Title: Improvements in or relating to the manufacture of reinforced glass
IPC: C03B13/12
Filed: 1963-10-07
Abstract: <PICT:1048248/C1/1> <PICT:1048248/C1/2> <PICT:1048248/C1/3> In the production of metal reinforced glass ribbon, in which a guiding member controls the position of the reinforcement relative to the upper and lower rolls between which the molten glass is passed to form the ribbon, the guiding member is divided in the direction of length of the upper roll into a plurality of segments, each segment being free to move relatively to adjacent segments, means being provided responsive to radial movements of the corresponding portion of the upper roll for controlling the position of each guiding segment thereby to maintain the metal reinforcement at a constant distance from the upper surface of the ribbon. As shown in Fig. 1, molten glass 1 is passed between rolls 2, 3 to form a ribbon 4 supported on an apron 5 and rollers 6 and a metal reinforcement 7 is fed from a reel 8 over a guide plate 9 which is divided into a number of segments, each segment supported over the roll 2 by ribs 10 dimensioned to fit the roll diameter. The desired depth of the reinforcement 7 is adjusted by a hand wheel 11 operating bevel wheels 15, 14 and gear-wheel 13 engaging toothed section 12 on the guide plate 9, each segment being separately adjustable.  In a modification, the guide plates are carried by collars over roll 2, each segment having an adjusting spindle secured between brackets on the collar.  In a further modification, the lower edges of the plates 9 are joined only to the plate at each end so as to form narrow cross-bars which may be immersed in the molten glass.  The lower parts of the plates may also be interchangeable, particularly to be used when the reinforcement is in the form of individual wires and the plates have corresponding grooves.  In Fig. 7, the guide member is in the form of roller segments 36a, 36b . . . carried on arms, as 38c, on collars 37a, 37b . . . mounted on roll 2 and adjustable as in Fig. 1.  In a modification, each roller segment is positively rotated from roll 2 by an interposed roller.  As shown in Fig. 5, the guide plate 34, in segments, is not supported directly on the roll 2 but is moved therewith by mechanical contacts comprising a springpressed follower 26 on arm 27 centrally pivoted at 28 and linked at its opposite end 56 to an arm 30 centrally pivoted at 31 on which the plate 34 is mounted.  The pivot 31 is adjustable by hand wheel 32 for positioning the wire reinforcement 7 initially, with the plate 34 movable vertically on a fixed member 35.  The movement of roll 2 can also be transmitted to the guide member by electrical or hydraulic means.  The segments may be loosely interconnected by tongue and groove, to allow for expansion and different movements thereof.

Abstract: 1,071,810. Measuring dynamic unbalance electrically. LOSENHAUSENWERK DœSSELDORFER MASCHINENBAU A.G. Oct. 5, 1964, No. 40526/64. Heading G1N. The dynamic unbalance of a rotor as measured at two bearing planes by e.g. Piezo-electric transducers is converted to components in two balancing planes by means of exponentially wound potentiometers, set up in accordance with the distances between the various planes using log scaled dials, whereby the required multiplication and division is effected by addition and subtraction of voltages. Using the standard designations shown in Fig. 1, a voltage U I  representing the unbalance P I  is fed to an exponentially-wound potentiometer 15 (Fig. 2) whose slider 16 is driven through an angle representing the logarithm of distance a by a log-calibrated knob 1 acting through a clutch 13, to give an output voltage representing P 1 a. Similarly, a voltage U 11  representing unbalance P II  is fed across a second exponentially wound potentiometer 35 whose slider is driven through an angle representing the logarithm of distance c by knob 3 and clutch 33, to give an output voltage representing P 11 c. A third spring- loaded knob 2 is rotated through an angle representing the log of distance b and is coupled to both potentiometer shafts, whereby each output voltage is divided by b, giving U 1 a/b and -U 11 c/b respectively. These voltages are added to U 1  or -U 11  to give signals representing P 1  or -P 2  respectively.
