Title: Age-hardenable alloys
IPC: C22C38/10
Filed: 1963-10-11
Abstract: An alloy contains at least 16% Ni, at least 12.5% Co, 0-6% Nb, 0-12% Ta, 0.5-1.5% Ti, 0-1% of each of Si, Mn and Al, 0-0.2% C, 0-0.1% Ca, the balance being at least 31% Fe and impurities. The percentages of Ni and Co are governed by the relationship 1.235 Ni+Co=55.8 to 66.8, and the percentages of Nb and Ta by the relationship Nb+0.5 Ta= 2.4 to 6. Cu up to 1%, S and P each up to 0.05% and Cr, Mo and W each up to 1% may also be present.  The alloy may be hot worked, annealed at a temperature in the range 1400-2100  DEG F., rapidly cooled, cold worked to an extent not greater than that equivalent to a reduction in area of 45% on cold rolling and then age hardened in the range 1100-1300  DEG F. The cold working may be omitted. In examples, the use of a heat treatment at 1500  DEG F. or 1600  DEG F. for 1 hour followed by water quenching follows the cold working and precedes hardening for 5 hours at 1200  DEG F.  The alloys may be used for making resilient articles such as springs, pressure sensitive elements or vibratory reeds, electro-mechanical filters, magnetically responsive elements, diaphragms and bellows.

Abstract: 1,271,365. Treating waste water. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 22 Aug., 1969 [27 Aug., 1968], No. 40870/68. Heading F4B. Apparatus for treating dilute waste water containing toxic organic and inorganic substances comprises in combination a wet scrubber 1 and a fluidized bed incinerator 2. In operation, effluent gases from the incinerator pass into the wet scrubber 1 through conduit 11 countercurrent to the dilute waste water, thus removing the solid particles from the effluent gases and evaporating the water to concentrate the waste solution; the solution passing into the incinerator through conduit 12. Hot gases from a combustion chamber 3 flow through a conduit 17 into the incinerator to vaporize remaining water and form a bed of inorganic solid particles, the organic compounds being driven into the gaseous phase. The inorganic solids are continually discharged from the incinerator through a pipe 18. Hot combustion gases from a chamber 4 pass through a conduit 25 into a secondary firing chamber 5 to mix with the effluent gases emanating from the wet scrubber 1 through conduit 13. In chamber 5, the organic compounds in the gases are completely oxidized. The superheated water vapour and gaseous products from chamber 5 pass through conduit 26 to a heat recovery boiler 6 for steam generation.

Title: Mechanism for automatically correcting the position of the tool  cutting edges of numerically controlled lathes
IPC: G05B19/401
Filed: 1971-09-06
Abstract: 1358913 Machine tool control MASCHINENFABRIK HEID AG 6 Sept 1971 [4 Sept 1970] 41525/71 Heading B3B [Also in Division G3] The position of the cutting edge of a tool for a numerically controlled lathe is corrected at the beginning of an operation by the use of a limit-value transducer, having a tool-contacting feeler, in a programmed measuring position to provide an error signal to the numerical control through a drive means, the error correction being removed at the end of the operation. As shown, a cutting tool 2 of a lathe mounted on slides 7, 8 is positioned in co-ordinate directions by servo-motors 3, 4 controlled from a numerical control device 1. The actual position of the slides is determined by resolvers 9, 10 connected to the device 1 through differential resolvers 13, 14. For programmed setting-up the tool 2 is brought into a measuring position 15 and advanced to touch a transducer 16 having an assembly, comprising rollers 17-20 arranged in a square, which is deflected by the tool to move a cardan-jointed rod selectively engaging limit-value receivers 21-24 which, through a logic circuit, not shown, energize servo-motors 25, 26. The servo-motors 25, 26 rotate the differential resolvers 13, 14 so as to nullify the error determined by the transducer 16. The tool is then brought out of the measuring position and the cutting programme commenced. At the end of a machining programme the correction is removed by reversing the servomotors 25, 26 to the limit of their travel set by cams 20, 30 or micro-switches 31, 32.

Title: Battery charging control circuits

Filed: 1975-09-16
Abstract: 1507148 Control circuits for battery chargers WESTINGHOUSE BRAKE & SIGNAL CO Ltd 16 Sept 1975 [26 Sept 1974] 41820/74 Addition to 1438290 Heading H2H A battery charging control circuit similar to that described in Specification 1,438,290 includes a circuit, Fig. 5a, which detects the gassing point during charging of the battery, the detection of this point causing the control circuit to reduce the charging current. A graph of the increase in cell voltage per minute of charging time against the total charging time shows two maxima between which there is a minimum (X), Fig. 8 (not shown), corresponding to the gassing point. The circuit of Fig. 5a detects this minimum rate of voltage increase and includes two voltage signal stores 1, 2 and two comparators A, B. To detect the minimum value it is necessary initially to detect a negative slope in the graph and each measurement of the rate of change of the battery voltage necessitates the measurement and comparison of the volts/cell of the battery in three successive charge current interruptions, the measurements being initiated by sampling command signals. The first measurement VS2 is stored in the store 2, and the second measurement VS1 is stored in the store 1. The comparator A compares the measurement VS2 with VS1 whilst the comparator B compares the third measurement Vc with VS 1 and the outputs of these comparators are fed to a third comparator or slope detector. The slope detector is connected to a negative slope memory which remains in its initial state until a negative slope is detected. Whilst the memory is in its initial state, a charge state detector holds the charging of the battery in the BULK or constant current charge phase. When the negative slope is detected, the charge state detector is able to change state upon the detection of a positive slope, thereby detecting the minimum point of the graph or the gassing point of the battery. At this instant the control circuit reduces the charging current to start the TAPER charge phase.

IPC: B60T8/32
Filed: 1959-12-09
Abstract: 900,732. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Dec. 2, 1960 [Dec. 9, 1959], No. 41851/59. Class 103 (1). The lapping force on a driver's brake valve is varied by the change-over from controlled fluid-pressure to atmospheric pressure on one of a plurality of pressure-sensitive elements connected to the lapping force applying member. In a driver's self-lapping brake valve 11, the lapping force is derived from a differential piston assembly 16 in which the large area piston 18 is connected to the brake cylinder 12 and the small area piston 20 to a magnetic valve 13. A ball 24 in the valve 13 is moved by a speed-responsive switch 14 to connect the piston 20 through pipe 23 to atmosphere at 25 above a predetermined speed, and to connect the piston 20 to brake cylinder pressure through pipe 22 below that speed. When the brakes are applied by the driver's valve 11 at a speed above that at which the switch 14 is closed to connect the piston 20 to atmospheric pressure, the lapping force is determined by the brake cylinder pressure on the area of piston 18, and the pressure in the brake cylinder corresponds to the position of the driver's valve for high-speed braking. If the driver's valve remains in the same position as the vehicle slows to below the predetermined speed, the valve 13 changes to pass brake cylinder pressure to the piston 20 and a lesser magnitude of brake cylinder pressure suffices to balance the combined pressures of pistons 18 and 20, resulting in a lowered brake cylinder pressure corresponding to the same selected position of the brake valve 11 for low-speed braking.
