Patent DE-3827765-A1 (DE)
Title: Missile which is provided with a warhead
Inventor: SEIDENSTICKER JENS DIPL PHYS D
IPC: F42C13/02
Filed: 1988-08-16
Abstract: In the case of missiles (1) having IR detectors (7) which are used for attacking airborne targets (4), the problem frequently arises of the missiles (1) flying past the target (4) because heat sources (ground vehicles, fires etc.) further away have also been detected. In order to avoid this disadvantage, the invention proposes the use of an additional IR detector (8) which receives radiation in the quasi-non-transparent spectral section of the atmosphere (for example 5 to 8  mu m or > 14  mu m). This second IR detector (8) is then connected to the first IR detector (7) via a coincidence circuit (205) so that detonating signals are produced by the coincidence circuit (205) only when the missiles (1) are in the vicinity of the airborne target (4). <IMAGE>
Patent DE-3832474-A1 (DE)
Inventor: ROSSE CLAUDIO
IPC: F24F1/005
Filed: 1988-09-23
Abstract: The device (1) comprises a partition (9) supported by two circular sectors (10) provided with a peripheral rack (13) operated by an electric motor (16) effecting their movement in opposition to return springs (19). The positioning of the rack (9) closes one of the intake paths (3, 7) of an environment conditioning unit (1), enabling it to draw in air from the environment (4) in which it is installed or else to introduce conditioned air (8) present under the raised floor (2) of the environment. An adjustable stop wedge 22 allows intake of small amounts of air from under the floor even when the intake path 7 is closed. <IMAGE>

Patent DE-3839691-A1 (DE)
Inventor: FRANCHINO MAURO
IPC: F02M1/10
Filed: 1988-11-24
Abstract: A membrane 22 when subject to manifold vacuum in a chamber 21, e.g. when an engine coolant temperature responsive valve (4 Fig 1) is open at low temperatures, abuts an adjustable screw 24 through its centre element 23,44. A valve 37 in the element 23 is opened by the vacuum which is transmitted to a chamber 27 and a membrane 28 connected to a throttle valve opening rod 7 is moved to a position determined by the element 23 to provide a rod stroke C1. When vacuum is applied directly to the chamber 27, e.g. when the coolant temperature valve (4, Fig 1) is closed and an electrically operated valve (6) is opened, the membrane 22 is moved until its support plates 33 abut the actuator body 17 at 25 and the rod stroke is reduced to a lower valve (C2, Fig 4). <IMAGE>
Patent DE-3841174-A1 (DE)
Title: Propeller fan
Inventor: KASTENS KARL DIPL ING
IPC: B64C11/48
Filed: 1988-12-07
Abstract: Figure 1 of the attached drawing set relates to the development of the propeller fan as is described in the Main Application P 3734624.5-22. A preferred feature of this development is that the flow guidance body 1 which coaxially surrounds the connecting spar 19 but is partially open is designed such that it can pivot in that the struts 2, which are connected to it, are mounted according to the detail E such that they can rotate in the gas outlet housing 5. The vertical thrust vector KV can in this case be displaced as far as the horizontal so that it is then parallel to the pitch axis and thus ensures maximum lateral acceleration of an aircraft. The suspension of the propeller fan between the first and the second mainplanes 17 and 18 requires a capability to compensate for thermally dependent length changes of the front and rear fan stators 12 and 13. This is done by means of a pin 20, which is fitted displaceably in the front fan stator 12 according to the detail D and to whose streamlined pin head 29 the lower holder 14, which is fastened to the mainplane 17, is firmly connected. <IMAGE>
Patent DE-3844370-A1 (DE)
IPC: A45D24/22
Filed: 1988-12-30
Abstract: A device for release and/or absorption of a liquid comprises a number of stratified thin plates and/or films with slit-shaped gaps between the individual plates and/or films. The dimensions of the slit-shaped gaps are such that the liquid to be released or absorbed flows through the gaps by capillarity in function of the material of the plates and/or films and of said liquid. To increase the quantities of fluid, which may contain small solid particles, transported by capillarity and to permit a wide range of new applications at considerably lower cost, the device is designed as a freely movable, easily manipulated utility article or tool for applying/removing liquid to/from surfaces by stroking the latter. To this end, the stack of plates and/or films has at least one lateral surface which acts as a liquid-releasing or liquid-dispensing surface and the other regions of the stack of plates and/or films constitute a liquid reservoir.
Patent DE-3902163-A1 (DE)
Title: Method and apparatus for strengthening a container seam
Inventor: FRICK RENE
IPC: B23K26/28
Filed: 1989-01-25
Abstract: A container seam (20) is formed by jointly bending at least once a casing margin (16) and a base margin (18) from an originally radial direction into an at least approximately axially parallel direction. The container seam (20) has a free end face (22) at which the base margin (18) arches over a sharp bend (24) of the casing margin (16). An annular rolled path (30) of rectilinear profile in axial section through the container (10) is produced on the end face (22) of the finished seam (20) by the rolling contact of at least one rolling body (28). The rolling contact takes place with such pressure that the sharp bend (24) of the casing margin (16) is also flattened in the process. At least two parts of the margins (16, 18) resting one on top of the other are then welded to one another by means of an energy beam (32), in particular a laser beam. In the process, the energy beam (32) is directed at least approximately at right angles onto the profile of the rolled path (30). <IMAGE>
Patent DE-3906553-A1 (DE)
Title: Screening electrode
Inventor: NIEMEYER LUTZ DR
IPC: H02G5/06
Filed: 1989-03-02
Abstract: The screening electrode (for example 9) is intended for an insulator (6) which supports a conductor (8), which carries high voltage (high tension), with respect to earth potential. It has a bearing surface which is at earth potential or at the high-voltage potential. This screening electrode is intended not only to relieve contact points (H, K) between the insulator (6) and the live part of the effect of the electrical field but, at the same time, also largely to avoid any undesirable interference-arch discharge passing via the screening electrode. This is achieved by means of a screening electrode (for example 9) which consists largely of an electrically insulating material having a dielectric constant which is high in comparison with that of the insulating material of the insulator (6). <IMAGE>

