A test strip is provided for having liquid applied thereto and for determining the presence or quantity of an analyte in such liquid. Specifically, the test strip comprises a reaction zone which varies in reflectance as a function of the quantity of analtye present in the applied liquid. The strip is to be inserted into an optical reading apparatus. A standard zone is positioned on the strip so as...

It has now been found that the use of inert gases as an auxiliary blowing agent in flexible polyurethane foams places unexpected requirements on the composition of the silicone surfactants used in such foams. Typical silicone polyalkylene oxide polyether copolymer comb-type surfactants containing greater than about 37% ethylene oxide in the pendant polyether chains cause large cells when added ine...

Assuming that modules (SC160 to SC163) are combined into assemblies (SSM16B), registers (RCHID), which can be read from and written to via the data bus (DB) to which the modules are connected, are provided for each module, and the addresses of the relevant component and the relevant module are written to them. Also assuming that, if a component is not connected to the data bus, voltage values whic...

A system and corresponding method for enhancing hygiene in a food handling environment include an indicator to be worn by a worker in the food handling area, an activating device located outside of the food handling area, a hand cleaning station located proximate or within the food handling area (remote from the restroom), and a deactivating device operatively associated with the hand cleaning sta...

The invention relates to a method and device for producing soft solder powder without pressure, in particular for producing spherical fine metal particles having a grain size ranging from 1-100 microns and a liquidus temperature <250 degrees C. The method comprises: a) gravity feeding melted solder into an oil receiver while setting a volume ratio of melted solder to oil to at least 10:1; b) dispe...

A process for preparing a cellular polymer containing perforated cell windows in the presence of a perforating agent being a substance that has a critical surface free energy of less than about 23 mj/m2 is disclosed. The cellular polymers obtained according to this invention have a fine cell structure and show enhanced dimensional and thermal insulation stability. The invention also relates to rig...

The device has an illumination source (1) and a CCD camera (8) positioned on opposite sides of the examined plastics sheet or foil (6), for simultaneous detection of light-absorbing and light-deflecting flaws in the material of the sheet or foil. The illumination source has a light dispersion disc (2) on the side facing the plastics sheet or foil, with a material strip (4) for reducing the light i...

A device is disclosed which provides direct and effective incorporation of material (such as medicine) from a separate container into the contents of a liquid dispensing device. The device has a hollow sleeve extending outwardly, an openable closure, a securing member which engages a mating member on the container, and a conduit (such as a needle) to provide fluid communication between the device ...

A method for the accurate formation of a three-dimensional article comprises providing a supply of substantially uniform size droplets of a desired material wherein each droplet has a positive or negative charge.
