Title: Oscillating wiper device (pendulum-type wiper device) for windows of motor vehicles
Inventor: ARTMANN JOACHIM DIPL PHYS DR
IPC: B60S1/18
Filed: 1988-02-11
Abstract: An oscillating wiper device is proposed which serves for cleaning windows on motor vehicles. The oscillating wiper device comprises an element which is driven in a revolving manner and holds one end of a connecting rod which is coupled by its other end to a rocker which, for its part, is connected fixedly to an oscillating shaft which bears the wiper and is mounted fixed to the frame. In order to obtain a particularly quiet, rattle-free running of the wiper blades resting on the window to be wiped, even in problematic window zones, the revolving element has a curved path which runs in an annular manner and surrounds its axis of rotation, the connecting rod being provided at its end held on the element with a rolling member rolling along the curved path, and furthermore means being provided which hold the rolling member in contact with the curved path. <IMAGE>

Title: Continuous flow vessel for waste water recovery
Inventor: ZEILINGER DIETER
IPC: B01D21/08
Filed: 1988-02-15
Abstract: To avoid vortexes which interfere with the slow ascension process of bound pollutants in water and decrease the efficiency and performance of these plants, the physical law of mutual cancellation of waves is applied. This is achieved by the water flowing in a star shape from the outer shell of the vessel to the centre where the outlets are arranged vertically one above the other.

Title: Valve block assembly
Inventor: SCHUETZEICHEL WINFRIED
IPC: B60T15/02
Filed: 1988-04-20
Abstract: A description is given of a valve block assembly for anti-lock systems for motor vehicles, the said assembly comprising solenoid valves (38).

Title: Centring element
Inventor: SCHANZ MANFRED
IPC: B23Q3/18
Filed: 1988-05-14
Abstract: A centring element serves to connect two parts which are to be aligned with respect to one another and have receiving bores which are aligned with respect to one another in the centring position and are intended for the centring element. The centring element (1) exhibits a double-cone part (2) which is penetrated by a clamping screw (6) and on which two separate cone sleeves (4, 5) are displaceably mounted. By virtue of the clamping screw (6), the cone sleeves can be oppositely adjusted in the axial direction towards one another, said sleeves widening radially at the same time. Consequently, two parts which are to be connected can be braced three-dimensionally. The essential point here is that, during fixing in the bores of the parts, said parts are, at the same time, also drawn together and thus rested against one another (Fig. 1). <IMAGE>

Title: Apparatus for the compaction of dust-like or pulverulent, granulated or pelletised bulk material in storage or transport containers
Inventor: WIDMANN ROLAND
IPC: B65G69/02
Filed: 1988-08-25
Abstract: A vibration unit (22) with a vibration generator (11) is mounted in the centre of the filling-material space (10) of a bulk-material container (1) in a manner supported largely freely and flexibly on all sides. Starting from the vibration unit, the bulk-material content is set in vibration until included gas can escape and the filling material additionally fills the small voids thus obtained. As a result, a higher and more uniform density of the bulk material is achieved, and larger quantities by weight can be introduced in a predetermined space. The volume and loading capacity can be better utilised. Moreover, vibrations can be largely kept away from the container, and the vibrational energy introduced can be supplied for degassing and therefore for an increase in density. Insofar as the vibration generator is supported on the container wall, there should be mounted between it and this container wall a vibration uncoupler which can consist completely or partially of rubber or rubber-like material, but which can also have pneumatic springs or metal springs.   <IMAGE>

Patent DE-3833214-A1 (DE)
Title: Fuel injection system
Inventor: SASS WOLFGANG DIPL ING
IPC: F02M69/00
Filed: 1988-09-30
Abstract: A fuel injection system for internal combustion engines is proposed, in which a defined proportion of a predetermined volume of fuel is abruptly vaporised and due to the pressure increase inside a fuel-enclosing chamber a defined quantity of fuel is sprayed by way of each valve respectively. An electronic control module calculates the duration, that is the energising time of a high frequency induction coil, triggered by a high frequency generator, which coil generates heat in an object which is arranged in a fuel-filled chamber. The generation of heat results in the formation of vapour and hence a pressure increase in the said chamber, as a result of which fuel in the liquid or vapour phase is displaced from the said chamber.

Title: Gear-change device
Inventor: PRUESS LUDWIG DIPL ING
IPC: F16H63/48
Filed: 1989-01-26
Abstract: The invention relates to a gear-change device for a vehicle with an internal combustion engine and a step-change gearbox, connected to the input of which is an automatic clutch, the actuating element of which is connected by means of signal transmission devices both to an accelerator-pedal switch element and to a selector lever device essentially formed by a selector lever, a selector-lever slot provided with the detent positions for different gear stages, and by connection means for signal transmission to the actuating elements of the tranmission element to be connected to one another non-positively. In this arrangement, assistance to the parking brake without additional structural modifications to the step-change gearbox is made possible by virtue of the fact that the selector-lever slot has an additional detent position in which are arranged switching elements which are connected in such a way, via connection means for signal transmission, to the actuating element of the clutch on the accelerator pedal switch that, after displacement of the selector lever into the additional detent position, the transmission elements of at least one gear stage are connected to one another non-positively, the starting clutch is actuated in the closing direction when the internal combustion engine is at rest and remains open after the internal combustion engine has been started, even when the accelerator pedal is actuated. <IMAGE>

Patent DE-3929821-A1 (DE)
Title: A process to sever rovings - utilises existing features on the roving frame to separate full bobbins of long staple rovings
Inventor: GRAU GERHARD DIPL ING
IPC: D01H9/16
Filed: 1989-09-07
Abstract: On a roving frame, a process to automatically separate ends of rovings between flyer and full bobbins, utilizes the tension on the roving between flyer leg guide and the top of the bobbin as it is drawn away over a distance which exceeds the staple length of the roving. The roving frame has existing features which enable long staple roving to be sepd., in order to produce a fringe at the flyer leg, and a length to hang down at the side of the bobbin. By stopping the drafting, the roving (12) is tensioned in the flyer lead, and an additional turn of the flyer, or of the bobbin, or both combined, will sever the roving at the finger (5). A further method is to lower the lift rail (9) while the draft, flyer and bobbin are all held stationary. On machines having a hinged (8) lift rail (9), the outward movement may be utilized to sever the roving at the finger (5). The control of the separate drives at each section is incorporated into the programme, according the method selected. USE - To separate rovings of longer staple length, without having to utilize additional devices.
