Filed: 1965-02-16
Abstract: Nitrogen trihalide, e.g. NCl3, present in gaseous or liquid chlorine is decomposed by contact with an alloy comprising a major proportion of a mixture of copper and nickel.  The preferred alloy contains 60-70% wt. Ni, 25-35% wt. Cu and optionally minor proportions of other elements, e.g. 1-3% Fe, 0.25-2% Mn, 0.02-1.5% Si and 0.3-0.5% C, e.g. "Monel Metal" (Registered Trade Mark). The alloy may be in the form of granular turnings or coarse powder.  The Br2 content of the Cl2 may be lowered to below 100 p.p.m. before contact with the alloy. The contact time may be not less than 0.5 second.  The process may be conducted at ambient temperature. The alloy may be regenerated by washing with water then drying.

Title: Improvements in or relating to oxygen breathing apparatus
Inventor: YOUNG DAVID HERBERT
IPC: A61M16/00
Filed: 1957-03-01
Abstract: 826,454. Respiratory appliances. KIDDE CO. Ltd., W. March 6, 1958 [March 1, 1957], No. 6862/57. Class 81 (2). [Also in Group XXIX] Respiratory apparatus comprises a mask having a loaded air inlet valve, a loaded exhalation valve and a diaphragm-controlled oxygen inlet valve, the first-mentioned valve being set to open at a greater pressure difference than the oxygen admission valve. By this means it is possible for the user to inhale an initial quantity of oxygen, followed by a quantity of diluting air, whereby the oxygen penetrates deeply into the lungs and there is a minimum waste of oxygen on exhalation. Oxygen is received through a pressure-reducing valve 2, Fig. 1, and is passed through a metering jet 3 to a valve 9 controlled by a diaphragm 11 and mounted on the face mask 1. A reservoir 6 is connected between the inhalation valve 9 and the choke tube 3 so that when the user inhales the pressure in this part of the system falls. The changes in pressure are communicated to an annular tube 18, Fig. 2, around the inlet valve 8 and, under normal circumstances it is distended to raise the plate 17 and compress the spring 15 so that the valve 12 is held closed. The fall in pressure in the reservoir 6 on inhalation, however, allows this tube 18 to contract whereby the valve 12 is allowed to open and air is drawn into the mask. If it is desired to supply pure oxygen to the user, a by-pass 5 is opened so that the pressure in the reservoir 6 remains constant and the air inlet valve does not open. The exhalation valve 7 functions in the normal manner for either method of using the apparatus.

[Classes 100 (i) and 100 (ii)] A suction roller feeding device 1 especially adapted for feeding sheets or webs when a printed impression is not dry so as to prevent set-off is revolubly mounted in a suction box S having an opening to expose over a predetermined length and are of the peripheral surface of the roller a predetermined area to which the paper adheres, the interior of the box being in communication with the interior of the roller through perforations in the roller lying within the box. The shaft 3 of the roller is mounted in the end walls 5 of the box, and the inclined sides 7, Fig. 2, are screwed to the bottom 6 and are formed with curved ends which embrace the roller 1 with just sufficient clearance to prevent material inflow of air. In Fig. 3 the sides 9 of the box are vertical and have secured to them curved members 17 which are so close together that the suction acts over a small arc only. In modifications boxes of the shape shown in Figs. 2, 3 are cast in one piece. The rollers may be made with separate compartments so that one roller may deal with webs of different widths, or for a similar purpose part of the periphery of a roller may be masked by steel shields or rubber bands. The device may operate to feed continuously or intermittently, in the latter case imperforated zones may be formed in the roller, or a valve may be provided to connect the suction box intermittently to a suction source, or the roller 1 may be driven intermittently.
