Title: Lifting platform with processor control
Inventor: KREMER ERWIN ING GRAD
IPC: B66F17/00
Filed: 1988-03-10
Abstract: The subject matter of the application is a lifting platform with a boom which can be erected and on which a hydraulic cylinder connected to a hydraulic pump acts. The lifting platform has a safety device for limiting the load moment diverted to the platform frame. The safety device feeds a signal dependent upon the load moment to a processor. Furthermore, an erecting-angle transmitter is connected to the processor so that the erecting angle permissible in each case is detected as a function of the measuring signals from the safety device and the control of the platform can be blocked if the erecting angle falls below the permissible value. In such a lifting-platform control, the sensors for the measured variables fed to the computer are at the same time to permit functional monitoring of the control system. To this end, the processor constantly checks whether the zero value of the load moment is reached upon stoppage of the boom at least in the resting basic position, that is, after the end of the lifting/lowering movements, and whether the erecting angle increases and the load moment decreases during the lifting operation of the boom and whether the erecting angle decreases and the load moment increases during the lowering operation of the boom. Furthermore, the processor checks the conditions that there is an increase in the erecting angle during the lifting of the boom and that there is a decrease in the erecting angle during the lowering of the boom. If the preset conditions are not complied with, the processor causes the control of the boom ... Original abstract incomplete.

Title: Device for connecting two waveguide pieces
Inventor: BUECHELER GERHARD R
IPC: H01P1/04
Filed: 1988-04-29
Abstract: Union nuts are known for connecting waveguides, which union nuts have a thread on one side and a web on the other side, by means of which web they are held on a circlip which is fitted around the waveguide piece. A device which can be handled easily and has low weight is specified for the connection. The device according to the invention consists of a nut (2) having two internal threads (21, 22) which run in the same direction but are of different diameters. The pitch of the first internal thread (21) having the smaller diameter is less than that of the second internal thread (22) having the larger diameter. The nut (2) is initially screwed onto a first waveguide piece (1) by means of the first internal thread (21) and is then screwed by means of the second internal thread (22) onto the second waveguide (3) or onto a threaded piece which is screwed onto the second waveguide piece. The different pitch of the threads results in the waveguides (1, 3) being moved towards one another and touching on the flange faces (13, 33). Waveguides having very small dimensions. <IMAGE>

Patent DE-3838820-A1 (DE)
Title: Balancing the measuring and comparison light beam in light-electrical photometers
Inventor: LORENZ GERHARD
IPC: G01N21/53
Filed: 1988-11-17
Abstract: The invention relates to a method for balancing the intensity of the measuring and comparison light beam in light-electrical photometers. Such two-beam photometers use a comparison beam path whose intensity is a function only of the intensity of the light source, in addition to the actual measuring beam path whose intensity represents the direct measured variable. By now determining the intensity of the measuring beam in relation to that of the comparison beam, the measured value displayed by the photometer is automatically corrected of errors which can occur as a result of any intensity changes of the light source. The correction is carried out, according to the prior art, by means of optical-mechanical devices in the beam paths, with whose help the intensity of one of the two beams can be balanced to that of the other by attenuation. The adjustment of the device necessary for matching the intensity is the indirect measure of the photometric measured value. Such attenuation devices are costly and a possible source of errors as a result of maladjustment or soiling. The method which underlies the invention makes unnecessary the devices for light attenuation in the beam paths of the photometers by means of the use of a light source of variable brightness and of electronic measured value stores.
Patent DE-3840335-A1 (DE)
Title: Hydraulic brake pressure proportioning device for motor vehicle hydraulic brake systems
Inventor: SCHULZE BERND-GUIDO DIPL ING
IPC: B60T13/12
Filed: 1988-11-30
Abstract: In brake systems with known pressure-reducing brake pressure proportioning devices there is a risk of the rear wheels being overbraked in the event of defects on the brake pressure proportioning device. The new brake pressure proportioning device overcomes the said risk. In addition to the usual inlet hydraulic chamber and the second hydraulic chamber, it has a third hydraulic chamber, separated from the second hydraulic chamber by a pressure-boosting piston, which third chamber can be connected to the rear wheel brake cylinders. The hydraulic pressure of the third hydraulic chamber is boosted in relation to the hydraulic pressure of the two other hydraulic chambers. In addition a bypass line leading from the third to the first hydraulic chamber is provided, which is opened by a check valve device arranged therein when the reducing control function of the brake pressure proportioning device has been lost. The brake pressure proportioning device is suitable for use in a motor vehicle brake system in which the piston surfaces of the rear wheel brake cylinders are dimensioned so much smaller than those of the front wheel brake cylinders that a brake power distribution of the vehicle is produced in which any overbraking of the rear wheels is excluded in the event of equal pressure on the front wheel and rear wheel brake cylinders. <IMAGE>

