Abstract: 1300441 Extruding; piercing WESTERN ELECTRIC CO Inc 25 Feb 1970 [25 Feb 1969] 9065/70 Headings B3H and B3P [Also in Division B5] A metal shaping apparatus comprises a die 12 and a plunger 17 to confine a billet 23 so that it completely fills the die and a mandrel 19 which deforms the billet as the die, plunger and mandrel are moved relatively. The shape of the billet is changed by this movement but the movement is such as to keep the billet volume constant. Preferably the mandrel is fixed and the die and plunger are moved downwards together but at different speeds. The die has a textured or helically grooved wall to apply frictional pressure to the billet. In an embodiment, Fig. 2, the mandrel 59 is fixed to a platen 43 to which a cylinder 42 is mounted. A piston vessel 63 is displaceable in the cylinder and houses the die 108. The plunger 109 is arranged to enter the die through a bore 89 in a cup-shaped cap 69 for the vessel. The plunger has a plate 144 to receive the billet 148 to load it into the die. The die is made of segments (112), Fig. 5 (not shown), urged outwards by ring springs (122) and inward during shaping by fluid pressure in an annular chamber 117. The piston vessel 63 is initially moved downwards by fluid pressure in a chamber 98. The billet is then moved into the die bore 129 and pressurized against the fixed mandrel 59 by the plunger. The vessel 63 and the plunger 109 are then moved towards the mandrel by fluid pressure to shape the billet while keeping its volume constant. The billet may be preshaped to fit into the die and is preferably 98% nickel. After forming it may be heat treated and machined or sized. A lubricant such as indium may be used. The bore may be polygonal as determined by the mandrel and the outside cross-section may be elliptical. The base of the cup-shaped article may be removed by cutting to form a tube. The material of the billet may be metal, a slurry, comminuted or granulated material.

Abstract: 1,098,754. Automatic exchange equipment. SIEMANS A.G. March 4, 1965 [March 4, 1964], No. 9188/65. Heading H4K. A subscriber's push-button digit sender transmits signals in addition to each digitsignal to indicate depression and release of each push-button. In the arrangement shown in Fig. 1 the additional signals generated at the sub-set N1 are provided by a momentary opening of the line loop. Lifting the handset closes contacts 1GU to complete the line loop and connect the line to an exchange receiving circuit VE. The supply of battery potential to the loop operater relay A1 which by means of its now open contacts 4a isolates the dialling unit S from both the wires. Upon actuation of a dialling push-button T1-T10 common contacts 2TT and 3TT operate, to isolate relay A1, but due to capacitor C, it is slow to release and contacts 4a, momentarily remain open so opening the line loop path through contacts 3TT, dialling unit S and relay A2 to indicate depression of the push-button. The subsequent operation of relay A2 upon completion of the loop isolater relay A1 and the speech circuit M/T from the line at contacts 5a2. With the release of the push-button, contacts 3TT open and 2TT close, but the loop is again momentarily opened at contacts 5a2 of the slow to release relay A2. At the exchange the first momentary break in the loop disengages relay S in the receiving circuit VE which by means not shown operates relay CA to connect the receiving relays in unit WE to the line. Relay N operates to open the line path to subsequent stages. After receiving the digit signal from the dialling unit S the unit WE disconnects itself after a time delay by short-circuiting relay CA. The opening of the line indicating release of the button again disengages relay S to break the holding circuit of relay N, which may also be made to release the unit WE. In another arrangement (Fig. 2, not shown) intended for audio-frequency digit-signalling one of the line wires is grounded throughout the time of depression of the push-button to effect similar switching as above.

