A pellicle for use in projection printing comprises a pellicle in which the transparent film is formed from a polyvinyl butyral resin or from a casting composition which is a mixture of polyvinyl butyral resin and a dispersion of colloidal silica and a silicone resin which is a lower aliphatic alcohol-water solution of the partial condensate of a silanol. A pellicle employing such films are useful...

The object of the invention is to improve the intensity of the mixing process. To this end, a gas space is formed in the mixing rotor of the appliance between an upper row of vanes and a lower row of vanes, which gas space is hermetically sealed in the axial direction against the rows of vanes and connects the axial intake orifice for the gas and a radial gas discharge orifice.

The disclosure relates to what may aptly be termed "genderless", or "hermaphroditic", or perhaps "unisex" electrical connectors, and more particularly to such an electrical connector having a keying system which minimizes the chance of two incompatible cables being connected together.

The invention involves in short a ground conducting device included in a lightning protector for boats. The ground conductor device is composed of basically a metal cloth (12) of at least a half square meter in size, which gives a contact area of at least 1m<2>. At the one side of the cloth (12) is an electric conductor (10) from that part of the lightning protector, which is above deck, fastened ...

The spirit level has its one end part resting in a first seat, whilst its other end rests in a second seat. At least one of the seats is attached to a rotatable rotation-symmetrical body to which it is eccentrically related. Thus, a rotary movement of the body imparts an adjustment to the end part of the spirit level. - Also, at least one seat is of elastic material so that the long tube is clampe...

The invention concerns a gripping apparatus (1) of a vacuum type for lifting full bags (3).It has been shown, that with this type of apparatus, it is difficult to bring about a sufficiently reliable grip on the bags (3) because of unsatisfactory sealing between the vacuum grip device and the bag while being lifted.Significantly improved operation has been achieved in a simple manner by the inventi...

Method of killing the moth of the family Dioryctria esp. for the spruce cone moth, Dioryctria abietella, is effected using (Z,E)-9, 11-tetra decadienyl acetate. It is a pheromone acting as a sexual attractant. (Provisional Basic previously advised in week 8443)

The use of (Z)-9-tetra decenyl acetate (I) for killing the spruce cone moth Dioryctria abietella is described. (I) is a sexual pheromone for Dioryctria abietella. Z-9-tetra decenyl acetate inhibits this attraction effect by preventing the identification of the females. (Provisional Basic previously advised in week 8443)
