Title: Improvements in or relating to Sonar Apparatus
Inventor: HALLIDAY WILLIAM
IPC: G01S15/42
Filed: 1965-06-23
Abstract: 1,156,322. Sonar systems. SMITHS INDUSTRIES Ltd. 21 June, 1966 [23 June, 1965], No. 26510/65. Heading H4D. Apparatus for indicating from which direction a sound wave echo is received comprises a plurality of elements arranged at or near the focal region of a spherical or circularly cylindrical reflector such that each receives echoes from a different direction within an angular sector, respective echo - detection channels coupled to the elements, and means for providing a direction representation in accordance with whichever channel detects an echo. In the sonar system of Fig. 1 a linear array of seventy transducers 1 mounted at or near the focal surface of reflector 2 can receive echoes from seventy directions simultaneously. The transducers are coupled to individual transmitting/ receiving channels 3, each of which comprises a switch 11 for applying a pulse of carrier-wave to the transducer from gated amplifier 12 and for passing any received echo through automatic gain-controlled amplifier 13 to display unit 8. The transducers 1 may be pulsed concurrently, sequentially, or with different carrier frequencies, the transmission being controlled by a unit 6 which also provides synchronizing signals to display unit 8. Display 8 may be (a) a cathode-ray tube to which the outputs of receiving channels 3 are connected in sequence, giving an intensity-modulated type-B range/ direction display, (b) a row of recording pens (20), (Fig. 3) respectively coupled to the receiving channels 3 and producing marks against a time-base provided by relative movement of a chart (21) or (c) a row of neon or gallium-arsenide lamps (22) (Fig. 4) coupled to respective receiving channels 3 and moved together over a rectangular display area (23). The transducer array of Fig. 1 may be used to provide a sector of search having its plane horizontal or, for searching a region of water adjacent the sea bed, having its plane vertical. In a modification (not shown), a two-dimensional array of transducers may be used instead of the linear array to provide a two-dimensional display of targets at a given range. The acoustic signals transmitted in this case may be continuous wave instead of pulsed, and the range at which targets are " in focus " may be selected by adjusting the position of the array with respect to the reflector 2. A stop, positioned at the centre of curvature of reflector 2, may be used to ensure uniform acoustic illumination across the effective aperture of the system. Display techniques involving real or simulated stereoscopic effects may be used. In further modifications, a single transmitting unit may energize all transducers 1, a separate transmitting transducer not associated with reflector 2 may be used, and overlap of the side-lobes of adjacent transducer beams may be reduced by appropriate shaping of the transducers 1 or reflector 2.

Filed: 1972-06-12
Abstract: 1382319 Inlaid wood veneer A D P PAYNE and J H PAYNE 5 June 1973 [12 June 1972] 27432/72 Heading B6G A wood veneer having a decorative inlay therein is produced by pressing an inlay of the desired design into one side of a wood veneer until the surface of the inlay is flush with the surface of the veneer, the other side of the veneer being supported during the pressing operation by a deformable support, and then removing the compressd projecting wood on the other side of the veneer. The projecting wood may be removed by grinding or sanding. Preferably the inlay has a bevelled profile and is inserted in the direction in which the bevelled profile tapers. The inlay may be made of metal, another wood, tortoiseshell and mother-of-pearl or a combination of such materials. Metal inlays are preferably formed by chemical or electrochemical milling or etching. Alternatively metal inlays may be formed by bending metal, such as copper or brass, wire into a desired pattern. The deformable support may be formed of rubber, bitumen-impregnated felt, or a rubber/canvas/ rubber laminate. In a modification of the method an assembly of a first deformable support, a first wood veneer, an inlay of the desired design, a second wood veneer and a second deformable support in which one or both of the facing surfaces of the veneers is coated with an adhesive is pressed so as to bond the two veneers firmly together, and compressed projecting wood on both surfaces of the laminate obtained is removed to expose the inlay. In this modified method the outer periphery of the inlay may be provided with an outwardly projecting double bevel which keys the inlay between the veneers or the inlay may be provided with a web of reduced thickness around its periphery. The inlay may comprise a series of inlay elements such as letters joined by a thin web of inlay material. This type of inlay may be made of a metal/ plastics film laminate, the inlay elements being formed out of the metal layer and the plastics film functioning as the web. In another modification as shown in Figs. 6A, 6B, and 6C, an assembly of a main veneer 18, a metal inlay 11 and a secondary veneer 23 is formed on a deformable support 12 between the platens 13 and 14 of a press. The main wood veneer is of slightly greater thickness than the desired final thickness of the product. Secondary veneer 23 is thinner than the main veneer 18 and is larger in plan than the inlay. The periphery of the secondary veneer 23 extends beyond the periphery of the inlay all round. The edge of the secondary veneer is feathered. Hydraulic pressure in the pressing operation may also be used.

Abstract: 651,447. Cutting cylindrical material. DUNLOP RUBBER CO., Ltd. Oct. 22, 1948, No. 27439. [Class 31 (i)] Apparatus for cutting lengths of tubular or rod-like material transversely into portions of pre-determined length comprises a guide member having a plurality of holes for guiding the said material, a cutting member adapted to traverse each of said guide holes in turn, means for trapping the material in the guide holes, means for releasing the material in a guide hole prior to the passage of a cutting member, means for advancing the material through the guide holes, and means for stopping each length of material in turn prior to the passage of the cutting member when it projects a pre-determined length through the guide hole. As shown, rubber tubing is fed by grooved rollers 2, 3, through holes 10 in a feed plate 9 to an assembly comprising a back guide plate 11 and a front guide plate 24. The material passes through holes 18, 25, in the guide plates and through holes 23, Fig. 6, in radial members 19, slidable in the front guide plate 11. Rotation of a cam 31 successively moves the slides 19 outwards, causing holes 23 to register successively with holes 18 and 25 and allowing the material to be fed through until arrested by a rotary stop 42, Fig. 1. The stop 42 is fixed to an arm 41 carried by a head 36 which is eccentrically mounted in bearings 38 and which also carries a disc knife 47 driven by pulley 49. The head 36 is driven by gears 39, 40, the engagement being such that as a slide 19 is operated by cam 31 and material is fed through the appropriate holes 10, 18 and 25, the stop 42 appears opposite the hole 25 to limit the length of material fed forward. The slide 19 is then released and grips the material again, the projecting portion of which is then cut off by the knife 47.

Title: Improvements relating to vacuum brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1919-11-07
Abstract: 157,601. Gresham, H. E., and Kiernan, G. Nov. 7, 1919. Testing; fluid-pressure.-To enable the brake cylinders of a vacuum brake system to be tested for leakage, a valve c normally held open by a spring g, Fig. 2, or by the vacuum in the system acting upon a diaphragm d, Fig. 1, is interposed between the train-pipe and the brake cylinder, which are connected respectively at a, b. In making a test, the valve is closed by a lever e to isolate the brake cylinder and the pressure gauge is watched to see whether such isolation results in an increase in the vacuum in the trainpipe. In case of a serious leakage, the valve can be held closed by a catch-piece f until a repair is effected. In the device shown in Fig 2. a valve h is seated to prevent leakage into the train-pipe, when the valve c is open.
