Title: Solidification microstructure of aggregate molded shaped castings
Inventor: GRASSI JOHN R
IPC: B22D25/00
Filed: 2007-08-14
Abstract: A shaped metal casting made in an aggregate mold comprises fine solidification microstructure that is finer than the solidification microstructure of an analogous metal casting made from conventional molding processes. The solidification microstructure may be up to five times finer than the solidification microstructure of a conventionally prepared casting. In preferred embodiments, as a result of directional solidification, the fine solidification microstructure is substantially continuous from a distal end of the casting to a proximal end of the casting, and exhibits greatly enhanced soundness. Because of the control of the uniformity of freezing of the casting, its properties are substantially uniform.

Title: SONET/SDH network element with ring cross connection with path selection in switch fabric and alarm detection/setting in interface card
Inventor: AZUMI RYOJI
IPC: H04L12/437
Filed: 2009-10-22
Abstract: A SONET/SDH ring network element comprises interface cards 21-1/4 and work/protection switching fabrics 23/24. Input signals are fed through framer 31 which detects 31 alarm conditions on the line in the line card. They then pass through switching section 41-46 and transport overhead TOH inserter 47 and back to the line card. The service selector decides which of work/protection inputs to forward to the output based upon alarm/quality information. Depending upon the selection made routing information protocol (RIP) data is adjusted 49 and inserted in the TOH. Back in the line card selection between work and protection fabrics 37 is performed and the TOH drop function feeds RIP data to controller 33. Depending upon the information supplied the controller 33 feeds alarm settings 34/35 to the alarm detector 32, which applies them to incoming signals. The invention allows alarm detection to be offloaded from the switch fabric to the interface cards.

Title: Processor and prefetch support program
Inventor: TOYOSHIMA TAKASHI
IPC: G06F12/08
Filed: 2007-06-18
Abstract: When a processor detects a register update instruction, it registers an address of the register update instruction in a register producer table corresponding to identification information of the register to be updated. When the processor detects an instruction to access the address indirectly assigned by the register, it identifies the address of the register update instruction registered in the register producer table by the identification information of the register which assigned the address. The processor regards the register update instruction of the identified address as an address generation instruction. The processor prefetches data of the address indicated by the register value updated by the address generation instruction to a cache memory.

Title: Improvements in or relating to measuring or gauging instruments
Filed: 1919-04-23
Abstract: 147,987. Landon, J. W., and Barker, A. W. April 23, 1919. Indicating.-Extensometers, micrometer screw gauges, and other instruments required to measure under conditions of uniform pressure, are provided with a yielding means, employed to obtain uniformity of resistance in the touch or to give a magnified indication of a departure therefrom. Fig. 1 shows the application to an extensometer whereof two levers B, B<1> are attached by centre points to a test piece A, and are separated by a strut F providing at each end a fulcrum for one of the levers. The distance apart of the outer ends of the levers is measured by means of a system of guide rods L, with micrometer screw adjustment M, P, graduated for the effective length of the test-bar, which acts against the attractive force of a spring S, and a part of this system consists in the yielding-means referred to. In the form shown they consist of two long narrow strips of metal G, mounted at their ends in blocks G', G<2> which bear the lever-contracting members H, M', and when the micrometer screw is adjusted for normal tension of the spring S they are very slightly bowed, fiduciary marks upon two blocks G<3> attached to the midpoints of the strips being very slightly displaced. The strips, or equivalent members, must be such that small relative movements of their ends in the direction of their length produce large movements of the blocks. A cover R with inspection opening R' is provided. By suitable connexions the movement may be still more magnified by use of two such sets of strip in series. Scales carried by the mid-point blocks may give a direct indication of the movement of the ends, or these may be indicative by optical means.

Abstract: 793,955. Cutting-apparatus. SPICERS, Ltd. March 26, 1956 [April 7, 1955], No. 10276/55. Class 31 (1). [Also in Group XVI] A method of producing envelope blanks A, Fig. 2, comprises feeding a web of paper W past cutter means to form at least two longitudinal rows of blanks arranged side-by-side, each blank having end flaps B, C which at the adjacent sides of adjacent rows are interspaced with one another in such a manner that the opposite lateral edges F, G of adjacent end flaps are spaced from one another whilst the longitudinal edge of an end flap is coincident with an opposing longitudinal edge portion of the adjacent row of blanks. As shown in Fig. 3, a web of paper W is fed between a rotatable anvil roller 5 and cutter means rotatable about an axis 7 which cut from the web four rows of envelope blanks, as shown in Fig. 2. After leaving the cutter means, adjacent rows of blanks are separated by being directed alternately round upper and lower rollers 8, each separated row being passed to cutters 12, 13 which sever the blanks of the row along lines K, Fig. 2. The blanks are then fed past suction rollers 16 and stacked. The rows of blanks are cut from the web by means of separate rotary cutters 21 to 25, Fig. 4. Each rotary cutter is supported by a pair of pivotally-mounted bellcrank levers 27, Fig. 3, and is urged into contact with the web by means of an adjustably-loaded spring 33. The anvil roller 5 and rotary cutters are driven by common driving means. The periphery of each of the cutters 22, 24 is formed to provide a cutting edge consisting of two spaced arcuate portions 49, 50, Fig. 7, interconnected by cutting edges 51. The portions 49, 50 cut the web along the lines H, Fig. 2, whilst the edges 51 cut the web to produce the apertures defined by edges F, F<SP>1</SP>, G, G<SP>1</SP> constituting waste material which is ejected by means of rubber plugs 52, Fig. 5. The remaining paper waste which is cut out of the web is preferably removed by blowing or suction through holes in the anvil roller or in the rotary cutters.

Title: Magnesia composition and method of making same
IPC: C04B35/03
Filed: 1960-03-25
Abstract: A slip-cast high-density refractory article is made by mixing a fused or high calcined (i.e. at at least Orton cone 8-2237 DEG  F.) magnesia of at least 98% purity with not more than 1% titania, preferably 0.05-0.5%, forming a casting slip from the mix, slip-casting the desired shape, and firing to at least cone 18 (2705 DEG  F.) preferably at cone 30 (3002 DEG  F.). The bodies thus prepared show less shrinkage on firing, have a lower porosity and higher density (up to 3.5), and a higher modulus of rupture than bodies prepared under the same conditions but in the absence of titania.  In an example, magnesia and titania were mixed with water and a milling medium, and milled for 10 hours before being slip-cast and fired.
