Title: Front and rear marked package prodn. - using two foil tracks carrying same markings but having different measurements, optically checked, welded and later separated
Inventor: SIEBEN LOTHAR
IPC: B65B41/18
Filed: 1980-07-16
Abstract: The prodn. method is for packages with non-overlapping markings on the front and back sides made from two foil tracks carrying the same marking but vary in measurement. The markings of both foil tracks are optically measured and in accordance with the determined difference in measurement the foil track with the shorter measurement is lengthened rhythmically up to the longer measurement of the second foil. The markings of both foils are then guided one above the other, sealed or welded together and subsequently separated into separate packs.

Title: Data system with high transmission rate - has added broad band channel switched by standard processor
Inventor: STAUDINGER WILHELM DIPL ING
IPC: H04L12/52
Filed: 1980-07-26
Abstract: A normal electronic data system (EDS) operating, for e.g at a rate of 2400 bits per second has at least some of the connections (y1,y2) augmented by extra connections (x1,x2) associated with a high speed transmission system. The control information is transmitted at the low or normal bit rate and is used to order the switching (K) of the high bit rate connection (x1,x2). The message is sent at the high rate, for e.g 64000 bits per second. This high speed circuit is wholly decoupled from the normal processor and is thus free from any disturbance which might be caused by the latter having to operate at a higher than standard rate.

Patent DE-3037901-A1 (DE)
Title: A.M. transmitter system - uses peak clipper and low pass filter to prevent modulator from being over-driven
Inventor: KROLL DIETMAR DIPL ING
IPC: H03C1/62
Filed: 1980-10-03
Abstract: The transmitter is arranged so that the amplitude of a carrier wave is modulated and controlled with a carrier value that is a function of the level of the modulation signal. This level is determined by packing off at a point in the modulation signal path. The control circuit for the value of the carrier can follow an upward jump in the level in less than 20ms. The rate of change of the controlled carrier value is limited to keep boundary transmissions within limits. The modulator is prevented from being overdriven by a peak clipper followed by a low pass filter. This prevents boundary transmissions. The limitation of the peak value of the modulation signal depends on the level of the unlimited modulation signal with a different time constant based on the rate of change of the value of the carrier.

Title: Presettable counter with mechanical drive - has damage prevention with combination adjustment wheels acted upon by external latches
Inventor: ZEPF HUBERT
IPC: G06M1/28
Filed: 1980-12-17
Abstract: The presettable counter is esp. with a signal device and mechanical drive with negative decade transfer and locking setting wheels and uses a composite numeral wheel. This enables an externally accessible coupling to be used which ensures that when opposite setting and drive directions are used incorrect operation cannot lead to damage to the counter mechanism. The two adjustment wheel halves for preselection are mutually adjustable in the additive sense and are connected via a coupling disc (33). A sprung coupling lever (20) acts externally upon the coupling disc (33) so that the latching gears (35) on both sides engage the inner latching gears (32) of both adjuster wheel halves. Preselection is by setting keys (21) which secure blocking elements (37,38) in the output position and release them when pressed.

Title: Pressure-tight capsule for a valve magnet
Inventor: FAGETH GERHARD
IPC: H01F7/08
Filed: 1981-02-13
Abstract: The invention relates to a pressure-tight capsule for a valve magnet which serves as a guide housing for a moving armature. The capsule consists of a magnetisable core with an opening to allow the passage of a valve-actuating tappet and with a non-magnetic guide tube which is mounted approximately coaxially on a shoulder of the core and the end of which remote from the core is closed in a pressure-tight manner. The guide tube is soldered to the core, the solder flowing into a gap between the inner wall of the guide tube and the circumferential surface of the shoulder from a starting point. According to the invention, the circumferential surface (11) of the shoulder (3) is unprofiled and the radial depth of the step (10) to the core (2), measured from the circumferential surface (11) of the shoulder (3), corresponds approximately to the wall thickness of the guide tube (4). The starting point (15) for the solder is in the corner region (16) between the end face (12) of the shoulder (3) and the inner wall (17) of the guide tube (4), from where the solder flows into the gap between the guide tube and the core. Such a design of the pressure-tight capsule allows higher static and dynamic pressures and, in particular, the capsule according to the invention withstands several million stress reversals without becoming leaky. <IMAGE>

