Patent GB-407966-A (GB)
Abstract: 407,966. Fuel and ignition controls ; valve accessories. HOLMES, H., 22, Portland Street, BUCKLEY, A., 12, Nursery Street, Birkby, and GLEDHILL, F., 213, Bradford Road, all in Huddersfield. Sept. 27, 1932, No. 26790. [Class 7 (iii).] Joint control of the ignition circuit and carburetter fuel supply is effected by a Bowden wire D. The operating knob C is formed with a transverse lug which either engages a slot in the end of the switch casing B or, on withdrawal therefrom and rotation through a right angle, rests against the concave end of the casing. In the latter position the spring-pressed sleeve A ceases to engage the contact E which is connected to the earthing terminal of the magneto. Alternatively, for coil ignition the withdrawal of the sleeve may bring an annular contact into circuit-closing position. Withdrawal of the wire D also lifts the needle valve L against the action of a spring l<1>. Fuel then passes from the pipe n' into the outer fitting N and through openings k<2> to the carburettor inlet k. A fueltight joint for the stem l consists of two cork or other washers O each interposed between washers M. Between the inner washers a perforated tubular distance piece is filled with mercury forming a liquid seal.

Title: Drift indicator for use in the drilling of bore holes
IPC: E21B47/022
Filed: 1960-12-01
Abstract: 894,565. Borehole linometers. VARNEY ENGINEERING CORPORATION. Dec. 1, 1960 [March 11, 1960], No. 41403/60. Class 97(2). [Also in Group XXI] A tool for automatically causing on the cessation of pumping of drill mud through a drill string during the drilling of a borehole indications of any deviations of the borehole from the vertical. The body 11 of the tool is supported within a drill string 10 and has projecting from the upper end an outwardly spring-biased, headed plunger 24 which is pressed back into the body during normal flow of drill mud through the string. The plunger is connected through a control means to a pendulum 44. On mud flow ceasing the plunger advances out of the body to an extent inversely proportional to the amount of upward movement of the pendulum. The movement of the pendulum is a measure of the degree of deviation of the bore since it is limited by engagement of a shoulder 92 on the pendulum with a predetermined shoulder of a series of shoulders 111 extending further inwards the higher the shoulder is in the casing. The head of the plunger can thus move past a predetermined number of annular shoulders 22 formed within the drill string, the number depending on the extent of movement of the pendulum and thus the degree of deviation of the borehole. On the pumping of drill mud recommencing the plunger is forced back into the body 11 and as the head of the plunger passes a shoulder a pressure pulse is set up in the drill string, the number of such pulses as recorded at the surface of the borehole indicating the extent of the deviations. U.S.A. Specifications 2,329,732, 2,435,934 and 2,762,132 are referred to.

Title: Improvements in and relating to voltage regulators
IPC: H02J7/24
Filed: 1958-12-23
Abstract: 843,591. Transistor circuits. GENERAL MOTORS CORPORATION. Dec. 23, 1958 [Jan. 6, 1958; Aug. 22, 1958], No. 41461/58. Class 40(6). [Also in Groups XXXV and XXXVI] In a voltage regulator for a generator (see Group XXXV), a bi-stable pair of transistors with a common emitter resistor are switched according to whether the control voltage is above or below the break-down voltage of a Zener diode. A control transistor 42 and the paralleled power transistors 18, 20 form the pair and switch the current supplied to the generator field 12 in accordance with the voltage tapped off a potential divider 54. When the voltage is high enough for the Zener diode 49 to conduct, transistor 42 conducts and the transistors 18, 20 are cut-off by the emitter bias voltage obtained across a silicon diode 32. This voltage drop is substantially constant for a range of forward currents. The reduction in current through the common emitter resistor 34 makes the emitter of transistor 42 less negative and hence the transistor becomes more conductive. Transient feedback through capacitor also assists the switching action. When the Zener diode 49 ceased to conduct, transistor 42 cuts off and the transistors 18, 20 become fully conductive.

Charge material supplied through shoots 60 is fired by hot gases supplied from a combustion chamber 44 through a sleeve 43, part of said gases with the cooling air rising up the shaft being extracted through ducts 36a, 36b and 36c into an annular duct 33 formed between the shaft and a hood 31. The remainder of the hot gases ascends the shoots 60 to preheat the incoming material, being joined at 33b by the admixed combustion gases and cooling air from the duct 33. Dust collecting in duct 33 is fed by a line 38 through valves 39a and 39b to valve 22a. Air supplied through pipe 52 to an oil burner 57 is preheated in a jacket 50 surrounding the combustion chamber 44 and a flue 62 terminates in a jacket 61 surrounding the hood 31.

Abstract: 1447225 Grinding crank-shafts LANDIS LUND Ltd 30 Aug 1973 [9 Sept 1972] 41991/72 Heading B3D A method of angularly indexing a crankshaft supported in the fixtures of a grinding machine comprises gripping the periphery of one end of the crank-shaft to perform at least a part of the indexing movement, and locating one or more crank-pins to be ground coaxial with the fixture axis prior to said movement. As described, the fixtures 10, Fig. 1, at one end of the crank-shaft is rotatably driven by the flange 14 of a spindle 12 and supports a chuck 16 rotatable in bearings 18. An abutment 20 is reciprocatably mounted in the front face of the fixture for engagement with a notch 22 in the web 24 of the crank-shaft, the main bearing 26 of which is supported in a throw block 28. The crank-shaft is aligned in the throw blocks and the abutment 20 engaged with the notch 22, the crank-shaft then being locked to the fixture by clamp pads closing on to the bearing 26 so that the pins aligned with the axis 27 of the fixture can be ground. Thereafter, the abutment 20 is withdrawn, the chuck 16 is actuated to grip the crank-shaft, the clamp pads release the main bearing, and the chuck is rotated to angularly index the crank-shaft to bring the other pins into alignment with the axis 27. In another arrangement shown in Fig. 1, a bolt 30 in the work head casting can be extended into a hole 32 in the flange 14 and a locator is mounted on the bed of the machine and can be swung to a position wherein a V-shaped section can accurately locate a crank-shaft pin. In this arrangement, the abutment 20 accurately locates the first pin to be ground. The bolt 30 is then extended to lock the fixtures in position and the abutment 20 is retracted, the clamp pads released, and the chuck 16 actuated to grip and angularly index the crank-shaft to an approximate position, accurate indexing being completed by engagement of the locator. In a further arrangement, the fixture 10, Fig. 2, at the other end of the crank-shaft has a pusher assembly 34 for laterally positioning the crankshaft and the locator is mounted on the fixture and consists of an arm 36.
