Title: Improvements in gyro integrator with precession rate output signal
IPC: G01F1/76
Filed: 1962-07-19
Abstract: 953,586. Gyroscopic apparatus; photo-electric measurement of gyroscope precession. GENERAL ELECTRIC CO. July 19, 1962 [Aug. 3, 1961], No. 27807/62. Headings G1A and G1C. [Also in Division G4] A gyroscope is used to measure the output of a flow meter of the type described in Specification 717, 897 wherein a signal torque is produced at an output shaft proportional to the flow. The rate of precession of the gyroscope about its major axis, produced by applying the variable signal torque to it about its minor axis, is measured by means including a light source, a photo-cell exposed to light from the source, and a perforate light chopper member coupled to rotate with the gyro about its major axis and periodically interrupting the light falling on the photo-cell from the source, electro responsive means being actuated by the photo-cell output. The torque proportional to the flow is produced at shaft 25, Fig. 1, to cause clockwise rotation thereof. Force rod 29 and arm 36 pivoting at 35 lift and apply a corresponding counter-clockwise torque to the gyro frame 15 via coupling 41, about the minor axis 16 of the gyro. This torque application causes the gyro to precess about its major axis C-C at a speed proportional to the input torque signal. Total precession of the gyro, i.e. total flow, is indicated on counter 51 via gears 52 and 53. Rotating magnets 49 coupled to the gyro rotor 14 produce eddy currents in a tilted conductive ring 50 causing the gyro frame 15 to experience periodic reversing torques about its minor axis 16, reducing the effects of any friction in the system applying the torque from rod 25. For producing a flow rate signal the gyro gimbal 18 drives a disc 58, Fig. 8, through a flexible friction coupling (see Fig. 3), formed with a periphery 59 periodically interrupting the light from a source 55 falling on a photocell 56. The frequency of the resulting pulses in the output of the photo-cell is proportional to the flow rate and is shown on instrument 65 and recorder 66. To compensate for the modulation of the photocell output caused by the repetitive torque action of the ring 50, the axis of rotation of the disc is slightly off-centre with respect to the slotted periphery (see Fig. 4). A resettable batch counter 67 is fed with pulses from a second photo-cell 69 receiving light pulses from a light source 68 through holes 70. To stop random rotation of the disc when the torque applied to shaft 25, Fig. 1, becomes small, a ratchet wheel 62 is formed on the base of the disc 58 and is engaged by pawl 77 when the said torque becomes small, thus stopping the precession. The pawl may be magnetic. Specifications 945, 387, 953, 585 and U.S.A. 2, 585, 693 also are referred to.

Title: Improvements in or relating to the distillation of carbonaceous materials, tar sands, oil bearing limestone or the like, and including apparatus for subjecting the gasesand vapours to the action of liquids
IPC: C10G1/02
Filed: 1927-10-19
Abstract: 306,429. Nielsen, H., and Laing, B. Oct. 19, 1927. Scrubbers; condensing processes.-In distilling oil bearing materials, such as tar sands or carbonaceous materials, the oil vapours are subjected to fractional condensation in separate scrubbers at successively lower temperatures by a liquid medium which is brought into contact with the vapours by moving- mechanical means, the liquid being of a different specific gravity or boiling point in each scrubber. Each scrubber contains a pair of shafts 2 having discs 3 which are driven in opposite directions and serve to spray the liquid in the scrubber into the oil vapour which passes through the scrubber from the inlet 9 to the outlet 10. Perforated screens 8 prevent oil in - the iiquid form from reaching the outlet. The hot gases on entering the first of a series of scrubbers 12 - - 15 are treated with oil which is vaporized, and this oil is condensed in and supplied from the succeeding scrubber 13 by pipe 16 overflow vessel 17, pump 19, receptacle 21, and branch pipe 24. The oil in the scrubber 12 passes by a pipe 16 to a vessel 17 and outlet pipe 18. Scrubbers 13 and 14 are supplied with oil in a similar way and the last scrubber 15 either with oil of the same specific gravity as that which it is desired to collect or with water, the residual vapours passing to an oil scrubber 31 having any suitable filling.

Title: Improvements in or relating to electronic computing machines
Inventor: SMITH KENNETH LESLIE
IPC: G06F9/30
Filed: 1958-08-29
Abstract: 881,881. Electronic computors; magnetic core matrix stores. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 24, 1959 [Aug. 29, 1958], No. 27883/58. Class 106 (1). A computor using a two-address code has two magnetic-core matrix stores 1 and 2, each having a capacity of 16 numbers of 10 decimal digits (plus a sign digit), and an instruction from programme unit 74 set up in instruction register 70-73 selects a number from each store (units 70 and 71 via address decoders 68 and 69), delivers an order to arithmetic unit 28 (unit 73 via order decoder OD), and routes one of the numbers back to be rewritten in its original position and replaces the other by the calculation result under control of unit 72. Each matrix comprises four arrays of 16 X 11 cores, the numbers being stored in binary-coded decimal form and read out in serial-parallel mode by successive energization of the 11 column lines SL1-SL1 by read unit 154. The decimal digits read-out at 7-10 and 15-18 are passed to the arithmetic unit 28 and the result passes through either gates 55-58 or 59-62 to be entered into store 1 or store 2 in place of one of the numbers read out, according as line 66 or line 67 is energized from unit 72, the other store receiving back its original number via gates 83-86 and 95-98 or 79-82 and 91-94. Units 75-78 in the return path for the latter number provide a delay equal to that of the arithmetic unit 28 so that simultaneous writing of the two numbers can be effected by write unit 155, the decimal digits being set up in cores 139-142 and 150-153 in complementary form; when a core is reset by a pulse on line 144 an inhibit winding of the appropriate array is energized to prevent the appropriate core selected by the address line AL1-AL16 and the scan line SL1-SL11 being reset. A unit 64 provides the timing pulses (Fig. 4, not shown) for control of address, read, and write units, the cores 139-142 and 150-153 and the routing gates of Fig. 1B.

