Title: Improvements in or relating to earth satellite radio communication systems
Inventor: MILNE KENNETH
IPC: H04B7/208
Filed: 1962-09-21
Abstract: 996,524. Radio signalling. DECCA RADAR Ltd., RANK-BUSH MURPHY Ltd., and BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Sept. 13, 1963 [Sept. 21, 1962], No. 36078/62. Drawings to Specification. Heading H4L. An artificial satellite is provided with means for receiving signals from a plurality of distant transmitting stations which each include a frequency translator which arranges that there is no overlap between the different frequency bands to be simultaneously used by the respective transmitters, each signal comprising a radio-frequency carrier modulated by the output of a frequency translator, means for separately demodulating the received signals, means for combining the various outputs from the demodulators so that the resulting signals occupy separate sections of a frequency domain, and means for retransmitting the combined signals as a modulation on a further radio-frequency carrier. The signal bandwidth from each station may vary from station to station and from time to time to suit the operational needs so long as the resulting signals when translated in frequency occupy non-overlapping frequency bands when combined in the satellite. At each transmitting station frequency translation of the incoming signals may be effected by single sideband modulators whose outputs frequency modulate a radio-frequency carrier, a different carrier frequency being used for each transmitting station. The satellite has a number of receiving channels corresponding to or greater than the number of transmitting stations, whose outputs are demodulated and combined to produce a baseband signal, in the form of single sideband modulated signals of the same bandwidths as the original information signals stacked contiguously in the frequency domain so that the total bandwidth is approximately equal to the sum of the bandwidths of the original transmissions. This baseband then modulates a radio frequency carrier by any convenient technique. Each receiving channel in the satellite may include a limiter and means for muting in the absence of a carrier. Means may be provided for bringing the relative strengths of the various received signals to appropriate values. The satellite may include means for frequency translation of some of the received signals and the means for combining the outputs from the demodulators in the satellite may be arranged to invert the frequency range of the signals from one or more of the stations, as by using upper or lower sidebands, to reduce the noise level. The retransmission from the satellite may be shared by two or more transmitters at least one transmitting only part of the total bandwidth.

Title: Improvements in or relating to lubricating oil additive compositions and to lubricating oil compositions containing them
Inventor: AGIUS PETER JOSEPH VERMONT JAM
IPC: C10M169/00
Filed: 1955-12-20
Abstract: Compositions useful as detegent additives for lubricating oils, particularly mineral oils, comprise a blend of the reaction product of a divalent metal base, an alkylated phenol and a sulphurizing reagent with an oil-soluble copolymer of an unsaturated nitrile and one or more copolymerizable unsaturated organic esters.  The divalent metal is preferably a Group II metal, examples being calcium, barium, strontium, magnesium and zinc.  The alkyl substituent of the phenol is preferably a C4-C12 radical, isooctyl being particularly preferred.  Suitable sulphurizing agents are elemental sulphur and sulphur mono- and di-chlorides.  The reaction products are believed to have one of the following formul  <PICT:0800964/III/1> or <PICT:0800964/III/2> where M is the divalent metal, R is the alkyl substituent of the phenol, and n is between 2 and 5 inclusive.  The nitriles have the general formula R-C­N, where R is a metal-free organic group containing 2 to 24 carbon atoms and one olefinic double bond which is preferably conjugated to a carbonyl or nitrile group. Acrylonitrile is preferred.  The ester may be that of an unsaturated alcohol such as vinyl, allyl, or crotyl alcohol and a saturated acid, e.g. vinyl acetate, or that of a fatty alcohol and an unsaturated acid such as fumaric, maleic, itaconic, acrylic, and methacrylic acids, and preferably contains between 2 and 24 carbon atoms.  The copolymer is preferably formed by free-radical polymerization, through cationic and anionic polymerizations are also suitable. Examples of catalysts for all three forms of polymerization are given.  In an example, an additive composition consists of a copolymer formed from palm kernel fumarate, vinyl acetate and acrylonitrile blended with sulphurized barium dioctyl phenate.  This blend is contrasted with sulphurized barium di-octyl phenate used alone or blended with calcium sulphonates and phosphosulphurized alphapinene.

Filed: 1973-08-03
Abstract: 1405213 Controlling polyphase induction motors HITACHI Ltd 3 Aug 1973 [14 Aug 1972 30 Aug 1972] 37024/73 Heading H2J A control system for a 3-phase induction motor IM, preferably for use in a lift system SE, comprises a rectifying bridge RE comprising at least one pair of thyristors TH1, TH2, and switching means consisting of relay-operated contactors M1-M3 and B1-B2, whereby in a motoring mode and with contacts M1-M3 closed, the thyristors TH1, TH2 are connected between one input terminal, e.g. W, of a 3-phase supply and a corresponding input terminal w of the motor IM in anti-parallel configuration, whereas in a braking mode the contacts B1, B2 are closed connecting the A.C. terminals a 1 , a 2  of bridge RE to two input terminals of the source, e.g. V, W, and the D.C. terminals of the bridge d 1 , d 2  to two input terminals v, w of the motor. In the particular embodiment shown, a tachogenerator TG supplies a velocity dependent signal to a D.C. coil CF of a magnetic phase shifter MPS, and a velocity control pattern generator supplies a signal to a second D.C. coil CC of the shifter MPS. Two A.C. coils CA2, CA1 are supplied with respective A.C. signals from secondary windings of transformer TR and the phase in the secondary circuits and hence of gating signals to the thyristors TH1, TH2 are dependent upon the difference of the two D.C. inputs to the shifter MPS. In the motoring mode, since the main conducting paths of the thyristors are supplied with the difference between the u-w and v-w line voltages, the transformer primary is similarly supplied via resistances R6-R8, R7, R8 being equal in value, the contact MX5 being closed. In the braking mode, the contact MX5 is open since the thyristors only receive line voltage v-w. Up or down operation is controlled by contacts U1, U2 and D1, D2 respectively, and an e.m. brake MB is used to stop the car at a desired position.

Title: Patterning method and apparatus
IPC: D06B11/00
Filed: 1977-09-06
Abstract: Above a conveying device for advancing a printing material in accordance with the pattern, there is a chamber (24) which is intended for receiving a substance containing ink or adhesive, for example, and is arranged in at least one pattern carrier preferably constructed as an operating beam (2). Extending through said chamber (24) are guide sleeves (14) in which rams (1) present as plungers can be displaced in the axial direction. The guide sleeves (14) have at least one wall opening (114) via which their interior can be connected to the printing substance chamber (24). The wall openings (114) only form a connection between the interior of the guide sleeves (14) and the printing substance chamber (24) when the rams (1) are in their upper position. By axial displacement of the rams (1) into their lower operating position, said wall openings (114) can be sealed tightly. Due to the fact that the degree of filling of the cannula-like guide sleeves (14) is variable, high-pile or loop material can also be provided with a quantity of the printing substance which is sufficient for printing through. Applying very small quantities of the printing substance, for example to film-type material, likewise poses no problems. <IMAGE>
