Abstract: 1,113,373. Multiplex radio signalling. RADIO CORPORATION OF AMERICA. 15 Nov., 1966 [7 Dec., 1965], No. 51822/65. Heading H4L. In a dual standard television receiver, such as one for the reception of 405-line V.H.F. signals and 625-line U.H.F. signals, separate tuners and intermediate frequency amplifiers are provided for each kind of signal, but the sound components at intermediate frequency of one kind of signal only are extracted and are amplified in the I.F. amplifier for the other kind of signal. As described, video signals at intermediate frequencies from the output of a V.H.F. 405-line tuner 10, Fig. 1, are amplified, detected, and further amplified in units 14, 22, 24, respectively. Audio signals at intermediate frequency are extracted by a tuned circuit (Fig. 2, not shown) and are taken to the input of a 625-line I.F. amplifier 16. The intermediate frequencies are so arranged that the 405-line sound carrier and its side-bands fall within the pass band of the 625-line intermediate amplifier and that the 405 video carrier and its sidebands lower in frequency than the sound carrier fall outside the pass band of the said amplifier. A unit 20 detects the output from the amplifier 16 and produces a 405-line audio frequency output. When the receiver is switched to 625- line working, the detector 20 produces 625-line sound signals at intercarrier frequency, and these are further amplified in a unit 26 and are finally detected in a unit 28. The 625-line video signals at intermediate frequencies from the output of the I.F. amplifier 16 are detected in a video detector 18 and are amplified in the unit 24, which is switched from the 405-line detector 22 when 625-line signals are being received.

Abstract: 1,093,560. Stereophonic radio-receiving systems. RADIO CORPORATION OF AMERICA. Dec. 29, 1964 [Jan. 15, 1964], No. 52712/64. Heading H4L. In a decoder for stereophonic radio signals of the type including an L + R signal, sidebands of a suppressed subcarrier wave amplitude modulated by the L - R signal and a pilot signal of half the frequency of the subcarrier wave, the switching signal developed in the usual manner from the pilot signal is supplied via a power amplifier to the multiplex decoder and the composite stereo signal also is supplied via a power amplifier to the decoder. As shown, the 19 kc/s. pilot signal is separated at 12 from the signal from the F.M. detector 8 and the remaining signal is supplied via amplifier 14 to the centre-tap of the secondary winding of a transformer 16 supplying the stereo decoder 28. The pilot signal is supplied to a locked oscillator and frequency-doubler 20, the resulting 38 kc/s. signal being supplied via an adjustable phaseshifter 22, the power amplifier 24, and the tuned primary winding of the transformer 16 as a switching signal to the stereo decoder 28. The resulting left and right signals at 41, 52 respectively are at sufficient power levels to drive the loud-speaker directly. Networks 44, 45 and 54, 56 by-pass high-frequency and transient voltages which might damage the loud-speaker voice coil. A portion of the L+R signal is fed back from the junction of resistor 60, 62 as negative feedback to the amplifier 14 to linearize the phase-frequency response and reduce cross-talk.

In a syphonic device with a piston 15 and cylinder 14 an air inlet tube 20 extends from the leg 12 at the lower end and coacts with the piston rod 16 to form a valve to control the entry of air into the inverted U-pipe 10, so that when the piston 15 is raised and held so, the rod 16 prevents air from entering the pipe 10 via the tube 20 and a full flush occurs, whereas on release of the rod 16, without holding, air can enter the pipe 10 through the tube 20 to pass through a rod aperture 16a to disrupt the syphon for a partial flush. The tube 20 may be integral with the cylinder 14 or separate and attached to the pipe 10.

Abstract: 1481189 L-Aspartyl-L-phenylalanine esters AJINOMOTO CO Inc 10 Dec 1974 53457/74 Heading C3H A method for the production of an α-L- aspartyl-L-phenylalanine C 1-4  alkyl ester comprises reacting the hydrochloride or hydrobromide of L-aspartic acid anhydride with a C 1-4  alkyl ester of L-phenylalanine in an inert or substantially inert liquid medium (defined) in the presence of a C 1-4  alkanol and a strong acid selected from sulphuric acid, hydrochloric acid and monoesters of sulphuric acid with a C 1-4  alcohol. The alkanol is preferably methanol or ethanol in an amount 2-20% by volume of the liquid medium and the reaction effected at a temperature less than 60‹ C. The liquid medium may be water, a halogenated hydrocarbon (especially 1,2-dichloroethane), an ether, an ester (especially 1,2-dichloroethane), an ether, an ester (especially ethyl acetate), a hydrocarbon, a nitrile, a lactone, a nitrohydrocarbon or mixtures thereof. The ratio of L-phenylalanine ester to L-aspartic acid anhydride is preferably 1 : 1 to 10 : 1. The α-isomer may be separated from the #-isomer by (i) precipitation of the hydrochloride of the α-isomer by addition of hydrochloric acid to an aqueous solution of the α- and #-isomers; (ii) addition of acetone or methylethylketone to the solid mixture whereby the α-isomer dissolves as the 4-imidazolidinone which is then hydrolysed to the required compound; or (iii) formation of the α- isomer adduct from an aqueous solution with cinnamic acid, #-resorcylic acid, 3,5-dinitrophenol or gentisic acid, separating and dissociating the precipitated adduct.

Filed: 1969-11-03
Abstract: 1283968 Automatic exchange systems WESTERN ELECTRIC CO Inc 3 Nov 1969 [5 Nov 1968] 53714/69 Heading H4K In an automatic exchange certain subscribers having a single appearance on the switching network are provided with an auxiliary line circuit which responds if the associated subscriber's line is busy and is simultaneously required for a further call, causing a call waiting circuit (also having an appearance on the network) to be taken into use and connected directly to the subscriber's line. The Figure shows one (from a group of twenty) such subscriber S1 having an appearance R on the network and an auxiliary line circuit 13. If the subscriber is busy on a call over the appearance R and another call for the subscriber is received, the auxiliary line is marked via the number group and number group connector circuits 12 and 16. A relay in the auxiliary line circuit responds signalling to a call waiting preference and control circuit 15 which includes a relay allotting chain which selects one of a bank of ten call waiting circuits 14 for use and connects it via a cross-bar switch 201 to the subscriber's line. It also signals to the marker the number of the call waiting circuit selected. A tone signal is injected into the line and if there is no response is repeated once after a ten second interval. If the subscriber takes no action then the caller camps on the busy line via the call waiting circuit and ringing signals are applied to the line after the subscriber has replaced his receiver. If the subscriber responds after either tone signal by flashing his switchhook, he is connected to the caller and the original call is held. The subscriber can by further flashing of his switchhook, alternately connect the two calls. If while involved in a call accepted via the call waiting circuit the other party of the original call clears, then a further incoming call can arrive over the appearance R. If due to an error two call waiting circuits are selected simultaneously, an error relay operates, signalling the marker causing a trouble printer to operate. If after a call waiting circuit is selected the marker fails to complete the connection in a predetermined time the call waiting circuit is automatically released.

When the empty reel is running at the appropriate takeup speed, the wire is transferred to it from the full reel, the clutches on the main shaft 9 being operated to disengage it from the full reel and engage it with the reel on which winding has commenced. The drive from the auxiliary shaft 15 is then disconnected. Brakes 3a, 3b are associated with the transmission members 7a, 7b.
