Title: Label printer
IPC: B41K3/04
Filed: 1966-10-21
Abstract: 1,121,576. Label printer. DENNISON MFG. CO. Ltd. 21 Oct., 1966 [22 Oct., 1965], No. 47183/66. Heading B6C. A printer comprises a platen, a printing head, rotary motive means including a slip clutch for moving the printing head back and forth between the platen and a retracted position once during each recurrent cycle, an abutment on the motive means, a movable stop co-operating with the abutment, and means for introducing the stop after a predetermined number of printing cycles. Fig. 2 illustrates a printer according to the invention in which a frame 1 contains a roll of tag stock T fed by a pawl 3 to a platen 4, each successive tag being printed by a reciprocating printing head (6) mounted on a slide 7 actuated by linkage 8 connected to an eccentric disc 10 fixed to one side of gear 11; the centre of disc 10 is located at 13 being displaced from the centre 14 of gear 11. Thus motor M through the agency of gear 16 on shaft 17 drives gear 11 and causes the printing head to move back and forth and simultaneously, via arms 23 and 21 operates feed pawl 3. A disc 24 is mounted on shaft 17 and has a shoulder engageable with a stop 27 controlled by electromagnet 28. Fixed to the gear 11 are two further discs (26) and 31 whose peripheral radii are substantially the same as that of gear 11 for most of their circumferences; however disc 31 has a shoulder engageable with spring stop 32 held against the disc by its resiliency, and the disc (26) has a portion of reduced radius (Figs. 1 and 3 not shown). In operation, the motor M is started and a switch (47) is momentarily closed to energize the electromagnet 28; this moves stop 27 out of engagement with disc 24 permitting the motor to drive shaft 17 through the slip clutch (29). When the magnet is de-energized after the momentary closure of switch (47) the stop 27 which rides on the periphery of disc (26) is held out of engagement with disc 24 until the gear 11 has nearly completed one revolution at which times, the reduced radius portion of disc (26) reaches the stop 27 and allows it to move into the path of the shoulder on disc 24 causing the clutch to slip and bringing the machine to a halt; stop 32 engages disc 31 continuously and prevents retrogressive movement when the stop 27 prevents foward movement. If more than a single printing is desired, a cam (53) is set to the required number, thus closing a switch (53) which operates a holding circuit for electromagnet 28; the motor M and switch (47) are operated as before, and a counter 39 counts the number of reciprocating movements of slide 7 through arms 41 and 42, and also moves the cam 53 back towards its zero position; when cam 53 reaches this position, switch (53) is opened and the holding circuit for electromagnet 28 is broken, thus allowing stop 27 to halt the machine.

Acrylonitrile polymer fibres having whiteness stability and receptivity to disperse and cationic dyestuffs are prepared by treating an extruded fibre composed of a polymer or a polymer blend containing at least 80%, but less than 100%, by weight of acrylonitrile units and not more than 20%, but more than 0%, by weight of units of at least one other ethylenically unsaturated monomer of which one contains at least one dissociable acid group (e.g. -SO 3 H, -OSO 3 H or -COOH), with an aqueous solution of an alkali metal or ammonium salt of an inorganic acid, said solution having a pH of 2.0-4À0 and being used in such an amount that 75-95% of the dissociable hydrogen atoms of the extruded polymer are replaced by alkali metal atoms or ammonium groups. Fibres containing sulphonic acid groups may comprise units of an acid such as an alkenylarylsulphonic acid, vinyl-sulphonic acid, allyl sulphonic acid or methallylsulphonic acid. In addition to the acrylonitrile and acid units, the fibres may also contain other monomer units, e.g. alkyl acrylates or methacrylates, methacrylonitrile, vinyl or vinylidene chloride, acrylamide or methacrylamide, N-methylolacrylamide, methyl vinyl ketone, vinyl carboxylates, styrene and methylstyrenes. The fibres are preferably obtained by a wet-spinning technique from solutions of the polymer in concentrated aqueous thiocyanate. The pH of the aqueous salt solution used for treating the fibres is adjusted to the desired value by addition of an inorganic or organic acid. In an example, fibres of an acrylonitrile-ethyl acrylate-methallylsulphonic acid copolymer are treated with an aqueous solution containing nitric acid and sodium sulphate, and then dyed with p-aminobenzene (a disperse dye).

