Title: Method for the production of a seamless tubular wire filled with a powdery material
IPC: B23K35/40
Filed: 1967-11-23
Abstract: A tubular wire, particularly a welding wire, filled with a compressed pulverous material is formed by tightly winding a seamless or welded tube on to a core, which is shaken on a shaker table 13 whilst a predetermined quantity of pulverous material is introduced into the open end of the tube, after which the tube is drawn through at least one die to further consolidate the filling powder by reducing the tube external diameter without modifying the wall thickness and is then further drawn to reduce the external diameter and wall thickness of the tube, the compacted pulverous material precluding reduction of the tubes internal diameter. In an embodiment a 50 m. length iron tube is internally shot-blasted, degreased, annealed and drawn through a die on to the drum. After the tube has been filled from a container 19 with the filler material comprising deoxidizing and alloying substances, slag formers and iron, it is drawn through two dies, passed through a chemical cleaning bath and finally electroplated with copper. The tube may be annealed between drawing operations and may be coated with a corrosion inhibiting layer.

Title: Vehicle steering mechanisms
IPC: B62D7/22
Filed: 1967-12-14
Abstract: In steering mechanism for an industrial truck having a steering shaft 4 rotatable in a fixed tubular column member 5, a spring brake 6 associated with lost-motion connecting means between the shaft 4 and steering gear 1 is arranged to allow rotation of the shaft 4 for actuating the gear 1 but to prevent rotation of the shaft due to reverse actuation of the gear 1 caused by shocks exerted on the steerable wheel or wheels of the truck. A spigot 8 on the input member of the gear 1 carries a transverse pin 18 projecting into holes 9 in a collar 7 secured to the shaft 4, the holes 9 being larger than the pin 18 to permit limited lost-motion between the collar and the spigot. The brake 6 comprises a close-coil spring 10 which is closely fitted within a fixed housing 10 and has at mid-length a recess 22 engaged by a tag 12 on the pin 18, and near each end a recess 15, 16 engaged by a C-member 14 located in a groove 17 in the collar 7. When reverse actuation of the gear 1 tends to rotate the spigot 8 relative to the collar 6, one half of the spring 10 is expanded to grip the interior of the housing 3 and prevent such rotation.
Patent ES-351041-A1 (ES)
Title: Hybrid transformer
IPC: H04B1/58
Filed: 1968-02-28
Abstract: The balancing network of a two-to-four wire hybrid transformer circuit is automatically adjusted in accordance with error signals which are derived from signals in a narrow frequency band extracted from the send pair and the receiving pair. Fig. 2 shows one embodiment in which the balancing network for the hybrid circuit includes variable resistors R 1 and R 2 which are adjusted in accordance with error signals derived by filtering from the incoming signals on line 3 frequencies of, e.g., 800 c.p.s., by filter F1. The output of filter F1 is applied to a phase shifter 6 in order to obtain signals in quadrature which are applied to multipliers 7 and 9, to the other inputs of which are applied the signals selected from the outgoing line 4 by the filter F2, which is tuned to the same frequency as filter F1 The output of the multipliers is integrated in integrators 8 and 10 and the resulting signals adjust the values of the respective resistors R1 and R2, which may be field effect transistors, Fig. 3 (not shown). The integrator output signal are representative of the echo signal fed from the receive line to the send line via the unbalanced hybrid circuit. Signals from the subscriber's line 5 have no effect on the integrator outputs since they do not reach the input of filter F1 due to the presence of amplifier A1 while components of the subscriber's line signal which pass through filter F2 are uncorrelated with the signals from filter F1 and do not therefore produce an output from the integrators. In a modified system, Fig. 4 (not shown), the input of filter F1 is connected across the balance network since no signal from the subs line 5 reaches this point. In an alternative arrangement only one error signal is derived, and the resistors R1 and R2 are adjusted simultaneously, Fig. 5 (not shown).
