Title: Process of diffusion chromium treatment of steels
IPC: C23C10/40
Filed: 1953-11-30
Abstract: Chromium is introduced by diffusion into the surface of steel containing one or more of Ti, Ta and Nb in quantity more than sufficient to bind the carbon content, the chromium-rich surface so produced being resistant to inter-crystalline corrosion.  The contents of Ti, Ta and Nb present should be respectively at least 5, 10 and 18 times the C content, with corresponding reduction when two or all are present together.  Steels containing 0,02-0,15 per cent C with 0,10-0,8 Ti, or 0,20-1,8 Nb, or 0,36-2,0 Ta and a steel containing 0,05 per cent C with 0,15 per cent Ti, 0,15 per cent Nb and 0,10 per cent Ta are referred to.  The steels may also contain Mn, Si, Mo. Applications 5814/39 and 13929/40, both as open to inspection under Sect. 91 of the Patents and Designs Act 1907-46, are referred to.

Title: Improvements relating to gramophones
IPC: G11B17/00
Filed: 1923-02-20
Abstract: 211,702. Croockewit, J. H. Feb. 20, 1923. Multiple machines.-An automatic gramophone is adapted to play both sides of a number of records. The records are carried' by a platform which is rotated step-by-step to bring each record in turn over the turntable which ascends, through a hole in the platform, to play the record. After the playing the turntable descends and the platform rotates another step. During this rotation, the played record is turned over by suitable gearing so that during the second rotation of the platform the other sides of the records are played. As shown, six records 31, Fig. 3, are held by gripping devices 69 above holes in a rotatable platform 57. Assuming that one record is in position over the turntable, the following sequence of operations takes place. (a) The turntable, which is continuously rotated by suitable mechanism, is raised by means of a lever 23, Figs. 1 and 2, engaging the bottom of the turntable spindle 25. The lever is raised by a cam 21 on a shaft 22 rotated by gearing including bevel gearing_11, 18 which is put into gear by sliding the shaft 17 by means of a link 15, lever 13 and starting handle 12. The turntable is held raised bv a sliding bar 26 engaging a groove 28 in the spindle, (b) The record is played, the tone arm 33 travelling inwards and taking a lever 36 with it. A cam groove at the end of the lever operates link mechanism which moves a bell-crank lever 42, 43 into the path of a stud on a rotating wheel 9. The cranked lever 42, 43 when operated by the stud moves the bar 26 and releases the turntable spindle. (c) The turntable descends, whereupon a projection 46 on the underside of the turntable engages a stud on a pulley wheel 6 which by its rotation operates a train of wheels 50 whereby (d) the platform is rotated another step and (e) the tone arm is returned to the starting position. The platform is rotated by the wheel 54 and the tone arm is returned by the disc 56 which has a pawl 58 engaging a notch in the hub of the lever 36. The records are held by gripping devices 69 carried by spindles 70 mounted to slide and rotate in bearings 71. One of the spindles has a pinion 76 which during the part rotation of the platform runs over a fixed rack 77 thereby (f) turning the played record over to bring the other side uppermost.

Abstract: 1,179,941. Valves. AMERICAN RADIATOR & STANDARD SANITARY CORP. 2 Feb., 1967, No. 5025/67. Heading F2V. A valve, for mixing hot and cold water, comprises a brass valve body 40 and, removably secured to it, a plastics valve cartridge 50 housing all the moving valve components and consisting of a body 55 and a cap 60 welded to it. Fluid inlet and outlet passages (43a, Fig. 26, not shown), 43b and 45, respectively, are formed within the valve body 40, the inlet passages being circumferentially spaced from each other and also spaced from the outlet passage which extends substantially axially through the body before joining an outlet nozzle tube 37. Control of fluid is by way of two ceramic discs 70 and 80, the former being fixed against rotational movement within the cartridge and having shaped apertures aligned with the inlet and outlet passages and the latter being rotatably and slidably movable with respect to the former and having formed in its flat underface an elongated and generally oval recess 81. A handle 34 is pivotally mounted, by means of a stainless steel pin 95, within a plastic pivot race 85 which itself is rotatable within the cartridge body but fixed against axial movement in one direction by integral flanges which engage the underside of cartridge cap 60, and inhibited from axial movement in the other direction by tubular rubber inserts 65a, 65t bearing on the valve body 40 and engaging the fixed disc 70. Pivotal movement of the handle brings the inlets, via recess 81, into the desired degree of communication with the outlet whilst rotational movement of the same, which may be effected before the pivoted movement, serves to vary the ratios of hot and cold water flowing to the outlet. A cup-shaped casing 100 surrounds the valve and is finished off by a cap 110 secured to, and movable with, the handle.
