Title: Stove for drying parts such as welding electrodes - with forced air circulation through row of electric heaters
IPC: F27B17/00
Filed: 1974-10-15
Abstract: Stove for the drying of workpieces such as welding electrodes, consisting of a chamber with thermally insulated walls, and hot air is blown through the chamber by a fan. Several groups of electric resistance heaters are located beneath the perforated base of the chamber across its entire widt, and deflector baffles are used so the recycled air flows past all the heaters; and the top of the chamber and at least one of its vertical walls form a channel leading to the fan inlet so that the air can be continuously recirculated. The recycled air pref. flows along a passage with no thermal insulation and fitted with cooling fins for condensn. of moisture in the air, and with one or more drains for this condensate. Uniform air flow past the heaters and therefore a uniform temp. distribution through out the furnace chamber is obtd. The stove can also be used for metal heat treatment or baking enamels.

Title: Conversion of tubular sheet to radiator panels - by selective compression and internal welding of the tubular profile
IPC: B29C49/00
Filed: 1975-01-03
Abstract: Continuous production of flat radiators incorporating transverse passages linking longitudinal circulation passages, by leading a flat but internally pressurised tubular profile between mould tools which can locally pinch and join the profile to define the internal passages. For mfr. of central heating system, using sheathing made either by extrusion of plastic material, or longitudinal welding of sheet metal or plastic material, such as PVC, polystyrene, polyolefin, polycarbonate or poly(phenylene) oxide. More efficient process than traditional assembly of individual side panels. The forming is effected using a series of moulds moving parallel to the profile path. Inserts may be loaded into the profile at intervals to form plugs or spigots in the longitudinal passages. The profile is (automatically) cut to obtain individual panels. The formed sheet may be passed through two successive chambers; in the first the material may be annealed and/or the welds are effected by pressure bars incorporating (electric) heater elements, in the second the profile is chilled.

Title: Synchronous single phase motor controlled valve - has motor switches controlled by end of travel stops on valve member
Inventor: BROE MAX
IPC: F16K31/05
Filed: 1975-01-21
Abstract: A valve operated by a motor has switches to cut motor current when the valve reaches its open or closed position, which is marked by mechanical stops. The motor is single phase and synchronous, with an arbitrary direction of rotation. If the motor starts in the incorrect direction, it will be unable to move the valve due to mechanical stops and will itself change its direction of rotation due to the fact that it does not possess a ratchet. The motor (1) is connected to the valve member (2) in cage (3) my means of a shaft. In the cage two projections (4, 10) serve as stops for the valve-closed position, and an external stop (5) for the valve-open position cooperates with arm (7) which itself acts in conjunction with switches (6, 8). Switch (9) is used to transfer to another supply.

Title: Securing of stator output conductors - uses expanding wedges holding conductors in arch radially supported by lacing
Inventor: BENUCCI BERNARD
IPC: H02K3/50
Filed: 1975-08-07
Abstract: The method of securing the output ends of rectangular cross-section stator conductors is capable of withstanding the high electromagnetic forces acting on the windings as they leave their slots in the stator casing and avoids the consequent damage to insulation. Expanding filling pieces or shims are inserted between stator conductors so that they form a continuous-circular arch. Expansion of the wedge shaped shims in a tangential sense provides a compressive holding force on the arch. The wedging arrangement is held in place by a form of lacing (56) providing a radial force on the shims. Each shim has a movable quoin which produces the tangential force when forced radially.

Title: Blast furnace tuyere with calorized working surfaces - which permit higher wind temp. and reduce coke consumption
IPC: C21B7/16
Filed: 1975-10-09
Abstract: The bore and outside surface of the tuyere are coated by calorizing and the inside surfaces of the cooling jacket may also be calorized if required. The coatings are pref. obtd. by the diffusion of a mixt. of Al and active Al2O3 at 800 degrees C, to form a coating of 0.5-5 mm on the inner and outer surfaces of the tuyere, and 0.1-1 mm on the inside surfaces of the cooling jacket. Prevents the deposition of molten metal and/or slag on the surface of the tuyere and also the erosion of the cooling jacket due to the high velocity of the cooling water. The result is an increase in the working life of the tuyere.

Title: Electric furnace radiant heating assembly - having detachable panels carrying heating elements suspended from brackets
IPC: H05B3/66
Filed: 1976-12-29
Abstract: Several metal brackets are fixed to the walls of an electric furnace to extend horizontally perpendicular to the inner wall of the furnace. Each bracket has at it free inner end a fixing flange from which a suspension rod is hung and fixed by means of a pin passing through the flange and rod. A second pin secures the heating panel that is hung from the lower end of the rod, in such a way that the panel can expand in a plane transverse to the plane of the bracket. Each panel is made up of a frame of vertical uprights welded to horizontal cross ties and has flexible conductors for connecting to other panels or to the supply. Holes with a lining of insulating refractory material are made through the vertical uprights at regular intervals over their height for the support of heating elements that pass through them. Alternatively lots of horizontal parallel rods are welded to the frame at right angles or parallel to its general plane. These rods have a refractory and insulating peripheral coating so the heating element can be looped in sinous form over them. Used in e.g. bell type, open hearth type, etc. electrical furnaces, for heat or chemical treatment in the metallurgical, chemical or petroleum industries. The heating panels can be easily put in position or removed for repair. Avoids problems due to expansion and creep at high temps. Only a thin, light refractory lining is required as the panels favour radiation.
