Abstract: 250,419. Pescara, R. P. June 8, 1925. Actuating pumps by fluidpressure motors.-In a directacting air compressor the free piston 14 moves inside a cylinder 11 which reciprocates freely in a frame 10, a series of spring buffers 70. 71 tending to keep the cylinder in a mean position. The cylinder is closed at its ends by heads 12, 13, the head 13 having automatic suction valves 50 for the compressor side of the cylinder. The compressed air is delivered through cylinder ports 56, and delivery valves 53 to a collecting ring 51 and thence to a reservoir 55. The combustion chamber head 12 carries a sparking plug, an air admission valve 18 and a rich mixture valve 17 communicating through the telescoping piping 19 to a carburettor 20. The exhaust ports 43 in the frame are controlled by ports 42 in the cylinder. A trip magneto 47 is worked by the spring detent 48. To start the engine the sparking plug is removed and the piston 14 moved to the position shown by a rod inserted in the plug hole. Fuel is injected into the air and then the combustion space is closed by replacement of the plug. One of the valves 53 is lifted and compressed air from the reservoir pushes the piston in the direction of the arrow 57 and the cylinder in the opposite direction. At a particular point in the stroke the magnet is tripped, an explosion takes place, and the movements are reversed. Air in front of the piston is compressed and some is delivered to the reservoir, a certain amount being retained to form a buffer which returns the piston on the succeeding stroke.

Abstract: 1424767 Automatic control of metal-working machines OSOBOE KONSTRUKTORSKOE BJURO STANSKOSTROENIA 28 March 1973 14866/73 Heading G3N The program controlled movement of a spherical ended cutter is interpolated by considering the surface to be cut as being formed of surfaces of bodies of rotation conjugate with flat portions located orbitarily in space. As shown, a perforated tape 2 is read by a reader 1 to derive information relating to the path to be travelled by a spherical cutter in working surfaces expressed as planes perpendicular to the ones of revolution of bodies of rotation and orbitarily located congruent flat portions. For arcs the co-ordinates of the beginning and end with respect to the centre of the arc are given together with the cosines of the angles between machine ones and the vector perpendicular to the plane of the arc. The output of the reader 1 is fed through an information introducing unit 3 to a correction unit 4, connected to a control panel 5, the output of which is fed to an interpolator 6, supplying positioning signals to a unit 7 controlling the drives, (not shown), of the associated milling machinery. The interpolator 6 comprises a memory 8 an arithmetic unit 9 and a control unit 10 which are interconnected to perform for the interpolation of an arc trial steps from the evaluation of which is determined the trial step to be used as the actual interpolating step. The trial steps are effected in a predetermined sequence depending on the serial number of the octant in which the arc being reproduced is located as well as the direction of tracing of this arc.  The unit 4 includes a memory unit 16 an arithmetic unit 17 and a control unit 18 interconnected to modify the programmed geometric parameters for the dimensions of the actual dimensions of the spherical cutter being used in the milling operation.

Abstract: 1378577 Photographic silver halide materials EASTMAN KODAK CO 30 March 1972 [12 April 1971] 15100/72 Heading G2C A light-sensitive photographic material comprises a support carrying at least one silver haloiodide emulsion layer and over this emulsion layer a silver precipitating layer and a low sensitivity fine-grain silver halide layer in which the halide is chloride and/or bromide, the grain size is less than 0À1 micron and the speed at least 50 times less than that of the silver haloiodide layer. The silver precipitating layer may comprise metal sulphides, polysulphides, selenides or polyselenides, thiourea, stannous halides, heavy metals, particularly Carey Lea silver, or their salts and fogged silver halide. As the fine-grain silver halide layer a Lippmann silver bromide emulsion having a grain size of 0À01 to 0À05 micron and a speed at least 100 times slower than the silver haloiodide layer is preferred. In one embodiment the fine-grain emulsion is adjacent the silver haloiodide layer and the silver precipitating layer is coated thereover. The fine-grain emulsion prevents iodide ions migrating from the haloiodide layer into the developer solution and inhibiting development while the silver precipitating layer prevents silver plating out from the fine-grain emulsion on to rollers used to transport the material through the developer solutions. In an alternative embodiment the silver precipitating layer is between the fine-grain emulsion and silver haloiodide layer and prevents complexed silver halide migrating from the finegrain emulsion into the silver haloiodide layer when the material is developed in a solution containing a silver halide solvent.

[Class 80 (ii)] [Also in Group XIX] A device for measuring and indicating the ratio of the speeds of rotation of two shafts comprises a sphere. S, Fig. 2, set in rotation simultaneously by two rollers 1, 2, each driven by one of the shafts, and one or two swivelling castors 4 indicating the axis of the resultant rotation of the sphere and, consequently, the desired speed ratio. The castor 4, whose axis 0 passes through the centre of the sphere, may carry a pointer indicating against a scale, or the pointer may be driven through 2 to 1 step-up gearing so that the same scale is applicable when the rotation of the sphere S is reversed. Instead of a pointer and scale an arm may be arranged to pass over a series of contacts and may control servo-mechanism for controlling gear changing. Thus, in Fig. 7, a hand-operated controller 14 is set to select a particular gear and when the arm 17, driven by the control device, reaches the corresponding contact I<11> to IV<11>. the servo device I to IV is actuated to change the gear. The control device may also control the speed of the engine to obtain the desired synchronization. A column of contacts V<1> to IX<1>, X and XI, Fig. 8, is positioned at one of four stations I<11> to IV<11> on a drum 19 according to the gear to be selected. An arm 18, driven by the control device, completes a circuit to an accelerator solenoid 21 controlling the throttle 24 when it lies above the position corresponding to the selected gear, and a speed reduction solenoid 22 is energized when it lies below. When the arm 18 reaches the appropriate contact I to IV, the servo-mechanism is operated as before.
