Title: Safety devices for oil burners
IPC: F23D11/00
Filed: 1965-05-11
Abstract: 1,062,162. Burners. BABCOCK & WILCOX CO. May 11, 1965 [June 2, 1964], No. 19897/65, Heading F4T. An oil burner is removably secured to a housing 10 on the front of a boiler and two valves (23), Figs. 3, 4, 5, 6 (not shown), for oil and atomizing steam are disposed in the housing 10 and are opened against spring pressure by a control rod 15 which is moved axially and rotatively by a handle 16 guided by a bayonet slot (14a, 14b), Fig. 3 (not shown), a latch 51 qn the housing, a pin 48 on the burner and the control rod 15 co-operating so that the valves cannot be opened after the burner is withdrawn and the burner cannot be withdrawn whilst the valves are open. When the burner is withdrawn a finger 51b on the latch is pressed by a spring-actuated plug 55 into a slot 15d in the control rod 15 so that longitudinal movement of the rod 15 is prevented. On inserting the burner the pin 48 slides through an arcuate notch (15e) on the control rod and disengages the finger of the latch from the slot in the control rod. The latter can now be moved longitudinally, the handle 16 passing along the first part of the bayonet slot, and a solid portion of the control rod enters an arcuate notch 48a in the pin 48 to lock the burner. The control rod also has cam surfaces (15a, 15b), Fig. 9 (not shown), and when the handle 16 is moved in the second part of the bayonet slot the control rod is rotated and the cam surfaces open the oil and steam valves. The passages in the housing for oil and steam terminate in bevelled bushings (31) carrying O-rings (32), Figs. 5, 6 (not shown), and adapted to engage with sleeves in the ends of oil and steam channels in the burner. The burner comprises an outer oil tube 37 and an inner steam tube 39. The opening 11a between the burner and valve housing is closed by a spring-urged washer 57.

Abstract: 961,858. Stacking and nesting trays. W. H. LOCKWOOD. June 5, 1961 [June 13, 1960], No. 20143/61. Headings B8D and B8P. Open-top nestable trays with peripheral flanges have interengaging projections, e.g. 18 and recesses, e.g. 19 on the flanges so that when one tray is inverted and placed upon another a closed receptacle is formed, the bases of the trays having similar projections and recesses so that the receptacles so formed can be stacked. In one form, a square tray 12 has a peripheral flange 17, Fig. 1, with staggered projections 18 so arranged that when an identical tray is inverted and placed on the tray to form a closed receptacle 10, Fig. 5, the projections 18 on one tray engage in the spaces 19 on the other. The bottom surface of each tray has similar exterior projections 21 so that the closed receptacles so formed can be stacked one upon the other. The empty trays can be nested in the ordinary way since the sides slope outwardly. Fig. 9 shows a modification in which the projections are replaced by hook-like members 36, 40 and the engagement is effected by a relative horizontal twisting movement of the trays. When the hook members 36 are fully engaged, a rib 43c engages a depression 43d to retain the inverted tray in place. Triangularsection display trays 51, Fig. 20, can be formed into closed receptacles by snapping resilient hooks 64 over hook-receiving portions 65 and engaging portions 63b, 63c on the sides. Hooklike members 60 on the tray bottoms are slid together to stack the closed receptacles. The trays may be moulded of plastics or made of metal, wire mesh or plywood.

Filed: 1927-08-04
Abstract: 300,184. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). Aug. 4, 1927. Hydrochloric acid; sodium bicarbonate.-Clay, phonolite, leucite, &c. are treated with sulphuric acid, or a mixture of sulphuric and hydrochloric acids. After separating insoluble matter, the solution is evaporated with an amount of sodium chloride equivalent to the sulphuric acid, and the residue is heated to 700‹ C., preferably in a rotary furnace in which the materials and the heating gases pass in the same direction. Hydrochloric acid is evolved. The sintered product is heated to 1000‹ C. with carbon to produce sodium sulphide, sodium aluminate and some soda. The product is lixiviated. Some of sodium sulphide may be separated by crystallization, and alumina is precipitated by treatment with sulphuretted hydrogen or carbon dioxide, or a mixture of these gases. Further quantities of sodium sulphide may be separated by crystallization. The mother liquor, or the liquor before separation of sodium sulphide may be treated with carbon dioxide to separate sodium bicarbonate. If the clay &c. has been treated mainly with hydrochloric acid, alkali sulphate may be added to the sintered product, and if only small amounts of hydrochloric acid have been used, bauxite may be added in order that the sintered mass may contain about equimolecular proportions of alumina and sodium sulphate.

A gas-tight alkaline accumulator casing is divided into cell compartments by electrically conducting partitions whose outer parts are embedded in the casing and each compartment encloses a pair of electrodes whose edges are covered with a layer of ion- and gas-impermeable synthetic material, e.g. epoxy resin. The layer of synthetic material preferably constitutes an integral part of the accumulator casing. Thus to form the accumulator shown, metal powder is sintered to the ends of the metal partition sheets 9 and epoxy resin is melted into the sintered edge. The partitions are then assembled under pressure between terminal plates 10, 11 with anodes 6, separators 7 and cathodes 8. Core pins 12 are positioned to contact each separator 7 and epoxy resin is spread over top and bottom of the electrode block to form layers 5 which embed the ends of the partition sheets and contact the edges of the electrodes. The core pins are then removed to leave holes 13 through which the cell is evacuated and filled with electrolyte. The cell is then overcharged to expel excess electrolyte and the holes 13 are sealed with resin. An outer casing e.g. of aluminium or aluminium alloy may be cast or formed around the casing or the casing may be wrapped with steel banding. The resin used may contain shale or slate dust, glass powder or basalt fibres as a filler. The separators may be of " Perlon " or a polyamide filter paper. The cells may also be cylindrical and mounted coaxially.
