Patent GB-1379920-A (GB)
Title: Time resolved spectrometers
IPC: G01J3/28
Filed: 1971-12-23
Abstract: 1379920 Spectrometer with progressive shutter WESTERN ELECTRIC CO Inc 23 Dec 1971 [24 Dec 1970] 59887/71 Heading G1A In an apparatus employing a spectrometer 12, the actual point in time at which absorption or emission of radiation by a sample 21, being irradiated by a source 20, is resolved by including a shutter 24 between the sample 21 and the spectrometer 25, the shutter 24 being activated by shutter operating means such that there is a time dependent spatial displacement of the radiation from the sample which is passed by the shutter. In one embodiment, Fig. 1, the shutter is in the form of a Kerr cell 9B between crossed polarizers 9A, 9C. Light from a laser beam source is split up by a beam splitter 3, as shown, into an exciting beam irradiating the sample 6 and a "shutter" beam 8. This embodiment is designed to cope with and distinguish events which are pico seconds apart, that is, on a time scale of the same order that it takes for a pulse of light from beam 8 to travel down through the Kerr cell 9B. Thus as a pulse of light travels down through the Kerr cell progressive portions of the Kerr cell are caused to rotate their polarization plane in step with the pulse, and so a relatively small travelling portion of the shutter 9 is transmissive at any instant. The time dependent spatially displaced beam containing absorption and/or emission in formation of the sample is received by the spectrometer 12 which may utilize photo-multipliers or spectroscopic plates. The apparatus may also include light valves 13 and 14, (comprising electro-optic or magneto-optic elements in combination with one or more polarizing elements) and cut off filters 15 and 16 in order to regulate the pulses of light irradiating the sample and the shutter. Two examples utilizing a Kerr cell are described one in which the laser beam is split into an exciting and a shutter beam on the basis of frequency with the fundamental frequency being utilized to actuate the shutter while the second harmonic is being utilized to illuminate the sample. The Kerr cell may be replaced by other electrooptic shutters such as those operating on the "Pockets effect", by acousto-optic deflectors utilizing travelling elastic pulses.

Patent GB-690188-A (GB)
Abstract: 690,188. Zeroizing-mechanism. AKTIEBOLAGET ATVIDABERG-FACIT. Oct. 18, 1950 (Nov. 4, 1949], No. 25386/50. Class 106 (i). A clearing device in electrically driven calculating machines of the cam-disc and pinwheel type with product and/or quotient registers, the numeral wheels of which are mounted on a common shaft and the clearing is effected by rotating said numeral wheel shaft one revolution is characterized in that a clearing or zeroizing key, when depressed, releases a lever which thereby is swung by a spring so as to rest, directly or through a roller against a cam driven by the electric motor of the machine, whereafter said lever is forced back to its initial position by the cam and thereby actuates a clearing segment which performs the clearing operation. The zeroizing key 19, Fig. 1, is depressed whereupon a pivoted lever 4 and a segment 9 to which it is attached by a link 7 are moved clockwise by a spring 21 until the roller 5 on the lever 4 abuts a cam 2 on a shaft 1. The key 19 closes contacts 28, whereupon the electric motor rotates the shaft 1. A locking lever 24 is moved by a spring 26 to engage the top of the key 19 and keep it depressed. In the above movement the segment 9 has swept idly past a pinion 15 on the shaft 16 of the register, this being made possible by providing a cut-away recess 15a in said pinion. The cam 2 now moves the lever 4 and therefore the segment 9 anticlockwise. A pawl 11 pivoted to the segment 9 engages the pinion 15 and moves it one tooth so that the segment 9 may then drivingly engage and rotate the pinion 15 and the shaft 16 one revolution. The shaft 16 is moved axially by a pin and cam arrangement, Fig. 2 (not shown), so that. the numeral wheels may be zeroized. When the lever 4 is back at its initial position a pin 27 on the cam 2 returns the lever 24 to its initial position and the key 19 is pulled by a spring 22 back to its initial position in which it locks the lever 4 by the inter-engagement of the projections 19a and 4a. Specification 351,276 is referred to.

Patent GB-2013382-A (GB)
Title: Document sorter utilizing cascaded sorting steps
IPC: G06Q30/02
Filed: 1978-12-21
Abstract: An automatic document sorter particularly suitable for sorting retail store coupons employs a plurality of relatively coarse sorting processes in cascade. The sorting processes sequentially sort the documents according to predetermined properties of the document, including codes, such as bar codes or the like; physical properties, such as size, thickness, colour, reflectivity and opacity; the characteristics of the inscriptions on the face of the document; and any uniquely marked areas of the document face. Such a sorting hierarchy permits the documents to be sorted rapidly by reducing the precision required in each sorting step. The hierarchy also permits each document to be classified during each sorting step as falling into a particular class of documents in order to simplify subsequent sorting steps. If a property uniquely identifying the document is found during any one of the sorting steps, the processing is terminated at that point without completing the subsequent sorting steps.
