A phosphate additive, such as apatite or monocalcium phosphate monohydrate, is used to treat concrete aggregate and concrete to improve its resistance to natural and salt induced breakdown. The phosphate can also be used in association with road salt to prevent spalling and breakdown of concrete surfaces and damages to cars. Used alone as a surface treatment, it has the same effect.

Blood is pumped by a pump (24), preferably a biconcave diaphragm pump. When the blood pump is full of blood, this full condition is detected and a batch of blood is emptied completely from the pump for delivery to the patient. A second pump (68), also preferably a bi-concave diaphragm pump, pumps anticoagulant into the blood as it is recovered. This second pump ejects its contents every time the b...

A medical pump device is constructed so that a pulsation force is applied to the blood in the vicinity of an artery, which is reconstructed after a bypassing operation has been completed, so as to compensate for a deviation of an actual wave form of a blood flow in the vicinity of the reconstructed artery from a normal wave form thereof. The medical pump device is capable of minimizing the possibi...

A coating sheet material is provided for wrapping, packaging or shipping food articles that are to be heated in a microwave oven. The sheet is formed from a paper or paperboard backing which is thermally and dimensionally stable when exposed to microwave energy. On at least one surface is provided a smooth supercalendared surface or the sheet is treated by processing as with a filler coating to fi...

An apparatus for heating a food item in a microwave oven is disclosed which has heater regions in combination with a reflective lattice structure. The combination of the reflective lattice structure and heater regions provides a food heating device which substantially maintains its reflectance, absorbance and transmittance during microwave heating. Substantial uniformity of heating is also achieve...

A pipelined CPU employs separate microinstruction pipelines for the execution unit and memory management unit. Deadlocks can occur in a pipelined CPU when there is data dependency in two consecutive instructions. The later instruction may stall the pipeline if operands fetched by an earlier instruction are needed, but the earlier instruction is not producing the memory request for the operands bec...

DIR 0378 The invention relates to an automatic injector for injecting one or more injection liquids, comprising an assembly of a discharge mechanism, a cartridge in a cartridge holder, and an outer sleeve which is telescopically slidable around the cartridge holder, which cartridge comprises a barrel, in the barrel a piston and a number of separating stoppers equal to one less than the number of i...

An improved Schirmer I Tear Test strip is provided. The improvement comprises a conventional filter paper strip having a graduated migration scale printed on the test strip and the presence of a water soluble marker dye e.g. a spot of blue dye, that co-migrates with the tear migration front. Both these features are provided to increase the reproducibility of the test and ease with which the result...

Pref. are (I) where R1, R2 and R8 or R1, R4 and R8 are mycolic acid residues. Cpd...

The present invention is a process for preparing 2'-deoxy-5-trifluoromethyl- beta uridine characterized in that a 5-trifluoromethyl-2,4-bis(triorganosilyloxy)pyrimidine and a 1-halogeno-2-deoxy- alpha -D-erythro-pentofuranose derivative are subjected to condensation reaction in chloroform to give a 1-(2-deoxy- beta -D-erythro-pentofuranoxyl)-5-trifluoromethyluracil derivative which is then subject...

Disaccharide compounds represented by formula (I): wherein R, R<1>, R<2>, R<3>, R<4>, and R<5> are as defined in the specification and salts thereof are disclosed. The compounds exhibit excellent antitumor activity and low toxicity and are useful as antitumor agents.

A process for preparing polyol fatty acid polyesters, e.g. sucrose polyesters (SPE) is improved by (1) mixing the polyol with an alkaline catalyst such as KOH, NaOH or their carbonates, preferably in aqueous solution or dissolved in C1-5 alcohols or ketones at atmospheric pressure and 10-80 DEG C, (2) preparing a mixture of fatty acid lower alkyl esters with an emulsifier, preferably a fatty aci...

An improved packaged semiconductor device is provided having an electronic component, such as an integrated circuit, enclosed within a single layer ceramic PGA package. A cap, of substantially the same areal dimension as the base, is sealed to the base forming a cavity in which the integrated circuit is mounted. Input/output pins are attached to through-holes in the base and extend through the bas...

A modular fail-safe memory and an address generation mechanism that provides load balancing when the memory is shared by a number of processors (320). A plurality of memory modules (10a-m) are used for the memory with no specific limit on the number of memory modules, and a checksum block is used to back-up corresponding blocks in the other memory modules. The checksum blocks are distributed acros...
