Title: Compositions comprising synthetic rubber and anacardic materials
IPC: C08L11/00
Filed: 1947-08-07
Abstract: A composition of matter comprises neoprene and a hydrocarbon ether of an anacardic material, which is defined as either cashew nut shell liquid or a distillate from such liquid.  The ethers may be the methyl, ethyl, propyl, butyl, amyl, secondary propyl, secondary butyl, secondary amyl, tertiary butyl, tertiary amyl, phenyl, benzyl and allyl ethers of the material, and may be made by the methods described in U.S.A.  Specifications 2,181,119 and 2,240,034.  The distillate may be obtained by gas-, vapour- or steam-distillation under reduced pressure to give a product comprising a phenol having more than 13 carbon atoms.  In examples the ethers are added to the neoprene on a heated mill together with zinc oxide, magnesium carbonate, stearic acid, carbon black and an accelerator, the product then being cured.

Title: Improvements in chucks
IPC: B23B31/12
Filed: 1929-07-12
Abstract: 330,169. Emrick, G. W. July 12, 1929. Chucks for drills or other tools comprise a member 12 having cylindrical bores 14 carrying jaws 15, the member being in screw threaded engagement with a ribbed casing 9. An extension 6 of a taper spindle 5 enters a flanged member 7 rotatable with respect to the casing 9 and capable of small lateral and longitudinal movements therein, centring of the spindle with respect to the jaws being effected by an extension 18. A sleeve 19 engaging the square threaded portion 11 of the casing with allowance for small lateral movement, exerts pressure through balls 24 on flattened upper surfaces of cylindrical portions 15a of the jaws, the portions being retained in apertures 25 in a sleeve 21 whose upper end is spun over into a groove 20 in the sleeve 19. That portion of the member 7 within the sleeve 19 is square in shape and, on rotation, operates the jaws by engaging shoulders 26<a> on the sleeve 19. Sudden rotation in the reverse direction gives a blow to the sleeve 19 to effect release of the frictional engagement of the threads.

Abstract: 1,217,385. Holograms. HOLOTRON CORP. May 10, 1968 [May 12, 1967], No.22295/68. Heading G2J. In a method of forming an image of a non-diffuse transparent object a beam of coherent light is passed through a phase modulator placed in close proximity to a coincident with the object and then through the object whereby the beam passing  through the object has a constant amplitude and random phase. The method may be used to form a hologram, wherein a beam of coherent light 13 passes through a phase modulator 27 and the transparent object 15 and impinges upon a detector surface 17 where it interferes with a reference beam 19. The phase modulator may be a sheet of anti-glare glass polished flat on one side, a sheet of glass in which shallow etches have been provided or on which a coating has been formed. It is located as near as possible to the object so that the scattered light rays do not interfere with themselves before passing through the object. Alternatively the beam of whereat light may be passed through the phase modulator 27 and using an optical system an image of the modulator 27a is formed coincident with the object 15. To determine the focal plane of an imaging system, the beam of light is passed through a modulator and the object, a suitable optical system producing a grain free image and two out of focus graining images, the focal plane of the system being determined by the position of the grain free image. In a further embodiment a series of modulators each of known but different band width is used and those producing grain free images determined to calculate the frequency response of the system.
