Patent DE-3130221-A1 (DE)
Title: Deep-hole boring attachment for boring predrilled workpieces
Inventor: WASCHKE PAUL-GERHARD DIPL ING
IPC: B23B29/02
Filed: 1981-07-31
Abstract: The invention relates to a deep-hole boring attachment for boring predrilled workpieces, in particular applicable to lathes, horizontal boring machines and special deep-hole boring machines. The aim of the invention is to increase the quality and effectiveness during the boring of deep bores. The object is to develop an attachment with which bores which run virtually true can be obtained at a high cutting speed in combination with a high surface quality. This object is achieved in that a guide rod is releasably connected to a boring head, and the guide rod is guided in a guide bush of a counter-bearing. <IMAGE>
Patent DE-3134400-A1 (DE)
Inventor: GERCKEN KARL
IPC: B60J3/02
Filed: 1981-08-31
Abstract: The sun screen for motor vehicles or the like, made as a padded element, comprises a padding material covered by a thin envelope and fixing means arranged at its edge and allowing for its pivoting mounting in the vehicle. Said fixing means comprise a hinge located at one end and a trunnion, approximately parallel to the edge and ratchable in a bearing fixed to the vehicle, located at the vicinity of the other end. The problem existing with sun screens of this type, consists in mounting the trunnion so that the covering of the padding material with the envelope is not hindered by the presence of said trunnion. Such problem is solved by inserting the straight trunnion (10), through openings provided in the envelope, in mortises carried by the branches of a stirrup (12) mounted in the body of the sun screen, after the padding material has been covered. The trunnion is locked, in a mortise, against rotation and, in the other mortise, against axial displacement.

Title: Device for the manual propulsion of small floating bodies
Inventor: BLUEGGEL ERWIN
IPC: B63H16/18
Filed: 1981-10-21
Abstract: A device for the manual propulsion of small floating bodies intended for passenger transport and having propulsion means detachably arranged on the floating body is to be designed in such a way that, in a simple manipulating arrangement, the propulsion means only take up a small space and thus do not endanger swimmers. For this purpose, the propulsion means are arranged on the free ends of double-armed levers which are mounted in supports in such a way as to be pivotable inside one plane, which supports are held laterally on the floating body by detachable straps embracing the floating body. The propulsion means are here designed in such a way that they offer different flow resistances in the water in opposed pivoting directions. Here, the propulsion means can be formed by two symmetric blades which are adjacent to one another, are pivotable to a limited extent relative to one another and are held by hinges or film hinges. <IMAGE>

IPC: B22D18/04
Filed: 1982-04-22
Abstract: A description is given of a method for casting molten metals, in particular magnesium, with a low-pressure casting device (1). The low-pressure casting device (1) has a casting mould (2), a heatable crucible (3) for holding a metal melt (4) to be cast, a metering vessel (7) arranged in the crucible (3), a riser (11), starting from the metering vessel (7), preferably extending vertically upwards, and having a mouthpiece for connection to a gate (12) of the casting mould (2); a heating jacket (13) surrounding the riser (11) and a pressure line (14) connected to the metering vessel (7). To pump the molten metal into the casting mould (2), a pressurised gas is introduced into the metering vessel (7) via the pressure line (14). According to the invention, relatively great compaction of the metal and largely void-free castings of high mechanical strength are obtained by the fact that the molten metal is pumped at a delivery pressure of 0.5 to 6.0 bar, preferably 0.6 to 2.0 bar, in particular 0.6 to 1.2 bar. <IMAGE>

Patent DE-3237378-A1 (DE)
Title: Rotary sleeve combustion engine
Inventor: VIETH WERNER
IPC: F01B13/06
Filed: 1982-10-08
Abstract: When the rotary sleeve combustion engine is started, the rotary sleeve is set in rotating motion. The pistons inserted in the rotary sleeve are controlled by a disc cam. The disc cam has an elliptical shape. On reaching the upper curve one of the pistons runs in a downwards moving direction and draws the fuel-air mixture through the intake duct which is located in the upright outer sleeve. As the rotary sleeve continues to turn, the piston is forced again in an upwards moving direction and the fuel-air mixture is compressed and ignited at the top firing point. The combustion pressure produced presses on the vertical edges formed in the combustion chamber and forces the rotary sleeve into a rotating circular motion. The pistons following at equal intervals repeat the same process.

Title: Drive arrangement for a line drum
Inventor: POLLMANN JUERGEN
IPC: B65H75/34
Filed: 1983-03-22
Abstract: A line drum, which holds a supply line for supplying a mobile load from a fixed-position connecting point, is intended to be driven such that the supply line is held continuously under tension between the line drum (10) and the load. For this purpose, a sensor (34) is arranged on the load, which sensor supplies a signal which is proportional to the speed of the movement of the load. The drive motor is a short-circuit-rotor motor which is supplied from a frequency converter (22) with a frequency which is dependent on the signal from the sensor (34). The frequency also depends on the signal of a signal transmitter (38) which supplies a signal which is dependent on the winding diameter. This signal is used to correct the desired value for the frequency converter. <IMAGE>
