Patent DE-3147779-A1 (DE)
Title: Flushing cistern
Inventor: GLOECKL ERHARD
IPC: E03D1/22
Filed: 1981-12-03
Abstract: To reduce drinking-water consumption, a flushing cistern is proposed with which it is possible to adapt the volume of water delivered to the flushing requirements. When flushing away solid excrement, a large volume of liquid is delivered, whereas only a small volume of liquid is delivered to flush away liquid excretions. Upon only brief actuation of an actuating button (40), a first outlet valve (34) is opened and a quantity of liquid (A2, C2) is delivered. Part of the quantity of liquid (B2) in the flushing cistern is held back by a separating wall (32). If, on the other hand, the actuating button (40) is pushed a long way through, a pushing member (39) is activated and in addition to the outlet valve (34) a further outlet valve (35) is opened, so that the entire liquid contents flow out of the flushing cistern. In the application, a further four exemplary embodiments with different actuating devices are described. <IMAGE>
Patent DE-3147897-A1 (DE)
Title: Method for the production of annular metal parts
Inventor: NAKAZAWA SHIGEO
IPC: B21K1/04
Filed: 1981-12-03
Abstract: A description is given of a method for the production of a multiplicity of identical annular metal parts from a single blank in the form of a solid rod without forming any holes in the blank and without the necessity of subjecting the blank to a cross-cutting process. The outer circumference of the blank corresponds to the inner circumference of the metal parts to be produced. The blank is first of all compressed in the longitudinal direction, an end region of the blank thus being subjected to upsetting. This gives rise to a laterally expanded region with a lateral circumference which corresponds to the outer circumference of the metal parts and which has a length equal to the thickness of the metal parts. The laterally expanded region is then subjected to a shearing operation along a plane defined by the outer circumference of the blank in order to cut off its circumferential region and thus provide one of the annular metal parts. The blank remains in the form of a solid rod, although somewhat shortened, and can therefore be used for the production of further metal parts by repeating the same steps of the method until the blank is too short. Upsetting and shearing can be performed on the same machine by providing a set of oppositely arranged dies and coaxial punches. It is likewise possible to use the same method to produce annular metal parts with non-circular outer and inner circumferences.
Patent DE-3150580-A1 (DE)
Title: Rescue cell
Inventor: SKOWRONEK ARIBERT
IPC: B63C9/06
Filed: 1981-12-21
Abstract: The rescue cell increases the rescue chances of seafaring crews, which is achieved by the special design of the invention and its assembly on the bridge house. The rescue cell is to be installed above the bridge house on plungers and is to perform all functions of the bridge. The double bottom is used for the statics, stabilises the equilibrium of the rescue cell, holds an emergency unit and the provisions. If necessary, the rescue cell could be released from the ship in three ways:     1. the rescue cell is explosively ejected from the bridge house; 2. if 1. fails, the locking mechanism would be released by the buoyancy upon floating of the rescue cell; 3. if the ship lists heavily, the rescue cell would slip into the water, since the steel of the plungers would shear off after a certain time. Thus the invention can be launched even during the most extreme positions of the ship; it can even be released from the ship during sinking.

Patent DE-3237310-A1 (DE)
Title: Radio transmission path
Inventor: FUENTE PEDRO DE LA
IPC: B61L3/12
Filed: 1982-10-08
Abstract: In the wireless transmission of information between a receiving station in a track-bound vehicle and fixed-point transmitting stations, the problem arises of supplying the transmitting stations with power in an economical and reliable fashion. The method proposed here uses a signal transmitted from the mobile receiving station for supplying power to the fixed transmitting station and also the carrier signal, to which the information of the fixed transmitting station is added by modulation and which is then radiated back in the direction of the mobile receiving station. The signal transmitted from the mobile receiving station can be provided with auxiliary modulation in order to identify clearly the polling receiving station. If a band-spreading method is used for the auxiliary modulation, the immunity to interference of the transmission can be further increased.

Title: Drilling tool for producing undercuts in pilot holes
Inventor: DUSS OTTO-EUGEN DIPL ING
IPC: B23B51/00
Filed: 1983-01-08
Abstract: The rotationally drivable tool shank is formed by a shank sleeve and by a shank bolt mounted in the shank sleeve in such a way as to be axially displaceable to a limited extent. Radially working tools (radial tools 14) are pivotably mounted in diametral slots (16) of the shank sleeve (11). Axial percussion impulses of a rotary percussion hammer are converted into radial percussion impulses of the radial tools (14) by means of a tapered end section (10a) of the shank bolt (10). Relatively blunt, insensitive reaming members can thereby produce an increased reaming performance at a low rotational speed (Fig. 1).

Title: Silo for bulk felting material, such as wood chips or the like
Inventor: ZIRNGIBL EKKHART ING GRAD
IPC: B65G65/46
Filed: 1983-02-05
Abstract: In silos for bulk material, such as wood chips or the like, there is provided in the lower region a rotating agitator arm which loosens the material and which conveys it towards a discharge point. Where some materials, such as wood chips or the like, are concerned, a felting or entanglement of the material can occur in such a way that a solid bridge forms over the agitator arm and therefore a large proportion of the material located in the silo is not conveyed out. To solve this problem, it is proposed to design the silo (1) with a first rotating agitator arm (14), in such a way that a further agitator arm (19) extends obliquely towards the outer circumference (9) of the silo from the middle (22) of the top side (23) of the housing (2) of the silo (1). The further agitator arm (19) can be connected to an independent drive (27) or to the first agitator arm (14) via a joint (17). <IMAGE>
