Patent DE-3737350-A1 (DE)
Inventor: SCHLINKHEIDER WILFRIED
IPC: F04B9/12
Filed: 1987-11-04
Abstract: A pump arrangement (1) has two alternately conveying separate pumps (2, 3) and one axial piston motor (14). The piston rod (19) of the latter is divided into two sections (20, 21) each assigned to a separate pump (2, 3). Their spacing is variable by means of an adjusting device (22). Each section (20, 21) is connected to an actuating element (39, 40), each of which is assigned to one of the two limit position switch elements (37, 38) and actuates this at the end of each motor stroke. The axial piston motor (14) has two pistons (6, 11), each connected to a piston rod section (20, 21), which pistons are located in the area of an end surface (41, 42) of the piston displacement (15, 16) when the associated limit position switch element (37, 38) is actuated. If a minimum of two double pumps are used, a pump arrangement is created for two-component or multiple- component operation in which the component pumps are steplessly lift- adjustable, do not have to perform any dead travel and thereby work with low pulsation. <IMAGE>

Title: Method and device for testing the response pressure of a safety valve on site
Inventor: BENE FERENC DR
IPC: F16K37/00
Filed: 1988-03-18
Abstract: For the testing of the response pressure of a safety valve on site, a force acting in its opening direction is continuously increased up to the response of the safety valve, which is acoustically perceptible by means of medium flowing out, so that a pressure can be determined at this instant with reference to the valve sealing area and directly indicated as response pressure, taking into account the pressure measured separately upstream of the safety valve. The device used for this purpose has a connection disc on the valve side and a support disc, which are connected to a frame by means of connecting rods, a coupling apparatus which can be brought into engagement with the safety valve and is connected to a lifting apparatus held on the frame side and acting in the opening direction of the safety valve, to which lifing apparatus a force measuring cell is assigned, and an apparatus to measure the pressure upstream of the valve. The lifting apparatus has an intermediate piece (4) on the support disc (2) with a thrust bearing (7) for a hand-actuable screw spindle (6) which is in threaded engagement with a lifting sleeve (6) guided axially displaceably in the intermediate piece (4), the lifting sleeve being connected, for its part, to a mounting (11, 12, 13) for the force measuring cell (14) carrying the coupling apparatus (16, 17, 18). An indicating apparatus (21) is coupled to the force measuring cell (14) and the apparatus (20) to measure the pressure upstream of the safety valve. <IMAGE>

Patent DE-3821438-A1 (DE)
Title: Polarisation diversity receiver
Inventor: NEIDLINGER STEPHAN DIPL ING
IPC: H04B10/61
Filed: 1988-06-24
Abstract: Optical heterodyne receivers generally require very expensive polarisation control for the received light or the light of the local laser. In polarisation diversity receivers, no optical polarisation control is required if the heterodyne wave is split into two polarisation directions which are orthogonal in relation to one another, the two generated signals are demodulated separately and the baseband signals are then added. In a known solution, following an input-side 2.2 coupler, a division is carried out by means of two polarisation beam splitters to form four light beams which are in each case fed separately to a photodiode. To reduce cost, a polarisation beam splitter whose two output terminals are in each case connected to input terminals of 2.2 couplers is inserted according to the invention into the connection between the input terminal for the received light and an input terminal of a 2.2 coupler. The output terminals of the second 2.2 coupler and one output terminal of the first 2.2 coupler are connected to assigned photodiodes, and diversity currents which are to be demodulated separately are obtained through difference formation of the generated photocurrents. <IMAGE>

Title: Indirectly luminous display surface
Inventor: MOELLER HANS JOACHIM DIPL ING
IPC: F21V8/00
Filed: 1988-10-24
Abstract: A display surface is to be made in such a manner that it is clearly visible in the case of various possible applications without additionally illuminating a room which, for operational reasons, has to be blacked out (dimmed, darkened). Light-emitting diodes are fitted to the edges of a display surface, which consists of a transparent plastic with embedded fluorescent material, in such a manner that they can uniformly inject their light into the sections of the display surfaces. The wavelength of this light is matched to the wavelength of the fluorescent dyes embedded in the plastic. For contrast formation, partial surfaces are coated with a reflecting layer and/or provided with a contrasting print. In the case of the display surface according to the invention the entire arrangement is designed in such a manner that a clearly visible display is produced, it being possible to achieve good contrasting effects. The display surface is suited to use in darkened rooms since it emits an extremely small amount of light to the environment.

Title: Safety ski binding for monoskis or snowboards
Inventor: EMERT ANTON
IPC: A63C10/08
Filed: 1988-11-11
Abstract: A safety ski binding for the voluntarily, and in the event of over-stressing involuntarily, releasable support of a pair of boots on a monoski or snowboard holds the boots, in the state of use, either parallel to each other in the direction of travel (for monoskis) or obliquely or transversely to the direction of travel (for snowboards). In order to guarantee the release of both boots when one foot is overstressed and to provide a binding of simple design which is not fault-prone, corresponding binding parts for both shoes, which can be moved against the lateral release resistance of at least one spring and/or influence force transducers provided for lateral forces and assigned to electronic circuits, are coupled to each other in such a manner that these binding parts release simultaneously and in the same direction. In this arrangement, the total release resistance of correspondingly mechanically coupled binding parts in this plane of loading is so dimensioned, towards each side, that it at least approximately corresponds to the value given for a leg in DIN 7881.
