Title: Improvements in or relating to the antenna system of an object locating system
Inventor: TASKER HOMER GOLD
IPC: H01Q3/32
Filed: 1950-12-11
Abstract: 704,341. Radar. GILFILLAN BROS., Inc. Dec. 11, 1950, No. 30224/50. Class 40 (7) An aerial system, of particular use in an object locating system wherein a beam of pulsed radio energy is directed to repeatedly scan an area, includes a parabolic reflector having a supplementary reflector mounted thereon in such manner as to render the beam assymmetrical. The system may comprise a portion of a cylindrical parabolic reflector 32 illuminated by a linear array of dipoles 31 substantially at the focus thereof. The array may be backed by reflector 34 and fed by probes extending into waveguide 36 the width of which may be varied to cause the beam to scan in a plane perpendicular to the paper. The shape of the beam in the plane of the paper is modified and rendered assymmetrical by the use of auxiliary reflector 33 bolted on to the main reflector. An alternative position of the auxiliary reflector which causes assymmetry to occur giving the mirror image of the first assymmetric pattern is shown dotted. The transmitter, receiver, and indicator of a .ground control approach system are shown in schematic form on Fig. 4. Fig. 1 shows the aerial system 10 mounted off the runway 41 watched by the G.C.A. system of which it is a part. If the aerial scan is in elevation, i.e. in a vertical plane, it is desirable that the radiolocation system shall view the whole length of the approach path as shown hatched from'topright to bottom-left. The aerial system of the present invention giving a pattern similar to that shown hatched from top-left to bottom-right will do this with a minimum of sensitivity in areas not of interest. An aerial according to the invention is also of use for the azimuth scanning aerial of the same system for which similar considerations apply. A unidirectionally expanded display may be used,.

Title: Improvements relating to a pressure regulating device for oilburners
IPC: G05D16/10
Filed: 1958-09-24
Abstract: 898,217. Valves. LIAGO S.A. Sept. 24, 1958 [Feb. 21, 1958], No. 30537/58. Class 135. [Also in Group XI] A valve block for regulating the oil supply to a burner of the return flow type comprises a piston 42 controlling a valve 30 supplying oil through an outlet 46 to the burner, a piston 13 controlling a valve 10 through which the returned oil flows through an outlet 4 to the tank, a piston 25 responsive to the returned oil pressure, a pivoted lever 5 having one end abutting a piston-rod 24 extending from the piston 25 and the other end abutting a piston-rod 8 having a squared lower end slidable in an aperture in the piston 13, and a spring 11 acting between the piston 13 and the piston-rod 8. The oil is delivered from a pump (not shown) to an inlet 45 in the valve block and the returned oil from the burner is delivered to an inlet 20 in the valve block. The lower end of the valve 30 co-operates with an aperture 32 to supply oil to the burner and the upper end of the valve 30 co-operates with an aperture 27 in piston 42 to control the flow of oil to a duct leading to the oil tank. The piston is slidable on the squared end of a piston-rod 39 and is urged downwardly by an adjustable spring 41 to close both apertures 27 and 32. Increase in oil pressure raises the piston 42 and a spring 31 acting on the valve 30 causes the valve to follow the piston until arrested by a flange on the valve engaging a fixed stop. The aperture 32 leading to the burner therefore opens and the aperture 27 leading to the oil tank opens later if the pressure raises the piston beyond the upper limit of movement of the valve 30. The spring 41 acting on the piston 42 is adjusted by a screw 33 abutting the outer ring of a ball bearing 36 transmitting the pressure to the piston rod 39 via a boss 37 on the end of an oscillating coupling rod connected to an eccentric on a motor. The piston is thus continuously oscillated about its longitudinal axis to prevent sticking. The valve 10 co-operates with an aperture 9 in the piston 13 and the spring 11 acting on the piston 13 is adjusted by tilting the lever 5 about its pivot 17 by means of a motor. The piston 13 and the piston 25 are also continuously oscillated. The returned oil passes through a non-return flap 19 before reaching the pistons 13, 25. The inlet 45 is also connected to the outlet 4 leading to the tank by an electromagnetic valve 2 which is closed when the burner is to be ignited.
