Title: Improvements in and relating to methods of and apparatus for working quartz
IPC: C03B23/047
Filed: 1924-09-12
Abstract: 222,119. British Thomson-Houston Co., Ltd., (Assignees of Berry, E. R., and Devers, P. K.). Sept. 20, 1923, [Convention date]. Forming silica-glass articles. - A method of forming tubing of fused silica consists in heating the end of a rod of silica until it is plastic, mechanically perforating a portion of the plastic rod along its longitudinal axis, and then applying gaseous pressure internally to expand the rod to tubular form. A machine for carrying out the process comprises a number of burners 13 mounted on an horizontal disc 16 which is rotated in contact with' a table 9 by means of a motor 11. The flames from the burners form a heating zone into which a. rod 12 of quartz is fed. A vertical tube 54 is secured to the machine base 8, and another tube 53 slides within this tube and can be moved up and down by a handle 75. The tube 53 is closed at its base and is connected by a flexible pipe 44 with a source of air pressure. A rod 46 passing through the tube 53 carries at its upper end a spur or forming-tool 45 which can be moved to and from the heating zone by means of a lever 47. At the commencement of operations, the end of the quartz rod 12 is heated until it is plastic and is fused on to a tube 42 of quartz which surrounds the spur 45 and passes down within the tube 53. The spur 45 is then forced upwards into the plastic end of the quartz rod to perforate it, and air admitted to the tube 53 passes into the cavity formed by the spur and expands the end of the rod into a tube. The size and shape of the quartz tube is controlled by a mould 56 consisting of two sections pivoted to the top of the tube 54 and opened and closed by a lever 68. When a length of the tube is thus formed, the mould is opened and the quartz rod and tube are lowered by means of the handle 75. The succeeding section of the rod is then heated and expanded in the mould as before.

Abstract: 1493306 Estimating best signal in a multichannel redundant system SIEMENS AG 20 May 1975 [22 May 1974] 21642/75 Heading G1U In a multi-channel redundant system, an estimate of the true signal is obtained from a plurality of transmitted signals by rejecting both the largest and the smallest and forming the arithmetic average of the remaining signals. Of four redundant signals A, B, C, D, Fig. 1, the largest and the smallest are selected by units 1 and 2 respectively and applied, via inverters 4, 5, in opposition with the four signals A, B, C, D, to a summing amplifier 3, whereby the output 15 is proportional to the desired estimate. The largest and smallest selecting circuits 1, 2 both include LED's to indicate the channels on which these signals occur, and further LED's 10, 11 indicate when the output signal 15 differs from the largest and smallest signals by more than pre-set thesholds U s1 , U s2 . Minimum signal selector. Four signals 2a, 2b, 2c, 2d, Fig. 2, of which the minimum is to be selected and passed out 2e, are applied, via summing modes, to inverting amplifiers 16a, 16b, 16c, 16d, and  thence, via a decoupling amplifier 18, to the output, there being feed back from the output 2e, as shown, which results in every amplifier 16a, 16b, 16c, 16d, except that receiving the smallest input signal, limiting and back-biasing its associated diode. The amplifier outputs are also compared with a pre-set threshold level U s3  to recognise that one which is not saturated and thence indicate 21a, 21b, 21c, 21d, the channel carrying the smallest signal.

Abstract: 605,721. Electric follow-up systems. YARDENY, M. N. Aug. 24, 1945, No. 21798. [Class 40 (i)] In a follow-up system employing coarse and fine follow-up switches, means are provided for disconnecting the fine follow-up switch while the coarse switch is controlling the follow-up motor. Fig. 1 shows an arrangement in which coarse and fine follow-up switches II and I actuate split field series motor 2 when their " stators " 20 and 10 are displaced with respect to their rotor arms 21 and 11 by means of friction drive knobs 38<SP>x</SP> and 48<SP>x</SP>. Initially, the motor takes current through relay 72 and follow-up switch II, the former isolating switch I, until switch II has been driven to approximate correspondence, when relay 72 is de-energized and fine switch I takes over control of the motor. Resistors 4 and 5 are provided to reduce the motor speed when switch I controls it and to prevent the motor being stopped by the equal energization of field windings 6 and 7 which would otherwise occur each time rotor 11 bridged gap 19<SP>1</SP> when switch II was in control. Selectors I<SP>1</SP> and II<SP>1</SP> may be utilized by closing switch A<SP>1</SP> instead of switch A. Pairs of relays may be interposed between the switches and the motor, as in Fig. 2 (not shown), or, as in Fig. 3 (not shown), a single pair of relays may be used to control a shunt motor. Fig. 4 shows an alternative linear follow-up switch in which the motor moves rod 79 carrying contact segments 86, 87, co-operating with adjustable and fixed contacts 81<SP>x</SP> and 24, 25. The arrangement of Fig. 2 may be further modified, as in Fig. 5 (not shown), by using relays having double armatures, the second pair being used instead of relay 72 in the case of the pair associated with switch II, and for cumulatively energizing the other motor field winding in the case of those associated with switch I. Fig. 6 shows an arrangement for use when a number of pairs of preset switches are used, the relay 172 replacing relay 72 and being provided with contacts 162 in the circuit of switch II, the movement being started by depressing a push-button 170 bridging the contacts. The Figure also shows a modified switch in which additional gaps 26<SP>x</SP> and 27<SP>x</SP> are made in the contact segments.
