Title: Electronic cameras
IPC: H04N5/91
Filed: 1979-02-19
Abstract: In a camera which provides a print of a viewed scene, electric signals representing the scene pass to a display device and a signal storage device, e.g. a magnetic tape recorder. When the operator is satisfied with the display, the stored signals are applied to a printer, to which there is fed from a cassette within the camera a sheet of image- receiving material, this sheet being subsequently ejected from the camera. The scene is imaged by a lens (14) through a colour separator (15) on to a charge coupled device (16) from which image- representing signals are applied via an analogue-digital converter (18), a memory (20), and a digital-analogue converter (22) to an electro-optical display device (24) and also to the magnetic tape recorder (26). The display device may be a panel constituting one wall of the camera (10). To make a print of the displayed image, signals are read from the recorder (26) and applied to a printer (28). The printer is preferably of the kind which converts the signals into pressure pulses which cause the transfer of colouring materials from a transfer sheet to the image-receiving sheet. <IMAGE>

Patent GB-2040877-A (GB)
Title: Tissue dispenser
IPC: A47K10/32
Filed: 1980-01-02
Abstract: A container 1 for a succession of moist tear-off non-woven-fabric wipes possesses a lid 2 having not a slit outlet but a non-linear outlet 11 of fixed shape and optimised dimension, e.g. circular, rectangular, semi-circular, etc., so that the uniformity of operation reduces the need to remove the lid for re-engaging the sequence of wipes in the orifice. The unexpected net effect is of less moisture loss, even though the orifice is larger. This objective is also attained by an improved seal between an inwardly turned flange 12 on the container mouth and a tapered flexible wall 2a on the underside of the lid, the two parts being held in engagement by a thickened end 5 to the lid skirt engaging in a circumferential vessel groove 3. <IMAGE>
Patent GB-2074124-A (GB)
Title: Paper tube containers
IPC: B23B31/40
Filed: 1980-01-15
Abstract: A paper tube container (Fig. 1 not shown) has a window or aperture in its side wall which is of double convolute wound construction formed by winding an apertured blank. A paperboard bottom is secured in position by having a peripheral flange around which is folded a bottom end flange of the side wall. The window or aperture in the side wall provides a zone of axial weakness that is a source of potential buckling under the axial stresses imparted on the side wall during the folding of its bottom end flange by a folding tool 31 and such buckling is resisted by inserting a expansible mandrel 30 into the tubular blank before the folding and increasing the effective diameter of the mandrel to hold the tubular blank from within. <IMAGE>
