Title: Improvements in pouch shaped containers
Inventor: SMITH ERIC WALTER
IPC: B65D30/00
Filed: 1957-08-07
Abstract: 844,460. Cartons; pouches. ROSE BROS. (GAINSBOROUGH) Ltd. Aug. 6, 1958 [Aug. 7, 1957], No. 24870/57. Classes 18 and 133. In a carton made by folding a blank to U form and sealing together extensions 9a, 9b of opposed side walls to form end walls, tabs extending from the ends of the base 8 are creased at 45 degrees to the adjacent base edge along lines 5, 6, and the creases are joined by cuts 7 at right angles to said edge. This enables the tabs to be folded beneath the portions 9a, 9b, the lower edges of which then coincide with the end edges of the base. The blank used may be of paper sandwiched between layers of heat scalable film, the latter extending beyond the paper, to facilitate sealing.

Abstract: 404,761. Automatic exchange switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, PUCKETTE, C. C., and ROSE, W. R., c/o General Electric Co., Stoke, Coventry. Sept. 13, 1932, No. 25456. [Class 40 (iv).] The driving mechanism of a bi-directional step-by-step switch comprises two similar assemblies each consisting of a frame 1, Fig. 1, carrying an electromagnet 2 and an armature 3 on which the driving pawl 9 is pivoted, the frame being extended into an arm 5 formed with stops 6, 7 for the pawls. The pawl is advanced by a spring 12 when the armature is attracted. In a slightly different arrangement the pawl is bent instead of flat and the stops are made as a separate member screwed to the arm 5. Each assembly is fixed to the mounting, Fig. 4, by screws through the underside of the frame 1, the vertical magnet assembly being situated at 25 and the rotary magnet assembly at 40. The vertical ratchet 21, Fig. 3, is pivoted at 20 and carries on its extending arm 19 a pin 18 engaging a grooved collar 17 on the switch shaft 16. The rotary ratchet 30 is carried by a shaft 32 which carries also a sprocket 31 meshing with a sprocket 33 on the switch shaft, the length of 31 being such that the two sprockets always remain in mesh. Holding members 23, 38 are provided for the two ratchets, and these are interlocked at 39 so that both are withdrawn by the release magnet armature 28 while only 38 is withdrawn by the rotary release magnet armature 37. The shaft is restored rotarily by a helical spring housed within the sprocket 31, and a cam 35 co-operating with a toothed member 34 prevents the vertical return until the rotary normal position is reached. The mounting frame comprises a channel-shaped member 44, Fig. 4 completed by strips 45, 46, apertures being provided for the shafts 16, 32, and the switch as a whole slides into a channel forming part of the exchange racks. The relays and condensers are mounted above or below on a separate plate which may be fixed to the frame 44, while the terminal banks may be disposed above and below the frame, so that the shaft 16 may have wipers at each end. The various contact spring sets are mounted parallel to one another beneath the frame 44. Specification 349,180 is referred to.

Abstract: 277,820. Croft, F. Feb. 11. 1927. Expanding -pulley gearing comprises a driven pulley with deformable continuous band tread d, Fig. 1. and a main drive belt 5 which is kept in tension by an adjustable weight device. The tread band d rides between cones 2 one of which is movable by a lever 8 to vary the speed imparted to shaft 3 from a motor shaft 7a. The band, which is shown at d fully opened out, is shown at d<1> in interrupted lines when the movable cone has been opened out to transmit a higher speed. A jockey pulley 13 is biased by an adjustable weight 16 to tension the belt 5. In a modification, the belt 5 passes between two jockey pulleys moved oppositely by a weighted lever. In a further modification shown in Fig. 7, tensioning of the belt 5 is effected by raising the motor 7 bodily. For this purpose, the motor is supported upon screw legs 18 which are geared together by a chain 20 and are biased by a weight 16<b> in a direction to raise the motor. The movable pulley flange 2 is controlled by a lever 8<b>, Fig. 5, which moves over a fixed guide bar 17 and is locked thereto in adjusted positions by a screw clamp 8<c>.

A noble metal layer 1, of a platinum group metal, gold or silver or alloy of such metals is separated from a layer 2 of base metal, such as nickel, brass or stainless steel by a barrier layer 3 of fused alumina or zirconia substantially free of silicon compounds, although CaO and SiO2 may be present in an amount less than one per cent.  For a gold or silver layer more than one per cent of silicon compounds may be present in the barrier layer.  To form the composite material the surface of one layer is roughened by sand blasting and is sprayed with molten oxide for example by introducing powdered oxide in an oxyacetylene or oxyhydrogen flame. A crucible 4, Fig. 2, is made by forming cup members 5, 6, of noble and base metals respectively and coating either the outside of the member 5 or the inside of the member 6, or both, with fused oxide and then nesting the two members.  A container for molten glass comprising a pot 7, Fig. 3, in a ceramic body 8 is made of a thin liner 9 of platinum nested in a similarly shaped nickel support 10 with a fused refractory oxide layer 11 therebetween and a layer 12 of fused refractory oxide on the support 10 between it and the body 8.

Title: Improvements relating to the discharge of biscuits from wire mesh oven bands
IPC: A21B1/48
Filed: 1935-09-17
Abstract: 462,909. Endless - belt conveyers. ANCIENS ETABLISSEMENTS A. SAVY, JEANJEAN, ET CIE, and BAKER PERKINS, Ltd. Sept. 17, 1935, No. 25802. Convention date, Sept. 21, 1934. [Class 78 (i)] Biscuits which have been baked on a wire mesh or like perforate conveyer band 13 are freed therefrom, immediately on leaving the oven and while still hot, by means, such as the bristles of a brush, which project through the wire mesh and momentarily raise the biscuit 14 therefrom. In the form shown in Fig. 7, the rotary brush 19 is mounted idly in vertically adjustable bearings 23 and is rotated by the engagement of the bristles 20 in the meshes of the conveyer 13. After the biscuit 14 has been raised from the conveyer it is momentarily held stationary by the bristles and is thus redeposited on the conveyer in a position slightly rearwardly of its original one. This effect may also be obtained by positively rotating the brush 19 at a peripheral speed slightly less than the linear speed of the conveyer band 13. Fig. 8 shows a modification in which the brush 29 is of flat form and is reciprocated vertically by a cam 30. In a further construction the bristles 20 are replaced by flexible or plastic material which is deformed by pressure against the conveyer to provide bosses or projections which penetrate the mesh and detach the biscuits.
