Title: A process for the production of concentrated solutions of alkali cyanides
IPC: C01C3/10
Filed: 1925-12-23
Abstract: 245,152. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. Dec. 23, 1924, [Convention date]. Alkali cyanides. - A concentrated solution of alkali cyanide is produced by passing hydrocyanic acid into an aqueous mixture of an alkali sulphate and lime while preventing the deposition of a double salt of calcium and alkali sulphate, for instance by keeping the temperature at 15‹ C. or lower. The temperature may be raised somewhat towards the end of the reaction or afterwards to bring into solution any undissolved alkali cyanide. The whole of the reagents may be present at the beginning, or portions may be added during the progress of the reaction. Specifications 4513/03, 174,364, and 268,420 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes a modification in which the production of the double salt is prevented by keeping down the concentration of the alkali sulphate, in which case it is not necessary to keep the temperature low. The reaction mixture may contain the whole of the lime and a part of the alkali sulphate, the rest of the alkali sulphate being added during the reaction. The subsequent addition of alkali sulphate may follow upon the production of some calcium cyanide. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,150,305. Abrading. LA SOUDURE ELECTRIQUE LANGUEPIN. 20 July, 1966 [20 July, 1965], No. 32520/66. Heading B3D. A method of machining using an abrasive tool 38 in the form of an imprint 39 of the workpiece 40 to be obtained with the plane parallel sections of the tool exactly the shape of corresponding plane parallel sections of the workpiece to be produced but differing by a constant quantity, comprises pressing the workpiece against the tool in a direction perpendicular to the sections, and moving the tool in relation to the workpiece with an alternating movement of constant amplitude, the direction of which continually turns in relation to the tool and workpiece which retains the same relative orientation. The tool 38 consists of a matrix having a cavity 39 corresponding to the shape of the workpiece to be produced, the side-walls of the cavity being abrasive. The tool is secured to a platform 7 which is supported by balls 8 between flat slide-tracks 9, 10 on a table 1 carried by pillars 3 from a base 1, the platform being prevented from turning relative to the table by springs 11 placed tangentially to the platform between posts 12 and pins 13, but being movable in translation. A spindle 15 mounted in a bearing 14 depends from the platform and is secured to a vertical rectangular frame 19, one end of which is joined to an electromagnetic vibrator 20 fixed to a bracket 22 of adjustable length on a second platform 23, and the other end of which has an extension 24 slidable in a block 25 also mounted on the platform 23. The platform 23 is adjustably secured to a hub 28 of a worm-wheel 29 engaged by a worm 30 driven by a motor 31. The workpiece 40 which may be of copper, aluminium, mild steel or graphite is mounted on a carriage 6 vertically movable on pillars 4. The workpiece may be pressed against the tool by additional weights or to reduce the pressure of its own weight a spring or compressed air device 42 may be provided. When the vibrator 20 is energized, the platform 7 carrying the tool is reciprocated on the table 1, and the rotation of the platform 23 by means of the worm drive causes the direction of reciprocation to be moved around the axis of the platform 7. In another embodiment, the platform 7 is maintained parallel to itself by means of pantographs or cross-slides. The direction of vibration may be curvilinear.

Title: Improvements in and relating to machines for working or conditioning leather or skins
IPC: C14B1/10
Filed: 1953-11-24
Abstract: 741,916. Leather working machines. SOC. MERCIER FRERES. Nov. 24, 1953 [Dec. 19, 1952], No. 32597/53. Class 76. In a leather working machine of the type having a worker roller and a drive roller which co-operates with and drives a feed roller when the latter is in operative position, the feed roller being movable towards or away from the worker roller, a supplementary work-supporting device in the form of an endless belt is provided to engage the workpiece about a sector of the worker roller, the said belt either being the sole work-engaging means, or operating in conjunction with the feed roll which also engages the work with the worker roller, the belt in each case being driven through the feed roll by the drive roll. As shown in Figs. 3 and 4, the machine comprises a worker roll 6 having blades 7 thereon, a spring-loaded drive roller 13 and a feed roll 25. The latter moves from the inoperative position (Fig. 3) to the operative position (Fig. 4) on an arm 28 pivoted at 29 under the action of toggle links 30 and 31. These links are operated by an arm 35 associated with an eccentric 36 which rotates half a turn to bring the feed roll 25 into or out of operating engagement. The supplementary work-supporting device consists of an endless belt 56 passing around a support roller 55 and an adjustable roller 57. Both of these rollers carrying the belt are supported on an arm 52. The latter is pivoted at 50 to an extension of the arm 28 carrying the feed roll and also at a pivot 60 about which the arm 52 turns when the feed roll arm 28 moves. The pivot 60 is in turn mounted on an arm 61 which moves on an eccentric pivot 63, this eccentric being movable to predetermined positions by a lever 65, thus providing an adjustment for the final position of the lower roller-bearing end of arm 52 when the latter is carried forward to the operative position by the movement of the feed roller supporting arm 28. In Fig. 10 an arrangement is shown wherein the feed roll 25 in the operative position engages and is driven by drive roll 13, but does not itself bring the work in contact with the feed roll 6. The endless belt 56a is again supported by rollers 55a, 57a (corresponding to 55 and 57 in Figs. 3 and 4), but in this case the belt may be driven in the same or opposite direction as the feed roll 25 by means of an alternative drive either directly by a sprocket chain 74a or through a sprocket driven idler gear-wheel 78 which meshes with a gear-wheel on roll 67a. A further alternative is shown in Fig. 11 where the endless belt passes over the feed roll 25 and a support roll 55b, the latter being carried on the arm 52b as before The blades 7 of the worker roller 6 may be of helical pattern as shown in Fig. 5, or alternatively they may have a corrugated edge seen in side elevation.

