Abstract: 510,885. Automatic control systems. BANNER, E. H. W. Feb. 9, 1938, No. 4032. [Class 38 (iv)] [Also in Group XXXVI] Electromotive force.-Apparatus for measuring or recording small fluctuations from a normal alternating-current voltage comprises a meter connected in a continuous-current bridge circuit between the rectified fluctuating voltage and a source of substantially constant voltage. Shunt or series resistors can be used with the meter for giving a less sensitive range of response. In Fig. 1, a supply through transformer 1, 2 is rectified at 3, smoothed at 4, 5 and the direct-current volts are taken from a tapping on resistor 6, 7. The constant voltage source 8 is applied to resistor 9, and may include a cell 15 for standardising purposes. The sensitive voltmeter 20 is connected between the two sources and is protected by interrupters 18, 19. A barretter and limiting resistor can be connected to the main direct-current for keeping the source 8 constantly charged. Fig. 3 shows another arrangement having a barretter 22 connected to the main source, two rectifiers 3, 23 supplying the sensitive voltmeter 20. In other arrangements, the constant voltage is supplied by a neon or other gas discharge tube, and in these circuits a constant current device can also be employed. Constant voltage devices connected in opposition can be used to increase the instrument deflection due to line voltage fluctuations. The instrument can be scaled in percentage change from normal volts, and can be provided with contacts for performing known control or regulating operations.

Abstract: 1294191 Copying for scanning CROSFIELD ELECTRONICS Ltd 18 Jan 1971 [28 Jan 1970] 4147/70 Heading H4F The colour component outputs of an analysing head 26 of a colour facsimile printer are fed to a circuit 32 which identifies the combination of the colour component signals which results from flesh colours in the scanned picture and generates signals which are added to the colour component signals at 34 to correct the flesh colourings or make them appear browner in the reproduction than the original. So that similar colourings resulting from other objects are not affected by the circuit 32 a painted or cut-out mask may be used on a drum on the same axis as the drum 12 carrying the original picture 10 and reproduction 14, the signals from the scanning of the mask inhibiting the circuit 32 except when people are being scanned. In the circuit 32 variable voltages are added to the yellow and magenta signals and these signals and the cyan signal are passed to a largest signal selector and a smallest signal selector whose outputs are connected to the negative and positive inputs of a differential amplifier, the variable voltages being set so that the resulting yellow, magenta, cyan signals are equal for flesh colourings, the output from the differential amplifier then being an adjustable bias voltage applied to one of its inputs. For other colourings the output of the differential amplifier is lower, negative signals being blocked by a diode. The variable voltages may be set for different skin colourings, e.g. European and Japanese, and a mask with three colourings may be used so that the skin colourings for European and Japanese people may be differently adjusted.

