摘要:
Acidic, thickened cleaning and disinfecting compositions which exhibit good long term shelf stability, are particularly effective in the removal of limescale from hard surfaces, and which are effective against gram positive and gram negative bacteria. The compositions comprise one or more nonionic surfactants; one or more quaternary ammonium surfactant compounds having germicidal properties; an acid mixture comprising formic acid and one or more water soluble organic acids, particularly water soluble organic acids selected from the group consisting of: lactic acid, citric acid, glycolic acid and where the formic acid and one or more water soluble organic acids are present in a weight ratio of formic acid: formic acid:water soluble organic acid(s) of 1:0.1-10; a cellulose based thickening composition; optionally but desirably a one or more conventional additives such as a coloring agent, fragrance or pH adjusting agent; and, water. The compositions may also include further conventional adjuvants such as perfumes and coloring agents in minor amounts. The compositions feature surprisingly good viscosity retention over time notwithstanding the presence of formic acid and cellulose based thickeners in the compositions.
摘要:
Aqueous disinfecting and cleaning compositions and concentrates which are efficacious against gram positive and gram negative bacteria, have relatively low volatile organic content ("VOC") and are surprisingly mild to the user of the compositions. The compositions include a quaternary ammonium compound as its primary germicidal active agent, have a low content of active constituents, and do not include organic solvents such as alcohols, glycols, or glycol ethers in significant amounts.

A system and method for generating test cases for a computer program. The method and system include invoking execution of the computer program via a remote client and monitoring the execution of the computer program. Information about execution path of the computer program is collected and then the execution of the computer program is stopped via the remote client. One or more test cases are then generated utilizing the collected information. In one embodiment, the remote client is a computer test tool and the computer program is a web application.

The invention includes superconducting titanium-containing compositions having less than 200 ppm, by weight, of a combined total of interstitial materials selected from the group consisting of nitrogen, oxygen, carbon and hydrogen. The invention also includes methods of forming superconducting titanium-containing superconducting compositions containing less than 100 ppm, by weight, of a combined total of interstitial materials selected from the group consisting of nitrogen, oxygen, carbon and hydrogen.
摘要:
A waterpouring system and method for use with a multiple-input, multiple-output (MIMO) transmitter. In one embodiment, the waterpouring system includes an encoding decision subsystem that selects a constellation combination based on gains in channels of the MIMO transmitter, and a vector modulator subsystem, coupled to the encoding decision system, that modulates a fixed number of bits in a bitstream with the constellation combination to generate a symbol vector. The waterpouring system also includes a normalization and precoding subsystem, coupled to the vector modulator subsystem, that weights the symbol vector based on the gains to yield a weighted symbol vector and distributes the weighted symbol vector among the channels.

摘要:
Apparatus including a disintegrating head and a mixing head each having a stator and a co-operating rotor. The rotors are mounted at axially spaced locations on a common shaft and the stators are supported with the inlet to each stator facing axially of the shaft, away from the other stator. The disintegrating head has a stator formed of a plurality of stator elements arranged at angulary spaced locations on a base member. Each stator element has a cutting edge which is inclined outwardly of the element in a direction away from the base member. Associated with the disintegrating head is a shroud which serves to retain large lumps of material in the vicinity of the head.
