Title: Clamping device for compass-saw blade
Inventor: SEYERLE JOERG DIPL ING
IPC: B23D51/10
Filed: 1993-09-01
Abstract: The invention relates to a clamping device for the sawblade on a saw having a reciprocating sawblade which can be clamped at one end, such as the compass saw. Such a device for clamping the sawblade on a compass saw exhibits a sawblade receiving means at the lower end of the push rod with a clamping screw arranged transversely thereon. In the case of a clamping device of this type, the clamping screw is intended to be capable of being operated directly by hand without the actuating members necessary on the clamping screw for this purpose being able to collide, during operation of the compass saw, with the framework thereof of add-on units located thereon. For this purpose, the clamping screw comprises a screw-bolt and a driver which is arranged thereon, can be operated by hand and has at least one essentially radially projecting toggle or wing. In this arrangement, the driver can be adjusted on the screw-bolt between a coupling position, in which it is connected in a rotationally fixed manner to the screw-bolt, and a pivoting position in which it can be rotated with respect to the screw-bolt.

Title: Process to remove cpd. such as halohydrocarbon from liquid medium - applies liquid regeneration agent to adsorber membrane stage
Inventor: STUERKEN KAI
IPC: C02F1/44
Filed: 1993-11-05
Abstract: A substance within a liquid medium (11) is separated from that medium as part of a process to regenerate an adsorbent. The medium (11) runs over the adsorbent which it subsequently leaves as a refined effluent (14), and the regeneration is achieved by means of an agent in which the desorbed components are taken up. The laden regeneration agent (16) is applied as a liquid to regenerate the adsorber stage onto a membrane stage (17), where it is separated into a regeneration agent discharge flow (19) and a regeneration agent-laden flow, and that the regeneration agent laden flow is at least partly available as a regeneration agent. USE/ADVANTAGE - The process regenerates an adsorber stage used for the sepn. of a substance from a liquid medium. Applications include the removal of halohydrocarbons, high b.pt. aromatic, alcohols or ketone impurities from water. The integration of the membrane stage in the adsorbent process facilitates a quasi-continual alternating process operation.

Title: Calculating position of vehicle using GPS satellite navigation system - receiving respective sets of navigation signals from satellites at base station and vehicle receivers, and calculating X,Y,Z error coefficients using second set and known position of second receiver to calculate position of first
Inventor: KYRTSOS CHRISTOS T
IPC: G01S1/00
Filed: 1993-12-01
Abstract: The position of a first receiver on or near the Earth's surface is computed using a second receiver of known position and a satellite navigation system having a constellation of satellites.  Two sets of navigation signals are received from the constellation, one at a first and one at a second receiver. Error coefficients for the position error of the second receiver in the X,Y and Z directions are derived from the second set of signals and the known position of the second receiver.  The precise position of the first receiver is derived from the first set of signals and the error coefficients. ADVANTAGE  - Enables precision of vehicle position estimation to be improved, by reducing linear errors in real time.

Title: Asynchronous motor speed control, esp. for combustion applications
Inventor: SCHWENDEMANN ECKHARD DIPL ING
IPC: F23N3/08
Filed: 1994-03-28
Abstract: A 3-ph motor (3), driving e.g. a fan, is supplied from a variable frequency source (3). The frequency, and hence motor speed, is determined (8) by a regulator (1) in which a speed and rotation sensing unit (5) is linked (5a,4a) via an optical coupler (11) to a program transmitter (4). The regulator operates a monitoring cycle in which the motor supply is briefly interrupted (6) and a half-wave rectified signal (US), derived (9) from the line voltage (UW-V) generated by the open-circuited motor, is compared (10) with a reference voltage (UB). This results in an output train (5a) of square pulses from whose frequency or duration the transmitter (4) determines the speed. By monitoring similarly all three line voltages the direction of rotation can also be established.
