Title: Improvements in or relating to fluid meters
IPC: G01F3/18
Filed: 1944-05-11
Abstract: 582,745. Liquid meters. BECK & CO., Ltd., and SOAR, H. G. May 11, 1944, No. 8999. [Class 69 (ii)] In a fluid meter comprising two spaced pairs of interconnected pistons 4, 4a and 5, 5a, Fig. 3, working in cylinders 7, 7a and 8, 8a, a rotary cylindrical valve 11 located between the pairs of cylinders and coupled to the piston-rods 6, 6a is actuated at the required times to admit fluid to one cylinder, e.g. of a pair, to the outer side of the piston 4, and to the other cylinder 7a on the inner side of the piston 4a, and is also actuated to discharge fluid from one cylinder 8 of the other pair on the outer side of the piston 5 and from the cylinder 8a of the second pair on the inner side of the piston 5a so that each pair of pistons cause four displacements of the cylinders for each revolution of the valve. Chambers 9, 9a provide communication between the outer and inner sides of the pistons 4, 4a and 5, 5a respectively, and chambers 10, 10a connect the inner and outer sides of pistons 4, 4a and 5, 5a respectively. Members 12, 12a are cross-over ports connecting valve ports 14, 14b with the chambers 10, 10a respectively. The valve 11 which is geared to a suitable indicating mechanism rotates within a casing 13, Fig. 1, and is geared to the piston-rods 6, 6a through gearing 15, which latter meshes with gears 16, 17 on shafts 18 of crank assemblies, the lower end 19 of which form crank housings 19a for driving arms 20. Each crank housing 19a is arranged accentrically to the shaft 18 to afford stroke variation. The gearing is arranged so that when one pair of pistons is at the end of the stroke the other is at the centre. In operation, when fluid from the meter inlet 2 passes through the valve 11 and port 14 to the crossover port 12 and thence to the space 10 to the appropriate sides of the pistons 4, 4a, at the same time fluid is discharged from the other sides of the pistons 4, 4a by space 9, a port 14a to the meter outlet. Similarly, whilst fluid is being discharged from the space 9a in communication with the other pair of pistons, by way of a port 14c, fluid enters the space 10a by way of port 14b and cross-over port 12a.

Filed: 1932-03-30
Abstract: 398,917. Reciprocating motors. HOPEWELL, F. B., 301, Waverly Avenue, Newton, Massachusetts, U.S.A. March 30, 1932, No. 9198. Convention date, April 16, 1931. [Class 35.] Electromagnetic mechanism for propelling a body into space, e.g. the shuttle of a loom, consists of two cores with opposed faces and windings arranged to produce a travelling magnetic field when energized by a polyphase or like current, the body to be propelled including a conducting portion moving between the cores. The invention -is shown applied to a loom. Cores 10, 11 are supported on the lay 1 and provided with coils 13 constituting windings 61, 63, 65, 67, 68, 69 arranged symmetrically on the lower cores as shown in Fig. 4. The shuttle is provided with a fin 14 of aluminium extending between and beyond the cores 10, 11, so that the shuttle is impelled by the travelling field acting on the eddycurrents produced in the fin. The cores 10, 11 extend longitudinally beyond the coils 13, as shown in Fig. 1, so as to lessen distortion of the paths of the flux at the end coils. The coils 61, 63, 65 are connected in star, the coil 63 being connected in the reverse direction to the other two, and they can be connected to a source of three-phase current through a switch 71 actuated by cams driven from the loom drive. When the shuttle has been ejected from one shuttle-box and enters the other its motion is checked by direct or singlephase current -passed to the coils of the second box bv switches 74. When it has stopped, three-phase current is passed to the coils of the second box by a switch 78 and continuous current to the coils of the first box by a switch 80. An alternative arrangement of cores and shuttle is shown in Fig. 7. The cores 85, 86 are placed on opposite sides of the shuttle and the bottom of the shuttle is formed of a plate 87 of magnetic material 87 between conducting plates 89, 90 connected by conductors 88. The magnetic plates and conductors may be arranged in the sides of the shuttle instead of the bottom. An arrangement of two shuttle-boxes traversed by the flux in series is described. The shuttle instead of moving freely may be carried on a rocking arm.

