Title: Apparatus and method for analyzing particle volume distribution
IPC: G01N15/12
Filed: 1974-04-18
Abstract: 1457657 Particle analysis COULTER ELECTRONICS Ltd 18 April 1974 [18 April 1973] 17100/74 Heading G1N The invention relates to measuring the PARTICLE-VOLUME DISTRIBUTION in a liquid suspension. Particle pulses from e.g. a Coulter scanner are sorted into different SIZE RANGES (instead of counting the total number above each size limit as in Specification 1330587). The pulses are applied to a plurality of comparators 31, 36 with different threshold levels and also to a "pulse stretcher" which stores the maximum amplitude. The comparators control leading and trailing edge detectors and VETOAND circuits so that the pulses within a size-range are switched to the appropriate pump-circuit to be accumulated in the integrator for that range, Fig. 1A, B (not shown). The veto circuits are automatically reset after each pulse by the lowest range trailing-edge detector. Calibration. OR-circuits in each channel connected to a common reference line enable the  trimmer capacitors in the pump-circuits to be set Fig. 1B (not shown). Modifications. A separate "pulse-stretcher" circuit may be provided for each range and connected through a resistor to its integrator instead of employing pump circuits.

Title: Improvements in or relating to television receiving apparatus
IPC: H04N5/64
Filed: 1946-06-05
Abstract: 627,568. Television receiving apparatus. P.R.T. LABORATORIES, Ltd., BAYBUT, H., and GALE, A. J. June 5, 1946, No. 17126. [Class 40 (iii)] In a television receiver the cathode-ray tube is mounted in such a manner that the viewing screen end thereof may be moved from an inoperative position within an associated cabinet to an operative position external to and above the cabinet, the movement between the two positions serving to operate switch means controlling the energization of associated apparatus. As shown in the drawing, a cathode-ray tube 10 is carried by a movable member 11 which is pivotally mounted about a horizontal axis near to its uppermost rear edge within a cabinet 12. The member 11 is provided with a self-erecting mechanism comprising a spring-actuated toggle lever system 29 which, when a catch mechanism 38 engaging a projection 43 is released, operates to raise member 11 from a position within the cabinet to the position shown in the drawing. In this latter position a projection 44 engages the catch 38 and serves to lock the member 11 in its raised position. Alternatively the pivotal mounting may be arranged to allow a horizontal movement of the member 11 so that the lower front edge of the latter can be supported by the upper edge 27 of the cabinet. A toggle switch in the power supply circuit of the vision apparatus is operated by the raising and lowering movement of the member 11. In the lowered position the upper surface 13 of 11 forms a continuation of the upper surface of the cabinet and in the raised position a flexible curtain 28 forms a dust-tight closure between the cabinet and the member 11. Controls requiring adjustment during television receiving are exposed for use only when the viewing screen is exposed by mounting them with recesses in one or both of the side walls of 11. Instead of employing a spring mechanism for effecting the movement of the viewing screen means such as a rack and gear mechanism or an electric motor driven mechanism may be employed, or the viewing screen may be arranged to be lifted manually with the raising of the cabinet lid. Instead of a pivotal movement the member 11 may be arranged to execute a vertical up and down motion by means of suitable guides within the cabinet. Pre-set controls 61 are located at the bottom front of the. cabinet and normally concealed from view by a movable panel 19.

Title: Improvements in methods and apparatus for producing uranium fluoride
Inventor: VERTES PAUL
IPC: C01G43/06
Filed: 1955-06-14
Abstract: <PICT:0800692/III/1> In the preparation of uranium fluoride by reaction of uranium oxide with gaseous hydrofluoric acid, the oxide is compacted to form pellets and then treated in a downwardly flaring tube with an upflowing stream of hydrogen fluoride.  In the apparatus shown, uranous oxide in the form of pellets which may have a diameter of 6 mm. is introduced into flared tube 1 of nickel or other resistant material through opening 10 and hopper 2 whilst hydrogen fluoride is passed into a circular casing 4 arranged round the exit of the tube 1, and passes through the charge, excess passing out at 9.  The reaction is started by means of an electrical resistor 8, and after it has begun the temperature may be controlled by means of a stream of air or other fluid in a casing 5, heat exchange being assisted by fins 7.  The movement of the pellets through the furnace may be continuous or (in the specific embodiment shown) successive charges may be added and the uranous fluoride periodically discharged by means of the gas-tight slide closure 12.  Entry of air into the tube must be avoided, e.g. by maintaining the upper part of apparatus at a slight sub-atmospheric pressure so that the pressure in the vicinity of the lower discharge means 12 is substantially equal to or above atmospheric pressure.

Abstract: 314,015. Kinugasa, S., and Hashimoto, S., (Assignees of Kinugasa, N.). June 21, 1928, [Convention date]. Waterproofing.-In a process of waterproofing cloth, paper, &c., calcium carbonate is added to an aqueous solution of alum and acetic acid, the solution is stirred, and the material to be waterproofed, previously impregnated with an aqueous solution of soap, is dipped into the upper layer of transparent solution. For example, 5 parts of alum are dissolved in 15 parts of water, and the solution mixed with 6 parts of a 36 per cent solution of acetic acid. 2.3 parts of precipitated calcium carbonate is mixed with 3 parts of water, and added to the first solution. After the evolution of gas has ceased, the upper layer of the solution is decanted off. The material to be proofed is dipped into a solution of 100 grams of soap in 18 litres of water, and then into the decanted solution. It is then washed in water and dried. The process is particularly adapted for proofing natural and artificial silk, as the lustre, colour, and softness of the material are preserved. As compared with the known process using successive baths of soap and alum, adequate proofing with the use of a smaller quantity of alum is obtained. In the Specification as open to inspection under Sect. 91 (3) (a) aluminium sulphate is used and not alum as in the foregoing description. In the Specification as accepted alum only is specified.

Title: Improving heat capacities of hydroforming recycle gas
IPC: C10G35/14
Filed: 1954-06-14
Abstract: <PICT:0756707/IV(a)/1> In a process for hydroforming petroleum naphtha, the product vapours from the hydroforming zone are condensed at a temperature not below 120 DEG  F. so that a substantial proportion of lower boiling hydrocarbons are retained in the uncondensed gaseous phase and the heat capacity of the gaseous phase is increased, separating the gaseous phase from the liquid condensate, reheating the gas to a temperature above that in the hydroforming zone and recycling at least a portion of the reheated gas to the hydroforming zone.  A preferred apparatus for carrying out the invention comprises a reaction zone 1 containing a bed of fluidized, powedered, catalyst C, to which is fed virgin naphtha through line 2 and recycle gas at a temperature of about 1200 DEG  F. through line 3.  The crude product leaves the reaction zone through a gas-solids separating device 4, and then traverses coolers 6 and 7 and into a scrubber 9, in which a heavy oil is charged through line 10.  Heavy polymers are condensed and rejected through line 11.  The uncondensed material is passed after cooling to 140 DEG  F. to a separation drum 13.  Recycle gas from the separator may be passed through line 14 to recycle compressor 15, if desired propene or mixtures of C1 to C3 hydrocarbons being added through line 23.  The recycle gas then passes through a compressor 15, heat exchanger 6, a furnace 18 and then back to the reactor 1.  A residual portion of the recycle gas is passed through line 30 into absorber 19 where the gas is stripped of C4 and C5 hydrocarbons by feed entering through line 20.  The feed enriched with C4 and C5 components is withdrawn from the bottom of absorber 19, through line 21, heat exchanger 7, furnace 18 and back to reactor 1.
