Title: Improvements in or relating to carburettor throttle controls for internal combustionengines
IPC: F02D9/00
Filed: 1937-12-09
Abstract: 507,160. Spray carburetters. TRIGGS, W. W. (California Machinery & Supply Co., Ltd.) Dec. 9, 1937, No. 34160. [Class 7 (iii)] In a carburetter having a choke valve and an idling passage for supplying fuel to an orifice adjacent the throttle valve, suction-operated means are provided for moving the throttle valve towards its closed position, the action of these means being modified in accordance with the movements of the choke valve. As shown in Fig. 1, the closing position of the throttle is limited by a stop-screw 55 carried by an arm 46 loosely mounted on the throttle shaft 15 and connected to a piston 42 which operates in a cylinder 37 and is subjected to the suction on the engine side of the throttle through passages 62, 63, 58. During idling, the suction causes the piston to compress a spring 49 and maintain the throttle slightly open to permit fuel to be drawn from the idling passage 34. If the engine tends to stall the reduced suction in the induction pipe permits the spring 49 to open the throttle slightly. During overrunning the high suction in the induction pipe moves the piston 42 against the resistance of springs 49, 51 and closes the throttle further to cut off the fuel supply through the idling passage. When the choke valve is operated at starting, a cam 66 lowers a piston valve 64 to prevent the transmission of the suction from the passage 58 to the passages 62, 63 or to the passage 62. In the modified construction shown in Figure 4, the piston 42 is opposed by a single coil spring 70 and its travel is limited by a stop 71 at the point at which the idling orifice 34 remains open. When the choke valve is closed the cam 66 depresses a rod 72 to unseat a valve 73 which puts the chamber 39 into communication with the atmosphere; thus the piston is not responsive to pressure changes in the inlet manifold when the choke valve is closed.

Title: Automatic control of apparatus for drawing tubing from molten glass or like thermoplastic material
IPC: B29C48/92
Filed: 1961-09-26
Abstract: A control system for maintaining the diameter of drawn glass tubing includes signals from two diameter measuring means, one where the tube is hardened and one where the tube is still in the plastic state, the first signal being compared with a standard signal to give a third signal for comparison with the second signal, the resultant variations giving a signal used to vary the pressure in the interior of the tube in the plastic zone. As shown, tubing is drawn from a reservoir 11 of molten glass through the annular orifice between a tank 12 and bell 13 which is constantly provided with air pressure from a fan 20 to form the tubing. The diameter measuring means in the plastic zone comprise hollow pressure conducting tubes 14, 15 inside and outside the tube which transmit pressures to a differential pressure gauge and transmitter 16 which emits the second signal, proportional to the pressure difference, to a preset pneumatic pressure controller 18, any variations from the preset value operating a pneumatic motor valve 19 to adjust the internal pressure in the tubing in the internal zone by regulating the bleeding of air from the system. The controller 18 is variably preset from a diameter sensing unit 21 which gives the first signal to a controller 22 which is compared with a predetermined <PICT:0943305/C1/1> standard signal 23 to give the third signal which presets the controller 18.  To avoid variations in this third signal due to only minor variations or a short length of defective tubing, the controller 22 is set to respond to low frequency variations in tubing diameter which controller 18 is set to respond to high frequency variations in pressure.  A third sensing device may be used to give diameter variations after the tubing has cooled to room temperature and a signal therefrom may be used in place of the standard signal 23. The tubing gauge disclosed in Specification 905,307 may replace the tubes 14, 15 for measuring the diameter in the plastic zone.

Title: Hydraulic torque converter
Inventor: DUNDORE MARVIN WALTER
IPC: F16H41/26
Filed: 1957-11-07
Abstract: 864,358. Torque converters. TWIN DISC CLUTCH CO. Nov. 7, 1957, No. 34764/57. Class 69 (2). A torque converter, driven for example by a governed diesel engine, has its stator 27 and pump 15 in the outward flow portion and its turbine 21 in the inward flow portion of the circuit, and the U-shaped passages 16, 22 are unbladed. Each blade in the elements 15, 21, 27 is oriented as set forth in the Specification. Liquid is forced through a cooling system by means of a pump run off the engine and this forced circulation is augmented at low speed ratios by the circulation in the converter. At high ratios, the liquid head at the inlet of the turbine tends to oppose circulation in the converter and the pump acts alone. When a speed ratio is reached between 8 and 9, torque ceases to be transmitted. Since the channels between the pump and impeller blades are wider at the radially outer end than the inner end, compensation is made to prevent variations in pressure by narrowing the axial width of the channels in a radially outer direction. In one form, the pump blades are interspersed with smaller blades which prevents a tendency for the liquid to circulate between blades. The stator has variably-pivoted blades.

