Abstract: 1317594 Winding tyre reinforcements DEERING MILLIKEN RESEARCH CORP 21 May 1970 [22 May 1969] 24727/70 Heading B7C [Also in Division B8] An apparatus for positioning at least one continuous cord on a support surface in a desired pattern to form a tyre reinforcing belt comprises a cord support surface, means for causing an adhesive affinity between the cord and the surface, and means for positioning the cord on the surface and roller-pressing it across the entire width of the pattern for adhesion to the surface. A cord 22, coated with a tacky adhesive is guided to a belt-forming device 16, comprising a rotatable drum 26 with a cylindrical support surface 27 and a cord guide mechanism 30 mounted for reciprocating movement across the surface 27, the drum being driven via gears 42 and the guide mechanism via a cam 40 by a motor 34. The guide mechanism 30 is pivotally mounted on a shaft 49 so that a roller 47 having e.g., a silicone rubber surface can be urged against the surface 27 or withdrawn therefrom. Cord is fed through the mechanism 30 via a guide tube (52, Figs. 3 and 4, not shown) where it emerges adjacent the nip of the drum 25 and roller 47, and is pressed into contact with the surface 27 by the roller 47 as the drum 27 rotates and the guide mechanism 30 simultaneously reciprocates. When sufficient cord has been laid, the guide mechanism is withdrawn from the surface and a solenoid (67) operates to retract a member (55) and draw the cord 22 into engagement with a cutting blade (54); an eccentric roller (61) engages the cord to prevent reverse movement thereof in the guide tube (52). In an alternative embodiment (Figs. 10-12, not shown) the cord is fed between rollers (74) into contact with the pressure roller 47 and surface 27, and is cut by scissor blades (76, 77). Instead of winding the cord directly on to the drum surface a layer of rubber may be placed on the drum to serve as the cord support surface and become part of the final belt.

Abstract: 584,059. Thermionic valve voltmeters. SECORD, A. H., and LANG, G. R. Dec. 13, 1944, No. 25026. [Class 37] A valve voltmeter of the bridge type has one arm containing a valve and two arms each containing a neon stabiliser. Since the A.C. resistance of a neon stabiliser is very low compared with its D.C. resistance the sensitivity of the bridge approximates the mutual conductance of the valve. The valve V1 with its associated resistances R1, R2 form one arm of the bridge, the anode resistance R3 the second arm, and the neon stabilisers V2, V3 the other two arms, initial balance of the bridge being obtained by varying R2. The resistance R3 may be replaced by another valve. The resistance R1 may be switched off after balancing as long as there is a D.C. path for the applied voltage. A resistance R4 limits the current through the stabilisers V2, V3.
