IPC: F24B1/183
Filed: 1962-01-16
Abstract: 956,078. Hot-water boilers; hoppers for stoves; grates. C. A. FELL. April 16, 1963 [Jan. 16, 1962], No. 1524/62. Headings F4A and F4W. In water heating apparatus comprising a boiler and a firegrate below and at the front of the boiler, the boiler is disposed within and spaced from a substantially rectangular section flue casing, and has a water compartment with a plurality of downwardly extending legs, there being a baffle between adjacent legs to form uptake and downtake flues for heating said legs, the baffles forming part of the flue casing the lower front part of which is open to the firegrate and the top having an outlet flue. In the form shown a boiler 1 is disposed in a rectangular section flue casing 3 and has a plurality of downwardly extending legs 4. Fuel for the grate 2 is gravity-fed from a hopper 19 having its lower end open, the fuel inside the hopper being supported by the fuel burning on the grate. The hopper may be raised or lowered by a rope 20 to give a larger or smaller fire and the upper end of the hopper is closed to prevent the burning of the fuel therein. A collar 23 in spaced relation to the hopper creates a cooling air space on three sides of the hopper. The grate 2, pivoted at 11, can be rocked by a support 16 for ash removal, whilst the front is fitted with adjustable louvres 25. The combustion gases pass upwardly and downwardly between each pair of adjacent legs in turn around the baffles 5 between the legs before passing to the outlet flue 8. Water enters the boiler at inlet 9 and leaves by outlet 10, the latter containing a thermostatic control for an outlet damper 22 which can also be controlled manually. A scraper device 18 is movable by external manipulation between the boiler legs 4 to clear soot from the legs and the baffles 5. In a modification a plurality of boilers can be mounted side-by-side for increasing the capacity of the apparatus.

Inventor: BUCHHOLD THEODOR ADAM
IPC: H01F6/06
Filed: 1960-01-15
Abstract: 906,439. Magnetic bearings. GENERAL ELECTRIC CO. Jan. 15, 1960, No. 1562/60. Class 12 (1). [Also in Groups XXXV and XXXVII] A dynamo - electric machine (see Group XXXV) has a hollow, cylindrical rotor 12 supported entirely magnetically, the rotor and the supporting field coils being made of superconducting material, e.g. niobium, and maintained at a suitable temperature, i.e. close to absolute zero. The rotor has an internal flange 40 on either side of which are coils 44, 46 while further sets of coils 43, 45 face the internal wall of the rotor to provide lateral stabilizing forces. The action is based on the fact that magnetic flux cannot penetrate a superconductor so that if a part of the rotor approaches a particular coil magnetic " pressure " is exerted to restore it to an equilibrium position. In an alternative arrangement (Fig. 8, not shown), the coils are disposed on the outside of a closed cylindrical rotor.

Title: Improvements in process and apparatus for bending and tempering glass sheets
IPC: C03B35/20
Filed: 1938-01-20
Abstract: 509,775. Bending and tempering glass sheets. STEVENS, A. H. (Pittsburgh Plate Glass Co.). Jan. 20, 1938, No. 1921. [Class 56] A method of bending and hardening a glass sheet consists in suspending the sheet in a vertical position from its upper edge, heating the sheet until the glass is plastic, applying. curved pressing-elements to both surfaces of the sheet, and then chilling the glass by an air blast while still held by the pressing-elements. The sheet 41, Fig. 9, is suspended from a bar 31 either directly or through the interposition of a metal sheet 39. The bar 31 is supported by an endless chain conveyer and is carried by it through a tunnel kiln. The glass sheet when hot and plastic is gripped between pressing- plates 43, 45 and bent to the required curvature. These plates 43, 45 slide through slots in the wall of the kiln and are moved to and from one another by levers oscillated by a motor. The plate 39, when used, is also bent by pressing- plates 42, 44, and when so bent keeps the glass sheet in the bent position while it continues to move through the kiln during the annealing period. When the glass sheets are to be hardened or tempered, pressing devices in the form of grids 79, Fig. 10, are carried by casings 62, Fig. 4, which are mounted on trucks 64. These trucks are moved to and from one another by a screw 67 driven by a motor 70 through a slipping-clutch 71. The blowers 62, 63 are provided with nozzles 84 which are adjustable horizontally so that their forward ends can be made to conform to the shape of the bent sheet. Air is supplied to the nozzles by fans 74 through trunks 78.

Abstract: 1,241,591. Chromizing steel strip. ALBRIGHT & WILSON Ltd. Jan. 10, 1969 [Jan. 12, 1968], No. 1938/68. Headings C7D and C7F. Steel strip is chromized by compacting on the strip a powder containing Cr and 1À5-20% by weight of at least one of Si, Al, Mo, Nb, V, Ti and P, heating in a halide containing atmosphere to effect diffusion of Cr and then cold rolling the strip. The steel strip is up to 0À25" thick and preferably 0À03-0À18". The Cr containing powder is applied to give more than 11 gms and preferably 16-20 gms Cr per sq. ft. of strip and the additives are preferably added as alloys with Fe. The powders are minus 100 B. S. mesh and preferably minus 200 B. S. mesh and compaction is effected by rolling at 7 tons/linear inch. Diffusion is effected at above 800‹C. preferably at 920-1000‹C. in hydrogen or an inert gas plus a halide e.g. HCl. If the strip is heat-treated as a closed coil it is preferable to apply a ferrous halide or other halide which produces ferrous halide by reaction, to the compacted Cr containing powder. Ammonium halide may also be applied with the ferrous halide. Final cold rolling effects a reduction of 30-80% and the strip may then be annealed.

Abstract: 469,413. Actuation of switches; latching switches. BRITISH THOMSONHOUSTON CO., Ltd., and NICHOLSON, H. E. Jan. 24, 1936, No. 2322. [Class 38 (v)] The operating- and switch - shafts A, B respectively carry cranks C, F, which are interconnected by a toggle D, E, the common pivot G of which is linked at H to a crank J on an auxiliary shaft K. With the latter stationary, operation of A moves the parts C ... F to the broken-line position, so rotating B to its opposite limiting position. If now the shaft K is rotated clockwise, the toggle is straightened and a further clockwise rotation of B is obtained, as shown chain-dotted. In the application to a bus-bar selector, the limiting positions of the shaft A correspond to the two selecting positions, and operation of K produces further movement of B to an earthing position. Locking discs L, M on shafts A, K have cut-away edges whereby operation of K to earthing position can only take place when A has been operated to move B to the broken-line position, whereas when K is operated to earthing position and its cut-away part is in the chain-dotted position, operation of A is prevented.

Title: Treating infectious diseases in animals
IPC: A61K39/12
Filed: 1963-01-22
Abstract: A method of making an animal resistant to an infectious virus, or other pathogenic microorganism to which the animal is susceptible comprises inoculating the animal with a live heterotypic virus or other microorganism immunologically unrelated to the infections virus or other pathogenic microorganism, said heterotypic microorganism being alien to said animal i.e. produces no sign of illness in the animal and being characterised by its ability to develop complement-fixing antibodies in the animal against the pathogenic microorganism. Thus, live human adenovirus protects dogs against infectious canine hepatitis virus; live bovine virus diarrhea virus protects pigs against hog cholera virus; live bovine rhinotracheitis protects horses against infections equine rhinopneumonitis; live mink enteritis protects cats against feline panleukopenia; live Miyagawanella bovis virus protects cats against infections Miyaga-wanella felis; live Leptospira pomona protects dogs against Leptospira canicola; live hog cholera virus protects cows against infectious diarrhea virus; and live measles virus protects dogs against canine distemper virus.
