Patent CS-256390-B2 (CS)
Title: Circular loom
Inventor: HUEMER FRANZ X
IPC: D03D37/00
Filed: 1985-05-31
Abstract: In the circular reed of the circular loom, a plurality of weaving shuttles circulate. Each weaving shuttle has rollers arranged in pairs at its top edge and its bottom edge. The rollers operate together with the corresponding gliding surfaces on the upper shuttle race or lower shuttle race of the circular reed, and each shuttle is supported to circulate on shuttle guide rods by the centrifugal force conveyed by the support elements. The shuttle guide rods of the circular reed define between them a slit in the region of the upper and the lower shuttle races, which slit receives upon opening of the travelling shed one of the warp threads of the upper shed or the lower shed, and form there an upper and a lower rollway, taking up the centrifugal force of the circulating weaving shuttle for the respective pairs of support rollers on the shuttle. The slit widens outside the rollways towards the reed-horizontal median plane to a warp-yarn crossing space. These measures permit a rapid increase of the rotational speed of the weaving shuttle and the utilization of larger warp yarn packages.

Title: Lubricating device of the wheel flange of the railway vehicle
Inventor: RODIG WERNER
IPC: B61K3/02
Filed: 1974-09-19
Abstract: The system contains a lubricant reservoir, a supply conduit to a nozzle at the lubricating point, and an air pressure conduit. The air conduit is connected to a pressurized air source; it opens into the nozzle, and it contains an electrically actuated solenoid valve.

Title: Tractive force regulator for tractor's lifting mechanism
Inventor: TREICHEL RICHARD
IPC: A01B63/00
Filed: 1981-11-13
Abstract: The tractor mounted plough (12) with a three point mounting, has the tractive force transmitted through two bars (16) which are attached to opposite ends of a transverse shaft (28). The force on this shaft causes it to deflect elastically and this deflection is used to control a hydraulic circuit. This hydraulic circuit actuates a hydraulic cylinder which raises or lowers the plough (12) in order to maintain a constant force in the bars. The magnitude of the towing force can be adjusted as required and is indicated by an instrument (48) mounted on the tractor (10).
