Title: Measuring coercive field strengths on extensive surfaces - by quasi-stationary and dynamic cycling through hysteresis curve
Inventor: THEINER WERNER DR RER NAT
IPC: G01R33/14
Filed: 1980-10-08
Abstract: A method of determining the coercive field strength on extensive surfaces with mangetoinductive and magnetoelastic measurement parameters involves quasi-stationary and dynamic cycling through the hysteresis curve. It enables the hitherto necessary special calibration procedures and strong geometric dependency to be eliminated. The method involves use of the fact that the maxima of the reversible permeability over the tangential field strengths coincide with the coercive field strengths. The maxima of the superposition permeability over tangential field strength coincide with the actual coercive field strength values up to a deviation of half the peak-to-peak residual alternating field amplitude. Because the reversible permeability can by definition only be measured in the limiting case where the residual field magnitude tends to zero, the superposition permeability is measured in practice.

Title: Rope assembled from aromatic polyamide fibres - in alternate flocked and non-flocked layers
Inventor: ARTZ HERMANN JOSEF ING GRAD
IPC: D02G3/40
Filed: 1980-10-18
Abstract: A strand, cable, rope or the like composed of synthetic elementary fibres, esp. aromatic polyamide, laid up in a number of layers, comprises layers of these fibres alternately flocked and unflocked in their radial sequence from the inside to the outside. In a variant, strands of a rope are made up in this way and alternate adjacent strands have their outer layers of fibres unflocked and flocked respectively. This arrangement enables high-strength ropes to be produced without exceeding their theoretical final dia. as occurs when all the individual elements are flocked.

Title: Mine support system beam slip arresting clamp - has paired gripping shell pieces, threaded bolts and arresting pieces
Inventor: LUTHER FRIEDRICH
IPC: E21D11/14
Filed: 1980-12-03
Abstract: The clamping system prevents lateral slipping with the support section itself, for beams used in support systems in long faces or galleries in underground mining, in conjunction with shields or hydraulic props. In clamps for this purpose, two gripping shells (a,b) are firmly connectable with the support section (g) in connection with two threaded bolts (e,f) and two arresting pieces (c). The arresting pieces may serve both for screwing to the support section and for accommodating the beam concerned, so as to prevent it from slipping sideways. For fixture, wedges may be used instead of screws.

Title: Caravan superstructure with variable body length
Inventor: LANGHOFF GUENTHER DR
IPC: B60P3/34
Filed: 1981-04-02
Abstract: The subject of the invention is the caravan superstructure (WWA) which can be shortened for driving mode and remains useable. The shortening or lengthening affects the part of the WWA which serves to accommodate the bunks; they are possible on both sides. The bunks can be folded up and anchored in the core cell of the caravan (WWKZ). When folded up they clear the space which they take up which can be saved when travelling. The saving takes place by means of a turning and folding technique for those parts of the outer surfaces of the caravan which enclose the bed space and are releasably held. They are turned or folded inwards and securely fixed to the WWKZ, or received by it, to form a "packet". Shortening or lengthening corresponds to the inner height of the caravan and is approximately 1900 mm on one side. The invention serves to make driving and maintenance simpler and cheaper and can be used for touring caravans, mobile homes and motor homes which are to be made more spacious and have short chassis, it can also be used for portacabins for accommodation purposes of all kinds (emergency accommodation, stock holding), whose bulkiness makes storage and transportation difficult. Here, gains in floor area of up to 45% are possible. <IMAGE>
Patent DE-3114356-A1 (DE)
Inventor: WIGET FRIDOLIN
IPC: G04C3/14
Filed: 1981-04-09
Abstract: An electronic timepiece suitable for use with different types of batteries having different voltages, and including a stepping motor 6, an oscillator 1, a frequency divider 2 and a motor control circuit 5, comprises a battery voltage detector 8 and a pulse shaper circuit 9 capable of producing pulses of different durations. The voltage detector circuit 8 controls the pulse shaper circuit 9 to cause it to supply the motor control circuit with pulses whose duration depends upon the detected battery voltage, whereby the drive pulse power will be substantially the same irrespective of the type and voltage of the battery fitted. In another embodiment trains of short pulses are used instead of single pulses and the duty cycle of the short pulses is varied. <IMAGE>

Title: Winding apparatus and method for strip or wire
Inventor: JOST GERD
IPC: B65H65/00
Filed: 1981-09-24
Abstract: For winding up wire or strip in rolling mills or in the case of metal melts which are sprayed directly onto a cooling drum, it is necessary for the arriving strip to be caught and clamped fast on the circumference of a winding drum until the winding process is running continuously. In the solution to this problem according to the invention, use is made of a hollow winding drum with an opening, which is only set in rotation when the start of the strip passes through the opening into the interior of the winding drum. <IMAGE>

Title: Method for synchronising binary data signals transmitted bidirectionally via a signal line
Inventor: SCHNEIDER ADOLF DIPL ING
IPC: H04M9/00
Filed: 1981-09-30
Abstract: The occurrence of a pulse edge is monitored within a predefined time slot in data blocks with a defined number of outgoing pulses and with return pulses inserted in their time gaps, and a synchronisation signal is derived from its absence; every pulse gap occurring instead of an outgoing pulse resets a counter to a starting position and blocks the processing of the data signals until a further pulse gap occurs following the defined number of outgoing pulses. The method can be used in telephone PABX systems with a central unit and with peripheral terminals connected to this unit. <IMAGE>

In order to ensure rapid and permanent closing, a supporting pipe connecting piece (7, 8), for the pipe section which is constructed as a baffle pipe (3) is inserted into the pipe housing (1) on the gas inlet side and on the gas outlet side respectively. Both supporting pipe connecting pieces (7, 8) are connected in the overlapping region with the baffle pipe (3) via at least one connecting duct (9, 10) to the annular duct (2) between the pipe housing (1) and the baffle pipe (3). The closing body, which is constructed as a closing piston (5) is inserted under the influence of pressure into the baffle pipe (3) between the supporting pipe connecting pieces (7, 8) on the gas inlet side and on the gas outlet side. The supporting pipe connecting piece (8) on the gas outlet side has an inner cone, tapering in the flow direction, as a sealing seat (6) for the closing piston (5), which is arranged upstream in the flow direction. <IMAGE>

Patent DE-3145950-A1 (DE)
Title: Front wheel suspension for motorbikes
Inventor: HUBER SIEGFRIED
IPC: B62K25/08
Filed: 1981-11-20
Abstract: A front wheel suspension for motorbikes is described which prevents the front wheel fork dipping when the front wheel brake is actuated. For this purpose, during the braking process, a control piston closes the choke openings through which the working chambers of the telescopic shock absorber are connected. The control piston is acted upon by an electromagnet which can in turn be excited by the brake light switch. In order to permit deflection of the front wheel fork during the braking process, a through-flow channel which is equipped with a non-return valve is provided in a closure connecting element of the telescopic shock absorber. A further through-flow channel in this closure connecting element permits the shock absorber to absorb hard impacts on the front wheel fork even during the braking process. The closure connecting element itself bears both the inner tube of the telescopic shock absorber and the aforementioned electromagnet.
