Abstract: 1,163,457. Colour television. INTERNATIONAL POLAROID CORP. 3 Feb., 1967 [4 Feb., 1966], No. 5413/67. Heading H4F. In a colour television apparatus operating in accordance with the "red-white" principle of colour reproduction in which a red image is produced in response to a red signal (R) on lead 11 and a superposed white image is produced in response to a green signal (G) on lead 13, an improvement in colour reproduction is brought about by the arrangement of inverters 39, 43 and summing circuits 37, 41 whereby a small portion of each signal, of the order of one part in ten, is subtracted from the other. The invention is described as applied to a receiver for use in a system in which the transmitted signal comprises a luminance component and a colour subcarrier subjected to phase and amplitude modulation in accordance with colour information. Signals R and G are derived by colour decoding circuit 9 and the images are reproduced in response to the modified signals R<SP>1</SP> and G<SP>1</SP> by a cathode-ray tube 23 having a laminated phosphor screen, the colour from which is changed between red and white by control of the beam velocity by high voltage switch 33. The signals R<SP>1</SP> and G<SP>1</SP> are applied to modulate the tube alternately at vertical scanning rate by gates 49 and 51 which are controlled by a multivibrator which also triggers the switch 33.

Title: Electronically controlled synchronous electromotor
Inventor: DALEN CHRISTIAAN JOHANNES VAN
IPC: H04L17/12
Filed: 1953-02-26
Abstract: 748,343. Electric motors. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Feb. 26, 1953 [March 6, 1952], No. 5447/53. Class 35. [Also in Group XL (b)] An electromotor in which the pole pitch of the stator is different from that of the rotor is controlled by electronic means comprising a two-position trigger circuit operated by a starting impulse to a second position in which a multivibrator is brought into action producing at a predetermined frequency pulses which control an electronic counting circuit, the valves of the latter when rendered non-conducting operating further valves equal in number to that of the stator poles and energizing in succession the stator windings. The number of poles on the stator and rotor may be the same or different. As applied to a perforated-tape transmitter, for the sequential sensing of the perforations the motor advances the tape stepby-step corresponding to the positions of sensing fingers disposed on a line inclined to the transverse to the line of perforations and associated electronic means controlled by the presence or absence of a perforation opposite a sensing pin are effective to transmit the code signal elements, start and stop elements being automatically transmitted when the arrangement is initiated into action and is in its final (or rest) condition respectively. In the latter condition, the valve V1 is conducting, the valves V5 to V1 conducting, V12 to V23 non-conducting and V24 conducting to energize the stator coil S7 to hold the motor in its final position. On the application of a control pulse at Stl, V1 becomes non-conducting and applies a positive pulse to the screen grid of the valve V4 to trigger the multivibrator V3, V4 into oscillation at a frequency of 50 cycles. A negative pulse from V2 makes V5 non-conducting and a positive pulse from its anode circuit makes valves V12, V13 conducting, thus energizing coil S1 of the first stator pole and operating relay A to send a start impulse to line. V5 returns to its conducting state and the fall in voltage at its anode load in combination with a negative pulse from the multivibrator renders V6 non-conductive so that valve V14 is conducting to energize stator coil S2 and V15 will operate the relay A to send a start polarity element unless a negative voltage caused by a sensing pin applying a negative potential at To1 to the grid of the valve V15 makes the valve non-conductive so that an element of stop polarity is sent. When V11 becomes non-conductive, a positive pulse makes V1 conducting and also V24 which energizes the stator coil S7 to hold the motor at its final position. When V11 returns to the conductive condition a positive potential applied from the anode of valve V2 holds the valve V24 in the conducting condition in which it remains until the start condition is applied for the next sequence of operations. Various arrangements of stator and rotor poles are described in connection with Figs. 4 to 7 (not shown).

Title: Transmission systems
IPC: H04L27/10
Filed: 1972-02-07
Abstract: 1363981 Digital transmission; synchronizing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Feb 1972 [10 Feb 1971] 5564/72 Heading H4P A synchronous f.m. system has a main clock generator providing clock pulses via a discretely adjustable frequency divider, which are applied to both modulator and demodulator. At the receiver, clock pulses are applied together with signals representative of zero crossings to a phase detector which applies a control signal to a second discretely adjustable frequency divider for synchronizing clock pulses with zero crossings. At the receiver clock pulse signals CS, ET, Fig. 2 (not shown), with inverse signals all having the same frequency fs are generated in frequency dividers (ZG, FFA &c.) data signals being sampled by a pulse series of frequency fs/2 from a gate G2 and are temporarily stored in a buffer comprising a flip-flop AF1 and gate G1. FM1 divides pulses CS by 2. The synchronized data output signal from AF 1 provides a balanced drive signal for a frequency modulator circuit formed by NAND gates G4, G6 connected to binary divider FM2. A binary 1 of frequency twice f2, the lower frequency, opens gate G4 with G5 closed; conversely a 0 opens G5 to pass twice f1, the higher frequency; these signals are passed through a ¸2 JK flip-flop FM2 and through a coupling stage comprising a diode limiter (D1, D2) and amplifier with (R6, C5) feedback acting as a low pass filter removing unwanted harmonics (see Fig. 14, not shown). A number of transmitters may be connected through the same 2 wire line to a single computer hence non-transmitting terminals are isolated from line by field effect transistors (T1, T2) acting as a switch disconnecting a transformer which then presents a high impedance to line. A number of receivers may be connected to separate 2 wire lines. Incoming signals after regeneration are sampled at clock rate CS and are temporarily stored in buffer flip-flop AF2 the outputs from which are delayed over two clock periods to Ts=2/fs by a shift register having stages SF1, SF2 connected to exclusive OR gates G8, G10 the output from which is delivered to a flip-flop AF3 providing a recovered output ED. Transmission speed may be adjusted manually by switching stages of a multistage frequency divider (EA-EE) Fig. 5 (not shown). The synchronizing circuit comprises a transition detector (FLD) the output from which together with clock pulses CS is passed to a phase corrector (PK) forming part of a phase detector (PHD) which controls a binary frequency divider (FFA) having a division ratio 1 : 32+1. The arrangement ensures that only one correction step is made at a time.

