Title: Improvements in or relating to indicators for the level of liquids
IPC: G01F23/16
Filed: 1922-09-05
Abstract: 204,501. Chamberlain, W. A. Sept. 5, 1922. Indicators actuated by pressure of head of liquid.-An open-ended pipe 1 has one end in communication with the reservoir 3, for the liquid the level of which is to be determined and the other end extends to the top of an inverted vessel 15. An indicator-tube 8 is arranged concentric with the inverted vessel and in communication with its lower end. The inverted vessel and indicator tube are partly filled with liquid. A rise in the level of the liquid in the reservoir causes liquid to rise in the pipe 1 and air to be forced into the inverted vessel. A quantity of liquid proportional to the rise in the reservoir is thus displaced from the vessel into the indicator tube.

Abstract: 819,743. Boxes. WILLMOTTS Ltd. July 23, 1957 [Aug. 4, 1956], No. 24103/56. Class 18. A box comprises two hinged together portions e.g. lid 10 and body 11 having at least one pair of side walls 14, 17 transverse to the hinge axis non-parallel when the box is closed, so that parts of the side walls are brought progressively into frictional engagement during the closing of the box. The adjacent surfaces of the side walls 14, 17 may be of curved configuration frictionally inter-engaging remote from the hinge axis, whereas a clearance 21 exists between the portions of side walls adjacent the hinge axis. An additional frictional fastening may be constituted by arranging the front wall 15 of the lid portion to engage the front edges of the side walls 17, the front walls 16 of the body being of somewhat reduced depth which also limits the closing movement. The lid and body blanks may be laid on a piece of flexible material with the two rear walls adjacent and secured to the material by pressure and heat. The walls of the lid and body portions are then formed by a pressing operation and an interior layer of flexible material applied. Lid 10 and body 11 are now connected together by two thicknesses 18, 19 of flexible material which forms the hinge 20 of the box. The blanks may be formed from sheet steel and an internal fitting, with shaped recesses for articles, may be provided and may assist in stiflening the box ; the lining 18 may not completely cover the interior.

Abstract: 1,219,828. Printing apparatus. CHAMBON Ltd. 21 May, 1968 [22 May, 1967; 13 Dec., 1967], No. 24168/68. Heading B6C. Dampening fluid, such as water, is transferred from trough 1 to a roller 18, and eventually to lithographic printing cylinder 37, by a roller 2, which has an hydrophilic surface and is wiped by a flexible-surfaced roller 7, which is held so that it does not rotate after being contacted by the wetted surface of the roller 2. The roller 2 may have a chromium surface and the roller 7 one of rubber, and the roller 7 may be friction-braked, and be rotated by the roller 2 only until dampening fluid lubricates their contact so that the roller 2 slips against it. The roller 2 may be wiped to a greater or lesser degree by the roller 7 by adjustment of the pressure with which the roller 7 is urged against it. The roller 18, which is flexible-surfaced, may revolve at a constant speed and slip against the roller 2, so that the quantity of water delivered to it can be varied by changing the speed of the roller 2. Alternatively the roller 18 may revolve at a varying speed and drive the roller 2 by contact, slipping only when its speed falls so low that a constant-speed drive operating through a free-wheel device or an electrical equivalent of one takes over to drive the roller 2. The roller 2 may deliver dampening fluid to an inking roller, or to a train of inking rollers 28, 29, 31-36, 38, 39, 41-44, receiving ink from a duct roller 26 and messenger roller 27 and supplying it to a printing cylinder 37. The rollers 33, 34 and 39 of the train are reciprocated axially. The printing cylinder 37 may be replaced by one of a different size and the inking rollers 36 and 44 be moved relative to the rollers 33 and 43 to accommodate it.

Headings B3A, B3P, B3R and B3V. [Also in Division B1] A transition piece for use in bonding dissimilar materials, e.g. metals, cements or ceramics, is made by a method involving the melting down by an arc or electron beam of a rod of variable composition. The transition piece has a coefficient of expansion which changes along its length in a manner which in a graph is shown by a line of S-shape. The rod may be made by mixing powder alloys A and B, Fig. 5, or their powdered constituents fed from hoppers 1 and 2 under the control of valves 5, 6 regulated by a moving cam 10 to produce a mixture in a container 13 varied in a manner to produce a number of transition pieces. The powder in the container 13 is in a rubber tube 12 which is subjected to hydrostatic pressure to produce a compact which is vacuum sintered. The sintered rod is used as an electrode and melted in a vacuum arc furnace to produce an ingot. The melting may bo repeated and the subsequent ingot is extruded, forged or rolled to produce a transition piece in the form of a tube, rod or sheet. In a modification, the rod to be melted is produced from a series of discs of varying composition or from two members of the alloys A and B jouned together and shaped as shown in Fig. 9. Numerous compositions are specified.

[Also in Division F1] As shown in Figs. 2 and 3 the spark advance and distributer unit 40 comprises a tubular sleeve 42 mounted on the crank-shaft 20 for rotation in unison therewith. A radial flange 44 is pressed on to the sleeve 42 and constitutes a circular laminated disc made of non-conductive material. Alternatively the flange and the disc may be suitably moulded in one piece using an insulating plastic. Sandwiched between laminations of the disc 44 is a bridging conductor 46 comprised of resilient conductive spring wire or the like which includes two circumferentially spaced partly enlarged radial end portions 46a, 46b which protrude slightly beyond the disc 44. The bridging conductor 46 serves as a conductive link between the generator cable 21 and the spark plug cable 23. In order to advance the closing of the firing circuit the rear radial end 46a of the bridging conductor is mechanically moved so as to provide earlier mechanical juxtaposition. When the disc 44 is rotated the weight 74 is urged by centrifugal force to move radially and the curvature of the slot causes the weight to move in such a direction that the radial portion 46a is deflected in the direction of rotation of the disc. In Fig. 2a the leading radial portion 46b<SP>1</SP> is arranged for deflection by means of the weight 74<SP>1</SP>. In Fig. 5 one end of the conductor 92 is wound around the pins in a spring-like manner. A weight 96 is fixedly secured to the spring 92. Other modifications are described (see also Division F1).
