Title: Improvements in and relating to recording mechanism for high pressure investigations in ordnance and the like
IPC: G01L23/00
Filed: 1921-06-21
Abstract: 189,163. Webster, A. G. June 21, 1921. Indicating, optical devices for; photographic recorders.-Relates to recording apparatus for use in pressure and trajectory investigations in ordnance. A frame 7 fitted to the breech of the fire-arm has a heavy screw 9 ending in a surface of revolution, against which bears a hardened steel cap 11 with handle 12 and provided with two bearing surfaces 14, 15, against which the pressure indicating and recording spring 20 is pressed by a plunger 3 in a bore in the test arm The spring 20 is of high-carbon or alloyed tool steel of high resistance to deformity, so as to bend nearly proportionally to the stresses applied. The end of the spring may be polished optically, or have cemented to it a mirror, in either case preferably concave. The motion may be observed on a screen at a, or record may be made on a moving film by means of an arc lamp A, Fig. 1, and collimator L with a timing mark by a vibrating reed 57 electromagnetically operated. The source of light is preferably an arc lamp, close in front of which is placed a screen 26 of refractory material such as platinum or tungsten with a pinhole in line with the collimator lens L. To prevent fogging, the film circuits are arranged as shown to open the camera shutter 43 by means of its solenoid 49 before the charge is fired, and to open the light shutter 29, Fig. 10, for only one turn of the drum 40 carrying the film. The key 70, Fig. 1, when closed, energizes magnet 33, Fig. 10, to close the light shutter 29 and opens the camera shutter 43, at the same time energizing a solenoid 75 to rock a lever 76 so as to raise a slide 77 under one end of the axle 50 of the drum 40 which runs in ball bearings. The drum is driven by a constant speed motor. On the slide 77 are ways 79 on which a straight conductor 80 is arranged to slide parallel to the axle of the drum under spring control. On the axle is fitted a non-conducting worm 81, on one turn of which a conductor is laid, during the contact of which with the conductor 80 a magnet 32 stronger than the magnet 33 is energized to open the light shutter. The travel of the projectile along the barrel and along its trajectory may be recorded on the same film. For the former the barrel is wound with a coil p, Fig. 11, connected to a generator and at chosen points with many-turn coils m<1>, m<2>, m<3> of fine wire connected to a mirror or string galvanometer; and for the latter accoustically operated devices of the type described in Specification 187,655, [Class 118 (ii), Signals], are arranged near the trajectory and adapted to energize a magnet w<1>, Fig. 12, to rock a recording mirror. In a modification, a tranversely arranged spring 20, Fig. 13, may record on a fixed plate P an indicator diagram of pressure against recoil. In a further modification, a spring 20 mounted axially on a fire-arm which recoils against a stiff spring 90 carrying a mirror 91 gives a pressure recoil diagram on a plate P<2>.

Variable-speed gearing.-The driving and driven shafts are arranged eccentrically, one carrying an internally threaded drum engaged by teeth on slides engaging axial slots in a drum on the other shaft, the speed being varied by adjustment of a stationary inclined guide against which the slides bear. The driven shaft 13 carries a drum C with a multi-thread screw D engaged by teeth on slides G engaging axial slots in drum F on the driving- shaft A. Blocks H are secured to the slides G by pawls P and ratchet-teeth O and carry rollers J engaging a curved control guide I adapted to be rotated upon its pivot 2 in the fixed casing X so as to be parallel to the threads D or in the plane of rotation or in any intermediate position, thus varying the speed between zero and the full speed corresponding to the ratio of diameters of the driving and driven parts. In order to ensure that the slide teeth engage properly with the threads D during each revolution of the shaft A, when the slides leave the area controlled by the guide I they are engaged by a guide K with a spring- pressed pivoted end L which presses the slides into engagement with cam-surfaces parallel to the threads D formed on blocks M turning with the drum C. The guide K, L may be replaced by springs acting separately on each slide. To ensure that the blocks H engage with the fixed end of the guide I, the pawls P are disengaged from the ratchets O by an incline T on the guide I just before the slides disengage from the screw D, and the blocks are moved in the required path between guides V, W on the casing X. The pawls P are returned to a position to lock together the slides G and blocks H by a surface R, Q on the casing X. The rollers J and pawls P may be carried on opposite arms of bell-crank levers pivoted on the blocks H.

Abstract: 612,894. Decorating glass. JOHNSON, MATTHEY, & CO., Ltd., and WYNN, N. June 5, 1946, No. 17080. Drawings to Specification. [Class 56] A design is produced on a transparent heatresisting base in simulation of stained glass by applying by the silk screen printing method an opaque coating of vitrifiable enamel to cover the portions corresponding to the outline, the glass joints, the leaded lines, and other opaque areas if required, drying, applying a transparent or translucent coating of liquid lustre of the required colour to the remaining portions, and finally firing. The enamel may consist of a lead borosilicate or lead alkali metal borosilicate flux coloured by metal oxides, and applied as a paste with e.g. a cellulose compound and amyl lactate. The liquid lustre which may be applied by painting or spraying may consist of a solution of the resinate or sulphoresinate of iron, titanium, bismuth, tin, zinc, &c., to which may be added the sulphoresinates of precious metals with essential oils, aromatic alcohols, aromatic hydrocarbons, or chlorinated aliphatic hydrocarbons as solvent. The base is finally fired at between 500‹ and 600‹ C. and may be additionally fired before the liquid lustre is applied. A diffused effect may be obtained by firing a thin layer of a transparent enamel containing a small proportion of an opacifying pigment on to the untreated side of the base, which may be covered on one oi both sides by a protective undecorated sheet. A single panel may form the window or a series of panels may be assembled together in a framework.
