Title: Improvements in or relating to the separation of solid materials of different specific gravities
IPC: B03B9/00
Filed: 1951-05-01
Abstract: 712,104. Washing granular material. COLLIERY ENGINEERING, Ltd., and NEEDHAM, L. W. June 26, 1952 [May 1, 1951], No. 10193/51. Class 82 (2) Solid materials are separated according to specific gravity by a combination of jig and sink- and-float treatments. The separating medium is recirculated for use in the sink-and-float apparatus, the washery water is recirculated for use in the jig, the discharge of at least one fraction of the sink-and-float apparatus is washed by the washery water to remove adhering medium solids, and the water is then treated to recover these solids for re-use. As shown in the Figure, all the coal is first jigged and then the larger particles of clean coal are screened and passed to the sink-and-float separator, the underflow from the screen (which comprises virtually all the water discharged from the jig) being fed into a canal into which the floated coal is discharged. The mixture of clean coal of all sizes is then classified in the normal manner, the under-flow being thickened and the supernatent liquid returned to the washer circuit. Froth flotation may be used to recover the very fine coal particles. The sink fraction from the float- and-sink separator may be screened, the underflow going to the canal, and the oversize particles either being crushed for return to the beginning of the circuit or discharged. As the shale has been removed in the jig, the sink fraction comprises middlings which may be sprayed off whilst being screened, washery water being used. In a modification (not shown), the coal is initially screened and the small particles (half inch and under) are jigged, whilst only particles over half inch are floated. In this case the shales from both processes are sprayed off and discharged. If desired, the fractions from each separation process may be treated in separate canals, in which case the canal handling the floated fraction drives the wash water from clarified water taken from the exit to the canal down which the washery water flows.

Title: Improvements in and connected with respiratory apparatus
IPC: A62B7/00
Filed: 1928-04-04
Abstract: 297,808. Deutsche Gasgl³hlicht- Auer - - Ges., and Hanseatische Apparatebau Ges. vorm. L. von Bremen. & Co. Sept. 29, 1927, [Convention date]. Respirators. - In closed-circuit respirators the excess pressure in the apparatus is relieved through an aperture opened positively by the action of a member adapted completely or partially to close the breathing circuit, for example the exhaling valve. As shown in Fig. 1a the exhaling valve t, co-operating with a seating d to control the breathing circuit, has also a seating d' upon a pipe f leading to a relief tube of capillary dimensions through which excess air is passed when the valve t opens. The valve t may comprise a disc or flexible membrane seating upon the ends of concentric tubes forming the breathing circuit : in these constructions the pipe f communicates with the valve casing. As shown in Fig. 5 a conical relief valve s is connected by a rod c with a resiliently mounted disc q displaceable by the current of exhaled air and moving into an enlarged part u of the breathing pipe. This device may be positioned close to the breathing bag and may take the place of an exhaling valve. In another construction a disc relief valve is connected by a rod directly to an exhaling valve such as t, Fig. 1a. Where a separate relief valve is provided this valve may be made to communicate with a relief tube such as f. In order to prevent blockage of the capillary portion of the relief tube by dirt or condensation this portion may be arranged in a protected position and in close juxtaposition to the filter cartridge.

Abstract: 990,212. Concrete mixers. P. AUGUST. March 15, 1963 [March 16, 1962], No. 10422/63. Heading B1C. [Also in Division B8] A concrete mixer of the type in which the mixing container 10 takes the form of a guided skip-hoist discharging into a storage hopper 55, is mounted upon a framework which can be tilted about a pivot-point 77 for transfer to a travelling carriage. As shown in Fig. 4, the mixer frame is pivoted at 70 to the end of the carriage, which is jacked up at 72, 73 and provided with retractable side extension members as at 69 carrying between them a cable guide roller 71. Cables 78, 80 are attached to the mixer frame at 79, 81 and their other ends secured to coaxial winches 75 and 76, Fig. 3 (not shown). By operating the winches in opposite directions the mixer may be tilted on , to or off the travelling carriage. Alternatively a differential winch and single cable may be used. The mixing container 10 is raised and lowered by a reversible motor 18, being guided by rollers 9, 12 on rails 5, 7, 8 and having an independent motor 14 for rotating the agitator (not depicted). Water is supplied in metered quantities by the displacement batching device 25 described in Specification 952,566, and is distributed across the width of the mixing container by the perforated header 50. The cycle of operation of the mixing container is automatic. Water discharge is initiated by mechanical, electrical, electro-mechanical or hydraulic linkage upon the container arriving at. its bottom position ; a switch 52 arrests its ; downward movement until sufficient water is available in the discharge tank, and a switch 19 stops the winding motor 18 when the cable 17 becomes slack. The container remains for a pre-selected time in its lowermost position, during which time solid materials are loaded into the charging aperture 15, and is then raised. If the storage hopper 55 is full, its weight actuates a switch 58 and the container is stopped in its upward travel by a switch 59. When the hopper can take additional material, the container completes its upward movement, is discharged through the discharge opening 16 by tilting caused by the configuration of the guide rails, and returns to its lower position.

