Abstract: 389,187. Washing granular materials. SOC. ANON. DES AUTOLAVEURS BONGERA, 87, Rue St.-Lazare, Paris. Nov. 24, 1931, No. 32589. Convention date, April 15. [Class 82 (ii).] In washing and sorting coal, ores, &c. the material carried by a stream of water down an inclined channel enters a substantially V- shaped syphon device, the heavier particles being discharged through an outlet at the bottom of the syphon into a collecting tank while the lighter particles are carried up the ascending branch to a sieve arranged at the end of or in the length of the inclined channel. Preferably several sorting elements are arranged in series, the screens removing the largest of the lighter particles and allowing the rest to pass through on to a separating device which removes excess water from the system and passes the material into the inclined channel leading to the next sorting element. The syphon device in the inclined channel 1 comprises a downward branch 9 and an ascending branch 2, the cross-sectional areas of the branches being variable by means of an adjustable core 16 and the branch 2 being preferably steeper than the branch 9. The bottom of the syphon is connected by a neck-piece 3, preferably of adjustable cross section, with a tank 4 having a side chamber 5 which may contain an elevator for discharging the heavy particles entering the tank 4. The chamber 5 communicates through a channel 24 having an adjustable weir 25 with the inclined channel 1 on the inlet side of the syphon. An overhead tank supplies water through a valved pipe 21 to the tank 4 so that an upward current may pass through the neck piece 3 and up the branch 2. The lighter particles pass up the branch 2 and into a screen 6, preferably a rotary screen, which retains the largest particles and delivers them to a conduit 38 from which they are discharged. The smaller particles pass through the screen on to a separating device 7 comprising two superimposed plates 30, 31, the heavier particles sliding down the lower plate 31 and passing directly through channels 32, Fig. 6, to the inclined channel leading to the next sorting element. The lighter particles and most of the water pass down the upper plate 30 and fall through an aperture 33 into a hopper 8. The particles sink and are raised by a syphon pipe 35 to the inclined channel leading to the next sorting element, and excess water overflows at 36.

[Classes 38 (iii) and 38 (v)] A cam-shaft electric motor or like controller comprises a frame, a shaft rotatably supported thereby, a plurality of switches supported by said frame in rows disposed in an arc about said shaft, and cams carried by said shaft, each of said rows of switches having associated therewith a common actuating element which is adapted to be actuated by said cams, by rotary movement of said shaft, and thereby is adapted to operate the switches of said row. A cam-shaft controller comprises switch blocks 1 mounted on arms 9 and 10 which are formed on the members 5 and 6. Each switch comprises a moving contact 14, which is biassed into engagement with a stationary contact 13 by means of a spring 24, and is movable to an open position by means of a plunger 25 the projecting portion 35 of which rests upon a rod 40. The rod carries rollers 41 which are moved by cams 60 and 61, the cams 60 being fixed to a shaft 2 and having a slot 62, and the cams 61 being rotatably mounted on the shaft and carrying a pin 63. The cams 60 and 61 raise the plungers 25 to open the switches except when the rollers are aligned with deep notches 65 and 66. When the shaft is turned from a position wherein the notches 65 and 66 are coincident, the cams 61 are delayed until the lost-motion between the cams has been taken up. Continued rotation of the shaft will not effect closure of any switch until the cams 61 are aligned with the rollers 41 and the shaft is reversed to re-align the notches 65 and 66. This return motion of the shaft may be made automatic on release thereof, such action being assisted by the rollers entering shallower notches in the cams. Lost-motion, equal to that between the cams, is provided between the controller handle 4 and a dial 75 so that the time position of the controller is indicated. The invention may be applied to the contro of a multi-speed alternating current motor, a cam 70 affording control of an electromagnetic main switch with no-volt release which is re-set by returning the controller handle to a position intermediate the " off " and first operative positions of the controller.

Abstract: 371,778. Weaving pile fabrics having tufts knotted around warps. ENGEL, K., 14, Colloredogasse, Vienna. Nov. 28, 1931, No. 33061. Convention date, Dec. 1, 1930. [Classes 142 (ii) and 142 (iv).] Relates to carpets, tapestries, coverings, &c. having short lengths of pile threads knotted in the manner of Smyrna or Persian knots around warp threads. In order that the projecting parts a<2> of the tufts may lie adjacent to one another in the carpet &c. in the direction of the warp threads B, as shown in Fig. 5, instead of, as usual, in the direction of the weft threads, as shown by Fig. 2, the jaws of the two knotting nippers, which hold the ends of the pieces of the pile thread, are displaced relatively to one another in the direction of the warp threads when drawing tight the knots. Thus, as applied to knotting nippers of the Renard type producing Smyrna or Giordes knots, wherein pairs of warp threads are lifted from the others and are spread by devices b, Fig. 7, nippers M, N, Fig. 9, entering between the warp threads seizing the ends of the pile thread a, and rotating to loop this around the warps, one of the nippers is displaced in the direction of the warp relatively to the other whilst the nippers are moving in the direction to tighten the knot, as shown in Fig. 11, by means of levers, or a stop. Alternatively this displacement may be effected during the rotation of the nippers, by externally threading one of them and mounting it in an internallythreaded carrying member. The invention is also described as applied to twin knotting devices of the type comprising gripping-jaws M, N, Figs. 14 and 15, formed on tubes m<1>, n<1> and on the cranked ends m, n of rods m<2>, n<2> movable in and with the tubes, which are mounted in a carrier f oscillatable about pivots k to tighten the knot, and are rotated by a rack h and pinions to loop the gripped pile thread a about the warp threads. In this case, one tube n<1> is mounted at a higher level than the other, its end and also the end of its rod being cranked downwardly at 0<1>, Fig. 17, to bring the gripping-jaws M to the same level before rotation, as the gripping-jaws N, whereas after rotation, the jaws N are positioned behind the jaws M as shown in dotted lines in Fig. 20, and remain in this position whilst the carrier .f rotates to tighten the knot as shown in Fig. 15, whereby one limb of the knotted tuft is caused to lie behind the other in the direction of the warp. Alternatively the tubes may be mounted at the same level but with their gripping-jaws arranged at different distances from the plane of the warp threads.
