Title: Apparatus for detecting changes in optical density in a moving web
IPC: G01N33/34
Filed: 1971-10-11
Abstract: 1385689 Detecting edges photo-electrically BOWATERS UNITED KINGDOM PAPER CO 11 Oct 1972 [11 Oct 1971] 47209/71 Heading G1A An edge of a moving sheet material e.g. an edge at a splice between two webs or at a void or hole in the material, is detected photo-electrically. As shown, the web S passes between a daylight type miniature fluorescent tube 3, emmitting predominantly blue or ultraviolet light, and a blue or ultraviolet-sensitive photo-cell 2, since the splicing tape used to join webs has strong absorption of this colour, and effectively cuts off transmission of light to the photo-cell. The source is modulated by a transistorized supply, to produce a 16KHz flicker frequency. The detecter circuit comprises an impedance buffer amplifier 4, potentiometer and logarithmic amplifier 19. The channels of differential amplifier 5 include operational amplifier 6, which has a bandwidth of 1H 2  and responds slowly in accordance with changes in web density, but not to rapid changes such as at an edge, and amplifier 7, having a 10 KHz bandwidth, and responding to rapid changes. The two output channels feeding indicators 16, 16a are respectively for indicating splices and voids (high and low absorption levels).

Abstract: 1444993 Selective signalling NISSAN MOTOR CO Ltd 12 Oct 1973 [14 Oct 1972] 47835/73 Heading G4H In apparatus to prevent drunken driving, two sequences of characters are displayed in turn and means are provided to detect whether a push-button was actuated at each character in the second sequence which also occurred in the first sequence. As disclosed, a ring counter has 9 stages to control display of the digits 1--9 respectively, the counter being driven at a high speed and stopped four times to display four digits in a first phase, circuit tolerances and the high speed ensuring that the digits are a random sequence except that each digit displayed causes a respective control flip-flop to be set to cause bypassing of the respective stage of the ring counter in subsequent cycling so that the four digits are all different. In a second phase, the counter is cycled through all its stages once so that the digits 1-9 are displayed in turn, and as the driver sees a digit displayed which he remembers was displayed in the first phase, be actuates the push-button which reverses the state of the control flip-flop corresponding to the current stage of the ring counter. At the end of the second phase, an AND gate detects whether all the control flip-flops are reset. If so, supply of power to the vehicle electrical circuits is permitted. Alternatively, an alarm is given if not.

Abstract: 1,073,875. Positioning magnetic head assemblies; electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 17, 1965 [Dec. 16, 1964], No. 48777/65. Headings G4H and G5R. [Also in Division H3] A magnetic head assembly (22, Fig. 1, not shown) is positioned radially on one of 512 tracks on a magnetic disc (10) by comparing the number of the desired track with the number of the actual track and using the error signal to correct the position. The disc may include a clock track (14) operating on a count base of 512 and feeding a binary counter (44, Fig. 2, not shown). A first digital quantity representing the desired track is stored in a register (40), and a second digital quantity representing the actual track is stored in a second register (42), the two registers feeding respective comparators (46 and 47) which produce output pulses each time the binary counter (44) reaches the corresponding digits. The output pulses are used to start and stop ramp generators which produce an output which is proportional to the magnitude and sense of the error and which is used to control a transducer positioning mechanism. The transducer mechanism may include a reference pattern sensor of magnetic or optical type for indicating the. actual track, or the reference track (14) may include radial variations by which the separate data track positions may be identified. The disc (10) may be one of a number of parallel discs in a multi-disc array mounted on a common shaft.

[Also in Division F2] A pneumatically or vacuum operated friction clutch in the drive of a fan of an engine cooling system is controlled by a thermally responsive device. As shown, a compressed air operated clutch has an axially movable output member 26 connected by a universal joint comprising rubber rings 34-36 to a fan disc 25. Clutch engagement is assisted by the axial reaction thrust of the fan. The clutch member 26 carries an internally cored split friction ring 40 which is engagable with an externally cored lip 52 of an axially fixed driving clutch part 50. Clutch parts 26, 50 are formed with axial extensions 27, 53 forming respectively an axially movable cylinder and a stationary hollow ram, the cylinder 27 being rotatably mounted on the ram 53 by roller bearings 54, 55. A release spring 57 acts through a pin 59 and bearing 55 to bias the clutch member 26 to its disengaged position, the clutch being engaged by compressed air admitted to the interior of the ram 53 under the control of a valve which is controlled in accordance with the air temperature, or coolant temperature or engine block temperature. The air pressure acts on an end wall 68 of the cylinder, and is also admitted, through ports 75 to a chamber 76 to urge a sealing member 78 into sealing engagement with the clutch member 26. Air is admitted to the ram by way of a line 19 and a spigot 65 which is supported in an extension 67 of the cylinder end wall 68 by an oil impregnated bushing 66. Details of a vacuum-operated clutch are shown in Fig. 3 (not shown).

Abstract: 1,214,047. Milking machines. RESEARCH CORP. 17 Oct., 1968, No. 49199/68. Heading A1M. [Also in Divisions B8 and F2] A pneumatic milking machine comprises valve means 16, 34 for alternately connecting inflation assemblies 22 to a milk line 10 or to a sanitizing line 28. The valve means 16, 34 comprise three spigot valves interconnected to be rotated simultaneously by a handle 62 to connect the milk line 10, or the sanitizing line 28 via a connecting tube 57, to the inflations 22. A fluid measuring device 32 includes a flexible diaphragm 82 provided with a metering orifice 88. On opening the spigot valve 54 sanitizing fluid from a lower chamber 92 is discharged; the diaphragm 82 is depressed by fluid from a pressurized container 26 entering an inlet 30 until the orifice 88 is engaged by a needle valve member 100 raised by a cam track 76, Fig. 5 (not shown), on a plug member 58 of the spigot valve 54; the orifice 88 is too small to allow significant flow into the chamber 92 during discharge. On turning the handle 62 to the milking position, the member 100 retracts, liquid from an upper chamber 90 being gradually transferred to the lower chamber 92 as a spring 94 raises the diaphragm. To avoid mixing of milk and sanitizing fluid each nipple 20 of a claw e.g. 12a is sealed by the interior wall of a milk tube 24 which hangs down during sanitizing, Fig. 3 (not shown), a sanitizing fluid conduit (42) being similarly sealed off when the milk tube 24 is upwardly disposed during milking, Fig. 2 (not shown).
