Title: Industrial process controller
IPC: G05D7/06
Filed: 1962-04-16
Abstract: 959,718. Valves. FOXBORO CO. April 16, 1962 [April 26, 1961], No. 14563/62. Heading F2V. [Also in Divisions G3 and H2] In an electrical system for automatically maintaining a desired rate of flow in a pipe (see Division G3) one or other of two electromagnets is energized according to the sense of any deviation to cause a strip 142, 144, Fig. 12, to engage a pawl 132 or 134 with a nut 122. Nut 122 is thus rotated step by step in a corresponding sense by an eccentric drive 116 from the shaft 115 of a continuously rotating electric motor (not shown). Nut 122 is internally threaded on to a member 123, Fig. 13, which thus raises or lowers a valve stem 114 as necessary to correct the flow in the pipe (not shown). An arm 170 moving with member 123 operates switches 174, 180 to de-energize one of the electromagnets at each limit of travel of the valve. If, during closing, the valve stem meets an obstruction, a spring 162 is compressed to rotate arm 170 in an anticlockwise sense to open switch 174 and de-energize the control circuit. Specifications 724,632 and 871,669 are referred to.

Rotary sieves.-In sifting apparatus for treating potters slip and the like, two lawn frame cages g are slidingly mounted in rotatable carriers b, the hollow trunnions of which are journaled in a casing a. The lawns of the lower cage are finer than those of the upper cage. One side of the casing is provided with doors positioned by means of turn-buttons 6. Each cage g is positioned in its carrier b by means of a hollow clamping screw q which passes through one of the trunnions j, and bears against a plate r so that a rubber ring s, between the other end of the cage and the carrier, makes a tight joint round a supplvpipe t which is contained in and rotates with the other trunnion j. A feed-pipe t' is internally screwed to receive a nipple v, the other end of which is screwed into a sleeve u freely mounted in the trunnion j. The skeleton cage g, Fig. 7, is open on all sides, but closed at the ends, each side being recessed at 8 to receive a lawn frame 9<a>, Fig. 12. The inside of each recess is lined with rubber, felt, or the like, and a perforated zinc or other metal plate 11 may be employed between the frame 9<a> and the lawn 9. A thin metal clamping-frame provided with handles secures each @a @n frame 9<a> in position, a peripheral flange thereon taking into a groove 15 in the side of the cage g The clamping frame is positioned by means of bolts 16 and wing-nuts. To control the force of slip entering the cage a fence plate 18, Fig. 7, is secured to the inlet end thereof. A pipe w with a flared end w<2> secured to. the other end of the cage communicates with the hollow trunnion j, Fig. 2. The cages are actuated from a shaft p through the belts n<1>, n<2>. Slip, pumped in through the pipes t<1>, t is sifted in the upper lawns, and then passes through a pipe x to the lower lawns, through which it passes to the outlet pipe h. When knottings accumulate in the lawns, some of the slip passes out through the pipe w and the scre.w q, indicating that the lawns require cleaning.

W. ; Port Jefferson, Long Island, New York, U.S.A.) May 15, 1934, No. 14670. Convention date, May 24, 1933. [Class 40 (v)] The grid voltage of a carrier wave amplifier or generator O is varied by varying the direct current through a resistance R in its grid circuit, the key K or microphone M being arranged to vary the resistance of triode valves V3, V4 connected in series with said grid resistance R and with a supply rectifier. As shown, the rectifier is of the full-wave type comprising two diodes V1, V2 supplied from the mains by transformers T1, TF1, TF2' the D.C. output being smoothed by a choke X and a condenser C. The rectified current flows from the mid-point of supply secondary T1, through choke X, resistance R, earth, valves V3, V4 in parallel, to the rectifier filaments. During marks, the key K is down, the grids of valves V3, V4 are negatively biased by the source B and the direct current flow is cut off. The high-frequency valves O then oscillate or amplify in normal manner. When the key K is open, the valves V3, V4 conduct and current flowing through the resistance R biasses the grids of the valves O so that they are inoperative. By suitable adjustment of the source B, the microphone M can be arranged to modulate the output, the key K being closed. Tone telegraphy can be effected by substituting a tone generator for the microphone.
