Title: Channel for outdoor mobile equipments cable - has one side steeply inclined to form overhang that shields cable from direct sunlight
Inventor: STROECKER GUENTER
IPC: B66C13/12
Filed: 1974-07-25
Abstract: The channel, for a cable serving a mobile piece of equipment, has one side (17) deeply inclined to shield the cable from direct sunlight. The open-topped channel may be set into the ground at an angle such that one side has an overhang that shields the cable from direct radiation or it may be formed by a supported duct whose one side is bent to form the overhang. The equipment is mounted on a trolley that straddles the channel and has a drum from which the cable unwinds as the trolley moves along and is lowered into the channel.
Patent DE-2446976-A1 (DE)
Title: Clutch disc for motor vehicles - has double damping mechanism using springs which engage on a centre element of clutch disc
Inventor: MAUCHER PAUL DIPL ING
IPC: F16F15/123
Filed: 1974-10-02
Abstract: The clutch takes up very little axial space; no more than that required by other clutches with a shock absorbing device between the friction lining and the hub. The first damper is set at one torsion angle and the second operates through the first and via a further torsion setting. The force accumulator spring for the first damper and also that for the second damper engage on a common element of the clutch disc. This is fixed to the lining carrier plate. The output part of the first damper is within the axial dimension of the hub for the second damper. Both output parts have a common mating profile such as the toothe gearing on a drive shaft.
Patent DE-2450731-A1 (DE)
Title: Germicidal treatment of circulated swimming pool water - with ozone and hydrobromic acid
Inventor: BACHHOFER BRUNO
IPC: C02F1/76
Filed: 1974-10-25
Abstract: Ozone treatment of circulated swimming pool water is improved by introduction of HBr pref. into the circulation pipe just before the ozone inlet. The water is then passed through a filter and released back into the pool. The introduction of HBr is pref. carried out intermittently after the cleaning of the filter. By this method the consumption of HBr can be reduced to 4001 of 63% HBr soln. per m3 of the total water vol. per year. The process proceeds according to the formula 2Br- + 2H+ +/3 Br2 +O2 +H2O and Br2 + H2O HBr + H+ (OBr)-. Thus ozone, which exerts irritating effect on the human skin is decomposed and Br2 is formed instead; the latter exerts strong and prolonged germicidal effect (lasting much longer than the action of Cl2). Br2 reduced to Br- is recycled and reoxidised by ozone. Thus, the consumption of HBr is low (just to replenish bromine loss in organic impurities filtered off.).

Title: Axially rotatable bearing for swivel chairs - comprises two interfitting threaded sleeves mounted on central tube
Inventor: LENDLIN OSKAR INGEMAR
IPC: A47C7/00
Filed: 1974-11-19
Abstract: The swivel chair comprises a seat with back rest and lower support frame, with the seat itself being fastened in a downwardly extending vertical column which is displaceably guided in a tube. Two spaced bearing plates which serve as handles are fastened at right angles to the tube with a cylindrical external threaded bush being fastened between the two plates by bolts. An internally threaded sleeve is screwed over the cylindrical bush and connected to the support frame by a bracket. These two interacting threads form bearing surfaces to take up the stresses and transfer the forces from the seat to the frame. The threads also allow the bush to rotate relative to the sleeve so that the seat can be swivelled by rotating the column about the centre axis of the sleeve and bush. This rotational movement is defined by the bracket. The seat can be secured against rotation by a hand-operated lock with arms engaging round the tube.

Title: Desalination plant, utilising a heat pump - in which heated stream of air is contacted with salt water and subsequently pure water is condensed
Inventor: SCHUELLER KARL-HEINZ
IPC: C02F1/10
Filed: 1975-11-28
Abstract: Sufficient heat for picking up the water vapour is imparted to the carrier air stream by means of a heat pump. The air is then mixed with the water vapour, and the condensation is effected by mixing into the carrier air, the cold air stream coming from the heat pump. The heat pump consists of a compressor with its shaft coupled to a drive such as an electric motor or an internal combustion engine, and to a decompression turbine. Its suction side is connected to the outside air whilst the compression side feeds the primary side of the first heat exchanger into the turbine. The outlet of the secondary side of the first heat exchanger is connected with the mixer for heated carrier air and salt water.

Title: Form punch on power press for straightening shafts - has tapered load transmission shoulders to compensate shaft variations
Inventor: AUGUSTIN HANS-GEORG DIPL ING
IPC: B21D3/16
Filed: 1975-12-18
Abstract: The power press (1) is used for straightening crankshafts (6) and has a top tool assembly with spring-loaded pressure plates (7). The two parallel plates (7) have opposing internal tapers (4) through which the bending load is transmitted from the press to the crankshaft. Since the two pressure plates (7) are able to move along the tool axis both away from and towards each other, variations in the crankshaft diameter (D,D1) can be compensated. Thus the bending load applied to the crankshaft is uniform over the whole contact area despite varying shaft diameter.

Title: Easily removable clamp for securing frame sections together - fixes wall sections to profile frames using hammer bolts with flush fitting head
Inventor: WEIS ROLAND
IPC: F16B7/04
Filed: 1976-05-29
Abstract: The connection is used e.g. for fixing a wall section to a frame made from a profile rod. The section of the rod is approximately square has 'T' grooves along the four sides. The clamping arrangement is mounted in a corner of the wall section near its side edge. The clamp consists of a bolt which is loaded axially by spring tension.

Abstract: Process for ensuring and maintaining the quality of an observation hole, esp. in a blast furnace where an observation device is employed, or an optical measurement made, along the sighting axis of a small hole (e.g. with a dia. below 10 mm) made in a screen inserted between the device and the interior of the zone being observed; and where a porthole is located between the device and the screen. A current of dry compressed gas is blown between the porthole and the screen, the gas escaping via the side of the observation hole opposite the porthole, and the side of the screen facing the zone being observed is subjected to a cleaning operation e.g. by scraping. The gas is pref. used continuously whereas the cleaning is discontinuous. Used in observing or monitoring the temp. distribution across the top of the charge in a blast furnace, the existence of hot spots, etc., esp. when a high gas pressure exists in the furnace. The current of compressed gas keeps the porthole clean.
