Abstract: 342,272. Kinematograph apparatus. MACDONALD, A. E. and BLUNT & McCORMACK, Ltd., 20, Bedford Street, Strand, London. Oct. 28, 1929, No. 32674. [Class 97 (i).] A fixed plate 1 and a plate 2, parallel thereto and movable perpendicularly to the plates, are provided at the entrance to a spool box to prevent the passage of fire into the box. The plate 2 is urged towards the plate 1 by a spring 11 but is normally held from it by an apertured plate 6 forming a pawl engaging a notch in a rod 4 secured to the plate 2. An electromagnet 10 is energized in known manner when the film ignites or runs irregularly and moves a sleeve 9 rearwardly so that a chamfered part of its edge moves the pawl out of engagement with the notch and permits the spring 11 to push the plate 2 on to the film and plate 1. The parts may be housed in a casing 3 having a rearwardly extended container 12.

Title: Improvements relating to fuel burners
Inventor: GRAY JAMES STUART AUSTIN
IPC: F23D17/00
Filed: 1954-11-11
Abstract: 819,133. Pulverulent fuel burners. MITCHELL ENGINEERING Ltd. Feb 10, 1956 [Nov. 11, 1954], No. 32700/54. Class 75(1) A burner for pulverulent fuel comprises at the burner face a nozzle for the passage of air surrounded by a series of concentric annular nozzles at least two of which serve to convey air-laden pulverized fuel each of these latter two nozzles being supplied through a separate volute chamber and being spaced from the next pulverised fuel nozzle by an annular nozzle for the passage of additional air. In order to eliminate furnace flash back the pulverized fuel passes through a restriction to create a zone of high velocity on its way to a nozzle and such zone may be located between the volute chamber and the nozzle. An adjustable device controls the distribution of the pulverized fuel to the nozzles and rotary motion is imparted by swirler blades to the fuel mixture and to the secondary air. A burner for liquid fuel is arranged axially within the central nozzle and can be burned simultaneously with the pulverized fuel or used solely for ignition purposes. As shown, the burner includes a centrally arranged oil tube 10 and an air tube 13 surrounding it through which tube 13 primary combustion air passes under pressure from a wind box and is admitted to the tube by an adjustable butterfly valve 14 or damper. Stationary swirler blades 15 impart a rotary swirl to the air as it emerges from the tube 13 to mix with the cone of fuel oil from the oil burner 12 and constitutes a stable ignition point at which an electric igniter may be provided for the liquid fuel. Annular nozzle 16 for the fuel air mixture communicates through a throat 17 and a duct 18 with a volute chamber 19 terminating in a tangential duct 20, Fig. 3. The duct 18 is surrounded by a further secondary air duct 21 leading from the wind box to an annular nozzle 22, the air passing adjustable vanes 23 which when open provide the air with a degree of rotary motion which is enhanced by fixed blades 24, mounted between two rings 25, 26, located in the duct 21. A further annular fuel-mixture nozzle 29 communicates through a restriction 28 with a volute chamber 30 fed from a tangential fuelmixture intake 31, Fig. 3, a damper 32 hinged between the two fuel-mixture intakes 20, 31 being adjustable to vary the ratio of the quantities of fuel passing through these ducts. A further secondary air nozzle 33 surrounds the nozzle 29 and communicates with the wind box through adjustable vanes 34 which impart a swirling motion to the air passing through. A refractory quarl 35 surrounds the front face of the burner. The vanes 23, 34 are adjusted by pin and slotted lever mechanisms 36, 45 operated by guide-ring mechanism through hand wheels 43, 48.

