Patent GB-1371276-A (GB)
Title: Agricultural machine
IPC: A01D41/127
Filed: 1972-09-04
Abstract: 1371276 Automatic control of steering MASCHINENFABRIK FAHR AG 4 Sept 1972 [13 Sept 1971] 40898/72 Heading G3R [Also in Division A1] A harvester is steered automatically by electric means in response to signals from means which sense the edge of the crop. In the embodiment two sensors 12, 13 are arranged as shown ahead of the cutter 28; each covers a zone, a and b respectively, separated by a "dead" zone c Sensor 12 closes a first relay when it detects the absence of the crop and 13 a second relay when it detects the presence of the crop. The absence of such signals indicates that the harvester is on course, in which case its steering is automatically centred, or made to produce a prescribed curve, by an arrangement 14 in which an armature 24 attached to the steering links influences respective coils in series with an A.C. supply and electro-hydraulic valves 16 controlling the steering. Deviation from the crop edge causes energization of the appropriate relay, which disconnects the A.C. supply and energizes the corresponding valve from a battery, thereby effecting steering correction. The sensors may comprise capacitor plates which are deflected by contact with the crop, to vary the frequency of oscillators which operate the relays via respective high and low pass filters, or they may have optical or acoustic transmitters and receivers, the beam being interrupted by the crop.

A metal tube is made by extruding a billet 3 over a mandrel 1 shaped to produce a tube 8 having diminished wall thickness at both ends. The billet is preferably of steel and is first pierced by the mandrel 1 carried by an extrusion ram 4. Oil 7, Fig. 2 (not shown), is then introduced between the mandrel 1 and the pierced bore and the billet is extruded ,between the mandrel and die 6. The extruded tube is subsequently rolled to uniform wall thickness in a stretch reducing mill. A preferred relationship between various dimensions of the mandrel is given.

Abstract: 954,467. Regulating fluid flow. SPERRY RAND CORPORATION. Nov. 5, 1962 [Nov.17, 1961], No.41777/62. Heading G3H. A fluid-flow control device which may be used in a digital data processing system comprises a power fluid nozzle 13 with a helical guide 14 so that fluid issuing from the nozzle into a chamber 12 has a rotary component whereby the action of fluid from a radially disposed control nozzle 15<SP>1</SP> is such as to cause the power fluid to be directed out of the plane containing the axes of the two nozzles so that it enters a receiving nozzle 17<SP>1</SP>. The embodiment shown has eight receiving nozzles to correspond with a similar number of control nozzles. The power fluid when undeflected passes to a waste port 20 situated at the centre of a hemispherical cavity which also receives the fluid stream should its velocity be insufficient to permit of proper deflection by a control nozzle. In a modification, the hemispherical cavity is replaced by a plane surface with the waste port at its centre and each receiving nozzle, of which there may be four corresponding with four control nozzles, consists of a substantially radially elongated port so that the radial position of the power stream in a port, which may be detected by flow sensors, is indicative of the velocity of the corresponding control stream. Alternatively each radial elongated port may be replaced by a row of three separate ports.

Abstract: 921,928. Photographic cameras. INTERNATIONAL POLAROID CORPORATION. July 6, 1959 [July 16, 1958], No. 41785/61. Divided out of 921,921. Class 98 (1). In a photographic camera-as in Fig. 1- adapted for use with a container-as in Fig. 3- holding at least one pair of photographic sheets -as at 16 and 18-in which the sheets of the or each pair are to be withdrawn in superposition from the container through an opening-as at 10-therein by movement of a leader-as at 30 -connected to both sheets, said sheets of the or each pair initially lying in a position in which they are not in superposition (c.f. Fig. 3), the camera has a housing-as at 50-with a space for the container and a predetermined location for said opening, a path extending from this location to an aperture-as at 82-provided in the housing to permit withdrawal of the sheets through the opening along the path and out of the housing through the aperture, and a projection-as at 90-which is resiliently urged into a position adjacent the location and transverse to and intercepting the path and which is deflectable in the direction of movement of the sheets, the projection serving to arrest one sheet of a pair to prevent withdrawal thereof by frictional forces exerted during movement of the other sheet of this pair into superposition with the said one sheet and to release this one sheet by a force of greater magnitude than said frictional forces exerted along the path towards the aperture, so that when both sheets of the pair are urged along by the leader the projection is deflected to permit movement of the two sheets past the projection and out of the camera. Alternatively, said housing and projection may be provided in a film pack holder instead of in a camera. In the embodiment of Fig. 1, said projection comprises one arm 90 of a bell-crank lever pivoted at 92 and urged by a spring 96 into a position in which its other arm 94 engages the back 54 of the camera housing. Alternatively, said projection may comprise a projecting end of a downward extension of a spring 64 provided for urging the container 2 towards an exposure gate 62 in the camera. In order to advance the leaders in turn from the opening 10, between pressure rollers 80 and through the aperture 82 to a point where they can be manually grasped, a pair of rollers 70 are provided which are arranged to be rotated anticlockwise as they are moved downwards upon actuation of a knob 74, a spring 76 wrapped around the common shaft 72 of said rollers causing their rotation and also returning them to their rest position. The back of the camera is hinged at 56. The photographic sheets referred to comprise a photosensitive sheet 16 and a sheet 18 adapted in cooperation with the pressure rollers 80 to spread processing fluid from a rupturable container between the superimposed sheets, in known manner.

Abstract: 1,145,232. Stapling tools. SENCO PRODUCTS Inc. 19 Sept., 1967 [23 Nov., 1966], No. 42628/67. Heading B4C. A pneumatically-actuated fastener driving tool, such as a stapler, comprises a driver piston 32 reciprocable in a cylinder 22, a staple magazine 16 and a control means 46 including a main valve 72 for controlling the flow of pressurized air to the cylinder and actuated by a control piston 90, the air fed to and exhausted from the control piston being controlled by means of a slide valve 96. The tool is provided with an air reservoir 18 communicating with the working cylinder 22 via the control means 46 and a passage 50. To operate the tool, a trigger-actuated valve 54 is operated, thereby allowing air to flow via passage 56, ports 98 to lift the slide valve 96 so as to allow the air to act on the control piston via ports 106. The latter then rises to first close an exhaust slot 70 leading into an exhaust tube 52, further movement causing the piston to lift the main valve 72 off its seat and allow air to pass from the reservoir 18, passages 48, 50 into the cylinder 22 and so drive the piston 32. During the driving stroke air flows via ports 108 in the body of the main valve, a port 110 in a hollow stem 76 and past an adjustable throttle needle 86 to act on the slide valve 96. The slide valve then moves downwardly to close off ports 106 from the pressure ports 98 and so allow the space below the control piston to be exhausted via ports 106, 112 and 114. The control piston then returns to the position shown in Fig. 2, wherein the main valve is re-seated and the air above the driver piston 32 is exhausted via passage 50, slot 70 and tube 52. The driver piston rises under the action of air compressed in a chamber 36 during the working stroke. The tool will continue to recycle as long as the trigger valve 54 is actuated.
