Title: Improvements in and relating to Rotary Ultrasonic Testing Apparatus.
Inventor: HETHERINGTON MATTHEW JAMES
IPC: G01N29/26
Filed: 1966-08-24
Abstract: 1,199,414. Ultrasonic probes; ultrasonic inspection devices. STEWARTS & LLOYDS Ltd. 17 Aug., 1967 [24 Aug., 1966], No. 38061/66. Headings H4D and H4J. A rotary ultrasonic probe, employing liquid providing a path for ultrasound between one or more ultrasonic transducers 17 and a longitudinally moving steel tube or other article, comprises a pair of guideways of circular cross-section extending in opposite directions from at least one recess 10b which contains the one or more transducers 17. The recess 10b is of substantially smaller axial length than the guideways. In use, liquid leaks from the recess 10b and acts as a lubricant. Because of restriction of the rate of liquid leakage and the centrifugal force the recess 10b is kept full of liquid. Four piezo-electric crystal transducers 17 are preferably in an annular recess 10b. Two transducers may be used for shear wave detection of longitudinal flaws. One or two transducers may be used for shear wave detection of transverse flaws. One transducer may be used for continuous thickness monitoring. A base-plate 1 carries two end plates 2. A tubular stator 6 fits into a boss 7 in each end plate 2 and a stainless steel sleeve 8 fits into each stator 6. The sleeves 8 are selected to provide only a small clearance for tube under test. An insulating rotor 10 fits round the stators 6, an annular rib 10a, on the rotor 10 projecting radially inwards. The rib 10a is provided with the recess 10b. Holes 10c lead to the recess 10b and register with annular grooves 10d in the stators 6. Grooves 10d are connected to axial passages 10e for supply of water to the recess 10b. Further axial bores 10f feed water between the surfaces of the rotor 10 and stators 6 to lubricate bearing surfaces. Seals 12 seal support rings 13 on the rotor 10 to prevent leakage of the bearing water. A pulley 15 on the rotor 10 drives the rotor 10 by a belt 16. The transducers 17 are in removable holders 18 in radial bores 19 in the rotor 10 and are preferably less than 3/16 inch from the test surface. Electrical connections to the transducers 17 are through insulated slip rings 21 on the rotor 10 and are engaged by brushes 20 in holders 22 on supports 23. The brushes 20 are connected by wires (26), Fig. 3 (not shown) to connector sockets 25. A rotational speed of 5000 r.p.m. is permitted. Pulse repetition frequency of 50,000 pulses per sec. is possible. Three reflected pulses from defects as short as 6/100 inch can be obtained.

IPC: B24B7/22
Filed: 1960-11-07
Abstract: 972,693. Grinding and polishing. L. COLOMBI. Nov. 7, 1960 [Nov. 7, 1959], No. 38234/60. Heading B3D. A flat surface grinding and polishing machine comprises a polishing head with planetary arranged polishing and grinding tools 8, Figs. 1 and 2, having polishing surfaces rotating in their own plane and arranged perpendicular to a driving shaft, a carriage 5 raisably and depressably supporting the polishing head and adapted to run on carrying tracks movable in a direction transverse to the movement of the carriage, and a swinging transmission which co-operates with the driving shaft of the polishing head and imparts thereto additionally a circular swinging motion in a plane parallel to the surface of the grinding tools. A block L of stone to be ground and polished is placed on a bed 1 between supports 2, 3 along which is movable a span 4 supporting the movable carriage 5. The span and carriage are movable by rack-and-pinion gearing 24, 25, 31, 32, driven through reduction gearing and shafts 23, 30 from electric motors 16, 26. The carriage has a sector 47, Fig. 9, mounted on a pivot 48 and carrying a sleeve 52 supporting a shaft 56 which is rotatable by a pulley 57 connected by belts 58 to a motor 59 and at its lower end has a mount 60 for grinding and polishing wheels 89. The pulley 57 is also connected by a belt 62 to a reduction gear 64 mounted on the sector 47. The output shaft 65 of the reduction gear has an eccentric engaged with a rod 67 pivotally mounted to the carriage whereby the rotation of the shaft 56 is accompanied by an oscillating movement as a result of the movement of the sector about the pivot 48. The shaft 56 is axially adjustable to vary the height of the mount 60 by a hand wheel 79 which is lockable in position and operates a rack-andpinion mechanism 73, 75 to move a member 69 connected by bearings 70 to the shaft; a spring 74 between the rack and member 69 supplies a downward force to the latter to press the wheels 89 against the stone and to compensate for wear thereof. The mount 60 is formed with arcuate slots 61 which receive studs 85, Fig. 16, on a support 83 having shafts 86 carrying the grinding wheels 89. The shafts are provided with gears 92 engaging a toothed rim 93 which is rotatable relative to the mount and has wings 96 co-operable with resilient blocks 97 on the member 69 to prevent rotation of the toothed rim when the shaft 56 and support 83 are rotated whereby the grinding wheels rotate about their own axes and about the axis of the shaft 56 as the latter axis is oscillated. The shafts 23, 30 in the drive for the span and carriage from the motors 16, 26 have cams which operate switches controlling the motors so that, with switches actuated by adjustable blocks to control the extent of movement of the span and carriage, the grinding wheels can be moved to trace various paths over the surface of the stone.