Title: Method and device for metering free-flowing substances, especially liquids, by pouring out from a container which is open at the top
Inventor: FREINSHEIMER GERD
IPC: G01G13/22
Filed: 1989-04-05
Abstract: In a method for metering free-flowing substances, especially liquids, by pouring a desired quantity out of a container which is open at the top, in which the container held vertically with its opening upwards is tilted and the container content is caused to run out over the edge of the container opening, whereupon after pouring out the desired quantity the container with its remaining content is tipped back and the outlet stream is thereby interrupted, it is provided according to the invention that the container is lifted up before the initiation of the tilting process and its gross weight is determined, whereupon the tilting process is initiated in an accelerated manner and is continued until the desired quantity established as a net weight has run out, whereupon the tilting movement is decelerated and is tracked to the running out of the container content, and that the tilting back of the container upon reaching the container gross weight reduced by the desired quantity is accelerated until the interruption of the outlet stream is carried out.

IPC: G11B20/18
Filed: 1989-08-21
Abstract: Coding process. Reed Solomon coders are used to code audio signals which are recorded on a CD in accordance with the CD standard. First parity symbols are produced in a retroactive shift register. To obtain a simple circuit, the first parity symbols are shifted from the retroactive shift register into a storage shift register. After a given number of cycles, the direction of data flow in the storage shift register is reversed. During read-out of the parity symbols, the parity symbols calculated in the retroactive shift register (S1,..., Sn) are combined with those of the storage shift register (R1,..., Rn) in an adding device (A2). Process for coding audio signals which are recorded on a CD or on a magneto-optical disk in accordance with the CD standard.
