Title: Device for receiving a coordinate measuring machine on a foundation (base)
Inventor: DONAT HORST DIPL ING DR ING
IPC: G01B21/00
Filed: 1987-04-04
Abstract: The invention relates to a device for receiving a coordinate measuring machine on a foundation with the aim of permitting optimum use of optoelectronic scanning methods. The object is, above all, to prevent the effect on the frame of the measuring machine of bending (flexural) and torsional moments caused by migrating loads. Receiving elements (sleeves) permanently arranged in the frame and on which a baseplate is mounted surround a gas volume which is sealed at the bottom by an annular diaphragm in the central opening of which there is arranged in a gastight fashion a supporting member which rests on the foundation directly or by means of intermediate elements. Connected in parallel with the gas volume is a directional valve which adjusts the pressure as a function of the level of the gas volume and which keeps the level of the gas volume constant even in the event of a changing load on the baseplate. <IMAGE>

Title: Hydraulic dual-circuit brake system for a road vehicle
Inventor: BURCKHARDT MANFRED DR ING
IPC: B60T8/28
Filed: 1987-08-26
Abstract: In a hydraulic dual-circuit brake system for a road vehicle with front axle/rear axle brake circuit division, a solenoid valve is provided, by means of which the main brake line of the rear axle brake circuit can be shut off from the brake assembly when a vehicle deceleration threshold value ZS is exceeded in braking. This shut-off is maintained until the vehicle deceleration is again less than a value Zs, which is lower than the response threshold ZS. The wheel speed sensors of an antilock system provided on the vehicle are used to detect the vehicle deceleration. The brake system permits the utilisation of high braking decelerations with nevertheless favourable brake power distribution in the partial braking range, without loss to the dynamic stability of the vehicle.

Title: Fuel injection device
Inventor: SCHWEIMER GEORG WOLFGANG DR
IPC: F02M57/02
Filed: 1987-09-11
Abstract: A fuel injection device, especially for diesel internal combustion engines with direct fuel injection, is described, which has a pump-nozzle element (1) with a step piston (6), loaded by a return spring (11) and displaceably held in a working cylinder (8, 10) of stepped diameter of the pump part. It is proposed that the step piston have a servo piston (7) of larger diameter and a pump piston (9) of smaller diameter. The fuel injection device also has a metering pump (2), which is connected by way of a pressure relief valve (3), acting on two sides, to a servo pressure chamber (18) of the pump-nozzle element (1) assigned to the active surface (7a) of the servo piston (7). In order to ensure a soft, damped end to the return stroke of the step piston, it is proposed that the preloading of the return spring (11) and the static pressure loading the active surface (7a) of the servo piston (7) and adjusted by the pressure relief valve (3, 31) in the servo pressure chamber (18) be matched to one another in such a way that, after each working stroke of the metering pump (2), the step piston (6) returns into a position which lies below a stop (27). <IMAGE>

Title: Universal cutter-head setting and vibration-measuring system
Inventor: SELBACH GERD PROF
IPC: B23Q17/22
Filed: 1987-10-01
Abstract: By the use of controllable laser beams in a fixed geometric arrangement, the universal cutter-head setting and vibration-measuring system fulfils the requirements occurring with the dynamic setting of cutter heads. A modular measuring system for logging deterministic as well as stochastic measured values solves the problem of optimisation existing here. The size adaptation is effected by the exchange of the housing and optical subassemblies in a portable measuring system. The measurements can be carried out both on the machine tool and in the laboratory, in the course of which attention need not be paid to temperature fluctuations, since the system produces no absolute values but makes a comparison for any preset measured value. Time-dependent disturbance variables with an effect on the level of the measured values can be logged and can be evaluated according to the trend via the probability of the standard deviation and eliminated. The system permits the interlinking of data typical of the tool with the quality of the workpiece surface produced.

Title: Vibrating grid
Inventor: GRESCHNER JOACHIM DR ING
IPC: B07B1/50
Filed: 1987-11-10
Abstract: The invention relates to a vibrating grid for fractionating composite soil or debris mixtures and has the purpose of increasing the effectiveness of the fractionating process in the case of non-cohesive soils and of creating the possibility of screening composite soils interspersed with cohesive soils with simple means. This is achieved in that, by means of an additional elastic mounting, grid bars adjacent to a bridge which bears the vibrator and is connected to every second grid bar vibrate differently both in terms of their amplitude and in terms of their mode of vibration and phase position and in that the centre of mass of the frame is, furthermore, located between the plane of the grid bars and the plane, situated parallel to the latter, of the supports of the bridge on the frame (Figure 2). <IMAGE>

Title: Main control slide for a hydraulic actuator (jack) of an aircraft control surface
Inventor: BEYER FRIEDER DIPL ING
IPC: B64C13/42
Filed: 1988-01-11
Abstract: A hydraulic actuator of an aircraft control surface is controlled by a main control slide, the actuator and the main control slide each being designed to be duplicated, for the purpose of redundancy. The main control slide (20) is operated by a linear motor (22). If an obstruction to the movement of the control slide is detected, the piston (23) of the control slide (20) must be acted on with greater force in order to overcome the sticking force. Instead of applying a multiple of the rated power to the linear motor, as was normal in the past, an electrohydraulic auxiliary control slide (30) is arranged on the housing of the main control slide and moves the piston of the main control slide into the required position hydraulically. <IMAGE>

