Title: Coal carbonization plant - with coke desulfurizing reactor through which cleaned coke oven gas is circulated
Inventor: KELMAR JOHN J
IPC: B01D53/34
Filed: 1972-02-25
Abstract: In a coal carbonisation process, coke is transferred from the coke oven to a reactor to form a bed through which coke oven gas from which tar, ammonia and oil has been removed is continuously passed and finally cooled, preferably with waste heat recovery. The tar removed from the gas is used to produce coal tar pitch which is delivered to the reactor to gather with CaCO3 to desulphurise the coke and gas. Batches of coke are removed periodically from the reactor. The process minimises atmospheric and cooling water pollution, and provides enriched, purified coke oven gas.

Title: Hydraulically operated multi-plate clutch with driven shaft brake - automatically applies brake when clutch is released
Inventor: SHANKER BHAWANI DIPL ING
IPC: F16D67/04
Filed: 1973-06-07
Abstract: The driven shaft is integral with the clutch operating cylinder forming an annulus around the shaft. The operating piston and clutch plates are housed in this annulus and a coil spring exerts a force to keep the clutch disengaged. A second piston coaxial with the driven shaft is housed in a cylinder behind the operating cylinder. The second piston has a conical bore matching the conical part of the driven shaft passing through it. Belleville washers exert a load on the second piston so that a braking force is exerted between piston and shaft through their matching conical surfaces. The second cylinder communicates with the clutch cylinder so that when hydraulic pressure is applied the clutch is engaged and the brake released.

Title: Switch for reversing rectified output of A.C. generator - operates on reversal of rotation by shaft driven contacts
Inventor: THALHEIM KLAUS DIPL-ING
IPC: H02K11/20
Filed: 1973-07-03
Abstract: The switch is used in permanent magnet excited tachogenerators attached to reversing drives. A hardened steel ring is fastened to an extension of the generator casing in a manner to permit rotational movement. The ring carries contact fingers which operate in conjunction with contact springs each contact set being insulated from its support. Stops are fastened to the frame limit the travel of the ring in either direction. Means for driving the ring between these limits are provided from the shaft, which can take the form of a permanent magnet disc fastened to the shaft and separated from the ring by an air gap. The driving principle is that of the hysteresis motor. Alternatively a mechanical drive may be employed, for example through the friction in a ball race.
Patent DE-2334455-A1 (DE)
Title: Braking of numerically controlled drive - is for movement into rated position with constant detection of the actual speed
Inventor: GOSE HORST DIPL-ING
IPC: G05D3/12
Filed: 1973-07-06
Abstract: The actual speed is classified into speed ranges limited by thresholds. The remaining course to the rated position is detected constantly. A course indication proportional to the speed is calculated from the actual speed and a proportionality factor. The remaining course is compared to the calculated course indication. When they correspond to one another, the braking operation is started with a constant delay. It is interrupted when the course indication falls short of the remaining course on reaching the next lower speed range. These steps are repeated until the rated position is reached.

Title: Filling elongated consumable packages - delivers into vertical package then divided into sealed sections in horizontal position
Inventor: GUNDERMANN HELMUT DR
IPC: B65B37/18
Filed: 1973-12-24
Abstract: The process is particularly for use with additive mixtures during the pouring of molten steel into chills, or for proportioning of reactive mixtures in vessels in controlled manner. After metering and mixing the ingredients, the mixture is delivered by a vibratory conveyor to the filler opening of the packing, which is in a vertical position, and which is consumed together with the contents in use. A predetermined quantity of mixture falls freely into the stationary packing, which is then swung into the horizontal position. The packing is finally divided into sealed individual chambers by squeezing it together at various points. Before the dividing operation, the packing can be rotated in the horizontal position several times about its lengthwise axis, or shaken.

Abstract: The valve consists of a valve body with cylindrical chamber and two inlet openings which are in line with one another and an outlet opening at right angles to the inlets but located on a different plane. A cylindrical valve is mounted in the valve chamber on a valve stem and can be moved up and down to control the degree of opening of the insets. The valve stem protrudes through a cover on the valve body. The cylindrical valve is prevented from rotating by a key which engages with a slot in the valve. A segment shaped valve is mounted on the valve stem above the cylindrical valve body. The segment rotates with the valve stem and is used to control the ratio of the two inlet streams. In the extreme positions either on or the other of the inlets is closed.

Title: Switch electronic chatter preventing circuit - has flip-flop in parallel to mechanically moved contact and limited voltage application
Inventor: FAHRENSCHON KURT DIPL PHYS
IPC: G04G5/00
Filed: 1974-10-10
Abstract: The electronic chatter preventing circuit is intended for mechanically actuated switches and uses a flip-flop whose switching path is parallel to the mechanically actuated contact. The reference potentials, necessary for the operation of the flip-flop, are applied only during the actuation of the switch or its time fraction so that only during this time power is applied to the chatter preventing circuit. Preferably the application of the reference potential is carried out over at least one additional switch in time controlled coupling with the protective switch. This second switch has a phase shift with respect to its breaking and making times. The additional switch may be of mechanical or electronic type.
