Title: Machine for the manufacture of bottles, flagons and other hollow glass objects
IPC: C03B9/22
Filed: 1932-01-18
Abstract: 378,768. Glass manufacture. SOC. ANON. D'ETUDES ET DE CONSTRUCTIONS D'APPAREILS MECANIQUES POUR LA VERRERIE, 3, Rue de Castellane, Paris. Jan. 18, 1932, No. 1468. Convention date, Jan. 31, 1931. [Class 56.] Blowing.-A glass-blowing machine of the kind that gathers by suction comprises two tables which carry the parison moulds and the finishing moulds, respectively, and are rotated step by step in unison with one another, and means for dipping the parison mould table during the pauses in its rotation in order to gather a charge of glass and to transfer a parison to a finishing mould. A device is also provided for circulating the glass in the forehearth from which it is gathered. The machine comprises a frame 2, Fig. 1, supporting columns 3, 4 on which the parison mould table 21 and the finishing mould table 17, respectively, are mounted. The column 3 slides vertically in the frame while the column 4 is fixed. A vertical driving-shaft 12, rotated continuously by a motor 5, is provided at its upper end with a crank 13 carrying a roller 14 which engages radial slots 15, Fig. 3, in a Geneva wheel 16 secured to the finishing mould table 17. Thus, for each revolution of the shaft 12, the mould table turns through part of a revolution and will then remain stationary. The movement of the table is communicated to the parison mould table 21 through similar gear wheels 20, 22. The column 3, on which the table 21 rotates, carries at its lower end a roller which rests on a cam 54 secured to the driving-shaft 12, and the cam is so shaped that it raises the table 21 during the period when the tables are rotating. Cam discs 28, 29 are rotatably mounted on the columns 3, 4, respectively, and the lower part of each cam is in the form of a toothed sector which gears with another sector 30 that is oscillated by the shaft 12 through gear wheels 35 and links 32. The parison moulds 41 and the finishing moulds 42 are hinged on their tables and are opened and closed at appropriate times by the oscillating cams 28, 29, respectively. The cams also raise and lower the mouth forming mandrels 45, and open and close the ring moulds 43. The supports for the ring moulds are clamped to vertical rods 44, and they may be adjusted to enable bottles of different heights to be made simultaneously. The parisons 55, Fig. 5, are slightly longer than the finished articles, and when they are transferred to the finishing moulds, the descent of the table 21 causes the bottom of the parison to be flattened by the mould bottoms. Delivering molten metal.-In order to present a clean surface of molten glass for successive gatherings, the glass is circulated in the forehearth 40, Fig. 1, by means of a paddle 37 secured to a vertical shaft 36 which is geared to the wheel 22.

Filed: 1965-01-13
Abstract: 1,109,381. Classifying transparencies. ILFORD Ltd. Jan.12, 1966 [Jan. 13, 1965; April 21, 1965; May 12, 1965], Nos. 1526/65, 16787/65 and 20076/65. Heading G2A. In an apparatus for producing prints from photographic transparencies there is provided means for classifying the transparencies according to their optical density ranges prior to printing so as to determine an exposure correction factor which varies the value the integral against time of image forming light has to reach before the exposure is terminated. A negative is scanned by a flying spot on a cathode-ray tube CRT, and light transmitted by the negative is directed on to the photo-multiplier PM1. A semi-reflecting mirror SM, a photo-multiplier PM2 and a constant input voltage control the intensity of the electron beam of the CRT, and hence of the light received by the negative. The collector current drawn by PM1 causes a voltage to develop across semi-conductor diodes LD, and the variations in this voltage are amplified in A. C. amplifiers VA1, VA2, connected to meters M1, M2. The deflection of the meter M1 indicates the optical density range D r  between the highest and lowest densities in the area of the transparency. The deflection of the meter M2 is proportional to a subject key factor S which is related to a quantity B, the quantity S being the proportional change in probability frequency through the range D r . Alternatively, or in addition to, finding the value of D r  for a transparency being classified, at least 10 area-elements of the transparency are scanned and the proportion B by which the number of such area-elements of density greater than the average density D z  of the transparency exceeds the number of such area elements of density below D z  is calculated. The value of D r  and/or the value of B are used to calculate a quantity A which in turn is used to calculate the correction factor which is a function of A and D z .

Abstract: 113,136. Wilson, W. G., and Metropolitan Carriage Wagon & Finance Co. Feb. 7, 1917. Calculating-apparatus.-Consists in mechanism for computing the angle of elevation or deflection of guns, the time of flight of projectiles and the fuse times, and comprises the combination of a number of substantially similar adjustable linkages, each connected to a lever from which it receives motion, and summation levers connecting both the first lever and the linkages to a part to be actuated, such as the sight of a gun or a pointer moving over a scale, the arrangement be ing that the effect of the first lever, which is moved according to the principal factors in the calculation, on the part to be actuated can be modified by the linkages in accordance with minor factors in the calculation. In Figs. 1 and 2 is shown apparatus for computing the tangent angle of elevation of gun-sights having given the range, angle of site, muzzle velocity, air density, and windage. The first lever d is actuated by a cam c and linkages in accordance with the range and the angle of site. The three similar linkages 1, 2, and 3, which introduce corrections for' muzzle velocity, windage and air density respectively, are connected to the lever d by links r, and the lever d and the linkages 1. 2, 3, are connected by links w, j, z, and summation levers x, y, k to a lever n which is arranged in conjunction with a scale or is connected to the sight. The first lever d is actuated by a range cam c through intermediate mechanism comprising a plate a, pivoted at b and having a follower engaging the cam c, and a link i connecting the lever d to a linkage f, g, h on the plate a. The linkage f, g, h can be adjusted by a lever m and link l for introducing the angle of site correction. Each linkage 1, 2 or 3 comprises a sector p, which is pivoted at q and connected to the sector d by a link r, and a quadrilateral jointed frame mounted on a fixed pivot t and connected to the lever x or y by a link w. The frame is connected to the sector p by a link v, Fig. 2, pivoted at u to the top link of the frame. The lower link 4 of the frame can be adjusted about the fixed pivot t to bring the pivot u into or out of coincidence with the pivot q of the sector p. When the pivots u, q coincide, as shown in Fig. 1, the linkage is in the normal position and rotation of the sector p does not produce deformation of the frame, but when the pivots are out of line rotation of the sector p produces deformation of the frame and consequent movement of the links w and finally of the lever o. Other corrections, such as for speed of target, may be similarly introduced.
