Title: Improvements relating to fluid operated metal and other grinding or cutting machines
IPC: B23F23/00
Filed: 1927-07-25
Abstract: 299,383. Gear Grinding Co., Ltd., and Orcutt, A. H. July 25, 1927. Driving machines.-In a fluid operated metal or other cutting or grinding machine, the supply system includes a rotary valve which is operated by a reciprocatory part of the machine for throttling the supply of fluid to the working cylinder when the ram is approaching the end of its stroke and a chamber d of variable volume containing a loaded movable piston is provided to absorb sudden pressure fluctuations. In the application to a gear grinding machine, the slide p carrying the grinding-wheel g and the plunger c operating the indexing mechanism are respectively operated by fluid pressure cylinders g, h supplied by a pump a through a distributing valve r, fluid being returned to the reservoir t by a pipe s. The chamber d carries a piston e which is loaded by a spring f or by a dead-weight or by compressed air. The throttling at the ends of the stroke is effected by a rotary valve i operated through gear wheels j, k, l by abutments o mounted on the slide p. As the plunger approaches the end of the stroke one of the abutments engaged a fixed tappet m<1> to move the valve to reduce the fluid supply. On the return stroke the valve is returned by the engagement of the same abutment with one of the spring tappets m.

Title: Improvements relating to apparatus for generating randomly timed electrical pulses
Inventor: INGHAM WILLIAM ELLIS
IPC: H04J3/26
Filed: 1953-07-17
Abstract: 790,761. Pulse generating arrangements; pulse modulation circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 19, 1954 [July 17, 1953], No. 19832/53. Classes 40 (5) and 40 (6). A train of pulses having a constant (or approximately constant) average repetition rate, but phase-modulated at random, is derived by periodically sampling the instaneous amplitude of a randomly variable sawtooth wave and converting the resulting amplitude-modulated pulses to phase-modulated pulses. The sawtooth wave is controlled by a source of random electrical noise so as to have either a continuous waveform of random frequency, or a regular waveform occurring at random intervals. In one embodiment a relaxation oscillator comprises a capacitor 7 which charges through resistor 8 to a predetermined voltage at which a trigger 4 and valve 5 discharge the capacitor 7. The slope of the long flank of successive sawtooth waves is, however, varied at random by varying the voltage at point 9 in accordance with the amplified output of a source 1 of electrical noise (saturated diode or gas discharge tube). The instantaneous amplitude of the irregular sawtooth is sampled periodically by a sampling pulse generator 61 rendering a diode 19 conductive at regular intervals to connect the output of cathode-follower 12 to the input of cathode-follower 23. The amplitude modulated pulses from cathode-follower 23 charge capacitor 28 to peak voltage through diode 27 and render valve 33 conducting. Between pulses the diode 27 cuts off, capacitor 28 discharges through resistor 29, and at a given level valve 33 cuts off so that its output pulses are duration modulated. This output is converted to phase modulated pulses by a flip-flop 36. It is stated that a second network similar to 27, 28, 29 may be added in to the first cascade. In a modification, the sample pulse generator 61 is omitted and the final output pulses used to control the sampling. In a further modification, a regular saw-tooth wave is first generated and this is initiated by a noise pulse of greater than predetermined amplitude. At a fixed time from the last output pulse, the amplitude of the saw-tooth wave is sampled and this random amplitude-modulated pulse is used to determine a random interval before the generation of the next output pulse (as above). On the generation of this output pulse, the sawtooth waveform is stopped until again initiated by a suitable noise pulse. It is stated that the random output pulses are used to control the transmission times of a number of radio transmitters so as to reduce the chances of overlap.

Title: Apparatus for installing and removing flow valves in or from a well tubing
IPC: E21B23/03
Filed: 1969-04-18
Abstract: 1,246,563. Wells &c. CAMCO Inc. 18 April, 1969 [1 May, 1968], No. 20050/69. Heading E1F. A device for removing or inserting a flow valve 20 from or into its seating 18 set in a side pocket 16 of a well tubing 10 having a number of such side pockets longitudinally spaced, each side pocket having above it a sleeve 22 with a vertcial slot 24 and an angled bottom edge 26, the wall of the tubing having a shoulder 28 above the slot 24, comprises a body portion 30 having an internally slideable shaft 38 with two vanes, see also Fig. 7, not shown, between which is pivoted a plate 46 on a shearable pin 50. To the lower end of the body portion 30 is fixed a sheath 36, Fig. 4B, having pivoted to its upper end an arm 32 which is joined by a pivot 71 and shearable locking pin 72 to a connecting rod 74 adapted for either inserting or removing the valve 20. For inserting the valve, the device is fixed to a wire at 40 and is lowered until it is adjacent the side pocket 16, the. plate 46 being of such a width as to pass through the slot 24 in the sleeve 22 and in the similar sleeves corresponding to the side pockets above the pocket 16. The plate 46 is resiliently biased by a spring 48 to ride over obstructions as the device moves downwardly. When adjacent the pocket 16 the device is moved upwardly so that the plate 46 abuts the shoulder 28 which allows the body portion 30 to lift relative to the inner shaft 38 and release the arm 32. which had previously been held by a bolt 62, Fig. 4B, abutting a shoulder 60 on the end of the shaft. The arm 32 has a spring-loaded plunger 64 which pushes the arm from the sheath 36 to a position shown in Fig. 2. The device is then lowered so the valve 20 wedges on the seating 18, the valve having been angularly aligned with the seating by the plate 46 engaging in the slot 24. Further lowering causes the locking pin 72 to shear thus allowing the connector 74 to pivot freely so that the valve will be lowered into its seating. On raising the device, the connecting rod 74 separates from the valve 20, an upward jar causing breaking of a shear pin connection between the two, and the plate 46 again abuts the shoulder 28 but now the device is pulled further upwards causing the pivot pin 50 to shear and the plate 46 to be retracted by the spring 48, see Fig. 6 (not shown) allowing the device to be freely raised. For extracting the valve 20 the method is similar but a different connecting rod 74 is used, having an upwardly directed shoulder engaging over a downwardly directed shoulder on the valve.

