Disk, wheel, and roller apparatus.-Relates to a grinding-machine of the kind having a workcarrying turret adapted to support a number of rotating work-spindles, and one or more tool-carriages adapted to support rotary grinding-wheels, and in which the tool-carriages are adapted to be reciprocated by hand or by power, and comprises the use of a work-turret which is pivotally mounted on the bed of the machine for adjustment about an axis perpendicular to that of the work-spindles. The turret comprises a ring 12 carrying a head 11, rotatable in the ring by hand or power, or both, and carrying the work-spindles 10, which are rotated in unison by belting or other gearing from a countershaft 16; the head is adapted to be located in the correct positions by pins 12<a>. The ring 12 has a pivot boss 13 on its underside seating in the bed of the machine, whereby the turret may be angularly adjusted in an horizontal plane. One or more grinding- wheels are rotatably mounted in supports 19 mounted on carriages 20, transversely adjustable on a slide 21, and the slide is adapted to be reciprocated by means of a rack 22 driven by a pinion 24, which may, by operation of a slidable clutch sleeve 30, be rotated either by the handwheel 34 or by power through a worm-wheel 26 and a worm 27. The worm is adapted to be driven in opposite directions, being reversed at the end of each reciprocation of the slide from a shaft 28, which is continuously driven from the countershaft and has slidably keyed thereon a clutch sleeve 45 with teeth 46, 46a at its ends. When the sleeve is moved to the left, Fig. 6, the worm 27 is driven through the bevel-wheels 40, 42, the bevel-wheel 40<a>, and a sleeve 40<b> attached thereto and carrying the worm shaft 28<a>; on movement of the clutch sleeve to the right, the worm shaft is driven direct from the shaft 28 in the opposite direction, the bevel-wheels 40, 42 rotating idly. The clutch sleeve is moved by a finger 51 carried by a shaft 50, which is rocked bv a lever 47 the upper end of which is struck by adjustable stops 54 on the slide; the movements. of the lever are made decisive by the spring 58. The reciprocations of the slide may synchronire with the partial rotations of the turret-head 11. In a modification, the work-spindlea are located one above the other when in the working position, and the grinding-wheels are carried by two superposed transversely-adjustable' carriages mounted on the main slide 21.

Abstract: 544,158. Nitro compounds. KODAK, Ltd. June 21, 1940, No. 10681. Convention date, June 23, 1939. [Class 2 (iii)] Unsaturated nitro compounds are prepared by heating formaldehyde with a nitro compound of the formula R.CH  2 .NO  2 , in which R represents hydrogen, halogen or a substituted or unsubstituted alkyl or aryl group, the re-action being effected in the vapour phase and in the presence of a de-hydration catalyst. In this way, nitromethane is converted into nitroethylene and phenylnitromethane into α-nitrostyrene ; nitroethane, nitropropane, chlornitromethane, #-chlornitroethane and the naphthylnitromethanes can be similarly treated. Temperatures in the range 200‹-500‹ C. are preferably employed, together with space velocities above 600. The de-hydration catalyst may be silica gel, alumina gel, activated alumina, or an hydrated sodium.aluminium silicate, and may be activated by appropriate metal salts and oxides. Thus, silica gel is added to lead acetate solution and the product dried ; the product may be used as such or immersed in a solution of chromium trioxide to give a silica gel-lead chromate catalyst, or in a solution of sulphuric acid to give a silica gel-lead sulphate catalyst ; other acetates such as sodium, magnesium or calcium acetate may be used, with other oxides such as tungsten or molybdenum oxide, and phosphoric acid may be used instead of sulphuric acid. Examples are given. The Specification, as open to inspection under Sect.' 91 also describes the-treatment of furfurylnitromethane and pyridylnitromethane. This subject-matter does not appear in the Specification as accepted.

