Title: Improvements in visual monitoring devices for cinematograph cameras combined with or operating with sound recording systems and apparatus
IPC: G11B7/00
Filed: 1936-07-28
Abstract: 463,601. Kinematographs and associated sound-recording apparatus. KOLB, O. K. July 28, 1936, No. 20841. [Class 40 (ii)] A visual monitoring device for a kinematograph associated with a sound-recording system is constructed so that a single operator can supervise the functioning both of the kinematograph and the sound-recording apparatus simultaneously through one viewing aperture, or by bringing indicia relating to the several operations simultaneously into one field of view. A light beam modulated by an oscillograph O, Fig. 1, may be divided by a glass plate R so that a direct beam proceeds through the mask M and an optical system to a combined picture and sound recording film F, a reflected beam passing through a second mask MI to a mirror R2 in the kinematograph camera view finder V. A footage indicator for the film may also appear in the field of view. The image of the sound recording slit may appear below the image of the view instead of being superposed thereon. In a modification, a reflecting sytem is arranged to give a direct image of the mask M in the camera viewfinder. A spot or linear beam of light may be reflected from the oscillograph so as to vibrate over a scale in the camera view finder. When recording is effected by the variable-density method, a light beam of sound modulated intensity is divided and reflected substantially in the manner previously described with reference to Fig. 1, in order to give a stationary image of variable intensity in the view finder. In a further modification, in which a camera separated from the soundrecording system is employed, the soundrecording oscillograph OS, Fig. 10, may project a linear beam on to a fixed graduated mirror M from which the moving image is reflected into the camera view finder. Other data, such as that furnished by an exposure meter, may also be indicated in the view finder. The view finder may have a plano-convex object lens with cross lines or other indicia on the plane face, which is preferably disposed outwardly.

Title: Spraying equipment
IPC: A01M7/00
Filed: 1975-05-16
Abstract: 1507149 Measuring liquid spray rate E ALLMAN & CO Ltd and L I A TAYLOR  14 May 1976 [16 May 1975] 21028/75 Heading G1N. The rate at which liquid is applied to a ground area by spraying is indicated by the quotient of a first signal corresponding to the rate of flow of liquid to spraying nozzles and a second signal corresponding the speed of traverse of the equipment over the ground. As shown Fig.1, a tractor carrying liquid in a tank 7 for spraying from a boom 1, incorporates a flowmeter 9, measuring the rate of flow of liquid to the boom, and a tachogenerator 11 mounted on a jockey wheel 13, for measuring the speed of the tractor. Both measuring signals are in the form of pulse trains having a frequency proportional to the measured quantity. The speed signal is fed through a pulse shaper 19 Fig. 2 to a monostable multi-vibrator 23: the flow signal is fed through a pulse shaper 21 to an amplifier OA4 which steps up the voltage across a feedback capacitor C4 with each flow signal pulse, until reset by a pulse from monostable 23. The output voltage from amplifier OA4 is therefore proportional to the flow signal divided by the speed signal. This is amplified and smoothed at T1, T2 and shown at meter 27 as litres per hectare, the scale being adjusted by variable resistor S1. The liquid from tank 7 is drawn of by a pump 5. Excess liquid is fed back via valve 29 and switch 31 winch energizes a warning lamp 33 when the return flow is too small. Counters may be added to measure the total liquid flow and the total area covered.

Title: New or improved means for controlling undesired movement of a vehicle
IPC: B60T7/12
Filed: 1938-07-18
Abstract: 518,168. Preventing reverse movement of vehicle and other shafts. HACKETT, , A. G., and EDWARDS, J. L. July 18, 1938, No. 21210. [Class 103 (i)] [Also in Group XXIV] For ensuring unidirectional rotation of the shaft of a vehicle, crane &c., part-circular detents 12 are mounted to turn in recesses ina fixed member 10, to engage a toothed disc 11 on the shaft. The tooth faces engaged by the detents are preferably concentric with the detents to facilitate disengagement when required. As applied to the end of the wormshaft 27 of a vehicle rear-axle drive to prevent reverse movement of the vehicle, detents 29 mounted in a fixed casing 28 to engage a toothed disc 25 on the shaft are held in neutral position during forward running of the shaft by a cam ring 33 frictionally engaged with the shaft, the periphery of which engages parts 30 of the detents. Turning movement of the ring 33 is. limited by a stop 38<1>. When the shaft tends to reverse, recesses 37 in the ring 33 permit springs 32 to turn the detents into the engaged position. The cam ring may be held in neutral position, to permit reverse movement of vehicle, by engagement of a lug 40 on the ring with a finger 41 on a spindle having an arm 43 which may be connected to a hand- 'lever or to the, gear-selecting mechanism. According to Fig. 11, a vertical hand-lever l controlling the detent device is mounted adjacent the gate of the change-speed mechanism and normally occupies the position 601. When the gear lever is moved in the slot shown to the reverse position R it engages a peg 63 on lever l and moves this lever to position 60<11> in which the detent is held out of action and in which it is held by a latch 65 until when the gear lever is moved to the other end of the slot to engage a forward gear, it engages a finger 67 which releases the latch and permits return of the lever l. In another arrangement a lever mounted on the gear box is adapted to be moved to hold the detent out of action by the selector rod which engages the reverse gear and to be held in this position by a latch which is disengaged by the selector rods for engaging the forward gears. The detents may instead be controlled directly by a hand-lever or in the case of a trailer vehicle by breakage of the coupling, by a spring-urged cam ring' which puts the detents into engagement when a latch is withdrawn by a cable extending to the tractor.
