Inventor: HINDLE THOMAS
IPC: B41F17/00
Filed: 1918-08-17
Abstract: 125,302. Hindle, T. Aug. 17, 1918. Printing processes; rotary machines.-A method of printing fabrics consists in passing the fabric into an ordinary calico-printing machine without flattening the fibres, printing, or applying the colour thereto by one or more ordinary pattern engraved or blotch rollers running out of contact with the impression bowl and at a different surface speed from that of the fabric and subsequently removing some of the colour by a plain smooth roller and redepositing the colour upon the fabric. As shown, the fabric enters the machine between the bowl A and a roller a having a surface which will not flatten the fibres of the cloth, and then passes over the surface of one or more engraved rollers b, c, which are preferably blotch rollers having the design in intaglio but printing from the relief parts so that the printed design shows white on a coloured ground. The fabric then passes between the bowl A and a smooth roller d which takes up some of the colour from the fabric and redeposits it upon the fabric. The size of the roller d is such that the design printed by it falls out of register with that printed by the rollers b, c so as to produce a shadowy effect, and the speed of the roller d may be varied to produce different effects.

Title: Improvements in or relating to a tape-dispensing apparatus
IPC: B65H35/00
Filed: 1947-05-20
Abstract: 639,407. Tape-dispensers. DERBY SEALERS, Inc. May 20, 1947, No. 13514. Convention date; June 29, 1946. [Class 18] A pressure-sensitive adhesive tape dispenser comprises a feed roller, to which the tape adheres for the purpose of dispensing, and means adapted to engage the tape on the roller as it is fed from the dispenser to dis-engage the tape from the roller. The tape is engaged by a severing device provided with means for dis-engaging the tape from the device after a length of tape has been severed. As described, the roll 15 of adhesive tape is disposed between two upright plates 11, 12 between which is also mounted a feed roller 17 actuated by a handle 26 through a pawl and ratchet mechanism 21, 24 mounted on the outside of one of the upright plates. The tape is fed over and adheres to the feed roller 17 so that rotation of the roller delivers the tape from the dispenser. Geared to the feed roller 17 is a ratchet wheel 33 mounted between the upright plates and which is positioned to engage a detent 46 supported between two pivoted levers 38, the free ends 36, 37 of which project adjacent each side of the roller 17. A spring 44 is attached to the levers to bias the detent towards the ratchet wheel 33. Upon rotation of the feed roller the ratchet wheel is rotated to impart a reciprocatory movement to the levers to cause the ends 36, 37 to intermittently project above the surface of the roller, which movement dis-engages the tape adhering to the roller and presents a free end of the tape which can be readily grasped. A severing device is positioned above the feed roller and comprises a severing member 48 to which is attached a spring 50, the arrangement being that when a length of tape is severed by pressing it against the edge of the member 48, the spring 50 dis-engages the end of the tape from the member to permit another length of tape to be dispensed.

Title: Improvements in or relating to electric circuit interrupters and arc-extinguishing structures therefor
IPC: H01H9/34
Filed: 1941-10-22
Abstract: 552,774. Arc-rupturing in switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 22, 1941, No. 13580. Convention date, Oct. 29, 1940. [Class 38 (v)] A "deion" structure comprises insulating end plates 35, 37 united by two pairs of insulating side plates 39, 41, the plates 41 being lined with arc-resistant material 45, 43 between the latter of which the arcing contacts 25, 27 separate. The arc is transferred to horns 49, 55 by a series magnetic blow-out coil 59 and side plates 65, 75, and thence to arcing plates 47, 53. During this movement the arc enters the tapering slots 69 in spaced parallel plates 67, preferably of non-gas forming insulating material, the slots being alternately to one side or the other of the vertical centre-line of the plates. The structure comprising plates 67 is in two parts separated by a chimney 79 located just above the point of contact-separation so as to allow escape of the initially-formed arc gases, the chimney being formed over barriers 81 to prevent intermingling of the arc gases rising from the top of the two parts of the plate structure. The effect of the chimney is additionally to force the arc to loop at 82 into the chimney, so stabilizing the arcposition at that point and obtaining a more even distribution of the arc throughout the structurelength. Specification 530,199 is referred to.

Filed: 1936-05-15
Abstract: 472,772. Electric welding. PRESSED STEEL CO., Ltd., and TRIBE, T. F. May 15, 1936, No. 13772. [Class 83 (iv)] In a portable electric fluid-operated welding machine, such as a welding gun, the actuation of an operator's manual control button, lever or switch admits fluid to the electrode cylinder and at the same time to an auxiliary cylinder, the plunger of which thus moves at a predetermined pressure to close contacts in the circuit of a timing device, which also energizes an electromagnetic relay to actuate an armature that co-operates with the control button &c. to hold it in operative position until a weld conforming with predetermined conditions is effected. The supply of air &c. to and exhaust from the electrode cylinder 12 is controlled by a spring returned hand operated valve 14 provided with an enlarged end 33. When the valve is pushed in part of the fluid is byepassed through a port 32 and operates a spring-loaded plunger 25 when the desired welding pressure is reached, to close a switch 28, to bring in the timing device which in turn closes the circuit of an electromagnet coil 19. A spring-returned pivoted armature 20 is thus lowered so as to hold the valve open by means of the trigger 21 should the operator prematurely release the same. When the cycle of operations is completed the coil 19 is de-energized and the armature released to permit the return movement of the valve. In a modification, a rotary tapered plug valve 52 operated by a spring-returned hand lever 51 is used, the end 64 of the armature in this case engaging an extension 65 on the lever to prevent the return of the valve until the required time. The electrodes may be operated by air, oil or water. The timing mechanism or the whole device may be disposed remote from the gun.
