Patent DE-3233759-A1 (DE)
Title: Device for the step-by-step forward movement of a shaft in the axial direction
Inventor: KAJINO YUKIMASA
IPC: H02K7/065
Filed: 1982-09-11
Abstract: In a device for the step-by-step forward movement of a shaft in the axial direction, a cylindrical piston is provided initially which surrounds the shaft and is held such that it can move in a reciprocating manner in the axial direction between a front and a rear limit position, with the aid of a suitable drive. During its forward movement, the piston is coupled to the shaft in the front limit position. However, this coupling is released when the piston is moved to the rear limit position. In consequence, the piston takes the shaft with it during its forward movement but the piston leaves the shaft in the pushed forward position during its return movement. The reciprocating movements of the piston in this way ensure a step-by-step forward movement of the shaft.

Title: Copying-protected prerecorded video cassette and method and coder for producing and method and decoder for playing such a video cassette
Inventor: HIRSCH PETER
IPC: H04N5/913
Filed: 1982-09-24
Abstract: On the magnetic tape of a video cassette, the video signals are stored distorted or modified for copying protection. Furthermore, a coding associated with the video cassette is provided on the magnetic tape. When the video cassette is played, the correspondence of the coding existing on the magnetic tape with a coding which is applied to a code carrier belonging to the video cassette is compared. On agreement, a circuit arrangement is activated by means of which the distortion or modification of the video signals is cancelled.

Title: Process for producing wood pulp having improved strength properties
Inventor: BORSDORF GUENTHER DIPL ING
IPC: D21B1/14
Filed: 1983-07-01
Abstract: The invention relates to a process for producing wood pulp having improved strength properties for the manufacture of paper and cardboard. The process according to the invention pursues the aim of making possible, by means of a higher temperature in the wood before and in the action zone, easier defibration and gentle removal of the fibres from the wood, without many short broken fibres being formed. According to the invention, this is to be achieved in such a way that this wood already has, in a substantial part thereof, a temperature of more than 40 DEG C even before the action zone in which the wood is then heated by the defibration process.

Abstract: In a valve for pressure containers, for example single-way compressed-gas cylinders, which consists of a valve housing (2) which is placed on the container, of a valve body (1) which can be moved therein by means of a handle, and of an outlet for the extraction o the fluid container contents, a valve element (5) is provided in order to prevent refilling of the container once it has been completely emptied, which valve element (5) can be moved from a fixed open position by means of an aid which acts from the outside, for example a mandrel or the like which can be moved irreversibly into a position in which it remains in the open position subject to the container pressure, while it is moved out of this position into a locking position in the event of an overpressure acting from the outside and/or under the influence of an auxiliary force, for example a spring force. In one preferred configuration, the valve element (5) is constructed in the manner of a ball non-return valve, whose ball is fixed in the open position, by means of a blocking element (6), before the action of the aid, for example a mandrel, and is released after filling, possibly with partial destruction of the blocking element (6), so that it rests in a sealing manner on the valve seat (5) in the event of an external overpressure. <IMAGE>

Title: Drive device for a beam system on a weaving machine
Inventor: NORLIN GOERAN
IPC: D03D49/10
Filed: 1983-11-15
Abstract: The invention relates to a drive device for the beam system of a weaving machine. The beams of the system are driven synchronously by a drive motor at both ends via two step-up gears coupled to one another by means of a transmission shaft. The drive motor is a stepping motor which is driven by pulse compositions. The length of the switching steps of the motor can be controlled by variations of the pulse compositions. There is provided a pulse-generating device, by means of which it is possible to generate for each work cycle of the weaving machine a pulse composition which is variable in dependence on one or more settings of one or more actuating members. The respective setting of the length of the switching step of the drive motor and therefore of the beams corresponds to the density of the fabric produced on the weaving machine.

Title: Rig for a windsurfing board
Inventor: WAGNER GERT
IPC: B63B35/79
Filed: 1983-12-02
Abstract: The invention relates to a rig for a windsurfing board, with a mast (1) and a sail (13) held by the mast and held stretched by means of a wishbone (4), the sail (13) being provided with a mast pocket (9) which accommodates the mast, and additional spreader battens (12) being provided for stabilising the profile. The wishbone (4) is fastened to the mast (1) via a lever arm (5) extending in the bow direction of the sailboard. Furthermore, the wishbone (4) is pivotably mounted on the lever arm (5) via an essentially perpendicular axis (6). The mast pocket (9) is preferably designed to be substantially wider than corresponds to the diameter of the mast. On account of the prevailing force relationships, this construction ensures that, depending on the direction of travel, an optimum leading angle of the profile with simultaneous, likewise optimum, asymmetric deformation of the profile occurs. <IMAGE>

Patent DE-3413143-A1 (DE)
Title: FM modulator
Inventor: WUERL WERNER ING GRAD
IPC: H03K7/06
Filed: 1984-04-07
Abstract: An FM modulator, particularly for modulating video signals, is described which allows simple linearisation of the characteristic and simple calibration. This is achieved by the fact that the threshold voltage of one of the controlled elements of the modulator is changed as a function of the modulator input signal in such a manner that the difference between the threshold voltages of the controlled elements decreases for higher FM frequencies. Such an FM modulator has a simple structure, allows simple linearisation of the characteristic and simple calibration and, in addition, is particularly suitable for optical waveguide systems.

Title: Electrical underground locomotive and driver's cab
Inventor: BRUETSCH WALTER
IPC: B61C17/04
Filed: 1984-05-02
Abstract: The electrical underground locomotive (1) has two driver's cabs (7) and a main body (2) which contains the drive motors (3) and traction control equipment (14). The driver's cab (7) is constructed as an interchangeable component and is detachably connected (10) to the main body (2). Each driver's cab (7) has an entry and exit opening (11, 12) on each side. A number of the control and supply lines of the driver's cab are connected to the corresponding lines of the main body (2) via plug-in or press-in contacts (15). In this underground locomotive, the cab is open for entry and exiting on both sides. This prevents critical situations, for example when the exit is blocked on one side during underground operations or on tipping ramps. <IMAGE>

IPC: B23K15/04
Filed: 1984-10-13
Abstract: A branch construction for an enamelled reaction vessel is described, wherein the lower annular rim on the outer surface of a cylindrical branch neck is arranged, corresponding to the width of an annular inner surface of the bore, in the bottom or in the cylindrical wall of a vessel adjacent thereto and is welded thereto by electron beam welding. The underside of the branch neck pointing to the interior of the vessel has a curvature designed to be capable of being enamelled. Preferably, the branch neck is welded along a horizontal or vertical annular surface to a flange ring, likewise by electron beam welding. The use of electron beam welding and numerically controlled machines makes particularly economical manufacture possible.

Title: Shot-triggering device for firearms
Inventor: HOFFMANN KARL
IPC: F41A19/58
Filed: 1984-10-17
Abstract: In the case of firearms having a single-stage hair trigger, the handling safety is increased by the use of an electrical or electronic protection trigger having a hysteresis characteristic, in that the weapon does not intrinsically revert to being ready for firing once a shot has been triggered but is made ready for firing by the gunner immediately before triggering the protection. Restraining forces can thus not lead to inadvertent triggering of a shot. A spring, which additionally acts in the shot-triggering direction, engages on the trigger element. <IMAGE>
