Title: Improvements in shears for cutting thick metal sheets
IPC: B23D31/04
Filed: 1965-11-26
Abstract: 1,085,778. Shearing. SCHLOEMANN A.G. Nov. 26, 1965 [Dec. 9, 1964], No. 50286/65. Heading B3W. In a crank-operated shear which is one of a pair arranged to trim the opposite edges of metal plates and which has a fixed lower blade and a movable upper blade, the upper blade is mounted in a blade holder which is free to slide or pivot in the upper blade beam so that the cutting blade can move in a direction away from the cut edge of the plate during the return stroke in order to relieve the pressure between the cutting blade and the cut edge. The upper cutting blade 22 is mounted in a holder 21 of trazoidal cross-section which is seated in a correspondingly shaped recess in the blade beam 5. The means for attaching the holder to the beam comprises a bolt 23, Fig. 3, projecting from each side of the blade beam and having slidably mounted thereon a shackle 24. A block 25 slides in a slot in the shackle, is biased by discsprings 27 towards the bolt 23 and has a bore which receives a pin 26 which is secured in the blade holder 21, Fig. 2. The springs 27 normally hold the blade-holder against the face A of the blade beam but the force exerted by the springs is less than the force due to the friction between the cutting blade and the cut edge of the plate so that during the return stroke the blade-holder moves away from the face A and slides down the face B. To facilitate the removal of the blade holder each shackle 24 has a projecting hook 29 which in the uppermost position of the blade beam is engaged by a forked member 31 provided with a pin 30. The forked member 31 is mounted on the piston rod 32 of an hydraulic cylinder 33. Admission of fluid to the rod end of the cylinder moves the forked member 31 and with it the shackle 24 off the pin 26. The shackle 24 slides along and is supported by the bolt 23. In a modification the blade beam (40), Figs. 4 and 5 (not shown), has a semicircular recess therein which houses an axle (42). The blade-holder (45) also has a semicircular recess (46) which engages the projecting half of the axle (42). There is a wedge-shaped gap between the blade-holder and the blade beam on the side remote from the cutting blade (49) so that during the return stroke the blade-holder (45) can rock against the force of a compression spring (50). The axle (42) is secured to the blade beam by shackles (44) and the blade holder is secured to the axle (42) by brackets (47).

Title: Rotation sensing apparatus
IPC: H01S3/08
Filed: 1964-12-11
Abstract: 1,080,379. Lasers. SPERRY RAND CORPORATION. Dec. 11, 1964 [Dec. 18, 1963], No. 50505/64. Heading H1C. [Also in Division G1] In a ring laser rotation sensor, the phenomenon of " mode pulling " is avoided by making the counter rotating light beams of different wavelength, using Zeeman splitting. A He-Ne laser tube 1, energized by A.C. or D.C. applied to terminals 8, 9, is surrounded by a permanent magnet 10. Two oppositely sensed circularly polarized beams separated in wavelength by the Zeeman splitting of the emitting atoms emerge through the antireflection windows 3, 4. The beams emerging from window 4 are converted by a quarter-wave plate 16 to orthogonally plane polarized beams one of which is preferentially transmitted by the Brewster polarizer 18. The beams then pass by way of mirrors 14, 13, 12, 11, Brewster polarizer 17 and quarter-wave plate 15, back to the laser tube 1. The same beam is preferentially transmitted by the polarizer 17 and it is only this beam that is sufficiently strong to sustain laser action. By a similar process, only the beam at the other wavelength can traverse the ring in the opposite direction. The two circulating beams are extracted by the semi-transparent mirror 14 and heterodyned to produce a signal from photo-detector 25 at the frequency of the Zeeman split, modulated in frequency in accordance with the rate of rotation of the ring. The ring is preferably square.

Abstract: 1,207,680. Preparation of alcohols. HALCON INTERNATIONAL Inc. 7 Nov., 1967 [14 Nov., 1966], No. 50541/67. Heading C2C. The preparation of alcohols by pastial oxidation of a saturated hydrocarbon in the liquid phase with molecular O 2  in the presence of a boron compound capable of forming an ester of the alcohol, whereby a reaction product containing borate ester or esters of the alcohol and hydroperoxides (i.e. any organic compound containing a peroxy oxygen atom) is obtained, from which the alcohol from said ester or esters is recovered, is improved by maintaining the reaction product at 125-200‹ C. for at least 5 mins., after the O 2  flow has ceased and before processing to recover the alcohol. The "heat soaking" step decomposes the hydroperoxides and increases the yield of alcohol. In examples, batch-wise and continuous processes wherein cyclohexane is oxidized to give cyclohexanol with by-product cyclohexanone, in the presence of metaboric acid are described. The oxidation reactions were carried out at 165‹ C. and 125 p.s.i.g., the "heat soaking" being at the same pressure and at 165‹ C. for 30 or 100 mins at 175‹ C. for 20 or 30 mins., at 125‹ C. for 120 mins., at 150 ‹ C. for 60 mins., and at 200 ‹C for 10 mins.

Filed: 1964-12-17
Abstract: A free-flowing moulding composition comprises expandable beads of a styrene polymer, from 0.33 to 3.0 parts by weight, per part by weight of expandable beads, of a non-expandable thermoplastic resin powder having a density greater than that of the expandable beads, and from 3 to 40% by weight, based on the weight of the expandable beads, of retained water in the form of a hydrate containing at least 25% by weight of chemically bound water. By "styrene polymer" is meant styrene homopolymers and copolymers containing at least 50% by weight of styrene.  The preferred amount of thermoplastic resin powder is from 0.67 to 1.50 parts by weight per part beads.  The composition may contain not more than 20% by weight, based on the weight of the beads, of an inert drying substance.  Many thermoplastic resins are mentioned, polyethylene being the preferred one.  Many hydrates are mentioned, sodium silicate and sodium tetraborate being the preferred ones.  The composition may be used in a process where it is placed in a heated mould and moved in a source of heat so that the denser non-expandable thermoplastic resin moves to a position against the mould walls and fuses against them to form an external coating, the polystyrene beads foaming and fusing together and to the coating. The function of the hydrate is to provide water which is converted into steam and acts as a heat distributing agent to ensure uniform heating of the beads.  In the examples ethylene-ethyl acrylate copolymer and ethylene-vinyl acetate copolymer are used as non-expandable resins.