Filed: 1943-06-11
Abstract: 574,423. Autographic registers. WILLIAMS, W. P. (Standard Register Co.). June 11, 1943, No. 9458. [Class 16] [Also in Group XIX] In registers of the kind having record strips in continuous form fed by means of pin-wheels engaging perforations in the marginal edges of the strips, and one or more strips of carbon or other transfer paper fed transversely between the paper strips, the feeding means for the transfer strips comprises a reciprocable device including a ratchet-and-pawl mechanism operable under the control of a projecting member on the pin-wheel shaft of the record stripfeeding means. In the form shown in Figs. 1 to 5, folded record strips 8 are withdrawn from a supply compartment 6 in the casing over individual guide rollers 10 and a writing tablet 4 by a pair of pin-wheels 11 interconnected by a sleeve 12 on a transverse shaft 13. The writing tablet 4 is carried on a pivoted frame part 2, at the rear of which is a curved guide for the record strips. The frame 2 is held in position by a rod 18 thereon engaging latch arms 20 on a rock-shaft 19. The curved guide carries a rock-shaft 22 with arms 23 having rollers 24 which ride upon the periphery of discs 15 attached to the pin-wheels 11. The rollers 24 engage notches 16 in the discs 15 at the end of each strip feeding operation. The arms 23 also carry a hold-down and tear-off blade 26 except for one strip which is led to a receiving compartment 9 and refolded. A shoulder 29, Fig. 5, on the arms 23 co-operates with a latch 30 to hold the arms in raised position when inserting a new set of record strips. Strips of transfer material are interleaved in transverse relation between the record strips and are advanced in successive steps simultaneously with the feeding of the record strips. Rolls 35 of transfer material are carried on shafts 34 journalled in the pivoted frame 2 and have their leading ends inserted between the sets of toothed pinions 40, 44 mounted on shafts 39, 43. The shaft 43 is mounted on spring-controlled arms 41 which yieldingly press the pinions into engagement. The stepby-step feeding of the material is effected by a ratchet-wheel 46, Fig. 3, on the shaft 39 and pawl 48 on an oscillatory lever 47 concentric with the shaft 39 and formed with an end 47<1> projecting into the path of a pin 50 extending radially from a collar 49 on the sleeve 12. Retrograde movement is prevented by a detent pawl 52. An extension 47<11> on the lever 47 enables the strips to be advanced manually. In a modification, Fig. 15, the actuation of the pawl lever 47 is effected by a cam 60 on the shaft reciprocating a pair of racks 61, 63 connected by an idler pinion 62, the rack 63 being formed with a head 64 to oscillate the pawl lever 47. The cam 60 may be formed with one or more lobes. Instead of pinions 40, pinwheels may be substituted to engage marginal punched holes in the transfer material.

Abstract: 514,425. Endless conveyers. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. March 28, 1938, No. 9504. [Class 78 (i)] [Also in Group XVII] Means are provided for detecting when a cigarette is missing from a row of juxtaposed cigarettes fed from a supply towards a packing or wrapping machine. The cigarettes are moved transversely with relation to their longitudinal axes by a catcher band 5 beneath top plates 55 and over a guide 6 into a passage 7. The passage comprises guides 8, 9, which engage the ends of the cigarettes and feed them, still with their longitudinal axes horizontal, on to a table 10. Three sets of guides may feed cigarettes at different levels so that they may be collated in superposed layers and fed forward as described in Specification 514,322. A movable element 23, pivoted at 25 and normally held by a weak spring 28 in the position shown, is disposed behind the cigarettes in the guides 8, 9, and in the path of an air jet projected from a nozzle 31. If the supply of cigarettes fails, the element 23 is exposed to the air jet and is rocked about its axis and causes a mercury switch 29 to complete a secondary circuit which energizes a, solenoid to cause the primary circuit to be broken and the machine is stopped. The band 5 may be continuously driven independently of the main drive of the packing machine, and, when it has fed sufficient cigarettes to fill the guides 8, 9, the member 23 is screened and returns to the position shown under the action of the spring 28. This breaks the. secondary circuit and causes the machine to be restarted. In a modified arrangement, the member 23 may be caused to give an audible or visual signal.

Filed: 1966-03-07
Abstract: Pile fabrics, especially imitation furs, which pile is constructed of fibres of, e.g. cellulose acetate or triacetate, polyacrylonitrile, polyamide or polyester are coloured by applying at least one disperse dye to the ends of the pile fibres and then heating the fabric so that the dye migrates down the pile fibres giving a colouring that is shaded off within the thickness of the pile.  A single dye or a mixture of dyes may be employed especially of dyes having different migration properties.  The dyes may be applied as aqueous dispersions by brushing or spraying or in the solid (powdered) state either uniformly over the whole surface or locally over parts of the surface.  The treated fabric may be dried and then heated at 150-200 DEG C.  An example of dyeing an imitation fur containing 80% acrylonitrile.