Title: Method of and/or apparatus for measuring the concentration of oxidising or reducing agents in water
IPC: G01N27/49
Filed: 1939-02-20
Abstract: 525,423. Determining physical qualities of materials ; liquid resistances. KENT, Ltd., G., and MEDLOCK, R. S. Feb. 20, 1939. Nos. 5660 and 17282. [Class 37] An apparatus for determining the concentration in solution of an oxidizing agent, such as chlorine or ozone, or of a reducing agent, such as sulphuretted hydrogen or sulphur dioxide comprises a vessel 1 through which the solution is caused to flow at constant rate, and electrodes 4, 5 immersed in the solution and energized by a battery 7 and variable potentiometer 8 so that the p.d. across 4, 5 is about 0.6 volts. The passage of current through the solution produces on the electrodes a polarizing film which is destroyed by the agent, the current-flow in the galvanometer 6 being a measure of the concentration of the agent. Preferably, however, a counter-current is caused to produce a null reading in the galvanometer 6 by adjusting the slider of the potentiometer 11, the position of the latter then indicating the concentration. For measuring concentration of an oxidizing agent, a large cathode and small anode are employed, the reverse being the case for a reducing agent. In Fig. 3, electrodes 19, 20 of platinum or other noble metal are wrapped round a stem 18 of "Bakelite " (Registered Trade Mark) seating in a base 25 of the same material and surrounded by a glass tube 27, preferably of "Pyrex" (Registered Trade Mark), a locating ring 33 being also provided. Solution admitted at 42 to a constant height, as determined by the overflow 43, flows through apertures 29 in base 25, past the electrodes and lateral pipe 30 and into outflow pipe 31. In order to netutralize the possible effects of other agents in the solution, the electrode apparatus may be duplicated and current-flow in the water before chlorination opposed against that in the water after chlorination, the difference depending on the chlorine concentration.

A method of producing an encapsulated electrical component, e.g. a transformer bobbin, toroid &c., comprising a first moulding operation to produce a first part of a thermoplastic material, contact or connecting pins or other conductor means being integrally moulded into position during said first moulding operation, positioning the electrical parts of the component on the first part and making the required electrical connections between the pins and electrical parts, and enclosing at least said electrical parts with further thermoplastic material which integrally unites with the first-mentioned thermoplastic part to form a hermetically tight seal therewith. The bobbin for a transformer may be moulded from polypropylene such that the connection pins 5 are secured in the material by initially loading them in the moulding die. The windings 7 and laminations 8 (Fig. 3) may then be positioned on the bobbin and necessary connections made. The bobbin is then placed in a moulding press, pins 5 engaging suitable holes in the die and a further moulding made to form a casing, integral with the bobbin, leaving only the tops of pins 5 uncovered. In a similar method for the encapsulation of a toroid, the toroid is located in a depression in the initial moulding. Further several components may be encapsulated together with the help of locating depressions. Mounting lugs and code markings may be formed into the material at the moulding stage.

Abstract: 716,903. Reservoir shaving brushes. YORATH, J. H. Oct. 16, 1952 [March 5, 1952], No. 5784/52. Class 19 A reservoir shaving brush comprises a hollow handle 2 having one open end and one end partially closed by a diaphragm 9, the diaphragm having an internally threaded aperture 9 into which is screwed a spigot attached to the brush head 1. A tube 7 passes from within the bristles through the spigot to connect the interior of the handle with the bristles. In the arrangement shown a movable plunger 3 is provided within the handle. The handle is charged with shaving cream from a collapsible tube, the threaded aperture in the diaphragm 9 being of such a size as to receive the threaded end of a standard shaving cream tube. Shaving cream is subsequently discharged into the bristles by exerting pressure on the plunger 3. A shoulder or a spring ring within the handle near its open end prevents the plunger from leaving the handle. In a modification a tube having its lower end closed except for a small hole slides in a substantially air tight manner over the handle. By closing the hole with the finger and moving the tube over the handle a corresponding movement of the plunger 3 may be obtained. The tube may be removed from the handle and replaced over the head of the brush, when the brush is not in use. In a further modification the plunger is replaced by a flexible container attached to the inside of the handle near its upper end. The flexible container is pressed directly.
