Title: Improvements in or relating to axially applied wheel brakes, more particularly for furniture and domestic appliances
Inventor: ORD WALTER ARTHUR
IPC: B60B33/02
Filed: 1953-03-25
Abstract: 734,807. Disc brakes. REVVO CASTOR CO., Ltd. March 25, 1954 [March 25, 1953], No. 8254/53. Class 103 (1). In a wheel and brake assembly comprising a pair of axially movable wheels rotatable about, and spaced apart along, a common axis, friction braking surfaces are disposed adjacent at least one face of each wheel and are applied by a common brake applying means so that the axial displacement of one wheel causes a similar axial displacement of the other wheel to effect braking of the latter. In the embodiment shown applied to solid rubber wheels 1 mounted on a common axle 2 and adapted for attachment to furniture or domestic appliances, two resiliently mounted brackets 3, spaced apart by rod 4, are secured to the underside of the piece of furniture or domestic appliance. Mounted on the axle 2 adjacent the outer face of each wheel is an end member in the form of a plate 5 which is retained by a nut 6. Between each wheel and the adjacent bracket 3 there is an axially movable plate 7 which carries a pin 8 extending through an aperture in the vertical arm of the bracket 3 to prevent rotation of the plate 7 ; the outer faces of these plates serving as braking surfaces for the wheels. In operation, when the actuating pedal 12 is depressed, the cam 9, attached to the pedal 12 and prevented from moving to the left by a rigid spacing tube 13, rotates on the axle 2 and forces the axially slidable cam 10 to move to the right to cause the adjacent plate 7 to engage the inner face of its wheel 1 so as to displace the wheel axially and force its outer face against the end plate 5. This axial displacement of the wheel causes the whole axle to be moved to the right through the brackets 3 until the opposite end plate 5 displaces the other wheel axially to force its inner face into engagement with the other plate 7. During the movement of the cam 10 to the right, its annular shoulder engages the inner face of the vertical arm of the supporting bracket 3 and flexes the bracket arm outwards. The bracket arm thus serves as a spring which tends to close the cams when the brake is applied.

Title: A combined recirculating air classifier and hot air drier
Inventor: JANICH HANS JURGEN
IPC: B07B4/02
Filed: 1969-02-14
Abstract: 1,215,914. Pneumatic classifier. POLYSIUS A.G. 14 Feb., 1969 No. 8265/69. Headings B2H and B2P. [Also in Division F4] A combined recirculating air classifier and hot air drier comprises a classifying chamber 2 in which feed material to be classified is distributed centrifugally by a plate 4 carried by a drive shaft 3 on which is also mounted a fan 5 for generating a classifying air current. A coarse fraction receiving chamber 8 consisting of upper and lower cones 9, 10 is located below the chamber 2. A fines-receiving chamber 7 surrounds the chambers 2, 8 and is in communication with the chamber 2 through the fan 5 and through a louvre 6 so that classifying air can be recirculated from the chamber 7 through the louvre 6 into the chamber 2. Radial guide vanes 12 are disposed in the annular gap between the cones 9, 10 and are surrounded by an annular chamber 14 to which hot air is supplied via an inlet duct 15. Below the chamber 14 the finesreceiving chamber 7 is provided with an air quiescent zone 16 which communicates with the outside through an air outlet 17. In operation, the hot air is guided tangentially into the cone 9 by the vanes 12 so that as it ascends in the chamber 2 it whirls and dries the descending coarse fraction and at the same time separates fine material that still adheres to the coarse particles. From the chamber 2 the cooled hot air together with the classifying air and the entrained fibres enter the chamber 7, a part of the total air being recycled through the louvre 6 into the chamber 2 and the remainder being discharged as exhaust air through the quiescent zone 16 and the outlet 17.

