Title: Axial piston engine with variable stroke
Inventor: DROESCHEL HELMUT
IPC: F04B1/29
Filed: 1984-06-01
Abstract: Especially as spark ignition engine, the stroke of which varies in operation in a ratio of up to 3:1 with approximately constant compression and good mass balancing in order to save fuel and transmission gears. (Can also be designed as compressor or hydraulic pump and/or air motor or hydraulic motor.) The swashplate 49 in the drive of the axial pistons 67 arranged in a circle is supported on the one hand on a rotating, inclined crankshaft 34, which is axially fixed. On the other it is cardan mounted on an axially displaceable fork 55. The axial stroke of the pistons 67 can thereby be adjusted for an approximately constant compression  epsilon . For external mass balancing, a balancing weight 25 in the rotating crank 23 is moved on an inclined path in the event of axial movement of the fork 55, so that not only the imbalance (of the swashplate 49) is thereby balanced out but also together with this the tilting moment of the swashplate 49 B.b and of the pistons 67 A.a also rotating as a rotating pair of forces C.c. This balancing weight 25 acts in conjunction with two symmetrical centrifugal weights 31 also for balancing of the internal inertia forces. For design reasons, it is therefore mounted on the side opposite its actual effect. It therefore produces the balance necessary for the mass balancing in conjunction with a greater constant imbalance Q of the crank 23 on the right side. Due to the inertia forces F and G of the pistons 67 and the swashplate 49 ... <IMAGE>   Original abstract incomplete.

Patent DE-3430072-A1 (DE)
Title: Coin acceptance and coin rejection device
Inventor: DREYER ULRICH DIPL ING
IPC: G07F9/04
Filed: 1984-08-16
Abstract: For the coin acceptance and coin rejection device of an automatic vending machine, in which the inserted coins, after running through a test device, are first stored in an intermediate money box before they are fed to a collecting box after the initiated dispensing of a product or, if the customer decides accordingly, to coin rejection, without the dispensing of a product, by the actuation of a return button, the intermediate box is designed to be pendulously pivotable, the coins sliding out of the intermediate box during the pivoting of the latter. For pivoting the intermediate box, there is provided a slide which can be actuated by the return button and which can be guided in two directions. In one direction of displacement, the slide causes the pivoting of the intermediate box and therefore the coin rejection, and in the other direction of displacement the slide slides ineffectively past the intermediate box, without bringing about a coin rejection. The two directions of displacement are controlled via a control element which can preferably be actuated electromagnetically. An electrical interlock with the product-dispensing devices is provided at the same time, so that no coin rejection is possible when the dispensing of a product is initiated.

Title: Rig for a sailing craft
Inventor: NOWAK PETER
IPC: B63H9/06
Filed: 1984-09-07
Abstract: The invention relates to a rig for a sailing craft, with a mast and a sail area producing the propulsion. To increase the propulsion, the sail area is provided with an asymmetric profile and can be tilted and pivoted via the masthead joint. The necessary constructional stability at low weight is obtained by a top and bottom tower part to which stays are attached. In light and favourable winds, auxiliary sails can be run at the end points of the rig. Capsizing in the case of watercraft is prevented by the installation of floating bodies in the hollow space of the profile, and righting is facilitated by means of the tilting rig. For transport or in the event of a storm, the rig can be folded up in a simple manner to form an elongated pack. Higher speeds with simple handling and a high degree of safety are possible with the novel rig. <IMAGE>

Title: Device for compacting granular moulding materials
Inventor: TANNER HANS
IPC: B22C15/272
Filed: 1984-11-29
Abstract: Device for compacting granular moulding materials, in particular foundry moulding materials, with a pressure vessel for storing a highly pressurised gaseous medium, which vessel is connected to a moulding device via a valve. The opening of the valve or of the valve seat is formed by a plurality of directional through-openings, which are covered or exposed by a lift-type valve plate. The gaseous medium can flow freely around the circumference of the valve plate. The valve plate is likewise provided with through-openings, but these are arranged offset relative to the through-openings in the valve seat. To trigger the pressure shock for compaction, the shock being determined from the gaseous medium, the lifting device for the valve, which operates with a tipping effect, is actuated and the valve plate is raised suddenly, as a result of which the gaseous medium, both flowing around and flowing through the valve plate, exerts a pressure shock on the surface of the moulding material. Such a pressure shock reaches an intensity which is capable of compacting moulding compositions in an effective manner, even where the mould areas are large. <IMAGE>

Title: Process for manufacturing strip-shaped silicon crystals with a horizontal pulling direction
Inventor: RAUSCHER GERHARD
IPC: C30B15/00
Filed: 1985-07-12
Abstract: In a process for horizontal silicon ribbon pulling, in which the supporting body at the same time is the crystallisation nucleus for the build-up of the crystalline silicon strip, that end of the melt (4) which, in the pulling direction (6) is situated near the melting trough rim (5), is exposed to the action of a travelling magnetic field (1, 2, 3), so that as a result of the interaction between induced currents and travelling field a pressure acting in a non-contact manner is exerted on the melt meniscus (8) counter to the pulling direction (6) and thus stabilises the meniscus. This avoids the melt (4) being pulled along across the trough rim (5) by the crystallising layer (7). The process is used in the manufacture of silicon crystals for solar cells. <IMAGE>

Title: Rotary engine
Inventor: BUHMANN FRIEDRICH
IPC: F01C1/344
Filed: 1985-08-16
Abstract: The rotary engine is a very significant improvement in terms of the efficiency of all engines than has hitherto been possible with reciprocating engines, because the rotary engine comprises essentially fewer components, has less energy/heat loss and functions without uneconomic mass acceleration of reciprocating pistons. It is an entirely new, completely centrically rotating rotary piston machine for all engines for liquid and gaseous fuels, which can achieve a very high exploitation of the primary energy used and helps to reduce the pollutant emissions in internal combustion engines by virtue of unleaded petrol or other fuels and also by improved combustion. It largely replaces many engines with reciprocating pistons.

IPC: D05B57/26
Filed: 1985-10-09
Abstract: The invention relates to a thread-loop control arrangement of a sewing machine having a horizontal gripper, which has the aim of providing an arrangement with a thread-loop control element, in order, in conjunction with thread regulation, to increase further the reliability of the seam-forming process. Moreover, the solution is to be capable of being put into practice and produced economically by few technical means. By means of a thread-loop control element, the thread-loop regulation is carried out in such a way that the regulating effect occurs as early as directly behind the holding finger of the oscillating carrier in the thread draw-off region of the horizontal gripper. According to the invention, the guide face of the guide track in the fourth quadrant of the horizontal gripper forms, on the bobbin carrier, two faces which are connected in a step-like manner. The thread-loop control element is arranged parallel to these faces and with a clearance for air round the thread and is provided in a step-like manner with a guide face. The guide face is formed on the thread-loop control element at a distance from the guide face corresponding to the width for the holding finger and extends in the direction of the oscillating movement of the holding finger. <IMAGE>
