Title: Improvements in or relating to vehicles for carrying bulk loads
IPC: B60P1/40
Filed: 1955-06-10
Abstract: 803,891. Screw conveyers on vehicles. [SMITH (MOTORS), Ltd., F. G., BAKER, H. C., and WARREN, E. H. June 6, 1956 [June 10, 1955; March 16, 1956], Nos. 16696/55 and 8271/56. Class 78 (4). Screws 10 (Fig. 3) feed material from opposite sides or ends of the body of a vehicle to a central discharge aperture 2 down which the material is impelled. In the construction illustrated a vane 11 pushes the material through the outlet 2 to a rotating pocket wheel 21 (Fig. 4) which delivers the material to a pneumatic conveyer 20. The shaft 7 of the screws 10 is mounted between plates 8 (Fig. 3), joined by a shroud 9 to form a unit which is held, when in use, between stops 12 (Fig. 4), on the walls of the vehicle and the tail gate 3 so that the unit may be removed and housed in a compartment (not shown) at the side of the vehicle. Alternatively the screws 10 and vane 11 may be permanently mounted in a trough at the rear of the body and covered by a flat plate, flush with the floor, when not in use. The shaft 7 is coupled to a pinion 15 on the outside of the vehicle by a removable key 17. The sprocket wheel 15 and the pocket wheel 21 may be driven from the engine of the vehicle. A hollow partannular shield 23 of triangular section, as shown in Fig. 3, covers the central portion of the shaft 7 and houses a pipe 26 serving either to permit air passing the paddle wheel 21 to be exhausted through a hole 27 in the floor of the vehicle or to conduct air bled at 28 from the pockets of the wheel 21 to assist in forcing material through the outlet 2. The outlet 2 may be closed by a gate (not shown) as also may an outlet 4 in the tail gate 3. Agitating members 31 on a shaft 30 in the body prevent the material from arching. Where the body tips it preferably tapers forwardly and it may be divided into compartments by lateral partitions which can be released to hinge about their upper edges so that each compartment may be emptied in turn. The partitions may be movable along the vehicle to vary the sizes of the compartments.

Title: Manufacture of dehydrated coffee
IPC: A23F5/26
Filed: 1945-07-02
Abstract: 594,845. Coffee. CLEVELAND, F. J. (Union Starch & Refining Co.). July 2, 1945, No. 16796. [Class 129] Solid dehydrated coffee is manufactured by extracting the coffee constituents of ground coffee with a corn syrup solution and dehydrating the resulting coffee corn syrup mix. An extraction liquor having a concentration of approximately 20‹ BaumÚ is made up of 150 lbs. of 43‹ BÚ regular corn syrup, 20 lb. of water and 300 lb. of washing from a previous run, and 350 lb. of it is delivered from a tank 2 into a percolator 1 containing 100 lb. of pulverized coffee beans. The mixture is circulated through the percolator by a pump 4 for one hour at a temperature below the boiling point, say 195‹ F. The extraction liquor, which contains both soluble coffee solids and volatile flavouring and aromatic constituents, is drawn off into a vacuum pan 5. The remaining 120 lb. of fresh extraction liquor is then run from tank 2 into the percolator to remove the remaining heavy residual extract and is added to the original extraction liquor in the vacuum pan, the BaumÚ of the combined liquors being about 23‹. Evaporation proceeds until the BaumÚ is raised to about 43‹, when the liquor is drawn off to a vacuum dehydrator 6, in which it is dehydrated to a cellular mass which can subsequently be pulverized. The residual coffee mass in the percolator is treated with 320 Ib. of fresh water, and the resultant extract is drawn off into tank 2 to form part of the extraction liquor for the next run, which takes place in a second percolator 7. Specifications 577,994 and 582,918 are referred to.

Title: Melt-spinning device for synthetic fibres
IPC: D01D13/00
Filed: 1972-04-13
Abstract: 1391844 Melt-spinning apparatus DU PONT OF CANADA Ltd 13 April 1972 [16 April 1971] 17148/72 Heading B5B In apparatus for melt-spinning filaments, molten polymer is supplied from a common source through transport means to a plurality of spinning packs, at least some of the spinning packs and transport means being mounted in or insulated vessel and heated in a common environment by heated vapour. As shown in Fig. 1 polymer is supplied from extruder 10 via pump 14 to transfer line 16 and thence to the independent spinning positions 17. Vessel 13 surrounds the transfer line 16 and spinning positions 17. As shown in transverse section in Fig. 5, transfer line 16 connects with manifold 41 and so with splitters 42 which distribute the molten polymer via feed lines 43 to the spinning packs 52. The manifold and transfer line assembly are kept at a constant temperature inside the insulated vessel 13 by vapour from the liquid heat bath 45. The spun filaments may pass down quench chimneys 27 to draw-twisting and finishing apparatus. Polyhexamethylene adipamide is given as an example of a polymer to be used in this apparatus. In Fig. 3 three inverters 37 are shown. These invert the flow of the molten polymer so that the outer one-third of the flow is directed into the centre of the pipe at each inverter. After three such inversions the "cross-section" of the flow is substantially the same as at the outset, but the lag covered by laminar flow is avoided and the polymer has substantially the same thermal history across this section. The same thermal history is maintained by careful positioning of the splitters, which remove the slower moving edge portion at the first, and the central feeder, portion at the last. This ensures that the polymer reaching each spinneret has had the same residence time.
