Patent number: 9206802Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.Type: GrantFiled: April 24, 2010Date of Patent: December 8, 2015Assignee: SWASHPUMP TECHNOLOGIES LIMITEDInventors: Lindsay Bruce Dalziel, John Layne, Benno Frank Smit

Patent number: 8662870Abstract: A swash pump for compressible fluids uses sealing contacts made between the nutatable swash plate and the fixed cone plates to center and locate the inner swash sphere which slides against two resiliently mounted ring seals only, minimizing pump friction. A slanted end of a common drive shaft supporting and turned by the rotor of an integrated, variable speed motor causes nutation of the sphere. All bearings, especially axially slidable roller bearings inside the sphere, may settle in position with respect to the common shaft for least frictional loss. This pump is also adapted for pumping explosive gases.Type: GrantFiled: September 18, 2009Date of Patent: March 4, 2014Assignee: Swashpump Technologies LimitedInventors: Lindsay Bruce Dalziel, Benno Frank Smit

Patent number: 6409885Abstract: A pulp forming machine includes a forming head including a platen and plurality of mould carriers. The mould carriers are connected to the platen by mould carrier support means which allow the mould carrier and the platen to transmit forces perpendicular to the general plane of the platen but allow movement and expansion of each mould carrier in the general plane of the platen. Mould carrier to mould carrier locating means locate the mould carriers of opposing platens during the forming process to align moulds carried on the mould carriers with cooperating moulds of the cooperating platen.Type: GrantFiled: June 15, 2000Date of Patent: June 25, 2002Assignee: Fisher & Paykel LimitedInventors: Benno Frank Smit, Brent Richard Mooney, Christopher Arthur Good, Andre Brian Aish

Patent number: 5760374Abstract: An apparatus for heating an advancing thermoplastic yarn led over heating ridges along a heated surface. An essential feature of the invention is that the heating ridges can be maintained at a temperature as high as that of the heating surface, in particular at a temperature sufficient for ensuring a self-cleaning effect, without damaging the yarn. If required, the heat flow on the yarn may also be regulated by adjusting the height of the heating ridges and/or by modifying the length of contact with the yarn.Type: GrantFiled: March 9, 1995Date of Patent: June 2, 1998Assignee: Barmag AGInventors: Heinz Schippers, Karl Bauer, Johannes Bruske, Martin Fischer, Benno Frank, Siegfried Morhenne, Ralf Dedeken, Herbert Streppel

Patent number: 5578231Abstract: A heater (1) for an advancing thermoplastic yarn which is guided along a heated surface over ring segments (2). The flow of heat to the yarn is adjustable by changing the geometric parameters of the heat transfer.Type: GrantFiled: April 4, 1994Date of Patent: November 26, 1996Assignee: Barmag AGInventors: Heinz Schippers, Karl Bauer, Johannes Bruske, Martin Fischer, Benno Frank, Siegfried Morhenne, Ralf Dedeken, Herbert Streppel

Patent number: 4402179Abstract: A yarn false twisting apparatus is disclosed which comprises two rotating twist imparting members, with a pressure applying member comprising a cylinder-piston assembly positioned to bias one member toward the other at the twisting zone. The apparatus includes an improved yarn thread-up capability which avoids breakage when the yarn is initially twisted, and which includes a pressurized air supply system for biasing the piston of the pressure applying member into operative contact with the adjacent twist imparting member, and control means for substantially reducing the pressure during yarn thread-up to thereby limit the nipping force applied to the yarn. In one embodiment, the air supply system includes a reservoir for cushioning the application of the pressure on the piston to thereby avoid the rapid application of a nipping force on the newly threaded yarn.Type: GrantFiled: June 12, 1981Date of Patent: September 6, 1983Assignee: Barmag Barmer Maschinenfabrik AGInventors: Peter Dammann, Benno Frank

Patent number: 4236323Abstract: A yarn heating apparatus is provided which is adapted for use in a false twist yarn crimping machine or the like. The heating apparatus comprises an arcuately curved heater plate mounted in a generally vertical orientation within a channel in an insulated housing, and having one or more yarn receiving grooves extending along its length. A flat cover is provided which includes an insert mounted on the inside of the cover, and which is sized to fill substantially the full width of the channel. The cover is hinged to the housing by an arrangement which permits the insertion and withdrawal of the insert along a path of travel which is parallel to the side walls of the channel, to thereby avoid injurious contact between the insert and walls of the channel. The inner face of the insert may be curved in conformance with the curvature of the heater plate, such that when the door is closed, the inner face defines a yarn passage of uniform cross-sectional configuration along the length of the heater plate.Type: GrantFiled: October 24, 1979Date of Patent: December 2, 1980Assignee: Barmag Barmer Maschinenfabrik AktiengesellschaftInventors: Peter Dammann, Benno Frank
