Title: Tubular stretch closed end material smoothing device, for stockings or tights
Inventor: PROPACH HANS-WALTER
IPC: D06C5/00
Filed: 1991-09-24
Abstract: The unit(s) feeds and stretches the material on a longitudinal former. The heater heats it on the former. The material is initially gathered to be taken by grips which move along the former to draw the material over it and peel it on.     Pref. the grips are inserted at least partially into the sides of the stocking gathering station to hold the material and spread it outwards, with grip(s) tilting w.r.t. the other against a limit stop to hold the stocking fabric between them. When the gathered stocking has been drawn over the former, the grip is tilted back to release it from the limit stop, and both grips are parallel to each other. The tilting grips is moved alternately between a setting against the limit stop and parallel to the other grip while they are moved along the former, to draw the stocking material over the former. The frequency of the tilting action is controlled w.r.t. the relative speed between the grips and the former. The two outer grips, with a gripping prong, flank a U-shaped gripping head with tilting legs as gripping prongs. Each limit stop is a rubber buffer. The stocking is gathered by two displaced plates with continuous belts between them which project at least partially beyond the plates, with two double-belts with parallel belts where one travels against the other. Guide bars between the plates, over the belts, project at least partially beyond the long end surfaces of the plates. The former has curved U-shaped stretcher(s). A turntable, rotatable on a vertical axis, carries formers (11), with separate stations for the feed and stretching units and the heaters, for the turntable to rotate between them. A unit to withdraw the stocking is after the heater at the former. The stretchers are suspended at the turntable, with their rounded ends downwards. A light unit with a flat illumination is directed at the stocking on the former for visual control. The stretchers swing on a holder at the turntable between an aligned assembly and an assembly pushed to one side of the alignment. The stretchers swing parallel to each other for the stocking to be drawn off at the take-off station by two belts which extract the stocking from the sides of the stretcher, and pass the stocking to a lateral folder with two belts and a folding slide and a stiffening sheet is inserted for packaging.

Title: Misfire discriminating method for engine
IPC: F02P17/00
Filed: 1991-10-30
Abstract: The method of discriminating misfire of any cylinder of a multicylinder engine comprises the steps of discriminating a cylinder number (#i) at a present combustion stroke (S101) . A present momentum is claculated for the present combustion stroke, in a period in which no combustive work is done (S105). A second momentum for a second stroke preceding the present combustion stroke by two strokes, is computered in a period in which no combustive work is done (S106). The present and second nmomentums (S107) are averaged. A momentum is desired for a stroke preceding the present combustion stroke by one stroke, in a period in which no combustive work is done (S107). A difference between the averaged momentum and the momentum (S107) is taken. A misfire judgement level from a map of combustion conditions is set as a function of the momentum and engine load data (S108). The difference is compared with the misfire judgement level (S109).

Title: Relaxation swing
Inventor: CZINKI LASZLO DR
IPC: A63G9/12
Filed: 1993-03-20
Abstract: A relaxation and at the same time fitness swing possesses, as is customary, a supporting framework with crossbeam on which a swing pendulum, here of ring-shape design, is pivotably arranged. This swing pendulum is equipped with a traction rope which is actuated from a pivoting lever located in front of the swing seat and which, guided along the ring, engages on a cantilever arm which is fastened to the supporting frame and projects at a distance beyond the pivoting joint. By pulling and releasing the traction rope, which is fastened at one of its ends to the pivoting lever, the swing pendulum together with the swing seat mounted thereon is set in swinging movements, this being effected via hand and foot simultaneously since the pivoting lever is equipped with handles at one end and with footrests at the other end. A uniform stress which, advantageously, acts on many parts of the body is thus possible, with the result that many muscles can be simultaneously stressed when the relaxation and fitness swing is activated. <IMAGE>

Title: Inexpensive tubular low-friction bearing prodn. - comprises injection-, transfer-, etc. moulding thin inner low-friction layer on core, using fibre-free material and abrasive filler(s)
IPC: F16C33/20
Filed: 1993-04-08
Abstract: Prodn. is from a suitable low-friction polymer layer in an outer layer which is also a polymer. The inner thin low-friction layer is injection transfer, or injection/blow moulded on a coare, using material free from fibre and/or other form of abrasive fillers. The prod. is covered with a hard or a soft elastic polymer to which the low-friction layer bonds firmly. The low-friction layer is completely or partly removed radially at at least one point on its circumference. The complete or partial slit formed is filled with the material of the hard or soft polymer, and finally the covered low-friction layer is sepd. off its inside core. The low-friction layer is pref. one of polyethersulphone, polyetherketone, polyamideimide or polyetherimide. A pref. hard polymer is e.g. polyoxymethylene, polyamide or polybutylene-terephthalate. Pref. soft polymres are thermoplastic elastomers, nitrilebutadiene or acrylic rubber or silicone rubber. Slotted layer has the core (1) moulded in a split mould tool, with the space (3) to form the tubular low-friction layer (4). The mould preferably has radial runnrs. A suitable polymer is cured or solidified in this space (3) and the next outer polymer (6) is formed by a suitable process, so that it bonds to the low-friction layer (4). The low-friction layer is stripped off. The outer layer (6) can be subdivided into more than one part and it is advantageous to use a polymer with 5-80% content of fibrous or other fillers. Using an elastomer in theis layer (6) damps down noise or vibrations. The low-friction layer (4) is best made with several longitudinal slots (7) filled with the adjacent outer material (6). ADVANTAGE - The method is inexpensive, simple and environmentally favourable. The prod. can be made to close tolerances. The low-friction layer can be down to 0.2 mm thick or even less.
