Title: Improvements in and relating to tracer-controlled machine tools
IPC: B23Q35/121
Filed: 1954-06-03
Abstract: 766,013. Copy-milling. SCHMID, W. K. June 3, 1954 [June 3, 1953], No. 16456/54. Class 83 (3). [Also in Group XXIII] A copying machine comprises an electric tracer 13, Fig. 1, controlling means 9, 11 for moving superposed slides - in different directions and means 20 associated with one of the slides to rock a workpiece 14 on one of the slides. The plane sheet template 12 is mounted on the table 7 moved longitudinally by the magnetic reversing clutch 9 and transversely by a similar clutch 11. The axially-adjustable milling-cutter or grinding- wheel 3 is mounted in a head 2. The work is rocked on a shaft 15 by rack-and-pinion gearing 19, 20 as the table moves transversely to or from the cutter. In a modified work-mounting, the work 14, Fig. 2, is rocked by gearing adjustable in a box 28 by hand means 32, 33 to enable different radii to be cut, the gearing being driven by a shaft 31 from the magnetic-clutch 11. The fixed tracer 13 is of the same diameter as the tool and follows the path indicated in Fig. 4. The tracer first operates on a sequence indicated in Fig. 6a until the point C is reached, at which time a limit switch 25 is actuated by an abutment 24 on the table 7 and the sequence changed to that shown in Fig. 7a. At D, a time-delay switch operates and a further change occurs so that tracing is completed on sequence III, shown in Fig. 8a. The tracing sequences are determined by the circuit connections to four relays controlling the forward and reverse movements imparted by the clutches 9, 11. The circuit connections are altered to change from one sequence to another by a contact cylinder, Fig. 9, advanced by an electromagnet M controlled by the switch 25. In a modification, movement of the tracer causes movement of a brush 48, Fig. 13, along a stack of metal lamellµ 49. The slides are controlled according to which one, or adjacent pair, of the lamellµ are in contact with the brush. To change to a second tracing-sequence, the brush 48 is rendered ineffective and a second brush 62, displaced from the first, is used. For a third sequence, the brush - 48 is again used but connections for the relays are crossed. In further modifica. tions, the switch. over from one sequence to another is obtained by further contacts actuated by the relays.

Abstract: 1,216,997. Epoxy compounds. PETROCARBON DEVELOPMENTS Ltd. 8 April, 1969 [5 April, 1968], No. 16577/68. Heading C2C. Propylene oxide is produced by oxidizing isopropanol in the liquid phase with oxygen or an oxygen-containing gas at elevated temperature and a pressure sufficient to maintain the isopropanol and the reaction product (comprising unreacted isopropanol, hydrogen peroxide and acetone) in the liquid phase, removing the acetone from the hydrogen peroxide and unreacted isopropanol, reacting the hydrogen peroxide with a solution of urea to give a precipitate of an adduct of urea with hydrogen peroxide in the molar proportion of l:1, mixing this adduct with an extracting solvent which is an alkyl ketone with up to 7 carbon atoms; an alkyl ester with up to 7 carbon esters or an alkyl (C 1 -C 4 ) orthophosphate thereby dissolving the hydrogen peroxide and leaving at least part of the urea in solid form, replacing or mixing the solvent in the resulting hydrogen peroxide solution with one or more carboxylic acids of formula RCOOH, in which R is hydrogen, phenyl or a C 1 -C 5  alkyl radical optionally substituted by at least one electrophilic group in an inert solvent, thus producing a percarboxylic acid solution, removing any water present in the remaining peracid solution by azeotropic distillation and reacting the resulting anhydrous percarboxylic acid solution with propylene to give the required propylene oxide, the process being carried out in the absence of heavy metal ions. Suitable inert solvents are, for example, n-propyl acetate, benzene, ethyl acetate, toluene and xylene. If desired, the reaction may be carried out in the presence of an initiator, e.g hydrogen peroxide or azobisisobutyronitrile.

Title: An improved method of and apparatus for the manufacture of the actuating pinions of the tens transfer mechanism of counting apparatus
IPC: B21K1/30
Filed: 1945-06-29
Abstract: 595,654. Making toothed gearing. LANDIS & GYR SOC. ANON. June 29, 1945, No. 16639. Convention date, July 5, 1944. [Classes 83 (ii) and 83 (iv)] Forging-dies.-In a method of making a tens transfer actuating pinion for a counting mechanism, an aluminium rod is upset and partly pierced in a die having the superficial shape of the required pinion, in a second die the teeth are trimmed, the closed end is pierced and the other end partially closed in to form two bearing apertures and in a third die the blank is formed to the precise length required and the bearings are trued to the required bore. If desired, the rod may be given a preliminary pressing to shape one end to approximately conical form. The coned or plain blank is placed in two dies 3 and 4 forming the shape of the pinion. The upper die 4 has a central passage 8 in which operates a piercing- punch 11 having an enlarged head 12 to upset metal into the pockets 6 and 9 of the die, which are in the form of the teeth 7 and 10, Fig. 5, of the pinion. As the punch is withdrawn the metal that tended to close in behind the head is forced out particularly into pockets 9 and the bearing extension 13 is formed. The rough pinion is now seated on a recessed lower die 16 and pressed through a toothed cutter 15, Fig. 3, by a toothed punch 14 against the action of a spring 23. The punch 14 has concave shoulders 18 at its lower end and carries a central pin 19, The open end 13 of the pinion is first closed on to the centre punch 19 by the shoulder 18 after which punch 19 perforates the closed end forming a bearing aperture. Further downward travel of the punch brings its teeth into engagement with those of the pinion whereby the pinion is forced into the cutter 15 and the fin b is removed and the teeth trimmed. In the final operation the conical end of the pinion is fitted in a mandrel 24 having a centre gauge pin 25 to locate in the bearing aperture. A punch 27 has a mandrel 28 with an enlarged end 29, and a shallow depression surrounding the base of the mandrel. On relative movement towards each other of the punch and holder the mandrel 28, 29 enters the second bearing hole in the drawn end 13a and this end is further upset and forced against the mandrel. This compression gives the pinion the required overall length. The bearings are aligned and given the correct bore at one end by the gauge pin 25 and as the holder is cleared from the punch the head 29 forms the correct bearing aperture at the opposite end.
