A respiration monitor and x-ray trigger apparatus, wherein analog respiration signals (198) are amplified and divided (200) into respiratory and heartbeat components. The analog respiratory components are processed (300), digitized and further processed to yield indications of respiratory extrema (400) and respiration rate (600). The analog heartbeat components are processed (800) to give indicati...

A modified low-density flexible polyurethane foam product having a relatively high degree of firmness as well as commercially acceptable dielectric heat sealing characteristics. The product formulation includes an intermediate constituted by a mixture of polyol and a polymer/polyol in a ratio imparting to the product a predetermined degree of firmness, and a thermoplastic additive whose dielectric...

Porous, cross-linked polymeric materials comprising hydrocarbon residues can be sulphonated to produce sulphonated polymers which are able to absorb large volumes of ionic solutions and also act as ion-exchange resins.

A composite brake caliper includes a support member (1) of cast iron which has a support portion (11) bounding a through recess or opening. At least the support portion is at least partially covered by a body (3) of a precision-mouldable material, such as aluminium. The mouldable body may have a portion extending into the through opening of the support portion and having a precision-cast internal ...

A method of facilitating the incorporation of hydroxypropyl methyl cellulose (HPMC) into a liquid formulation containing water which comprises: 1. forming a liquid premix of hydroxypropyl methyl cellulose dispersed in an aqueous-free organic liquid medium in which it does not swell or dissolve, selected from the group consisting of liquified nonionic surfactants, fatty acids, anionic surfactants a...

Atomized metal is made from a source of molten metal which is fed into a vessel in finely divided particles, said vessel having a sidewall terminating in an endwall through which atomizing gas and molten metal are introduced from an external source to said vessel through a nozzle sealed to said endwall, a gas ingress port therein being spaced from side endwall. The sidewall, endwall and nozzle coo...

A highly water absorbent polymer having high resistance to salt solution is prepared by crosslinking a hyrophilic polymer or copolymer having carboxyl and/or carboxylate groups and water content of 10 to 40 wt. % with a crosslinking agent having at least two functional groups capable of reaction with said carboxyl and carboxylate group. An improved hydrophilic polymer is produced by polymerizing a...
