Patent DE-3114227-A1 (DE)
Title: Garment
Inventor: DRESSLER HEINZ DIPL KFM
IPC: A41D1/14
Filed: 1981-04-08
Abstract: In the case of this garment, which is equipped with a hip band, there is provided an inner pocket (40) which is only accessible from the inside. So that this pocket cannot be recognised as such by the uninitiated at first glance, and so that objects stored therein cannot fall out of it, the lower edge (44) of the hip-band lining (36) is designed to be of sufficient width underneath the lower band seam (38) that it extends over the pocket opening (42) and conceals it. Since the lower edge (44) of the hip-band lining (36) is not sewn down, when it is bent up it exposes the pocket opening (42). The inner pocket (44) can be designed in different forms. If it is designed as a purse-type pocket (40), a label (46) can be provided on its visible surface, giving the impression that it is not a pocket but a labelling tab. <IMAGE>
Patent DE-3117010-A1 (DE)
Title: Cylinder lock
Inventor: CASTALDO JERRY L
IPC: E05B27/04
Filed: 1981-04-29
Abstract: A cylinder lock, which can be actuated by two different keys, is provided. A main key can be used for locking and unlocking the lock. An auxiliary key can be used only for locking the lock. The lock has pin-shaped tumblers, the cylinder having a shallow step recess in the region of a pin chamber. The auxiliary key is identical to the main key, with the exception that one or more of the drop-in notches of the auxiliary key are cut deeper than the corresponding drop-in notches of the main key. The additional depth corresponds to the depth of the step recess. When the main key is inserted into the key guide of the cylinder, the pin tumblers are lifted in the normal way until the plane of contact of the pins is aligned with the shearing line between the cylinder circumference and the case. The plug can then be rotated in both directions. However, when the auxiliary key is inserted into the key guide, one pin tumbler or a plurality of pin tumblers are lifted only until the plane of contact of the pins is at a point below the shearing line, but level with the bottom of the step recess or somewhat above it. The cylinder can thus be rotated in only one direction, so that it is possible for the lock to be locked with the auxiliary key, but an unlocking of the lock is not possible.

Patent DE-3132212-A1 (DE)
Title: Solenoid valve
Inventor: ZILLING HELMUT DR
IPC: F16K37/00
Filed: 1981-08-14
Abstract: In solenoid valves equipped with a main cone and a preliminary stroke cone mechanically coupled to the latter, there is the risk that the mechanical coupling will fail. It was hitherto impossible to detect this from outside. Even an indicating device for the valve position gave no indication of such a fault. On the contrary, it gave a false signal: even though the main cone, which had come away from the preliminary stroke cone, was still in the closed position, its open position was indicated. The invention eliminates this deficiency by means of a position indicator (14) which interacts with the actuating rod (3) of the solenoid valve and which responds in the case of a position above that of the normal opening stroke. Thus not only is clear information provided as to the open position of the main cone but faults in the coupling are also indicated. <IMAGE>

Title: Method and device for generating a television image or film with plastic image impression
Inventor: HILF PAUL
IPC: H04N13/00
Filed: 1981-11-13
Abstract: The present invention proposes a method, known per se, for producing postcards with plastic effect, in order to generate a plastic television image by scanning vertical television lines of a stereo image. The method for scanning the vertical television lines and for generating the stereo image is shown by means of an illustrative embodiment in Figure 5. Each stereo image is composed of individual image strips, such a strip in each case being written with three television lines. An unintentional jumping of an electron beam from the lines of one image strip to the adjacent one is prevented by applying a shadow mask. To achieve adequate accuracy of reproduction and high resolution, it is necessary to choose a suitable electron beam focusing to the smallest possible image diameter of the luminous spot, also a sufficiently large number of image strips/cm to be transmitted per frame and an adequate magnitude of the vertical line number generating each image strip.
Patent DE-3146645-A1 (DE)
Inventor: BETHMANN KARL WILHELM DIPL ING
IPC: F42B8/14
Filed: 1981-11-25
Abstract: In ammunition, preferably for machine cannons, including a subcaliber stabilized projectile equipped with a body of tracer material and a stabilizing element, the heat released during combustion of the tracer material is utilized to drastically change the strength of the material of an element used to fasten the stabilizing element to the projectile. By being able to set the time of combustion and of the change in the material, the stabilizing element changes its position with respect to the projectile. The system or ammunition in question becomes unstable and drops to the ground.

Title: Circuit arrangement for the controlled voltage supply of power-fed terminals in telecommunication and particularly telephone systems
Inventor: DRAGOTIN ALEXANDER DIPL-ING
IPC: H04M19/00
Filed: 1981-12-23
Abstract: As a part of the respective terminal (EG), there is a switched-mode controller coupled to the subscriber line by means of which the feed current for the functional units (BE) contained in the terminal is provided at the required amplitude with a constant supply voltage. Due to the transformer effect of the switched-mode controller, the line current is distinctly less than the current consumed by the functional units in the terminal. Due to the fact that the transmission losses are consequently reduced, the supply power available in the terminal rises. Instead of the diode usually also forming the switched-mode controller, a field-effect transistor (T2) is present. Particularly with respect to the provision of feed power for digital terminals, the switched-mode controller operates with constant pulse width and free-running switching frequency which adjusts itself in dependence on the loading in the idling state whereas the switched-mode controller is pulse width controlled in the other operating conditions. To reduce the interference effect in these operating conditions, the operating switching frequency approximately corresponds to the transmission frequency used with a digital terminal. The switched-mode controller is then synchronised to the frequency of the operating clock effectively output by a clock generator, starting from the correspondingly much lower clock frequency in the idling state. <IMAGE>

Title: Drive for washing machine drum
Inventor: FUNKE WALTER
IPC: D06F37/36
Filed: 1982-01-21
Abstract: The invention relates to a drive for a washing machine drum with wash and spin gear. Drives of this type are needed in order to be able to control the differing number of revolutions of the washing machine drum between wash and spin gear by simple means without any interruption and to give the wash gear reversible directions of rotation. In known drives of this type the electric motor of the wash gear is brought to an essentially higher speed by the electric motor of the spin gear, which places an unnecessary load on the drive system and increases the susceptibility to breakdown. Furthermore, in reverse switchings of the wash cycle by way of a reversible free wheel relatively hard reversal occurs, which also increases the tendency to breakdown. The object of the invention is to improve the drive in that a centrifugal force switching device (8) transmits the drive for the slow wash cycle by frictional resistance at low speeds, but uncouples the preconnected slow electric motor (2) when the high-speed electric motor (4) for the spin gear is switched on. <IMAGE>
