Abstract: 588,487. Hinges. PAUL, P. H. Feb. 21, 1945, Nos. 4411 and 19832. [Class 65 (ii)] A readily separable hinge for a door, window, clothes horse, screen, nursery or farmyard pen which allows the elements of the structure to fold so that one element may rest flat on another consists of a link plate 5 pivoted to an angular bracket 13 through a pivot 11 and to an angular bracket by a pivot 10 which allows the hinged element 9 to be detached from the element 15 by sliding the bracket 7 off the pivot. When a pair of these hinges are used, the pivot pin 10 of one of the hinges, preferably the lower one, may be made a little longer than that of the other hinge so as to enable the pivot pins to be inserted one at a time. To lessen' the gap between the elements 9 and 15, the brackets 7 and 13 may be let into recesses cut in the elements. The pivots 11 may be part of a rod connecting the link plates 5 of a pair of hinges together so that they move together, or a separate rigid connection may be provided for this purpose. In a modification, accidental detachment of the bracket 7 from the pivot 10 is prevented by a latch 16, Fig. 2, pivoted on the bracket 7. The horizontal flange 19 of the latch has a srot which passes over a reduced portion 21 of the pin 10. The end of the slot has a circular recess into which the shoulder 17 of the pin 10 fits when the latch is in the operative position. The axis of pivoting may be horizontal. According to the first Provisional Specification, the bracket 13 may be replaced by two similar brackets with the link plate 5 mounted between the horizontal flanges 12.

Title: Improvements in method and means for distinguishing between natural pearls and cultivated pearls, termed "japanese pearls"
IPC: G02B23/24
Filed: 1926-02-17
Abstract: 247,968. Chilowsky, C., and Perrin, F. Feb. 21, 1925, [Convention date]. Optical apparatus.-Cultivated pearls are distinguished from natural pearls by observing the variations in the intensity of light received at one end of the channel of the pearl from a beam passed into the other end and reflecter into the body of the pearl, the examination being made by a similar reflector whereby the passage of light through the pearl is determined. In one arrangement, Fig. 1, a hollow needle of nickel steel carrying two mirrors b<1>, b<2> separated by an opaque material is inserted into the channel of the pearl. Apertures d<1>, d<2> are made in the needle opposite the reflectors b<1>, b<2>, and a beam of light is projected along the axis and reflected into the body of the pearl. The light received by the mirror b<2> after passing through the pearl is examined by a lens or microscope f. In the case of a natural pearl the light variation as the needle passes through the pearl is regular, whereas in the case of a cultivated pearl, having a mother-of-pearl centre, the variation of the intensity of light reoeived is abrupt when the central portion is reached. Rotation of the natural pearl on the needle produces no variation of intensity of the emitted light, but in the case of a cultivated pearl the rotation gives a variation of intensity due to the plane laminae of the central portion. The opaque portion c may be of bevelled and polished steel or silver. The needles a are mounted in a rotatable rod k supported in a frame i carried by a stand 3. The rod k is turned so that the needles are upward for the reception of the pearls, and are turned into a horizontal position for examination. Light is projected along the needle from one end and the pearl is moved along the needle by clips 5 actuated by the handle 2. The needle is rotated by a knurled disc as shown. Several modifications of the form and arrangement of the mirrors are described, in some of which the needles or rods are of transparent material and in which the mirrors are conical or arranged parallel to oneanother.
