Title: Improvements in colour photographic printing
IPC: G03C7/18
Filed: 1943-02-03
Abstract: 581,927. Reproducing colour photographs using polarized light. KODAK, Ltd. (Eastman Kodak Co., Hanson, W. T., and Evans, R. M.). Feb. 3, 1943, No. 1787. Drawings to Specification. [Classes 97 (i) and 98 (ii)] In printing a multi-coloured original on to a light sensitive material with a single beam of light the colour balance is controlled by passing the printing light through two uniform polarizing devices, one of which is an ordinary polarizing filter and the other is either a monochromatic vectodye filter (comprising a sheet of transparent material, e.g. cellulose ester, having embedded therein oriented crystals or molecules of a dye such that the light passing therethrough is polarized in two directions at right angles, the absorption of such polarized light being negligible in one such direction and confined to some limited band of the spectrum in the other direction), or is a birefringent. layer in combination with a second ordinary polarizing filter whose vibration axis is oriented somewhere between the two vibration axes of the birefringent layer, the birefringent layer being between the two ordinary polarizing filters. With the first type, a rotation of 180 degrees is required to change from neutral to maximum saturation and back to neutral ; with the second type, a rotation of 90 degrees is required, and a further rotation of 90 degrees carries the colour through maximum saturation of the complementary hue again to neutral. The birefringent layer may be arranged with its vibration axes at substantially 45 degrees to the axis of the ordinary polarizing filter. Additional colour filters may be included in the optical system. The light may pass through the two filters in either order and filters may be anywhere between the light source and the sensitive surface. Where a vectograph image is used as a colour correction mask as in Specification 581,926, the polarizing filter may be first. adjusted relative to the vectograph mask to give the degree of masking required and the variable saturation colour filter adjusted relative to the polarizing filter to give the saturation required to correct the colour balance of the original and its mask relative to the sensitivity of the light sensitive printing material. The polarizer should be between the mask and the variable saturation colour filter. The birefringent material may be " Cellophane " (Registered Trade- Mark) or mica. Two or more variable saturation filters may be used in series, if necessary with an intervening depolarizer, e.g. a ground glass screen on which the image from the first system is focused. Specification 499,797 also is referred to.

Patent GB-758846-A (GB)
Title: Improvements in or relating to digital servos
Inventor: SEID EUGENE
IPC: H03M1/00
Filed: 1954-01-22
Abstract: 758,846. Electric selective signalling. NORTH AMERICAN AVIATION, Inc. Jan. 22, 1954, No. 2019/54. Class 40(1) [Also in Group XL(b)] The invention relates to a servo-system as disclosed in U.S.A. Specification 2,537,427 in which a servomotor shaft is rotated in accordance with the magnitude and sign of a digital number. Incoming signal impulses, positive or negative, are fed over a synchronizer 15, Fig. 1, to a reversible binary counter A, the count in which is converted by denominational summing resistors 36-44 into an analogue voltage at point 45. This voltage is amplified at 7 and operates a reversible servo-. motor 1 which drives a disc 9 co-operating with photocells 10, 11 to generate pulses corresponding in sign and number to the sense and magnitude of the servomotor displacement. These pulses are fed over synchronizers 13, 14 to the counter A and subtracted from the reading therein until the count reaches zero, where the servomotor displacement corresponds to the count of the incoming signal pulses. The synchronizers prevent inaccurate operation of the counter by simultaneously received pulses. According to the invention the servomotor is driven linearly, i.e. proportionally to the count, only for relatively small positive numbers registered on the counter, e.g. between zero and 2<SP>8</SP>. When the count exceeds these positive values or goes negative, a constant voltage of sign corresponding to that of the number is fed to the amplifier by relays 62 or 64 to override the summing voltage at point 45 and drive the motor-at maximum speed until zero. is reached in the case of negative impulses, or, for a positive, number until the count is reduced below 2<SP>8</SP> when proportional control is restored. To this end the higher denominations 25-35 of the counter are connected to diodes 59...51, 48, 60. Since the counter may register positive or negative numbers zero is chosen as that condition in which denominational element 24 and 35 are "on." Should the number registered be positive and exceed +2<SP>8</SP> one or more of the diodes 59...51 corresponding to the "on" counter elements 25... conducts and blocks the diode 49 whereby the triode 47 is energized and operates the relay 64. Should a negative number of any magnitude be registered, diode 60 conducts to unblock triode 61 and actuate the relay 63. At same time diode 48 conducts to block triode 47 and release relay 64. In either case the servomotor is driven at maximum speed until proportional control is restored at 2<SP>8</SP> for positive numbers and until zero is reached in the case of negative numbers. In a modification (Fig. 4, not shown) the section A of the counter and therefore proportional control is dispensed with, the servomotor always being driven at maximum speed in the appropriate sense until the number in the counter has been counted down

Filed: 1934-01-20
Abstract: 432,112. Taximeters. FISHBURN, J. E., 39, St. James's Street, Westminster, and WEBB, C. F., 33, Kenton Park Avenue, Kenton Park, Middlesex. Jan. 20, 1934, No. 2054. [Class 106 (iii)] To permit the fare indicator of' a taximeter to be rotated through an angle so as to be readily visible to a person standing by the side of the taxicab, the casing 1 housing the clock and gear mechanism has upper and lower cylindrical bosses 2, 3 mounted in bearings 4, 5 in the horizontal limbs 7, 8 of a bracket 6, the extent of the rotational movement being limited by a pin 9 working in a curved slot 10. When the driver displaces the flag 14 through 180 degrees to the " hired " position, a cam 18 on the flag spindle 16 is simultaneously rotated, and on a further rotation through 90 degrees to the " clock stopped" position the cam 18 lifts a lever 20 so that it engages a pin 25 and displaces a lever 24 to move a locking-pin 26 out of a recess and so releases the casing 1, whereupon it can be swung about a vertical axis for the purpose described. Finally the driver or a spring restores the casing 1 to its normal position, the last movement of the flag, restoring the levers and the locking-pin to the positions shown in Fig. 1. The invention may be used in conjunction with the inventions described in Specifications 427,577 and 432,111.

Title: Elevator-system controls
IPC: B66B1/14
Filed: 1968-01-15
Abstract: 1,208,623. Lift control systems. RELIANCE ELECTRIC & ENG. CO. 15 Jan., 1968 [20 Jan., 1967], No. 2067/68. Heading B8L. A lift control system includes means for ascertaining the actual distance which the or each car must travel to answer a given hall call. The arrangement consists of logic circuit elements and comprises a scanner (common to all cars) which interrogates each floor in turn, and a gating circuit for each car which gates pulses from the scanner to a counter (one for each car) only when the scanner is interrogating a landing which will be passed by that car (in either direction). The gating circuit effectively determines the limits between which its car will travel in answering the call, having regard to (a) the location of the car, (b) registered car calls, (c) previously allotted hall calls and (d) the hall call which is to be allotted. The invention is preferably applied to the multicar system described in Specification 1,163,728, in which hall calls are allotted to whichever car is best able to provide service having regard to its work load and position. In that system a car travelling away from a hall call was assumed to be travelling to a terminal floor, but with the present invention the point of reversal is determined and so only floors actually to be traversed are counted.
