Title: Improvements in or relating to apparatus for drawing sheet glass
IPC: C03B15/18
Filed: 1927-05-05
Abstract: 271,444. Hermann, H. May 20, 1926, [Convention date]. Drawing. - Relates to drawing-apparatus of the kind in which the glass is drawn vertically upwards in a flat sheet by pairs of opposed rollers, and consists in providing means for enabling the rollers to adjust themselves to variations in the thickness of the sheet and to any warping or twisting of the sheet which may occur. In the construction shown in Fig. 5, a sheet B is drawn vertically upwards from a pot W by means of pairs of rollers a arranged vertically above one another. Each roller a may be divided into a number of annular sections a<1>, and the whole of the sections are driven by an internal driving-shaft b, Fig 1, on which they rest. The weight of the sections forces them into contact with those of the associated roller, but the arrangement enables the sections to move apart and adapt themselves to irregularities in the thickness of the sheet B which is gripped between the rollers. The rollers may be solid, and in this case they are so mounted that they can swing about the axes of the driving-shafts b, as shown in Fig. 2. They are held in contact with one another, and with the sheet B, by counterweights n or by springs. Each pair of rollers is mounted on a frame f, Figs. 5 and 6, carried by a wheeled truck g. The truck can be moved transversely to the plane of the sheet B and the frame f can be turned about a vertical axis, thus enabling the rollers to be kept in contact with the whole width of the sheet should it become warped. The pairs of rollers are driven by flexible or articulated shafts d, and the speed of the rollers is arranged to increase slightly from the lowest to the highest.

Title: Improvements in synchronizing signalling systems
IPC: H04N1/36
Filed: 1937-04-30
Abstract: 496,485. Electric synchronous movements ; change - speed epicyclic gearing. FINCH, W. G. H. April 30, 1937, No. 12428. Convention date, May 11, 1936. [Class 40 (iii)] [Also in Group XXIV] Means for driving a member such as a picture-drum 49 in a telepicture receiver, in synchronism with the transmitter, under the control of synchronizing signals originating at the transmitter, comprises one or more planetary worms 96, Figs. 4 and 6, supported in a planet-carrier 93, fast to a driving-shaft 56, ane having irreversible engagement with a worm-wheel 97, fast to a driven shaft 60, carrying the picture-drum 49. Normally the gearing rotates solid, giving a one-to-one drive, but when a bevel-wheel 61, normally rotating with the gearing, is held fast by a detent 63, bevel pinions 101, fast to the planetary worm-shafts 95, roll on its surface and cause rotation of the worms on their own axes. According to the ratio selected fcr the worm and bevel gearing the resulting rotation of the driven shaft 60 is reduced to a low forward speed, to zero, or to a reversed drive. In the modification shown in Fig. 8, the planetary worms 116 are connected by spur-gear pairs 124 to a parallel diametral shaft 122, bevel-geared at 120 to a control shaft 110, loosely mounted inside the driving sleeve 56<1>, and carrying externally a disc adapted to be held in the same manner as the bevel-wheel 61 in Figs. 4 and 6. Such holding is effected each time a notch 76, Fig. 6, on the bevel-wheel 61 comes opposite the upwardly spring-pressed detent 63, unless or until the detent is withdrawn from the periphery of the wheel by energization of an electromagnet 62. An oppositely acting detent 103, permanently loaded against the wheel by a spring 104, engages another notch 105 in the wheel and prevents rebound of the latter against the detent 63. As applied to copying telegraphy, the shaft 60, Fig. 2, carries the drum 49 and once each revolution opens a contact 70, 71 to remove a short circuit from relay 75. The synchronizing signal sent at the end of each line actuates relay 75 to actuate relay 62 to withdraw the catch 63 from the notch 76 in plate 61, so that plate 61 is free to rotate and shaft 60 rotates for a further revolution, being stopped again when catch 63 falls into notch 76. British Specification 492,379 (as accepted and as open to inspection under Sect. 91), and U.S.A. Specifications 1,985,654, 2,047,863, 2,051,511, and 2,069,061 are referred to.'
