Title: Atomic frequency standard
IPC: H01L41/00
Filed: 1974-04-02
Abstract: 1448952 Atomic frequency standards E JECHART 2 April 1974 [5 April 1973] 14552/74 Heading G6P An atomic frequency standard comprising a cell 2 containing an alkali element, and a spectral lamp 1 for illuminating the cell 2, has two isotopes of said alkali element in said lamp 1 and/or said cell 2, the ratio of said isotopes to each other being different from the natural abundance isotope ratio by an amount selected to produce a desired dependence of the ressonant frequency of the cell 2 on the intensity of light from the lamp 1. As particularly described, the cell 2 is arranged in a cavity resonator 4 excited to HF oscillation by a quartz oscillator 5. The output of a light-receiver 3 serves to adjust the oscillator 5 to the resonant frequency of the cell 2 which is arranged in a static, homogeneous magnetic field produced by Helmholtz coils 9. The cell 2 is filled with a natural abundance isotope mixture of rubidium and a buffer gas and the lamp 1 contains a mixture of two parts natural rubidium and one part Rb 87 so that Rb 85 and Rb 87 are then present in approximately the same weight ratio. This produces substantial independence of the frequency of the cell from the light intensity of the lamp. In alternatives, the lamp may contain only Rb 87 and the cell Rb 85 and Rb 87 with a greater portion of Rb 85 than corresponds to the natural abundance isotope ratio; or potassium may be used as the alkali element.

Abstract: 711,968. Coils for dynamo-electric machines; transformers and inductances. FOSTER TRANSFORMERS, and BAGNALL, R. I. June 19, 1952 [June 19, 1951], No. 14554/51. Classes 35 and 38(2) [Also in Group XXII] An on-edge coil is made from a metal strip which is coiled by a presser having a curved transfer surface extending arcuately between the plane of the strip travel towards the coil and the plane of the strip as laid in the formation of the coil. Fig. 1, shows a cylindrical mandrel D carrying a draw ring ZR having a longitudinal guide slot one wall of which ends in an arc surface which deflects the strip from the straight to the curved form. Fig. 7 shows the mandrel D, a counterring GR which rotates with D and to which one end of the strip is secured, and the draw-ring ZR. A machine for the production of on-edge windings is shown in Fig. 8. The draw-ring here comprises the forward flange 26 of a presser member 25 which is slidable in a cylindrical member 24 and also on a mandrel 31. A gear box 33 rotates a shaft 32, a plate 35 (serving as the counter ring GR) and the mandrel 31, the end of the strip 19 being secured to the plate 35 by a screw 36, Fig. 11 (not shown). The strip 19 which is to be coiled is fed by a spool 18 through an adjustable clamp 20, under a guide roller 24' and finally through a longitudinal guiding slot 29 in the presser member 25. The latter is subjected to an axial pressure to the left by means of a rope 42 having a weight 44. The rope 42 tranverses a guide pulley 43 to which it is fixed by a clamp 43a. Fig. 14, shows how the pull exerted by the weight 44 is relieved when the required number of turns of the coil is reached. The winding device is also applicable to the production of non-circular, elliptical or rectangular coils.

Title: Improvements relating to the damping of oscillations of traverse arms of high tension electric cable masts
IPC: H02G7/20
Filed: 1927-06-07
Abstract: 280,458. Berg, F. June 7, 1927. Systems of supporting cables.-Relates to a method of damping oscillations which may occur when a sudden overload is applied to the transverse arm of a mast for supporting high tension cables, as, for instance, when a cable breaks. According to the invention, the arm b, b<1> is pivoted to the top of the mast and elastic members such as springs d, d<1>, are interposed between the mast and the arm. A shock caused by the breakage of the cable is first absorbed by the inertia of the arm and is then transmitted gradually to the mast and is diminished by the springs. Instead of the arm being in one piece, it may consist of separate arms, each pivoted to the mast and connected to it by springs. Beams may be secured to the mast to stop the arm when it swings beyond a pre-determined angle, and bolts securing the beams to the mast may be arranged to shear when excessive torsional forces are applied to the arm.

Abstract: 1469051 Blow moulding OWENS-ILLINOIS Inc 14 April 1975 [16 April 1974] 15226/75 Heading B5A A plastics article 82 is blow moulded in successive preform blowing and final article blowing moulds, 16 and 31, using the same blow tube 60 which is mounted on a turret 45 rotatable to convey the blown preform 96 between the two blow moulds. The preform mould 16 is closed about an extruded parison 11 which is severed by a knife 29. The tail flash is removed by plates 28 and the mould assembly is moved obliquely to lie under a cylinder 70. Downward displacement of the piston-rod 73 in the cylinder 70 forces one of the blow tubes 60, which are mounted through each end of arms 46, 47 of the turret 45, into the neck of the parison in the mould. A flange on the blow tube severs excess neck flash. Air is supplied through piston 73 to the blow tube 60 to inflate the parison, the mould 16 is opened, and the piston-rod 73 is retracted to allow a spring in the arm 46 to raise the blow tube 60 with the preform 96 thereon clear of the mould. The arm 46, 47 is rotated by a driven shaft 40 to bring the preform to the final blow mould 31. A member 83 is brought into engagement with the top of arm 47 by the closing of the mould and supplies air to the blow tube to inflate the preform. In Figs. 6 and 7 (not shown) blow tubes are mounted on each of four arms (110) so that 90 degrees rotation of their support shaft (101) brings a blown preform 96 to an intermediate station for cooling in the air or enclosure in a heating or cooling chamber. The arms (110) are raised to lift the preforms clear of the mould during rotation by a cylinder (102) acting on the rotary shaft (101).

Abstract: 704,997. Multi-gap cold-cathode tubes. STANDARD TELEPHONES & CABLES Ltd. June 28, 1951, No. 15363/51. Class 39(1) [Also in Groups XL(b) and XL(c)] A multi-gap gaseous discharge tube comprises an anode 3 and a mica member 7 each in the form of an annular plate, and a plurality of radial metallic screens 4 electrically connected to the anode and dividing the space between the anode and the mica member into ten sections each having a cathode 1 and a trigger electrode 2 mounted on the mica member 7. A priming electrode 9 projects through the central aperture 8 in the anode 3 and is connected to a positive potential intermediate the anode and cathode, potentials and serves to prime all the gaps. An alternative priming arrangement comprises a pair of ring-shaped electrodes surrounding the electrode assembly and priming each gap via a hole in an insulating screen. The tube is used in a circuit arrangement wherein each trigger electrode is connected through a tuned circuit and a transformer to a common input terminal and each cathode is connected to an individual output terminal. An input signal of a certain frequency causes one gap to fire and an output signal is obtained at the output terminal connected to the cathode of that particular gap. An input signal of another frequency causes another gap to fire and the first gap is extinguished by the action of a common anode load resistance. The circuit can thus be used as a telegraph distributer (see Group XL(b)) or to translate a frequency modulated signal into a number of discrete steps (see Group XL(c) ).
