Abstract: 1532243 Stop motion for a filament supply package; knitting machines D A JAMES 30 Sept 1976 [9 Oct 1975] 41352/75 Headings D1C DID D1E D1F D1J and D1M To ensure that when a yarn package is being unwound the unwinding operation shall cease while there are still some yarn turns on the package, a radiation source and a radiation sensor are so arranged with respect to a yarn carrier that is transmissive or emissive of radiation that when sufficient yarn turns have been removed the radiation detector is able to receive radiation via said carrier and so stop the unwinding operation. The yarn carrier may be perforated with a radiation detector inside the carrier and a radiation source outside the carrier, or vice versa. The radiation source may be a lamp. When sufficient turns have been unwound the radiation is able to pass through said perforations from the source to the detector. Alternatively the detector is outside the carrier, and the carrier is provided with a radiation source. When sufficient turns have been unwound the detector is able to detect the radiation and stop the unwinding operation. The stop motion is suitable for use in knitting and weaving machines.

Title: Nuclear reactor with emergency coolant cross flow
IPC: G21C15/18
Filed: 1965-10-01
Abstract: 1,067,909. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 1, 1965 [March 29, 1965], No. 41859/65. Heading G6C. In a liquid sodium-cooled fast reactor, during an emergency causing a rapid rise in the reactivity of one fuel element, changes in the coolant flow in the element are automatically effected by the rise in pressure so as to transfer heat into surrounding coolant and moderator, thereby absorbing thermal shock. Coolant urged from the fuel element is deflected so as to protect the reactor vessel. Reactor control is effected by vertical movement of reflectors mounted externally of the reactor vessel. Each fuel element is formed of a hexagonal shroud tube containing a central moderator rod and a surrounding hexagonal array of fuel rods. Coolant normally flows vertically upwards through the shroud and leaves through lateral apertures. The fuel elements are supported by a spider in the lower end of the shroud and the shroud upper end is closed by a shield. The fuel elements are secured laterally by a spring. Each fuel rod has a lower fissile section and an upper, smaller diameter moderator section. A sudden boiling of the coolant in a fuel element shroud produces an impulsive pressure rise which forces coolant upwards and out through the lateral apertures. The amount of moderator employed is such as to moderate 20-30% of the core neutrons which then have energies in the fuel resonance absorption bands. Doppler broadening of the bands with rising core temperature provides a negative temperature reactivity coefficient.

Abstract: 1356413 Purified Australian antigen PFIZER Ltd 7 Sept 1972 [9 Sept 1971] 42017/71 Heading A5B Purified Australian antigen is obtained by an isopyknic banding technique whereby a blood serum containing the antigen is contacted with the high density end of a liquid medium having a density gradient therein which includes the density of the antigen (c. 1.2), and subjecting the medium and serum to ultracentrifugation until an equilibrium distribution of serum components is obtained and thereafter separating the fraction rich in Australian antigen. Suitable liquid media are Cs Cl and KCl aqueous solutions. Further purification may be achieved by dialysis and further ultracentrifugation in contact with another liquid medium having a density gradient (e.g. sucrose solution) until equilibrium is not achieved; but the serum components, including the antigen, are distributed throughout the medium, the required fractions being subsequently collected.

Title: Circuit fabrication
IPC: H01B1/00
Filed: 1962-11-09
Abstract: In a vapour deposition process of forming an electrical circuit comprising a series of superposed thin films deposited successively on a substrate, each film is deposited through a pair of masks superimposed one behind the other, one mask, defining a common dimension of all the films, e.g. the width, being used during deposition of all the films together with alternative ones of a series of second masks which define the other dimension, e.g. length of said films.  The method is particularly described in relation to the fabrication of an in line cryotron as shown in Figs. 2A and 2B which comprises a substrate 38, a gate conductor 88 of tin, control conductors 90, 92 of lead, insulating layers 94, 96 of silicon monoxide and connectors 98, 100, 102, 104 and 106, 108.  The apparatus for the vapour deposition process is shown in Fig. 1A and comprises a vacuum chamber 10, evaporation sources 30, 32, 34, a substrate 38 and a mask holder 42 which is slideably engaged with a mask support 40 so that a selected mask 44, 46, 48 or 50 may be located over mask 60 which is the first mask positioned over substrate 38.  The mask holder 42 is operated by a connecting rod 62 and the mask 60 which determines the common dimension of the deposits is first located over the substrate 38 and is held in position by a magnet 66.  Mask 44 is then selected and positioned adjacent mask 60 by means of the rod 62 and in this position the first film is evaporated and deposited in the required shape determined by the two masks.  The further layers are then formed by positioning the required mask over mask 60 until the required number or layers have been formed. <PICT:1002359/C6-C7/1> <PICT:1002359/C6-C7/2>

Abstract: 1,075,169. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 6, 1965 [Nov. 27, 1964], No. 42496/65. Addition to 1,055,840. Heading H1C. In a laser in which an active medium 9, e.g ruby, positioned between mirrors 6, 7 serves as a lens so that light from any point on one mirror is focused at a respective point on the other mirror, an output beam controllable as to its direction and intensity is obtained by providing a controlled acoustic diffraction cell 11 within the active medium. As shown in Fig. 1a, the acoustic diffraction cell is energized at an ultrasonic frequency by a piezo-eleotric transducer 13, the transducer being driven by an A.C. signal source of variable frequency and amplitude. The diffracted light pattern produced by the cell 11 is focussed on the mirrors 6, 7 forming the optical cavity, bright highintensity spots appearing in the region of points 30, 32, 34 while the region around points 31, 33 is dark. The highest intensity is found at point 32 in the horizontal plane, intensities of progressively lower values occurring at successive bright points on each side of the plane. The reflections in the horizontal plane are suppressed by stops 36, 37, and since lasing occurs along the axis with the highest Q the emission of coherent light takes place at points 30 and 34. The intensity of the emitted light may be varied by adjusting the signal source amplitude, and the position of points 30 and 34 may be angularly changed by altering the signal source frequency. Emission may be restricted to one of the points 30 and 34 by blocking a portion of mirrors 6 and 7 to spoil the Q along that axis. Alternatively the diffraction cell 11 may be rotated about centre point 8 so that one half of the diffraction pattern falls outside the mirrors 6, 7. Greater control is obtained by the use of second or third diffraction cells 11. The active medium and mirrors may be spherical or cylindrical, and the space between the medium and mirrors may be filled with a transparent material such as glass having a lower index of refraction than the active medium. The point 8 is at the common centre of curvature of the mirrors. Reference has been directed by the Comptroller to Specification 985,204.
