Title: Device for drilling holes for dowels and other connecting elements in wood or derived timber products
IPC: B27C3/06
Filed: 1988-02-26
Abstract: In the case of a device for drilling holes for dowels and other connecting elements in plate-wood or corresponding derived timber products, there is provided in a housing a drive motor which drives an output shaft mounted in the housing. A drilling tool for drilling the desired dowel hole is seated in the output shaft so as to be fixed in terms of rotation. The housing is connected to a footplate via a longitudinal guide, the guiding direction running parallel to the drill axis. In order to obtain an exact guidance of the drilling tool and a reproducible position with the aid of a stop template, a guiding bush for the drilling tool is inserted in the footplate. Two lateral stop faces are provided on the footplate symmetrically to the guiding bush.

Title: Solenoid valve having permanent-magnet latching
Inventor: KLOCKE HARALD ING GRAD
IPC: H01F7/18
Filed: 1988-03-25
Abstract: A solenoid valve having permanent-magnet latching is described, which can be operated in a monostable or bistable mode depending on the status levels of the available external control circuit. In the monostable mode, a circuit having a capacator becomes effective, the charging current of which capacitor, when the valve is switched on, holds a circuit of the same in the position where it is latched by a permanent magnet, and the discharge current of which capacitor, when the valve is switched off, causes it to return the original position. For the bistable mode, another circuit is provided which includes a reverse controller. The circuits are interlocked with one another. The required electrical power results from the energy requirement for switching the valve. The latching current corresponds to the leakage current from the capacitor, or falls completely to zero.

Inventor: JANKOWSKI JOZEF
IPC: C02F9/00
Filed: 1988-10-21
Abstract: The method of desalinating water of the invention consisting in that after chemical and mechanical pretreatment, saline water with a concentration of dissolved ions below 40 g/cu.dm is concentrated in a reverse osmosis installation 5 and then concentrated thermally, whereas saline water in which concentration of dissolved ions exceeds 40 g/cu.dm is concentrated directly thermally, is characterised by the fact that brine is concentrated in a single-stage evaporator 1, and during concentrating it is recycled in recirculation installation 6, while water vapour produced during brine concentrating is compressed in water vapour compressor 14 and returned to the single-stage evaporator 1 as a heating agent. Brine concentrated to more than 300 g/cu.dm of dissolved ions is directed via duct 13 to crystallizers 3 in which salts, mainly NaCl are precipitated. <IMAGE>

Title: Device for determining an angle of rotation
Inventor: NEUHAUS DIETMAR DR
IPC: G01B7/30
Filed: 1989-03-03
Abstract: In order to determine the angle of rotation of an encoding disc (10), there are contained in the electrically conductive disc strip-shaped resistance elements (21) which are electrically connected to the material of the disc only at their ends. Contact devices (K1-K4) scan the tracks in which the resistance elements are arranged. The respective disc sector can be determined by combining those tracks in which resistance elements are present, and the fine determination of the angle is performed within the disc sector by measuring the resistance between a contact element and the contact disc (10). <IMAGE>

Patent DE-3909274-A1 (DE)
Title: Pressure or force measuring device
Inventor: FURTMAYER KARL
IPC: G01L9/00
Filed: 1989-03-21
Abstract: A pressure or force sensor has a measuring body exposed to the force to be measured and a reference body, which are both supported on the housing via force measuring elements. In an evaluation circuit, the signals from the force measuring elements, the second time derivatives of these signals and, if necessary, also their first time derivatives are logically coupled in such a way that a signal representing the force to be measured is obtained which is largely independent of the dynamic intrinsic behaviour of the pressure sensor in the case of vibration of the housing and in the case of rapid alterations of the force to be measured.

Abstract: The ship's hull is designed to operate efficiently at both low and high speed. This is achieved by arranging that the stern part of the ship or the outer shell of the stern part is either completely or partly movable relative to the main part of the hull. When operating at high speed the stern part or outer shell is raised so that it is above the water-line (31) of the main part of the hull. When operating at low speed the stern part is lowered so that its undersurface is aligned with the undersurface of the main part of the hull. USE/ADVANTAGE - More efficient operation.

Title: Strip casting assembly - has die head with flow guides to prevent turbulence in molten metal passing to the mouthpiece
Inventor: EICHHOLZ HANS-HUGO
IPC: B22D11/118
Filed: 1990-03-05
Abstract: The die for a strip casting assembly has a flow extension (3) in a fixed mounting on the mouthpiece (2) of the die (1), to act as the die head for the molten metal to flow through. The casting tube (20) extends into the extension (3) vertically from above.

The die head (3) has a distribution trough (4) parallel to the longitudinal side of the outlet channel (6) and of the same length, with an overflow ridge (5) between them. This gives a syphon flow to the molten metal, and the casting tube (20) passes through the level of the molten metal (19) into the trough (4). The depest point of the distribution trough (4) is cladded with a beating plate (7), embedded in the fireproof cladding mass (8) of the trough (4), with a plate of high fireproof and erosion resistant sintered material. A buffer (9) is between the die head (3) and the die (1) as a clamped seal.
