Title: Improvements in or relating to current-limiting arrangements for indirectly heated valves
IPC: H03F1/54
Filed: 1938-11-22
Abstract: 521,714. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., and FILBY, F. G. Nov. 22, 1938, No. 33952. [Class 40 (v)] A relay responsive to the voltage across the filaments of indirectly heated valves is used to cut out a series resistance in the filament circuit and to prepare a circuit for an alarm relay which is operated by relays in the valve plate circuits and which prepares the alarm circuit. The relay FR is arranged to energize when the valve filaments FI-F4 have become sufficiently hot for their resistance to be reduced to their normal hot value. The relay at contact FR1 removes resistance R2 from the filament heating circuit and prepares a locking circuit for relay AR which energizes and locks when relay VIR in the plate circuit of valve VI has energized. Relay AR prepares the circuit for alarm relay AL which relay is energized when any one of the anode circuit relays V1R-V4R releases. An additional contact FR3 in the anode supply lead may be provided to ensure the operation of relay FR before the plate circuit relays so that chattering of the alarm relay is prevented.

Patent GB-344868-A (GB)
IPC: G06C23/02
Abstract: 344,868. Adding-machines. DEHN, F. B., 103, Kingsway, London.-(Felt & Tarrant Manufacturing Co. ; 1717, North Paulina Street, Chicago, U.S.A.) Sept. 9, 1929, No. 27390. [Class 106 (i).] In a key-responsive power-operated adding- machine for example such as is described in Specification 181,043, [Class 106 (i), Calculating &c.], the depression of a key results in the engagement with a constantly driven ratchet element, of a pawl connected with the actuator which is consequently moved to a differential position and then restored by spring action to actuate the counter. For each bank of keys there is a bar 101 supported from centres at 74 and 104 and carrying a pawl 99 normally held up in the position shown, Fig. 2, by a spring-controlled lever 126 pivoted to the bar at 102. Depression of a key, acting through a parallel-motion system, lowers a dog 133 (see Fig. 11) which in turn depresses the lever 126. The pawl is not immediately lowered however but is finally released when a lug 153 on the parallel-motion bar 143 moves sufficiently to the right. The pawl then descends into engagement with the constantly rotating ratchet wheel 98 which consequently draws the bar 101 to the left against the pull of a spring 77 and through a friction clutch at 113 rotates the actuating sector 73. The rotation of this sector is terminated by engagement with the depressed key of a differential bar 173 linked at 178 with the sector. The dog 133 is held down by a latch 148 pivoted on the bar 143 and tripped by a lug 168 on lever 126. To ensure full engagement of the pawl with the ratchet wheel a spring-raised arm 164 is provided and has a lug 167 to lower the pawl by co-operation with a lug 128 on the pawl. The leftward movement of the pawl by the ratchet wheel is terminated automatically by the pawl riding up the teeth and the lug 128 can pass above the lug 167 on the return journey. The accurate setting of the actuating sector is further ensured by the provision on a bar 183 pivoted to the end arms of the parallel-motion system and formed with lugs 184 to enter a hole in the stem of the key depressed and thereby to hold it down until the key is released. Specifications 148,292 and 154,603, [both in Class 106 (i), Calculating &c.], also are referred to. Keyboards.-The keys are mounted in a removable frame comprising parallel spaced plates 47, 48, 49. The return springs 58 of the keys are supported on the middle plate 48 while the lowest plate 49 carries slidable conical-ended bolts 66 adapted to be thrust by depression of a key into locking engagement with the stems of adjacent keys.

Filed: 1966-08-02
Abstract: 1,188,113. Making aromatic hydrocarbons and oil gas. GAS COUNCIL. 2 Nov., 1967 [2 Aug., 1966], No. 34635/66. Heading C5E. Hydrocarbon oils, preferably a light distillate, are hydrogenated to produce aromatic hydrocarbons in two successive zones of a fluidized bed, e.g. of coke, which is continuously circulated up at least one riser and down at least one down-comer, hydrogen being separately supplied to both zones. The apparatus is similar to the one described in Specification 1,154,321, but is provided with nozzles, or an apertured annular ring, at an intermediate internal point in the riser or risers for delivery of hydrogen to the second zone. The first zone is thus the lower portion of the riser, the proportions of reactants and the temperature being selected so that aromatic hydrocarbons are synthetized there, and the portion of the riser above the intermediate point constitutes the second zone where unsaturated hydrocarbons and hydrogenated and benzene homologues dealkylated. Temperature control is by adjustment of the degree of preheating of the reactants. The oil feed may be evaporated in the stream of hydrogenating gas externally of the reactor, or may be delivered as liquid or vapour into the base of the fluidized bed, see Figure (not shown). Fluidization may be achieved by the reactants, or nitrogen, steam or methane may be supplied, separately or mixed with the hydrogen. Air may be supplied to the first zone. A portion of the aromatic product may be separated and recycled to the first or second zone for further hydrogenation. Feedstocks include kerosene, gas oil and crude oil, and in an example a gas consisting mainly of H 2 , CH 4  and C 2 H 6  was produced, together with aromatic hydrocarbons, mainly benzene.
