Title: Improvements in Drive Units with Self-Starting Synchronous Motors
IPC: H02K7/118
Filed: 1966-06-01
Abstract: 1,153,753. Display turntable. AMPHENOL CORP. 1 June, 1966 [1 June, 1965], No. 24465/66. Heading G5C. [Also in Divisions H1 and H2] A display stand is oscillated by a drive unit including a single phase synchronous motor and a cycling mechanism, (see Division H2). The cycling mechanism consists of an unbroken spiral groove 68 in the surface of one gear-wheel 54, which co-operates with follower 76 mounted from the fixed part of the unit housing. In operation the motor runs in a first direction until follower 76 impacts one of the abutments 70, 72 at the end of the groove when the motor will be stopped and will subsequently rotate in the opposite direction until follower 76 impacts the other abutment when rotation in the first direction will ensue. The stand is considered especially useful for displaying a Christmas tree decorated with electric lights and the rotation through approximately one turn will not cause the flex to become tangled.

Title: Method of preparing niobium base alloy wire
IPC: B21C23/00
Filed: 1964-06-12
Abstract: A method of preparing readily cold workable niobium base alloy comprises cold working a bar of said alloy having a banded grain structure to effect a minimum reduction of 40%, then heating it to a temperaure above its recrystallization temperature e.g. 1000-1400 DEG C. for a period e.g. from 10 minutes to 1 hour, sufficient to convert it to an equiaxed grain structure.  In an example an electrode comprising a sandwich of zirconium and niobium, each of a purity of 99 weight per cent, the sandwich having one part of zirconium to three parts of niobium by weight is melted in vacuo or in an inert atmosphere of argon in an arc furnace to form a 2.75 inches diameter ingot.  After remelting and recasting to aid homogeneity, the ingot is canned with a molybdenum can 0.25 inch thick, heated to 1600  DEG C., hot extruded to a 1.125 inches diameter cooled and the can ground off.  The ingot is cold swaged or forged to 0.75 inch diameter, cleaned by machining, heated in a vacuum furnace at 1300  DEG C. for 30 minutes to cause recrystallization, cooled, and subsequently cold swaged and drawn to a 0.003 inch diameter.  The alloy used comprises 10-65% by weight, preferably 15-50% of zirconium, the remainder niobium.  The electrode may be sintered.  Tantalum or tungsten cans may be used and end walls thereof riveted in place. The extrusion temperature may be between 1200-1700  DEG C.  The cold reduction is preferably 45-65%.  The bar may be finally worked into any size r shape e.g. 0.001 inch diameter wire, strip or sheet form and be used for superconductive applications.

Title: Improvements in or relating to electromagnetic wave transmission systems

Abstract: 1,036,846. Waveguides. WESTERN ELECTRIC CO. Inc. June 20, 1963 [June 26, 1962], No. 24564/63. Heading H1W. Generation of unwanted modes in a waveguide taper is reduced by providing a low-loss dielectric member at a position where the electric field-intensity of the unwanted mode is low and the intensity of the wanted mode is high. The invention may be applied to wave guides designed for transmission of the circularelectric TE 01  mode having tapered transmissions designed according to the methods described in Specification 883,179 and in the article " Circular Waveguide Taper of Improved Design," published in the Bell System Telephone Journal, July, 1958. Such a taper 12 is provided with a dielectric sleeve 13 supported, e.g. by dielectric discs 14, 15. Suppression of the TE 02  mode is achieved if the average radius b of the sleeve at a point is related to the taper radius a at that point by b/a=k 1 /k 2 , where k 1  and k 2  are roots of the Bessel junction of the first kind and order and are equal to 3À832 and 7À016 respectively. The thickness of the sleeve may be constant or may vary as 1/a. A further sleeve may be added, designed to prevent generation of the TE 03  mode. The tapers may consist of helical waveguide as described in Specification 883,439. The Specification contains a theoretical discussion of the invention.

