Abstract: 1462303 Making cigars SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES 11 Jan 1974 [12 Jan 1973] 01482/74 Heading A2C Cigars and similar elongate smokable products are characterised by an interior formed from prepared fragments of natural or manfactured tobacco leaves such that at least one line parallel to the longitudinal axis of the product encounters a number of fragments along the length of the product, the major number of the said number of fragments being inclined to said line and at least 30% of the major number being arranged substantially normal to the line. Apparatus for making such cigars may comprise means for feeding in a regular manner fragments of sheets of tobacco for the interior of smokable products, means for putting metered amounts of fragments into the form of a uniform roll so as to impart to the roll a density which is lower than that reguired for the completed product, means for compressing the roll and means for enclosing the roll after compression to at least the required density in a wrapping which maintains the fragments thus assembled in a coherent manner, the means for putting the fragments into the form of a roll being adapted to operate cyclically or continuously. As shown in Figs. 1 and 2 an agitator 15 is movable or fixed and may be placed in a tank 10, the agitator comprising vertical cylindrical rods 16 having a substantially elliptical crosssectional shape. These rods stir the mass of interior tobacco which fills the tank and counter any tendency for fragments to accummulate flat on top of each other, and facilitating their descent to groove 22. Length of groove 22 corresponds to the amount of tobacco required to fill a small whole number of cigars (e.g. 1 or 2).

Abstract: 608,054. Lifting-jacks. DOWTY EQUIPMENT, Ltd., and BARBER, M. FOUNTAIN-. Feb. 17, 1947, No. 1672/46. [Class 78 (iii)] [Also in Group X] A hydraulic jack comprises a hollow ram 5, the inner end of which works as a piston in a cylinder 8, the ram acting as a reservoir for liquid which is pumped into the space 23 to extend the prop by means of a pump 13 and valves 18, 22, all housed in the inner end of the ram. The pump is actuated by a lever 14 inserted in a slot 16a in the ram, passing through an aperture 16 in the pump rod 17 and working in a bearing 15 secured in the ram 5. A relief valve 26 limits the pressure which may be set up in the space 23, continued pumping thereafter returning liquid to the ram.. A relief valve 27 allows the jack to yield under a predetermined load. A release valve 32 is provided to allow the ram to collapse for removal, actuated by a rod 31, the upper end of which extends into a hollow guide 34 extending transversely of the upper end of the ram 5 and engages a wedge member 30 urged by a spring towards the right in Fig. 2. Displacement of wedge member by a pull on the hook 29 moves the rod 31 down, opening the valve 32. The guide 34 also houses a valve 24 which allows air to enter the ram 5 to replace liquid pumped into the cylinder 8. Excess pressure in the ram set up when the jack yields (when used as a mine prop for example) may be relieved by opening the valve 24 which is accessible at 33. After the jack has yielded or collapsed a certain amount, the slot 14a becomes masked by the cylinder 8, preventing insertion of the handle 14 and hence erection of the jack in a condition in which there would be insufficient provision for yielding or collapse for subsequent removal. A sleeve 12 limits the extension of the prop.

Abstract: 777,113. Baling-presses; filling bags. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 15, 1954 [Jan. 20, 1954], No. 1686/54. Class 94(1). Fibres of polyethylene terephthalate coming from staple cutters are slightly compressed between conveyers 1 to a density of about 2 lbs. /cu. ft. and fed into a weighing hopper. Each weighed charge is fed by a ram 3 into a rectangular compression chamber 4, the ram forming the top of the chamber when in its lowered position 3A. A second horizontallymovable ram 5 then comes into operation to force the precompressed fibres into an exit passage 11 defined by converging guide plates 12 and 13 which are adjustable by a screw 18, further compression taking place between the ram and a plug of previously-compressed fibres 10. The ram 5 makes four strokes to form a bale having a density of approximately 25 lbs./cu. ft. in the passage (corresponding to 20 lbs./cu. ft. after expansion on leaving the machine), retrograde movement of the fibres on the return strokes being prevented by spring- loaded fingers 14. The head 6 of the ram is formed with slots 7 which accommodate the fingers in their projected position and allow the passage of binding wires 15 which are projected across the passage by a hydraulically-operated gate 19. After tying, the completed bales are ejected into bags placed over the ends of the guide plates. The rams may be operated hydraulically or pneumatically, and the ram head 6 is fitted with rollers 8 running on tracks 9 to facilitate its movement.

Title: Composite expanded plastics
Inventor: STASTNY FRITZ
IPC: C08J9/35
Filed: 1963-01-15
Abstract: An expanded resinous material consists of porous thermoplastic particles the interstices between the particles being filled with a foamed cured synthetic resin.  Spherical porous particles of less than 10 mm. diameter may be prepared by incorporating a volatile liquid within particles of polyvinyl chloride, polyethylene, poly(methyl methacrylate), polyurethanes, polyethers, polystyrene or styrene copolymers with butadiene or acrylonitrile and heating the particles above the boiling-point of the liquid.  Specified hardenable foamed synthetic resins are urea/formaldehyde, phenol/formaldehyde, melamine/formaldehyde, or polyurethane resins. These may include a surface-active agent and a curing agent.  In preparing the material the particles should be tightly packed and the foam added to it.  Fillers, e.g. granulated cork, asbestos or fibre waste may also be added.  The material may be prepared batchwise by placing particles in a mould with closed side walls and a perforated upper closure, which allows air to pass through but prevents escape of the particles, and introducing the foam at an inlet in the lower part of the mould.  The material may then be set in the mould or conveyed elsewhere.  In a continuous process particles fed into chamber 2 from hopper 1 are carried by screw 3 to inlet 4 where the foam enters.  More plastic may be introduced at a second inlet (not shown) in pipe 5.  The foam may be agitated or vibrated and a pressure difference may be used to convey it along the pipe to the site where it is to be solidified.  The product may contain 5-95% of the porous resin particles and may be coated, e.g. with asbestos.  It can be used to make shaped articles, e.g. structural units or heat insulation.  In Examples 1 and 2 particles of expanded polystyrene are mixed with a foamed urea-formaldehyde resin in the apparatus shown.  In (1) the particles are expanded with sodium diisopropyl-naphthalene sulphonate, phosphoric acid and air.  In (2) oxalic acid was added to the resin.  In (3) polyvinyl chloride particles were incorporated into a polyether prepared from pentaerythritol monoglycidyl ether, 4 : 41-diamino-3 : 31-dimethyl-dicyclohexylmethane and H2O2.
