Title: Method for the recovery of sulphur by means of reduction of sulphur dioxide
IPC: C01B17/04
Filed: 1934-06-13
Abstract: In the production of sulphur by the catalytic reduction of sulphur dioxide by carbon monoxide, masses of aluminate or smelt cement are used as the catalyst, the percentage of alumina being at least 25 and preferably 35.  The efficiency of the catalyst is increased by the addition of iron or manganese compounds preferably oxides or hydroxides, e.g. bog iron ore.  The reduction may be effected at 350 to 650 DEG  C.

Title: Improvements in or relating to telephone systems
IPC: H04M15/10
Filed: 1925-07-09
Abstract: 259,311. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), (Scruby, S. V. C., Turkhud, B. A., and Fromery, F. de). July 9, 1925. Metering systems.-Unsuccessful incoming calls and successful outgoing calls are recorded on a meter BSM with the aid of a pair of thermionic valves L1, L2, the usual meter SM recording only outgoing calls. When the line is idle the plate current in valve L2 keeps relay RCR energized and when the line is seized the connection of one test relay to the cwire does not lower the negative potential on G1 sufficiently to produce any effect. When a second connector tests the busy line, however, the potential on G1 becomes such that the condenser K is able to discharge through R3 and the valve L1, positive potential on grid G2 is reduced and relay RCR falls back and operates the meter BSM. When the discharge, is over relay RCR disconnects the meter and when the unsuccessful connector moves away the condenser is slowly recharged through resistance R4. Successful outgoing calls are metered by the application of booster battery to the c-wire. When the connection is released to operate the meter SM, this impulse also operates the meter BSM. In case both outgoing and incoming calls a.re metered normally the meter BSM records these as well as the unsuccessful calls. In manual exchange systems the meter BSM is operated in response to the usual busy test with the tip of the calling plug. Jacks J1 - - J3 are provided for plugging up measuring instruments.

Title: Improvements in and relating to revolving doors
IPC: E06B3/90
Filed: 1930-08-11
Abstract: 359,375. Revolving doors. COLMAN & SONS, Ltd., T. B., Mortimer Road, and COLMAN, T. B., Redlynch, Davigdor Road, both in Hove, Sussex. Aug. 11, 1930, No. 17784/31. Divided on 360,858. [Class 20 (iii).] Relates to revolving doors of the kind in which the wings, normally retained in the radial position by bolts arranged on a cross-arm secured to the central spindle, may be folded together and will also collapse under undue pressure. According to the invention, the bolts are connected together so that they are released together or in pairs. In one construction, the bolts 2, Figs. 1 and 2, are mounted within a cross-arm 1 secured to the central spindle i of the door. To the bolts are connected rods 4 which are secured to a flange 3 loosely mounted on the spindle i. Each bolt is pressed outwardly by a spring 5 and carries a pin 6 which is adapted to project through an opening 8 in the cross-arm to hold the bolt in a retracted position. By this arrangement, all the bolts are retracted when any one is moved, but do not return to their normal positions until all the pins 6 are released from the openings 8 by plates 7 secured to the wings. The bolts are retracted, when undue pressure is exerted on the door, by members 9 mounted one on each wing. Each member 9 is mounted to yield against the pressure of a spring 10 but is normally locked by a spring-pressed pin 11 which enters a recess in a casing 12 secured to the wing. A pin 13, resiliently mounted in the casing 12, has a vertical arm which extends between the member 9 and the bolt 2. When the wing collapses, the pin 13 is released and a cam surface 14 thereon raises the pin 11 and thus releases the member 9 which is then free to yield against the pressure of the spring 10 should it foul the cross-arm. Two flanges 3 may be provided and the bolts are connected thereto in pairs. The members 9 may be rigidly secured to the wings. The Provisional Specification describes also an arrangement wherein spring-pressed bolts carried by the wings engage in recesses in the cross-arms and thus maintain the wings in a radial position.

The member 2 may be moulded integrally with a marginal flange 3, it may be cut away as at 4, and it may be mounted on a screw threaded pin 8 so as to be adjustable both circularly and as to its distance from the front glass 1. In addition a segmental member 9 may be rigidly mounted in contact with the rear face of the front glass 1. The sectorial member 2 may be made of glass with one or both of its surfaces marled, mottled, satinised, frosted or otherwise made translucent, the front glass 1 may have its marginal edge marled, mottled, satinised or frosted, the segmental member 9 may be made of translucent glass, and the members 1, 2, 3 and 9 may be blue, amber or otherwise coloured. In one modification the sectional member is secured in position by means of a channelled arcuate flange member which engages around the edge of the front glass 1, and in a second modification a flat circular disc of glass has one portion treated to provide the sectorial member and the remaining portion left untreated.
