangement for the decentralised controlling of access to a common data and control bus
Inventor: HAGMEISTER THOMAS DIPL ING
IPC: G06F13/37
Filed: 1983-10-01
Abstract: A circuit arrangement for the decentralised controlling of access to a common bus of a multi-processor system (bus allocation logic) is connected ahead of each processor unit sharing the bus. The signals (HOLD, HLDA) necessary for controlling bus access are brought together via the circuit arrangement in a loop line. The bus allocation logic has two clocked intermediate memories (4, 5), which are controlled by means of a decision logic (12). The bus-enable signal (HLDA) is switched to the data input (10) of the first intermediate memory (4) and, in dependence on the decision logic (12) and the system clock (8), is passed on as bus-enable signal (HLDA) for the next processor unit via the data output (13). In the case of an internal bus request (HOLD-INT) of the processor unit at the data input (11), the bus is held by the bus request signal (HOLD) in dependence on the decision logic (12) and the inverted system clock (8). <IMAGE>

Patent DE-3405582-A1 (DE)
Title: Process for the preparation of N-substituted ureas
Inventor: BESENYEI GABOR
IPC: C07C273/18
Filed: 1984-02-16
Abstract: The invention relates to a process for the preparation of N-substituted ureas by reacting carbon oxide, water and nitro compounds, or by reacting carbon oxide, nitro compounds and amines, in the presence of organic and/or inorganic selenium compounds with catalytically active selenium and in the presence of water and/or bases, in which process the catalytically active form of the selenium is prepared from selenium-containing compounds by physical, chemical or photochemical means before or during the carbonylation reaction. The selenium compounds used as catalysts for this process are stable under normal conditions and can be converted into the catalytically active form by a suitable activation process. The use of the selenium compounds which have previously been employed as catalysts of the carbonylation reaction and which cause handling problems can therefore be avoided according to the invention. The N-substituted ureas prepared by the above process are mainly used in the crop protection chemicals industry.

Patent DE-3407961-A1 (DE)
Title: Device having at least one electrical machine
Inventor: SCHULLER GUSTAV
IPC: H02K7/06
Filed: 1984-03-03
Abstract: The electrical machine, which is constructed as a motor or generator, has a rotor which is supported within a stator such that it can rotate about a rotation axis (rotating shaft). The rotor is provided with an axially continuous shaft hole which is coaxial with respect to the rotation axis. This shaft hole is used for accommodating a shaft body about which the rotor can rotate, so that this shaft body can be used to allow the electrical machine to be used in a space-saving manner for very different purposes, for example as a stationary tube for cables to be passed through, or as a stationary shaft for supporting the electrical machine. The shaft body can also be connected to the rotor by means of a drive (transmission), for example a thread or a cam guide, so that the shaft body carries out a translational movement during the rotation of the rotor, which translational movement can be used for feeding, switching, pumping or the like.

Patent DE-3416343-A1 (DE)
Title: Bearing inspection device
Inventor: AUCHTER BRUNO DIPL ING
IPC: G01M13/04
Filed: 1984-05-03
Abstract: The invention relates to an inspection device for continuous monitoring of the wear in the bearing area of shafts, especially of pump shafts. A problem here is the inspection of wear, especially inspection of the bearing, by means of which continuous wear monitoring and the indication of impending damage is made possible. Damage is to be calculable in good time with a view to the stocking of material and the allocation of personnel. The repair times and hence the repair costs are to be minimised. The problems are resolved by the invention in that at least one measuring sensor is arranged at a certain distance from the shaft sleeve. The measuring sensor makes contact in the proposed contact area, provided that the shaft with the shaft sleeve fixed on it exceeds the proposed bearing clearance.

Title: Erection crane having a device for doubling the lift of a fork-lift truck lift
Inventor: SCHALL SIEGFRIED
IPC: B66F9/06
Filed: 1984-07-21
Abstract: The invention is used only in conjunction with a fork-lift truck. By means of this apparatus, the fork-lift truck becomes a crane vehicle. It is thus possible to lift loads, especially supports and individual parts for halls and industrial installations, twice as high as with the fork-lift truck on its own. It consists essentially of a base frame (I) and crossbeam (II), as well as a load cable (10). The base frame is connected to the load holding means of the fork-lift truck. The T-shaped crossbeam (II) is inserted into it like a telescope. Said crossbeam has two deflection rollers (9) over which the load cable (10) runs in a moving manner. The load cable is firmly connected to the lifting frame (13) of the fork-lift truck. In consequence, the lifting height (H) of the load holding means is doubled. By telescoping the crossbeam (II) in the base frame (I), height is once again gained, but in this case the lift remains unchanged. This is of advantage for erections.

