Abstract: 660,322. Making transformer &c. cores. TELSA, NATIONAL CORPORATION, and TRESOHLAVY, V. May 4, 1949 [June 26, 1948], No. 11911/49. Class 83 (ii). [Also in Group II] A machine for assembling transformer core laminations into coils comprises an elastic, coil-carrying support 1, which is urged against an abutment 10 which determines the level of the topmost inserted lamination so that a further lamination pushed into the coil slides over the lamination which has been inserted into the coil 2 by the preceding operation. E and I-shaped laminations are carried in magazines 3, 4 or 31, 41 on each side of the support 1 and a crank-operated pusher 6 or 6<SP>1</SP> pushes with its front edge an E-shaped lamination out of the appropriate magazine. When the front edge of the pusher reaches the space between the magazines 3 and 4 or 3<SP>1</SP> and 4<SP>1</SP>, the upper edge 5<SP>11</SP> of the driving member 5 or 5<SP>1</SP> rises up due to the cam surface 7 or 7<SP>1</SP> and catches the lowest I-shaped lamination from the magazine 4 or 41 so that both laminations, E and I-shaped, are carried along simultaneously and placed within and about the core. The pushing of a lamination under the abutment 10 depresses the spring support 1 in readiness for the insertion of laminations from the other side until eventually the machine is stopped by the breaking of switch 14 by the adjustable bar 12, and the operation of switch 15 by a stop on the crank gear. The magazines 3, 31 have bent portions and stops 16, 161 which restrict the supply of laminations to the lower part of the magazines until the level therein has dropped below a predetermined value.

Title: Improvements relating to voltage stabilising systems
Inventor: HAINE MICHAEL EDWARD
IPC: G05F1/52
Filed: 1951-05-30
Abstract: 700,208. Automatic voltage control systems. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. March 31, 1952 [May 30, 1951], No. 12738/51. Class 38 (4), In order to stabilize the voltage between the cathode :and the accelerating anode of an electron gun assembly of the type including an electron condenser lens with an apertured disc, the electrodes are supplied via a high resistance and the total beam current is automatically varied in response to the voltage, so that the voltage drop across the resistor compensates for variations in the output voltage. The gun assembly may be specifically for voltage control purposes, or may be the gun of an electron microscope. The cathode 2 is connected to the negative side of the supply 10 via a resistor 9, whilst the anode 4 is connected to the (earthed) positive side of the supply by the anode-cathode path of a valve 11. The control electrode 3 is assumed to be suitably biased with respect to the cathode 2. A part of the electron beam passes through the apertured lens 7 to a "spectrometer" 12 from which a voltage proportional to the velocity of the beam is obtained as disclosed in Specification 675,676. This voltage controls the conductivity of valve 11 thereby controlling the voltage at the anode 4 which controls the total beam current which controls the voltage drop across resistor 9 which controls the voltage applied to the electrodes. It is shown that although the total beam current varies with variations in anode (and/or control electrode) voltage, the current in that part of the beam which passes through the aperture of the lens is substantially independent of such variations. The stabilized voltage may be applied to the electron gun of an electron microscope, or alternatively, since the microscope itself has a gun of the type discussed above, the output of valve 11 may be applied to the gun of the microscope, which itself effects the voltage stabilization. In a modification, Fig. 4 (not shown), the negative supply line is earthed, and connected to the cathode via the resistor. The anode is connected directly to the positive line. The bias on the control electrode is then adjusted by unspecified means in accordance with the anode-cathode voltage (measured in an unspecified manner). The resulting variations in total beam current cause the corrective voltage change across the resistor.
