Title: Improvements relating to thermo-electric generators
Inventor: FRASER MURDO
IPC: H01L37/00
Filed: 1961-12-11
Abstract: 962,747. Thermoelectric signal generators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 7, 1962 [Dec.11, 1961], No.44262/61. Heading G1A. [Also in Division H1] A thermo-electric signal generator comprises, Fig. 1, a body of thermo-electric material 1 having electrical terminal members 2 secured to two spaced apart portions thereof, a heat source 3 adapted to produce local heating of the region of the body between the two portions, and means to produce relative movement between the heat source and the body along a line joining the spaced apart portions. The invention is based on the Thomson or Kelvin effect, viz. that an e.m.f. is generated across the ends of a length of thermo-electric material when an area intermediate the ends is heated, the value of the e.m.f. increasing as the heated area approaches an end, and having a sign depending on which end is approached. The embodiment of Fig. 1 is a sinusoidal signal generator wherein the electric filament heat source 3 and a lens system 15, focusing the heat radiation on the semiconductor thermoelectric Body 1, are carried on a platform 5, grooved to slide in a hole in table 10 with simple harmonic motion under the action of motor 20, disc 18 and rod 17. The output signal is displayed on means 21. Another signal generator according to the invention comprises, Fig. 2, a ring 41 of semi-conductor material with terminals 42 and a heat source 43 continually rotating inside the ring, such that the sawtooth waveform of Fig. 3 is produced across the two terminals. Alternatively Fig. 4 (not shown) the upper half of the ring 41 may be of one type of conductivity (say N) and the lower half may be of the opposite type of conductivity (say P), the two halves being electrically and thermally joined, to produce a sawtooth output waveform Fig. 5 having negative going and positive going portions of equal slope. Alternatively the waveform of Fig. 5 may be produced using two sections 81A and 81B, Fig. 6 of the same type of conductivity, but with the two sections connected in opposition by wire 82. The invention may be incorporated in a system Fig. 8 whereby the position of a movable carriage 105 of a machine tool is controlled. A plate of thermoelectric material 101 is mounted on a stationary part of the machine tool whilst the heat source 104 and associated focusing means are mounted on the movable carriage. The datum position of the movable carriage is set such that the heat from source 104 is directed on to the middle of the plate 101 such that no e.m.f. is generated across the terminals 102. Movement of the carriage from the datum position produces an e.m.f. across the terminals of a sign dependent on the direction of movement, which e. m. f. is applied via an amplifier to a motor 108, controlling, via gears 110 and worm shaft 109, the position of the movable carriage. The thus produced movement will be such as to return the carriage to the datum position. .The semi-conductor material may be lead telluride.

At the bottom of the tank heaters 8, 9 are positioned which may be used to establish a required temperature gradient. In operation, a slightly tapered bore hole former of about twelve inches diameter is placed vertically in the tank and packed around by water saturated gravel which is then frozen for 3-4 days to simulate permafrost. When the permafrost has been completed the former is removed and replaced by a six inch casing leaving an annular space which is then filled with pre-cooled cement slurry made with local water. Thermocouples are provided on probes 7 within the annulus and all the thermocouple points are connected to a multi-channel recorder outside the cold room. Anti-freeze solution is then circulated through the six inch casing via pipes 10, 11 and the temperature allowed to fall and conditions stabilize for 2-3 days. Samples are taken from the tubes 6 and their salinity measured and a hydraulic hoisting device 12 is then attached to the casing and a vertical pull of 10,000 lbs sq. ft exerted. If the bond resists this pull then the cement is satisfactory and may then be thawed and broken up for visual examination.

Abstract: 1,041,590. Television. MARCONI CO. Ltd. Nov. 1, 1963 [Nov. 30, 1962], No. 45384/62. Heading H4F. A colour television camera comprises two image orthicon tubes 1, 2, means for projecting an image of a subject of transmission, e.g. the arrow in Fig. 1, on to tube 1, optical means including red colour filter 9, blue colour filter 11, dichroic or half-reflecting mirrors 4, 6 and ordinary mirror 7 for projecting red and blue images side by side on to tube 2, means for causing the scanning ray in tube 1 to scan the image projected thereon in lines extending thereacross, means for causing the scanning ray in tube 2 to scan across the two images projected thereon in lines extending across both images and any space therebetween and starting and finishing simultaneously with the starting and finishing of two lines in tube 1, and means for taking off luminance signals from tube 1 and chrominance signals from tube 2. The colour filters may be incorporated in the mirrors 6 and 7 or in the optical systems 8 and 10. The image on the luminance tube 1 contains all colours but colour trimming filters may be provided. Scanning in tube 1 is effected in accordance with television standards (Fig. 3, not shown) and scanning in the chrominance tube 2 is at a line frequency which is half that employed in the luminance tube 1 (Fig. 4, not shown). The spacing between the coloured images on tube 2 (Fig. 2, not shown) is typically about <SP>1</SP>/ 5  of the width of each coloured image in the direction of line excursion but by adopting a wave with a portion of reduced slope in the middle of the flank for scanning in tube 2 (Fig. 5, not shown) smaller values of spacing may be used. Tube 2 produces a red chrominance signal line during each alternate line in the luminance tube 1 and a blue chrominance signal line during each of the other alternate lines in tube 1. In the N.T.S.C. system both colour chrominance signals are required in each luminance line and therefore the output from tube 2 is fed to two chrominance signal channels one for the red and the other for the blue signals via branched paths and a double-pole change-over switch, one of the branched paths containing a delay line giving a delay equal to one line period of tube 1, the other paths being underlayed (Fig. 6, not shown).

The pulses appear sequentially on lines L1, L2 ... L32 and are indicated by lights l3, l4 ... l5, so that if the switch 22 of selection means 21 is operated providing a pulse on line 23, the AND gate 24 of the logic circuit 20 concurrently receiving a pulse from the counter will be turned on and the respective memory 25 set. Since the memory 25 subsequently provides an enable signal to the respective AND gate 27, when further pulses are received by that logic circuit from the counter they are passed to output line 28. A pulse is only passed through a particular logic circuit if the memory of that circuit is set. Lights (43) may be used to indicate which memories are set. Reset switch 26 operates on all the memories of a particular channel. An alternative selection means (31, Fig. 3, not shown) provides one selection switch (34) for each logic circuit rather than one switch 22 for a whole channel.  On providing a sequence of pulses from the counter to scan the logic circuits rhythm signals are supplied via line 28 to a voicing circuit (16) which drives a loud-speaker (17). The voicing circuit may have a plurality of separate inputs each one corresponding to one of a plurality of various unpitched instruments, e.g. cymbals, bass drums, snare drums. Each of the programmable channels may be associated with a particular instrument, or switchable to a selected instrument, or even two instruments simultaneously. The inputs to the voicing circuits may be switchable to fixed, (non-programmable) rhythm channels as well as the programmable channels.
