Title: Defect detection
IPC: G01N29/24
Filed: 1971-03-18
Abstract: 1397065 Ultrasonic probes; ultrasonic inspection devices BRITISH STEEL CORP 9 June 1972 [18 March 1971] 7198/71 Headings H4J and H4D In coupling a moving strip or sheet 4 (Fig. 1) with an ultrasonic transducer arrangement 1, a member 8 movable relative to a housing 3 is resiliently urged into contact with the strip or sheet 4 and coupling liquid is fed through a nozzle 16 and into passageways 15, 14 to flood the region between the transducer arrangement 1 and strip or sheet 4. The housing 3 comprises a cylindrical outer easing 5. Screws 6 secure an annular support 7 to which in use a detector 2 is attached. Member 8 is annular, is slidably mounted within outer casing 5 and is resiliently urged by three adjustable springs 9 away from annular support 7. Member 8 has a cylindrical extension 11. Support 7 has a cylindrical extension 12. The two extensions 11 and 12 are joined by a flexible tube 13 to define an inner chamber for the transducer arrangement 1 and detector 2. In use, this inner chamber is filled with water or other liquid which surrounds the transducer arrangement 1 and provides the acoustic coupling. The liquid is pumped through the nozzle 16 and passes through an opening 17 via an outlet elbow 18. The liquid may be recirculated by the pump or may merely pass out of the elbow 18. The device may utilize two transducers 22 (Fig. 2) of radius 10 mm. and three transducers 23 of radius 6 mm. They may cover an area of width 25 mm., each being coupled to a separate amplifier, all amplifiers having the same gain. Transducers 23 produce a defect signal when covered by a defect whose greatest dimension is 3 mm. whereas the same signal will be produced by transducers 22 only for a defect whose greatest dimension is at least 5 mm. Thus the transducers 23 are more sensitive than transducers 22 and may be used to test the edge of a strip or sheet where small defects are important, e.g. if a strip is to be welded at the edge.

Abstract: 869,194. Photo-electric measuring instruments. PERKIN-ELMER CORPORATION. March 2, 1959 [March 4, 1958], No. 7221/59. Class 40(3) [Also in Group XX] In a double beam spectrophotometer the reference and sample beams are alternately passed to the entrance slit of a Littrow type monochromator along a common path and the beam size is limited by an aperture stop or stops situated at the optical conjugate of the Littrow mirror of the monochromator. Infra-red radiation from a source S may, as shown, be directed by toroidal mirrors 11, 12 to form co-planar images 13 of the source, after passing through a sample and a reference substance. Plane mirrors 16, 17 and 18 direct the two beams to a crossing point where there is a rotary chopper 19 to ensure that equal portions of the sample and reference beams are directed along the common path towards mirrors 20, 24 and 25 of which the mirror 20 is toroidal and forms a further image of the source at the entrance slit 23 of Littrow type monochromator 22. The aperture stop 21 in the common beam path is imaged by toroidal mirror 20 and paraboloidal collimator 26 on the Littrow mirror 28 and so determines the beam size incident on this mirror and on the dispersing element 27. Entrance slit 23 is also imaged on the exit slit 29, an image of which is formed on infra-red detector 31 (e.g. a thrmo couple) by ellipsoidal mirror 30. In a modification, two optically coincident aperture stops are used, one in the path of each beam before it reaches the crossing point.