Filed: 1971-07-26
Abstract: 1320082 Programmed control of machine tools BENDIX CORP 26 July 1971 [5 Aug 1970] 34875/71 Heading G3N In a numerical control system, operating in a set feed per revolution mode, the iterations of the interpolators are determined by pulses from a spindle transducer. As shown, a workpiece 14 is driven by a spindle 12 the rotation of which is sensed by a transducer developing pulses which are fed over a line 40 to an over-ride interpolator 32 which overflows at a value dependent on the setting of a percentage control 46, 48. The overflows are fed to a feedrate interpolator 34 which overflows at a value dependent on the contents of a feed-rate store 30 set by a signal from a tape reader 26 responsive a part program on a tape 28. The output of the interpolator 34 is applied to an axis command interpolator 24 which actuates a slide control 22 to position a slide 20 in dependence on the part program on the tape 28 at a feed-rate determined by the spindle speed. A switch 44 enables the feed-rate to be maintained at a rate determined by an oscillator 52. A manual device 54 enables the slide to be jogged when the spindle is stationary. During thread-cutting operations the interpolator 32 is by-passed, the spindle pulses on a line 40 being passed through an AND-gate 58 enabled by a manual or tape controlled device 56.

Filed: 1935-12-16
Abstract: 467,430. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and RUST, N. M. Dec. 16, 1935, No. 34882. [Class 40 (v)] A.V.C. is effected by varying the value of a feed-back impedance in the cathode circuit of a valve or valves whose gain is to be controlled. In one embodiment, Fig. 11, shown in simplified form in Fig. 2, a tuned amplifier comprises three valves V1, V2, V3 the cathodes of valves V1, V3 being connected together and to a variable cathode feed-back impedance CR, Fig. 2, constituted by a diode D, Fig. 11, the resistance of which is controlled by a potential dependant upon signal strength derived from a gain control line A.V.C. through a filter AVR, SC1, SC2. The diode D is shunted by a grid biasing resistance BR1 in series with a shunt combination of inductance resistance and capacity CR3. The positive A.V.C. potential on the diode anode is derived from the cathode of a valve to which increasingly negative grid bias is applied as signal amplitude increases, Fig. 12 (not shown). The diode D may be incorporated in valve V3 as indicated in dotted lines. In a second embodiment, Fig. 13, shown in simplified form in Fig. 4, two variable impedances are used constituted by a diode 1D shunted by a resistance DR connected between the cathode of valve V3 and the grid of the preceding valve V2, and a diode 2D in the cathode circuit of valve V3. A potential from the line A.V.C. which becomes increasingly positive with increase in signal amplitude is applied to the cathode of valve V1, and from a tapping TCR on a potential divider CR1 to the cathodes of valves V2, V3. The diode 2D is shunted by a tuned circuit ATC3 and its anode returned to a point T2 of fixed positive potential so that its resistance increases as its cathode rises in potential, while the resistance of diode 1D decreases as its anode rises in potential. The A.V.C. potential may be derived from the cathode of an anode-bend detector, Fig. 14 (not shown). Simplified circuits with variable feed back impedances connected in other positions are also described. Electron-beam valves of the type described for example in Specification 403,973 are preferably employed.

Filed: 1962-09-14
Abstract: 1,005,672. Checking receipts. UNIVERSAL MATCH CORPORATION. Sept. 14, 1962, No. 35086/62. Heading G4T. A depository machine includes means to validate, and means to record the image of a deposit tag prior to actuation of feed means on which a deposit is fed from an acceptance position to storage means, during which motion an image of the deposit is recorded. In one embodiment a deposit tag (Fig. 7) bearing a list of articles to be deposited, e.g. cheques &c., filled in on a portion 34, duplicated by carbon on the portion 32, and folded as shown, is pushed into the machine between guides 15, 16 until it contacts a switch which causes the transaction number, the date and the time to be recorded on the tag by pressing it against a carbon or inked ribbon over figure wheels. A microfilm camera is triggered to record an image of the portion 34 together with indicators showing the setting of the figure wheels. The camera simultaneously takes a photograph of a pair of sideby-side feed belts 71 which are stationary at this time. The tag is then removed and separated along the fold 33 and the portion 32 replaced in the machine. The portion 31 is placed in a hopper 12 and the cheques &c. to be deposited are placed on top followed by a weight 14, and coins and other bulky articles are placed in trapdoor 22 leading to a storage receptacle 22. A counting device may be provided to indicate the value of the coins. Depression of a feeler on a switch 81 by the presence of articles to be deposited causes a pair of feed wheels 89 to feed the articles one by one on to the pair of conveyer belts 71 and below a pressure roller 90. A switch situated between the conveyers is tripped each time an article passes and a photograph of the article while alongside the portion 32 of the deposit tag is taken. All articles of a single deposit placed in the hopper 12 are passed by the conveyers into a compartment 101 of a drum store 100 which is stepped one compartment each transaction. A further switch tripped by the articles steps an article counter. When the transaction has finished, i.e. when switch 81 has been released, the total number of articles deposited and the value of the coins are printed on the tag portion 32 which is returned and a further photograph showing these values is taken. In modifications two separate tags may be used and have tandem printing devices working one on each tag or a single tag equivalent to the portion 32 may be used. The setting of the print wheels may be displayed mechanically, electrically, optically or may comprise electronic display tubes.
