Patent DE-3243253-A1 (DE)
Title: Apparatus for portable circular saws, for use as a tilting and mitre saw
Inventor: WOEBKE KLAUS
IPC: B23D45/02
Filed: 1982-11-23
Abstract: To extend the possible uses of portable circular saws, the portable circular saw is inserted, by way of its guide block or base plate, into the guide rails of a frame adjustable in width. As a result of the guide rails, the portable circular saw is provided with exact guidance for horizontal saw cuts of from 0 to 180 DEG . The adjustable frame is movably connected to the mounting plate by means of a joint or a hinge, so that the frame, with the inserted portable circular saw, can be tilted upwards or from the top downwards. With the aid of the tube (round) fitted in the mounting plate at the appropriate angle, the apparatus is clamped into the holder of a drill stand or corresponding stand. By loosening the holder, the apparatus can then be swivelled by from 0 to 180 DEG . Consequently, it is possible to use a portable circular saw readily as a tilting and mitre saw by means of this apparatus. By pushing the frame down during sawing, the material to be cut is pushed on to the support and thus simultaneously secured, thereby at the same time guaranteeing safe operation.

Title: Method and device for forming joints in masonry of existing buildings
Inventor: HELLMANN OTTO
IPC: E04G23/02
Filed: 1982-12-31
Abstract: For forming joints in masonry of existing buildings while developing as little noise as possible, it is proposed to arrange a plurality of, preferably three, crown hollow drills in one plane and provide supports allowing both movement of said drills in their axial direction corresponding to their drilling direction and in their arrangement plane perpendicularly to the drilling direction, and allowing pivoting in their arrangement plane. By making adjacent holes and then shifting the drills by an amount approximately corresponding to their diameter, a continuous joint can be obtained, the smallest width of which depends upon the drill thickness and drill spacing. <IMAGE>
Patent DE-3249826-A1 (DE)
Title: Optionally forward or laterally swivelled shovel loader shovel
Filed: 1982-01-13
Abstract: The shovel is fitted for optionally swivelling forwards or sideways on a shovel loader. The assembly has an open-fronted trough (2) and carrier (3) detachably linked by top and bottom coupling elements (9,10,17,18) to a carrier frame movable vertically and swivelling forwards. The trough is attached so as to twist sideways. The top and/or bottom coupling elements, effective between carrier and frame, incorporate elements which can be coupled further forward, or further to the rear, in relation to the shovel loader's longitudinal direction. They may be attachable at a number of discreet angles between carrier and frame. This prevents loss of material over the front shovel edge when discharging sideways.

Title: Method for the production of valve sleeves for rotary slide valves
Inventor: ROGERS PETER ROLAND
IPC: B21C37/20
Filed: 1983-09-23
Abstract: The valve sleeve of a rotary slide valve is produced by placing a tube 10 on a cylindrical mandrel 20 which has axially extending projections 23. The tube 10 is then pressed or forged onto the mandrel 20 in a die, longitudinal grooves corresponding to the projections 23 thereby being formed on the inner surface of the tube 10. The tube deformed in this way is then withdrawn from the mandrel 20, pushed onto a smooth mandrel and deformed in a die in such a way that the ends of the grooves are closed. The method can be used to produce valve sleeves with longitudinal grooves closed at the ends and having exactly arranged control edges, from a single piece of metal.

