Abstract: 544,004. Protecting metal surfaces; anti-corrosive paints. BRITISH IRON & STEEL CORPORATION, Ltd., and MAYNE, J. E. O. June 18, 1940, No. 10529. [Class 95] Metal surfaces are protected against corrosion by applying thereto an emulsified oil paint comprising a drying oil, water, and an emulsifying agent which is a salt of a weak acid and a weak base, decomposes at the temperature at which the paint is used, and yields products of decomposition which are either volatile at said temperature, or are both hydrophobic and miscible with the oil, the paint being free from constituents which, after drying, remain capable of absorbing moisture or which render the film pervious to water. The paint may be applied to the metal surface while the latter is wet. Specified emulsifying agents are the ammonium, mono-methyl ammonium, mono-ethyl ammonium and di-methyl ammonium salts of fatty acids, and these may be added as such, or may be prepared in situ in the paint. The drying oil used may be resin-modified, and the fatty acid used in the production of the emulsifying agent may be obtained by the hydrolysis of animal or . vegetable oils. Examples are given of paints prepared from:- (1) linseed oil, water, driers, hydrolysed linseed oil, ammonia, and red lead or red oxide of iron; (2) linseed oil, water, driers, hydrolysed linseed oil, ammonia, casein and zinc dust. Specification 420,760, as open to inspection under Sect. 91, and Specification 183,177, [Class 95], are referred to.

Abstract: 106,813. Dewson, E. H. June 1, 1916, [Convention date]. Fluid-pressure.-An electropneumatic train brake system in which there is no trainpipe comprises a distribution valve provided with a restricted passage to permit graduated application, and a wide port for emergency applications. A slide valve 26, Figs. 2 and 3, has tha chamber 27 thereof constantly open to the main reservoir 2 by passages 28, 29, and is adapted to connect the brake-cylinder passage 49 either with exhaust port 52 or chamber 27. The brake cylinder connects with passage 49 by pipe 43, passage 42, and chamber 39 of a second slide valve 38. In the normal pcsition of this valve, the passage 42 and chamber 39 communicates only through the choke-plug 41; but in the emergency position of the valve 38, wide ports 54 are also opened. The main slide valve 26 is controlled by the electric valves 31, 33 adapted to connect the piston chambers 23, 25 either with the fluidpressure supply from valve chamber 27, or to exhaust ports 48, 50 by passages 30, 45 and 44, 32. The valve 26 assumes the lap position shown, under the action of springs 46, 47 when the valve magnet 8 is energized and the valve magnet 10 de-energized, piston chambers 23, 25 and valve chamber 27 being then charged with fluid pressure. A service application is ob. tained by de-energizing magnet 8, thereby opening chamber 23 to exhaust and causing the slide valve 26 to uncover the passage 49 to the valve chamber 27. For emergency applications, the magnet 6 is de-energized as well as the magnets 8, 10, whereby the chamber 36 of the slide valve 35 is connected to exhaust port 53, and the wide ports 54 are opened for the passage of air to the brake cylinder. Release of the brake is effected by energizing magnets 8, 10, whereby piston chamber 23 is charged and chamber 25 exhausted, causing the slide valve 26 to move to connect the passage 49 to exhaust port 52. The magnet 6 is also de-energized to open the wide ports 54 and allow rapid discharge of the brake cylinders. The magnets 6, 8, 10 are connected to the train wires 7, 9, 11 and to a common return 12. Wire 9 is connected to the controller contact 19 through emergency train wire 13 and contacts 20 at the ends of the vehicle.

Abstract: 707,246. Mine-hoists. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 29, 1952 [May 10, 1951], No. 11050/51. Class 78 (5) A control system for mine-hoists and the like having a mechanical linkage including a pivoted lever for transmitting the movements of the driver's control lever to the speed controller includes an auxiliary device effective according to its position to enable either manual or automatic working to be obtained which, when the device is in the manual position locks the pivot of the pivoted lever whereas when in the automatic position the pivot is left floating so that movements of the speed controller are not transmitted back to the driver's control lever. As shown the driver's control lever 1 is connected to the speed controller by a linkage including a lever 41 and a pivoted lever 46, this lever being pivoted on a pin 47 passing through slots in a bracket 49 and in both sides of a double-sided member 52 of a toggle link 51, 52. The top member 51 of the toggle link is solid with a bearing pin 50 to which is secured a lever 53 connected by linkage 60, 59, 58, 54 to the auxiliary control device 4. In the position shown, with the controls set for manual operation, the pin 47 is forced to the bottom of the slots in the bearing bracket by contact with the tops of the slots in the toggle link 52 and functions as a normal fulcrum for the pivoted lever 46. On moving the control 4 from the "manual position rotation of the bearing pin 50 breaks the toggle and the pivot pin 47 is free to move in the bearing bracket slots. The movement of the lever 4 is normally limited by engagement of the link 59 with fixed stops 62, 63 but further movements. e.g. from the central " semi-autoimatic position to the " fullyautomatic " position may be permitted by a spring-link 58. Specification 707,244 is referred to.

Title: Improvements in or relating to transducing apparatus for exciting or responding to lamb waves
IPC: G01N29/24
Filed: 1947-04-25
Abstract: 654,247. Testing materials by sonic vibrations. SPERRY PRODUCTS, Inc. April 25, 1947, No. 11104. Convention date, May 21, 1946. Addition to 615,684. [Class 118 (ii)] [Also in Group XXXIX] Waves, known as "Lamb" waves, are induced in a plate by apparatus substantially as described in the parent Specification, comprising an elec. tromechanical transducer having means for coupling it to the plate by a liquid medium, the transducer being inclined to the plate such that the wave front of mechanical vibrations from the transducer will strike the plate at an angle with the plate surface determined by the formula where Vp is the phase velocity of the Lamb wave, VL is the velocity of the wave in the liquid, and α is the angle measured from the normal at which the wave enters the plate. As shown, the transducer comprises a housing 20, filled with liquid, with its open end in engagement with a plate 10, and a crystal 30 adapted to be tilted about a pivot 31 within the housing. The forward edge of the casing does not contact the plate, and this gap is closed by a rubber &c. strip 25. In a modification, this gap is not closed, and means is then provided for supplying liquid to the housing to keep the crystal immersed. Waves A from the crystal strike the surface 21 to set up Lamb waves in the plate which travel in the direction B. The contacting edge 22 of the housing is sufficient to damp waves in the opposite direction. A similar arrangement along the plate 10 may be arranged to receive the Lamb waves. The type and mode of Lamb waves generated will depend upon the inclination of the crystal 30 and the dimensions thereof, and the product of the wave frequency and plate thickness must be a predetermined value. A given type and mode of wave in a plate 10 will on striking a fissure or other defect within the plate generate other modes or types of waves, so that by setting the receiving crystal in the second housing along the plate at an angle such that it will receive modes different from the mode transmitted by the first crystal 30, fissures can be detected. If desired, the waves from the crystal may be arranged to strike an end of the plate 10. In a modification, the transmitter crystal is arranged on the bottom of a container filled with liquid, and the plate is held in the liquid at the appropriate angle. In a further modification, based on the principle that the difference in phase velocities of different types and modes of Lamb waves will result in points of interference, and, hence, points of maximum and minimum vibrations of the plate, the thickness of a plate may be determined. Two different types and modes of waves are induced, and the receiver crystal moved along the plate to detect the points of minimum pick-up, and the thickness of the plate can then be determined by calculation; or fixed transmitters and receivers may be used and the finger of the operator moved along the plate to observe the points of " no damping " on the receiver.
