IPC: F28G1/16
Filed: 1935-06-11
Abstract: 458,092. Soot blowers. SIMPSON, J. W. L., 67, Mostyn Avenue, Littleover, Derby. June 11, 1935, No. 16837. [Class 99 (ii)] A soot blower for a boiler &c. comprises a cleaning-fluid supply tube 1 which is located longitudinally of a bank of tubes 2 and is reciprocated axially during passage of cleaning fluid therethrough, and one or more tubular members or rakes 11 which branch from the supply tube 1 and are provided with two sets 12, 13 of oppositely-disposed nozzles arranged to project cleaning fluid into substantially all the diagonal gaps between the tubes so that a large number of the tubes are swept tangentially each at four points.

Title: A gun for firing caseless ammunition
IPC: F41B11/723
Filed: 1962-05-02
Abstract: 998,607. Air guns and projectiles therefor. ENGINEERING DEVELOPMENTS Ltd. May 2, 1962 [May 3, 1961], No. 16906/62. Headings F3A and F3C. An air gun comprises a chamber 45 in which air is impressed by means of a piston 46 moved forwardly under the action of a spring 62, the bore 24 of the barrel 16 being connected to the chamber 45 by means of a passage 138 containing a check valve 142 adapted to prevent air compressed in the chamber 45 from acting on a projectile carried on the barrel until the pressure in the chamber 45 has reached a predetermined value which opens the valve 142. The valve 142 includes a spring 148 located between a ball valve 146 and a plug 150 threadably mounted in a tapped portion 152 of the passage 138 for adjustment of the valve. The projectile 110, Fig. 2, is provided with a bore 116 which receives a pair of spaced propellant caps 120, 121 of nitrocellulose ignitable under the effects of heat and pressure. The arrangement is such that on opening of the valve 142, the pressure and temperature of the gas is such as to ignite the propellant caps and cause a pressure differential which closes the valve so that substantially all the energy developed by the ignition is used in propelling the projectile. The gun has a dropdown barrel pivoted at 20 and provided with a locking mechanism comprising a spring-urged latch pin 31 adapted to engage a fixed pin 36, the mechanism being released by means of a transversely extending pin 38. Cocking levers 92, 94 pivoted at 96 move the piston 46 to the cocked position when the barrel is pivoted about the pin 20.

Abstract: 1464430 Selective electro-plating STANDARD TELEPHONES & CABLES Ltd 10 April 1975 [18 April 1974] 16999/74 Heading C7B Articles e.g. electrical contacts are electro-plated in selected areas, by immersing them as cathode in a plating bath in sufficiently close proximity to an anodic wire or ribbon which is continuously passed through the bath. Whereby plating occurs only on an area in juxtaposition with the anode. The wire or ribbon may be made of or coated with the plating metal (e.g. gold, optionally as a coating on stainless steel or Ti) or may be inert with the plating metal being in solution in the bath. The bath may be recirculated with the pump outlet being directed along the wire or ribbon. A subsidiary anode for "flash" coating the whole article may be provided. "Robber" electrodes may modify the electric field in the plating region and permanent or electromagnets may provide desired bath motions. When a soluble continuous loop anode is used, it may be replenished by passage as cathode through a tubular soluble anode of the plating metal in a second bath. The articles may be conveyed through the bath in Co - or countercurrent to the anode.

Abstract: 1,272,411. Coating apparatus. THOMAS FRENCH & SONS Ltd. 18 March, 1970 [2 April, 1969], No. 17140/69. Heading B2L. [Also in Divisions A4, B5 and Dl]  In apparatus for forming upper and lower hems of a curtain, see Division B5, adhesive 49, 71 is applied by a head 44 to a curtain material 12 which has been placed in a well 11 with its top and bottom ends positioned on flaps 13a, 14a, respectively, and clamped by bars 26. A cord 53 is also applied by the head 44 so as to lie parallel to the top edge of the material and in the adhesive coated region of the material and is simultaneously formed into loops 54 on the uncoated face of the material. The head 44 runs on rollers 42 in runways 41 adjacent racks 43. Front and rear adhesive troughs 45 each have a bottom opening brushed by a doctor roll 46 which transfers adhesive to an applicator roll 47 or 48. The troughs 45 are provided with grooves 68a to cooperate with cams on a shaft 68 rotatable by a handle 69 to move the troughs 45 towards or away from the rolls 46 which contact the bottom openings to prevent escape of adhesive or allow adhesive to pass therethrough, respectively. The roll 48 is longitudinally grooved so that when it is rolled on the fabric 12 on the flaps 13a spaced stripes 49 of adhesive are applied. The roll 47 has two flanges to apply two parallel adhesive stripes 71 to the fabric on the flaps 14a. The -rolls 46, 47, 48 are driven by intermeshing pinions one of which 50 runs on the rack 43. On the operative stroke of the head 44, the rolls 47, 48 apply the stripes 49, 71 and, on the return stroke, the pinions 50 are raised from the racks 43 by a cam operated by the handle 69 so that the rolls 47, 48 are raised- and no adhesive is applied.  In a modification, at the end of each operative stroke of the head 44, instead of raising the pinions 50, the racks 43 are lowered out of contact with the pinions 50.

Abstract: 255,079. Burroughs, C. W. July 8, 1926. Retort and like furnaces; discharging. - A furnace which may be used for drying, heating :and finally cooling spent bone-char or other damp granular material comprises an annular shaft divided into drying, heating and cooling sections 61, 62 and 63 and formed between an internally heated inner shell 6 and spaced bevelled rings 12, 22 enclosed within an outer casing 15. The beating section 62 which is preferably lined with fire-brick 620 is heated by means of a burner 8, the combustion gases rising between baffles 612 in the drying zone 61. Between the latter and the casing 15 air is circulated, air inlet 16, Fig. 1, and outlet 17, being provided. The combustion gases leave the inner shell 6 through a pipe 60 and are passed to a flue 9 either directly or indirectly by way of the heating zone by means of a pipe 92 so as to provide an inert atmosphere for the heated char. Air may be introduced into the heating zone through pipes 70 when decarbonization of the bone-char is desired. Surrounding the cooling zone is a jacket 32, water entering at 36 and leaving at 37. Below the water jacket and secured to a girder 53 is a section 41 having a bevelled edge 42 and between this and a corresponding edge of a ring 43 which closely fits the lower section 63, the char is discharged. Means are provided for raising and lowering the ring 43, consisting of bolts 45 having straps 46, 46 mounted on eccentrics on shafts 47, 47. A thermostat 81 connected with a fuel valve 80 permits of temperature control. The lowest section 63 is supported on a ball-bearing base 66 and the section 61 has a bearing upon the top section 64 which is fixed, thus enabling the inner casing 6 to be rotated by means of gearing 67.
