Abstract: A tire mold and method for producing vent holes therein comprising placing metal tubing in the desired locations on a female core for producing the tire mold, which after the casting metal is poured onto the core, encompasses the metal tubing leaving a vent hole in the metal of the tire mold at the respective tubing, after which the core material is removed. This eliminates conventional practice of drilling vent holes in a tire mold and provides for vent holes in areas heretofore inaccessible.

Abstract: Radiator particularly for blast furnaces has a shape of plate and outer box 1 made of cast iron with 1% addition of chromium. Inside outer wall of the box there is installed a cooling coil 2. From the interior the radiator is provided with a lining of semi-graphite sections.Method of production of the radiator consists in preparing a form of cement mix for casting the box in a floor by using a model, after hardening mold cavity is spreaded with a protective coating, preferably water-graphite one and after the mold is dried there are placed semi-graphite sections. To the top portion of the form, made of chamotte mass, there is fixed a cooling coil and the whole form is filled with cast iron by the hitherto applied method. For cast iron there is used the addition of 1% of chromium, being introduced in a form of self-meltable ferrochromium preferably into the vat.

Abstract: A method of forming the core tube of an electro-magnetic solenoid comprises forming and positioning the end portions of the core tube and centrifugally casting the non-magnetic intermediate portion of the core tube.

Abstract: A method of attaching an end frame and another structural component of a dynamoelectric machine wherein the structural component is positioned within a receiving means therefor in the end frame. At least one of the end frame and structural component is moved relative to the other thereof to an aligned position for assembly with each other, and metal is cast into the receiving means for forming a rigid tie between the end frame and the structural component for maintaining them in their aligned assembly position. Apparatus for rigidly interconnecting an end frame with another structural component of a dynamoelectric machine is also disclosed.

Abstract: A process for forming a composite material comprising a metal matrix incorporating fibrous reinforcement having a pre-determined pattern of fibre orientation which includes the steps of providing in a mould substantially parallel fibre arrays in which each array consists of a sheet of substantially coplanar fibres, providing a reservoir of molten matrix metal between at least some of the fibre arrays and applying pressure to the mould contents sufficient to force molten metal to surround substantially all the fibres.

Abstract: Manufacturing process for a solid or hollow shaft consisting of aluminum or itanium with beryllium reinforcing therein. Beryllium rods are either clad with aluminum or titanium or, in the alternative, holes are drilled in an aluminum or titanium block which beryllium material is thereafter inserted into the holes. The preform with a hard steel central mandrel around which the beryllium rods are positioned is placed within a steel can and heated to a predetermined temperature. Pressure is then uniformly applied to outer circumference of the can to ensure uniform deformation of the beryllium reinforcement. The uniform exterior pressure on the outer surfaces of the beryllium rods and the interior pressure on these rods caused by the hard steel mandrel against the under surfaces of the rods as a result of a reduction process causes the beryllium rods to assume an arcuate ribbon configuration. For hollow shafting, the mandrel at the center of the preform may later be removed.
