Title: Electronic detector of passing train - uses oscillator sender stage with thyristor driven coil and receiver located on opposite side of rail
Inventor: ROBERT JEAN
IPC: B61L1/10
Filed: 1975-06-09
Abstract: A non-contact sensing unit consisting of an oscillator based sender and a receiver detects the passage of a train on a track. The sender output level is relatively high to minimize the effect of disturbances. The sender consists of a double base diode (T1) coupled to a variable resistor (R1) and a capacitator (C1) that operates as an oscillator with a frequency proportional to R1.C1. The generated pulses are coupled over a transistor (T2) to provide the trigger for a thyristor (Th1). The thyristor provides current for the sender output coil (Le) over a coil (L1) and diode (D1). Discharge of the capacitator (C2) produces a high level impulse from the output coil (Le). A receiver with a sensing coil is located on the opposite side of a rail. To ensure reliable operation each interruption results in three pulses being missed.

Title: Adjusting and actuating drive for valves - has magnetic powder coupling to ensure smooth and adjustable actuating torque
Inventor: WEIS ALFRED
IPC: F16D37/02
Filed: 1975-07-15
Abstract: Adjusting actuator for valves and slides applies specific forces over limited travel, and also reaches the end positions with a force depending on displacement or force. The drive ensures that the inertia effects of the motor masses do not result in dynamic increase of the actuating moment. A magnetic power coupling for limiting the torque transmits a uniform or arbitrarily adjustable torque over the whole valve adjusting range. The magnetic powder coupling is made in the form of a hollow dish. The output shaft (4) has a centrifugal force switch (6). On reaching the end position, or in case of standstill, the centrifugal switch (6) actuates the switch (9) for switching off motor (11). The switching is carried out via springs (8), switching plate (7) and roller (10). The switch (9) also controls the energising current for the solenoid (1) of the magnetic powder coupling and ensures correct stopping.

Title: Gasification of fuels in molten metal bath - with cooling of the reducing gas by mixing with blast furnace gas
Inventor: PASCHEN PETER DR
IPC: C01B3/02
Filed: 1976-05-08
Abstract: Sulphur-free reducing a gas mixts., made by known processes of gasification of solid, liquid or gaseous carbonaceous fuels with an oxidising medium below the surface of a basic slag-covered molten metal bath, are cooled to temps. suitable for metallurgical reduction processes by mixing the purified blast furnace or similar waste gases. For use as partial replacement for coke in blast furnaces for reduction of iron ores, and for production of spongy iron by direct reduction. The reaction gas is cooled from 1300-1450 degrees C. to the optimum value for blast furnace use (110-1200 degrees C.) or for direct reduction (800-1000 degrees C). Since the waste gases contain substantial amounts of unreacted CO and H2, the partial pressure of these components, and hence the reduction rate, is not significantly reduced.

Title: Cold rolled double tee beam - has double thickness flanges produced by repeated folding of uniform sheet metal strip
IPC: E04C3/07
Filed: 1976-07-31
Abstract: The cold rolled double-Tee beam has a web section (1) and two parallel end sections (2, 3). Each end section is produced by folding the sheet metal once through 90 deg. and twice through 180 deg.. Thus the tapered edge (6, 7) of the sheet metal is in contact with the outside of the 90 deg. radius (2a, 3a). The upper flange (3) of the beam has its edges (5) folded through 90 deg. so that they are parallel and point towards the centre of the profile. This increases the bending strength of the beam about the Y-Y axis and generally improves the stiffness of the profile beam.

Title: Artificial dog bone prodn. - from ground hide remnants, mixed with bonding agent e.g. gelatin and moulding
Inventor: CIECIERSKI WOLF
IPC: A23K40/20
Filed: 1976-09-29
Abstract: Artificial bones for dogs are made by grinding waste parts of hides and skins and by mixing the meal with a bonding agent. The mixt. of meal and bonding agent is then filled into a mould in the shape of abone. Pref. the hides or parts of them are first dried, broken to pieces of 1-2 cm. and ground to a particle size of 50-500 mu (120 mu). The meal is mixed with a bonding agent such as gelatin (from bones) soya bean germs or linseed, in wt. ratio of 50:50. The mixt. is cast into moulds or pressed with a force of 20 tonnes to the shape of a bone. This is a much more economical way than using strips of whole buffalo hide which have to be cut, soaked, preformed and pressed in a mould. The new method can be completely automated.
