Title: Non-synchronous phase shift communication system
IPC: H04L27/233
Filed: 1963-02-05
Abstract: 1,038,361. Data transmission; multiplex signalling. ROBERTSHAW CONTROLS CO. Feb. 5, 1963 [Feb. 6, 1962; Nov. 5, 1962], No. 4713/63. Headings H4L and H4P. In a phase modulation transmission system digital signals cause phase shifts of less than 180 degrees. Before transmission the phase shift signals pass through a filter which smooths the transition so that the change in phase takes place relatively slowly. Consequently, the phase variation in the transmitted signal is accompanied by a frequency change. The receiver derives the original data by reference to such frequency changes. The received signals, in one embodiment, are limited and differentiated. The resultant pulse train, which has a varying frequency, operates a flip-flop. A low-pass filter derives the average current from the flip-flop. This has a smoothly varying waveform of which the amplitude depends upon the frequency changes and change in amplitude upon the direction of the phase change. A toggle derives the original data from the waveform. In another embodiment two data inputs are signalled by way of a four-phase phase-modulated signal. The above-mentioned smoothly varying waveform feeds logical circuitry, Fig. 4 (not shown), which develops a four-level signal corresponding to the diplexed input data.

Patent GB-943317-A (GB)
Title: Phosphine oxides
IPC: C08G69/42
Filed: 1962-02-07
Abstract: The invention comprises phosphine oxides of the general formula: <FORM:0943317/C2/1> wherein R is an alkyl or cycloalkyl group and R1 is NH2, NH2 or OH.  They may be obtained by subjecting an alkyl or cycloalkyl diphenyl phosphine oxide to nitration, subjecting the dinitro product obtained to reduction to form the corresponding diamino compound and converting the latter to the corresponding dihydroxy compound, the process being stopped at the stage required for the desired product, and the steps of nitration, reduction and conversion being conducted by any of the methods known for use or described in the literature.  The group R may suitably be methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, hexyl, or cyclohexyl. The nitration is suitably effected with a mixture of concentrated sulphuric acid (66 DEG Be1) and forming nitric acid and the dinitro compound may be reduced to the diamino compound by heating it under reflux for several hours with iron in the presence of concentrated hydrochloric acid (20 DEG Be1).  The diamino derivative may be converted to the dihydroxy derivative by diazotising the amino groups, e.g. by treating the diamine with nitrous acid, and then thermally decomposing the resulting diazo derivative in the presence or absence of a catalyst.  The nitrous acid may be formed in situ in the reaction mass by adding an aqueous sodium nitrite solution to an aqueous sulphuric acid solution of the diamine cooled to about 0 DEG C. and the reaction mass containing the diazo derivative is then poured into water at 60-80 DEG C. to yield the dihydroxy compound. The diamino and dihydroxy compounds can be condensed with other bifunctional molecules to give polymers (see Division C3).ALSO:Phosphine oxides of the formula: <FORM:0943317/C3/1> wherein R is an alkyl or cycloalkyl group and each R1 is NH2 or OH (see Division C2) can be condensed with bifunctional compounds to yield polymers whose chains contain phosphorus units.  Thus, methyl bis (m-amino phenyl) phosphine oxide may be condensed with dicarboxylic acids or their chlorides or with diisocyanates to give polyamides or polyureas, and methyl bis (m-hydroxyphenyl) phosphine oxide may be condensed with dicarboxylic acids or their chlorides to yield polyesters or with diisocyanates to yield polyurethanes.  Specified bifunctional compounds are adipyl chloride and toluene diisocyanate.

Abstract: 184,503. Brown, F. W. Feb. 11, 1921. Lateral-splash guards for motor vehicles, of the kind wherein an arc-shaped frame A carrying a brush of flexible material is mounted at the lower end of radial arms B to swing freely about the axle cap of the wheel, are characterized by ball- and-socket joints M, provided between the radial arms and the brush-carrying frame to allow transverse movement away from the wheel, and by pin-and-slot connections which attach the upper ends of the arms to the central bearing-ring D to allow the guard to rise vertically on meeting an obstruction. The ring D, hinged at E, has an internal flange fitting into a groove in a ring K shrunk on the axle cap, or the ring K may be formed as a roller or ball bearing. A stop N on the segment behind the arms B prevents the brush from swinging towards the wheel in its transverse movement at the ball-and-socket joints.

Title: Improvements in sols containing actinide metals
IPC: C01F17/218
Filed: 1963-02-06
Abstract: The invention comprises sols in which the particles, which are generally from 5 to 100 millimicrons in diameter, consist of an intimate mixture of one or more oxides of a rare earth (i.e. yttrium and the elements from lanthanum to lutetium in the Periodic Table), and one or more oxides of quadrivalent uranium, plutonium or an element of atomic number greater than that of plutonium.  The particles may contain 0.5 to 90, preferably 40 to 80, mole per cent of the rare earth oxide and 99.5 to 10, preferably 60 to 20, mole per cent of the other oxide.  The sol is prepared by autoclaving, at at least 100 DEG  C. under a nonoxidizing atmosphere, a freshly prepared sol of the rare earth oxide with a freshly prepared sol of the other oxide.  One or both of these sols may be prepared by peptizing the corresponding hydroxide with a non-oxidizing monobasic acid, e.g. acetic acid, or by removing the anions from a solution of a salt, e.g. chloride, of the element by electrodialysis or ion exchange. The autoclaved sol may be deionized by passing it over a mixed anioncation exchange resin.  The particles of the autoclaved sol may be separated and redispersed in deionized water.

Abstract: 1,174,400. Rotary meters. COMPAGNIE DES COMPTEURS. Feb. 2,1967 [Feb. 21, 1966] No.5170/67. Heading F1F. A rotary meter measuring the flow of fluid through a pipe 2, includes a braking turbine mounted on the same shaft 7 as an axial-flow turbine rotatable by the fluid-flow and operatively connected through bevel gearing to a totalizator 6. The axial-flow turbine comprises a plurality of peripheral blades 12 formed on a shroud 12a located in the pipe between stationary nose and tail parts 1a, 1b and the braking turbine a plurality of inwardly radially projecting paddles 15 of ovoid cross-section which co-operate with a plurality of blades 17 formed on an annular part 16 of the stationary nose part 1a. The pressure difference on the two sides of the braking turbine induces an axial thrust in opposition to the axial thrust produced by the flowing fluid on the axialflow turbine to reduce the resultant axial thrust acting on the meter to reduce friction and thus improve its operational range and permit its use without modifying its initial rating either with a fluid of a different nature, or with the same fluid under different pressure and for temperature conditions.
