Abstract: 1299088 Multiplexing electrical signals optically THOMSON C S F 17 Dec 1969 [17 Dec 1968] 59651/69 Heading G1A [Also in Division H4] Apparatus for multiplexing and de-multiplexing electrical signals employs a modulator for displaying the frequency spectrum so that a mask can be used in an optical interlacing means as a filter to suppress some frequencies in each signal. The multiplexing arrangement shown in Fig. 3 employs a plurality of sources of monochromatic light 7, 8 each having associated with it lenses 9, 10 for focusing the light in plane Áv. The electrical signals that are to be multiplexed S 1 , S 2  are connected to electro-optical transducers 11, 13 which phase modulate the light output so that its passage through phase contrast filter 15, 16 produces at 0 1 , 0 2  amplitude modulated light in the form of lines parallel to axis y 0  spaced apart along the x 0  axis. Filters 17, 18 comprising transparent and opaque zones in the form of slots and parallel bars block some of the spectrum lines from being transmitted to mirror 19. By staggering the filters the odd and even frequency bands of the spectrum can be selected for each of the modulated light beams. These outputs are collected by lenses 20, 21 and combined by semitransparent mirror 19 to give an image in plane x i , y i , which is analyzed by slit 25 passing light to photo-electric transducer 24 whose output is a  multiplexed signal of S 1  and S 2 . To de-multiplex the signal similar apparatus is employed except that only a single monochromatic light source and electro-optical modulator is needed. The composite light is segregated into its constituent parts by means of similar filter arrangements, whose position will determine which constituent light signal is analyzed, Fig. 4 (not shown). The spacing of the bars and slots in the filters can be varied to reduce problems associated with the production of secondary diffraction images. It is also possible to use a single filter grid by coating one face of the bars with reflective material, Fig. 5 (not shown). For low frequency signals the de-formation type electro-optical transducer is replaced by a loop of photo-chromic material which is driven at constant speed, Fig. 7 and 8 (not shown). In this apparatus the signal is used to modulate an ultraviolet light which provides a variable transparency on the photo-chromic material which optically modulating a coherent beam. After passing through the light beam the material is exposed to infra-red light which erases the modulation before it passes to further modulator systems for each of the signals to be multiplexed. The de-multiplexing arrangement using similar components is described in relation to Fig. 8 (not shown).

IPC: D01H7/92
Abstract: 608,930. Textile drafting apparatus. ABBOTT MACHINE CO. April 15, 1946, No. 11485. Convention date, Aug. 24, 1945. [Classes 120(i) and 120(ii)] Apparatus for drafting slivers of textile fibres has two sliver engaging members located between two pairs of drafting elements, such as rollers, one, at least, of the members having a sliver engaging surface extending transversely of its axis of rotation and in a plane approximately parallel to the line of contact of the front pair of drafting elements, the axis of rotation being offset from the path of travel of the sliver. In the apparatus shown in Figs. 1 and 2, a sliver S is passed through a trumpet 19, a pair of drafting rollers 12, 13 between two discs 25, 26, to drafting rollers 10, 11. The discs may have flat or slightly concave operating surfaces and the lower disc is positively driven from a shaft 34, while the upper disc 26 is driven frictionally by a collar 36 on the same shaft 34. The upper disc 26 rests upon the sliver and the pressure exerted upon the sliver may be adjusted by loading the disc with weights or springs, or by replacing the upper disc with one of different weight. In machines where the trumpet 19 is traversed, the discs 25, 26 and shaft 34 may be traversed simultaneously. Since the discs 25, 26 rotate in opposite directions on opposite sides of the sliver, their movement effects the twist in the sliver, initially to decrease and secondly to insert twist. It is stated that, when the invention is applied to the woollen system of drafting where two pairs of drafting rollers may be a considerable distance apart, the discs are placed near to the front rollers and impart a twist to the hitherto untwisted woollen sliver emerging from the back rollers.

The multi-vibrator FMV preferably provides pulses of very small mark/space ratio so that the system is immense from most spurious signals. As described, a smoke detector comprises inner and outer ionization chambers IC, OC having a source of radiation material. The transmitter P is powered along the signal line l 1 , l 2  by a source E. Field-effect transistor F1 is only energized when a short-duration pulse is supplied by FMV (or by a tunnel diode circuit) to its source electrode. The voltage at point T is such that F1 only becomes conductive during the presence of smoke, and then turns on the transistor A, which triggers thyristor SCR, energizing the alarm relay L. The amplifier supply is stabilized by Zener diode ZD. A diode bridge may be connected to the line terminals so that the transmitter P may be operated from lines of either polarity or from A.C. The ionization chambers may be replaced by sensors of temperature, moisture &c.

In a pressure compensating device for oil-filled cables, an oil-filled container 1 connected with the cable and housing a number of flexible gasfilled cells 3 which are connected with one another and with a gas pressure plant, some or all of the cells are fixed in a frame 2 which moves vertically in accordance with fluctuations in oil pressure. The frame 2 may carry a rod 7 having a head 8 which moves within the bore of a float 9 normally closing contacts 10, 11. Excessive movement of the frame 2 operates a warning device by breaking the contact between 10, 11. When the frame sinks, head 8 engages lugs 12 and draws the float down. When the frame rises, head 8 strikes flap 13 which pivots and pushes the float down. Air escaping from the cell rises to the top of the container causing the oil level, and thus the float, to sink. Alternatively the frame may exert a pressure proportional to its buoyancy against a diaphragm member filled with an indicating fluid and connected to a pressure gauge, or against a body composed of layers of graphite, the electrical resistance of which varies with change of pressure.
