Abstract: 1,102,949. Making electrical connections. AMP Inc. 3 May, 1966 [7 May, 1965], No. 19373/66. Headings B3A and B3Q. Apparatus for joining wires (4, 6), Fig. 1 (not shown), by electrical connectors (2) comprises a die assembly (78, 80, 82), Fig. 5 (not shown), having a slot (74) between its ends co-operating with a shear blade 136 for trimming the wire, an anvil 134 cooperating with the die, feed mechanism 138 for feeding connectors to the anvil, and mechanism 118, 122 for moving the anvil towards the die to trim wire in the slot (74), and crimp a connector on the anvil to the wire. The apparatus is supported from a cable by a frame, as described in Specification 1,102,949, and includes side members 66 (68) formed with slots 108 (114) for guiding a slide 98 carrying the anvil. The slide comprises side plates 100 spaced by blocks 102, 104 through which pass pins 106, 110 running in the guide slots 108 (114). Pivoted on the slide 98 is a bell-crank lever 144, 150 carrying a spring- pressed, feed-finger 138 on a pivot 142. Crimping strokes of the slide carry limb 150 of the lever against an abutment 72 and withdraw the finger 138 to engage the next connector of a strip of connectors, which is similar to that described in Specification 1,102,948, rearward movement of the strip being prevented by springs (147), Fig. 15 (not shown), which engage the leading connector. Operation of the anvil-slide 98 is by a pneumatic cylinder 130, a lever 122 and a link 118. The strip of connectors passes through guides 154 secured to the slide, the connector carrying strips (5), Fig. 12 (not shown), passing through slots (198) in pivoted blocks (192) on opposite sides of the slide. Shearing.-During the crimping stroke, the blocks (192) engage abutments (84), Fig. 13 (not shown), and are turned about pivots (196), thus severing the plastics lateral bridge supporting the leading connector, which is on the anvil. Adjacent each block (192) are shear plates (200), on springs (206), which sever the side strips (5) as they leave the guide slots (198). The ends of wire are trimmed by the blade 136, as described above. Ejectors: articles transferring.-On the outside of the side plates 66 (68) are two pairs of pivoted fingers (158, 160), Fig. 8 (not shown), the wire (4) being placed in a slot (162) in the fingers (158), looped around projections 92 and pulled through the slot 74 to extend through slots (88, Fig. 2) in plastics guides (86). Springs (168) hold the fingers (158) against stops (170), and during a crimping stroke, the guide-pin 106 deflects a spring (174) without moving the fingers (158). On the return stroke of the crimping slide, pin 106 rotates the fingers (158), stripping the crimped connector and transferring it to a position (Fig. 10) in which the wires are engaged by the second fingers (178) and transferred to a collecting fence (190). The spring (174) deflects, allowing the pin 106 to pass, and the second fingers (178) are oscillated by connection to the guide-pin 110 and a link (186).

Filed: 1929-06-26
Abstract: 314,396. British Celanese, Ltd., (Assignees of Blume, W. R., and Dreyfus, C.). June 26, 1928, [Convention date]. Addition to 274,841, [Class 15 (ii), Dyeing, Processes &c. for]. Printing processes.-Matte effects are produced on fabrics made of or containing organic derivatives of cellulose by applying to them locally an effect composition containing a water-insoluble thickening agent, an effect material, and a solvent for the thickening agent, which is a non-solvent for the organic derivatives of cellulose contained in the fabric. The fabric to be treated may contain cellulose esters, such as the acetate, formate, propionate or butyrate, or cellulose ethers, such as ethyl, methyl, and benzyl cellulose; other fibres such as silk, cotton, wool, or reconstituted cellulose may also be present. The effect material may be a white pigment, such as zinc oxide or barium sulphate, or a coloured pigment, and dyes may also be added to the effect composition if desired. The preferred thickening material is cellulose nitrate, which may be dissolved in alcohol and ether, but other materials, such as cellulose ethers, for example, ethyl cellulose, dissolved in benzene or toluene, may be used for printing fabrics containing cellulose esters. Plasticizers or softening agents, such as camphor, triphenyl phosphate, tricresyl phosphate, dibutyl tartrate, diethyl phthalate, and triacetin may also be added to the compositions. The compositions may be applied over the whole surface of the fabric, to produce a fabric. of uniformly dull lustre, or they may be applied locally, for example by printing with engraved or embossed rolls, plates or blocks, or by brushing or spraying through stencils, to produce differential effects. The compositions may be applied to fabrics of normal lustre, or the fabric may be first delustred, for example by treatment with wet steam or hot water. When the compositions are applied locally over a delustred fabric, the untreated parts of the fabric may be relustred by treating with dry steam above 100 C., or by treating with solvents for the cellulose derivatives contained in the fabric, for example with formic, acetic, succinic, or citric acid or sodium, ammonium, or calcium sulphocyanide. Other organic substances, such as aniline, phenol, and aqueous acetone may also be employed. The fabric may be dyed before or after application of the compositions. In an example, a satin fabric composed of cellulose acetate yarns dyed a golden maize colour is delustred by exposing to wet steam, locally printed with a paste containing cellulose nitrate, zinc oxide, ethyl alcohol, ether and a plasticizer, dried, and treated with a relustreing agent containing calcium sulphocyanide and gum or acetic acid and wheat starch thickening. The fabric is then dried and steamed.
