Title: Improvements in or relating to decoder circuit arrangements in colour television receivers
Inventor: FREEMAN KENNETH GEORGE
IPC: H04N11/16
Filed: 1963-08-09
Abstract: 1,005,290. Colour television receivers. MULLARD Ltd. April 28, 1964 [Aug. 9, 1963], No. 31583/63. Heading H4F. The invention relates to a demodulator circuit for a colour television signal of the type in which two colour components I, Q, Fig. 3 (b), are modulated in quadrature on a sub-carrier signal, the phase of one of the components being reversed in alternate lines as indicated at IN and I R . In accordance with the invention the subcarrier signal is demodulated with the aid of two synchronous demodulations A and B, Fig. 3 (a), at phase angles A and B, Fig. 3 (b), which are symmetrically disposed with respect to the subcarrier component (Q) which is not subject to phase reversal during alternate lines, switch means 3 operating at line rate being provided either to reverse the connections of the subcarrier reference signals to the two demodulators (as illustrated), or to reverse the output connection 12 and 13 of the demodulators to the output signal channels. The switch operation is controlled by a square-wave signal applied at terminal 4 which is synchronized from the line time-base, and is established in operation in the correct phase in relation to the line sequential changes in the received signal by means of a special synchronizing signal included during the field blanking period. The invention is described more particularly as applied to the XZ demodulation system (see " Colour Television " by Carat & Townsend, 1961, p. 241 et seq.), two examples being given where the demodulation axes A and B are respectively Œ 17 degrees and Œ19À5 degrees with respect to the - Q axis of 213 degrees. A detailed circuit utilizing diode switching elements is described for switch 3 with reference to Fig. 4 (not shown).

Abstract: 1,001,183. Speed responsive brakes. ENGLISH ELECTRIC CO. Ltd. Sept. 13, 1961 [Sept. 13, 1960], No. 31589/60. Heading F2F. Braking apparatus for winding gear comprises weight, spring or fluid pressure means exerting a constant force W to apply the brake, and a variable release mechanism comprising a release cylinder 10 containing a piston 15 acting in opposition to the force W, a change-over valve 11 manually operated between application and release positions whereby fluid is respectively released from the cylinder via a port 14 or supplied to the cylinder via a port 13, a second change-over valve 16 adapted to connect port 14 either directly to exhaust via port 19 or to a restricted exhaust arrangement via port 20, the second valve being operated by a solenoid 22 controlled by a switch 42 responsive to the speed of the winding motor, whereby pressure in the cylinder 10 is prevented from falling below a predetermined value so long as the motor is operating above a predetermined speed, and a third change-over valve 23 operative such that the exhaust via port 20 is directed to either of two restricted exhaust arrangements according to whether the load is being raised or lowered. Valve 23 is operated by a solenoid 30 controlled by a switch 43 which is closed when the motor is operating to raise the load and opened when the load is being lowered. Each exhaust arrangement comprises a relief valve 26, 28, respectively, which comprises a valve member 33 which is acted on by a spring 34 to close an inlet 35 at a pressure determined by the compression of the spring. The springs are variably compressed by cam followers 36, 39 engaging cams 37, 40, respectively, each cam being adjustably secured to a shaft 38 which is geared to the winding mechanism so as to rotate part of a revolution between the upper and lower limits of wind. The cams are adjusted so that the back pressure of the relief valves falls to zero at the limits of wind and rises to a maximum intermediately, the valve 28 being set to give a higher back pressure than the valve 26. In operation, switches 42, 43 are open when the load is at rest so that cylinder 10 is exhausted and the brakes fully applied. When valve 11 is operated to release the brake the system remains unchanged until the motor is started, switch 43 then being closed or remaining open to select the appropriate relief valve according to the direction of movement of the load. When the motor speed exceeds 5% of its full running speed, switch 42 is closed. Valve 11 may then be moved to the application position so that the load is controlled by light braking which is gradually increased as the load approaches its other limit.

Title: Improvements in sound reproducing devices applicable to telephones, phonographs or the like
IPC: H04R1/22
Filed: 1925-03-09
Abstract: 258,137. Sykes, A. F. March 9, 1925. Magnetic instruments ; gramophone pick-ups ; diaphragms. - Relates to acoustic instruments, such as gramophonic sound recorders and reproducers and telephones, comprising a source of vibration, a member for transmitting the vibration, a utilizer of vibration and a sink for vibration, which sink is sometimes the utilizer, such as the diaphragm. According to the invention, the transmitting member is flexibly anchored at or near one end, and the amplitude of vibration of the impulsed part of the transmitting member is less for low frequency and greater for high frequency than the amplitude of vibration of the part of the said member connected with the sink or utilizer. As shown in Fig. I, a stylus bar 22 carrying a light conical diaphragm 21 is mounted to vibrate about an axis 14 near the stylus end, and has a reduced section 23 near the axis of vibration, so that the bar acts as a rigid lever for low frequencies while for high frequencies the vibration is transmitted as a ripple. The stylus bar may be a tubular one of aluminium or magnesium alloys, or may be of wood. The axis of pivoting may be damped by grease as described in Specification 252,228. Fig. II shows a telephone instrument in which a small conical diaphragm 21, constituting both the sink and the utilizer, is operated by a thin lever 25 attached to a vibrating armature 291. The diaphragm may dip into a ring of oil or other liquid seal 26. Fig. III shows a sound recorder or reproducer in which an iron ribbon 25 ending in a spiral 27 in a chamber filled with damping material is set between the poles of a magnet 29 having control windings 30. A recording or reproducing stylus 31 is located at a point along the ribbon which is anchored at the end 32. For low frequency the amplitude of vibration of the ribbon at the entrance to the sink 28 is greater than the amplitude at the impulsed part. A similar device adapted for the hill-and-dale cut is described. In another modification, the stylus arm of the sound-box described in Specification 243,395 is thinned down near the pivot so that high frequencies are transmitted as a ripple. As described in the Specification referred to, the stylus bar may be made of lead and may be damped by being encased in a tube of felt. The diaphragm, which may be a stretched sheet of rubber stiffened with cardboard, ivory or the like, is connected to the stylus bar by a number of taut cords so that it acts as a piston. Specification 222,174, 222,924, 227,162 and 256,280 also are referred to.

