Title: Improvements in and relating to cap mounting devices for carbon electrodes
IPC: H01M50/564
Filed: 1929-10-04
Abstract: 337,550. Blache, H. March 28, 1929, [Convention date]. Connections to carbons.-A device for supplying metal caps to a machine for assembling them on the ends of carbon electrodes comprises a selecting device which separates the caps into two groups the members of which face in opposite directions and are passed to two shoots one of which is twisted through 180. The shoots lead into a common passage from which the caps, now all facing in the same direction are fed singly to the assembling machine. In the construction of apparatus described, the caps 16, Figs. 4 and 5, are placed in a hopper 1, Fig. 1, and agitated by a rotary brush 4 or other form of agitator so as to pass into a passage 2. The selecting device is contained in the casing 3 and comprises two spaced discs 11, 12 mounted on an intermittently rotated shaft 9 driven by a pawl-and-ratchet mechanism 10, 7, 8. The disc 11 has peripheral recesses each accommodating one cap from the passage 2, and the disc 12 carries opposite each recess a spring-pressed plunger 14 biassed away from the disc 11. In the rotation of the selecting device a cam 17 actuates the plunger against its spring and discharges those caps with the closed end towards the plunger into a straight shoot 18, Fig. 4. Those caps oppositely directed are not discharged and pass to another shoot 20 twisted through 180 into which they are discharged by a fixed guide 19, Fig. 5. The two sheets merge into a common channel 21, provided with an agitator in the form of a hexagonal disc; from which they are fed by a reciprocating slide 26 to the assembling device 27.

Title: Improvements in or relating to explosives
IPC: C06B21/00
Filed: 1927-11-11
Abstract: 305,722. Scott, A. C. Nov. 11, 1927. Explosives.-Relates to explosives of the kind comprising a charge of oxygen-carrying salts such as potassium chlorate, ammonium nitrate or the like, adapted to be impregnated with a fuel, and consists in incorporating with the oxygen-carrying salts a small proportion of an inert silicate having a readily subdivisible laminated or fibrous texture, such as asbestos fibre, to which may be added another similar silicate, such as mica. These silicates prevent the subsequent exudation of the fuel. In one example, 65.5 parts by weight of potassium chlorate are mixed with 30 parts of sodium nitrate, and 3 parts of asbestos; and the fuel for absorption by this mixture comprises 10 parts of orthonitrotoluene, 1 part of kerosene, and 0,5 part of castor oil. If a granular explosive is to be produced, the salt mixture is moistened, pressed, and granulated before impregnation with the fuel. Instead of sodium nitrate, other salts such as potassium nitrate, sodium chloride, and potassium chloride may be used with potassium chlorate; and with potassium perchlorate, ammonium nitrate may be used. Specifications 2139/83 and 30442/97, [both in Class 9 (i), Ammunition &c.], and 187,012, are referred to.

Title: Improvements in or relating to pendulum controlled mechanisms
IPC: G04C3/02
Filed: 1924-12-18
Abstract: 242,472. Craig, E. E. Dec. 18, 1924. Escapements; electric clocks; driving-mechanism, weight.-In a pendulum-controlled escapement the pendulum periodically releases a ball which frees an escape wheel and causes an impulse to be imparted to the pendulum A. The latter is suspended at A<1> and has a cross-head B carrying pins B<1>, B<2> of which B<1> coacts with a three-armed member E, E<2>, E<3> pivoted at E<1>, the arm E<3> normally bearing lightly to the right against the pin B<1>. Co-operating with the pin B so as to press lightly to the left against it is an arm C<3> rigid with a shaft C' and with a platform C for the ball D. The scape wheel G is held by a detent H rigid with a counterweighted lever F, F<2> which is forked at F to embrace the scape wheel; the movement of this lever is limited by stops F<3>. With the pendulum at rest in vertical position the platform C is adjusted so that the ball D will just not remain on it. In normal operation, as the pendulum swings to the right, the pin B<2> swings the arm C<3> and platform C clockwise and the ball passes off the platform on to a runway E<4> on the arm E, causing the arm E<3> to give an impulse to the pendulum. The ball then passes on to the forked lever F, lowering the detent H and releasing the scape wheel. The ball being now between the teeth of the scape wheel is raised thereby, and as it travels to the right a fixed guide J slides it on to a runway I, by which it is returned to platform C, ready for the next beat of the pendulum. In a modification, the ball is carried on a platform rigid with the pendulum and operates the scape wheel every two seconds as above. The scape wheel has fifteen teeth, and once per revolution, i.e. each half-minute, a cam rigid therewith releases mechanism to impart an impulse to the pendulum and to close contacts which energize a magnet, thereby raising a weighted pawl one pin on a wheel driving the scape wheel. These contacts may also be used to send impulses to secondary clocks.

Filed: 1936-11-09
Abstract: Cellulosic material is reacted in the presence of a base with an alkoxyalkylating agent in an amount corresponding to at least two molecular proportions for each unit of cellulose, and the reaction is stopped when the product becomes soluble in water.  In a modification, the molecular proportion of alkoxyalkylating agent is not more than two for each unit of cellulose, and the reaction is stopped when the product reaches the desired solubility in alkali. In the group RO which substitutes the hydroxyl groups of cellulose, R contains ether oxygen atoms, and the ratio of these oxygen atoms to carbon atoms is at least one to two.  In a further modification, the alkoxyalkylating agent has an alkoxyether group RO having at least two ether linkages and a ratio of ether oxygen to carbon of less than one to two, the product being insoluble in water or in cold alkali. The highly substituted alkoxyalkyl ethers of cellulose are soluble in organic solvents, e.g. aromatic hydrocarbons, chloroform, dioxane, ethyl acetate, and pyridine. As suitable alkoxyalkylating agents, there may be used the halides, sulphates and the arylsulphonates, particularly the p-toluenesulphonates of methoxyethanol, ethoxyethanol, ethoxyethoxyethanol, or methoxypropanol.  A number of examples are given.  Specification 327,157, [Class 2 (ii)], is referred to.

Abstract: 1398779 Rotary positive-displacement machines DANFOSS AS 3 July 1972 [13 Aug 1971] 30983/72 Heading F1F In a gerotor-type motor, or pump, with two torque/speed (or delivery/speed) ranges the flow of fluid to and from the working chambers 5 between a ring 3 and planetary wheel 4 is controlled by three groups a, b, c of axially-orientated grooves 11 in a rotary valve-member 23 coupled to the wheel by a shaft 24, the grooves co-operating with openings 9 in a housing 17. In Fig. 1 the housing and valve member are indicated diagrammatically at 7 and 8. The grooves 1 1a, 11b, 11c communicate continuously with pipes 12, 13, 14, respectively, which in turn are connected as shown in Fig. 1 through unions 1, 2 to working- fluid supply and discharge pipes (not shown). A changeover valve 15 actuated by the pressure differential between the unions 1, 2 connects the pipe 14 to one union or the other. At low pressure differentials the pipe 14 is connected to the union 1; and thus the supply pipe communicates with one half of the grooves and the discharge pipe with the other half, as usual. At higher pressure differentials the pipe 14 is connected to the union 2 so that the supply pipe then communicates with only one quarter of the grooves, the remainder of the grooves being in communication with the discharge pipe. As a consequence the torque is halved and the speed doubled, approximately. Reversal of the supply and discharge pipe connections is facilitated by non- return valves, Fig. 4 (not shown).
