Abstract: 1,064,346. Classifying solids. LES ATELIERS REUNIS BROYEURS FORPLEX and P. R. HIPPERT. May 20, 1965 [May 22, 1964], No. 21497/65. Heading B2H and B2P. Material to be classified is introduced in suspension in air through a tangential inlet 2 into the casing 1 of a classifier and is braked and de-agglomerated as it passes radially inwardly through a crown-like device 24 which is constituted by vanes 27 mounted between annular members 25, 26 and which surrounds a rotor 3, the material being then subjected to the combined action of centrifugal force exerted by the rotor and of centripetal force due to suction created by a fan connected to a pipe 7 which has its inlet opening adjacent the centre of the rotor for collecting the relatively fine particles which pass through the rotor due to the pull exerted on them by the fan suction being greater. The relatively coarse particles, which are thrown out of the rotor due to the action of centrifugal force on them being greater, pass via a gap 28 defined by the lower annular member 25 of the crown-like device and a stationary diaphragm 15 arranged under the rotor and enter an annular discharge chamber 16 which communicates with a hopper 20 fitted with a rotary discharge valve 22. Classification is improved by supplementary air introduced via a pipe 18 into the chamber 16 and flowing, as indicated by the arrows f, through the gap 28 in counter-current to the flow of relatively coarse particles. The annular members 25, 26 of the crown-like device 24 may be in the form of rings or, as shown in Fig. 1, of cheek plates. The device 24 may be replaced by one having vanes of different width and profile, Figs. 3-5 (not shown) to suit requirements. In a modification, Fig. 6 (not shown), a ring (32) is secured to the underside of the bottom disc 5 of the rotor to project from the rotor. The outer diameter of the ring (32) is chosen according to the distance it is desired to offset the position of the gap 28 radially outwardly, the width of the crown-like device 24 being reduced accordingly. The classifier may be used in conjunction with a crusher for the material, the coarse particles being returned there to be further reduced in size.

Abstract: 1,138,566. Music teaching devices; chord indicating device. C. F. GULLICKSON. 9 May, 1967 [17 May, 1966], No. 21604/67. Headings G5C and G5X. [Also in Divisions H1 and H2] In a musical chord indicating device selection of any particular root note in the musical scale, by means of root note type selectors 52, and selection of any particular chord type, by means of chord type selectors 53, results in the notes forming the selected chord which are harmoniously related to the selected root note being indicated by an indicating light assembly (Figs. 1 and 2, not shown). The root note type selectors 52 comprise shafts 55, which may be of brass, with upstanding contact fingers 91 for electrically contacting contacts 86 arranged on four rotatable rotors 58, 59, 60, 61. The chord type selectors 53 comprise insulating shafts 57 and pins 64 which are positioned to engage arms 65 extending from the rotors. On depression of a chord type selector 53 the pins 64 cause such rotors as have co-operably positioned arms 65 to be rotated from a first position to either a second or a third position in which, on depression of a root note type selector 52, certain of the contacts 86 on the rotors contact the fingers 91 to close electrical circuits (Figs. 7 and 7a, not shown), to appropriate ones of the light bulbs 20, whereby the lighted bulbs, located above their associated keys on the keyboard of a piano, organ or other keyboard instrument, indicate that their associated notes form the type of chord selected and are harmoniously related to the selected root note. The indicating light assembly may be positioned with its bulbs above the notes of a bass octave, and the selector knobs above the notes of a treble octave, but the system may extend over more than an octave. Each shaft 57 of the chord type selectors has a latch 70 which co-operates with a pivoted arm 73 such that a depressed selector is held in its depressed position unless and until another chord type selector is depressed, in which case the selector previously depressed is released and it and the rotors returned to their normal positions under the action of a coil spring 80. A battery power source may be included. Power from the source is fed to a bus-bar 99 to which each root note type selector shaft is connected by a lead 98. The rotor contacts 86 are connected via leads 87 to bus-bars 88, then to the end caps of light bulb sockets 27 and back to the other side of the source. Indices located on or adjacent the selector knobs indicate the chord type produced by each chord type selector and the root note each root note type selector is associated with. Indices may also be located adjacent the light bulbs to indicate the note to which each bulb refers if the bulbs are not mounted above their notes.

Title: Improvements in or relating to hair waving appliances
IPC: A45D4/12
Filed: 1931-07-30
Abstract: 377,815. Hair-waving appliances. WADE, H., 111, Hatton Garden, London.- (Shelton-Jancke Corporation; 525, Main Street, East Orange, New Jersey, U.S.A.) July 30, 1931, No. 21822. [Class 131.] An electric heater for hair-waving comprises an electric resistance unit of thin metal foil insulated by sheet material so that the whole can be bent to surround a curl or the like. The heater is combined or used with the usual laminated hair-waving pads. In one construction the metal foil 24 is furnished with terminals 22 and wrapped in a folded sheet of asbestos fibre 25, 26. A folded sheet of aluminium foil 28, 29 surrounds the fibre and is, in turn, surrounded by a folded sheet 31 of parchment or other impervious material. Finally one or more layers 34 of cotton, flannel, or other absorbent material is placed on the side of the appliance adjacent to the scalp when in use. In a modification, all the folds of the doublesheets are at one end of the pad, and one of the' metal layers is arranged outside the parchment layer, being passed through a slit in the parchment for this purpose. The parchment sheets: are longer than the foil and asbestos sheets in order to increase the area of the pad and oneterminal projects rearwardly instead of laterally. In another modification the heater is preformed in a circular shape to surround a lock of hair. In another modification the layers I<1>, Fig. 23, of absorbent material are formed separately and the heater A<1> is applied thereto, the combined heater and pad then being bent round andclipped on to a lock of hair as shown. Other constructions are shown in which the laminated pad, as distinct from the heater, is formed separately or is detachable so as to be thrown away after use, while the heater is re-used with a fresh pad.