Title: Warping machine
Inventor: ITEN JAKOB
IPC: D02H13/10
Filed: 1984-09-01
Abstract: The drive unit (4) of a beaming device with a warp beam (40) is controlled by a control unit (4') which generates control signals for driving the warping drum (2) for the warping of individual warp sections and for the common beaming of all the warp sections onto the warp beam (40), for crawling speed during the beaming phase and for stopping the machine. A signal generator (51) serves for keying a signal corresponding to a yarn break occurring into a computer (50) which, in response to this signal, records the instantaneous warp-yarn length and the warp-section number or position in the form of a signal generated by switching means and by a preset warp-section number indicator (53), which computer (50) further sorts the recorded yarn breaks in a sequence corresponding to the beaming operation and, moreover, via a comparator stage (56), compares the length signals corresponding to the sorted yarn-break points with the signals of the switching means (52, 54) determining the warp-yarn length, an identity signal fed to the control unit (4') from the comparator stage (56) causing at least one control signal which influences the drive unit (4) of the warping drum (2) in order to eliminate the yarn break. <IMAGE>
Patent DE-3434417-A1 (DE)
Title: Contact arrangement for vacuum switches
Inventor: RENZ ROMAN DIPL PHYS DR
IPC: H01H33/664
Filed: 1984-09-19
Abstract: In a contact arrangement for vacuum switches having pot contacts, the arc is intended to be held on the annular contact surfaces (17) of the pot contacts. It is known for this purpose to provide an annular region of relatively low electrical conductivity underneath the contact surface in the interior of the contact, around which the current flowing in the contact essentially flows so that it produces magnetic fields which are intended to hold the arc on the bearing surface. This effect is achieved in a considerably better and more reliable manner in that a concentric zone (7) of relatively low conductivity is arranged in an adjacent manner on the annular region (27), which zone (7) is narrower than the existing annular region (27) of relatively low conductivity in the contact and extends into the contact surface (17). The invention is particularly suitable for vacuum switches having high short-circuit switching-off currents. <IMAGE>
Patent DE-3437030-A1 (DE)
Inventor: MEISTER KLAUS DR
IPC: E05B49/02
Filed: 1984-10-09
Abstract: A locking system includes a key which has a carrier provided with coded information. The coded information is obtained from an insulating layer containing a plurality of windows in which conductive strips extend. Each window is traversed by at least one conductive strip which is electrically connected to the carrier and with at least another strip which is insulated therefrom. Applying onto the windows is a coating layer which selectively insulates each window by either insulating the one strip or the other strip or the entire window so that each window can be coded by either one of three information modes. Cooperating with the key is a reader which contains reading contacts, a potential supply contact and different types of code contacts arranged in an arbitrary manner and communicates with electrical circuitry to determine the correctness of the key.
Patent DE-3437867-A1 (DE)
Inventor: JACOB GERNOT
IPC: A47L9/00
Filed: 1984-10-16
Abstract: A vacuum cleaner housing possesses two guide means on the inner side of the end housing wall with a suction port therein in order to receive the board flange of a dust bag adjacent to the lateral housing wall. The guide means comprise guide rails each with a ramp-like wall, extending towards said housing wall, and guide ribs which are located in the lower part of the housing wall and have a slope opposite to that of the ramp-like walls. They are so shaped as to allow the board flange to be inserted between them and the walls. On introduction of such a board flange of a dust bag its lower end section is bent along a prepared line of bending, which has been formed in the lower part of the board flange parallel to its lower side. Accordingly the board flange is so firmly held in place that it is not bent by the suction force to which it is exposed. The vacuum cleaner housing is further made with a cover stop which prevents closure of the cover unless a dust bag has been previously placed in the vacuum cleaner housing.

Title: Wind protection mattress
Inventor: SOMMER RUDOLF
IPC: A47C27/08
Filed: 1984-11-03
Abstract: A completely novel way of lying in the open air is made possible by the invention, which is intended chiefly for camping and other leisure activities. A specially shaped enclosure round an inflatable lying surface provides adjustable protection from the wind and concealment. A sluice effect is produced when the mattress is used on water by means of windows which can be covered (from the lying side), so that water can immediately penetrate when the wind protection mattress is overloaded, thus alerting the user(s) of the fact that it is overloaded before an accident can happen (to non-swimmers). <IMAGE>
