Title: Ferro-magnetic cores
Inventor: PADDISON ERIC
IPC: H01F41/02
Filed: 1964-07-03
Abstract: 1,088,411. Electromagnets. ENGLISH ELECTRIC CO. Ltd. July 1, 1965 [July 3, 1964], No. 27512/64. Heading H1P. In a laminated ferro-magnetic core 11, such as an electromagnet, holes provided in first and second laminations are arranged to overlap one another so that an adjusting tool may be inserted through these holes at 15 or 16 to effect relative movement of the first and second laminations on rotation of the tool. As shown, slots 18 enable the upper set of laminations 13 to move relative to the fixed lower set of laminations secured at 17 so as to vary air gap 19 as the tool is rotated. Alternatively both sets of laminations may be movable. The laminations may be F-shaped (Figs. 3 and 4, not shown), and the holes may be slot, circular, or triangular shaped. The slots (20) of the upper laminations (Fig. 3) are arranged to overlap the circular holes (21) of the lower laminations so that on inserting a tool (such as in Fig. 2, not shown), a cam surface (25) on the tool moves the slots (20) within the holes (21) to effect relative movement of the laminations. Also a combination T- and E-shaped laminations (Fig. 5, not shown), may be used.

Title: Improvements in or relating to the production of beryllium metal
Inventor: CROOK ROBERT DEREK
IPC: C25C3/34
Filed: 1959-08-12
Abstract: 900,698. Producing beryllium by electrolysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 22, 1960 [Aug. 12, 1959], No. 27637/59. Class 41. Beryllium metal is produced by the electrolysis of a binary anhydrous beryllium chloride/ sodium chloride melt characterized by the step whereby the melt, depleted in BeCl 2  content after electrolysis, is passed down a packed column (e.g. of nickel Lessing rings) in countercurrent flow with BeCl 2  vapour passing up the column so as to enrich the melt with the vapour by direct contact, prior to it being returned to the electrolysis stage. The above step is carried out in the direct contact condenser 6 illustrated in the process diagram of Fig. 1 which uses wet beryllium hydroxide as the starting material. The dried hydroxide is first calcined at 500‹ C. in a fluidized bed using air heated to 800‹ C. as the fluidizing medium, to drive off free and combined water leaving beryllium oxide, which is then mixed with carbon from a hopper 2 and with recycled carbon/BeO debris from pelletising machine 4 in a mixer 3, the C: BeO ratio being adjusted to 1:1. The mixture is formed into pellets by the machine 4 to be charged into a chlorinator 5 in which chlorine gas is passed through a bed of the pellets heated to 800‹ C. to form BeCl 2  vapour and carbon monoxide. The gases from the chlorinator, including excess chlorine, pass (at 500‹ C.) upwards through the condenser 6, down which the BeCl 2 /NaCl melt (depleted in BeCl 2 ) is recirculated at 300‹ C. from a pump tank 7. The melt, enriched by absorbing BeCl 2 , flows out to the tank 7 where it is passed to a purifying electrolytic cell 8 to remove nickel and iron impurities, prior to being pumped to a main electrolytic cell 9 from which depleted melt flows back to tank 7. Beryllium metal is deposited in flake form in the cell 9 on a pure nickel cathode using a carbon anode.

Title: Apparatus for coiling strip material
IPC: B21C47/06
Filed: 1957-09-04
Abstract: 875,372. Winding and reeling. UNITED ENGINEERING & FOUNDRY CO. Sept. 4, 1957 [Sept. 4, 1956], No. 27989/57. Class 83 (4). Strip coiling apparatus includes a rotatable reel on which strip is to be coiled, at least one strip guiding roll arranged adjacent the reel periphery and displaceable away therefrom, means for withdrawing said roll from its strip coiling position and connected to means carrying said roll, and resilient means interposed between said roll and its carrying means, whereby at the instant the point of overlap is engaged by said roll the roll will be displaced momentarily away from the reel and relative to said roll carrying means and thereafter during completion of said each successive wrap the roll will assume its initial position with respect to its carrying means. Strip from a rolling mill is directed by rolls 21, 22 and an inclined guide 16 to a rotated reel 15. Wrapper frames 23 pivoted at 24 to machine side frames 12 are located at diametrically opposite sides of the reel 15 and carry a driven wrapper roll 25 and a curved strip guide 26. The frames 23 are swung into their operative position by constant pressure piston and cylinder means 28 an adjustable stop 33 on rod 31 on each frame limiting its movement towards the reel 15. A bottom section 18 of the lower end of the guide 16 is fixed to the left-hand frame 23 and a top section 19 of the guide 16 is pivotable about a shaft 36 and is linked at 37 to the right-hand frame 23. At the bottom of the coiler a crimping roll 39 on a pivoted arm 41 is moved by piston and cylinder means 43 to press the last wrap of the strip firmly against the reel. Each roll 25 is mounted at its ends in brackets 44, pivoted at 45 to the frame 23, and each connected at 48 to a clevis 47 on a shaft 51. A spring 52 around the shaft 51 presses on the clevis 47 and on a nut 55 screwed in a chuck 56 secured to the frame 23. A washer 62 and nut 63 on the shaft 51 abut the outer end of the nut 55. To increase the spring pressure the nut 55 is rotated to compress the spring 52 and the nut 63 is then tightened up. A projection 65 on the bracket 44 engages a stop 66 on the frame 23. Each roll 25 is pushed away from the reel by the point of overlap of strip thereon to compress its spring 52 and during the completion of a wrap and before the overlap again passes under that roll, the spring 52 overcomes the constant pressure of the means 28 so that the frame 23 gradually moves away from the reel until the roll 25 is in its original position relative to the frame 23. In a modification, Fig. 5, two rolls 72, 73 are slidable against springs 76 in a frame 74 retracted by piston and cylinder means 78 through bell crank means.

Abstract: 535,785. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., and MADDOCK, A. J. Oct. 20, 1939, No. 28334. [Class 40 (v)] A valve V or chain of valves supplying a conductor T, e.g. an aerial, is prevented from supplying energy to an arc or flash-over, e.g. at a gap G, by causing the arc to complete the circuit of a negative bias B2 to a control electrode of the valve. As soon as the arc ceases, the negative bias is disconnected. A filter L1, L2, C prevents oscillatory energy in the conductor T being fed back to the valve. The arrangement may be adapted to several aerials fed from the same valve chain, and also to a single aerial fed from parallel valve chains.

Abstract: 425,629. Valve circuits for wireless reception. MULLARD RADIO VALVE CO., Ltd., and CLARK, R. G., Nightingale Lane, Balham, London. Oct. 14, 1933, No. 28464. [Class 40 (v)] In a wireless receiver employing valves with directly heated cathodes, a double diode valve is employed for signal rectification and automatic gain control, the signal anode being associated with a part of the cathode positive with respect to the part associated with the other anode. The signal input anode 6 of the double-diode-triode 7 is connected through load resistance 13 to the positive side of the cathode circuit but co-operates with the negative side. Conversely, the gain control anode 10 is connected through load resistance 15 to the negative side of the cathode but co-operates with the positive side. Thus a delay voltage of nearly 4 volts is obtained in respect of the gain control voltages.
