Abstract: 517,291. Grinding, polishing, boring, milling, &c. 'GRIEVING, R. July 18, 1938, No. 21320. Convention date, April 28. [Class 60] [Also in Groups XXII and XXIV] In a grinding, polishing, boring, milling or other machine the tool is driven through continuously variable speed mechanism, means also being provided for the use of two or more speed ranges, the speed being continuously variable throughout each range.. The tool spindle 16 is mounted in a casing 1 which may be secured to a lathe &c. and is secured by bolts at 15 to a gear casing on which is mounted an electric motor 3. The motor drives, through a belt 4, a shaft 18, and the shaft 18 drives through continuously variable gearing, a shaft 24, which drives the spindle 16 by either of the belt drives 6, 7 according to the speed range required. The variable geardng, as described, comprises a cone 5 on each of the shafts 18, 24, and a slidable cone 5 mounted on each of the shafts and movable in the same direction by blocks 27, 27<1> so that as the upper cones 5, 5' move together, the lower cones move apart and vice versa, whereby a driving ring 28 engaging the cones drives the shaft 24 at variable speeds. The blocks are linked together, and one of them, 27, is moved by a rack thereon engaged by pinion 13 driven through gearing 12, 29 by a handwheel 9. The speed is indicated by a scale 10 and a pointer 31 which is moved by a follower 11 on a pivoted arm 31, the follower engaging a spiral slot formed on the rear of the handwheel 9.

Abstract: 441,535. Gear cutting. LECHESNE, G., 77, Rue Kleber, Montreuil sous Bois, Seine, France. July 29, 1935, No. 21475. [Class 83 (iii)] In a machine for hobbing worm wheels, a wheel 7 to be cut is mounted on a table 5 rotated from a driving shaft 28 by worm gearing 36 and 47, the shaft 28 also driving the cutter spindle 15 through worm gearing 34. The shaft 37 which carries the worm wheel 36 passes through a sleeve 36a carrying the worm 47 and drives the spider 37a, Fig. 3, of a differential gear, one of whose sun-wheels 37b is secured to the sleeve 36a. The other sun-wheel 37c is driven, to compensate for the axial generating motion of the cutter, by worm gearing 41 and a shaft 42 connected to a gear box (not shown), on the machine bed. This gear box also feeds the cutter slide 11 along its horizontal guides 10, for producing the axial generating motion, by means of worm gearing 50a and a screw 51. The reduction ratio of the worm gearing 36 is the same as that of the gearing produced, but the ratio of the gearing 47 is double that of the gearing produced to compensate for the increase in speed effected by the differential gear. The shaft 28 is driven by a belt from a motor 27 and carries a flywheel 29. The horizontal slide 2 carrying the work table 5 is adjusted on the bed 1 at right angles to the cutter spindle axis by means of a screw 17 hand operated at 18.

Abstract: 930,182. Wrapping apparatus. J. GAGG, and MOLINS MACHINE CO. Ltd. July 3, 1959 [July 4, 1958], No. 21487/58. Class 94(1). As packages A pass through a wrapping machine generally similar to that described in Specification 856,344, a heated element 4 is moved recurrently into and out of contact with the wrapper ends of successive packets to cause overlapping wrapper folds to adhere to each other, there being spring operated means 29, 30, 31 for moving the element 4, after a delay period, away from a package should the wrapping machine stop while the heated element is in contact with the package. As shown springs 31 continually bias to the left a piston 29 of an airtype escapement such that if the machine is at a standstill with the heater 4 in engagement with a package, a collar 28 on the piston 29 eventually engages a roller 27 to displace it and cause a linkage system 25, 19, 18 to swing the element 4 away from its operative position. Whilst the machine is operating normally, a pusher 33, reciprocated by a link 6, always acts on the collar 28 to return it to the right before it contacts the roller 27. Wrapping steps. As a packet A moves to the right over a base 1 and beneath a top plate 2, a wrapper blank that has been fed down into the path of the packet is folded into U form about it. The trailing limbs of the U are folded against the rear face of the packet first by a lower tucker (not shown) and then by an upper tucker 3, adhesive being applied between these overlapping ends. The upper tucker 3 is apertured to enable the heating element 4 to project through it. Side tuckers 5 are provided for forming side tucks, as described in Specification 856,344 above referred to.

Title: Process for the production of lactams from cyclic ketones and hydrazoic acid
Filed: 1952-08-28
Abstract: Lactams are prepared from alicyclic ketones, particularly cyclohexanone, cycloheptanone and di-cyclic ketones, by reaction with aqueous sodium azide and hydrogen chloride below 30 DEG  C.  In examples: (1) aqueous sodium azide and cyclohexanone are added simultaneously dropwise to cooled, stirred concentrated hydrochloric acid, the product diluted, neutralized and o -caprolactam extracted with chloroform or methylene chloride. Methyl caprolactam is obtained likewise from methyl cyclohexanone; (2) 2 : 2 - bis - (4 - oxo - cyclohexyl) - propane in chloroform and aqueous sodium azide are added dropwise to cooled, stirred concentrated hydrochloric acid, passing in hydrogen chloride at the same time.  Isolation of the product as in (1) yields a di-lactam of the formula <FORM:0723594/IV (b)/1> Prolonged heating of this dilactam in aqueous solution yields the corresponding diamino dicarboxylic acid.  Other examples describe the preparation of #z-penantholactam from cycloheptanone, and the di-lactam from 4 : 41-dioxo-dicyclohexyl.  Specification 701,789 is referred to.

The products give fast, easily dischargeable shades on silk.  Tetrakisazo dyes are prepared by using the urea derivatives of phenylenediamines such as p-diamino-diphenylurea, as first components in the process described above.
