[Also in Division F2] In an A.C. commutator machine the two sets of brush gear 3, 4 are moved in opposite directions around the commutator at different speeds by using an intermediate gear 5 comprising two coaxial pinions 7, 8, having different numbers of teeth, interposed in the drive between pinions 9, 10. The tooth slope of pinions 7, 8 is corrected so that they can both operate at the same centre distance from a mating gear. In order to correct the electrical axis of the brush gear, intermediate gear 5 may be axially disengaged so that one set of brush gear can be moved independently of the other. For reverse running the positions of pinions 7 and 8 are reversed, Fig. 2 (not shown).

Title: Time division switching systems
IPC: H04J3/00
Filed: 1972-09-26
Abstract: 1363549 Automatic exchange systems WESTERN ELECTRIC CO Inc 26 Sept 1972 [1 Oct 1971 (2)] 44362/72 Heading H4K In a system employing a multi-inlet, multioutlet switching network for inter highway switching between groups of T.D.M. highways, the time channels of each incoming highway are distributed over the network inlets. The object is to reduce the risk of blocking by evenly spreading the loads on the highways over the network. The highways may employ P.C.M. transmission. In both embodiments detailed 2-wire and 4-wire lines carrying speech in pulse amplitude form are terminated in a unit which converts 2-wire transmission to 4-wire transmission. Multiplex terminal units sample the resulting 4-wire signals from groups of 128 lines and produce P.C.M., T.D.M. outputs on incoming highways 105 (0 to 6) and distribute and decode the P.C.M., T.D.M. signals on output highways 106 (0 to 6) towards the lines in 4-wire amplitude form. In the embodiment shown each incoming highway is terminated in a unit 401 which converts each P.C.M. code to parallel form and adds the number of the channel from which the code came. Each code is stored in a location corresponding to the channel number in a memory 402. At the same time a decorrelator unit 403 transfers a previously stored code from each memory 402 to a corresponding memory 405, the correspondence between memories being varied cyclically over a number of successive transfers such that a succession of P.C.M. codes corresponding to a single channel are distributed cyclically between the memories 405 regardless of whether that particular channel is active. At the same time connection memories 420 set by the central processor in accordance with the calls actively taking place select locations of the memories 405 corresponding to channels to be sampled and control the first stage 410 of a 4-stage switching network. The decorrelator unit 403 has a spare input 7 and the recorrelator unit 404 a spare output, the input and output being interconnected during normal operation to provide a test path. The network transmits the codes in serial form, shift registers in the memories 405 on the network side performing the necessary parallel to series and series to parallel conversions. The equipment in the lower part of the Figure operates in a generally similar fashion between the last stage 411 of the network and the outgoing highways 106 (1 to 6). The network thus transfers P.C.M. codes for active calls between locations in the memories 405 to provide the required interconnections, these memories being magnetic core memories. The processor controls scanning of the lines directly for call information and employs a memory map of the network to enable a free route to be selected.

Abstract: 1287349 Producing aluminium APPLIED ALUMINIUM RESEARCH CORP 23 Sept 1970 [29 Sept 1969] 45236/70 Heading C7D Aluminium is produced by the reaction of aluminium trichloride and manganese, contacted in counter-current flow. AlCl 3  may be introduced as a gas and Mn as a liquid, liquid Al and a gaseous mixture of AlCl 3  and MnCl 2  being recovered. Some of the liquid Al may be recycled to the liquid Mn inlet to lower the fusion point of the liquid Mn. MnCl 2  may be condensed from the gaseous mixture and the remaining AlCl 3  recycled. The contact may take place in a packed column, a tray column, a spray column, or a wetted wall column. Alternatively, the reaction may take place in a series of reactors containing molten Mn through which AlCl 3  gas is bubbled; the excess AlCl 3  from each reactor being passed into the next in the series, after MnCl 2  vapour present is condensed out. The process is continued until the first reactor contains Mn-free Al; this reactor is then removed, and a reactor containing liquid Mn is added to the end of the series.

Title: Method of modifying a foamed article
Inventor: SKOCHDOPOLE RICHARD ERNEST
IPC: B29C44/56
Filed: 1965-10-26
Abstract: A thermoplastic resinous article, preferably of a sheet-like configuration, having layers of open cells and closed cells is obtained by selectively varying the temperature of at least a first portion of a resinous foamed body having a second order transition point or glass temperature and a plurality of closed cells to a temperature below its glass temperature and thereafter compressing the body, preferably to 10-25% of its thickness, and rupturing the cell walls of the first portion of the body while maintaining at least a second portion of the body above its glass temperature and not rupturing a major portion of the cell walls thereof.  The preferred thermoplastic resin foams are derived from polymerized acyclic olefines, e.g. polyethylene or polyvinyl chloride, and the desired working temperature is achieved, prior to compression of the foamed body, by cooling at least one portion of the body by controlled contact with a suitable heat transfer medium such as liquid nitrogen.  This process may also be modified by cooling the entire foamed body and then varying the internal temperature to give multi-layer configurations of open and closed cells in the product. According to a further modification foams derived from polymerized aromatic olefines such as poly-(o-chlorostyrene), optionally polymerized in the presence of divinyl-benzene, or polystyrene are brought to the desired temperature in a hot air oven and the surface allowed to cool prior to compression of the foamed body. Other suggested resin foams are those of natural and butadiene/styrene rubbers, polyacrylates and flexible polyurethanes.  A method for testing the porosity of the product is described.
