Title: Improvements in or relating to liquid pressure apparatus
IPC: G01F3/18
Filed: 1944-03-03
Abstract: 575,647. Hydraulic motors. AUTOMOTIVE PRODUCTS CO., Ltd., and SADLER, F.A.D. March 3,1944, No. 4037. [Class 69 (ii)] [Also in Group XXVI] A motor piston 13 is reciprocated by pressure fluid admitted alternately to working spaces 27 by a pilot valve 15, which is reversed by pressure fluid admitted to pilot working spaces 35 at the ends of the strokes ; the pilot valve is allowed to complete its reversing movement by use of a byepass 37 opened during the initial movement and closed towards the end of the stroke, remaining open after the closure of the reversing valve device constituted by the outer end of the oblique passage 36a and an exhaust port 24. The piston may be formed with rack teeth on its lower side meshing with a pinion on a spindle, which is thus oscillated. The space around this spindle constitutes the exhaust port 24, with which a port 30 in the piston communicates permanently, while inlet ports 20, 20a communicate permanently with grooves 34, 34a in the piston. The piston has' been moved to the left-hand position shown by fluid entering by port 20a and passing through groove 34a, valve groove 32a, port 28a, and groove 26a, to the end space 27a, fluid in the other working space discharging through ports 29, 30 and piston groove 31 ; a pin 17 guides the piston; in reaching this position it has first put working space 35 in communication with inlet port 20 through passage 36 and then put corresponding passage 36a in communication with exhaust port 24. The valve now starts to reverse, and with it the piston, and when the piston movement has closed passage 36a to exhaust port 24, byepass 37a has been connected by the valve motion through groove 32a with space 35a, and connects this space with discharge space 24 till later in the piston stroke. Fig. 6 shows a motor pump unit in which the pilot valve 15 moves in coaxial bores 68, and controls fluid supply to and discharge from the cylinder of a main motor piston 56 working in spaces 59, 59a and an auxiliary piston, both of which serve as pump plungers. Fluid is supplied through passages 52, 53 and 53a and discharged from spaces 51, 51a. The pistons are hollow, and slide on fixed grooved pistons 65, 65a, fluid being supplied to and discharged from spaces 27. The valve is moved by fluid supplied through passages 76, and main discharge passages 74a and byepasses 75a, 76a are provided. The fluid supply to the auxiliary motor is controlled by the main motor so that the two move oppositely.

Filed: 1937-02-11
Abstract: 490,368. Printing-telegraphs. MORRELL, F. O. Feb. 11, 1937, No. 4070. [Class 100 (iv)] Alarms; letter-spacing mechanism.-In a telegraphic receiver for printing or perforating messages on a tape or sheet, an alarm, controlled by the tape or sheet and the feedmechanism therefor, is provided for indicating that the tape or sheet has not been fed, and consequently that the message has been obscured. In the mechanism shown in Fig. 1, a feed-roller 2 for the tape 1 is operated by a ratchet-wheel 3, and a co-operating pawl 4 formed on a link 16 in connection with a rock-shaft 11. The link 16 is now provided with a hook 5 co-operating with a link 6 in connection with a lever 10 which is provided at the top with friction-pads 14 for the tape. The lever is provided at the bottom with a pivoted arm 9 which co-operates with a lever 17 for closing the contacts of a slow-acting relay in circuit with a lamp or bell. Normally on operation of the pawl, the tape is fed and the arm 9 permits the contacts to open before the relay is energized. If however the tape is not fed, the contacts remain closed and the alarm operates. The relay may be employed also for sending a warning to the transmitting-operator. When a signal that does not require tape-feed is received, the link 16 is rocked by a cam 13 and the hook 5 and pawl 4 are disengaged.

Filed: 1960-02-05
Abstract: In a process for the purification of polyethylene, obtained by polymerization at pressures above 500 excess atmospheres, by freeing it from gaseous and volatile non-gaseous constituents including unreacted monomer, in which the polyethylene, after reaction using a catalyst in a reaction vessel, is led therefrom first into a separator which is at a lower pressure than the reaction pressure, preferably less than 5 excess atmospheres and thence in finely divided form with a large surface area into a degasification chamber in which the polyethylene is subjected to vacuum treatment and thence to an extruder, provision being made to exclude air over the whole path of the polyethylene from the reaction vessel to the extruder, steam is introduced into the separator at a temperature of about 150 DEG C. and is discharged from the separator together with a part of the gaseous and volatile constituents.  Further steam, water or an organic solvent may be added to the polyethylene after it leaves the separator and before it enters the degasification chamber.  Polymers miscible with polyethylene may be added thereto in the separator and further processed therewith.  Apparatus suitable for carrying out the process of the invention is described and illustrated.

