Title: Ultrasonic inspection apparatus and method
Inventor: DEAN DAVID STANLEY
IPC: G01N29/12
Filed: 1965-03-31
Abstract: 1,131,075. Ultrasonic inspection devices. MINISTER OF TECHNOLOGY. 25 March, 1966 [31 March, 1965], No. 13674/65. Heading H4D. In an ultrasonic system for detecting discontinuities within a specimen by the transmission method the specimen is located between a receiving transducer and a focused transmitting transducer and is separated from the transmitting transducer in a gaseous medium. The arrangement permits inspection of a specimen subject to high temperatures. Both transducers may be focused to within the specimen and may be of similar type, or the receiving transducer may be coupled to the specimen by a liquid or may be a contact type as disclosed in Specification 1,118,141. Acoustic pulses with a carrier frequency at or near the natural vibration frequency of the transmitting transducer traverse the specimen and are detected by the receiving transducer, whose output is applied through a narrow-band amplifier to an analogue store (for subsequent analysis) and/or to a cathode-ray tube for display. The specimen is scanned by moving it relative to the transducers and electrical signals representative of the movement are passed, via the store, to the cathoderay tube to provide a plan position indication of discontinuities within the specimen.

Title: Improved corrosion resisting process and apparatus therefor
IPC: C23C22/76
Filed: 1937-05-21
Abstract: 501,430. Coating metals. GENERAL MOTORS CORPORATION. May 21, 1937 No. 14189. Void. Convention date, Mav 25, 1936. [Class 82 (ii)] Corrosion-resisting coatings are formed on the surfaces of metal articles by supporting the articles in the air and washing the surfaces continuously with rust-proofing solution under high pressure so that the reaction products are continuously removed from the surfaces. The rust-proofing solution may be, for example, a solution containing chromic acid and a halide, a solution containing one or more of the dihydrogen phosphates of zinc, iron, and manganese, and a nitrate such as copper or sodium nitrate, or a solution containing zinc dihydrogen phosphate and nitrous acid or a nitrite, but any solution which will form a rust-proof coating on metals such as iron, zinc, magnesium, or aluminium may be used. The spraying pressure may be as high as 20 lb. per square inch. In the apparatus shown, the articles 6 are carried, by means of trolleys 10 running on rails 9, through a chamber 5 having end walls and partitions 8 which hinder escape of the treating liquid but are shaped to allow the articles to pass. The rust-proofing solution is sprayed substantially at right-angles on to all the surfaces of the articles from outlets in pipes 14 and connecting pipes 15 which are supplied by a pump 18 which draws solution from a reservoir 20 through a filter 22. Universally adjustable nozzles are preferably provided on the pipes 14 and 15 so that the direction of the jets can be controlled, and heating coils 24 are provided in the reservoir 20. Shields 13 protect the means supporting the articles from the action of the solution. The articles are preferably washed immediately after the rustproofing treatment.

Filed: 1963-04-09
Abstract: 1,010,920. Retractable undercarriages. RECHERCHES ETUDES PRODUCTEN R.E.P. April 9, 1963 [Jan. 18, 1963; April 4, 1963], No. 14230/63. Heading B7G. An aircraft undercarriage leg has a cylinder T (Fig. 1) on which wheels are mounted and which is partially retracted within a casing J during undercarriage retraction by a rod 3 pivoted to a crank 4. In the embodiment shown in Figs. 1 and 3, the undercarriage is retracted by extending a jack 21 thus putting a bar 16 in tension and rotating the casing J about a pivot 1. The bar 16 is connected to a shaft 15 mounted on the easing, so that as the casing rotates, a lever 13 rotates relative to it, as does a lever 10 in the direction f1 (Fig. 3), rotating the crank 4 in the same direction and withdrawing the cylinder T into the casing. The lever end of the rod 3 is connected to a piston 2 about which the cylinder T may slide when the aircraft is on the ground. In a modification (Figs. 8 and 9), the undercarriage is raised by shortening the jack 21 and the rotation of the bar 16 relative to the casing is transmitted through a member 16a pivoted at 15 to the lever 13. The upper end of the shaft is pressed against an abutment B in the down position with a force which can be varied by adjusting the relative positions of the bar 16 and the member 16a.

Abstract: 528,861. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. May 12, 1939, No. 14239. Convention date, June 11, 1938. [Class 40 (v)] In order to prevent confusion due to reflected or refracted signals forming spurious course-lines, a navigational run-way XY is defined by two sharplydirected overlapping beams A, N, A<SP>1</SP>, N<SP>1</SP> confined to the limited angular zones 11, 14 and 15, 18, and navigational signals are provided outside these zones by less sharply-directed lobes P, Q. The true course is unaffected by any reflecting object, such as 20, outside the angular zones, although navigational signals can still be received outside these zones. Preferably the course-line is marked by complementary A-N signals, and each of the sharplydirected beams is produced by two V aerials radiating 3-metre waves modulated at 500 c.p.s., the aerials producing the beams A, A<SP>1</SP> being energized simultaneously with those producing the beams N, N<SP>1</SP>, so that the same keying signal is heard irrespective of the direction of approach. The figure-of-eight field P, Q is produced by a central energized aerial and two lateral keyed reflectors which produce only a small field-strength along the course-line. The same wavelength is used as for the beams but modulated at 2,000 c.p.s., the lobes P, Q being keyed by A-N signals which are not quite complementary so as not to produce another continuous dash on the course line ; alternatively two separate arrays may be employed to produce the lobes P, Q. The beams and lobes may be distinguished by the use of different carrier frequencies or keying signals.

