Abstract: 1,162,322. Casting processes. MONSANTO CHEMICALS Ltd. 4 March, 1968 [31 March, 1967], No. 14824/67. Addition to 1,132,361. Heading B3F. [Also in Division C3] Metal is cast into a block or piece mould containing or surrounded by particulate active C undergoing combustion. The metal may be cast after combustion of C has proceeded long enough for air to be purged from the permeable mould material. The C may be disposed in one or more sealed cavities within the mould, or the mould-body may be sealed into a jacket of vapour-impermeable material, e.g. mild steel, containing the C. The temperature of the mould when brought into association with the C is preferably 750 C., and the metal is preferably cast before the mould temperature drops below 500 C. The C particle size range is preferably 30+150 B.S.S. mesh, and has specific surface area 500 m.<SP>2</SP>g<SP>-1</SP>. The mould may be made by the lost wax process from a slurry of hydrolysed ethyl silicate or silica aquasol and coarse refractory aggregate, e.g. with grading distribution - 30 + 80 mesh 65%, and - 200 mesh, 35%. The mould is dried and then fired, e.g. at 950-1100 C. The metal is normally cast more or less immediately the mould is removed from the firing furnace. If cavities for C are to be provided, fusible patterns for these are placed on a base-plate with the main mould pattern. The metal may be high-chromium steel, or lowcarbon, high-alloy tool steel, or ferritic or martensitic stainless steel. Decarburization of the metal surface is reduced or avoided.

Filed: 1920-06-09
Abstract: 144,669. Soc. Anon. des Etablissements L. Bleriot. Feb. 5,1919, [Convention date]. Heating by electricity.-Heating-elements, for instance, for a flat-iron, are arranged in two pairs to form the arms of a Wheatstone-bridge temperature-controlling device, one pair a being of material such as carbon, boron, or constantan, having a negative or nil temperature, coefficent, and the other pair b of material such as nickel having a positive coefficient; the difference of potential across the points e, f produced by a rise in temperature causes the winding j of an electromagnet to attract an armature k and insert a high resistance l in the circuit or to open the circuit. The magnet may have one or more additional windings in series or shunt with the resistance l to attract the armature when the potential across the points e, f falls owing to the insertion of the resistance. Variations in the reluctance of the electro-magnet may be compensated by means of the resistance i or a part, of it. In another arrangement, the electro-magnet is replaced by a heating-coil and a thermal switch in the form of a bimetallic strip.

Title: Blower with drum-shaped rotor
IPC: F04D17/04
Filed: 1962-04-25
Abstract: 1,000,063. Centrifugal and transverse-flow blowers. T. HELMBOLD. April 25, 1962 [Sept. 11, 1961], No. 15711/62. Heading F1C. In a blower having a drum-shaped rotor provided with a ring of blades and bounded by end discs, the end discs are extended radially on the inlet side of the blade ring in a substantially straight line beyond the blade ring to such an extent that the inflowing fluid enters the region of the blades without flow reversal in the region. In the centrifugal blower shown, comprising a rotor 1 of cylindrical or, as shown, frusto-conical form and having blades 3 extending between end discs 2, the end discs extend radially inwardly beyond the blades, thereby preventing a return flow around the individual blades towards their suction side which otherwise tends to occur in the region of the blade ends. Consequently, the delivery is maintained constant over the axial extent of the blower, giving increased power and reduced noise. As shown, the inward extension of one of the end discs 2 merges into a flared inlet opening through which the air is admitted at 7 in the axial direction. The casing is recessed at 8 and to allow the end discs to be flush with the casing walls. Labyrinth seals 10 may be provided. A transverse-flow blower is described, in which the extension of the end discs beyond the blades occurs in a radially outward direction. The casing part separating the inlet and outlet has slots to receive the radial extensions of the end discs.

Filed: 1947-06-14
Abstract: 637,192. Mechanical toys. GOWLAND, J. P. June 14, 1947, No. 15732. [Class 132 (iii)] A pull-along toy figure has a body or frame to which are attached a number of movable parts, each movable part comprising one or more articulated elements threaded on flexible pull-transmitting supporting members, a handle by which the toy may be pulled along, a number of spring elements attached to said body or frame and each arranged normally to tension different supporting members or groups of such members, and a number of remotecontrol members respectively connected to different spring elements for opposing the tensioning action thereof, the control members extending along the handle and being each provided with separate manipulating means adjacent the outer end of the handle. The control members extending along the handle may be rods or may be flexible, and may be enclosed in a sheath. As shown, a toy dog has a body 10 with a neck 11, comprising one or more bead-like elements to which a head 12 is attached, and a tail 13 and legs 14 and 15 each comprising a number of bead-like elements. These elements, which are strung on cords as shown, may have bulging ends to facilitate articulation. Two. cords 18 are secured to the head 12 and pass through a bore in the head and the bead of the neck, and then separate passing through the body one to each leg. Similarly cords 20 pass through the tail, body and hind legs. The legs are attached to a wheeled base 16 under which there are two levers 22 and 27 to which the cords 18 and 20 are attached respectively. Each lever is pivoted to the base one end of each being held by a tension spring 24 or 29 attached to the base and the other end attached to the cords 18 or 20 to maintain the latter 'under tension. A flexible lead 32 comprises a sheath 33 secured to the base 16 and two inner control members 34 and 35 (cords, wires or the like) attached respectively to the levers 22 and 27 to act in opposition to the springs 24 and 29. Rings are attached as shown to the outer ends of these members by which they are actuated to collapse the various parts of the figure. The members may be attached directly to the springs and cords 18 and 20 thus enabling the levers to be dispensed with, somewhat as shown in Fig. 4. The controlling members and tensioning springs may be housed within the body of a toy animal and in this case also may be arranged with levers as described above or as shown in Fig. 4. A toy horse may have a rider 63 actuated by an additional member 64 and tension spring 67 within its body. The legs, head and tail are constructed as before and actuated by flexible members and springs, also housed in the animal's body and arranged to operate as described above. The whole is controlled by a flexible lead which in this example has three cores. The fore feet and hind feet are joined in pairs by axles, and four wheels 40a are mounted on these axles one being held in a groove in the bead forming each foot. The Provisional Specification describes also a horse and rider mounted on a wheeled base.
