Title: Improvements in or relating to range finders
IPC: G01C3/16
Filed: 1944-04-06
Abstract: 585,820. Range-finders. INTERNATIONAL POLAROID CORPORATION. April 6, 1944, No. 6516. Convention date, March 2, 1943. [Class 97,(i)] A stereoscopic range-finder is provided with a pair of relatively laterally displaceable graticules right-eye and left-eye images of which are superimposed on the field of view of the observer, and provision is made for substantially blocking from each eye of the observer the image intended to be seen by the other eye. Polarized light may be used to effect the blocking. In the graticules shown in Fig. 3, shapes A, A<1> are formed, one each, on the inner faces of sheets 22, 24 formed of light-polarizing material with the axes at right angles to one another as indicated by arrows 32, 34. Analysers 26, 28, Fig. 2, are positioned with their transmission axes parallel to the arrows 34, 32 respectively, so that the left eye will see the image of shape A only, whilst the right eye will see the image of A<1> only. One sheet is moved laterally with respect to the other by gearing having a pointer 44 and scale 45 with which a vernier may be associated. The range-finder is adjusted so that the stereoscopic graticule image, visible through transparent mirrors 15, is in line with the object in the field of view being ranged on, which object is seen by reflection from mirrors 12 and 15, and the knob 40 is then turned to bring the image apparently into the plane of the object, the range being read directly from the scale. In another form, not using polarized light, opaque marks may be formed on transparent sheets and a partition 50 provided between the sheets and the lens. A pair of relatively movable light sources may be used in place of the single source 20 and in this case the graticules may be dispensed with. The invention may be applied to instruments not provided with means for increasing the interocular distance.

Abstract: 586,507. Gyro - magnetic compasses. THOMAS, I. L., and ROBERTS, G. E. March 15, 1945, No., 6603. [Class 97 (iii)] To eliminate errors due to inclination of the pendulous magnetic means, i.e. needle, earth inductor, or fluxgate elements, a switch or other means actuated by displacement of the gyroscope (with its spin axis lying in an E-W direction) relative to apparent gravity or to the gyro frame, retards or prevents the control of the gyroscope from the magnetic means, As shown, the precessing torque is applied by a coil 24 fixed to the vertical ring 25 and co-operating with a pair of arcuate permanent magnets 22 extending, with like poles adjacent, from the inner gimbal 23. Spaced resistance elements 52, Fig. 3, mounted on the ring 25 and connected as shown may co-operate with a contact arm 53 mounted on the gimbal 23 so that movement of the latter relative to the ring 25 first shunts with resistance 52 and then short-circuits the coil 24. In a modification, the coil 24 may be short-circuited by a relay operated by flow of current in the electric anti-topple means. In further modifications, the arm 53 may be replaced by a pendulous contact arm or the coil 24 short-circuited by a mercury switch mounted on the gimbal 23. Specification 586,506 is referred to.

IPC: C07C17/38
Filed: 1932-03-05
Abstract: a  - Phenylethylene - a b  - dichloride is isolated from its mixture with a -phenylethylene-b -chlorhydrin, obtained when hypochlorous acid is added to styrol, by dissolving the mixture in an organic solvent non-miscible with water, treating the solution, in the presence or absence of water, with an alkali metal oxide or hydroxide without allowing it to boil, and finally fractionating the product after freeing it from alkali.  When one of the components of the starting mixture is present in excess, it may itself function as the solvent.  The a -phenylethylene-b -chlorhydrin becomes converted into phenylethylene oxide which can readily be distilled away. Solvents mentioned are benzene, tetrachlorethane, trichlorethane, chlorobenzene, ether, and benzyl alcohol.  Examples are given. It is stated that a -phenylethylene-a b -dichloride is converted into a -phenyl-b -chlorethylene when boiled with aqueous or alcoholic alkali in the absence of a water-insoluble organic solvent.

