Title: Improvements relating to triangulated frameworks and their application to the construction of military bridges and the like
IPC: E01D15/133
Filed: 1940-04-30
Abstract: 540,945. Bridges ; metal girders. INGLIS, C. E., and KRYN & LAHY (1928), Ltd. April 30, 1940, No. 7747. [Classes 20 (i) and 20 (ii)] A method of building a bridge of lattice construction consists in assembling one girder comprising upper and lower boom and interbracing members of tubular section, and launching it, and then assembling supplementary girders of similar construction, in sites alongside the positioned section and connecting them thereto The girders having the same general characteristics as those described in Specifications 22079/14 and 112184, [both in Class 20 (i)], are each built up of tubular members 10, 11, 27 joined together to form a warren girder by four-way sockets 3, Fig. 5, at their lower ends and six-way sockets 4, Fig. 8, at their upper ends, opposed lower sockets being bolted to transverse bearers 6 on which the floor of the bridge is supported. The main girder is launched and then the supplementary girders on each are built up in situ and in order to allow these supplementary girders to be attached to the bearers depending pivoted bolts 19 are provided on the lower socket members to coact with clamping straps 21 which bear against the under sides of the bearers as described and claimed in Specification 540,956. The upper and lower socket members are also provided with transversely disposed apertures 29 to receive through bolts 53, Fig. 12, provided with end nuts and intermediate conical sleeves 34 to engage and distance the socket members of adjacent girders and whereby the girders on each side are connected together. The upper two apertures of upper socket members may be used to connect further bracing members for a superposed girder where this is required for great spans, or may be used to receive depending bolts 44 from pedestals 42 which are adapted to carry upper cross bracing members between the girders on opposite sides of the bridge. The joint between a tube and a socket is shown in Fig. 10, in which an apertured member 15 is screwed to the end of a tubular member and enters an aperture of a socket to receive a crosspin, the joint being tightened by a screwed sleeve 12 adapted to bear on a bearing surface 14 provided around the exterior of each aperture in each socket. To provide inclined approaches for the bridge, the lower sockets are formed in two hinged portions 47, 48, Fig. 15, each portion provided with two connecting apertures. Adjacent tubular members in the main and supplementary girders are clamped together by clamps 39.

Abstract: 121,751. Shorrocks, H. Jan. 7, 1918. Kinematograph apparatus.- In a shutter the masking blade, or the flicker blades, or all the blades, are made up of strips of different coloured translucent material ; the shutter may also comprise coloured screens which may be arranged so that they can be turned behind the blades, or so that they can be turned into their operative position, while the shutter is in motion and when it is desired to change from colour projection to monochrome projection or vice-versa. As shown in Fig. 3, the shutter comprises an integral frame having a central part b and a rim a connected by radial arms. Two blades d, each comprising a metal frame of U-section containing red strips covered by green strips arranged transversely to them, are held in position by means of studs e and T-headed screws f passing through slots in the frames of the blades. Colour screens g in similar frames are similarly held in position. In n, modification, Fig. 6, two pairs of connected colour screens, 1, 3 and 2, 4 are pivotally arranged one on each side of the shutter. The screens are held in operative position by catches i which, when monochrome pictures are to be projected, are engaged by a stop in their path to release them and permit springs h to pull the screens behind the blades. The catches and springs may be arranged so that the colour screens are held in their operative position until the catches are engaged by the stop.

Filed: 1947-03-26
Abstract: 640,360. Rolling screw-threads; die-rolling. GROB, E. March 26, 1947, No. 8221. [Class 83 (iv)] A rolling-machine, more particularly for rolling screw-threads, with at least two axiallyadjustable rolls 1 and 4 rotating in the same direction and which are caused to approach each other during rolling, substantially at right angles to their axes by a mechanical drive, is characterized in that an elastic member is inserted in the said drive and is capable of transmitting only a predetermined maximum force. The movable roll 4 is displaceable in a direction at right angles to its shaft 5 by the rotation of an eccentric 25 acting through the medium of a compression spring 29 which may be prestressed by adjustment of a movable barrel cover 30 by means of a screwed spindle 36. The spring pressure, i.e. the maximum rolling pressure, may be indicated by a pointer and in modifications the elastic member may be a ring spring or a pneumatic or hydraulic buffer. The eccentricity of the disc 25 is dependent on the form of the screw-thread to be rolled and is somewhat larger than the thread depth in order to load the compression spring additionally towards the end of the rolling process. The pass is adjusted by a screwed spindle 27 and the roll 1 may be adjustable to a small extent about a vertical stud to allow of the rolling of conical work-pieces.

Abstract: 1,255,259. Carburetters. GURTNER S. A. Feb. 14, 1969 [Feb. 22, 1968], No.8251/69. Heading F1B A carburetter having an automatic enrichment device comprises a feed chamber 2, Fig. 1, having a maximum filling level corresponding to that of a float chamber 1, which communicates with a jet 7 and with the float chamber 1 by a conduit 5 including a valve 3 which is open when the engine is at rest and is closed when a predetermined engine operating condition is obtained. Operation: When the engine is stopped the valve 3 is open so that chamber 2 is filled to its maximum level. When the engine is started the crank-case pressure acting in the chamber 12 through the non-return valve 14 closes valve 3. The depression on jet 7 primes the enrichment circuit via conduits 5, 6 and the chamber is progressively emptied, the engine being hot enough to cease enrichment when the chamber 2 is empty. When the engine is again stopped the valve 3 is opened and chamber 2 is filled at a speed which ensures that engine is cold when the chamber is filled. A control air throttle 18<SP>1</SP> restricts the enrichment circuit in the idling position of the throttle. In a modification the valve 3 is replaced by an electromagnetic valve energized by an engine alternator. In further modifications the jet 7 is arranged upstream of the air throttle or is connected to an auxiliary air inlet of the main fuel circuit.