Abstract: 1431537 Residual chlorine measurement NEW COSMOS ELECTRIC CO Ltd 1 April 1974 [31 March 1973 4 June 1973 24 Aug 1973] 14329/74 Heading G1N Apparatus for measuring residual chlorine (both free and combined) in water comprises a container 1 having walls through which the water level is visible, an electrically insulating pivotally movable rod 2 in the container and having an electrode (Pt) of a carbon or a metal nobler than silver on its unpivoted end, second and third electrodes (Ag, Cu) of silver and copper arranged to be immersed in the water, means for driving the rod so that it generates a cone with apex at the pivot 3 and an ammeter for indicating the current flowing between the first and either the second or third electrode. The copper and silver electrodes may bemounted on rod 2 or on the container walls. A hole 12 is provided for filling the container to a desired level marked by graduators 31 and a thermometer 4 for water temperature is provided. The rod is pivoted by eccentric 11. The measuring circuit has a variable resistor VR 3  which is set to a value determined from thermometer 4 by pointer 8 or scale 19 for temperature compensation. Variable resistors VR1, VR2 provide range adjustment for measurement with the copper electrode (switch positions T1 and T2) and the silver electrode (positions F1, F2) respectively. Determinations of total chloride. The water in the apparatus is acetate buffered to pH4 and K1 solution is added. The current between the Pt and Cu electrode is proportional to total Cl. Determination of free chloride. The water is acetate buffered to pH 5 and the current between the Pt and Ag electrode is measured. Titration method. The apparatus may contain a syringe for injecting standard volumes of phenyl oresonoxide coupled to a counter for measuring the number of injections. For free chlorine determination, the solution is phosphate buffered to pH7 and injections are made until the ammeter registers no change on injection. For total chlorine acetate buffer to pH4 and K1 are added before injections. The pivoted rod is oscillated during all measurements so that the concentration slope adjacent the electrode is controlled. The electrodes may be surface treated before use, to improve linearity of response. The platinum electrode may be ground with glass grains in carboxylic acid e.g. tartaric acid solution. The silver electrode may be treated with chloride ions to form a coating of silver chloride which is photochemically reduced to silver. Gold or carbon electrodes may replace the platinum but the carbon is easily polluted.

Filed: 1945-06-07
Abstract: 597,829. Automatic control systems. FOSTER INSTRUMENT CO., Ltd., and OUGHTON, H. G. June 7, 1945, No. 14389. [Class 38 (iv)] A variable, e.g. temperature, is controlled by a device, e.g. motor 6, which has a normal position to which it returns after effecting correction of the variable, the normal position being moved by a device, e.g. a motor 7, in the direction of movement of the motor 6, but having no influence on the motor 6 until it returns to its new normal position. A stylus 1, Fig. 1, moving in accordance with the temperature of a furnace is intermittently depressed by a bar 2 to close contacts 3, 4, 5 or 28 according as the temperature is the desired normal, below the normal, above the normal or very much below the normal, and thus energize solenoids 8g, 9g or 8h, or 9h or 29 respectively to actuate switch arms 8a, 8b, 9a, 9b. In the position shown in Fig. 2, the stylus 1 has closed contacts 4 to energize solenoid 8h. Contacts 8a, 8c, Fig. 2, have closed to energize winding 6b of motor 6 to increase the fuel supply to the furnace; motor 6 also rotates a drum having conducting segments 10c, 10b separated by a non-conducting segment 11. Solenoid 8h also closes contacts 8b, 8c, to energize winding 7b of motor 7 over an interrupter 15 so that motor 7 slowly moves a sliding contact 12 towards the segment 10b of the drum. When stylus 1 ceases to close contacts 4 and closes contacts 3, solenoids 8g, 9g are energized to break contacts 8a, 8c and 8b, 8e, thus de-energizing windings 6b and 7b, and to make contacts 8e, 8d to complete a circuit for winding 6c over the contact 11 and segment 10c; motor 7 thus stops, but motor 6 reverses until contact 12 is over the non-conducting segment 11 so that the normal fuel supply has been increased compared to what it was before actuation of contacts 4. Solenoid 8g also closes contacts 8b, 8f to energize a slow-acting relay 25 to open contact 14 and prevent subsequent operation of the motor due to momentary variations of temperature. The motor 7 may be similarly controlled. A corresponding sequence of operations follows closure of contacts 5. In both motor circuits, limit switches 16, 21, 23, 24 open contacts 13, 17, 19, 20 when the valve is at its maximum or minimum value. In a modification, Fig. 3 (not shown), the winding 6b is energized only through the drum, the relay 25 is eliminated, and a further relay controls contacts in the circuit of winding 7b so that it is not energized when the limit switch 17 is open.