Patent GB-761075-A (GB)
Title: Improvements in the treatment of sheets or webs of thermoplastic materials
IPC: D06Q1/02
Filed: 1953-11-05
Abstract: 761,075. Finishing fabrics. BLEACHERS' ASSOCIATION, Ltd., WHITELEGG, C. J., and BARRETT, F. L. Nov. 4, 1954 [Nov. 5, 1953], No. 30556/53. Class 42 (1). [Also in Group XV] Ornamental effects are produced on sheets or webs consisting of or containing thermoplastic substances capable of shrinking when heated to an elevated temperature below the melting- point, by bringing about shrinkage of localized areas of such sheets or webs, without appreciable melting, by means of radiant heat. The heat may be applied to localized areas, other parts being protected therefrom by a heat-resisting screen, e.g. a stencil, or heat may be applied to the whole of the sheet or web, and localized areas may be protected from shrinkage by a resist printed thereon, the resist being subsequently removed. The resist may comprise a water-soluble adhesive, and may contain additional substances such as dyestuffs and heatresisting, heat-insulating or heat-reflecting substances such as asbestos, magnesium carbonate, French chalk or metallic powder. The thermoplastic material, which may be, e.g., a cellulose ester, polyethylene, vinyl polymer, vinylidene polymer, linear superpolyamide or linear superpolyester, may be present as fibres forming all or some of the yarns, or as a portion of the fibres composing the yarns, of a woven fabric. Substances such as plasticisers may be present. The sheet materials may be dyed before or after the differential shrinking. In examples, a fabric woven from yarns composed of a terephthalic acid ethylene glycol polyester is ex. posed to radiant heat through heat-resistant stencils; another such fabric is printed with a calico printer's Gum Senegal thickener, dried, and passed on a travelling conveyer beneath a battery of infra-red units. The gum is then washed out with hot water. According to the Provisional Specification, heating may also be by means of hot air, or by a liquid bath having no chemical or solvent action on the thermoplastic substance, e.g. mineral oil, tetrahydronaphthalene, chlorbenzene, xylene or a lowmelting metal or alloy.

Title: Improvements in apparatus for controlling the operation of mechanical stokers
Inventor: HAYWARD CHARLES HENRY GEORGE
IPC: F23H11/20
Filed: 1957-10-01
Abstract: 856,942. Controlling mechanical stokers. DANKS & CO. (OLDBURY) Ltd., E. Sept. 30, 1958 [Oct. 1, 1957], No. 30660/57. Addition to 745,661. Class 51 (1). In a furnace having a travelling grate and a firedoor regulating the depth of fuel on the grate, any two of the controls for adjusting the firedoor, the speed of the grate and the air supply are linked by a lever, and adjustment of the third control alters the velocity ratio of the lever so that the speed of the grate or the air supply is adjusted to keep the fuel/air ratio constant. A lever 63 on the firedoor control shaft 57 is connected by the inner wire 61 of a flexible cable to one end of a control rod 87 sliding horizontally in guides mounted on the casing of the grate speed regulator. The control rod 87 is biased by a spring 93 towards its free end, and its middle part 87C. An operating rod 40 for the forced draught damper, sliding vertically in guides on the regulator casing, is downwardly biased by a spring 110, and carries a pin 108 passing through a flat-sided part of rod 40 and engaging slots 133 in the arms of a clevis at the end of a lever 109 pivoted to the mid-part 87C of the control rod. A wear-resistant liner carried by the other arm of the lever 109 engages a cam 35 secured to the shaft of the control hand wheel of the grate speed regulator. Adjustment of the firedoor moves the control rod 87 through cable 61 and the effective velocity ratio of the lever 109 linking the grate speed control to the damper is altered by the movement of the pin 108 relative to the slots 133 in the forked end of the lever. Since the slots 133 are inclined to pass below the pivot of the lever 109, the damper control rod 40 is moved vertically by horizontal movement of the pivot of lever 109, so that the damper is adjusted by movement of the firedoor, independently of the grate speed control, while adjustment of the grate speed control automatically adjusts the damper setting through cam 35 and lever 109. Manually adjustable air supply or firedoor controls may be linked by a lever to the stoker speed control, the velocity ratio of the linkage being varied by a manually operable firedoor or air supply control, or the movement of the firedoor may control the air supply through a lever linkage, manual adjustment of the stoker speed altering the velocity ratio of the linkage.

