A high strength concrete particularly useful for precast, prestressed products comprising by weight of the wet concrete mix, 8 to 60 percent cement, .5 to 20 percent smooth-surfaced, vesicular, expanded perlite, 5 to 30 percent water, 0 to 12 percent pozzolan, and fine aggregate and coarse aggregate as appropriate and available in the circum- stances. The concrete provides superior bond to reinfor...

The present invention provides a weatherable protective surfacing film which can be laminated to various substrates, such as vinyl outdoor fabrics, by heat and pressure without requiring adhesives. The film has a unitary structure and is comprised of an acrylic polymer/fluoropolymer composition which has a composition gradient across its thickness such that one surface of the film is fluoropolymer...

This invention relates to a method and a device for transporting liquid in a dishwasher (19) from a liquid reservoir (22) to the dish which is placed in a tub in the machine. The liquid is conpulsory transferred to a liquid fog which condenses on said dish. Preferably the fog is generated by ultrasonic means (20).

A public suntan booth comprising in a small volume, a UV radiation generator and means adapted to its use, (e.g coin operated), in order that the user may obtain quickly and in any public place a face suntan sufficiently noticeable to attract attention.

In order to assure a safe activation and deactivation of resonant circuits on tags used for being placed on or in articles by means of small electromagnetic or electric fields easy to handle, regions are created in the conductive elements forming part of the resonant circuit, especially in the capacitor parts where the insulating material between two conductive elements in a precise manner is made...

A drum washing machine incorporates a drum, the drive shaft of which is connected to a position indicator that works in a contact-free manner. The rotor of the drive motor of the drum is coupled to a tacho-alternator torsion-resistantly. The tacho-alternator emits an incremental signal and is, together with the postiion indicator, connected to an evaluator. The evaluator registers the position of ...
