Inventor: OSWALD JOSEF
IPC: B29B17/02
Filed: 1982-03-24
Abstract: The invention is concerned with processes and apparatuses for comminuting used tyres and for recovering the component parts of rubber, cord and steel. Without first of all having to remove the bead rings, the tyres or tyre pieces (24) are subjected to continuous comminution between fixed stator cutters (7) and rotating cutting tools (6) as well as fixed flexing bars (9) and rotating flexing tools (8) along an enforced movement along the axis of a tool roller (2), which rotates in a fixed hollow-cylindrical housing (1). The rotating tools (6, 8) are arranged along one or more helices on the tool roller (2). As a result, the steel parts (25) are exposed. At the end of the housing (1), the tyre pieces (24) are comminuted to such an extent that they can be delivered through a screen (4) and then separated in the usual way. <IMAGE>

Title: Arrangement for representing curves on the screen of a display device
Inventor: KRETZSCHMAR BERND
IPC: G09G1/16
Filed: 1982-07-14
Abstract: To brighten the area between curves which are represented on the screen of a display device and for interpolating the curves, a logic circuit (VKN1) is provided which logically combines the curve point signals read out of a frame buffer (BSP) with signals coming from a hold circuit (REG2, REG3, SP1, SP2, REG4, REG1), in such a manner that when a curve point signal occurs first time in a row or a column, the curve point signal is entered into the hold circuit in which it remains stored until a curve point signal occurs for the second time in the same row or column. To brighten the area between the curves, the signals stored in the hold circuit are supplied to an unblanking control (HTS). For interpolating, the hold circuit is followed by a row or picture element delay circuit (REG2, REG3, SP1, SP2, REG4, REG5 and REG5), depending on whether the abscissa extends along the row direction or perpendicular thereto, the input and output signals of which delay circuit are supplied to a comparator (EXO1). If they are not equal, the unblanking control (HTS) receives an unblanking signal. The field of application of the invention are display devices. <IMAGE>

Title: Method and device for adjusting the draft ratio of a drawing unit of a spinning machine
Inventor: NAKAYAMA TERUO
IPC: D01H5/32
Filed: 1982-10-22
Abstract: The invention relates to a method and a device for adjusting the draft ratio of a drawing unit of a spinning machine. In the method according to the invention, a cross-sectional measurement value of a fibre strand to be spun is determined and is corrected by means of the weight numbering of the fibre strand. To determine the cross-sectional measurement value, in the apparatus according to the invention the fibre strand inserted between two side plates is exposed to different pressure loads and its respective height is determined. The cross-sectional measurement value is obtained from the measurements extrapolated to zero load. By means of data predetermined for the relevant type of fibre as regards the thread properties which are achieved during the spinning of the type of fibre, with the main draft ratio kept constant and with various values of the product of the weight-corrected cross-sectional value and of the preliminary draft ratio, the value of the preliminary draft ratio and therefore of the overall draft ratio can be set for the same constant main draft ratio after selection of the desired thread properties on the basis of the weight-corrected cross-sectional value of the fibre strand to be spun.

