Title: Using neutron beams for a microscope for cancer research or  for cancer surgery
IPC: G21K7/00
Filed: 1974-10-29
Abstract: 1447848 Apparatus for emitting neutron beams A P PEDRICK 29 Oct 1974 46890/74 Heading G6P [Also in Division H5] Apparatus comprises material made radioactive by containment in a nuclear reactor, surrounded by a shield (e.g. lead) which emits a concentrated beam of neutrons through a duct and has means beyond the duct for interrupting all but the fastest neutrons, which have a wavelength of about 10<SP>-13</SP> cm., the neutrons, it is asserted, being of the form comprising a proton core surrounded by a meson cloud both of which consisting of very large numbers of miniscule particles, i.e. true atom or graviton particles the interaction between which taking place as a result of simple gravitational forces. Fig. 15 shows a microscope, the source being a sub-critical mass of uranium 235 or thorium; electromagnets 3 set up an oscillating magnetic field to deflect the slower moving neutrons from a central hole in a plate 4. The resulting beam is further deflected by electromagnets 6 to scan the internal structure of a living cell at 7. A base 8 of a vacuum tube below the cells is coated with material responsive to neutron bombardment; a lens 9 and mirror 10 provide a magnified image of the cell. The intensity of the beam is not great enough to affect the tissue of the cell. The base 8 may be in the form of a moving film, the beam being interrupted periodically to enable a series of photographs to be obtained. Fig. 16 shows a beam of neutrons passing through a series of discs 17, with single holes, rotated at high speed by electric motors 13, so that for a given speed of rotation only neutrons of a particular speed, i.e. the fastest, would be able to pass through all of the holes. Here, the beam is used for cancer surgery.

Abstract: 1470970 Spray carburetters; screw pumps LUCAS ELECTRICAL Ltd 12 Aug 1974 [9 Oct 1973]  47065/73 Headings F1C and F1H [Also in Division G3] The flow of fuel from the carburetter float chamber 16 to the fuel metering needle valve 13 is regulated by varying the effect of a pump 17 between the chamber and valve to minimise the exhaust pollution by an engine supplied by the carburetter. In the embodiment shown signals from an inlet manifold pressure sensor 22 and an exhaust composition sensor 23 are received by a unit 21 which controls the speed and direction of rotation of an electric motor 19 driving the pump impeller 18. The sensor 22 sets a varying limit to the output of the unit 21 so that the control which can be effected by the sensor 23 is approximately proportional to the mean flow of fuel required by the engine. The unit 21 may receive engine speed and throttle valve angle signals. The impeller may be magnetically coupled to the motor and a gear box may be provided therebetween. The impeller may constitute the rotor of an induction motor. The pump may be a variable stroke pump or the effect of the pump may be controlled by a variable restriction pump by-pass. The impeller may have tapered helices of opposite hand at opposite ends co-operating with corresponding bores so that axial impeller displacement regulates the fuel flow. The unit 21 may receive an input dependent upon engine temperature to increase the mixture richness at engine cold starting.

Title: Construction and anchor therefor
IPC: E04F13/08
Filed: 1977-11-17
Abstract: The load-bearing anchor (110) is used for suspending wall-cladding panels (131, 132) on, and in front of, a load-bearing structural part (121). The load-bearing anchor (110) is fitted fixedly in the load-bearing structural part (121). The wall-cladding panels are connected at its (110) end directed away from the load-bearing structural part (121). It (110) has an upper chord (111) and a lower chord (112). The chords (111, 112) are connected to each other at that end of the anchor (110) directed away from the load-bearing structural part (121), and the other ends of said chords are fitted in the load-bearing structural part (121) at a distance from each other. The result is a framework, in which the clamped-in chords (111, 112) and a flexurally rigid configuration of the joints in the region of the connection of the two chords have a favourable effect on the cross-sectional dimension of the load-bearing anchor (110). <IMAGE>

Abstract: 1,263,770. Fluid cushion load pallet. AEROGO Inc. 30 Sept., 1969 [30 Sept., 1968], No. 48000/69. Heading B7K. A fluid cushion load pallet 1 comprises a rigid backing member 4, upper and lower annular flexible wall portions 19, 21, Fig. 4, forming a hollow annular body inflatable to form a torus 17, a part of wall 19 being fluid-tightly sealed at 20 to the member 4 so that a plenum chamber is formed, and means for inflating the body and pressurizing the plenum chamber including a fluid supply inlet 40. Attached to member 4 are central and corner landing pads 12, 14. The inner and outer edges 23, 26 of walls 19, 21 are fluid-tightly sealed by perimeter binding tapes 23, 28, and wall 19 is provided with an inlet aperture 42 and surge outlet apertures 44. Initially, with torus 17 deflated, pressurized fluid from inlet 40 enters the body via aperture 42, whereupon the body assumes a rounded shape and the fluid from inlet 40 maintains pressure: in the plenum chamber and the torus chamber 31. Pressure build-up breaks the bearing seal between sheet 21 and the ground surface 16, and a perimetrical throttling gap 48 is established. Unbalanced loads or uneven surfaces effect rapid pressure equalization via surge outlets 44, thus ensuring stability of operation. In an alternative embodiment, Fig. 6 (not shown), the upper wall portion is formed by a pair of flexible sheets having overlapping edges. clamped to the backing member. The skirt is made of a laminated multi-ply non-porous material having the warp of adjacent plies positioned at an angle from one another, and it is stated that this increases the dimensional stability and makes more uniform any distortion in the torus.

Depression of a key 189 brings a lower end of a key stem 181 thereof into stopping relation with an arm 251, Fig. 5, on a gear 247 coupled to the print wheel 265. The arm 251 is oscillated during a machine cycle by oscillation of a bail 279 permitting counterclockwise rotation of a gear 259 under bias of a spring 267 and later returning the gear clockwise. The platen 325 is driven for impression by toggle linkages 315, 317 and 319, 321. Interlocks; locking devices.-A spring biased bar 199 serves as a detenting interlock for each key bank, and may be locked to prevent cancellation of a key depression by a key stem 241 formed with a projection 243 capable of preventing movement of bar 199, and a notch 245 for engaging the machine cover to hold the key in depressed position. The key banks set up for character printing are normally cancelled after a printing operation by a flexible clearing member 217 which engages fingers 215 on the bars 199; however this can be prevented by depression of a repeat key (29, Fig. 1, not shown) whereby a bail 231, Fig. 4, is pivoted to block movement of the fingers 215. In the absence of a document to be printed on, depression of the motor bar (33, Figs. 1, 2, not shown) is blocked by a projection (389, Fig. 14, not shown) on a document detector lever (381). Paper shields; hammer constructions.-The platen 325, Fig. 10, is formed with a resilient surface 397 for impacting the print wheels 265, Fig. 5, and steel faces 344 for engaging the surfaces of print wheel support members 301, 303 to limit the depth of impression. Screws 343 are provided to adjust the platen 325. Aligning for impression.-During a machine cycle, the print wheels are aligned and locked in selected position in two stages. A cam 283, Fig. 5, rotating with bail 279, engages an aligning member (287, Figs. 6 to 8, not shown), firstly engaging a rod (291, Figs. 6, 8) with gear teeth on an idler gear 263, Fig. 5, and secondly engaging a plate (297, Fig. 7) between type characters on the print wheels 265.
