The invention is directed to an unfoamed foil of at least one thermoplastic resin, said foil being capable of serving as an adhesive when softened and having included therein at least one blowing agent, and to the use thereof in preparing laminates.

Particles (I) which are suitable as carriers for electrophotography consist of a) a magnetic core and b) a shell of alumina, chromium oxide, molybdenum oxide, tungsten oxide, silica, tin oxide or zirconium oxide or a mixture thereof and particles (II) consist of a) a magnetic core and b) a shell of titanium oxide and are obtainable by decomposing a titanium tetraalcoholate in the gas phase by reaction with steam and/or oxygen in the presence of agitated cores, and these particles are used in ele...

The amplifier (201) uses transistors (401,403) such as MOSFET transistors in a current mirror configuration. The transistors (401,403) are easy to package as surface mount devices. The drain port of the first transistor is coupled to an output signal (207) and a bias input signal (VB+). A gate port of the first transistor is coupled to a bias control input (117) and the signal input (115). The source of the first transistor and the source of the second transistor are coupled to an electrical gro...

A wiping cloth or the like, suitable for wiping glossy hard surfaces, comprises a sheet substrate carrying a liquid, for example, a streak-free cleaning composition. At least one external (wiping) surface of the substrate has flattened areas including thermoplastic material coalesced by the application of heat and pressure and open areas, and this external surface is immediately adjacent to a core of bulky high-porosity fibrous sheet material.

In an article suitable for wiping surfaces which comprises an elongate web substrate impregnated with a liquid composition, migration of the liquid along the length of the substrate is substantially prevented by dividing the substrate into a plurality of individual areas by means of a repeating pattern of liquid-repellent barrier material, for example, wax or certain resins, extending across the whole width of the substrate. This measure prevents fluid loss by capillary action and evaporation wh...

A wiping cloth or similar article especially suitable for wiping glossy hard surfaces to give a streak-free result comprises a flexible absorbent substrate of fibrous material, having a base weight of at least 50 g/m.sup.2 and a thickness of at least 0.5 mm, advantageously consisting at least partially of natural cellulosic fibres, treated with a cationic polyacrylamide to enhance its soil capture capability, and carrying a fully formulated liquid cleaning composition.

The invention provides catalysts suitable for hydrotreatment of mineral oil which contain an oxide and/or sulphide derived from a metal of Group VI (B) and one from Group VIII metal and a transition alumina and which show an oxygen chemisorption above 185 micromoles per gram, preferably between 200 and 300. Preferably tha catalysts are free from anions of strong mineral acids. These catalysts can be prepared by impregnation of a transition alumina with an ammoniacal metal solution having an init...

An improvement to a process for fabricating packages suitable for use in integrated circuits having a ceramic portion and an electrically conductive portion containing a high density of a plurality of individual component leads and at least one connecting lead wherein the connecting lead extends from a central pad portion through the ceramic portion to a frame portion. The component leads are spaced apart from the central pad portion by a predetermined pattern and extend through the ceramic port...

The invention is an apparatus suitable for playing a card game such as Poker, Black Jack, or the like without the use of playing cards. A box-like housing is provided which contains two belts. On one belt the values of playing cards are indicated in a regular rectangular grid. The second belt fits over the first belt and has a number of apertures or windows through which some of the card values on the first belt can be viewed. The belts differ from each other in length by an integral multiple of...

The rotor of a disc brake apparatus for bicycles comprises a spider that flatwise overlies the outer face of one spoke flange on a wheel hub and is secured by spokes that have their hook portions extending through it and that spoke flange. A flat annular disc has radially inwardly projecting tabs that are secured to the spider and hold the disc in axially spaced relation to the spokes. A U-shaped caliper body straddles an edge portion of the disc. On a shorter leg the body has a fixed brake pad;...
