Title: Improvements in or relating to dispensers
IPC: A45D34/04
Filed: 1946-10-03
Abstract: 635,692. Paste &c. applicators. NEEGAARD, L. E. DE. Oct. 3, 1946, No. 29491. Convention date, Sept. 17, 1945. [Class 81(ii)] In a device for applying lipstick paste, by means of a spherical or cylindrical applicator, means are provided for clamping the applicator member when not in use and also for maintaining a constant pressure of the paste on the member. In one form the paste is contained in a body 1, Fig. 2, in which it is maintained under pressure by a spring-loaded plunger at the remote end of the body. The pressure causes the paste to adhere to a freely rotatable ball 5 and be conveyed to the exposed surface as this is passed over the lips. The ball is retained by three small projections 12 equally spaced around its circumference, the intervening spaces allowing free passsage of the paste. When the device is not in use, the cap 10 is screwed back slightly to clamp the ball against the bearing block 8. In other forms the ball is held in position by a permanent magnet. Thus, as shown in Fig. 7, the ball 51 is held against its seating by a magnet 45 and the paste reaches the ball through ducts 54, 52. This Figure shows a torsion spring for automatically returning the end cap 40 to its closed position when it is not in use. The Specification also describes the use of a cylindrical roller as the applicator in conjunction with a horse-shoe magnet, see Figs. 11 to 15 (not shown).

Title: Improvements in or relating to cigarette feeding devices for cigarette packing machines
IPC: A24C5/356
Filed: 1961-08-16
Abstract: 930,927. Endless conveyers; reciprocating conveyers. A. SCHMERMUND. Aug. 16, 1961 [May 2, 1961], No. 29515/61. Class 78 (1). Cigarette magazines 11 are fed by conveyers 64, 66 to a two-part frame 1, 2 which is rotatable from a position 11a (shown in dot-dash lines in Fig. 1) in line with the conveyer 66, to a vertical and inverted position 11b (in full lines). The part 1 of the frame is displaced from a position I (Fig. 2) to a position II where a slide 5, carried by the part 1 and closing the open mouth of the magazine 11, is displaced so as to release the cigarettes into a hopper 96, 97 of a cigarette packing machine 95. The empty magazine is then displaced to a storage position III to await removal. When the two-part frame 1, 2 is in position 11a, cranks 98 (driven by linkage from a cam on a shaft 32) engage a tail 4 of the slide 5 to move the latter into its magazine-closing position. The two-part frame 1, 2, is rotated from 11a to 11b by a rack 56 driven by a crank disc 61 and acting on a gear 57. The part 1 of the frame 1, 2 is slidable on a rod 3 (itself rigid with the part 2 and with the gear 57) from position I to position II by the action of a slide 19 driven by a belt 14 on a guide-rod 18. The slide 19 is connected to the belt 14 by a link 17. The axis of the link 17 is arranged to pass through the centre of one or other of the pulleys 12, 15, of the belt 14, at the dead centre positions of the slide 19. On arrival at position II, a crank-pin 105 (Fig. 6) carried by a shaft 109 mounted in parts 6 of the frame part 1, engages a link which is then actuated by a solenoid (M, Fig. 4, not shown) to rotate the shaft 109. This causes the release of a latch 113 (Fig. 7) which holds a member 114 rigid with the slide 5 so as to allow the latter to be moved by a spring 112 to a cigarette-releasing position. The cigarettes then fall into the supply hopper 96, 97. A motor M4 driving the belt 14 is switched on by the action of a signal from a photo-electric cell responsive to the discharge of cigarettes from the magazine into the hopper 96, 97. The empty magazine is then transported by grippers 38 to a position 11d in storage zone III. The empty magazine is then displaced in a direction at right-angles to the plane of Fig. 2 by a pusher 46 (actuated by linkage 49, 50, 51 from camshaft 32) to make room for the next-arriving magazine. The grippers 38 are reciprocated on slides 18 and 44 by a connection 37 with the slide 19. The conveyer 66 comprises a member 67 slidable on guide-rods 68 and reciprocated by being connected to endless driven chains 70.

Title: Tufting machines
IPC: D05C15/20
Filed: 1970-06-18
Abstract: 1316585 Tufting machines A N SPANEL 18 June 1970 [25 June 1969] 29687/70 Heading D1G A needle assembly, for a tufting machine, comprises a plurality of split-shank needles, each needle 18 comprising two relatively movable cooperating shanks 18A, 18B which when abutted define an internal eye, one shank (18A) having a thread B engaging shoulder and the one or the other shank having a material piecing point 7. The shanks may be moved apart by engagement of one or two pairs of internal abutments 21U, or (21U), (21L) (Fig. 19 not shown) by fixed or movable cam surfaces 20 or (420) or by engagement by a rotatable cam 448 (Fig. 22). Alternatively the shanks 718A, 718B are mounted on respective mounting members 110A, 110B, which are movable linearly or on members 110C, 110D which are rotatable to open and close the eyes. In the tufing machine of Fig. 1 in operation each needle, with closed eye, passes through the backing L, the eye is opened and simultaneously a length of yarn S is cut off by a pair of rolls 22, 23 and sucked or blown through a tube 19, through the eye or eyes of one or a pair of needles to a movable abutment 26. A single needle produces loop tufts and a pair of needles U-tufts. The eyes are closed and the needles raised pulling the yarn S through the backing to form a tuft. If a single needle is being used the eye is opened when raised to release the yarn. The yarn may be bonded to th backing L and a further backing may be applied. In an alternative tufting machine (Fig. 24 not shown) the tuft yarn is not severed between tufts, clamps (105S) and (105M) being provided to hold each tuft while the next one is being formed.