Patent GB-722434-A (GB)
Title: Process for the production of hexamethylenetetramine
IPC: C07D487/18
Filed: 1952-02-18
Abstract: Hexamethylenetetramine is obtained by reacting ammonia and formaldehyde in solution in a solvent, the reaction being carried out at the boiling-point of the reaction mixture and the heat of reaction that is evolved being utilized as heat for effecting evaporation of the solvent containing the reactants.  The heat of reaction is defined as the total heat produced by the absorption and by the solution of the reactants in addition to that of the reaction proper. By selecting suitable pressure conditions, i.e. reduced or increased pressure, with, if required, the addition of another gas, the boiling-point can be fixed as required for the most favourable reaction temperature.  Specified solvents are water and alcohol.  In carrying out the reaction the reactants may be brought together as follows: (a) formaldehyde is dissolved in water or aqueous alcohol and gaseous ammonia is passed into the solution or otherwise brought into contact with the solution, e.g. in a trickling tower; (b) the ammonia is dissolved in water or aqueous alcohol and gaseous aldehyde is introduced into the ammoniacal solution; (c) gaseous ammonia and gaseous aldehyde are introduced into a solvent such as water or aqueous alcohol or into a solution containing dissolved reaction product; (d) dissolved ammonia and dissolved formaldehyde are interacted.  The process can be made continuous by proportioning the formaldehyde and ammonia by means of suitable regulating apparatus, e.g. pH-regulating apparatus, polarographs or conductivity meters. In examples: (1) a 30 per cent aqueous solution of formaldehyde at 20 DEG  C. trickles through a trickling tower and meets an ascending current of gaseous ammonia introduced at the bottom.  The pressure is adjusted to about 150 mm. of mercury corresponding to a boiling temperature of about 60 DEG  C. or to such other pressure as will enable the reaction to be carried out within the preferred temperature range of 50-70 DEG  C.  The evaporated solvent is condensed and the hexamethylenetetramine formed leaves the column as a 27 per cent aqueous solution which is then evaporated in a vacuum evaporator to form solid hexamethylenetetramine.  The ammonia added is proportioned by means of a pH regulating apparatus to a neutral outflowing solution; (2) a 27 per cent solution of hexamethylenetetramine is prepared as in (1) and is evaporated down to give a concentrated solution into which gaseous ammonia is introduced whereby the solubility of the hexamethylenetetramine is lowered and pure hexamethylenetetramine is precipitated and separated from the ammoniacal mother liquor which is again reacted with a 30 per cent formaldehyde solution at a pressure of 156 mm. of mercury, corresponding to a boiling temperature of 61 DEG  C. whereby the ammonia dissolved in the mother liquor is converted into hexamethylenetetramine.  The outgoing vapours are condensed and the solution of hexamethylenetetramine flowing out of the reaction apparatus is again introduced to yield a further quantity of hexamethylenetetramine.

Title: Improvements in and connected with Power-operated Mechanisms Fitted with Hand-operating Gear.
Inventor: PIKE FREDERIC JOHN
IPC: B63B19/00
Filed: 1917-03-28
Abstract: 116,111. Pike, F. J., and Neville, H. March 28, 1917. Mountings.-Relates to hydraulic and other fluid-pressure systems for training guns, and consists in connecting hand-gear to the control-valve lever in such a manner that on.operating the handgear, the valve-lever is so set that the gun is operated by power if power is available, while if power is not available the hand gear is free to operate the gun; further, the valve-lever can be operated independently of the hand-gear at any time. In the arrangement shown in Fig. 1, applied to operating a bulkhead door, the hand-gear is effective to control the valve-lever o only in closing the door. The hand-gear consists of a crank shaft c formed with a dog d adapted to engage a dog b on a shaft a which is geared to the door. An arm e, secured frictionally to the shaft c, can operate the valve-lever o by means of a telescopic rod k, l which is extended by a spring m. The valve-lever o is normally in the opening position, shown in dotted lines, and on operation of the hand-gear in the direction of the arrow the valvelever is moved into closing position, as shown. When the lost motion between the dogs b, d is taken up, the arm e is arrested and then slips. The frictional mounting of the arm e can be replaced by a resilient coupling or by a screw and nut. When the hand-gear is used for opening the door, the arm e is arrested by a stop f. The valve-lever o can be operated at any time independently of the hand-gear, the spring m yielding. The hand-gear may be arranged to control the valve-lever both in closing and opening the door. For this purpose, the arm e in addition to engaging the rod k, l, is coupled to the valve lever by a resilient link. The control valve described in Specification 113,675, [Class 65 (i), Door and gate operating appliances &c.], may be employed, and the system may be provided with the master valve described in Specification 113,843, [Class 65 (i), Door and gate operating appliances &c.]. For use in reversible two-main systems in which the closing position of the valve lever is at the right when main No. 1 is active and at the left when main No. 2 is active, the telescopic rod k, l is replaced by the device shown in Fig. 3. A cylinder r. in communication through a port u main No. 2, is provided with plungers q, p which are forced apart by a spring s. When main No. 2 is active, the pressure forces the plunger p away from the valvelever o, and thus prevents the valve-lever from being set in the opening position by the operation of the hand-gear.
