Patent DE-3810614-A1 (DE)
Title: Dispensing device for two-component knifing filler
Inventor: GIEBL ULRICH
IPC: B05C17/005
Filed: 1988-03-29
Abstract: Known devices of this type are of a construction which is susceptible to faults and expensive, which makes intensive maintenance necessary. Furthermore, after completion of the apportioning operation, two-component knifing filler continues to be issued from the containers or from the device, so that there is soiling, which may lead to failure of the device. The novel device is to be inexpensive to produce, unsusceptible to faults and operable with one hand. Furthermore, it is to be distinguished by high operational reliability, low operating costs and unintensive maintenance. To provide a device of the type mentioned at the beginning by which the object mentioned above is achieved, it has a means of propulsion which is connected to a means closing of the discharge opening of the cartridges for opening of the same during an advancing movement of the pushrod and which is provided with an uncoupling means limiting the propulsion. The device is suitable for receiving containers with contents to be apportioned, in particular for receiving cartridges with two-component knifing filler to be apportioned.

Title: Method for the analytical determination of acetylcyanamide
Inventor: RUST ULRICH DR
IPC: G01N30/46
Filed: 1988-08-12
Abstract: To determine acetylcyanamide in aqueous solutions of biological materials, the solutions are made alkaline, purified with activated carbon, optionally acidified by addition of a mineral acid, acetylcyanamide is extracted from the aqueous phase using a water-insoluble extractant and extracted from the latter using dilute aqueous alkali. Acetylcyanamide is separated off by high-resolution liquid chromatography and determined spectrophotometrically. The analytical method is highly specific and is suitable for the trace determination of acetylcyanamide, in particular to determine the metabolism of cyanamide in human and animal metabolites (metabolic products) and in plant, animal and human body tissues.

Title: Interface arrangement for a bus system
Inventor: HEICHLER JOHANNES DIPL ING
IPC: H04L12/40
Filed: 1988-10-18
Abstract: Users such as data transmitters and data receivers can be connected to one another via a common bus.

Each driver (T1, T2) is provided with a hysteresis circuit consisting of a voltage divider (R21, R31; R22, R32) for restoring the direct-voltage value. Due to the measures of the invention, there is no bus blockage due to component failures, particularly short circuits. <IMAGE>
Patent DE-3837776-A1 (DE)
Title: Force measuring spring of low constructional height
Inventor: HORN KLAUS PROF DR ING
IPC: G01L1/22
Filed: 1988-11-08
Abstract: A spring body is described for force measuring cells, weighing cells and similar force pick-ups, which spring body works preferably according to the strain gauge principle and on which either bending extensions or shear extensions are picked off. The spring body invented is distinguished in that, for a measuring spring, it has a bending beam which merges at its ends into load input angles and load output angles, which are designed as partial angle elements, shaped as a pair in a mirror image to the longitudinal axis of the bending beam, which are, furthermore, arranged inserted into each other in a plane at right angles to the measuring force direction. The spring bodies are simple to produce and can be produced integrally by machining out dividing slits and bounding slits from a metal sheet. They can, however, also be cut off as discs (plates) from correspondingly preformed, extruded material. When using hollow bodies as bending beams, the strain gauges used can be applied on the inner walls of the hollow body. The hollow body can be hermetically sealed with respect to the external atmosphere by means of sealing stoppers, and overload safety devices can be fitted in a simple way in the form of locating pins which run in concentric locating holes in each case through neighbouring load angle elements, in one element of which they are fixed firmly with a press (force) fit, while they have a play in the other element which corresponds to the permissible spring travel.

Title: Device for the infinitely variable adjustment of the preload of the double nut of a screw drive, particularly a ball screw
Inventor: GRUETTNER ULRICH
IPC: F16H25/22
Filed: 1989-01-26
Abstract: In a preloading device for the double nut of a ball screw, the aim is, by means of adjusting and operating elements, to rotate one nut relative to the counternut until the recirculating ball race on both sides has a desired freedom from play. In order to ensure that tightening is particularly simple and reliable, the proposal is to make a sliding key displaceable to a defined degree in an axially parallel sliding guide in one nut, the sloping surface of the key driving onto a run-up slope on the counternut.

Title: Method and apparatus for operating a diesel engine with a particulate filter for cleaning the exhaust gas
Inventor: BOLL WOLF DR ING
IPC: F01N3/023
Filed: 1989-02-14
Abstract: In diesel engines with a particulate filter for cleaning the exhaust gas, in which the particulates removed from the exhaust gas are burnt on the filter, the temperatures available in the part-load range are frequently too low for combustion of the particulates. As a temperature-increasing measure, which may be combined with other measures known per se, the proposal is to throttle the engine cooling as partial load decreases, although only up to a predeterminable lower part-load value, below which the system is in any case no longer capable of burning particulates. Throttling can be performed in such a way that it is reduced if there is a sudden transition from full load to a low-load range with a simultaneously high engine speed.

Filed: 1989-05-09
Abstract: The description relates to a worm drive metering device for fluid material in which a blocking device is arranged at the lower end of the metering pipe (5) designed to prevent material from leaking from the metering pipe when the worm drive in it is stationary. This blocking device consists of a fine-pored, gas-permeable, preferably cylindrical barrel (9) with an inside diameter substantially corresponding to that of the pipe (5) which joins the outlet end of the pipe (5) and is surrounded on the outside by a housing (11) forming with the barrel (9) an annular chamber (16) into which opens a suction connector (17). During operation, the chamber (16) is subject to underpressure when the worm drive (16) is stationary or running so that the air in the material to be metered is removed in the region of the barrel, so that, in turn, when the worm drive is stationary, the material clings together in the barrel and leakage is thus prevented.

Title: Motor vehicle brake - has roller to drive an air compressor in order to store energy for braking
Inventor: GENC MEVLUT
IPC: F03G7/08

Abstract: The vehicle brake uses some of the energy which is normally dissipated in heat. The system has a roller, which is covered with friction material and pressed against the brake disc or brake drum of the vehicle so that the roller is caused to rotate. The roller is connected to an air compressor which delivers compressed air to a storage vessel. The vehicle has a second brake disc or brake drum which is mounted on the side of the roller opposite to the first brake disc or drum. Additional pressure on the brake pedal brings the roller into contact with the second brake disc or drum so that the brake functions as a normal friction brake. This second brake disc or drum is used for emergency braking.

IPC: B60T8/66
Filed: 1990-03-22
Abstract: The invention relates to an antilock braking system (ABS) for all-wheel drive vehicles in which, in particular, a reference speed for slip control is formed. An auxiliary reference and a reference speed for the slip control are derived from the speeds of wheels with different speeds. In the event of instability, however, the increase in the auxiliary reference determines the variation in the reference speed.
