Title: Improvements relating to the manufacture of fuel briquettes
IPC: C10L5/10
Filed: 1932-02-23
Abstract: 402,139. Agglomerating fuel. ROBERTS, A., 236, South Coronado, Los Angeles, U.S.A. Feb. 23, 1932, No. 4081/33. Divided on 402,107. [Class 50.] An organic binder such as pitch and an inorganic binder of the nature of cement are distributed throughout a pulverulent fuel mass by water or an aqueous solution or suspension, 1“ times the weight of the binder when the fuel is fine enough to pass a screen of 30 meshes per linear in. and increasing in proportion as the fineness increases. The moulded briquettes are baked e.g. at 1000‹F for 30-90 minutes to render them smokeless. The fuel particles are of a size capable of passing a screen selected between 25-100 mesh and the inorganic and organic binders comprise in general not more than 5 and 7 per cent respectively of the total mass. A small quantity of sodium or potassium chloride, boric acid, borax or ferric oxide and flame colouring salts such as of strontium may be added, the fuel cement and organic binder being preferably mixed and the salt dissolved in the water and then worked into the mixture. The mass is suitably pressed at 2,000-10,000 lb. per sq. in. whilst at about 100‹-120‹ F, the preceding mixing being effected at about 180-250‹ F or not exceeding 400‹ F if the fuel itself includes organic binding material. Oxidizing agents or ignition accelerators such as copper or ferric oxide or boric acid may be applied to the briquette surfaces. The fuel material may comprise coal, coke, petroleum coke, lignite, peat, sawdust and spent tan bark. In an example a mixture of 81.5 parts of coke of 30 mesh with 1 part of cement, 7 parts of asphalt, .5 parts of sodium chloride and 10 parts of water is briquetted at 3000- 7000 lb. per sq. in. Specification 402,107 is referred to.

Title: Improvements in and relating to supercharged compression ignition internal combustion engines
IPC: F02D23/00
Filed: 1950-02-18
Abstract: 692,198. Change-speed control. LEYLAND MOTORS, Ltd., and MUELLER, A. Feb. 19, 1951 [Feb. 18, 1950], No, 4229/50. Class 80 (ii). [Also in Groups XXVI and XXVII] In a compression-ignition engine having a supercharger driven from the engine through variable speed gearing and a suction governor for varying the fuel supply, the fuel control means is interconnected with the variable speed gearing so that the supercharger gear ratio is increased when the fuel supply is increased beyond a predetermined value, the increase of fuel supply and supercharger speed being prevented when a predetermined engine speed is exceeded. The fuel supply is controlled by a governor 4 actuated by intake pipe suction, e.g. as described in Specification 575,146, [Group XXVIII], or 653,586, [Croup XXVI], and depression of the throttle valve control member 12 past full-throttle position under high load, low speed conditions causes opening of a valve 14 by a member 17, which opens the fuel governor suction pipe 5 to atmosphere to increase the fuel supply, and causes closing of a switch 8 by a member 10 to energise an electromagnet 3 to cause engagement of the high-speed gear of the supercharger; the throttle valve 6 remains in the full open position due to a lost-motion connection in the operating linkage. Closing of the switch 8 also energizes a solenoid 18 to withdraw a spring-loaded armature 19 holding the valve 14 closed. When the engine speed rises to a predetermined value, a centrifugal governor 13 opens a switch 9 which causes re-engagement of the supercharger low-speed gear and deenergization of solenoid 18 to allow the armature 19 to close the valve 14 irrespective of the position of the valve-actuating member 17. The two-speed supercharger drive may be that forming the subject-matter of Specification 685,841., the higher gear being engaged by a hydraulic servomotor the valves of which are actuated by the electromagnet 3. The supercharger may have a by-pass valve as described in Specification 688,899, [Group XXVII].

Abstract: 1,214,168. Selective signalling. GIDDINGS & LEWIS Inc. 30 Jan., 1968 [27 Feb., 1967], No. 4616/68. Heading G4H. In a position digitizing system gear coupled resolvers 31a, 31b, 31c, 31d, Fig. 2a, each produce a phase significant signal which is squared, 61a, 61b, 61c, 61d, Fig. 2b, and used to gate 55a, 55b, 55c, 55d, the contents of a sweep generator counter 35 into fine, medium-fine, medium coarse, and coarse registers 53a, 53b, 53c, 53d. A similar group of resolvers is provided for each of three co-ordinate axes and the gating and registering circuits are time-shared. The registers 53a, 53b, 53c, 53d are arranged so that the highest denominational digit in any one is of the same denominational significance as the lowest denominational digit of the next. They are read out sequentially, lowest order digit first, into a compositor 83, which assumes that the contents of the fine register are correct and progressively modifies the higher order digits so as to produce a composite number indicating the desired position. An example of how the compositor functions is shown in Fig. 5a, in which a mediumfine (MF) reading of 88 has to be increased to 90 to bring its lowest significant digit into agreement with the highest significant fine digit, a medium coarse (MC) reading of 10 has to be reduced to 09, and a coarse (C) reading of 89 has to be increased to 90. Correction of any reading is effected in principle by stepping it either forwards or backwards so that its lowest digit assumes the required value after the least number of steps. Thus each reading has a tolerance of 4. The actual calculation, however, is effected by a complicated sequence of subtractions, additions and shifts using a sevenstage full-adder (201) and a shiftable accumulating register (205) (Fig. 4c, not shown) and, for the numbers given in Fig. 5a, is summarized in Table I. Two-phase resolvers 27a, Fig. 46, are energized by 500 c/s. sine and cosine waves obtained from a 2 Mc/s. clock. The clock also steps a binary coded decimal counter A, B, C, 102, at a frequency of 500 kc/s. so that each cycle of the resolver energizing potential is divided into 1,000. The phase significant output from the resolver rotor is squared, 57a, and its leading edge is reclocked, 71a, so that the contents of the counter ABC are gated into registers 53a at time when the count is steady. The counter ABC, together with a further decade D and binary-to-decimal converters 141, 143, 145 also produces control signals which cause operations to occur in the correct order. Thus, one complete cycle of operation of the system comprises 1000 programme times. From time 001 to time 120 the output of the x-axis resolvers is examined-see gate 63a, Fig. 46. Actually 100 programmes times corresponds to one cycle of the resolver energizing potentials, but since the rotor may be moving when its output is examined 120 programme times are allowed because the frequency of the resolver output may fall below 500 c/s.

Title: Improvements relating to the production of single crystal layers
Inventor: HEATH EDWARD GEORGE
IPC: H01L21/205
Filed: 1961-02-08
Abstract: A single crystal layer of silicon is produced on a silicon substrate by means of the reversible reaction Si (solid) +SiX4 (vapour) = 2 SiX2 (vapour) where X is a halogen, which includes the steps of placing the silicon substrate in a first temperature controlled region, placing a quantity of silicon to be deposited on said substrate in a second substantially independently temperature-controlled region which communicates with said first region, raising the temperature of said first region to a predetermined temperature passing a vapour of a silicon tetrahalide therethrough, said temperature and said vapour being so chosen as to cleanse the surface of said silicon substrate, and subsequently regulating the relative temperatures of said first and second region so that the temperature of the latter region becomes greater than that of the former so that deposition of said elemental silicon occurs on said substrate. In an example the tetrahalide is SiCl4 and the first region is heated to 1300 DEG  C. and the second to 1100 DEG C. to cleanse the substrate.  The temperatures are then adjusted to 1100 DEG  C. and 1300 DEG  C., respectively, for the deposition of silicon.  Reference has been directed by the Comptroller to Specification 754,554.
