Patent FR-2196854-A1 (FR)
Title: Vibrating screen with plastic tubes - suitable for processing wet coal etc
IPC: B07B1/12
Filed: 1972-08-23
Abstract: Each layer of the screen consists of a frame with a number of round crossbars, the bars bearing an equal number of plastic tubes. The i.d. of each tube is somewhat greater than the o.d. of each bar. The bars and rods lie in the direction of vibration. In operation, material passes through the screen and rotates the tubes, preventing material from adhering to them and therefore eliminating clogging of the screen. To save weight the tubes are made of low-adhesion plastic material and they can be set with fine gaps.

Patent FR-2219121-A1 (FR)
Title: Cyanide effluent purication - by successive absorption in cationic, weak anionic and strong anionic resin beds
IPC: C02F1/42
Filed: 1973-02-26
Abstract: The effluent is treated by (1) ion exchange in an acid cationic resin bed to fix cations and in a weak basic anionic bed to fix complex anionic cyanides and a strong basic anionic bed to fix CN, (2) dissolving an oxidising agent for the cyanide deposit in the cationic bed (3) regenerating the resins and destroying cyanides by strongly basic oxidation. The oxidising agent is a persulphate, monopersulphuric acid, H2O2 or Javel water. The use of oxidising agent in (2) prevents accumulation of cyanide deposits which increase CN- concn. and reduce efficiency. Use of the weak basic bed immediately after the cationic bed protects the strongly basic anionic bed from irreversible reaction with complex cyanides.

Patent FR-2278550-A1 (FR)
Title: Articulated vehicle curve tracking - by using chassis end displacement measurements to vary bearings
IPC: B61F5/44
Filed: 1974-04-19
Abstract: The adjacent ends of two chassis ends rest on a "false" chassis via roller elements. The rotation of each chassis relative to the false chassis is controlled by applied forces by attachments on each chassis. The control is obtained by friction. The radial displacement directly limits the limiting force via a system of mechanical multiplication, also giving a proportional force applied to friction restraint. The attachments to the chassis are rods, virtually parallel to the longitudinal axis of the false chassis, with sleeves at the rod ends, one fixed to the chassis. Flexible fixings are used with these rods.

Title: Compact articulated reduction gearing - has balls acting as both bearings and planet gears with preload eliminating whiplash
IPC: F16H13/08
Filed: 1975-07-15
Abstract: The compact articulated drive reduction gearing for output shaft rotation has no play in its moving parts and is consequently very rigid. It provides large reduction ratios of order 100 to 250. The input shaft (37) is supported in a fixed sleeve (36) and drives a bevel gear (16) via a pinion (38). An adjustable keyed sleeve (10) is used to mount the gear on two back-to-back circular ball tracks (9). The tracks are split and one half (7) rotates with the output flange (20) and arm (4), while the other (8) is supported on the fixed sleeve (36). A cross shaft (21) is used to apply a pre-load across the output flanges to take up any backlash. The balls perform both the bearing and also the planet wheel function in the gear train, thus keeping the design compact. They may be substituted by conical pinions. In addition, the input shaft and pinion may be replaced by a self-contained hydraulic motor.
