Title: Method for the production of an edge protector for a sheet-metal coil
Inventor: KUNZ DIETER DIPL ING
IPC: B21D11/08
Filed: 1984-10-03
Abstract: A description is given of a method for the production of a sheet-metal edge protector for a sheet-metal coil. The edge protector consists of an inner ring and an outer ring, possibly with a sheet-metal disc between the two rings. The inner ring rests against the inner front edge of the sheet-metal coil and the outer ring rests against the outer front edge of the sheet-metal coil. Both rings have an L-shaped profile. According to the invention, the end flange of the inner ring is cold formed at a multiplicity of mutually spaced points in regions widening radially outwards. The inner ring is thereby provided with its desired shape without the risk of the end flange of the inner ring tearing.

Title: Process for removing nitrate from water
Inventor: WOLTERS NORBERT PROF DR RER NA
IPC: C02F3/34
Filed: 1984-11-07
Abstract: By bacterial reduction of the nitrate to nitrogen, the nitrate is removed from the water which is essentially free of carbon-containing compounds. The water, in a treatment zone, is brought into contact with a bacteria-carrying solid support, which itself is brought into contact with a carbon-containing substance. The carbon-containing substance used is a natural oil and/or natural fat and the solid support used is fine particulate alkaline earth metal-containing minerals. The carbon-containing substance preferably added to the water is edible oil or edible fat. The fine particulate solid support used can be calcium carbonate, magnesium carbonate, limestone or dolomite. The fine particulate solid support reacts with the natural oil or fat in water at least partially forming soap. A slurry which contains the fine particulate solid support and alkaline earth metal soap is preferably mixed with natural oil or fat outside the treatment zone and passed into the treatment zone. Per kg of nitrogen removed, about 0.8 to 1.5 kg of natural oil or fat is entered into the treatment zone.

Patent DE-3445042-A1 (DE)
Title: Power transmission for pedal cycles with wheels aligned in a single track
Inventor: HARTMANN FRIEDRICH
IPC: B62M9/02
Filed: 1984-12-11
Abstract: The use of toothed belts for pedal cycles instead of the conventional roller chains is advantageous per se. Militating against this is, however, the difficult mounting thereof, which requires a dividing gap to be made in the frame or in the rear wheel fork so that the belts, which are always made in the form of endless loops, can be put on. The invention circumvents these difficulties by introducing an intermediate gear which spans the rigid fork, is in direction engagement, outside the fork, with the toothed belt and is coupled, within the fork, to the gear wheel of the rear wheel.

Filed: 1984-12-14
Abstract: To lubricate a shaft (14) which may be incorporated inside a bearing block, a bearing ring (40) is supported inside the block and has an internal groove housing an oil ring (19). The oil ring dips into an oil reservoir at low level, and distributes oil around the shaft as it rotates. Connected between the bearing ring and the oil ring is a strip (42) of tapered shape which assists separation  of the oil from the oil ring. The narrow end of the strip is at the top, entering a channel (24) on the underside of the oil ring. The wide end is flanged,  projecting outwards for connection with the inside of the bearing  ring. The strip follows the curvature of the shaft.

Patent DE-3503549-A1 (DE)
Title: Goal with changing set targets
Inventor: HORVATH VIKTOR
IPC: A63B63/06
Filed: 1985-02-02
Abstract: The invention relates to a goal with changing set targets for the purposes of sport, leisure activities, fitness training and entertainment. The actions are spontaneously transmitted in the absence of a physical component. The constantly changing set targets reproduce the multifarious aspect of a ball game in the goal area. The set targets are moved by the force of impact of the ball on rotary bodies inter alia (Figures 1, 2). The offset arrangement of set targets increases the confrontational nature of the game, as goal opportunities are mutually exclusive. They must be first realised. The movement of set targets may also be generated by computer-controlled transmission of signals, i.e. without physical movement. A pendulum with an electromagnet blocks the target aperture or releases it. Whole sequences of movements (goalkeeping) can be reproduced if the process is coupled with coloured signal lights (Figures 8, 9). The set targets can also be moved via a motor drive. <IMAGE>
Patent DE-3532204-A1 (DE)
Title: Corrosion protection for tension members consisting of wire ropes, comprising parallel-wire and parallel-strand bundles
Inventor: BORELLY WOLFGANG DIPL ING
IPC: E04C5/01
Filed: 1985-09-10
Abstract: Proceeding from the fact that corrosion protection for factory-made parallel-wire and parallel-strand bundles as tension members for receiving high loads is difficult to provide in some sectors of use and, in the choice of plastic coatings, is generally unsatisfactory in its effectiveness in respect of long-term weather resistance, the method of cladding the tension members with a high-alloy and therefore non-rusting thin sheet-metal sheath and of filling the annular gap to be provided with a mineral oil having an anti-corrosive effect is proposed. According to the invention, this method is particularly suitable for renovating the defective corrosion protection of already assembled tension members which have been in use for some time. The low-viscosity oil, together with the outer sheet-metal sheath, completely separates the newly enclosed tension member requiring renovation from the external aggressive media of the atmosphere. It penetrates into the smallest cavities of the rope assembly and of the parallel-wire and parallel-strand bundles and there reliably prevents corrosion processes which have possibly already occurred, this being particularly important especially for the places which are inaccessible and which cannot be checked. The low care requirement, the long lifetime and the automatic tightness check which can thus be achieved at the same time are further benefits of the invention.

Title: Pneumatic actuator for an exhaust gas throttle
Inventor: GRUNDMANN EDGARD DIPL ING
IPC: B60H1/18
Filed: 1986-01-07
Abstract: For the movement of an exhaust gas throttle (5) provided in the exhaust gas system (6) to increase the utilisation of the energy loss of the combustion engine (7), a control unit (1) is provided between actuation rod parts (3, 4) succeeding one another with an axial spacing and contains, as essential components, two diaphragms (15, 16) which delimit a pressure chamber (12, 14) in each case, one (12) of which can be subjected to the exhaust gas counterpressure upstream of the exhaust gas throttle (5) and the other (14) of which can be subjected to subatmospheric pressure. The subjecting to subatmospheric pressure acts so as to cause a length change of the actuation rod (2) so as to effect a closing movement of the exhaust gas throttle (5), whereas the attainment of a value, predetermined by a counterspring (17), of the exhaust gas counterpressure leads to a change of the entire length of the actuation rod (2) in the opposite direction, which results in an opening movement of the exhaust gas throttle (5) (Fig. 1). <IMAGE>
