Title: Method of producing a cube-on-face texture in silicon and/or aluminium-containing iron alloy sheet or strip
IPC: C22C38/06
Filed: 1961-02-03
Abstract: A cube-on-face texture (100) [001] is produced in iron alloy sheet or strip material, containing 0.5 - 3.5% Si or 0.5 - 2.5% Al or both together in total amount from 0.5 to 3.5%, the remainder being iron with or without impurities, such as S, P, Mn, C, which material has been hot and cold rolled with intermediate heat treatments and possibly allowed to age after the final cold roll, by final annealing at between 1000 and 1400  DEG C. in a gas atmosphere or a vacuum, effected either by slowly heating (about 0.5  DEG C./min.) with a change of atmosphere or vacuum before reaching the ultimate temperature, or abrupt heating (e.g. to 1250  DEG C. in 25 minutes at about 50  DEG C./min.) preferably in coil form, with a change of atmosphere or vacuum due to the release of gases from the material, then subjecting the material to a silicon and/or aluminium vapour, e.g. by placing FeSi2 or an iron alloy containing silicon near the material or introducing into the annealing furnace a compound decomposing to form Si, such as SiH4 or Si3H8, after the ultimate annealing temperature is reached, so as to suppress furrow formation along the grain boundaries.  The first atmosphere or vacuum may be either inert or have a carburizing, nitriding or oxidizing effect, e.g. argon, a vacuum of 0.1-0.005 mm. Hg., a hydrogen-methane atmosphere, or nitrogen; the second may be a high vacuum, hydrogen or helium. U.S.A. Specification 1,965,559 is referred to.

Patent GB-567882-A (GB)
Title: Improvements in salt-bridge tubes
IPC: G01N27/30
Filed: 1943-03-17
Abstract: 567,882. Glass manufacture. KENT, Ltd., G. March 17, 1943, No. 4334. Convention date, April 1, 1942. [Class 56] [Also in Group XXXVI] A salt-bridge tube for the reference electrode of an ion-concentration cell is formed with a minute crack to provide for diffusion of the salt-bridge solution into the solution surrounding the salt-bridge tube. This is effected by making a small hole in the salt-bridge tube while it is at a temperature sufficiently high to render it tacky and sealing this hole with a plug of material, such as another glass, having a different coefficient of expansion so that a crack is formed on cooling. Apparatus for determining pH values in which such a saltbridge tube is employed, is shown in Fig. 1. The solution under test is passed through a chamber 2, containing a glass electrode 3, and a chamber 4 in which is disposed a reference electrode 5. Between the reference electrode 5 and the solution S is a salt-bridge solution 6, such as potassium chloride, contained in a tube 7 which has a diffusion opening 8 affording a conducting path between the reference electrode 5 and the solution S. A movable contact 9 alternately engages contacts 10, 11 and thereby subjects a condenser 12 alternately to the voltage developed by the ion-concentration cell and to the voltage tapped off by a slider 13 on a potentiometer 15. If these voltages are equal, the charge on the condenser is unchanged and the potential of the grid 16 of a valve V remains constant so that there is no change in the current traversing a resistance 17 in the anode circuit. If the fixed contacts 10, 11 are not at the same potential, the voltage drop across the resistance 17 is changed and is recorded by a recording galvanometer 21, the deflection of which also effects a balancing adjustment of the potentiometer 15. The oscillation of the contact 9 between the contacts 10, 11 is effected by a cam 23 driven at constant speed by mechanism 24. The aperture 8 is formed by heating the 'tube 7 until it is soft, inserting a pointed hook and forcing it against the side to make a small opening 25, Fig. 2, and filling this with a molten or tacky globule of another glass having a different coefficient of expansion. If this coefficient is higher than that of the tube, a crack is formed partly surrounding the plug. If the coefficient of expansion of the plug is lower than that of the tube, radiating cracks form in the tube. For a tube of small diameter, the end of the tube is sealed with a globule of glass of a different coefficient of expansion and the end blown into shape. Specifications 483,072, [Group XXXVI], and 560,212 and U.S.A. Specifications 1,935,732 and 2,108,294 are referred to.