[Classes 64 (i) and 64(iii)] [Also in Group XI] A heater for fitting to a hot-water tank comprises a tube b within the hot-water tank a extending upwardly and open at its upper end and bent so as to provide a short, substantially horizontal portion c which extends through the tank wall and is closed at its outer end, an opening in or adjacent to the bend of the pipe communicating with the lower part of the water space, means being provided for heating the horizontal part c of the tube outside the tank. In the drawing, communication with the lower part of the water space is by way of a return pipe l which is mounted concentrically within the horizontal tube portion c. Alternatively a hole x may be provided. The horizontal tube portion c outside the tank may be heated by a gas burner (as shown) or an oil burner, in which case fins p are provided on the pipe c or an electric heating element may be used. The heat source may be controlled by a thermostat, the temperature-sensitive portion of which extends into the water space.
Patent GB-801724-A (GB)
Title: Improvements relating to the prevention of knot-slipping of synthetic resinous filaments in the production of nets
IPC: D06M15/333
Filed: 1955-11-16
Abstract: In the production of nets by knotting single filament synthetic resin threads, slippage of the knots is prevented by treating the filaments, before or after fabrication, with a solution containing a solvent for the filaments which is incapable of reacting with the filaments, a diluent miscible with the solvent which is incapable of dissolving the filaments and polymer which is insoluble in water and does not swell therein but which is miscible with the synthetic resin of which the filaments are composed and which is soluble in the solvent-diluent mixture and allowing the solution to dry.  In the case where the filaments are treated prior to netting, the polymer is softened upon the net by heating or by solvent action.  The diluent may evaporate more rapidly than the solvent.  In examples: (1) nylon filaments are treated with a composition comprising polyvinyl formal, formic acid, acetone and a synthetic rubber produced from adipic acid and hexamethylene diamine.  Nets knitted from threads so treated are heated to 70 DEG  to 80 DEG  C. while stretching in at least one direction.  (2) A solution containing polyvinyl formal, formic acid and acetone is applied to a nylon filament and a net knitted therefrom is wound upon a cylinder thereby stretching it and is immersed in a mixture of ethanol and toluene or heated in an atmosphere containing the vapours of these compounds.  (3) Example (1) is repeated using a treating solution comprising butadiene-acrylonitrile rubber, phenol, acetic acid, toluene and methyl ethyl ketone.

Abstract: 1,116,981. Preventing overturning. ETABLISSEMENTS F. POTAIN & CIE. 2 Aug., 1965 [5 Aug., 1964], No. 32913/65. Headings B7D and B7J. In a stabilizing device, e.g. for mobile cranes, similar to that described in Specification 899,486, a pair of outrigger arms 2 are extended by a ram 3 to a point where further extension of the arms is prevented and a triangular member 5 is rotated in a direction to urge a link 16 downwardly. The link 16 is pivoted to a bracket 13 which mounts a wheel or wheel set 14 and is pivoted to a pair of links 10 and 11 pivotally connected to the vehicle. The wheels 14 are urged downwardly by the rotation of the member 5. In this position the ram 3 may be connected to a hydropneumatic spring device so that the vehicle can be moved with spring suspension. In the inoperative position of the apparatus, the wheels 14 are mounted on the vehicle body. In a modification, Fig. 3, the wheels 14 may be mounted on half axles 19 pivoted at 18 to the vehicle and connected by a crank 6 to the member 5. In another modification, Fig. 4, the arms 2 press against bellcrank levers 23 which are connected by links 16a to the wheel supporting links. In a vehicle having four stabilizing devices 3, hydraulic power is supplied from a pump 39 under the control of a valve 40, there being an individual valve 46 for each stabilizer. Fluid may be supplied either through line 37 or 38 to one side or other of the piston 32 of the stabilizer, the line 38 including a one-way valve 29 which may be tripped by pressure in line 30. The valves 46 are operated by air pressure from a compressor 47. To extend the stabilizers, a valve 49 is operated to apply air pressure to the valves 46 and valve 40 is placed in the position to apply fluid pressure in line 38, line 37 being opened to exhaust. Valves 44 are operated simultaneously with valves 46 to isolate one side of pistons 32 from the other. Release of air pressure from the valves 46 and 44 now locks the fluid in the stabilizers 3 and connects the opposite sides of pistons 32 to each other and to the hydropneumatic springs 45. To retract the rams in the stabilizers, valves 44 and 46 are actuated and pressure fluid is applied to line 37 by operation of valve 40. The fluid pressure in line 30 trips valve 29 to open the sides 33 of the pistons 32 to exhaust.
