Title: Locating display for defective lamps in airport navigation lights - couples pulse signal inductively into mains supply if lamp current or voltage drop is sufficiently low
Inventor: STIMPER KLAUS DR ING
IPC: H05B37/03
Filed: 1991-12-27
Abstract: The navigation lights in an airport are supplied by the secondaries of a set of transformers (2) whose primaries (1) are all in series and supplied from the mains. For each individual lighting circuit, a current transformer is used for measuring the lamp current. Another sensor measures the voltage drop across the lamp. Current and voltage are compared with preset limits to see if either a short circuit or an open circuit has occurred. If so, a warning device generates positive or negative impulses in the circuit which are inductively coupled (by the main transformer) into the mains supply. The output signals of first (8) and second (9) window comparators are supplied to an XOR gate (10) releasing an alarm signal. A suitable decoder can then be used to evaluate the pulse signal for fault location and mechanism. ADVANTAGE - Location of defective lamps without needing separate circuit.

Title: Test equipment for roundness of discs rolling down inclined plane - allows passage of single disc past acutely angled linear image sensor long enough for scan of complete circumference
Inventor: MEITINGER HEINZ
IPC: G01B21/20
Filed: 1992-09-14
Abstract: A linear image sensor (1) is placed at an acute angle to the direction of movement of the discs (2) as they roll down the plane (5) past a row of nozzles (6), from which jets of air emerge to reject any disc failing the test of roundness. A slider (7) positioned as close as possible to the image sensor releases one disc at a time so that it passes through the scanning region with limited speed. The image processing is conventional as in DE3312983. ADVANTAGE - The entire circumference of each disc can be checked with sufficient accuracy, and any departure from roundness is recognisable from the irregularity of movement.
Patent DE-4235530-A1 (DE)
Title: Compact sheets e.g. thermo-formed
Inventor: TESCH GUENTER HORST
IPC: B32B37/24
Filed: 1992-10-21
Abstract: Moulded article is made of particles of thermoplastics, and of plastic films in partic., by bonding them together under heat and pressure with pieces or strips of cellulosic material. The surface of an example is made by hot pressing pieces (1) of plastic and/or plastic films (2) plus pieces (3) of cellulosic material. The pieces (2,3) concerned are bonded together, whilst they are still visible in the structure formed e.g. in relief. The pressed sheet contains air occlusions. The surface particles of plastic material (2) become fused together so that blurred areas are formed (4) with different colours. If the product is thermoformed the blurred effect is heightened by the additional heating at the surface and the enveloped pieces of paper used. The latter then become no longer recognisable. The prod. can be moulded into corrugations, e.g. to carry cables along the depressions.

Patent DE-4301417-A1 (DE)
Inventor: GROCHOWSKI EDWARD T
IPC: G06F9/30
Filed: 1993-01-20
Abstract: A dual instruction decoder issues two instructions in parallel within a single clock cycle if there are no register dependencies between the instructions, and if both instructions fall within a predetermined subset of the complete instruction set. A first pipeline executes any instruction issued from the full instruction set, while a second pipeline only executes a predetermined subset of instructions determined by principles of locality. A register dependency checker determines whether the designation register of a first instruction is used during the execution of a second instruction in an instruction sequence. When both instructions are within the subset and there are no dependencies, the first and second instructions can be issued in parallel in the first and second pipelines. <IMAGE>
