Title: Improvements in and relating to methods of manufacturing electrical resistances
IPC: H01C17/04
Filed: 1943-03-31
Abstract: 566,971. Wire resistances. BAYLISS, H.E. March 31, 1943, No. 21952/44. Divided out of 566,950. Drawings to Specification. [Class 37] ' A wire wound resistance is produced by mounting a former on a supporting mandrel, winding resistance wire tightly on the former, removing the wound former from the mandrel, and subsequently flattening it to produce a wire wound resistance strip, the winding being secured to the former by the application thereto, during or after winding and prior to removal of the former, of a fixative, and the material of which the former is made and the nature of the fixative being such that the wire wound resistance strip is still flexible. A strip of paper is wound spirally round a mandrel and a connecting tail is formed by winding a comparatively thick wire about the former and leaving the twisted ends outstanding. One end of the resistance wire is secured to the tail and the wire is wound on the former, the other end being secured to a second connecting tail. An insulating fixative such as celluloid dope is then applied. The former is removed from the mandrel and passed between rollers so as to flatten it into the form of a strip, which may be wound on a bobbin with interleaving insulating strips or may be sandwiched between two layers of strip insulating material and folded backwards and forwards on itself to form a resistance of small bulk. Cooling fins may be provided between the folds. The finished resistance may be impregnated with a water, heat or fireproof material and may also be sealed in a container which is evacuated or filled with an inert gas. Tappings may be formed by providing tails at appropriate points during winding or by the application of connecting tabs to the flattened strip. Instead of being wound in a single layer, the resistance wire may be wound in multi-layer or pile form. The former may be of other than cylindrical form. According to the Provisional Specification, adjacent turns of the resistance wire may be touching or spaced regularly or irregularly, or with an increasing or decreasing spacing. Adjacent turns may be separated with an intermediate winding. Where adjacent turns of the resistance wire are spaced, the fixative may contain small particles of material to act as spacers between adjacent turns. Tappings may be made from metal bands which, when flattened, are soldered in slots formed in a back extension of the contacts of a contact switch. Reference has been directed by the Comptroller to Specification 560,260.

Filed: 1947-08-08
Abstract: 657,542. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 8, 1947, No. 22078. Convention date, June 8, 1946. [Class 39 (i)] The spring tensioning means at one end of the filament 2 is designed so that the applied tension is constant, predetermined and easily repeatable. The filament is first threaded through triangular holes in the top and bottom support micas 7, 8. One end is attached via an L-shaped connector 14 to a tension spring 15 bent to form two unequal portions at a predetermined angle, in this instance 110 degrees. An anchoring member 16 has two side sections 19, 20 at right angles, and a flap 18 at 20 degrees to the side wall 19. The shorter arm of the spring 15 is welded into a notch 17 punched out of the flap 18, which temporarily secures the upper end of the filament. The connector 12 at the lower end is now engaged in a slot in the support member 13 attached to a lead wire 9, pulled down until the horizontal portion of the spring just moves, and then welded in position. The flap 18 and the short arm of the spring are now closed tightly against side section 19 and welded, thus applying to the filament a degree of tension predetermined by the original angle of the flap 18. The mass of the anchoring member 16 assists in preventing impairment of the spring tension during the valve processing. The member 13 also acts as an interelectrode shield.
