Title: Apparatus and process for separating a concentrated slurry and a filtrate from a solids-containing fluid
IPC: B01D29/62
Filed: 1975-02-07
Abstract: 1497922 Filter for concentrating slurry ARTISAN INDUSTRIES Inc 7 Feb 1975 [13 May 1974] 5368/75 Heading BID A filter comprises a housing with a slurry inlet 20 at one end and an outlet 22 for concentrated slurry at the other, enclosing a plurality of annular filter elements 30 with flat radially oriented filter surfaces and a relatively rotatable assembly of discs 36 located between the elements 30 and carrying blades 58, 58A directed towards the filter surfaces, the blades serving firstly to limit the build up of filter cake on the surfaces to a predetermined thickness so that it acts as a filter aid and secondly to direct slurry in a sinuous path radially inwards across one surface of each filter element and radially outwards across the opposite surface. In Fig. 1 the filter elements are fixed and the discs 36 rotate on shaft 34, but filter elements and housing could rotate relative to fixed blades or alternate filter elements could carry blades (Fig. 6 not shown) and rotate between fixed elements. In Fig. 1 each filter element is a solid annular disc with circumferential drainage grooves 68 (Fig. 3) opening into three radial bores 70 which discharge filtrate into a pan 86 beneath the housing. The filter elements each carry a ring section 26 of the housing on their outer peripheries, and bolts 40 clamp the elements, sections 26 and housing ends 16, 18 together. Each face of each element is covered with a sheet of polyester cloth, clamped thereto by rings (78, 78A, Fig. 5 not shown). Discs 36 are flat and carry blades 58, 58A on opposite sides, these blades being arcuately curved in opposite directions (Fig. 2, not shown) to effect the slurry movement required. Discs 36 may also have by-pass apertures adjacent shaft 34 and additional blades 94 on their outer edges. The endmost discs 36A and 36B have blades 58 on one side only and carry on their other sides paddles 110, 112 which match the shapes of the end spaces in the housing and prevent solids settling there. Disc 36B at the concentrated slurry outlet end may be replaced by a structure as in Figs. 9, 10 (not shown) comprising four straight radial blades extending between a central hub and a peripheral ring, these blades serving as blades 58 and paddles 112. Pump 19 delivers slurry at up to 375 p.s.i. Valves 24, 90 control outlet of slurry and filtrate. Clearance between blades and filter cloths may be <SP>1</SP>/ 32  to <SP>1</SP>/ 16  inch. Other dimensions are exemplified. Gaps between adjacent filter elements 30 may be equal or vary lengthwise of the housing, possibly decreasing in the direction of flow or widest half way along the housing. This can be achieved by varying thicknesses of elements 30 and discs 36.

Title: Stop motion for spinning and like textile frames
IPC: D01H13/18
Filed: 1945-03-05
Abstract: 589,884. Spinning. FRASER & SONS Ltd., D., and FRASER, G. S. March 5, 1945, No. 5390. [Class 120 (ii)] A stop-motion mechanism for spinning and like textile frames, adapted to act on breakage or failure of the material, comprises a detector 1, Fig. 1, fixed to or unitary with a block 2 which is mounted on a fixed pivot or provides a bearing surface for a fixed knife-edge 3; a link 5 having normally inseparable pivoted or knife-edge connection with the block 2 connects it with one arm 7 of a manually operable lever having a fixed pivot at 8, the other arm 9 having a weighted lever 10 pivoted on it. A nose 11 on this lever contacts a lever 12 carrying the retaining pressing roller 14 and tends to urge it against the roller 15, The link 5, knife-edge 3 and block 2 form a toggle which is latched when the detector is held by the material A. When, on failure of the material, the detector arm 1 swings outwardly, the toggle breaks and the knife-edge slips off the block 2, the arm 7 rises and the arm 9 falls, so that the nose 11 rides off its abutment and the lever 12 and roller 14 are released. At the same time a nipping element 17 on an extension of lever 10 contacts a co-operative element 18 to grip the material. In a modification, Fig. 3, the link 5' is pivoted on a crooked lever 21 having a stationary pivot 22. A three-armed lever 24 weighted at 26 is pivoted on lever 21 at 23, and its arm 27 has pin and slot connection at 28, 30, with a further lever 29 carrying the arbors 13<1>, 32 of the retaining pressing roller and drawing pressing roller. A tension spring 33 tends to disengage these rollers from their co-operating rollers 15<1>, 20'. On the toggle being broken, the weight 26 causes levers 21, 24 to swing about the pivot 22, and a finger 34 on lever 24 engages and slides down the fixed inclined surface of a member 35, thus retracting the pin 28 and allowing the spring 33 to pull the lever 29 carrying rollers 14<1>, 19' away from the rollers 15', 20' until stopped by the abutments 36, 37. The mechanism is reset by the handle 25. According to the Provisional Specification the link may be connected to the manually operated lever through a bracket, and is limited in its pivotal movement in one direction by an adjustable stop on the latter. Also, the retaining pressing roller may be journalled in a bearing block slidable in a slot in the arm engaged by the nose of the weighted lever, and entered by a spring tending to urge the roller away from its companion when the nose of the weighted lever falls.

