Title: Improvements in or relating to electrical remote control devices
IPC: G05D3/14
Filed: 1942-06-25
Abstract: 558,953. Electric control systems. RUBERY OWEN MESSIER, Ltd., ARNOT, A., and CONWAY, H.G. June 25,1942, Nos. 8750 and 17389. [Class 40 (i)] In a system employing two automatically balanced Wheatstone bridges for coarse and fine adjustment, the potentiometers being variable in steps rather than continuously, the bridges are brought into action in succession by a relay which operates in series with the out-ofbalance relay of the coarse adjustment bridge and disconnects the out-of-balance relay of the fine adjustment bridge. The arrangement may be extended to bring three or more bridges into action in turn. In one construction, the transmitter, Fig. 1, comprises two commutators 19, 26 mounted on shafts 17, 38 and engaged by fixed brushes 20, 27, the segments of each commutators being connected to tappings on a potentiometer. The shaft 17 is driven through gearing 15, 16 by a controlling arm 14, and the shaft 38 is driven one step for each revolution of the shaft 17 by means of a pawl 23 and slotted disc 24. The receiver is similarly constructed, except that the shaft corresponding to 17 is driven by a motor 60 and is coupled to an output shaft. The motor 60 is connected up for rotation in either direction by the out-of-balance relays 75, 87, Fig. 3, and a further relay 90 prevents the operation of relay 75 at the same time as relay 87. In another construction, Fig. 5, the commutators 119, 126 are integrally combined in the form of a drum, one comprising longitudinal segments 133, 134 engaged by a fixed brush 120 and the other comprising segments extending circumferentially and separated by a helical strip of insulation 145 and blocks 146, these segments being engaged by a fixed brush 127. The drum is threaded internally so that when rotated through gearing 107, 106 it runs along the screw shaft 104, one revolution of the commutator 119 corresponding to one step of the commutator 126. Specification 506,032 is referred to.

Title: Improvements in or relating to systems of television in colours
IPC: H04N11/08
Filed: 1952-04-17
Abstract: 711,880. Colour television. RADIO-INDUSTRIE. April 17, 1952 [April 17, 1951], No. 9714/52. Class 40 (3) A three-colour line-sequential colour television employs four-fold interlacing of the scanning lines ; thus in the first partial frame I, Fig. 2, successive lines are scanned in a sequence red, blue, green, in the second partial frame II successive lines are scanned in the same order with, however, red lines displaced by 1¢ lines of the partial frames, in the third partial frame III the red lines are again displaced by a further line of the partial frames, and in the fourth partial frame IV, the red lines are displaced by a further 1¢ lines of the partial frames, while when returning to the first partial frame a further displacement of 2“ lines takes place. The transmitter comprises three camera tubes 1, 2, 3 rendered respectively responsive to red, blue and green partial images by means of filters 4, 5 and 6. Switching potentials developed in a circuit 12 controlled from the time-base 13 are applied to gating circuits 14, 15 and 16 to render them successively operative at line frequency to pass the video signal outputs of the respective camera tubes to an output circuit. The receiver, Fig. 10 (not shown), comprises three cathode-ray tubes having associated colour filters and means for optically combing the pictures produced on the screens, the incoming video signal being switched in sequence at line frequency, by means of gating circuits similar to those shown at the transmitter, to the three cathode-ray tubes. It is arranged that each partial frame commences with a red line ; to achieve this it will be seen that corresponding synchronizing signals must be delayed in succession by 1¢, ¥, 1¢ and 2“ lines of the partial fields, this being done by a "slipping" process involving the increase or decrease of the line period during the frame blanking intervals. The transmitter comprises a pulse generator operating at eight times the normal line frequency, the normal line-synchronizing pulses being derived by a frequency divider dividing by eight an input taken from the pulse generator. However, during each frame blanking period this frequency divider is rendered inoperative and is effectively replaced by an auxiliary divider having a division ratio of either nine or seven. By means of control signals generated by suitable counting circuits this latter divider remains operative for periods respectively corresponding to 12, 6, 12 and 18 pulses from the pulse generator during successive frame blanking intervals ; after this the auxiliary divider is cut off and the first divider rendered operative. Thus a displacement of the line synchronizing pulses by 1¢, ¥, 1¢ and 2“ lines in successive frame blanking intervals is effected.

Abstract: 569,253. Tobacco. AMERICAN MACHINE & FOUNDRY CO. June 17, 1943, No. 9777. Convention date, June 11, 1942. [Class 130] A method of treating tobacco consists in applying to the tobacco a solution or sol of finely-divided tobacco particles wholly or largely of substantially colloid size to form a coating. Tobacco or tobacco waste is reduced by dry or wet grinding, e.g. in a ball mill, to a colloidal state and mixed with water to form a slurry or suspension. This may be subjected to heat treatment at atmospheric or higher pressure in an autoclave or other apparatus to hydrate and swell the finer particles. The treatment may be effected at normal atmospheric pressure by heating in a reaction flask connected to a reflux condenser. During heating, the liquid may be agitated by shaking or stirring or by bubbling steam through it. The resulting mixture may be sprayed on tobacco leaves or leaf portions on a conveyer belt 1, Fig. 1, by nozzles 2 connected to a tank 5 under pressure. Leaves &c. dropping from the conveyer 1 are inverted by a guide 8 and fall on to a conveyer 9, when they are again sprayed by nozzles 10. In a modification, the mixture is sprayed on tobacco tumbled over in the interior of a revolving drum of the type normally used in " casing " shredded tobacco for cigarettes. The coated tobacco may be stored for 24 or 48 hours before making into cigarettes &c.

Abstract: 1,253,730. Photo-electric analysis. SHERWOOD MEDICAL INDUSTRIES Inc. Feb. 24, 1969 [March 4, 1968], No. 9796/69. Heading G1A. In a system generating an electrical signal representative of a characteristic being analyzed means are provided for continuously calculating the instantaneous rate at which a factor related non-linearly to the characteristic is changing. The system may include a circuit formed only of linear functioning elements i.e. elements in which the input and output are linearly related. The readout arrangement for a spectrometer in which a prism is rotated to present different wavelengths to a photo-cell, includes a currentto-voltage converting operational amplifier with feedback, an operational amplifier 85, Fig. 4 which serves as an inverter, and a servo loop including a servo amplifier 50 controlling the poles of a shaded pole motor 100, 101, 103 providing mechanical drive to an indicator 40 which may be an indicator recorder and may be digital. The arrangement includes a ganged multiposition switch whereby transmittance, optical density, and chemical concentration or rate of change of chemical concentration of the solution being analyzed may be read. A varistor 140 is switchable into the photodetector output circuit to provide the log 10  1/T for optical density and the concentration is derived from the optical density by a multiplication by a factor which is adjustable by a potentiometer 151. The rate of change of concentration is determined in a differentiating circuit comprising an operational amplifier 93 capacitor 160 and resistor 144 and when in use, the detector output is integrated to suppress the effect of unwanted pulses means also being provided to buck out dark current. The shaded pole motor drives also a wiper on a potentiometer 111 to provide feedback to the amplifier 50 whereby the motor is driven to obtain a null. The shaded poles are effective in opposite directions and are controlled by FETs to control the rotation of the armature 103, one pole providing a continuous drive in one direction and the other tending by driving at intervals in the other direction to apply braking. A response control circuit 120 may be provided to prevent hunting by controlling the motor speed on the basis of the time of null rather than by the magnitude of the off null signal. Arrangements may be incorporated to blank out or offset from the measurement or rate of chemical activity which may be due to a catalyst.
