Title: Improvements in and relating to devices for controlling the flow of liquids
IPC: F15B13/02
Filed: 1940-12-31
Abstract: 544,599. Valves. ACROTORQUE CO. Dec. 31, 1940, No. 18250. Convention date, Oct. 12. Addition to 528,621. [Class 135] The parent Specification describes a device for controlling the flow of a liquid comprising an inlet passage, an outlet passage leading to the mechanism to be actuated, a discharge passage, a valve for controlling the supply of liquid from the inlet to the outlet passage, a valve for controlling the flow of liquid from the outlet passage to the discharge passage and means responsive to change in the rate of flow of the liquid to the outlet passage for automatically closing the supply control valve and opening the discharge control valve. According to the invention these two valves are so arranged as to be incapable of independent movement and the supply control valve which is latched in the open position and is automatically unlatched by the means which are responsive to change in the rate of flow is provided also with manually operable means for unlatching it independently of the automatic release. The body 5 has an inlet passage 6, an outlet passage 7 and a discharge passage 8. The inlet is controlled by a valve 14 and the discharge by a valve 23 which controls a duct 92. Flow from the inlet to the outlet takes place through passage 39 and bore 38. To put the device into operation, the lever 29 is depressed about its pivot 30 against a spring 31 and a pin 34 on the lever is brought beneath a latch 35. The valves 14, 23 are rigidly connected by a stem 20 and are connected to lever 29 by a stem 24 and pin-and-slot 90. The bore 38 contains a piston 40 loaded by a spring 44. When the lever is depressed, the valve 14 is opened, 23 closed, liquid flows to outlet 7 and raises piston 40 a flared cap 93 on the stem of which passes and is held above a plunger 37. If the rate of flow decreases, the piston 40 descends and moves the latch 35 to release the lever 29, close the valve 14 and open the discharge duct 92. If it be desired to cut off the supply before the automatic cut-off described above comes into operation, the lever 29 is provided with an unlatching lever 94 pivoted at 95, loaded by a spring 96 and prevented from rotating clockwise by a stop 97. When lever 29 is depressed, the lever 94 meets the latch 35. If then the knob 98 be raised the end 99 of the lever 94 swings the latch counter-clockwise and releases the lever 29. Any liquid trapped below the valve 14 can escape by way of the stem 20, and passages 100, 101. Liquid collected around the lower part of the stem of piston 40 can pass through duct 102 and thence to passage 8. The valve 14 has packing 106 held by a nut 103 itself held by a spring 104.

Title: Improvements in or relating to transmission arrangements
IPC: F16H37/08
Filed: 1965-04-30
Abstract: 1,106,790. Change-speed gear. ZAHNRADFABBIK FRIEDRICHSHAFEN A.G. 30 April, 1965 [2 May, 1964], No. 18315/65. Heading F2D. An infinitely variable transmission 2 has its output shaft 6 connected to the sun 7a of an epicyclic gear 7, the annulus 7c of which is connected to output shaft 8 and the carrier 7b can be driven from constant speed shaft 9, linked to input shaft 1, by change speed gear trains and clutches 12, 15, 10, K 1  or 13, 16, 11, K 3 . The range of transmission 2 can thus be multiplied by driving the carrier 7b at two speeds from shaft 9. The output shaft 8 can be driven direct from shaft 6 by applying clutch K 2  or can be driven in reverse by applying brake K 4  to carrier 7b. Engagement of clutch K 1  produces slow speed range, K 2  direct range from shaft 6 and clutch K 3  high-speed range. With this transmission, the transmission 2 is adjusted from max. to min. for the 1st speed range, from min. to max. for the 2nd speed range and from max. to min. for 3rd speed range but for the reverse range it has to be adjusted from min. to max., whereas in Fig. 2 (not shown) the transmission 2 does not have to be adjusted back to min. The carrier can be driven from the shaft 6 or 9 at a step-up gear ratio. Fig. 3 (not shown) provides a fourth speed range forming a high-speed range starting at the max. of the variable shaft; two clutches are engaged for each speed range. Fig. 4 (not shown) is similar to Fig. 2 but has an additional step-up gear train from the constant speed shaft. For a vehicle the variable speed transmission, Fig. 5 (not shown), is preceded by a hydrokinetic torque converter or coupling provided with a by-pass clutch which is engaged after the engine has picked up speed. Pumps deliver pressure according to input and output speed and the difference in pressure is utilized to control the variable transmission and the pump pressures or the pressure difference may be used to actuate the clutches and brakes. Fig. 6 shows an epicyclic gear system comprised solely of externally toothed wheels. The variable transmission 2 may be a hydrostatic or mechanical transmission.