Title: Improved Apparatus for Indicating and/or Recording Quantities of Carbon Monoxide in Hydrogen or Gases Containing the same applicable also for like purposes.
Inventor: RIDEAL ERIC KEIGHTLEY
IPC: G01N27/00
Filed: 1918-06-04
Abstract: 134,243. Rideal, E. K., and Taylor, H. S. June 4, 1918. Gas analysis.-The amount of carbon monoxide present in hydrogen, or in the atmosphere of coal mines &c., is measured by causing it to combine with added oxygen to form carbon dioxide by passage over a a catalyst, absorbing the carbon dioxide in lime-water, and measuring the amount absorbed by the variation in the electrical conductivity of the lime-water. The oxygen may be supplied by adding air, or the mixture of hydrogen and oxygen obtained from an electrolytic cell. The gas to be tested, freed from carbon dioxide and sulphuretted hydrogen by passage through caustic soda solution or otherwise, is passed through a meter d, electrolytic gas from a cell e is added, and the mixture passed through a chamber a containing iron-chromium-cerium oxide catalyst maintained at 200-250‹ C. by an electric heating-coil b. The gas is passed through a spiral bubbler or a glass-wool column g, down which lime-water flows at a regulated speed, and from which it passes to a cell h, in which its conductivity is measured. The variation in conductivity may be recorded by an instrument i. The apparatus may be used to measure the amount of any constituent of a gas which, by fractional combustion with added air or oxygen, will yield a gas which can be absorbed by a liquid, the conductivity of which varies with the amount of absorbed gas.

Title: Improvements in means for automatically stopping or controlling phonographs
IPC: G11B17/02
Filed: 1929-03-22
Abstract: 334,562. Stockton, J. P. March 22, 1929. Starting and stopping.-Relates to means for automatically stopping or controlling gramophones, of the kind in which a lever driven from the tone-arm and a lever driven by the motor have a differential movement when the tone-arm changes its motion at the end of playing, such movement being utilized through trigger mechanism to apply a brake to the turntable, or to open a switch controlling the driving motor, or to initiate the action of repeat or record-changing mechanism. According to the invention, the trigger mechanism is carried by the motor-driven Lever and is released upon the sudden inward movement of the tone-arm which results when the stylus passes into the usual concentric or eccentric terminal groove. Figure 2 shows a lever 20 movable about a pivot 21 by a pin 17 on the tone-arm and a lever 25 mounted on a pivot 26 on the lever 20 so that relative movement of the levers can take place when the switch or brake is to be actuated to stop the machine. The lever 25 has pivoted thereto a trigger-lever 31 and a switch or brake-operating lever 30, a pin 36 on the lever 31 holding the lever 30 in the off position against the action of a, spring 43. The lever 30 also carries a toothed member 41 which, towards theend of the pla.ying movement, engages the motor-driven worm 42 to ensure synchronous movements of the levers 20, 25. When the movement of the tone-arm accelerates at the end of the playing movement due to the needle entering a special guiding groove, the end 34 of the lever 20 engages the end 33 of the lever 31 to release the lever 30 and, in the example shown, cause the insulating member 53 to pass between the spring contacts 47 and break the circuit of the driving-motor. Stopping can be effected independently of the special groove by the engagement of a pin 61 on the lever 31 with a fixed cam 60. The parts are reset by the return of the tone-arm, the trigger 31 beinp re-engaged with the lever 30 when a link 53 engages a fixed stop 58. A hand-operated rod (not shown) may engage the pin 54 to stop the motor at any time. The same mechanism can be employed to close a switch through an auxiliary motor to operate, for example, a record-changing mechanism. Fig. 11 shows means whereby the lever 30 operates to lift a lever 70, trip a lever 81, and release a spring- controlled lever 77 which serves to actuate the brake-lever 73.

Title: Improvements in the purification of acetylene
IPC: C07C7/09
Filed: 1931-03-27
Abstract: <PICT:0371142/IV/1> Acetylene obtained by the thermal or electrical treatment of hydrocarbon products of any kind is freed from impurities such as diacetylene, allylene, allene, butadiene, and hydrocyanic acid by cooling to a temperature below -20 DEG  C. under such conditions that solidification or condensation of acetylene is avoided.  The cooling may be effected in stages and under atmospheric or raised pressure.  The crude acetylene may be mixed with the vapour of a solvent such as methanol, in order to avoid separation of frozen impurities.  As shown, crude acetylene supplied through a pipe 6 passes through a vessel 7 containing methanol and then up a bundle of tubes 1 immersed in methanol, in which the gas is cooled, e.g. to -30 DEG  C., by expanding liquid ammonia in a coil 9.  The condensate comprising moisture and methanol, with or without residual solvent from the isolation of the crude acetylene, is withdrawn at 10.  The gas passes through a pipe 11 up a second tube bundle 2 in which it is cooled, e.g. to -75 DEG  C., by expanding liquid ethylene in a coil 13.  The condensed impurities are withdrawn at 15.  The ethylene used in the coil 13 may be liquefied in a coil 14 in the methanol surrounding the tubes 1.  The purified acetylene passes out at 16, and may be freed from traces of impurities by means of an adsorbent such as silica gel, or used directly for the manufacture of acetaldehyde. Examples are given of the treatment of gases containing 89 and 9 per cent of acetylene respectively; in the first example, the gas is cooled to -30 DEG  C. and then to -70 DEG  C. under atmospheric pressure; in the second example, the gas is cooled directly to -70 DEG  C. under 25 atmospheres pressure.

