Patent DE-3433934-A1 (DE)
Title: Valve spring for lifting valves in reciprocating piston internal combustion engines
Inventor: GAEDE GEORG
IPC: F01L1/46
Filed: 1984-09-15
Abstract: In order to reduce sympathetic vibrations in valve drives in reciprocating piston internal combustion engines it is proposed according to the invention to provide a serial mounting of two springs, the known valve spring (3) having a greater stiffness than the second spring connected in series. The result of this is that the overall spring natural frequency exhibits an incremental behaviour, depending on the valve lift, so that sympathetic vibrations are reduced. By selecting suitable, self-damping springs even the vibrations occurring can be additionally damped. <IMAGE>

Title: Process for the hot desulphurisation of gases
Inventor: SCHWERDTFEGER KLAUS PROF DR IN
IPC: C01B3/56
Filed: 1984-09-20
Abstract: The invention relates to a process for the hot desulphurisation of reducing gases using copper which reacts with the sulphur contained in the gas to form copper sulphide and is then regenerated to form copper oxide or copper. In order, in a process of this type, to achieve a uniform reactivity of the desulphurisation agent over a large number of sulphurisation and regeneration cycles with the fullest possible utilisation of the desulphurisation agent offered, the invention proposes that porous desulphurisation bodies are used which contain finely divided copper granules separated from each other, whose diameter is smaller than the critical diameter during the desulphurisation for the formation of Cu2S shells. Preferably, the copper granules in the desulphurisation body have a diameter of less than than 500 mesh. Their concentration in the desulphurisation body is 1-35% by weight.

Patent DE-3523529-A1 (DE)
IPC: H02P27/02
Filed: 1985-07-01
Abstract: A method and a device for reducing the iron and copper losses of an induction motor (1). Such a motor comprises stator windings (2, 3, 4) connected by at least one solid-state switch (8, 9, 10) to a voltage source (12). The motor (1) comprises a rotor (19) connected to a load (20). The closing time of the solid-state switch (8, 9, 10) is modified as a function of the resistance torque exerted on the rotor (19). After ignition of the solid-state switch (8, 9, 10), the stator current is measured and compared with a current value which corresponds to the no-load current for each ignition angle. The load current is then determined on the basis of the total current and the no-load current. Finally, the ignition angle is modified by reducing the total current, while maintaining a load current sufficient to actuate the load (20).

Title: Processing and assembly installation
Inventor: STANKOWSKI BERNHARD DIPL ING
IPC: B25B23/10
Filed: 1985-08-23
Abstract: In a processing installation with a robot, the arm of the latter does not have all the drive and supply devices which are required for operating complicated tools, instead these tools are for their part combined with the entire drive and part of the robot intelligence to form their own tool heads. At least some of the tool heads preferably have magazines, which bring components into position for assembly and consequently dispense with the need to swivel the robot arm over great distances for gripping in each case a new component. A tool head for screwing a stud bolt into a threaded bore and a further tool head for screwing a screw nut onto a threaded bolt are preferred.

Patent DE-3539030-A1 (DE)
Inventor: CHROMY FRANZ
IPC: B25D17/06
Filed: 1985-11-02
Abstract: A hammer drill has a cylinder within a housing with the cylinder forming a piston chamber. A drive piston is reciprocally mounted within the piston chamber and is displaced by a motor. A percussion piston is located within the piston chamber with an air cushion space located between the two pistons. As the drive piston reciprocates, it moves the percussion piston back and forth by way of the air cushion located between them. One of the pistons has a conduit open at one end to the air cushion space and at the other end to the exterior of the cylinder. A closure plug is located in the one end of the conduit and closes off air flow from the air cushion space into the conduit at regular operating temperatures. If the temperature in the air cushion space rises due to air leakage from the space, the closure plug melts and connects the conduit with the air space so that the reciprocation of the percussion piston stops before the pistons strike against one another and cause damage.

Title: Method for the treatment of surfaces infested with bacteria and/or fungi, with a downstream hot-chamber arrangement
Inventor: HOELTER HEINZ DIPL ING
IPC: A61L2/07
Filed: 1986-03-13
Abstract: It is known that bacteria, viruses, fungi and the like often become established on porous surfaces, lining tiles, in wood and/or also in joints and wall coverings of rooms. Neither chemical combatting agents nor germicidal radiations nor treatment with vacuum cleaner devices have produced the desired success. To eliminate these parasites (pests), it is proposed according to the invention that a vacuum generator (4) with a suction nozzle sucks in the parasites on surfaces and supplies them to a hot-jet chamber (2) which has a temperature of preferably greater than 1500 DEG C, and the heated exhaust air is supplied via an insulated exhaust-air pipe (7) to a hot-gas filter (10), and above the hot-gas filter (10) there is attached an exhaust air mixing injector (8) which cools the exhaust air with secondary air and delivers it, free from germs, to the room in which the apparatus is located. The jet chamber (2) is coupled to a steam-generating system (3). Hot steam is delivered at the sucking-in mouth via a steam hose (6) in the suction hose (5) (Fig.).   <IMAGE>

Title: Device for preventing a rolling shutter door from dropping down
Inventor: HOERMANN STEPHAN DIPL PHYS
IPC: E06B9/84
Filed: 1986-07-03
Abstract: The device of the invention is used for a rolling shutter door 6 or the like in order to act on a motor-driven winding shaft 5. Provision is made of a dynamically self-locking worm 8 which is driven by a servomotor 17, has a meshing worm wheel 7 and is fixed, such that it cannot rotate, on the axis of the winding shaft 5 for the rolling shutter door 6. The worm 8 can be displaced, in at least one direction 14 along its spindle 9, as far as a stop 15 and is driven in a controlled manner by a servomotor 17 via a control means 18, such that it is itself turned back by the amount by which it would be displaced by the worm wheel in the direction of the spindle 9. When the rolling shutter door drops down, the worm 8, however, is pushed by the worm wheel 7 onto the stop 15 and, when said stop is reached, the worm wheel 7 is held owing to the dynamic self-locking with the worm 8, as a result of which the dropping-down movement of the rolling shutter door 6 is terminated. <IMAGE>
