Title: Tire curing press
IPC: B29D30/06
Filed: 1965-07-13
Abstract: 1,102,904. Moulding tyres. NRM CORPORATION. 13 July, 1965 [28 Sept., 1964], No. 29691/65. Heading B5A. A tyre press for curing radial cord tyres, in which a tyre band is placed over an inflated bladder and held between upper and lower moulds 1 and 2 respectively, includes radially movable tread sectors 101 which, when the moulds 1 and 2 are brought into moulding position, are urged radially inwardly by a cam and lever mechanism to abut steps 41 and 21 of the moulds. The upper mould is attached to a platen 3 carried by a bolster 115 attached to the upper vertically and laterally movable part 123 of the press. Relative vertical movement between the bolster and platen is provided by a number of air springs 137 on rods 142 which urge the bolster upwardly to abut the heads 134 of screws 130. An annular housing 46 depending from the platen has circumferentially spaced openings therearound in each of which a block 86 attached to a tread sector is radially slidable. A lever 70 is pivoted at 80 to each block and at 68 to the housing 46, and carries a pin 77. When the moulds 1, 2 are brought into their operative position with the lower surfaces 107 of the sectors 101 in engagement with the surface 22 of the lower mould, further downward movement of the part 123 forces the bolster downwardly relative the platen 3. Cam members 148 circumferentially spaced around the bolster are thereby caused to engage the pins 77 which pivot the levers and force the tread sectors radially inwards. An annular plate 153 around the bolster carries pairs of lugs 156, one pair for each sector, which engage behind the sector blocks 86 to lock them in their radially innermost positions. After the moulding process and when the part 123 is raised, the lugs 156 engage the pins 77 to pivot the levers in the opposite direction and move the tread sectors radially outwardly. In the moulding position the tyre beads engage upper and lower rings 25 and 12, the upper ring forming part of a vertically adjustable assembly including a bladder ram 32 which, after moulding, moves down to force the bladder 18 into a well 16; simultaneously, plates 29 are moved radially outwardly by a pivoted link mechanism to below the upper bead of the tyre. This ensures that the tyre is carried upwardly with the upper mould after treatment. A tube 28 of the assembly is then moved downwardly and the ring 25 is lowered from the upper mould, causing the tyre to be stripped therefrom. The plates 29 are then retracted and the tyre drops away from the press.

Folding inner tabs. Annular sheets 10, 10a, e.g. of multi-ply cardboard, having a central opening 11 are supplied above and below a  roll of tubing at a position whence a hub 20 may be raised by means of a cylinder 32 and piston to hold the parts in place. The head 59  is lowered, enabling rollers 75, Fig. 3, carried by the fingers 71 to engage a presser plate 67, thereby urging the fingers outwards to fold the upper tabs 13. The lower head 48 is then raised, causing the head 59 to withdraw, and, by means of the fingers 29, folding the lower tabs 13 upwards. The head 48 and hub 28 are  withdrawn enabling the removal of the par-  tially completed carton. The movement of the  folding members is effected pneumatically,  trip switches operated by the moving parts causing the members to act automatically.  Folding outer tabs. The partially formed  carton is supplied on rollers 87, Fig. 8, to a  further tab-folding station, the rollers 87 being carried on beams 85, 86 which are adjustable on bars 82, 83 to fit different sized cartons. A rotary table 90 is raised pneumatically to lift each carton off the rollers 87. With the table raised, a plate 111 is moved inwards so that freely rotatable rollers 113-115 carried on the plate 111 may complete the folding of the outer tabs 17. The table 90 is rotated anticlockwise by an electric motor through an intermediate gear train. Each of the rollers 113-115 carries out a different phase of the folding process, Figs. 11-13 (not shown). The plate 111 is then withdrawn. A roller 122, carried on a supporting plate movable in the same way as plate 111, applies an adhesive tape 20 which is cut by a cam-operated knife 126. The table 90 is automatically stopped, after it has rotated through a fixed angle, and lowered, thereby depositing the completed package on the rollers 87 for removal. U.S.A. Specification 3,018,883 is referred to.

