Abstract: 1,016,314. Cartons; compartment inserts. REED PAPER GROUP Ltd. Sept. 1, 1964 [Sept. 4, 1963], No. 34964/63. Heading B8P. A blank of cardboard, which may be corrugated, for forming a compartmented insert for a container comprises a series of partitions-forming strips e.g. 21, Fig. 3, sub-divided into portions 24, by cuts 20 or by gaps, and hingedly connected to a series of wall-forming strips e.g. 16, 17 by perforation lines 27. The wall-forming strips are arranged in echelon fashion. The edges of the partitioning portions are partially released from the wall-forming strips by cuts 26, and the acute-angled corners 29 separated by perforation lines 28. The blank is erected, Fig. 7, by turning the pairs of wall-forming strips in the same clockwise sense about the edges of their corresponding partitions-forming strips, so that the portions 24 extend from the top of one wall 16 to the base of the other 17; and displacing successive wall-forming strips in the same longitudinal direction relative to one another to bring the connected parts 29 of the partitions-forming strips into approximate alignment. Portions 29 are glued to the walls, and the erected insert may be folded flat for storage. In an alternative embodiment, in which no gluing is necessary, the strips are hingedly connected by crease lines and the perforation lines 28 are omitted. In another embodiment, Fig. 1 (not shown), in which the strips are connected by crease lines, and alternate wall-forming strips are displaced in opposite directions, when erecting the insert, to align the connected parts of partitions-forming strips. The partitions-forming strips are not glued to the walls.

IPC: B21J5/00
Filed: 1930-11-20
Abstract: 357,855. Casting ; forging; shearing. FORD MOTOR CO., Ltd., 88, Regent Street, London.-(Assignees of Ford, H. ; Dearborn, Michigan, U.S.A.) Nov. 20, 1930, No. 35015. Convention date, Nov. 20, 1929. [Classes 83 (i) and 83 (iv).] Casting-machines; metal-pouring; moulds; castings; castings, extracting.-Castings for subsequent trimming and forging are made of uniform size by pouring metal in slight excess into moulds carried by a conveyer chain so that the moulds are completely filled, excess metal flowing to the following mould. Trimming and forging operations follow while the casting heat still remains in the blanks. A ladle 10, Fig. 3, brought by crane from a converter or hearth furnace to the machine, or a tiltable furnace, is manually rocked by a screw 54 to pour metal to moulds 32, Fig. 6, trunnioned on a double conveyer chain 28, excess metal being directed by an apron 34 on each mould to that following. The chain runs over sprockets 18, 20 to a sprocket driven by an electromotor and is guided along tracks 56, 22, &c. by strips carried on the framing bearing on the upper surfaces of the moulds. When the moulds have moved sufficiently far for the ingots to solidify, they strike a rod 40, Fig. 4, and the end of a track 41 so that they are reversed and move under a helve 42 vibrating under the control of an electromotordriven shaft 48, eccentric 49, and resilient means 46. The ingots are thus ejected and descend a shoot to a second conveyer by which they are conveyed, while still hot, to the trimming and forging presses. Stationary gas jets are provided to preheat the moulds and their conveyer chains.

Title: Improvements in or relating to the manufacture of cylindrical bodies of plywood
IPC: B27D1/08
Filed: 1936-12-21
Abstract: 492,738. Making cylindrical bentwood articles ; casks ; tubes ; boxes. LUSTY & SONS, Ltd., W. Dec. 21, 1936, No. 35126. Void. Convention date, Dec. 21, 1935. [Class 145 (ii)] [Also in Groups XVII and XXVIII] Cylindrical bodies, such as casks and tubes, formed of bent superposed sheets of wood, such as plywood, glued together under pressure in a cylindrical former, are constructed with helical joints between the meeting edges of each sheet. The sheets 15, Fig. 1, are cut with parallel sides J9, 20 oblique to the remaining sides so that when the sheet is bent to a cylindrical form the edges 19, 20 meet to form the helical joint. A number of sheets 15a, 15b, 15c are assembled, after glueing, in a two-part cylindrical mould 18, 18a, which may be provided with conduits 25 for heating fluid, and end pressure is exerted on the sheets by end plates 21, 22. This causes radial expansion of the shells owing to relative sliding at the helical joints of the meeting edges, the pressure necessary for the glueing being thus produced. Fig. 8 shows a construction of cask in which the end is formed of superposed discs 17a, 17b, 17c, the outer of which is of greater diameter than the others and overlaps the end of the body, being secured by loops or rings 30, 31. An annular space 32 round the edge of the disc 17a may be packed with rubber, cotton, felt, ductile metal or the like to form a safety joint, and a U-section metallic hoop 33 may be pressed on to the end assemblage. The mould is provided with a metal packing member 33 formed by two semi-cylinders to occupy the space between the projecting end hoops. The construction of casks, boxes, &c., from one or more shells with either helical or straight bevelled joints in a mould having an internal cylindrical mandrel is also referred to, the pressure being produced by closing the mould or expanding the mandrel. Fig. 12 shows one shell of a section of a tube, the internal shells being successively displaced axially by their semi-length.

Abstract: 942,618. Feedwater supply systems. G. & J. WEIR Ltd. Sept. 13, 1962 [Oct. 3, 1961], No. 35690/61. Heading F4A. In a feedwater supply system wherein an extraction pump feeds condensate from a main condenser to a deaerator, main and standby feed pumps are provided, the suction of main pump being connected to the deaerator discharge whilst that of the standby pump is connected to the supply line from the condenser to the deaerator. Preferably, and as shown in the Figure, the two feed pumps 16, 17 are similar and feed into a common supply line 26, the suctions being provided respectively with valves 18, 22 and 19, 23 whereby either pump can serve as the main pump. For example, if 16 is to serve as the main pump, the valves 18, 23 are opened and the valves 19, 22 are closed. The main pump then draws its water from the deaerator 11. If the pump 16 fails mechanically or loses its suction the standby pump 17 starts automatically, drawing its water from the line 12 from the main condenser 10 to the deaerator and in which sufficient pressure to ensure suction for the pump is maintained by the condensate extraction pump 13. If, with the standby pump operating, the boiler demand is such that the pressure in the line 12 falls a non-return valve 29 in a line 28 from a cold feed water tank 27 opens and the pump 17 draws its water both from the tank and the main condenser.
