Title: Improvements in optical testing apparatus
IPC: G01P3/40
Filed: 1943-10-07
Abstract: 571,065. Optical measuring apparatus. BURSILL, A. Oct. 7, 1943, No. 16443. [Class 97 (i)] [Also in Group XIX] In an optical measuring apparatus the variation in relative angular motion between two bodies rotating on the same axis and at the same average angular speed, is indicated or recorded by a beam of light which, by reflection from two or more mirrors mounted on the said bodies, is caused to rotate, any relative angular motion between the said bodies resulting in the radial deflection of the light spot formed by said beam of light. As shown applied to a gear train the gears D, E and F are rigidly and G freely mounted on parallel shafts and driven by a mechanical drive. The mirrors J and L are adjustably mounted on a collar H and mirrors K and M on gear G. A beam of light is passed through the hollow shaft B, the mirrors adjusted so that the beam is reflected in the order J, K, L, M, and the final beam is directed to an indicator or a photographic plate in a plane perpendicular to the original axis of the light beam. Any errors in meshing or backlash will be indicated by a radial movement of the beam of light from a datum circle obtained by locking the gears so that no relative motion may take place. The sensitivity may be increased by adjusting the mirrors L and K to give multiple reflections and also by passing the beam through the shaft on which the smaller wheels are mounted.

Filed: 1931-06-08
Abstract: 380,079. Loose-leaf binders. MOORE, W. L., Huddart Parker Building, Post Office Square, Wellington, New Zealand. June 8, 1931, No. 16639. [Class 146 (i).] A device for securing papers and the like in folders and files comprises a member formed to lie flat on the papers, and having an edge containing one or more inwardly-set portions to bear against cord sections where the latter emerge from the papers, the cord sections being attached to a backing and maintained under tension by outwardly spring-pressed grips in which the cord sections are secured near their free ends, and the arrangement allowing the normally tensioned cord sections to be slackened without releasing them from the grips. In one form the device comprises a piece of spring wire 1, Fig. 1, bent near its ends to provide bows with return portions 2, the ends of the wire being doubled close against the portions 2 to form grips 3 for the ends of cord sections 4. The back edge or main portion of the device may be set inwardly or may have a number of inwardly-set portions 6. The cord passes through holes 8 in the papers 7 and is secured to the binder or file 9. To attach the device 1 it is placed flat on the papers and one cord section is passed over it and secured in a grip 3, and the other cord section is then pulled to draw the cord tight against the spring action of the bow, and is passed over the device and secured to the other grip 3. When it is desired to loosen the device 1 to enable the papers 7 to be opened out flat, it is raised about its back edge as fulcrum, the bow portions 2 being compressed further until a position is reached where the back portion can be moved away from the cord sections, and therefore permit the papers to be opened out. In a modification, shown in Fig. 6, the main member consists of a section 10 of rigid sheet material, the back edge having a plurality of inwardly-set portions 11 and the spring grips 3 being formed on a member 12, preferably of wire, which is attached to the member 10 and formed so that the grips 3 normally tend to spring away from the back edge.