Title: Oxygen steel converter or electro-steel arc furnace with refractory basic lining
Inventor: GROSPITSCH HUBERT DIPL ING
IPC: C21C5/48
Filed: 1983-11-22
Abstract: To avoid accidents and extensive spalling, reducing the durability, of the side-wall inner linings in converters and electric arc furnaces due to deflagrations of explosive gas/air mixtures which form in the lining from the contents of pitch, tar, bitumen or plastic in the refractory lining bricks and the ramming in between and which greatly expand on rapid heating of the furnaces and cannot escape without hazard through the dense fire-side surfaces of the lining bricks from the lining into the furnace interior, the side-wall inner linings are provided with nozzles in the form of corners of the brick surfaces or breaks in the longitudinal edges of the bricks, through which the explosive gases can escape into the furnace interior without hazard. The nozzles in the side-wall inner lining can be of different shapes and can be provided in any desired number and position. Bricks having nozzle-forming shapes can alternate with bricks without nozzle-forming shapes. Inserts which provide advantages for the furnace and slag formation, for an increase in refractoriness and the like, can be inserted into the nozzles.
Patent DE-3346715-A1 (DE)
Title: Improvement of the heat transfer in the stabilization of a textured yarn
Inventor: BAUER KARL DR ING
IPC: D02G1/02
Filed: 1983-12-23
Abstract: The process according to the invention is aimed at improving the heat transfer between the heating device and yarn in the stabilizing zone following the texturing. The improvement is achieved in that, in the heating zone, the yarn is made to vibrate transversely to its running direction or to balloon. Vibration is excited especially by applying a false twist by means of a false-twist device which imparts to the yarn, behind the heating zone and in front of a delivery unit located there, a temporary twist which in turn causes the yarn to balloon. The trigger frequency can be varied by changing the rotational speed of the false-twist device.
Patent DE-3347920-A1 (DE)
Title: Saw apparatus
Inventor: BERGLER OTTO
IPC: B23D47/02
Filed: 1983-08-16
Abstract: A saw apparatus is described which consists of a saw unit with a saw housing and a motor-driven saw blade which is held on a longitudinal guide running parallel to the plane of the saw blade. The longitudinal guide is arranged in the edge area of a rotatable round table which in turn is let into a work rest which on one side of the round table, where the latter has a plunging slot continuous up to the periphery, has a recess, corresponding to the mitre-cut range, for the saw blade. The round table is provided with an extension arm which has a plunging slot in alignment with the plunging slot of the round table. This configuration results in the advantage that a smaller round table and thus also a smaller unit overall can be provided, although a large cutting range is to be covered.
Patent DE-3403395-A1 (DE)
Inventor: BLOECHER EBERHARD DIPL ING
IPC: F02D41/14
Filed: 1984-02-01
Abstract: The invention is directed to an apparatus for metering an air-fuel mixture to an internal combustion engine. The apparatus includes a characteristic field set up with operating quantities of the internal combustion engine for anticipatorily controlling engine variables that influence the air-fuel mixture and a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic field values. The characteristic field values are stored in the characteristic field and selected in dependence on operating quantities of the internal combustion engine. The characteristic field values are modified by means of different control methods to correctively influence the same. More specifically, the control methods include a control to a minimal specific fuel consumption in the lower and part-load ranges as well as a control to maximum power in the upper load range as may be necessary. This control arrangement can be realized, on the one hand, with an extreme-value control which is superposed either on the air or quantity of fuel delivered to the motor or, on the other hand, with a direct control of the air ratio  lambda  with an exhaust gas probe, for example. With the apparatus of the invention, a minimal specific fuel consumption with reduced exhaust gas emissions are realized while at the same time ensuring a satisfying driving behavior of the vehicle.
Patent DE-3413578-A1 (DE)
Inventor: KOCH WERNER LUTZ
IPC: A61C8/00
Filed: 1984-04-11
Abstract: An enossal implant for securing a tight-fitting tooth replacement having two parts which are to be connected with one another. One part, having a bore hole, is placed in the jawbone. The other part, comprising a peg which serves to hold the replacement tooth, is replaceably inserted in the hole. The diameter of the cylindrical external wall of the peg is dimensioned larger than the diameter of the bore hole so that the peg, at body temperature, is compressed within the bore hole, but at reduced temperature can be removed from the bore hole due to reduction in the external dimensions of the peg. Such a connection is simple to handle, cannot loosen, and is practically free of cavities so that no bacterial colonies can form in the implant.
