Title: Improvements in or relating to electric circuits for television systems
IPC: H04N7/04
Filed: 1932-06-18
Abstract: 407,951. Television. BUCKLEY, A. H., 78, Victoria Street, Queen's Park, Waverley, New South Wales, Australia. June 18, 1932, No. 14169. [Classes 40 (iii) and 40 (v).] In a television system, high-frequency oscillations produced by a thermionic valve have a portion of each oscillation suppressed, e.g. by passing them through a further valve so biassed as to transmit only a part of each oscillation, the resulting impulses being applied through delay circuits to a series of photo-electric cells on which the image is projected. The receiver comprises a thermionic distributor with delay circuits synchronised with those at the transmitter. Transmitter. Oscillations generated by the circuit 1, Fig. 1, are applied to circuit 2 in which the valve is so biassed as to pass a part only of each oscillation. The resulting impulse is led through a resistance L, microphone K, and a plurality of light-sensitive cells G, conductors H producing a delay in the passage of the impulse through each of the devices L, K, G, so that a plurality of impulses is produced from the original impulse and fed to circuits 3, 5 for transmission. The initial impulse of the plurality is made greater than the others by adjusting the valve of the resistance L. Scanning. The impulses from the terminals XX<1>, Fig. 1, are fed to terminals XX', Fig. 5, and after amplification in circuit 2, Fig. 5, are combined with oscillations from a generator 4 to produce a beat frequency controlling a fork P which controls an oscillating mirror M, Fig. 6, providing one component of scanning. The other component is provided by a motor O controlling a second oscillating mirror or the traversing of a film across a slit. The cells G are arranged in a line. Receiver. The received signals, amplified in circuit 2, Fig. 4, are applied to circuits 3, 8, 10 &c. The valve of circuit 3 is so biassed as to pass only the initial impulse of each series corresponding to the resistance L, Fig. 1, and this impulse, amplified in circuits 4, 5, is applied to circuits 9, 11 &c. over conductors including delay devices H to counteract the prohibitive bias on each of the circuits in turn, so that the loud-speaker L.S. and the neon lamps N are energized at the moment when the corresponding impulse is applied to circuits 8, 10, &c. Delay devices H' connected in series with the neon lamps and loud-speaker allow them to be energized simultaneously. The scanning device is similar to that of Figs. 5, 6, the neon lamps replacing the cells. The inductance Z, Fig. 4, is coupled to the inductance Z, Fig. 5, of the scanning system. The system may be adapted for colour reproduction by the use of suitable filters in the scanning systems. Specification 362,044 is referred to.

Title: Process and apparatus for heating viscose
IPC: D01F2/08
Filed: 1955-05-17
Abstract: <PICT:0804881/IV (a)/1> <PICT:0804881/IV (a)/2> A method of heating viscose comprises passing steam, preferably substantially dry saturated steam, continuously into a continuous stream of the viscose, both the viscose and the steam being under a sub-atmospheric pressure, and the temperature of the steam being above that of the viscose.  The viscose is initially at a temperature of about 18-22 DEG  C. and is preferably heated to a temperature of 35-45 DEG  C.; the steam is at most 15 DEG  C., and preferably 5-15 DEG  C., above the temperature of the viscose.  In a preferred embodiment, a vortex is established in the viscose and the steam is introduced by means of a vertical duct extending downwardly through the centre of the vortex so that the viscose is not in contact with the duct except at the lowest extremity. Fig. 1 is a diagrammatic view of the apparatus as a whole.  Steam jet 12 maintains a low pressure, through lines 13 and 14, in the air-tight heater 11.  Pump 16 feeds viscose to heater 11 at a constant rate, and conduit 17 passes steam from tank 18 to the heater.  Outlet 19 leads from heater 11 to a level control chamber 21, and the viscose passes thence through line 63 to a ripening zone (not shown).  Automatic control arrangements, such as 82 and 83, may be incorporated to govern the flow of steam and the pressure within the heater.  Referring now to Fig. 2 (representing the heater 11, in vertical cross-section), the viscose enters through pipe 29 which extends into the heater and just through draught tube 33.  This is a tube of diameter about one-half of that of shell 24 and is mounted coaxially as shown, supported at the bottom by notches 34 formed in a radially mounted series of baffles 36, and at the top by a series of struts 37.  A duct 38, connected to conduit 17, passes downwards through the draught tube 33, and is of diameter about one-half of that of the draught tube.  The lower end of this duct is in the same horizontal plane as that of the draught tube.  A rotary impeller 39, with blades 41, is mounted just below the duct and draught tube. When this impeller is in action, a vortex (indicated by dotted lines 49) forms in the viscose, and the steam, which is passed through duct 38, is uniformly dispersed throughout the viscose.  The impeller also acts so as to cause a vigorous vertical circulation of the viscose. Furthermore the viscose is in contact with the hot duct 38 at the lower extremity only, thus minimizing any chance of unequal ripening which may otherwise arise from non-uniform heating.  The rate of addition of the viscose, which desirably has a cellulose content of 7-8.5 per cent and an alkali content of 5.5-7 per cent, is so adjusted that fresh viscose is added at a volume rate of 1-2 per cent of the volume rate at which the viscose is circulated within the heater. Specifications 804,882 and 804,883, [Group XIII], are referred to.

Specified resins are the reaction product of an aldehyde (e.g. formaldehyde, acetaldehyde, benzaldehyde or furfuraldehyde) with urea, thiourea, aminotriazines (e.g. melamine), the products obtained by heating and decomposing dicyandiamide, and phenol.  Mixed resins, e.g. urea-melamine-formaldehyde resins and urea-thiourea-formaldehyde resins may also be used.  Specified cellulose ethers are alkyl ethers, carboxyalkyl ethers, hydroxyalkyl ethers, mixed alkyl and hydroxyalkyl ethers, mixed alkyl and carboxyalkyl ethers, and the salts of carboxyalkyl ethers which contain free hydroxyl groups.  The regenerated cellulose may be regenerated from viscose or nitrocellulose and may be dyed or pigmented.  The moulding composition may contain minor proportions of wood flour, asbestos, cotton linters, colouring materials, pigments, dyes, lubricants, plasticizing and impregnating agents, curing catalysts, starches, gums, alginates or casein.  In examples: (1) urea, formalin, hexamethylene tetramine, ammonium benzoate, chipped regenerated cellulose and alpha-cellulose are mixed below 45 DEG  C. and the mixture dried at 60-80 DEG  C.  It is then ground and may be mixed with zinc stearate, colouring materials or curing catalysts; (2) a water-soluble reaction product of melamine and formaldehyde, a water-soluble reaction product of urea and formaldehyde, regenerated cellulose and alphacellulose were mixed and dried as in example (1).
