Abstract: 563,812. Making tearing lines on metal &c. EASYCANTOP, Ltd., and WALENSKY, B. Jan. 28, 1943, No. 1470. [Class 100 (ii)] [Also in Group XXII] In a device for forming weakened lines in ends or lids for containers or in blanks or sheets of metal or other material therefor, the scoring knife 4, or the anvil 13, or each, is mounted so as to assume automatically parallelism between knife and anvil when pressed together. As shown, the knife 4 is mounted on a spherical support 3 centred at c in the plane of the edge 8. The lids 23 in recesses 25 in an intermittently rotated disc 24 are carried thereby over a table 26 till they reach a recess 27 therein containing a spring-raised work support 17. The anvil 13 then makes its operative stroke and returns, the lid 23 being lifted into the recess 25 by the support 17 so that at the next movement of the disc 24 the scored lid is carried on. The table 26 may have a second recess through which the scored lids are discharged. The anvil may be adjusted by a fine-pitch screwthread 10 or such a screw may be used for an adjustable stop for the anvil. In a modification the spherical bearing is replaced by two superposed cylindrical bearings with their axes at right angles or the necessary freedom is obtained by a spring or other resilient mounting. The knife and anvil are mounted so that they can be easily replaced when worn. If desired, a clamping device may be used to fix the free tool after parallelism has been obtained by bringing the tools into direct contact. Specification 556,334, [Group XXII], is referred to.

Filed: 1921-01-10
Abstract: 157,935. Schwanda, J. April 7, 1919 [Convention date]. Padlocks; lock mechanisms; slider-type. - A shackle 4 has a series of notches 3 which are engaged by sliding tumblers 5, 6, 7, 8, supported in the slotted two-piece frame 13. The tumblers have bosses 15 which guide them in the frame tumblers 5 and 7 sliding in one direction and tumblers 6 and 8 in the other when operated by the key 12. Each tumbler has a pair of unequal recesses 9 and 10. The right hand recesses 10 in tumblers 5 and 7, and the left hand recesses 9 in tumblers 6 and 8, are large enough to admit the shackle leg with a small amount of play, while the other recesses are cut longer. The tumblers are actuated by springs to cause the inner edge of the larger slot of each, to abut on the leg o: the shackle, causing the edge bounding the shorter slot to enter the notch 3 and lock the shackle to the casing 1. When the appropriate key 12 is inserted and turned, the tumblers slide in their correct direction through a predetermined distance, to face the notches 3 and allow the shackle to be removed, as shown in Fig. 2. If a key with bits too large or too small be used, the tumblers are not disengaged from the notches 3 and the shackle cannot be removed. Fig. 5 shows the invention applied to a hasp lock, the hasp 16 having slots 18 on each side. In this case, the tumblers are held in the position to release the hasp, when operated by the key, by pawls 19 engaging notches 20. To lock the hasp the key is inserted and turned partially in the reverse direction for operating the tumblers, wher it rocks arms 21 to release the pawls 19 from the nctches 20 by means of pins 22. The Specification as open to inspection under Sect. 91 (3) (a) comprises a modification, shown in Fig. 6 (Cancelled), in which the slots in the tumblers are of equal size, but the corresponding pairs of notches 3 in the shackle legs are of unequal depth. The two parts of the tumbler frame 13 are cranked and the edges 26 of the slots in it are bent to form tumbler guides. Each tumbler spring is shown housed in the space formed by cutting away a portion of the side of the tumbler. This subject-matter does not appear in the Specification as accepted.

Abstract: 1323843 Corrugating J J ROBINSON 14 Jan 1972 [1 Feb 1971] 1840/72 Heading B3E A metal strip corrugating apparatus comprises a pair of dies 48, 58, Fig. 4, both mounted for vertical reciprocation and the lower die is also capable of horizontal reciprocation to effect feeding of the strip. The upper die 58 is mounted on a frame 34 which carries rollers 32 while the frame 37 for the lower die 48 carries rollers 31, which rollers engage the sides of a pair of longitudinal members 22 of a reciprocable rectangular frame 19-22. The rectangular frame is driven by a crank arm 28, Fig. 2, through a link 31 and slides on rails 24. The rectangular frame carries rollers 92 or abutments which engage a bar 83 and lugs 89 or a rod 84 at the ends of its stroke. The bar 83 and the rod 84 extend through side plates 11 of the apparatus to linkages for effecting the horizontal reciprocation of the lower die 43. Each linkage includes a latching member 96, Fig. 6, which engages an arm 99 to hold it in position when the bar 83 moves away from it under spring bias 91, Fig. 2. The latching member ensures that the dies 48, 58 are not moved relatively horizontally during movement of the rectangular frame 19-22 which effects the vertical reciprocation. In operation the strip 121, Fig. 10, is fed between the dies 48, 58 while both dies are in their lowermost position. The upper die 48 is kept stationary while the lower die 58 is raised to corrugate the strip. The tipper die is then raised, Fig. 12 (not shown), and the lower die is moved horizontally to effect a feeding stroke. With the lower die raised the upper die is lowered to effect a further corrugating stroke, Fig. 14 (not shown). The lower die is then lowered and returned horizontally while out of engagement with the strip. The longitudinal members 22 each have areas of dwell, A, B, C, Fig. 10, to ensure that the dies move separately and not simultaneously. The corrugations may be angular.

Title: Production of intermediates in the manufacture of hormones
Filed: 1938-01-20
Abstract: Methyl - (cyclopentanodimethylpolyhydropolyoxyphenanthrene)-ketones are prepared by subjecting compounds having a cyclopentano-polyhydrophenanthrene skeleton substituted by more than one hydroxyl group or by more than one group which can be transformed into a hydroxyl group and having on the carbon atom 17 a side chain of the form <FORM:0495156/IV/1> (where n stands for a whole member starting from 0 and R stands for H or alkyl) to a degradation treatment which comprises treatment with a Grignard reagent, decomposition of the Grignard complex, acylation of the nuclear hydroxyls, and oxidation.  This process to be repeated n times until the side chain assumes the form -CO-CH3. If any nuclear double bonds are present they are protected by the addition of halogen or halogen hydride prior to the oxidation.  In an example, Cholic acid is methylated, the ester is treated with magnesium methyl iodide, and the Grignard complex decomposed to yield dimethyl - 3 : 7 : 12 - trioxynorcholyl carbinol.  This is then acetylated with acetic anhydride in pyridine solution and the acetate oxidized with chromium trioxide.  From the neutral portion of the oxidation product the ketones are removed by means of Girard's reagent (trimethyl - acethydrazide - ammonium chloride).  The acid portion on recrystallization yields nor-cholic acid.  This is subjected to a repeat treatment as above to give bisnorcholic acid, which is also in turn subjected to the same process to give 3 : 7 : 12-triacetoxy-pregnane-20-one.  Specifications 431,165, 442,319, and 443,964 are referred to.