Patent GB-1501335-A (GB)
Title: Process for slow softening water
IPC: C02F1/52
Filed: 1976-03-17
Abstract: In a slow decarbonation of water, the calcium compounds contained in the water are converted into CaCO3 by addition of an alkaline-reacting precipitant and passing through a reaction section, and CaCO3 is precipitated out after addition of a flocculant. Before passing through the reaction section, a finely divided crystalline material is added at least at times. This is preferably obtained by, even before addition of the flocculant, allowing part of the CaCO3 formed to settle and withdrawing it and adding it to the incoming water in feedback.

Title: Improvements in or relating to the manufacture of nuclear fuel
Inventor: HORSLEY GEOFFREY WINTON
IPC: G21C3/62
Filed: 1966-03-11
Abstract: 1,146,015. Nuclear fuel. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 2 March, 1967 [11 March, 1966], No. 10923/66. Heading G6C. [Also in Division C7] Particles of oxygen-containing nuclear fuel are coated with pyrolytic carbon by treatment with a carbon-containing gas to which carbon monoxide has been added. In an example, rounded particles of a narrow size range were prepared from a mixture of carbon, PuO 2  and furfuryl alcohol. The particles were hardened by the action of HC1 gas or formic acid vapour and then fluidized by means of CO and heated to 1400-1500 C; acetylene was then added to the CO to deposit a layer of pyrolytic carbon. The presence of CO prevents reaction between the carbon deposit and the oxygen in the fuel and also prevents volatilization of Pu as plutonium oxycarbide.

Title: Improvements in or relating to electric couplings
IPC: H01R13/527
Filed: 1928-04-13
Abstract: 315,457. Reyrolle & Co., Ltd., A., and Wilson, G. R. April 13, 1928. Plug couplings.-A plug-and-socket coupling is constructed so that three separate movements are required to separate the two members of the coupling. The first movement separates the pins of the plug from their sockets, thus breaking the electrical connection. A second rotary movement is then required before the plug member can be pulled away from the socket member. As shown in Figs. 1 and 2 the plug member comprises an insulating block A carrying pins A<1> and enclosed in a casing B provided with projections B<2> and a key B<3>. The sockets D<1> are carriedby a block D enclosed in a casing F having a rim F<2> interrupted in two places F<3> and provided with a slot D<3> which may be formed at one of the interruptions F<3>. When the two members of the coupling are in contact, an axial movement separates the pins A' from the sockets D' and the key B<3> from the slot D<3>. The projections B<2> engage however with the rim F<2> and prevent complete separation of the two members of the coupling. To effect complete separation of the two members they are rotated relatively to bring the projections B<2> opposite the spaces F<3>, whereupon the plug can be withdrawn completely from the socket member. As shown in Fig. 1 the block D is secured to a member E which is screwed to a casing G which surrounds the casing B and abuts against a rib B<4> on the latter. The parts are held together by locking rings H, J.

Title: Improvements in or relating to electric switches
IPC: H02J7/00
Filed: 1919-05-03
Abstract: 148,006. Wightwick, G. May 3, 1919. No Patent granted (Sealing fee not paid). Lighting systems; systems of charging galvanic batteries.-An electro-magnetic switch particularly for use in connecting a generator to a battery on a petrol-electric vehicle consists of a pair of movable cores 10, 11 placed opposite to fixed permanent or electro-magnets 25, 26, the cores being magnetized to produce polarities as shown, so that one core will move in one direction and the other in the opposite. The magnetization of the cores depends on the position of the motor field controller 24; when the vehicle is going up hill, no resistances are used with the field 23, but when the vehicle is on a level or going downhill, some of the diverter resistances are placed in shunt to the field. The circuit to the coils 18, 19 for the cores 10, 11 is then completed, and the dynamo connected to the terminals A is connected to the batery. When the magnets 25, 26 have to be energized by coils, a relay switch 28 consisting a movable spring cores 33, 34 closes the circuit through the coils, when the controller 24 includes some of the field resistances. On a reversal of rotation of the generator, the reversed current in the field 23 will cause the cores 10, 11 to be magnetized oppositely to the polarity shown, and the direction of current to the battery from the generator is maintained constant.
