Title: Improvements in or relating to metal casting machines
Inventor: DAVIS RALPH PERCY
IPC: B22C13/08
Filed: 1954-12-15
Abstract: 762,058. Casting-machines. WALWORTH CO. Dec. 15, 1954, No. 36332/54. Class 83 (1). [Also in Group XXX] A casting-machine comprises a number of casting-boxes 58 on the radial arms 22 of a rotary-carrier, and means 26, 32 for rotating the carrier to move the boxes sequentially under means 78 for loading granular refractory material into the space between the sides of the box and a complete shell-mould spaced therein. Two such carriers are provided, but the operations regarding one box 58 in one of the carriers will be described as exemplary. Shell mould halves are positioned in the box 58 and the carrier is indexed by the fluid-pressure device 32 having a rod 36 carrying a hook 38 to engage a peg 26 on the underside of the carrier. The hook 38 is first freed by a further device 42 which-swings the hook 38 away from the peg-26 and allows the rod 36 to be retracted. As the rod 36 advances, a cam-rod 52 moving therewith gradually closes a valve 48 to stop the carrier in the correct position. At the loading station, nozzles 106 are lowered towards the box by a manually-operated rack-and-pinion 114, 110 or by a fluid-pressure device 122. Fluid-pressure means 90 then open gates 84 and allow steel shot from the hopper 78 to flow around the shellmoulds until the shot reaches up to the nozzles 106 and shuts off the flow. The operator closes the gates 84 and retracts the nozzles 106 to allow the shot remaining therein to fall into the box. Rubber or like linings 72 on each side of the box are expanded outwardly by fluid pressure to compress the shot around the mould. The carrier is then indexed to a pouring-station where the moulds are filled. When the box reaches its last position, pressure behind the linings 72 is released. A pressure-device 66 is next actuated to swivel aside a bottom plate of the box 58 to allow the shot to fall into a chamber 140, the mould being retained on bars 70. The chamber 140 empties into a container 144 through a hinged shutter moved by a fluidpressure device 168 controlled by a solenoidoperated valve. With the shutter closed, pressure is admitted to the container 144 to convey the shot back to the main hopper 78 via a pipe 152 and a dust separator 154. Specification 762,063 is referred to.

Abstract: 344,352. Signs. UNITED SIGNS (1929), Ltd. and AYLES, S., 46, King William Street, London. Nov. 27, 1929, Nos. 36399 and 37390. [Class 3 (ii).] A sign facia comprises characters formed partly of transparent or translucent material for transmitting light from a rear source of artificial illumination, and partly of bright, ribbed material adapted to reflect light incident on the front of the sign. As shown, the facia comprises a front glass plate a which is rendered relatively opaque except for the character, which is left transparent or translucent and may be defined by a painted border f. Behind this is an opal diffusing sheet e, and between the two sheets is a cut-out stencil c of the ribbed reflecting material, the cut-out spaces b of which are narrower than the characters formed on the plate a so that the effect of a bright reflecting margin is obtained. Alternatively, the spaces b may be filled with the reflecting material, the margins being left translucent. In order to obtain colour effects which are different for transmitted and reflected light, the sheet e may be coloured throughout but provided on its front surface with an opal reflecting layer of a different colour; the same effect could be obtained by the use of a rear coloured coating on the plate e, or of a second plate located behind it. The plates a, c and e are preferably united at their edges to form a compact unit. Specifications 302,703 and 313,507, [both in Class 3 (ii), Advertising &c. other than by moving &c.], are referred to.

Title: Heat Shrinking Apparatus
Inventor: CARMICHAEL KEITH STEWART
IPC: B65B53/06
Filed: 1967-08-09
Abstract: 1,159,625. Shrink wrapping. E.I. DU PONT DE NEMOURS & CO. 9 Aug., 1967 [10 Aug., 1966], No. 36618/67. Heading B8C. [Also in Division F4] An apparatus for shrinking the protruding areas of a heat shrinkable film overwrap in the form of a sleeve comprises a tunnel that has at either end two discharge ports blowing hot air into the tunnel and directing the air on to the protruding areas. The whole overwrap may then be uniformly shrunk in a second tunnel. Air enters oven A by openings 32, passes through blower 68, over an electric resistor heater 34, via holes 36 into two pipes 20 and thence via ducts 22 to discharge ports 28, arranged in pairs at both ends of the tunnel. A probe 38 regulates the air temperature. Swivel elbow joints 26 permit the direction of the air stream to be varied. When no package is in the tunnel, ducts 22 are positioned so that the ports 28 blow air into openings 32 for recirculation. When a package enters the tunnel a sensing arrangement, e.g. a light 40 and photo-cell 42 arranged diagonally across the tunnel, actuate a cylinder 44 whose piston-rod 48 operates via rods 52, 54 to rotate pipes 20 about their axes and thus move ducts 22 into the operating position shown. After leaving oven A, the package may have its overwrap uniformly shrunk in a second oven (B) (Figs. 1 and 3, not shown), comprising a tunnel whose top, bottom and walls comprise an arrangement of diffuser plates (Fig. 9, not shown) through which heated air is passed and conveyer 14 may have a surface made up of idler rollers that in oven B may be caused to rotate by stationary friction members beneath them to cause the package to accelerate and thus assist uniform shrinkage.