Abstract: 1,079,560. Casting processes. ALLEGHENY LUDLUM STEEL CORPORATION. July 13, 1965 [July 15, 1964], No. 29746/65. Heading B3F. [Also in Division F4] In a method of casting stainless steel in which the molten metal is tapped from a furnace 10 into a ladle 16 and then teemed into one or more ingot moulds 28, oxidation of the melt during tapping and teeming is prevented by purging the ladle and moulds with an inert gas such as argon prior to topping and teeming respectively and supplying a protective screen of the gas during the actual pouring from the furnace into the ladle and from the ladle into the mould. The inert gas displaces the air through openings 20 and 32 in the ladle and mould respectively. The gas is then supplied through port 38 in the furnace outlet and by means of a ring 46 positioned over the inlet to the mould. The gas being supplied through a regulator in each case. The opening in the ladle and mould are sealed with a frangible cover 22 and 34 respectively which is destroyed as the molten steel is poured. Other gases which may be used are helium, neon, krypton or xenon.

Title: Sewing machine, particularly blindstitch sewing machine
IPC: D05B85/06
Filed: 1955-10-19
Abstract: 783,384. Sewing machines. SINGER MANUFACTURING CO. Oct 19, 1955 [Oct. 22, 1954], No. 29824/55. Class 112 In a blindstitch sewing machine the work-supporting arm 18, which is carried by pivots 33, 34 journalled in the ends of a spindle 26 fixed in the machine frame, is provided with an abutment screw 47 which is biased against a block 38, journalled on spindle 26, by means of a stressed leaf spring 44 which is secured at one end by a screw 45 to block 38 and abuts at its other end against a screw 46 carried by arm 18, the arrangement being such that block 38 may either be locked to the machine frame, when spring 44 holds arm 18 in the operative position, or block 38 may be unlocked from the machine frame, when arm 18 may be lowered against the bias of a comparatively weak spring 42. A block 39, also journalled on spindle 26, is adapted to be fixed in adjusted angular position relative to the machine frame, for which purpose an arm 48 projecting from block 49 has a pin-and-slot connection with a rod 51 slidably mounted on the machine frame and adapted to be moved axially by means of a rotatable knob 54. A recess 56 in block 39 loosely receives a lug 57 projecting from block 38 for limiting angular movement of the latter. A pin 58 slidably mounted in block 39 is biased by a spring 61 into a slot 60 in block 38 to prevent angular movement of the latter. Pin 58 is connected to a bar 79 slidably mounted on the machine frame, whereby movement imparted to bar 79 serves to withdraw pin 58 from block 38. A rod 66, journalled in a bracket 63 on the machine frame, is adapted to be rotated by means of a knee press and carries an arm 73 having a wear-resistant tip 74 which normally bears against the vertical end 89 of bar 79. Initial anti-clockwise movement of rod 66 thereby serves to move bar 79 inwardly to free block 38, tip 74 then moving over an arcuate surface 90 on bar 79 centred on the axis of rod 66. The latter also carries an arm 68 connected by links 69, 70 to arm 18, the links having a lost-motion connection, whereby no force is transmitted to arm 18 while bar 79 is being moved by tip 74, and arm 18 is moved downwardly while tip 74 is moving over surface 90, arm 18 then being free from the biss of spring 44. In a modification leaf spring 44 is replaced by a coiled compression spring.

Patent GB-692030-A (GB)
Title: Improvements relating to moulding mixtures
Inventor: WIGLEY DONALD HUGH
IPC: B22C1/18
Filed: 1949-11-25
Abstract: A refractory mould is prepared by pouring around a pattern of an article to be cast a moulding mixture comprising a slurry formed by mixing a dry aggregate with an aqueous solution of sodium silicate to which an aqueous solution of sodium acid phosphate has been added immediately prior to the mixing whereby a silicic acid gel is precipitated and binds the aggregate together, then baking to decompose the gel and form silica which is the final binder. Concentrated hydrochloric acid may be present in the silicate solution.  In the example, a wax pattern is first cast, then sprayed with zircon flour suspended in a mixture of methylated spirit, ethyl silicate and hydrochloric acid.  When dry the pattern is dipped into a suspension of silica flour, silica sand and magnesia in ethyl silicate, methylated spirit and water, and then "stuccoed" with firebricks.  Such coated pattern is set up in a mould box, and the slurry of the mould mixture poured therein and vibrated.  When set the mould is stripped and dried.  The preferred aggregate is a mixture of magnesia silica flour and sand and crushed firebrick.

