Title: Noise screen wall slats - comprise two flat arms at acute angle, with one protruding downwards
Inventor: ROSTAN WALTER DIPL ING
IPC: E01F8/00
Filed: 1979-09-12
Abstract: Lamellae incorporating sound-absorbing material are mounted parallel to each other on fixed posts or frames, to make up a wall affording protection from noise. They consist of two virtually flat-shanks enclosing an angle (alpha), of approx. 45 deg. One shank (2) is sited in a vertical plane perpendicular to the noise source or direction of noise dissemination, while the other (1) is cantilevered in this direction, to terminate in a plane (16) perpendicular to the foot (13) of the first. They pref. form a monolithic laminated unit. Sound waves strike against the lamellae surfaces, and are more fully absorbed. The exposed parts can be hard, smooth and durable, the vulnerable sound absorbent material being protected by the overhang.

Title: Multi-cavity injection mould has valved sprue ducts - enabling each cavity to be separately cut off from main sprue
Inventor: POSCH GERHARD ING GRAD
IPC: B29C45/27
Filed: 1980-08-09
Abstract: Mould comprises a number of mould cavities, each fed by a sprue duct from a central sprue in the mould. The sprue ducts lie in the parting plane of the mould. Each sprue duct has an individual cut-off valve, enabling it to be closed when desired. The rotatable component of this valve, having the form of a valve plug or cock, can be reached from the parting plane when the mould is opened and possesses an actuating device enabling it to be closed or opened in this condition of the mould. The arrangement enables any faulty cavity to be completely cut off by closure of the associated valve. In this way a complete cut-off is obtained, better than that previously possible by inserting a plug into the relevant sprue duct.

Title: Measurement of AC voltages on protective switches - capacitively stores one half-wave whilst other is being measured
Inventor: KRAUSE HORST ING GRAD
IPC: H01H9/54
Filed: 1980-08-14
Abstract: The circuit for measuring alternating voltages on protective switches contains a storage circuit which suppresses the voltage spikes occurring when the switch turns off. It can reproduce the actual value of the switching spike voltage without a delay and very accurately. Two capacitors (3,4) acting as the storage elements are connected alternately to the a.c. voltage being measured via one changeover switch (1) and to a voltage measurement circuit (11) via another changeover switch (2). This ensures that during each half-wave period the a.c. voltage is connected to one capacitor whilst the other capacitor voltage is being measured. The changeover switches are controlled by a null voltage switch (8) producing pulses whose durations corresp. to the voltage half-wave periods. They may consist of LMOS semiconductor switches.

Title: Linearising circuit for approximately linear temp. sensors - has ROM producing additive correction signal
Inventor: SCHOEPFLIN KARL-HEINZ DIPL ING
IPC: G01D3/02
Filed: 1980-08-16
Abstract: A linearising circuit for measurement sensors whose characteristics deviate slightly from a straight line, e.g. a thermoelement, resistance thermometer etc., is suitable for a strip recorder. It has very good long-term stability, small error tolerances and an economical design. The input signal is linearly amplified in an amplifier circuit (4,R1,R2) and added to a correction signal derived from a further amplifier circuit (R4,R5,R7,9) and a digital signal processing circuit (5,7,8). The processing circuit contains a digitising a-d converter (6), a r.p.m. (7) programmed to produce the appropriate correction, and a d-a converter (8). The quantisation jumps of the correction signal are interpolated by superimposing on the a-d converter input the output of a low amplitude h.f. triangular wave generator (10). The linearised output is filtered in a summing low pass filter (R3,R6,5,R8,C).

Title: Adjustable cutter for underground coal mining machines
Inventor: GARTE RUDOLF
IPC: E21C27/32
Filed: 1981-02-05
Abstract: Underground, coal mining is carried out with shearers as well as with ploughs with the use of various carbide-tipped cutters mounted in pockets. Cutters with a cutting edge or even with a cutting pick are used in various embodiments for shearers. A cutter consumption of 500 cutters/face per month is nothing unusual. The cutters for plough operations have one cutting edge, as well as three cutting edges which are fitted in pockets specifically provided for this purpose. For the requisite rate of cut, a certain cutter is specifically required for this purpose. A large number of cutters must be kept in stock, since different cutters are used for the ploughing and the cutting. The invention shows a cutter with four cutting edges which reduces not only the procurement costs but also the operating costs. The cutters are used for ploughing as well as for cutting and are also used as radial and even as tangential cutters with an adjustable rate of cut. <IMAGE>

Title: Pressing device for treating a pasty solids suspension
Inventor: KOCH KLAUS DIPL PHYS
IPC: B30B9/12
Filed: 1981-10-10
Abstract: A pretreatment station for a pressing device is disclosed for a pasty solids suspension such as, for example, sewage sludge, paper pulps or other liquid/solids mixtures. The pretreatment station should operate continuously, have a high take-up capacity, be operable at low energy costs and be simple and robust with respect to construction and the mode of operation. This object is achieved by the provision of at least two exchangeable perforated sheet containers on a rotary take-up disc, underneath which a stationary disc with an eccentric opening is arranged coaxially, whose cross-sectional area corresponds to the size of the cross-sectional area of a perforated sheet container and to the cross-sectional area of a filling port of the pressing device. By timed rotation of the rotary take-up disc, one container is in each case moved underneath a filling branch, filled and rotated further. The contents of the container are predehydrated by settling of the solids components and draining of the liquid from the holes of the container, for example by 5-10 %, and finally transferred into the filling port of the actual pressing device. Since the perforated sheet containers are open at the bottom and slide on a stationary disc, the bottom sealing of the containers is very important. The invention describes several illustrative examples of such seals.
