Title: Troughed belt conveyor
IPC: B65G39/16
Filed: 1960-05-04
Abstract: 926,815. Froughing idlers for belt conveyers. UNITED STATES STEEL CORPORATION. May 4, 1960 [May 28, 1959], No. 15808/60. Addition to 863,074. Class 78 (1). The belt conveyer of the parent Specification is modified in that the inner and outer wing rollers 36, 38 of each of at least some of the troughing roller assemblies are flexibly connected to each other and to the central roller 30 so that the adjacent ends of the axes of the rollers 36, 38 are swingable by the engaging belt in either direction of belt movement and in a plane parallel to the path of the belt. The flexible connections consist of pivot-pins 54, 62 interconnecting the shafts 32, 40, 42 of the various rollers. By this means, and by making the rollers 38 longer than the rollers 36, the directions in which the wing roller axes extend towards or away from the direction of approach of the belt are reversed automatically when the direction of movement of the belt is reversed, so maintaining self-centring action on the belt in both directions of movement of the belt. In each direction of belt movement the directions in which the wing roller axes extend in relation to the direction of approach of the belt are opposite to those in the case of the troughing roller assemblies constructed as described in the parent Specification. In order to mount the modified roller assemblies there is provided on each side of the centre roller a support 4 on which a bearing 34 for the shaft 32 of the centre roller is carried and to which the shaft 40 is pivoted by the pin 54. Cooperating bifurcated and flattened adjacent ends 46, 60 of the shafts 40, 42 are pivotally connected by the pin 62, and a bracket 64 is carried by outer pedestal 2 which is provided with an aperture receiving the outer end 66 of the shaft 42 for limited pivotal movement and for axial sliding movement therein, the aperture and the end 66 being non-circular. A cover-plate 70 limits upward movement of the shaft end 66. A pin 76 interconnects the rollers 36, 38 to cause them to rotate together. Specifications 709,908 and 735,561 also are referred to.

Abstract: 757,330. Spray burners. RUDLING, F. J. June 9, 1954 [June 9, 1953], No. 15854/53. Class 75(1). In a liquid fuel burner, means are provided for forming a mixture of fuel and air and supplying such mixture to a main jet formed by an annular opening G<SP>1</SP> between a cylindrical central core D<SP>1</SP> and a hole in a nose cap F' detachably secured to the body, the outer surface F4 of the nose cap forming the inner surface of an opening G<SP>2</SP> forming a second jet to which air only is supplied. The air opening G<SP>2</SP> is of annular conical form and surrounds the main jet G<SP>1</SP>, its outer surface being formed by a conical internal surface E<SP>3</SP> on an end cap E adjustably screwed on to a front burner part B adjustably screwed on to a rear burner part A. Air is delivered by a passage A<SP>1</SP> in the rear part A to a conical passage G between a conical surface on the front part B and a conical surface on a fuel jet C carried by the rear part A and the mixture of air and fuel passes into a cylindrical passage B3 in the front part B where it is given a rotary motion by inclined grooves D<SP>3</SP> in a block D<SP>2</SP> secured to the end of the central core D<SP>1</SP>. Air is also delivered by four passages I in the front part B to a chamber H in the end cap E communicating with the air jet G<SP>2</SP> through oblique grooves F<SP>6</SP> in a flange F<SP>5</SP> on the nose cap F, the grooves causing the air to rotate in a direction opposite to that of the fuel air mixture.

Title: Improvements in and relating to fuel injection engines having reversing and lead controlling mechanism
IPC: F01L13/00
Filed: 1947-06-17
Abstract: 634,738. Fluid-pressure servomotor-control systems. NORDBERG MANUFACTURING CO. June 17, 1947, No. 15946. Convention date, May 23, 1941. [Class 135] [Also in Group XXVII] The timing of the fuel injection of a reversible fuel-injection engine (see Group XXVII) in either direction of rotation is effected through a speed responsive governor 43. An arm 47, which moves in relation to engine speed, is connected by a follow-up linkage to a servomotor piston 41 and to a piston-type distributorvalve 48, with end admission and central exhaust for controlling the supply and exhaust of pressure liquid to and from the working spaces at the ends of a cylinder 42. The movement of piston 41 and attached rack 39 causes rotation of a shiftable element 23, and hence a fuel-pump camshaft attached thereto, so adjusting the timing of the fuel pump in accordance with speed.

Title: Improvements in the wings and similar members of aircraft
IPC: B64C9/22
Filed: 1920-06-16
Abstract: 166,430. Page, F. H., and Page, Ltd., H. June 16, 1920. Planes and the like, construction and arrangement of; steering, balancing, and regulating altitude.-In a plane in which an auxiliary wing section 7 is adapted to be moved to or from the front edge of the main section 1 to close or open a slot extending transversely of the line of flight, as described in Specification 157,567, the pivots 3, 5 which connect the parallel arms 2 to the main section 1 and the auxiliary wing 7 respectively are arranged at an angle to one another, and the pivots 5 support the auxiliary wing 7 through bolts 6 which can turn about their axes within the auxiliary wing. This construction causes the angle between the chord of the main wing and the chord of the auxiliary wing to be reduced as the auxiliary wing is closed on to the main wing, and enables the auxiliary wing to fit snugly upon the main wing when the slot is closed, while providing a wider opening on the under surface of the plane than on the upper surface when the slot is open. The pivots 3 on the upper and lower planes of a biplane may be formed as a continuous vertical shaft which can be operated by the aviator through bevel gearing.

Abstract: 476,810. Impulse transmitters. CSARADA, H. DE. June 15, 1936, No. 16661. [Class 40 (iv)] In an impulse sender designed to send any one of a number of multi-digit numbers in response to a single setting operation, a continuously operating interrupter being shortcircuited at suitable times in accordance with the shape of a selected control member, the control members, in addition to being readily interchangeable, are normally stationary, only that corresponding to the selected number being moved at one time. As shown, the control members are in the form of notched quadrants 13 which are secured to pivoted levers 9 by a pin-and-slot arrangement and a spring clip. To send a number, one of the levers 9 is moved to the horizontal position. In its movement it engages a common transverse bar 5 which controls off-normal springs for shunting the telephone instruments and the interrupter and winds up the clockwork mechanism. On release of the lever, the clockwork drives the interrupter springs under control of a flier, the vanes of which can be bent to adjust the speed, and the bar 5 restores the lever 9 and with it the quadrant 13, the notches in which cause springs 12, 14 to short-circuit the interrupter at suitable times. The subscriber may have a tool, Fig. 10, for notching quadrants himself, the hole of the flank being threaded on a stud 24. Correct positioning of the notches is facilitated by a pointer 25 and, if desired, a scale on the die member 27.

Patent GB-967095-A (GB)
Title: Method of treating paper for photographic supports
IPC: G03C1/775
Filed: 1962-05-03
Abstract: A hydrophilic photographic paper support is made by coating a paper support with a chromium halide complex of a long-chain fatty acid, drying it and bombarding the coated surface with electrons until the water contact angle is less than 73 degrees.  The water contact angle is determined by placing a drop of distilled water on the level sample, and projecting an image of the drop and sample on to a screen.  The angle between the unwetted surface of the sample and a tangent to the drop image at the point where the edge of the drop touches the sample is measured and is the water contact angle.  The support may be treated by dip-coating or tub-sizing with the chromium halide complex dissolved in a mixture of alcohol and water and then heated to dry it and may also be calendered before bombardment.  The paper may be of partially acetylated fibres.  The sizing compound may also contain urea and sodium formate.  The coated paper may be further coated with a light-sensitive silver halide emulsion. Specification 937,494 is referred to.
