Title: Tactile imaging device for blind - has image scanned by TV camera supplying signal to tactile field
Inventor: SCHIEF ALFRED DIPL PHYS DR ING
IPC: G09B21/00
Filed: 1975-08-30
Abstract: The tactile imaging device is used to convert an optical image (1) into a tactile image, which can be sensed by a blind person. The optical image (1) is scanned by a T. V. camera (2), which supplies an output video signal to a tactile field. The latter is formed by a table (3) whose surface has a number of movable pegs, the position of each peg corresponding to the video signal from the camera for the same coordinate position of the scanned image. The electrical amplification factor can be adjusted to allow details of the optical image to be ascertained, by measuring the coordinater of the tactile image field via a measuring device (5) or adjusting a lens of the camera (2).

Title: Sliding hatch covers for ship - with pivotted rail wedges to stack covers over each other
Inventor: FISCHER HANS-JUERGEN B ING GRA
IPC: B63B19/18
Filed: 1975-09-19
Abstract: The hatches are closed with two or more covers which run on guide rails along the hatch sills, and which are coupled together by detachable couplings. The ends of the guide rails have pivotted wedges whose ends can be swung upwards at different angles with a simple ram.

Title: Dynamic overload indicator for electronic circuits - has identical network to protected circuit connected to comparator as monitor
Inventor: ROETTER JUERGEN DIPL ING
IPC: G01R19/165
Filed: 1975-12-17
Abstract: The dynamic overload monitor for electronic circuits is suitable for the investigation of amplitude, slew rate and frequency parameters, particularly in measuring equipment circuits. A network having identical parameters to the circuit being protected, e.g. an operational amplifier, has a gain of 1 within the band-width of the monitored circuit. The input signal (Ue) is connected to the simulated network on the one hand and to the protected circuit and one input of a comparator, on the other hand. The output of the network is connected to the second input of the comparator. The comparator gives an output signal only if its inputs vary i.e. an overload is present. In that case, the comparator output signal triggers a transistor switch which energises a l.e.d. indicator.

Title: High current transformer and inductor winding - has coil heights and turns increasing from ends to centre
Inventor: FERGESTAD PETTER INGE
IPC: H01F27/34
Filed: 1976-03-08
Abstract: The high current transformer and inductor winding consists of a number of coils connected electrically in series and along the same a axis. The number of turns in the coils varies from coil to coil and increases in passing from either end towards the centre of each coil. When used as an over-voltage choke, the extreme ends are connected to a common earth or neutral point and the largest centre coil is tapped to give the second connection point. The advantage of arranging the coils in this way lies in giving a linear distribution to the energy carried by a voltage surge.

Title: Tablets contg. discrete granules esp. of pectin - are bonded together by fillers contg. vitamins and trace elements and give exact dosage
IPC: A61K9/20
Filed: 1976-05-08
Abstract: A new galenical formulation consists of tablets contg. granules. These granules pref. consist mainly of pectin or a mixt. of pectin and high-purity clay. The granules may be bonded together by conventional fillers in which vitamins and trace elements are incorporated. Individual granules can be coated with a filler, or a number of granules can be compressed with binder to form a tablet in which the granules retain their structural integrity. When taken orally, the binder is rapidly dispersed while the individual granules retain their form. Fillers are conventional e.g. sugar, CaCo3 etc. and make up 1-80 wt. % of the formulation. The compsns. are made by mixing the granules with a binder (having simultaneously wetting and mildly adhesive props.) then compressing, e.g. in a tablet press, at 6-15, pref. 8-12 tonnes, according to the strength of the granules. Used for usual dietic and pharmaceutical purposes and are rapidly dispersed.

Title: Rolling electrode electrostatic device - having a plate electrode and a coiled electrode separated by insulating plastics sheet
IPC: G02F1/03
Filed: 1976-05-26
Abstract: A rolling electrode electrostatic device comprises a rigid plate electrode, a coiled electrode secured to one edge of the plate electrode, an insulating plastics sheet interposed between the two, and an electric driving arrangement connected between the electrodes when a potential is applied between the electrodes the coiled electrode uncoils into contact with the plate electrode. The insulating layer is pref. of polyethylene terephthalate, 0.0001-0.0005 inch. thick. The use of a hinged electrode is avoided. The device has many applications e.g. as a light stop or as a voltmeter since the length of coiled electrode which uncoils is proportional to the applied voltage.

Title: Forming opening tab in sheet metal container end closures - using bulge whose height is reduced and reformed into opening tab
Inventor: RADTKE CHARLES S
IPC: B21D51/38
Filed: 1977-02-18
Abstract: A bulge, formed in and cut from an end closure central panel, is reformed into an opening tab by reducing the bulge height and its sidewall angle to extend its brim horizontally outward under the rim of the opening from which the bulge is cut, and the brim is coined to further extend it under the rim. Alternatively, an outwardly extending shoulder can be formed in the bulge sidewall, and ironed out to cooperate with the reduction in bulge height in extending the bulge brim outward under the rim. During reforming and coining, the bulge/opening tab is held in a horizontally fixed position relative to the rim to provide a uniform brim-to-rim underlap.

Title: Dietetic bread produced from chinese oats - by three-step yeast addition process
Inventor: JACOB FRITZ
IPC: A21D13/04
Filed: 1977-02-19
Abstract: Dietetic bread is made from chinese oats by introducing the yeast or leaven in at least three stages. In the first stage, approx. equal proportions of natural yeast, ground yeast, ground oats and water are used as the starting mixt. to which, after a first refining stage, a proportion of one-tenth ground oats and one-tenth water are added and stirred in; after a second refining period twice the length of the first, further ground oats of approx. the same weight as in the first and second stages are added together with about twice the quantity of water as in the second stage; in the third stage a creamy dough is thus produced. After a comparatively short maturing time, the final pastry or dough as prepd. by further addn. of ground oats, a proportion of grist and/or flour of a highly sticky cereal of some other type equal to one-fifth to one-quarter of the total amount of oats. Spices and/or salt are also added and the dough is baked in heat-retaining moulds for one to one and a half hrs. at a temp. decreasing from 280 to 200 degrees C.

Title: Carbonisation or gasification of oxidised coal dust - using product gas to preheat the coal for oxidn.
Inventor: SCHUSTER ERNST DIPL ING DR ING
IPC: C10L9/06
Filed: 1977-04-09
Abstract: In the rapid carbonisation and/or gasification (partial or total gasification) of pulverised coking coal, in which the coal is subjected to rapid preoxidation to reduce its caking power, the preoxidation is effected during pneumatic transport of the coal, and the coal is heated to the preoxidation temp. (e.g. 400 degrees C) by direct heat exchange. The process is characterised by the fact that all or part of the gas produced in the process after sepn. of coke dust, is contacted in one or more stages with the coal to be heated, and that at most the 0.005 mm fraction of the coal particles (ranging in size from 0 to 0.2, pref. 0 to 0.1 mm) is heated briefly (for 0.1 sec.) to a temp. in the plastic range of the coal (e.g. 480-500 degrees C). The process utilises the sensible heat of the gas to preheat the coal without significant caking (the 0.005 mm fraction has the lowest content of caking components).
