摘要:
On décrit un matériau de copie du type présentant sur l'une de ses faces (10a) une couche (B) comprenant une substance chromogène qui lors de sa libération sur un matériau de support (F) produit une marque visible. Avant l'application de ladite couche (B) sur le matériau de copie lors de la production, on applique une image visible (I) à ladite face (10a) de façon qu'elle soit visible à travers la couche appliquée ultérieurement, ce qui permet de distinguer aisément, entre autres, la face (10a) portant la couche (B) de la face opposée (10b) sur laquelle on doit éventuellement former une image supplémentarie (II) lorsque, par exemple, on utilise le matériau de copie pour obtenir des ensembles de copie multiples.
摘要:
Sheets of paper or other suitable material are formed into pairs (21,22) connected together along one edge (23) by folding or by means of adhesive, and such double sheets (20) are formed into stacks (10) for use in reprographic operations by a method in which a reprographic operation is performed simultaneously or successively on the two exposed faces of the pairs of sheets whilst they remain in face-to-face relation, and the two sheets of each pair are then separated into single sheets after completion of the reprographic operations. In this way, it is possible to utilise material of a weight or stiffness which could not otherwise be handled by conventional reprographic apparatus.

A laminate (10) is described having first and second external surfaces and comprising a first paper layer (11) of crepe paper laminated to a second paper layer (12) of extensible kraft paper.
摘要:
A cover 10 for a disc brake assembly comprises two spaced parallel side walls 12, 14, an outer wall 16, an open side 18 and respective aligned recesses 13, 15, which extend within each side wall from the open side 18. The arrangement is such that the cover 10 may be fitted to a disc brake assembly A with the calliper C thereof received within the recesses 13, 15 and the brake rotor R enclosed within the cover.
摘要:
Sheets of material, such as paper, having one one face a coating A of image-forming material (such as the CB coating of a carbonless copy system) are formed into pairs (51,52) connected together along one edge (53), by folding or by means of adhesive, with the coated faces (51 a , 52 a ) in face-to-face contact leaving the remaining faces (51 b , 52 b ) exposed, and such double sheets (50) are formed into stacks for use in non-impact printing processes by a method in which the printing is performed successively on the two exposed faces of the pairs of sheets and the two sheets are then separated.
摘要:
Packaging (10) for a stack of paper sheets (8) is described which includes relatively rigid top (16) and bottom sheets (14), a sleeve (12), and at least one band (18) to secure the package together around the stack of paper. Also described is a method of packaging a stack of paper comprising locating relatively rigid top and bottom sheets on the top and bottom of the stack of paper, and a sleeve around the stack of paper, and applying bands to secure the top and bottom sheets and sleeve in place to form a package. Finally there is described a method of loading paper into the drawer of a machine comprising the steps of: placing a package formed in accordance with the above mentioned method into the drawer; cutting the bands and removing them; and removing the top sheet and sleeve from the stack of paper.
摘要:
Means for inhibiting corrosion of a brake disc (15) of a disc brake assembly (10) associated with a road wheel (12) of a motor vehicle, comprising a member (11) adapted to be fitted in the road wheel and partially to define a volume containing the brake disc, said member including means for emitting a corrosion inhibiting vapour in said volume.
摘要:
An internal phase solution for a coating of rupturable material for application to a base sheet to form a pressure-sensitive record material comprises one or more colour-formers of which at least 90 % are monoamino and/or diamino fluoran derivatives dissolved in a solvent comprising 80 % to 100 % of one or more vegetable and/or animal oils. Preferably the colour-formers comprise only monoamino and/or diamino fluoran derivatives and the solvent comprises only one or more vegetable and/or animal oils. Dissolution of the colour-formers in the solvent may take place at a temperature in the range 100 °C to 135 °C and micro-capsules containing such a colour-former solution may be formed by conventional coacervation processes below 70 °C.
摘要:
An elongated article is wrapped by forming thereon a winding of a strip of a flexible wrapping material (12) which has a first face (13) carrying first and second portions (13 a ,13 b ) of a coating of an adhesive substance of a per se known kind which without the application of heat adheres strongly only to itself, the second face (15) being free from such adhesive substance, and by turning over a longitudinal edge portion of the strip which includes said first portion (13 a ) of the coating, as the strip is wound around the article, so as to bring it into face-to-face with the second portion (13 b ) of the coating on a previously formed turn of the winding.
