A quantity, such as speed, temperature, pressure or horsepower is maintained at a fixed value by a system having an oil pump K, a reset sleeve 16 provided with a piston 15, a selector spool 36 and a metering spool 24 operable within the sleeve and interposed between a diaphragm 37 and a compression spring 35 provided with adjusting means 27, a variable metering notch 25 in the metering spool 24 providing communication between a bore 14 and the bore 20 of the sleeve 16, first and second lands 41, 42 on the selector spool 36, a pressure cavity 52 connected to a fluid supply means and provided with a fixed orifice 52a in communication with an annular cavity 23, a bore 54 in communication with the cavity 23 and connected to the discharge side of the fluid supply means, a port 21 in the sleeve 16 to provide communication between the cavity 23 and the bore 14, a relief valve 58 between the cavity 52 and the bore 14, a drain conduit 50 between the bore 14 and a sump I, a fluid passage 55 inter-connecting the pressure cavity 52 and a pressure annulus 36a between the first and second lands 41, 42, afluid passage 48 connectable between the pressure annulus 36a and the chamber at one side of the piston 15, and a fluid passage 47 connectable between the pressure annulus 36a and the chamber at the other side of the piston, a drain passage 49 connecting the drain conduit 50 and the left end area of a bore 17 and a signal transmitting means B inter-connected with respect to the selector spool 36 and a controlled quantity in the system. In the preferred embodiment, a centrifugal pump K is driven through a slipping clutch F controlled by a piston H subjected to the pressure in conduit 54, the pressure cavity 52 being supplied by an oil pump D. When the pressure in the pump delivery line A varies from the fixed value, the diaphragm 37 displaces the metering spool 24 to vary the bypass flow into the conduit 50 and thus adjust the slip in the clutch F. The selector spool is also displaced by the diaphragm to cause the piston 15 and sleeve 16 to increase the rate of opening or closing of the metering notches 25. Adjustable needle valves may be provided in the passages 47 and 48 to enable the response time to be regulated.

Abstract: 188,346. Signal Ges. May 5, 1921. Addition to 157,755. Testing physical qualities of materials.-Comprises a method of performing 'torsion tests by including the specimen in an oscillating structure which is excited to oscillations in the frequency of its natural frequency. In the form shown in Fig. 1 the test piece 1 is fixed at one end to the hood 8 and carries a mass 2 at the other end. This mass is subjected to the influence of a compound alternating magnetic field in which the poles 3, 4, 3<1>, 4' are at 90‹ to one another. This field is excited by coils supplied from an alternating current generator 7, a condenser 10, Fig. 3, being placed in circuit with two opposite coils and a choke coil 9 in circuit with the other two coils so that there is a phase displacement of 90‹ between the currents in two adjacent coils. To test a shaft, it is suspended in the middle and furnished with masses at the ends upon which exciting forces are exerted in opposite directions. When the shaft is long the test is carried out in sections, one part being fixed while a mass applied at another part is excited. In the modification shown in Fig. 6 a large mass M is formed with a tubular extension R along the axis of which lies a rod S fixed to the tube at the lower end. The rod carries a mass m fitted with parts forming the armatures of electromagnets the fields of which are carried by the part M. The specimen P is fixed at one end to the yoke of the mass M and is acted upon by the oscillations of the mass m through the medium of an arm.

Title: Improved process for the manufacture of steel
IPC: C21C5/28
Filed: 1957-04-23
Abstract: Basic Bessemer steel is carburized so that the carbon content is at least equal to the oxygen content and is then degassed under reduced pressure by periodically increasing and decreasing the depth to which a tube connected to a vacuum degassifying vessel dips into the molten metal in a ladle whereby part of the contents of the ladle enter the degassifying vessel and, after degassifying and heating are returned to the ladle, theh operations being repeated until the steel is degassified.  The carbon may be added before or during the vacuum treatment e.g. in the apparatus described and claimed in Specification 801,518, with or without the addition of oxygen.  The degassed metal may be cast in the atmosphere or in the presence of a non-oxidizing gas.  A deoxidizing substance and/or alloying elements may also be added to the metal while in the vacuum chamber.

Title: Improvements in or relating to the manufacture of permanent magnets

Abstract: 577,135. Heat treating permanent magnet alloys. NEILL & CO. (SHEFFIELD) Ltd., J., and EDWARDS, A. Aug. 21, 1940, No. 13259. [Classes 72 and 82(i)] - In the manufacture of an isotropic permanent magnet, an iron base alloy containing 5-10 per cent of aluminium, more than 7 and less that 12 of nickel, and 16-30 of cobalt is subjected to the action of a magnetic field while cooling from 1200-1280‹ C. down to from 700 C. to 600‹ C. The alloy may also contain up to 10 per cent of copper or up to 5 of titanium but if both elements are present their total must not exceed 10 per cent. The ratio of the aluminium content to that of the nickel is 7 to 11. The cooling is effected at an average rate of ¢‹ C.-5‹ C. per second, preferably 1.5‹ C.- 3.0‹ C. The rate of cooling is selected according to the nickel and aluminium contents, being slower for the lower proportions of nickel and faster for the lower porportions of aluminium. An ageing treatment may be applied to the alloy after its subjection to the magnetic field, e.g., by heating it to a temperature exceeding 450‹ C. but not 750‹ C. for 1-24 hours and the alloy may then be subjected to a second magnetic field of the same direction as the first. The alloy may be prepared as described in Specification 450,431 and in the cast condition may be subjected to the process described in Specification 478,127 to improve its machining qualities and machined before subjecting it to the action of the magnetic field. In an example, an alloy containing 52 per cent of iron, 7 of aluminium, 11 of nickel, 25 of cobalt and 3 of copper is cooled from 1200‹ C. to 600‹ C. at an average rate of 2‹ C. per second in a magnetic field of 2000 gauss or more. After further cooling at any desired rate the alloy is aged for 24 hours at 550‹ C. cooled in still air to room temperature and finally magnetised in a field of 750 gauss or more. Specification 522,731 also is referred to.

Abstract: 265,440. Renault, L. May 26, 1926. Dynamometers; systems for testing motor vehicles.-Relates to apparatus of the type comprising belt tracks, brake apparatus, and dynamometers in the anchoring chains for the vehicle, and comprises two moving tracks constituted by endless belts a, b running over pulleys c, d, the pulleys c corresponding to the rear axle of the vehicle being fixed on the same shaft f on which is fixed another pulley g driving a brake apparatus r, while the pulleys d corresponding to the front axle are fixed on independent shafts supported in pedestals n which can be adjusted by screws o to permit of tensioning the belts a, b. Jockey pulleys h are provided and the whole apparatus is located in a pit p so that the tracks are at the ground level. In use, the motor car is brought on to the tracks and is anchored in front and at the rear by cords or chains fitted with tightening screws. The engine is started and the power test made at different speeds by operating on the brake apparatus. An acceleration test may be made by observing the time taken to work from a low speed to a high speed by operating the acceleration pedal. For testing the brakes, the vehicle is run at a certain speed and the brakes applied, the time taken for the wheels to come to rest being noted. Moreover, the way the vehicle keeps on the tracks during braking gives an idea as to whether the brakes on either side need adjustment. Dynamometers may be attached to the cords k, l to indicate the force of traction.