Abstract: Compounds of the general formula <FORM:0832288/IV (b)/1> and acid addition salts thereof, wherein Y1 and Y2 are hydrogen atoms or hydroxyl or etherified or esterified hydroxyl groups, R1 is a hydroxyalkylene group of 2-6 carbon atoms, the hydroxyl group being on the carbon atom adjacent to that to which the nitrogen atom is bound and R2 is an alkylene group of 2-6 carbon atoms are made by reacting a compound of the formula <FORM:0832288/IV (b)/2> with a compound of the formula <FORM:0832288/IV (b)/3> the group R5 being an alkyl group such that the carbon skeleton of -CH-CH-R5 is the same as that of R1, and converting if desired any esterified or etherified hydroxyl group Y1 and/or Y2 into a free hydroxyl group by hydrogenation or hydrolysis, and converting the amine into its acid addition salts, if desired.  The process is preferably carried out in a solvent such as an alcohol, ether or hydrocarbon at a pH of 7-11. Y1 and Y2 may for example be benzyloxy groups which are converted to hydroxyl groups by hydrogenation in the presence of a noble metal catalyst or Raney nickel, or Y1 and Y2 may be hydroxyl groups esterified by lower aliphatic carboxylic which are saponified by dilute acids or bases or are converted to hydroxyl groups by reduction with a complex metal hydride such as sodium-boron hydride or lithium aluminium hydride.  Preferred products include compounds of the formul  Y1-C6H4-CH(CHOH.CH3) -NH-CH2-CH2-O-C6H5, Y1-C6H4-CH(CHOH. CH3)-NH-CH(CH3)-CH2-O-C6H5 and Y1-C6H4-CH(CHOH.R5)-NH-R2-O -C6H4-Y2, R5 being a hydrogen atom or an alkyl group of 1-4 carbon atoms.  The products are used pharmaceutically.  In examples: (1) 1 - methyl - 2 - phenoxy - ethylamine is reacted with styrene oxide to give 1-phenyl-2-(11 - methyl - 21 - phenoxy - ethylamino) - ethanol-(1); (2) anethol oxide is reacted with 2-phenoxyethylamine to give 1-(41-methoxyphenyl)-1-(21-phenoxy - ethylamino) - propanol - (2) and (3) anethol oxide is reacted with 1-methyl-2-phenoxy - ethylamine to give 1-(41 - methoxyphenyl) - 1 - (11 - methyl - 21 - phenoxy - ethyl - amino) - propanol - (2).

Patent GB-850586-A (GB)
Title: Improvements in or relating to magnetic shift registers
IPC: G11C19/04
Filed: 1956-10-09
Abstract: 850,586. Circuits employing bi-stable magnetic elements. LABORATORY FOR ELECTRONICS Inc. Oct. 19, 1956 [Oct. 26, 1955], No. 31984/56. Class 40 (9). [Also in Group XIX] A shift register comprises magnetic cores each associated with a rectifier and a storage element, such as a condenser, the rectifier being biased so as not to conduct during a portion of each shifting pulse cycle. In one arrangement, Fig. 1, the first core 18 receives positive shift pulses from a generator 37 over a resistor 11 and a rectifier 12. If such a pulse re-sets the core, its winding acts as a high resistance and a storage condenser 15 connected across it is charged over a rectifier 14. When the shift pulse ceases, the condenser 15 discharges through the winding of the next core 28 which is thus set. The other possible discharge paths are blocked by rectifiers 14, 24 and 22, the latter being positively biased between the shift pulses by a second generator 38. The condenser 15 and a resistor 16 and an inductance 17 form a delay line to ensure that the pulse does not arrive at the core 28 until the rectifier 22 is blocked. The second core 28 receives negative shift pulses over the rectifier 22 at the same time as the positive shift pulses are applied to the first core 18 and if the core is re-set, a condenser 25 charges over rectifier 24. The action is the same as in the first stage but with polarities reversed. The third stage is identical with the first, the fourth with the second, and so on. A different arrangement, Fig. 2, employs a single pulse generator 62. The resistors 41, 47 have a resistance equal to that of a core winding when the core is being re-set and so, as the condenser 44 charges when the. first core 48 is reset, the rectifier 45 remains non-conducting. At the end of the shift pulse, the condenser 44 discharges through the resistor 47 and the winding of the second core 49 in parallel. In a modification, Fig. 3, each stage is identical and each core has a separate input winding. If a shift pulse applied to a winding 66 re-sets the first core 67, the condenser 71 charges and then discharges through the input winding 73 of the next core 74. Pulses, independent of shift pulses and all of the same sense, are developed at this time in the shift windings, e.g. 75, and may be used to provide a parallel output. A rectifier may be connected in series with the resistor 78 to prevent power loss as the core 74 is set, the rectifier being rendered non-conducting at this time by a suitable bias potential.
