A covered book comprises: a stack of aligned sheets, including a front and back cover, providing an edge surface; a first protective sheet located adjacent the outside of the front cover; a second protective sheet located adjacent the outside of the back cover; and a binding strip fixed to the edge surface, to an area on each of the covers, and to an area on each of the protective sheets. The first protective sheet is wrapped around the unbound edge of the book and is fixed with a pressure sensi...

In an air valve carburetor, additional fuel for cold start enrichment is provided by a primer pump operated by the throttle when the throttle is opened completely. The primer pump discharges through a jet traversed by the air valve, and the air valve is opened partially to expose the jet when the throttle is opened completely.

An electrode is disclosed having an electroconductive silicide surface on a suitable electroconductive substrate. The silicide surface is electroconductive and electrocatalytic. Also disclosed is an electrolytic cell containing an anode having a silicide surface on a suitable electroconductive substrate and an electrolytic process for the electrolysis of brines by the use of such an anode.

An atomiser having a tapered pump chamber in which a valved lipped piston is slidably mounted, the piston being compressed radially inwardly by the tapered pump chamber to ensure a tight seal between the valve and its valve seat.

In a ski of the type comprising a hollow core assembly provided with a ski top constituting unit, a ski bottom constituting unit which are firmly laminated to the top side and the bottom side of said hollow core assembly, and side members arranged at the lateral sides of this assembly, the hollow core assembly has, at a substantially central part of the ski relative to the transverse direction of this ski, a hollow structure defined (a) by a longitudinally extending central channel member having...

N--C.sub.1 to C.sub.4 -alkyl-5-bromo-ortho-cresotamides; their use as anticonvulsants. 5-Bromo-ortho-cresotamide may also be named 5-Bromo-2-hydroxy-3-methyl-benzamide.

A display panel includes a plurality of layers of gas-filled glow cells and a plurality of arrays of electrodes. One layer of cells is scanned once for each picture to be stored and displayed, and another layer is used to display the glow or picture with memory.

A projectile including, a housing, an optical tracker, and a gyroscope disposed within the housing, the housing having a nose section and a base section forming a chamber enclosing the tracker and the gyroscope, the nose section having a window, the optical tracker having an optical lens unit and an image detector unit mounted on the gyroscope, the optical unit being arranged to receive an image through the window and to transmit the image to the image detector unit, the gyroscope comprising, a ...

Magnetic device comprising at least one thin layer of a magnetisable material which has a preferred direction of magnetisation substantially at right angles to the surface of the layer and domain positioning structure. In the layer magnetic domains are maintained, moved, and annihilated by magnetic fields one of which is situated substantially in the plane of the layer and does not change direction and under the influence of which the domains are moved parallel to the axis of the magnetic field.

5-Bromo-ortho-cresotamide and N--C.sub.1 to C.sub.4 --alkyl-5-bromo-ortho-cresotamides are useful for the potentiation of aspirin. 5-Bromo-ortho-cresotamide may also be named 5-Bromo-2-hydroxy-3-methyl-benzamide.
