Title: Circuit layout and changeover switch for braking AC commutator motor - has top-dead-centre toggle action switch with intermediate dwell position to prevent mains short-circuit by arcing at contacts during braking
Inventor: ROTTMERHUSEN HANS HERMANN
IPC: H02P3/06
Filed: 1992-08-21
Abstract: The circuit for braking an AC commutator motor (6,7) as employed in electrical hand tools provides a four contact (I,II) changeover switch (4) to promote rapid deceleration by short-circuiting the motor windings at switch-off. The switch has a top-dead-centre i.e. toggle action which is largely independent of user inconsistencies during operation and provides a short dwell in the centre position (8). The changeover from device to braking condition thus incorporates a moving contact (S1,S2) travel time which is greater than the duration for inductive arcing to ensure mains isolation before motor short-circuit via the bridge (5) and limiter (2). USE/ADVANTAGE - Reliable and safe means of preventing mains short-circuit due to arc-over at switch contacts on changeover to braking. Reduces excessive commutator sparking and brush wear imposed by braking action.

Title: Faulty solder joint test method - using laser beam to generate ultrasonic signals which are sensor monitored
Inventor: HAMANN CHRISTOPH DIPL ING
IPC: G01N29/24
Filed: 1992-10-09
Abstract: Solder joints between electronic component leads (2) and connection points on conductor plates (3) are tested by irradiating the joint with a laser beam which does not visibly affect the heated surface. The heating effect gives out an ultrasonic signal which passes through the joint and is detected by a sensor (4). The detected signal is compared with signals give off by previously well soldered joints and the quality of the joint ascertained. ADVANTAGE - Effective destruction-free testing method which is quick to carry out.

Title: Monitoring the quality of a lap weld - by measuring the temp. at the back of the weld and adjusting the laser beam accordingly
Inventor: DEINZER GUENTER DIPL ING
IPC: B23K26/244
Filed: 1992-10-12
Abstract: In the laser welding of two overlapping sheets, lap weld (8) between the two overlapping sheets (5,6) is monitored by measuring the temperature at a point (15) directly opposite the focal point of the laser beam (10) at the back of the sheet assembly. This temperature is compared with an optimal temperature and a control signal is sent to the laser beam control which changes the welding energy via the laser power. Pref., the power flux density at the focal point (10) is adjusted by varying the focal length and/or the focal diameter of the beam. The laser source is a CO2-laser and the temperature sensor is a thermo-camera (12). USE/ADVANTAGE - Esp. in constructing automobile bodies. The weld bead has a high quality and thereby leads to a reduced reject rate.

IPC: C05F11/00
Filed: 1992-11-06
Abstract: A biodegradable polymer mixture is proposed which essentially comprises starch and at least one hydrophobic polymer. The hydrophobic polymer should be at least substantially biodegradable and thermoplastically processible, and the mixture with the starch should contain a polymeric phase promoter or a macromolecular dispersant, so that the starch is present in the mixture as the disperse phase with the hydrophobic polymer as the continuous phase, and the phase promoter or the dispersant is responsible for the molecular coupling of the two phases. The starch used is preferably thermoplastic starch prepared by means of sorbitol or glycerol essentially in the absence of water. The preparation of the biodegradable polymer mixture should likewise take place essentially in the absence of water.

Patent DE-4240578-A1 (DE)
Inventor: HODDE ANDREAS DIPL ING
IPC: G01S5/14
Filed: 1992-12-04
Abstract: The procedure for defining position by means of an asynchronous cellular mobile radio system is dependent on only minor additional costs for its use. The parameters required for defining position are reported to the mobile radio terminal even while the connection is being set up, for technical radio reasons. Only minor changes are carried out in the mobile radio terminal. By evaluating range-dependent parameters which are reported continuously to the mobile radio terminal whenever a connection is set up and in order to maintain the connection, it is not only possible to identify the radio cell in which the mobile radio terminal is located, but the location accuracy can be improved down to a circular ring. Data from adjacent radio cells are included in the calculation to decide on a circular ring segment from a circular ring. <IMAGE>

Title: Vibratory sieve with tapping system for periodic striking of sieve by bouncing bodies - impact of bouncing-bodies is controlled by selection of distance between sieve and rebound base, or frequency and/or amplitude of base
Inventor: FROELICH BERNHARD DIPL ING
IPC: B07B1/46
Filed: 1993-07-16
Abstract: A vibratory sieve has a flexible sieve layer (8) and a tapping system with bouncing bodies (15) which are located between the sieve layer (8) and an underlying rebound base (14) and which are set in constant motion by sieve vibration for impacting against the sieve layer (8). The novelty is that impact of the bodies (15) against the sieve layer (8) can be controlled to occur only at particular time intervals by selection of the distance between the sieve layer (8) and the rebound base (14) and the frequency and/or amplitude of the rebound base. The bodies (15) are rubber(-coated) balls or brush-like shaped parts. The rebound base is a non-flexible woven material (esp. a noise-damping woven plastics material) which has a larger mesh that of the sieve and which is adhesively bonded to an enclosing sieve frame (7). The sieve layer (8) is fixed, esp. adhesively bonded under tension, to the frame (7). Vertical partitions (11) are located between the sieve layer (8) and the rebound base (14) to form compartments filled with a fixed number of bouncing bodies (15). USE/ADVANTAGE - The sieve layer is struck by the bodies only at certain intervals to clear blockages, so that it is subject to less wear and has an extended service life.

Filed: 1993-08-26
Abstract: In the case of a textile fabric for the lining of pipelines, having two outer woven, laid or knitted webs formed from glass fibre filaments and having foamed microballoons arranged between these webs as an intermediate layer, the invention proposes that the intermediate layer should have unidirection glass fibre filaments running in the longitudinal direction of the pipe lining. In this way, the textile fabric has a minimal longitudinal extensibility and permits a precise determination of the nominal diameter of the tube to be produced, this tube having a radial extensibility.