Title: Electronic flashlight apparatus with automatic light control
IPC: G03B15/05
Filed: 1975-09-18
Abstract: 1480982 Electronic flash apparatus P METZ 18 Sept 1975 [28 Sept 1974] 38330/75 Heading G2X An electronic flash apparatus comprises a storage capacitor C1 dischargeable through a flash tube R÷l, with a series-connected thyristor Ty 1, and a quenching capacitor C2 for applying a blocking potential to the thyristor when a pre-set exposure is reached, a light-emitting diode D 1 being arranged in the charging path of the quenching capacitor. Both capacitors C1 and C2 are charged when a power source (not shown), is switched on. When the camera shutter is actuated, a synchronizing contact SK is closed and a pulse is applied from a triggering device Z to the gate of thyristor Ty 1 and also to the trigger electrode of the flash tube. This discharges capacitor C1 through the flash tube. Light reflected from the photographed object is measured by a light meter LM, and when a pre-set value has been registered (i.e. correct exposure), a pulse is applied by the meter to a second thyristor Ty2. This produces a negative voltage step on capacitor C2, which acts on thyristor Ty 1 to interrupt the discharge circuit. Capacitor C2 is now discharged by the current from capacitor Cl and is recharged in the original sense. Diode D1 lights up during this recharging process, so indicating that the meter LM has responded and operated thyristor Ty2. Some details of circuit modifications are given in Figs. 2-4 (not shown).

Title: Venoclysis apparatus
IPC: A61M5/14
Filed: 1961-10-26
Abstract: 933,536. Parenteral injection apparatus. ABBOTT LABORATORIES. Oct. 26, 1961 [Nov. 10, 1960], No. 38416/61. Class 81 (2). Parenteral liquid injection apparatus comprises two flexible liquid containers having their outlets connected through valve means located in the bottom of one of them and so arranged that the flow of liquid from one container prevents the flow from the other. The equipment is applicable to the injection of two solutions in sequence as from containers 51, 52, Fig. 1, in which no flow from container 51 can take place until the supply from container 52 is finished or interrupted by a tube clip 56. The supply tube 59 carries a perforating member 66, Fig. 7, which is passed through the wall of the container 51 into a U- shaped tubular member 55 having an outlet 65 for connection to the tube 57. It encloses a ball 71 which may be seated against either end aperture 70, 68 to close it. When a flow is received through the tubing 59 the greater hydrostatic head in the associated con - tainer 52, Fig. 1, causes the ball 71, Fig. 7, to close the port 70 to prevent passage of the contents of container 51 while the incoming liquid passes to tubing 57 and thence to the patient. When the flow from the first container ceases or is interrupted the liquid in container 51 forces the ball 71 against port 68, to prevent communication with the tube 59, and flows to the patient through tube 57. Other forms of valve device incorporating a float valve, a flap valve or a capillary passage are also described. In the latter case the passage extends between the two inlets and introduces sufficient resistance to flow to prevent communication as long as there is approximately the same head of liquid in the two containers. When the first container is empty, however, liquid flows through the passage from the second container to the patient.
