Title: Rear axle drive, especially for motor vehicles, with a differential gear and an infinitely variable speed transmission
Inventor: GAUS HERMANN
IPC: B60K17/16
Filed: 1983-05-28
Abstract: In the case of a rear axle drive an input shaft is connected by an infinitely variable speed transmission to an intermediate shaft having a drive bevel gear pinion. The drive bevel gear pinion meshes with a ring gear of a differential gear, which is connected to two universal joints lying symmetrically in relation to a vertical reference plane. The transmission housing is divided by a partition wall running transversely to the vertical reference plane into two transmission chambers, one of which accommodates the differential gear and the other the variable speed transmission with input shaft and intermediate shaft lying parallel to the vertical reference plane in each case. For a compact design of the rear axle drive the partition wall is arranged in front of a transmission main axis perpendicular to the reference plane and the differential gear in the rear transmission chamber. The front transmission chamber accommodates the variable speed transmission with input shaft and intermediate shaft. The axis of rotation of the input shaft lies in the vertical reference plane. The axis of rotation of the intermediate shaft is closer to a joint plane, which contains the joint centre lying on the same side of the reference plane and lies parallel to the reference plane, than to the reference plane.

Patent DE-3323154-A1 (DE)
Inventor: MARKERT HELMUT DIPL CHEM DR
IPC: H01F41/12
Filed: 1983-06-27
Abstract: The invention relates to a method for impregnating and embedding electrical windings, especially coils of transformers, by means of an impregnating or casting resin based upon polyepoxide-polyisocyanate mixtures in the presence of a reaction accelerator latent at the processing conditions, which employs conditions that prevent the formation of gas and shrinkage voids in the cast in winding. To this end, the resin including, if applicable, additives, is dried at reduced pressure and while stirring at temperatures of up to 110 DEG C. and the winding is cast-in with the dried resin at reduced pressure and at temperature of up to 110 DEG  C.; then the reduced pressure is removed and the winding is exposed to overpressure. Subsequently, generating by an elevated temperature in the electrical winding by Joule heat in the conductor, the cross-linking reaction of the resin is started and is controlled as a function of the reaction heat, until the winding is removed from the mold and post-hardened.

Title: Process for producing integrated, lightweight solid constructions which aid redevelopment
Inventor: SCHRAMM HORST DIPL PHYS
IPC: E04B1/92
Filed: 1984-03-17
Abstract: A process is described by which houses can be constructed which are much cheaper with regard to both construction costs and supply costs. The houses comply with the current regulations of construction engineering and they are above-average in terms of statics, fire protection and sound insulation. Self-sufficiency can be achieved where power supply, water supply and drainage, and vegetable-growing are concerned. In specific embodiments, the houses can create their own plot of land and contribute to urban redevelopment by building over streets and industrial sites. The building processes are designed so that a high proportion of self-involvement is possible. In the case of an average proportion of self-involvement, costs can be reduced such that savings on supply costs are sufficient to finance the remaining construction costs. In economic terms, the construction therefore costs nothing.

Title: Process for evaporating liquids under vacuum and apparatus for carrying out the process
Inventor: HUBER PETER
IPC: B01D3/42
Filed: 1984-04-10
Abstract: An apparatus (1) (Figure 1) serves for evaporating liquids under vacuum. For the accurate pressure assignment at a given temperature for boiling a liquid, an evaluation and control device (11) is provided, by means of which, via a pressure sensor (10), the pressure change per unit of time (rate of change of pressure (dp)/dt) during exhaustion by a vacuum pump can be determined. When the pressure curve approaches the boiling line roughly asymptotically, the rate of change of pressure changes accordingly and when a set value is reached, the vacuum pump (5) is shut off. By determining the differential quotient and comparison with a limit value, for any desired solvent or solvent mixture and any desired temperatures, exhaustion can always be carried out using the vacuum pump (5) near enough to the optimal boiling pressure in each case, without a significant loss of solvent having to be accepted. <IMAGE>

Patent DE-3427902-A1 (DE)
Title: Control of hydropneumatic suspension elements, especially for motor vehicles
Inventor: TUCZEK FRANZ DR ING
IPC: F16F9/06
Filed: 1984-07-28
Abstract: In the suspension element a gas cushion separated from a volume of oil by a movable partition wall generates spring forces of an oil displacing spring piston. In the event of load variations, control devices fixed to the partition wall cause the partition wall to be guided into the centre position by feeding gas from a high pressure vessel or gas discharges into a low pressure vessel. The special characteristics include: constant gas volume for load-adjusted gas pressure, constant vehicle level without external filling control unit, load-proportional spring rate due to low resistance gas flow, possible body righting when cornering, possible level adjustment by topping up or draining off oil in a workshop. For stabilised suspensions, in which two suspension elements, each with a gas cushion are also connected on the oil side to a stepped piston loaded by a third, common gas cushion and level control is by means of filling governors by feeding gas from the high pressure vessel into the common gas cushion or gas discharges from the common gas cushion into the low pressure vessel, special characteristics include: constant gas volumes of all three gas cushions for load-adjusted gas pressure, load-proportional spring rates for spring movements in the same and opposite directions, possible body righting when cornering.

Patent DE-3435864-A1 (DE)
Inventor: BRAEUNINGER JUERGEN
IPC: B60T8/00
Filed: 1984-09-29
Abstract: To reduce the transmission requirement of transmitting data between brake controlled microprocessors (7, 8, 9; 20-25) and a reference microprocessor, or reference microprocessor section (15) within one of the wheel speed microprocessors, the microprocessors are connected in a ring connection, or ring bus (13; 26, 27). The microprocessors generate, in each processing cycle, a code number based on the then pertaining operating conditions of the wheel or axle with which the respective microprocessor is associated. A code number determines one of several slopes for changing the reference signal. The code numbers are applied to the ring connection and thus to the reference microprocessor, where they are compared with stored code numbers, in which the stored code numbers are arranged in a predetermined priority sequence. Dependant on this comparison, a new reference signal is then generated which is transmitted to the microprocessors over the ring connection or ring bus for use as a reference value in calculating possible positive or negative slip of an associated wheel or the wheels of an associated axle. The system is particularly simple to check since transmitted code numbers, being recirculated in the ring connection, can be compared with previously transmitted code numbers.
