Aqueous solutions of alkali metal silicate are hardened using blends of alkylene carbonates and aliphatic alcohols such as alkylene diols, polyalkylene glycols, or hydroxyalkyl ethers. The aliphatic alcohol decreases the set time from that obtained using alkylene carbonate alone. The hardened alkali metal silicate compositions are useful as binders in the preparation of foundry molds or in other a...

Apparatus, and accompanying methods for use therein, for translating virtual page addresses in one address space, e.g. virtual, to page addresses in a second address space, e.g. real, and specifically for increasing the speed of such translations by translating multiple contiguous virtual page addresses upon the occurrence of a miss in a translation lookaside buffer (TLB). In response to a TLB mis...

A transpeptidation reagent comprises an asparagine-residue specific protease. The reagent finds application in a method for producing a peptide by the transpeptidation reaction, which comprises the use of the asparagine-residue specific protease as the catalyst.

An approach that is tailored to a real time processing system receives a set of input samples at each given time interval (frame), and with an IC processor and a relatively small cache memory develops a set of output samples at the same frame interval. The programs that need to be executed in order to develop the output signals are divided into modules that are small enough to fit within the cache...

The present invention provides a microwave irradiating sterilization process in which local irradiation is repeated by means of local heating waveguides being close to the undermentioned package in the case where either such a package charged with a material to be sterilized and then sealed hermetically or a supporting holder containing the package is irradiated with microwave while conveying cont...

A microprogram controller is disclosed, which can receive an interrupt request signal during execution of STRING instruction for transferring character-string or bit string. In the execution of the STRING instruction, a data transmission operation for transferring one unit data of the character-string or bit-string is repeated by a predetermined number of times, and an instruction and signal is pr...

Methods and apparatus are set forth for optimizing the performance of instruction processors using an instruction cache memory in combination with a sequential transfer main memory. According to the invention, the novel memory system stores preselected instructions in cache memory. The instructions are those that immediately follow a branch operation. The purpose of storing these instructions is t...

Medical devices and methods employing semipermeable materials, such as acrylic copolymers, polyurethane isocyanate, and other biocompatible semipermeable polymers, are disclosed for use as guidance channels in regenerating nerves. The devices can be formed by tubular semipermeable conduits adapted to receive the ends of a severed or damaged nerve. The tubular conduits define lumens through which a...
