Granted: 1991-07-23
Abstract: ABSTRACT           A method for the manufacture of a mold out of mold material from a previous blank by machining each blank into a desired shape by means of a machine tool controlled by a computer utilizing a dimensioning data set.  Each blank is manufactured by feeding an organic polymer material whose melting point is preferably lower than 150°C. in liquid form into a box-shaped container which is open at the top and which corresponds to the dimensions of the desired mold.  Waste polymer material from the blank upon machining is recovered and heated to a temperature higher than its melting point, whereupon it is fed onto an existing mold no longer needed, so as to provide a new blank for a new mold.

Title: Internal pipe clamp for inert gas welding
Inventor: WARD GERALD W
IPC: B23K37/06
Filed: 1986-03-03
Granted: 1991-12-24
Abstract: Abstract:   An internal pipe clamp is disclosed which has integral seals for providing an enclosed volume within the abutting pipe sections to be welded.  The oxygen can be purged from the enclosed volume to provide an inert atmosphere at the weld site for an improved weld with alloys such as stainless steel.  The internal pipe clamp is preferrably employed with a pulse MIG welding technique and greatly decreases the time necessary to prepare and weld abutting pipe sections.  The seals in their relaxed state permits the clamp to be moved freely within the pipes.  When inflated, the seals deform to seal between the inner surface of a pipe and the frame of the clamp to isolate the enclosed volume.

Title: Method of cooling hot-rolled steel plate
Inventor: UEKAJI HIROSHI
IPC: B21B37/44
Filed: 1986-12-17
Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE         A method of water cooling a hot-rolled steel plate is disclosed.  In this method, while a hot-rolled steel plate is being advanced lengthwise, a plurality of nozzles spray cooling water to the steel plate, and thus the plate is cooled to a predetermined temperature at a predetermined cooling rate.  Before, while and after the plurality of nozzles carry out water-cooling, temperatures are consistently measured at predetermined temperature measurement points in cross-sectional areas of temperature measurement positions which are arranged lengthwise at predetermined locations of the steel plate.  Each time such measure-ment is performed, degree of deformation of the plate is calculated on the basis of temperature differences between the temperature measurement points.          When the calculated degree of deformation is not within an allowable range, corrections are made on the distri-bution of the water supplied by the plurality of nozzles.

Granted: 1991-04-09
Abstract: Abstract of the Disclosure The invention comprises a chair for cutting children's hair.          The chair has a base portion and a hydraulic cylinder and piston with the cylinder mounted to the base to hydrauically raise and lower the piston. A platform having a series of steps of different heights is mounted to the top of the piston and an animated object is mounted on the platform. The platform has steps on each side or the object. The platform has a central saddle portion for a child to sit astride with its legs straddling on each side of the object. The platform is a conven-ient distance below the object so that a child may rest its feet on each side of the object on a selected step of the platform, depending on the size of the child, to brace and balance the child and to provide stabil-ity to the child on the object so that the child may with less effort remain upright in the saddle straddling the object without a head and back rest and and to make it easier for the child to remain relatively still with less movement either to the side or front or rear thereby making it easier to cut the child's hair and the lack of a head or back rest or side support makes the child's hair more accessable for cutting.

Granted: 1992-02-25
Abstract: CONTROLLED DYNAMIC LOAD BALANCING    FOR A MULTIPROCESSOR SYSTEM            Abstract An apparatus for allowing a system administrator, application programmer, and/or program user to adjust the processor assignment function in a multiprocessor system. The system administrator controls the assignment function by defining certain system variables and flags. The application programmer can adjust the assignment function by causing allocation parameters to be passed in a system call before execution of the assignment function. To adjust the assignment function, the program user executes a system command that inserts similar allocation parameters into the program object code file stored in a file system on the multiprocessor system. The program executing the assignment function is responsive to the system variables and flags as well as the allocation parameters and performs the assignment function as it has been adjusted on a system, program or user level basis.

Abstract: Abstract Of The Disclosure A thermally-tempered, cold curved panel having a sheet of glass, including a resiliently-flexed curvature, and a frame which is adapted to maintain the curvature of the sheet of glass under constraint, as well as a method and a device for producing the curved panel, is disclosed.  The frame of the panel includes straight frame sections and curved frame sections which are secured to the sheet of glass, retaining the curvature of the sheet of glass under constraint.  The sheet of glass is thermally-tempered being cold-curved at a temperature being between 80°C and 140°C, such that a resiliently-flexed curvature is formed therein.  The curvature is maintained under constraint by a special device while the frame is assembled about the edges of the glass.  Once assembled, the frame maintains the curvature of the thermally-tempered sheet of glass under constraint.  The device which permits curving is a template having an upper curving surface having substantially the same curvature as that desired for the final product.  Suction discs, carried by jacks are secured to parts of the glass not contacting the curving surface. Movement of the jacks with the suction discs carried thereon provide the force for the curving operation.
