Title: Method and apparatus for glass sheet partitioning
IPC: C03B33/02
Filed: 1960-10-27
Abstract: <PICT:0972292/C1/1> The invention provides an apparatus for controlling the cutting of glass sheet such that the most economical use is made of each sheet in dividing it into glass of various quality grades. The sheet is inspected visually for flaws by an inspector who marks the position of each flaw on the glass sheet with a crayon of colour dependent on the severity of the flaw. Photo-electric means detect the presence and the position of each marking and cause perforating apparatus to punch tapes.  Each tape is perforated according to the position of the flaw markings indicative of flaws in excess of a certain severity.  A computer receives from the tapes information concerning the position and severity of the flaws, calculates the way in which it is best to cut the glass, controls the glass cutters, and marks the glass to indicate where further cuts should be made.  In the embodiment described, Fig. 1, the glass sheets, already marked in accordance with flaws of two severities, pass under a bank of photo-cells 20.  The level of the output of each photo-cell depends upon the colour of the mark passing beneath it, and, depending on whether this output lies above or below a certain value, a corresponding punch in one or both of two tape perforating assemblies 24 is operated, each cell controlling one punch in each assembly.  The tape records of the flaw locations supply information to a computer 16 which derives the cutting format. The computer controls the transverse cutter 12 and further selectively controls markers 564 which put marks on the transversely cut sheets to indicate the position at which the longitudinal cuts should be made. These marks may be in a medium which fluoresces under ultra-violet light.  The sheets so marked are fed, at right-angles to the direction of feed of the uncut sheets, to longitudinal cutters. Specifications 900,947, 906,983 and 972,291 are referred to.

Abstract: 380,063. Gunnery calculators. VICKERS-ARMSTRONG, Ltd. and WATSON, J. P., Vickers House, Broadway, Westminster. June 6, 1931, No. 16597. [Class 106 (i).] A device for determining fuze or other values such as time of flight or tangent elevation for gunnery purposes comprises an indicator or transmitter operated in accordance with the sum of the initial value of the function and the changes in such value due to movement of the target and the value of the dead time obtained from members adjustable in dependence on the values of the dead time and the rate of change in the value. In one form, as shown in the Figure, intended for determining fuze values a height-fuze chart A is rotated in accordance with the future angle of sight and a pointer A<1> carried by a screwed shaft A<2> is maintained on a given height curve. An initial fuze setting handle B is connected through a pair of differential gears C, D, to the shaft A<2> and to an indicator E<1> and transmitter E. To maintain the pointer A<1> on the given line the differential gear C is connected to a roller F<3> driven by a ball carriage F<1> co-operating with a constant speed disc F, the position of the carriage being controlled by a screwed spindle F<2>x from a hand-wheel F<2>. The spindle F<2x> also operates a screwed shaft G engaging in a nut on a radius bar G<1> which is thus adjusted in accordance with the rate of change of the fuze value. Mounted on the bar G<1> is a block G<2> connected to a pair of sliding members G<3>, G<4>, arranged at right-angles. The member G<3> is set from a milled head G<6> in accordance with the dead time and the consequent movement of the member G<4> is proportional to the product of the rate of change of the fuze value and dead time. This displacement is imparted to the differential gear D through a rack G<8> and gearing G<9>, G<10> so as to add the dead time fuze to the sum of the initial fuze and change of fuze. Various modifications of the apparatus are described in the Specification.
