Title: Improvements in or relating to fitting sole heel seats for the reception of heels and machines therefor
IPC: A43D35/00
Filed: 1924-05-16
Abstract: 238,499. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). May 16, 1924. Cutting. - Relates to machines of the kind described in Specifications 145,847 and 185,739, for bevelling the margin of the heel seat of a sole, and consists in the provision of cutting means gashing the supported work by a movement widthwise across the sole face, to form a stunted heel breast locating tongue 362, Fig. 6, on the sole, and a bevel on the heel seat at the heel breast location. As applied to a known machine wherein the last is supported by a pin 42, Fig. 1, and the rear sole margin supported by crease plates 62 closed about the shoe by a handle. 94, the knife is mounted on a bar 172 slid longitudinally for the cut by a bell-crank lever 180 connected by a link 184 with a treadle. To adjust the position of the cut, the guide 176 for the bar may be moved forwardly or rearwardly by a graduated dial 266. The knife 170, Figs. 3 and 4, has the front and one longitudinal edge sharpened, and a guard plate 240 the forward edge of which serves as a plough to lift the tongue during the cut. A presser foot in advance of the knife is constituted by a tapered roll 244 mounted on a plate 246 hinged to a second pivoted plate 248 which may be raised or lowered by a milled head 252. A bar 210 is carried by the guide 176, so that adjustment of this guide by the dial 266 limits the forward movement of the margin bevelling means to correspond with the position at which the tongue 362 is formed.

Title: Improvements in hydraulically operated presses
IPC: B30B15/16
Filed: 1941-11-28
Abstract: 547,654. Hydraulic presses. VICKERS, Inc. Nov. 28, 1941, No. 15322. Convention date, Oct. 14, 1940. [Class 69 (ii)] A hydraulic press is constructed with a pre-fill valve 22 forming part of a unitary self-contained assembly to provide for pre-fill valve operation and to control the application of pressure to the main ram 12. The platen 10 of the press is advanced to working position by the aid of booster cylinders 20 with pistons 18 connected by rods 16 to the platen, and the pistons also act to return the platen. The operating liquid is supplied by a pump 26 driven by a motor 28, and an auxiliary pump 68 supplies liquid for actuating control valves 80, 56, which are also capable of actuation by electromagnets 82, 60, 58 under control of switches 184, 196, 192 and 194, of which the latter is a limit switch which is opened when the platen 10 has returned to its upper position and causes the pressure liquid to be byepassed to tank. On operation of the starting switch 184 the solenoids 60, 82 are energized, and as soon as the platen 10 starts downwardly switch 194 closes and holds the solenoid 82 energized. Release of switch 184 de-energizes solenoid 60 without shifting valve 56. The moving of valves 56, 88 to the right causes operation of a four-way valve 34 to the right and the liquid from pump 26 passes via pipe 40 to the cylinders 20, and also to a port 44 of the pre-fill valve. The actual pre-fill valve 124, Fig. 2, is open while the platen descends under the action of the pistons 18. The discharge from cylinders 20 passes to the tank 24 via a valve 48 which opens under pressure. When the platen meets the work the pressure builds up in the cylinders 20 and in port 44. At a particular pressure a valve 148 of the kind described in Specification 393,761, opens to admit pressure to a recess 132 of the pre-fill valve and so a piston 138 is moved to the right to close the valve 124 and cut off connection with the tank, and also to open connection between recesses 132, 134 of the valve. Pressure liquid now flows to the main cylinder 14 through passage 166 and port 114, and also passes to valve 48 so as to open this valve further and so reduce the resistance to the return liquid. At the completion of the operation stored up energy is released gradually by bleeding the pressure liquid from cylinder 14 through port 114, passage 166, recesses 134, 132, cheek valve 162, Fig. 3, restrictor 164, chamber 146, port 44 and thence to the left-hand cylinder port of valve 34, and tank conduit 36. The returning liquid also acts upon the small area of piston 138 tending to open the valve 124, but this can only take place when the pressure on the large area of the piston is reduced to a fraction of that on the small area. When this occurs the valve 124 opens. Finally the limit switch 194 is operated to de-energize the solenoid 82 and the parts then return to normal inoperative. position. An indicator 144 is fitted to the spindle of the pre-fill valve to indicate the extent of opening.

