Title: Improvements in feed mechanism for the tool slides of automatic lathes and like machines
IPC: F16H25/08
Filed: 1954-05-26
Abstract: 771,689. Lathe-details. LETAL, J. May 26, 1954 [May 27, 1953], No. 15512/54. Class 83 (3). Feed - mechanism for the tool-slides of automatic-lathes &c. comprises a control-cam and an adjusting - member, the setting of which can be continuously varied to control the time during which the tool is operative on the work, and a second adjusting-member for the continuouslyvariable adjustment of the length of the working-stroke of the tool, the adjustments being independent of one another and having interposed between them a sliding or rocking member which has a constant amplitude per revolution of the cam-shaft. A main cam-shaft 1 driven at constant speed carries a cam 2 which may be adjustable thereon for varying the timing of the machine. The cam, which is arranged for depth-of-cut feed, moves a twoarmed lever 3 through a follower-roller 4. The upper end of the lever is slotted for adjustment of a connecting-rod 5 which transmits motion to a lever 6. The free-end of the latter carries an adjustable stop which bears against a spring- pressed slide 7. This slide carries a plate 10 with an incline GI, which determines the quick approach of tool to work, and also carries an adjustable segmental-plate 9 with a further incline I, II which determines the cutting-stroke. Motion is transmitted from the inclines through a follower-roller 11 to a lever 12 and thence to the tool-slide 13. An adjustable feed transmission for the longitudinal movement of a tool is described also. Specifications 430,243, 678,749 and 678,750 are referred to.

Filed: 1924-06-30
Abstract: 240,525. Hodgson, J. L. June 30, 1924. Integrating.-In apparatus of the type in which a pivoted arm, moved in accordance with the variable to be integrated, carries a contact wheel driven by a constantly rotated friction disc to actuate a counter mounted on the arm, the contact wheel is so mounted that its axis is separated from the pivot of the arm by a distance which differs from the distance between the said pivot and the centre of the disc so that the speed of rotation depends, to a substantial degree, upon the angular setting of the wheel as well as upon the radial distance. To facilitate turning of the arm the contact wheel is provided with a series of rollers on its periphery and to prevent inaccurate readings below a certain minimum rate the contact wheel is rendered inoperative. As shown applied to a flow meter Fig. 1, the throat and upstream pipes 22, 23 of a Venturi tube 21 are connected to the limbs or chambers 2, 3, respectively of a U-tube. The chamber 2 is provided with a float 1 connected by a link 6 to an arm 5 secured to the axis of a cam 7, the axis passing through a gland in the casing of the chamber 2. An arm 9, pivoted at a point coincident with the centre of a counting device 10, carries a roller 8 engaging the cam 7, a counterweight 18, and a frame 11. The frame 11 is provided with bearings for a spindle 12 on which is mounted the contact wheel 13 and the bevel wheel 15 that transmits the movements of the wheel 13 to the counter 10. The contact wheel 13 has around its periphery a plurality of rollers 14 as shown in Fig. 15. The wheel 13 engages a disc 20 adapted to be driven at a constant speed. A pointer or pen arm may be provided on the frame 11 to move over a scale or recording surface for indicating or producing a permanent record of the rate of flow. The chamber 3 may be shaped or uniform and the shape of the cam varied so as to cause the arm 9 to move a distance proportional to the square root of the flow. Owing to the difficulty of shaping the cam to give accurate readings below a certain minimum means are provided for rendering the contact wheel inoperative. This means comprises a lever 43, Figs. 13 and 14, with upturned end 47 for engaging a toothed wheel 48 on the spindle 12. The lever 43, which is pivoted at 44, is controlled by a spring 46 and screw 45.

Abstract: 1420902 X-ray tomographic apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 April 1974 [13 April 1973] 15843/74 Heading H4F An X-ray tomographic apparatus in which video signals corresponding to the images of different layers in an object are derived by a television camera by moving the X-ray tube to different positions and in which these video signals are stored and/or displayed with their corresponding images superimposed, wherein the shifting of the superimposed images relative to each other in dependence upon the respective analysed layer positions in the object is effected by controllably delaying the synchronizing signal (i.e. the timing of the deflection voltages or currents) supplied to the storage or display means relative to the respective video signals. As shown a television camera 1 is directed at the output display screen of an X-ray image intensifier (not shown) and the video signals of each tomograph (i.e. layer in the object) are stored on a magnetic disc store 2, the camera and store being synchronized by horizontal and vertical pulses H 1  and V 1  from generator 3 supplied with clock pulses from a generator 4. Each video signal from store 2 is then transferred on to a storage tube 8 whose deflection is controlled by sawtooth voltage derived in device 7 from synchronizing pulses H 2  and V 2  which are delayed with respect to H 1  and V 1  by periods of time determined by a process control computer 6 supplied with the various geometric parameters (including X-ray tube position) which define the particular layer in the object being analysed, i.e. computer 6 determines the number of pulses from generator 4 which counters 5H and 5V count before output pulses H 2  and V 2  are delivered, the counters 5H and 5V being started by the pulses H 1  and V 1  respectively. Thus the separate images of the different layers may be successively written into the storage tube from the magnetic disc store with suitable horizontal and vertical shifts, the resulting composite image being displayed on monitor 9 or re-stored in store 2. If the video signals of the different layers are successively written in store 2 then these signals may also be individually displayed on monitor 9.