Title: Hydraulic control system
IPC: F15B21/047
Filed: 1960-06-10
Abstract: 918,452. Hydraulic apparatus. CESSNA AIRCRAFT CO. June 10, 1960 [July 3, 1959], No. 20503/60. Class 69 (2). An hydraulic system for controlling the operation of a fluid-actuated motor 18 and for preventing cavitation therein when large inertia forces are transmitted thereto comprises reversing valve means 30 having two operative positions for connecting a supply passage 1 with one or other of circuit-control passages 36, 37 communicating respectively with the opposite ends of the motor, the other control passage being connected to a return passage 38, and a neutral position in which both circuit-control passages are blocked from the supply passage and the return passage, and independent valve means 43, 44 effective when the reversing valve means is in its neutral position to afford flow of fluid from the return passage directly into either of the circuit control passages when the pressure in the latter drops below the pressure in the return passage. The motor, which may be of the piston-and-cylinder type, or, as shown, the vane type having its rotor 24 connected to the boom 26 of a power shovel, has its chambers 50, 51 connected by lines 19, 20 to ports 39, 40 in a valve housing 17. The ports are connected to the circuit-control passages 36, 37 which can be selectively connected by movement of the reversing valve spool 30 to the passage 16 leading from a pump 12 or to the return passage 38 which is connected by a line 22 to a reservoir 13. When the spool 30 is moved to the right, the passage 36 is connected by a one-way valve 35 to the supply passage 16 so that fluid pressure is communicated to the chamber 50 to move the boom counterclockwise, fluid from chamber 51 passing through passage 37 and return passage 38 to the reservoir 13. When the spool is returned to its neutral position, the inertia force of the boom 26 and shovel 28 may cause an increase in the pressure in the chamber 51, which pressure is transmitted to passage 37 and, at a predetermined value, opens an adjustable pressure-relief valve 42, such as is described in Specification 918,451, to relieve the pressure and pass fluid into the return passage 38. The inertia force of the boom may also cause a drop in the pressure in chamber 50 to a value below that in the return passage 38. The drop in pressure causes the valve 43 to open and fluid in the return passage to flow into the passage 36 and the chamber 50 to prevent cavitation therein. Similar action occurs when the spool 30 is moved to the left to move the boom clockwise. The valve housing is formed with passages 10, 11 to permit the valve to be used in association with other valves in a multiplevalve bank.

Title: Improvements in devices for eliminating the air bubble formed when launching a torpedo under water by means of compressed air
IPC: F41F3/10
Filed: 1933-07-20
Abstract: 424,631. Launching torpedoes. DIAZ, M. G., and SOCIEDAD ESPANOLA DE CONSTRUCCION NAVAL, 25, Calle de Sagasta, Madrid. July 20, 1933, No. 20526. Convention date, July 20, 1932. [Class 9 (ii)] An exhausting valve for returning the launching air from a torpedo tube into a submarine to avoid an external air bubble is opened by pneumatic means either a given time after the opening of the launching valve or when the pressure in the tube falls to a given value. In the form shown, the casing N of an exhausting valve V is connected at C to the breech end of the torpedo tube and at 30 to the inside of the submarine. When the torpedo is launched, the air pressure is transmitted through pipe 2, 3 to a cylinder P where it depresses a piston Q and removes a catch F from the stem v of a distributing piston valve D, which is moved to the left by a spring G. Air at a lower pressure than the launching air then passes from a source A-B through the valve D to a chamber B<1>, taking a given time to build up sufficient pressure there to open the exhausting valve V by its action through pipe 8, 9 on a piston E on the valve stem before the torpedo has left the tube. The air from the chamber B<1> then passes through pipe 10, 11 to another chamber B<2>, where after a further predetermined time interval it acquires sufficient pressure to return the piston valve D to the right, the chamber B<2> being connected to the left of the casing of the valve D by a pipe 12, 13. The catch F then relocks the stem v of the valve D, while the exhausting valve V again closes to prevent entrance of water into the submarine. In case of emergency, the valve D may be thrown to the right by hand operation of a lever P<2>. In a modification, instead of the chambers B<1>, B<2>, the left of the casing of the valve D is connected to the launching valve so as to receive air pressure when the torpedo is launched. This moves the valve D slightly to the left, allowing a spring catch to disengage itself. And when the pressure in the torpedo tube has fallen to a given value, the valve D is moved by a spring to its extreme left to allow low pressure air to pass to open the exhausting valve. The valve D is returned to the starting position by a hand operated lever. In a modification of the last arrangement, an air chamber into which pressure is gradually built up is provided to operate the hand lever to return the valve D automatically to the starting position.

[Class 5 (ii).] To count chickens as they leave the roost an outlet hole 2 adapted to be closed by a sliding door 3 is arranged in the house and a board 5 fitted in front thereof. A frame 6 open at each end is placed on the board and is detachably secured to the house by hooks. A plate 9 is mounted on a vertical pivot 16 at one side of the frame 6 and is attached at its inner end to a spring 10 that causes it normally to project across the outlet path. A rod 11 connects the further end of the plate to a counting device 12. As each bird leaves the house it displaces the plate 9 against the pressure of the spring 10 and so actuates the counting device. On the other side of the box a plate 14 is secured by fitting in the appropriate pair of a series of grooves 13 so that the outlet path is of suitable size for the chickens in the house. Instead of being fitted in grooves the plate 14 may be carried on adjustable rods or screws.