The position of the slide 20 relative to the frame, and hence the position of a workpiece W relative to the tool T, is adjustable by a screw 24 and by a toggle assembly 36. The screw 23, Fig. 2, which is rotatable by a work and worm-wheel 30, 28 enables the initial position of the slide to be set, whereas the toggle assembly provides feeding movements of the slide during a working operation. The toggle assembly includes a lever 36 which is coupled to the main frame through a pivot 38 and the screw 24, and coupled to the slide through a link 40. One end of the lever is positionable by a cylinder assembly 46, while the other end is movable in response to the position of a roller 58 on an indexable cam 60. For a rolling operation, the work-table 96 needs only to move vertically, but the tool T is adjustable about a vertical axis A relative to the frame portion 18. A cam 60 of smooth profile is employed, the cam being rotatable by a rack 84 and cylinder unit 88. For a shaving operation, the work supporting table 120, Fig. 8, is of more complex form, and a stepped cam 60 is used. The cam is rotatably indexed by a pawl and ratchet mechanism and is rotatable to its initial position by the rack 84 and cylinder unit 88. Alternatively, a composite cam having both a stepped portion and a smooth portion may be employed. The table 120 is formed with a base 122 which is rotatably adjustable about the axis A, and a carriage 126 slidably mounted on the base. The carriage is slidably moved by a motor driven screw 140. A work-table 152 is mounted on the carriage both for pivotal movement about a horizontal axis 153, and for rotatable adjustment about a pin 150. The pivotal movement allows gears with crowned teeth to be produced. The construction of the table 120 permits axial traverse, underpass, and diagonal traverse movements to be made.

Title: Improvements in or relating to hydraulic cushion for dies
IPC: B21D24/02
Filed: 1964-12-08
Abstract: 1,074,240. Presses. DI-DRO ENGINEERING CO. Dec. 8, 1964 [Jan. 6, 1964], No. 49883/64. Heading B3H. [Also in Division G3] A press 10 having a crank-operated die 18 and a fixed die 22, includes a die pad 24 for cushioning the impact of die 18 without offering too great a back pressure. Beneath the pad 24 are positioned two pistons 28 which are hydraulically connected through a back pressure relief valve 32 with a fluid reservoir 36 at relatively low pressure, the valve permitting fluid to flow from cylinders 26 back to the reservoir 36 when a predetermined pressure is exceeded. In operation, the increase in pressure beneath the pistons 28 during a working operation is transmitted through a conduit 30 to the valve 32. If the pressure exceeds a predetermined value, a pilot valve 100 is lifted off its seat, against the pressure of an adjustable spring 102, by the fluid pressure, thus allowing fluid to pass into passages 106 and 108. Should the pressure in the cylinders 26 exceed a second predetermined value, the pistons 120 and 66 of a pair of unloading valves are lifted by a pressure differential against spring bias to open ports 110, thereby by-passing fluid from the high pressure side of the system to the low pressure side. A one-way ball check valve 54 is biased by a light spring 56 to allow fluid to pass only from chamber 48 to passage 44. A piston 86 and a bore 84 form an expansible chamber, for reducing the back pressure on the unloading valves, the piston being raised, by an increase in the fluid pressure, against an adjustable stop 92, the top side of the piston being open to atmosphere or alternatively to the supply pipe 34 from the reservoir.

Abstract: 1362874 Suede - like materials INMONT CORP 4 Nov 1971 [4 Dec 1970] 51300/71 Heading B2E [Also in Divisions B5 and C3] A process for the production of suede-like materials comprises forming on a backing a layer of deaerated polyvinyl chloride plastisol containing heat-decomposable blowing agent and heating the layer to form a fused layer containing substantially parallel cells which are elongated in a direction vertical to the place of the layer and severing the exposed ends of the cells to expose the vertical cell walls. The layer may be of thickness equal to a single layer of cells. The volume of the blown layer may be 2¢-5 times that of the unblown layer. The surface of the layer opposite to the backing may be in contact with a releasable layer. The backing may be of a woven, knitted or non-woven fabric, e.g. of cotton. A layer of non-foamable polyvinyl chloride may be interposed between the backing and the foamable layer. A volatile high boiling diluent, such as an aromatic hydrocarbon fraction of boiling range 310-345F may be present in the plastisol. Suitable plasticizers and blowing agents are listed. The cell walls may be severed by abrading or by cutting with a knife. In a preferred embodiment the plastisol is coated on a smooth support such as a release paper and gelled (but not blow or fused). A thin layer of non-foamable plastisol is then deposited thereon and the fabric layer is then laid on top. The assembly is then heated to fuse and blow the plastisols. The release paper is finally stripped off.
