Title: Improvements in or relating to automatic telecommunication exchanges
IPC: H04Q3/545
Filed: 1961-12-08
Abstract: 945,534. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 8, 1961 [Dec. 8, 1960], No. 44052/61. Heading H4K. In a system in which two sets of functional units are associated with separate time division cycles, for part of each cycle, the control arrangements for the two sets are associated independently with their respective acts of functional units, whilst a different part of the cycle is used for transfer of information between the control arrangements. As described, the two sets of functional units are subscriber's lines 1 and a lesser number of links 3 which are required to be connected over a switching network 2 under control of a marker 8. The lines 1 are scanned by a device 4 using pulse positions as shown at A, Fig. 3, the positions TK1. . . TKn being used for scanning and the positions TK for information transfer. The links 3 are scanned in accordance with the cycle shown at B, Fig. 3, each link being associated with a period such as TL1 equal in duration to three of the periods of A, the first third of a B-period coinciding with a TK period of A. Storage device 71, Fig. 2, contains records of the subscriber's lines loop condition, and when a subscriber goes off hook this is detected by the scanner 4 and the result compared with the line's record in the storage device 71, and after a persistance test the change is recorded in the line store 61 and the identity of the line is fed to a transrer store 9. When the scanner 5 next detects a free link the line's number is transferred to the control circuit during the TK portion of the TL period associated with the link and during the subsequent TG period the line's number is transferred to a portion of the store 72 associated with the link, and the link is marked busy. The marker 8 then establishes connection between the calling line and the link under control of circuits 61, 62. During subsequent scanning of the seized link, during the period TK, the subscriber's identity is fed from store 72 to control circuit 61 to cause scanner 4 to test the subscriber's line directly, this result being recorded in the store 71. Information as a result of the simultaneous scanning of line and link are interchanged between circuits 61, 62 during this period. Towards the end of the TL period the new information received by 62 is transferred to 72 which thus has an up-to-date record of the progress of the call. With slight modifications the arrangement may be used for setting up connections from links to called lines. In a large exchange comprising several interconnected arrangements like Fig. 1, the above technique could be used for transferring information between control circuits of the different arrangements.

A further panel 33 is folded back to underly panel 32, both panels 31 and 33 being substantially covered with ink to prevent information on panel 32 being read by holding the label up to the light. A side panel 37 is folded either before or after folding panel 31, and the panel 34 is folded down to overly panel 32. Finally short panel 35 is folded to underly panel 32. The folded label is secured by adhesive applied along margin 31b and on panel 37, and also along the margins of panels 33-35 on the rear surface of the blank. A further panel 36 is detachably secured to panel 32 and bears common identifying indicia with the front of panel 34. Alternatively, the rear surface of the blank may be coated with heat-sensitive adhesive and the right- and left-hand margins of panels 31 removed, panel 37 being omitted. After folding, the label is compressed and heated to seal the panels together. In a further heat-sealed modification the panel 35 may be omitted and all three margins of panel 31 may be reduced in size. The fourth panel (equivalent to panel 34) may be provided to the right of panel 33, panels 37 and 35 being omitted, and the right and top margins of panel 31 removed. After folding panel 33 to underly panel 32, the fourth panel is folded round the right-hand edge of the label to overly panel 32, and the label heat sealed as before. Finally, the blank may only comprise four panels (Figs. 13 and 14, not shown) corresponding to panels 31-33 and 36, and the common identifying indicia are printed on the rear of the top panel. Adhesive is supplied round the margins of the front of the top panel, and the margins of the rear of the bottom panel. The label is adapted for " blind clinical trials," wherein the nature and dose of a medicament are printed on the second panel 32, but only the patient's number and the " trial " number are exposed on the common identifying panels. The labels are adhered to a drug container by the further panel, and the main portion is detached by a clinician and kept with a patient's record. If it is necessary to determine the nature and dose administered to a particular patient, the main portion may be opened without disclosing information of other samples of drugs being used in the same trial.

Title: Process and apparatus for the production of carbon black
Inventor: CLAASSEN EDWIN JACK
IPC: C09C1/50
Filed: 1961-12-19
Abstract: Carbon black is produced in a reaction chamber of circular cross-section by continuously introducing a reactant hydrocarbon stream of fluid in the chamber, passing the stream axially through the chamber without it contracting the peripheral wall, heating the stream in the zone to decompose the hydrocarbon to carbon black by heat interchange with a gaseous heat donating stream of fluid, and removing a portion of the stream containing the major portion of carbon black axially from the chamber and cooling to recover the carbon black, the heat donating stream being forced tangentially through the peripheral wall into the chamber near the inlet end and maintained at a sufficiently high velocity so that it forms a vortex which blankets the peripheral wall, a portion of the heat donating stream is removed at the outlet end.  The heat donating stream may be preformed by mixing air or other oxygen containing gas or vapour externally of the furnace, or the air may be introduced alone and used to burn a portion of a suitable hydrocarbon gas, vapour or other combustible material within the furnace.  The furnace may be cylindrical or tapered.  The hydrocarbon reactant may be liquid or gaseous at NTP.  The temperature of the heat donating stream may be 2700-3200 DEG  F. at the inlet end and 2400-3000 DEG  F. at the outlet, and the axial outlet stream is usually 2100-2700 DEG  F.

In the specific embodiments compositions which are violet or purple, are made using two pigments whilst black compositions are formed using cyan, magenta and yellow pigments. The particles may be made by adding the pigments to molten low MW polyethylene and cooling while agitating to give encapsulated pigment particles. Alternatively a solvent suspension of the pigments together with copoly-styrene-butyl methacrylate is spray dried. The resultant encapsulated pigment particles are dispersed in sperm oil together with low MW polyethylene, tricresyl phosphate #-carotene, a polymer and kerosene and on a conductively-coated glass cylinder. Many suitable insulating liquids electrically photosensitive pigments, polymers and supports are specified. The encapsulated pigments may include FeO, CuO or dyes to control the colour of the particles.
