Title: Method and apparatus for manufacturing glass beads
IPC: C03B19/10
Filed: 1964-11-17
Abstract: <PICT:1066768/C1/1> In a method of producing glass beads a stream 16 of conditioned molten glass is flowed into a stream of high velocity gas substantially transverse to the path of the molten glass, thus dispersing the glass stream and causing it to be carried along by the gas stream, and raw gas is fed into the stream of high velocity gas in which it is burned to thereby maintain the latter at a temperature sufficient to maintain the glass viscosity below 500 poises, so that the dispersed glass spheralizes and forms glass beads.  The glass stream 16 may be conditioned by passing an electric current therethrough, by having an electrically conducting orifice 14 in a glass melting tank connected to an electrical supply source 20 in turn connected to an electrode 18 which arcs across to the stream 16. The high velocity gas stream is formed by expelling the combusted products of a gas from the orifice 26 of a burner 24 at velocities in excess of 40 f.p.s., preferably about 250 ft./sec. By feeding raw gas at a low velocity from a pipe 34 into the high velocity stream, wherein it is burned, the required temperature is maintained. The formed beads are collected in a tank 40 filled with a suitable fluid medium 42, e.g. water and oils, wherein the beads are cooled, and may be tempered.

Abstract: 1,048,400. Endless conveyers. MIDLAND COUNTIES DAIRY Ltd. Dec. 18, 1964 [Dec. 10, 1963], No. 48635/63, Heading B8A. A mass of thirty cases containing empty milk bottles may be placed on case handling apparatus by a fork-lift truck, the mass then being stripped into groups containing two stacks of five cases which are passed into a dairy. After washing, filling and recasing the bottles, the eases are re-assembled into a mass of thirty ready for lifting by fork-lift truck. Case-stripper.-The mass of cases 20-25 are placed on continuously driven endless conveyer 15 provided with guide rails 26, 27 which are interrupted at a gate station 29 comprising gates 30, 31, linked by a tie bar 34. An operator waits until the stacks 20, 21 have passed the gate station 29, then operates a pneumatic cylinder 35 to actuate the gate and prevent the remaining stacks from passing the station. A stop 36 is moved to its retracted position and the stacks 20, 21 operate valves 47 which cause operation of rams 40, 41. These push the two stacks off the conveyer 15 on to a transfer station platform 53 which is then lowered below chains 49 of a second conveyer 48 and the stacks are moved down the second conveyer. When the rams reach the limit of their travel they operate a valve 64 to cause the gates 30, 31 to open and the stop 36 to be raised. The next row of two stacks 22, 23 then passes through the gate and up to the stop 36. The gate is then closed and the stop lowered as a result of a signal sent by a valve 61 when passed by the stack 20 on the conveyer 48. The stacks 22, 23 then pass to the transfer station 52 and the stacks 24, 25 are held at the gate station 29. The cycle continues so long as there are stacks of cases on the first conveyer 15. The refilled cases are formed into stacks five high by a known masser 13, Fig. 1 (not shown) and then pass to a masser 14. Masser 14 comprises a first conveyer 65, a second conveyer 66, a gate station 65a and a transfer station 84. When two stacks 81, 82 move down the conveyer 65 in the direction " C " the following stack 83 is halted at a stop 76 by operation of a gate 74. When the two stacks 81, 82 reach the transfer station 84 they are pushed on to a dead plate 99 at the start of the second conveyer 66 by a ram 86. A second group of stacks is then allowed to move from the gate station 65a to the transfer station whence it is moved on to the dead plate 99 by the ram 86. The first group is thus pushed on to the conveyer 66 and travels in the direction " D " until it reaches retractable stops 105. When three groups of stacks have been assembled on the conveyer 66, the operator drops the stops 105 and the mass of stacks moves on for removal by fork-lift truck.

Abstract: 486,841. Calculating - apparatus. GARDNER CO. Nov. 24, 1937, No. 32367. Convention date, Dec. 4, 1936. [Class 106 (i)] In a calculating-machine having accumulator wheels equipped with tens transfer, mechanism of the crawl type,. overdraft indicating segments 506 are fixed on the accumulator wheels, a sensing arm 510 co-operating with each segment to indicate an overdraft, and plus indicating segments 505 are also fixed on the accumulator wheels, a sensing arm 508 cooperating with each plus segment to disable the overdraft sensing arm of the next adjacent lower order accumulator wheel. Arms 510 are forked to engage segments 506 and, when rocked, they operate one of two bell-crank levers 518 and 519 which carry on their upper end positive and negative signs which are shown at the bottom of the keyboard of the instrument. When arm 508 is raised by a tooth thereon moving on to the solid portion of segment 505, arm 510 is moved away from its segment 506 and, as each arm 508 carries a web overlapping the arm of the adjacent lower order wheel, all lower order arms 510 are also disengaged. This ensures that changes in the lower wheels do not affect the indication of the sign of the whole total in the machine. The transfer arrangement is substantially in agreement with that of Specification 272,569, [Class 106 (i)], and comprises epicyclic gearing counections 470 between the successive wheels of the accumulator. As applied to an adding machine, the invention is shown as co-operating with the mechanism disclosed in Specifications 389,630 and 406,152. The apparatus comprises a lever 610 connected to a type bar 611, a rack driving the register 403, and a differential stop bar 615 co-operating with digit keys 215. A total is taken by releasing the differential. stop bars 615 and allowing them to rotate the accumulator subtractively. This will set the total on the type bars and printing is then effected. True negative totals are printed by arrangements as disclosed in. Specification 389,630. The apparatus can also be used in connection with calculating-machines as described in connection with Specification 334,045, [Class 106 (i)], in which division is effected by repeated subtraction controlled by the positive or negative registration of the accumulator upon which the dividend is registered. In this machine amounts set up in differential actuators of any preferred type are transmitted through intermediate gears 477. 480, and 482 to the numeral wheels 473. Compensation for fractional tens transfer movement is obtained by rotating the shaft of gear 482 round shaft 481. under the control of a lug 484 bearing on a cam 485 on the numeral wheel 473. Arms 544 and 545 in this construction correspond with arms 508 and 510 in Fig. 1.
