Title: Improvements in or relating to electric generators for the regulation of electric arc furnaces
IPC: H05B7/00
Filed: 1927-03-24
Abstract: 292,272. Soc. d'Etudes et de Constructions Metallurgiques, and Grenet, J. L. M. G. March 24, 1927. Exciting.-In a generator for regulating electric arc furnaces and having both continuous and alternating-current fields, the two sets of field coils are so arranged as to avoid mutual induction, one of the alternating fields being optionally derived from a current transformer or by compounding two currents of different phases. The form shown is designed to give the relationship f (UI)=a U-bI-c, where U is the p.d. between the arm electrode and the bed, I the electrode current and a, b and c constants, the regulation being effected by a motor which regulates the electrode position and has a speed proportional tu the quantity f (UI). This is brought about by employing a continuous-current motor with constant separate excitation and an armature fed with a voltage proportionate to f (UI) given by a generator of the type described. The generator field structure is wound as in Fig. 2 with five coils, numbered similarly to those shown in Fig. 3, viz. a bi-polar continuous-current winding 1 producing the poles n<1>, s<1>, s<2>, n<2>; an alternating- current winding 2 energized by the arc volts and wound on two of the poles; a second alternating- current winding 3 energized through a current transformer Ti and acting on the other two poles: and two other continuous-current windings 5 and 6 respectively producing a voltage proportional to the constant c and giving a compounding effect. In addition, shod-circuited windings 4 are provided to localize the effects of the windings 1, 2. The generator G<1> is driven by a motor M, which also drives the shunt-wound generator S giving the constant voltage from which the fields of the electrode motor M<1> are excited. A rheostat Rh enables the ratio of the electrode current to that in the coil 3 to be varied. A separate generator may be employed for each phase of a polyphase are or the separate machines may be compacted into one by employing a multipolar machine. Also, in place of connecting the generator to the constant-excitation motor M<1>, it may excite the fields of another motor-driven generator which, in turn, excites the motor M<1> in the manner of a Ward Leonard system.

Title: Electrically actuated rotary valve zone heating control system
IPC: F16K31/04
Filed: 1958-10-09
Abstract: 886,632. Automatic temperature control systems. DOANE, D. B. Oct. 9, 1958, No. 8355/59. Divided out of 886,631. Class 38 (4). [Also in Groups XXIX and XXXVII] A plurality of motor-actuated rotary valves 11, Fig. 1, each carrying a switching device and each controlled by a temperature-sensitive device, e.g. a thermostatic switch 93, Fig. 8, have an electric power source at 90 common to all the temperature-sensing devices, switching devices and valves and an electrically-operated heat-transfer medium flow producing device, e.g. the electric motor pump 107 passing heat transfer medium through the valves, which is electrically connected to the switching devices and electrical circuitry so arranged that any one of the switching devices brings the flowproducing device into operation. The rotary valve comprises a valve 11 controlling flow through the body 10, a base-plate 25 removably attached to the body and carrying a unidirectional electric motor 64 mounted on a terminal plate 43 and a rotary switch 55, and a motor shaft extending through the terminal plate and through and connected to the rotary switch into driving engagement with the stem 33 of the valve for unidirectional co-rotation of the switch and the valve. On heat demand thermostatic switch 93 connects with contact 92 and current flows from a transformer secondary coil at 90 via a conductor 80 continuously in contact with the rotor 72 of the switch, and via rotor arm 87 connecting contact 79 through the motor 89 which then begins to open the valve and turn rotor 72. When the valve is partially open rotor arm 87 engages contact 81 whereby current flows through a relay for operating a pump circulating heating medium through the valve. When the valve is fully open arm 87 leaves contact 79 and engages contact 82 and motor 89 stops. When the heat demand is satisfied switch 93 returns to contact 94 whereby current flows via contact 80, rotor 72, arm 87 engaging contact 82 so that motor 89 continues rotating in the same direction until arm 87 leaves contact 81 to stop the circulating pump and when the valve is closed arm 87 leaves contact 82 and diametrically opposite rotor arm 88 engages contact 79 preparatory to operating the valve on a further heat demand. The base-plate 25, Fig. 3, has brackets 30, 31 engaging ears 22, 23 on the valve body to hold the plate in position and carries a plate 35 located on the base-plate by a bridge 34 which engages a notch 32 in the valve stem to retain the valve in the body. The terminal plate is secured to the base-plate by spacers 41, 42 and the switch s carried beneath the terminal plate by spacers 53, 54. A circuit is shown and described in which three valves are controlled from the same power source and in which the three switches control a single circulating pump relay. In a further arrangement the circulating pump motor is driven directly from the mains through the switch and contact 81 without the use of a relay.

Abstract: 699,975. Type-bar-making machines. MERGENTHALER LINOTYPE CO. April 16, 1951 [April 15, 1950], No. 8804/51. Class 100(iii) Magazines. A typographical composing machine, such as is known under the Registered Trade Mark " Linotype ", having a base frame removably supporting a matrix magazine, and a magazine lifting and supporting plate pivoted to the base frame and adapted to be swung upwardly to locate the magazine in position for removal or replacement, is provided with a releasable locking device for maintaining the magazine in place on the lifting plate. The machine, including the base plate, lifting plate and lifting mechanism, is substantially of the construction disclosed in Specification 508,612. Slidably secured to a guide piece E5 secured to the front of the lifting plate E, Fig. 3, is a locking plate L, having a notch aligned with notch E7 in the plate E to receive the long centre bar a of the magazine. The plate L is urged to the left by a spring L5 into a position wherein a lug L4 overlies the bar a and prevents the raising of the magazine off the plate E. When the plate E is raised by the cam F, the lug F2 of which engages the pin F3 on the plate, a second lug F4 of the cam engages a cam surface L7 on the plate L and slides the plate into release position as the plate E reaches its uppermost position. On lowering the plate E after magazine replacement, the plate L is immediately released and moves into locking position. In another form, Fig. 7, the locking plate M engages a recess a2 in the bar a, and has a depending lug M2 with an inclined slot M3 engaged by a pin M4 on an actuating slide M5 normally urged to the right by a spring M8 to hold the plate M in locking position. The pin F3 is secured to the slide M5 instead of to the plate E, and when the lug F2 engages the pin, the slide M5 is retracted and moves the plate M into release position. If a replaced magazine is not correctly positioned on the plate E, the plate M cannot return to locking position, and a plate N secured to the lug F2 abuts the lug M2 so that the cam F cannot be moved to lower the plate E. In both forms, the mechanism described is provided on each of the magazine lifting plates in a multi-magazine assembly, but the cam shaft Fl, Fig. 3, is only operatively connected to the actuating magazine supporting arm when its magazine is in operative position with respect to the assembling mechanism. The locking device is also applicable to a single magazine machine. Specification 260,459, [Class 100(iii)], also is referred to.
