Title: Method and apparatus for photographic printing
IPC: G03B27/80
Filed: 1968-08-23
Abstract: 1,217,024. Exposure control. AGFAGAEVERTA.G. Aug.23, 1968 [Aug.25, 1967], No.40465/68. Heading G2A. In a method of photographic printing, the image of an original to be printed is scanned to determine a portion thereof of a size smaller than the total image area and having an overall contrast greater than any other image area of the same size, and light originating only from the portion of the image determined is transmitted to a photo-electric exposure regulating means. In a colour projection printing apparatus for carrying out this method, light from a lamp 1 passes through a condenser 3 and the original 4 and is reflected by a semireflecting mirror 8 through dichroic beam splitting mirrors 9, 10 on to contrast measuring arrangements 11, 12, 13 each provided with a diaphragm 7. The measured contrast values are passed to an evaluating device together with the co-ordinates of the diaphragms, each of which can be brought into several distinct positions in succession. Thus the position of each diaphragm for maximum contrast in each colour is determined, and the diaphragms are set to these positions before exposure. The device 14 then controls colour filters 15, 16, 17. In another embodiment Fig. 3 (not shown) two photo-cells (22), (23) are arranged behind a diaphragm (21) having two apertures. The photo-cell (23) is placed behind a diffusing plate (24) and its signal is used directly to control the exposureregulation. In a further embodiment Fig.4 (not shown) each of two cells (28, 29) sub-divided and the sub-divisions separately connected to an evaluating device (30). In a further embodiment (not illustrated) continuously moving masks are used to determine the position mentioned above.

Abstract: 1401515 Jet fuel LUMMUS CO 31 Aug 1972 [2 Sept 1971] 40481/72 Heading C5E A petroleum fraction 62 boiling in the kerosene range is mixed with a mixture 60 of branched-chain olefinic hydrocarbons having an average of 9 to 16 carbon atoms per molecule. The mixture is passed from line 42 through a catalyst bed 16 at 200-75‹ F. in admixture with a cocurrent of hydrogen. The liquid effluent from the bed 16 is contacted at 250-450‹ F. with a countercurrent of hydrogen in the catalyst bed 18 to produce a stream 50 of jet fuel. If the feed does not need to be preheated the fresh kerosene enters at 43 and the olefinic feed is mixed from line 41. The olefinic hydrocarbon can be olefin oligomers, e.g. propylene trimers and tetramers, butene trimers and tetramers, and mixed oligomers of butenes with ethylene and/or propylene, boiling in the range 280- 525‹ F. The petroleum fraction 62 generally boils in the range 300-550‹ F. and can be a hydrodesulphurized straight-run kerosene, heavy naphtha, furnace oil or catalytically cracked cycle oil. The mixed feed generally comprises 10-50 volume per cent of the olefinic hydrocarbons. The gaseous effluents from the zones 16 and 18, comprising hydrogen and normally liquid hydrocarbons, are cooled at 52, 30 and 32 and separated at 34 into a stream 36 of recycle hydrogen and a liquid stream 44 which is recycled. The catalysts used can be Raney nickel or Ni, Pt or Pd on alumina, silica, kieselguhr, diatomaceous earth, magnesia or zirconia. The hydrogen introduced at 26 can be cold. The jet fuels produced can have aromatics contents of below 1 volume per cent and freezing points below - 57‹ F.

Title: Improvements in or relating to the carrying out of heterogeneous exothermic reactions in the liquid phase
Inventor: ALEXANDRE MARCEL
IPC: B01J19/00
Filed: 1958-12-19
Abstract: A solid finely-divided catalyst is suspended in a liquid phase and a gaseous reagent continuously passed therethrough; the vaporized reaction product removed with the vaporized liquid phase is continuously separated and the gaseous reagent continuously recycled. The temperature may be below or above the boiling-point of the reaction product at the pressure employed, but if above, a solvent is used which remains liquid under the reaction conditions.  Preferably the liquid phase is mechanically agitated throughout the reaction. If the reaction is carried out in a plurality of stages, the condensate from each stage is used to feed the next one until in the last stage the liquid phase contains the desired concentration of reaction product which is continuously separated from the vapours removed.  In examples, octene-2 and isobutylene dimer are hydrogenated with nickel catalyst, and methyl ethyl ketone hydrogenated with nickel or kieselguhr as catalyst.ALSO:Ethylenically unsaturated compounds (e.g. octene-2, or isobutylene dimer, in presence of nickel) or ketones (e.g. methyl ethyl ketone in presence of nickel on kieselguhr) may be hydrogenated by means of a process wherein the catalyst is suspended in a liquid phase and the hydrogen continuously passed therethrough; the vaporized reaction product which is removed with the vaporized liquid phase being continuously separated and the hydrogen continuously recycled.

