Title: Timing gear for a cam-operated lifting valve with devices for adjusting the valve timings
Inventor: VOIGT DIETER DIPL ING
IPC: F01L9/14
Filed: 1985-10-23
Abstract: In order to prevent problems, which can occur in transmitting the valve opening force, generated by the cam (4) to the valve stem (7) by way of the pressure medium present in a hydraulic chamber (9), the pressure of the pressure medium in the hydraulic chamber (9) serves only to control the axial length of the device (8) for adjustment of the valve timings, whilst the valve opening forces exerted by the cam (4) are produced mechanically by way of a screw sleeve (11) running over a coarse pitch thread (19) on a central cylindrical projection (18) of the tappet (2). Normally this screw sleeve (11) is arrested by a friction sleeve (10), rotationally fixed by means of a longitudinal toothing (12) but axially displaceable with the latter, which friction sleeve is connected by frictional contact to the tappet (2). When the pressure in the hydraulic chamber (9) increases, this frictional contact is neutralised, so that the screw sleeve (11) can move along the coarse pitch thread (19) under the action of the valve forces so as to shorten the device (8), thereby advancing the valve closing point. <IMAGE>

Title: Digital measurement method for displaying measurements on a display
Inventor: ROPPELT GUENTER
IPC: G01R19/25
Filed: 1986-04-08
Abstract: During the sampling of a measurement signal for analog to digital conversion, measurement errors can occur if the measurement frequency is equal to the sampling frequency. This so-called aliasing effect is overcome according to the invention in that the blocking time intervals, during which no sampling takes place, are varied and a modulated sampling frequency is produced. The blocking time intervals are varied in this case such that synchronism between the sampling frequency and the measurement signal frequency is avoided. <IMAGE>

Title: Winding apparatus for winding up thin webs of material, in particular films
Inventor: SCHMIDT ANNEMARIE
IPC: B65H18/20
Filed: 1986-11-03
Abstract: In a winding apparatus for winding up thin webs of material, in particular films, on a winding core with circumferential drive of the winding core, it is provided that the winding core rests without end mountings loosely - that is to say exclusively with linear contact regions - on two rollers which are arranged in the axial direction of the winding core, are mounted at the ends and form a winding station. One of the rollers of the winding core is in each case fixedly arranged. The other is arranged displaceably on the winding core, transversely with respect to the axial direction and so as to correspond to the increasing diameter of the material being wound during the winding operation. One of the rollers is arranged such that it can be driven. As a result, the winding core is mounted in a freely supported manner. During winding, no tilting problems occur, the winding takes place turn by turn with uniform firmness, the achievable diameter of the roll is not restricted by structural elements of the apparatus, and the higher winding rate is better adapted to the current performances of production machines. <IMAGE>

Title: Method for developing and copying photographic films
Inventor: HUEBEL EGON DIPL ING
IPC: G03D15/00
Filed: 1986-12-22
Abstract: Exposed photographic films (1) are developed in photo labs. Copies (18) are subsequently produced. In the event of later repeat orders, the customer faces the problem of identifying negatives. The tasks thereby arising are: simplifying the process for repeat orders of photographic images for the customer, and providing the preconditions for automation measures. The object is achieved according to the invention by means of a method in which an individual distinguishing mark (identifier, tag) (15) is applied in the photo lab to each individual negative image (6) of the film (4), and in which a distinguishing mark (16), which corresponds to this distinguishing mark (15), is applied to the corresponding copy (18). The distinguishing marks (15, 16), which can be read by a person and/or machine, permit unambiguous assignments by the customer and during filling of the repeat orders for copies in the photo lab, as well as automation measures. <IMAGE>

Title: Subscriber equipment for wireless digital telephony
Inventor: CRITCHLOW DAVID N
IPC: H04M1/72502
Filed: 1986-12-22
Abstract: A base-band processor provides control of conversion of PCM signals at one bit rate to other bit rates. It converts received digital signals to voice signals and vice versa. It also provides echo cancellation where it uses dynamic memory to store received signals. PROM's store the echo cancellation program information as well as that for utilisation of the processor as a control processor.As a control processor it signals to the frequency synthesiser the frequency of operation for communication to the base station. The processor is directly coupled to a modem processor which is able to access the base band processor memory. This processor sends its signal at a predetermined sampling rate which are converted to analogue signals. The analogue signals are subjected to a cancellation process to reduce distortion. These signals are converted to an IF for addition to  the synthesiser frequency to result in an HF signal for transmission

Title: Suspension device, in particular for curtains
Inventor: MERZ ROGER
IPC: A47H15/04
Filed: 1987-02-03
Abstract: To be able to insert a glider (2), not only at the end or at a notch of a rail (1), into the rail (1) and nevertheless ensure secure holding of the glider (2) in the rail (1), the glider (2) has very specific dimensions, along with a special shape. The T-shaped glider (2) measures, from each end (2011, 2021) of its horizontal flanges (201, 202) up to in each case a remote bearing surface (2042, 2041), situated thereunder, of a projection (204), more than the width (B) of the rail opening (101). The projection (204) is provided between the horizontal flanges (201, 202) and a sewn-on eye (203) which forms the vertical T-flange. The projection (204) is partly separated from the sewn-on eye (203) by a longitudinal groove (205), the groove base (2051) being at most the same distance away from the remote flange end (2021) as the width (B) of the rail opening (101). It is thus possible, with a multi-step movement causing opposite pivoting movements and different sliding movements, some individual and some combined, for the glider (2) to be inserted into the rail (1). In another operation, causing other movements in a manifold sequence and combination, the glider (2) can be removed again. Unintentional removal, however, is not possible. A drawing-in aid can make possible the joint introduction of a large number of gliders. <IMAGE>

Title: Adjustable levelling board
Inventor: ZIEGLER KARL-HEINZ
IPC: E01C19/18
Filed: 1987-03-16
Abstract: Levelling boards of this type consist of two hollow profiles capable of sliding one inside the other, namely an outer hollow profile (5) and an inner hollow profile (4). It is thus possible to level beds of different width. The disadvantage is that the transition between the profiles exhibits a step which leads to a non-uniform bed. It is the object of the invention to provide a uniformly extending levelling edge, while preserving the adjustable length adaptation. The object is achieved by a levelling board in which the bottom wall (5a) of the outer hollow profile (5) has an opening (6) which is filled by a projection (7) situated on the downwardly pointing portion of the bottom wall (4a) of the inner hollow profile (4), such that the projection (7) and the bottom wall (5a) of the outer hollow profile terminate flush on the outside. The levelling board can be used in the professional or private building sector for smoothing surfaces. <IMAGE>

Title: Process for producing a curved glazing element
Inventor: REISEWITZ GUENTER
IPC: B29C51/00
Filed: 1987-03-31
Abstract: A process for producing a curved glazing element by heating and forming a thermoplastic ribbed panel having channels consists in covering the edge region of the ribbed panel during heating by a protective frame preventing heating and forming the web panel by the action of compressed air at one side, with simultaneous action of compressed air in its channels, to form the glazing element. The glazing element thus produced has channels open at the edge, so that accummulated condensation resulting from the absence of circulation is avoided. A tool suitable for producing the glazing element consists on the one hand of a lower part (3a) which supports the ribbed panel (1) all round only in its edge region and which has a channel (7) for introducing compressed air into the space between the lower part (3a) and the unsupported surface of the ribbed panel (1), and has an annular channel (5) along the periphery of the ribbed panel (1), and on the other hand of an upper part (3b) which engages in a sealing manner over at least the edge region of the ribbed panel (1) and holds it against the lower part (3a). <IMAGE>
