Title: Hydraulic damper for servo cylinder drives - has high pass filter circuit with transverse throttle
Inventor: PONGRATZ HANS W DIPL ING
IPC: F15B13/043
Filed: 1977-03-04
Abstract: The shock absorber and damper for hydraulic servo cylinders and motor drives, has high pass characteristics, uses a symmetrical high pass filter circuit with a transverse throttle (24). This has two laminar throttles (24-26), and two hollow chambers (18, 19) with elastic dividing walls (22, 23), which react to differential pressures by allowing the passage of a measured amount of oil. The dividing walls consist of elastic plates, which are formed and positioned so that the pre-tensioning force and the external rigidity factor controlling the transmission factor of the plates, balance each other, due to a series arrangement.

Title: Cleaning cold rolled steel - by applying a wetting agent and washing with high pressure water using a slot-type nozzle
Inventor: SAITO TAKAO
IPC: B21B45/02
Filed: 1977-03-08
Abstract: Cold rolled steel in the form of plate, sheet, strip or rod is cleaned to remove oil residues and metal (iron) particles by applying to the surface a wetting agent followed by spraying with water under pressure in such a way that a curtain of water is formed in a straight line across the whole width of the plate or sheet, using a nozzle of slot type, or several such nozzles. This removes residues of lubricant from rolling, iron powder and simultaneously the wetting agent. The method is economical, simple and effective, and replaces the costly electrolytic procedure coupled with brushing.

Title: Irradiated fuel storage pond with shielding above water - pref. by steel plates projecting from top of wall over water
Inventor: SCHNEIDER WILFRIED
IPC: G21C19/07
Filed: 1977-07-08
Abstract: A fuel element storage pond or pool for nuclear plants has a horizontal shielding plate extending from the top of the pond wall out over the surface of the water. The free edge of this plate may have a further, downward projecting plate to provide additional shielding. In nuclear storage plants for fuel elements, whether in a power plant or in a processing plant. Since the radiation at the top of the pond walls affects personnel working at the top, the use of an additional shielding plate in this region considerably reduces the effective radiation level.

Title: Lubricants for deflated tyres - comprise aq. glycol, polyethylene oxide, polysaccharide and cellulosic fibres
Inventor: KUAN TIONG H
IPC: B60C17/10
Filed: 1977-07-11
Abstract: Lubricants for pneumatic tyres for use when the tyre is operated in a deflated condition comprises (a) 100 pts. wt. of a mixt. of 4 parts ethylee glycol and >=1 part H2O; (b) 0.05-2 pts. wt. of a polyethylene oxide with a mol. wt. of ca. 500.000; (c) 0.15-2 pts. wt. of a polysaccharide with a mol. wt. of >=10.000; and (d) =8 pts. wt. of cellulose fibres with a length of 400 mu. The viscosity of the lubricant must be such that the fibres remain dispersed when the tyre is subjected to a centrifugal force of 200-g at 70 degrees C. Suitable polysaccharides include starch, cellulose and hemicellulose derivs. and natural gums and mucilages. The lubricant pref. has a viscosity of 100.000-400.000 cP at 25 degrees C, which should increase by >=10% at 85 degrees C. When applied to the inside wall of the tyre, the lubricant reduces the friction and heat generated by the rubbing of the upper and lower halves of the sidewall, so that the tyre can run flat for some time after a puncture. The lubricants are comparable with rubber, have good thermal and shear stability, and are capable of reducing leakage through punctures.

Title: Forming uniform layer of fibrous material - on conveyor in distribution chamber by conditioning carrier and control air streams and passing through layer
Inventor: ROSBY SVEN-OLOV
IPC: D04H1/04
Filed: 1978-03-21
Abstract: In the parent patent, wood chips carried by an air stream are deposited in a uniform layer on a conveyor passing through a distribution chamber by controlling the deposition with the aid of two oppositely directed air streams whose flow rate is varied. In the course of deposition the drying, wetting and cooling steps are carried out separately or in dependence on one another. In this addn., wood chips-carrying air stream or the control air streams are conditioned prior to entry into the distribution chamber so that they are suitable for the carrying out of the predetermined course of the process and the wood chips are subjected to violent turbulence by the control air streams on arrival in the distribution chamber. Carrier air stream and the control streams are forced through the layer during removal from the chamber for further treatment of the deposited wood chips layer. Field of application of process is increased.

Title: Plastics drainage moulds for soft cheese - have sidewall and bottom slits joining outside surface channels
Inventor: HAEUFGLOECKNER HELMUT
IPC: A01J25/13
Filed: 1979-03-14
Abstract: Slitform drainage openings in the side walls and bottom together with straight vertical recesses forming drainage channels, in the outer side walls, are provided in moulds of synthetic material for the production of soft cheeses.

Title: Cybernetics information system for taxi drivers - gives visual communication to taxis as to demand and has one taxi as observation taxi
Inventor: MUELLER-SCHOENAU ANDREAS
IPC: G08G1/123
Filed: 1979-04-20
Abstract: The demand for taxis is communicated to passing drivers at certain locations visually. The necessary information is provided by the drivers themselves and supplements the present system of radio communication. One driver is allocated the function of input i.e. observation and another taxi has the output function which consists in flashing the right indicator light. The observation taxi is parked so that its driver has a good view of the pick up area. He knows the minimum and maximum number of taxis required and reports to headquarters, who, in turn, instruct the "indicator" taxi who is parked on the pick up site to flash his lights if the demand for taxis exceeds the supply and passing taxis respond accordingly. The two drivers are volunteers and are entitled to clock the time, 30 minutes during which they are on duty. A possible application would be at a major international airport.

Title: Space heater for heavy land vehicle or boat - uses lubricating oil as heat source with additional power input in heater feed line
Inventor: HOYER MANFRED DIPL ING
IPC: B60H1/22
Filed: 1979-04-26
Abstract: The heater is partic. envisaged for use in earth moving vehicles or large agricultural tractors, and is intended for warming the driving cab. In order that the temp. of the lubricating oil flowing in the heater feed can be raised quickly following a cold start an additional heat source is connected in series. This source is pref. a small eddy current brake, driven by the engine, the losses of which are transferred to the oil. Alternatively hydromechanical power can be employed to apply friction energy into the oil. In a typical installation a portion of the engine lubricating oil is transmitted from the oil pump through feed pipes to a heat exchanger in the cab. A return line discharges the cooled oil into the sump. The eddy current device, or its equivalent, is connected into the feed line the oil picking up the heat generated by the device.
