Title: Drive and control for four synchronised motors - has three phase comparators controlling excitation fields according to static inverter supply phases
Inventor: WEIDMANN HARTMUT ING GRAD
IPC: H02P5/50
Filed: 1974-06-24
Abstract: The drive and control circuit for four or more synchronised motors has three phase comparators comparing the phase of the first motor supply with those of the remaining motors supplies. The phase signal is obtained in each case from a transformer whose primary is formed by any motor supply line. The phase comparators control the excitation fields of the three motors to be synchronised. The first motor acts as the master. The supply to the motor is obtained from a multiple converter consisting of four rectifier/ static inverter pairs. The advantage of the circuit lies in its being purely electric.

Title: Buried pipeline search and test - by geomagnetic location and overburden determination by electromagnetic and echo sounding readings
Inventor: EDELMANN HANS DR
IPC: G01V3/10
Filed: 1975-07-09
Abstract: Pipes for the transport of oil or natural gas from offshore wells which are buried in trenches at the bottom of the sea are located and checked by a geomagnetic measurement. This establishes the location and the run of the pipeline. The distance between measuring point and pipeline is measured by an electromagnetic measurement. Comparison of the latter with an echo sounding measurement between measuring point and surface of overburden reveals the thickness of the latter. This system is a quick and reliable method of locating a buried pipeline. It also provides continuous readings of the thickness of the overburden and of any displacements. Individual pipeline sections can be identified by specific magnetic properties.

Title: Controlled phase circulation in liquid extractor - having overflow weir to adjust proportion recycled
Inventor: KRAUS ERHARD
IPC: B01D11/04
Filed: 1975-09-12
Abstract: Controlled recirculation of one of the phases in a liquid extractor is effected by sepg. off the fraction of the phase to be recycled using an adjustable weir. The weir height is kept the same for both fractions so as not to interfere with the separator, only the proportion being altered by movement of a baffle. The overflow weir can be mounted inside or outside the separator. This divides the recycled phase in proportion to the throughput of the other phase, maintaining the liquid head the same on both sides. The weir height can be adjusted. It can be either round or rectangular. Used with liq. extraction systems using the mixer-separator principle.

Title: Plastic ski with steel edge - has steel edge welded into plastic ski close to running surface
Inventor: SCHWEINSBERG HUBERT
IPC: A63C5/048
Filed: 1975-09-29
Abstract: This ski is made in the normal way of a thermoplastic material. A slot (4) is then cut into each side close to and parallel with the running surface (2) into which is set an L-shaped stel edge piece (6). The height (h) of the edge rail (6a) is less than the distance (a) between the slot (4) and the running surface. The edge of the running surface (2) is cut back to bring the outside of the edge rail (6a) level with the side of the ski. The fixing piece (6b) of the edge piece (6) has a number of 'T' shaped slots (6d). The ski is assembled by fitting the edge piece (6) into the slot (4). The ski is then held in a press while an electric current is passed along the edge piece (6). The head caused by the electricity softens the plastic so that plastic is forced into the 'T' slots (6d) in the fixing piece (6b). This method results in an extraordinarily strong union of the steel with the plastic so that it is no longer possible for the steel edging to be torn out.

Title: Energy storage system for vehicles - uses several flywheels and friction clutches to give progressive acceleration and braking
Inventor: SATTERS ALEXANDER
IPC: B60K6/10
Filed: 1976-01-21
Abstract: The vehicle drive shaft turns by means of a clutch a second shaft (3). The second shaft is geared (4) to a third shaft (8) divided into sections and coupled by friction clutches (22, 23, 43). Each shaft section carries a flywheel (10, 20, 30, 40) and a revolution counter. When the vehicle is to be retarded the first clutch (1) is engaged by a switch unit (57) to accelerate the first flywheel (10). The corresponding revolution counter gives a signal to a regulator (50) when the first flywheel speed is equal to the drive shaft (2) speed. The signal causes the second clutch (23) to engage and rotate the second flywheel (20). The process is repeated until the drive shaft speed falls below the flywheel speed. The first clutch (1) is then disengaged together with the individual flywheel clutches. The first clutch is re-engaged by the switch unit (57) to return the energy stored in the first flywheel back to the drive shaft.
