Abstract: 1,185,910. Optical filters; holograms. BRITISH AIRCRAFT CORP. Ltd. Dec.23, 1968 [Dec.21, 1967], No.58192/67. Heading G2J. An optical filter having the transmission characteristics of a pattern embossed on the surface of an object (e.g. a fingerprint) is recorded by pressing the object 2 against one side 3 of a partially reflective surface of a rigid transparent medium e.g. glass 1, illuminating the surface by a source of coherent light a, b, collecting the light waves a<SP>1</SP>, b<SP>1</SP>, reflected from the opposite side of the surface 3 against which the object is pressed by a lens 5 which converges the waves on to a photographic plate 6 located in the focal plane of lens 5. The troughs and ridges of the pattern pressed against the surface produce a characteristic variation in the refractive index over the surface and the resulting phase and amplitude variation of waves a<SP>1</SP>, b<SP>1</SP> are recorded on plate 6. In this embodiment the plate 6 records the Fourier transform of the fingerprint XX<SP>1</SP>. To avoid interference between waves reflected from the front surface 4 of medium 1 are those carrying the desired information either the medium must have a suitable thickness or the object surface 3 may be suitably angled. Alternatively a right angle prism may be used with three internal reflections produced. In a further embodiment the source of coherent light may be split to give a reference beam which follows an approximately equivalent path length before being superimposed on the rays a<SP>1</SP>, b<SP>1</SP> on plate 6 to form a hologram. The filter is for use in an optically matched filter character recognition system.

Patent GB-700946-A (GB)
Abstract: 700,946. Calculating-apparatus. BURROUGHS ADDING MACHINE CO. Aug. 27, 1951 [Oct. 6, 1950], No. 20135/51. Class 106 (1) A calculating-machine having means for transmitting totals from a first totalizer to a second with suppression of transmission in the lowermost or decimal orders, is characterized by manually-controllable detaining means which hold the decimal order wheels of the first totalizer during resetting following a transmission to the second totalizer, and by yieldable connections in the resetting means for the decimal orders. The suppressed decimal amounts are thus continuously accumulated in the first totalizer for ultimate transfer to its higher orders and thence for transmission to the second totalizer. The invention is shown applied to the machine described in Specifications 450,591 and 484,095. In that machine, amounts set on a key-board are accumulated on a front totalizer comprising pinions 46 and interconnecting transfer mechanism of the " crawl-carry" type as described in Specification 131,109, [Class 106 (1)]. Snail cams 61 of the transfer mechanism, through followers 64, maintain stop members (not shown) differentially positioned according to the amount registered by the front totalizer so that, upon operating a total-transmission key Tr, feelers engage the stop members and advance a rear totalizer by a corresponding amount or its complement. Transmission in the three lowermost or decimal orders is suppressed by operating a decimal cut-out key 140 which positions blocking arms in the paths of the feelers for these orders. Following transmission of a total to the rear totalizer, a clearing shaft 227 is operated, arms 228 on this shaft engaging cam projections 230 (see fourth order in Fig. 1) on the followers 64 forcing them clockwise to zero position and resetting the totalizer. Resetting of the three lowermost pinions 46 is prevented, according to the invention, by engagement therewith of stop fingers 222 pivotally supported on a bail 220 carried by a yoke 217 adapted to rock about a shaft 218. The stop fingers are rendered effective by depressing a key 200 which, through a spring 205 and a lever 206, rocks a pawl 210 clockwise' into engagement with a stud 237 on an arm 226 secured to the clearing shaft 227. The pawl 210 is pivoted to a lever 212 carrying a roller 214 engaging a cam-slot 215 in a side arm of the yoke 217. During forward (counterclockwise) rotation of the clearing shaft 227 following depression of the key Tr, the arm 226 carries the pawl 210 forward and the lever 212 swings the yoke 217 to bring the fingers 222 into holding engagement with the three lower totalizer wheels 46 before the arms 228 are effective to reset them. In these three orders, the arms 228 operate the follower arms 64 through intermediate levers 232 and springs 234 which yield when the fingers 222 are holding the totalizer wheels. The key 200 is adapted to carry the key 140 with it, and so acts as the decimal cut-out key when decimal amounts are to be retained in the front totalizer.

Abstract: 751,957. Counting -apparatus; transfer mechanism. RONEO-NEOPOST, Ltd. Jan. 18, 1954 [Oct. 17, 1952], No. 26062/52. Class 106 (1). A multi - order postal franking machine has two totalizing counters, actuated by mechanism comprising for each order a toothed wheel or drum the number of effective, teeth of which is variable, and having externallyoperated transfer mechanism. The actuators are set by means of spring- loaded plungers 7 having indicating drums 8. The plungers are rotated to drive cams 5 which project an appropriate number of teeth 4 into operative positions. Racks 9 bodily rotatable with the driving shaft 2 are simultaneously moved to set printing dies 12 in a drum 10 on the shaft 2. Adjustable date dies are also carried by the drum 10. The dies are inked by a roller 15 and impressions are taken by a printing head through an aperture 17. The driving shaft 2 is rotated by a motor or hand-crank, a pawl and ratchet preventing reverse rotation. The actuators drive two meters or totalizers, one of which is driven subtractively and is pre-set to a pre-paid amount. Each totalizer comprises driven pinions 21-24 for halfpennies, pennies, shillings and tens-of-shillings orders. Indicating discs 20 are fast with the driven pinions and further discs indicate hundreds and thousands of shillings respectively, these being overflow orders. Transfer mechanism. The halfpennies actuator is arranged to be effective before the other actuators and at every other step of the halfpennies disc 20, one of three transfer fingers 25 fast therewith advances a spur wheel 27 fast with the pennies disc. Also fast with the pennies disc is a finger 30 which at transfer rocks a lever 44 controlled by a toggle spring and pivoted on a slide 45. At the end of a cycle, the slide 45 is moved to the left by a cam 53 on the driving-shaft and a tooth 46 of the lever advances a wheel 31 fast with the shillings disc by one step. The lever 44 is then re-set by a fixed stop 47. Transfer from the shillings order is effected in a similar manner by a lever 48 on a slide 49 actuated after the slide 45. Transfer in the overflow orders is effected directly by fingers 36, 39 engaging wheels 37, 40. For re-setting purposes, the latter transfer mechanism may be disengaged by knobs 42. The spur wheels, e.g. 27, and a wheel 29 on the halfpennies are engaged by detent levers, e.g. 56. The transfer levers 44, 48 may be mounted on a single slide, the lever 44 being arranged to operate on the forward stroke and the lever 48 on the return stroke or they may be replaced by star-wheels. Alternatively, fixed star-wheels may be arranged between denominations, the transfer finger of a lower order conditioning the star-wheel for subsequent further rotation to enter a unit in the higher order. Specification 538,727, [Group XVI], is referred to.