Title: Process for the preparation of 4-hydroxy-3-keto-í¸-steroids
IPC: C07J1/00
Filed: 1962-02-05
Abstract: 4-Hydroxy-3-keto-D 4-steroid is prepared by treating a 19-nor- or a 10b -methyl-4-halo-3-keto-D 4-steroi dissolved in a t-aliphatic alcohol with oxygen in the presence of an alkali metal salt of a t-aliphatic alcohol at from 10 DEG  to 50 DEG C. and, in the case of 10b -methyl reactant, catalytically hydrogenating the resulting 4-hydroxy-3-keto-D 4,6-steroid produced until one mol of hydrogen is absorbed.  The above process may be modified in that the resulting 4-hydroxy-3-keto-D 4-steroid is acylated to form the corresponding 4-acyloxy compound.  The initial reactants used in the above process may be a 4-chloro-D 4-steroid of the androstane, 19-nor-androstane and 17a -hydroxy-pregnane series such as 4-chlorotestosterone acetate, 4-chloro-17a -methyl-testosterone and 19-nor-testosterone, 4-chloro-19-nor-testosterone and 4-chloro-4-pregnen-17a -ol-3,20-dione.  Therapeutic compositions having anabolic, androgenic and progestative activity contain as the active ingredient a 4-hydroxy (or acyloxy)-3-keto-D 4-steroid and a pharmacologically acceptable carrier.

Title: Improvements in or relating to railway carriages and wagons and the like
IPC: B61G11/12
Filed: 1920-02-13
Abstract: 161,774. Hirst, T. E. C. Feb. 13, 1920. Buffers.-A buffer which can also be applied beween the axle box and underframing of a vehicle, of the type described in Specification 159,349, [Class 108 (iii), Springs &c.], consists of a cylindrical outer casing a<x> in which works a main piston e, attached to the hollow buffer spindle b contains a spring b<1> which keeps a piston valve d, the stem of which passes through the main piston e, on to a seating e' formed on a shoulder in the main piston. Both pistons are fitted with hydraulic packings. The interior of the buffer casing a<x> is partly filled with oil through a hole x in the side. When the buffer plunger is compressed the force is taken up the main-spring a until the piston valve stem d<2> reaches the surface of the oil; on further compression the piston valve is forced in and compresses the spring b<1> above it. A hole is made in the side of the extension e<2> of the main piston which communicates with a groove d<3> of variable depth cut in the piston valve extension d<2> to enable oil to pass above the seating e'. In a modification, the hydraulic packing d<1> and the groove d<3> in the piston valve are dispensed with and an annular groove containing hydraulic packing is made near the end of the extension e<2> of the main piston.

Title: Pipe couplings
Inventor: STEPNICA VLADIMIR
IPC: F16L37/54
Filed: 1957-02-08
Abstract: 830,474. Pipe couplings. SIGMUND PUMPS Ltd. March 17, 1958 [Feb. 8, 1957 ; July 25, 1957], Nos. 4468/57 and 23824/57. Class 99(1). In a coupling particularly for irrigation pipes and of the kind comprising a socket 1 to which a pipe 3 is joined through a flexible sealing gasket 6, and latching means on the socket and the pipe whereby the latter are maintained coupled and capable of being automatically latched and unlatched by imparting relative movement between the socket and the pipe, the latching means consist of a hook bar 10 pivoted on the exterior of the socket and having at least two cam elements 12, 13 of elliptical form in section and spaced apart lugs 15 on the pipe to permit engagement of the hook bar therebetween. At least one of the lugs is shaped as at 16 for engagement with the cam elements upon axial movement of the pipe towards and into the socket so as to rock the hook bar away from the axis of the socket and from between the lugs, and at least one of the lugs is shaped as at 17 for hooking cooperation with one of the cam elements nearest the free end of the hook bar when the latter is located between the lugs. As shown, the gaskets 6 of rubber or similar elastic water impervious material are housed in annular grooves 5 in the socket, the gaskets being of channel, or H-section, or of O-ring form. The undersides of the cam elements 12, 13 and of the bar 10 lie substantially in a common plane. The socket 1 is provided with a flat-ended base 7 and a screw threaded boss 25 for connection of a stand pipe. Uncoupling of the pipe 3 is effected by urging the pipe into the socket until the cam side 16 of the lug 15 engages the cam element 13 thereby disengaging the hook bar 10 from between the lugs whereupon the pipe can be rotated through a small angle and withdrawn from the socket. Pipes may be secured to both ends of the socket by such latching means. Alternatively, one end of the socket is formed with a semi-cylindrical extension 18 having arcuate arms 19 contractible by a bolt 20 about a pipe 2, stops 21 being provided within the socket to limit the extent of entry of the pipe into the socket. Specification 830,475 is referred to.

