Patent DE-3145958-A1 (DE)
Title: Transport belt for draining, washing and conveying granular materials
Inventor: MEIER-DOERNBERG KARL-ERNST DR
IPC: B03B5/00
Filed: 1981-11-20
Abstract: The application relates to an additional device for belt conveyors, with whose assistance readily free-flowing transport material, such as, for example, sludgy gravel, can be continuously conveyed and drained. The additional device closes off the lowest region of the conveyor-belt trough from the transport material, thus forming a free channel in which the fluid can accumulate and run off. In the case of long and rapid-moving transport belts, or transport material which is difficult to drain, the design described in Fig. 1 and the subclaims 4 to 7 is particularly suitable. The covering profile in this case is a continuous extruded section (3) which is laid around the conveyor belt and rotates therewith. The liquid portion entrained in the collecting channel in the transporting direction is here entrained by the covering profile and returned to a suitable flow-off point (11). <IMAGE>
Patent DE-3203400-A1 (DE)
Title: Vacuum system
Inventor: WIELAND ALFRED DIPL ING
IPC: B60T13/52
Filed: 1982-02-02
Abstract: For producing a defined vacuum, a vacuum system is proposed which comprises a vacuum pump, an electric drive motor for the vacuum pump and a pressure switch. The vacuum pump is arranged in a positively interlocking way between the pressure switch and the electric drive motor. A compact unit is thereby created which takes up little installation space, has a low weight, does not require any additional air-carrying lines between pressure switch and vacuum pump and can be attached to existing vacuum-operated devices, without modifying these, at low installation cost. The invention is particularly suited to motor vehicles with vacuum-operated brake boosters. Such brake boosters in fact have the disadvantage that they are fully functional only when the vehicle engine is running. The proposed vacuum system overcomes this disadvantage and makes an important contribution to driving safety in that it is connected to the vehicle battery and then put into operation if a defined vacuum is not present for the brake booster. <IMAGE>

Title: Device for the production of an elliptical hole in the wall of a tube
Inventor: LARIKKA LEO
IPC: B21C37/29
Filed: 1982-03-06
Abstract: Device for the production of an elliptical hole in the wall of a tube, having a housing (20), a drive (10), a rotatable spindle (3) with a tool at the end, the spindle (3) being axially displaceable, allowing the tool (1) to pierce the wall of a tube. One problem consists in developing a device which is capable of producing elliptical holes of a desired size and configuration with different tube diameters. To solve the problem, the tool (1) at the end of the spindle (3) is secured at a distance from the central axis (3a) of rotation of the spindle and is inclined at an acute angle ( alpha ) to the central axis (3a) of rotation. The spindle is provided with a guiding device (13, 14) for the forced advance of the spindle (3) in its axial direction during rotation in the course of a work cycle. The configuration of the guide surface (13) on the spindle (3) changes with different distances from the central axis (3a) of rotation of the spindle (3) and the guiding body (14) can be displaced radially relative to the spindle (3) and also axially. <IMAGE>

Patent DE-3229609-A1 (DE)
Title: Thermal flowmeter
IPC: G01F1/68
Filed: 1982-08-09
Abstract: A thermal flowmeter for determining the flow rate of a fluid in a measuring channel, having two temperature-dependent resistors which are fitted one behind the other in the flow direction on the measuring channel, form a first series circuit and, with two further resistors which form a second series circuit, form a bridge circuit. In order to detect the temperature difference between the resistors of the first series circuit, the current supplying the bridge circuit has the temperature-dependent resistors. The two resistors of the second series circuit are likewise constructed as temperature-dependent resistors which are fitted to the measuring channel in each case at the same height as the resistors of the first series circuit, in the flow direction of the fluid. The direction of the current in the first series circuit is opposite to the direction of the current in the second series circuit.

Title: Light-deflecting device for deflecting in the x- and y-directions by means of mirrors
Inventor: GUGG ANTON DIPL ING
IPC: G02B7/182
Filed: 1982-09-04
Abstract: The heretofore spatially separated deflecting mirrors have not been adequate for the complete exploitation of a flat-field scanning lens, i.e. its freedom from distortion, processing field size and beam diameter. The complete exploitation of such a lens is achieved by means of deflection in the x- and y-directions using a mirror which is mounted about a centre point. Moreover, completely symmetrical imaging characteristics are produced in all other light-deflecting systems which deflect in the x- and y-directions. <IMAGE>

Patent DE-3347637-A1 (DE)
Title: Hydraulic device
Inventor: WITTICH KURT
IPC: F15B1/027
Filed: 1983-12-30
Abstract: Disclosed is a pilot valve for a hydraulic device, such as an accumulator loading valve, which can be operated in a bistable manner as a function of the accumulator pressure and is almost insensitive to pressure peaks occurring briefly in the accumulator line. Here, the pilot valve comprises two interacting pistons which are constantly in contact. A greater resistance is offered to the movement of the pistons in the one direction than to their movement in the other direction. This resistance of different magnitude is brought about by a space which is filled with pressure medium, is in contact with an annular space in the housing via a restricting connection, is defined by the two pistons and a section of the valve housing and increases or reduces its volume as a function of the direction of movement of the pistons. Furthermore, the movements of the pistons are thereby greatly dampened so that they scarcely react to the occurrence of pressure peaks.
