Patent GB-1316504-A (GB)
Title: Photographic apparatus
IPC: G03C5/04
Filed: 1970-11-23
Abstract: 1316504 Cameras for self-developing film POLAROID CORP 23 Nov 1970 [21 Nov 1969 (2) 28 Nov 1969 2 Jan 1970] 55628/70 Heading G2A The apparatus is substantially the same as is described and illustrated in Specifications 1316502 and 1316503, the claims being directed to the means for moving the exposed film unit through and beyond the processing rollers, which means is movable in a plane angularly disposed to the film exposure plane, and driven by means which moves in a plane parallel to the exposure plane. As in the above-mentioned Specifications, the uppermost film unit in container 30 is situated in the exposure plane 32, which is angled with respect to the bottom wall 34 of the main camera body. After exposure, the film unit is moved between the processing rollers 62, 64, and a drawer 38 moves with it into an extended position so as to maintain the film unit in a light-tight enclosure, as previously described. Within drawer 38 is a spring member 94 having an elongated resilient part 106. The end of member 94 is shaped as a loop 108 with a back-turned flange 110 having a downwardly biased end 112. The member 94 is normally biased upwardly towards the position shown in Fig.4. As the drawer and film unit move out to the extended position, as shown, the end of the film unit is guided into the loop, and wedges therein. The unit 36 is a relatively rigid structure, and as it is drawn completely clear of the rollers the bias imparted by the end 112 of the loop 108 causes it to be pivoted downwards as shown at the left hand end of Fig.4, which shows the drawer 38 at its farthest extension. The drive is now reversed, and the drawer moves back into the main camera body. Member 106 is driven downwardly by spring elements 120 which engage it at its edges, so that the film unit passes between, and is guided beneath container 30. In this way the film unit is subjected to the minimum amount of bending or distortion, which would impair the quality of the picture.

Patent GB-2035745-A (GB)
Title: Comb-filtering colour television signals
IPC: H04N9/64
Filed: 1978-11-24
Abstract: Comb-filtering is used to remove alias components in a sub-Nyquist sampled digital PAL or NTSC colour television signal, the comb-filter comprising delay elements giving a delay D2 equal to one picture period accurate to a small fraction of a colour sub-carrier cycle. Stationary picture impairments introduced in systems employing a one-line or one-field delay are thereby avoided. The moving-picture impairments thus introduced can be reduced by an adaptive system which switches between or, better, combines with a weighted adder the effects of a one-line and one-picture delay under the control of a motion detector. The comb-filtering is normally applied to a high frequency band only. Where tandem filter arrangements are used, the picture delay is operative to effect comb-filtering on the h.f. band in both filter arrangements, but to provide a pure delay upon lower frequencies in one filter arrangement only. <IMAGE>

Title: Improvements in and relating to the dyeing of cellulose fibres
IPC: D06P1/22
Filed: 1979-05-08
Abstract: Cellulosic fibres, and especially fabrics comprising cellulosic fibres, are treated in a bath containing, in addition to one or more micro-dispersed vat dyes, a swelling agent for the cellulosic fibre, followed by the necessary reduction and re-oxidation treatment. It is found that the presence of the swelling agent, suitably one of a range of defined water-soluble polyoxyethylene glycols, improves the penetration of the dye and the uniformity of dyeing. This is especially the case where the cold process is used, that is, where the treatment in the reduction bath and any subsequent storage (e.g. of the wrapped roll of fabric after passing in the alkaline reduction bath) are effected without external application of heat. An alkaline reduction padding bath containing defined amounts of dextrin, sodium silicate and ammonia is recommended to enhance further the uniformity of the dyeing; in particular the incorporation of ammonia is found to promote the evolution of heat in the storage phase of the cold process.
