The same access switches are used by a routiner and a traffic recorder. The access switches AS1 may be provided on the basis of one per hundred, say, final selectors, if mounted on a separate routiner access rack or one may be mounted on each rack of final selectors. Routine testing. Key KR operates relay H in the routine access control unit RACU to prepare the routiner test unit RTU which seizes over its primary distributer PD the first access switch AS1. Relay B earths lead RMD whereupon MT, MS (not shown) in the control unit RACU operate the vertical magnet VM of the access switch AS1, relays MT, MS releasing when the magnet interrupters VMC remove the earth on lead RMD. Switch R in the control unit RACU steps to its fourteenth outlet and MS, MT, which re-operate when the vertical magnet interrupters VMC close, operate the rotary magnet RM of the access switch. The control of the relays MS, MT is taken over by the test unit RTU which steps the access switch AS over its first level and tests the final selectors connected thereto. The c-contacts of unused outlets are strapped to a lead UN so that the lead RMD is earthed when such an outlet is reached. At the eleventh outlet of the level, contacts S1 close a circuit to the control unit RACU which releases B, whereupon the access switch AS1 rectangularly returns to normal. The control unit RACU steps the access switch AS1 over each level and then steps its primary distributer. PD to connect another access switch. Traffic recording. Key KTR operates TRC which transfers control of the access switch to the traffic recorder control unit TACU. A start relay ST locks up on receipt of a pulse (one per 36 seconds) from lead EP. Relays X, Y interact and a switch P consisting of four double-ended wipers sweeping eight levels in four revolutions is stepped by relay Y at 6 steps per second. Wiper switching relays SA, SB, SC successively connect the pairs of levels of the switch P to relays VR, RR and these relays, pulsed by relay Y as the switch P is stepped, energize the vertical and rotary magnets of a meter-connecting switch MCS to cause each of its wipers to rotate over hundred outlets in ten levels associated with each access switch. Each wiper is connected by TRC to the p-wiper of an access switch, and all the access switches are stepped in unison with the meter-connecting switch MCS by the relays VR, RR so that any engaged final selector is noted by the traffic recording meters connected to the outlets of the switch MCS. The meter-connecting switches MCS may be replaced by an extra wiper on each access switch. Specification 450,019 is referred to.

Title: Improvements in and relating to the refining of sublimable materials
IPC: C22B5/16
Filed: 1941-06-20
Abstract: 552,254. Magnesium ; sulphur; sublimation, apparatus for. MAGNESIUM METAL CORPORATION (American Magnesium Metals Corporation). June 20, 1941, Nos. 7819/41 and 9789/42. [Class 82 (i)] [Also in Group III] In a process and apparatus for refining sublimable materials, particularly magnesium, but applicable also to other materials, e.g. zinc, cadmium and sulphur, the speed of flow of vapour from the material to the condenser is controlled to prevent the carrying over of any impurities into the condensed product. In the case of magnesium, the speed may be not more than about 4.5 metres per second. The apparatus shown comprises a condenser C, which may be surrounded by a cooling coil 10, and a retort R mounted within an electrically heated chamber 4. The condenser and retort are arranged to be exhausted through a pipe 24, and the chamber 4 through a pipe 28, so that the walls 2 are not subjected to stresses. The material to be treated, which may be tablets or granules of magnesium dust with or without a binder, is charged through a central pipe 18 through the condenser into the retort where is occupies the space around a series of coaxial truncated conical members 22 which are surmounted by a perforated conical hood 23. The vapour evolved passes through the narrow spaces between the members 22 into the relatively larger central space where its speed is reduced, and thence through the hood 23 into the condenser, where it is deposited in solid form. The deposit may be received on a removable metal liner 8 which may be split to facilitate removal of the deposit or may be made of the material being sublimed, e.g. pure magnesium. In a modification, chains depend in the condenser near its walls and the body of condensed material embeds the chains and may be lifted out of the condenser which is of inverted conical form. Specification 381,115 and U.S.A. Specification 2,240,817 are referred to.

Title: Improvements in filters for protection against gas, dust, arsines, toxic fumes and liquids sprayed in the atmosphere
IPC: A62B23/00
Filed: 1936-03-16
Abstract: 468,084. Air-filters. DUNEME, L. March 16, 1936, No. 7846. [Class 8 (ii)] [Also in Group VI] In filters, employed in closed chambers for protection against noxious liquid and solid particles and gases in the atmosphere, and comprising several filtering elements in series, at least one element is constituted by a portion of a band adapted to be wound from one spool to another in steps to expose successive portions of the band for use as preceding portions are exhausted. As shown a gas-mask filtercanister 6 of curved formation comprises a band 1 in series with a pleated paper filter 2 and active carbon or like material which may be enclosed in a separate container within the canister. The band 1 may be of paper, fabric, mineral wool or impregnated felt and is arranged to be wound from a spool 3 upon a spool 4 by means of a key, the spools being enclosed in chambers defined by walls 11, 12 and having tensioning means. In front of the filter 2 the band is guided upon and pressed against flanges upstanding from the base of the canister and from a top wall thereof removable for refilling. The edges of the band may be strengthened or compacted by the application of strips of the material known under the Registered Trade Mark " Cellophane," which may be stretched before apply-. ing, or by impregnation with gum, wax, or solid paraffin. Transverse strips of " Cellophane " may also be used to mark off the band in sections, for consecutive use. The filters 1, 2, may be clogged in known manner to reduce the pore size, the band 1 being less heavily treated than the filter 2. The canister may have transparent windows and the band may be coloured, for example black and white in alternate sections, or otherwise marked to facilitate correct positioning thereof. Air enters the canister through an aperture 13, and leaves through an aperture 20. In a modification, several bands may be arranged on separate pairs of spools one behind the other for successive use, the ends of the bands having apertures or comprising the stiffening strips only to present no filtering surface before and after use. In a further modification a folded paper filter, employable in place of the band, is arranged behind it and is connected at its ends to one side of the canister which side has a second inlet orifice. The inlet of the filter not in use is closed by a plug.
