Title: Improved method of and apparatus for feeding charges of molten glass
IPC: C03B7/08
Filed: 1923-03-19
Abstract: 195,376. Hartford-Empire Co., (Assignees of Peiler, K. E.). March 25, 1922, [Convention date]. Delivering molten metal.-Relates to an automatic feeding-device and consists in providing means whereby the feeder delivers changes of molten glass of different predetermined weights in regular succession, so that articles of different weights may be made with one feeder. The invention is particularly applicable to the type of feeder in which glass 10, Fig. 1, contained in a fore hearth 11 discharges through an outlet 12 and is cut off into charges by shears 36, the flow of metal being arrested and the cut end of the glass reheated by a gas flame burning under pressure in a cup 14, which is moved into and out of the operative position. The variation in the weight of the charges delivered is obtained by varying the time during which the burner 14 is closely adjacent to the outlet 12. Construction and operation. The arm 15 carrying the cup 14 is secured to a vertical rod 16 which is mounted loosely in a standard 19 and is reciprocated bv a rocking-lever 20. A pin 27 fixed to the rod 16 engages a slot 26 in the standard 19, the slot being so shaped as to swing the cup out of the way of the falling charge. The rod 16 also operates a valve that controls the supply of gas to the burner 14 and cuts off the main supply when the cup is lowered into inoperative position but permits a pilot light to be fed by a bye pass. The lever 20 is rocked by cams on a shaft 52 and the shear blades 36 are also operated by a cam on the shaft 52. The lever 20 is actuated by a number of cams, the number corresponding to the different sizes of charges that are to be delivered. Each arm comprises two members 51, 53, Fig. 6, the member 51 being fast and the member 53 being loose on the shaft 52. An arm 47, 48, or 49, Fig. 4, forming part of the lever 20 rests on each cam. The loose member 53 is formed integral with a bevel gear 55 which is driven through a small bevel pinion 56 from another bevel wheel 57 loose on the shaft 52. The gears 57 are rotated in the opposite direction to the shaft 52 and at an equal speed, so that the two members 51, 53 of the cams rotate in unison. The small bevels 56 are mounted on segmental gears 61 that can be rotated about the shaft 52 by turning handwheels 64. Thus by means of these handwheels, the two sections 51, 53 can be moved relatively to one another and the shape of the cam can be altered. The shape of the cam regulates the period during which the cup 14 is close to the outlet 12 and thus regulates the amount of glass which passes through the outlet between successive operations of the shear blades. The space between the top of the cup 14 and the outlet may be adjusted to regulate the pressure of the gas flame on the stub of glass. The charges may be guided into the moulds by means of a shoot 76 as described in Specification 104,605.

Abstract: 216,495. British Thomson-Houston Co., Ltd. (Assignees of Alexanderson, E. F. W.). May 22, 1923, [Convention date]. Vapour and vacuum apparatus, arrangements of; phase, changing.-In order to obtain alternating currents of sinusoidal wave form from direct current mains, the current is passed through a group of electron discharge valves connected to primaries of three-phase transformers, and the grids or other elements determining the conductivity of the valves are subjected to potential waves of rectangular form obtained from an auxiliary group of high-potential low-power valves. In the thermionic valve arrangement shown in Fig. 1, twelve valves 1 - - 12 feed two double star transformer primaries 15, 21 having secondaries 31, 32 so disposed as to recombine the twelve-phase impulses into three phases, and to eliminate harmonics in outgoing distribution lines 33, 34, 35. The auxiliary valves 42 - - 53 are fed from the same direct current mains and have their grids subjected to rectangular waves from adjustable tappings of a ring winding 59, a cross-ring winding 61, and a battery 63. A rotary converter 66 determines the frequency in the alternating current distribution mains. In a modified arrangement the auxiliary grid potentials are obtained from a common transformer having an extended delta primary and a starconnected secondary. In a further modification mercury vapour rectifiers are arranged to furnish rectangular potential waves for the grids of the valves 1 - - 12.

The image of the reference object is passed via an inverter to a store. The camera now scans the sample object and the image of the sample is displayed in a first colour, e.g. green. The sample image is also passed to a comparator where it is compared (by summation) with the inverted reference image to provide a difference image signal corresponding to the shape differences. The difference signal is displayed in a second colour, e.g. red. To prevent non-significant imbalance of the sample and reference image signals from causing display of a difference, the difference signal is inhibited when it lies below a certain amplitude.

Filed: 1942-06-20
Abstract: 551,397. Lathes; gauging-devices. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SMITH, S. R. June 20, 1942, No. 8489. [Class 83 (iii)] A gauging device which may be embodied in an attachment to a lathe or like machine-tool, particularly for forming a number of shouldered portions on a cylindrical work-piece, comprises a member carrying a number of adjustable stoprods which can selectively engage a stop on the tool carrier, the member being coupled by magnifying linkage to a visual indicator which shows the precise position of the tool. The lathe comprises a saddle 10 fitted with a cross-slide 11 which carries a longitudinal tool-slide 14. A stop 16 secured to the tool-slide coacts with one of a series of ten adjustable stop-rods 18 arranged round a barrel 19. When the end of a traversing cut is approached the barrel is thus caused to move axially with the tool and causes a stem 28 to operate a magnifying lever 31 which actuates a dial 19a to indicate the precise final position of the tool. The latter may then be moved transversely by the cross slide to machine the face of a shoulder. A second gauging-device 38 of similar multiple stop-rod construction is mounted on the saddle, the rods coacting with a stop 37 on the cross slide to adjust the transverse tool position between successive longitudinal tool movements so that a number of stepped portions of predetermined diameter may be cut on the work by successive indexing movements of the stop barrels. The barrel 19 is supported at one end by pins 24, 25 in an indexing ring 26 moving in a bush 27. The barrel-shaft 23 is supported at its other end in a V-slot in a bracket for quick detachability. Locking of the barrel is effected by a ball which is carried by a spring 33 secured to the index ring and which coacts with spaced holes in an index plate 32 detachably mounted on a bracket 21. The plate is only perforated with the holes required for a particular series of dimensions, thus automatically selecting the required stop rods. The ten positions of the index ring may be indicated by letters and the ten positions on the device 38 by numerals so that operating instructions may be given by a series of index letters and numerals. The exact position of the shoulders on the work may be set by the micrometer head 29 which moves the pin 25 and the barrel without altering the pre-set relation of the stop rods.
