Title: Improvements in Marine Lights.
Inventor: VIALET-CHABRAND LUCIEN
IPC: B63B51/04
Filed: 1919-06-10
Abstract: 129,263. Chabrand, L. Vialet-. June 29, 1918, [Convention date]. Phosphoretted hydrogen and self-lighting signals.-A marine light comprises a chamber 1 containing calcium carbide, a superimposed chamber 2 containing calcium phosphide, and a watertight chamber 3 surrounding the phosphide chamber only and serving to float the apparatus: the parts are arranged so that phosphuretted hydrogen is produced at a very low pressure, and acetylene at a much greater pressure. The water reaches the carbide and phosphide respectively through an orifice 11 and a tube 7, and through an orifice 9 and a tube 8. The phosphoretted hydrogen escapes through an orifice in the top of the chamber 2 and ignites the acetylene which issues from one or more orifices 5 in the top of the tube 4. The tube 7 is surrounded by a perforated tube 21, and a perforated cone 20 surrounds the upper end of the tube 8. The orifices for the entry of water and the escape of gas are normally sealed by soldered strips which are detached by hand or automatically just before the device is used. The buoy may be attached by a cord to a salvage device if it is desired to illuminate and the sealing- strips may be provided with rings attached by cords of unequal length to the ship, so that when the salvage device is thrown overboard, the buoy is dragged after it and the sealing-strips torn off in succession.

Abstract: 857,802. Bundling machines. POWER STRAPPING SYSTEMS Ltd., [formerly POWER & SONS (BOX STRAPPING) Ltd., F. A.]. April 8, 1959 [May 8, 1958; Aug. 8, 1958], Nos. 14716/58 and 25452/58. Class 94(1). A device for obviating twisting of binding metal being fed to a package tying machine of the kind in which the metal is looped about the package by a rotating ring, comprises a coil holder 14 rotatably mounted on a shaft 5, the shaft being driven from the tying machine and having secured on it a driving arm 12. The arm 12 is connected to one end of a V-belt 16 passing round a pulley 15 fixed to the holder and is joined to a tension arm 13. The arm 13 pivots freely on the shaft 5 and is connected to the arm 12 by a spring 17, the latter tightening the belt about the pulley and thus forming a driving connection between the arm 12 and the holder 14. The arm 13 has a counterweight 18 against which abuts an adjustable stop 19 to limit relative movement of the two arms. The drive to the shaft 5 includes a pin and part annular groove type lost motion connection between the shaft and a driving sprocket 8, Fig. 3 (not shown). When there is no demand for binding metal the holder and shaft are connected and the whole assembly rotates in unison with the tying ring. When metal is drawn off, the arm 13 is displaced by the tension relative to the arm 12 to slacken the belt and enable the holder to unwind its coil. The lost motion arrangement permits the assembly to move independently of the tying machine drive through a limited angle to take account of sudden demands for metal. Specifications 523,829 and 777,965 are referred to.

Title: Improvements in or relating to aerial torpedoes, bombs and the like
IPC: B64D1/04
Filed: 1929-05-21
Abstract: 317,774. Macmillan, N. May 21, 1928. Aircraft coupled in pairs or trains. -An aerial torpedo or bomb a to be discharged from an aeroplane f is provided with aerofoil supporting surfaces, the ratio of the superficial area of which to the total weight of the bomb is substantially the same as the ratio of the superficial area of the. wings of the aeroplane to its total weight. It results from this that the load of bombs has little effect on the flight capacity of the aeroplane other than a slight reduction of speed due to increased head resistance. The bomb may be released when the aeroplane is gliding more or less directly towards the target, whereupon the bomb will continue in the same line. The bomb may have a slightly smaller ratio of weight to supporting surface to facilitate " taking off," and may then be released upwardly by causing the aeroplane to travel slightly faster for a given gliding angle or on a steeper path for a given minimum speed. The bomb may be fitted with controlling devices operated by a gyroscope or an aneroid device, or by " wireless " or light beams; and may also be provided with propelling means. The bomb may be used for attack, or for the supply of ammunition, stores, or mails. The bomb is placed above or below the aeroplane, for example on struts b on the aeroplane or on the bomb, and is held in place and released by means of bolts d. when the bomb is suspended below the aeroplane, a supporting hook is used in addition to the releasing bolt.

Abstract: 841,255. Measuring and testing yarns. DUNLOP RUBBER CO. Ltd. May 9, 1957 [May 15, 1956], No. 15043/56. Class 120(3). [Also in Groups XIX, XXXV, XXXVIII and XL(b)]  Apparatus for continuously determining the change in length under load of a filamentary material 5 comprises three pulleys 1, 2, 3, between which the material is supported in the form of loops 10, 14, means 6, 7 for driving the second and third pulleys, 2, 3, means for applying a load 9 to the first loop 10 and a greater or lesser load 12 to the second loop 14, means 15, 16; 20, 21, for each loop responsive to a change in length of the loops for varying the speed of the pulley driving means 4, 6 so as to maintain the loop lengths substantially constant, and means (not shown) for determining the difference between the length of material passing through one loop 14 and the length of material passing through the other loop 10 in unit time. In the embodiment shown, the load 9 is just sufficient to hold loop 10 taut, and the load 12 is 20 lbs. thus giving a tension of 10 lbs. in each strand of loop 14; and photo-electric devices 15, 16; 20, 21 (see Group XXXV) control the lengths of the loops 10, 14 by altering the speed of rotation of motors 4 and 7 and thus of pulleys 1,3. A motor 6 drives the pulley 3 through an epicyclic gear train 8, influenced by the motor 7. The length of material passing through one loop in unit time is measured by measuring the speed of the material. This is accomplished by photo-electric devices 28, 29: 30, 31, (see Group XL(b)) which produce pulses corresponding to the speeds. If the number of pulses produced in a unit time are C0, C10 respectively, then C10-C0/C0 is a measure of the extensibility of the CO material. This can be found by producing a voltage V 1  corresponding to C0, and a voltage V 2  corresponding to C10-C0, and then comparing V 1  and V 2  on a potentiometer recorder (see Group XXXVIII). An alternative method is to count the number of pulses from cell 29 in excess of one thousand in the time taken for one thousand pulses to be produced by cell 31. This is proportional to C10-C0/C0 and thus to the extensibility. CO The device may be inserted in a thread processing line and used to control one or more of the variables of the processing machine. Various modifications in the means of driving the pulleys are described, the mechanism to maintain the lengths of the loops constant may be mechanical or electromagnetic, and the measuring may be accomplished by counting the revolutions of the second and third pulleys. The error caused by the tension in the first loop not being absolutely zero may be allowed for by a correction factor based on the mean stress strain curves of the material, and there may be a time lag in the electronic counting device so that the same portion of thread is measured at each point. The apparatus may be used to measure the extensibility of pre-stressed thread, or the recovery characteristics, by using various weights on loop 10, instead of the light roller 9.
