Title: Improvements in or relating to the distillation and carbonisation of coal-oil mixtures
IPC: C10B55/02
Filed: 1935-01-22
Abstract: <PICT:0454011/III/1> Mixtures of solid carbonaceous materials, e.g. coal and oil are distilled and carbonized by feeding the mixture to a tray or container which is placed in an externally heated retort in which the mixture is coked at above 425 DEG  C. by heat received solely from the walls, floor, and top of the retort, the resulting gases and vapours being fractionated, the lighter fractions cooled to condense less volatile portions and the residual gases and vapours passed through scrubbing, refrigerating, sulphating and halogenating devices.  Coal fed from a hopper 2, oil preheated in a storage tank 7, and if desired, a zinc base or alkaline earth catalyst, are mixed in a tank 6 and fed, with or without preheating to 325 DEG  C., in a vessel 14, to a tray 57 which is then placed in a steel retort 21 where it is heated for six hours to 600 DEG  C.  Vapours pass off through a pipe 22, controlled by a valve 23 to give a slight positive pressure in the retort, to a fractionating column 18 from which heavy fractions are recycled through a cooler to the tank 7 while uncondensed vapours pass through a pipe 31 to a cooler 32, condensate from which is led to receivers 34.  Further condensible constituents are removed from the residual gases by passing these through a refrigerator 48 the condensate being collected in receivers 49, 50, 51, the gases finally passing through scrubbing, sulphating, and halogenating towers 53, 54.  Modifications are described in which (1) the gases are passed to a gas-scrubbing tower of the electrostatic precipitation or wet type in which the absorption agent may be gas oil, creosote, or the 150--200 DEG  C. fraction produced in the process; (2) the vaporous products from the retort are passed through a red - hot catalyzing tube packed with semi-coke produced in the process, zinc dust on a carrier, or with alkaline earths of the type described in Specification 449,603.  Specification 325,324, [Class 32], also is referred to.

Title: Improvements in and relating to a protective device for an alternating current system
IPC: H02H3/353
Filed: 1924-01-29
Abstract: 218,938. British Thomson-Houston Co., Ltd., (General Electric Co.). Jan. 29, 1924. Cut-out arrangements.-In a polyphase distribution system, in order to differentiate correctly between a sound line conductor and one which has become, earthed through a high resistance fault, the faulty phase is selected for isolation by means of a device having windings which carry current proportional respectively to the star and delta voltages of the circuit. As shown in Fig. 1 for a three phase system, the phases 1, 2, 3 are connected to the primary 4 of a potential transformer 5 having a secondary 7. A centrallybalanced three-armed relay G is employed to control, selectively, the relays 8, 9, 10 which when closed open the line switches 13, 12, 11, respectively. Each of the three arms of the relay 6 is acted on by two coils, as shown, the coils 14, 15, 16 being delta-connected to the windings 7 and coils 17, 18, 19 being connected in series with the resistances 20, 21, 22 across the secondary phase windings 7; that is to say, the windings 17, 18, 19 are star connected. By reason of the resistances 20, 21, 22, the currents in the windings 14, 15, 16 have an angle of lag relative to the currents in the windings 17, 18, 19 and, when a high or low resistance earth fault develops on one of the lines, the conjoint action of the two coils is reduced and the corresponding arm of the relay - engages the contact 27, 28 or 29 above it to open the corresponding line circuit-breaker. The faulty line, by similar means, may be short-circuited solidly to ground.

