Patent GB-834306-A (GB)
Title: Process for obtaining hydrogen having an increased deuterium content
IPC: B01J23/38
Filed: 1957-04-30
Abstract: Deuterium-poor hydrogen from the cold column of the hot and cold column concentration system of the parent Specification is further depleted in D by passage in sequence through a further cold column and hot column forming a stripping system, while water passes in countercurrent first through the hot column then through the cold, and part of the hydrogen from the cold column of the stripping system is withdrawn for use in, say, hydrogenation, while the remainder has the D content increased to that of "natural" hydrogen in the stripping hot column before recycle to the hot column of the concentration system.  Fresh H2 is added to the circulation to make up for that withdrawn.  The parent Specification discloses a process for the production of D-enriched H2O or H2 by passing H2 and liquid H2O in countercurrent at elevated pressure in the presence of a catalyst in sequence through two columns maintained at different temperatures forming a concentration system.  One-third of the D-rich H2 leaving the concentration hot column may be passed to a second hot and cold column concentration system for further enrichment, whence D-poor H2 is returned to the concentration cold column.  The water circulations of the concentration and stripping systems may be combined into a single closed circulation.  Heat exchange may be provided between the liquid and gas at different temperatures, preferably in like phases.  The catalyst may be a dispersion, or colloidal solution, in the liquid phase.  The corresponding columns of the stripping and concentration systems may be at the same temperature and pressure.

Title: Improvements in or relating to circuit arrangements for safeguarding transistors
IPC: H03G11/02
Filed: 1960-04-20
Abstract: 928,584. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 20, 1960 [April 23, 1959], No. 13837/60. Class 38 (4). [Also in Group XL (c)] Junction transistors connected as cascaded emitter followers in a voltage stabilizer are protected from an excessive collector voltage supply by connecting a Zener diode between collector and base of the first transistor. The voltage stabilizer shown comprises input terminals 10 for the unregulated supply and output terminals 11 for the regulated supply. A portion of the output voltage derived from a potentiometer 16 is compared in a comparator 14, 15 with the voltage developed across a Zener diode circuit 12. The resulting variations at the collector of transistor 15 are fed through emitter follower stages 18, 19 and 20 to control transistors 21, 22 &c. connected in series with the supply so as to stabilize the output voltage. An excess input voltage will cause the Zener diode 30 to break down and so protect the transistor 18 by limiting the collector base voltage. Transistors 19-22 being connected in the emitter follower fashion to transistor 18 are also protected against over voltage. Transistors 13 and 14 are protected against the over voltage by providing a series transistor 23 in their common collector circuit. Excessive rise in voltage across terminals 10 will cause potentiometer 25 to apply a sufficient voltage to the emitter of transistor 13 to cut the transistor off. The voltages then applied by potentiometers 25 and 24 to transistors 14 and 23 are such that the maximum permissible collector base voltage of transistors 13 and 14 is not exceeded. A capacitor 31 is provided to prevent oscillation in the circuit.

Title: Frequency synthesiser
IPC: H03L7/197
Filed: 1974-03-29
Abstract: 1447418 Automatic frequency control MULLARD Ltd 29 March 1974 13997/74 Heading H3A In a frequency synthesizer of the phase locked loop type, the phase of a variable frequency oscillator output is compared with that of a reference clock generator after frequency reduction by an adjustable accumulator whose residue is converted in a D/A converter to produce a signal which is balanced against the phase comparator output to compensate for irregularities in the pulse repetition rate of one of the phase comparator inputs. In one embodiment, Fig. 3, the divided down output of the VFO and the clock pulse generator CPG are compared in phase comparator PC to produce an output which is applied to one input of a summer ASD whose output is the control signal for the VFO. The output from the clock pulse generator is also fed via a programmable multiplier RM and a counter type divider D1 to a circuit PS which inhibits a pulse from the VFO each time a pulse is produced at the output of divider D1, so that the output frequency FD from the programmable divider PRD is equal to that from divider D2. The remainder signal in divider D1 is fed to the digital/analogue converter which provides a second input to the summer ASD. The multiplier RM and divider D1 may be replaced by a single device which may receive its input from the output of divider PRD, Fig. 2 (not shown), or which may be connected in place of divider D2, Fig. 1 (not shown). In this last mentioned arrangement the circuit PS is omitted.

