Abstract: 766,080. Energy meters. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 19, 1954 [Nov. 27, 1953], No. 33561/54. Class 37. In a watt-hour meter comprising two current windings 31, 33 connected in parallel and thus forming a closed loop 59, a magnetic member 63 is provided which presents a high impedance to circulating currents induced in the loop 59 by the current in the voltage coil 29 but a low impedance to the load current flowing in parallel through the two windings 31, 33. The magnetic member 63 comprises a loop of magnetic material twisted into a figure of eight configuration and surrounding the two arms of the loop 59 as shown, it will thus be seen that the portions of the load current flowing through the two current coils will set up oppositely directed magneto-motive forces in the loop 63 while circulating currents will produce a resultant magneto-motive force in the loop which consequently presents a high impedance to such currents. Fig. 4, not shown, illustrates the application of the invention to a three-phase system comprising two separate watt-hour meters as shown in Fig. 1.

Abstract: 857,536. Drilling-machines. BROWN & SHARPE MFG. CO. Oct. 5, 1959 [Nov. 20, 1958], No. 33672/59. Class 83 (3). A drilling &c. machine comprises a tool-holder 38 aligned with a spindle 12 rotatable in a quill 10, along which a support 29 for the holder is axially movable, mating tapered surfaces 20 on the holder and spindle for connecting them, and fluid-operated means for engaging the surfaces, the latter means having a piston 25 and a cylinder, one of which is connected to the quill and the other to the tool-holder support. In a turret-drilling machine, a quill 10 supports the spindle 12 to which a driving member 16 is attached by a nut 18, a taperedsocket 17 and a pin 19. Each tool-holder 38 has a spherically-seated bearing 40a, and has a tapered shank 38a slotted to receive spring- pressed driving plungers 22 on the spindle 12. When the quill 10 is moved downwardly, a spring 42 forces the turret 29 upwardly until the tool-holder is connected to the spindle. The force of the spring 42 is supplemented by compressed-air entering a space between the piston 25 on the quill and the turret. The air supply is cut off when the turret is raised, by actuation of a valve 48a. The turret may be rotated by a hand wheel 49. The supplementing of the force of the spring 42 by the compressed-air reduces the force which the operator has to apply to the quill at the commencement of the feeding movement. In a modification, a double-acting piston 54, Fig. 3, is controlled manually to move the turret to cause tool rotation. The turret-carrying member 53, or the work, is then moved axially to effect feed. In further modifications, liquid is used instead of air, and the piston of Fig. 1 is replaced by a double-acting piston, and 'the spring replaced by air, which is compressed. Specification 764,671 is referred to.

To actuate piston 11, switch 17a is thrown to connect the pump 13 to line 20, say, and line 19 to exhaust. Since the springs 33 are weaker than the springs 37, the piston 26 (on the left) is pushed back first to admit liquid via ports 34, 35 to the lower side of the piston 11. Piston 23a (on the left) is then pushed back, pulling with it the upper plunger 23. The pressure above piston 11 then pushes the right-hand valve 31 to the left, so that liquid can flow via ports 35, 34 and line 19 to exhaust. A neutral position of switch 17a will lock the motor, but if excessive pressure occurs valve 31, plunger 23 and piston 23a can be pushed back to allow liquid to escape.
