Abstract: 343,587. Boxes; packing. STONE, A. A. and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Nov. 23, 1929, No. 35941. [Classes 18 and 94 (i).] The slides of slide and shell packets, having a bottom cover flap 4, Fig. 4, with side wings 9 adapted to be folded down to stiffen the sides of the packet, are fed, with their superposed charges of cigarettes, by a conveyer D to folding apparatus shown in plan in Fig. 1. The flaps 1, 2 are turned over by folders (not shown), and the flaps 3, 4 are turned vertically upwards by folders 5, so that the packet arrives opposite folders 6, 7, 8 in the condition shown in Fig. 5. The conveyer halts, and folders 6, 7 are swung about vertical pivots through right-angles into the position shown to bend the flaps 9 at right-angles to the flap 4 as shown in Fig. 6. This movement is effected by a rod 16 moving in a guide to press against the back of the folder 6, links 12, 14, 13 transmitting the movement to the folder 7. A spring 15 returns the parts to inoperative position when the rod 16 is retracted. The rod 16 carries an extension 20 engaging the top of the folder 8 with a pin and slot connection 21, 22. This allows the folders 6, 7 to complete their working strokes before the folder 8 is turned down, about a horizontal pivot, to fold the flap 4 down on to the cigarettes, in which position it is held by a guide during the subsequent travel of the conveyer D.

Abstract: 1283342 Frozen food packages J E HUGHES 4 Nov 1969 [5 Nov 1968 31 Dec 1968 17 July 1969] 52352/68 61804/68 and 36008/69 Heading B8C [Also in Division G1] A temperature indicator comprises an elongate body, e.g. a pocket 13 formed in the lid 12 of a frozen food container 10 the body containing an indicating dye material 15 at one end, and a frozen transmitting medium 17, e.g. a frozen stick of brine water-alcohol mixture enclosed within a transparent or translucent plastics capsule 16, so that when heated above its melting point, the medium 17 disperses the dye to indicate irreversibly that defrosting has taken place. The capsule 16 may be held in place in the pocket 13 by an adhesive foil or it may be a force fit in the pocket. In an alternative embodiment, the capsule may be cylindrical with a closed pointed end containing the dye for insertion into frozen food, and an indicator disc of porous plastics material may be used to close the other end of the indicator thus enclosing the frozen transmitting medium, so that when the transmitting medium melts, the dye passes through it and becomes visible on the indicator disc. A second indicator material, e.g. a dye of a colour different from the first may be disposed at the same end of the indicator as the indicator disc, so that it becomes visible if the temperature in the locality of the indicator disc, i.e. at the outside of the frozen food into which the indicator is inserted, rises above the desired limit. The melting point of the transmitting medium is chosen to be the maximum temperature to which the frozen food may be warmed before sale, and the dye is preferably of the kind used in ball point pens. Specification 1,039,999 is referred to.

Title: Display device which changes colour and display method
IPC: G09F9/30
Filed: 1974-08-20
Abstract: 1481430 Controlling light OPTICAL COATING LABORATORY Inc 20 Aug 1974 [17 Sept 1973] 36584/74 Heading G2F In a display device, a material which becomes optically scattering in response to an applied electric field, e.g. a nematic or cholesteric liquid crystal material, is disposed between a reflector and a dielectric mirror which reflects a first colour and transmits a second colour. Where no electric field is applied, the two colours recombine after reflection to form the original colour of a light source used to illuminate the display. Where a field is pre-set the second colour is scattered and not directly reflected back to a viewer. The viewer may be positioned so as normally to see the reflection of the light source, so that an image of the first colour on a ground coloured as the, white, light source is produced. In other viewing positions the image has the second colour and the ground is generally white due to ambient lighting. If the reflector is wavelength selective, e.g. a second dichroic mirror on an optical absorber, the colours are modified. For example with a blue, B, reflecting, yellow, G + R, transmitting first dichroic and a magenta, B + R, reflecting, green, G, transmitting second dichroic, the background is magenta and the image is blue or orange, the yellow beam with a green depleted component, depending on whether or not the viewer normally sees the reflected light source. Different areas of the device may have dichrois with different spectral characteristics, such areas being sufficiently large to be identified as areas of different colour, or sufficiently small so that light from adjacent areas or dots if different colours appears as the additive mixed colour to the eye. Where the reflector is not wavelength selective it may comprise a metallic sheet, or a metallic film or a substrate, and may serve as one electrode.

Abstract: 986,466. Labelling machines. GEO. J. MEYER MANUFACTURING CO. Sept. 18, 1963 [March 26, 1963], No. 36745/63. Heading B8F. Relates to labelling machines of the kind in which labels are taken from a magazine by an adhesively-coated picker comprising two blades disposed edge-to-edge in the same plane and, with a label thereon, adapted to separate by movement in that plane to permit passage therebetween of a suction pad which takes the label from the picker blades and applies it to an article. According to the invention the picker P removes a label from the magazine M while its blades are closed and swings to a position in which the label is clamped between the picker P and a pressure pad 50, Fig. 2, so as to prevent movement of the label in its own plane as the picker blades separate. On completion of the separation and with the label held by its edge portions on the gummed blades 30a; 30b, Fig. 8, the pad 50 swings away to an inoperative position and the picker P moves to a transfer position, Fig. 3, to permit a suction pad 24 to take the label and apply it to the article B. As the pad 24 contacts the label with the article B, suction is broken and the pad connected to air pressure to ensure positive transfer of the label to the article. The pressure pad 50 is also provided with suction orifices which are operative when in contact with the label on the picker. In order to prevent application of excess gum to the picker or the application of gum to the pad 50 when, e.g. the machine, although running, is not receiving articles to be labelled, means, Figs. 10, 11, 12, (not shown), are provided which prevent the picker from entering the magazine or contacting the pad 50. This means is controlled by a detector-actuated switch which indicates that no article is present on the conveyer at the detecting point.
