Lewis, of Sunny Bank, New-road, Ynysybwl, in the county of Glamorgan.—The invention particularly relates to an improved construction of regenerator adapted to be attached to harness on the wearer, so that the regenerator becomes located on the wearer’s back. The regenerator according to this invention consists of a flat rectangular case of suitable metal, fitted at its open upper end or top with a lid preferably hinged, and which is held closed in an air-tight manner by a series of hinged bolts fitted with wing nuts, so that by loosening the wing nuts and turning aside the bolts the lid can be quickly and easily opened, and access so obtained to the interior. The interior is sub- divided by a series of sheets of wire gauze corrugated, the corrugations of one sheet contacting with the corrugations of the next sheet, and so forming wire gauze tubes into which sticks of caustic alkali can be inserted, there being narrow straight pieces of wire gauze between the corrugated sheets at the ends thereof. The case is provided on its exterior flat surface, which lies next the wearer, with a -F/G J.---------- --------- IB ■IB ’ r-\ 1 \ V/ 2); ' KfiL / \ ------'FfG.4. /e j|, z. plate of material which does not readily conduct heat, such as asbestos; and according to this invention, upon the opposite side of the case to that just mentioned, a cooling jacket is fitted to contain any well-known cooling liquid medium. The tube from the face-piece conveying the exhaled breath enters the case at one side near the base thereof, and from the opposite side near the top of the case is the tube which conveys the purified nitrogen to the face-piece, and fitted on this case is a pipe which enters the tube conveying the nitrogen, said pipe being connected to the storage of oxygen gas and delivering a jet of the oxygen gas with the usual injector action into the supply pipe to the face-piece. Fig. 1 is a rear elevation of the generator, and fig. 2 is a horizontal section about the line X Y of fig. 1, to show more particularly the arrangement of the wire gauze divisions; fig. 3 is a right-hand end view of the regenerator shown at fig. 1; fig. 4 is a vertical section of the regenerator; and fig. 5 is a sectional detail view showing the entry of the oxygen jet into the supply pipe to the face-piece.

Graham, of St. Andrews Works, Crofton Park-road, Brockley, London. — This invention relates to electric bells, embodying the ordinary hinged lever or equivalent, in which the contacts of the circuit interrupter are enclosed in a watertight manner, the move- ment of the armature being transmitted to the said circuit interrupter through a diaphragm by means capable of fine adjustment from without the watertight casing. The object is to secure greater compactness than has heretofore been possible by enclosing the circuit interrupter in the same casing as the electromagnet and arranging that the contacts thereof shall be separated through the action of the diaphragm due to an impact received by a lever upon the latter from the hinged lever or equivalent when the electromagnet is energised. In this way, except when the y, 771 r bell is ringing, the diaphragm is relieved of strain. Fig. 1 is a front elevation of one form having a gong struck exteriorly ; fig. 2 is a similar view of a similar arrangement in which the gong is adapted to be struck interiorly. (Two claims.)

THE “PROTO (FLPATEN?S,S) RESCUE APPARATUS ------------------------------ IS THE - SAFEST APPARATUS :4. NO INJECTOR EMPLOYED. ALWAYS UNDER POSITIVE PRESSURE, therefore no danger of drawing poisonous air|into breathing circuit. All fatalities that have occurred have been with the Injector type. The “PROTO” has saved lives and an immense amount of property. It has never cost a life.
