Title: Improvements in or relating to semi-automatic mechanisms for controlling the tiltingof the drum of a concrete mixer
IPC: B28C5/18
Filed: 1959-04-30
Abstract: 850,262. Concrete mixers. ETABLISSEMENTS RICHIER. April 30, 1959 [May 10, 1958], No. 14730/59. Class 86 The drum of a concrete mixer is tilted by a worm gear driven from a constantly rotating shaft through a pair of reversing clutches, and automatically disengaged on arriving at the charging or discharging position. The drum cradle carries a worm wheel 2 rotatable by a worm 3, operated by bevel gears 7, 8, the gear 8 being fast on a hollow shaft 13. Slidable in but rotating with shaft 13 is a male double cone clutch member 14, which may engage with one or other of the female members 10, 12 geared to a shaft 9 driven by the inner engine; the interposition of the idler wheel 11 causes the members 10, 12 to rotate in opposite directions. The member 14 is engaged by movement of a hand lever 18 which shifts the shaft 16 axially by means of the fork 20 and trunnion 17. The worm wheel 2 has studs 25, 26 arranged to trip the lever 23 when the drum arrives at the charging or discharging position; this activates the shaft 19 and jack 20 through the bevel gear segments 21, 22 to shift the clutch into the vertical position.

Title: Chromatography of antibiotic solutions
Filed: 1948-06-01
Abstract: Antibiotic materials are concentrated and purified by passing a solution of the antibiotic material and associated impurities through a column of an adsorbent on which the antibiotic material is not strongly adsorbed and on which at least one of the impurities is more strongly adsorbed, the volume of the solution being such that the amount of antibiotic material therein is greatly in excess of that required to saturate the column therewith.  The effluent from the column is collected in fractions and the antibiotic material may be recovered from the fractions rich therein, i.e. those collected between the time when the antibiotic material begins to appear in the effluent and the time when the more strongly adsorbed impurity or impurities begin(s) to appear.  An example describes the application of the process to the purification of streptomycin, especially from histamine, using a synthetic inorganic base-exchange material as the adsorbent.  Specification 14572/44 (as open to inspection under Sect. 91) is referred to.  Reference has been directed by the Comptroller to Specification 14572/44 (as open to inspection under Sect. 91).

Title: Improvements relating to frequency and phase modulation
IPC: G01S1/02
Filed: 1945-06-11
Abstract: 595,168. Frequency modulation; radio navigation. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. June 11, 1945, No. 14800. [Class 40 (v)] An arrangement for demodulating frequency- or phase-modulated carrier waves comprises means for transferring the modulation to a. carrier wave of stable frequency and a known frequency or phase discriminator operating at the stable frequency. A frequency-modulated wave from source 1 with mean frequency f, which may be the I.F. of a superheterodyne receiver, is applied to a modulator 3 together with a wave of stable frequency F from source 2. One of the sidebands f - F or f + F in the output of modulator 3 is selected by filter 4 and fed to a second modulator 5 together with the incoming wave f. The output F from modulator 5 is fed through a filter 6 to a discriminator of known type designed to operate at the fixed mean frequency F. The delay time of filter 4, which has a linear phase-shiftfrequency characteristic, may be chosen so as to encourage modulation at a wanted frequency or to suppress modulation at an unwanted frequency. The discriminator 7 is preferably of the type in which the signal is fed to two detectors in parallel by one path and in pushpull by a path having a different transit time (Fig. 3, not shown). The arrangement may be used in a radio D.F. system of the type described in Specifications 591,668 and 594,530, in which the received signal has sudden positive or negative phase shifts which may have any value up to more than 360 degrees. The delay time in filter 4 is made equal to the interval between the jumps in phase, and the output of filter 6 is a signal having sudden phase shifts equal to the difference between two successive phase jumps in the received signal. The maximum phase shift is thus reduced to a value which the discriminator can handle satisfactorily. Specification 534,955 also is referred to.

Title: Self-decoding color television apparatus
IPC: H04N9/26
Filed: 1957-05-14
Abstract: 866,569. Colour television. CHROMATIC TELEVISION LABORATORIES Inc. May 14, 1957 [June 11, 1956], No. 15221/57. Class 40(3) Relates to the reproduction of N.T.S.C. colour signals by means of a single gun cathoderay tube of the type having a line phosphor screen and incorporating post-deflection switching grids for directing the beam on to the respective phosphors. In accordance with the invention the video signal comprising both the luminance component and chrominance subcarrier is applied directly to modulate the tube beam (certain amplitude modifications of the components being effected first, see below) whilst the switching grids are controlled in predetermined phase at subcarrier frequency to cause the beam to execute a cyclic scan of a group of three phosphors, a characteristic feature of the invention being the blanking of the beam during the portion of the cycle so that one of the phosphors is not traversed twice. This feature is illustrated in Fig. 8 which also shows the phase relationship of the cyclic scan with respect to the synchronizing burst and subcarrier. The line scan is assumed to be in the direction of the phosphors and centred on the blue phosphor. Blanking occupies the phase position 162-198 degrees when the beam makes the second reverse traverse of the blue phosphor. In one embodiment the amplitude modification of the video components comprises boosting the chrominance subcarrier to a level 1À37 times that at which it is received. The Specification includes a detailed discussion, Figs. 10a-10g, of the accuracy of colour reproduction obtained. In a second embodiment, a further modification is effected in that the amplitude of the B-Y component of the subcarrier is accentuated relative to the R-Y component. This leads to more accurate colour reproduction which is discussed with reference to Figs. 11a-11f (not shown). It is stated that certain colour imperfections may be corrected by adjustment of the phase of the cyclic scan imparted by the switching grids. Reference is made to scanning the phosphors in directions other than along their length. The Specification includes detailed circuits for carrying out the invention, the techniques involved being, in general, conventional. The circuit for producing the blanking signal, Fig. 5 (not shown), comprises means for passing a signal from the local subcarrier oscillator through an adjustable tapped delay line, so as to permit the production of a wave of any desired phase, followed by a clipping stage for producing an output in response to the positive peak of the wave. The circuit for boosting the chrominance subcarrier, Figs. 2 and 3 (not shown), comprises a video amplifier incorporating a double tuned circuit resonant at the subcarrier frequency and provided with adjustable damping resistors. The circuit for accentuating the B-Y component of the subcarrier relative to the R-Y component may comprise a so-called elliptical amplifier.

Abstract: 1,023,026. Induction flow meters. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 7, 1964 [April 18, 1963], No. 15310/63. Heading G1N. The rate of flow of an electrically conducting material is determined by inducing a travelling magnetic field across the flowing material such that the direction of travel is aligned with that of the flow of the material, and adjusting the speed of the travelling field to match that of the flowing material. A rotating field is induced in a circular path of flowing material, which might be one turn of a helical duct carrying a liquid metal coolant in a nuclear reactor, by three-phase windings 12 energized by a three phase generator 14 the speed of which can be adjusted, and the voltages induced in windings 17 which are 90 degrees offset from windings 12 are applied to a meter 22 via a receiver 19 driven at the same speed as the generator by a common motor 16. The motor speed is indicative of the speed of flow when the dynamic voltage in the meter 22 is zero. The invention can be applied to a linearly moving strip.