Title: Method for purification of antitoxins and the like
IPC: C07K16/12
Filed: 1935-10-09
Abstract: Antitoxins and other antibodies contained in serum, blood, or plasma are purified and concentrated by subjecting the serum or the like to partial digestion with pepsin, papain, rennin or a like enzyme, under acid conditions at an acidity not greater than pH 4, preferably at pH 4,2.  The digestion is continued until from 70 to, at most, 90 per cent of the proteins are rendered non-coagulable on heating.  It is stated that the serum albumin is digested, the euglobulins are partly digested and partly precipitated, and the pseudoglobulins are substantially unchanged and retain their antibody activity.  The enzyme should be added to the serum before, simultaneously with, or immediately after acidification so as to avoid destruction of the antibody. According to an example diphtheria antitoxic serum is diluted with saline solution, digested with pepsin at pH 4,2 for two days at 37 DEG  C., and filtered, and the liquid so obtained is subjected to ultra filtration to reduce its volume to about 1/16 of the original.  In place of ultra filtration other methods of concentration, such as dialysis and evaporation, precipitation or absorption, may be employed.  Antitoxin prepared by known methods, such as fractional precipitation with ammonium sulphate, may be employed as the starting material.  The process may be applied also to other antitoxins such as those of tetanus, erysipelas, staphylococcus, dysentery, and gas gangrene, to antivenoms such as those of crotalus, cobra and moccasin venom, and to anti-bacterial serums such as those of distemper, pneumonia, meningococii, staphylococci, and dysentery.  The antitoxins of hemolytic streptococci, perfringens, vibrion septique, aedema, histolyticus, sordelli, botulinus are also referred to.

Abstract: 1,040,159. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. June 17, 1963 [July 23, 1962], No. 28323/62. Heading G6C. A fuel element of the kind comprising a column of right cylindrical fuel pellets enclosed in a thin-walled tubular metallic sheath, the ends of which are closed by end caps welded in the ends of the sheath, has a load-bearing pellet provided, in frictional engagement with the sheath, between each end of the column of fuel pellets and the end caps, whereby should a fuel pellet jam in the sheath at reactor operating temperature such that the fuel pellets on one side of the jammed pellet are held one against the other between the jammed pellet and the load bearing pellet at the corresponding end of the sheath, contraction of the sheath, relative to the fuel pellets, on fall of the sheath temperature below reactor operating temperature results in loading of the load bearing pellet against the pellets so that loading of the end cap closing the corresponding end of the sheath against the pellets is minimized or prevented and the weld between the end cap and the sheath is protected from deformation. A fuel pellet may become jammed by the coolant pressure locking the sheath to a particular pellet, e.g. due to an oversize pellet or due to a hot spot. Another possibility is that the coolant pressure or irradiation may cause fracture of one or more of the pellets and one or more fragments may wedge in contact with the sheath. In one embodiment (Fig. 2, not shown), the load bearing pellet 9 is of beryllium (in the case of a beryllium sheathed fuel element) or, more generally, sintered alumina, and is of slightly larger diameter than the fuel pellets 1, the sheath 2 being externally pressurized to lock by engagement with a circumferential groove 11 around the pellet 9. Alternatively, (Fig. 3, not shown), a sintered alumina pellet 12 is is used with a gap 14 left between it and the end cap 4, the sheath 2 being externally pressurized to engage by friction with the pellet 12 and with a shallow groove 13 around its circumference. As the sheath 2 contracts on cooling, the pellet 12 is forced along it to close the gap 14.

Abstract: 703,607. Moulds; cores. GENERAL MOTORS CORPORATION. Nov. 13, 1952 [Nov. 14, 1951], No. 28596/52. Class 83 (1) A process of reinforcing a thin-walled mould or core for casting comprises coating the back of the mould or core with a mixture of comminuted refractory material and a waterglass solution, and then drying the coating. Two thinwalled mould halves 12 are shown, and the coating 10 which, e.g., consists of 98 per cent sand, 1 per cent commercial waterglass containing approximately 37 per cent sodium silicate, and 1 per cent additional water, may either have a flat exterior surface 11 or follow the contour of the mould half as at 13, and be between ¢ and 2 inches thick. The drying comprises baking the mould half and its coat in a circulating air oven at a temperature within the range of 300‹ F. to 700‹ F. The water glass may consist of sodium silicate, potassium silicate, a mixture of these two, or sodium tertrasilicate. In the case of cores, the coating consists in filling the interior of the 'core with the mixture. The mould halves and core are made by allowing a dry mixture of sand and resin powder, e.g. phenol formaldehyde or melamine formaldehyde, to contact a hot metal pattern to thereby form a shell on the pattern, which is subsequently aired at a temperature between 300‹ F. and 600‹ F.
