Patent DE-3132354-A1 (DE)
Title: Blank for an arch support
Inventor: REINHARDT KURT
IPC: A43B7/22
Filed: 1981-08-17
Abstract: For a given size of a foot, the shape of the blanks for an arch support is adapted essentially completely to different foot shapes in that each of these foot shapes is assigned a completely pre-formed blank. Due to this considerable shaping of the blanks they can be largely pre-formed within a specific height graduation relative to the inner and outer lateral parts for the different foot heights. The height of the blank thus no longer needs to be adjusted manually by an expert.

Title: Process and apparatus for the uniform crosslinking on all sides of material in strand form, for example the insulation of electric cables or conductors, by means of directed high-energy radiation
Inventor: DITSCHEID HANS LEO DIPL ING
IPC: B29C48/09
Filed: 1981-10-20
Abstract: The invention relates to a process suitable for the use of directed radiation and an apparatus for the guidance and deflection of material in strand form, for example the insulation of electric cables or conductors, for crosslinking the same. It achieves the object of ensuring a uniform crosslinking on all sides of the product in strand form in a simple way while avoiding the disadvantages of known radiation crosslinking processes. For this purpose, the deflection of the material in strand form takes place in a number of planes, the perpendiculars of which form an angle of 90 DEG  with the central direction of radiation, but form angles other than 90 DEG with one another. <IMAGE>
Patent DE-3143740-A1 (DE)
Title: Electrical comparator
Inventor: POPP WERNER
IPC: H03K3/037
Filed: 1981-11-04
Abstract: In an electrical comparator, one input (1) of the comparator is connected via a first resistor (3) to the one input of a differential amplifier (4), and the other input (2) of the comparator is connected via a second resistor (2) to the other input of the differential amplifier (4). If the variable input voltage (Ux) exceeds the adjustable threshold voltage (Uw) of the comparator, an auxiliary current (IH), which flows through one (3) of the two resistors, creates a voltage drop which is additively superimposed on the variable input voltage (Ux). Due to this measure, the switch-off voltage of the comparator is lower than its switch-on voltage, the voltage drop across the resistor (3) being equal to the hysteresis of the comparator. The auxiliary circuit contains, apart from the resistor (3) already mentioned, a further resistor (8), a constant voltage generator (7) and a switch (6) controlled by the output of the differential amplifier (4). The magnitude of the hysteresis can be set in a simple manner by appropriately dimensioning the auxiliary circuit. <IMAGE>

Title: Tension relief for a cable which is to be held inside a test plug
Inventor: SCHOLTHOLT HANS
IPC: H01R13/58
Filed: 1981-11-27
Abstract: The tension relief for a cable (7) which is to be held inside a test plug (1) and contains a multiplicity of individual conductors (9) which are to be connected to plug tongues (2) arranged in the test plug, is intended to be constructed such that, even if the plug (1) is pulled out by means of the cable (7), detachment of the cable (7) from the plug (1), and undesired separation of individual conductors which are attached to the plug tongues (2), e.g. by soldering, are reliably prevented. This is achieved in that a holder (6) for retaining the cable (7) and a web (13) adjacent to this holder (6) are arranged in the handle part (3) which is to hold the plug tongues (2), and in that a space is provided between the holder (6) and the web (13), which is dimensioned such that an end region (10) (of wedge-shaped construction) of a clamp (8) comes into contact with these parts (6, 13) of the test plug. <IMAGE>
Patent DE-3149880-A1 (DE)
Title: Wet multi-plate clutch
Inventor: FUJIOKA KAZUYOSHI
IPC: F16D13/52
Filed: 1981-12-16
Abstract: In a wet multi-plate clutch for automatic transmissions, the driving and driven plates rotate in a clutch hub in the form of a hollow cylinder. This clutch hub is produced by press-forming and has at least one cut-out, with which inward-pointing projections on the driving plates interact in such a way that the driving plates rotate together with the clutch hub. The clutch hub furthermore has an inward-pointing shielding element which is installed in the inner circumference of the clutch hub in order to guide lubricating oil to the friction faces of the driving and driven plates via the cut-outs, the oil thereby being prevented from splashing uselessly. The shielding element can, for example, take the form of a snap ring which is inserted into an annular groove on the inner circumference of the clutch hub or the form of a cylindrical component with an inward-pointing flange which is inserted into the clutch hub.

