Title: Electrically weldable thermoplastic sleeve for pipework, etc. - has resistance heating wire close to inner wall
IPC: F16L47/03
Filed: 1984-09-03
Abstract: The sleeve, bush or socket is used to weld joints in pipework, drainage systems, moulded details, valves, etc. The electrical resistance wire can be connected directly to a supply circuit without any controls being necessary.

Patent NL-8902496-A (NL)
IPC: B62D21/18
Filed: 1989-10-06
Abstract: In an air spring system for a vehicle with spring brackets (2) fitted to the underside of the frame (1), each bracket (2) carrying pivotably a supporting arm (5) to support a wheel axle (shaft) (10) and air springs (11), there is a tranverse connection (3) between the brackets at the level of the pivot connections (4) of the arms and inclined supports (struts) (12, 13) connect the central part of the transverse connection (3) to the frame (1) in points right above the brackets (2). The supports ((12, 13) have webs in a vertical plane and are connected thereby to a vertical web op the transverse connection so that their neutral zones as to bending intersect each other in a point on the transverse connection lying in a horizontal plane through both pivot connections (4). This gives a light structure with very good possibility to take up transverse forces even if the frame of the vehicle in that zone is not very rigid, e.g. by lacking transverse connections between side beams to provide room for the taking up loads with low parts extending between such side beams.

Title: Method and device for bending sectionsheet,plate,strip and like material
IPC: B21D11/20
Filed: 1977-06-17
Abstract: A sheet folding or bending machine has the surface of the bend stamped at the bottom along a straight line at right angles to its length, made radially to a parallel shaft on the same side of the sheet. The suspension elements are spaced closely together before the start of this stamping action, with corrugations which interlock so as to allow the inside of the sheet to bend.
