Patent DE-3834036-A1 (DE)
Inventor: SMITH CYRIL
IPC: G01S11/12
Filed: 1988-10-06
Abstract: A passive rangefinder for use against tanks (20) and like targets and requiring no intervention or action by the operator comprises in one embodiment an infra-red detector assembly (1, 2, 3) producing, in effect, beams (1', 2', 3') within which each detector element is responsive. The beams are arranged so that a target (20) crossing the beams intercepts them at relative time intervals depending on the range. In a variation, two pairs of beams (13, 14 and 15, 16) are produced from detectors (11 and 12) at different ranges, giving different target angular velocities at the two detectors (11 and 12). Again the time intervals give a range indication. The rear beams (15, 16) of this scheme can be folded, by reflection, to present the two detectors at the same location (Fig. 5). In a further variation (Fig. 7) an array of detector elements presents a close array of beams and a full image of the target. Two such arrays at effectively different ranges give different image sizes from which the range is calculated.   <IMAGE>

According to the invention, the covering component (1) has at least one lug (9, 10), which supports the covering component (1) against a radially outer peripheral surface (109) of the carrier plate (35). <IMAGE>
Patent DE-3839991-A1 (DE)
Title: Vehicle gearbox
Inventor: HAGIN FAUST
IPC: F16H47/02
Filed: 1988-11-26
Abstract: The invention proposes a rear-mounted gearbox which is, in particular, suitable for mounting on the rear of a hydrostatic/mechanical split-torque transmission in which two hydrostatic units are arranged close together on both sides of a shaft emerging from the basic gearbox. For a rear-mounted gearbox tailored to these spatial conditions with at least one changeable stage, the proposal is that the gearbox input shaft, the lay shaft and the gearbox output shaft should be arranged one underneath the other and the gear-change devices (multi-plate clutches) for the changeable stages should be arranged on the lay shaft. This gives the shortest overall length of the rear-mounted gearbox, and this can also accommodate in a readily accessible manner a control block with control devices for the hydrostatic units.
Patent DE-3843570-A1 (DE)
Title: Damping device connected between the outlets of two sources of pressure medium
Inventor: SPAETH ROLF
IPC: B60T8/48
Filed: 1988-12-23
Abstract: In brake systems controlled as a function of wheel slip, there is a requirement during control for sources of pressure medium which are capable of building up a high pressure relatively quickly. Due to the high frequency and high pressure, these sources of pressure medium, which are often constructed as dual pumps, produce a relatively loud noise, which can distract the person involved in an emergency situation. It is the object of the invention to improve the damping in a dual-circuit brake system controlled as a function of wheel slip. The object is achieved by means of the combination of features presented in the characterising part of the main claim. In particular, the invention makes an additional contribution to assisting the control process in the case of anti-lock control and traction control and reduces the loading on the conduit material and the cylinders and on the pump itself by reducing the pressure fluctuations. <IMAGE>

Title: Electric flow heater
Inventor: BOGDANSKI FRANZ DR ING
IPC: F24H9/20
Filed: 1989-03-02
Abstract: An electric flow heater has, for switching its electrical heating element (6), electronic switching elements (7), in particular triacs which are switched by a control circuit (8) as a function of the hot water required. So that the control circuit (8) does not destroy the switching elements (7) cooled by the cold water even in the case of comparatively high cold-water temperatures, the control circuit (8) switches off the switching elements (7) irrespective of the hot water required when the current temperature of the cold water pipe (3) or of the cold water for a predetermined time after the flow heater has been switched on remains above a limit value which is insufficient for cooling the switching elements (7). <IMAGE>

Title: Method for cleaning condensers and heat exchangers on the cooling water side
Inventor: ZOERNER WALTER DIPL ING
IPC: F28G9/00
Filed: 1989-03-17
Abstract: Tubes through which cooling water flows in condensers and heat exchangers in the water/steam cycle of energy conversion plants (installations) are subject to various types of contamination on the inner tube surfaces. The reduction this causes in the heat throughput of the tubes is attended by a loss in output of the turbine connected up. Reliable cleaning of the tubes is therefore necessary. According to the invention, the cleaning is performed during operation of the condensers, at least one washing (purging, rinsing) device provided in each water box for a cooling water supply respectively simultaneously covering a group of tubes, which comprises a small number of cubes, and partitioning it off from the water box. In this case, the invention provides that each washing device is supplied with cooling water at an overpressure. The cooling water flows out of the respectively covered tubes at a higher rate than does the cooling water from the water box. Gradually, all the tubes of a condenser are covered and washed under the control of a program without interrupting operations, even in the case of tube plate surfaces which differ on the water-box side. <IMAGE>

Title: Display device for a clock
Inventor: NOSCH GUENTER
IPC: G04B45/00
Filed: 1989-06-06
Abstract: A display device for the course of the hours and of the day provides a clock which exhibits coaxially rotating surfaces (12, 14) having part surfaces (18, 20, 22, 24) of different optical design such that during the interplay of these part surfaces at least one read-off surface (26) is formed which rotates in an analog manner and serves as an information carrier for reading off the time. This read-off surface (26) shows the time in hours (28) and waxes and wanes, in the course of time, this change in the figuration serving as a further information carrier. It is therefore possible to indicate the passage of periods of time without breaking the classic clock principle of analog cycles. The result is a novel clock configuration which not only has been given a decorative aspect but has a functional basis and in terms of its logic corresponds to a modern understanding of the treatment of the phenomenon of time. <IMAGE>