Title: Ferrous-metal ingots
IPC: B22D7/10
Filed: 1971-08-04
Abstract: 1344180 Hot tops for ingot moulding casting processes J C DAUSSAN G DAUSSAN and A DAUSSAN 4 Aug 1971 [7 Oct 1970] 36657/71 Heading B3F [Also in Division C3] A hot-top liner sleeve for fitting in the mouth of an ingot mould or into a head box comprises a heat-insulating or an exothermic body having a metallic reinforcement at least partly embedded in the heat-insulating or exothermic material and a duct communicating the space bounded by the sleeve with the metallic reinforcement, such that, when in use, and when metal enters the space bounded by the sleeve, the metal enters the duct, and welds to the metallic reinforcement. The liner sleeve will adhere to the cast ingot, thereby allowing ingots to be stripped from their moulds before they are completely solidified, without the danger of molten metal spillage from their feeder heads. As exemplified, an ingot mould 1 (Fig. 1) has a liner sleeve comprising four flat tiles 12 and four copper wedges (not shown) each with a wire mesh reinforcement 14. Ducts 16 cross the reinforcement 14 and are vented at the rear or outer face of the liner by pipes 15. In alternative embodiments the ducts need not be vented and the corner wedges need not be provided with metallic reinforcements. As shown in Fig. 6 the liner can comprise four tiles 22 with chamfered edges and a reinforcement in the form of a box-pleated metallic members 29. Fig. 19 shows one of four tiles 52 each including a corner portion and a wedging surface 53, which may be  fitted into an ingot mould or head box. Each tile 52 has a bent reinforcement 55 and shallow sloping side ducts 56 communicating the reinforcement 55 and space interior of the assembled liner. The liner may be made a flexible assembly comprising two or more tiles 62 (see Fig. 23) hinged together by a reinforcement 65 at a narrowed portion between two tiles. An assembly of two pairs of tiles 62 may be held in a square sectioned mould or head box by two  clamping wedges (not shown) one at each of two opposed corners of the mould or head box. Liners consisting of one-piece annular mouldings may also be employed (not shown). Casting processes.-As shown in Fig. 27, tiles 82 may be bent over at their tops 83 to form a mould lid with a central aperture 89, into which a hopper 4 fits. Exothermic or insulating powder 5 is dispensed from the hopper on top of the cast ingot 2.
Patent GB-367084-A (GB)
Abstract: 367,084. Knitting-machines. SPIERS, Ltd., W., SPIERS, E., XL Works, Walnut Street, and HURD, J. C., Laneham, Kirkland Road, both in Leicester. Dec. 15, 1930, No. 37745. [Class 74 (ii).] For use with yarn changing plating or splicing mechanism a block 2 is furnished with as many vertically slidable trapping elements 3 and co-operating yarn receiving notches as there are yarn guides 1. Each trapper has a bust 9 operable, by the tip of the corresponding guide as it goes out of feeding position, to open the trapper. When, on reverse movement of the guide to an intermediate inoperative position, the trapper is released by spring means, the upper inclined edge 3a traps the yarn against a fixed shoulder. The pivoted guides are held inoperative against the action of springs 10 by cam pieces 11 on a pattern drum. The ribs 13 by acting on the guides cause the corresponding trapper to open and the yarn to be laid in the associated throat d. In a modification, the trapper is opened momentarily. Cutting edges on the trappers or independent yarn cutting means may be used. When the invention is applied to dial rib machines, one or more rib needles, provided with shorter butts than the rest, and caused to clear before reaching the feeders, engage the yarn extending from the trapper to the corresponding guide.

Title: Mechanical binding apparatus for hay, fodder or straw
IPC: A01D37/00
Filed: 1930-12-05
Abstract: 368,808. Binding-machines. LOISEAU, F., 33, Rue Violet, Paris. Dec. 5, 1930, No. 36719. Convention date, Dec. 17, 1929. [Class 6 (iii).] In a machine for binding hay fodder or straw, the hay &c. is fed into the hopper 1 either by hand or by an elevator 13 where it accumulates against a curved portion 2 of the hopper and is caught and lifted by compressers 3, the quantity of hay &c. taken by the latter being limited by separators 14 so that regular bundles are formed. The compressers 3 move the hay &c. up to the point 20, Fig. 2, where a second set of rakes 7 push it into the compression box 18. The ends of the bundle are thus turned in to form a U-shaped bundle, being assisted in this operation by lateral takes 15, 15<1> which pass through apertures in the parts 19. The weight of the bundle then acts on a pedal system of known type which operates a clutch, thus interrupting the movement of the compressers and operating a binding mechanism of known type.

