Patent DE-3312341-A1 (DE)
Title: Device for increasing the power of internal combustion engines
Inventor: HENTSCHEL ROBERT
IPC: F02M25/00
Filed: 1983-04-06
Abstract: The invention relates to a device for increasing the power of internal combustion engines in which, according to the invention at least two additional nozzles are provided between the carburettor and the combustion chamber, which nozzles are arranged in the mixture intake flow in the intake manifold between the carburettor chamber and the carburettor or in passages in a flange, arrangable between the carburettor and the intake manifold or the intake manifold and the combustion chamber, and designed as openings of tubular parts extending into the mixture intake flow or passing through this, which are closed on one side, for the injection of additional petrol and an additional gas, for example N2O (laughing gas), which with the motor produces an explosive mixture in the internal combustion engine. The outcome of this is that additional petrol and at the same time also a gas can be injected into the petrol-air mixture produced in the carburettor, which results in an additional energy mixture, so that more fuel can burn and explode in the internal combustion engine and therefore more power is delivered.
Patent DE-3312944-A1 (DE)
Title: Stress-relaxed metal support housing for exhaust gas catalysts having high thermal operating load
Inventor: CYRON THEO DIPL ING
IPC: F01N3/28
Filed: 1983-04-11
Abstract: The present invention relates to a metal support housing for exhaust gas catalysts, comprising spirally wound, alternatingly layered smooth (1) and corrugated (2) metal strips which are attached by a jointing method in a pipe casing, a large number of support matrix cells (10) being formed, open in the longitudinal direction. The design according to the invention is to trap alternating expansions by elastic deformation and thus increase the life by avoidance of crack formation. For this purpose, it is proposed that the corrugated (2) and the smooth (1) metal strips are only joined at certain parts of the contact sites by a jointing method, that is in such a manner that the distances between the sites joined by a jointing method allow thermal expansion of the support matrix without plastic alternating deformations. For this purpose, in particular the majority by far of the matrix cells (10) should have in each case at most one joint (either 3 or 4) to one of the two neighbouring metal strips. An arrangement of the sites joined by the jointing method alternating both in radial and axial aspect is particularly proposed.   <IMAGE>

Patent DE-3326755-A1 (DE)
Title: Passage for people
Inventor: EBERLEIN HERBERT DIPL ING
IPC: E06B11/08
Filed: 1983-07-25
Abstract: Passages for people, which are located in self-service shops, generally consist of a turnstile and fences which adjoin to the right and to the left of the turnstile. In this connection, it continues to happen that children, who fiddle about in a playful manner on the turnstile, are caught between the turnstile and the fences. It is true that passages for people are now equipped with safety devices which make it possible either to turn the turnstile backwards or to remove the turnstile head, but apparently these devices are not always adequate. The invention therefore proposes a passage for people (1), in which not only the turnstile (2) is equipped with safety devices but in which parts of the fences (8, 15) are also provided so that they can be moved away from the turnstile (2). A person who is caught can thus be freed from being caught much more simply and without danger. <IMAGE>

Patent DE-3403694-A1 (DE)
Title: Chemical process for water softening
Inventor: FRANK PETER
IPC: C02F5/08
Filed: 1984-02-03
Abstract: The process for softening calcium salt- and magnesium salt-containing river and spring water using isopolyanions of silicic acid has been particularly developed with regard to environmental acceptability. The phosphates currently used for softening in most detergents are an exceedingly high pollution for our bodies of water, because they lead to an overfertilisation of the water. Aquatic plants, in particular algae, proliferate uncontrollably as a result and can cause a so-called "collapse" of the water bodies. The softening is performed by the novel process by complex formation, as with the phosphates, no precipitate/residue is thus formed which could pose problems. Since the action is initiated immediately, it is again possible, in particular, to wash without problems using soaps made of natural fats/vegetable oils, since the hitherto restrictive formation of insoluble calcium soaps is prevented. Specifically, aqueous solutions of water glass (already long known, for example, for egg preserving) can be used, since they contain large amounts of these polyanions and are easily available in relatively large quantities.

Patent DE-3414107-A1 (DE)
Title: Variable-speed spur-gear transmission shiftable under load
Inventor: FRANKE RUDOLF PROF DR ING
IPC: F16H3/00
Filed: 1984-04-13
Abstract: The invention relates to a new type of variable speed transmission, especially advantageous for agricultural tractors and commercial vehicles, which comprises a combination of a full synchromesh basic transmission (3) with a double clutch (2) and a plurality of gears, shiftable under load, with an auxiliary transmission (4) on the output side with three forwards and one reverse ranges. An essential simplification of the operation is achieved in that the driver shifts the gears of the basic transmission (3) in stages under load by means of the clutch pedal. By means of the manual shift lever of the auxiliary transmission, which is appropriately mounted on the steering wheel, he merely engages another range, thereby declutching and at the same time automatically shifting the suitable gear of the basic transmission (3), so that a continuous series of twelve speeds is obtained with an approximately equal and finely graduated progressive ratio. A considerable reduction of the manufacturing costs is achieved in that only two friction clutches are required which have only to transmit the single engine torque and are accommodated in the flywheel of the engine without taking up additional space; in that individual gear pairs are repeatedly used in different gears, so that compared to the number of shift stages a minimum number of gear wheels and shift positions is achieved. <IMAGE>

Title: Vacuum cleaner nozzle with suction tube connection, sliding sole and rotating brush cylinder
Inventor: OBBELODE WILFRIED
IPC: A47L9/04
Filed: 1984-04-19
Abstract: In a vacuum cleaner nozzle with a suction tube connection, sliding sole and rotating brush cylinder and with a turbine wheel, to which the suction air flow is admitted via a suction channel, as the drive for the brush cylinder, a control device in the manner of a nozzle for conducting the suction air flow is arranged in the suction channel of the turbine wheel and can be switched on and off via a foot switch arranged on the vacuum cleaner nozzle. Depending on the switch position of the control device, the suction air flow for the turbine wheel is passed over the turbine wheel either in a non-conducted or concentrated manner. It is thus achieved that, on the one hand, the turbine wheel or the brush cylinder rotates with reduced performance and, on the other hand, with full performance without the suction performance dropping at the nozzle.

Title: Method for quality control in ultrasonic welding and associated apparatus
Inventor: MOLL HELMUT
IPC: B29C65/00
Filed: 1984-08-13
Abstract: In ultrasonic welding, it is known to detect significant welding parameters and compare them with adjustable lower and upper tolerance values. It has already been proposed to regulate the welding energy by varying the power time or welding time. Now, during the welding operation, particularly the power trend (P(t)) or the energy (@P(t)dt) determinable from this are compared in segments by reference to a predeterminable desired curve for correspondence to tolerance ranges which can be predetermined differently from segment to segment. In the associated apparatus, the switching units assigned to the ultrasonic generator have at least threshold elements or comparators; their function can also be performed in software terms by an existing microprocessor system. By means of the processor system proposed, the quality control in ultrasonic welding can be improved. <IMAGE>