Title: Improved machine for splitting fish
IPC: A22C25/16
Filed: 1921-02-08
Abstract: 178,613. Webb, A., Belton, W. A., and Reingpach, C. P. B. Feb. 8, 1921. Fish, dressing. - The fish are carried, bellies downward, in carriers E, mounted on an endless conveyer, and are split through the backs by an oscillating knife S, which does not, however, cut through the bellies. Each carrier E comprises a fixed portion a<2> and movable side and bottom portions a, b, which are normally opened by springs e. The portions a<2>, a, b are shaped to receive a fish, which is gripped, when the carrier is beneath the knife, by the pressure of spring- pressed rollers W on the portion a. In consequence of the one-sided adjustment of the carriers, the fish are split alongside the backbones, the cutting of which is thus avoided. The carriers are spaced, and the conveyer speed is adjusted, so that a complete cutting-stroke occurs whilst the carrier is below the knife and the return stroke is completed whilst the next carrier is being positioned. The arm T carrying the rotary knife S is pivoted to a bracket J, which carries the crank-operated rod U which oscillates the arm T. The knife mechanism is operated by sprocket-wheels and chains. A non-rotary knife may be used.

Title: Improvements in tachymetric correcting devices, more particularly for use in connection with sighting apparatus for artillery
IPC: F41G5/00
Filed: 1936-02-14
Abstract: 453,744. Fluid-pressure servomotorcontrol systems. SCHNEIDER & CIE, and FIEUX, J., 42, Rue d'Anjou, Paris. Feb. 14, 1936, No. 4549. Convention date, April 4, 1935. [Class 135] [See also Group XX] A tachymetric correcting device for artillery firing and like applications, for applying a correction in respect of the angular velocity of the sighting device when following a moving target, comprises a servomotor 25 for moving the member to be corrected which is controlled by a gyroscope 1. The gyroscope casing 2 is pivoted on trunnions 4 in a frame 3 which frame is connected to the telescope or sighting device so that it moves about a vertical axis in accordance with the angular movement impressed upon the telescope by the observer. The angular velocity of this movement produces a precessional thrust by the gyroscope casing 2 which moves a piston member 9 of a pressure-reducing device 10 which controls the pressure from a pump 50 to a spring loaded pilot piston 22. This pilot piston regulates pressure fluid from the pump 50 to either side of the servomotor piston 25, a follow-up sleeve 23 being connected to the piston 25 so that the piston 25 assumes definite positions for definite pressures of the fluid acting on the pilot piston 22, which pressures are proportional to the angular velocity of the sighting telescope. In Figs. 8 and 9, a gyroscope is shown mounted for precession about two perpendicular axes, the outer casing 56 being mounted for rotation in a vertical plane on the frame 57 which is itself rotatable in the horizontal plane. The angular velocity of the sighting device in both a horizontal and a vertical plane can thus be impressed upon the gyroscope and the precessional thrusts arising are transmitted to pressure-reducing valves 9, 9<1> each of which controls a correcting servomotor as in Fig. 1. The rotor of the gyroscope may be driven by an electric motor through a coupling which allows for the precessional movement of the gyroscope, and the speed of this motor may be controlled by a governor device and further by a fluid-pressure device according to the distance of the objective, which will enable a further correction to be obtained.
