Patent GB-193754-A (GB)
Abstract: 193,754. Hounsfield, L. H. May 9, 1922. Fuel containers.-Where a reserve supply of fuel is provided for by taking the fuel from the tank by a stand pipe extending to some distance from the bottom thereof, it is found that as the level of the fuel approaches the top of the pipe the fuel flow and the working of the engine become irregular. This is obviated by making the stand pipe in the form of a siphon which, as the fuel level falls becomes " broken," whereby the fuel flow is cut off suddenly, thus drawing attention to the fact that only the reserve supply remains. The siphon may be broken by providing near the top a small hole about one-hundredth of an inch diameter. This, however, being difficult to drill, it is preferred to replace it by a larger hole covered with gauze or by a gauze, tube forming the whole of one limb of the siphon, the holes being of such dimensions that the fuel film over them is sufficiently strong to admit of such a vacuum as will ensure the siphon being definitely " broken " once the film has given way. The stand pipe SP and the reserve pipe R are fitted to a casting CV which contains the control cock P and is attached to a boss B on the underside, of the tank T. The stand pipe is converted into a siphon by soldering thereto a cap C from which a tubular piece of gauze extends downwardly through the hole H and is flanged to make a joint with the flange F. A vent pipe W extends upwardly from a chamber V which holds a supply of fuel for starting. The cock P is actuated through a rod D provided with cross pins to engage the cock and a key K. A pin I projecting through the wall of the casting, engages notches in a collar L to hold the cock in definite positions. Stops S, Fig. 6, separated bv a wide angle determine the " on " and " reserve " positions of the cock. The cook P, which is suitably grooved, may place the carburettor float chamber in communication with the main supply conduit A, the reserve conduit X or the starting chamber V. Specification 199,231, [Class 7 (iii), Internalcombustion engines, Carburetting-apparatus &c. for] is referred to.

Abstract: 244,367. Zeumer, H. Aug. 5, 1925. Locks, permutation, of the kind in which notched rings are separately set to allow a spring-pressed locking-member to release the part locked, are provided with locking rings of a polygonal crosssection with spring-pressed balls mounted in their side faces to hold them in adjusted position. The balls click over recesses preferably on separating washers so that the click produced by the notch in passing the locking-member is masked, preventing picking. The locking-member r is U- shaped and engages recesses in links e and k of the members to be locked. It is held in locking engagement against the spring i by polygonal rings m each of which has a ball t pressed outwards by a spring q into engagement with a separating washer s. When recesses o in the rings are all aligned with the member r the spring i forces it upwards and releases the member k. The washers s have recesses w over which the balls click, the recesses being equal in number to the faces of the rings m. The washers s may be dispensed with, in which case the balls engage the adjacent ring.

Filed: 1918-11-29
Abstract: 140,851. Kirke, P. St. G. Nov. 29, 1918 Generating by indirect contact of hot waste gases.-A multitubular horizontal or waste-heat boiler for use with industrial furnaces is provided with mechanical means for inducing a draught such that the gases travel through the tubes at a mean velocity of not less than 40 ft. per sec., efficiency being attained by making the length of the tubes not less than 50 times their internal diameter, or by inserting a superheater at the entrance to the tubes, or by both expedients. Waste gases are drawn through a boiler h by a fan c, and are delivered into the chimney i through a flue k. A damper-controlled by-pass l allows the gases to pass into the chimney when the fan is out of use. When the boiler is not working, a damper m in the waste-gas flues is closed and a damper n opened, thus allowing the gases to pass directly into the chimney. A superheater g may be placed in the chamber a at the entrance to the tubes. The gases may pass through return tubes or through tubes in a second boiler shell. A superheater may be fitted in the space between the two sets of tubes. The part of the front plate not cooled by water may be protected from burning by an auxiliary plate.

Abstract: 729,274. Digital electric calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 17, 1953 [July 21, 1952], No. 19870/53. Class 106 (1). An electronic counter comprises a plurality of groups of cascade-connected trigger elements, means supplying input pulses to one of the groups, and a coincidence circuit controlled by the trigger elements of a first group whereby an actuating pulse applied to one of the elements of the first group is transmitted by the coincidence circuit to a second group prior to completion of the cascade operation of the elements of the first group. Pulses from a source S are fed to the first stage 20 of a chain of hard-valve trigger circuits, each of which has a connection to a cathode-follower output device 32-43, a connection 20a &c. to the next higher trigger in the chain (via a cathodefollower in some cases), a connection from an input gate 46-57, and a connection to a circuit R for supplying a positive resetting pulse. The cathode-followers 32-43 provide output signals in parallel form representing the binary number stored in the counter. In addition, the first group of cathode-followers 32-37 are connected to an " AND " gate 44 which causes a positive output from a cathode follower 45 when the trigger elements 20-25 are all in the " ON " condition (representing a count of 63). This positive voltage does not affect the trigger 26, but the negative-going change which occurs when the next (64th) input pulse is counted causes a non-coincidence in the gate 44 which triggers the circuit 26 of the second group 26-31 before the carry-over " ripple " reaches the last element 25 of the first group of triggers. Other groupings and arrangements of coincidence circuits to reduce the number of " ripples " during carry-over are also described. The " AND circuits 46-57 provide for a parallel entry into the counter of binary data when a so-called " dumping " pulse is supplied by a circuit D.

Abstract: 1,059,487. Photographic copying apparatus. DAINIPPON INK & CHEMICALS Inc. May 13, 1964 May 18, 1963], No.19874/64. Heading G2A. In copying an original disposed on one cylinder on to a second cylinder having a photo-sensitized surface, the two cylinders are mounted in parallel spaced-apart relationship and rotated in opposite directions; a light source and optical system are moved along axially between the cylinders so that the light, falling on the original cylinder, scans it in a helical path, and the reflected beam passes through the optical system to trace a corresponding helix on the copy cylinder. Cylinder 1 may have the original pattern or sheet secured round it, and the copy cylinder may be treated with a photo-sensitive material. The two cylinders are mounted parallel to each other, and rotated in opposite directions by synchronous motors 8, 9 respectively. A light source 13 and optical system 11 are disposed between the cylinders, and can move parallel to them along a lead screw 14 driven by a motor 15. The optical system comprises a roof prism 5 and a series of lenses 3, 4, 6, so that light reflected from the part of cylinder 1 illuminated by the source passes through the optical system and falls as a reversed image on copy cylinder 2. As the cylinders rotate, and the optical system and light source progress along the lead screw, the light falling on cylinder 1 scans it in a helical path, and similarly the image falling on cylinder 2 also traces a helical path. Cylinder 2 may be of greater diameter than cylinder 1, if a magnified image is required.
