Abstract: 1,129,570. Photo-meters. INTERNATIONAL POLAROID CORP. Dec.13, 1966 [Dec.27, 1965], No.55842/66. Heading G1P. [Also in Division G2] Photo-metric apparatus for examining the brightness of a field of view and which may be used in or with a camera contains a means for selecting a photo-metric value and an illuminated indicator system containing light sources which are illuminated when activated, said system providing one illuminated visual signal when the selected value is less than that of the brightness of the field of view, another positive signal when the values correspond. Light from the field viewed enters via aperture 42, passes through variable density filter 46 and strikes photo-conductor 30. Depending on the light received by the photoconductor and the setting of potentiometer 32 which is adjusted according to the film speed used, either lamp 20 or 22 is illuminated indicating through masks 60 and 62 that the setting of the variable filter 46 on scale 48 requires correction. When the setting is correct both lamps light. The apparatus may be coupled to a camera diaphragm via rack 52 and pinion 54 as shown, or alternatively to a camera shutter or to a shutter and a diaphragm. The disc filter 46 may be replaced by a linearly movable filter or optical wedge or a diaphragm, or may be dispensed with altogether in which case the potentiometer 32 is varied to control the apportionment of voltage to lamps 20 and 22. In a further alternative arrangement a second photo-conductive cell replaces the potentiometer 32 and a filter arrangement admits light from the field of view to both photo-conductive elements in inversely varying quantities.

Title: Synchronizing signal separator
IPC: H04N5/213
Filed: 1969-11-14
Abstract: 1284586 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Nov 1969 [19 Nov 1968] 55850/69 Heading H4F In a sync separator employing a self-biasing limiter utilizing an RC circuit the limiter is disabled by a series connected switch and means are provided to maintain the charge on the capacitor substantially constant during the occurrence of interference. As shown, Fig. 1, the input video signal 17 is applied via an emitter follower 1 to the emitter of a limiter transistor 9 the base of which is biased by an RC network 13, 14, 12 so that transistor 9 bottoms during the sync pulses which appear as negative going signals 20 at the collector terminal 11. Interference pulses in the incoming signal are selected, for example by filtering out 3 MHz components and low frequency components having an amplitude greater than the sync pulses, and applied as a signal 18 to a switching transistor 3 connected in series with the limiter 9. Transistor 3 is normally bottomed but when a noise pulse occurs it is cut off thus disabling limiter 9. A second transistor switch 14 is connected in series with resistor 13 and this switch is also cut off during noise pulses to prevent the charge on capacitor 12 from varying. Capacitor 12 may be connected in parallel with resistor 13 and transistor 14 instead of in series as shown. In a modification, Fig. 2 (not shown), the second switch is arranged so that when a noise pulse occurs the capacitor (12) is clamped to a voltage associated with the nominal amplitude of the video signal. This enables all the transistors used to be of the NPN type and the circuit may therefore be produced in integrated form. The circuit may also be arranged to utilize a valve having several control grids, for example a hexode, in which case negative going interference pulses are applied to the first control grid and positive going video signals are applied to a second control grid through a capacitor this grid being connected to a positive voltage or to earth via a leakage resistor formed as a potential divider, the tapping point of which is connected via an isolating capacitor to the first control grid to reduce the leakage from the first mentioned capacitor during interference pulses.

Filed: 1971-12-16
Abstract: 1345950 Digital computers; time sharing INTERNATIONAL STANDARD ELECTRIC CORP 16 Dec 1971 [22 Dec 1970] 58428/71 Heading G4A In a time sharing digital electric data processing system tasks are organized into queues for execution. A number of remote terminals 10 communicate with a time shared computer 11. A scheduling unit 16 (which may form part of unit 12 or 13) schedules tasks which are solely interrupt driven and those generated by a terminal user. Some of the tasks have predictable durations while others are unpredictable. Other tasks require a resource allocation and their duration depends on the availability of the resource. Scheduling is controlled by unit 16 using programmed timer interrupts. In this embodiment there are 18 queues, P1-P18, having different priorities, each queue containing descriptions of the tasks therein and each queue being arranged on a first in first out basis. The first three queues have highest priority and their tasks are executed in sequence, all the P1 tasks being executed first. The tasks in P1-P3 are urgent tasks with a short predictable duration and all of these are executed before queues P4-P18 are dealt with. Queues P4-P16 are of unpredictable duration and the level of queue for normal cases depends upon the amount of CPU time accumulated. Jobs start at P4 and, as they are given increments of CPU time, they are stepped down to lower queues. Each queue level contains a specific quantity of CPU time (a quantum) which increases as the queue level increases. The size of the quantum depends on the swapping media used, e.g. drum or disc. Scanning means determine whether a task is to continue being executed or another task is to replace it, depending on the time available. Queues P17  and P18 are for internal user queues and are serviced in a similar manner to queues P4-P16. A complete scheduling programme is also described with reference to Fig. 4 (not shown).

Abstract: 1410197 Hydrostatic transmission control; valves CATERPILLAR TRACTOR CO 20 Dec 1972 [27 Dec 1971] 58858/72 Headings F2W and F2V In a hydrostatic transmission for a tracked vehicle wherein each track is driven by a separate hydrostatic transmission having a pump 28 or 29 supplying pressure liquid to a motor 16 or 17 through a combined flow control and reversing valve 24 or 25, the flow control and reversing valves 24, 25 are simultaneously adjusted equally in response to actuation of a first pilot valve 35 or 36 for forward or reverse drive and are selectively adjusted in response to actuation of second pilot valves 40, 41 to effect differential ratios in the transmissions for steering purposes. A pump 30 supplies liquid at a pressure determined by a relief valve 32 to the first pilot valves 35, 36. For forward drive the valve 35 is depressed to meter liquid through ducts 42, 47; 44, 49 to the flow control valves 24, 25 which are thus adjusted equally to provide equal motor output speeds. The output speeds of the motors 16, 17 is responsive to the depression of the valve 35. For reverse drive the valve 36 is depressed to meter liquid to the opposite ends of the flow control valves 24, 25 which are thus moved in the opposite direction to condition the motors 16, 17 for reverse drive. To steer the vehicle a lever 106 selectively actuates the valve 40 or 41. Initial movement of the valve 40 (or 41) meters pressure liquid to the opposite end of the flow control valve 24 (or 25) to slow the associated motor 16 (or 17). On further movement of the valve 40 (or 41) the pressure to the opposite end of the flow control valve 24 (or 25) is increased to further slow, stop or reverse the associated motor 16 (or 17). On completion of the steering manoeuvre the valves 40, 41 are spring pressed to their normal positions and the hydrostatic transmissions are returned to providing equal output speeds. Each pilot valve 35, 36 comprises a valve spool 66 having a number of metering slots 72 which selectively connect an outlet duct 43 to a pressure liquid supply 30 or a vent duct 77. The valve spool 66 is urged by a spring 67 to the position shown in which the outlet duct 43 is connected to exhaust 77. Depression of a pedal 86 acts through a plunger 61 and spring 62 to depress the valve spool 66 and thus connect the outlet duct 43 with the supply pump 30.
