Title: Automatic feeder for pulverulent material
IPC: G01G21/00
Filed: 1963-09-24
Abstract: 1,024,638. Screw conveyers. NISSON KAGAKU KOGYO KABUSHIKI KAISHA. Sept. 24, 1963 [Sept. 24, 1962], No. 37626/63. Heading B8A. [Also in Division G1] An automatic feed weigher has main and dribble screw feeders 20, 10 (Fig. 1) respectively, coaxially disposed, and a screen 12 (detailed Figs. 5, 6, not shown) prevents the passage of pulverulent material when rotation of the screw feeders is terminated. Means including a weigh beam 45 carrying a weight receptacle 44, by actuating a limit switch 46, controls through solenoids 33, 38 respectively a friction clutch 36 and a brake block 39 on the main screw feeder hollow drive shaft 5, for instance to disengage the clutch and engage the brake to stop the main feed at a predetermined weight value, while a dribble feed continues. When a required load is in the receptacle the limit switch disengages a similar solenoid operated friction clutch 28 on a dribble screw feeder shaft 4 and simultaneously applies a solenoid actuated brake block 31 to stop the dribble feed. Operation.-Material is fed through an inlet 1 to a tank 2 and undergoes a compacting pressure by a revolving pressure plate 17 (detailed in Fig. 3, not shown) and is acted upon by rotating mixer blades 19 before passing to the screw feeder 20. Some of the material in the tank 2 is scooped by blades 42 into a storage tank 18 for the dribble feed where it is acted upon by mixer blades 9 and passes to the inner screw feeder 10. The inner shaft 4 is also hollow and provides a vent 13 for the intake of air which prevents the raising of dust. A vent 3 is provided on the tank 2.

Abstract: 328,547. Connemann, W. Nov. 23, 1928, [Convention date]. Manures.-A process for preserving meat orfish waste, shrimps, &c. for use as manure or food for animals consists in drying the material by admixture with quicklime calcined gypsum &c., and mechanically separating the hydrated lime from the dry material, such as by screening. The material may be partially dried by heating before or after the addition of lime, and the screened material may be treated with carbon dioxide to convert any unremoved lime to calcium carbonate, for example by passing waste furnace gases through the material.

The numerals in brackets refer to the embodiment shown in Fig. 1 in which the anvils are surrounded by flat, annular, buttressing rings 38, 40, and the core is supported by a series of similar rings 32, 34, 36.  Additional rings 42, 44 and 46 may be provided where it is desired to cool the apparatus, and ducts 64, 66, 68 and 70 are provided for the supply and withdrawal of a cooling liquid to annular zones 56, 58 defined by means of rubber rings 48, 50, 52 and 54.  Fig. 3 shows a construction of the pressure chamber, adapted to be used with a sample 77 which does not conduct electricity.  A heating resistance 100 in the form of a cylinder is provided to form an electrical connection between the anvils 12, 14. Electrically conducting pads 102 are also provided, and insulating pads 106 and an electrically insulating tube 108 immediately surround said sample.  The faces of the anvils are covered with metal shims 104 to improve electrical contact and for protection.  In another embodiment (Fig. 4 not shown), an electrical resistance element in the form of a rod passing through the sample is illustrated.  Fig. 6 shows an arrangement adapted for use with a conducting sample. A cylinder 88 of conducting material having an end flange 96 is provided in direct contact with the charge, the space 92 being filled, e.g. with pyrophyllite.  Fig. 7 shows a modified core ring in which the inner part 72 comprises an insert 72 of refractory material such as sintered alumina which can be removed and replaced when necessary.  The apparatus is suitable for use with pressures up to 80,000 and temperatures up to 1800 DEG C.  The ring and anvils are made of refractory materials such as cemented hard-metal or tungsten carbide containing cobalt; the buttressing rings may be of high tensile steel and are force fitted or shrunk on to one another; the electrical element 100 and the pads 102 (Fig. 3) may be of tungsten, molybdenum or graphite.  The pads 106 and the tube 108 may be of refractory oxides such as alumina, zirconia or silica or may be of pyrophyllite.  It is stated that coating the operative faces of the <PICT:0922619/III/1> <PICT:0922619/III/2> <PICT:0922619/III/3> <PICT:0922619/III/4> anvil and covering with a high friction abrasive material such as rouge, or impregnating the body 74 with rouge is beneficial.  It is stated that the body 74 may comprise an outer part of high-friction material such as pyrophillite and an inner part of material not capable of supporting high shear stress such as talc or silver chloride.
