Filed: 1966-04-05
Abstract: 1,111,757. Cryosurgical instruments. S. P. AMOILS. 5 April, 1966 [13 April, 1965; 25 June, 1965], No. 15077/66. Heading A5R. A cryosurgical probe for eye or brain surgery or removal of tonsils, comprises a tube 5 closed at one end by a wall 6 of high thermal conductivity and enclosing a second tube 10 open at both ends, a cavity, formed by the closed end of the outer tube, and a restricting orifice 10A at the end of the inner tube through which gas under pressure, e.g. C0 2 , passes into the cavity to produce cooling by the Joule-Thompson effect, the construction being such that gas is freely exhausted from the cavity by the outer tube. Alternatively, gas may be supplied through the outer tube to the cavity via a restricted orifice, the inner tube exhausting gas from the cavity (Fig. 7, not shown). A stainless steel outer tube 5 having a silver end wall 6 is mounted in a silver ferrule 4 which is supported in a nylon handpiece 1. The rear end of the outer tube 5 communicates with an exhaust tube 12 and a flexible tube 13 which passes rearwardly out of the handpiece. A small-bore stainless steel inner tube 10 extends through the outer tube 5 and the exhaust tube 12 and is connected to an inner flexible tube coaxially arranged within the flexible tube 13. Carbon dioxide under pressure is supplied through the inner tube 10 from which it passes through the restricted terminal orifice 10A into the cavity defined by the forward end of the outer tube 5. The exhaust tube 12 has an opening 14, normally closed by an elastic sleeve 14B for venting the exhaust system if the pressure within it becomes excessive. A heating element 15 around the ferrule is accessible to gas being exhausted and a thermocouple is located on the inner side of the silver wall 6. Supply of gas to the device is controlled by a manual or foot switch (not shown) which operates a valve in a control unit (Figures 3, 4 and 5) to which the flexible tubes and electric leads are attached by a plug-and-socket connection (Figure 6). The heater alternatively may be located in the cavity (Figure 1A). The forward tip of the tube 5 is shaped according to its intended use. The operation of the heater is normally fixed and the desired adjustment in the cooling effect produced is effected by regulating the pressure of the gas reaching the restricted orifice by a valve in the control unit.

Title: Method of non-destructive eddy-current testing of electrically conductive tubes and corresponding apparatus
Inventor: DUFAYET JEAN-PIERRE
IPC: G01N27/90
Filed: 1969-03-24
Abstract: 1,255,064. Non-destructive testing of objects. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 24, 1969 [Oct. 19, 1968], No.15335/69. Heading G1N. In eddy current test apparatus for detecting defects (e.g. flaws, changes in dimension) in electrically conductive elements (e.g. non- ferromagnetic tubes and pins of nuclear fuel) each element 7 is passed through a coil 3 in a Hartley oscillator 1, the coil acting as a primary and secondary coil, an A. C. voltage generator 2, developing a voltage V, is connected to the coil, and a given type of defect is detected by means of changes in the grid voltage Vg of the triode 4 of the oscillator and/or the voltage V delivered to the oscillator as a function of the frequency of V. As shown, a sawtooth generator 10 causes the frequency of V to vary cyclically and continuously within a frequency band which extends on each side of the natural frequency of the oscillator and the changes in V g  and/or V as a function of the frequency are detected on an oscilloscope 12. The operator is then able to visually identify the types of defect from the respective curves. Alternatively the changes may be applied to a computer where they are compared with standard reference curves. In a further alternative, Fig. 5 (not shown), the changes may be applied to at least one gate whose opening is controlled by the sawtooth generator 10 so as to carry out in respect of at least one frequency the sampling of the voltage Vg and/or of the voltage V. When it is necessary to locate a given type of defect, a predetermined frequency is selected from a zene in which the sensitivity to this type of defect is as high as possible and to other types of defects is as low as possible and variations of V g  and/or V at this frequency are followed, e.g. on a recorder, Fig. 6 (not shown).

Title: Improvements in or relating to the heat treatment of metal objects in continuous heating furnaces
IPC: C21D9/56
Filed: 1954-05-26
Abstract: 787,844. Annealing. MUNKER, T. May 26, 1954 [May 27, 1953], No. 15514/54. Class 72 A continuous process for the heat treatment of metal objects comprises subjecting the objects to a high temperature for a short time in a suitable medium to dull or darken the surface, and then subjecting them to a conventional heat treatment. As shown, applied to the treatment of metal strip, the strip is wound off a coil 2 and passed through flames from gas burners 3 which produce a temperature of 1500‹C., the strip being in the flames for such a time as will cause a darkening of the surface and the temperature of the surfaces not exceeding 200‹C. The strip then passes through an electrically heated tunnel furnace G and is recoiled at 8. The temperature of the strip may be determined before it enters the hottest zone of the furnace by a pyrometer 11 which may be traversed across the furnace and which may be used to control the speed of the strip. In the case of separate objects passing through the furnace the pyrometer may be controlled by a light sensitive cell system 16, 17 to operate only when an object is in a predetermined position. Instead of gas burners there may be used a hot liquid which may have a chemical action on the surface or a high frequency electric heater may be used. The dulling of the surface may be further improved by mechanical means, e.g. by a roughened roller.

A clothes-washing machine having a container 11 for washing liquid and an impeller 13 therein, an emptying pump 18 of centrifugal or other non-positive type, common driving means 14 connected to both impeller and pump, and a lid 84 for the washing container, is characterized by a valve 58 in the delivery passage from the pump so constructed and . arranged as to interfere with and prevent the lid closing unless the valve is closed. As shown, there is also a spin-drier 12 with scavenging pump 44 both driven by motor 34, and a common outlet 59, 60 serves both washer and drier. Motor 14 drives impeller 13 and also via friction wheels 19, 20, the pump 18 to force wash-water from container 11 along outlet 51 past valve 58 when open with control 74 in the dotted line position, into junction 50 and out at 59 through hose 60 to waste. The valve is opened, the head 71 being raised from the seat 68 against the spring 73, by turning control 74 from the full line position through a right-angle into the dotted line position in which step 77 on casting 57 co-operates with face 78 on the control to maintain the valve open. Water from the spin-drier 24 enters the casing 22 whence it is forced by the pump 44 via outlet 49 and ball-valve 67 into the junctionbox 50 and out at 59, 60. The valve 67. also serves to prevent wash-water from entering the spin-drier outlet. The common outlet elbow 59 has an extension 80 slidable in a guide 79 and when in use is raised with its horizontal exit arm above the U-shaped guard 81, so that the elbow can be turned in any direction. The lid 84 cannot be closed on the machine until the control 74 is in its lower full-line position. Operation.-Hot wash-liquid and a load of clothes are put into container 11 and the impeller is run (with valve 58 closed) for a suitable period. The clothes are transferred to drier 12 and motor 34 started, the outlet hose 60 being directed into 11 for re-use. Meanwhile, a second batch may be washed in 11, the drier switched-off, clean rinsing water added to 24, the motor 34 again switched on and the rinsing water delivered to waste from hose 60. When washing is completed or fresh wash-water is required, valve 58 is opened so that pump 18 will empty the container 11. Specifications 612,737, 701,977 and 846,111 are referred to.
