A self-processing camera for use with a film magazine (12, Figs. 2, 3 not shown), carrying a stack of film assemblies (32) each embodying a releasably contained processing liquid for producing transparencies by a diffusion transfer process, comprises a housing 14, Fig. 1, having flanges 24, 25 and a latch 30 for mounting the magazine, a pair of resiliently mounted pressure rolls 58, 60 positioned adjacent an exit 124 in the housing, and a rectangular frame-like transport element 106 for moving an exposed assembly between the rollers from the exposure position and ejecting it through the exit. The transport element is slidably mounted in a pair of channels (108) in the housing and comprises a member 114 extending outwards from a transverse frame member for engaging the film assembly in the exposure position. The magazine and film assemblies may be those described and claimed in Specifications 1, 156, 373 and 1, 156, 374. The surfaces 58a, 58b and 60a of the pressure rollers and the film assemblies may be shaped so as to vary the distance between the rollers as the assembly is transported there through, to prevent the processing liquid being squeezed out of the assembly. The transport element is manually operated by a handle 120 by moving it outwards, and then inwards to eject the forwardmost assembly; a safety mechanism comprising cams 134, 138, Fig. 13, engaged during the inward and outward movements by members 116, 118 respectively, and a spring-biased lever 142 are provided so that an assembly is not ejected until the frame has completed a maximum outward and inward movement thus preventing jamming. The ejected assembly may be received in a pivoted flanged plate as described and claimed in Specification 1, 156, 371, or super-imposed by an opaque sheet to allow processing to take place. Projections 33 may be provided on the camera for accurately locating the film assembly in the exposure position.

Filed: 1970-12-11
Abstract: 1327488 Safety belt with energy absorbing device TOYOTA CHUO KENKYUSHO KK 11 Dec 1970 [13 Dec 1969] 58984/70 Heading A3V [Also in Division F2] A vehicle safety belt utilises an energy-absorbing device A comprising a cylinder 3 within which a foamed plastics body 4 is held between one end 31 and a moveable pusher plate 5 and comprises a belt 21 which is connected to a rod 52 passing through apertures 32 and 41 in cylinder end 31 and foamed plastics body 4 respectively and fixed to the pusher plate 5. The other end 6 of the cylinder may be fixed to a portion of the vehicle as shown or may be attached to the end of another belt. Forward motion of the wearer of the safety belt causes a tension in belt 21 thereby pulling the plate 5 towards the end 31 of the cylinder and compressing the foamed plastics body 4, the cellular destruction of which absorbs part of the kinetic energy of the wearer of the belt. In one modification the pusher plate 5 has a conically shaped pushing surface and is embedded in the plastics foam, while in a second modification the end wall 31 of the cylinder is separate and larger in diameter than the cylinder and can be fixed to the body of the vehicle by bolts which also secure the end 31 to a circular flange which forms the open end of the cylinder. A second embodiment B in Figure 16 has a plastics foamed body held between plates 91 and 94 of a link of hexagonal cross section each of the six plates 91 to 96 being hinged to its two nearest neighbours. Belts 22 and 23 are secured by means of 101 and 102 to opposite hinged portions so that tensions in the belts cause the plates 91 and 94 to relatively approach each other thereby compressing the foamed body as before. This embodiment is suitable for placing under a seat of the vehicle, the belts being guided by pulleys. The plastics foam is suitably foamed polyurethane or polystyrene.

Title: Improvements in or relating to television systems
Inventor: ILLETSCHKO GERHARD
IPC: H04N9/78
Filed: 1969-12-11
Abstract: 1,244,285. Television. FERNSEH G.m.b.H. 11 Dec., 1969 [11 Dec., 1968], No. 60593/69. Heading H4F. A PAL video signal A with “ line offset may be separated into substantially pure, whole bandwidth, luminance Y and chrominance Cr signals, despite their overlap in the highfrequency portion of the signal A, by forming the sum (C) and difference (D) of the undelayed signal A and the signal A delayed for one line period (B), delaying the signal D for a further line period (signal E) and linearly combining the signal E with signals C and D. Reliance is placed on the luminance and chrominance contents of each set of three lines being closely similar, and on the fact that the phase of the colour sub-carrier is displaced by 180 degrees every two lines while the phase of the PAL switched component V of the chrominance signal is identical every two lines. The circuit of Fig. 1 thus effectively forms the sum and difference of pairs of lines which are separated by one other line, e.g. the 1st and 3rd lines of a field. In a modification, Fig. 2 (not shown), the Y signal is derived as in Fig. 1, and the Cr signal is formed by adding signals C and D and subtracting 2Y therefrom. In another embodiment, Fig. 4 (not shown), the components U and V of the chrominance signal are derived by subjecting the subcarrier of signal E to a 90 degrees rotation of phase, and forming the same and difference thereof with signal D. In a further embodiment, Fig. 5 (not shown), the signals D and E are synchronously demodulated to give signals proportional to (V - U) and (V + U) which are then matrixed with the Y signal to give colour or colour difference signals. It is also possible to filter out that part of signal A which contains only low-frequency luminance information and to add it to the luminance signal derived from processing the rest of the signal as described above, either directly, or after a one-line delay period, Fig. 6 (not shown). The PAL signal may still be modulated on an I.F. subcarrier, this being advantageous because the delay devices exhibit relatively greater bandwidths at higher frequencies.

Abstract: 1,245,530. Photographic film units. POLAROID CORP. Dec.16, 1969 [Dec. 16, 1968], No.61243/69. Heading G2A. In a container 12 housing a stack of film units 42, as disclosed in Specification 1,245,529, the units are urged towards the exposure aperture 26 by means of a resilient support member 52 which engages the film unit only along marginal portions thereof. Member 52, which may be of spring steel, is a rectangular frame 54, 56, 58, 60, and this is engaged against the film units by a central H-shaped part which has legs 64, 66 in the form of cantilever springs which bear against the inner surface of the rear wall 16 of the container 12. Thus the frame portion engages the film unit only along its margins, so that it is evenly supported, which improves the uniformity of the processing over the area of the film. The frame portions 54, 58 may be eliminated, so that only portions 56 and 60 support the film.
Patent GB-632062-A (GB)
Abstract: 632,062. Dressing fish. FISADCO, Ltd., and SCHLICHTING, K. F. Jan 22, 1948, Nos. 2029 and 18183. [Class 28(ii)] In removing gills from herrings &c. by a bladed rotor as in Specification 488,159 after they have been split through the back and opened out for gutting as in Specification 313,335, [Class 28(ii)], the two halves 20 of the split gills are held correctly spaced apart for engagement by the known spaced gill removing points 14 of each rotated blade 4, by one or more guides. Fig. 3 shows a fold 23 in the fish belly which results in the gill halves 20 being too near to each other. This fold 23 is prevented by a curved inner guide 22 fixed on the support 10 of the complete gill remover. If the fish is larger than usual the gill halves 20, Fig. 5, would be spaced too far apart, but outer guides 24, 26 on the support 10 hold the belly flaps in so that the gills 20 make close contact with and are scraped out by the points 14 and the adjacent inclined edges 16 of the rotating blades. These outer guides are flared at 27 to receive and guide the belly flaps.
