Inventor: STURTZEL JORG FELIX
IPC: G01S7/295
Filed: 1991-09-16
Abstract: A process for displaying radar echo signals allows brightness modulation signal of the radar picture to be derived from the radar echo signal. In order to avoid brightness overmodulation in the case of flat, wide echo structures, and to improve detail recognition, the flat echo structures of extensive reflecting objects that appear on the radar picture are reproduced around their outer outlines (contour) with high intensity, whereas the inside of their surface is reproduced with a strongly reduced intensity. A highly contrasted image with a cartographic appearance is thus obtained, in which even smaller targets or targets with bad reflecting properties, thus lower intensity, can be very well recognized.

Title: Re-order system for pictures and transparencies developed from film strip sections - has strip sections wound on roller and then further unrolled in printer and protective foil strip runs are located between layers of individual film strip sections
IPC: G03B27/62
Filed: 1991-11-21

Patent DE-4201556-A1 (DE)
Inventor: EBERT CLAUS
IPC: A47B13/08
Filed: 1992-01-22
Abstract: A table top made of plastics is designed as an extruded profiled piece made of integral skin foam and cut into lengths, and has at least one longitudinal profiled marginal flange (20) formed in a single piece. In addition, several longitudinal ribs (22) are formed on the same side which delimit, in the same way as the marginal flanges (20), cavities (24, 28) with an open cross-section. The particular form of the table top makes it possible to obtain a table top with a very reduced thickness and very low weight, depending on the material of which it is composed. Metallic sections may be inserted in the cavities for reinforcement purposes, and are also useful for mounting table legs, frontal sealing flanges and other parts of a worktable. Thanks to the design of the profiled marginal edges in a single piece, the complicated state-of-the-art postforming manufacture process can be dispensed with.

Title: Chuck with switchable centrifugal force compensation - has distance piece in form of U-slotted disc that is turned through 180 deg. to disengage end of compensating force transfer lever from chuck jaw
Inventor: GULDE SIEGFRIED
IPC: B23B31/177
Filed: 1992-03-06
Abstract: The adjustable jaws (10) of the chuck each have a centrifugal force compensating weight (12) which, as the speed increases, exerts an outwards radial force on the end (16) of the lever (15). This is transformed into a magnified inwards force on the jaw by contact of the opposite end (17) of the lever on the U-shaped recess (21) on the inner surface of a rotatably adjustable disc (18). In one position of the disc, the open end of the U faces outwards and the force is transmitted to the jaw. With the disc turned through 180 deg., the open end of the U faces inwards and the force is not transmitted. A spring-loaded ball detent prevents accidental movement of the disc. ADVANTAGE - Excessive clamping force on fragile workpieces when spindle is braked can be avoided by switching out compensating force.

Abstract: The circumferential surface of the combination of two discs (2,3) pref. of polyoxymethylene is shaped with a U-section recess into which the excess lengths of lightguide (20,20') are taken up. Each disc may be either circular or elliptical with a wedge section bar (4) upstanding between two slots (11) at each end of a take-up region (19). Automatic unwinding is prevented by heads (9) projecting into the centre of the recess from opposite sides. ADVANTAGE - Fibres have better access to take-up region, esp. of elliptical device having no edges in winding area, and splices are protected within flattened curvilinear portion.

Title: Surveillance device for display window, showcase - gives alarms on interruption of optical pulse reflection from window having non-reflected portion exposed in its open position
Inventor: OTT REINHOLD
IPC: G08B13/181
Filed: 1992-04-09
Abstract: The security device determines if the window in e.g. a showcase is closed by detection of the light emitted by a source and reflected from the window in its closed position to a sensitive photodetector. The emission of the light from the source is timed in single pulses of a particular duration and repetition rate. The detector incorporates a device for recognising the shape of the reflected pulse. When the window is open, the light falls on an opaque and non-reflecting area. ADVANTAGE - Pulsation of light source, at rate imperceptible to human eye, guarantees alarm function against interference from daylight or attempted manipulation using pocket lamp.

Patent DE-4228721-A1 (DE)
Inventor: RUHLMANN RENE PHILIPPE
IPC: F24D3/16
Filed: 1992-08-28
Abstract: Acoustic and/or cooling and heating ceilings for rooms present problems with regard to their appearance insofar as it is not possible to do without expansion joints when cementing in the heat exchanger (6) on the ceiling (2); but also between the joints, the stability of the cementing-in is always at risk. Even in the case of free suspension and cladding by means of covering panels, the difficulty remains that the grid of the covering panels is visible. Provision is therefore made to design the covering panels as acoustic and/or heat-insulating panels (5) and, as required, lay them between the sheet-like, meandering, tubular heat exchanger (6) and the ceiling (2), so that at the same time the ceiling (2) is insulated, and to cover the heat exchanger (6), the heat-insulating panels (5) and the necessary holding fixtures with a plastic sheet (8), which is secured on the walls of the room, but is additionally joined over its area to the acoustic and/or heat-insulating panels by means of nails, pins or the like (10). A perfect undersurface is obtained by spraying over the entire arrangement. <IMAGE>

Patent DE-4233273-A1 (DE)
Inventor: CROWLEY PATRICK JOSEPH
IPC: F02M47/02
Filed: 1992-10-02
Abstract: A common rail fuel injection system for an I.C. engine consists primarily of a high-pressure piston pump (224 or 226), nozzles (40, 42, 44 or 52, 54, 56), and a corresponding rail (28 or 30) held at a substantially constant pressure and connected between the fuel pump and the nozzles. An electronic system 10 controls the nozzles and an inlet fuel pressure valve 274 controlling the supply of fuel to the pump. Fuel flows from the valve 274 past an inlet ball valve 237 urged to its closed position by a spring 245 when the pressure differential is sufficient and an inlet port 238 is exposed by the piston 234 during its suction stroke. Control valve 274 may be of the variable or fixed orifice type. Fuel leaking past the piston 234 and fuel collected from the nozzles is received in an accumulator chamber 264 and fed into the pumping chamber 232 during each suction stroke. Thus the total amount of fuel pumped is reduced and metering accuracy improved. <IMAGE>
