Title: Photocomposing Apparatus.
IPC: B41B17/34
Filed: 1967-12-05
Abstract: 1,165,629. Photographic type-composing. FAIRCHILD CAMERA & INSTRUMENT CORP. 5 Dec., 1967 [29 Dec., 1966 (2)], No. 55353/67. Heading B6W. A photographic type-composing machine comprises a character drum 15, Fig. 1, comprising a disc 23, Figs. 2 and 6, having positionrepresentative slits 17 sensed by a photo-cell 19, and two font rings 22, 23, each comprising eight segments mounted on eight drum segments 37a-37A. Each ring, such as 22, Fig. 5, is provided with transparent characters 24 in groups of eight differing in size and style and defining eight peripheral tracks, the groups being aligned with slots 37i in the drum segments, and the tracks consisting of sets of six interlaced characters passing through a projection zone 31c of an optical system. The rings also contain, for each group of characters, character-representative code holes 25, a character-ready hole 25a and a position-representative slit 26. A mask 36 is mounted inside the drum segments, and is provided with slots 36a aligned with one of the six groups in a set, slots 36b aligned with the corresponding marks 25, 25a, 26, and shorter slots 36c 36d for short lines. There are two series of each type of slot, one for each ring, the mask being circumferentially adjustable to one of six positions by a stepping motor 41 through a cam 42. The intersection of a slot 36a or 36c and the zone 31c defines one character which scans a photosensitive film 10, movable only for line spacing, as the character passes through the zone. A first optical system comprises a lamp 30 and lens assemblies 31, 31a, 32, 31b mounted on a carriage 58 for adjustment axially to the desired one of the eight tracks by means of a motor 56 through a cam 57. A second optical system comprises a light source 59 and lens assemblies 60, 61, 62, 62a, which projects light through the masks 25, 25a, 26 to a photodiode array 63, the assemblies and source being mounted on a carriage 65, which also supports the carriage 58, movable to select the font ring by mechanism 67. A computer 12 receives information from the input tape 14 and from the devices 19, 63, and controls the film feed, the mechanism 67 and motor 41, and causes momentary illumination of the lamp 30 when a character is scanning a point on the film where it is to be projected, the arrangement being such that one character is dealt with at a time, being projected on every required position of the line before the next character is dealt with. The computer also controls the flash to give a justified line, according to information as to the number of word spaces and the character widths. The computer is illustrated in detail in Figs. 7a- 7g (not shown).

Title: Analog-to-Digital Code Converter
Inventor: SCHUMAN RALPH HENRY
IPC: H03M1/00
Filed: 1967-04-14
Abstract: 1,190,846. Shaft encoders. WARNER & SWASEY CO. 14 April, 1967 [6 June, 1966], No. 61787/69. Divided out of 1,190,845. Heading G4H. The description is identical to that of the Specification 1,190,845 but the invention claimed is a shaft encoder comprising a coded disc. Fig. 4, of which tracks 1, 2 and 3 are sensed by a plurality of slits through which light passes to cause photo-cells to provide signals from which an indication is derived of the shaft angle, the track 3 and the co-operating phase-displaced slits F+ and G+ giving precisely defined signals and the tracks 1 and 2 and the co-operating phase-displaced slits A+ to E + providing a number of imprecisely defined signals which have a larger tolerance than the precisely defined signals and which, in logical dependence on the precisely defined signals, define a cyclically coded value for the shaft angle. The signals A-G for 20 steps are shown in Fig. 5. They are combined in a decoder circuit which is such that only signals F and G need be accurate. For example the beginning (or end) of signal A could occur anywhere in the space corresponding to steps 8 and 9. For sensing the track 3 there may be groups of three photo-cells reading equivalent parts of adjacent scale markings. All the slits may be complemented by antiphase slits A - to G - which are combined in push-pull fashion to improve the switching operation of the decoding circuitry. The direction of movement is indicated by the order of occurrence of the F and G signals. Tracks 4-7 defining the decimal digit of the next decade are each sensed by lead and lag slits 20d, 20g; 40d, 40g; 80d, 80g; 100d, 100g. The lead or lag signal is selected in dependence upon the signals A-G, an output from the decoding circuit serving to open appropriate gates.

Title: Devices for Controlling the Merging of Two Streams of Conveyed Articles
IPC: B65G47/68
Filed: 1979-02-06
Abstract: A device (10) for controlling flow of articles travelling along first and second lanes (5, 6) which converge to a third lane (7) so that articles from both the first and second lanes do not simultaneously pass through the region of convergence of the first and second lanes, comprising; first means (pivoted cam plate 11 and stop arm 12) for association with the first lane, and having a free or rest state and a locked state, the first means when its locked state being adapted to prevent release of articles from the first lane to the third lane and when in its free state being adapted to sense and be actuated by articles travelling along the first lane; and second means (pivoted cam plate 11' and stop arm 12') for association with the second lane, and having a free or rest state and a locked state, the second means when in its locked state being adapted to prevent release of articles from the second lane to the third lane and when in its free state being adapted to sense and be actuated by articles travelling along the second lane. Actuation of either of the first and second means causes the other means to be put into its locked state. When only one of the first and second means senses an article, that means is actuated to put the other means into its locked state and when both of the first and second means sense articles only the second means is actuated whereby only articles travelling along the first lane are prevented from being released to the third lane. This is accomplished in the embodiment by pivoting the cam plate 11 on the free end of a pair of radius links 15 which can swing about the axis of the pivot of the other cam plate 11', the arrangement being controlled by springs 18, 18' swinging of links 15 resulting in roller 20' being caused to enter recess 21 of the cam plate 11 under such conditions, whereby articles from both the first and second lanes cannot meet at the region of convergence and cause a jam or otherwise interfere with the flow of articles along the third lane away from the region of convergence. <IMAGE>

Title: Improvements in or relating to space diversity receiving systems
IPC: H04B7/08
Filed: 1979-04-30
Abstract: A space diversity receiving system comprises two vertically spaced antennae 10, 11. Signals from the antennae 10, 11 are fed to a receiver 16 via a phase modulator 12 and a phase changer 15. A feedback loop 20 extends from the receiver 16 to the phase changer 15. If the phase relationship of the signals from the two antennae changes from a predetermined value an error signal is produced at the receiver 16 and is fed via the feedback loop to the phase changer. The phase changer operates to maintain the two signals in a fixed phase relationship. A relatively high modulating signal is used for the phase modulator so that the frequency of the error signal is well above the response time of the circuits in the feedback loop 20. <IMAGE>