Title: Improved ink conditioning means and method for lithographic printing devices
IPC: B41F31/00
Filed: 1954-12-22
Abstract: 755,417. Lithographic printing-machines. TUCKER, R. C., NEVAMPA, S. E., and CHILDERS, W., [trading as INTERSTATE OFFSET PRODUCTS CO.]. Dec. 22, 1954 [Jan. 5, 1954; Sept. 29, 1954], No. 37082/54. Class 100 (2). In a lithographic printing machine where water and ink are successively applied to a printing plate, the water content of the ink is controlled by subjecting part of the ink, e.g. on the surface of one of the inking rollers, to a current of heated air which evaporates part of the water. As shown in Fig. 1, the plate cylinder 110 is contacted by damping rollers 112 and inking rollers 114. Ink is fed to these latter rollers from a reservoir via a train of rollers 134, 132, 128, 124 and a central roller 120. From this roller the ink is transferred by rollers 118, 116 to the inking rollers 114. Moisture from the printing plate is picked up on rollers 114 and fed back towards the reservoir where it forms an emulsion with the ink and spoils its printing qualities. A drying apparatus 136 is arranged to direct a stream of hot air against the roller 120 so as to extract water from the ink returning to the reservoir as indicated by the arrows. Deterioration of the ink is thereby prevented. As shown in Fig. 8, the drying apparatus consists of a hollow casing 14 having a slot 18 in the bottom which extends the length of the inking roller 120 upon which the ink is to be dehydrated. Air is passed into the casing from a blower 23 (Fig. 1), the air passing through a channel 22 and apertures 21 in the top wall of the casing. The apertures surround an electric heater element 30 so that the air is heated as it passes into the casing. A trough-shaped baffle 35 under the heater extending the length of the casing causes the air to follow the paths shown by the arrows before being discharged against the surface of roller 120 through slot 18. The slot 18 may be closed over part of its length by sliders which can be inserted to block the flow of air to areas of the inking roller which do not require drying. The amount of air flowing can be varied by adjusting the damper plate on the inlet part of the blower. The casing is carried on brackets at the ends attached to pivoted arms with a screw adjustment so the proximity of the slot 18 from the surface of the inking roller can be adjusted. The outlet slot 18 may alternatively be arranged at the top of one side wall of the casing.

Abstract: 1,068,638. Boring earth etc; casings. JOHNSON CONSTRUCTION CO. A. B. Sept 11, 1964 [Sept. 11, 1963], No. 37294/64. Heading E1F. Drilling equipment comprises a percussive bit 13 carried by a drill rod 12, and a percussive bit 11 releasably coupled to and actuated by the rod. A coupling 24 which fixes the bit 11 to the rod has a bayonet connection with a coupling 20 fixed to the bit 11 which is rotatable on a pipe 10. The rod which has a protector 32 is rotated during drilling through soft overburden so that the bits have a percussive and rotary action, the bit 11 being followed by the pipe. When bedrock is reached drilling is stopped, rotation of the rod is reversed to withdraw the rod and bit 13, and a rod and bit having no connection with the bit 11 are inserted into the pipe and actuated to drill the bedrock. After the hole is completed the rod and its bit are withdrawn, a plastic tube is inserted into the pipe, and the pipe withdrawn leaving the tube.

Title: Snap action switch
IPC: H01H13/28
Filed: 1965-09-02
Abstract: 1,103,188. Switches held set and freed mechanically. BOYNE PRODUCTS Inc. 2 Sept., 1965 [14 Sept., 1964], No. 37529/65. Heading H1N. A generally planar rigid contact blade 20 is pivoted in the notches 18 of the arms 16 of a conductive mounting member 10 (see also Fig. 1, not shown), and moves with a snap-action between a contact 14 and a stop 24 when a generally cylindrical operating member 26 is moved through the plane of the blade up inclined guide surfaces 19, and a tension spring 31 interconnecting the blade 20 and the operating member 26 causes the pivotal movement of the blade 20. The actuating means 37 is a rotatable shaft 38 causing upward movement of a screw 40 so that its head 41 moves the operating member 26 to snap contact blade 20 away from contact 14. Continued movement of member 26 up the inclined guide surfaces 19 of mounting member 10 stresses the spring 31 to provide a restoring force on blade 20, but the blade 20 returns to contact 14 only when shaft 38 is rotated back to its initial position. Alternatively, successive actuations of a button (94) cause a wedge (84) on a reciprocating plunger (83) to actuate the operating member (74), (Figs. 3, 4, not shown), of a similar mechanism, with a change-over contact blade (71), the spring (77) and guide surfaces (65) tending to restore operating member (74). A mechanism similar to that of a conventional ball-point pen retains a rotatable cup-shaped member (88) in one position after a first actuation of button (94), until a second actuation re-aligns ribs (90) of casing (50) with grooves in the flange (89) of member (88) by rocking of member (88) via interacting teeth (91) and (92). The two casing parts are riveted together at (53), (54). In Fig. 2, the cover 9 is a snap-fit and the switch is mounted by wings (3), (Fig. 1, not shown).
