Abstract: 980,213. Measuring acceleration electrically. ELECTRA SCIENTIFIC CORPORATION. Nov. 12, 1962 [May 15, 1962], No. 42584/62. Heading G1N. The cross sensitivity of an accelerometer is minimised by hemispherically shaping the base 12 of the transducer 10, comprising a crystal elements 15,16 respectively bonded to a central support 11 and masses 17 18 and making it complimentary to the base 21 of a casing 19 so that by means of four ball ended adjusting screws 32 engaging a transducer top plate 25 and passing through threaded holes 31 in a cover 28, the transducer may be orientated with respect to the casing 19 to align the transducer and casing electromechanical and principal mechanical axes. The casing 19 is affixed to a table 33 (Fig. 2) by an integral stud 23 and is vibrated in a direction normal to the casing principal mechanical axis 36, the resulting accelerometer output being measured across lead wires 11<SP>1</SP>. The screws 32 in the cover 28 itself temporarily held to the casing 19 by screws 30, are adjusted until the principal mechanical axis of the transducer is tilted with respect to the case and the accelerometer output is a minimum thus indicating where the transducer electromechanical and the casing principal mechanical axes are aligned in one plane. The casing is then turned through 90 degrees, the table vibrated, and the transducer again orientated by the screws 32 until the output is a minimum. With the screws 32 in position, the transducer base 12 is bonded to the casing, after which the cover 28 is removed and a permanent closure 38 (Fig. 7) incorporating a co-axial connector 39, 41-45 is bonded into position so as to hermetically seal the casing.

Patent GB-921743-A (GB)
Title: Improvements in photometric measurements
Inventor: AKHTAR MOHD
IPC: G01J1/36
Filed: 1960-12-12
Abstract: 921,743. Photometric measurements. COURTAULDS Ltd. Dec. 11, 1961 [Dec. 12, 1960], No. 42653/60. Class 40 (3). The invention relates to a beam-chopping device for use in photometric apparatus in which two light beams are compared, and comprises a beam chopper 5 connected to the shaft of a two-pole polarized rotor synchronous motor 2. With a beam chopper driven by such a motor it is possible to know continuously the precise angular position of the chopper. The device is used as shown in photometric apparatus in which light passing through a liquid reference 13 is compared with light passing through a sample solution 16, to determine a characteristic of the solution such as its concentration or constitution. A beam of light from a source 17 is directed to fall on the chopper which comprises a circular disc (Fig. II, not shown), one semi-circular segment of which has a mirror surface and the other is transparent, so that the beam is directed alternatively through the reference 13 and the sample 16. The beam after passing through the reference 15 is reflected by a mirror 14 and then passes through a light attenuator such as an optical wedge 24 on to a photo-electric cell 19 the output of which is passed through a condenser 20 to an amplifier 21, the amplified output being passed to the control winding 22 of a servomotor 23 which adjusts the position of the attenuator 24 through a gearing mechanism 25. When the beam has passed through the sample 16 it is reflected by a mirror 18 directly on to the photo-electric cell 19. The servomotor 23 adjusts the attenuator 24 so that the amount of light which falls on the photo-electric cell 19 after transmission through the reference 13 is the same as that which falls on the cell 19 after transmission through the sample, the position of the servomotor shaft being indicated by a recording voltmeter 29 fed from a potentiometer 27 the wiper arm of which is connected to the shaft of the servomotor. In order to facilitate initial setting up of the equipment the beam chopper motor 2 is adjustably mounted so that the angular position of its shaft relative to the chopper may be altered. This is of importance since in order that the servomotor 23 will position the attenuator correctly the waveform from the cell 19 to the control winding 22 must be substantially in phase or 180 degrees out of phase with the voltage applied to a condenser between a reference winding 26 of the servomotor and the supply to the motor 2. Specifications 677,942 and 778,505 are referred to.

Abstract: 992,142. Rectifying. RADIO CORPORATION OF AMERICA. Nov. 19, 1962 [Nov. 20, 1961], No. 43715/62. Heading H2F. The Specification relates to circuits for generating high direct voltages for the electron guns of colour television receivers from the line scan flyback pulses. According to the invention two rectifiers 108, 124 supplied from windings 90, 92 on the line scan transformer 78 are connected as shown to the cathodes of one electron gun and to the final anodes of both. The other cathode is connected to the local earth potential. Fig. 2 is a simplified form of Fig. 1 (not shown) which is a block diagram of the television receiver circuit, with detail of the deflection circuit and the supplies to the electron guns. Receivers of the type in question use a television tube with three electron guns whose cathodes are at different voltages. The red gun has the smallest voltage, the blue gun the largest voltage and the green gun a voltage in between. Winding 90 is the primary of the transformer 78 to which the deflection windings are directly connected. The voltage developed across this winding is rectified by the diode 108, smoothed by the capacitor 114 and applied to the cathode of the red electron gun. The voltage developed across the secondary winding 92 is rectified at 124, smoothed at 128, and fed to the final anodes 62, 64, 68 of all the guns and to the screen of the tube. The voltage across the tertiary winding 94 is rectified at 136, smoothed at 144, and connected with the opposite polarity to the cathode of the blue electron gun 28. Potentiometers, not shown, are connected across each of the output voltages thus obtained to provide focus voltages. In a modification (Fig. 3, not shown) only two windings are used on the transformer so as to obtain better coupling. The Specification discusses the voltage regulation between the three outputs.
