Title: Improvements in or relating to methods of testing materials for flaws and apparatus therefor utilizing ultrasonic waves
IPC: G01N29/06
Filed: 1952-03-16
Abstract: 696,920. Ultrasonic inspection devices. GLASS DEVELOPMENTS, Ltd., and SPROULE, D. O. March 7, 1952 [March 16, 1951]. No. 6359/51. Drawings to Specification. Class 118 (ii). In a pulse-echo ultrasonic testing system, a two dimensional display of defects is produced by moving a transmitting and receiving piezo-electric crystal transducer unit over the surface of the test sample or by rotating a directional transducer unit on the surface thereof, the echo signals being applied to intensity modulate a cathode-ray tube whose time base is synchronised with the pulse transmission and the time base being displaced or rotated in correspondence with the movement of the transducer. Alternatively the time base is maintained stationary and photographed, the film or camera being displaced or rotated in correspondence with the transducer movement. The transducer unit may comprise separate transmitting and receiving transducers mounted as a single unit, Fig. 1 (not shown). The following combinations of movements are described: (1) rectilinear movement of transducer unit and of time base or camera, Figs. 1 and 2 (not shown), (2) rotation of transducer unit and of time base of camera, Figs. 3 and 4 (not shown), giving a radar P.P.I. type display and (3) rotation of transducer unit and rectilinear displacement of time base or camera. Figs. 5 and 6 (not shown), giving a radar B type display. In system (1) the ultrasonic beam is transmitted perpendicularly to the surface of the test sample but in systems (2) and (3) a beam Rayleigh (i.e. surface) waves is directed along the surface when searching for surface defects, e.g. cracks, and a beam of longitudinal or transverse waves making a small angle with the surface of the test piece is employed when detecting flaws in sheet metal. Since the intensity of the echo depends upon the angle of incidence of the impinging beam, the transducer unit in systems (2) and (3) may be moved along an arc of a circle with the suspected flaw as centre.

Title: Improved process of and apparatus for making or finishing the necks of glass containers
IPC: C03B9/325
Filed: 1920-03-04
Abstract: 152,569. Wade, H., (Lockwood, L. V.). March 4, 1920. Pressing.-Relates to a machine for making the necks of carboys and large glass containers having internally-screwed mouths and consists in forming the mouth by pressing a charge of metal on to the hot neck of the carboy immediately after it is removed from the mould. The machine comprises a table A, Figs. 1 and 2, on which is mounted a neck mould B consisting of a lower section 2, which is firmly secured to the table, and two upper sections 3 which are hinged to the section 2 and can be opened and closed by a sliding rod 6 operated by a pedal. The upper sections 3 are formed with a rectangular cavity adapted to hold a charge of metal. A pressing- plunger 24, which fits snugly into the cavity in the mould sections, is operated by a fiuid-pressure cylinder 25 which can be moved backwards and forwards along guide-bars 30 by means of a hand-lever 36a. The plunger 12 that forms the inside of the mouth of the carboy is attached to a mandrel C which can be moved backwards and forwards by a crosshead 7 carried by the pistonrods 7<a> of a pair of compressed air cylinders C<1>. On its forward movement, the crosshead 7 presses against a collar 16, Fig. 7, that slides on and is connected to the mandrel C by a spring 17. The collar 16 has cam-slots 16<b> which operate levers 14 pivoted in slots in the plunger 12. The front ends of these levers 14 are formed with thread segments which form interrupted screws 15<b>, Fig. 6, on the inside of the bottle neck. At a certain point in its forward movement, the mandrel C is held by a stop 11 and further movement of the cross-head 7 slides the collar 16 forward so as to separate the threaded ends of the levers 14. On the reverse movement of the cross-head, the spring 17 moves the collar 16 so as to close the threaded ends of the levers 14. The cross-head then strikes a stop 21 on the mandrel and thus withdraws the plunger 12 from the mould. An annular air-pipe E perforated in its inner side supplies air jets to cool the plunger 12. In use, the mould is closed, the plunger mechanism moved into the position shown in dotted lines in Fig. 1, and the cylinders C<1> operated to move the plunger 12 into the moulds. A carboy F is removed from the mould in which it is blown, and has its neck inserted, while still hot, into the mould as shown. A charge of metal is then dropped into the mould cavity, and the plunger-mechanism is moved into the position shown in full lines, the moulds being locked by means of cams D<3> and a weight D<4>. The plungermechanism is then operated to press the metal in the mould, the lower side of the plunger being shaped to conform to the neck space in the mould. If there should be an excess of metal, the carboy is forced slightly away from the mould. Specification 151,588 is referred to.
