Patent GB-763272-A (GB)
Title: Improvements in the manufacture of cristobalite
Inventor: GREGORY ANDRE GEORGE
IPC: C03C10/00
Filed: 1954-03-23
Abstract: Cristobalite is prepared by fusing a siliceous material having a silica content not less than 99.5 per cent SiO2 such as sand, quartzite or crystalline quartz with more than 0.1 but less than 0.2 per cent of an alkali or alkaline earth metal mineralizer catalyst, calculated as oxide, in the form of an oxide or a compound giving rise thereto.  Sodium or lithium compounds are preferred.  The fusion may be effected by a batch process wherein the silica and added mineralizer in the wet state are progressively heated in an electric furnace using graphite resistors.  Alternatively a continuous process may be employed wherein the silica/mineralizer mix is fed down an electric furnace provided with horizontal graphite resistors. Relative movement may be effected between the resistors and the furnace bottom and a fused mass builds up below the resistors, which on cooling changes to cristobalite.  Specification 686,876 is referred to.

Abstract: 693,274. Mortar spreaders. CLARK. R. R. April 4, 1952 [April 4, 1951], No. 8684/52. Class 20(iv) A receptacle for spreading mortar on a wall preparatory to the laying of a course of bricks, has its side walls 5 stepped at 3 to provide bearing surfaces for a horizontally movable plate flooring 4 suspended by struts 23, 24, from a carriage 14, one end 16 of the carriage being provided with grooved wheels 15 which run on guide rails 17 adjustably screwed at 18 to the sides 5, and the other end 19 running on grooved wheels 20 which are rotatably supported in brackets 21 projecting from the end wall 22 of the receptacle 1. The lower edges 2 of the walls 5 project downwardly to provide supports 6 which are covered, e.g. with strips of rubber, to provide loops 12 below the lower edges of the support 6. The end wall 7 of the receptacle slopes inwardly at 8, the adjacent end of the floor 4 being provided with an, adjustable and replacable screeder 9 bent to correspond with the slope 8. The struts 23, 24, are slotted so that the flow 4 can be pulled up firmly against facings 13 on the bearing faces 3.

A hose coupling component for a hose having an embedded reinforcement 3 includes an end fitting 9 having a sleeve portion 8 and an internal, annular, axial projection 11, the end of the hose being bared to the reinforcement which is separated from the inner hose layer 1, passed through and bent back over a ring 5, and gripped between sleeve and ring. The projection 11 extends between the reinforcement and the inner hose layer which is held against the bore 12 of the fitting by an insert 15. The bore 12 is conical, or partly conical and partly cylindrical. The inner hose layer 1 is cut or ground to fit the bore 12. The insert 15 may be a close-coiled, squaresection spring, or it may be a rigid tube which has lateral openings or an outer portion of reduced diameter to allow fluid pre.ssure to act on the inner layer 1. The spring insert may have a rigid sleeve on its inner end. The sleeve 8 and annulus 11 may be separate from the fitting 9. The sleeve 8 and ring 5 are contracted on to the hose by swaging. In a modification the ring 5a, Fig. 4 has an outer end of semi-circular cross-sectional profile and a conical bore diverging towards its thin inner end. The fitting 9a has a complementary recess. When contracted the ring has a cylindrical form 5b parallel with the annular projection 11a. The cylindrical bore 12a of the fitting is in two parts joined by a shoulder 23. In a further modification an externally tapered ring 29, Fig. 5 clamps the reinforcement 3 against the tapered bore 27 of the fitting by a nut 30 screwing on to the fitting. The nut may screw into the fitting, and may, in addition, have a tapered projection engaging a tapered bore of the ring. If the hose has more than one tubular reinforcement the hose end is bared to the inner reinforcement. Alternatively all layers are removed except the outer reinforcement and the inner rubber layer. A supplementary ring may be located between the sleeve 8 and the reinforcement. If the latter is non-metallic the sleeve 8, ring 5, and supplementary ring are of soft metal. Specification 540,490 is referred to.

Abstract: 808,067. Dressing yarn. HOLT Ltd., T. and BUTTERWORTH, H. G. March 11, 1957 [March 24, 1956], No. 9242/56- Class 120(3) In a device for waxing yarns during winding by passing the yarn between a disc of wax carried on a spindle and a base rotatably mounting the spindle, rotation of the disc (by the yarn) relative to the speed of passage of the yarn is limited by means of an escapement movement which only permits of an intermittent rotation of the disc at a predetermined rate, thus encouraging uniform waxing of the yarn and wear on the disc: also, if a yarn breakage occurs, the pull of the yarn is insufficient to overcome the inertia of the device and the tendency of the yarn end to wrap around the spindle is eliminated. The device shown comprises a basal member 10 mounting a fixed spindle 11 on which a spindle 15 is rotatably mounted by means of a conical peg 17 and seating 11c and carries a table 18 for suporting a wax disc W and a star wheel 19 the teeth of which are intermittently and alternately engaged by teeth 21 of a pivotally mounted escapement lever 20 the mass of the unpivoted end of which provides the tension on the yarn.

Abstract: 1,203,411. Automatic steering control. BRITISH AIRCRAFT CORP. (OPERATING) Ltd. July 2, 1954 [April 2, 1953], No.9282/53. Heading G3R. A missile is guided to a target along a radio beam which is frequency modulated to provide steering signals for the missile. Error signals are developed corresponding to the misalignment between the receiver antenna axis and the direction of the target which are used for automatic correction of the beam. A second set of error signals are produced, corresponding to the iris alignment of the missile and the radio beam, which are subtracted from the first set to produce steering control signals, transmitted to the missile by frequency moderation of the radio beam. As shown, the reflections 10, are mounted in their axes parallel and movable in azimuth and elevation by motors 19, 18. A continuous beam transmission is sent out by antenna 12 from transmitter 20 and target echos are recorded as the four antenna horns 13, the phases of which are compared in 24 to give the misalignments correction signals supplied to 18, 19. The missile (not shown) transmits a unmodulated signal which is received at the beams 13, and separated from a target echo and phase compared in 25 to give the signal corresponding to the error between the reflector axis and the missile path. The difference between the errors is obtained and transmitted to the missile by frequency modulation of the transmission from 12 to control the steering in two perpendicular directions. For large missile displacements, an auxiliary reflector situated beside 10, 11 may be used.