Title: Improvements in or relating to hardening cylinder bores and other surfaces by the electrodeposition of a wear-resisting metal, such as chromium
IPC: F16J10/04
Filed: 1944-04-17
Abstract: 583,872. Electroplating. LISTER & CO., Ltd., R. A., and WERRETT, R. April 17, 1944, No. 7098. [Class 41] [Also in Group XXII] The production of a hardened surface on a cylinder bore 12, or similar article, is effected by electro-plating the surface with a wear resisting metal, preferably chromium. The surface 10 is first shaped so that its diameter d<1> is more than the required diameter by an amount 2r., r being the thickness of the deposit, the resulting surface not being highly-smooth. It is then roughened by knurling. Inaccuracies, such as high spots, are removed by lightly polishing and honing the surface which is then electro-plated. The plated surface 20 is finally ground or polished, thus providing a finely pitted surface 24. If desired, the roughening process may be carried out after an initial light deposit of chromium has been applied, a final deposit being applied afterwards. Specification 521,572 is referred to.

Patent GB-386473-A (GB)
Title: Improvements in or relating to printing by means of multi-coloured printing blocks in a rotary printing machine
IPC: B41F17/00
Filed: 1932-03-11
Abstract: 386,473. Printing-machines ; feeding webs. SARK, A., 3, Rue de la Viabert, Brotteaux, Lyons, France. March 11, 1932, No. 7336. [Classes 100 (i) and 100 (ii).] In a rotary web-printing machine, a water-moistened web is printed by means of a water-soluble, polychromatic, solid printing-block fixed to a printing-cylinder, around which the web is passed and against which it is pressed by one or more impression rollers so arranged that the web wraps round not more than half the periphery of the printing-cylinder. The material to be printed may comprise fabric, paper, straw, or a warp, and is led from a roll A over a smoothing roller B to moistening rollers C, of which the lowest runs in a bath of water. The pressure between the rollers is adjustable by weights E and the material may be lead either directly through the bath or between the rollers as desired. The material passes over a second smoothing roller N to the printing roller L carrying the solid colouring matter, which coacts with resilient impression rollers K the pressure of which is varied by weights M. A strengthening backing web may be fed in from a roll P and rewound on a roll R. The material after printing passes over rollers O, Q<1> to a drying device S for drying the material and thence to folding apparatus T. The drying device S may comprise heating elements or fans whose action may be varied as by altering their distance from the web. The middle roller C and the printing cylinder L have a common drive from a toothed wheel H which drives the roller C through a change-speed gear F and the printing-cylinder L through a similar gear F<1>, so that the relative speeds of the moistening and printing rollers can be suitably adjusted for tensioning. The distance between the printing-apparatus and the moistening-apparatus is made variable by mounting the former upon a frame g which slides upon the base u of the machine, thus permitting the slight drying which occurs between the two operations to be varied. The printing-rollers L, K are removably mounted in stub shafts attached to the machine frame, by securing the ends of the roller shafts in bearing claws on the stub shafts, and holding them in position by flat covers, which are attached by screws to the bearing claws and engage a flat surface on the roller shafts. The smoothing- rollers B, N contain in their coverings axially displaceable bars which over one-half of the periphery of the rollers move towards the ends of the rollers and over the other half of the periphery towards the middle portion of the rollers.

Filed: 1924-03-24
Abstract: 213,570. Seiliger, M. March 26, 1923, [Convention date]. Cylinders, varying clearance of; four-strokecycle engines.-Engines which are supplied with charging air from a compressor have the clearance variable to maintain constant compression ratio in the cylinder, the variation in the clearance and the adjustment of compressor pressure being regulated by hand. As shown applied to a four-stroke Diesel engine, a piston 12 is used in an additional clearance space 11. The piston 12 is connected through chain gear to a counterweight; the position of the piston is varied by adjusting the quantity of fluid contained in the space 18 behind the piston. The compressor supplying the air is driven from the engine through a clutch which may be opened to allow the engine to work without pre-compressed air. The regulating handles for the compressor suction and for the control of the fluid in the space 18, together with a manometer for the compressor delivery and an indicator for the counterweight, are mounted on a single control board. The adjustable piston may be in the main cylinder. The Specification as open to inspection under Sect. 91 (3) (a) states that the cylinder cover can be adjusted to vary the clearance. This subjectmatter does not appear in the Specification as accepted.
