Patent DE-2842718-A1 (DE)
Title: Electrostatic precipitator for dust-laden gases - with granular insulating particles circulating between charged electrodes
Inventor: KANDA TETSUO
IPC: B03C3/45
Filed: 1978-09-30
Abstract: An electrostatic precipitator for the dedusting of gas passes the gas through the gaps of a granular insulating material between two electrodes to which a voltage is applied. The apparent resistance of the packed insulator is kept >5.108 ohm.cm. One of the electrodes has sections with points where a high electrostatic field intensity is produced. The arrangements requires low voltages to produce multipolar discharges. The regeneration of the dust laden particles is simplified. The insulator can at the same time ba a catalyst so that the dust adheres to the surface and the catalytic activity is not affected.
Patent DE-2843078-A1 (DE)
Title: HV breaker with pressure controlled piston-cylinder units - has mechanical coupling common to all pistons preventing control action on actuating force failure
Inventor: BEIER HELMUT ING GRAD
IPC: H01H33/32
Filed: 1978-09-29
Abstract: The drive is intended for the control of a multi-pole, sulphur hexafluoride insulated circuit breaker and contains several piston/cylinder units (1, 2) which can be controlled by a pressure medium. For all pistons (3, 4) is pivoted a common mechanical coupling which prevents any postion change of the units, when the actuating force fails at least at one unit. Preferably a coupling rod (18) is used for connecting the pistons, a switching drive being located between this rod and each piston. On one side the pistons may be continuously under the OFF force of an energy store, while permitting engagement by ON pressure. This pressure may be smaller or equal to the OFF force. One piston side may be engaged by a hydraulic pressure line (6, 7), incorporating a non-return valve (12, 13).

Title: High temp. shutter valve for hot wind on blast furnaces etc. - has several water cooling channels reducing thermal stresses in valve
Inventor: SCHNEIDER HEINZ
IPC: F16K49/00
Filed: 1978-11-22
Abstract: The valve contains water cooling pipes bent into rings and running along the sealing rails used for the driven shutter plate. Between the flanges employed to connect the valve to a hot wind duct are radial walls which extend over >=180 degrees in the lower part of the valve, and are joined by an axial wall to form water cooling channels with holes leading to the pipes. Pipes are pref. also joined to a circular wall forming the bore of the valve and also functioning as the internal walls of additional water cooling channels of which one wall consists of a radial wall. The object is to increase the efficiency of water cooling of the valve and to reduce thermal stresses in the valve.

Title: Mine or tunnel gallery backfilling support mat - has wire net supported solely by lengthways bars with bent ends
Inventor: SCHAEFER BERND
IPC: E21D11/15
Filed: 1978-12-28
Abstract: A series of lengthways and cross bars, and a net of thinner wire, are incorporated in the mat used in gallery support system in underground mines or tunnels.

Title: Electroslag remelting of consumable electrodes - where rectifiers prevent positive voltage on mould, so mould wear by electro:erosion is eliminated
Inventor: MEDOVAR BORIS I
IPC: H05B3/00
Filed: 1979-03-05
Abstract: The plant includes a transformer with a sec. winding connected to >=2 consumable electrodes the bottom ends of the latter being immersed in a melt in a mould which rests on a base. Both the mould and its base are connected via rectifiers to the sec. winding of the transformer so that only d.c. flows from the mould and its base through the rectifiers to the sec. When 3 electrode holders are used with a 3-phase supply connected in delta, the mould and its base are pref. connected via min. three rectifiers to the power supply. The overall result is that a positive voltage cannot be created on the mould walls, so the life of the mould is increased and it does not contaminate the melt.

Title: Radio control TV game - has several remote player transmitters using TDM in IR band to control central TV receiver game
Inventor: NISSEN NICO DIPL ING
IPC: A63F13/20
Filed: 1979-03-08
Abstract: TV game transmission system uses digital t.d.m and a central TV and processor and TV receiver controlled by several remote players. A digital signal synchronisation and protocol ensures recognition of the correct commands and information for each individual player unit which may be of a different type and in a different state of play to the others. The TV receiver recognises synchronisation pulses denoting the start of instructions, instructions at predetermined time intervals and a closing synchronisation pulse sequence. Each player unit has, in addn. to the game play keyboard, controls for the operation of the TV receiver, e.g. contrast. Players transmit multiplexed signals according to a time code to the TV receiver and these control signals are modulated onto a carrier in the infrared band.

Title: Gas density monitor for gas filled HV switchgear - has bourdon tube enclosed in gas to operate indicator
Inventor: KLOETZNER GERD DIPL ING
IPC: H01H33/56
Filed: 1979-06-29
Abstract: The safety device for gas filled high voltage switchgear is an indicator which registers the density of the gas inside the switchgear. The device has a housing (12) mounted on the switchgear housing (14) and containing a Bourdon tube (28) which operates an indicating pointer (50) moving around a circular scale (52). The Bourdon tube has a connection (42) at one end, for the mechanism driving the pointer, and at the other end is attached to a tube (22) screwed into hole (18) through the switchgear housing, and with a hole (24,26) through it, so that the gas can enter the indicator housing. The density of the gas inside the two housings is therefore approximately equal. The indicator can incorporate electrical contacts operated by a fall in density to operate an alarm.

Title: Hose with embedded wires - mfd. with intermediate heating for improved adhesion
Inventor: ANDERS UWE DIPL PHYS
IPC: B29D23/00
Filed: 1979-12-01
Abstract: High-pressure hose consisting of an inner core with a wire reinforcement and an outer sheath is produced by injecting a rubber mix over a plastic mandrel, braiding the core and applying the sheath. Before the last operation, the blank is quickly heated to 200-300 deg.C as measured at the wires, for 15-40 sec and held at a temperature of over 150 deg.C for at least 30 sec. This ensures a secure adhesion between inner core and outer sheath with the inserted wires in an operation which can be integrated in a normal production line.

Title: Vitreous blast furnace slag mfg. plant - where molten slag is poured into deep grooves between metal plates for rapid solidification
Inventor: ANDO RYO
IPC: C21B3/08
Filed: 1979-12-18
Abstract: The molten slag leaving a blast furnace flows down a chute and a funnel onto the top surfaces of rectangular, metal cooling elements (2); and elements (2) are joined together to make an endless conveyor belt travelling horizontally below the stream of slag and mounted on a pair of rollers. Each element consists of a row of parallel metal plates (14) with tapered top edges. Plates (14) are spaced apart, so they form deep, narrow cooling grooves (13) aligned parallel with the longitudinal direction of travel of the conveyor belt. The top edge of each groove (13) is 3-10 mm wide, and the groove depth is 2-20 times its width. The slag flows into grooves (13) so it is rapidly cooled and solidified to form a vitreous granulate. In the bottom part of each groove is a sliding plate used to eject the granulate. The vitreous slag obtd. is practically water-free, and is suitable for use in cements or for mfg. a calcium-silicate fertiliser.

Title: Ionisation of organic samples on conveyor belt - which carries sample from liq. chromatographic appts. into mass spectrometer
Inventor: BRUNNEE CURT DIPL PHYS DR
IPC: H01J49/14
Filed: 1980-05-14
Abstract: Conveyor belt carries the sample into an ionisation chamber located on the inlet of a mass spectrometer; and slow carriers are pref. fed into, or generated in, the chamber, to ionise the sample. Ionisation pref. occurs at an elevated temp., e.g. at 200 degrees C., esp. by creating the large carriers in a methane plasma. Alternatively, a laser beam may be used to ionise the sample via a window in the chamber, so the beam impinges on the belt. Sensitive organic molecules can be ionised without being damaged or destroyed.
