Title: Improvements in or relating to pipe tongs for making and breaking well pipe joints
IPC: E21B19/16
Filed: 1948-05-11
Abstract: 656,738. Screwing-up and unscrewing wellpipe sections. GRABLE, D. B., and JACKSON, J. M. May 11, 1948, No. 12902. [Class 83 (iii)] Pipe tongs for making and breaking well pipe joints comprise upper and lower body sections having aligned recesses to receive a pipe, lateral openings in the sections through which the pipe may enter upon movement transversely of the pipe, each of said sections including a lever extending outwardly from the pipe, interlocking elements on the sections for supporting one from the other while permitting relative oscillation thereof about the pipe axis, pipe gripping means carried by each section and fluid-pressure actuated means carried by the tongs and operable between the levers to effect said relative oscillation. The upper section 11 carries pipe-gripping elements comprising fixed-jaw inserts 28, Fig. 2, and a movable jaw 40 connected to the rod 46 of a piston and cylinder device 45. The lower section 12 has a similarly operated movable jaw 55 but one of the opposite gripping elements 30 is backed by springs 33 and stands proud of fixed-jaw inserts 31. The outer ends of the two sections are connected to the piston and cylinder respectively, of an air-operated power means for producing relative movement between the sections. A swivel joint for this movement is made, after the sections have been passed transversely over a pipe joint J, Fig. 1, by a split ring 35, Fig. 2. A spinner mechanism 22 is slidably carried on the upper section and includes a depending bracket 50 connected through a compression spring 48 with the piston 46 of the upper gripping cylinder. The wheel 62 of the spinner is driven by gearing from a fluid motor or turbine 65. Spring-pressed rollers 88 support the pipe 16 opposite the spinner wheel. A control box 73, Fig. 1, enables air at low-pressure to be supplied, firstly, to the gripping cylinders which brings the spinner roller and light gripping means into operation to take up the screwed joint J to a snug condition. Secondly, highpressure fluid is next introduced to operate the main gripping elements and the cylinder 56 is put under pressure to produce relative rotation of the upper and lower sections to complete the tightening of the joint.

Title: Improvements in or relating to thermionic valves
IPC: H01J21/02
Filed: 1937-05-07
Abstract: 500,352. Thermionic valves. BULL, C. S. May 7, 1937, No. 13037, [Class 39 (i)] In order to reduce the " shot " noise in a hard electron discharge valve the electron emis sion from the cathode is arranged to be in the form of a plurality of separate streams so that when a space charge limited current flows the individual space charges of the streams are substantially prevented from interacting. In the case of directly heated cathodes, fins or projections 13 may be attached at intervals to the cathode 9 as in Fig. 2, or the cathode may be made non-emissive over portions as in Fig. 3 (not shown). An indirectly heated cathode may have non-emissive sections to produce the separation of the electron streams. If the valve has a grid the separation may be produced by provision of partitions 17 on the grid 16 which project towards the cathode as shown in Fig. 5. Alternatively the partitions may be mounted on the cathode and project towards the grid, Fig: 6 (not shown). The separation of the streams may also be obtained by blocking up portions of the grid or providing closely wound sections, Figs. 7 and 8 (not shown). Reference has been directed by the Comptroller to Specifications 424,035, 448,101, 463,421, 475,620; and 477,850, (as open to inspection under Sect. 91].

Title: Improvements in or relating to electric discharge devices
IPC: H01J17/06
Filed: 1932-05-09
Abstract: 385,191. Discharge apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 9, 1932, No. 13346. Convention date, May 7, 1931. [Classes 39 (i) and 40 (v).] To reduce damage to the cathode of gas-filled thermionic devices by ionic bombardment before the cathode has heated up when the device is switched on, an openwork electrode or grid shields the cathode from the anode to prevent the discharge initially and is heated by the cathode until electrons are emitted thermionically by the grid to allow the discharge to start. The grid may comprise a perforated end 8 of a metal cylinder 7 forming a heat shield around the cathode cylinder 6. The cylinder 6 is of an alloy containing thorium, uranium, or other electron-emissive material or its inside or whole surface is coated with emissive material such as an alkaline earth compound. The structure 7, 8 is also formed of an emissive alloy or coated with emissive material. The cylinders 6, 7 may be connected to opposite leads 4, 3 of the cathode heater 5 to bias the cylinder 7 negatively when the device is switched on, this negative bias preventing the discharge until the structure 7, 8 becomes sufficiently hot to emit electrons. The apertures in the grid 8 are such that the field of the anode 2 does not ionize or excite the gas or vapour inside the cylinder 7. Circuit elements such as ohmic resistances or inductances with or without capacities may be connected between the parts 3, 7. The device may serve as a rectifier or time-lag relay and the time-lag may be adjusted by applying control potentials to the part 8.

