Abstract: 1360256 Weighing apparatus KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN NV 9 Sept 1971 [10 Sept 1970] 42159/71 Heading G1W To provide a substantially uniform flow of loose bulk material, e.g. wet ore pellets to a baking plant, from a fluctuating supply, the speed of a single conveyer belt 2 carrying the material from one or more supply stations to a delivery station is controlled in accordance with the weight flow of material carried by the belt, measured at or adjacent the delivery station. A signal from a weighing scale 5, which includes a tachometer, represents the weight flow delivered by the belt 2, being the product of weight and belt speed measurements. This signal is passed through a high permeable filter 6 having a time constant between 30 and 60 minutes, the output signal representing fluctuations of the flow about a measured average value. After passing through a proportioning regulator 7 the signal is added at 8 to a constant signal representing the belt speed for a desired average belt load, the resultant signal controlling a speed adjuster 9 which regulates a D.C. motor driving the belt 2. Finely powdered ore is formed into pellets in a forming drum (1) Fig. 1 (not shown) which feeds the conveyer (2). From the conveyer, the pellets drop on to a chain grate (3) which travels through a baking furnace.

Abstract: 1359019 Sedimentation tanks SHERRITT GORDON MINES Ltd 16 Sept 1971 [30 Sept 1970] 43325/71 Heading B1D [Also in Division G3] A settling apparatus comprises a tank 12 with inlet 42 via feed well 43, clarified liquid outlet 29 and sludge outlet 14, the tank having a conical interior bottom 28 and containing a rotary rake assembly 32. The rake assembly is mounted on a shaft 36 in bearings 35 so that it may both be rotated by fluid operated motor 50, and also may be raised or lowered vertically, by piston 63. The motor and piston are connected in a fluid circuit such that if the load on the rake assembly and hence the motor increases then the rake will be lifted vertically to lower the load thereon. Hence the vertical position of the rake is responsive to the load thereon. If the load on the rake increases then the motor 50 will slow and the pressure in the fluid supply line for the motor 52 will consequently increase. This will result in an increase of pressure at 66 below the piston and will hence raise the piston this having the effect of reducing the load on the rake and hence the pressure in the fluid supply line. A pressurised air source 68 is connected to the space 65 about the piston to act as a buffer and to force the piston and rake down if the pressure in the fluid supply line falls. The outgoing fluid from motor 50 is passed through a further hydraulic motor 60 which is coupled to diaphradgm pump 20 controlling the sludge outlet rate from the tank.

Abstract: 926,942. Fabrics composed of adhesively bonded filaments. AMERICAN AIR FILTER CO. Inc. Dec. 21, 1960, No. 43872/60. Class 74 (2). [Also in Group IX] A method of making a mat comprises winding a plurality of cylindrical mats, each formed of a number of layers of filaments, and having outwardly tapered end areas; axially slitting the mats to form planar mats; positioning at least two of the mats in parallel, spaced-apart relationship; stretching one of the mats in a plane perpendicular to the general lay of the filaments; stretching the leading tapered end of another mat simultaneously with the trailing tapered end of the first mat ; and feeding both the leading and trailing tapered ends in overlapping relationship through a treating zone. Continuous glass filaments 6 are drawn from a traversing furnace 4, collected into cords by a wheel 24 and fed by a wheel 26 to a rotatable drum 2. The furnace 4 is carried by a framework 8 having rollers 10 which run on rails 12 and is driven by a pin 20 on an endless chain 16 driven by sprockets 14. Auxiliary drive means 22 is provided for progressively shifting, first in one axial direction and then in the opposite axial direction, the path of the furnace 4 relative to the drum 2. Wheels 30, 32 carried, together with the wheel 26, by a rod 28 depending from the framework 8 feed collected cords of glass filaments from other sources. The means 22 includes a plate 40 secured to the framework 8 and having a channel member 44 carried thereon by blocks 42. A driven cylinder 48 having right hand and left hand helical grooves is journalled in blocks 46. An element on a block 56 projects into these grooves, the block 56 being mounted on a carriage 50 having legs 52 movable in the member 44 by wheels 54. The carriage 50 has a bracket 61 secured thereto and which has a slot 63 in which the pin 20 slides as it traverses the sprockets 14. The reversal position of the furnace 4 relative to the drum 2 is partly determined by the position of the carriage 50 on the cylinder 48, partly on whether the sprockets are eccentrically or concentrically mounted and partly on the length of the row of the orifices of the furnace 4. The cylindrical mat formed on the drum 2 is slit axially and two such mats 62, 64, Fig. 6, are laid on tables 66, 68, respectively. The mat 62 is stretched and the leading tapered end of the mat 64 is laid on the trailing tapered end of the mat 62 whilst it is being stretched and treated so that a composite area is formed. This is repeated so that a web 70 is formed which is passed on a conveyer 72 into a receptacle containing a binder liquid 74, flattened with a roller 76, passed over a suction device 78 to remove excess liquid and passed through an oven 80 in which the liquid in the web is treated and wound into a roll 82.
