Title: Improvements in conveyors for pulverulent materials
IPC: B05C19/06
Filed: 1948-02-13
Abstract: 633,276. Pneumatic conveyers. BASIC REFRACTORIES, Inc. Feb. 13, 1948, No. 4266. Convention date, April 15, 1947. [Class 78 (i)] In a conveyer for granular or pulverulent materials, the material is forced by compressed air from a hopper into a zone surrounding an air jet and projected thereby in a confined stream, liquid being injected into the stream before its release. Material is admitted to the hopper 2, Fig. 1, through an inlet 3 provided with a closure 6 and is discharged therefrom by compressed air through an outlet controlled by a ball valve 4 to a chamber 5, Fig. 5, in which is a nozzle 35 for compressed air. The material is forced from the chamber 5 through an outlet 36 and pipe 37 to a discharge nozzle 38. Liquid is passed into the stream from supply pipe 47 through radial inlets 46, Fig. 6. The valve rod 29, Fig. 5, is guided by a bushing 32 at the top of the hopper and is connected through a lostmotion device 30, 31 to an arm 28 fast on a shaft 27 which is turnable by a lever 26. The closure 6, Fig. 2, is pivoted loosely to an arm 8, Fig. 2, which is pivoted at 7 to the hopper. An extension 12 of the arm 8 is connected by links 13, 18, Fig. 3, to an arm 17 on a stub shaft 15 carrying a hand wheel H. A spring 23 is confined between a nut 22 on the end of the link 13 and a cap 24 which closes the end of the cylindrical part 20 of the link 18. A stop 9 limits the movement of the closure 6 with respect to the arm 8. By these means the closure 6 is opened inwardly to a position which is entirely out of the path of material passing through the inlet 3.

Title: Improvements in machines for spinning hollow-ware from sheet-metal blanks
IPC: B21D22/16
Filed: 1924-02-19
Abstract: 235,610. Herden, W. Feb. 19, 1924. Addition to 211,864. Spinning.-The machine described in the parent Specification is provided with a vertical joint m between the slotted bar k and the roller so that this can swivel automatically or by hand when the former c has a reflex curve. The roller p is pressed towards the former c by a bell crank pivoted at s. A weight q is moved along the arm a of the bell crank by a lever W having an adjustable pivot z, a link x which is pivoted at a point y having adjustable eccentricity relative to the pin h. Thus the pressure of the weight increases as the roller p travels from the centre of the former c but it is relatively decreased if the roller carrier n is turned about the joint m in a direction reverse to that in which bar k has been turned about the pin h. The speed at which the weight A, for moving the roller, falls is limited by a ratchet wheel F secured to one wheel C and geared to another wheel D over which the cord T passes. The ratchet wheel is engaged by a pawl J on a worm wheel H driven at a slow speed as shown. In a modification the weight q, Fig. 3, is arranged to compress fluid in a cylinder 1 which connected by a pipe 3 to a cylinder 2 in which moves a plunger 6 carrying the roller p which can be withdrawn by a handoperated self-locking device 8. The effect of the weight is modified by a weight 9 which is connected to it by a rod 10 resting on a fixed roller 11 and hence acts in the reverse direction and produces similar results to the first modification. The link x, Fig. 3, is adjustable in length.

Filed: 1974-02-01
Abstract: 1458855 Valves; pipe couplings ROBERT BOSCH GmbH 1 Feb 1974 [3 Feb 1973] 04675/74 Headings F2V and F2G  In a device for inflating tyres from the compressed air supply of a vehicle braking system, the pressure regulator of the system incorporates a changeover valve, operated when an inflation tube is attached to a connector, and a safety valve. In the normal position of a valve closure member 7 compressed air from a compressor 3 passes through the regulator to a chamber 8 and thence to an outlet for connection to an air reserovir 4 which feeds the brakes via a control valve 5. When an inflation tube is attached to the connector 14 a hollow control member 9 presses a planar surface of the closure member against a seat 11 to cut off the air supply to the reservoir 4 and at the same time its spherical surface leaves a seat 10 to open up a supply of compressed air to the connector for inflating the tyre.  Should the pressure at the chamber 8 exceed a predetermined value while a tyre is being inflated a safety valve closure member 15 lifts from its seat 16, against a loading spring 14, and air is vented to atmosphere via apertures 20. The closure member 15 is made of an elastic material backed by a metallic disc 19. The closure member moves on the hollow control member 9 and is sealed thereto by a sealing lip 18.

Title: Improvements in or relating to cross-bar switches of the type used in telephone systems
IPC: H01H67/26
Filed: 1952-02-22
Abstract: 722,435. Electric selectors. STANDARD TELEPHONES & CABLES, Ltd. Fell. 22, 1952 [April 13, 1951], No. 4730/52. Class 40 (4). An electric selector comprises a set of fixed parallel conductors carrying resilient contact extensions movable into engagement with corresponding members of another set of fixed parallel conductors perpendicular to the first set, movement of the contact extensions being effected by one of a set of fingers movable perpendicularly to both sets of conductors. The invention is applied to flat switches such as are described in Specification 662,784 and 722,438, which can be stacked to operate as a cross-bar switch. A set of parallel strip conductors 5 fixed to an insulating plate 2 carry resilient contact extensions 7 for cooperation with one or other sets of perpendicular conductors 4 and 41 fixed by passing through holes in the insulating plate. Each extension 7 engages in a narrow slot 12 in an associated finger 10, which also has wider slots 12<1> to permit free relative movement of the extension 7 associated with the adjacent finger. The fingers 10 are biased to a central position by levers 41, 41<1> spring-pressed against stops 42, 42<1>. Depression of one or a vertical set of clutch levers 24, as by a select bar in a cross-bar switch, engages the vertical set of levers 24 in corresponding notches in hold bars 20, Figs. 1 and 5. Movement of one of the bars 20 in one or other direction rocks the selected clutch lever 24 and its associated second clutch lever 26 to move the associated finger 10 longitudinally to engage the selected extensions 7 with one or other set of conductors 4 or 4<1>. The select bar can return to normal position, the connection being maintained until the hold bar is restored. The switch may be duplicated below the insulating plate 2. Control of hold bar 20. Operation of magnet 52, Fig. 6, rocks lever 54 counter-clockwise to cause nose 64 of lever 61 to depress a pair of levers 48, 49 whereby their ends 50, 51 engage over a bar 74. The bar 74 can be moved in either direction by apparatus not shown to push lever 48 or pull lever 49 so as to move the bar 20 longitudinally in one or other direction. The projection 66 or 67 on the lever 48 or 49 slips over the end of the nose 64 under the action of spring 75 or 76 to hold the bar 20 in displaced position until the magnet 52 restores.

