Title: Apparatus for skinning beans
IPC: A23N15/12
Filed: 1959-08-19
Abstract: 880,440. Beans, skinning. GUY, E. G. Aug. 19, 1959, No. 28321/59. Class 28 (2). [Also in Group I] Broad beans are skinned by nipping one end to split the skins there and applying pressure to the flat side to expel the bean through the slit. Alternatively a bean pod may be slit by a hand knife along its back such slit including slitting of the backs of the inside beans and applying side pressure to each bean in turn while in the pod to expel the beans through their slits. Each bean is placed by hand on a roughened platform 2 with a separate smooth apron extension 17 swivelled about 20 to drop the skins away, as the bean is squeezed out on to this platform 2 and tipped away into a receptacle while the skins drop through the gap at 22 caused by the swivelling. The bean before skinning rests on two small linear depressions 23 in which lie the bent spokes 24 of a halfrotated spindle 26 which also has spokes 27 the ends 28 of which slide along grooves under the apron 17 to swivel it. The bean's end is nipped by the ends 10 of nipper handles 9 which are spread apart by squeezers 8 attached to the wheel 3 when the wheel 3 is semi-rotated by its cranked bar 4 in its bearings 5. The squeezers 8 are guided in cam guides 12 to close and then open the nippers on each semi-rotation. The bean is squeezed out by a compressor 31 with a rubber jacket 35 containing a core 34 pressed down by a cap 33 moved down by being coupled to the wheel 3 by a hammer handle 7 moved down by a bar 38 sliding in a groove 56 in the wheel rim. The bar 38 is provided with small nipples along its length. The bar 38 is slotted at 41 to allow the hammer 7 to pass freely through the slot 41 acting as a cam on the hammer to depress it. The sides 42 of the bar 38 and the sides 43 of the hammer 7 are padded to give resilience to allow for different thicknesses of beans. A stop on the inside of the wheel rim causes the compressor to be raised to rest position when the wheel is rotated back by hand. When the wheel 3 is hand rotated for a semicircle a wheel 46 is rotated by internal teeth 45 on an arc fixed to the wheel whereby spindle 26 is rotated to operate the bent spokes 24 so that they recede into the platform 2. To carry away the bean skins the spokes 48 of wheels 46 are so arranged to meet the bar 49 of a frame support 1 to stop the backward rotation of the wheel 3 so that it can no longer swivel the apron 17 which is now vertical. Meantime the spokes 24 have rotated into the position previously held by the spokes 27 and in rotating have carried forward the skin which remained on the platform 2 to fall through the opening. Two or more such machines may be combined and designed to suit varying sizes of beans.

Title: An improved process for producing mixed cellulosic esters
IPC: C08B3/16
Filed: 1936-10-19
Abstract: Mixed esters of cellulose are obtained by digesting an ester containing sulphuric acid residues as derived from the catalyst used for the esterification of such ester, with a liquid comprising at least one substance which contains at least one radicle of the kind to be introduced and chosen from fatty acids, esters of fatty acids and substitution derivatives thereof, the conditions of the digestion being such that the sulphuric acid residues are retained in sufficient quantities in the ester and that the latter is maintained throughout in the swollen condition. If desired, further quantities of catalyst may be added to the digestion liquid; and the latter may also contain a diluent.  The cellulose ester to be treated may be prepared by the heterogeneous or homogeneous method.  After the production of the mixed ester, sulphuric acid residues remaining therein are removed as by repeated treatment with water or other appropriate stabilizing agent.  In an example, cellulose acetate prepared by the heterogeneous method is washed with benzene and ethyl acetate, then digested with ethyl butyrate to produce the desired cellulose acetate butyrate, which is finally stabilized by repeated treatment with ethyl acetate.  Specifications 338,201, 338,202, [both in Class 2 (ii)], 360,058, 411,260, and 468,880 are referred to.

Inventor: THOMPSON JAMES GREER
IPC: A23L7/104
Filed: 1949-11-09
Abstract: A method of producing a ready-to-eat cereal product from oats comprises forming an aqueous mixture of oatmeal or other edible form of oats and heating preferably below 100 DEG C in the presence of an enzyme, preferably of a type capable of breaking down the starch in the oats into sugar, to form a sweet fluid porridge mixture, heating said mixture preferably above 100 DEG C to form a stiff paste and then subjecting the paste, preferably in finely divided form, to baking oven temperature to dry and bake into a crisp and puffed product.  The paste may be subdivided by extrusion in the form of rods or filaments which may be extruded on to a travelling mesh conveyer at a speed exceeding that of the conveyer to cause a wavy or sinous disposition of the rods.  The baking process may be effected by causing the conveyer to pass close to or between heating panels which may form part of a tunnel and which emit infra red rays.  In an example 9 1/2 lb. flaked oats, 1 1/2 oz. salt, 19 grms. enzyme preparation and 7,371 litres water are added in a water jacketed pan and mixed to a smooth consistency and stirred for 2 1/2 hours when it becomes thin and is then tipped into a steam jacketed pan and boiled until it is very thick.  The mixture is allowed to cool and is then dumped into a hopper mounted on a screw type extruder and forced on to a moving wire mesh belt conveyer which traverses a drying oven incorporating heating panels emitting infra red rays, the temperature of the oven being 400 DEG F at the feed and 200 DEG F at the exit.
