Title: Self-advancing tunnel reinforcement system - comprises series of cylindrical sections connected end-to-end by traction and thrust jacks
Inventor: UEMURA KOICHI
IPC: E21D9/00
Filed: 1980-09-01
Abstract: An underground structure such as a tunnel is constructed by advancing a series of bodies arranged end-to-end, one-at-a-time. Between certain of the bodies are disposed advancing mechanisms such as pulling/traction jacks (2) and thrusting jacks (3). Connecting members (4) in conjunction with fasteners (6) and traction members (5) in conjunction with fixing pieces (7) may be used selectively to link together certain groups of the bodies so as to allow their advancement one-at-a-time. The advancing mechanisms the fasteners and the fixing pieces are selectively operated such that when one body is being advanced, at least two other of the bodies (or one other body and a fixed mechanism) provide a reaction to the force required to advance the one body.

Title: Asbestos cement type facade panel self tapping screw - has enlarged cutting section below head, for making larger holes
Inventor: KNOCHE FRANK
IPC: F16B25/10
Filed: 1980-11-18
Abstract: There is a thin threadless shaft section below the screw head. The OD of the threaded section is increased in the area of the end facing the head. The self-drilling screw is used for fixing external wall-facing panels, such as those of asbestos cement, on a substructure. Below the screw head, spaced according to facing panel thickness, there is a likewise self-tapping cutting section, of larger OD in relation to the screw thread. This can be formed by a sleeve socket set on the thread of the screw, with cutting edges on it. Stops for this can be pressed on the shaft, at intervals equal to the panel thickness.

Abstract: The invention relates to an apparatus for connecting pipes in a double-pipe milking machine, in the case of which the milk pipe is situated and held inside a low pressure pipe. A low pressure chamber is formed by a connecting casing which is composed of two parts, in which low pressure chamber the low pressure pipes are connected to one another in an airtight manner. The ends of the milk pipes, on the other hand, are connected to one another within a chamber which exhibits external pressure and is separated from the low pressure chamber by means of a partition, sealing materials being mounted between the partition and the external circumferential surfaces of the milk pipes.
Patent DE-3116719-A1 (DE)
Title: Device for the venting of a liquid tank, especially a fuel tank of motor vehicles
Inventor: SCHEURENBRAND DIETER
IPC: B60K15/035
Filed: 1981-04-28
Abstract: A device is proposed for the venting of a fuel tank, which has an equalising vessel arranged in the upper area of the tank chamber, which vessel is vented to the atmosphere by way of a pipe arranged approximately centrally. At the end the equalising vessel is connected to a cage arranged in the area adjacent to a tank end wall running in the longitudinal direction of the vehicle, in which a ball is freely held. At the same time the cage is connected both to the inside of the tank by way of an aperture running in the vehicle transverse direction and to the equalising vessel by way of a single aperture arranged in a plane lying in the vehicle longitudinal direction, as can be seen from Fig. 1. When the tank is in an inclined position, the ball, due to the effect of centrifugal force, closes the cage aperture running in the vehicle transverse direction and, when the tank is at roof level, said ball closes the aperture arranged in the plane lying in a vehicle longitudinal direction due to the action of inertial forces. <IMAGE>

Abstract: Method for regulating the flow rate of a compressor installation whose compressors deliver into a pressure vessel whose pressure is regulated between an upper switching pressure and a lower switching pressure. When the upper switching pressure is reached, the compressor installation is either, depending on the previous charging time, switched to unloaded running or is shut down. In order to limit the frequency of the start-up operations required after shutting down, a reference time interval is predefined and within each reference time interval only one shut-down is permitted.

Title: Spherical puzzle
Inventor: KOBBERT MAX J PROF DR
IPC: A63F9/08
Filed: 1981-07-14
Abstract: The three-dimensional puzzle in spherical form is particularly suitable as a mind game. An external hollow sphere (HA) is subdivided into segments with multiple intersections which thus break it down into numerous individual parts. The parts are fixed on an inner sphere (HI) so that some of them can be rotated, while some of them are mounted on HI by overlapping or ridge connection. By alternately rotating the segments, the parts are mixed while the sphere as an overall shape is retained. In one example of embodiment, HA is subdivided by four great circles into six quadrilaterals and eight triangles, half of which forming a hemisphere, and the connection of the parts being provided by overlappings. The drawing shows the example of embodiment broken down into HI and two halves of HA, and one of the four pins (Z) by means of which four triangles are rotatably fitted onto HI in the assembled puzzle. <IMAGE>

Patent DE-3130171-A1 (DE)
Title: Device for shutting off an internal combustion engine
Inventor: INDRA JAROMIR DIPL ING
IPC: F02M63/02
Filed: 1981-07-30
Abstract: The invention solves the problem of shutting off an internal combustion engine when the key in the control box is turned into the STOP position. In known devices of this type, the electrical current, which feeds the coil of the solenoid valve when the internal combustion engine is running, is shut off when the key is turned into this position, the valve then closing due to the action of a preloaded spring, thereby preventing the free flow of fuel, which flows out of the reduction valve of the low pressure circuit of the injection device, and conducting all fuel delivered by the feed pump into the hydraulic drive, the piston of which, due to the pressure of the fuel, pushes the control rod into the STOP position, thereby shutting off the internal combustion engine. The known device has a high energy requirement, because electrical current flows through the coil of the solenoid valve when the internal combustion engine is running. The essence of the invention consists of the fact that when the engine is running the coil of the solenoid valve is currentless and only when the key is turned into the STOP position is the electrical current fed to the solenoid valve for that length of time absolutely necessary for shutting off the internal combustion engine. The invention can be used in particular on internal combustion engines for vehicles and in those cases in which shutting off the internal combustion engine by mechanical means is difficult. <IMAGE>

Title: Manufacture of double cigarettes
Inventor: AHERN RONALD ALBERT
IPC: A24C5/52
Filed: 1981-12-08
Abstract: The invention relates to the manufacture of double cigarettes, each of which consists of a double-length tobacco rod to whose opposite ends filters are attached. The severing of the double cigarettes to produce separate filter cigarettes can be delayed until immediately before the packaging of the cigarettes, so that the filters at the ends of the double cigarettes enclose the tobacco up to this time. The manufacture of the double cigarettes according to the present invention is a "serial process", in which the double-length tobacco rods (16A) and double filters (18A) lying between the latter are connected to sections of tip paper (20), which are moving axially in order to form a continuous strand, which is then cut through in the centre of the double filter, as a result of which the said double cigarettes (24a) are produced. <IMAGE>

Abstract: In a display device for a tachometer, two circular optical waveguides (4, 5) are arranged coaxially with respect to one another and in each case covering one another. The optical waveguide (4) is conducted with a continuation (10) into an illumination chamber (11) and the optical waveguide (5) is conducted with a continuation (13) into an illumination chamber (12). Each optical waveguide (4, 5) is provided with a scale. When the illumination chamber (11) is switched on, light flows through the optical waveguide (4) and the scale on it becomes visible. When the illumination chamber (12) is switched on, light flows through the optical waveguide (5) so that the scale on it becomes visible. An optical waveguide disc (16) which projects with in each case one continuation (17, 18) into each of the illumination chambers (11, 12) is used for pointer illumination. <IMAGE>