Title: Electronic lap counter
Inventor: HESSE KURT
IPC: A63H18/00
Filed: 1989-01-31
Abstract: The invention relates to an electronic lap counter for a toy racetrack having at least one vehicle. The lap counter comprises a sensing device for producing a lap-specific signal when the vehicle passes the sensing device. The sensing device is connected to an evaluation unit by means of which data (e.g. instantaneous lap time, fastest lap time, final time) which are determined with reference to the sensed signals and which characterise the operation of the racetrack can be determined. The evaluation unit used is a personal computer (PC), the program for operating the PC as an evaluation unit for lap counting being loaded into the PC by means of a diskette. The data determined by the PC on the basis of the sensed values are displayed via a customary cathode ray screen with reference to the respective driver or vehicle. The sensing device comprises a currentless racetrack area on which the vehicle travels in a currentless fashion, the pulse or pulses produced in this way being tapped off at the racetrack. The pulse or pulses sensed are subjected to pulse shaping by means of a pulse shaper (12) and ordered chronologically by means of a parallel-serial convertor (13) before they are fed to the PC. <IMAGE>

Title: Method and arrangement for setting up the web tension prior to start-up
Inventor: HANK DIETRICH DR ING
IPC: B65H23/10
Filed: 1989-02-27
Abstract: The invention relates to a method and an arrangement for setting up the web tension prior to start-up in a web-fed printing machine. The invention is based on the object of already tensioning a web of printing carrier, drawn by hand or by means of a drawing-in device into the web-fed printing machine, prior to start-up to the extent that the web tension is within the range required for printing. The object is essentially achieved according to the invention in that, with the drawing-in device blocked and disconnected, a stepping drive is switched on for shaking with an alternating direction of rotation - the directions of rotation fulfilling a forward/backward ratio of greater than 1:1 - and remains switched on until a tensiometer roller arranged in the path of the web signals a predetermined web tension value. <IMAGE>
Patent DE-3907570-A1 (DE)
Inventor: SCHRAMM WALTER
IPC: C07C7/144
Filed: 1989-03-09
Abstract: In the production of olefines by the thermal splitting of saturated hydrocarbons a hydrogen-containing hydrocarbon mixture is obtained which is broken down into individual fractions in several cleaning stages. At least part of the hydrogen is separated from the ethylene-containing fraction at a suitable stage in its cooling by means of a diaphragm. This produces a drop in the hydrogen partial pressure in the cooling inflow of ethylene to be separated which makes it possible to raise the temperatures in the subsequent condensation stages.

Title: Method and device for radio transmission in underground mines without waveguides
Inventor: RAETZ WALTER DIPL ING
IPC: H04B7/26
Filed: 1989-03-10
Abstract: Radio transmission over a long distance without waveguides is possible in underground mines in the vicinity of the primarily longitudinally extended mine building, by means of an arrangement of a plurality of radio fields which complement one another. These fields are set up with the aid of locally installed transceiver installations and directional antennas assigned to the radio fields and are used for communication between mobile radio stations via the local transceiver installations. The directional antennas are set up for transmission with an optimum polarisation plane in the underground mine in such a way that either a horizontal or a circular wave front is radiated. Once it has reached its maximum extension, a radio field set up in this way is supplemented by a further radio field as often as required by the longitudinally extended space for a radio link. At branches, sharp bends and remote individual cavities, further radio fields are in each case set up so that a complete radio link is provided in these areas also (Fig.). <IMAGE>