[Class 37] In a mechanically-operated press-button tuning system of the kind in which depression of a push-button lever brings a cam-locating member into contact with a pivoted shaft connected to the rotor element of a tuning system so as to move the latter to the required tuning position, the cam-member comprises a three-limbed star 23 provided with a recess 24 coacting with the pivoted shaft 18 connected to the tuning devices. The member 23 is pivotally mounted by one of its limbs on the end of a push-button lever 19. Fig. 3, which is pivoted on a fixed axle 20 parallel to the front of the receiver. The front 21 of the lever consitutes the push-button and is provided with an aperture 22 behind which a station name is displayed, while the rear end is formed with a bracket 33 carrying a sound-absorbing rubber buffer 3,4. Micrometer adjustment of the member 23 is effected by means of a rod 26, one end of which is screw-threaded and passes diametrically through a stud 25 freely pivoted on the member 23. The other end is located in a hole in a bracket 27 formed integrally in the push-button rod 19 and is provided with a knurled wheel 28 by which the rod is rotated to adjust the exact position of the member 23. The latter is located in respect to the lever 19 by a spring 29. The lever 19 is held in the depressed position by a spring latch-bar 30 depression of which effects release of any other lever which may be in the operative position. An arcuate slot 35 is formed in the lever 19 through which projects the end of a switch arm effecting muting of the loud speaker. One of the push-buttons is adapted for manual tuning by connecting the knurled wheel 28 through a rubber-tyred wheel (Fig. 5 not shown) to a manual tuning knob, In the modification shown in Fig. 6 the locating member 59 is provided with a semicircular recess 61 to engage the rotor-spindle operating-means and with a forked arm which engages a grooved collar 57 on the threaded part of the push-button rod 53. The member 59 is pivoted on an upright lever 50 pivoting in a support 51 and is moved inwardly on depression of the rod 53 which engages on a projection 52 on the lever. Adjustment of the collar 57 is obtained by rotating the knurled knob on the push-button 55.

Title: Improvements relating to travelling furnace-grates
IPC: F23H11/00
Filed: 1932-11-22
Abstract: 403,216. Furnace grates. SCHENK, E. M. F., 5, Missundestrasse, Altona, Elbe, Germany. Nov. 22, 1932, No. 32990. [Class 51 (i).] In a travelling grate formed with relatively movable overlapping scale-like members, the upper run of the grate moves from the rear to the front and the overlapping members are oscillated so as to impart to the fuel a stepby-step movement from the front to the rear. In one form Figs. 1, 2, 3 and 10, the grate comprises overlapping pusher members 5, 6 pivoted through links 9 to shafts 8 extending between the links 7 of inner and outer chains at each side of the grate. Alternate members 5 are connected through links 20 to rocker arms 10 each mounted on the respective shaft 8 and formed with a finger 14, a toothed segment 15 and keyed to a cam 12. The other alternate members 6 are similarly connected to arms 11 each formed with a finger 17, and nose 18 and keyed to a toothed segment 13. The relative position of the arms is such that cams 12 and noses 18 are in the same plane and that the toothed segments 13 and 15 are in the same plane and, in the upper run of the grate, interengage so that if one member 5 moves forwardly the co-operating member 6 moves rearwardly. As the co-operating members pass over the front driving sprocket drum 26 the distance between shafts 8 increases and the toothed segments disengage. At the same time the fingers 17 are engaged by abutments 28 on the drum and fingers 14 by arms 27 arranged to rotate at one and a half times the speed of the drum, by which engagements the cam 12 is moved over the nose 12 to lock the arms 10 and 11. The lower run of the grate is supported by rollers so that the locked fingers 14 and 17 of the lower run engage and move the free fingers of the upper run, which movement reciprocates the grate members 5 and 6 as shown more particularly in Figs. 1-3. Unlocking of the arms is effected by engagement of the fingers 14 between pairs of lugs 30, 31 on the rear drum 29. The distance between the upper and lower runs of the grate is increased from front to rear so that the distance of reciprocation of the grate members and consequently the rate of travel of the fuel is a maximum at the front of the grate and tends towards zero at the rear. Some of the grate members are formed as pans 62, Fig. 5a, adapted to collect ash and convey it to the front of the grate for disposal. In a modified form, Fig. 13, grate chains 34 carry reciprocating and relatively stationary members 33, 32 arranged alternately. From the reciprocating members depend arms 38 adapted to be engaged and actuated by a control chain 39 driven intermittently. The height of the shaft carrying the rear control chain supporting sprocket is adjustable in order to vary the distance between the chains in the upper run and consequently to vary the movement of members 33 and the rate of movement of the fuel from the front to the rear.
