Patent DE-3123274-A1 (DE)
Title: Toothed clutch
Inventor: HANEKLAUS KARL
IPC: F16D3/18
Filed: 1981-06-12
Abstract: To lubricate the teeth of toothed clutches, the clutch housing must be filled with oil or grease. Due to the play between the feather or key and the hub, the lubricant can escape from the inside outwards, especially when high centrifugal forces occur. For the purpose of sealing, the inner hub faces have hitherto been sealed off with the aid of hub caps or inner closing plates. However, this solution has not proven satisfactory since, due to the thinness of their walls, hub caps frequently come loose by themselves, are in some cases pressed on askew upon assembly or are lost during transport. The manufacture of hub caps or inner closing plates is expensive. Also known is sealing by caulking the grooves internally or externally with lead, giving rise to considerable costs. To avoid these disadvantages, the toothed clutches are, according to the invention, provided with thin, tear-resistant films on their inner hub faces and shaft ends. Completely satisfactory sealing is thereby possible for a minimum expenditure of work both with new clutches and clutches already in operation.
Patent DE-3126829-A1 (DE)
Title: Process for generating an inert gas containing CO2 and N2 for the protection of flammable dusts by combustion of carbon-containing fuels with air, and inert gas generator for carrying out the process
Inventor: HANNES KLAUS DR ING
IPC: B01J19/14
Filed: 1981-07-08
Abstract: Shutdown inertising of grinding installations, silo installations and conveying devices or the like for flammable dust is carried out by employing inert gases. It is known to generate an inert gas containing CO2 and N2 by combustion of carbon-containing fuels with air, oil or gas being used as the fuel. This does, however, carry the risk of the inert gas containing too much water vapour. In order to provide an essentially water vapour-free inert gas it is proposed that coke be predried and burnt with air. If the process is carried out in this manner, a largely water vapour-free inert gas is achieved. The inert gas generator according to the invention has a furnace (1) for burning coke (K) upstream of which there is a pre-drying chamber (5) which can be charged with coke and can be subjected to the combustion heat. <IMAGE>

Title: Two-wheeled wheelchair
Inventor: BASTANI HESSARI NAVID
IPC: A61G5/00
Filed: 1981-06-12
Abstract: The invention is aimed at designing a wheelchair which can be produced economically and is capable, without any additional fittings, of driving on uneven ground, over steps and into a transporter without any danger to the driver's security. The two-wheeled wheelchair comprises two wheels fitted to the sides of the seat. Forward and backward movement takes place as a function of the weight and of the installation and shiftability of the total weight under the axletree. If required, the height of the seat can be adjusted, and this depends on the weight installed under the axletree. Special spokes permit better sight and contact to the outside. For moving over large steps or into a transporter an artificial step is produced by unfoldable supports. <IMAGE>

Patent DE-3136617-A1 (DE)
Title: Braking wheel slip control system for the wheel brakes of a vehicle
Inventor: KLEIN HANS-CHRISTOF
IPC: B60T8/34
Filed: 1981-09-15
Abstract: In a braking wheel slip control system (brake slip control system) for the wheel brakes of a vehicle at least one brake line (7) leading from the master cylinder is provided, which branches into at least two brake conduits (9a and 9b). A pressure reducing valve is located in the brake conduit 9b, so that a higher pressure is set in the brake conduit 9a. According to the invention the brake conduit 9a with the increased pressure is assigned to a vehicle wheel of the brake circuit most involved in the total braking effect. The pressure reducing valve (13) is designed so that the vehicle wheels assigned to the brake conduits (9a and 9b) normally attain critical slip values more or less simultaneously but the vehicle wheel of brake conduit 9a with the increased pressure (front wheel of a passenger motor vehicle) is exposed to the locking tendency first. In this way control valves in each of the brake conduits can be dispensed with. In a control sequence all vehicle wheels of brake conduits (9a and 9b) run more or less at their critical limit, so that in a common control of the brake conduits (9a, 9b) virtually no brake power losses have to be accepted. The control is conducted by the vehicle wheel of brake conduit 9a with the increased pressure, which is most involved in the total braking effect. The other wheel of the brake conduit (9b) with the reduced pressure (rear wheel of a passenger motor vehicle) transmits comparatively little brake power and can consequently be controlled without any problem simultaneously with the wheel of the brake conduit 9a even before critical slip values are attained. The resulting loss of total braking power is negligible and bears no relation to the saving on valves. The pressure reducing valve (13) of brake conduit 9b can be replaced by a pressure booster valve in brake conduit 9a. The arrangement according to the invention is especially suitable for a braking wheel slip control system, generally with dynamic actuation of the wheel brake cylinders. <IMAGE>

