Title: Gas Chromatographic Separation Process
Inventor: BARRERE CLEM A
IPC: G01N30/34
Filed: 1968-04-09
Abstract: 1,165,864. Gas chromatography. CONTINENTAL OIL CO. 9 April, 1968 [20 April, 1967], No. 17090/68. Heading B1L. Gas mixtures are chromatographically separated by feeding one component of the mixture to the carrier gas stream passing through the column until equilibrium is reached, after which the mixture to be separated is injected into the carrier gas stream. Thus, carrier gas containing component B from tank 30 is passed by line 20 through column 18 until equilibrium is reached. Until this state occurs, the amount of B drawn from tank 30 is controlled by composition controller 40 which governs solenoid control valve 42. The sample to be separated comprising components A and B is then injected by line 22, with continued circulation of the carrier gas mixture with component B. On leaving the column 18 in sequence, the separated components A and B are directed by valve 24 to tanks 28, 30 respectively. Before, between and after emergence of A and B, the gas flow is directed by valve 24 through cooler 26, to eliminate any A or B which may be entrained. In Fig. 3 (not shown), the separation of a 3-component mixture is illustrated. In examples, (1) using a silica gel column and helium as carrier gas, <SP>14</SP>C 3 H 8  was separated from <SP>12</SP>C 3 H 8 ; (2) using a capillary column coated with triethanolamine and nitrogen as carrier gas, <SP>14</SP>CO 2  was separated from <SP>12</SP>CO 2 ; and (3) using a nickel-kieselguhr column and hydrogen as carrier gas <SP>14</SP>C 2 H 6  was separated from <SP>12</SP>C 2 H 6 .

Title: Electrophotographic duplicator
IPC: G03G15/22
Filed: 1968-04-10
Abstract: 1,210,666. Electrostatic printing. ADRESSOGRAPH - MULTIGRAPH CORP. 10 April, 1968 [21 April, 1967; 14 March, 1968], No. 17285/68. Heading B6C. [Also in Divisions G2-G3] A powder image, loosely held by an electrostatic image on a recording member, is transferred to a receiving sheet by bringing the sheet into contact with the powder image and applying a pressure less than eight pounds per square inch to effect the transfer. In one embodiment of a long run duplicating apparatus, shown in Fig. 7, a recording member 20, comprising a photoconductive layer (24, Fig. 1, not shown), e.g. of zinc oxide in a resin binder, on a conductive backing (25), is clamped round an earthed cylinder 80, and a powder image 95<SP>1</SP> formed thereon by corona charging at 82, exposure at 90 to an original 92, and magnetic brush developement at 98. This powder image is transferred to a copy sheet 102 at a transfer station 100 by applying a pressure between transfer member 108, comprising a conductive core 112 and soft rubber layer 110, and the cylinder 80 when sheet 102 contacts the powder image. A voltage from source 114, applied between core 112 and cylinder 80 enhances transfer, and the transferred image may be fixed on sheet 102 by pressure rollers 72, or by heat fusion. Development by brush 98 is controlled by applying a field from a source 99 between the brush 97 and the cylinder 80. In another embodiment (Fig. 8, not shown) the powder image (127<SP>1</SP>) is fixed on the recording member by a heat fuser (110), the fixed image is recharged, developed again with a magnetic brush, and the redeveloped image transferred as before. Alternatively, after transfer, the recording member is recharged and re-exposed to the same original, in registration with the first exposure, this latent image then being developed and transferred as before. The pressure between the transfer roller and cylinder is accurately adjusted by a control (170, Fig. 9, not shown), which includes micrometers (198) for setting the gap between the roller and cylinder. The duplicating apparatus is automatically controlled by a circuit (Fig. 10, not shown).