Title: Evacuated collection tube closures and assembly
IPC: A61B5/154
Filed: 1972-09-07
Abstract: 1388494 Withdrawing liquids CORNING GLASS WORKS 7 Sept 1972 [7 Sept 1971] 41548/72 Heading A5R [Also in Division B8] An evacuated closed collection tube 22 for use as part of an assembly for drawing fluids eg. blood from the body comprises a hollow body having a bore, one end closed and the other end open and having a sealing closure 39. The closure 39 consists of a malleable thin metal foil (preferably aluminium) cap 40 or a preformed metal cap (Figures 10-12, not shown) having a crown portion 42 and an annular collar portion 44 extending downwardly along but spaced from the collection tube 22 (the central portion of the crown is of reduced thickness to facilitate piercing by a hollow needle). A disc-shaped layer of self-sealing resilient material 55 forms a seal between the open end 25 of the collection tube and the crown portion 42. The seal may be self-adhering or may be fixed to the inner surface of the crown portion 42 by means of a suitable adhesive 56. The seal prevents air escaping into the tube round the cannula during intake of fluid and prevents leakage of liquid after removal of cannula. In order that the closure 39 may be completely impermeable to gas a bulk sealant 58 is placed 'between the outside surface of the tube 22 and the inner surface of the collar 44. In order to facilitate placement of the sealant a skirt portion 52 is formed at the lower edge of the collar 44. The sealant may be adhered to either of the surfaces with which it is in contact or it may just form a compressive seal between these two surfaces, being kept in position by the pressure differential between the inside of the evacuated tube and the surroundings. Figures 6-9 (not shown) illustrate an alternative embodiment wherein the metal cap is formed from a disc of foil and folded into the required shape. The bulk sealant (58) is applied to the metal disc before folding to ensure complete sealing. Other alternative embodiments, Figures 10 and 12 (not shown), have the seal (120) (164) between the crown (116) (158) and the open end of the tube and the bulk sealant (114) (162) combined. In a last embodiment Figure 11 (not shown) the metal cap (128) is shaped to fit the end 24 of the tube and the seal (130). In order to remove the withdrawn body fluids from the collection tube, the metal foil cap is severed with a knife and removed, or a pull-tab (70) Figure 4 (not shown) may be provided. Where a preformed metal cap (Figures 10-12) is provided, this is removed with a known bottle cap lifter.

Abstract: 889,722. Superconductive circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1958 [Dec. 27, 1957], No. 41610/58. Class 40 (9). [Also in Group XIX] In a multi-stage stepping circuit, each stage is operable to represent information stored therein and adjacent stages are coupled together so that information may be sensed when adjacent stages are operated. Each stage comprises a number of cryotrons arranged in two parallel circuits, one of which is conductive and the other resistive when the stage is operated. The cryotrons may be of wire or film-type, the latter being as described in Specification 862,178. Horizontal control windings 16, 17, Fig. 3, when energized separately have no effect on a vertical conductor IN-1, IN-2, but when energized simultaneously, increase the resistance of this conductor which may therefore be called a gate. Each stage, Fig. 1, comprises two paths. When current is flowing through gate B3, control winding C3, and gate D3, the third stage is off. When current-flow through gate A3, control winding A1, control winding B3, gate C3 and control winding E4 the third stage is on. Assuming that stages 1 and 2 are initially on and stages 3 and 4 off, then the application of a P1 pulse to stages 1 and 3 turns on stage 3 and turns off stage 1. Potential for reading out was initially applied to terminal 20 through gates C1 and C2 in series and this potential is now switched to terminal 21. A pulse P2 applied to stages 2 and 4 then steps the pattern again.

Title: Circuit arrangement for bridging a potential level including a chopper amplifier
IPC: H04N5/63
Filed: 1971-09-10
Abstract: 1338664 Bridging a signal across potential levels; cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Sept 1971 [15 Sept 1970] 42360/71 Headings H3T and H4T Output signals from an amplifier SV are fed to a point of different D.C. level, e.g. to the control electrode of a C.R. tube, via a first path including an isolating capacitor 9 and which carries the higher frequency components and by a parallel path carrying the D.C. and lower frequency components. According to the invention the second path includes a resistor 12, a chopper CH connected to the path via a diode 15, an isolating capacitor 13 and a D.C. restoring diode 16 followed by resistor 14 to recover the D.C. and lower frequency signal from the chopped signal. As described, the input signal 1 is of pulse form and may be accompanied by a video signal applied at 19. The pulses bottom the transistor so that resistor 18 may be used to vary the amplitude of the pulses at the collector without varying the lower level. The diode serves to limit the chopping pulses at the level of the signal and the effect of varying resistor 18 is thus to vary the D.C. level of the signal after D.C. restoration by diode 16. A plurality of amplifiers may be connected to respective loads using a common chopper (Fig. 3, not shown). In Fig. 2 (not shown), the two paths are used to convey respectively the field and line frequency parabolic focusing connection signals for a colour tube of the type in which beams from three cathodes pass through a single gun. In Fig. 4 (not shown), two circuits are used to apply a signal to the control electrode and in inverted sense to a focusing electrode of a double beam tube, the focusing electrode signal serving to prevent displacement of the beams with respect to each other due to the density modulation of the beams.
