Title: Control of an automatic signalling system
Inventor: OBERMAN ROELOF MAARTEN MARIE
IPC: G21C1/00
Filed: 1952-11-06
Abstract: 762,274. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Nov. 6, 1952 [Nov. 12, 1951], No. 28017/52. Class 40(4). In an automatic exchange system, a marker obtains information concerning the busy or idle condition of links between all successive stages capable of setting up a call between a calling and called subscriber, chooses a set of mutually accessible links, and then obtains access to control circuits and feeds them with information sufficient to set the switches to establish a connection between the two subscribers via the chosen links. Fig. 1 illustrates the trunking layout for a 9000- line exchange divided into 4¢ groups of 2000 lines. Each 2000 line group contains 40 sub groups of 50 lines, each sub-group being served by ten primary switches. Ten secondary switches of 40 outlets serve these primary switches. The secondary switches are cross-connected via feedbridge circuits cord, the arrangement being such that each connection can be established via any of 10 primary-secondary links, 20 feed-bridge circuits and then 10 more primary-secondary links. In the control arrangements, Fig. 2, the calling line obtains access to a register REG in known manner, and the latter receives both the calling and the called party's number. The register then transfers this information to a marker. Switches MSA, MSB and MSC are then set to receive notification of the busy or idle condition of such links and feed-bridge circuits which could complete the connection. A free route is then chosen and switches MSD, MSE are set to appropriate control-circuits which are then fed with appropriate setting information. Each control circuit is arranged to control one group of secondary switches and also the primary switches to which this group of secondary switches has access. Such a group is shown enclosed in dotted lines. Each group of secondary switches may consist of a single crossbar switch. Likewise all the primary switches controlled by one control circuit may be combined in a single cross-bar switch or group of cross-bar switches effectively acting as one cross-bar switch. Such a cross-bar switch will not have its outlets (on the subscriber side) multipled within the switch in the usual manner 'but will have 2000 individual outlets. These 2000 outlets will however be multipled over similar positions in 10 such cross-bar switches. By such an arrangement failure of one of the control circuits effects all subscribers of the 2000- line group equally, but reduces the degree of service only by a small amount. Specification 762,273 is referred to.

Abstract: 690,809. Sheet-delivery apparatus. HEAD WRIGHTSON MACHINE CO., Ltd., LAKE, N. C., and BATTY. F. A.. Oct. 31. 1950 [Nov. 2, 1949], No. 28113/49. Class 100(i) [Also in Groups XIX and XXX] Apparatus for classifying sheets both of ferrous and non-ferrous metals and other substances comprises a feed conveyer on to which the sheets to be classified are fed and other conveyers arranged in two or more independently operating groups and including sections moving at successively reduced speeds for operation in conjunction with one or more diverter gates by which sheets from the feed conveyer are transferred to a selected group of the other conveyers, and suction means arranged at intervals throughout the length of said other conveyers for holding the sheets in position on these conveyers. The figures show the application to a plant wherein the sheets are cut from a metal strip which is unwound from a coil 1, passed through a series of rollers 3, a group of rollers 4 for trimming the sheet to the required width, flattening rollers 5, and then finally cut into sections by a cutter 6. The successive sheets are then graded into different piles according to their gauge and this is effected by a classifying unit indicated generally at 7 and consisting of three groups of endless belt conveyers on to one of which a sheet is diverted by gates controlled by a " flying " micrometer 8. The sheets from the cutter 6 are first received by a belt conveyer A mounted on rollers X, Y, Z. A sheet of standard gauge passes from this conveyer over gates G, G<SP>2</SP> to a series of conveyers A<SP>2</SP>, A<SP>3</SP>, A<SP>4</SP>, A<SP>5</SP>. When a sheet of smaller or greater gauge than standard passes over the micrometer 8, an electrical impulse is transmitted from the latter to mechanism controlling the gates G, G<SP>2</SP> and one of these is opened whereby the sheet is diverted either to the series of conveyers B, B<SP>1</SP>, B<SP>2</SP> or to C, C<SP>1</SP>, C<SP>2</SP>. Each conveyer in these series of conveyers travels at a lower speed than the preceding one, and the sheets fall off the last conveyer of each series to be collected in a pile or stack. The sheets are secured to the conveyer belts by suction applied through nozzles N connected to a main suction conduit P. Each conveyer preferably comprises two spaced bands, D, Fig. 4, formed with holes H overlying slots S formed in the surface plate K of each nozzzle, the belt resting on this plate. Each conveyer may however comprise a single band formed with transverse slots cooperating with longitudinal slots in the face plate of the nozzle. Specification 478,448 is referred to.

Filed: 1972-06-20
Abstract: 1374710 Yarns JOHNS-MANVILLE CORP 20 June 1972 [24 June 1971 (2)] 28803/72 Heading D1W [Also in Divisions B5 and F2] In the manufacture of friction facings e.g. for a clutch plate or brake mounting, two or more rovings composed of parallel glass filaments impregnated with a heat-curable cement are grouped together in parallel relation and continuous filaments of metal e.g. non-ferrous such as brass or zinc, are helically wound therearound to retain the rovings in a continuous bundle. The latter is spirally or randomly wound into a desired shape and dimension and then compressed, the cement is cured and the resultant body is ground to a required thickness. Prior to the rovings being wrapped, the cement e.g. 30-40% rubber, 20-30% accelerator and curing agent such as di-orthotolylguaridine, 15-30 resin and 20-30% filler, may be at least partially dried to remove volatile materials. As shown in Fig. 1, glass rovings 12 withdrawn from package 10 are maintained apart by a combing device 14 as they pass around a roller 16 in a cement bath 18. Impregnated rovings pass through eyelet 22 which wipes off excess cement, they are separated again in passing through rosette disc 24 (which may also remove any remanent cement) whence they pass through a drying tower 26 through which a counter stream of steam is passed between ports 28 and 30 to drive off volatile hydrocarbon parts of the cement. The partially dried rovings pass over pulleys 32, 34, and through a tower 36 wherein hot air is admitted and exhausted to and from ports 38 and 40, 42, thence through a winding apparatus 60 wherein filaments, supplied from symmetrically disposed spools carried by a continuously revolving platform 62, are wound in spaced helices around the rovings. The wound bundle passing axially through the platform is wound for storage onto a spool 50 by driven friction rollers 54, 56, such action providing the tractive force for passage of the continuous rovings through the apparatus. Subsequently the wound bundle 49, Fig. 7, is spirally or randomly wound from a spool 88 onto a revolving mandrel mould 90 comprising a pair of plates 92 mounted on a rotatable shaft 94 and spaced according to the desired thickness of the disc preform, the latter is removed from the mandrel, compressed between flat platens, initially cured by heat applied thereat and the curing is completed by a subsequent backing under reduced pressure in two stages of temperature conditions. The disc so formed is then ground and drilled to final size and to provide securing means.
