Title: Improvements in or relating to apparatus for tomographic fluoroscopy in conjunction with image amplification
IPC: A61B6/02
Filed: 1954-11-11
Abstract: 769,463. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 11, 1954 [Nov. 14, 1953], No. 32712/54. Class 98(1) In X-ray apparatus for fluoroscopic tomography using an image amplifier, the image amplifier which follows the tomographic motion and an eyepiece which takes no part in the tomographic motion have ray deflecting means interposed between them which eliminate rotary motion of the image during the tomographic motion. The screen of the image intensifier is viewed through an eyepiece connected to the image intensifier by a telescopic tube containing movable prisms or the like for directing light to the eyepiece in all positions of the image intensifier. As shown in Fig. 2, a table 11 pivoted to a base 20 has an arm 14 pivoted at 13 to a lug 19 thereon. The arm 14 carries an X-ray tube 15 at one end, while the other end guides an image intensifier 4 under the table in a path such that the line 16 joining the focal spot of the X-ray tube and the centre of the input screen always passes through a point 7 collinear with pivot 13. The output screen is viewed through an eyepiece 9 mounted on the table 11 and connected to the image intensifier by a tube 10b and a telescopic tube 10a at right-angles thereto, the tube containing rotatable prisms to lead the light to the eyepiece. The layer of a patient or object on the table, which includes the point 7, may be raised or lowered with respect to the table by raising or lowering the pivot 13. The axis of tilt of the table may be movable along the table, and the eyepiece 9 and lug 19 may be coupled to move together longitudinally of the table. In a modification, the X-ray tube and the image intensifier move along circular or elliptical paths. As shown in Fig. 6, a body 34 to be examined is rotatable about an axis 33, 33a. Rays from a focal spot 1 pass through a section of the body and fall on the input screen of an image intensifier 4 mounted on a crank 48. The body 34 and crank 48 are connected together for rotation in synchronism. The output screen of the image intensifier is viewed by means of a telescopic tube 10a, 10b pivoted to a fixed block 41 and containing rotatable prisms which lead the light to an eyepiece 9. Specification 769,444 is referred to.

Title: Mirror reflex camera
IPC: G03B19/12
Filed: 1920-11-19
Abstract: 180,350. Steenbergen, J. Nov. 19, 1920. Cameras, reflex; shutters with sliding plates.-In a reflex camera the mirror is directly connected to and operated by a sliding member of the shutter. As shown a plate 27 is secured to the back of the mirror 28, and into the fork thus formed projects an horizontal extension 11 of a sliding plate 4 having an opening 26 which registers with the lens when an exposure is being made. Connected to the plate 4 by a spring 20 is a second sliding plate 19, which, during the exposure, follows the plate 4 to close the aperture 26, either immediately for an instantaneous exposure, or after a second operation of the shutter release for a time exposure. The mirror is moved to the finder position, or the shutter is set by depressing a handle extension 5 of the member 4, the parts being held against the pressure of a spring 12 by the engagement of a pin with the lower nose 3 of a right-angle lever 1 pivoted at 6. To make an instantaneous exposure the trigger 7 on the lever 1 is depressed, and the plate 4 is moved upwards by the spring 12, the plate 19 being momentarily held by a spring catch 17. This is tripped near the end of the movement of the plate 4 and the plate 19 is drawn upwards by the spring 20 to cover the lens. For a time exposure the nose 2 on the vertical arm of the lever 1 is moved by a bent plate 23 into the path of the handle 5, so that the upward movement of the plate 4 is stopped just short of the point at which the catch 17 is tripped. A second operation of the trigger 7 in the reverse direction frees the plate 4, which trips the catch 17 and allows the plate 19 to cover the lens. The catch 17 is tripped by contact with the bevelled end of a groove in the plate 4.

Title: Injection device for cyclic accelerators
IPC: H05H7/08
Filed: 1962-08-27
Abstract: 995,158. Particle accelerators. CESKOSLOVENSKA AKADEMIE VED. Aug. 27, 1962 [Aug. 25, 1961], No. 32757/62. Heading H1D. An injection device for a betatron comprises an electron gun 3 situated outside the region of the guiding magnetic field and a ferromagnetic injector tube 4 comprising one or more layers of anti-remanent ferromagnetic material extending tangentially towards and into the region of the field, magnetic saturation occurring just after the injection pulse has ended. The gun also is ferromagnetic material. Deflection plates 7 and 8 are provided for fine adjustment of the beam. To avoid distortion of the external magnetic field, the wall thickness, d, and permeability of the injector 4 are chosen to satisfy the condition: where D = internal diameter, Bo = magnetic induction due to the field and Bs = saturation value of the magnetic induction in the tube walls. Alternatively, deformation of the external field can be compensated by arranging current windings around the injector tube to give sinusoidal variation of current density in the azimuthal direction, or by interposing ferromagnetic strips between the injector tube and the guiding field magnet.