Abstract: 119,508. Fagard, J. Sept. 29, 1917. Spray carburcttors.-In carburettors such as described in Specifications 103,627 and 105,309. comprising a main nozzle fed from the float chamber, and an auxiliarv nozzle fed from a chamber or well open to the atmosphere and supplied from the float chamber preferably through an upstanding tube or passage, the aperture through which the well or chamber communicates with the atmosphere is of restricted dimensions and may be controlled. This ensures that, at high speed, a vacuum will be produced in the well or chamber sufficient to produce a flow of fuel thereinto and bring the auxiliary nozzle, which is usually employed for accelerating, into action again to maintain the mixture strength. The auxiliary nozzle g may surround the main nozzle a, or may enter the mixing chamber at right-angles thereto. The aperture may be controlled either manually or by a barometric device. The vertical tube is shown at e and the well at d. To ensure that the chamber d becomes emptied, and the nozzle g goes out of action at medium speeds, a restriction may be placed in the passage c between the float chamber and well or, for the same purpose, the top of the tube e may be above the normal fuel level. According to the Provisional Specification, the well or chamber may communicate with the induction pipe, and the main nozzle may be supplied therefrom.

Title: Improved anti-rolling device for automobiles and other self propelled vehicles
IPC: B60G17/015
Filed: 1934-05-10
Abstract: 432,382. Vehicle spring-suspensions. MORRIS, J. N., 63B, Islington Row, Birming- ham. May 10, 1934, No. 14126. [Class 108 (ii)] In an arrangement for preventing canting of a motor-vehicle body, e.g. in negotiating curves, one or more pairs of wheels a are suspended by means of torsion rods d having fluid-controlled anchorages, the flow of fluid to and from such anchorages being regulated by centrifugally actuated operating means. As shown, each anchorage comprises a cylindrical casing or stator f, Figs. 1 and 3, having a series of fixed internal vanes g alternating with a corresponding series of vanes h on a rotor e to which the ends of the torsion rods d are secured. One set of compartments thus formed communicates by parts 15 with an annular chamber 13, Fig. 2, and the other set by ports 16 with a concentric chamber 14, pipes y, z, leading from these chambers to a valve casing x, Fig. 4, in which is arranged a slide valve 7 adapted normally to obstruct the pipes y, z, and allow a flow only by inlet and outlet pipes w. These pipes w are arranged in a fluid circuit comprising a sump u, suction pipe v, pump t, pipes wand valve casing x. When the valve 7 is displaced by pressure exerted upon an operating piston 12, flow is permitted through the casing f and pipes y, z, in the appropriate direction, one pipe serving as a flow and the other as a return pipe to the valve casing x. To control the position of the piston 12 an auxiliary fluid circuit is provided comprising the sump u, suction pipe 4, pump 3, supply pipe 5, and valve casing 6, the regulating valve 6 being associated with two pipes admitting fluid to the upper or lower sides of the piston 12. Actuation of the valve 6 is effected by means of a weight q slidingly mounted on a rod r under the control of centralizing springs s and provided with an upstanding pin p which in turn actuates a lever n and valve lever o. One end of the lever n is attached at m to one of two transverse levers k, l, that interconnect plates i mounted on the rotor members e on opposite sides of the vehicle. The effect of this arrangement is that after a certain quantity of fluid, owing to the displacement of the weight q, has been admitted to the anchorages f, the levers l, n restore the valve o to its normal position and prevent admission of further fluid to the anchorages ; also, as soon as weight q returns to its normal position, a flow of fluid in the opposite direction is induced in the anchorages, and both the rotors e and levers k, l, n are again centralized.
