Title: Improvements in or relating to machines for expressing liquids from solids
IPC: B30B9/12
Filed: 1943-06-01
Abstract: 571,019. Presses for separating liquids from solids. BIBBY & SONS, Ltd., J., and KILLIP, R. E. June 1, 1943, No. 8729. [Class 46] In a press for separating liquids from solids, such as oil from nut kernels, comprising an extruding worm rotating in a cage provided with pores or openings for the exuding liquid and adapted to be opened up to give access to the interior, the opening movement is effected in a horizontal direction with the opening parts supported during such movement, for instance by the opening parts being hinged on a vertical axis. As shown in sectional part elevation, Fig. 1, and sectional plan, Fig. 7, a main frame 10 provides bearings 13 for a vertical shaft 16 on which worm flights 17 are fixed to rotate within a cage formed by longitudinally arranged bars 25, which provide openings between themselves for the exudation of expressed liquid and which are assembled in half-ring members 26 hinged on a vertical rod 28 so as to be capable of being swung open in the horizontal direction, to give access to the interior of the cage. The cage is held in the closed position by a U-section clamping bar 31, which is tightened on to co-operating wedge-shaped members on the half-ring members by two hand-wheels 36 and screws 33, the latter having a collar 34 to engage a recess formed in the wedge-shaped members so as to prevent axial movement of the screws. The two hand-wheels are connected by a chain 38 and sprockets 37-for operation together, but one can be declutched by means of a pin 39 so as to allow. independent operation for final tightening. The weight of the clamping bar is taken up by a runner rail 41. The separated liquid passes to a trough 42 having a screen over which pass scrapers 44 to remove any fine solids which may have passed through the exudation openings of the cage. The scrapers are carried by a wheeled member running on the edge of the trough. The bars of the cage are divided at points 27 into a number of axial sections so that after wear a section can be transferred to a preceding axial position, the first section being scrapped and only the last section needing a new' replacement. The extrusion area 49 is varied by means of cone member 49a adjustable through a hand-wheel 49c and gearing 49b. Material is fed from the hopper 23 by a feed worm 24, driven through a ratchet gear 56 from a spring-loaded telescopic connecting rod 57 so that the feed is automatically adjusted in accordance with the pressure. The cake of solid from the extrusion nozzle is swept out from the lower chamber by a rotating arm on the vertical shaft 16. The lubricating oil for the driving gear is kept cool by a fan blowing air on the gear enclosure. The opening movement of the halfring members of the cage may be effected by outward horizontal movement on supporting rails, Figs. 9 and 10 (not shown). Specification 571,046 is referred to.

Class 142(2) A device for cutting the weft of an exhausted bobbin near the shuttle and clamping the end attached to the selvedge comprises cutting and clamping jaws mounted in a head 88 slidable in a fixed body 50. When the transfer hammer dog is lifted into the path of the striker on the slay, an arm 65 on the same pivot 35 as the dog turns clockwise and through linkage and levers 58, 56, 75, 81, 84, projects the head 88 to the left (towards the slay) as shown. During this movement, the cutter jaw 91 and the clamping jaw (not shown) are opened by their tails 95 riding on a ramp 98 fixed in space by being attached at 100 to the body 50. As the slay beats up, the weft thread enters the jaws and a striker on the slay pushes the head 88 to the right by engaging an abutment 104; surfaces 96 on the clamping and cutting blades ride on to the ramp 98 in succession, whereby the weft is clamped, then cut. The slay also actuates the transfer hammer dog carried by the pivot 35, thereby moving the pivot and the arm 65 bodily to the right, causing the arm 56 to turn clockwise, whereas movement of the head 88 to the right has caused the arm 75 to turn anti-clockwise; the opposite movements of the arms 56 and 75 are catered for by a clutch 64 consisting of spring-loaded pins 73 in one half which ride out of grooves 72 in the other half under these circumstances. As the slay recedes, the pivot 35 returns to the left, turning the arm 56 anti-clockwise to its original position, in which the clutch 64 re-engages.

Title: Improvements relating to component attaching machines
IPC: B23Q7/14
Filed: 1957-03-20
Abstract: 821,887. Assembling components on printed circuits. ADMIRAL CORPORATION. March 20, 1957 [March 26, 1956], No. 9128/57. Class 83 (2). Mechanism for moving a component receiving part such as a printed circuit board B to at least one working station P, Q, R, comprises a guide-rail 46 movable in opposite directions and having a lateral groove 49, Figs. 7, 11, extending in a different direction and within which one edge of a board B, discharged from a magazine M, is slidable to said station, whereupon the guide-rail carrying the part is moved in one of said opposite directions for moving locater portions 54, Fig. 7, in one edge of the board B into engagement with fixed locater pins 52, Fig. 11, at said station. The magazine M houses a stack of horizontal boards B and comprises relatively adjustable side-rails 27, 28, Fig. 7, and relatively adjustable end rails 29, 31, each rail having a pair of upstanding rods 32. The lowest board of the stack is discharged through a gate 39 beneath the forward rail 31 by a reciprocating rod 42 driven by a fluid-pressure motor 45, Fig. 1, and enters a horizontal side groove 49, Fig. 7, in a vertically-movable guide-rail 46 which is then in its upper position. When the board reaches the first working station P, the rail 46 is lowered by horizontally movable cams 68 whose inclined cam slots 80 engage followers connected to the rail 46; the cams are mounted on a bar 57 moved by a fluid-pressure motor 58. Location holes 54 in the board thus pass over the fixed locater pins 52, Fig. 11, at the station for accurate positioning of the board when the latter is lowered on to anvils 19. Spring restrainers 56, Fig. 7, restrain the movement of the board along the groove 49. After the working operation the board is raised and transferred along the guide-rail 46 to the next station by a latch member 86, Fig. 20, mounted on a bar 44 reciprocated by the motor 45 and having a depending peg 103 engaging in a hole 104 in the board B. The latch member may be released manually from engagement with the board B by raising a lever 106, Fig. 15 (not shown), which is normally retained in a horizontal position by a spring-loaded catch. Shoots 131, Fig. 20, are used for discharging the trimmed ends of components fixed to the boards B. Deflector ramps 134 ensure that any upstanding leading edges of the boards pass beneath the shoots.

