Abstract: 1301897 Gas distribution systems DUST SUPPRESSION Ltd 24 Nov 1971 [17 Dec 1970] 59867/70 Heading F4X [Also in Division F2] In a gas distribution system comprising a pressure control valve 11 through which gas passes from a medium pressure gas main 10 to a low pressure gas main 12, suppression of the formation and movement of dust particles and swelling of the joint-sealing material in the main 12 is effected by introducing a liquid dispersion into a stream of gas which has left the medium pressure main 10 and is in the course of passing to the low pressure main 12. As shown, a portion of the gas leaving the main 10 passes by way of control valves 13, 14, 15 and 31 and pipes 26, 27 into a cyclone separator 28 wherein the gas is laden with a fine mist or fog sprayed into the separator from a nozzle assembly 39 supplied with liquid from a reservoir 29 by means of a pumping unit 22 which is operated by energy derived from a portion of the gas stream from the medium pressure main 10. Large liquid droplets are removed and settle in the reservoir 29, and the fog-laden gas stream passes from the separator through a pipe 18 to the main 12. The liquid may be a light oil 8, e.g. diesel oil, with or without additives such as steam, water, glycol mixtures, corrosion inhibitors and sealants. A time control 25 automatically regulates the duration of periods of operation of the spray nozzle assembly 39. In a modified embodiment (Figs. 2-5, not shown) a Venturi tube unit (51) supplied with dispersed liquid replaces the spray nozzle assembly, the gas passing through the Venturi unit before entering the separator.

Abstract: 1302499 Toy vehicles COSMO TOYS MANUFACTORY Ltd 5 Nov 1971 51526/71 Heading A6S  A toy vehicle, shown as a toy steam engine 1, Fig. 2, has ground engaging free wheels 2 and driving wheels 3, and carries a length of track 36, 37 spaced above the ground, the track being slidable lengthwise of the vehicle, a track (8), Fig. 4 (not shown) on the track meshing a rack pinion 9, Fig. 6, driven by the vehicle motor 13 to slide the track back-and-forth, stops (10), Figs. 1, 4 (not shown) at each end of the rack in turn engaging a reversing lever 11 which changes the direction in which the track slides, the gearing connection 19-25 and between the motor 13 and the drive wheels 3 including a ratchet clutch 26. The arrangement is such that when drive is transmitted from the motor 13 through the ratchet clutch 26 to the driving wheels 3 so that the vehicle moves forward, the track 36, 37 is slidden backwardly slowly, relatively to the vehicle, until the stop (10) at one end of the track actuates the reversing lever 11: the track 36, 37 is then slidden forwardly quickly with respect to the vehicle, which itself continues to travel forwardly under its own momentum, the ratchet clutch 26 over-running. The reversing lever 11 acts to slide a reversing shaft 12 axially against the biass of a spring 18. In the position shown, drive is transmitted from the motor 13 through gears 19-21, 16, 15, 22-25, &c. In the second position of the reversing lever 11, the gear 15 is slidden out of mesh with the gear 22, and a gear 17 is instead slidden into mesh with a gear 28 rotating with the gears 23, 24. The rack pinion 9 is fast for rotation with the gear 22. A snail cam 29, fast with one ground wheel 3, actuates a follower (30), Fig. 7 (not shown), connected to a figure 31, Fig. 2, so that the latter slowly rises and then falls suddenly as the vehicle progresses. The motor 13, which is electric, is powered by batteries in a compartment closed by a lid latched by a motor on-off control switch 35. The track sections 36, 37, Fig. 5c have interengageable tongues 39, 40 and slots, lugs 41, 43 at the tongue ends fitting into notches 42, 44 and a catch 45 then being turn to lock the two sections together.

Abstract: 1303571 Impact wrench DESOUTTER BROS Ltd 30 April 1971 12319/71 Addition to 1180771 Heading B3N In a power-operated impact wrench or screwdriver as claimed in claim 1 of the parent Specification, the inertia means is supported on and moves axially of the hammer member to act upon, and be acted upon by, axially resilient means.  As shown, the hammer member comprises outer and inner rings 29, 30 circumferentially located by balls 40. Keyed to the inner ring for axial movement thereon is an inertia cylinder 33 which is urged by dished annular springs 36 into abutment with balls 38 which act between similar depressions on facing surfaces of the outer ring 29 and inertia cylinder 33. The stressing of springs 36 is adjustable by moving a rear abutment member 39. In operation, when anvils 27 exert a predetermined back torque, on hammers 28, slight relative rotation between the outer and inner rings 29, 30 causes balls 38 to move slightly from their depressions, thus moving inertia cylinder 33 axially to compress springs 36. The subsequent expansion of these springs against the inertia cylinder 33 results in a kick being applied to the hammer member. The latter thus moves rearwardly to cause a flange 51 thereof to actuate a plunger 21 to close a valve 19 and thereby cease actuation of the pneumatic vane motor 6. At back torque values below the predetermined maximum the springs 36 exert such a force as to prevent the relative rotation between the rings 29, 30; thus the motor continues to be driven, and the hammers and anvils engage and disengage cylindrically.
