Title: Packaged food products
IPC: B65B25/06
Filed: 1965-11-10
Abstract: 1,128,929. Food packages. REDDI-BACON, Inc. 10 Nov., 1965 [17 Nov., 1964], No. 47683/65. Heading B8C. A package for pre-cooked food products, which are to be reheated in a toaster prior to use, is made from metal foil sheets coated on the inside with material which is unaffected by the contents of the package and coated on the outside with a material which is heat resistant and electrically non-conductive to prevent short circuiting of the toaster elements. In one embodiment pre-cooked bacon rashers 10, Fig. 1, are enveloped within a strip of laminated aluminium or stainless steel foil, the sheet being folded about a fold line 15. Uncoated edges 12a of the superposed sheet are double folded, Fig. 3 (not shown), so that they are completely encased by the exterior coating 18 of the foil. The partially closed package is then subjected to pressure to expel air from the package, and the remaining end with edges 12b is heat-sealed in conventional manner. At this end, uncoated edges 12b are still exposed, but, as it is intended to protrude from the toaster, the exposed foil will not cause short circuiting. In a modification a notch 24 may be cut out at either end of the fold line 15, in order that no part of the uncoated edges 12a is co-linear with the fold line 15. Alternatively a triangular section, corresponding to the cut out notch 24, may be folded in along the fold line before the sides are double folded. In the second embodiment, the package is formed from two laminated webs (32), (34), Fig. 6 (not shown), one end and two sides being double folded as previously described, and the final open end (46), Fig. 7 (not shown), being heat-sealed or crimped. In a further modification a single laminated aluminium foil sheet (50), Fig. 9 (not shown), has its sides (52) turned inwardly prior to being folded about line (54). The sides (58) and ends (62) are then crimped or heat-sealed together. The outer coating used may be an epoxy resin or a polyester or alkyd material. This coating is generally darkened by the addition of carbon black or manganese dioxide. Alternatively clays, e.g. kaolin, may be added to the plastics coating. The inner plastics coating may be a polyethylene or polypropylene resin. The whole package may be completely insulated by dipping it in a suitable plastics resin after sealing.

Title: Improvements in or relating to apparatus for combining signals reproduced from a rotary multiple head unit tape recorder
IPC: G11B15/14
Filed: 1967-11-03
Abstract: 1,147,279. Reproducing signals from multiplehead tape apparatus. NIPPON ELECTRIC CO. Ltd. 3 Nov., 1967 [4 Nov., 1966], No. 50039/67. Heading G5R. Apparatus for combining reproduced signals from a rotary multiple head unit tape recorder comprises: first means for subjecting one incoming signal, reproduced from one head, to pedestal clip and envelope detection, and second means for using the pulse output from the first means to determine the switching phase for combining all the reproduced signals sent from the multiple head (including the one abovementioned), into a continuous signal. As described, such apparatus for combining signals from successive heads on the rotary head block of a magnetic tape information recording /reproducing apparatus comprises a horizontal synchronizing pulse generator controlled by the continuous output signal and a combining (otherwise switching) circuit (the " second means") controlled partly by the switching phase pulse output the ("first means"), partly by the reference pulse train from the head block, and partly by the horizontal synchronising pulse. As shown, for television reproduction from video tape, the tape 4 passes from a supply reel 3 to a take-up reel 5. The signals previously recorded on the tape are reproduced by four circumferentially-staggered read heads on a rotary head block 1 and respectively amplified in pre-amplifiers 6 to 9. The resulting signals 101 to 104 are passed to a switching device 10 where they are composed into a continuous signal 107 which is demodulated at 12 into a television signal 109. The switching device 10 is controlled partly by a reference pulse train 105 whose frequency depends on the rotary speed of the head block, partly by a horizontal-synchronising signal from a pulse generator 13 associated with the demodulated television signal 109, and partly by a signal 106 from a unit 11 into which signal 104 is fed. The signal 104 is arbitararily chosen from the four signals 101 to 104. The unit 11 is a phase pulse generator which generates a pulse dependent on the envelope of signal 104. This unit comprises, in series connection: an amplitude limiter amplifier, a pedestal clipper, a further amplitude limiter amplifier, an envelope detection circuit, and a waveform shaping circuit.

A method of lasting includes the steps of placing an upper loosely over a last 5 having marks where the longitudinal axis XY-L and transverse axis XY-W cross the edge of the last sole, bringing four corresponding marks on the upper into registry with those on the last, clamping or gripping the upper at least at the four marks, successively stretching the upper longitudinally and laterally about the last, laying the last margin over the edge of an insole on the last bottom and attaching the lasting margin to the insole. The axes XY-L and XY-W are chosen so that the lasts in a range of sizes each present a similar outline to the side lasting devices (see Fig. 3). Apparatus for performing the method includes conventional toe and heel lasting assemblies 28, 29 and side lasting assemblies each consisting of a series of lasting fingers 1. The fingers 1 are mounted on a support plate 2 having an upper surface corresponding to the profile of the last (Fig. 2). The fingers 1 and plate 2 are carried in a housing 3 which is reciprocated by jack 6. Each finger 1 carries a spring loaded hook 21 which grips the lasting margin so that as the housing 3 is moved inwardly by jack 6 the upper is tensioned and laid across the insole by the ends 7 of the fingers 1 where it is attached by adhesive. The fingers 1 are arranged so that they follow the outline of the last bottom (Fig. 3) by a pair of cam surfaces. The rear edge of slide 9, which is moved into operative position by jack 11, engages extensions 1<SP>1</SP> of the fingers 1 to arrange the fingers for the outside edge of the last bottom and the rear surface 12 of plate 2 arranges the fingers for the inside edge of the last bottom. The fingers 1 are held in their adjusted positions by an elastic pad 15 which is clamped against the fingers 1 by a jack 18. In a modification (not shown) the fingers 1 can be adjusted to allow for the difference in profile between the inner and outside edges of the last.