Abstract: 357,057. Coke ovens. STILL, C., Recklinghausen, Westphalia, Germany. Feb. 10, 1931, No. 4163. Convention date, Feb. 11, 1930. [Class 55 (i).] In the use of coke ovens in which the distillates are withdrawn separately from the gas collecting space 12 over the charge, and from ducts 28 in the charge, the pressure in the space 12 is maintained constant and at 0 mm. (that is, at atmospheric pressure) while the pressure in the ducts 28 is reduced as the coking process proceeds to at least 100 mm. and finally raised again to 0 mm. water gauge. Each coke oven has an opening 6 leading to an ascension pipe 7 which opens into a main 8, a liquid seal 9 being provided to close the main. Ducts 28 are formed in the charge by pushing iron rods through guiding tubes 24, 25, and withdrawing the rods, gas outlet pipes 26 then being inserted and pressed into the ducts. Water sealed covers 13 are then placed on gas outlet boxes 14 which lead by conduit 18 to a byepass chamber 19 which may be sealed from a subsidiary main 10 by lowering a bell 20 into liquid in the chamber 19. A throttle valve 22 is provided to control the degree of exhaust in the ducts 28. The gas drawn off from the ducts 28 has a high heating value, and large content of hydrocarbons of the nature of benzine, and the period of carbonization is reduced by reason of the gas flow due to the high partial vacuum.

IPC: H03F1/50
Filed: 1953-02-16
Abstract: 731,980. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 16, 1953 [Feb. 16, 1952], No. 4208/53. Class 40 (6). [Also in Group XL (b)] The load impedance of a video amplifier in a television receiver includes a coupling circuit in the form of a low-pass filter having means for adjusting the components of the filter so as to decrease the pass range at the high-frequency end thereof and simultaneously to change the magnitude of the load impedance so as to increase the gain of the amplifier. As illustrated, output video stage 1 feeds the cathode-ray tube over condenser 2 and includes a half-section, m-derived filter the shunt and series arms of which have tappings connected through double-pole switch 17. With the switch closed so that only part of each of inductances 13 and 16 is in circuit, the video pass-band extends up to 5 Mc./sec., and when the switch is open the range is reduced to 2.5 Mc./sec. The gain of the amplifier is approximately doubled when the pass-band is reduced. When the switch is closed the damping provided by the coupling to the shortcircuited portions of the inductances may be employed wholly or in part in place of damping resistors 11 and 15.

Title: Improvements in and relating to pulverising and grinding machines
IPC: B02C13/22
Filed: 1932-02-12
Abstract: 395,788. Impact pulverizers. COLLEY, L. ST. J., 70, Victoria Street, London. Feb. 12, 1932, No. 4226. [Class 59.] Animpact pulverizer comprises a rotor and one or more stator crowns having recesses from which backwardly inclined passages perforate the crown and form segregating means for the fines, the coarser particles returning from the recesses into the path of the rotor. The top portion of the casing may be eccentric to the rotor in order to decrease the velocity of the fines which pass out through backwardly inclined slots in the casing. The casing may be imperforate around the beaters and be provided with slots covered by screens outside the path of the beaters. As shown in Fig. 1, a rotating disc 1 is provided with integral front and rear projections 22 and removable front projections 26. The projections 22, Fig. 4, have a leading percussion face and may have abrading serrated side faces. The projections 22 engage between stator rings 9, 10 and 18, 19, the rings 9, 10, Fig. 2, being provided on the inward face with curved recesses 36 and on the outward face with serrations 42, the serrations and recesses being reversed on the rings 18, 19. The recesses 36 are perforated at 40 to permit the fines passing from one row of beaters to the other whilst the curvature of the recess is such as to throw heavier particles back into the path of the beaters. The lower part 44 of the peripheral casing, Fig. 2, is serrated whilst the upper part is provided with backwardly inclined recesses 47 which permit the fines to be blown therethrough by an air current, the casing being enlarged at 46 to reduce the velocity of the whirling particles. The fines passing through the perforations 47 are directed by the casing 13 to an outlet valve 48. The perforations may be made in a casing of pressed steel and a regulating plate having holes corresponding to those in the casing may be mounted slidably thereon to regulate the size of the perforations. In Fig. 1, the peripheral ring 12 is serrated and surrounds the beaters, the ground material being withdrawn through an axial orifice 31 by a fan 30. The fan 30 surrounds the rotor bearing 4 and air is drawn through a duct 35 to clear the space between these two members. Material from a hopper 25 is discharged by an air-tight feeder into a passage where it meets an ascending draught of air from an inlet 24 and is carried into the mill. Small metal objects are collected on a magnetic plate 28 whilst heavier particles fall into a pocket 29. The projections 22 may be provided on one side of the disc and the casing provided with a water-cooled passage, a screen which may have backwardly inclined apertures being placed either at the back of the disc or made to form an extension of the peripheral ring 12. A separate fan may be used to carry off the fines or they may fall by gravity through a discharge orifice such as 15 in Fig. 1. Oversize particles may be returned from the screen to the beaters.

