Title: Improvements in apparatus for producing images of cross-sections of solid bodies
Inventor: WALKER DAVID ARTHUR
IPC: G01N23/04
Filed: 1961-09-29
Abstract: 961,868. Radiography. ROLLS-ROYCE Ltd. Sept. 29, 1961, No. 35381/61. Heading H5B. Apparatus for producing an image of a selected cross-sectional plane of a body comprises a source of penetrating radiation, means for supporting the body so that the radiation passes obliquely through the selected plane to a fixed image-forming member responsive to said radiation, and means whereby the radiation source and the body may be rotated relative to the image-forming member, the rotations being about parallel axes and such that a line joining the source to a point on the imageforming member always passes through the same point in the selected plane. In the form shown, the image-forming member is a stationary film F. The body O under examination is supported on a turn-table T which can rotate about its own vertical axis (direction V). The radiation source S, which may be electromagnetic, radio-active, or ultrasonic, moves round the circular path Z. The turn-table T, in addition to rotating about its own axis with the same angular velocity as S but in the opposite sense, also moves bodily in a circular path Y at the same angular velocity as S. The disposition is such that the source S, the intersection of the selected plane C with its axis of rotation, and a fixed point on the film F, all lie on a straight line R. Thus, if a ray from source S passes through a certain point in plane C and falls on a corresponding point on film F, then, with the elements performing the motions described above, the same point on the film always receives radiation from source S through the same point in plane C. Therefore film F receives an image of plane C which is stationary relative to the film. This is only so for plane C. Other planes of body O above or below plane C will produce blurred images, giving a uniform background " fog " on which is superimposed the clear image of plane C. The height of turn-table T is adjustable so as to vary the position of plane C in the body.

Abstract: 1,159,707. Rotary positive-displacement pumps. BORG-WARNER CORP. Aug. 8, 1966 [Aug. 10, 1965], No.35405/66. Heading F1F. In a rotary positive-displacement pump of the externally-meshing gear-type, journals 36, 38, 50, 52, Fig. 1, for a pair of gears 24, 26 are supported by bearings 54, 56, 66, 68 that are loaded axially by the pressure of fluid in a chamber 81 acting upon a pair of axially-movable members 88, said chamber being connected to an outlet (30 Fig. 2 not shown), for the working fluid by a passage 100, and initial loading being effected by springs 98 in bores 92, which are connected to an inlet (28) for the working fluid by axial bores 91, recesses 108 in the members 88, axial bores 112 in the gears, a chamber 109 and passages 110, (114, 116) so as to facilitate escape of leakage fluid. The bearings are lubricated by the leakage fluid flowing along grooves 59 therein. The flow of leakage fluid may be regulated by a valve (not shown) in one or other of the passages (114, 116). The members 88 may be replaced by a single one (88b, Fig. 4, not shown), which abuts a common bearing unit (120) for the gears. The pump may be modified so that the pressure-loading members 122 are pressed against the bearings 66, 68 by the pressure of fluid in chambers 104, Fig. 5, containing springs 98C, these chambers being connected to the outlet (30) by passages 105. A chamber 132 associated with each of the members 122 is connected to the inlet (28) by way of a passage (130, Fig. 10, not shown), in the respective member and a recess 108C. The bearings 66, 68 are also pressure-loaded by leakage fluid in a chamber 102, which fluid enters this chamber from the highpressure side of the gears through a radial clearance space (101, Fig. 6, not shown), between the bearings and the housing 12. Pistons 123 on the members 122 may be either separate from or integral with said members. An annular lip on each of the members 122 may abut a sealing ring (138, Fig. 8, not shown), in the adjacent bearing. The springs 98C may be dispensed with, initial loading then being effected by springs (142, Fig. 11 not shown), abutting the portions of the members 122 of greatest diameter. Compensation for the pressure gradient across the gears may be obtained by either eccentric location of the annular lip on each of the members 122, Fig. 12 (not shown), or rendering the members 122 as a whole eccentric relative to the adjacent bearings.

Abstract: 1,055,679. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 18, 1965 [Aug. 20, 1964], No. 35430/65. Heading H4P. [Also in Division G4] A telegraph exchange having a number of incoming and outgoing repeaters comprises a computer which controls reading and writing of telegraph messages at a store. When a repeater receives a character to be passed to the store it emits a signal which, when the computer has completed its present operation. causes a cyclic counter to energize in turn logic circuitry associated with each repeater. When the relevant logic is energized, the counter stops. The logic output causes the computer store address selector to select at least two store locations associated with the repeater. The number stored in the first of these locations indicates the part of the store into which the received character is to be written: this number passes to an instruction register and also is increased by one and rewritten in the first store location. The received character now passes from the repeater to the relevant location in the store. The number in the second location indicates the number of free store locations for that repeater: this number has one subtracted and is rewritten in the second location. The computer main program can now be resumed. The operation for an outgoing character is substantially similar.

