Title: Single side-band carrier systems
Inventor: SMITH DAVID HESELTINE
IPC: H04B1/68
Filed: 1966-07-22
Abstract: 1,126,788. Single sideband modulation; multiplex carrier systems. COMMUNICATIONS CONSULTANTS Ltd. 31 Aug., 1967 [22 July, 1966], No. 33137/66. Headings H3R and H4R. A single sideband modulator of the type comprising means (48, Fig. 2) for splitting an input signal into two quadrature components, means (54) for splitting a carrier wave into two quadrature components, two balanced modulators 50 and 52 fed with the quadrature input and carrier signals, and means (56) for combining the outputs of the balanced modulators, is characterized in that the balanced modulators comprise diodes and resistances (72, Fig. 3, not shown) and are constructed as an integrated circuit with the other units mentioned above. The output means 56 is preferably an FET amplifier, and the phase splitting unit 48 may be preceded by a filter 44 and an FET amplifier 46. Fig. 2 shows a multiplex telephone system wherein the carrier for the first channel is provided from a master oscillator 40 which also feeds a network 42 of dividers, filters and multipliers, this network providing 11 other carrier waves at 4 kc./s. intervals. The 64 kc./s. signal from oscillator 40 is transmitted as a pilot signal and recovered at the receiver by a filter 66 and supplied to unit 68 which re-generates the required carrier waves at the receiver. In Fig. 2, the components fed to the modulators 50A and 52A in the second channel are such that the output from the channel is in phase quadrature with the output from channel 1; similarly channel 3 is in phase quadrature with channel 2, so that cross-talk is reduced. As an alternative, Fig. 4 (not shown), each sideband may comprise two quadrature components carrying different information signals thereby doubling the number of channels in a given bandwidth.

Abstract: 1508971 Data transmission; ciphering SIEMENS AG 27 Aug 1963 [27 Aug 1962] 33825/63 Heading H4P In a system for enciphering, transmitting and deciphering teleprinter signals which are transmitted from a transmitting station to a receiving station, (i) a series of unciphered teleprinter characters are enciphered by mixing with a series of message cipher characters produced from a message cipher generator at the transmitting station, the enciphered characters so formed being transmitted to the receiving station, (ii) separate synchronizing means provided at the transmitting station and the receiving station operate continuously, during both message transmission and pauses in message transmission, (iii) a message cipher generator at the receiving station is operated in synchronism with the message cipher generator at the transmitting station to produce an identical series of message cipher characters, (iv) the series of enciphered message characters received at the receiving station is mixed with the series of message cipher characters produced at the receiving station to produce the original series of unciphered characters, and (v) means are provided at the transmitting station to continuously transmit cipher signals during pauses in message transmission. Preferably, during pauses in message transmission a pause cipher distinct from the message cipher is transmitted from the transmitting station to the receiving station. At the transmitting station "message start" and "message end" signals cause the pause cipher to be switched in and vice versa, respectively: The "message start" and "message end" signals are mixed with the message cipher before transmission, and after mixing with the message cipher at the receiving station the resulting unciphered "message start" signal is employed to effect recording or read-out of the following signals and the resulting unciphered "message end" signal is employed to terminate read-out or recording of the received signals. The start and stop elements of start-stop teleprinter characters are employed to check synchronism between the transmitting and receiving stations. The transmission of a special service code results in the direct connection of a service teleprinter to the transmission line at the receiving station.

Title: Production of saturated aliphatic nitriles
Filed: 1945-12-14
Abstract: Saturated aliphatic nitriles are prepared by reacting a saturated aliphatic alpha, omega-dihalide with a metal cyanide in a liquid reaction medium comprising an ether-alcohol which will dissolve at least 1 per cent by weight of the dihalide and of the metal cyanide. In addition to the ether-alcohol, other solvents such as water, methyl alcohol or ethyl alcohol or non-solvent diluents such as hydrocarbons may be included in the mixture and a catalyst such as an iodide may be used.  The reaction is preferably conducted at elevated temperature and increased pressure may be used.  In examples: (1) 1,4-dichlorobutane is added to a heated mixture of sodium cyanide in monomethyl ether of ethylene glycol and the mixture boiled, the products are adiponitrile and deltachlorovaleronitrile; the latter may be converted to adiponitrile by further treatment with sodium cyanide; (2) ethylene dichloride is added to a heated mixture of sodium cyanide in tetrahydrofurfuryl alcohol, the mixture is further heated, succinonitrile being obtained; (3) succinonitrile is obtained by adding ethylene dichloride to a heated mixture of sodium cyanide, ethylene dichloride and monomethyl ether of ethylene glycol; (4) 1,4-dichlorobutane, sodium cyanide and monomethyl ether of ethylene glycol are heated under reflux, the resulting salt filtered off and the solvent and unreacted dichlorobutane distilled under reduced pressure.  This distillate is returned to the reaction flask and dichlorobutane and sodium cyanide added so as to maintain a substantial excess of dichlorbutane.  The above procedure is then separated and the following products are recovered by vacuum fractionation: delta-chlorovaleronitrile, adiponitrile and 1,4 - dichlorobutane. Additional starting materials specified are ethylene dibromide, 1,4-dibromobutane, 1,5-dichloropentane and 1,6-dichlorohexane and as metal cyanides, potassium cyanide, cuprous cyanide, calcium cyanide and zinc cyanide are also specified.  Other ether-alcohols mentioned are the monoalkyl ethers of ethylene glycol, e.g. the monoethyl- and mono-butyl-ethers; the mono-aryl ethers of ethylene glycol; the mono-alkyl ethers of diethylene glycol and of tetramethylene glycol; the dialkyl ethers of glycerol.  It is stated that the nitriles may serve as intermediates in the preparation of dicarboxylic acids, diamides, diesters and diamines.

Abstract: 996,593. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Sept. 22, 1961 [Sept. 23, 1960], No. 33967/61. Heading H3B. [Also in Division H1] A magnetic memory element for a random access memory comprises a thin anisotropic film having perpendicular hard and easy magnetization axes which may be turned to any desired position by a magnetic field at room temperature, a write-in means which produces a field of sufficient magnitude and duration to turn the said axes, and a read-out means having a command field insufficient to turn said axes and an inductive pick-up means whose coupling to the command field depends on the position of the axes. In Fig. 1, the magnetic film 3 is shown with drive wires 1 and 2 and read-out pick-up wire 4. To write in, a pulse of sufficient amplitude and duration (e.g. 1 second) is fed to both drive wires so that the resultant magnetic field turns the hard magnetic axis in the X or Y directions (representing binary 0 or 1) depending on the direction of the current in each drive wire. To read out, square waves of relatively low amplitude are fed to the drive wires. If the Y direction is the axis of hard magnetization (i.e. a 1 is stored in the device) a signal is obtained from the pick-up wire, whereas if the X direction is the hard axis there is substantially no output. Read-out time may be less than one microsecond, and the store may be read repeatedly without damage. Specification 996,591 is referred to.