Title: Improvements in or relating to multi-part glass articles and method of manufacturing same
IPC: C03C27/08
Filed: 1936-02-25
Abstract: 461,465. Glass manufacture. OWENS-ILLINOIS GLASS CO. Feb. 25, 1936, No. 5656. Convention date, May 13, 1935. [Class 56] A method of making a glass article from two or more parts consists in moulding the parts from molten glass, applying a metallic bonding medium to one of the surfaces to be united while the parts are still at a temperature above 1000 F., bringing the surfaces into contact with one another, and then annealing the assembled structure. The method may be used particularly for making building blocks or electric insulators, and the bonding medium is preferably aluminium or aluminium-silicon alloy although copper may be used. Boric acid and borax, or lead borate and carbonate, stannic chloride, or copper sulphate and oxide may be used in conjunction with the aluminium as a flux for the surface of the glass. In making a glass brick, two hollow sections 16, Fig. 1, are pressed, and while still hot their edges 18 are dipped into a bath of molten aluminium or aluminium-silicon alloy, or a strip of very thin aluminium foil 19 is placed on one of the edges 18. The sections are then assembled with the edges in contact with one another, and they are pressed together until the aluminium is fused and absorbed to some extent by the glass so that the sections become welded together. An insulator may be made by pressing two parts 21, 22, Fig. 5, which are assembled with a layer of aluminium 20 between them and united by pressure.

Title: Improvements relating to centrifugal clutches
IPC: F16D43/12
Filed: 1936-02-27
Abstract: 471,155. Friction clutches. HINDEN, H. Feb. 27, 1936, No. 5834. [Class 80 (ii)] In a centrifugal friction clutch for motor vehicles, a spring 5, through which engaging pressure is transmitted from a centrifugal weight 3 to a lever 4 from which it is transmitted to the clutch presser plate 1, is arranged between an abutment 11, Fig. 1A, moving with the weight 3, and an abutment 20 moving with the lever 4, the abutment 20 being interposed between the spring 5 and another abutment 10 moving with the abutment 11. The initial compression of the spring 5 is such that the abutment 20 is maintained in contact with the abutment 10 during idle running and until a predetermined pressure, which allows the absorption of the maximum engine torque, is transmitted to the plate 1. Above the speed at which this occurs, the spring yields, as shown in Fig. 1C, the amount of yield diminishing progressively as the clutch discs wear. The movement of the weight 3 is limited by a stop 8 so positioned that. when the clutch discs are fully worn, the yield of the spring is zero. A tension spring 7, acting in opposition to the engaging pressure, ensures disengagement at idling speed, and, as the clutch discs wear, its additional extension counterbalances the increase in centrifugal force of the weight caused by the additional movement of the latter. Manual disengagement may be effected by pressure at the point d. In the form shown in Fig. 3A, the spring 7 acts in compression and the abutment 20 is formed on a link 12 connected to the lever 4. Figs. 4A and 4B show a constructional embodiment of the arrangement shown in Fig. 3A. The abutment 11 is adjustable on the slidable rod 6 connected to the weight 3, and manual disengagement is effected by pressure, through a ball thrust bearing, on a disc 14 which carries pins 21 coacting with one of the three arms of the lever 4. In a modification, the abutments 10, 11 move with the lever 4 and the abutment 20 with the weight 3.
