Title: Self-Aligning Slit Mechanism
IPC: G01J3/04
Filed: 1967-05-19
Abstract: 1,185,085. Optical slit diaphragms. PERKINELMER CORP. May 19, 1967 [June 17, 1966], No. 23459/67. Heading G2J. A variable slit mechanism comprises one or two slits each defined by a fixed jaw 16, 17 and a variable position jaw 18, 19 the latter jaw(s) being connected to an actuator by way of a slippable connection. Operation of jaw 18 will be described in detail. An actuating arm 44 is moved clockwise (as seen) so that the edge portion 24<SP>1</SP> of a right angled bracket 22 on which the jaw 18 - e. g. a razor blade - is supported meets a limit pin 60 and is arrested thereby before rotation of the arm, which is following a cam 12, ceases, slippage occuring between the arm and the bracket. Subsequent movement of the arm 44 anti-clockwise moves the jaw 18 towards the jaw 16 which is a mirror surface of a prism 14, until the leading edge 20 of the jaw 18 presses against spacers 62, (64 Fig. 2 not shown), on the mirror. This stops movement of the bracket 22 and also causes the edge 20 to become parallel to the jaw 16 since the jaw 18 can pivot against magnetic attraction about a pin 28. The arm 44 is moved further counter-clockwise to a particular standard position, slippage occurring between the arm and the bracket, thus establishing a standard relationship between the bracket 22 and the arm 44. Subsequent clockwise rotation of the arm 44 in accordance with the contours of the cam 12 gives a predetermined variation in the width of the slit formed by the edge 20 and its reflection in the mirror surface of the prisms. Simultaneous identical variation in the width of the other slit is obtained by the action of a plate 144 driven by the arm 44 on the bracket 23.

Abstract: 728,002. Electromagnetic relays. ENGLISH ELECTRIC CO., Ltd. Sept. 18, 1953 [Sept. 19, 1952], No. 23566/52. Class 38 (5). A frequency responsive relay which may be adapted to operate for under frequency or over frequency conditions comprises a magnetic core 1 having three pairs of poles a, b, c, d, and e, f, the outer pole pairs being shaded by windings 3 connected in series with a capacitor 4, a tapped inductor 5 being included in the shading circuit of the pole pairs c, d. The core 1 is energized by a winding 2 and the pole pairs a, b, and c, d, produce oppositely-acting torques on an aluminium disc 6 rotatable on a shaft 9 between the pole gaps, the two torques being equal when the frequency is normal, e.g. 50 c.p.s. The shading circuit of pole pair a, b, is tuned for a frequency below normal, e.g. 40 c.p.s., whereas the shading circuit of pole pair c, d, is tuned for a frequency above normal, e.g. 55-65 c.p.s. Hence in an under frequency relay, Fig. 2, or an over frequency relay, Fig. 3, a contact arm 8 on the shaft 9 is moved against a return spring 7 to bridge a pair of contacts 10 in response to under frequency or over frequency conditions, respectively. Graphs (Figs. 4, 5, not shown). show the operating torques of the shaded pole pairs plotted against frequency.

Abstract: 381,667. Combination locks. KAMINSKI, S., 4, Briennerstrasse, Munich, Germany. Aug. 21, 1931, No. 23587. [Class 44.] In a combination lock in which each disc tumbler 1 is operated by a separate number disc 4, the tumblers have dummy gatings 50 of different depths, in addition to the true gatings 51. The bolt 2 may be retracted by a knob 12 when the true gatings are aligned with projections 2b on the bolt. The number discs may be coupled with the tumblers by pins 7 fitting loosely in holes 8 so as to allow of idle movement of the number discs, or the number disc spindles 5 may be of polygonal cross section. The number discs may be taken off and the combination changed by moving slidable fastenings 11 so as to release the spindles 5. Springs 27 engage the gatings so that the tumblers are held in definite positions. The bolt 2 may be provided with a resiliently mounted tongue 14. The number discs may be provided with projections to enable them to be set in the dark. In a modification, Fig. 6, each spindle 5 carries, in addition to its tumbler 1, a supplementary tumbler 1b. A pin 16 on the tumbler 1 engages an arcuate slot in the tumbler 1b. To set the combination to free the bolt, the number disc 4 is turned while the pin 16 is at one end of the slot so as to set the tumbler 1b, and is then turned back so as to set the tumbler 1. In a further modification, the pin 16 moves between two stops arranged on the tumbler 1b and on a bush mounted on the same. The tumbler and its bush are relatively rotatable so that the separation of the stops may be varied.
