Patent DE-2932257-A1 (DE)
Title: Document scanner for photocopier - has selector for moving scan for multiple copies and moving document feed for single copies
Inventor: FRANKE WALTER DIPL PHYS DR
IPC: G03B27/52
Filed: 1979-08-09
Abstract: The document scanner for a photocopier has a selector for single or multi-scan. The document is held steady for multi-scan and passes through the scanner for single scan. The scan rate is linked to the process drum and the equipment operates automatically. For single scan, the documents are taken from a magazine feed and passed automatically through the scan position. The scanner remains rigid while the documents are fed over it. For multi-scan, the documents are held over the scan position and the scanner moves over the length of the document. The scan rate is directly linked to the copy feed.

Title: Night storage heater element mounting - has one arm of element secured in flange and other movable axially
Inventor: NUETZEL JUERGEN
IPC: F24H9/18
Filed: 1979-08-04
Abstract: The mounting secures the U-shaped electrical heater element of a night-storage heater in a flange with two holes and near the terminals, the element extending horizontally inside a recess in the heater core. It is only in one of the holes (15,16) of the flange (14) that an arm (2) of the element (1) is secured. The other arm (3) is movable axially in the second hole of the flange. The design avoids the element knocking against the heater core under the effect of vibration, with consequent noise generation.

Title: Powder press with vibrator - has second vibrator causing direct vibration in end face of second tool
Inventor: KROMP WOLFGANG DR
IPC: B30B11/02
Filed: 1980-01-18
Abstract: The powder press uses static pressure on which oscillations are superimposed, having two press tools acting against the material, one of which is coupled to a vibrator. The opposite press tool faces are caused to vibrate in anti-phase, thus generating a potential antinode. A second vibrator is connected to the second tool, causing direct vibration in it end face. The distance between the coupling face in a node of each vibrator (34, 36) and the centre of the chamber (10) accommodating the material can be an odd-number multiple of a quarter-wavelength of the oscillations.

Title: Selector linkage for vehicle gear box - has connecting rod between gear change lever and selector rod
Inventor: GEIGER FRANZ
IPC: F16H59/04
Filed: 1980-05-24
Abstract: The linkage is for a multiple-H-changing of gears.

The shaft is held via a selection lever, and a support rod hinged to it, and the lever is hinged to a gear lever fastened to the shaft. The gear change movement is transmitted via a connecting rod (4), which is hinged to the gear selector rod (1), and to the gear lever (10) of the shaft (9). The hinge point of the connecting rod on the gear lever is at a smaller distance to the shaft axis, than the hinge point of the selection lever (2).

Title: IC engine fuel system - uses capillary nozzle with heater to evaporate fuel of low quality
Inventor: BAENTSCH ERICH
IPC: F02B1/02
Filed: 1980-06-02
Abstract: The method of saving fuel is used with IC engines. It involves using less refined fuel in conjunction with a capillary evaporator nozzle. The fuel is heated in the nozzle under pressure and vaporises explosively at the exit from the nozzle when the pressure is released. Ignition is provided electrically, optionally assisted by an ignition channel. The capillary evaporator nozzle is similar to the devices developed previously in the early days of IC engines.

Title: Transversal and rotary tool positioner - has three point controller with integrating servo, whose characteristics are additionally modulated
Inventor: WERMUTH GISBERT DR ING
IPC: G05D3/18
Filed: 1980-06-04
Abstract: The positioner of the tool assembly comprises a three-point controller with an integrating servo-element. The characteristics of the three-point controller are modulated by an additional system in such manner that the change-over magnitude, generated by this system, is incorporated at a suitable point into the control circuit. Pref., the modulating change-over magnitude is superimposed onto the control magnitude of the control circuit. Alternately, the modulating magnitude is superimposed on the guide magnitude of the control circuit. This modulating magnitude may be superimposed to that characteristic of the three-point controller which determines the width of the neutral zone. In front of the position control circuit may be connected a further control circuit, consisting of a summation point, an integrator and a linear feedback.

Title: Gravity flow separator to clean peas for canning etc. - makes good peas bounce over obstacles which trap waste and reject peas
Inventor: SCHMIED JANOS
IPC: A23N12/02
Filed: 1980-07-14
Abstract: Machine comprises one, or several superimposed, gravity flow cleaning unit(s). A mixt. of peas and waste is fed down an inlet throat to fall on to a rebound plate set at a predetermined angle to the horizontal. Each good pea bounces off the rebound plate to follow a trajectory which carries it over a dropout gap followed by a vertically adjustable barrier. The pea drops into an exit for good peas or on to a chute leading to the exit. Waste material and reject peas do not generally bounce high enough to clear the dropout gap and those that do are directed back by the barrier. The width of the feed throat is pref. adjusted so that the layer of mixt. directed on to the rebound plate has a thickness of approx. one pea. The cleaner is pref. multi-stage with reject material from stage one entering the inlet throat of stage two and so on. Cleaning peas ready for processing for canning, freezing etc. The cleaner has to remove pieces of pod, leaves, stalk, weeds, stones, soil, insects, moth grubs etc. also deformed and poor quality peas.

Title: Filter mat for use in water engineering
Inventor: UNGER JOACHIM
IPC: E02B3/12
Filed: 1981-02-18
Abstract: Such a filter mat has a fibre layer (5) composed of unneedled, coarse man-made and/or non-rotting natural fibres or fibre wastes, and this layer (5) is joined on one side of the mat to a filter-active layer (4), preferably comprising a woven fabric, an unneedled spunbonded or unneedled nonwoven, by stitch-bonding (3). The stitch-bonding (3) comprises threads of a heat-shrinkable material, preferably metallic threads or synthetic monofilaments, which form a three-dimensional structure by interlooping through the mat and which form constrictions and depressions when the thread material shrinks, with zigzag-shaped (toothed) constrictions (1) being formed on the upper surface of the mat and straight-line ridges (2) which extend transversely to the longitudinal direction of the mat being formed on the lower surface of the mat. The stitch-bonding (3) produces on the one hand a reliable and permanent join between the two layers (4, 5) and on the other an improved anti-slip effect. <IMAGE>
