Abstract: 692,318. Animal traps. HILL, W. E. Jan. 23, 1952 [Jan. 23, 1951], No. 1677/51. Class 5(i) Animals, such as rabbits, are trapped over a wide area enclosed by posts 5 and net 24 by employing catches on each post which are released electrically from a distance to cause the net to rise to trapping position from an inoperative position on the ground, As shown, the net, pinned to the ground at its lower edge, has its upper edge hooked to supports 7 sliding upwardly in slots 6 on the posts when a counterweight 13, Fig. 2, is released by energizing a solenoid 22. The armature of the solenoid is connected to a plate 19 having a key-hole slot 18, the enlarged part of which releases the weight connected to support 7 by a cord 11 passing over a pulley 12. A spring-operated pivoted catch 8 retains the support 7 in raised position. The apparatus may be transported on a vehicle having drums on which the net and electric leads are wound.

Title: Method for adsorbing contaminating vapours from gaseous medium
IPC: B01D53/22
Filed: 1958-01-27
Abstract: <PICT:0836283/III/1> In a process for separating gases and vapours, and especially removing solvent vapours from air, a porous layer of a finely-divided absorbent is built upon a filter surface by suspensing the absorbent in the gas to be treated in high concentration, and moving the suspension to a filter surface on which the absorbent separates as a porous layer on the ingoing side of the surface, and then the contaminated gas passes alone through the filter surface which removes the vapours therefrom. Sufficient absorbent is dispersed in the gas to build up a layer 1/8 to 1/2 inch thick; activated carbon, alumina, or silica gel of mesh size minus 200 to plus 35 (Tylor) may be used. The vapours removed include solvents, halogenated hydrocarbons, or acidic gases such as H2S, SO2, or phosphine.  In a suitable apparatus, a stream of gas passing through a duct 12 draws into it finely divided absorbent 36 to form a concentrated dispersion which passes into the plenum chamber 20 on which a number of porous filter elements 28 are mounted containing a filter bag of cotton or synthetic fibre.  The absorbent deposits on the filter surface as a porous coating of 1/4 inch thickness, and the contaminated vapours are then passed alone, through the filter thus formed.  The air freed from vapours passes to an exit 16.  At intervals a further layer of fresh absorbent may be formed on the filter element.  The exhausted absorbent may be removed by agitating the filters by a handle 32 or by reversing the air flow through the filter bag.  U.S.A. Specifications 2,137,254 and 2,143,664 are referred to.

Title: Strand handling apparatus
IPC: D07B3/00
Filed: 1938-01-28
Abstract: 489,268. Variable - speed gearing. STANDARD TELEPHONES & CABLES, Ltd. Jan. 28, 1938, No. 2805. Convention date, April 10, 1937. [Class 80 (ii)] [Also in Group XXV] The forward speed of the advancing strands of a cable-stranding machine is regulated by means under the control of a rotatable member in frictional contact with the strands and operative to vary the speed of the drive in such a way as to maintain the forward speed in a constant ratio to the angular speed of twisting. The cable 17 drives a wheel 51 on a shaft 53 to which is fixed a gun gear 54. Planet gears 55 mesh with a ring gear 61 and with the gear 54. The gear 61 is driven by sprockets 62, 64, and by other connections, from a shaft 15 at a constant speed which is so adjusted that the planet gears 55 are held stationary in space so long as the cable travels at the desired linear speed. The gears 55 are mounted in a yoke 56 on a shaft 57 which is coupled with the rotor shaft of an electrical generator 58. When a layer of cable on the drum 44 is completed and the linear speed of the cable therefore tends to increase, the yoke 56 turns the rotor of the generator 58 and current passes thence to a motor 80. A screw 78 geared to the moor 80 then rotates and a ring 76 engaging friction cones 74 is traversed thereby. The cones 74 are integral or rigid with planet gears 72 which mesh with a ring gear 73 and a sun gear 71. The shaft 15, through gears 67, drives the sun gear shaft 68 and the ring gear, through gears 85 &c. drives the drum 44. When the ring 76 is stationary the speed of the drum is constant but when the linear speed of the cable tends to increase as above described the ring 76 takes up a new position which compensates for the increase by reducing the speed of the drum. The drum may be driven electrically and the flier may rotate about the take-up instead of about the supply. British Specifications 357,235 and 357,236, [both in Group XXXVI], and U.S.A. Specification 1,673,284 are referred to.
