Title: Process of treating carbon articles
Inventor: BICKERDIKE ROBERT LEWIS
IPC: C04B35/52
Filed: 1957-12-19
Abstract: A porous carbon or graphite article is impregnated with carbon from a gaseous or vaporous carbonaceous material at a steady temperature within the range of 500 DEG -1500 DEG C.  Under such conditions of pressure and flow rate that deposition of soot on the surface of the article is avoided.  Carbonaceous materials specified are carbon monoxide, carbon tetrachloride, methane, ethylene, propane, and benzene.  The carbonaceous material may be in admixture with nitrogen or argon.  The article may be heated in a vacuum vessel at a pressure of less than 1 mm. of mercury before impregnation.  In one embodiment (Fig. 1, not shown) a graphite disc is maintained at 750 DEG C. in an electrically heated furnace which is alternately evacuated and charged with benzene vapour. In another embodiment (Figs. 2 and 3, not shown) a graphite or carbon tube is maintained at a temperature of 750 DEG -850 DEG C. and a stream of nitrogen, followed by a stream of nitrogen containing benzene vapour, is passed over the specimen at atmospheric pressure.  In a modification a stream of methane at 975 DEG C., or ethylene at 800 DEG C. may be employed.  In another modification (Fig. 4, not shown) a graphite tube is evacuated to a pressure of less than 5 microns of mercury and is then heated first at 1800 DEG -2200 DEG C., e.g. 1900 DEG C., and then at 500 DEG -1500 DEG C., e.g. 1400 DEG C., by the passage of an electric current therethrough, whereafter a current of propane at a pressure of 20-30 cm., e.g. 22,5 cm., of mercury is passed over the specimen. Impermability values are given.

Abstract: 1,056,278. Valves. SEETRU Ltd. Oct. 17, 1963 [Oct. 19, 1962; Nov. 7, 1962], Nos. 39564/62 and 42012/62. Heading F2V. [Also in Division G3] Valve.-A pressure selector comprises a spool 2, Fig. 1, in a ported sleeve 3, which spool controls flow from an inlet 35 to an outlet 36 and from the latter to an exhaust port 37; the spool is loaded to a central position by a spring 6 in opposit on to outlet pressure acting beneath the spool. The spring 6, which is disposed in a sleeve 5, is adjustable by a piston 7 and the spring loading is supplemented by fluid flowing to the exhaust port 37 through the sleeve 5. Fluid flows to or from the outlet 36 when the spring loading is increased or decreased until such time as the outlet pressure again balances the spring-loading whereupon the spool is once more re-centred; the latter position provides sufficient flow to the outlet 36 to replace losses. The piston 7 is movable by a hand-lever with an adjustable friction-clutch 21 at the fulcrum. The outlet 36 is also connected to a chamber 44 open to a shoulder 45 on the rod 9 of the piston 7, whereby movement of the latter changes the volume of the chamber 44 and hence the pressure at the outlet 36, so providing an unbalancing force to reinforce the spring load and overcome spool " striction." Servomotor.-An element, such as a rudder 51 (Fig. 4, not shown) is actuated by a jack 52 under the control of a valve 63 which is positioned in dependence upon the output pressures from two pressure selectors 1 and 56, which pressures are applied to opposite ends of the valve 63. One selector 1 is remote and manually adjusted whilst the other selector 56 is connected to the rudder.