Abstract: 676,263. Gas-producers; oil gas generation. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 16, 1950 [Jan. 14, 1949], No. 9270/50. Divided out of 676,208, [Group XXVI]. Classes 55 (i) and 55 (ii). In a gas producer for gasifying solid or liquid carbonaceous material of the kind having a combustion chamber which is circular in section and has a peripheral inlet through which air passes to set up a radial inward vortex flow in the chamber, the material to be gasefied being injected into the vortex for its partial combustion whilst the combustible gases generated discharge through an axial outlet, at least one of the end walls of the chamber is provided with a jacket through which the air flows from an axial inlet radially outwards to a peripheral outlet which communicates with the peripheral inlet of the combustion chamber, the end wall being thus cooled by the air whilst the air is preheated. An example of the treatment of fuel for its complete combustion in apparatus of the above kind is described in Specification 338,108, [Class 55 (ii)]. In the form shown, the apparatus consists of a double-walled, circular section, combustion chamber 3 having an axially-mounted oil or finely-divided coal &c. injector nozzle 11 at one end and an axial gas outlet at the other. Air under pressure is supplied simultaneously to volutes 14 and 15 surrounding the injector and gas outlet respectively, and flows in a spirally outward path in the space between the double walls 2 and is thus preheated. The hot air enters the chamber 3 through inclined vanes mounted around its periphery, the vanes increasing the spinning motion of the air and gases in the chamber. The fuel particles injected by the nozzle 11, which is preferably of the rotary type described in Specification 639,483, so as to enable the particle size to be controlled, are carried around by the air, the larger particles being burnt in an outer zone and the smaller particles moving around in an inner zone where they are gasefied by the heat of combustion of the larger particles. The generated combustible gas discharges through the axial outlet pipe. In a modification, Fig. 3 (not shown), this gas then passes to a second vortex flow chamber where cracking of condensible vapours to produce fixed gases occurs. In both modifications the combustion chamber walls may be additionally cooled by a waterjacket, steam generated from the jacket being injected into the chamber to take part in the gas generating reactions.

Filed: 1920-03-31
Abstract: 164,559. British Thomson - Houston Co., Ltd., (General Electric Co.). March 31, 1920. Induction relays; actuating.-Relays having rotary armatures such as induction discs, are constructed to operate completely at a given current by moving throughout their entire range into the circuit-closing position, notwithstanding the increasing control torque afforded by a spiral spring, by augmenting the motor torque at the beginning of the movement, the induction disc driving the contact-member through an electromagnetic coupling which is released as soon as the circuit is closed, or if the current falls off during the closing movement permitting the immediate rapid return of the contact-member independently of the disc. In the arrangement shown, the disc spindle 8 carries one disc 9 of an electromagnetic clutch normally spring-pressed against a similar disc carried by a sleeve 5 loose on the spindle and under the control of the spring 4. The sleeve carries the movable contact 6 normally engaging an adjustable stop 26 to vary the range of movement. When current flows through the coil 15 of the relay, it exerts a torque on the disc 1 and inductively energizes the auxiliary winding 18 which is connected with the winding of an electromagnet operating the plunger 22. With adequate current in the winding 15, the plunger is raised, causing a displacement of the phase of the current in the winding 18 and a resulting increase of the motor torque sufficient to move the contact member over to the closed position energizing a local circuit containing the tripping coil of the main switch and a coil 14 the pole-piece 12 of which separates the magnetic coupling-discs so that the sleeve and the contact-member return to the ' off ' position under the action of the spring 4 at once and independently of the induction disc. When the plunger 22 is raised and the disc begins to move to the closed position, a contact arm 30 on a swivelling magnet embracing the disc is released by a double-armed lever 34, 36, 35 and the contacts 31, 32 would come into engagement under the action of the spring 33 except for the drag on the magnet produced by the steady movement of the disc during the closing movement. If, however, this movement is retarded owing to a reduction in the driving current, the contacts 31, 32 engage one another, thereby connecting a coil 13 across the winding 18 and separating the coupling discs to cause an immediate return of the contact member to its initial position independently of the induction disc.
