Title: Satellite communications systems
IPC: H04B7/212
Filed: 1975-01-03
Abstract: 1488572 Satellite TDMA communication system SIEMENS AG 3 Jan 1975 [14 Jan 1974] 226/75 Heading H4M In a satellite communication system wherein transmitted bursts comprising TDM signal channels together with a preamble from different ground stations are combined in time staggered fashion to form a TDM block at a satellite and are retransmitted therefrom, the time required for phase correction of a burst before it is initially transmitted from a ground station is considerably reduced relative to that required in the prior art. For a particular ground station BSt2 to effect initial access it transmits an initial access signal (operation (a) (Fig. 3)) at a substantially lower level than effective signals to the satellite Sa, receives this initial access signal when retransmitted from the satellite and monitors the position of the signal as it appears in the TDM block (b). As a result of this the transmission phase at the ground station is adjusted to an intermediate phase, displaced from the desired proper phase at which burst transmission should occur by about half the possible tolerance in measuring the phase deviation between the initial access signal and the desired phase (c). The burst preamble adjusted to this intermediate phase is then transmitted (d) and is fine adjusted to the intermediate phase by a burst transmission phase control system making use of the ground stationsatellite loop (e). The burst preamble is next incrementally phase shifted by a programmed control arrangement not using the station-satellite loop to the desired phase (f). Thereafter the complete burst is transmitted (g) and held at the desired phase by the station-satellite phase control system.

Title: Improvements in synthesis of terpenoid materials
Filed: 1952-01-04
Abstract: The invention comprises a ketal of the general formula <FORM:0728446/IV (b)/1> wherein X is a halogen atom and R11 is an alkylene radical, and the preparation thereof by reacting a 5-halo-2-pentanone with either an alkylene glycol or an alkyl orthoformate.  Said ketal may be reacted with an active metal, e.g. Mg, Zn, Cd or Hg, to form an organohalometallic compound of the formula <FORM:0728446/IV (b)/2> or <FORM:0728446/IV (b)/3> wherein M is the active metal, or with lithium.  The organohalometallic compound reacts with an aldehyde or ketone of the formula <FORM:0728446/IV (b)/4> where R is a hydrocarbon radical and R1 is either hydrogen or a hydrocarbon radical to form a carbinol of the formula <FORM:0728446/IV (b)/5> which can be dehydrated with an acid dehydrating agent, e.g. oxalic acid, p-toluenesulphonic acid, acetic anhydride, zinc chloride, phosphorus trichloride, oxalyl chloride and phosphorus oxychloride, to form the compound <FORM:0728446/IV (b)/6> or <FORM:0728446/IV (b)/7> p  which upon hydrolysis with aqueous acid yields the unsaturated ketone <FORM:0728446/IV (b)/8> which upon hydrogenation yields the saturated ketone <FORM:0728446/IV (b)/9> As the alkylene glycol there may be used ethylene glycol, propylene glycol or butylene glycol, whilst the carbonyl compound may be pseudo-ionone, dimethyl ketone or methylheptenone.  The reaction of the ketal with the active metal is effected in the presence of methyl iodide.  The hydrogenation reaction may be effected in the presence of Raney nickel, platinum oxide or palladium.  5-Halo-2-pentanones are obtained by reacting an alkaline metal derivative of ethyl acetoacetate with ethylene oxide gas to form a -acetobutyrolactone which is reacted with hydrogen halide.

Title: Improvements in and relating to the production of ammonium sulphate
IPC: C01C1/24
Filed: 1918-01-05
Abstract: A mixture is made of nitre cake, sodium sulphate, ammonium sulphate, and water under such conditions that a quantity of anhydrous sodium sulphate is separated, and after the removal of the sodium sulphate, the liquor is used for absorbing ammonia from gases.  When used for treating Mond gas, the solution is diluted before the absorption of ammonia and then concentrated again. When treating coke-oven gas or coal distillation gas, this dilution and evaporation may be unnecessary.  The absorption of ammonia with the subsequent evaporation causes the separation of sodium-ammonium sulphate, which is removed, and a further evaporation causes the separation of ammonium sulphate, the double salt being used with more nitre cake for repeating the process. When dilution and evaporation are not employed, the absorption of ammonia causes the separation of ammonium sulphate, the mother liquor being used with more nitre cake for repeating the process.ALSO:A mixture is made of sodium sulphate, ammonium sulphate, and nitro cake under such conditions that a quantity of anhydrous sodium sulphate separates, and, after the removal of this sodium sulphate, the liquor is diluted and used for absorbing ammonia from Mond gas and then concentrated again, when sodium ammonium sulphate separates, and may be used with more nitre cake for repeating the process.

Title: Reactance amplifiers
IPC: H03F7/00
Filed: 1960-01-05
Abstract: 877,757. Parametric amplifiers. MICROWAVE ASSOCIATES Inc. Jan. 5, 1960 [Jan. 7, 1959], No. 397/60. Class 40 (9). A reactance amplifier comprises an elongated conductor 11 at least partially surrounded by an elongated conductor 10 the two conductors being coupled by a voltage-dependent reactance 12. The inner conductor is of such a length (e.g. #/4 that it may support a standing wave at signal frequency, the input and output circuits 28, 29 for the amplifier being positioned in the vicinity of the same voltage level of the standing wave. The pump frequency is connected via the coupler 14 to the voltagedependent reactance which may be a PN junction diode. The tuning capacitor C may be varied to adjust the resonance frequency of the cavity to that of the signal frequency. This capacitor may occupy the alternative position C<SP>1</SP>. In the embodiment shown the pump frequency is four times the signal frequency and the idler frequency (i.e. the difference frequency) is thus three times the signal frequency. With the presence of the inner conductor causing the propagation velocity to be the same for all these frequencies standing waves 35, 36, 37 are set up in the fundamental TEM mode for the signal, idler and pump frequency as shown in Fig. 2. The variable reactance 12 is situated at a point where the signal, idler and pump voltages are all appreciable, so that all these voltages may influence the reactor. In the absence of a pump frequency the energy is conveyed from input to output terminals without loss. In a modification, Fig. 3 (not shown), the inner conductor is telescopic and adjustable. One terminal of the variable reactor is then fixed to the moving part of the inner conductor and the other terminal is capacitatively coupled to the outer conductor. In a further modification, Fig. 4 (not shown) the outer cylinder is open ended and the inner conductor is doubled in length. Various other cross-sectional configurations for the conductors may be adopted, Figs. 5 . . . 8 (not shown). Although the apparatus may be dimensioned for idler and signal frequencies as mentioned above, the pump frequency may in fact be a multiple of the pump frequency mentioned.
