Abstract: 1,099,498. Terminals; junction boxes. P. & B. ENGINEERING CO. Ltd., J. EVENDEN, and H. W. WILLIAMSON. Oct. 8, 1965 [Oct. 10, 1964], No. 41453/64. Heading H2E. A casing 11 housing an electrical device has a terminal 15 located in a recess formed by the extension of two of the walls of the casing, a connection being made through screw 16 to a lead 18 connected to an instrument. The lead 21 may enter as shown in Fig. 1 and be clamped by screws 22 and 23 or may enter from the opposite end of the terminal (Fig. 3, not shown) and be clamped in position by screws entering tapped holes at right angles to the holes receiving screws 22 and 23. In the second position described, panel 24 which slides into a groove in the casing, is removed and the lead enters either between the casing and panel 12 on which it is mounted, or through an aperture in panel 12. Panel 25 holds lead 21 in position, and the panel 25 cannot be removed until the casing is unscrewed from mounting panel 12. In an alternative embodiment (Fig. 4, not shown), the panel 24 may be replaced by a thin sheet integrally moulded with the casing, which sheet may be fractured by a screw-driver when it is required to pass a cable through it. Panel 25 (Figs. 4-7, not shown) may be held in position by a screw in either one of two positions depending on whether or not a cable is inserted at that end of the terminal.

Abstract: 947,533. Transistor amplifier circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 12, 1962 [Nov. 22, 1961], No. 41751/61. Heading H3T. [Also in Division G1] Nuclear particle detection apparatus comprises a particle detector fed by a transistoroscillator E.H.T. generator and an emitterfollower feeding detector output pulses to a connector, the generator and emitter-follower deriving their L.T. supply from said connector through separate low-pass filters. The L.T. source 6 is connected to the end 2 of a coaxial connector 3 through a low-pass filter comprising components C11, R9 and L4. This L.T. supply feeds the E.H.T. generator 5 through the lowpass filter L1, L2, C7, C8 and provides the collector voltage of a transistor J1 through a low-pass filter L3, C9, the voltage being stabilized by a Zener diode D1. The pulse output of a scintillometer photomultiplier which derives its dynode voltage from generator 5 is fed to the base of transistor J1 connected as an emitterfollower. The output pulses from transistor J1 are substantially unaffected by the low-pass filters and pass along connector 3 and through capacitor C12 to a pulse height analyser. In a modification, the resistor R9 may be connected between the other side of C12 and earth. The apparatus may be used for monitoring radioactive chemical plant process streams.

Title: Improvements in or relating to straight bar knitting machines
Inventor: START ERNEST
IPC: D04B11/04
Filed: 1964-10-21
Abstract: 1,118,564. Knitting-machines. WILLIAM COTTON Ltd. 13 Oct.. 1965 [21 Oct., 1964], No. 42833/64. Heading D1C. Prior to the machine latch needles 1 of a straight-bar rib machine receiving their initial course of yarn a series of latch opening points 4 are advanced and engage beneath the latches of the needles whereafter the points are withdrawn and in so doing open the latches. The latch opening points have their ends turned at right angles to their shanks, so that by shogging the point bar holding them sideways, after it has been advanced, the point ends can engage beneath the latches. The point bar 3 is secured to arms 13 mounted to slide in a slideway 12, Fig. 1, and these arms are secured to a lever 17 controlled by a link 18 and cam operated lever 19 to be advanced and retracted at desired times. A latch 26 controlled by a disc 23 determines when the lever 19 is operative. A projection 13a on the arm 13 engages a switch 29 when the arm is fully advanced and this energizes a solenoid 31, Fig. 2, such that through its spring connection with the point bar 3, the bar 3 is caused to shog sideways and engage the inturned ends of its points beneath the latches of the machine needles. The points are then withdrawn simultaneously opening the latches, and when the arm 13 is fully withdrawn the projection 13a engages a second switch 30 which switches off the solenoid whereby the point bar returns to its initial position. Alternatively, the point bar may be shogged by mechanism driven by an electro-magnetic clutch which is controlled by the switches 29, 30.

Title: Method of making magnetic body with pattern of imbedded non-magnetic material
IPC: H05K1/03
Filed: 1964-10-21
Abstract: 1,060,996. Laminates. RADIO CORPORATION OF AMERICA. Oct. 21, 1964 [Oct. 23, 1963], No. 42925/64. Heading B5N. [Also in Divisions H1 and H3] A method of making a magnetic structure, such as a magnetic memory array, comprises forming a green ferrite sheet with depressions such as grooves in it, applying a slurry of non- magnetic particles, 0À5-5Á in size, in a carbonaceous binder solution, allowing the slurry to dry, brushing off the surplus, laminating with another green ferrite sheet, and firing to leave a ferrite body having an imbedded pattern of compacted non-magnetic particles. The green ferrite sheet may be formed of calcined ZnMgMn ferrite with a binder, and made by spreading the mixture on a plate with a raised pattern, to a thickness of 0À001-0À02 inch and drying. The slurry is formed by dispersing the particles in an aqueous solution of sugar and honey. The particles may be Pd, Pt, Rh, Re or alloys thereof with Au or Ag if the imbedded parts are to be conductive, i.e. conductors or shields, or MgO or SnO if these parts are non-conductive for limiting flux paths. The green ferrite sheets may be laminated together by pressing for 10 minutes at 90-105 C. The laminated sheet is heated to 200-400 C., and then sintered at 1200 C. After cooling in air the structure is annealed in N 2  at 1100 C. During the sintering the sugar binder is driven off, this loss in volume corresponding with the shrinkage of the ferrite. Several green ferrite sheets may be laminated together to form a multilayer structure.

In a small synchronous motor, for clocks &c., the core 18 which carries the energizing coil 19 and which has at its upper end an inner ring of poles 25 of one polarity, is secured at its lower end to a magnetic plate 12 having up-turned sides 13 making connection with a plate 15 which provides the opposite poles. Some of the poles projecting from the disc at the top of the core pass through holes in an aluminium shading plate 35 (Figs. 12, not shown). A ferrite rotorring 42, carried on shaft 40, is magnetized to present a uniform series of poles to the stationary poles. To prevent locking, the inner stator poles, Fig. 10, 29, 30, 31, are unevenly spaced and the outer stator poles (projecting from plate 15) do not occupy all the spaces between them (Figs. 3 and 14, not shown). The rotor, Fig, 16, is surmounted by an output pinion 49 and a snail cam 46 which engages a resilient buffer 67 carried at the top of the next gear-wheel 63 and arranged by friction with this wheel to be rotated into engagement with the snail-cam when the rotation is reverse. The spindle 40 is lubricated by a wick assembly 52.

Title: Improvements relating to textile yarns
Inventor: KIRBY JOHN ALBERT
IPC: D02G1/00
Filed: 1963-11-06
Abstract: A freshly spun or twisted yarn of thermoplastic fibres is rendered "kinky" by forming it into a single stitch chain which is set by passage through a heating zone (at a temperature just below the softening temperature of the fibres) and then through a cooling zone, finally unravelling the chain.  A number of chains may be wound in side-by-side relationship on a beam and, prior or subsequent to winding, set, e.g. by heating and cooling the beam. The chains may then be withdrawn, unravelled and the yarns fed directly to a carpet-making process such as tufting.