Title: Calendar mechanism
Inventor: KOCI LUDVIK JOSEPH
IPC: G04B19/253
Filed: 1956-09-28
Abstract: 835,273. Date indicators. SUNBEAM CORPORATION. Sept. 28, 1956, No. 29716/56. Class 106 (4). A clock-driven date indicator which indicates the day, date and month provides for the varying number of days in a month of thirty or thirty-one days, but requires manual adjustment at the end of February. A Y-shaped lever 61 is rocked clockwise by a twenty-four hour cam 46 to the same position each mid-night and advances date. and day dials 35, 36 through pawls 71, 69, while a pawl 84 slides ineffectively on the periphery of a ratchet 51 secured to the month dial 34 unless it is the last day of the month. The ratchet 51 has shallow and deep recesses 53, 54 arranged to correspond with the sequence of thirty and thirty-one day months throughout the year and these recesses serve both to advance the month dial 34 by co-operation with the pawl 84 and to control the advance thereof by co-operation with an L-shaped lever 73 pivoted at 74 on the arm 64 of the lever 61. The lever 73 carries a pin 76 on one side of its arm 75 to engage the ratchet 51 and a pin 78 on the other side of its arm 77 to engage the arm 64. After mid-night the cam 46 gradually allows counter-clockwise return movement of the lever 61 under the influence of a spring 82 and throughout each month the pin 76 engages the outer periphery of the ratchet 51 to limit this movement. The slope of the trailing edge of a deep recess 54 differs from that of a shallow recess 53 so that, whereas, in a short month the pin 76 moves to the bottom of a deep recess 54 as soon as the dial 35 advances to thirty, in a long month the pin 76 rides on the brink of a shallow recess 53, Fig. 3, and only enters it with the advance of the dial 35 to thirty-one, when the pin 49 on the back of the dial 35 rocks the lever 73 counter-clockwise. In this way the return movement of the lever 61 is suitably limited to position the pawls 69, 71, 84 to advance their respective dials 36, 35, 34 appropriately upon the next driving movement of the lever 61. Provision is made for the manual adjustment of dial 35 by a ratchet 85, of dial 36 through its spindle 57 and of dial 34 through its spindle 60, with a further lever 86, having a notch for lifting lever 73 through a pin 90 out of a recess if necessary. In a modification, Fig. 19, a roller 127 on a twenty-four hour gear-wheel 44 co-operates with a cam surface 130 of a driving lever 124, replacing the cam 46 and lever 61; a pawl 140 on a lever 138 pivoted on the lever 124 actuates the day-name ratchet 108; while the tail end of the date advancing pawl 132, in place of the lever 73, co-operates with a large tooth 103a of the date dial 102 in place of the pin 49 to control the advances at the ends of the months.

Title: Method of and machine for producing knitted goods
IPC: D04B11/06
Filed: 1945-11-07
Abstract: 669,972. Knitting. KAYSER & CO., J. Nov. 7, 1945, No. 29732/45. Class 74 (ii). A straight-bar machine is provided with mechanism for carrying out a series of narrowings between two successive courses, each loop transfer being of a distance of at least two needles, so that no needle. has more than two loops on it at any time. The narrowing may be continued until the fabric is half its original width. Rotation of a screw 60 by a ratchet wheel 133 and a pawl moves the narrowing combs 50 mounted on rods 42, 43 attached to nuts 56, 57. The yarn carrier is moved by a screw 71 and a nut 70. The screw 71 is rotated by ratchet wheels 121, 122 and a pawl. A cam 100 on a shaft 2 actuates the ratchet mechanism through levers 102, 105. The relative movement of the screws 60 and 71 can be varied by alteration of the ratchet mechanism. The Coulier mechanism is held inoperative during narrowing by a dog 92 which interposes a cam follower 93 between members 94, 95 on the shaft 2 and moves the shaft from its knitting position to its widthchanging position. In narrowing a fabric by the delivery inwardly of two needle loops (Fig. 10), loops on needles a, b are transferred on to needles c, d. The combs are then moved inwardly by two needle widths to pick up double loops on needles c, d and single loops on needles e, f, these loops being delivered on to needles e, f, g, h, each of which now contains two loops. In an arrangement (Fig. 18) in which the fabric is narrowed by four loops, and in. which when two loops have been placed on a needle those two loops are not further engaged by narrowing points, the six loops a, b, c, d, e, f are transferred to needles c, d, e, f, g, h and the combs are then moved outwardly by four widths to pick up loops c, d and transfer them to needles e, f. Specification 659,792 is referred to.