Title: Valve magnet for direct current
Inventor: FAGETH GERHARD
IPC: F16K31/06
Filed: 1981-02-17
Abstract: In order to form a closed magnetic circuit, the excitation coil of a direct-current valve magnet is sheathed in a metallic casing whose ends are formed by pole plates which are held in a positively-locking manner. The casing is rolled from a sheet-metal part, a longitudinal slot generally remaining at the point of the seam. In the event of temperature fluctuations, the casing is spread apart, as a result of which the air gap to the pole plates is enlarged and the magnetic reluctance of the circuit increased, and the tensile force of the valve magnet is thus reduced. According to the invention, the abutting edges (4, 5) of the casing (1, 1') engage in one another in a positively-locking manner at the seam point, so that, in the event of temperature fluctuations, expansions of the casing can largely no longer occur. The casing itself absorbs the temperature stresses which occur. In order to achieve a positive lock, which is largely free of any air gap, between the casing (1, 1') and the pole plate (20, 20'), the pole plate is provided with an attachment (21), which is integrally formed by stamping, is positively locking radially and preferably engages in the casing (1, 1') with a push fit. <IMAGE>

Title: Process for preparing sulphur as granules
Inventor: ANGELE BERNHARD DR
IPC: C01B17/02
Filed: 1981-06-19
Abstract: The invention describes a process for preparing sulphur as granules and an appliance for carrying out the process by means of which it is possible, in an economical and simple manner, to obtain, as a dry end product, granular sulphur which has a high fracture strength (crushing strength), in conjunction with considerably reduced formation of dust during the preparation process, as well as a uniform particle size range. This is made possible by the sulphur first being brought to a temperature above 158 DEG C, which imparts to it a viscosity which makes it possible to convert the sulphur into a droplet form which does not quickly run on a cooled surface. It is possible, by cooling down on a cooled surface - a belt cooler in at least two stages - to avoid, given a suitable choice of the cooling temperature, excessively rapid cooling and thus supercooling and liquid discharge of the sulphur. There is provided, as an appliance for carrying out the process, a rotor droplet former which does not require a major constructional effort and permits granulation of the sulphur according to the process according to the invention in a simple manner.

Title: Electronically controlled circular cross-cut saw for wood
Inventor: HOFMANN WOLFGANG
IPC: B23Q7/06
Filed: 1981-11-05
Abstract: In an electronically controlled circular cross-cut saw, the wood to be cut to length is gripped at its rear end by a carrier fastened to a pulling means and is pushed to the circular cross-cut saw. A roller having an electronic rotary transducer is attached to the pulling means in such a way that said rotary transducer serves as a rotary- and hence position-measuring device for a speed control system, the deflection of the chain, seen in the conveying direction, taking place after the saw blade, and the pulling means being attached so far under a feed channel, in which the material to be cut to length is guided, that a free cutting of the circular saw blade is possible without touching the pulling means. To achieve a high degree of positioning accuracy, the speed changes and the braking can be electrically controlled and the frictional forces between wood and feed channel can be changed.

Title: Process for machining the exposed surfaces of concrete slabs as well as device for carrying out this process
Inventor: SAMEITH HORST
IPC: B28D1/18
Filed: 1982-05-27
Abstract: For machining the exposed surfaces of concrete slabs, a process is proposed in which the slabs, lying on their exposed surface, are fed to the stock-removing tool and the stock-removal is carried out from below. Furthermore, a device for carrying out the process is described. It is advantageous that, even with different slab thicknesses, a uniform stock removal on the exposed side takes place, so that separate calibration devices are superfluous, without the stock-removal being too intense in individual regions in the case of non-uniform slab thickness.
