Title: Laser beam range finder test unit - employs echo signal from sensors through interference filter, diode matrix, amplifier, schmitt trigger, memory interface and display
Inventor: SCHOLL FRIEDHELM ING GRAD
IPC: F41G3/32
Filed: 1980-08-16
Abstract: The functional testing unit relates to a laser beam distance measuring device for a weapon. It includes a small target table (1) and a large target table (2). The small table is crossed by two orthogonal lines (3,4) representing the vertical and horizontal axes of the cruciform sight unit, respectively. Along each of these axes is an array of equally spaced sensors (6,5), typically photodiodes. In use, a laser beam striking the target impinges on and energises some of the diodes, which senses a Doppler echo type return signal to an interference filler, to eliminate stray radiations, a diode matrix, amplifier, Schmitt trigger, memory and interface. The latter works in conjunction with a transmitter, receiver and a display unit.

Title: Multi:segment imaging appts. is fluorescent active display - with liq. crystal polymer layer between each electrode pair
Inventor: KRUEGER HANS DIPL PHYS
IPC: G02F1/13357
Filed: 1980-08-18
Abstract: Equipment for the prodn. of multisegment images has a fluorescent body (plate), consisting of a transparent support with a refractive index of over 1 and contains fluorescent particles. On the electrode side, in each image segment region, there are 2 transparent electrodes with a liq. crystal (LC) layer between them which can be switched between 2 optically different states. The 2 electrodes of each segment are in a plane between the body and the LC layer and form an interdigital structure. The LC layer consists of a solid polymer with switchable mesogenic constituents. The electrodes can be placed directly on the body and/or polymer layer. The mesogenic constituents of the polymer layer are aligned uniformly in the field-free state, perpendicular to the plane if they have positive dielectric anisotropy and parallel to this for negative dielectric anisotropy, and take on a periodically disturbed texture on applying the switching voltage. The polymer layer can contain a pleochroitic dyestuff. The non-electrode side of the body has a scattering surface, pref. a pigment surface, in each image segment zone and this and/or the polymer layer can be coloured. The polymer layer can have another electrode on the side away from the body. The equipment is a fluorescent active display (FLAD). It can be produced easily and can have a large collector area.

Patent DE-3102059-A1 (DE)
Title: Geared pump
Inventor: DWORAK WILHELM
IPC: F04C14/26
Filed: 1981-01-23
Abstract: The geared pump shown in Figure 1 has a flow regulating valve which essentially comprises a diaphragm (16) and a seating valve (25) connected in parallel. The force of a spring (27) and the pressure behind the diaphragm act on the seating valve via a plurality of balls arranged in a bore (21), whilst on the other hand the delivery pressure in front of the diaphragm acts on the valve body. When a certain pressure differential is reached the valve body is lifted from its valve seat and excess pressure medium flows back to the intake side of the pump by way of a connecting duct (31 to 33). The arrangement of a seating valve body and a plurality of balls has the advantage compared to the conventional arrangement of a valve slide that if the cover (12) is bent under pressure this does not result in jamming of the valve parts. The flow regulating function is thereby always assured. <IMAGE>

Patent DE-3113543-A1 (DE)
Title: Extensible table
Inventor: ODERMATT KARL
IPC: A47B1/08
Filed: 1981-04-03
Abstract: In extensible tables having a multi-part table-top and having at least one auxiliary stand (HST) in the central region of the table- top, there is the problem of simple and light handling during extension and retraction of the table-top parts (PT1-PT5) in terms of the support of the auxiliary stand on the floor during displacement. The solution provides a rolling support member (WT) at the foot (FU) of the auxiliary stand with an axis of rotation arranged transversely to the direction of extension (X) so that the auxiliary stand can be supported permanently on the floor during the extension and retraction movement without impairing the smooth operation. A retention of the auxiliary stand during extension or a release of retention means for retraction is not required. The rolling support element expediently designed as a comparatively large roller can be mounted concealed between side parts (TS) of the auxiliary stand and does not then impair the appearance. <IMAGE>

Title: Method and circuit arrangement for setting up conference connections in telecommunications systems
Inventor: ROBRA JOERG DR ING
IPC: H04Q3/00
Filed: 1981-11-07
Abstract: In telecommunications switching systems, the performance of conference calls among a plurality of subscribers is enabled with conferencing equipment. The circuit cost of known conferencing equipment is relatively high and balancing for different subscriber loop line lengths is not easy to implement. For adaptation of branches in a telecommunications system, the impedance of the subscriber loop which is to be connected is measured and a compensation circuit is inserted before connection of an additional subscriber terminal to an existing exchange connection between two subscribers. The compensation circuit and additional subscriber terminal are connected simultaneously to the existing exchange connection. A bridge balance with an adjustable impedance can be implemented for impedance measurement and compensation, and the impedance thus obtained can be supplied to a negative impedance converter.

Title: Reading aid for loose-leaf collections
Inventor: WOLSKI GEB EY
IPC: A47B23/04
Filed: 1982-01-29
Abstract: The invention relates to a mechanically functioning book-rest for loose-leaf collections. The purpose of the invention is the possibility of being able to read a loose-leaf collection in any opened position, whether at the front, in the centre or at the back, at an angle as if the loose-leaf collection had been opened exactly in the middle. The object of the invention is to avoid the continuously necessary head movement and the poor body posture when reading from the loose-leaf collection. This object is achieved in that the retaining plate (2) for the spine of the book itself performs a counterbalancing action about its longitudinal axis by means of a torsion rod (4) when a shift in weight takes place as a result of the turning of pages in the loose-leaf collection. The spine of the loose-leaf collection is retained by retaining brackets on the retention plate (2) for the spine of the book, so that the loose-leaf collection does not slip when leafed through. Two extension arms (6/7 and 8/9) give the reading aid a firm stance. In addition, the angle of inclination for reading can be varied. The reading aid is collapsible, the connecting piece (5) with the supporting bracket (3) being pushed downwards along the torsion rod. <IMAGE>

Patent DE-3205827-A1 (DE)
Title: Suction injection devices with vacuum store
Inventor: WAGNER WOLFGANG DR MED
IPC: A61M5/42
Filed: 1982-02-15
Abstract: The invention relates to medical technology, more specifically to the field of injection techniques. A cannula shaft is located as the continuation of a conical bore hole for attachment of an injection syringe in a closure plate in the centre of an inner cavity which is widened at the bottom to form a suction cup. Above the suction cup and the inner cavity there is located another larger, outer, jacket space in which a vacuum is available in an industrially prefabricated manner and which is closed by an annular membrane at the top and relative to the closure plate. A pipe is arranged around the cannula shaft so as to be displaceable in the inner cavity, and the lateral opening of this pipe is flush with a valve opening to the outer jacket space on upward displacement. Pressing the device against the skin results in the particular displacement of the pipe, which, after contact of the skin with the edge of the suction cup, opens the vacuum space toward the skin, resulting in lifting of the skin into the tip of the cannula shaft. If the bore-hole of the closure plate is then opened - by removal of a membrane - an injection syringe can be applied and emptied underneath the skin. <IMAGE>