Abstract: 941,328. Hydraulic torque converters. J. M. VOITH G.m.b.H. Sept. 26, 1960 [Sept. 26, 1959], No. 35513/62. Divided out of 941,327. Heading F2C. An hydraulic torque converter comprises a guide wheel 9 which is arranged radially within the blading 3, 8 of the primary and secondary parts 2, 7 and has pivotal guide blades 11 disposed before the primary blading, with respect to the fluid flow, and substantially in the same axial region as the primary blading. The primary part 2 is secured to an input shaft 1 which is disposed within an output shaft 4 in the form of a sleeve carrying the secondary part 7. The guide wheel has the pivotal blades 11, which are controlled by a rod 10, adjacent to the entry to the primary blades 3 and fixed blades 12 adjacent to the exit from the secondary blades 8. The primary and secondary parts can be locked together by a friction clutch 13 and, when so locked, the blades 11 can be positioned so as to form a barrier between the guide wheel and primary part to reduce eddies between the rotating primary and secondary part and the stationary guide wheel. The symmetrical arrangement of the parts about a medial plane normal to the axis of the converter balances the axial effects of centrifugal force on the liquid in the converter.

Title: Improved method and apparatus for generating an artificial fog, smoke screen or like dispersion in air
IPC: A01G13/06
Filed: 1957-11-18
Abstract: 820,436. Fog-producing apparatus. ORCHARD DEVELOPMENT CO. (PROPRIETARY) Ltd. Nov. 18, 1957 [Nov. 20, 1956], No. 35804/57. Class 81 (1). In or for apparatus for producing an artificial fog, smoke screen or the like by the introduction into the exhaust manifold 1 or other region or area of the exhaust system of an internal-combustion engine 2, of a suitable heat-vaporizable liquid fuel or other vaporizable substance, in such a manner that said fuel or the like is vaporized and converted into smoke or fog which is projected from the exhaust conduit of said internal-combustion engine along with the exhaust gases, the provision of control means adapted to regulate the injection of the fog-producing fuel or the like, according to the heat generated at that point or region of the exhaust manifold or conduit to which the said fog-producing fuel or the like is introduced. As shown the fuel oil is delivered by a fuel valve unit 5 to the exhaust manifold 1 by the application of air under pressure to the fuel oil container 3, via the pipe 6, the valve unit 5 comprising a diaphragm valve controlled by a heat-sensitive device 7 connected to a tail piece comprising a heat exchange coil 8 by a conduit 10, which coil is attached to the end of the exhaust pipe 9 from the exhaust manifold 1. The air under pressure from the pipe 6 is led to the space above the fuel in the container 3 (Fig. 4) and to the space 17 above a flexible diaphragm 15 and is connected by small bore pipe 18 to the inside of the heat-sensitive device 7 which is actuated by a Bourdon tube 19 which in turn is operated by the heat exchange coil 8, the end of the pipe 18 being arranged to be closed by a spring-biased air bleed valve 20, mounted on one end of a pivoted valve lever 21, the pivot axis mounted on a pivoted bar 22 controlled by the manually adjustable eccentric stop 23. When air pressure is applied via the pipe 6 when the engine is stationary, or if running, before the minimum temperature has been reached, it acts equally on both sides of the diaphragm fuel valve 15, but owing to the extra pressure supplied by the spring 24, the fuel valve 15 will remain closed. As the temperature of the exhaust gases rises sufficiently to actuate the Bourdon tube 19, its movable end attached to a link 25 rises until a stop pin 26 on the link 25 makes contact with the underside of the valve lever 21, and by tripping it, opens the valve 20, resulting in the pressure in the chamber 17 falling sufficiently for the fuel valve 15 to be raised against the action of spring 24 by the air pressure in the container 3, so that the outlet passage 16 is opened to permit fuel to be forced up the outlet pipe 13, through the outlet passage 16 and pipe 4 to the exhaust manifold 1, where it is vaporized and discharged as a stream of smoke or fog particles from the exhaust pipe 9.

Abstract: 1,166,031. Depositing bacon slices &c. on to cards; sheet-feeding. CHEMETRON CORP. 10 Aug., 1966 [21 Oct., 1965], No. 35827/66. Headings B8C and B8R. Cards, particularly supporting inserts in a package of bacon, each with a tab or flap folded against them, are fed on to a conveyer, the tabs being opened during this feeding to enable the package contents e.g. bacon slices to be deposited on the cards. The tabs are then folded back over the slices. In one arrangement cards 11 with tabs 12 are fed between rollers 24 and 25 by a reciprocating pusher 32. Fingers 29, 30 of a guide plate 28 engage the cards' outer margins 15 and 16 so the card tends to bend away from the tab, the rollers then completely unfolding it before it is deposited on a conveyer 22. Bacon slices 31 are fed on to the card by a conveyer 20. In another embodiment for use where the tab extends to the card sides a guide (35), Figs. 5, 6 (not shown), directs the card leading edge to the rollers, but once through the rollers the leading edge connects with a switch (37) causing the guide to rise and so not deflect the tab, the rollers thus unfold the tab. Another modification incorporates a vacuum wheel (40), Fig. 9 (not shown), sited in advance of the feed rollers which grips the tab's upper surface and thus unfolding it before it passes between the rollers. The tab may be the same size as the card.
