Title: Improved air, gas or like fluid compressor
IPC: F04F5/54
Filed: 1951-07-16
Abstract: 693,871. Centrifugal pumps. PIENAAR, T. M. S. July 16, 1951 [July 31, 1950], No. 16854/51. Class 110(i) [Also in Group XXVIII] Means for compressing gas comprises an injector 9 disposed in a closed liquid circuit which entrains gas through a pipe 10 and forces it with the liquid through pipes 7, 6, a circulating pump 2 and a pipe 3 into a single pressure tank 1, where the gas separates from and is compressed in the space above the liquid and forces it through a pipe 8 to the injector. A baffle 21 assists the separation. The injector has an axial convergent-divergent liquid nozzle which is adjustable axially by a rod 26. A foot-valve 25 is fitted to the pipe 10. The gas is delivered through a filter 17 to a valved pipe 19; a safety valve 20 and pressure gauge 18 are fitted. The pump which may be a gear pump or a multi-stage centrifugal pump is driven by an electric motor 15 controlled by a pressure switch 16. Liquid leaking past the pump bearing glands passes through a tube 24 to a container 23 surrounding the gas intake from which it is drawn back into the liquid circuit. Two or more pumps may be used. In another embodiment Fig. 2, a plurality of parallel injectors 7a, which are supplied with liquid from the tank 1 through a pipe 8a, entrain the air through valved inlets 33 and deliver it through a venturi 6, pump 2, and venturi 3a to the tank. Baffles 30 assist gas to separate from the liquid, the latter being circulated by a pump 29 through a cooler 28. When the pressure in the tank exceeds a given value a one-way pressure valve 36 opens communication between the tank 1 and the common delivery manifold 32 of the injectors whereby the back pressure through the latter stops the flow and the pump is caused to run under " no-load conditions; Various types of combining cones are described and where space is limited the combining cones may be in the form of one or more helical convolutions. The air may be introduced into the injector under pressure by means of a supercharger and a cooler and a venturi tube may be disposed between the supercharger and the injector.

Title: Improvements in or relating to automatic temperature control apparatus
IPC: G05D23/12
Filed: 1958-05-28
Abstract: 869,795. Thermal switches. SOPAC REGULATION. May 28, 1958 [May 29, 1957], No. 17093/58. Class 38 (5). [Also in Group XIII] Of switch contacts 45, 46 controlling the heating or cooling of a medium used to heat or cool a space, e.g. in a building or train, contact 46 on a lever 47 having a pivot 48 is moved by bellows 4 and 10 operating in tandem on the lever and responding respectively to the temperature of the air outside the space and to the temperature of the medium, while contact 45 is moved by bellows 19 responsive to the speed of the wind outside the space since its pilot bulb 15 is adjacent an electric heater 16. The magnitude of the movement of the contact 45 is controlled by the position of a pair of rollers 29, 31, Fig. 2, along spring-loaded levers 26, 41 pivoted respectively at 27 and 42, Figs. 1, 3. The rollers 29, 31 are independently journalled on a spindle mounted on an arm 32 pivoted at 33 on one end of an L- shaped lever 34 which is adjustable sideways with respect to its pivot 35 and loaded by a spring 37 so that a knife edge at the other end rests adjustably on a shoulder 6 of the rod 5 of the bellows 4. Wind-cooling causes lowering, Fig. 3, of a lever 21 and its adjustable stud 23 and in turn levers 26 and 41 and contact 45 are lowered so that the contacts 45, 46 meet, that is if the pivot 27 and the spindle of the rollers 29, 31 are not aligned as in Fig. 1. The apparatus is adjusted to give the position of Fig. 1 (to give no contact movement with wind change) when the temperatures inside and outside the space are equal. This adjustment is made by raising or lowering the pivot 35 of L-lever 34 by means of a knob 38 by which a plate 49 bearing the pivot 35 and the pivot 48 is raised or lowered. The position of the rollers 29, 31 and therefore the magnitude of the movement of the contact 45 is controlled automatically by the movement of the shoulder 6 associated with the bellows 4 when the inside and outside temperatures differ. Should the temperature of the heated space become excessive, the bellows 10 responding to the temperature of the heating medium raises an adjustable arm 52 to open a switch 51 and thus stop forced circulation of the medium. The switch 51 does not operate under normal conditions.

