Title: Improvements in the preparation of cold-swelling starch flour
IPC: A23L29/212
Filed: 1958-05-14
Abstract: A cold-swelling starch flour is made by forming an aqueous suspension of the starch, working the suspension up into a paste and drying it on a roller drier, characterized in that the paste is fed to the drier in an aerated condition.  The initial suspension or the paste can be mixed with air in various ways. Thus, air can be blown directly into the suspension, but preferably the suspension is subjected to a stirring and heating operation, for example by passing the suspension through a colloid mill.  In an example, a starch suspension in either water or skimmed milk is worked up in a colloid mill to a foamy mass and then dried on a two-roller drier operated at 4 revolutions per minute with a steam pressure of 4,5 atm. gauge and at 155 DEG C.

Title: Improvements in or relating to hydraulic tele-control systems
IPC: F15B7/00
Filed: 1942-11-05
Abstract: 561,245. Hydraulic telemotor controls ; fluid-pressure servomotors. ARMANDIAS, L. S., and ASSOCIATED MESSIER INVESTMENTS, Ltd. Nov. 5, 1942, No. 15641. [Classes 69 (ii) and 135] In a hydraulic telemotor control system, such as is used for operating ships' rudders, the receiving member R is automatically returned to midposition when the transmitting member T is in mid-position by operating liquid supplied by a hydro-pneumatic accumulator 35, Fig. 1, or 121, Fig. 4. The operating wheel 27, Fig. 1, operates a rocking beam 15 and causes movements in opposite directions of pistons 7, 8 in cylinders 1, 2 connected by pipes 5, 6 to cylinders 3, 4 fitted with . pistons 9, 10 connected by rods 13, 14 to the rocking beam 16 of the receiver. When the beam 15 is returned to mid-position, cams 45, 46 on a shaft 29 geared to the wheel 27 operate spring- closed valves to connect a pipe 38 leading from the accumulator to the upper ends of the cylinders 1, 2 which are thus brought to the same pressure and also the pressures on the pistons 9, 10 are equalized causing the beam 16 to assume a horizontal position and restore 'the receiver to midposition. In a modification, the cylinders 1, 2 are made to move relatively to pistons which are extended to the base 21 and pivotally mounted thereon. The piston rods are formed with internal bores so as to connect the cylinders 1, 2 to the pipes 5, 6, and the receiver is constructed similarly. In a further modification, Fig. 4, which has also cylinders 67, 80 in the transmitter movable relatively to pistons 66, 79 with piston rods pivoted at 77, 88, and the receiver R is similarly constructed with cylinders 92, 93 movable to operate the receiving lever 118, the sides 97, 107 of the cylinders 92, 93 not connected to the cylinders of the transmitter are filled with liquid adapted to be put under pressure from an accumulator 135 kept charged by a pump 136. The supply of liquid to the chambers 97, 107 is controlled by the pressure of the operating liquid on spring pistons in chambers 184 connected by pipes 186, 187 to the pipes 119, 120 leading from-the cylinders of the transmitter T. At a given pressure one of the spring pistons is depressed, and a further valve is operated to connect the accumulator 135 to the required chamber 97, 107, and so the operation of the wheel 91 of the transmitter is assisted hydraulically. The hydro-accumulator 121 is connected to the cylinders 65, 78 by valves 126, 127 operated by a cam 128'connected to a lever arm 74 on the shaft of the transmitting device.

Title: Determination of the oxygen activity of a bath of molten metal
IPC: C21C5/30
Filed: 1974-04-09
Abstract: 1408377 Oxygen activity of molten metal CENTRE DE RECHERCHES METALLURGIQUES CENTRUM VOOR RESEARCH IN DE METALLURGIE 9 April 1974 [9 April 1973] 15643/74 Heading GIN The oxygen activity of molten metal is determined using a device which produces electrical signals representing temperature and oxygen content by amplifying the signals and feeding them to a computer which calculates the activity and feeds the result of the calculations to a recording apparatus or a digital indicator. The activity (A) is calculated from the formula: where Ko and K are constants, E is the PD between the electrical signals and f(T) is a function of the absolute temperature of the metal which allows for temperature variations of sensor conductivity. The sensor comprises a thermocouple 1a and an oxygen sensor 1b. The thermocouple signal after correction for ambient temperature (signal from 8) is amplified at 3, sensed at 4 and converted to f(T) at 20. The difference between the sensor signals is amplified at 2 and then passed to computer 5 where the activity is calculated, the result being displayed on chart recorder 11 or on digital voltmeter 10 along with the temperature. Calibrating signals are generated by circuit 9. The measurement may be controlled by circuit 6 which detects a predetermined temperature, starts the measurement after a short period to allow the readings to settle and switches off after the temperature has dropped again.

Title: Circuit arrangements for cold cathode tubes
Inventor: KERR DAVID
IPC: H03K29/00
Filed: 1959-05-07
Abstract: 880,882. Transistor circuits. ULTRA ELECTRONICS Ltd. Feb. 26, 1960 [May 7, 1959], No. 15657/59. Class 40(6). A two-way dekatron control circuit comprises two 'transistor blocking oscillators each feeding one input of a dekatron counter and interconnected so that a pulse applied to trigger one transistor causes an output pulse to be applied to each of the two dekatron inputs in successive forward order, and a pulse applied to trigger the other transistor causes a pulse to be applied to said inputs in successive reverse order. As shown, transistors Tl and T2 and transformers W1, W2 form a pair of blocking oscillators respectively feeding the guides G1, G2 of a dekatron counter. The transistors are normally biased off. When a negative pulse is applied to terminal A, transistor T1 is rendered conductive and then rapidly cut off by the regenerative action via capacitor C1, feeding a pulse to the dekatron guide Gl. The overshoot when transistor Tl bottoms is fed to trigger transistor T2 which generates a pulse in a similar manner to feed the guide G2. Thus a pulse at terminal A adds one to the count. The overshoot from transistor T2 has no effect on transistor T1 since it is biased off by the charge on capacitor Cl. A negative pulse fed to terminal B provides a pulse on guide G2 followed by one on G1, subtracting one from the dekatron count.
