Title: Front or rear loader with hydraulic implement actuation
IPC: E02F3/43
Filed: 1985-11-23
Abstract: The invention relates to a front or rear loader with hydraulic implement actuation, where an implement/tool, such as a bucket or the like, which can be tilted by at least one double-acting hydraulic cylinder (so-called implement cylinder 2), is articulated on a link vertically movable by means of two hydraulic cylinders (1/1'). According to the invention, this loader is provided with a device which can be selectively switched on for returning the implement from an emptying position into a zero/scraping position. Here, a hydraulic line (cylinder-system connecting line) (8), which can be blocked by an electromagnetically operable valve (7) and is switched to through-flow when the automatic implement return is switched on, is arranged between a hydraulic line (5), leading to the chamber or chambers (2a), responsible for the implement return, of the implement cylinder or each implement cylinder (2), and a hydraulic line (6) leading to the piston-side pressure chambers (1a) of the link cylinder (1/1'). A switch (11) which can be operated selectively for switching on the automatic implement return into the zero position as well as a switch (12) which switches off automatically as a function of the implement-cylinder position when the implement zero position is reached are arranged in the electric circuit (10) of the electromagnet (9). <IMAGE>
Patent DE-3542161-A1 (DE)
Inventor: RIPPEL HARALD DR DIPL PHYS
IPC: G01J3/453
Filed: 1985-11-28
Abstract: To reduce the data rate of a digitalized measuring signal produced in Fourier spectroscopy, the analog signal representing the interferogram is mixed with a second electrical signal whose frequency is modulated in proportion to the deviation of the instantaneous actual speed of the moving mirror of a double beam interferometer from its constant desired speed. Only the difference frequencies produced as a result of the frequency mixing are digitalized and supplied to an associated computer for analysis of the interferogram. The digital measuring signal thus obtained is distinguished by a substantially reduced data rate without giving rise to additional errors in the frequency transformation. To produce the second frequency modulated electrical signal, a laser source is used which supplies a laser beam into the interferometer parallel to the measuring beam. The interferogram of the laser beam produced in the interferometer is converted by a second optoelectrical converter into an electrical signal frequency modulated in a desired manner and is supplied to a frequency mixer.

Title: Electromagnet with plug connection
Inventor: SCHROTT HUGO
IPC: H01F5/04
Filed: 1985-12-19
Abstract: An electromagnet with a plug connection is described, which consists essentially of a coil former (2) (composed of insulating material), a winding and an iron yoke. One of the end plates of the coil former has a connecting element (5) with a straight edge (4) on which metallic plug devices (6) are mounted which are electrically connected to the wire ends of the winding. The connecting element (5) is intended to be suitable for the connection of electrical supply leads (11) with the aid of so-called edge plugs (10) which can be plugged on using manufacturing robots. For rapid production of the magnet coils with the aid of automatic winding and manufacturing devices, suitable plug devices (6) and mounting devices (13) for the wire ends are proposed in order thus to prepare the connection of the wire ends to the plug devices (6). <IMAGE>

Title: Multi-stage combustion chamber for the combustion of nitrogen-containing gas with reduced NOx emission and process for the operation thereof
Inventor: BECKER BERNARD DR ING
IPC: F23C99/00
Filed: 1985-12-20
Abstract: The present invention relates to a combustion chamber for the combustion of nitrogen-containing gas with low NOx emission, consisting of at least one primary stage (7) for the precombustion of a fuel-rich mixture and at least one secondary stage (11) for residual combustion with large excess of air, the primary stage (7) having a multiplicity of inlet openings (5) distributed over its walls (8), which inlet openings (5) are connected to an inert material feed system (4). The inert material is preferably nitrogen. The feed of nitrogen through the walls (8) of the primary stage (7) displaces the combustion zone from the walls (8) and cools the latter, making possible a compact design despite high combustion temperature. Additional inlet openings (6) for nitrogen in the end region of the primary stage (7) make possible cooling of the combustion gases before the residual combustion with excess air in the secondary stage (11). The combustion chamber according to the invention makes possible the combustion of fuels having bound nitrogen with reduced NOx emission.

Abstract: A device for the positive attachment of a floor shell to a noise-damping housing of a motor vehicle comprises hook-shaped elements which are arranged on the incident air-flow side or floor side of the housing and against which a Z-shaped end region of the floor shell is supported. In order to achieve an operationally friendly attachment in which unintentional unlatching can be ruled out, the hook, which is of Z-shaped design and points in the direction of travel, is overlapped by a wall web formed by an opening arranged in the vertical leg of the Z-shaped end region. The horizontal leg of the end region of the floor shell is supported on the upper, horizontal leg of the hook, a horizontal leg region which lies lower down forming the swivelling region for the floor shell.

Title: Brake device for railways
Inventor: OLM KARL-HEINZ
IPC: B61K7/20
Filed: 1986-06-20
Abstract: The invention relates to a brake device using customary stop blocks which, when required, can be applied to the rails to be secured under manual or remote control. The standby function of the applied stop blocks and the direction of travel in which they are intended to act are monitored electronically by means of the holding device. This brake device in which the stop block is released from the holding device when a railway vehicle hits it is independent of the braking distance. The route can be secured on one rail or both rails with the brake device as required in order to avoid railway carriages rolling away. Derailing of the carriages with the otherwise considerable damage which results is thus avoided.

Abstract: The invention deals with a method of controlling winning machines, such as shearer loaders and selective-cut heading machines or the like, which are used underground and operated by remote control. In these cases, the control commands from the operator are sent to the machines wirelessly via radio control or else via control lines. A receiver located on the machine receives the control commands and transmits them to elements which convert these commands into the intended control actions. According to the proposal of the invention, the control commands are to be spoken by the operator and the spoken commands are to be transmitted wirelessly by means of microphone and transmitter or via control lines to the receiver of the machine to be controlled.

Filed: 1987-02-07
Abstract: With the aim of reducing the expenditure for protecting the MOS power transistors by the protection being taken over by the drive for the gate signal, this driving method, in which the current flows inversely from source to drain at least at times, is characterised by the fact that the gate is turned off in such a manner that, in a first process, the gate is discharged via an electronic switch, this switch is then opened again and when the drain voltage rises, the gate of the transistor is charged up via a capacitor voltage divider in order to put the transistor partly into a conducting state, and then the gate is discharged in a short time after a drain voltage of 1-50 % of the turn-off voltage has been reached.