Patent DE-3203669-A1 (DE)
Title: Zero-point tracer
Inventor: SCHMIDT WERNER
IPC: G01B3/00
Filed: 1982-02-04
Abstract: The known zero-point tracers are of exceptionally robust and rigid construction as precision instruments. This is necessary so that forces can be absorbed without deforming the zero-point tracer if the same is pressed too forcibly against the workpiece. Nevertheless, it has been found that tracers of this type are maladjusted through faulty manipulations even after a short period of use. In order to remedy this, it is proposed according to the invention that the tracer be of two-piece design and that it be assembled from a holding piece (1) with a tracing piece (5) pivotably inserted therein. <IMAGE>

Patent DE-3217977-A1 (DE)
Title: Device for camouflaging objects against reconnaissance by thermal imagers
Inventor: LOESCHNER WILFRIED ING GRAD
IPC: F41H3/00
Filed: 1982-05-13
Abstract: In order to camouflage against thermal imagers, the object to be camouflaged is covered by a geometrical structure of heat-sensitive sensors and thermal energy sources in such a way that each heat-sensitive sensor is assigned a thermal energy source at the same height and width on the opposite side of the object. The heat-sensitive sensors partially scan the object background and activate via a control unit the thermal energy sources on the side of the object facing the thermal imager, specifically in such a way that this side of the object has the same temperature distribution as the particular object background. The result of this is that the object can no longer be perceived by a thermal imager independently of time and place. The device is also suitable for camouflaging purposes if the thermal energy sources are driven by the control units in such a way that they represent the contours of an object which is no longer present in reality.

Patent DE-3244372-A1 (DE)
Title: Process for producing filled tubular packages, especially of sausages
Inventor: ANDRAE KLAUS DR
IPC: B65B9/213
Filed: 1982-12-01
Abstract: In the process for producing filled tubular packages a film web is bent around its longitudinal axis and formed into a tube. The two longitudinally axially extending edge regions of the web are joined overlapping using a smoke-permeable, adhesive layer containing a pressure-sensitive adhesive, the adhesive layer if necessary being anchored on the web material by an adhesion-permitting resin. The flowable compound is simultaneously forced into the formed tube. In order to join the edge regions of the web, the prefabricated adhesive layer, which is disposed on a backing tape with anti-adhesive surfaces, is transferred with the backing tape to at least one of the overlapping surfaces in the edge region of the web and the backing tape is pulled off the transferred adhesive layer.
Patent DE-3246122-A1 (DE)
Title: Magnetic transmission
Inventor: SCHIWECK HEINZ
IPC: H02K49/10
Filed: 1982-12-13
Abstract: In the single-stage version (Fig. 1), the magnetic transmission consists of a stationary magnetic disc (1) and a magnetic disc (2) which is arranged centrally and axially such that it can rotate. A semicircular segmented disc (3) rotates between the magnetic discs. The power flux from the driving shaft to the driven shaft passes via the magnetic radial forces, which are not interrupted by the segmented disc, of the mutually opposite magnetic discs. The transmission has absolutely no slip and is determined by the pitch of the magnets, or by the number of magnets on the circumference of the magnetic discs. The torques on the two shafts are related in inverse proportion to the transmission ratio. The driving and driven shafts may run in the same direction or in the opposite direction. Rotation in the same direction or in the opposite direction is also determined by specific different magnet pitches on the magnetic discs. The magnetic transmission permits a high transmission level and can also be designed in a multi-stage manner, in an integrated construction. Despite the fixed transmission ratios of the magnetic transmissions the individual magnetic discs can be twisted with respect to one another in stages corresponding to their magnet pitches, for the purpose of setting. <IMAGE>

Title: Control device for machine tools with a spindle
Inventor: BERGMANN LUTZ DIPL ING
IPC: G05B19/23
Filed: 1983-02-25
Abstract: This control device for machine tools serves to position a working spindle (1) at a specific angular position and to transport a tool carriage, which is driven via a threaded spindle (1), into a predeterminable target position by means of an angular position controller or a location controller. The spindle (1) is driven by a motor (3) via a gearbox (2). In order to allow for the mass inertia moments of the rotating parts during control optimisation, the gear transmission ratio (n/f) is formed, its root is extracted via a square-root law transfer element (11) and fed to a multiplier (12) serving as angular controller or location controller. The motor speed actual value (nact) and the spindle speed (f) are used to form the gear transmission ratio (n/f). The spindle speed is acquired from the signal transmitter pulses (P) of a pulse generator (5), on the spindle axis, which serves as an incremental position detection device for the angular position or the carriage position. <IMAGE>
