Title: Retortable packages
Inventor: BENGE TERENCE ALEXANDER
IPC: B65D77/20
Filed: 1986-05-29
Abstract: A retortable, hydraulically solid, sealed package (10) containing a liquid or semi-liquid food product (24) comprises a thermoplastics container (12) formed by a thermo-forming process and a heat-shrinkable thermoplastics closure diaphragm (20). The closure diaphragm is heat-sealed to a rim (18) of the container after the headspace above the product has been evacuated, and is subsequently subjected to external pressure so as to be non-elastically stretched and made to lie wholly in contact with the enclosed product. When retorted (e.g. for sterilisation) the package suffers no visible deformation of the container (12), despite the considerable volume shrinkage of the container which may occur. The loss of volume caused by this volume shrinkage is accommodated by a reduction in the concavity of the diaphragm (20) caused by a corresponding heat-induced shrinkage of the diaphragm material. The diaphragm continues to exhibit a pleasing, smooth or smoothly curving surface, and the retorted package has a consumer-acceptable appearance.

Title: Control method and system for a printer
Inventor: ONIZUKA YASUKI
IPC: B41J19/18
Filed: 1987-01-22
Abstract: In a serial printer in which the position of a print head (6) moving across a recording medium is indicated by the count in an address counter (17), an initialise command (e.g. at power on) moves the head to a stop position in a home region, entry into which region is detected by a home sensor (11). At the stop position, the address counter (17) is set to a predetermined initial value N, such as 1. Each time a subsequent initialise command is received the print head is returned to the stop position in the home region and a comparison made (18) between address counter (17) and the initial value N. The address counter is reset to the initial value N only when the difference between the comparands exceeds a predetermined amount, such as 1. There is therefore no fear of the print start position and the print region after an initialising operation being displaced from those before the initialising operation, so long as printing is continued without turning off the power after it has been turned on. <IMAGE>

Title: Forming convolutions in metal cylinder
Inventor: WILLIAMS BRIAN ORMONDE
IPC: B21D15/06
Filed: 1987-12-19
Abstract: A metal bellows is formed from a metal cylinder (15) by urging an inner rotating forming tool (17) outwardly to stretch and bend the material of the cylinder. As the material distorts, the bending action results in a reduction in length of the cylinder. Outer rotatable forming tools (20, 21) engage the cylinder (15) on either side of the inner forming tool (17) and are mounted on actuators (24, 25) so that during the process the outer forming tools are moved toward one another as indicated by arrows (B). This movement is synchronized with the distortion of the cylinder (15) so as to allow for its reduction in length. The outer forming tools (20, 21) may commence movement towards one another when the inner forming tool (17) has completed 75% or more of its total outward movement. Adjustable mountings (24', 25') enable the outer forming tools (20, 21) to be moved towards or away from drums (11, 12) supporting the cylinder (15). <IMAGE>

Title: A warp knit fabric structure
Inventor: PORTER ALLAN WILLIAM HENRY
IPC: D04B21/06
Filed: 1989-09-05
Abstract: In a single bar warp knit fabric structure in which one thread is supplied to each needle, multiple needle overlaps are made by each thread at every course, whereby only the last pant of the overlap forms a knit loop in the last wale to be crossed (e.g. wale a in course X). The preceeding part of the overlap is divided into two components, a weftwise traverse and a warpwise part, and is held by at least a double thread crossing in each of the adjacent wales by means of the neighbouring threads. Each wale and course has a single loop only for each needle which, with the warp and weftwise division of the overlap parts not forming knit loops, gives a dimensional uniformity and stability with bulk not previously achieved. In another embodiment the threads may form stitches in adjacent wales so that only a single needle is overlapped in each case without forming a stitch. <IMAGE>
