Patent DE-2945483-A1 (DE)
Inventor: WIENER DIETER DR ING
IPC: B23F17/00
Filed: 1979-11-10
Abstract: In order to improve and obtain greater variability in the crowning of the tooth flanks (3, 4), such a device for grinding by the forming or generating method with indexing control, having a cup wheel which can be driven in rotary manner about a grinding axis (5), is developed in such a way that an additional movement of the grinding axis (5) on an elliptical motion path (6) is performed. This enables the curvature of the tooth flanks (3, 4) to be varied within a wide range without the tooth thickness being affected. A design refinement of the realisation of the additional movement is proposed in which a link of predetermined length is mounted at one end in such a way that it can be pivoted and driven in a rotary manner about a link axis fixed to the device; a pivoted arm of predetermined pivoting length is mounted at the other end of the link in such a way that it can likewise be pivoted and driven in a rotary manner about a pivot axis; and the grinding axis is guided by the free end of the pivoted arm; and furthermore the angular velocity of the pivoted arm is opposed to the link and is twice as great as the angular velocity of the link relative to the device. <IMAGE>

Abstract: The ionisation chamber, is used to ionise the particles in a gas flow so as to improve their separation in separators downstream. The electrode system used is resistant to erosion and can operate at temps. up to 450 degrees C. The cross-sectional area of the separators does not differ from that of the gas channel. The ionisation chamber is earthed and has conducting sidewalls. The spray electrodes (11) are made from round wires greater than 1.5 mm dia. raised to a high potential to produce a corona discharge. The electrodes divide the housing into two sections along the direction of flow (12) of the gas. Each section is at a different polarity. The chamber is sealed by a cover (6) with insulators (7) projecting into the chamber. The spacing between the electrodes is less than 250mm.

Title: Protection circuit power stages of electrified railway - has voltage limiter shunting inductor of LC input filter
Inventor: MANCHEN JOACHIM DIPL ING
IPC: H02H7/122
Filed: 1980-01-25
Abstract: The protection circuit, for use in power stages whose supply volts are apt to return suddenly, e.g. current collector jumping an electric locomotive, gap in power rail, has a voltage limiter (5), e.g. a Zener diode, in parallel with a capacitor (7). The capacitor is shunted by a resistor (8) and is in series with a diode (6) across the inductor (2) of the input filter. The avalanche voltage of the Zener diode is slightly greater than the admissible voltage fluctuation at the buffer capacitor (3) and is designed to handle the energy stored in the inductor in the worst case. The voltage limiter may also be a voltage-dependent resistor.

Title: Electropneumatic strewing plant for motor vehicles - with injector downstream of vane compressor
Inventor: ZIMMER HORST
IPC: B60B39/08
Filed: 1980-02-12
Abstract: Electropneumatic plant to provide an individual supply of sand, mixed with salts, for the wheels of individual motor vehicles and trailers in winter to improve the adhesion on icy roads, includes an airtight container for the granules and hoses leading in front of each wheel.

Title: Fabric from thread impregnated with epoxy! resin - as sieve or support material for wet filtration
Inventor: KLINKENBERG TILLMANN DR
IPC: D03D15/00
Filed: 1980-03-29
Abstract: A fabric consists of woven threads of synthetic material(s), where the threads and/or fabric have been treated with a compsn. of an unmodified and/or internally plasticised epoxy resin and a hardener acting catalytically on heating. The compsn. penetrates into the core of the threads, and the heat-induced polymerisation of the resin causes the formation of compact threads, giving a definite stiffness to the fabric. The fabric is esp. a sieve or support fabric for wet filtration. Softer, more easily processed threads can be used. The fabric has mechanical strength, and resistance to hydrolysis and chemical action. Filter fabrics repel both soil and filter-cake.

Title: Pig stunning machine - with electrodes on guide element above V=shaped conveyor pair
Inventor: KAUFMANN SIEGFRIED
IPC: A22B3/06
Filed: 1980-07-31
Abstract: A machine to stun pigs in abattoirs consists of two endless belt conveyors which convey the animal in their V-shaped gap underneath a guide rail. A guide element carrying two electrode beams is moved along by the animal against the adjustable resistance of a cylinder so that the electrodes are pressed against the sides of the pig's head. A switch applies the current and a set of power cylinders returns the guide element with the electrodes to the initial position. This eliminates the heavy manual labour required for hand-held stunning tongs and cuts out imperfect stunning operations.

Title: Telecommunications miniature cable connector - has paired junctions along jack strip with backplate inlaid crossover and separate connections to sprung conductor links
Inventor: THOM GUENTER
IPC: H04Q1/14
Filed: 1980-08-28
Abstract: Increased capacity in miniaturised construction of cable connectors is achieved by layering the connections, between conductor termination and plug jack, in the top and bottom of the rigid connector back moulding. The internal connections (3,4) are inlaid into the rear rigid connector moulded backplate (1) with one connector (3) appearing directly on the outside of the jack strip end and the second (4) making a crossover to appear on the inside of the jack strip end. Both connections associated with each cable pair are then correspondingly placed along the length of the jade strip for connection with the female (6) connector (12). The crossover (between 3,4) has an angular deviation to maintain insulation parameters. The cable termination (15,16) of the connectors (3,4) uses a spring and wire holder mechanism (15,16,10,21,14) pressure element to ensure insulation free conducting grip on the cable conductors.

Title: Multi-lingual alphanumeric display with accent marks - has auxiliary electrodes above and below character to add accents found in various languages
Inventor: YAMAMOTO MASAMITSU
IPC: G09F9/302

Abstract: An alphanumeric character display, e.g. liquid crystal, has 14 electrode segments (a...n), or a 5x7 dot matrix (1b), to form all the numerals 0 to 9 and letters A to Z. Auxiliary electrodes above (2a,b) and below (4a,b) the display enable accents or special characters to be formed, e.g. for multilingual word processors. For German, two dots (3) above are used for umlaut and a downward bar (5) to the left below forms the 'sz' character (5,e,f,a,k,g,l,d). Further auxiliary electrodes are added for other lanquages. Two sloping bars above, like a drooping moustache, can form French acute or grave accent and circumflex, and a hook below forms cedilla. A third bar sloping up to the right of the circumflex forms the sinuous sign above N in Spanish. A small circle above can be used with A in Swedish.

Title: Quick closure valve esp. for nuclear reactor coolant system - has closure plate displaceable towards support grating if flow reverses
Inventor: KUMPF HERMANN DIPL ING
IPC: G21C9/00
Filed: 1980-10-03
Abstract: Quick-closure shut-off valve for the flow cross section esp. of a duct connection to a nuclear pressure vessel is to close if a duct bursts or similar major accident in the primary circuit occurs. A heavy grating across the section of the duct offers low flow resistance to the circulating water and acts as a valve seating on the pressure vessel side to a movable valve plate. The device can be used either on an inlet flow connection or on an outlet flow connection. When a flow reversal occurs the valve plate rapidly closes onto the grating. For an inlet connection the valve plate is held in the open position by the normal flow pressure, whereas for an outlet connection, it is held in the open position by rupture elements which fracture under a predetermined load. Periodic testing of the device is possible.
