Title: Rotary piston machines
IPC: F02B53/00
Filed: 1963-10-10
Abstract: 1,017,568. Rotary-piston engines. NSU MOTORENWERKE A.G. and WANKEL G.m.b.H. Oct. 10, 1963 [Oct. 13, 1962], No. 39975/63. Heading F1F. In a rotary-piston I.C. engine of the trochoidal n and n+1 lobe type annular members 14, 15 are attached to end faces of an eccentric 7 on which the piston 8 is rotatably mounted, and metallic sealing-rings 16 are lodged between said members and the end walls of the piston to prevent lubricant entering the working chambers. A rubber ring 17<SP>1</SP> is provided in each sealing ring to effect sealing between the ring and an adjacent flange 19 on the periphery of the associated annular member, the ring being biased in the direction of the piston by a leafspring 17. Each of the annular members has a central tubular hub 22, or 23, in engagement with an aperture in the adjacent side wall 3, or 4, of the engine housing, spiral grooves 23 being formed in said hubs to seal a clearance gap 24. Cooling of the piston is accomplished by circulation of lubricant through passages 30, 31 in the annular members and a cavity 13 in the piston, the lubricant also serving to lubricate gearing 10, 11 for controlling the planetary motion of the pistons, a bearing 9 supporting the piston on the eccentric, and bearings for a power-output shaft 6. Each of the rings 16 may be replaced by a ring 16<SP>1</SP> (Fig. 3, not shown) which is pressed by springs against a ring 25 attached to the piston and having a flange 25 mating with a groove in the associated annular member. An outwardly-inclined gap 27 between each annular member and the corresponding ring 25 serves to return lubricant by centrifugal action to cavity 13. Alternatively, sealing between the annular members and the piston is effected by the provision of a narrow gap between each ring 25 and the associated annular member (Fig. 4, not shown), or each ring 25 has axially-extending flanges mating with grooves in the adjacent annular member to form a labyrinth seal (Fig. 5, not shown). The annular members may be integral with the eccentric and one of them may be omitted, in which case sealing of one side of the piston is achieved by application of an axial load to press the piston against the adjacent side wall of the housing.

Abstract: 1,071,728. Shearing. VERWALTUNGSGESELLSCHAFT MOELLER UND NEUMANN OFFENE HANDELSGESELLSCHAFT. Oct. 1, 1965 [Nov. 6, 1964], No. 41716/65. Heading B3W. An apparatus for trimming the ends of, and for removing a sample length from travelling rolled material such as rods or bars comprises two disc cutter shears 1, 2 disposed one behind the other and guide tubes 3, 4 in front of the shears which positively displace the rolled material to effect a cut and is characterized in that the shears can be rotated bodily through 90 degrees so that cuts can be effected by pivotal movement of the guide tubes in both directions. Operation.-In order to crop the leading and trailing ends of a length of material and cut a sample length from each end of the remainder the guide tubes 3 and 4 are moved to the position of Fig. 1a. The leading end of the material passes through the guide tube 3 and operates a photo-electric cell which causes the guide tube 3 to swing to a position in line with the fixed tube 5. The leading end A is thereby cut off and the remainder passes through the tube 5 into the tube 4. When the required sample length has passed the guide tube 4 is swung to a position in line with the guide tube 6, so that the sample length is cut off by the shear 2 and the remainder of the material passes through the tube 6. The pivotal movement of each of the guide tubes 3 and 4 initiates the movement of the shears 1 and 2 from the positions shown in Fig. la to that shown in Fig. 1e. When the trailing end of the rod approaches the guide tubes 3 and 4 are moved simultaneously to the position shown in Fig. 1a so that a sample length which is equal in length to the distance between the shears is cut out and passes down the guide tube 4 and the trailing crop end passes down the guide tube 3. Pivotal movement of the guide tubes again initiates movement of the shears which return to the position shown in Fig. 1a. In an elaboration of the apparatus for cutting an additional sample length from the middle of the length of material the guide tube 3 directs the material into one of two parallel paths, one of which leads to the shear 2 and the other of which leads to a third shear 7, Fig. 2 (not shown). Each of these parallel paths contains two pivoted guide tubes, the first of which, in each ease, directs cut-off material out of the line and the second of which displaces the material through the shear 2 or 7 and either directs it out of the line or into a fixed guide tube.
