Title: Improvements relating to a method of and apparatus for transferring bulk material between zones at different pressures
IPC: A23L19/18
Filed: 1965-03-30
Abstract: 1,067,071. Pneumatic conveyers. GEBRUDER BUHLER. March 30, 1965 [April 1, 1964], No. 13404/65. Heading B8A. In apparatus for transferring bulk material between two zones at different pressures a sealed drum 10, Fig. 3, has at least two compartments 20 which are successively filled and emptied during relative rotation between the drum 10 and a feeder 6 and have inlet and outlet members 28, 29 carried by the drum 10 so that relative rotation between the drum and the closure members is avoided. In the example of Fig. 3 the drum 10 is rotatable below a fixed feed 6 of a separator collecting material from suction conveyer, a rotary seal 68 being provided for the feed support 7. Other examples, Figs. 7-11 (not shown), are described in which the sealed and compartmented drum 10 is stationary and the feed 6 is rotated to direct the material successively above the inlets of the compartments. In the example of Fig. 3, the inlet closure members 28 between an upper suction chamber 22 and the compartments 20 are opened successively under their own weight when cam-actuated valves 48 are opened to balance the pressure on opposite sides and are subsequently closed by atmospheric pressure on pistons 32 in arcuate cylinders 33 having cam-actuated inlet valves 40. Leakage apertures 38 are provided in the cylinders 33 so that on closure air enters the relevant compartment 20 to balance the pressures on opposite sides of the outlet closure 29 and release the material. The closures 29 are then successively closed by engagement of rollers 58 on cam tracks 57. In modifications (Fig. 6, not shown), the arcuate cylinders 33 are connected to a source of pressure air and in Fig. 11 (not shown), the lower closures 29 are also piston actuated. A system for removal of dust from the apparatus is described with reference to Fig. 12 (not shown), one of the valves (155) in an air lock device being piston actuated simultaneously with one of the inlet closures 28.

Title: Improvements in or relating to the Production of Boards, Building Elements, Columns or the like
IPC: B29C39/00
Filed: 1967-03-23
Abstract: 1,170,363. Moulding building elements. ANFI A.S. 23 March, 1967 [13 April, 1966], No. 13616/67. Heading B5A. Boards or building elements with a relief surface on one side are formed by filling a layer of non-hardening material into a mould, placing the required amount of aggregate on the non- hardening material, covering the aggregate with a setting plastics binder optionally mixed with finer graded aggregate, vibrating if required, and after the binder has set removing the element from the mould and flushing any adhering non-hardening compound from its surface. Various compositions are given for the non- hardening material which must not react with and should have a specific gravity greater than the binder. If the binding agent can harden in the presence of water (e.g. on epoxy resin) a layer of concrete may be formed in the mould before the binder has set. A layer of insulation, e.g. foamed polyurethane, may also be formed on top of any previous layers; this helps to take up irregularities between the element and the surface on which it is mounted. Reinforcing material, e.g. glass or natural fibre, expanded metal or metal melting, may be inserted in one of the layers during preparation.

Title: Skin-pack
IPC: B65B11/52
Filed: 1963-04-08
Abstract: 1,042,513. Packaging-machines. G. MISSBACH. April 8, 1963 [April 7, 1962], No. 13945/63. Heading B8C. In an apparatus for forming skin packs the operations on the packs are performed during continuous forward movement of the articles. In the illustrated embodiment, the articles 3 (Fig. 1, not shown) advance on a supporting layer 2 which is permeable to air, over a table 1 and thence around a drum 8 which rotates continuously. A covering plastics film 6 is fed over the articles, heated at 16 to plasticize it and then pressed on to the supporting layer 2 at intervals by a reciprocating pressure plate 17. Suction orifices 10 (Fig. 3, not shown) in the drum 8 are now uncovered by an internal elastic covered drum causing the covering layer 6 to be drawn skin tight over the articles. Thermoplastic adhesive applied to the layer 2 at 4 is activated by the heated covering film 6 causing the two to unite. The orifices 10 are again covered and the packages pass through a cooling zone. The thermoplastic adhesive on the layer 2, or ordinary adhesive moistened at 4, help to locate the articles accurately. If the articles are of a magnetic material, they may be retained by a magnetic force. The drum 8 may be of increased diameter at its ends to form an annular chamber 11 with guide surfaces 14 for the covering layer 6. The layer 6 may be held in contact with the surfaces 14 by two endless guide belts 15 or by vacuum applied through a plurality of inserts of porous material within the walls 13. Alternatively, the drum 8 may have a constant diameter throughout and the covering layer 6 be guided over the articles in a bell formation prior to the deformation. To aid this arrangement the layer 6 may be heated in advance, below plasticization point, prior to reaching the drum 8. The continuous web forming the supporting layer 2 may be replaced by individual sheets and the chamber 11 of the first embodiment is subdivided into lengths slightly longer than the lengths of the sheets by transverse walls which may be pivotably mounted on the base 12 by spring-controlled hinges to enable the table 1 to be brought close to the drum 8. The supporting layer 2 may be made of a cardboard inherently permeable to air or may be rendered permeable by perforations. To ensure uniform heating of the cover layer 6 and prevent damage of the articles 3, an insulating layer 22 is placed therebetween beneath the heater 16.
