Title: Improvements in submarine mines and sinkers
IPC: F42B22/10
Filed: 1916-09-20
Abstract: 157,997. Skipwith, H. L. d'E., Gwynne, A. L., and Sturgeon, R. A. Sept. 20, 1916. Mines, marine.-Relates to mines provided with a sinker controlled by a plummet for automatically mooring them at a given depth, and consists in the provision of means independent of the mooring rope for securing the mine to the sinker, and in conjunction therewith means for delaying the release of the plummet and the mine until the whole apparatus, after being launched, has returned to the surface under its own buoyancy. As shown in Figs. 1 and 2, the mine 1 is secured to the sinker 2 by links 3, one of which is connected to the toe 4 of a hook 10 held to a fixed stop 12 by a ring 11. This ring is connected by a line 14 to the usual pawl of the drum in the sinker and by a line 13 to the plummet 6 which is held in place by a device 6' connected by a shaft 7 to a dash-pot 8<1> and to a wheel 9<1>. When the mine is launched, the wheel 9<1> leaves the rail 37. After the apparatus has returned to the surface, the dash-pot releases the plummet, and the plummet in falling releases the hook 10 and the usual pawl in the sinker, allowing the usual mooring operation to take place. A tightening-screw 15 is provided in the link 3. A hydrostat or a float in the sinker may be used instead of the dash-pot to release the several devices at the appointed time. In another modification, the dash-pot is controlled by a spring and subjected to the weight of the plummet and the buoyancy of the mine in such a way that the plummet falls off and then the mine disengages itself from the sinker.

Title: Improvements in or relating to grinding mills
IPC: B02C7/14
Filed: 1945-05-29
Abstract: 592,828. Grinding-mills. FUEL RESEARCH OORPORATION. May 29, 1945, No. 13463. Convention date, May 12, 1944. [Class 59] A grinding mill comprises a shell, a rotatable shaft extending through the shell, grinding elements including a stator supported by the shell and a rotor mounted on the shaft, one of these elements being secured to its support and the other movable relative to its support, and adjusting means whereby the adjustment of the distance between the discs causes the shell and shaft to move relatively to one another in the direction of their axis. In a water-cooled casing 5, mounted for longitudinal movement on bearing units on a base 2, extends a shaft 13, with an enlarged central part 14. An inner cylinder 16 secured to the casing 5 has an annular lip 21 upon which rests a worm-wheel 22 internally threaded to engage a member 27 keyed for longitudinal movement to the casing. To a flange 19 on the cylinder 16 and to a flange 28 on the member 27 are bolted stator discs 35, 35<SP>1</SP> respectively. Adjacent and co-operating with the outer faces of these stators, floating rotors 40, 40<SP>1</SP>, respectively, are keyed for longitudinal movement to the shaft 14, their outer faces co-operating with the inner faces of stators 50, 50<SP>1</SP> keyed, at 54, to the casing. The outer faces of stators 50, 50<SP>1</SP> co-operate with positioned rotors 55, 55<SP>1</SP> bolted to flanges 58, 58<SP>1</SP> secured to the shaft. In operation, material, e.g. coal-oil mixture, is fed under high pressure through a port 30 into a chamber 32 from whence it passes to the grinding faces where it is forced through into discharge passages 39, 39<SP>1</SP> and into chambers formed in the heads 11, 11<SP>1</SP>. Here it falls on rapidly rotating deflecting members 65, 65<SP>1</SP> and is flung away from the shaft to pass eventually into exit pipes 66, 66<SP>1</SP>. To adjust the distance between the discs, a hand wheel 26 is turned and moves, through a shaft 25, worm 24 and worm-wheel 22, the sleeve to the right which decreases the space between the stator 35<SP>1</SP> and the rotor 40<SP>1</SP>. The pressure of the oil mix between these grinding elements then increases, thus forcing all the other grinding elements to move, and the shell to move to the left, so as to equalize the pressure, giving the same clearance between all the discs. The grinding rings may be of the type shown in Fig. 4, where flange-like peripheral edge portions of the member are hardened to form a grinding surface 75, the inner part 70 of which has groups of slots 72 separated by radial slots 73 as shown ; or in Fig. 11 where the grinding ring is welded to the body and slots 72<SP>1</SP> are all at the same angle to each radius. The rotation of the flanges 65, 65<SP>1</SP> is also used to cool the mill by circulation of air.

Abstract: 566,105. Resistance measurements. RADIO GRAMOPHONE DEVELOPMENT CO., Ltd., MARRIOTT, C. F., and TAYLOR, D. H. J. Aug. 23, 1943, No. 13725. [Class 37] A Wheatstone bridge for determining whether a resistor is within the permitted tolerances above and below its nominal value is so arranged that the galvanometer always moves to one side to indicate that the resistor is within the tolerances and to the other side when the resistor has a value outside either of the tolerances. The standard arm BP contains a resistance Rs which is a close approximation to the nominal value of the resistance Rx to be tested. One comparison arm AP consists of a resistor R100 representing the nominal value. The other comparison arm AQ consists of a resistance r1 in series with either one of two branch parts, of which one contains a fixed resistance r2 and a variable resistance r3 and the other contains a variable resistance r4. The sum of the resistances r1, r2, r3 is equal to the resistance R100 plus the percentage tolerance, and the sum of the resistances r1, r4 is equal to R100 minus the percentage tolerance. A change-over switch CSW permits either of these values to be inserted in the arm AQ and is coupled with a reversing switch RSW through which D.C. is fed across the diagonal AB. With comparison arms of fixed values, a variable voltage supply may be employed so as to permit resistors of a large range of nominal values to be tested with the same sensitivity.-

Abstract: 1,045,964. Cigarette-making machines. K. KÍRBER. May 25, 1964 [April 8, 1963], No. 13838/63. Heading A2C. Tobacco is fed from a belt 2 to a groove 17 in a feed wheel 1 and passed under an endless presser belt 4, then under a presser roller 11 and a trimming device 10, is formed into a rod is wrapped in cigarette paper and cut into cigarettes. When the quantity of tobacco varies the belt guide roller 5 swings on a spring urged lever 6 and a compensating roller 8 also swings on a spring urged lever to allow for variation in the length of the presser run 29 to maintain constant pressure on the tobacco. Suction is applied to the tobacco in the region between the end of the feed belt 2 and the presser belt 4 through permeability of the base of the groove. In an alternative construction the roller 5 is fixed and is close to the end of the feed belt 2 dispensing with the suction region. Variations in lengths of the presser run are compensated by a roller swinging on a spring urged lever pivoting on the axis of the driven roller 7. A presser roller in contact with the presser belt on the driven roller prevents slip between the two.