Title: Improvements in and relating to a method and machine for finishing gear wheels
IPC: B23F19/06
Filed: 1944-09-07
Abstract: 587,133. Gear - cutting. NATIONAL BROACH & MACHINE CO. Sept. 7, 1944, No. 17124. Convention date, Jan. 10. [Class 83 (iii)] In a process and machine for finishing toothed gears by means of an intermeshing toothed cutter producing a shaving action, the work and cutter rotate on crossed axes and have relative axial reciprocation and they are fed towards each other only at one end of the reciprocations. The work 2, Fig. 2, consisting of a blank roughed out by bobbing or shaping, is mounted on a table 1 which is reciprocated axially by the end 8 of a lever 6 pivoted at 7 and rocked by an eccentric 11 on a shaft 19 driven by gearing 21 from an electric motor 22. The cutter 4 is carried by a head 3 and is rotated about an axis inclined to the work axis at an angle of from 3 to 30 degrees by means of gearing driven by a reversible electric motor 23. A cam 17 is driven by gearing from the shaft 19 and acts on a lever 12 to feed the head 3 downwards, against the pressure of a spring 18, after each double reciprocation of the work, and simultaneously a limit switch is operated by the lever 6 to reverse the direction of rotation of the cutter motor 23. The cam 17 may have any number of steps for feeding the head, two being shown at 31 and 51, the remainder of the cam consisting of concentric portions which maintain the axis of the cutter and work at a fixed distance apart so that the reciprocations of the work during these periods will produce idle finishing strokes. The application of the invention to a shrouded gear and to a narrow gear is described. In a modified machine, which is similar to that described in Specification 474,227, the cutter 52, Fig. 14, is carried by a head 51 and the work 50 is mounted on a table 49 reciprocated rapidly by an electric motor 53, screw 540 and gearing 54. The motor 53 is reversed by a limit switch 670 and dogs 680 on the table. Vertical feed is imparted to the table at one end of the reciprocations by means of an electric motor 58 which rotates the feed screw 55 through a shaft 66, worm 65, cam 57, lever 62, pawl 61, ratchet 59 and bevel gears 63. The motor 58 is started by a limit switch 67 actuated by a dog 68 on the table and is stopped by a switch 69 actuated by a cam 70 rotated in synchronism with the cam 57. The limit switch 67 also reverses the motor which drives the cutter 52, simultaneously with the application of vertical feed.

Abstract: 958,200. Making grids for electron tubes; coiling. WESTINGHOUSE ELECTRIC CORPORATION. May 2, 1963 [May 23, 1962], No. 17406/63. Heading B3E. A method of winding grid wire about spaced grid support rods comprises rotating said support rods about an axis parallel to the support rods, simultaneously moving longitudinally said support rods at a uniform rate in the direction of said axis of rotation, feeding grid wire to said support rods by means of a guide member while rotational and longitudinal movement of said support rods is in progress, and moving said guide member relative to said support rods in a direction parallel to said axis of rotation for varying the spacing of successive grid wire turns to be wound upon the support rods. A draw bar 10 rotated by means 12 and moved axially at a uniform rate by a lead screw 26 has clamped at 14 thereto a pair of grid support rods 23, 24 spaced by cross-members 25. Grid wire 31 is directed on to the grid rods 23, 24 by a guide 70 carried by a block 66. In order to vary the spacing of the turns of wire 31 wound on the rods 23, 24 the block 66 is moved parallel to the axis of rotation of the rods 23, 24 by a cam disc 43 having a circle of axially adjustable studs 44 thereon. The studs 44 protrude differing distances and engage a follower 46, on an arm 50 pivoted at 53 and linked at 58 to the block 66, to move the block when the disc 43 is rotated. The disc 43 is rotated by a ratchet 69 driven by a pair of pawl arms 74 and 76 actuated by eccentrics 78, 80 on a shaft 81 rotated at the same speed as the draw bar 10. The pawl arms 74, 76 are in turn brought into and out of driving engagement with the ratchet 69, so that the disc 43 is rotated only when it is desired to change the spacing of the grid turns, by springs 75, 77 whose action is opposed by a lever 82 rocked by a cam 94 which makes one revolution for each grid wound. A solenoid 100 also acts to rock the lever 82. The cam 94 may comprise two adjustable discs 95, 97.

