Title: Hydrostatic piston engine - has choke channel as thread groove on threaded pin fixed in bore in piston
IPC: F01B1/06
Filed: 1973-10-15
Abstract: Hydrostatic piston engine with a cylinder block which can turn about a journal and which carries pistons distributed on the periphery of the cylinder block where the pistons, at their outer ends have feet with flat support faces, which are guided along flat guide faces of a guide section, arranged tangential to a circuit, which is eccentric to the axis of the cylinder block. In each support face is a recess for the hydrostatic support of the piston and this is connected with the front face of the piston via a choke channel. The choke channel has the form of a thread groove (20) of a thread (21) formed on a threaded pin (22), which is fixed in a bore (23) in the piston (3).
Patent CH-593849-A5 (CH)
Title: Winding sleeve mounting - uses sprung pawls to give lock and quick release actions to secure sleeve to winding shaft
IPC: B65H75/08
Filed: 1975-11-24
Abstract: To mount a sleeve to a winding machine, a clamping cone slides on the winding shaft. The clamping cone has wedge-shaped pivoting pawls pressed by springs against the winding shaft, which hold the clamping cone against any tendency to slide, and which can be released. A ring and limit stop slides on to the clamping cone to overcome the pressure of the springs on the pawls when the clamping cone is moved in a sliding action on to the winding shaft. The pressure of the springs on the pawls ensure that the clamping cone is held firmly on the winding shaft to resist sliding forces two opposing directions, but allowing a quick release action.

Title: Elastic coupling for variable number of torsion bars - has friction damper impulse protection to reduce fluctuations
IPC: F16D3/60
Filed: 1973-03-14
Granted: 1974-10-11
Abstract: The coupling housing consists of two face plates one of which is supported by a stub shaft running in a bearing housed in the other plate. Input and output connections are paraxial. The coupling between the two plates is made by a system of torsion bars and jointed connecting rods arranged so that a group of bars is fastened to one plate and a second group, perpendicular to the first, fastened to the second face plate. The magnitude of couple to be transmitted can be accommodated by increasing the number of torsion bars in a group between the plates. To correct violent fluctuations in torque a damper is interposed between the plates and consists of an adjustable friction band anchored to one plate and acting on a brake drum integral with the second plate.
