摘要： A method of manufacturing brake drums or the like and apparatus therefor that minimizes scrap rates by improving as-manufactured balance. In accordance with the disclosed method, the casting rim of the brake drum is located in a press by centering the drum relative to its outer surface. Locating holes are then accurately formed in the drum center by the press prior to machining of the drum inner surface. The subsequent machining operation on the drum inner surface is accomplished by locating the drum accurately via the locating holes formed in the press operation.

摘要： An improvement in a method of forming a multi-way valve porting block for a mixing valve having a control head and respective conduits for hot water, cold water and controlled water characterized by the steps of: cutting off a predetermined thickness of a metallic bar stock having the desired cross sectional shape with a plurality of arms extending radially outwardly at 90* angles from a central point to form a solid block of the desired shape; and, thereafter, forming by machining respective large bores and smaller apertures in the respective conduits. The bar stock may have a Tee-shaped cross section or a cross-shaped cross section for respective three-way and four-way valve porting blocks, such as for tub alone or both tub and shower. Also disclosed are specific approaches to forming an aspirating passageway and aperture in the arm that will be connected with the tub or the like to prevent water from undesirably flowing upwardly and out of a shower, as well as the respective types of machining operations and preferred structural forms.

摘要： A method for machining contact lenses of flexible material such as silicone. The lens is centered on two rotary spindles of which one is a driving spindle and is clamped therebetween. An annular supporting member having a surface with the same curvature as the face of the lens maintains the shape of the flexible lens during rotation of the lens until it is hardened by the spraying of a jet of cooling fluid which may be liquid nitrogen or liquid air. The spraying of the lens continues while the diameter is reduced, if such reduction is necessary. The supporting member is then removed and the peripheral edge of the lens is machined.

摘要： Male and female members are matched and fitted together in order to remove any protuberances. The die members are mounted in a vibrating machine where the matching surface of one die member is chemically treated with an active solution such as copper sulfate to chemically alter the matching surface to a predetermined depth. Abrasive grains or grits are also interposed in the solution between the matching surfaces of the die members. The relative movement between the die members caused by the vibration of the machine results in the abrasive grains scratching the chemically altered surface at the points or areas of contact. Thus by mechanically abrading and chemically altering such areas an extremely high-quality level of tool and die spotting or matching is obtained.

摘要： A METHOD OF FORMING AN IRREGULAR SHAPED CAVITY IN A METALLIC MEMBER INCLUDES THE STEPS OF DRILLING A HOLE IN THE MEMBER. A RELATIVELY LARGE PUNCH IS THEN INSERTED INTO THE DRILLED HOLE TO EXPAND THE HOLE WHILE THE METAL MEMBER IS SUBJECTED TO HEAT. AFTER THE MEMBER IS COOLED, A SECOND PUNCH, CONFORMING IN SIZE AND SHAPE TO THE CAVITY TO BE FORMED, IS INSERTED INTO THE EXPANDED HOLE. THE MEMBER IS THEN COMPRESSED AROUND THE SECOND PUNCH TO CAUSE THE HOLE TO CONFORM TO THE SIZE AND SHAPE OF THE SECOND PUNCH.
