Filed: 1979-03-02
Abstract: Two bars are employed to support a horizontal bar on a stand; and bar is fitted with an upper vertical guide for a bush, which can be moved along the guide and locked at a desired height via a handle. On bush is a plate, contg. a hole with a dia. corresp. with the bore dia. of a flange on the bottom edge of the upper part of a reactor. The underside of bar is fitted with another vertical guide and bush, employed in the above manner to carry a second plate with a hole corresp. with the bore dia. of an upper flange on the lower part of the reactor. The edges of the holes in both plates are surrounded by seals, so a gastight joint can be achieved between the two parts of the reactor.

Title: Automatic steering and position control of trackless vehicle - has twisted conductor pair inset in ground surface with on-board detector coil for position control
Inventor: TRETOW JOCHEN ING GRAD
IPC: G05D1/02
Filed: 1979-06-15
Abstract: The automatic guidance system for trackless vehicles includes a facility for position control. The system uses a conductor inset into the ground surface that is fed with an a.c.. supply to generate a magnetic field that induces a voltage in coils located within the vehicle For position control purposes, the conductor system is modified to a twin pair that cross over at periodic distances. The conductor pair is supplied with a.c. at one end and is terminated by a characteristic impedance at the other. An on- board coil responds to the variation in field caused by the crossover points and the generated signals may be used to determine position. Typically the cables are separated by a gap of 5 to 50cm.

Title: Encapsulated semiconductor device on support plate - has semiconductor element soldered between perforated plate and supply electrode and is encapsulated
Inventor: HEYKE KLAUS DIPL ING DR
IPC: H01L23/31
Filed: 1979-10-19
Abstract: The semiconductor element (1) of the device is soldered between a metal base plate (4) and a supply electrode (5). The assembly is encapsulated by insulating plastics, reaching up to the base plate, where it is anchored. The base plate has recesses (6), engaged by protrusions (7a) of the applied plastics (7). These recesses extend to the base plate surface, away from the semiconductor element. The recesses preferably pass through the entire thickness of the base plate. In this manner, the plastics encapsulation is prevented from being separated from the base plate while the device is also pressure-stabilised. The semiconductor component is typically a silicon diode chip. The chip and the supply electrodes are soldered to different base plate surfaces using soldering gaps (2,3).

In partic., the baked prods. produced in each inlay may each constitute one half of a hollow wafer or the like or may constitute two hollow prods. fitted one into the other. In the parent patent the space normally occupied by waste dough is filled by the material of the plate or strip. In the patent of addition the prodn. of more complicated prods., in partic. filled hollow baked prods., is achieved in a simple manner. In partic. foam-filled waffles can be produced.

Title: Defrosting of deep frozen sperm - automatically ejecting sperm ampoules from heated water after set time to avoid damage caused by higher than body temp. temp.
Inventor: SIMMET LUDWIG DR MED
IPC: A61D19/00
Filed: 1980-06-14
Abstract: Efficient defrosting of deep frozen sperm for artificial insemination is achieved at a temp. of 70 deg.C but the timing becomes very critical with as little as two seconds excess being very damaging. This problem is overcome by automatically removing the cage containing the sperm ampoules from the heated water after a set period of time. The cage containing the ampoule has a buoyant buoyant base and is retained below the surface of the electrically-heated water by an electrically-operated latch, e.g. a micro-switch or electro-magnet. After a set time a time switch operates the latch and the cage is ejected by its own buoyancy.

Title: Centrifugal force to linear motion converter - has two contra-rotating arms on common axle with mass transferable from one to other to cause centrifugal imbalance
Inventor: COOK ROBERT LEATON
IPC: F03G3/00
Filed: 1980-08-01
Abstract: The device to employ centrifugal force for use as linear motion utilises a pair of counter rotating arms about a common axle. One arm contains a mass splitable and transferable to the other arm and back again at one hundred and eighty degree intervals. The device may include a surface travel system or two of such devices may be employed in tandem for any mode of travel. When the mass is transferred from one arm to the other, an imbalanced centrifugal force is created which can be transformed to linear motion by mounting the device on e.g a wheeled carriage.

Title: RF pulse modulator circuit - adds output of three-port circulator and phase shifter to eliminate DC components
Inventor: WINDHORST PETER
IPC: H03K7/02