Title: Improvements in weighing scales
IPC: G01G1/26
Filed: 1923-04-17
Abstract: 221,839. Marks, E. C. R., (Toledo Scale Co.). April 17, 1923. Computing-apparatus; indicating-mechanism.- A weighing scale comprises a beam lever, a second lever and movable means supported by the second lever so that no load shall be imposed by the movable means on the beam lever and adapted to connect the second lever to the beam lever at varying distances from the pivot of the latter, so that, while the beam lever assumes different positions corresponding respectively to the weight of various loads on the scale, the second lever is movable to positions corresponding to such weights multiplied by selected prices per unit of weight. As applied to the "fan type" of automatic weighing machine, Figs. 1 and 2, the scale beam 4 carries a graduated price-per-lb. beam 18 bearing a slide 23. Above the beam 18 is a rod 17 carried upon one end of a lever 16 which is pivoted upon uprights 2, 15. The rod 17 carries a slide 21 arranged vertically above and coupled to the slide 23. The operator may, by adjusting a sliding frame 39, move the slides 21, 23 simultaneously along their beams whilst maintaining their vertical alignment. The displacement of the lever 16 thus depends partly upon the adjustment of the poise 23 on the price scale and partly upon the displacement of the scale beam 4 under the influence of the load on the scale pan. The rear extremity of the lever 16 carries a narrow transparent chart 26 bearing a single row of graduations representing money values. A lamp 28 projects an image of the adjacent portion of the chart 26. via a lens 29 and two mirrors, on to a ground glass screen 32, thus affording an indication of the total cost of the goods adjacent to the weight indication afforded by the pointer 10. In a modified machine, Fig. 6, the weight is indicated optically on a ground glass screen 54a alongside the money value indications. This is effected bv means of a transparent chart 50<a> on the scale beam co-operating with a lamp 51a, lens 52<a>, and mirror 53<a>, the optical arrangements for the money value indications being similar to those already described.

Abstract: 105,471. Bullivant, F. A., and Selby, G. M. June 29, 1916. Breaking-pieces for relieving strain. - One of the jaws of a cable-stopper is held in position by a breakmg-piece which releases the jaw on the occurrence of excessive stress on the cable. The cable-stopper is intended for use on mine-sweeping vessels and for analogous hauling or dragging operations. As shown in Fig. 1, the cable 10 is gripped between a movable jaw 5 and a fixed jaw 4 is normally held by a breaking-piece in the form of a stud with a reduced neck 12<a>. On the occurrence of excessive stress, the stud 12 breaks and the jaw 4 falls away. In a modification the jaw 4 is supported from behind on toggles, and the stud 12 has an annular collar bearing against the outerside of the frame lug 11, the collar being sheared off the stud when the cable is excessively strained. In this case the movement of the jaw 4 is limited by engagement of the head of the stud engaging with the lug 11.

Abstract: 241,112. British Northrop Loom Co., Ltd., (Northrop Loom Co.). April 25, 1925. Weft, cutting; shuttle-boxes; shuttles" changing bobbins and other weft carriers in, automatically.-In weftreplenishing looms, the spent weft end leading from the weft carrier is engaged by thread parting and clamping means adapted to enter an opening in the top of the front wall of the shuttle box tu part the weft and to clamp the end leading to the selvage, and on the retreat of the lay, to withdraw the spent weft end over the top of the shuttle box. When weft-replenishment is called for, the shuttle feeler 20, Fig. 9, advances, and an incline 62 - thereon engages the weft a extending between the selvage and the shuttle eye, and thereby raises it between the shuttle and the front 56, Fig. 10, of the shuttle box, which is inclined forwardly of the lay towards the selvage to provide the requisite space when the shuttle is boxed. A thread clamping and parting device movable in a guide 23 is moved through apertures 55, 79 in the shuttle box front and the shuttle by give-way mechanism connected to the shuttle feeler, the motion being limited by a stop 52 adapted to engage the lay. The weft parter and clamp comprises two fixed members between which is pivoted a movable parter and clamp 29 having a fibrous surface to co-operate with one of the fixed members to clamp the thread, the other side of the part 29 co-operating with the other fixed member to part the weft. During the motion of the thread parter and clamp towards the shuttle box, a projection 66 on the movable member 29 engages a trip 67 to open the parter and clamp to receive the weft. When the transferrer 9 is operated to effect replenishment, a depending spring-controlled arm 71 on the transferrer engages the projection 66 to turn the member 29, and thereby to clamp the weft extending from the selvage and to sever it near the shuttle eye, the end leading to the weft carrier 80 passing backwardly through the eye when the spent carrier is ejected. After replenishment, the thread parter and clamp are moved forwardly to the position shown in Fig. 10, an inwardly and upwardly inclined part 63 of the shuttle box front leading the clamped weft end over the top of the shuttle box and turning it about the cloth selvage as a centre. The weft is then severed by.the usual temple threadcutter 4.