Title: Improvements in doffing apparatus in textile spinning preparatory machines
Inventor: WARRINGTON CLIFFORD
IPC: B65H67/048
Filed: 1959-09-04
Abstract: 886,076. Winding yarns; stop-motions. TWEEDALES & SMALLEY Ltd. Sept. 2, 1960 [Sept. 4, 1959], No. 30313/59. Classes 120(1) and 120(2) A doffing apparatus, Fig. 5, for textile machinery, comprises a bobbin supporting cradle 20 that is rotatable about a supporting shaft 19, means biasing the cradle 20 about the shaft 19 to press the bobbin 15 and its winding 17 against a driving roller 23, means for automatically locking the cradle 20 to the shaft 19 when the bobbin 15 is full, and means for automatically causing the shaft 19 and the cradle 20 to rotate to a position B where the wound bobbin is released. The cradle 20 is urged towards the driving roller 23 by a torsion spring reacting against the initially stationary shaft 19. A sliver 11, fed through a guide 13, is wound on to the bobbin 15 to form a cross-wound package 17 and as this increases in diameter the cradle 20 is forced away from the roller 23. When the diameter of the winding 17 reaches a predetermined value, a spring biased bolt in the cradle 20 enters a recess in the shaft 19 or a collar secured thereto to lock the cradle 20 to the shaft 19. A counter of known kind ensures that at this time the motor driving the roller 23 is stopped and that after a slight time delay a second motor coupled to the shaft 19 is started. The shaft 19 then rotates to move the cradle through stations A and B and, at the latter, the wound package engages a deflecting plate 40 that causes the package to leave the cradle 20. The shaft 19 performs a complete rotation to bring the cradle back to its starting position, at which instant a cam actuated micro-switch stops the motor turning the shaft 19. A machine operator withdraws the spring biased bolt manually and inserts an empty bobbin in the cradle 20. The wound packages roll into a tray 47 where they engage a switch arm 48 to open the circuit to the main driving motor. A fresh winding operation cannot, therefore, be started until the wound package has been removed. Each bobbin 15 may contain two wound packages in side-by-side relationship. Specification 878,671 is referred to.

Title: Method of improving the properties of regenerated cellulose fibres spun from viscose or cuprammonium solutions of cellulose
IPC: D01F2/08
Filed: 1951-12-28
Abstract: In the production of regenerated cellulose filaments from viscose or cuprammonium solutions of cellulose, there are incorporated in the spinning solutions sulphonic acid esters of alkanolamines of the formula (R1.SO2.OR)m.NHp.(ROH)n, where m and n are 1 or 2, p is 0 or 1, R is an alkyl radical and R1 is an alkaryl radical.  Preferably compounds of the formula (R1.SO2.OR)2.NROH are used.  Trialkanolamine esters or ethers of higher fatty acids or higher fatty alcohols, particularly those with cation-active properties, may also be added to the spinning solutions as animalizing agents.  Pigments, or dyestuffs containing residues having cation activity may also be added to the solutions.  In an example, 5 kgs. of copper phthalocyanide are mixed with 2.5 kgs. of triethanolamine-di-benzylethylene sulphonic acid ester of formula (CH2 : CH.CH2.C6H4. SO2.O.C2H4)2.N.C2H4.OH and added to 1,000 kgs. of viscose.  In the other example 2.5 kgs. of tributanolaminedi - ethylnaphthalene sulphonic acid ester having the formula (C2H5. C10H6.SO2.O.C4H8)2.N. C4H8.OH are stirred to form a fine emulsion with 25 kgs. of dilute acetic acid in which 5 kgs. of the triethanolamine diether of lauryl alcohol have been dissolved.  This emulsion is added to 1,000 kgs. of viscose.  The addition of the sulphonic acid esters to spinning solutions prevents the flocculation of other additives of strong cation activity, minimizes the clogging of spinnerets, particularly when delustring pigments such as titanium dioxide are added to the spinning solutions, increases the extensibility of the filaments spun from the solutions and improves their handle and absorptive capacity for acid dyestuffs.
