Patent DE-3228952-A1 (DE)
Title: Hot water boiler flange
Inventor: WAWROVSKY RUDOLF
IPC: F24H1/18
Filed: 1982-08-03
Abstract: In the flange structures known hitherto it was disadvantageous that, due to the flattening of the curved end in the region of the circular opening to the boiler interior, there was a corner in which excess enamel collected which had not flowed out. The object of the invention is to provide a hot water boiler with a flange which has no accumulations of enamel in the region of the boiler floor when the boiler is vertically mounted. The curved end (1) has a circular opening (2). The flange (3), which is angular in cross-section, is welded at its inner edge (4) of the inner circle with a hollow weld (5) to the curved end (1) of the boiler. A rounded transition is thus obtained from the boiler interior to the inner circular surface of the flange (3). The boiler is internally enamelled, the enamel layer being flowless due to the rounded transition and reaching up to the outer edge (7) of the inner circle of the flange (3). Furthermore, the flange (3) is welded with a second weld seam (8), in this case with a V-weld, to the outer side of the curved end (1). In addition, eight threaded bolts (9) are screwed in at the periphery of the flange and serve for fastening the boiler cover (not shown) with nuts. <IMAGE>

Patent DE-3244798-A1 (DE)
Title: Cable guide on a frame which can pivot
Inventor: PATSCHECK MAX
IPC: H02B1/20
Filed: 1982-12-03
Abstract: The invention relates to a cable guide on a frame which can pivot in cabinets for holding electrical structural units, especially computer cabinets for data processing. In this case, the problem arises that the cables are subject to bending stress as a result of the pivoting out of the frame, which can result in wire fracture or the insulation chafing through. In order to avoid this disadvantage, the invention provides for at least one cable holder (2) to be mounted on the pivoting frame (1) such that its free end lies directly on the imaginary pivoting axis and for a cable tie (3) to be supported rotatably with the free end of the cable holder (2) at the point passing through the imaginary pivoting axis. The guided cables (4) are mounted on the cable holder (2) by means of this cable tie (3). <IMAGE>

Patent DE-3248209-A1 (DE)
Title: Device for ejecting cartridges
IPC: F41A15/08
Filed: 1982-12-27
Abstract: The extractor (20) is driven via a spring (14) which is stressed for the ejection process. If the cartridge can move easily in the firing chamber, a slight stress is sufficient to push the cartridge out. A fired cartridge (23) which is sticking slightly in the firing chamber leads to the spring (14) being compressed more strongly, however, so that the fired cartridge is finally ejected. At the end of the spring movement, direct, unsprung pushing out and subsequent ejection are also possible. <IMAGE>

Patent DE-3303547-A1 (DE)
Title: Wind power unit
Inventor: GROELICH KARL
IPC: F03D5/02
Filed: 1983-02-03
Abstract: The wind power unit constructed in accordance with the invention represents a variant for obtaining energy by comparison with the known wind motors and wind wheels. The wind power unit consists essentially of wire ropes which run over rope pulleys. Sails are mounted between the wire ropes in a manner distributed thereupon. The wind power unit is situated in the direction of wind in an inclined plane, or at an angle to the direction of wind in a horizontal plane. The resulting forces from the wind pressure on the sails and from the suction behind the sails drive the latter forwards. This causes the rope pulleys to execute a rotary movement which is used to drive generators and pumps. The wind power unit runs with the supporting structure in a bogey, preferably on a circular rail, in a manner rotatable in all directions. A servomotor is used to rotate the wind power unit into the respective favourable lifting wind direction.

Title: Method for controlling the articulation stability of road vehicles having at least two vehicle parts which are connected by an articulation unit and an articulation unit for carrying out the method
Inventor: GRASSMUCK JUERGEN
IPC: B62D47/02
Filed: 1983-07-28
Abstract: The invention relates to a method for controlling the articulation stability of road vehicles having at least two vehicle parts which are connected by means of a joint and can be in a stationary, non-stationary, stable or unstable driving state and an articulation unit with a joint which can be actuated by means of hydraulic actuation means and a hydraulic control device which can be actuated by means of an electronic processor and has stop valves arranged in the hydraulic circuit and at least one damping valve. For the steering angles possible in a stable driving state, the respectively associated articulation angle is initially determined and then in travelling mode it is tested in a repetitive manner after a predetermined route in each case whether the articulation angle predetermined at the start of the route as a function of the respective steering angle corresponds to the articulation angle actually present at the end of the route and then in the event of a deviation of the respective actual value of the articulation angle from the reference value of the change in the articulation angle the joint is adjusted until the actual value of the articulation angle corresponds to the reference value of the articulation angle taking into account the admissible tolerance range. In the articulation unit, the actuation means are constructed as hydraulically double-acting cylinders (36, 37) and the electronic control device (31) has a microprocessor (33) or a microprocessor circuit which is in an operative connection with a non-volatile memory (32) for storing the characteristic diagram  DELTA  beta =f( beta , alpha ) where beta equals the articulation angle,  alpha  is the steering angle and  DELTA  beta  is the change in the articulation angle  beta after a route  DELTA s for a specific steering angle  alpha  at the start of the route. The microprocessor (33) or the microprocessor circuit is clocked by means of a frequency generator at a frequency corresponding to a multiple of the displacement pulse  DELTA s. <IMAGE>

Title: Electronic circuit for operating a safety device
Inventor: KANPPMANN ROLF DIPL ING
IPC: H02H3/04
Filed: 1983-11-09
Abstract: The invention relates to an electronic circuit for operating a safety device for systems having parts which move freely in three-dimensions, especially for industrial robots. Such a safety device is described in European Patent Specification EU-PS 0012383. The circuit receives electrical voltages which are applied to switching means, as input signals, and emits output signals to a control device which stops the moving parts or initiates an emergency-running program. The voltage UF applied to the switching means divides window discriminators into voltage ranges U1, U2, U3, U4. The window formed by the voltage ranges U3, U4 is smaller than the window formed by the voltage ranges U1, U2. The windows defined by the voltage ranges can be adjusted independently of one another. Output signals are emitted when the voltage UF is within [sic] the voltage U1 or above the voltage U4. In order to increase the reliability, a further window discriminator can be provided in such a manner that the circuit remains serviceable in the event of failure of one window discriminator. The position of the voltage UF within the window discriminators can be indicated by light-emitting diodes. <IMAGE>