Title: Improvements to fastening devices such as locks or latches for doors, windows or thelike
IPC: E05C1/14
Filed: 1962-03-12
Abstract: 983,314. Lockable latch bolts. D. E. C. WEBSTER. March 12, 1962 [March 20, 1961], No. 9409/62. Heading E2A. The Specification relates to a lockable latch bolt device of the kind described in Specification 885,378, but the invention is directed to a modification of the means for locking the bolt. The slide 13 which causes the bolt 2 to be withdrawn has a locking rod 18 passing along the axis of said slide as in the prior Specification, but in the present Specification locks the slide against movement by means of abutments on the rod which, when said rod 18 is rotated, engage either the outside or the inside of the casing 8 in which the bolt moves. The construction differs from the prior specification inasmuch as the non-rotating fixed handles 25, Figs. 21 and 22, are arranged vertically and are secured by bolts 46 which pass through one handle 25, Fig. 1, the door 5, the bolt casing 8 and into tapped holes in the other handle 25, one of the bolts passing between the two legs comprising the bolt 2. The bolt 2 is retracted by finger pressure on one or other end of the slide 13 whereby one or other of the sloping surfaces 10 engage the ends 7 of the bolt prongs 6. Locking is effected by blocking the movement of the slide 13 by rotating the rod 18 passing through the axis of the said slide. In one embodiment a tongue 20e, Fig. 20, is swung upwardly within the casing 8 to prevent its end-on movement in either direction to withdraw the bolt. In another embodiment a tongue 20a, Fig. 16, is swung upwardly to a position outside the casing 8, Fig. 17, to prevent movement in one direction only, so that the latch bolt can be withdrawn by operation from one side of the door only. A more secure locking is effected by having an additional tongue 20b, diametrically opposite to tongue 20a. The rod 18 may have a pair of tongues 20, Fig. 6, which engage the inside walls of casing 8 to prevent movement. By such means, or by a central wider tongue, the bolt may be held in either a withdrawn or extended position. To prevent free rotation of the rod 18 in its operative position a pair of flat surfaces 32, Fig. 6 and 17, are provided which are engaged by a leaf spring 33 located in a recess 30 in the slide 13. Fig. 3 shows means whereby the slide 13 may be locked against movement by a sliding clip 57 which may be moved into a groove 66 in the push button 35 on one side of the door. The rod 18 may be locked against rotation by a cylinder lock 23 or locks, Fig. 7, arranged on one or both sides of the door.

Abstract: 719,415. Delivery stop-motion for spinning machines. HARBECK, M.. STEFFEN, H., HARBECK, M., and STEFFEN, E., [trading as HEIDENREICH & HARBECK]. April 16, 1952, No. 9484/52. Class 120(2) A stop-motion, particularly for a jute spinning machine in which, the supply of material is interrupted upon breakage of the thread, has a detent ring controlled by a thread feeler and a feed roller loosely mounted on a driving shaft, the coupling or uncoupling of the shaft and roller being caused by oppositely directed relative movements between the detent ring and the feed roller, an intermediate member normally embracing the driving shaft and being rigidly connected to the feed roller and to the detent ring so as to contract into frictional engagement with the driving shaft when the feed roller lags behind the detent ring. Two mirror-image feed rollers 2, 3 may be mounted for rotation about a driving shaft 1. Each roller is connected with a detent ring 4, 5 having detents 15 by a spring 11, 6. Under normal conditions, the feed rollers 2, 3 are frictionally driven by the shaft 1 and rotate the detent rings 4, 5 through the springs 11, 6 thus causing the springs to contract and grip the shaft 1. When a thread breaks, a lever 16 is tripped by the thread feeler into the path of the detents 15, thereby stopping the appropriate detent ring, causing the attached spring to expand and release its grip on the shaft 1, whereupon the feed roller ceases rotation. If the power transmitted becomes too large, the springs break and damage to other parts of the machine is prevented. Instead of the helical springs, spiral clock springs may be employed.
