Title: Applying patterns to webs
Inventor: KARLSSON LARS
IPC: D06B11/00
Filed: 1983-05-04
Abstract: A method of manufacturing a web having a multicoloured pattern, wherein an array of applicators for each colour apply strips of colour of varying length but of modular width. Each applicator covers a modular width of the web, and the applicators together cover the width of substantially the entire web. The applicators are activated individually there being thus obtained a pattern which can be varied at will. The invention also relates to colour- applying apparatus including several applicators having modular widths, e.g. in the form of a colour roll on which colour is spread out with a scraper, together with a series of individually operable roll portions, with which portions of the web can be pressed against the colour roll or lowered out of engagement with said roll; or a screen roller similarly arranged; or an array of slot-like nozzles individually operable.

Title: Tool for use in tightening and releasing sunken nuts
Inventor: WILLIAMS JOHN
IPC: B25B13/48
Filed: 1983-09-21
Abstract: Sunken nut 16 is tightened onto shaft 30 by inserting plate-like portion 12 of tool 10 between one flat side of the nut 16 and the confronting surface of surrounding hub 28 (e.g. on a commercial vehicle wheel) and turning the tool 10 by means of a socket spanner 24, 26 applied to hexagonal boss 22, the portion 12 turning the nut 16 by pressure on corner 14 as a result of reaction of the tool 10 with the surrounding hub structure. Release of the nut 16 is achieved by corresponding turning of the tool 10 in the opposite direction. The surface of the plate-like portion 12 facing the hub wall may be convex and reversal of the tool then permits expansion of the range of sizes with which the tool can be employed. Other arrangements may be provided for permitting the tool to be turned. <IMAGE>

Title: Bearing means for a gun barrel
Inventor: HALLQVIST STEN
IPC: F41A25/22
Filed: 1985-04-10
Abstract: The invention relates to bearing means for a gun barrel 1 in the breech casing of a large-calibre firearm of the type in which the breech casing comprises a substantially sleeve-formed member 2 enclosing the rear part of the gun barrel. The bearing means comprises two separate ring-shaped parts 4, 5 located at the side of each other and radially displaced so that one part 4 is engaging the gun barrel surface and the other part 5 engaging the sleeve member 2 of the breech casing. The two parts 4, 5 are separated by means of a number of cylindrical pins 8 so that a small air gap 9 is formed between them which prevents heat from being transferred from the gun barrel 1 via the bearing means to the breech casing when the gun barrel is heated upon firing.

Title: Extraction mechanism for injection moulding machines
Inventor: PENNELL JACK FRANK
IPC: B29C45/42
Filed: 1986-05-12
Abstract: A programmable mechanism for extracting a moulded article from an injection moulding machine comprises a support member (14) movable in a direction perpendicular to the plane of separation of two replaceable mould members (6,8), and a support arm (30) on the support member (14) capable of arcuate movement about the support member (14).

There may be a controlled pivoted joint in the arm, Figure 9 (not shown), to provide further control over the extracted position of an article and the extraction path. Use of the mechanism facilitates changing from moulding of one article to moulding of a different article, and results in a faster extraction operation. The mechanism is controlled by a control device into which control signals are fed, such that the movements of the mechanism are related to the particular pair of mould members (6,8) in use. <IMAGE>
