Title: Improvement in tool supporting turrets
IPC: B23Q16/10
Filed: 1943-12-14
Abstract: 577,579. Turning. PETERSON, C. E., and OLSON, G. L. Dec. 14, 1943, No. 20974. Convention date, March 18. [Class 83 (iii)] Turrets.-A tool support of the kind comprising a turret member rotatably mounted about a central post on a stationary index plate, the plate member and the turret having co-operating parts to position the turret in any one of its different indexed positions and means being provided for locking the turret to the plate and spring means between the members serving to separate them automatically when the locking means is released, is characterised in that the central post has two screwthreaded portions, the lower portion co-operating with a nut to secure the post to the index plate and the upper portion carrying an internally threaded sleeve on which is a fulcrumed lever adapted to operate a cam for depressing the turret against said spring means into locking relationship, in an indexed position, with the index plate. An index plate 2 is mounted on a guide plate 4 by screws 11 and is formed with a series of radial lugs or teeth adapted to co-operate with complementary lugs or teeth formed on the underside of an annular plate 8 secured to the bottom of the turret 5 by a clamping ring 10 which also serves to centre the turret. Spring-pressed balls 15 may project through holes in the plate 8 to co-operate with depressions 30 in the plate 2 in the various indexed positions. A central pivot post 17 extends upwardly through the plates 2 and 4 to which it is clamped by a nut 18 and the body 5 of the turret is rotatable about a sleeve 26 surrounding a sleeve 21 in screw-threaded engagement with the upper part of the pivot post. The sleeve 26 is held against rotation by means of pins a which enter holes in the nut 18. The'cam-shaped end 22 of a lever 23 is mounted on an upper extension of the sleeve 21 by means of a pin 24. With the lever in the horizontal position as shown, the face b of the cam acting through a crossbar 28, collar 27 and sleeve 26 depresses the turret member 5 on to the index plate and prevents rotation of the turret. An eighth of a turn .of the handle 23 and sleeve 21 effects the final locking of the turret. When the lever is moved so that the face c of the cam contacts the bar 28, springs 16 and balls 15 raise the turret so that the teeth of the plates 2 and 8 are out of engagement and the turret may be rotated to another position. The turret has ten indexing positions and is formed with five vertical radial slots 31 each adapted to receive a tool holder 32 in the form of a body with a hole 33 to receive split bushings 35 designed to take the shank of a tool T and with a vertical slot 34 in which is mounted a clamping block 37. Screws 38 mounted in the turret body engage the block 37 which is thus pressed on to the upper bushing 35 to clamp the tool. A horizontal pivot pin 36 extends through the slot 31 and holder 32. A sleeve 40 prevents the entry of foreign matter into the central portion of the turret.

Abstract: 736,393. Super-regenerative receivers; radio transmitting and receiving apparatus. PYE, Ltd. Dec. 5, 1952 [Sept. 6, 1951 ; Sept. 6, 1951 ; Sept. 17, 1951 ; Sept. 17, 1951], Nos. 21077/51, 21081/51, 21790/51 and 21791/51. Class 40 (5). In a self-quenching super-regenerative receiver of the type in which the frequency of the quench oscillator is within the audio frequency range and varies with the strength of the received signal, the variation of quench frequency is used to operate a muting relay in the audio frequency section of the receiver. Fig. 2 shows a superheterodyne receiver with a self-quenching super-regenerative I.F. amplifier and detector. The output is derived through a low-pass filter which removes the audio frequency quench oscillation. In addition the quench frequency is filtered off and applied to a frequency discriminator to produce a voltage for operating the muting relay. The local oscillator is crystal controlled and the receiver is tuned to different frequencies by switching capacitors across the super-regenerative tuned circuit. Corresponding frequencies for use as a transmitter carrier may be produced by rendering the quench circuit ineffective and beating the resulting intermediate frequency oscillations produced by the super-regenerative circuit with the crystal oscillator output.

Title: Improvements in removing impurities from catalysts
IPC: B01J38/00
Filed: 1957-07-10
Abstract: Catalysts used in treating hydrocarbons are freed of metallic impurities such as vanadium, iron, or nickel deposited during the treating by passing an aqueous solution of an ammonium sulphide, having a concentration between 10% by weight and saturated, through the catalyst at an elevated temperature and pressure followed by passing a medium comprising water through the catalyst.  The washing may be performed with aqueous solutions of ammonium sulphide or polysulphides at 250-500 DEG F. and pressures of 200-600 p.s.i.g. to maintain the solution as liquid.  The catalyst is usually washed with a hydrocarbon solvent such as a liquid sulphur dioxide extract of kerosene to remove adhering oil and then treated with steam or a volatile aromatic oil to remove the wash oil.  It may then be washed with ammonium sulphide solution followed by water, subjected to an oxidative treatment to p  remove carbonaceous deposits and then, if desired, washed again with ammonium sulphide solution and/or water. Alternatively the first ammonium sulphide solution wash may be omitted or the catalyst may be hydrogen treated, oil washed and ammonium sulphide solution treated, if desired, followed by oxidative treatment and further washing.  The catalyst may be cobalt molybdate supported on alumina or other hydrogenation, dehydrogenation, reforming or cracking solid catalyst.