Title: Sheet-type roller blind for the air-conditioning of buildings
Inventor: SCHMID JUERGEN DR ING
IPC: E06B9/24
Filed: 1982-12-24
Abstract: The invention relates to a sheet-type roller blind for the air-conditioning of buildings. Roller blinds of this type are known as a means which protects against cold or heat and is located between windows. By convective heat transfer or heat conduction, the known sheets are not capable of preventing room-heat radiation through the window. It is thus proposed to provide a thermal insulation zone between the roller-blind sheet and the window pane and to apply the reflection layer for the room radiation on that side of the sheet which is directed towards the window glass.
Patent DE-3301537-A1 (DE)
Title: Air-cushion surfer
Inventor: RICHTER GUENTHER DIPL ING
IPC: B63B35/79
Filed: 1983-01-19
Abstract: By using support wings and correspondingly shaping the body, the speed or air flow achieved by the propulsion of a windsurfing rig can be used to generate an air cushion in a manner derived from windsurfing. This air cushion produced in between the surface of the water and support wings serves essentially to reduce drag. This reduction in drag permits a substantial increase in the speed. If the angle of attack of the support wings is increased with the aid of the sail by means of corresponding action of the driver, such large lift forces are produced on the support wings that a climbing flight can take place.
Patent DE-3304958-A1 (DE)
Title: Apparatus for dissolving fibrous materials in liquid
Inventor: KOHL ERICH DIPL ING
IPC: D21B1/34
Filed: 1983-02-12
Abstract: The invention relates to an apparatus for dissolving fibrous materials, such as reject paper or paper waste, in liquids, in which apparatus the liquid and the fibrous material are stirred by a driven rotor in a vessel. In known devices there is insufficient mixing, and it is thus possible to reduce considerably both the time and the energy requirement of the dissolution process. This is achieved according to the invention by providing the inner face of the main part in the circumferential direction, with at least one inwardly directed profile whose line, with the largest radial distance from the main part, starts roughly horizontally in the lower region of the main part, and via an upward arc, after a section in the circumferential direction of the main part, turns into a vertical tangent and from there, in a continuation of the arc, is returned for a short distance up to approximately the upper end of the main part.

Title: System for the transdermal administration of substances with pharmacotherapeutic activity
Inventor: SCHNEIDER KLAUS DR
IPC: A61K9/70
Filed: 1983-05-28
Abstract: The invention relates to a system for the transdermal administration of active substances, which consists of a microporous film which has been produced from a thermoplastic polymer and has a pore structure in which essentially spherical cells with an average diameter C of 0.5 to 100  mu m are connected by pores with an average diameter P which is less than the diameter of the cells. The cavity volumes formed from the contributions of the cells and pores is 10 to 90% by volume. The film has a smooth surface with a degree of openness of 10 to 90% and contains a solution or dispersion of a pharmacotherapeutic agent. This system is particularly suitable for administering nitroglycerine. No control membrane is necessary for metered delivery of the active substance onto the skin. Since both the cell or pore size and the total cavity volume contribution can be varied, a large number of therapeutic programmes is possible with the system. It is possible to employ virtually all active substances which can be used transdermally in veterinary and human medicine.

Patent DE-3403346-A1 (DE)
Title: Motorised hang glider which is capable of a running start
Inventor: BLEIDIESEL WILFRIED
IPC: B64C31/028
Filed: 1984-02-01
Abstract: A weight-controlled hang glider which is capable of a running start and has a pushed propeller engine suspended on a load rod which can pivot is described, in which the tail load distribution is compensated for by using the weight of the pusher propeller engine to shift the pilot's weight forwards to a corresponding extent in front of the centre of gravity. This can be achieved, on the one hand, by means of two parallel "hip rods" which extend from the pusher engine to the pilot's hips. However, this can also be done by means of two cables which are mounted in the small of the pilot's back, one of which runs at the rear end of the load rod, and the other of which runs to the front end of the load rod, which is pulled forward to a large extent. In addition, this system simultaneously and automatically results in the weight displacement control movements of the pilot being converted into inclinations of the propeller plane or of the propeller air jet, as a result of which a "power-steering" effect is produced, which increases the flight safety and comfort in powered flight.

Title: Bell valve for the pressure-resistant shutting off of highly abrasive media
Inventor: LANGER RUDOLF
IPC: B65D90/62
Filed: 1984-02-24
Abstract: The invention relates to a bell valve (1, 32) for the pressure-resistant shutting off of highly abrasive media. In the case of such bell valves, the valve seat, but in particular the O-ring, is subjected to considerable wear by the grainy constituents of the medium. In this respect, the invention provides a protective sleeve (13, 25), which bears against the element carrying the medium and is pressed by an adjusting force against the valve plate (4, 21) or, when the valve plate is lifted off the valve seat (9), against a stop (15, 26). Furthermore, when bearing against the stop, the protective sleeve may be pushed forward with its rim which faces the valve plate almost into the plane of the O-ring (11, 23). A bell valve according to the invention is suitable in particular for use for the pressure-resistant shutting off of abrasive media. <IMAGE>