Title: Improvements in or relating to the separation of suspended particles from vapors or gases
IPC: B03C3/013
Filed: 1943-09-21
Abstract: <PICT:0583176/III/1> In processes using a fluidised catalyst, such as in the cracking of oils, the regenerated catalyst is recovered from the effluent gases by an electrostatic separation process, in which ammonia is added to the gases to aid the separation.  The plant to which the invention is applied is shown in the drawing.  The oil vapours and a fluidised catalyst, consisting principally of silica and alumina enters the cracking chamber 1 by way of the pipe 2 and heater 12. At the top and outlet of this chamber centrifugal separators 3, 5 remove most of the solids from the gas stream, which is passed to a condenser 7 and separation drum 8 from which the permanent gas is taken off by a pipe 9 and the distillate by a pipe 10.  The fluidised solid is withdrawn from the bottom of the chamber 1 by a pipe 11, and a portion which contains a rather large portion of spent catalyst coated with carbon is fed by way of a cooling coil 16 to a regenerator 15, to which air or other regenerating gas is delivered by a pipe 20.  Most of the regenerated catalyst is separated by centrifugal separators 21, 22 and returned to the cracking chamber by way of the pipe 18.  The effluent gas carrying the residue of catalyst is delivered to an electrostatic separator 23, and the deposit delivered separately or to the main stream. Ammonia is fed in small quantities to the separator by a pipe 24 or introduced in any other convenient manner.

Title: Improvements in or relating to apparatus for measuring or controlling the rate of flow of a fluid
IPC: G01F15/06
Filed: 1948-06-10
Abstract: 679,363. Electric indicating systems; mechanical follow-up systems. LINDARS, H. June 10, 1949. [June 10, 1948] No. 15727/48 Classes 40 (i) and 118 (ii). [Also in Groups XXIX and XXXV] A fluid flowmeter for measuring or controlling the rate of flow of a fluid comprises a metering device 1 of known kind connected in the fluid circuit 2, 3, a differential gear 16 having a first element 15 driven from the metering device, a secured element 17 driven at a controlled speed by a time base circuit 26, and a third element 20, the speed of which is the difference between the speeds of the first and second elements, and which operates measuring and/or controlling mechanism. For a predetermined rate of fluid flow through the meter 1, a cam disc 6 having a number of lobes 7 is driven at a speed proportional to the rate of flow. The lobes 7 co-operate with a resilient contact 8 and a fixed contact 9 causing electric impulses from a battery 11 to be applied to the energizing winding 12 of a step by step mechanism 13 which rotates the element 15 at a speed proportional to the rate of fluid flow. The second element 17 is driven at the same speed in a reverse direction by a second step by step mechanism 19 under the control of the time base circuit 26. The third element 20 thus remains stationary as long as the fluid flow remains at the predetermined value. Upon departure from this value the element 15 will rotate at a different speed to the element 17 so that the third element 20 will rotate and operate, through suitable gearing, a pointer 30 indicating rate of fluid flow and the moving arm 28 of a potentiometer 27 in the time base circuit 26. Adjustment of the potentiometer 27 alters the frequency of the time base circuit so as to bring the speed of the element 17 to that of the element 15, rotation of the element 20 then ceasing. The gearing on the element 20 may also operate central mechanism as described in Specification 582,094 to restore the fluid flow to the predetermined value. A counter 34 attached to the element 15 indicates the total volume of fluid passing through the meter 1. In a modification the time base circuit may be replaced by a mechanically driven impulsing circuit such as a synchronous motor driving a make and break contact device through a variable speed gear whose ratio is controlled by the gear 16.

Title: Stop motion devices for power-driven machines
IPC: D05B69/22
Filed: 1928-05-30
Abstract: 309,771. Fair-weather, W., (Singer Manufacturing Co.). May 30, 1928. Buttonhole sewing-machines; stopping gear.- A stop-motion device for a machine comprises a wheel geared to the driving shaft and normally running idly at a speed less than that of the shaft, and stopped at a certain point of the machine cycle by a spring plunger, to stop the rotation of the driving shaft. The invention is illustrated as applied to a buttonhole sewing-machine. At a given point in the machine cycle, e.g. when each buttonhole is completed, a lug 49 on the cycle cam 50 trips an adjustable stop 48 on a lever 43 to withdraw a pin from a notch 44 in an arm 45 pivoted at 46 to the stop,-lever 47, 38. This lever then swings from the inoperative position, shown in dotted lines in Fig. 1, to the operative position, shown in full lines, when a spring plunger 41 carried by it comes into the-path of a cam 24 on the member 23 carried within the gear 21 which meshes with the pinion 13 on the driving shaft 9. The plunger rides up the cam 24 and engages the recess 25, bringing the gears 21, 13 to rest. The stopping shock is absorbed by the buffering springs 31 in the usual way. The gears are in the ratio 2 : 1 so that the stopping gear 21 rotates at half the speed of the driving shaft. The stop-lever 38 carries an arm 39 provided with a belt-shift 40 which transfers the belt from the fixed pulley 10 to the loose pulley 11 at the time of stopping the machine. The work clamp 50<1> is operated from the driving shaft 9 through gears 73, 72, 71, 70 and shaft 64 and gears 65, 66, 67 in the usual way. The cutter 6<1> is operated from the stop-lever 38 by a bar 52, fixed to the plunger 41 by a screw 51, carrying a roller 53 engaging a notch in the lever 55. This lever is connected to the cutter by links 57, 58, 59. The link 57 has pivoted thereto a latch 61 with a shoulder 62 engaging under the pin 63 on the lever 58. The cutter is prevented from actuation by the stopping device by moving the latch from under the pin 63.