Title: Josephson junction memories
IPC: G11C11/44
Filed: 1974-09-17
Abstract: 1450343 Josephson junction memories INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1974 [20 Sept 1973] 40349/74 Heading H3X A Josephson junction device is switchable between different, overlapping vortex modes containing different numbers of flux quanta to write in and read out digital data. In a matrix of such devices the column members are serially connected with respect to a word current I w  and are associated with rows of one or more conductors carrying a bias current I co  and a bit current #I c  which combine to switch a particular device from one vortex mode to another. For example, a device is stable in either mode in the overlapping area 3 between the (0-1) and the (1-2) modes Fig. 1 under the lines 1, 2 respectively. Application of I co  and I w  switch the device to the (1-2) mode if it wasn't already so and subsequent removal of these currents leave the device in area 3 but stable in (1-2) mode. Currents of I co - #I co  with I w , however, switch the device to the (0-1) mode. Read-out is effected in the same maner but the energy change associated with mode switching is sensed by diverting the energy change pulse via inductors (9, 12, Fig. 4, not shown) to a further device (11) which changes from the superconducting to voltage state, thereby transferring bias current (I bo ) to another device (15) which also changes to the voltage state with a larger, detectable current output. The device 5 may have a physical construction causing the mode overlap to be such that switching is possible without I co , thereby additionally preventing data loss in the event of current failure.

Title: Improvements in fluidic systems and fluidic devices therefor
IPC: G01B13/00
Filed: 1969-08-13
Abstract: 1,274,276. Fluid regulation; fluid-pressure servomotor systems. ATLAS COPCO A.B. Aug. 13, 1969 [Aug. 26, 1968], No.40499/69. Headings G3H and G3P. [Also in Divisions G1] The body of a fluidic device 1 has formed therein a substantially venturi-shaped main passage having inlet and outlet portions 3 and 4 respectively, and a signal passage 6, the passages being rectangular in cross-section and so disposed that the angle 7 between the signal passage 6 and the centre line of the main passage lies between 20 degrees and 60 degrees, and is preferably equal to 45 degrees. The signal passage is arranged to intersect the main passage at the minimum cross-sectional area portion 5 of the main passage and at this branch-off point the main passage cross-sectional area increases discontinuously in a direction from the inlet 3 to the outlet 4. With the above arrangement and in the absence of an impedance downstream of the outlet portion 4, flow within the inlet portion 3 adheres, inter alia, to wall 9 thereof, detaches itself from the wall at the point of intersection of the main and signal passages, and re-attaches itself to a wall 8 of the outlet portion at a point downstream of the intersection. Thus no flow enters the signal passage 6. Upon introducing an impedance downstream of portion 4, flow from the inlet portion 3 can be distributed between the portion 4 and passage 6, or diverted entirely into passage 6, Figs. 2a, 2b, 2c (not shown). Alternatively, Figs.3 and 4 (not shown), more than one signal passage may be provided. When applied to controlling a valve, Fig. 6, the device is connected to a signal source 33, an adjustable restrictor 34 and a signal responsive control 31 which may comprise a deflectable membrane to which a valve spindle is secured, the position of this spindle being determined by the state of restrictor 34 and hence by the pressure in signal passage 6.

Abstract: 1,028,367. Respiratory appliances. PYE Ltd. Oct. 13, 1964 [Oct. 15, 1963], No. 40548/63. Heading A5T. A volume cycled medical ventilator comprises a bellows to be connected to a gas supply and a changeover mechanism (operated by a certain degree of expansion of the bellows) which opens a valve for gas to flow from the bellows for inspiration, the changeover mechanism also being arranged (on a certain contraction of the bellows) to close the valve to allow expiration to take place. As shown, the bellows 1 at the end of the expiration phase, are expanding and by moving the arm 3 about a pivot 4 are about to actuate the changeover mechanism 9 through a pin 29, an adjustable wedge 30, and a pin 28. The rocker arm 20 then moves so that it is held by the magnets 24, 26 and a rod 6D opens the inspiration valve 6A and closes the expiration valve 6B. Gas from the bellows then passes via an adjustable constrictor 10 to the patient. The resulting contraction of the bellows finally actuates the changeover mechanism through a pin 31 and the rocker arm is held by the magnets 23, 25. The inspiration valve then closes, the expiration valve opens, and the patient exhales through a vent 8. The ventilator also includes a magnetic pressure relief valve 12 in which is a signal whistle, and a source of suction may be applied to the vent 8 for an induced exhalation phase. Springs 27, 33, control the action of the changeover mechanism and movement of the wedge 30 controls the volume of inspiration gas. Extreme movement of the wedge permits the apparatus to be used for manual operation.