Title: Method and apparatus for generating electrostatic images
IPC: G03G15/32
Filed: 1972-04-21
Abstract: 1357966 Corona charging apparatus INTERNATIONAL BUSINESS MACHINES CORP 21 April 1972 [16 June 1971] 18554/72 Heading H1X An electrostatic image is generated on a surface of a dielectric by generating a concentration of ions in a pressurized gas, forming a plurality of individual ion streams from the ionized pressurized gas, selectively applying an electric field to the streams to produce modulated streams, and directing the modulated streams upon the surface to form the image. Ions are generated in a chamber 1 as described in Specification 1,357,965 to which gas, e.g. air under pressure is admitted through an inlet 2. Ion streams emerge from ports 3 into a head assembly 4 comprising channels 4a1 to 4a7 having insulating side walls, conductive upper walls 5a1 to 5a7 connected by lines 15a to 15g to a character pulsing means (CPM ), and conductive lower walls 5b1 to 5b7 connected by lines 16a to 16g to a D.C. power supply applying a constant voltage of, e.g. -15v. The CPM supplies negativegoing pulses of 15v. During a pulse the nett field across a channel is zero so the ion beam passes through the channel to the previously oppositely charged dielectric medium to perform a write operation. Between pulses the field across a channel is 15v so the ion beam is deflected to the lower wall of the channel and few ions reach the medium.

Title: Switch arrangement for magnetic transducer selection
IPC: G11B5/004
Filed: 1957-06-14
Abstract: 833,545. Electric digital-data-storage apparatus. LIBRASCOPE Inc. June 14, 1957 [Oct. 8, 1956], No. 18815/57. Class 106 (1). A magnetic transducer selection arrangement comprises a matrix array of transducers, means for selectively applying an energizing signal to one of said transducers and means for con. trolling the operation of said head for reading or recording. As shown, Fig. 1, a 4 X 4 matrix of read/write heads for a magnetic drum store comprises centre-tapped windings 10. Recording.-Selection of a head 10 is accomplished by selection of the appropriate row and column. Row selection is by flip-flops 144 and 146 which are connected to diode gating circuits 141 such that two low voltage inputs to the appropriate gate select the corresponding row by applying a high voltage thereto. Column selection is achieved similarly by flipflops 92, 94 and the gating circuit 85. A high voltage from a flip-flop 82 indicates that a recording is to take place and a " 0 " or " 1 " is recorded according to the state of a further flip-flop 108, a high voltage from the left-hand side opening the appropriate gate 75 to send recording current through the left-hand winding of the selected head 10 for recording a " 1," a high voltage on the right-hand side opening the appropriate gate 101 to record a " 0." The output from the left-hand side of the flip-flop 82 causes a triode 168, Fig. 2, to conduct thereby biasing diodes 160, 162 to isolate the reading circuits from the head 10. A switch 118 is normally closed for recording but may be opened to prevent recording taking place due to the high value of the resistance 72. Reading.-The flip-flop 82 is changed over to produce a low voltage at its left-hand terminal thereby closing the gates 75, 101 to prevent triodes 70, 114 conducting. The selected column gate 85 is opened, thus effectively earthing the centre tap of the output winding of the transformer 182. The triode 168 is cut-off to render triodes 164, 165 conducting and supply a high voltage to the diodes 160, 162. Row selection is as for recording. The information read by the head 10 is amplified by a push-pull stage comprising the triodes 164, 165 and transformer 182 whence after further amplification by triodes 202, 204, a pulse 262 whose polarity depends on whether a " 1 " or " 0 " has been read passes via a cathode follower 220 to an output amplifier 230. The arrangement of tubes 164, 165 and 202, 204 is adapted to reduce noise signals.