Title: Improvements in or relating to moulding presses
IPC: B28B1/10
Filed: 1931-01-26
Abstract: 371,828. Moulding bricks &c. in pressing-and-jigging machines. DANIELS, W. H., 174, Pestalozzistrasse, Heerdt, Dusseldorf, DANIELS, J., 28, Wandastrasse, and KOPPERS AKT.-GES., H., 29, Moltkestrasse, both in Essen, both in Germany. Jan. 26, 1931, No. 2583. Convention date, Jan. 27, 1930. [Class 87 (ii).] A jigging moulding-press fitted with apparatus for applying a top pressure to the material during the jigging operation, is constructed with the top pressure plate guided by and movable relatively to a ram which in turn moves relatively to the mould to apply the pressure. Figs. 1 and 2 show constructions in which the mould 2 is jigged by mechanism 4 (not shown) underneath the table 3. The guided ram 6 is raised and lowered by rack- and-pinion gearing 9, 10 operated through worm gearing by rotating the handle 16. The pressure plate 5 slides in the ram and is either connected thereto by the spring 53, or slides freely therein, in which case a hand-operated clutch 21 is used to lock it in set position relatively to the ram. In operation, the pressure-plate and ram are lowered as a unit until the plate contacts with the material. The clutch 21 then is released so that the weight of the plate is taken by the material. After jigging, the clutch is re-engaged and the unit raised again. The spring 53 when used increases the dead-weight pressure of the plate on the material. A hydraulic cylinder 22 strips the mould from the article through the agency of the rods 26 connected to lugs 30 on the mould, while the press-plate 5 holds the article on the mould table. Turnbuttons 45 normally centre the mould and hold it down on the table. For stopping the travel of the ram 6 on the upstroke as soon as the compression of the spring 53 is relieved and the block is ready to be stripped, a projection 130 on the ram, which engages a latch 69 on the downstroke and trips the shaft 70 by moving it axially against the pressure of a spring 75, re-engages the latch 69 and rotates the shaft, thus raising the pawl 76, Fig. 4, and freeing the block 77 to relieve the tension on spring 96. This allows the weaker spring 97 to disengage the sliding clutch member 88. A hand-lever 84 is used for resetting the clutch after the stripping operation. A heavier press is described in which seven pairs of springs are inserted between the mould plate and the ram. The ram in this case forms the movable cylinder of a hydraulic press which is moved relatively to a fixed ram. The return movement is performed by the cylinder 22, as before ; and the moulds are mounted on wheeled trucks and run into and out of the press. Clamps and wedges are used to fix the trucks during the moulding operation.

Abstract: 927,103. Lathe details. NATIONAL ACME CO. Jan. 23, 1961 [Feb. 2, 1960], No. 2595/61. Class 83 (3). In a multiple spindle automatic lathe, each of the workpieces 47 is mounted between a rotatable spindle 15 and a power actuated tail-stock 21, Fig. 4, is machined by stationary tools 58, and is supported during machining by a rest comprising a pair of rollers 41, movable towards and away from the work. A turret 18, indexable along with spindles 15 by rotation of a spindle carrier 14, supports the tailstocks and the work rests are slidably mounted in a collar 19 on the turret. Each work rest comprises a pair of rollers 41 carried on a slide 43, Fig. 7, slidable in collar 19, Fig. 10. The slide is urged towards the axis of the turret by springs 52, 53 in collar 19 which engage pegs 54 on the slide, and an adjustable stop 48 limits the outward movement of the slide. A sleeve 25 axially movable in an elongated aperture in slide 43 has wedge-shaped faces 27 which engage rollers 56 (not shown), on slide 43 so that as the sleeve moves axially in the work rest, rollers 41 move radially relative to a workpiece 47. A rod 26 carrying sleeve 25 is screwed to a turnbuckle 28 which has screwed thereto, a further rod 29 carrying a roller 31 which engages with a stationary face cam 32 fixed to a gear-box 16. A spring 36 urges roller 31 into engagement with cam 32, and a stronger spring 38 urges sleeve 25 to the left, Fig. 3, to move rollers 41 against the work, this latter spring also taking the thrust of the tool when the work is being machined. The six spindle positions I-VI, are shown indicated on cam 32, Fig. 12, the first position being the loading and unloading position, which is empty in Fig. 1. The spindle carrier 14 indexes in a counter-clockwise direction as seen in Fig. 1, and a clockwise direction as seen in Fig. 12, therefore the lowermost position in Fig. 1 is position II. Rollers 31 will engage cam 32 in positions III-VI, thus moving rollers 41 to support the work in these positions, but as the cam is interrupted at stations I, II, rollers 41 will be allowed to move away from the work for unloading &c.
