Title: Phasesynchronising device
IPC: H03L7/081
Filed: 1973-01-08
Abstract: 1366472 Counting apparatus THOMSON-CSF 8 Jan 1973 [11 Jan 1972] 1014/73 Heading G4A [Also in Division H3]  A shift register shown in block form as 2 comprises n bi-stable trigger stages having their respective outputs coupled to the following stage input via n AND gates which receive at the other inputs a first signal derived from a control circuit 51-58. The bi-stable outputs are also coupled back to their respective inputs via further n AND gates which receive at the other inputs a second signal from the control circuit. The control circuit also applies clock pulses to each of the bi-stables. Thus in response to the first or second control signal, a non-zero bit is transferred either forward or backward. Further the output is coupled back to the input. The shift register is used in a digital data synchronizing system (see also Division H3).

Title: Improvements relating to the manufacture of artificial silk
IPC: D01F2/06
Filed: 1931-01-13
Abstract: Artificial filaments of high dry and wet tenacity and elongation are obtained by extruding viscose into a heated coagulation bath containing dilute sulphuric acid, removing the thread from the bath after a very short time, allowing a short time for partial setting, and subjecting the thread to a gradually increasing tension while the coagulation is being completed by the liquid adhering to the thread, or by another coagulating medium.  The strength of the sulphuric acid should be between 8 and 20 per cent and there may be added salts such as sodium, zinc, and magnesium sulphate, and other substances such as glucose, dextrine, and gums.  The temperature of the bath should be between 55 DEG  C. and 80 DEG  C.  The period of partial setting is 5-30 times the period of immersion, and the stretching period is 20-70 times the period of immersion.  It is preferable to pass the thread over a final stretching drum which has a speed somewhat greater than that of the winding device.  Improved results are obtained when unripened viscose prepared from unripened alkali cellulose is employed.  When coagulation is completed by a second liquid, one or more of the stretching discs may be immersed therein, or the liquid may be sprayed upon the thread.

Title: Improvements in electric remote control and signalling apparatus
IPC: H02J13/00
Filed: 1926-01-16
Abstract: 246,466. British Thomson-Houston Co., Ltd., (Assignees of Eastman, A. V.). Jan. 26, 1925, [Convention date]. Wired wireless systems; controlling signalling and other apparatus; thermionic valve circuits.- In an electric signalling and remote control system utilizing high-frequency currents impressed upon a power-distribution system, the transmitter comprises a valve generator 6 supplied with alternating current from the power lines 1, 2,3, and arranged so as to produce high-frequency currents during the positive half-cycle of the supply voltage. The receiving apparatus comprises discharge tubes 13, 16 adapted to operate only when the voltage applied thereto is greater than a predetermined value. The discharge tubes are connected oppositely across a source of polarizing voltage which is derived from the power lines and is of a value just below that required for producing discharge. Hence at any instant a small additional voltage produced by the high-frequency signalling currents causes a discharge through the tube which has positive voltage impressed on its anode at that instant, no discharge taking place through the other device since the impressed voltage is insufficient to overcome the opposite polarizing effect. The phase of the transmitter generator supply is adapted to be displaced through 180 by switch 7, so that one or other of the tubes may be operated. At the receiving station the secondary of a distributor transformer 10 supplies a circuit comprising an inductance 11 and condenser 12 which is timed to the transmitter frequency. The discharge tubes 13, 16 are connected in series with polarized relays 14, 17 respectively and in parallel across the condenser 12. Condensers 15, 18 by-pass the high-frequency current around the relays 14, 17. The parallel circuit includes the secondary of a transformer 19 which opposes the voltage impressed upon the tubes by the transformer 10 and thereby producing a resultant voltage having a value below that at which discharge takes place. Loads may be supplied by the transformer 10, choking coils 22, 23 being inserted in series with the loads to prevent interference with the high-frequency currents. A condenser 24 is provided to counterbalance the effect of the coils 22, 23 upon the tuning when the load is removed. In a modification, the tuned circuit at the receiver is coupled directly to the power mains.

