Abstract: 1,156,066. Iron free powdered cristobalite; glass batch. PILKINGTON BROS. Ltd., P. H. GASKELL, and F. J. GROVE, 19 March, 1968 [23 March, 1967], No. 13817/67. Headings C1A and C1M. Quartz aggregate is converted to a powdered cristobalite form containing less than 5 p.p.m. of iron impurity by heating the quartz to a temperature of 1400-1700‹ C., pulverizing the cristobalite so formed, and acid leaching at an intermediate stage in the process to remove most of the iron impurity. A modification comprises heating the quartz through 575‹ C., one or more times, when the quartz shatters to smaller crystals, leached with acid and heated to 1400-1700‹ C. to form a friable cristobalite which is crushed. In a second method the quartz aggregate is heated to 1400-1700‹ C., and then acid leached and pulverized. In all cases pulverization is carried out in contact with materials which do not contaminate the cristobalite, e.g. rubber or plastics. The preferred acid contains 5% of hydrochloric acid and 1% of hydrofluoric acid. The final product may be used as a constituent of a glass making batch for producing glass with improved transmission characteristics.

Title: An improved rolling gear tester
Filed: 1959-04-23
Abstract: 869,771. Rolling gear testers. MAAG GEAR WHEEL & MACHINE CO. Ltd. April 23, 1959 [April 23, 1958], No. 13942/59. Class 106 (2). A rolling gear tester for testing intermeshing toothed gear-wheels 38, 39 has rolling rulers 14, 15 in slip-free connection with the spindles of the two gear-wheels 38, 39 through base discs 12, 13 having diameters independent of the wheels to be tested, and longitudinal movements of the two rulers 14, 15 relative to one another are effected by means of a control ruler 19 mounted on a slide 2 and angularly adjustable thereon in accordance with the transmission ratio of the gears to be tested. The gear-wheels 38, 39 are mounted on spindles 5, 6, the spindle 5 being journalled in the machine bed 1 and the spindle 6 in an adjustable carriage 7, the position of which is indicated on a scale 10. The spindles 5, 6 carry discs 12, 13 which roll without slipping on the rulers 14, 15, the non-slip arrangement is produced electromagnetically by means of an electric circuit through coils in the discs. The rulers 14, 15 are guided for transverse and longitudinal movement respectively on the slide 2 and on the bed 1, by rollers 11, 24. A slider block 17 is pivotally connected to the ruler 14 and slides in a longitudinal groove formed in the control ruler 19 which latter can be clamped to the slide 2 at any desired angle by a clamp 23, the angle being indicated on a scale 21. A record drum 28 is mounted on the slide 2 and is rotated, by means of a gear running on a fixed rack 32, when the slide 2 is moved longitudinally. Relative movement between the slide 2 and the ruler 15 is recorded on the drum 28 by an arm 27 actuated by a lever 26 pivoted on the slide and with one end in a recess 25 in the ruler 15. In use, the control ruler 19 is adjusted to an angle determined by the sizes of the discs 12, 13 and the numbers of teeth on the gear-wheels 38, 39. The ruler 15 is then biased to one side or the other by one of two springs 34, 35, depending on which flank of the wheels it is desired to test. The handle 40, which may be replaced by an hydraulic or electric motor, is turned to move the slide 2, the ruler 14 moving transversely of the bed 1, and so driving the gearwheels 38, 39 and the ruler 15. If the ruler 19 is correctly adjusted and the teeth of the gears are also correct, there should be no relative movement between the slide 2 and the ruler 15, but any inaccuracies which may arise are recorded on the drum 28. If the control ruler 19 is adjusted in the opposite direction, an internallytoothed gear-wheel may be tested. A modification is also described in which bevel and hypoid gears can be tested. The electromagnetic couplings may be replaced by conventional steel bands.

Patent GB-456753-A (GB)
Title: Improvements relating to devices for grading and testing eggs
IPC: G01G1/28
Filed: 1935-05-14
Abstract: 456,753. Electric signalling systems. SALMON, J. T., Blackmore Paddocks, Shamley Green, Guildford, Surrey. May 14, 1935, Nos. 14138 /35 and 12356 /36. [Class 40 (i)] [See also Groups XVIII and VI] A device for grading eggs in accordance with their weights comprises a balance lever or frame arranged to engage and lift a number of weights in succession as eggs of increasing weight are placed upon the balance, and the balance lever or frame carries a circuit-controlling member which, as each weight is lifted, closes one of a number of electric circuits so as to actuate a number of electric indicators each responsive to a weight lying within a predetermined range. The eggs are placed on four bevelled rollers 20 mounted on the balance lever pivoted on a ballbearing fulcrum 10. A transverse bar 30 on the balance lever. is arranged to raise successively, a series of light pivoted arms or springy tongues 31 each loaded with a weight 33. The free ends of the tongues are thus removed successively from electrical contact with fixed springs 35 arranged respectively in the circuits of corresponding indicator lamps 36. When an egg is placed on the bevelled rollers the crossbar 30 (which is included in the electric circuits) rises to an extent dependent on the weight of the egg and completes a circuit through one of the loaded tongues 31 and the corresponding fixed spring 35 with the result that the appropriate lamp is illuminated to indicate the grade of the egg. In order to avoid uncertainty by all the lamps being extinguished at the limiting positions between the grades, the spring tongues 31 and the fixed springs 35 are arranged so that just before the lamp of one grade is extinguished the lamp of the next grade is illuminated. The case opening through which the egg support projects may be closed by a flap 48 which, in the closed position, depresses the balance sufficiently to lock the parts against injury in transit. When in the open position, the flap is retained by a catch which acts to close a contact in the main circuit from the transformer or battery. A dashpot 8 damps vibration.
