Abstract: 977,729. Machine tool details. TECALEMIT Ltd. April 7, 1961, No. 12683/61. Headings B3B, B3C and B3T. [Also in Division G1] In a spark discharge apparatus for measuring the distance between two electrically conductive bodies cessation of current flow in a high voltage circuit including the bodies, and commencement of current flow in a lower voltage circuit including the bodies, define the upper and lower tolerance limits. The lower limit may be zero, i.e. the two bodies may be in contact. In an arrangement for setting up a tool 5, Fig. 4, relative to a master pattern 6, held for example in the chuck of a lathe, a preset spark gap SG1 connected to a tuned circuit 22, 23 in the base circuit of a transistor TR1s is in parallel with series spark gaps SG2, SG3 acros a high voltage secondary winding 17 of a supply transformer 11, the spark gap SG2 being adjustable and calibrated and the spark gap SG3 being the gap being measured. The gap SG1 is smaller than the sum of the gaps SG2, SG3 and the discharge across it at switch-on ener gizes relay A until the gap SG3 is reduced sufficiently for discharge across SG1 to cease. Advancing means for the tool 5, such as a vibrator, is connected across terminals 31-33 and is controlled by a relay B when the relay A is released to drive the tool forward until the minimum limit (in this ease contact between the tool 5 and the object 6) causes current to flow in the low voltage circuit across the secondary 25 of transformer 11. Release of the relay A is indicated by a lamp LP3 and contact of the tool with the workpiece by a lamp LP2, both lamps being energized from the secondary winding 25. A vibrator for advancing by percussion the tool during setting comprising a solenoid and an armature, the latter of which controls during its travel a microswitch to make and break the solenoid circuit, is described with reference to Fig. 5 (not shown), and the alternative use of a pneumatic vibrator is referred to. Use of a further arrangement for measuring manufactured workpieces which comprises a series of fixed probes which may be successively switched into position and which control reject mechanism is also described. The use of a master pattern 103, Fig. 6, for setting a drill, Fig. 9 (not shown), and a form tool 123, Fig. 10, for the manufacture of a part 114, Fig. 8, is also described. In the arrangement the drill wall surface clearances must be great to prevent premature ionization, i.e. before the drill is set to effect the correct penetration. An alternative stamped out form of master pattern for the same component and a collet 151, Fig. 13, whereby the pattern is mounted in and insulated from a lathe is described.

Title: Improvements in processes for the preparation of nuclear alkylated, aralkylated, andarylated derivatives of alkaloids of the morphine series
Filed: 1937-05-05
Abstract: Dihydrothebainones containing nuclear hydrocarbon substituents are prepared by treating dihydrothebaine with organo-magnesium halides in benzene solution and hydrolysing the product with acid.  Preferably, any free alkyl or aralkyl halide present in the organo-magnesium halide solution is rendered inactive by the addition of a tertiary amine, thereby avoiding contamination of the alkaloid product with quaternary ammonium compounds. According to the examples, (1) dihydrothebaine is heated in benzene solution with methylmagnesium halide, prepared by evaporating an ethereal solution to dryness, and the product treated with hydrochloric acid to give a mixture of methyldihydrothebainone and its stereoisomer; (2) the same treatment is effected as in (1), except that trimethylamine is added to the ethereal solution before evaporation.  The samples furnished under Sect. 2 (5) consist of benzyl- and phenyl-dihydrothebainones, prepared by interaction of dihydrothebaine in benzene solution with benzyl-and phenyl-magnesium chloride respectively and subsequent treatment with hydrochloric acid.