Title: Improvements in or relating to voltage control and rectifying systems
IPC: B03C3/66
Filed: 1955-07-28
Abstract: 783,818. Rectifying; automatic voltage control systems. RESEARCH CORPORATION. July 28, 1955 [Aug. 23, 1954], No. 21830/55. Classes 38 (2) and 38 (4). A load such as an electrostatic precipitator is supplied with D.C. from an A.C. source through a transformer, the circuit on the primary side of which is so arranged that the voltages of alternate half-cycles of the supply may be separately controlled. In a system for supplying two precipitates 21a, 21b through four rectifiers of which two are 23a, 23b, on the secondary side of transformer 22, a rectifier 29 in series with variable resistor 27, shunted by variable resistor 26, is connected in series with the transformer primary winding. The impedances to the primary current have different values in opposite directions, so that with switch S2 open, precipitators 21a, 21b receive trains of unidirectional half-waves of voltage of different values. With switch S2 closed both precipitators receive similar fully rectified voltage comprising half-waves of alternating values. The values of the two half-waves may be separately varied by altering the values of resistors 26, 27 and of a ballast resistor 28. Two of the rectifiers on the secondary side may be omitted if a centre-tapped secondary winding is used, Fig. 3 (not shown), and the loads may comprise separate charging and precipitator sections, Figs. 4, 7 (not shown). If two capacitors, C1, C2, each in series with an appropriately poled rectifier, 53a, 53b, are connected across the secondary winding, three loads may be supplied, 51b1, 51b2, across the capacitors separately and 51a across the capacitors in series, Fig. 5. The two voltages may be automatically controlled by separate arcing control regulators 710a, 711a, 712a and 710b, 711b, 712b which may be such as are described in Specifications 706,929, 723,058 and 740,394. The high voltage is controlled by voltage regulator 713, and the low voltage by shunt resistor 76, Fig. 7. The controlling resistors may be replaced by variable transformers or induction regulators, manually or automatically controlled, Figs. 8, 9 (not shown). Valves, copper oxide, selenium or mechanical rectifiers may be used on the primary side. If only one load is supplied with half-waves of one voltage, the arrangement results in lowered peak voltage across the primary rectifier, and the transformer, Fig. 1 (not shown).

Abstract: 1,069,074. Valve and transistor oscillator circuits. PLESSEY-U.K. Ltd. Aug. 28, 1964 [May 31, 1963], No. 21878/63. Headings H3T and H3F. An arrangement for driving a sonic or ultrasonic transducer comprises an oscillator and a power output stage, there being a feedback path from the output stage such that the frequency of the oscillator follows the resonant frequency of the transducer. Valves V1, V2 are cross-coupled to act as a multivibrator, but the circuit comprises additional phaseshifting elements including variable resistor VFC. Transducer T is driven via power output stage V3 and inductor I; feedback via (i) the anode to grid capacity of this valve and capacitor C5 and also (ii) stray capacitive coupling between the transducer, output valve, inductor I and the oscillator cause the frequency of oscillation to lock on to that of the transducer. In a modification, the oscillator is of the phaseshift type and is frequency-modulated at 50 c.p.s. by injecting part of the heater supply into the R.C. coupling network (Fig. 2, not shown), so that the frequency is swept over a small range until the transducer frequency is reached, whereupon locking occurs. It is stated in the Specification that semi-conductor devices may be used instead of valves.

Abstract: 517,530. Water gas plant. GAS LIGHT & COKE CO., HAFFNER, A. E., and PEXTON, S. July 23, 1938, Nos. 21923 and 34524. [Classes 55 (i) and 55 (ii)] Water gas produced by the intermittent method is enriched with hydrogen by passing the mixture of water gas and steam from the generator through a contact chamber containing iron oxide at 450‹-600‹C., whereby the carbon monoxide and steam are converted to carbon dioxide and hydrogen, the carbon dioxide being subsequently removed. An auxiliary steam superheater for supplying extra steam to the contact chamber may be used. In the earlier part of the blow, in a plant for up and down running, the blow gases from the generator 1 are passed through the auxiliary steam superheater 20 for burning with air admitted at 12, and then through the CO2 absorption chamber 19 for combustion with air admitted at 23 the absorbing material being thereby regenerated, the blow gases then passing as usual through the carburettor 2, superheater'3, waste-heat boiler 5 to the stack 17. The remainder of the blow goes through 1-20-2-3-5, the chamber 19 being by-passed. The latter is cooled from 800‹C. to between 450‹C. and 600‹C. by continued admission of air through 23. The run comprises up-down- and up-running by steam appropriately admitted at 7 and 8, the resulting gases in each case passing through the pipe 26 to the contact chamber and then through the absorption chamber before proceeding as usual to the carburettor, superheater and water seal 4. Extra steam may be supplied to the contact chamber from the superheater 20 through pipe 31. The contact chamber is kept at 450‹-600‹C. The catalyst may be iron oxide or iron oxide with chromium oxide in the proportion of 100 parts to 7 parts respectively. The absorption material may be Mgo or alkaline earth oxides or mixtures thereof. In a modification, the run comprises up, back-and up-running, the back-run resulting gases from the generator being also passed through the chambers 18, 19 as before. The gas may be used as synthesis gas or mixed with coal gas. Specification 195,798, [Class 55 (i)], is referred to.