Title: Improvements in and relating to the classification of solids in suspension
IPC: B03B5/54
Filed: 1937-05-13
Abstract: 488,745. Wet-separating apparatus. TRIGGS, W. W. (Dorr Co., Inc.) May 13, 1937, No. 13583. [Class 82 (ii)] [Also in Group I] A classifier for separating solids according to size, specific gravity &c., which may be used in the treatment of sewage, comprises an elevator mechanism consisting of a head pulley and an endless flexible belt which is trained over and driven by the pulley and depends into the suspension in the tank and is provided with blades to raise settled solid matter, there being arranged within the bath and adjacent to the path of the belt a quiescent zone from which the suspended particles can overflow without disturbance from the passage of the loads picked up by the belt. The classifier shown in Fig. 3 comprises a tank 11 in which works a conveyer formed by an endless flexible band 18 suspended from a pulley 17 and having blades 20 to raise settled material. The blades are preferably formed with two arms, one of which 21 is attached to the belt and is preferably curved to correspond with the curvature of the pulley 17. The outstanding arms preferably make an angle of about 45‹ with the belt, the blades forming open-ended pockets in which a certain amount of stratification occurs before emergence from the liquid and from which liquid readily flows off after emergence. Between the blades and the sides of the tank are baffles 27, 28 which may be formed by an extension of the elevator casing H and which define a relatively quiescent zone from which suspended solids overflow an adjustable weir 14 into a launder 15. The depth of the baffles is such that the larger intermediate sized solids are not carried over the weir 14. The material to be classified is fed into the agitation zone by a shoot 13 and baffle 43, and the material elevated by the conveyer is preferably washed out of the pockets by jets from nozzles 41 and is deflected by a member 25 to a launder 26. In the form shown in Fig. 4 the relatively quiescent zone from which overflow of suspended solids occurs is between the runs of the belt, the inner surface of which is made smooth. An overflow launder 38 with weirs 37 is provided in the quiescent zone, inclined baffles 39, 40 being provided to reduce agitation of the liquid. The blades on the conveyer are made of heavy metal, e.g. cast iron or steel, and are spaced closely to give rigidity to the belt. The agitation produced by the conveyer can be controlled by varying the speed or the diameter of the pulley 17, a pulley of large diameter being preferably used in the form shown in Fig. 4. The classifier may be used in closed circuit with a grinding mill, in which case the pulley 17 may be arranged at such a height that the sands are returned to the grinding mill by gravity.

Title: Glassware blowing mechanism for forming hollow glass articles
IPC: C03B9/447
Filed: 1940-09-02
Abstract: 541,440. Glass manufacture. BRIDGES, E. G. Sept. 2, 1940, No. 13756. [Class 56] Relates to mould opening and closing mechanism for a glass-blowing machine of the kind described in Specification 386,012, and consists in providing mechanism for stopping the machine if a mould fails to open. Figs. 1 and 2 show part of a double-table machine comprising a mould table 10 rotatable about a vertical column 11 and carrying sectional finishing moulds 25, the mould halves being attached to holders 26 which are pivoted on pins 27. The table 10 moves the mould to a transfer position T, then through a blowing- region B to a discharge position D. When the moulds move from D to T they close around a suspended parison. Each mechanism for opening and closing a mould includes a roller 31 resiliently connected by a spring 32 to a yoke 29 which is linked to the mould holders 26. The roller 31 is adapted to engage a cam 33 for keeping the mould closed during its journey from position T to a point just short of position D, where it enters a cam 51 that partly opens or " cracks " the mould. At position D, the roller enters a forked portion 53, 57 formed on a slide which is secured to the piston rod of a pneumatic cylinder 54. The cylinder draws the roller towards the centre of the table 10 and opens the mould pulley. During the movement from D to T, the roller rides in a trackway 34 of a cam 35 which partly closes the mould around a parison on the adjacent mould table. When the mould reaches position T, the roller moves into the fork 45 of a slide 44 which is moved outwards by a pneumatic cylinder 40 to close the mould. In order to ensure that the fork 45 is in position to receive the roller 31, a triangular plate 46 is pivoted at 47 to the cam 35, and also at 48 to the slide 44. An inclined edge 46a of the plate lies in the trackway 34, and the roller 31 engages this edge and moves the fork 45 inwards into position to receive the roller. If the fork 53, 57 of the slide 52 is not in its outer position to receive the roller 31 at position D, the roller strikes the part 57, which is pivoted to allow the roller to pass, and as the unopened mould is carried past position D, the roller 31 engages the outer edge 36 of the cam 35, and the cam keeps the mould closed. Between positions D and T, the roller 31 engages the piston rod of a valve 60 in the compressed air line, and operates the valve to admit air to a cylinder that opens a clutch in the driving shaft and stops the machine.

Title: Improvements in the treatment of spent catalysts in hydrocarbon conversion processes
IPC: B01J8/18
Filed: 1940-09-04
Abstract: 539,844. Hydrocarbon conversions. STANDARD OIL CO. Sept. 4, 1940, No. 13835. Convention date, Sept. 13, 1939. [Class 2 (iii)] [Also in Group III] In the catalytic cracking or conversion of hydrocarbons adherent oil is removed from the spent catalyst by treatment with hot, normally gaseous hydrocarbons, e.g. natural gas or refining gases, at a temperature approximating to that of the conversion process, e.g. 750-950‹ F. The invention is particularly applicable to a cracking process wherein the vapour of the feed stock evaporated in still 13 is mixed with powdered catalyst supplied at 14 and injected into a reaction zone 15, the catalyst and the reaction products being subsequently separated at 17. The spent catalyst is injected into a column 22 by an injector 20 supplied with hot fuel gas, and as it falls over the baffles 23 it meets a counter-current of fuel gas admitted by line 24. The treated catalyst passes out by line 25 for re-generation and re-use. The fuel gas is freed from the oils absorbed by it in a tower 29 where it is washed with a part of the oil to be fed to the system, and is then re-circulated.
