A security system having a two way wireless keypad which operates in a particular manner for improved operation. The keypad processes information to effectively reduce communications between the control panel and the keypad. The keypad selectively activates and deactivates a transmitter and receiver arrangement for power conservation reasons. The system provides confirmation of communications betw...

Polyurethane foams having improved flame retardant properties employing small quantities of halogenated polyaromatic resin flameretardant additive have been discovered. Brominated polystyrene resin is particularly preferred. The additives may be physically suspended in the polyol prior to reaction with a polyisocyanate in the presence of a polyurethane catalyst in a conventional manner to produce ...

A low concentration (0.1 to 0.5 mM) of aluminum ions is added to an organic wastewater to selectively raise specific bacteria which can grow without producing unpleasant odors. The bacteria is used for treating the organic wastewater of high density without producing odors thus contributing to the minimum size of a wastewater treatment system. Then, increase of the aluminum ions to a high concentr...

La présente invention concerne un procédé de préparation de polynucléotides sur support solide dans un réacteur en forme de colonne à travers laquelle on fait circuler les solutions de réactifs et/ou solvants, caractérisé en ce que la phase solide constituant ledit support solide est immobilisée dans ledit réacteur, et lesdites solutions migrent dans la colonne et à travers la phase solide selon u...

Absorbent products and components for use in absorbent products are disclosed. These absorbent products comprise pressure-sensitive adhesive microfibers and thermoplastic polymer microfibers, that when incorporated into absorbent products provide good liquid transport properties, resiliency, and attachment systems; and further mask odors associated with bodily fluids.

An external color frame is synchronized with a local color frame without producing a pixel position error. A frame synchronizer synchronizes a frame from an external television signal with that of a local television signal. A wide screen oriented high definition television signal is used as the external television signal, the image quality of which is improved by adding a support signal to the mai...

Fibre-free, thermally insulated composite board consisting of a shaped board containing essentially highly porous inorganic material and having a side surface having at least one recess in which there is embedded a fibre-free insulation layer which contains essentially microporous inorganic material.

A method and system for maintaining a routing path between a selected workstation (18) and a mobile workstation (36) within a multisegment local area network (10) wherein individual segments (12,14,16) are interconnected by a router device (28,30) and wherein selected segments (14,16) include radio frequency transceivers adapted to provide a wireless communications link with mobile workstations (3...

Method and device for feeding the cavities of a stamp for the moulding of tiles with at least two layers of different material by means of a first feeding frame, driven by alternating motion, placed at one side of the cavities, and able to move between two end travel positions in which it is situated respectively above said cavities and at a position away from them, and a second feeding frame plac...

In the present state of the art the determination of cross-linking, pyridinoline and keratan sulphate in biological fluids is not performed by methods which are available on the market to all laboratory workers. The identification of these analytes mainly takes place during research and investigation by means of very difficult procedures which are not completely error-free and are therefore not re...

This invention regards an aerated sun and rain roof with automated closure, fixed, or with rotating elements for its complete automatic closure in relation to the rainfall rate itself; or, in conditions of solar heating, for the consequent vertical thermal selection of its layers as the atmosphere below it changes, in relation to variations in volume and specific weight.
