Title: An attachment for chasing threads on horizontal lathes
IPC: B23G1/02
Filed: 1956-04-09
Abstract: 809,467. Screw-cutting attachments for lathes. CICCARELLI, D. P. April 9, 1956 [April 8, 1955], No. 10697/56. Addition to 764,926. Class 83 (3). An improvement in the thread-cutting attachment of the parent Specification comprises a sliding spring-returned cam-bar 9, Fig. 3, for operating the transverse tool-carrying slide, and an adjustable automatic tool-advancing device for increasing the depth-of-cut. The bar 9 is arranged in guides 9a in the longitudinal slide of the attachment, and is spring-urged towards the right. A roller 8 on one end of the bar is engaged by a lip 4a, underneath the main-feedcam, to withdraw the tool-slide at the end of a cut. The other end of the bar has an integral wedge-piece 10 which engages a slot 9b in the transverse-slide to effect withdrawal. Automatic feed.-One form comprises a stop 28, Fig. 2, on the attachment-bed adapted to be engaged, on return of the carriage, by a depending member 21 pivoted to a cranked-lever 20 and engaging, in this direction of motion, a lug 20a on the lever. The latter is thus turned clockwise and a pawl 23 on the other arm of the lever moves a ratchet-wheel 19 to effect toolfeed. The ratchet-disc is geared through bevels 17, 16, Fig. 3, to rotate a cam-disc 15a which engages a peg on the transverse-slide to move the latter. A shrouding-device 25 is adjustable by hand to vary the effectiveness of the ratchetpawl and adjust the feed-step. The ratchetwheel may also be turned by hand. The ratchet-teeth extend only part way around the periphery of the wheel so that the feed-action stops after a predetermined amount of feed. A second form of automatic-feed-device comprises a plunger 34, Fig. 5, slidable against a compression spring 36 in a bore arranged tangentially to a ratchet-wheel 32 secured to the transverse-slide 7. The plunger carries a pawl 35 which moves the ratchet-wheel on outward movement of the plunger by the spring. The latter is compressed by the plunger striking an adjustable-stop 38 on the bed when the carriage 6 reaches the end of its forwardtraverse. The back of the ratchet-wheel is provided with a helical cam which engages a stop on the carriage to effect the transversefeed. In an alternative embodiment of the invention, a similar transverse-feed-device to that last described is used, but the longitudinal traverse is effected by a screw 41, Fig. 8, engaging a roller 43 on a lever 44. The latter is moved automatically to disengage at the end of the braking-stroke, by a trip-arrangement, and the carriage is returned by a spring 13. The return is cushioned by a plunger 59, attached to the carriage, entering a cylinder 58 secured to the base and having an adjustable airescape valve 61.

Abstract: 414,187. Valve circuits for wireless reception. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and KINROSS, R. I., 74, Palace Gardens Terrace, Kensington, London. April 10, 1933, No. 10705. [Class 40 (v).] The damping of a tuned circuit is varied in accordance with signal strength to effect automatic gain control. As shown, the intermediate frequency tuned circuit 1, 2 feeds an amplifier 4 and second detector 9. A twoelectrode rectifier 17 in series with the portion R2 of a potential divider R2, R3 and the detector cathode resistance R1 is shunted across the circuit 1, 2, the potentials due to R2 and R1 being approximately balanced when no signal is being received. When a signal is applied to the detector the current in resistance R1, falls and the anode of the rectifier 17 becomes positive, current passes therethrough and the circuit 1, 2 is damped to reduce the amplification. By adjustment of resistances R1-R3 the control may be delayed to any extent and the range of control varied. The control may be applied to other tuned circuits or to vary the grid bias of other amplifying valves, control potentials being taken from the terminals a, b connected to the rectifier.

Title: Improvements relating to the dyeing of cellulosic textile material with vat dyestuffs
Inventor: KILBY WILLIAM
Filed: 1958-04-08
Abstract: Cellulosic textile materials are dyed with vat dyestuffs by impregnating the material with an aqueous suspension of an acid leuco vat dyestuff produced by treating an aqueous suspension of the vat dyestuff with thiourea dioxide at elevated temperature and under neutral or acid conditions and, while the dyestuff in the material is in the acid leuco form, treating the material with an alkaline liquor so as to convert the dyestuff in the material to the alkaline leuco form.  Fixation of the dyestuff is preferably completed by passing the material through a molten metal bath, as described for example in Specification 620,584, in which case the alkaline treating liquor, e.g. caustic soda solution or a solution of caustic soda and sodium hydrosulphite, floats on the molten metal at the entry to the bath. The acid leuco vat dyestuff suspension, prepared for example by heating an aqueous liquor containing the vat dyestuff, thiourea dioxide and disodium hydrogen orthophosphate, is preferably applied from a padding mangle.  The process may also be applied in association with those described in Specifications 661,086, 663,066, 665,454 and 681,983. Examples are given.
