Title: Improvements in or relating to hydroelectric machines
IPC: F03B15/00
Filed: 1963-11-12
Abstract: 1,026,569. Automatic control systems. DOMINION ENGINEERING WORKS Ltd. Nov. 12, 1963 [Nov. 20,1962 J, No. 44670/63. Heading G3R. [Also in Divisions Fl and H2]. The torque ratio of the rotating elements of a contra-rotating hydroelectric machine is maintained at a required value by an automatic control system. As shown, contra-rotating water wheels 1 and 2, which may constitute a turbine or pump impeller, in a water passage 4 are connected by concentric shafts 6, 5 to rotors 9,11 associated  with armature windings 14 and 15, the currents in which are functions of the torque in the wheels 1. and 2 respectively. These currents are measured in a conventional comparator 18 the output from which is applied by way of an amplifier 19 and a governor 20 to control a pitch changing mechanism 17 for the wheel 2. Any deviation from a desired torque ratio results in a corrective change in the pitch of wheel 2 to re-establish the ratio. The  torque-responsive input signals for comparator  18. may be derived from strain gauges associated  with the shafts 5 and 6.

In a mechanical press the actuating mechanism for the movable upper platen comprises a crank and connecting rod mechanism and an eccentric device both operated by jacks, the latter effecting the movement through the minor effective part of the platen stroke and the former at least the return movement through the major part of the platen stroke. As described the press comprises a lower fixed platen 8, Fig. 3, and an upper platen 7 movable between guides 3 by an actuating mechanism including two pairs of crank and connecting rod mechanisms 28, 23 (one on each side of the press) actuated by a rack and pinion gearing 32, 31 controlled by a single-acting jack. The connecting rod is associated with an eccentric device 9, 25 which imparts an additional movement to the connecting rod and is operated by a doublearmed lever 11, Fig. 2 (not shown), rocked by jacks (16) and (17). The double-armed lever may be replaced by a single-armed lever located between two jacks. In other examples the eccentric device co-operates with the crank arm. The single-acting jack with rack and pinion drive may be replaced by a double-acting jack.

Abstract: 1,200,091. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. 6 Oct., 1967 [1 Oct., 1966], No. 45748/67. Heading H1K. A method of making a semi-conductor device comprises defining an area 13 on the surface of a semi-conductor body 11 by means of a mask 12, diffusing an impurity into this area to produce a first diffused zone 14, then defining on the body surface a second area 15 which includes at least part of the first area and diffusing a weaker concentration of a second impurity, of opposite conductivity type and of higher value diffusion coefficient, to form a second zone 16. The impurities are so chosen and the second diffusion carried out at such a temperature and for such a time that the depth of the second zone 16 is greater than the final depth of the first zone 14. For an NPN device as shown in the Figures, the first impurity is arsenic, bismuth, antimony, or phosphorus with boron, aluminium, gallium or indium as the second impurity, or for a PNP device, starting with a P-type body, if indium or thallium be used as the first impurity phosphorus is used as the second. The semiconductor body may be silicon, germanium or a group III, V or group II, VI compound. The completed device is covered with a protective film and provided with contact electrodes.

Title: Binary-decimal converters

Abstract: 1,138,559. Binary-decimal converter. SIEMENS A.G. 6 Oct., 1967 [25 Oct., 1966], No. 45927/67. Heading G4A. A binary-decimal converter comprises computing logic circuits by which a binary number can be divided by ten, in binary form, continually in such a manner that after the first division subsequent divisions will be carried out upon the successive quotients, and storage means for storing the remainders resulting from the division, the remainder being the binary coded decimal digits required. The binary numbers are held in a circulating store U1, e.g. operating on a magnetostriction basis and are fed in series, most significant digit first to a set of stores Sp each holding one bit and logic units L. If the logic units determine that the bits about to be read in to the stores form a number less than 10 then a " 0 " is produced at E* and the number is shifted by one bit. If the bits form a number equal to or greater than ten then a " 1 " is produced at E* and ten or 1010 is subtracted from the bits, e.g. if bits ABCDE are 11010 then E* becomes 1 and A*B*C*D*E* becomes 10001 as in table 3 where 1011100110 or 742 is divided by ten. The resulting E* is attached to the end of the binary number. This process is repeated in the manner of the division operation shown in table 3 until a quotient T1 and a remainder R1 are formed. The remainder is attached to the number in the circulating store and the quotient T1 divided again to form in this case a remainder R2 and a quotient T2 less than ten. The quotient T2(7), R2(4) and R1(2) thus form the b.c.d. In many cases numbers to be converted or the converted b.c.d'.s appear in the wrong order, i.e. with the least significant bit of the least significant digit appearing first instead of the most significant bit of the most significant digit. To correct this the least significant b.c.d. digit is fed to the stores Sp where it is reversed in order. The remainder of the digits are circulated via switches W2, W3 and the least significant digit is attached on the end adjacent the most significant digit. This is repeated for the next least significant digit which is also re-attached after the m.s.d. and before the l.s.d. The process is repeated for the remainder of the digits.

Abstract: 1454809 Production of reducing gas TEXACO DEVELOPMENT CORP 23 Oct 1974 45944/74 Heading C5E In a process for the production of a reducing gas (comprising principally H 2  and CO) by the partial oxidation of a hydrocarbonaceous fuel with a free oxygen containing gas in the reaction zone of a free flow gas generator, NH 3  is added to the reaction zone as a temperature moderator in an amount 0À01-1À5 lbs. NH 3  per lb. of hydrocarbonaceous fuel, and no H 2 O is introduced into the reaction zone other than that produced therein. The ammonia is introduced in liquid or vaporized anhydrous state, either separate from or admixture with the fuel. The reaction is carried out at an autogeneous temperature of 1500-3500 ‹F. and a pressure of 1-350 atm. A variety of hydrocarbon fuels may be employed, including solid, liquid and gaseous hydrocarbons, oxygenated organic material, slurries of carbonaceous fuels in liquid hydrocarbons, gas-solid suspensions and gasliquid-solid suspensions. Many examples of suitable compounds are given. Various treatments may be applied to the effluent gas, e.g. cooling, by passage through a waste heat boiler, to temperatures of 400-2300‹ F., and cleaning and purification operations such as scrubbing to remove suspended solids and removal of gaseous impurities by physical or chemical absorption or refrigeration. In particular, the effluent gas may be scrubbed, with a liquid hydrocarbon to produce a slurry of particulate carbon which may be suitably concentrated and recycled to the gas generator.

To determine whether a character font is suitable for use in an automatic character reader characters are compared in pairs by preparing transparency masks of the characters measuring " A", the transmission of light through the first mask, " B", the transmission of light through the second mask, " C", which is the maximum transmission of light through both masks superimposed, the masks being relatively shifted to produce the maximum, and " D", which is the transmission of light through the area of a mask without a character, and forming the quantity A + B +2C/D. This is a measure of the difference between the two characters. The quantities A-D are obtained in the apparatus shown, light from lamp 1, Fig. 1 (not shown), being passed through the various slides 4, 5 to fall on a photo-multiplier 8. The outputs A-D are indicated on meter 9 and the above quantity is calculated. The process is repeated for all pairs of characters in a font and the difference between each pair must be greater than a certain value for the font to be suitable for an automatic reader.
