Title: Improvements in the Connection of Subscibers' Lines to a Crossbar Multiselector
IPC: H01H67/26
Filed: 1968-02-15
Abstract: In a cross-bar switch, the contacts of one row are used as the equivalent of cut-off relay contacts whereby the need for such relays is dispensed with. The switch is preferably of the magnetic or mechanical latching type described in Specification 1,148,237. The normallyclosed contacts for the row C are not multipled but are connected individually (C1-C4) to a call detector circuit. When a path from a calling (or called) line e.g. A3 to a junctor has been selected, the relevant cross-point e.g. Pa is closed by operating the select bar S2 and connect bar X3 and at the same time cut-off contacts Pb are opened so as to remove supervision from the line. An additional row bar (not shown) may have its contacts multipled to a common busy tone circuit.

Patent ES-392748-A1 (ES)
Title: Mobile track survey apparatus for determining the track camber
IPC: B61K9/08
Filed: 1971-06-30
Abstract: Two sensing elements each engaged with both rails and spaced apart in the track elongation direction survey the vertical positions of the rails at four points defining a rectangle. An elastically deformable rod interconnects the sensing elements so that a difference in the vertical positions of the rails deforms the rod in response to a vertical movement of a sensing element. The deformation of the rod causes a strain to be set up in the rod and a resistance strain gage on the rod measures this strain and generates an electrical measuring signal proportional to the movement of the sensing element. An electrical measuring signal indicator is connected to the strain gage to indicate the signal.

Patent ES-407788-A1 (ES)
Title: Molding apparatus
IPC: B60B7/00
Filed: 1972-10-11
Abstract: Apparatus for molding a composite styled wheel for use on automotive passenger vehicles and the like, a method of constructing such a wheel employing the molding apparatus and a method of constructing such molding apparatus, wherein a portion of the mold comprises a conventional metal vehicle wheel having a drop center rim secured to a central disc or body having the usual bolt circle holes and a central aperture so that the disc can be mounted on an axle, drum or disc brake assembly. The metal wheel is employed in conjunction with an upper back-up clamp and lower mold part to define therewith a sealed cavity for molding and attaching a three-dimensional contoured plastic overlay, the overlay thus being molded in situ and permanently attached to the outboard side of the wheel in the mold apparatus. Preferably, the wheel forms the upper surface of the mold cavity and a reaction mixture of a urethane elastomer liquid adhesive material is injected or poured into the mold to fill the cavity and contact the outboard surface of the wheel assembly. The urethane material solidifies to form a high density noncellular elastomer body which permanently adheres to the outboard surface of the wheel subassembly. The plastic overlay may also be constructed from a lower density microcellular closed cell urethane elastomer adhesive material. The urethane material is allowed to solidify in the mold cavity and then the mold is opened so that the wheel with the overlay securely adhered to it may be removed from the mold. The overlay may then be painted or otherwise covered with a decorative coating to provide a finished metallic-appearing ornamental wheel. The urethane elastomer thus forms a plastic body having a three-dimensional contour which is permanently attached to the outboard side of the wheel to provide a decorative surface, and the elastomer overlay appears to be an integral portion of the metal wheel.