Title: Bonding of resin compositions to surfaces
Inventor: GURNEY WILLIAM ARTHUR
IPC: C08J5/12
Filed: 1952-11-25
Abstract: A composition comprising a resin based on vinyl chloride or vinylidene chloride is bonded to a surface by applying to the surface a bonding agent for a copolymer of butadiene and acrylonitrile, interposing a film of a copolymer of butadiene and acrylonitrile between the bonding agent and a mass of the halogenated resin, and heating the assembly under pressure.  The butadiene-acrylonitrile copolymer may contain vulcanizing ingredients and the heating is then performed under such conditions that it is vulcanized.  Surfaces to which the resin may be so bonded include those of most metals, e.g. ferrous metals, nickel, chromium, manganese, magnesium, aluminium and other metals which are electropositive with respect to hydrogen, and their alloys, wood, resin-impregnated asbestos products, laminated resin-impregnated paper, nylon and graphite blocks.  The bonding agent may be one of those described in Specifications 719,630 and 733,557, [both in Group V]; if the surface is that of a metal electropositive to hydrogen it may be treated with a solution e.g. of ferric chloride ferric sulphate or stannic chloride, dilute nitric acid or aqueous prosphoric acid or oxalic acid which forms an oxide or insoluble salt of the metal, or be subjected to anodic oxidation, and a bonding solution comprising a polyisocyanate or polyisothiocyanate e.g. phenylene diisocyanate, hexamethylene di-isocyanate, ethylene diisocyanate or tri-phenyl-methane triisocyanate, applied thereto.  For metal, wood and other materials generally bondings agents as described in Specification 679,369 [Group V], comprising a heat hardenable aldehyde resin, e.g. a phenol-aldehyde or urea-aldehyde resin, coated with an organic polyisocyanate or polyisothiocyanate, may be used; for steel, a layer of heat-hardenable phenol-aldehyde resin alone is satisfactory.  The halogenated resins may comprise polyvinyl chloride, copolymers of vinyl chloride with other unsaturated compounds such as vinyl esters of organic acids; also copolymers of vinyl chloride and vinylidene chloride, butadiene, chloroprene or isoprene.  Vinyl chloride resin compositions as described in Specification 726,667 [Group VIII], or as sold under the Trade Name "Tygon" are advantageously used.

Title: Bidirectional shaft positioning means
IPC: G05D3/12
Filed: 1956-10-01
Abstract: 818,397. Electric selective signalling systems. COLLINS RADIO CO. Oct. 1, 1956 [Dec. 28, 1955], No. 29884/56. Class 40 (1). A shaft positioning system has bi-directional shaft positioning means. As described, a controlled shaft 14 is capable of sixteen discrete angular positions 0 to 15 which are remotely set by a control knob 11. The control knob 11 operates cam-actuated single-pole double-throw switches 16- 19 in the binary code as described in Specification 660,939. The shaft 14 operates a similar set of switches 26-29 connected to the first set through polarized relays Y 0 -Y 3  over lines 2<SP>0</SP>-2<SP>3</SP>. If the shaft 14 is in position p and the control knob 11 is set to a different position q, current will flow in the line corresponding to the most significant binary digit difference between the binary representations of p and q and the direction of current flow will be forward in the " F " direction if the control switch end of the line is grounded corresponding to a binary " 0 " and the controlled shaft end is connected to the power source S corresponding to a binary " 1." This occurs when q is greater than p, in which case the corresponding polarized relay YO-Y3 switches its contact to the left, and since the relays of higher order have their poles serially connected to ground a current flows through the armature winding W F  to drive the motor 15 and hence the shaft 14 in a forward direction until the shaft-driven switch changes over whereupon if there is a digit difference in the next lower binary order the drive is continued. This process continues until coincidence is obtained. If q is less than p, the shaft 14 is driven reversely since the winding W B  of the bi-directional motor 15 is energized. The embodiment illustrated in Fig. 2 (not shown) employs wafer switches of the type described in Specification 660,939 for the single-pole double-throw switches and uses non-polarized relays so that D.C. of either polarity may be employed. The embodiment illustrated in Fig. 3 (not shown) employs wafer switches for the single-pole double-throw switches and the direction of motor rotation is controlled by a double-triode tube the appropriate triode of which is fired in accordance with the direction of current flow in a resistance matrix. A single field winding motor may be employed by connecting the motor between the triode anodes. Reference has been directed by the Comptroller to Specification 796,316.
