Title: Improvements relating to installations for steel works
IPC: C21B3/10
Filed: 1962-02-19
Abstract: Slag is removed from a converter 2 in a slag bucket 14 (see Fig. 2) carried by a truck 7 which is driven by its own motor along a track 6 extending at right angles to the pivotal axis 1 of the converter and which has a lifting mechanism, e.g. comprising an arm 9 which pivots at point 8 on one end of the truck, the arm being raised and lowered by a hydraulic ram 11 and having a forked end 10 projecting beyond the other end of the truck, for raising the bucket to the converter mouth 15 when the converter tilts to pour slag into the bucket.  The arm 9 may also extend rearwardly (see Fig. 8) beyond its pivot point 8 with the rear end carrying a counterweight 25. <PICT:0962593/C6-C7/1> <PICT:0962593/C6-C7/2> The truck and bucket are preferably arranged to travel beneath the converter when the lifting mechanism is lowered.  Another truck (see Fig 3, not shown) for carrying a ladle for molten steel may also run on the track 6. The slag <PICT:0962593/C6-C7/3> bucket truck 7 may be arranged to act as a base lifting truck (see Fig. 10) for replacing the converter base in which case location means such as three circularly arranged projections 22 (shown in Fig. 8) are provided on the arm 9 for centering a second lifting mechanism, e.g. a hydraulic lifting cylinder 29 with piston 30, for use in raising and lowering a converter base 32.

Filed: 1916-05-15
Abstract: 125,100. Charmier, F. W., and Curtis, W. May 15, 1916. Projectile fuses.- Relates to percussion fuses for handgrenades, and consists mainly in the arrangement of a ball 11 or like symmetrical member centrally between two .supports 12, 17 in such a manner that the ball becomes displaced laterally on impact, and one support 17 carrying a detonator 24 is thrust by a spring 22 against a firing-pin 26. The several parts of the fuse are carried within a tube 7 with an enlargement 7<1> around the ball. The firing-pin 26 projects into the tube 7 from a clip 25, which is sprung over the tube. The support 12 is secured to the tube 7 by an indentation 7<2>. Both supports are coned to form small seats 15, 19 for the ball. The ball is held at safe by a cagle 10, which is withdrawn by a spring 16 when an external restraining-lever 28 is released, the lever being normally locked by a. pin 30 with finger-ring 31. In a modification, the support 12 is not fixed, but is pressed inwards by a spring, the pressure of which is partly relieved when the restraining-lever is released; in this case, the safety cage 10 may be dispensed with, the normally strong spring pressure of the support 12 being relied upon to prevent displacement of the ball before the grenade is thrown, whereas, on impact, this spring pressure having, been reduced, the ball can move. Reference has been directed by the Comptroller to Specification 105,932.

Abstract: 434,604. Screw propellers. JONES, W. H., 15, Peny-Fal Road, Abergavenny, Monmouthshire. March 5,1934, No. 7024. [Class 114] An automatically variable pitch screw propeller has the blades mounted on an axis inclined forwardly and the centres of pressure and centres of gravity of each blade are displaced from the longitudinal axis of the blade toward the trailing edge. Blades 1 are mounted in sockets 4 on the boss so that they have an inclination forwardly and under the disposition of the centres of gravity and centres of pressure aft of that axis, the blades take up automatically a given pitch position. The maximum pitch position is limited by a stop constituted by a member 10 against which abuts the ball end 9 of an arm 7 secured to a sleeve 15 on the blade root. This abutment or stop is held by a light spring 12, but the rod 11 carrying the stop may be adjusted manually. For this purpose a second rod 13 is provided, and between it and the rod 11 are a number of balls 14, so that the second rod need not partake of the rotary motion of the propeller.

Title: Machine for manufacturing toothed wheels, worm wheels or the like
IPC: B23F5/14
Filed: 1921-03-05
Abstract: 159,900. Wingquist, S. G. March 12, 1920, [Convention date]. Gear-cutting.-Gear generating machines of the type in which the generating motion is derived from an approximating link system are provided with means whereby the same link system may be adapted to the production of wheels of different diameters. Fig. 2 shows a link system comprising a link a fixed to the axis of the wheel C and a link b rotatable about an axis x'. fixed relatively to x and slidably and rotatably mounted at the fixed point 0 and at a. During the displacement of the line x, x<1> from A to B the wheel C will be constrained to rotate approximately as though it were rolling on the surface P. The motion of a smaller wheel such as C, over a surface P<1> may be regarded as comprising a rolling motion over a distance o<2>, o<1> and a sliding motion over a distance 0<1>, 0<SP>2>. According to the invention a lever c is pivoted at o<2> and guided at 0 and x so that during the motion from A to B the surface p<1> will be moved tangentially by a distance 0, 0<SP>2> so that the wheel C will now have a purely rolling motion on the surface P<1>. Alternatively the lever may be mounted in any position C' parallel to c and having the pivot point in the surface P<1>. By altering the position of the pivot point of the lever gears of different diameters may be generated by means of the same link system a b. Figs. 3 and 4 show an application of the invention to a machine having a reciprocating rack tooth cutter 9 for generating spur gears. The wheel blank H is secured to a table 8 rigidly -connected to a. shaft x journaled in a slide 2 having an extension forming a bearing for the shaft x' of the link b pivoted at the fixed point 0. The cutter 10 is connected by an arm 11 to the pivot 0<SP>2> of the lever c<1> and is mounted on another slide adjustable at right angles to the direction of rolling to enable the mechanism to be set according to the diameter of the blank. In operation the slide 2 is traversed to move the link b from A to B and the, reciprocating tool receives the necessary tangential motion for correct rolling from the lever c<1> through the arm 11. It is stated that the invention is applicable to the manufacture of worm wheels or bevel gears. The Specification as open to inspection under Sect. 91 (3) (a) states also that the invention may be applied to other approximating link systems. This subject-matter does not appear in the Specification as accepted.

The plate 13 is attached to a coupling flange 16 provided on the propeller shaft 17 for connection through a resilient disc 20 to a gear-box output shaft. The natural frequency of the damper is determined by the length of slits 22 formed in the rubber element 12 near the corners of the plate 13, and by the size of holes 25 in the element 12 which also permit the passage of tools for tightening screws which secure the resilient disc 20 to the gear-box output shaft. The rubber layers 24 on each side of the slits 22 serve as abutments for limiting radial run-out of the annular mass 12.
