Abstract: 1276131 Gas analysis PHILIPS ELECTONIC & ASSOCIATED INDUSTRIES 19 May 1969 [22 May 1968] 25330/69 Heading G1B The impurities such as water in a gas such as nitrogen are analyzed by passing the gas from 4 to 5 along the space between two concentric tubes 1, 2 c.f. Fig.1 (not shown), passing a coolant gas along the inner tube 1 to establish a constant temperature gradient which is measured and which causes each impurity to condense in a particular zone adjusting the flow of coolant and hence the temperature gradient so that each zone is in turn caused to evaporate, and transporting each evaporated zone in turn by means of a carrier gas into a device 25 for determining the melting point of the impurity forming the zone. From the melting point each impurity may be identified, and from the position of the boundary of each zone on the high temperature end during the initial deposition the concentration of the impurity may be determined. The coolant may be nitrogen gas whose flow is controlled at 27 and which is cooled at 19 by liquid nitrogen, air or helium. The device 25 may be that described in Specification 1265172 and the boiling points of the impurities may also be determined. To produce larger amounts of condensate for the melting point determination, the impurities may be concentrated in a cold trap 15 which may contain a zeolite and then evaporated and transported to the space between tube 1 and 2 by the gas to be analyzed or by a carrier gas.

Abstract: 1526034 Co-ordiriate selection in a rectangular matrix INTERNATIONAL BUSINESS MACHINES CORP 22 June 1976 [23 June 1975] 25777/76 Heading G4H The co-ordinates of a selected point in a rectangular matrix of row and column conductors having drive circuitry arranged sequentially to provide electric pulses thereto, are determined by means of a manipulable sensor 40 with an elongated tip 42 having at least three symmetrically arranged coplanar conductive plates 44A, B, C located laterally of the longitudinal axis of the tip, and sensing circuitry comprising at least two differential amplifiers 54, 63 with respective inputs connected to different conductive plates together with detection circuitry 60, 68, 62 which operates when all differential amplifiers simultaneously generate a null output, so that when the tip is held in proximity to a conductor with the plates capacitively coupled thereto the detection circuitry operates when a pulse is provided to this conductor. With the arrangement shown in Fig. 6, only a pulsed conductor lying within the triangle 72 will result in simultaneous outputs from zero detectors 60, 68 to AND gate 62. The output 71 of AND gate 62 is fed to a further gate 82 which is enabled by the output of a threshold detector 78 provided to eliminate false operation by spurious signals. The output 83 of gate 82 is employed as a DETECT signal which stops a scanning counter whose output indicates the required row or column. The columns and rows may be scanned in turn, or they may be scanned in blocks, a "fine" scan then being performed on the block containing the required conductor. The sensor may be actuated by a pressure sensitive microswitch 48, Fig. 11 (not shown). A sensor with four plates is described with reference to Fig. 9 (not shown). It is stated that the present arrangement of plates and associated circuitry provides increased resolution in the determination of a selected pair of co-ordinates.

Title: Apparatus and method for flexographic printing
IPC: B41F31/00
Filed: 1965-06-18
Abstract: 1,059,753. Printing machines. H. H. HARTWIG. June 18, 1965 [June 30, 1964; May 28, 1965], No. 25788/65. Heading B6C. Ink is applied to the plate cylinder 21 of a flexographic printing-machine by an inking roller 32 or belt having a rigid indented or cellular surface and to which an excess of ink is applied, the amount of ink on the part of the roller 32 contacting the plate being controlled by a resilient-surfaced doctor roller 35 or belt which moves in the reverse direction to the roller 32 at their line of contact C. As applied to a multicolour web-printing flexographic machine, Fig. 1 (not shown), employing halftone synthetic-rubber printing plates, four printing units (11 . . . 14) co-operate with an impression cylinder 19, the units (11, 12) being constructed as shown in Fig. 2 and the units (13, 14) having a modified construction, Fig. 3 (not shown), referred to below. The plate cylinder 21 and inking roller 32 are driven at the same surface speed as the impression cylinder 19, but the doctor roller 35 may be rotated at a surface speed preferably less than that of the inking roller 32. The relative speeds of the rollers 30, 35 may be varied by changing the sprockets 43, 44 over which a drive-chain 45 passes, but a change-speed drive box may be employed. A pool of ink 47 is provided in the nip of the rollers 32, 35 by a wall 48 which has a doctor blade 41 diverting excess ink into a pan 42. A conduit 46 supplies ink to the pool. The doctor-roller bearing 38 is adjusted by a screw 39 so that a constant light but positive pressure occurs between the rolls 32, 35. In the arrangement illustrated in Fig. 3 (not shown) the cellular-surfaced inking roller (51) dips into a reservoir of ink (54). The doctor roll (55) corresponding to the roll 35 is engaged by a doctor blade (60) which diverts excess ink back into the reservoir (54). The relative speeds of the rollers (51, 55) can be adjusted by means of a gear-box (64). According to the Specification, with the devices described, the variation of the thickness of ink applied to the plates lies within permissible limits with variation of press speed, so that the relative speed of roll 35 to the roll 32 and the pressure between the two rolls can be adjusted according to the thickness of ink required while the press is running at a low speed, and the press can then be set to run at normal working speed without further adjustments being necessary. The level of the ink in the pool 47 may be raised as the speed is raised, to prevent turbulence. The inking rollers 32 &c. have a rigid surface of steel treated by milling &c. to provide indentations or cells, and subsequently chromeplated.

Abstract: 646,161. Liquid-fuel burners. SHELL REFINING & MARKETING CO., Ltd., and JOYCE, J. R. Sept. 24, 1947, No. 25935. [Class 75(i)] In a liquid-fuel burner having a vortex chamber 16 supplied through tangential swirl ports and discharging through a spray orifice 14 and controlled by varying the rate of the spill discharge returned to the reservoir and/or by varying the effective area of the tangential swirl ports, the control member can be moved to a setting beyond the minimum supply position whereby a valve member 23 closes the spray orifice 14 of the burner and a communication between the supply and the spillway is opened up adjacent to or in the vortex chamber. In the arrangement shown the fuel passes forward by an annular passage 18 and control is effected by a hollow plunger 15 the base of which serves as the spillway and the surface of which acts as a valve controlling the effective area of the tangential swirl ports 17", 17<SP>1</SP>; the plunger also carries the valve member 23 but this valve member is slidable against the resistance of a spring 26 as the plunger continues its forward movement after the valve has closed the spray orifice 14. In the setting shown (with the valve 23 closing the spray orifice) a circulation of fuel adjacent the vortex chamber is effected by a ported annular groove 22 on the surface of the plunger being in register with the tangential swirl ports 17<SP>1</SP>. As the plunger 15 is returned to the left this communication is first cut .off, then the valve 23 is opened and later the ports 17", 17<SP>1</SP> are opened. The spillway is controlled by a slide valve mechanism (not shown) comprising a ported sleeve and ported plunger attached to the rear end of housing 10 and of a rod extension 20 to the plunger for external manual, electrical, hydraulic or pneumatic control. In an alternative construction Fig. 2 (not shown), ports 37" of smaller diameter than ports 37<SP>1</SP> remain uncovered when plunger is in the fully forward position; the ported annular groove on the plunger surface is omitted. Specification 536,331 is referred to.
