Abstract: 1,235,471. Treating gases containing entrained solid particles. CENTRAL ELECTRICITY GENERATING BOARD AND ALBRIGHT & WILSON Ltd. 14 June, 1968 [16 June, 1967; 28 Nov., 1967], Nos. 27871/ 67 and 54029/67. Heading B1R. A method of separating entrained solid particles from a gas comprises contacting the gas with a smoke precursor at a temperature sufficient to volatize the smoke precursor, cooling the gas sufficiently to produce a deliquescent dispersion or a deliquescent coating on the entrained particles form the volatilized smoke precursor, and passing the gas in the presence of water vapour through a gas/solids separator. A smoke precursor is defined as a solid, free-flowing material capable of being volatilized into a gas at an elevated temperature and which on cooling produces a deliquescent dispersion in the gas or a deliquescent coating on solidscontained in the gas. Sulphonic acid is a suitable smoke precursor and may be introduced into the hot gas either in aqueous solution or entrained in a carrier gas. The gas/solids separator is preferably an electrostatic precipitator and the amount of water vapour in the gas passed to the separator is between 4 and 15% by weight. In a modified method the smoke precursor may be volatilized into a carrier gas which is introduced with or without cooling into the gas containing the entrained solids.

Title: Tuning of musical instruments
Inventor: PHILLIPS ROBERT STEPHEN
IPC: G10H1/44
Filed: 1966-12-05
Abstract: 1,213,794. Tuning musical instruments; measuring frequencies. R. S. PHILLIPS. 5 March, 1968 [5 Dec., 1966], No. 54377/66. Heading G4A and G5J. In an apparatus for use in tuning a musical instrument, a pulse of duration proportional to the frequency of a note is derived from a signal A produced by a transducer 7 and applied to open a gate through which high frequency oscillations are applied from a generator 13 to a binary counter 14. The counter is initially set to the complement plus one of the correct count for the note by means of a note selector switch 5 and a diode matrix 17 (Fig. 4, not hown), whereby the counter is returned to zero if the instrument is in tune. Otherwise the final reading of the counter indicates the departure from correct tuning. At the completion of each count the counter reading is transferred by a monostable circuit 18 to a lamp display 6 and a meter system 8, 15. In order that the counter may function in the same frequency range for all octaves, the circuit between transducer 7 and gate 12 includes a switched divider system 4, 10 whereby between one and seven binary dividers may be introduced. A final divider 11 halves the frequency of the gate signal. The input signal to 11 triggers a monostable circuit 16 so as to operate 5 and 17 to set in the initial count before each count, whilst the output signal from 11 resets circuit 16 and triggers circuit 18. The lamp display comprises five lamps of which the centre lamp, when illuminated, indicates that the instrument is in tune, whilst the two adjacent lamps respond to a count error of between one and sixteen and the outer lamps to an error of more than sixteen.

Abstract: 1368972 Evaporation method and apparatus INTERNATIONAL BUSINESS MACHINES CORP 24 Nov 1971 [31 Dec 1970] 54512/71 Heading C7F [Also in Division H5] Capacitor discharge between a superconducting electrode 22 and super-conducting hearth 23 in a cryogenic fluid e.g. liquid helium causes material, in the hearth to be vaporized and then condensed so as to form a second material of modified structure. One side of the capacitor comprises earthed plates 10, 12 while the other plate 18 is connected through a resistor 36 to the live terminal of the battery 34. A hammer structure 24 in a plastics tube 28 is driven against the central pad of plate 18 by an alternating field in the coil 26 so as to narrow the electrode/hearth separation and causes a repeated discharge cycle. The plates, current leads and hearths within the liquid helium enclosure 30 are preferably of super-conducting material e.g. tantalum or niobium. Liquid helium enters the arc space 41 via bores 40 in the plate. The surface of the plates have an oxide layer corresponding to the plate material grown thereon. The discharge parameters are varied by means of a hearth height adjustor 20 and current frequency adjustment of the output of the A.C. source 32. A X-Y travel feature may be incorporated in the hearth Fig.2B (not shown). In examples of use of the invention, GaAs is transformed to Ga and La 2 Se 3  is transformed to La 3 Se 4 . Super-conducting electric elements of Amorphus Ga may also be formed at selected locations on a wafer.

Control switch 3 operates groups of signalling lamps 4g, 4d and warning lamp 5, for example in the direction signalling system on a vehicle (see Division G4). In the inoperative state of switch 3, transistor T2 is conducting, transistor T1 isnon-conducting, and capacitors C2, C1 are charged on operating switch 3, transistor T2 is turned off and transistor T1 becomes conducting to energize relays 1 and 2. After a period, transistor T 2  again becomes conducting, and transistor T1 is turned off and maintained blocked by discharge from capacitor C1; when the current in the base of transistor T2 is insufficient, the transistor becomes blocked, transistor T1 opens, and the cycle repeats. A further capacitor C prevents oscillations due to parasitic capacitances. Diode D dampens tensions induced by the coil of relay 1. In a modification, Fig. 2 (not shown), P-N-P transistors are used in place of N-P-N transistors and in Fig. 3 (not shown) one transistor of each type is used.

In order to mix the bristles B, B<SP>1</SP> in constant proportions in each bristle tuft, slot 76 in picker bar 22 is adjusted to gather, at different depths, sequentially from magazines 14 and 16, during each feed stroke towards tufting tool 28. The effective depth of slot 76 is limited, beneath magazine 14, by stationary vertically adjustable stock fingers 21 and, beneath magazine 16, by the position of stock bars 20. During tuft insertion, for example, of different lengths and thicknesses of bristles in a toothbrush stock I, the bars 20 are raised, by pivoting lever 90 anticlockwise about its pivot 98, to allow picker bar 22 to make its return stroke without gathering bristles from magazine 16. During the feed stroke of picker bar 22, bars 20 are lowered to a position determined by the spring-urged contact of arm 102 with the end of adjustable bolt 115. During the passage of notch 76 under the partition 18, the bristles B are packed down on to the bars 20 by the trailing end of resilient urged stripper member C.

Garments are dried in a cabinet comprising tunnels 11, 25, 26 set about three sides of a rectangle. Hot air is supplied via an airconditioning unit 27, and fan 40, at a predetermined and distinct speed for each section, to the tunnel sections through a false floor and via baffle systems so that garments are caused to billow at the centre by baffles 28, 31, 34 and at the sides by baffles 29, 30, 32, 33. The air is controlled for temperature by means of a thermometer whose reading determines the steam input to a heater, and for relative humidity by means of a wet bulb thermometer, working in a mixture of external air, and air from the tunnels, such that its temperature is below the boiling point of water, whose output governs a steam supply to the air in the cabinet. The hot air recirculates unless an upper limit of humidity is reached, when it is released from the system. The garments are passed through the cabinet on a continuous conveyer, and doors at the ends of the cabinet are opened and closed automatically for garments to pass.