Title: Vane-cell pump
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: B60T17/02
Filed: 1988-02-20
Abstract: The vane-cell vacuum pump is used to generate a vacuum for, in particular, the braking system of a motor vehicle. The pump is driven by one of the motor shafts and for this purpose is flange-mounted on the motor housing in alignment with the motor shaft. To compensate for alignment errors, this is effected with a loosely inserted coupling disc. In order to be able to stock and assemble the pump together with the coupling disc, the pump housing (4) has a bearing hub (37) which projects into the motor housing (2). At the end of the inner circumference of the bearing hub (37) there is inserted a securing ring (8), the internal diameter of which is smaller than the external diameter of the coupling disc (15). The coupling disc is connected to the motor shaft and the rotor shaft in each case by means of axial projections (16) and recesses (15). <IMAGE>

Title: Two-roller machine for pressure treatment of granular material and method for operating such a machine
Inventor: RAMESOHL HUBERT
IPC: B30B15/30
Filed: 1988-02-29
Abstract: In the operation of roller presses for compaction of or for pressure treatment of granular material, for example for the purpose of so-called material bed comminution of brittle material to be ground, such as cement clinker, not only fresh coarse material but also a large quantity of fine material, for example in the form of recirculated grit from a downstream separator, is fed into the material feed chute arranged above the roller gap. In this arrangement, deaeration problems can occur, in particular in the case of high feed material beds, that is to say the air pressed out of the feed material as a result of the high-pressure pressing cannot escape. For the purpose of solving the deaeration problem or degassing problem, it is proposed according to the invention that the material feed chute is subdivided, by a partition (12) extending along the roller gap and downwards as far as the vicinity of the latter, into a chute (a) for the feed of coarse material and into at least one chute (b), situated on the other side of the partition, for the feed of fine material, according to a special feature of the invention the level of the coarse material in the chute (a) being kept lower than the level of the fine material in the chute (b). <IMAGE>

Patent DE-3813546-A1 (DE)
Title: Oscilloscope
Inventor: SCHULZE WOLFGANG
IPC: G01R15/00
Filed: 1988-04-22
Abstract: Differential amplifiers can be used as multiplexers by means of an inhibiting transistor inserted into the emitter circuit. It is the object of the invention to use a basic circuit of this type for various switch functions which can be integrated on an analogue array. According to the invention, in each case at least two of these differential amplifier stages form one differential amplifier group (c, d; g; h) having the same function. At least two of the differential amplifier groups (c, g, h) thus formed exhibit a different function. Thus, a first differential amplifier group (h) provides for switching over differential amplifier stages having different gain and a second differential amplifier group (g) provides for switching over of channels (A, B, C). The invention can be used in instrumentation, particularly in multimeters and oscilloscopes. <IMAGE>

Title: Process for bonding adhesive-repellent plastic surfaces by means of an adhesive
Inventor: STIEFEL GOTTFRIED ALFRED
IPC: C08J5/12
Filed: 1988-09-28
Abstract: It has hitherto not been possible to bond adhesive-repellent plastic surfaces, for example films made from such plastics, directly to one another. The novel process is intended to enable even adhesive-repellent plastic surfaces to be bonded to one another. The novel process is divided in one of a number of variants into the following process steps:   (a) the surfaces to be bonded to one another in pairs are slightly melted by the action of heat, (b) an adhesive is applied to at least one of the surfaces prepared in this way, and   (c) the two plastic surfaces are pressed onto one another.   In this way, adhesive-repellent plastics can be bonded to one another without problems and without special chemical pretreatment.

Title: Method and arrangement for controlling a control lamp
Inventor: SJOEQVIST DOUGLAS
IPC: G08B5/36
Filed: 1988-11-09
Abstract: A control lamp is arranged to indicate two different operational states in the case of a member. The one operational state is indicated in that the lamp does not luminesce. The other operational state is indicated in that the lamp is controlled so as to alternately luminesce in a continuous or flashing manner. The time periods in which the control lamp is controlled so as to luminesce continuously are longer than the time periods in which the control lamp is controlled so as to luminesce in a flashing manner. In this way, the control lamp has an improved perceptibility compared to a control lamp which only luminesces continuously.

Title: High-pressure piston pump having a high intake capacity
Inventor: HAMMELMANN PAUL
IPC: F04B53/12
Filed: 1989-01-16
Abstract: A high-pressure piston pump is to be designed in such a way that it has a high intake capacity and that both during the intake stroke and during the discharge stroke delivery fluid is fed through the intake line to the intake chamber of the single- or multi-piston pump. In the high-pressure piston pump, the intake valve (12) is arranged in the piston (2). The piston has a piston rod (23) which extends through the intake chamber (24) of the pump and is linked at its free end to drive means. The cylinder (3) orifice (25) facing the drive means debouches into the intake chamber (24). A section of the piston is inserted into the intake chamber (24) during the intake stroke. This involves a portion of fluid being delivered from the intake chamber into the working chamber (5) whereas the remaining portion is drawn in on the feed side through an intake line (29), so that during the discharge stroke of the piston the full displaced amount determined by the working chamber (5) is delivered. During the discharge stroke, the piston is completely inserted into the cylinder (3), so that, in order to fill the volume which has become available in the intake chamber, delivery fluid is drawn in through the delivery line (29). The pump is used as a high-pressure flushing pump in cleaning appliances. <IMAGE>