Abstract: 360,824. Typewriters &c. ACCOUNTING & TABULATING MACHINE CORPORATION, 374, Broadway, New York, U.S.A. June 5, 1930, No. 17453. Convention date, June 17, 1929. [Class 100 (iv).] Platen-rotation for blanking ; line-spacing mechanism.-The paper-feeding means of a tabulating- machine is associated with a device, additional to the line-spacing mechanism, for automatically imparting blank-feed after the total is printed. The machine shown in the Figure comprises adding- racks 17, type-carriers 18, and hammers having triggers releasable by means of the type-carriers, a locking-bail for the hammers being releasable by means of a pushbutton 40 or the total-control shaft 43. The bail is carried by a shaft 36 having an arm 37 engaging a lever 39 which is rocked by the pushbutton or by an arm 48 on a link 47 connected to the shaft 43. A ratchet wheel 51 on the shaft 50 of the platen 32 co-operates with a line-spacing pawl 52 on a bell crank 53 which is actuated by an adjustable pin 55 on a link 56 and is returned by a spring 54. The link 56 is connected to rocking plates 57, 91, the plate 57 being actuated by a spring 61, and an arm 60 on the main adding-shaft 10. The link 56 is normally disabled by means of a flange 80 which obstructs a rocking arm 84 connected to the plate 57. The flange is formed on a slide 81 which is connected to an arm 83 on the shaft 36 and is depressed to release the arm 84 when the hammer-bail is released. A stop 87 on a slide 88 limits movement of the arm 84 when released. The movements of the pawl 52 are limited for double and single line-spacing by contact of lugs 65, 67 on the bell crank 53 with stops 66, 68 respectively. The stop 68 is formed on a bar 69 connected by a bell crank 71 and link 75 to a pin 76 on the slide 88, the shaft 43 having a finger 77 engaging the pin. Before a total is printed, the slide is depressed, the bar 69 is retracted, and double line-spacing is effected. The plate 91 carries a blanking-pawl 95 co-operating with a ratchet disc 94 geared to the platen shaft. At each item-printing operation, the pawl 52 effects line-spacing, the ratchet disc 94 is advanced, and the pawl 95 moves idly. At the total-printing operation, the slide 88 is depressed to permit of double line-spacing, and the stop 87 is moved out of the path of the arm 84. The link 56 is thereby permitted to make an abnormal movement, and the pawl 95 is enabled after varying lost-motion to engage one of the teeth and turn the ratchet disc to effect blank-feed, the feed being determined by the lost-motion. The pawl 95 can be turned on to a stop 99 to silence the blanking- mechanism, and the line-spacing and blanking- mechanisms can be silenced by moving a fingerlever 100 into engagement with a stop 101 on the ratchet disc. The bar 69 is secured to the bell crank 71 by a screw 70 passing through a slot 72, the arrangement enabling the bar to be set in retracted position when double-line spacing is required for the items.

Filed: 1935-06-18
Abstract: 458,132. Master control of motors. MALEY, A. W., 4, Grosvenor Road, Handsworth, and TAUNTON, E. M., 90, Fitz Roy Avenue, Harborne, both in Birmingham. June 18, 1935, No. 17519. [Class 38 (iii)] In a control system for series motors including contactors for effecting the speed control, the windings of the contactors are connected in turn across a field winding of the motor by means of a master controller. The contactors cut resistances out of the motor circuit and do not interrupt the field circuit when they operate. The field of the motor may comprise a principal section 2 carrying, say, nine-tenths of the motor current and an auxiliary section 4 carrying one-tenth of the motor current. By operation of the master controller 13 the contactor windings 11, 9, 7, 5 are connected in turn in series with the field section 4 and across the field section 2 and such part of the series resistance 3 as is in circuit. The operation of the contactors cuts out the resistance 3 in steps. The windings 11, 9, 7, 5 may be connected in parallel instead of series and the resistance 3 may be outside the energizing circuit for the contactors. Alternatively, the motor field may be divided into four equal sections and the contactor windings energized by insertion one in series with each of the field sections. In a further alternative arrangement the motor field is in a single section across which the contactor windings are successively connected. For remote control the drum controller 13 may be replaced by a contactor panel operated by a distant control drum, or, in the case of railway vehicles the contactors may each have an additional contact arm controlling contactors on another coach. Specifications 430,029 and 434,189 are referred to.
