Abstract: 924,207. Mounting furnace electrodes. SAMUEL FOX & CO. Ltd., and A.E.I.- BIRLEC Ltd. April 29, 1959 [Jan. 29, 1958], No. 2903/58. Class 39 (3). An electrode clamp of an electric arc furnace comprises a shoe 1, Fig. 1, with a channelshaped holder 2, the shoe seating on the base of the holder, the arms of a rigid U-shaped strap 3 embrace and slide upon the external surfaces of the walls of the holder 2 so as to bridge the mouth of the holder so that when an electrode 14 extends through the holder it is gripped between the shoe and the strap by moving the strap towards the base and the electrode is released by moving the strap in the opposite direction. The shoe serves as a current lead. The sliding movement is obtained by a forked lever 11, the two arms of which are pivoted by a common pivot pin and which pass through transverse slots 10 in the free ends of the strap 3. The remote end of lever 11 may be actuated by the piston-rod of an hydraulic cylinder (not shown). The shoe is arcuate and has transverse ribs and the strap has a semicircular bridge and flanges 25, a strengthening rib 26 and slides between lugs 7 on side cheeks 5 of the U-shaped holder 2, blocks 27 on the strap 3 and holder 2 and on a heat shield 29 are bridged by wires 28 so that the heat shield shields the electrode holder from the furnace. A horizontal rod can be raised and lowered with respect to the furnace so as to raise and lower electrode 14. The shoe 1 has a recess seating on the holder base and a lip at its upper end bolted to plates on two bus tubes which act as current leads and coolant ducts and which communicate with a sinuous cooling duct in the shoe and with the cross-head 15 by pipes to provide a cooling circuit. The shoe 1 is a copper casting and holder 2 and strap 3 are of ferrous metal.

Title: Improvements in and relating to the control of water turbines and the like
IPC: F03B15/20
Filed: 1921-01-26
Abstract: 180,386. Gilkes & Co., Ltd., G., and Thorpe, G. E. T. Jan. 26, 1921. Regulating.-In control gear for hydraulic turbines comprising a deflector 7 and a nozzle spear valve 5, the pressure fluid from the nozzle inlet has direct access to one side of a piston 14 on the spear valve rod 4, and on the other side the inflow is adjusted by a valve 26 and the outflow regulated by a poppet valve 16 bearing on an outlet port in the piston through which this pressure fluid passes along the hollow valve rod 4 into the jet. According to the invention, a dash pot 24 connected to a bell-crank lever 20 with an adjustable tappet 21 bearing on the poppet valve 16 prevents this valve following up the piston too quickly, but allows its quick return: In operation, on a rise of speed occurring, the deflector 7 connected to a governor sleeve 12 immediately masks part of the jet and the linkwork 11, 37, 36, 35 compresses a spring 34 bearing on a lever 33 of the bell-crank lever 20 so that the poppet valve 16 moves forward but only slowly by reason of the dash-pot 24; the outlet behind the piston 14 being therefore closed, the pressure increases and the spear valve 5 moves slowly forward to close the jet and at the same time the deflector 7 moves out of the jet. On a fall of speed, the link-work 'positively rotates the bell-crank lever 20 and the pressure returns the poppet valve 16. A filter 27 is provided for the pressure fluid before it reaches the valve 26.

Title: Improvements in shot exploders
Inventor: WARNE MICHAEL ANTHONY
IPC: F42D1/05
Filed: 1960-01-29
Abstract: 910,045. Testing for continuity. MARSTON EXCELSIOR Ltd. Jan. 9, 1961 [Jan. 29, 1960], No. 3250/60. Class 37. A shot exploder has a testing circuit and an external circuit including a number of detonators, the testing circuit including two transistors connected such that when the external circuit resistance is below a predetermined value the emitter to collector conduction of the first transistor is altered causing the second transistor which has its base connected to the collector of the first transistor, to be energized and indicating means connected to the collector of the second transistor to operate. The indicating means may be a lamp which lights to indicate that the circuit is safe for exploding, that is when the total resistance is sufficiently low as to indicate that all of the detonators are connected satisfactorily. The first transistor is preferably of silicon type to reduce the sensitivity of the circuit to temperature changes. As shown in Fig. 1, electric detonators are connected across terminals 1, 2 and a sufficiently low value of firing circuit resistance will cause transistor 10 to be cut-off so that the resulting base current flow through resistor 11 to transistor 12 causes the latter to conduct and the lamp 13 to light. The circuit of Fig. 7 includes three transistors 10, 36, 12 connected so that a sufficiently low value of firing circuit resistance results in transistor 10 being biased off, in transistor 36 conducting and in transistor 12 being biased off so that this latter transistor does not act as a low resistance shunt across the indicating lamp which will consequently be illuminated. In the circuit of Fig. 2 (not shown), the bias to the emitter is obtained from a potential divider and a resistor is connected in parallel with the external circuit. In the circuit of Fig. 4 (not shown), regeneration is provided from the collector of the second transistor to the base electrode of the first. The two transistors may also be of opposite conductivity types, Figs. 5, 6 (not shown).
