Filed: 1947-09-09
Abstract: 651,002. Internal grinding. GUEST, KEEN & NETTLEFOLDS (MIDLANDS), Ltd. Sept. 9, 1947, No. 24715. [Class 60] An attachment for an internal grinding machine to prevent bellmouthing comprises a base or bracket adapted to be secured to the normal transverse feed slide or carriage of the machine, a body supporting the grinding tool spindle and displaceably mounted on said base or bracket for movement transversely to the axis of rotation of the spindle, and a device operable in response to the relative axial movement between the workholder of the machine and the grinding tool during entry and exit of the latter into and from a workpiece, for displacing the body so that the grinding tool spindle is moved towards the axis of rotation of the workholder. The grinding wheel 42 is carried by a spindle 24 mounted in bearings in split blocks 22, 23 on a body 20 which is pivotally mounted about a vertical axis, on a bracket 15 having a rear wall 17 secured by bolts 16 to the transverse feed slide or carriage 14; the spindle 24 is driven by a belt 26 and a domed pulley 25 secured on-the spindle, the centre of the pulley lying above the pivotal axis of the body 20. A screw 27 is threaded horizontally through the front vertical wall of the bracket 15 and bears upon a plate 28 at the back of said wall; a cam 29 is interposed between the plate 28 and a plate 30 fixed to the body 20. A plunger 40 loaded by a spring 39 bears against the other side of the body 20. The cam 29 is moved horizontally by a sliding plate 37 having an inclined face 38 cooperating with an inclined face 36 on the upper end of a vertically slidable bar 31, the lower end 32 of which is V-shaped and co-operates with a V-shaped cam 34 carried by a plate 35 adjustably mounted on the reciprocating workholder. The sliding plate 37 is loaded in a rearwardly direction by a coiled spring 51. A dial indicator may be mounted on the bracket 15 to indicate movement of the body 20. In operation, the body 20 is allowed to move to a position in which the axis of the tool spindle is. parallel to the axis of the work-carrying chuck. The slide 14 is adjusted at rightangles to the axis of the tool spindle to bring the tool spindle into correct position in relation to the hole in a finished workpiece. A fresh blank is then placed in the chuck, and the body 20 is adjusted by the screw 27 (without moving the slide 14) ta bring the tool into a position enabling it to clear the wall of the hole in the workpiece, and when the tool is within the hole, the screw is turned back to allow the tool to move until it engages the surface to be ground. Grinding proceeds, using only the screw 27 until the dial indicator registers the position which it registered when a finished workpiece was mounted in the machine and engaged by the tool. As the workholder reciprocates, the tool is moved away from the surface to be ground just before the tool leaves the hole and just before it enters the hole. Specification 651,003 is referred to.

Abstract: 860,375. Producing di-hydrodesoxy streptomycin electrolytically. RIKAGAKU KENKYUSHO. July 23, 1959 [July 25, 1958], No. 25372/59. Class 41. Dihydrodesoxy streptomycin or a salt thereof is produced by electrolysis of a salt of streptomycin or a compound thereof used as catholyte and maintained at pH 2 to 2.5 in a cell provided with a porous diaphragm between the catholyte and the anolyte which is an aqueous acid or salt solution. The potential applied does not exceed that of hydrogen deposition in the cell and is controlled to this limiting value. The catholyte is then treated with solvents, or by concentrating and crystallizing to extract the reduction products, which may be converted before extraction to a salt, e.g. hydrochloride, sulphate or phosphate. The starting material includes streptomycin, or the hydroxy- or mannosido-derivatives. The pH value is maintained at required value by adding an inorganic acid as required or a buffer salt, e.g. monobasic sodium phosphate, or sodium tartrate and citrate. Hydrolysable salts, e.g. aluminium sulphate may also be used. In the latter case the reduction product must be treated with barium hydroxide or a silver salt before concentrating the solution. The voltage is regulated by preliminary test against a standard calomel electrode. When impure streptomycin is used, e.g. 50% pure, the main reduction at the controlled pH value is followed by a short further electrolytic reduction at pH 10 to 13. As cathode, mercury, lead or zinc may be used; as anode, platinum, carbon, or lead coated with lead dioxide.
