Title: Improvements in or relating to dough dispensers for depositing scrap-dough on moving bands of fresh dough
Inventor: MCCONNELL DERRY
IPC: A21C9/08
Filed: 1966-06-14
Abstract: 1,149,267. Apparatus for dispensing dough. BURTON'S GOLD MEDAL BISCUITS Ltd. 13 June, 1967 [14 June, 1966], No. 26364/66. Heading A2A. Apparatus for dispensing a zig-zag strip of scrap dough on to a moving band of fresh dough (not shown) comprises: an open-bottomed depositor 1 pivotally mounted at its upper end (into which scrap dough is fed) a piston-cylinder device 4 operated by fluid pressure, e.g. compressed air, for swinging the depositor to and fro across the moving band of fresh dough, and a fluid-pressure control system actuable by the depositor 1 to control the flow of fluid to the device 4. The strip of scrap dough is dispensed from the open bottom of the depositor 1. The device 4 may comprise a double-acting cylinder 7 and piston 3 connected to a ram 2 for swinging the depositor 1. The ram 2 may be detachably and adjustably pivoted to a swinging link 9 having a roller, which makes contact with the depositor 1. The amplitude of the swing of the depositor 1 may be varied by inserting the pivot pin into a desired hole of a series of aligned holes in the link 9. Alternatively, the link 9 may be pivotally connected to the depositor. The control system may comprise a slide-valve 6 actuated by fluid pressure, which slide-valve directs pressure fluid supplied by a pipe 5, alternately, through pipes 18 and 19 provided with throttle-valves 20 and 21, to opposite ends of the cylinder 7, and a pair of on-off switches 10 and 11, actuated by an arm 12 on the depositor, for directing pressure fluid, supplied by a pipe 15 branching from the pipe 5, alternately, through pipes 16 and 17 and optionally through delaying throttle-valves 23 and reservoirs 22, to opposite ends of the slide-valve 6.

Title: Arrangement for indicating a leakage between the cooling systems of a turbo-generator
IPC: H02K9/00
Filed: 1960-07-29
Abstract: 881,366. Cooling dynamo-electric machines. BROWN, BOVERI & CIE A.G. July 29, 1960 [July 31, 1959], No. 26566/60. Class 35. In a turbo-generator with a cooling gas (e.g. hydrogen) in the machine casing and a cooling liquid (e.g. oil) flowing through or adjacent the stator conductors, leakage between the two cooling systems is detected by using as the liquid coolant liquid which has been de-aerated and saturated with a gas which is inert to it, and passing this liquid through the machine in a circuit which includes a tank provided with a manometer. If any of the gas coolant penetrates into the liquid coolant system, which is automatically kept at a lower pressure than the gas, then this is indicated by the manometer. The liquid may be saturated with hydrogen or nitrogen and in the latter case the manometer may be replaced by a device which detects hydrogen. The pressure of the saturating gas may be above atmospheric pressure.

Abstract: 265,932. B³cher, C. Feb. 12, 1926, [Convention date]. Incrustation, preventing.-In the process described in Specification 260,233 in which iron water pipes are protected from attack by water containing free carbonic acid or oxygen by causing a deposit of calcium monocarbonate to be precipitated on the walls by adding to the water a predetermined quantity of calcium hydrate, the solution of calcium hydrate may be prepared in the apparatus shown in Fig. 1, in which lime passes from a silo 2 by a worm-conveyer 5 operated by a motor 4 to an elevator 7 whence it passes through a pipe 9 to a perforated vessel 10 at the top of a column 11 contained in a tank 1, water and compressed air being introduced through a nozzle 12. The lime water is led off from the top of the tank 1 through a pipe 18. The supply of lime and water is adjusted by means of a water meter 15 arranged, when a predetermined quantity of water has passed, to operate an electric switch 24 which operates a second switch 26 which causes the motor 4 to feed the lime for a predetermined time. The flow of water may be indicated on an indicator 29 operated from a Venturi tube 30. Sediment is washed out by jets from pipes 32 supplied intermittently through a valve 38 operated by gears 39 and a link motion 36 from the elevator pulley 41. The plant for mixing the lime water with the water supply is shown in Fig. 2, and comprises a concrete chamber divided into compartments by a partition 20. Lime water passes from the pipe 18 through a mixing nozzle 19 and a hopper 21. The water passes through a filter 22 and is led off through a pipe 23.

Abstract: 1502056 Measuring temperature electrically AMERICAN MEDICAL ELECTRONICS CORP 25 June 1976 26605/76 Heading G1N The measuring and display circuits of a temperature sensing system are energized through an electronic switch for a predetermined time interval after initiation. The measuring system comprises a probe 20, Fig. 2, connected to a bridge circuit 24 to produce an unbalance signal on line 28 representative of the test temperature. This is augmented at 30 with a voltage dependent on the rate of change to provide at 32 the expected final value of the test temperature, which is then converted at 14 to a proportional pulse rate. Closing a spring- loaded switch 58 energizes the system from power supply 17 via electronic switch 18 and causes control unit 54 to allow clockpulses from generator 56 to be counted at 42 and displayed at 44. After 20 seconds the control unit feeds the temperature measuring pulses from converter 14 to counter 42 for a further fixed period, after which electronic switch 18 cuts-off the power supply.

The fibres are carried down a shaft 5 having air openings 6 by air or gas under pressure from nozzles 4 and are deposited on an endless conveyer 7 in a continuous mat or lap. A suction chamber 8 may be provided below the conveyer 7 while a presser plate 11 is provided above the fibres. A knife blade or scraper 12 reciprocated by a crank 14 is provided to free the lap from the conveyer 7, the material passing to a second conveyer 15 where it is sprayed with binding material at 16 while air is circulated between pressure and suction conduits 17, 18 having slots 17a, 18a and flanges 19. A sheet of paper may be secured to the lower surface of the mat by latex, resin or other adhesive. The blasts carrying the fibres downwards may be controlled by directing the gas into a shaft 20 expanded at 21, Fig. 2, the blasts being received in a chamber 22 and conducted away through conduits 23.

Piston valves.-A cylindrical drawing-off device for use with viscous liquids has a circular discharge opening 8, Fig. 1, normally closed by a spring-controlled plunger 10; a small opening 8<a> is preferably left between the edges of the plunger and the opening as this is found to prevent drip. The plunger is adapted to open under the influence of a pump when such appliance is used for withdrawing the liquid, but may be opened by hand by pulling on the knob 12. The knob 12 and the boss 14 have segmental portions so that the valve may be held open by relative rotation of these parts into the positions shown in Fig. 3. The plunger may be locked in the closed position by a pin (not shown) on the rod 11 moving along a groove in the cap 9 or boss 14 and engaging a bent part of the groove by a partial rotary movement of the knob 12.