Abstract: 1497301 APC systems; radio navigation NAVIDYNE CORP 9 June 1975 [17 June 1974] 24625/75 Headings H3A and H4D An APC loop suitable for use in a radio navigation system and for deriving a continuous low-noise signal from an intermittent noisy signal comprises a phase detector 12, a controlled signal generator 22, a generator 28 producing a frequency at least one hundred times that of 22, and an arrangement 26, 34 for combining the outputs of 22, 28 to form a reference signal for the detector 12. A pulse deletion circuit 26 (Fig. 3, not shown)modifies the generator 28 output in dependence on the output of 22. The loop may include a switch 18 synchronized to operate with the appearance of a periodic input signal and a lead lag compensation network 20 also functioning as an integrator. In systems such as Decca, Loran C and Omega, radio signals received from several ground transmitters are tracked and phase compared to calculate the position of the receiver with the aid of charts. Phase comparison between two such input signals occurring at differing instants may be obtained (see Fig. 5) by employing two phase lock loops as in Fig. 1 and by effecting phase comparison between the outputs 1A, 1B of the respective controlled signal generators or outputs 2A, 2B of the respective dividers. By utilizing dividers 34 in the two loops, the input phase difference becomes multiplied when the output of the controlled generators are compared and an incremental phase comparator (Fig. 6, not shown) coupled to a phasemeter including an up down counter may be used.

Abstract: 1326859 Peelable seals for packages TOWER PRODUCTS Inc 26 May 1972 [27 May 1971] 24838/72 Heading B8C [Also in Division B5] A process for forming a peelable seal between plastics articles comprises selectively treating one surface of a film containing a proportion of polyethylene with heat at a temperature of from 515 F. to 575 F. while subjecting said surface to an oxidizing atmosphere containing at least 19% oxygen, cooling the film and then thermally bonding the treated film to the surface of another article containing a major portion of polyethylene. As shown in Fig. 1 a blowextrusion apparatus comprises a hot-melt feed unit 10 for introducing molten polyethylene mixture 12 into the orifice of an annular die 14 which is maintained at a temperature between 515 and 575 F. and wherefrom a cylinder of material issues upwardly through a ring-shaped lip 16 in the die 14. Simultaneously a gaseous inflating medium, containing at least 19% oxygen, for instance air (19 to 22% by volume oxygen) is introduced through a line 18 and into a funnel-shaped outlet 20 disposed centrally within the ring-shaped lip 16 to inflate the hot melt into an elongated cylindrical form. A higher, or lower, temperature of the ambient atmosphere is effective to require a correspondingly smaller, or greater, increment of die temperature. The oxidized inner surface of the film forms peelable seals when bonded in conventional heat-sealing equipment at a temperature between 250-400 F. and preferably at 370 F. for a duration of two seconds to another sheet containing a proportion of polyethylene such as polyethylene-ethylene vinyl acetate copolymers. Figs. 2, 3 show a pair of opposed plies 30, 32 according to the present invention and with at least one of their facing surfaces oxidized, the plies being sealed along lines 34, 36, 40. Figs. 4, 5 show a container wherein the oxidized surface of a film 50 is heat-bonded to an upper flange 52 of a filled container 54.

The optical system 6 is such that the light reflected by mirror 5 covers the entire picture area of the photo-cathode 1. The mirror 5 may be of annular form so that light passing through the centre of lens 4 is effective in imaging the luminous master on to the photocathode. The position of the tube 3 and object 7 may be interchanged and the latter may comprise film images of which are projected on to the photo-cathode during frame blanking intervals only. By making target 8 (including the signal plate) semi-transparent both light beams may be projected on to the photo-cathode 1 through the target, this arrangement allowing the photo-cathode to be made thicker and to be entirely covered, on the surface remote from the target, by a non-transparent conductor so that all points on the photo-cathode are maintained at the same potential, even when illuminated by high light intensities.
