Patent DE-3122304-A1 (DE)
Title: >>Circuit arrangement for transmitting a digital signal with a reduced sampling frequency<<
Inventor: DEMMER WALTER ING GRAD
IPC: H04N19/00
Filed: 1981-06-05
Abstract: A digital television signal is present with a high sampling rate which corresponds to the luminance-signal resolution although its own bandwidth is, for example, eight times smaller. In order to be able to simplify the delay device, the digital colour signal is subjected to a sampling-rate reduction before the delay; the sampling rate is increased again thereafter. <IMAGE>

Title: Adjustable protective hood for angle grinders or similar electric tools
Inventor: KAISER BERND ING GRAD
IPC: B24B55/05
Filed: 1981-09-10
Abstract: An adjustable protective hood for angle grinders or similar electric tools which is guided and can be fixed on the clamping neck of the tool is to be easily adjusted into any desired position, without any additional tool, and, in terms of its prestressing and securing against rotation, is to have values which remain the same irrespective of the operator. For this purpose, the invention proposes to design the guide part of the protective hood as a closed ring which is adapted, in terms of its internal diameter, to the clamping neck of the tool and is held, prestressed, in position and secured against rotation by means of fastening elements, using disc-shaped securing bodies. <IMAGE>
Patent DE-3137301-A1 (DE)
Title: Method and device for handling small parts in manufacture
Inventor: GOTMAN ALEXANDER
IPC: B28D5/00
Filed: 1981-09-18
Abstract: For reliable (safe) handling during manufacture, the individual parts are bonded in a regular arrangement onto a stretched membrane consisting, for example, of rubber. During manufacture and processing of semiconductor chips, the semiconductor wafer which is intended to be split up to produce the chips or cubes can even be bonded onto the stretched membrane flat as an entity, can then be cut along the fracture lines using a machine and can finally be broken up to form the chips, in that the membrane with the wafer bonded onto it is bulged forwards from the rear so that the wafer breaks along the fracture lines. The chips which are thus produced are then located on the membrane as a regular arrangement of mutually separated individual elements. In order to calibrate the chips, each individual one of them is pressed by the membrane out of the plane of the other chips, using a plunger which is operated by compressed air, and the chips which are adjacent to the item being tested are at the same time held back by an induced suction draft which is applied from underneath the membrane. In this way, the chips are held in the correct position for testing, and subsequent insertion into an electrical circuit, which is moved into position from above, is also ensured. <IMAGE>
Patent DE-3143922-A1 (DE)
Title: Clog-free guiding device for bulk materials, in particular on loading booms of large open-pit mining apparatuses
Inventor: KERSTEN PETER DIPL ING
IPC: B65G47/18
Filed: 1981-11-05
Abstract: The aim of the invention is to eliminate the risk of clogging in guiding devices, in particular charging hoppers, which are enclosed on all sides, and thus to reduce the mass required in the apparatus design. The object thus consists in providing a guiding device of this type which has a self-discharging mechanism when a fixed degree of clogging has been reached. The object is achieved in that hopper-shaped segments of a charging hopper are mounted pivotably in bearings (2) at the upper periphery and are connected in the lower region so they are shut sealingly relative to one another by means of flexible connecting elements having an adjustable prestress or by means of gravity masses (8) suspended from chains (7). <IMAGE>
Patent DE-3145647-A1 (DE)
Title: Curtain wall
Inventor: STRAUB THEODOR
IPC: E04B2/92
Filed: 1981-11-17
Abstract: The invention relates to a curtain wall with ventilation provided in the spandrel and/or floor region of the carcass structure, in particular a thermally insulated wall. The wall consists essentially of vertically extending mullions which are arranged mutually parallel and at a distance from one another and are constructed in the form of a T-section. The infilling elements, which can be formed by windows or panels, are pressed, in the region between two floors, from the inside against the inward-facing side of the outer flanges and held in this position by means of covering shells. The covering shells are screwed to the webs of the mullions. In the spandrel region, the panels are mounted from outside by being threaded between the holder and the inside of the mullion flanges. Situated behind the panels are cavities accessible through openings, so that the panels are ventilated. The mullions are situated in the entire wall region in the cold space of the wall, and a connection from the cold outside to the warm inside is avoided. Since a conventional lattice structure comprising mullions and transoms is not provided, the wall is able to withstand considerable movements in the horizontal and vertical direction and the transmission of structure-borne noise is reduced.

Patent DE-3210442-A1 (DE)
Title: Pair of book ends
Inventor: MOSER WERNER ING GRAD
IPC: A47B65/00
Filed: 1982-03-22
Abstract: Book ends are known as individual elements which, either as a result of their own weight or by virtue of their angular form, perform a supporting function in connection with the outermost books of a row. Individual elements have to be placed against the row of books by hand each time in the event of changes. The dependence on weight is disadvantageous and creates functional unreliability. In the proposed embodiment of a pair of book ends, whose two supporting elements are connected by a flat spring, a constant pressure is exerted on the row of books, irrespective of the length thereof. The retaining function is independent of the weight of the supporting elements. None of the standing books is required to serve as an aid for the supporting function. Drawing 1, Figure 1, shows the arrangement described. The spring strip which is passed through below the books is either flat or curved upwards. When the supporting elements are moved, the spring strip unrolls or rolls up without moving relative to the substrate. The supporting element can be produced from wood, glass, ceramics, metal or the like. <IMAGE>

Title: DC converter
Inventor: RIEWE FRANZ-JUERGEN
IPC: H02M3/156
Filed: 1982-12-15
Abstract: A DC converter is specified which operates in accordance with the isolating transformer principle. Said converter has a coil (L), which is connected to a DC voltage source (+U0), and in series with which a switch (S) is connected, which is operated by an oscillator (OS). At least two charging circuits are connected to the coil (L), in each case charging capacitors (C1, C2) being charged by them, via diodes (D1, D2) and switches (S1, S2), when the switch (S) is operated. The charging capacitors (C1, C2) are charged to voltages (U1, U2) of different magnitudes. The charging capacitors (C1, C2) are discharged via load resistors (RL1, RL2) so that the voltages (U1, U2) fall in a corresponding manner. Each voltage (U1, U2) is monitored by an associated comparator (K1, K2), the comparators supplying an L-output signal when the voltages (U1, U2) fall below predetermined values. The L-output signals of the comparators (K1, K2) switch the oscillator (OS) on and result in the associated switches (S1, S2) closing. As soon as one of the two monitored voltages (U1, U2) has reached its predetermined value again, the corresponding associated switch (S1, S2) is separated via the associated comparator (K1, K2) (Figure 1). <IMAGE>
