Patent DE-3828621-A1 (DE)
Title: Arrangement for producing a defined gap between tool and parts in pulse soldering
Inventor: ZIMMER GERO
IPC: H05K3/34
Filed: 1988-08-23
Abstract: A description is given of an arrangement for automatically producing a defined gap and/or defined parallelism between a first and a second part, in which case these parts can be kept at a defined distance from one another with automatic tolerance compensation. Arrangements of this type are used, for example, for the heat treatment of a part for soldering tasks, for adhesive bonding, etc. For this, at least one of the surfaces is provided with one or more mechanical supports which strike the second surface in a non-positive manner preferably outside the opposite surfaces. By control of the force of the individual supports on the other surface via, for example, an individual device or via a floating device, the preset gap is ensured, irrespective of the actual original parallelism of the two parts to one another.
Patent DE-3831623-A1 (DE)
Inventor: HERO WERNER
IPC: F16L59/20
Filed: 1988-09-17
Abstract: For the joining of heating pipes (1; 2), which are composed of a medium pipe (3) made of steel, a jacket pipe (4) made of plastic and foam filler (5) in between, the medium pipes (3), which are exposed at the ends, are welded (6) in a known manner. A bridge (8) is then placed over the gap between the foam fillers (5) and supported on the two previously exposed ends (7) of the foam fillers. The bridge (8) is composed of a sideways U-shaped profile made of aluminium sheet; its arms are pressed into the foam. The gap between the jacket pipes (4) is then closed by flush insertion of a jacket pipe transition piece, the transition piece being connected to the two adjacent jacket pipes (4) by seams, in particular welded seams, and being closed at a longitudinal section. In this case, the bridge (8) serves as a support on said longitudinal section so that the transition piece does not shrink and sink in due to the heating on the longitudinal seam. Subsequently, the cavity is filled with foam. <IMAGE>

Title: Method for the detection of the centre of a laser beam projected by a levelling device (so-called construction laser) by means of at least two laser-sensitive signal-transmitting receiving elements arranged in a mirror image about a "zero line", and device for carrying out the method
Inventor: MENDE ERNST WILHELM
IPC: G01C15/00
Filed: 1988-09-29
Abstract: The invention relates to a self-calibrating receiving device for the accurate detection of the centre of a laser beam projected by a levelling laser device (so-called construction laser), this laser beam generating a control signal when it impinges on any one of the photodiodes (5a, 5b) above or below the "zero line" (19). On the basis of these signals, the slide (4), on which the photodiodes (5a, 5b) are arranged in a mirror image about the fixed "zero line" (19), is displaced automatically by a servo motor in one direction or the other until the centre of the projected laser beam impinges exactly on the "zero line" (19) (= lined-up condition). This lined-up position is indicated optically by means of a light-emitting diode (17) and/or acoustically by means of a buzzer (20). A marking-out scale (9) is arranged at right angles to the displacement direction of the slide (4) in such a way that its upper edge (21) lies exactly at the level of the "zero line" (19) and serves as a marking-out edge so that, after reaching the lined-up condition, the zero level transferred by the projected laser beam can be marked out on the wall. <IMAGE>

Title: Variable valve overlap for four-stroke engines by means of intermediate gearing with adjustment
Inventor: MAGER GERD
IPC: F02D13/02
Filed: 1988-12-15
Abstract: In order to bring four-stroke engines up to a higher specific output but at the same time to a lower partial load consumption, the values for the start of inlet and exhaust, fixed in conventional engines, are designed to be variable in that an intermediate gearing is connected to the relevant camshaft on the input side. The said gearing comprises two identical gears with n teeth and two likewise identical gears with m teeth. An m-toothed and an n-toothed gear are rigidly connected to one another and rotatably mounted in an adjusting lever. The two other gears lie coaxially in tandem and represent the drive and output side respectively. The pair of gears supported in the adjusting lever meshes on one side with the gear of the output side and on the other with the gear of the drive side. Rotation of the bearing lever about the centre point of the gears of drive and output side causes a phase offset of the rotational movement between drive and output side.

Title: Noise-suppression arrangement for digital video signals
Inventor: HIRATA TORU
IPC: H04N9/64
Filed: 1989-03-30
Abstract: The invention relates to a noise-suppression arrangement for reducing or suppressing interference signals ("noise") contained in a digital video signal. A two-picture (field) differential detector unit (27) receives the digital video signal and detects a two-picture (field) differential signal. A high-frequency-component filter unit (22) filters a high-frequency component of the digital video signal or a high-frequency component of the two-picture differential signal. A first suppression-signal generator unit (28) generates a first suppression signal corresponding to the two-picture differential signal. A (field) picture differential detector unit (32) receives the digital video signal and detects a picture differential signal. A low-frequency-component filter unit (23) filters a low-frequency component of the digital video signal or of the picture differential signal. A second suppression-signal generator unit (33) generates a second suppression signal corresponding to the picture differential signal. A noise-suppression unit (24, 30) removes the interference signal from the digital video signal in accordance with the first and second suppression signals. <IMAGE>

Inventor: FILBERT DIETER PROF DR ING
IPC: H03H19/00
Filed: 1989-06-16
Abstract: In a filter, filter input signals (u(t)) are modulated on a carrier signal (p(t)) with a carrier frequency (fo) via a multiplier (M1) and taken to an input (E1) of a SAW convolver (C). A sine-wave signal (v(t)) with a predeterminable frequency is also modulated on the carrier signal (p(t)) via a second multiplier (M2) and taken to a second input (E2) of the convolver (C). The output signal (A) of the convolver (C) represents the folding product of the input signals. The sine-wave input signal (v(t)) is taken via a retarder (VZ) to an input (5) of a further multiplier (M4) which also receives at its input the synchronously demodulated output signal (g(t)) of the convolver (C). The filter has a band pass characteristic with a very rapidly variable median frequency in wide ranges.

Title: Concrete paving slab - has projections formed along edges which fit between projections on edges of adjacent slabs
Inventor: HERZ LUTZ
IPC: E01C5/06
Filed: 1989-11-11
Abstract: The concrete paving slabs are formed with a line of projectins along each edge.  Each projection has a flat crest (2) and sloping sides (3).  The projections (1) are so spaced that the projections of one slab fit into the spaces between projections of the adjacent slabs. Relative sideways movement between adjacent slabs is thus prevented. The slabs are produced in a press which produces a textured pattern on the upper surface (5).  The press operates so that an additional pressure is applied to the slab edges (4) and projections which results in the concrete in these regions having a higher strength than the concrete in the rest of the slab.