Abstract: 1,169,087. Feeding sheets. MABEG MASCHINENBAU G.m.b.H. NACHF. HENSE & PLEINES G.m.b.H. & CO. 1 Feb., 1967, No. 4802/67. Heading B8R. Pile tables.-The lifting and lowering of the sheet stack 5 of a sheet processing machine is controlled by a multiple position limit switch 13 settable in a position 15 connecting the drive means for lifting the stack carrier 3 and in a position 14 for lowering the carrier, the switch having a third intermediate position constituting an " off " position. A detecting means comprising arm 11a supporting roller 11 engages the top surface of the stack when this reaches a predetermined upper level snapping arm 12 from the " up " position to the " off " position. The descent of the stack is arrested at a predetermined lower level position by chain 2, which forms part of the drive transmission to carrier 3, forcing arm 12 out of its " down " position via arm 19 and into the " off" position. Arm 20 is engaged by set screw 8 to move switch 13 from the " up " to the " off " positions when the carrier 3 is being raised without a stack thereon. Progressive raising of the stack as sheets are removed by separator 32 is controlled by switch 35. Probe 24 follows the descent of the top surface of the stack and at a predetermined level closes switch 35, which, provided switch 12 is in the " off position, energizes auxiliary lifting motor 30 to raise the stack until contacts 26 and 27 of switch 35 once again become disengaged.

Title: A resilient assembly for a vibratory system
IPC: F16F9/04
Filed: 1961-02-10
Abstract: 913,949. Pneumatic springs. CHAIN BELT CO. Feb. 10, 1961 [Feb. 15, 1960], No. 5087/61. Class 108(3). Air springs 19, which have lateral stability and provide strength against lateral deflection of an excitor 16 mounted in a frame 14 of a vibratable conveyer 10, each incorporate a stabilizer 21 comprising an annulus 33 of elastomeric material which is bonded to a central pin 31 threadedly engageable with an upper end plate 22 and is radially compressed to fit, without slippage, within, a cylinder 30 secured to a lower end plate 22. The. plates 22, having threaded sockets 26 for receiving bolts for securement to the support frame 14, have rolled edges 23 which grip marginal beads 24 of a flexible, but not stretchable, side wall 25 which is preferably made of a fabric reinforced elastomer. The elastomeric annulus shown in its free form, Fig. 3, is compressed to reduce its radial thickness by approximately 12% the marginal axial thickness at thesame time being increased by 30%. The radial compression of the annular resilient member provides a force which tends to urge the pin 31 axially away from its neutral position with a force which varies with the degree of axial displacement and opposes the shear resistance of the material. In a modification, Fig. V, where it is undesirable to have uniform lateral stability in all directions, the stabilizer comprises a tongue 46 welded to an upper end plate 40 and sandwiched between a pair of rubber blocks 47, 48 which are compressed between the limbs of a U-shaped bracket 49 which, during assembly, is screwed into the lower plate member 42. An inlet connection to receive an air supply line 20, Fig. 1, is included in one of the plates 40.
Patent GB-627630-A (GB)
Title: Polyphase frequency modulators
IPC: H03C3/24
Filed: 1947-02-21
Abstract: 627,630. Frequency modulation. STAN. DARD TELEPHONES & CABLES, Ltd. Feb. 21, 1947, No. 5134. Convention date, Sept. 1 1945. [Class 40 (v)] A polyphase frequency modulator comprises a number of oscillation generators in which the anode of each oscillator valve is coupled by a phase-shifting network to the control grid circuit of the next valve to maintain a constant difference between the phases, each network comprises a first impedance coupling the anode to control grid and a variable resistor between the control grid and ground, this resistor comprising the anode to cathode impedance of a control valve, the frequency of oscillation of the system is varied by applying a modulating signal to vary the grid bias of the control valves. In the Figure, valves 1, 2 and 3 represent three valves oscillating at the same frequency with a phase difference between them maintained constant by the interstage phase-shift networks. The impedance of the valves 36, 44 and 52 is altered by changing the control voltage Em applied to their grids, thus varying the effective resistance of the inter-stage phase-shift couplings and causing the oscillators to oscillate at a new frequency in order to maintain constant the phasedifference between them. In a modification, Fig. 2 (not shown), the oscillator valves are pentodes and a diode is connected between the screen grid of each valve and the cathode of the next to maintain the oscillatory output at constant amplitude. Each control valve has associated with it an additional valve, the impedance of which may be varied by varying the grid voltage of a third valve to which the grid circuits of the additional valves are all connected. Thus in a multi-phase frequency modulation system, the mean frequency of oscillation may be controlled by the grid voltage applied to this third valve and the frequency sweep may be brought about by an A.C. signal applied to the main control valves. Specification 580,467 is referred to.