Filed: 1951-02-21
Abstract: 710,346. Fluid-pressure servomotor-control systems. ROBERTSHAW-FULTON CONTROLS CO. Feb. 21, 1951, No. 4255/51. Class 135. [Also in Group XI] In a control apparatus, applicable to fluid fuel burning appliances a diaphragm valve is operated by the supply or exhaust of pressure fluid to or from a valve chamber under the control of three valves and two valve operating means. With the diaphragm valve 20 closed, on pressing a button 96 the normally closed contact 106 controlling a solenoid 118 is broken and a contact 108 made to enable the mains L1, L2, to energize an igniter 46 through a transformer 48, and the valve seats 64, 78, are opened by the button through a rod 102 carried by an armature 90 engaging the valves. Gas passes from a pipe 42, passage 150, seat 64 and pipe 34 to a pilot burner 30 which is ignited and heats a thermocouple 84 which energizes an electromagnet 86 to hold the armature 90 in its depressed position, in which position the valve opening the seat 64 closes a seat 66 and a gas passage 152 leading from the passage 150 to the diaphragm chamber 28. The valve for the seat 78 and a valve for a seat 112 actuated by a lever 116 attracted by the solenoid 118 controlled by a room thermostat 50, together control the exhaust of gas from the chamber 28 via passage 148, seats 112, 78, and pipe 36 to a bleed burner 32 for allowing gas pressure in the fuel inlet pipe 12 to open the diaphragm valve. The latter closes if the pilot burner fails and allows fluid pressure from passage 150 to enter the diaphragm chamber via seat 66 and opens and closes under the control of the thermostat 50, and the valve for the seat 112 and seat 114 leading to passage 150. Should the mains supply fail, the valve for the seats 112, 114 has means 126, 128, 142 whereby it may be manually operated but returns to thermostatic control on resumption of the supply. The main fuel inlet cock 14 and the pilot fuel cock 44 may be interlocked.

Filed: 1925-02-16
Abstract: 229,351. Two-Tone Corporation, (Assignees of Mijer, P.). Feb. 14, 1924, [Convention date]. Coating-machines.-A process of coating textile fabrics and other articles consists in atomizing the coating matter in a gaseous medium and in conveying the medium with the coating matter away from its origin to a sufficient extent to eliminate drops and to expand the pressure of the medium, and not till then causing the resultant cloud of coating medium to make contact with the fabric or other article. In the arrangement shown, the material to be treated,. for example, a silk fabric 12, is secured to a table 11 above the level of the floor of a chamber 13, and to the side of the table 11, but separated from it by a partition 17, is placed a spray-producer such as an air-brush 14, the spray from which is directed horizontally; the spray is directed upwardly by deflectors 24 and passes over the partition 17 in the form of a cloud of fine particles since all the larger droplets have fallen into an elongated trough 19 arranged beneath the spray-producer 14. The cloud descends on to the material 12, being guided by deflectors 21 arranged at the corners of the chamber 13. Pattern enecte are produced by means of a stencil 16 placed on the material.

Abstract: 581,776. Automatic control systemsfor ships. BELL, J., BOLSHAW, S., and WRIGHT, C. S. March 18, 1943, No. 4384. [Class 38 (iv)] Steering ; altitude. Ship stabilising means for pitch roll or yaw is operated by a power followup motor controlled by the receiver of a system for the transmission of angular data to which is transmitted an impulse representing the sum of data proportional to the angular velocity and angular displacement of the ship about the appropriate axis at least one of which is adjustable in amount and sense. Control devices of suitable character such as gyroscopes are coupled to means for transmitting the angular data secured. As shown a gyroscope 1 is arranged to be responsive to angular velocity of roll, for example, and a gyroscope 6 to be responsive to displacement in roll. Control impulses in opposite senses and of different values for the same displacement are derived from the gyroscope 6 by connections 12, 13 to elements of transmitters 10, 11 which also receive velocity impulses from the gyroscope 1 and the combined impulses are transmitted to the contacts of a switch 17 which has an off position and positions selecting either of the combinations of impulses for transmission to receivers controlling the roll stabilizer motors 16p, 16s. Preferably a further switch 18 provides selection whereby the impulses may be employed for stabilization or maintenance of roll. To produce rolling in a calm a third position of the switch 18 connects to a switch 19 which is operable by hand to apply power to the stabilizers in a manner to establish rolling. Fig. 2 shows a system whereby control devices responsive to roll and to pitch and comprising the features set forth may be combined to control jointly stabilizing means operative in respect of pitching and rolling. Electrical or mechanical-differentials 20 effect the combination of both types of control impulses derived from roll and pitch systems 23, 24 and transmit them with appropriate reversal, where required, to the stabilizers 15.
