Abstract: 566,302. Spray-producers for fireextinguishing. CARDOX (GREAT BRITAIN), Ltd. (Cardox Corporation). April 23, 1943, No. 6583. [Class 69 (iii)] [Also in Group XXI] For extinguishing fires liquid carbon dioxide passes through a discharge apparatus which first converts it by expansion into a mixture of snow and vapour, the mixture then being deflected in a curved path where centrifugal action separates the mixture into a discharging core of snow surrounded by vapour. The liquid CO2 is forced through a bore 14 against the tip of a cone 23 and flows along a dished curve 24, through orifices 17 and between flared surfaces 19, 26 where partial expansion and vaporisation takes place. The mixture of snow and vapour then swirls round centrifugal chambers 39 where the snow, now on the outside stream, passes to curved surfaces 29 from which the snow issues outwardly in the form of a core while the vapour from 39 is deflected by ridged surfaces 45 towards exit openings 41 from which it issues outwardly surrounding the core of snow. In a modification, Fig. 10, the liquid CO2 impinges against a deflector 50 and flows radially outwards over a dished surface 56 and a centrifugal segregation curve 57 from which the snow flows along the cone 63 to discharge at the apex 64 while the vapour escapes from the cone through radial slot 65 into the discharge space 67 surrounding the snow discharge opening 64.

Patent GB-491799-A (GB)
Title: Manufacture of derivatives of cyclopentano-polyhydrophenanthrene
IPC: C07J75/00
Filed: 1937-03-08
Abstract: Unsaturated polyhydroxy derivatives of cyclopentanopolyhydrophenanthrene are prepared from compounds of the general formula <FORM:0491799/IV/1> where Ac stands for an acyl residue, at least one R stands for acyloxy, the other R stands for hydrogen or acyloxy, and X stands for C = O, C = NH, CHOH, or CHNH2, by a process which comprises saponifying the acyloxy group at position 3, oxidizing to the corresponding 3-keto compound, halogenating, and removing hydrogen halide.  In those compounds in which X does not stand for C = O, the product obtained as described above may be further treated by the usual methods to convert X into C = O.  The application of the process of the invention to 3 : 12 diacetoxypregnanone-20 with the intermediate production of 12-acetoxyprogesterone and leading finally to 12-hydroxy-progesterone, has proved to be especially important. In an example dihydroxypregnanone-20 is esterified with acetic anhydride in the presence of pyridene to give 3 : 12-di-acetoxypregnanone, which is then partially saponified to 3-hydroxy-12-acetoxypregnanone.  This is then oxidized with chromic acid to 12-acetoxypregnanedione-3 : 20, brominated to 12-acetoxy-4-bromopregnanedione-3 : 20, and dehalogenated by boiling with aqueous pyridine to give 12-acetoxy-progesterone, which may be saponified to the corresponding 12-hydroxyprogesterone.  Specification 465,960 is referred to.

Abstract: 398,241. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd. and GRIFFITHS, J. B., Connaught House, Aldwych, London. March 11, 1932, No. 7287. Drawings to Specification. [Class 40 (i).] In a train-describing or train-indicating system provided with local and fast line boards, in the event of a train indicated as on the local line being transferred to the fast line, the fast line indications are stepped back and the local indication is transferred to the fast line board. Should a train not indicated on either board come on to the fast line, for example, from a siding, either all indications on the fast line board are extinguished or all indications are stepped back and a blank indication is displayed in the first position. The final indication on either board can be cancelled. As described, the system is similar to those described in Specifications 366,919 and 371,964. The local indicator board comprises 6 rows of relays, each row storing an indication, the rows being taken into use in turn, and the indications stored on the first three rows being displayed on a lamp indicator board. When the first train has passed the first indicator is cancelled and a sequence switch makes a single revolution during which each indication is stepped up on to the next row of relays. The lamps on the indicator board are extinguished until the first three relay groups have been reset. The main indicator board is of similar construction to the local board but comprises an additional row of relays which cannot be operated by incoming signals. The stepping on of indications is identical with that of the local board. If a local line train is transferred to the fast line, point and signal contacts are closed which start up a third sequence switch. All indications on the fast line board are stepped down, the indication on the sixth row of relays being extended to the additional row referred to above. The top indication from the local board is then transferred to the top row of relays on the fast line board and all the local indications are stepped up as previously mentioned. Should an additional train be passed from a siding on to the fast line a relay is operated, due to the closure of signal contacts, which cuts off the power from the main line indicator signal lamps and extinguishes all indications. Alternatively the relay may control the stepping back of the main indicator relay groups, a further relay being provided to prevent transfer of the first local indication on to the fast board. Under these conditions the first fast indicator displays a blank. The last stored designation on either board can be deleted by the receipt of a signal on the relative cancel wire. Full description of the system and circuit diagrams are given in the Specification.