Title: Parallel-to-serial code converter

Abstract: 1,013,159. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 26, 1962 [Oct. 28, 1961], No. 40614/62. Heading G4H. [Also in Division H3] In a circuit for converting a 1-out-of-x representation of data into a corresponding number of pulses an appropriate number of diodes in a chain of series-connected tunnel diodes TD1 to TD4, Fig. 1, having progressively increasing switching voltages, are simultaneously switched from their normal high impedance state to a low impedance state and then they are sequentially switched back to their high impedance states. As described, data in a 1-out-of-5 input code is entered by depressing and releasing an appropriate key K1 to K5 and output pulses are produced by a monostable circuit OS on a lead a or a lead b. Depression of a key changes some of the diodes to the low impedance state and release of the key produces a positive pulse at a point P which, via a capacitor Ck, turns on the monostable circuit OS (" on "=Tr1 conductive, Tr2 non-conductive). While this circuit OS is on a transistor Tr3 controlling current flow through the diodes is cut off and a capacitor C charges. Eventually the monostable circuit OS turns off-thereby marking the end of the first output pulse-but transistor Tr3 remains cut off for a further period determined by a circuit R1, C. When capacitor C is discharged transistor Tr3 becomes conductive and the normal relatively high voltage is applied across the chain of diodes. If, when this occurs, any diode is in its low impedance state then that one with the lowest switching voltage changes to its high impedance state first and in so doing it produces a positive pulse at P as before. This immediately turns on the monostable circuit OS which, in turn, cuts off the transistor Tr3 so that no more diodes can change their states at this instant. A further output pulse is then produced as before and the sequence repeats until every switched diode is returned to its normal high impedance state. Thus the output pulses have a length determined by the recovery time of the monostable circuit and the gaps between the output pulses is determined by the time constant R1C.

Abstract: 1,037,747. Seals. BORG-WARNER CORPORATION. Oct. 15, 1963 [Dec. 26, 1962], No. 40621/63. Heading F2B. A seal for sealing a submersible electric motor against the ambient liquid in which both the motor and the seal are immersed comprises a housing having a chamber 32 which communicates with the motor and the ambient liquid and contains lubricating liquid and an intermediate liquid which has a specific gravity greater than that of the lubricating liquid and separates the latter from the ambient liquid. The motor 10, Fig. 1 (not shown), drives a pump 12 through a shaft 18. The lubricating intermediate and ambient liquids may be oil, water and well liquid respectively. The seal housing comprises four chambers 44, 45, 46 and 32 separated by three mechanical seals 35, 36 and 37 each comprising a rotary seal member urged by a spring into contact with a stationary seat. The chamber 44 is open at its upper end to the ambient liquid and communicates via bore 54 and tube 55 with the chamber 32. The chambers 45 and 46 also communicate with the chamber 32 via bore 48 and tube 50 and bore 51 and tube 52 respectively. Ports 31 connect the chamber 32 with a space 30 which communicates through bores 28 and 24 in the shaft 18 with the motor lubricating and cooling oil system. Prior to submersion in a well, the motor and seal housing are first filled with lubricating oil, and water is then introduced into the bottom of chamber 32 through plug 59. The water displaces oil from the chamber 32 through the tube 55, bore 54 and chamber 44 until the oil-water interface 61 reaches the open end of tube 55, the supply of water being continued until it fills the tube 55, bore 54 and chamber 44. The plug 59 is then replaced. When the motor and seal are submersed leakage along the shaft 18 is prevented by seals 35 to 37 and an interface between the water and the well liquid is formed within the tube 55, which interface rises or falls within the tube when expansion or contraction of the oil in the motor and chamber 32 occurs.
