Title: Improvements in or relating to glass feeding machines
IPC: C03B7/10
Filed: 1922-10-25
Abstract: 195,927. British Hartford-Fairmont Syndicate, Ltd., (Assignees of Hiller, E. 0.). April 6, 1922, [Convention date]. Delivering m o l t e n metal. - An automatic feeder having a number of elements which cooperate to deliver the charges of molten glass has means for independently rendering one of the elements inoperative, and means for returning the element to operation in proper relation to the operation of the other elements. The invention is shown in Fig. 1 applied to a paddle feeder, and consists of a device for stopping the operation of the shear blades 8 and for starting them again in proper relation to the strokes of the paddle 23. The blades 8 are reciprocated horizontally by levers 9 pivoted at 10 and operated by springs 34 and by cams 12 on a shaft 13. A handle 25 is connected by segmental gears with a shaft 29 which raises or lowers slides 33, the upper ends of these slides being connected to arms 34 pivoted on the studs 10. By turning the handle, the slides can be raised to lift the arms 16 of the shear levers 9 and thus hold the shears in the inoperative position. A latch 38 engages a lug 37 and prevents the return of the handle 25. The latch is connected bv a rod 53 with a bell crank 47 on which is pivoted the yoke 45 of a roll 44. A spring 48, Fig. 2, normally holds the roll 44 out of the path of a cam 43 fixed on one of the shear cams 12. When it is desired to start the shears, a handle 50 is turned to bring the roll 44 into the path of the cam 43. The cam thus raises the latch 38 and allows the shears to come into operation at a particular point in the rotation of the shaft 13 and, therefore, in proper relation to the rest of the mechanism.

Abstract: 865,620. Valve multistable switching circuits. ERICSSON TELEPHONES Ltd. Aug. 25, 1959 [Sept. 11, 1958], No. 29172/58. Class 40(6) [Also in Group XIX] A circuit for stepping a glow discharge in a multi-cathode discharge tube D sequentially from cathode to cathode comprises a sequence of trigger electrode gas filled discharge tubes T1. . . T10 whose anodes are connected to the cathodes respectively of the multi-cathode tube. The trigger tubes have individual anode and cathode load resistors, and each adjacent pair have their anodes connected together through a capacitor C1 . . . C10, their cathodes connected through a capacitor C31 . . . C40 and the cathode of the first tube of a pair connected through a resistor R11 ... R20 to the trigger of the second. The trigger electrodes are connected through individual capacitors C11 . . . C20 to an input terminal which is connected to a pulse generator P. The tube D is preferably of the type in which the cathodes are formed in the shape of numerals or other symbols and momentarily closing the switch S causes tube T10 to strike, producing a glow at cathode K0, which is shaped like a O. The rise in potential of the cathode of T10 is fed to the trigger of tube Tl to prime it, so that a first pulse from generator P causes Tl to conduct and initiate a glow at the cathode K1. At the same time the drop in potential at the anode T1 and the rise of the cathode, are transmitted through cathodes C10, C40 to extinguish tube T10, and tube T2 is primed so that the next pulse causes this tube to strike and extinguish tube Tl. The sequence is continued until after tube T9 striking, tube T10 and further tube T11 are primed, so that upon T1 0 striking T11 also strikes to provide a triggering pulse for a further decade unit. Tube T11 is self extinguishing due to capacitor C42. Diodes X1, X2 are provided in the trigger electrode circuits of tubes T10, T11 to prevent discharges between the triggers and anodes.

Title: Improvements in or relating to multifrequency signal receivers
IPC: H04Q1/453
Filed: 1961-08-18
Abstract: 915,793. Voice-frequency signalling. WESTERN ELECTRIC CO. Inc. Aug. 18, 1961 [Aug. 22, 1960], No. 29880/61. Class 40 (4). In a system which employs as signals a combination of two frequencies selected from different frequency bands A, B, the receiving equipment is guarded against operation by spurious signals, e.g. speech or noise, by a circuit which checks that the two frequencies are coincident in time over a predetermined period. As shown, the input signals are fed through band-elimination filters 4, 5 and limiters 3, 6 which deliver a square-wave output to tuned circuits 7 ... 14 and detectors 31-38, the latter being biased to be non-conducting unless the input level is above a certain threshold value. The duration test circuit 59 is fed from the output of the detectors through OR gates 39, 40 and AND gate 58 and initiates operation of a timer 60 provided the two frequencies persist for 30 ms. for example. The timer generates a pulse of 50 ms. duration to enable AND gates 41 ... 48 and allow operation of the appropriate output amplifiers 49 ... 56, feedback being provided through OR gates 23...30 to ensure operation for the full duration of the pulse. To prevent irregular operation in the event of a brief valid signal being followed by spurious signals, the timer 60 also exercises an inhibiting effect through an amplifier 57 on AND NOT gates 15 ... 22 in the output of the tuned circuits 7 ... 14, the operative detectors then being maintained by means of feedback alone. The receiver employs transistor circuits which are described with reference to Figs. 2, 3 (not shown).