Title: Apparatus for volumetrically dosing and uniformly spreading poorly flowing or non-flowing loose material such as wood shavings or the like
IPC: B27N3/14
Filed: 1960-09-07
Abstract: 957,299. Endless conveyers; shoots. HILDESHEIMER MASCHINENFABRIK BEHRENS & CO. G.m.b.H. Sept. 7, 1960 [June 23, 1960], No. 30806/60. Headings B8A and B8S. In preparing material, e.g. wood chips or shavings, for moulding, the material is fed to a tube 2 which is moved to and fro by rotation of a vertical shaft 5. The inclination of the tube is adjustable and the material is distributed symmetrically over the width of a receptacle 1. A shoot 8 is pivoted on the receptacle and the lower end of the shoot is oscillated by cams 14 engaging rollers 13 provided on the shoot. A stationary plate 9 adjustable by screws and nuts 10, 11 coacts with the shoot and has devices 17a, 17b for maintaining the height of the material in the shoot between predetermined limits. A pinned or toothed roller 16 extends across the width of the discharge end of the shoot 8 and is intermittently rotated, e.g. by a ratchet. An endless conveyer 18 is provided with a brush 39 for removing particles of material and endless chains 34 fitted with spikes 36 co-operate with the conveyer to distribute the material into moulding boxes 37 supported on a conveyer 38. Alternatively, the material may be conveyed away for treatment elsewhere. The chains 34 are driven at higher speed than the conveyer 18. The cams 14 are so formed that the shoot 8 moves slowly in the direction of the stationary plate 9 but accelerates in the opposite direction. In operating the apparatus and during the period when the shoot 8 moves slowly towards the plate 9, a " bridge " of material forms in the shoot but is cleared when the shoot moves back quickly. The roller 16 deposits material from the shoot on to the conveyer 18 where the material is loosened and trimmed by two banks of forks 29 which are actuated by crank-shafts 25. If the material accumulates to more than a predetermined amount at the beginning of the Section 18A of the conveyer, pressure is exerted on a pivoted plate 23 and the drive to the roller 16 and cams 14 is switched off until the accumulation is reduced by continued operation of the conveyer 18. The distance between the points of the forks 29 and the Section 18a of the conveyer is adjustable by movement of the bearings of the crank-shafts 25 and by screw means 32, 33 for vertically adjusting the framework 31 supporting the conveyer. A variable speed gear may be provided for the conveyer.

Title: Improvements relating to apparatus for drying materials by heat radiation
IPC: F26B5/04
Filed: 1950-12-18
Abstract: 696,655. Drying apparatus. FARBENFABRIKEN BAYER. Dec. 18, 1950 [Dec. 16, 1949; Sept. 11, 1950 ; Sept. 26, 1950], No. 30812/50. Class 34 (ii) [Also in Group XI] Apparatus for the drying in vacuo of material distributed.on a moving belt 1 has a number of heated tubes 15 positioned above and parallel to the belt with burners 17 at inlets of the tube, and means for withdrawing combustion gases from the tube outlets. Wet material is fed from a container 3 through a pipe 4 and emerges through a slit 6 on to the belt 1 the rate of flow depending on the speed of the belt and the thickness of the layer depending on the pressure against the slit 6. A counter pressure roll 8 beneath the belt is operated by springs or by a piston 10 under liquid pressure and if the paste in the pipe 4 becomes more liquid its pressure increases at slit 6 and operates on a membrane 11 to close a steam pipe 12 and increase the pressure on the liquid beneath the piston 10 and prevent extra material emerging from the slit 6. The combustion gases of the gas-burners 7 are removed from the tubes 15 by an exhauster 18 on the outlet side. Temperature control devices such as resistance thermometers 19 are shielded from radiation and indicate the temperature by devices 20. When adjustable limits 21 are exceeded, current supplied to coil 22 retracts an armature 23 to tilt switch 24 and close the circuit of a heating apparatus 25 and cause a rise of liquid in the arm of the U-tube 26 to close the supply of fuel from pipe 27 to burner 17 and extinguish its flame. Cool air is then sucked through pipes 15 by the exhauster 18. When the temperature drops again the gas supply to the burners is resumed and the gas is lighted by pilot flame 28 and pipe 15 reheated. Thus heating and cooling alternate with each other. Each pipe 15 has its own burner 1 control devices. Dried material falls into a collector 31. To prevent rising steam from causing an insulating layer between the material and radiating pipes the vapours are sucked off from the chamber and returned via pipe 34 after partial condensation in a condenser 33, condensate being discharged by a pump 35. To keep the rate of heating in step with the velocity of the belt 1 a Rootes blower 65 is arranged in the fuel supply pipe 27 and is coupled to the driving wheel of the belt 1. In a modification (Fig. 1A) a chamber 2<SP>1</SP> contains a belt 1<SP>1</SP> and has a pipe 3<SP>1</SP> for evacuation of gases. The material to be dried is pumped from a container 4<SP>1</SP> into tank 7<SP>1</SP> through which the belt passes and combustion gases heat radiating tubes 11<SP>1</SP>. Temperature control devices 15<SP>1</SP> protected by a screen 20<SP>1</SP> control the supply of fuel to the burners 13<SP>1</SP> through switches 16<SP>1</SP>. Dried material falls into container 22<SP>1</SP>.