Title: Device for controlling the air-fuel ratio of the operating mixture to be introduced into the combustion chambers of a self-igniting internal combustion engine
Inventor: STRAUBEL MAX DR ING
IPC: F02M26/60
Filed: 1981-10-20
Abstract: A device is proposed in which the quantity of fuel fed in, the quantity of fresh air required for combustion of this quantity of fuel and the quantity of returned exhaust gas required for residual filling of the cylinder can be precisely determined by simple means. Firstly, orifice gauges (6, 7) are used for this purpose in the intake pipe (2) and in the fuel line (3), which is supplied by a fuel feed pump (8) at constant pressure, which orifice gauges control a valve (42), which adjusts the particular ratio required between the fresh air and the returned exhaust gas, by way of a four-chamber differential pressure valve (5). Secondly, pneumatic actuators are used for this purpose both for the fuel supply (56) and for the exhaust gas return (69), which are adjusted by means of a control logic (74) by way of electro-pneumatic control valves (58, 71) as a function of the fresh air feed (62). <IMAGE>

The invention can be advantageously used, particularly in a lye pump for washing or dishwashing machines. <IMAGE>
Patent DE-3143040-A1 (DE)
Title: Device for locking a pressure medium-actuated double-acting piston-cylinder drive
Inventor: FRANIA JOSEF
IPC: F15B15/26
Filed: 1981-10-30
Abstract: The invention relates to a device for locking a pressure medium-actuated double-acting piston-cylinder drive. A piston which separates two pressure-medium chambers from one another is guided in a sealed manner in a working cylinder and is used to drive a piston rod connected to the piston. The piston rod has a recess which is arranged perpendicularly to its longitudinal axis and has the function of a locking stop. The cylinder casing is provided with a stepped recess in which a stepped piston is guided in a manner which allows displacement counter to the force of a spring. The effective surfaces of the stepped piston delimit two chambers which are each connected to one of the two pressure-medium chambers via channels provided in the cylinder casing. The stepped piston is connected to a locking rod which is arranged axially parallel to the recess in the piston rod and can be brought into engagement with the recess. When supply pressure is present in one of the two pressure-medium chambers of the working cylinder, the stepped piston is pressurised by the pressure medium from the relevant pressure-medium chamber and the locking rod is in this way held in the unlocking position. If the pressure in the pressure-medium chambers falls below a predetermined value, the stepped piston and thus also the locking rod is pushed towards the piston rod by the force of the spring. The locking rod engages in the piston-rod recess serving as a locking stop and prevents a displacement of the piston until the pressure in one of the pressure-medium chambers rises again.

Title: Bowden cable window lifter, in particular for cars.
Inventor: JAKOB WILLI
IPC: E05F15/692
Filed: 1982-01-21
Abstract: A manually operated Bowden cable window lifter is described which can be converted into an electro motively operated lifter by attaching an electro motive drive component. For this purpose, the crank bolt is lengthened towards the rear and a worm gear can be plugged onto the extension in a positively locking manner. The worm gear intermeshes with a worm which is seated on the rotor axis of an electric motor which can be screwed for example onto the bar of the window lifter. The crank bolt can be displaced in the axial direction and, in addition to the worm gear bearing, has a free rotation element. If the crank bolt is displaced longitudinally, the free rotation element is pushed into the worm gear. The window lifter is then capable of emergency manual operation - when the worm gear is stationary.
Patent DE-3203598-A1 (DE)
Title: Multipurpose filler for air humidifiers and air purifiers
Inventor: TISCHENDORF JOACHIM PROF DR IN
IPC: F24F8/158
Filed: 1982-02-03
Abstract: Small air humidifiers have the disadvantage that they are ineffective when not refilled with water. Moreover, most evaporator mats give the air an unpleasant smell. According to the invention, these two disadvantages are avoided by using as filler an activated carbon fleece which frees the water intended for humidifying from smells so that the air loses the smell. The invention also envisages arranging a number of fleeces in a humidifier, one of which is operated in the wet state and the other in the dry state, so that additional smell cleaning of the air takes place during humidifying of the same. As the gaseous harmful substances take up the greatest part of the air in terms of weight and are the aromatic hydrocarbons which are most dangerous for causing cancer, the activated carbon fleece has an important cleaning function. If one forgets to refill an air humidifier with water, it then at least has the function of an air purifier.

Title: Feeler rod measuring device having a digital display unit
Inventor: ROETH RUDOLF
IPC: G01B11/02
Filed: 1982-03-26
Abstract: The invention relates to a feeler rod measuring device having a housing and a digital display unit. The measuring device has a feeler rod and a feeler element, which can be likewise designed as a feeler rod, as well as two measuring rods, which can be driven by said feeler rods and are provided with linear arrays. In conjunction with sensor devices, the measuring rods generate electrical pulse trains which correspond to the movement of the linear array. The two pulse trains are connected to one and the same signal processing device, in which they are added or subtracted taking account of their sign. An exceptionally shortened design of the measuring device is achieved due to the division of the entire measurement range between two measuring rods and by the possibility that the measuring rods can be moved past parallel to one another. The invention further relates to a signal processing device having supplementary devices which expand the function of the measuring device. <IMAGE>