A gas lighter is operated by means of a lever E which when moved in the direction of the arrow rocks about its rear tubular pivot 1 and depresses a link 5 by means of downwardly opening semi-circular recesses 3 which fit. over the link. pivot 4, the link in turn being pivoted at its top end 6 to a member 8 carrying a catch. 7 which rotates. about flint wheel spindle 9 and drives the flint wheel 10 by engaging ratchet teeth 21, Fig. 4 (not. shown), on one side of the wheel. The pivot points 6, 9 and 4, when the lighter is inoperative. lie substantially in a straight line. Also as the lever E is actuated a projection 15 contacts one end of a lever 16 and depresses it against the action of a spring 17, the lever 16 pivoting at 9 and its opposite forked end lifting off a collar 24 on burner nozzle 22 so that a spring 23 and the gas pressure will open the gas valve F. The link 6 carries a pivot 12 for a bar 13 provided with a notch in which is engaged one end of a hair-pin spring 14, the other end of which abuts the upper wall of the gas container B. The springs 14 and 17 return the levers E and 16 to their inoperative positions, respectively. The lever E has a front extension 28 which on the lever's return stroke abuts against the spindle 9. The flame height is adjusted by rotating a wheel 25 which alters the throttling action of a member 26. A hood D retains the lever E in position and is held on to the lighter head A by a snap system 30 at its front end and by a projection 31a of a sliding bolt 31 acted upon by a spring 32 at its rear end.

Abstract: 1350332 Forming ultraviolet and blue radiation masks and filters from silver salt images EASTMAN KODAK CO 12 Jan 1972 [15 Jan 1971] 1460/72 Headings G2C and G2J A photographic image that is opaque to ultraviolet and blue radiation and transparent to visible light having a wavelength over 500nm. is formed by reacting an imagewise distribution of a waterinsoluble silver salt with an aqueous solution of a heterocyclammonium salt (i.e., one which forms a complex with a water-insoluble silver salt image which has a density in the ultraviolet and blue regions of the spectrum at least equal to the density of the silver image from which the silver salt image was produced or the density of the silver image which would have been produced if the silver salt image had been developed to a silver image) so as to form an imagewise distribution of the corresponding heterocyclammonium complex of silver. A radiation sensitive silver salt may be exposed, developed and fixed to form a negative silver image which is then oxidised to form the imagewise distribution of a water-insoluble silver salt e.g. using a photographic bleach solution such as a solution containing potassium ferricyanide and KBr. The negative silver image may be oxidized to the water-insoluble silver salt and immediately converted to the heterocyclammonium complex by treatment with a solution containing a heterocyclammonium salt having a nitro substituent and/or a nitrate anion. A radiation sensitive water-insoluble silver salt may be exposed, developed to form a negative silver image and a positive distribution of water-insoluble silver salt, treated with a non-oxidizing heterocyclammonium salt to form a positive distribution of the complex and bleached and then fixed to remove the negative silver image. The heterocyclammonium salt may be N-methylquinolinium iodide, N-(2, 4-dinitrophenyl) pyridinium chloride or 5-nitroquinolinium nitrate. The invention also comprises a photographic mask comprising a transparent support bearing a layer containing a complex of a hetercyclammonium salt as defined above, and silver, the complex being opaque to ultraviolet and blue radiation and transparent to visible light having a wavelength over 500nm. These masks are useful in the photo-fabrication of electrical devices e.g. circuit preparation, and in photo-mechanical reproduction.

Abstract: 1302711 Digital data recording system VIATRON COMPUTER SYSTEMS CORP 12 Jan 1970 [10 Jan 1969] 1477/70 Heading G4C The invention relates to a data recording and readout system. Data is recorded in data cells on magnetic tape, the data cells being defined by spaced flux changes on the tape and data being defined by the presence or absence of flux changes in the centre of each cell. Data is stored on two tracks, one track having flux changes at a cell centre to indicate a "1", the other track having flux changes at a cell centre to indicate a "0". Data pulses are delayed a time equal to half the period of a cell by a system clock at two AND gates (Fig. 6) which feed two OR gates receiving timing signals t*. A flip-flop is fed by each OR gate so that the flip-flop changes state at the beginning of the memory cells defined by clock pulses t* and at the centre of all cells containing a delayed data pulse, the pulses indicating a "1" on one track and a "0" on the other. Data read from tape is self-clocking and selfchecking. Data on the two tracks A, B is fed to the circuit shown in Fig. 7. Portions 16, 17 check the A and B tracks, respectively, and compare the halves α 1 , α 2  or # 1 , # 2  of each cell. For the A track if the portions stored in the two flip-flops marked α 1 , α 2  differ during a clock pulse # * and during the second half of each cell a "1" is stored. Similarly if d* is "1" a zero is stored. The d*, d* outputs can be compared to check for errors. Portion 18 of the circuit produces an output in the second half of each cell if the contents of corresponding cells on each track differ which output enables AND gates in portions 16, 17.
