Abstract: 416,554. Securing rolls on shafts. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Warwickshire, and KELSEYHAYES WHEEL CO., Ltd., Dagenham Dock, Essex. Feb. 8, 1934, No. 4144. [Classes 80 (ii) and 80 (iv).] An overhung roll 12 is driven from the main shaft 1 through soft steel pins 15 but is carried on a secondary stub shaft 11, the shaft 1 being supported at its outer end by a bearing. The roll 12 is held on the shaft 11 by a core 20 secured by stud bolt 21, thrust screws 23 being used for separating the cone and roll from its shaft 11. The shaft 11 is secured to the main shaft 1 by gib and cotter 5, Fig. 3, while separation of these can be effected by replacing the ordinary gibs by withdrawing gibs 32 and hammering the cotter in. The shaft 11 is provided with flanged segments 18 received in recesses 19 in the shaft 1 so that if the pins 15 shear, the torsional stress will not come on the cotter 5. In Fig. 4 the roll 12 is secured in its shaft by segment 25 dropped in a groove 26 in the roll shaft. The segment can be removed by radial pin 29 which pushes them out when a central screw 30 with tapered ends is screwed in to push all the pins radially outward. A ring 27 secured by screws 28 closes the recess in the roll. A wire ring 31 facilitates assembly of the segments 25. In Fig. 6 the segments 25 of Fig. 4 are replaced by two taper face segments 34 between which are thrust other taper segments 35 by means of radial pins 29 moved by a central taper ended screw as 30. In Fig. 7 the segments 36 are thrust in between the locking segment 34 by the tapered face 37 of the ring 27, Fig. 4, as it is screwed in.

Title: Improvements in and relating to processes for the production of hydrogen by decomposition under pressure of coke oven gas
IPC: F41G1/393
Filed: 1930-02-08
Abstract: In the production of hydrogen by separation under pressure from coke-oven gas which is first washed with water under pressure to remove water-soluble constituents, an increased yield of hydrogen is obtained by adding the first gaseous fraction evolved on releasing pressure from the wash-water to fresh coke-oven gas prior to washing. The hydrogen may be separated, for example, by liquefying the washed gas at -180 DEG  C. and 25 atmospheres pressure and fractionally vaporizing.  Specification 311,299, [Class 90, Non-metallic elements], is referred to.

Driving, suspending, and balancing.-In centrifugal machine driving arrangements of the kind described in the parent Specification, lubrication is effected by oil flowing from a reservoir p through a pipe o to the spring bearing h on the shaft. When the machine is stationary the oil flows down the spindle f to the ball-end i and the bearings u, e at the bottom of the apparatus. When the machine is running, the oil is thrown out by centrifugal force and after leaving the bearing h passes through the bearing d and a passage t in the casing to the bearings u, e.

Pellets of KCl having a maximum dimension of from 3/16 to ¥ inch are introduced into the melting zone of a vacuum A.C. arc furnace to stabilize the arc while melting consumable metal electrodes of a diameter greater than 1 inch under pressure of less than 1 mm. Hg and at a linear melting rate of less than 20 inches of individual electrode length per minute. The electrodes may be non-circular e.g. three sectorshaped electrodes connected to a three-phase supply. Electrode " diameter " in these cases is the diameter of a circle of equal area. The pellets may be introduced continuously or intermittently during the melting operation and may also be used in the following method of starting the furnace. A striker plate of the same metal as the electrodes is provided at the bottom of the melting crucible and further bodies of the same metal together with pellets of KCl are placed on the striker plate beneath the electrodes which are lowered to contact the bodies which are melted by passage of current and volatilize the pellets to supply plasma for arc initiation.

Abstract: 707,458. Digital electric calculating apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 20, 1952 [Feb. 24, 1951 ; June 11, 1951], Nos. 4530/51 and 13748/51. Class 106 (1) A carry circuit comprises first and second multi cathode gas-discharge tubes, means for applying a pulse train to the first tube to step the discharge, means for generating an output pulse when the discharge reaches the output electrode of the tube, a gate circuit operated by the output pulse to pass a carry pulse, generated after the termination of the pulse train, to move the discharge in the second tube, and means for restoring the gate circuit. Multi-cathode tubes 34, 33 form the units and tens denominations of a totalizer into which entries are made from a similar pair of tubes 32, 31, as described in Specification 699,696. The ten pulse pairs necessary for performing this operation are provided by a pulse generator 46, and if during this period, the discharge in tube 34 appears on the zero output cathode 39, a pulse is delivered to fire a cold-cathode discharge tube 40, thus registering the fact that a carry must be made to the tens denomination. A double triode 41, normally L.H. side conducting, is made R.H. side conducting by rise in potential at the cathode of tube 40, and when a pulse is delivered at the cathode of valve 41 by the generator 46 at the "carry" time in the cycle it causes a drop at the anode 43 which delivers a pulse to the "tens" multicathode tube 33, and also extinguishes the tube 40: this, in turn, causes lowering of the voltage on the R.H. grid of tube 41 thus returning the tube to the L.H. side conducting state and returning a "finish" signal to the generator on line 45. A circuit 38, similar to the circuit 37, may be arranged to transfer a unit (" fugitive one ") from the highest to the lowest denomination during subtraction by complementary addition. An alternative arrangement of the circuit 37 in which the tube 40 is extinguished by a separate pulse in its anode circuit, is also disclosed.

Abstract: 635,359. Luminescent materials. CINEMATELEVISION, Ltd., and HEAD, R. B. Feb. 20, 1947, No. 5002. [Class 39 (i)] A luminescent material comprises essentially oxygen, sulphur, an alkaline earth metal and one or more of the elements cerium, yttrium, or dysprosium, and is prepared by heating together an alkaline earth compound, a compound of the said elements and sulphur. The alkaline earth metal is preferably either calcium or strontium. The element cerium, yttrium or dysprosium is preferably in the form of the hydroxide, oxide or nitrate. In one example, finely-divided calcium hydroxide is mixed with iron-free sulphur and a small quantity, <.25 per cent of the agglomerating agent, ammonium fluoride, and an aqueous solution of a salt of cerium (.05-.5 per cent) is added to make a paste which is dried and heated in an inert atmosphere for two hours. The residue is lightly ground and heated at 1100‹ C. in an inert atmosphere for a further two hours, followed by ball milling and annealing: In another method, strontium monohydrate and calculated quantities of nitrates of cerium, yttrium or dysprosium and ammonium fluoride are heated together in an alumina crucible, the strontium oxide obtained being then heated with sulphur. The fluorescent materials are of short afterglow with a fluorescing colour of yellow-green to bluish-green (cyan). Activation by dysprosium gives white to light buff fluorescence.
