Title: Improvements in and relating to means for folding and sealing the flaps of packages
IPC: B65B61/24
Filed: 1966-02-24
Abstract: 1,081,244. Re-shaping packages. TEPAR A.G. Feb. 24, 1966 [March 5, 1965], No. 8196/66. Heading B8C. Triangular flaps 3, 4, Fig. 1, produced during the formation of parallelepipedic packages from cushion-shaped packages obtained by the transverse sealing and severing of a filled tube, are partially folded down on to adjacent package end and side walls, adhesive is then applied to, or previously applied adhesive activated on, the flaps and/or the package walls, and the flaps sealed down. In the embodiment, the package 1, Fig. 1, is conveyed through the device in a holder 8, Fig. 2, comprising a fixed base 16, a fixed side wall 9, a side wall 10 pivotable about a shaft 13 and side walls 12, which terminate above the level of the base, pivotable about shafts 11. The base-plate 16 is provided with a notch 19 into which the sealing fin 2 is guided so that it is folded down as the package, with flaps 4 uppermost, is thrust into the holder. Before the sides of the holder are locked into position, means (22), Fig. 3 (not shown), pivotable about shafts (21) on the holder, bear down on flaps 3 to ensure that the package is pressed down into contact with the base-plate. The filled holder with flaps 3, 4 projecting from opposite sides, carried on a conveyer 50, then passes beneath a platen (24), Figs. 4, 5 (not shown), which is oscillated into contact with the upper end of the package to cause the flaps 4 to be partially folded up. Guide bars (not shown) continue this folding until the flaps are partially folded down over the top end wall, Fig. 6 (not shown). Simultaneously the flaps 3 run on to guide bars (29) and are partially folded up against the side walls. At the next station hot air from nozzles (30, 31) is blown against the flaps and adjacent walls to activate adhesive, e.g. a layer of plastics laminate. Thereafter, by continued movement along bars (29), the flaps 3 are completely folded and sealed to the side walls, Fig. 9 (not shown), the side walls of the holder being terminated above the base to allow sufficient area of the side walls of the package to be exposed. Meanwhile the flaps 4 are pressed down against the top wall by a pressure plate (47), Fig. 7 (not shown), or by a system of pressure plates (65), Fig. 8 (not shown) carried on a conveyer 60, one end of which is pivotable, the other end being operated on by a cylinder (67) and piston (68) to provide a constant compressive force. For a packaging material which is not plastics coated, the hot air nozzles may be replaced by devices for supplying adhesive.

Title: Improvements in thermionic converters
Inventor: KLEIN SIEGFRIED
IPC: H01J45/00
Filed: 1963-03-05
Abstract: 966,130. Thermionic generators. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 5, 1963 [March 5, 1962; April 6, 1962], No. 8757/63. Heading H1D. [Also in Division H3] The efficiency of a thermionic generator is improved by the addition of a fine wire emitter 20 of a material, preferably tungsten, having a higher work function than the normal cathode 14 to which at least it is connected, the wire being heated to a higher temperature than that of the cathode by electron bombardment and Joule effect. As shown, the wire is a single spiral connected to both cathode and anode, but alternatively it is a grid of crossing or undulating wires connected to the cathode only (Figs. 2 . . . 4, not shown). The generator comprises an annular trough 1 of platinum or nickel containing caesium or rubidium to produce a vapour to lower the space charge, the cathode 14 is of barium or strontium oxide formed on the surface 7 of the trough and the anode 5 is of " Kovar " (Registered Trade Mark), preferably coated with graphite at 27. The interrelation of these materials during operation is discussed in detail. A source 10, e.g. flame, solar radiation or nuclear power source, heats the cathode to approximately 1000‹ C., while the wire 20 operates at about 2000‹ C. The anode normally operates with caesium vapour condensed on its surface and to effect this it may be cooled by unspecified electrode radiator means. The generator may alternatively be evacuated, but then the cathode/anode spacing would be a tenth of a millimetre. There is also described an oscillator circuit (Fig. 6, not shown), including the thermionic generator but with an additional grid, whereby A.C. is produced at power frequencies.

Patent GB-622628-A (GB)
Title: Improvements in and relating to the production of chocolate and cocoa powder
IPC: A23G1/04
Filed: 1947-04-02
Abstract: Unroasted cocoa beans are steeped in water or an aqueous solution and comminuted to produce an aqueous bean dispersion and subsequently dehydrated and roasted.  The roasting may precede the dehydration. The unroasted beans, either in whole or crushed condition, are steeped in water or a suitable aqueous solution, e.g., a solution of potash, and are then finely divided to produce an aqueous bean dispersion.  According to one method, this is followed by dehydration and then kneading under heat to form a paste.  The paste is roasted by being passed as a thin film over heated rollers or through a high frequency electric field.  Cocoa butter may be added to the dehydrated bean mass before roasting.  The dehydration and roasting may be carried out simultaneously by spray-drying the bean dispersion in a hot gaseous medium, which may be air or combustion products.  As a further alternative, the roasting, which may take place in an autoclave, may precede the dehydration.  In any of the above processes, the bean dispersion, before dehydration and roasting, may be wholly or partly freed of cocoa butter by electrophoresis or centrifuging, or cocoa butter may be added.  The comminution of the beans may be carried out in such a way, as by rolling, that only the ribs are finely divided, the shells being torn into relatively big flakes.  The shells may then be separated, as by means of a sieve, after dehydration.