Abstract: 576,921. Refrigerating. PRESSED STEEL CO., Ltd., NOLCKEN. W. G., and BRANDON, A. O'B. April 22, 1944, No. 7492. [Class 29] [Also in Group III] In refrigerating apparatus of the vapourcompression type using refrigerants in which the lubricating oil is soluble, an auxiliary condenser 13 is arranged between the compressor 11 and the oil separator 14, in which refrigerant vapour is caused to condense upon the oil droplets being carried by the refrigerant vapour, the oil and condensed refrigerant being thereafter separated from the vapour and heated in the oil separator without ebullition to re-evaporate the condensed refrigerant from the oil. Compressed refrigerant from the compressor 11 passes through a coil 12 to the auxiliary condenser 13 where the refrigerant vapour condenses upon the oil being carried as mist, and the drops so formed are separated from the vapour by gauze 19 in the oil separator 14. The oil-refrigerant mixture collects upon a tray 23 whence it trickles down a wick 20 surrounded by the coil 12 heated by the passage of the refrigerant vapour from the compressor so that refrigerant vapour is evaporated from the mixture without ebullition. The oil is collected in a space 21 from which it is returned to the compressor crankcase by a float-operated needle valve 22. The oil-free vapour from the top of the oil separator 14 passes to the condenser 15, liquid receiver 16, expansion valve 17 and evaporator 18 back to the compressor. The coil 12 may be replaced by an electric plate heater and the auxiliary condenser 13 may be water-cooled.

Abstract: 1420016 Measuring thickness photo-electrically E I DU PONT DE NEMOURS & CO 15 Feb 1973 7533/73 Heading G1A In measuring the thickness of material O by interrupting a laser beam of parallel light rays, the beam is divided into discrete portions and the number of such portions reaching a photo-detector P is counted at C. As shown, a light beam from a continuous wave helium-neon laser L S  is expanded in the vertical direction by cylindrical lenses L 1 , L2 to a width D which is sufficient to cover the range of movement of the material O, which may be unsupported elastomeric gasket material in a smoke filled curing oven. A grating G having equal thickness transparent and opaque horizontal regions splits the light beam into portions, which are focused by L3 on to an oscillating mirror M which reflects them sequentially via L4 and slits to a silicon photovoltaic diode photo-detector P. The total count for 100 oscillations of the mirror is recorded at C. The counter C may count up from zero or down from a value representing D. Alternatives. Instead of the grating G, the light source may be pulsed, e.g. by modulating the laser discharge or by a kerr cell, rotating polarizer or chopper wheel. Instead of lenses L3 and L4 and mirror M the photo-detector may scan the light coming through the grating G. A linear array of photo-detectors may be used instead of the grating and be interrogated sequentially to get the count or their outputs could be simultaneously decoded by a matrix. The counter C may give audible or visible indication and a continuous record may be made. If the material O can be supported on a reference surface, the width of the beam D need only be enough to cover the range of possible thickness variations.

COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 21 Feb 1972 [19 Feb 1971] 7884/72 Heading H4P A T.D.M. transmitter has a parallel/aerial converter the output being synchronized with clock pulses and a bit added for parity checking. At the receiver the input is decoded and a counter checks the number of data bits received in a cycle, the first items being separated and the remainder are routed to groups of stores identified by the first items. The counter is re-set on reception of an incomplete number. A buffer store MT, when containing data gives a cyclic initiating instruction DC to PO giving in turn an output E1 to bi-stable BB thus initiating clock HL to give periodic pulses, e.g. of 2 Ás to counting element C1 comprising cascaded bistables, which define its state at any step in binary code on outputs A-D and which are presented simultaneously to multiplexers MX1- MXi. Inputs Eo-Em of MX1 &c. receive n data items received from peripheral facilities sent cyclically by a central station of which buffer MT forms part. All multiplexers MX1 &c. present simultaneously to common multiplexer MX outputs corresponding to the instantaneous count in C1. A single data item emitted by MX is dependent on the output F, G by second counting element C2 which extends the range of C1. If the total number of data items is less than the counting capacity of CE an output from parity bi-stable BP1 is inserted into input Ek and transmitted to the receiver, this being a 0 or 1 in dependence of whether the 1 state data items are even or odd. At the receiver R decoder DI separate data from clock signals, the latter being passed through a mono-stable delay B1M and passed to counter CR and input H of register RI each clock pulse received therein enabling it to record a data item from DI. At the third clock pulse, counter CR causes NAND element PE1 to close and thus inhibit further entry of data into RI.
