IPC: H05B41/22
Filed: 1970-02-03
Abstract: 1289958 Valve supply circuits TELEDYNE Inc 3 Feb 1970 [3 Feb 1969] 5115/70 Heading H3W [Also in Division H1] A bridge circuit 23, made up of resistors R 1 , R 2  and R 3  and Zener diode voltage reference 34, is integral with a travelling-wave tube and is connected between the voltage supply lines 21 and 22 of the cathode and the slow-wave structure electrode 16. After manufacture, a voltage source equal precisely to the desired interelectrode voltage is applied across lines 21 and 22, and the variable resistor 32 adjusted to a null reading on a microammeter 37 temporarily connected across the bridge. When the tube is subsequently incorporated in other apparatus, the voltage applied across lines 21 and 22 is adjusted until the microammeter 37 again gives a null reading, whereby the voltage supply may be correctly adjusted without the use of a voltmeter. One of the resistive arms of the bridge may include a series of taps from which the voltage for successive open anode electrodes are taken, the tap positions being set after manufacture (Fig. 2, not shown).

Abstract: 1295846 Hair-like filaments TOA BOSHOKU KK 18 Nov 1969 [12 June 1969] 56443/69 Heading B5B [Also in Division C3] Filaments suitable for use as imitation human hair are formed by melt spinning compositions comprising polypropylene or nylon, 0À5 to 10 weight per cent based on the polymer of at least one transparent extender pigment having a refractive index of less than 1À7 and in the form of particles of which at least 80 weight per cent have a diameter of 0À1 to 3À0 microns, and optionally a colour pigment. Preferred extender pigments are calcium and barium carbonates. The filaments may be stretched, e.g. at a ratio of 4:1 at 130‹ C., and set at a temperature of 135‹ C. The pigment particles are said to produce rhombic hollows in the filament surfaces, which reduce brilliance and slipperiness.

IPC: H03G9/18
Filed: 1969-07-21
Abstract: 1305622 Companders DOLBY LABORATORIES Inc 10 July 1970 [21 July 1969] 32684/70 Divided out of 1279634 Heading H4R Compressor or expander comprises a straight through path and means for combining therewith the output of a further path which takes its input either from the input or the output of the compressor or expander. The further path output may be combined to add to, or oppose, the signal in the straight through path. The further path includes a variable gain circuit and a variable cut-off filter for restricting the signals passing through the further path. The filter presents all pass characteristics at low level and introduces a high pass and/or low pass characteristic when the output level rises. The filter and gain control device may comprise a series arm with a capacitor and resistor in parallel feeding a shunt connected variable impedance which can be a pair of oppositely poled biased diodes, or the source drain path of a FET whose gate is fed with a D.C. proportional to signal level. A sharper filter cut off to provide more discrimination against noise and less noise modulation is given by the circuit of Fig. 3 which comprises a fixed high pass filter formed by C2 and R4 followed by the variable filter formed by C1 and the source drain path of FET 17. The further path also includes a clipper 21 to eliminate large transients which can pass through the gain control circuit due to the time delay of the smoothing circuit 20. A stronger low and mid frequency limiting characteristic can be provided by increasing the impedance of the filter circuit. In Fig. 4 (not shown) this is provided by removing R5 and returning R4 to the output of a unity gain amplifier fed from the output of the filter circuit. This has the effect of making R4 infinite during the time that the FET 17 is not conducting and lowering its impedance as the FET conducts. A further development, Fig. 5, includes two further paths one, 13, dealing with high frequency plus midband noise, and the other, 24, dealing with low frequency plus midband noise. An alternative, Fig. 6 (not shown), combines the two filter circuits of Fig. 5 to feed one FET.

Titanium dioxide may also be included. A fuse composition 7 is provided to ignite flare or smoke producing charges (not shown). The quickmatch 9 is ignitable by means of a cartridge cap or Bickford fuse 10 and is self supporting or is supported in a metal, plastic or paper tube (not shown). In another embodiment, Fig. 2, the quickmatch 17 extends towards a primed cambric element 19 for igniting the propellant charge 16. The copper chromate can be distributed in a discontinuous layer over the exposed surfaces of the propellant charge by sprinkling or dusting, or by applying a slurry of the copper chromate in a volatile liquid which is a solvent for the binder. Alternatively, where the copper chromate is intimately admixed with the propellant, the particles of copper chromate can be exposed by applying a suitable solvent to the propellant composition. The particle size of the copper chromate is less than 120 mesh (B.S.S.).

The indicator is used to enable a blind telephone operator to identify a calling line on a switchboard and the contacts are spatially arranged to match the sockets on the switchboard with the addition of a further column of primary contacts (11a) which identify the row in which the call exists. As shown each line to the switch board is connected both to the normal indicator lamp 13a and to a transistor 20 forming part of a trigger circuit 22 which operates oscillator 23 to produce the audio signal. The base of each transistor 20 is connected to a contact 11b. All connections forming a row of contacts are also connected together through diodes 15 and transistor 17 to contact 11a so that when a signal is applied to one of lines 13 earthing of contact 11a will produce an audible signal as will subsequent earthing of the respective row contact 11b thus identifying the calling line.

Abstract: 1324507 Semi-conductor devices MULLARD Ltd 28 Oct 1970 [18 Dec 1969] 61729/69 Heading H1K The base region 3 of a bipolar transistor comprises a series of mutually spaced high conductivity stripes 5 formed by ion implantation and separated by lower conductivity active portions 6 of the base region which may also be formed by ion implantation or may be diffused. The emitter region 2 may be a strip-shaped diffused region, preferably with a higher conductivity implanted portion actually defining the emitter-base junction. The implanted base stripes 5 lie across the longitudinal direction of the emitter region 2 and extend beyond it to join common diffused base contact regions 11. The stripes 5 may have breaks aligned along the centre of the emitter region 2, since here high conductivity parts would merely contribute to the emitter depletion capacitance. The ion dose used to form the stripes 5 is preferably sufficiently high to render the crystal locally amorphous, a subsequent annealing process producing recrystallization. Localization of implantation may be effected by focusing the ion beam or by the use of a chromium mask defined by etching through an electron-beam sensitive resist mask.