[Class 75 (i).] A hollow conical fuel jet discharged from a pressure atomizing nozzle 20 is impinged upon by two diametrically opposite air streams so that the fuel jet is flattened to become approximately elliptical in cross section. The air streams are discharged from passages 45 in a member 42 at the end of the air supply tube 15 communicating with a fan 17. The inlet ends of the passage 45 are approximately oval and the outlet ends 50 are approximately rectangular. The walls 51 converge to a line substantially ahead of the nozzle and the velocity of the air streams is somewhat greater than that of flame propagation so that the flame starts at a distance from the nozzle. The air streams, which are at a comparatively low pressure, supply all the air required for combustion. The angle of impingement of the air streams is preferably 90‹ but this angle may be varied and, by a suitable choice of atomizing nozzle, the flame may be made to fill a firebox. In the apparatus shown the fuel is supplied by a pump 23 on the fan shaft through an electromagnetically-operated valve 27 and a byepass valve 28, and is ignited by a gas pilot tube 25 projecting through a hole 44 in the member 42. Fig. 17 shows a suitable atomizing nozzle containing a double-threaded member 41 and a perforated plug 39.

Title: Improvements in knitting machines
IPC: D04B35/00
Filed: 1945-12-10
Abstract: 642,822. Knitting-machines. LINDSTORFF, W. Dec. 10, 1945, No. 33317. [Class 74 (ii)] A straight-bar machine is provided with cutting and clamping elements mounted in the sinker head to enable the yarns to be severed close to the article being knitted. Some of the elements are sinkers suitably modified to engage and sever the yarns being knitted and others may be sinker-like members disposed outside the needle row to sever a yarn withdrawn from operation. All of the elements, except the fixed member co-operating with the movable members for clamping the yarns, are operated by the catch-bar of the machine. As described in connection with a machine for producing stockings, a sinker 28 is positioned centrally within the needle row for severing the yarn of the last course of knitting of the toe of the stocking. This sinker has a recessed cutting edge 31 for severing the yarn and is adapted to be projected by the catch-bar 3 which through cams 14, 15 on the sinker head is raised sufficiently to become disengaged from the sinker 28 on its return movement. The yarn for the next course is then laid, being engaged in the recess 31. During the following movement of the catch-bar 3, the sinker 28 is again operated in the normal manner, its retraction causing the yarn. to be severed. Similar sinkers 24 are positioned at the ends of the needle row and serve to sever yarns, for example yarns introduced for reinforcing the material, in a similar manner. Outside the needle row a pair of fixed and movable clamping members 32, 37 are provided for each yarn guide 5 ... 8. The fixed members are provided with broad heads 33 between which the movable members 37 are projected by the catch-bar 3 to clamp the yarns. At the end of each row a cutter element 40, also operated by the catch bar, is positioned and is adapted to sever all of the yarns as the guides are introduced into and withdrawn from operation. To enable the various elements to be operated at the appropriate times they are provided with butts of different heights, the raising and lowering of the catch bar by cams 14, 15 facilitating selection as desired. In addition a movable latch replacing the front edge of the catch bar is provided for engaging the movable clamping elements 32.

Title: Improvements in and relating to semi-conductor devices
IPC: H01L29/00
Filed: 1963-08-23
Abstract: 1,065,092. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 23, 1963 [Aug. 27, 1962], No. 33467/63. Heading H1K. In the manufacture of a semi-conductor device a low resistivity and a high resistivity layer are epitaxially grown sequentially on a low resistivity substrate. The layers and substrate are of the same conductivity type and the process is such that any disturbed region arising from commencement of the growth of the first layer lies mainly within that layer and that no further disturbance is produced when the second layer is grown. In a typical case a wafer of 0À002 ohm. cm. P-type silicon or germanium is provided with P-type layers in this way, details of the epitaxial growth procedure being given. The resulting body may constitute the collector region of a transistor of which the emitter and base regions and contacts are formed by alloying two lead-antimony pellets to the second layer, and subsequently adding aluminium to the emitter pellet and realloying. Afterwards the wafer is soldered to a nickel strip using tin-gallium alloy, and electrolytically etched to mesa form. Emitter and base layers may alternatively be formed by epitaxy, or a diode formed by diffusing donor impurity into the second layer. The manufacture of P+PP+ avalanche injection diodes and photo-resistors from the body is also suggested. If desired, one or more of the epitaxially grown layers may be of a different basic semi-conductor material from the others or the substrate. In all cases the low resistivity epitaxial layer serves to isolate depletion layers of the device from the disturbed regions.

Abstract: 390,776. Controlling apparatus by light. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Prince, D. C. ; 150, Guernsey Road, Swarthmore, Pennsylvania, U.S.A.) Nov. 28, 1932, No. 33668. Convention date, Nov. 30, 1931. [Class 40 (v).] The temperature of a heated device which also emits light, e.g. an electric furnace, is controlled by directing the light alternately with a standard light, on to a light-sensitive device which operates control means for the heated device. A furnace 10 is heated by a resistor 11 connected through the coils 12, 13 of a saturable core reactor 14 to an alternating current supply 15, 16. The reactor is also provided with a coil 17 connected through transformer 37 to the anode 20 of a thermionic valve 18 preferably of the mercury vapour type. A battery 21 is connected through transformer 25 to the grid 19 so that normally it is sufficiently negative to prevent the passage of current. A light-sensitive device 22 is connected through a battery 23 and transformer 25. A mirror 29 driven by a synchronous motor 33 receives light alternately from the furnace and from a standard light 27 and directs it on to the device 22, each event occurring during one half of the cycle of the anode voltage of the valve 18. When the light emission of the furnace corresponds to the predetermined temperature, a reversal of the phase of the grid voltage with respect to the anode voltage occurs, the valve is rendered non-conducting, the saturation of the reactor 14 disappears, and current flow through the resistor 11 is prevented.
