Title: Improvements in or relating to the manufacture of brick
IPC: B28B13/02
Filed: 1950-10-30
Abstract: 705,377. Brick-moulding machines. MORGAN CRUCIBLE CO.. Ltd. Oct. 30, 1950 [Feb. 7, 1950], No. 26403/50. Class 87 (2) Brick-moulding machines of the type, Fig. 1, including a hopper, a mould cavity, die means to form a brick in the mould cavity and to eject the formed brick therefrom and a reciprocating charger, which on its forward stroke puts a body of coarse mix into the mould cavity and removes a brick which has been ejected therefrom and on its return stroke removes excess mix from the surface of the charge, are modified by the addition, Fig. 2, of a trough 55 which contains a supply of fine mix and an element 60, moving over the mould cavity, which receives fine .mix from the trough and spreads it on the coarse mix in the mould cavity. The object is to eliminate' variation in the surface of moulded bricks resulting from an uneven surface of the coarse mix in the mould cavity and consequent non-uniform distribution of the mix when the die presses on the uneven surface. The charger 20, shown in Fig. 2 in its extreme forward position when it has discharged coarse mix 53 into the mould cavity 25, carries on its forward end a cross-bar 45 of angle section whose depending flange 46 meets a stud 51. The flange 46 also pushes away the previously moulded and ejected brick. The stud 51 is threaded through a bracket 48 on a gate 49 which controls the opening at the bottom of the trough 55. A spring 47 holds the gate 49 in closed position except when pushed forward by the flange 46 acting on the stud 51. The width of the opening may be adjusted by screwing the stud 51 in or out. The charger 20 also carries, as is general, a raising gate 40 (used to pile coarse mix where needed during the manufacture of special shaped bricks) and on the cross-bar 41 of this raising gate is the spreader 60: i.e.' a small hopper with a long, narrow slot for its bottom. opening. This spreader is beneath the trough 55 when the gate 49 is opened and receives a charge of fine mix (a hole 44 allowing the material to pass through the horizontal flange of the cross-bar 45) and on the return stroke of the charger 20 the fine mix is " flowed " by the spreader 60 over the surface of the coarse mix in the mould cavity to give an even level by scraping action of the edge of the discharge slot of the spreader. The spreader 60 and gate 49 could be operated by other means than the reciprocating charger provided they spread fine mix evenly over the'coarse mix in the mould cavity. A handwheel 34, lever 59 and spring'56 provide a pressure-adjusting mechanism.

Title: Improvements in or relating to travelling wave linear particle accelerators
Inventor: GALLOP JOHN WINSTON
IPC: H05H9/02
Filed: 1952-10-21
Abstract: 737,098. Particle accelerators. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 21, 1953 [Oct..21, 1952], No. 26459/52. Class 39 (1). A travelling wave linear particle accelerator comprises a slow wave structure disposed about a curvilinear axis, and a transverse magnetic field having a transverse gradient is applied throughout the operative length of the structure. The transverse gradient is such that the particles are constrained to travel in a focusing region of the electric accelerating field. The slow wave structure 5, which may be a waveguide, or as shown, a coaxial line having a helical inner conductor of progressively increasing pitch, is bent so that its axis forms a spiral. The magnet 6 is C-shaped in crosssection and extends continuously along the spiral line. The limbs of the magnet form the pole-pieces. The faces of these pole-pieces are shaped to set up the required field gradient. The magnet is excited by water-cooled conductors located within the recesses of the C- shaped magnet. The vacuum maintaining system includes a pump 19, a duct 20 lying below and parallel to a radius of the spiral line, and pipes 21 leading to the convolutions of the line. The particles to be accelerated are derived from a primary accelerator, e.g. a Van de Graeff machine, and are deflected by a magnet 16 into the input end of the spiral line.

Filed: 1966-06-14
Abstract: 1,095,377. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 14, 1966 [June 30, 1965], No. 26471/66. Heading G4A. In a data processing system, the final destination of data called for from one of four memory units 12, 14, 16, 18 is determined at memory access time by a control matrix 50 which enables one of four gates 82, 84, 86, 88 to route the data to registers E B , E c , E D  or to input/output devices I/0. Each instruction word enters a register I A , but when a corresponding data word is called for, the central processing unit 40 requires five operating cycles to produce a corresponding data word at the memory output. During this time the instruction word may move down through a stack of three further registers I B , I c,  I D  as these became available, these registers corresponding respectively to the data registers E B , E c , E D . To compensate for this, while data is being retrieved from memory, the the matrix 50 receives signals indicative of the position of the instruction word in the I registers and at access time, routes the data to the E register corresponding the I-register containing the instruction word. The matrix 50 consists of a number of sections each split into stages representing cycle times of the central processor, each stage consisting mainly of an AND gate and a shift cell, signals entering the matrix being sequentially moved through each stage by timing signals from a clock pulse generator (not shown). The first four sections 50-62 receive signals governing the selection of one of the four memory units, and while the chosen memory is cycling, the matrix issues an inhibit signal to prevent further requests for words from this memory. The matrix sections 90, 92 control routing of an instruction word from memory to the I-registers while sections 94, 96, 98 control the routing of data words to E-registers E B , E c , E D  respectively, further AND gates together with inverters being incorporated in these sections, Fig. 3 (not shown) which enable the transfer of register control from one section to another. The remaining section 100 enables data to be routed via gate 88 to input/output devices.

IPC: G01S15/42
Filed: 1965-06-23
Abstract: 1,156,323. Echo sounding. SMITHS INDUSTRIES Ltd. 23 Sept., 1966 [23 June, 1965], No. 26511/65. Heading H4D. In a sonar system, echoes received from different ones of a plurality of discrete directions unequally spaced throughout a predetermined sector are displayed in sequence during respective successive ones of a regular sequence of periods. For locating fish on or near the bottom FD of the water or charting a non-conformal plan of the bottom an acoustic pulse is transmitted simultaneously in seventy directions, lying within a sector whose plane is vertical and whose axis is downwardly inclined from horizontal, by means of an array of seventy respective transmitting/receiving transducers located at the focal surface of an acoustic reflector and coupled to transmitting/receiving circuitry. The directions are chosen such that equal slant-range increments occur between adjacent pulse paths SA, SB, SC, SD from a ship S, carrying the sonar, to the bottom; echoes received by the respective transducers then occur in a regular sequence and are displayed on an electrochemical recorder. The recorder (Figs. 2 and 3) comprises a stylus (28) moved. over a chart (22) by a belt (19). The belt drive drum (18) carries a brush (20) which is connected to the stylus and scans, during one traverse of the stylus over the chart, seventy commutatorcontacts (16) to which are applied the echo signals from the seventy directions respectively. The acoustic pulse transmission is triggered in synchronism with the recorder operation, and the depth range from which echoes are recorded may be selected by adjusting this synchronization or employing additional brushes which scan commutator-contacts (16) adjacent whichever contact is in engagement with brush (20) at any instant. Compensation for pitch (for a forward-looking sonar) or roll (for a side-looking sonar) of the ship may be achieved, to a first order, by adjusting the angular position of the contacts (16) relative to the brush (20) or brushes.
