Abstract: 291,750. Erban, R. June 7, 1927, [Convention date]. Friction gearing.- In epicyclic roller gearing of the type in which one or more races are expanded or contracted to provide the necessary pressure for drive, the resilient race, which may be split or continuous, is of such form when in action that the rollers are completely or almost completely out of contact with the race at at least one point in each revolution.

Abstract: 1,237,799. Discharging arrangement for cyclones or filters. HILMAC CONSULTANTS (PTY) Ltd. 31 March, 1969, No. 16666/69. Headings BIT and B2P. [Also in Divisions B8 and F2] A solids flow control valve for a separator, e.g. a cyclone separator or a fabric filter, comprises a flexible, e.g. rubber, diaphragm 5 made of at least three separate sector-shaped elements which, when the valve is closed, abut each other along their respective edges and when the valve is opened, flex outwardly to provide a central passage for the discharge of solids from the separator. The diaphragm is in the form of an inverted cone and is mounted within a shell 8 with its outer peripheral portion clamped against a flange 3 by which the shell is secured to the solids outlet of the separator. Each sector-shaped element has stiffening ribs 7 along the radial edges of the sector on the outer surface thereof. In operation, a negative pressure is created within the separator and serves to hold the sector-shaped elements together until the weight of accumulated solids overcomes the force created by the negative pressure. A central passage is thereupon formed by outward flexing of the elements permitting discharge of the solids. Immediately after discharge the elements flex inwardly to automatically close the valve. Inward flexing of the diaphragm elements is limited by stops 10 secured to the wall of the shell 8 and connected by flexible shanks 9 to the elements. Reference has been directed by the Comptroller to Specification 1,170,966.

Title: Improvements in the production of carbon black from natural gas
IPC: C01B31/00
Filed: 1928-06-09
Abstract: 317,165. Winter, R. M., and Imperial Chemical Industries, Ltd. June 9, 1928. Carbon.-Carbon and hydrogen chloride are produced by reacting chlorine with a hydrocarbon-containing gas by causing the gases to combine in a flame burning in air or by mixing the gases to form a combustible, inflammable or explosive mixture, at a temperature below the ignition temperature, and burning the mixture in a steady, controlled manner, if desired in air, the products of combustion being in either case collected. In one form, the chlorine is burned in an envelope of hydrocarbon-containing gas which is surrounded by air, a suitable form of burner consisting of two concentric tubes, the chlorine being introduced through the inner tube. In a further form, the burner consists of a number of concentric tubes, the chlorine and hydrocarbon being introduced through alternate annuli and the outer envelope of hydrocarbon gas burning in air. Where the chlorine and the hydrocarbon-containing gas are mixed before combustion, the mixture may be effected in a device similar to a Bunsen burner, the mixed gases being led through the tube at a velocity greater than that of back-firing. The atmosphere around the flame may consist of reaction products together with excess of chlorine or of the hydrocarbon gas, but preferably the flame is exposed to air. The initial gas mixture may contain a little air or oxygen, in one form of burner, chlorine and hydrocarbon gas are supplied through tubes 3, 4 respectively to a mixing chamber 1, packed with material 2 such as pieces of earthenware, so as to form an explosive mixture. The mixture issues from a tube 5 and is ignited at the orifice thereof. The suspended carbon is separated, e.g. by settling, electrostatic precipitation, filtration, or by a combination thereof, and the residual gas washed with water to obtain aqueous hydrochloric acid. Examples in which coal gas and natural gas are employed are given in the Specification. One of the Provisional Specifications describes the use, as the chlorine source, of electrolytic chlorine or of the gas from the Deacon process containing chlorine, hydrogen chloride, steam and oxygen.

Title: Electrolytic production of perchloric acid
IPC: C25B11/10
Filed: 1957-05-28
Abstract: 818,335. Electrolytic production of perchloric acid. MERCK A.G., E. May 28, 1957 [July 5, 1956], No. 16958/57. Drawing to Specification. Class 41. A process for the production of perchloric acid is characterized in that an aqueous solution of perchloric acid of a concentration between 10 and 60 per cent by weight containing dissolved elementary chlorine is subjected to anodic oxidation, preferably at below room temperature. The cathode may be of graphite, or silver, platinum, copper or their alloys. The anode may be of metals of the platinum group and alloys thereof. Typically, an aqueous solution of perchloric acid is pumped from a supply container to a cooler and thence passed to a stage where it is saturated with chloric and thereafter to the anode space of a two-compartment cell where part of the dissolved chlorine is oxidized to perchloric acid at a platinum anode. The acid is run from the anode space back to the supply container. Part of the electrolyte at the anode is transferred to the cathode space through a stretched polyvinyl chloride porous diaphragm to make good the dilution of the electrolyte in the cathode compartment due to migration of chlorate ions to the anode. After the removal from the cathode outflow of the amount of perchloric acid corresponding to the output of the cell the remainder is also led back to the supply container. The water used up is replaced by addition to the supply container.

Title: Testing bistable memory cells
IPC: G11C11/412
Filed: 1975-04-25
Abstract: 1476040 Testing electrical circuits INTERNATIONAL BUSINESS MACHINES CORP 25 April 1975 [26 June 1974] 17153/75 Heading G1U In testing a bi-stable memory circuit, a first binary value is written into the circuit, then a second binary value is written in over a time longer than normally required for writing and thereafter the cell is inspected to determine whether it contains the first or second value. An array of memory elements is arranged in rows and columns each having a selecting line from a line driver 10, rows, and a bit decoder 12, columns. Each bistable comprises cross-coupled F.E.T's Q3, Q4 load transistors Q1, Q2 and switching transistors Q5-Q9. Associated with each column of memory elements are isolating transistors Q10, Q11 which connect the common input lines BL1, BL2 to data input terminals DI, DI via switching transistors Q12, Q13. The input lines BL1, BL2 are common to each column of elements and are connected together at nodes B o , B 1 . To test the operation of the load transistor Q1, a 'high' signal is applied to terminal R, turning on transistors Q7, Q8, Q9 which precharge the input lines BL1, BL2 with Q9 ensuring equal potentials on the two lines. At the removal of this signal, the line driver 10 and bit decoder 12 provide signals selecting the particular element to be tested in the array. These 'high' signals turn on transistors Q5, Q6, Q10, Q11 in the selected element. At this point a 'write' signal is applied to terminal R/W thereby turning on Q14. A 'I' signal is applied to the data input terminal DI thereby turning ON transistor Q12 and holding off transistor Q13. At this point, point A in the element is grounded via transistors Q10, Q12, Q14 and the element is thus set, current flows through Q1 to hold Q4 off even if the write signal is removed. The signal on the data input is now reversed and held at 'O' for a predetermined period much longer than normally necessary for writing. If Q1 is good, point A will slowly charge up through Q1 and B will immediately fall low. After the predetermined time, the write signal at terminal R/W is removed. If Ql is good the memory states are unaffected by this. On a normal restore signal, R and a normal read cycle, the output of B1 will be sensed by amplifier 14 as low, i.e. the second value, if the transistor is good. If Q1 is open circuit, when the second write signal, 'O' is applied, point A will not charge up and at the removal of the write signal point B will charge up since no current will flow through Q1 to hold Q4 off. Thus in the normal read cycle, point B1 will indicate the first value read in and the element can be seen to fail. The transistor Q2 can be similarly monitored by first writing a 'O' followed by a long 'I'.