Title: Improvements in or relating to thrust bearings
IPC: F16C17/04
Filed: 1946-03-18
Abstract: 622,544. Thrust bearings. KAPELLA, Ltd., and REASON, R. E. March 18, 1946, No. 8315. [Class 12 (i)] To compensate for slight manufacturing inaccuracies in the parts of sliding thrust bearings as used for the axial locating of machinetool spindles, two rings of wedge-form are appropriately angularly adjusted around each other and then secured in position to provide one of the elements of the thrust bearing. The spindle may be of the form described in Specification 621,126, having taper journal surfaces co-operating with bushes axially adjustable within the housing for the spindle and bushes, thereby to adjust the radial clearance in the journal bearings, the spindle being fixedly located in the axial sense by a flange on the spindle being engaged between thrust bearing members fixed on the housing. As shown in Fig. 5, the flange on the spindle, provided by a separate member A<SP>1</SP> secured on the end of the spindle, runs in a groove provided between two thrust-ring members, one of which members is a composite ring made up of two rings D, E of wedge-form, as indicated by the wedge angles b, c, these two rings being appropriately angularly adjusted around each other to provide a resultant wedge angle such as to compensate for the inaccuracy of the housing shoulder from a plane truly perpendicular to the spindle axis. Clamping of the rings in angularly-adjusted position and the securing of the whole assembly of the fixed rings of the thrust bearing is effected by bolts G<SP>1</SP>, the adjustable rings being slotted to permit adjusting movement relatively to the bolts. A sleeve H holds the rings against radial displacement during adjustment. Lubricant is supplied to a hollow boss J<SP>1</SP> of an end cap J secured to the spindle, and passes to ducts J3 in the shaft collar A<SP>1</SP> thereby to lubricate the thrust surfaces, and to the hollow interior of the shaft, and thence by radial ducts J2, thereby to lubricate the journal surfaces. Specification 621,126 is referred to.

Patent GB-659283-A (GB)
Title: Improvements relating to the treatment of sulphide ores containing nickel
IPC: C22B23/00
Filed: 1949-03-30
Abstract: A nickeliferous pyrrhotite concentrate obtained from a sulphide ore is roasted between 650 DEG  and 870 DEG  C. to yield a porous product in which substantially all the iron and nickel are present as oxides, and this product is then reduced under such conditions that substantially all of the nickel but none of the iron is reduced, and the nickel is separated from the iron oxide by ammoniacal leaching. A suspension roasting is preferably employed, the finely divided concentrate and air or oxygen-enriched air being injected into the upper part of the chamber in concurrent flow, 25-75 per cent excess of air over that required to convert the iron sulphide to iron oxide and sulphur dioxide is employed.  Reduction may be effected in a rotary kiln at 760-870 DEG  C. in an atmosphere which, in contact with the reduced material as it leaves the kiln, is such that the ratio CO2+H2O : CO+H2 is 1.5-3 : 1.  The reduction period varies from ten minutes to eight hours.  When reduction is complete, the product should be cooled in a non-oxidizing atmosphere to below 200 DEG  C. A suitable leaching solution contains 8 per cent ammonia and 4 per cent carbon dioxide, and the leaching is effected in the presence of air or oxygen.  The ores treated usually consist of pyrrhotite, pentlandite and chalcopyrite, and a method of concentrating the pyrrhotite, including froth flotation and magnetic separation, is described (see Group II).  The Specification as open to inspection under Sect. 91 refers also to fluid-bed roasting.  This subject-matter does not appear in the Specification as accepted.ALSO:Ores consisting of pyrrhotite (FeS2), pentlandite (NiFeS2) and chalcopyrite (CuFeS2) are treated for subsequent recovery of the nickel by a two-stage froth flotation operation using a potassium amyl xanthate collector, a pine oil frother and sodium silicate as a dispersing agent to recover concentrates of the bulk of the chalcopyrite, pentlandite and precious metal minerals, and of pyrrhotite.  The latter is subjected to magnetic separation, and the concentrate, still containing nickel and copper, is ground and subjected to a further flotation treatment using potassium amyl xanthate at about pH 11 to float substantially all the remaining chalcopyrite, pentlandite and precious metal minerals and to depress a clean nickeliferous pyrrhotite concentrate, which is deslimed and dried.
