Each scraper bar consists of front and rear plates interconnected by gusset plates 29. A pin 28 secured in apertures in the gusset plates receives a loop 26 welded to a vertically arranged link of the associated chain. The chains are guided within channels 30 welded to the underside of the plate 12, a grooved member 32 in each channel receiving the vertical links of the associated chain, the upper portions of these links being arranged within a slot 18 in the plate 12. Downward extensions 20, 21 of the scraper bars also engage in these slots to guide the scraper bars. Apertures 70 in the base of each channel 30 allow dust passing through the slot 18 to fall to a lower plate 14 along which it is propelled rearwardly by the scraper bars on their return run, the dust being returned via a plate 74 to the upper run at the receiving end of the trough. A plate 74a covers the conveying run in the vicinity of the plate 74 and the adjacent end sprockets 34, 35 which are separately adjustable for tensioning the chains. The opposite end sprockets 36, 38 are secured to a common shaft 46 which is driven by a motor 55. In order to guide the material into the narrow discharge end of the trough which has vertical side walls 62, walls 64 of increasing slope are provided between the walls 62 and the walls 60 and a camming block 66 is fitted immediately in advance of the discharge portion between the walls 62 to cam upwardly any lumps of material which would otherwise cause jamming. A heavy chain 80 is suspended between the walls 60 to break down large accumulations of material. In a modification, Figs. 8 and 10, the walls 64 are substantially at right angles to the walls 62 and a control plate 81 is provided above the path of the scraper bars to relieve the pressure on the material as it passes to the discharge portion and to smooth out the flow. Plate 81 has a portion 82 between the paths of the scraper bars, narrowing to a waist 83, and the remainder overhangs the scraper bars, gradually covering more of the paths. A stiffening plate 84 maintains this overhanging portion rigid.

Inventor: BALDOCK HUGH CHARLES
IPC: B21C1/26
Filed: 1965-06-23
Abstract: 1,116,901. Making seamless tubes; drawing tubes; expanding tubes. G. A. MITCHELL. 23 June, 1965, No. 26663/65. Headings B3A, B3J and B3P. A method of making a drawn tubular product from a tubular bloom includes the steps of expanding the bloom 14 around and along its axis of generation, excluding one axial end portion thereof, inserting said excluded end portion through a die aperture 12 sized intermediate said excluded and expanded bloom portions, and then drawing the remainder of the bloom through the die aperture. The bloom 14 is initially supported by clamps 16 and is expanded by a tapered plug 20 which is forced into bore of the bloom 14 by a push rod 22, axial movement of the bloom being prevented by a stop plate 18 positioned between the die 12 and the bloom. When the plug 20 has expanded the majority of the length of the bloom the stop plate is removed and further movement of the push rod 22 causes the unexpanded end portion of the bloom to pass through the die 12. This end portion is then gripped by the draw carriage 28 and the bloom is drawn through the die 12, the plug 20 remaining in the bore in the bloom and acting as a floating mandrel. This work cycle may be repeated using a larger plug 20 until the desired wall thickness is reached. The push rod 22, which is mounted on a push carriage 24, and the draw carriage 28 are both operated by a hydraulic piston and cylinder 32 acting through cables 48 and 66. The draw carriage 28 and push carriage 24 move in unison towards and away from the die 12 by means of a cable connection 58.

Abstract: 1,195,194. Automatic control. NATIONAL RESEARCH DEVELOPMENT CORP. Sept. 15, 1967 [June 17, 1966], No.27198/66. Heading G3R. In an automatic control system, a system variable and third or higher time derivatives of the variable are applied periodically to re-set a fast acting model of the system, and a comparison of the senses of the corresponding model variable and its derivatives determines the instants at which the model is re-set as well as the sense in which the system is adjusted. As applied to maintaining the course of an aircraft along a radio beam by automatic control of ailerons, signals corresponding to aileron deflection, roll attitude, heading error and displacement from the beam are applied to a computer 28, Fig. 2. The displacement from beam signal corresponds to a variable of the aircraft control system and the other signals to its first, second and third derivatives. Within the computer these signals are applied periodically to set successive integrating stages of a fast acting model of the aircraft control system so that its variable and derivatives correspond periodically to those of the aircraft control system. Between settings, products of the senses of the model variable and each of its derivatives are compared with the aid of logic or digital circuits so that the model is re-set and the sense of its input reversed each time all the products become positive. Also whenever all the products have become negative, at least momentarily, in succession starting from the highest derivative, the control signal D applied through an integratorlimiter 29 to the aircraft control system is made to correspond in sense to that applied to the model. This signal controls aileron servomotor 21 together with a phase-advanced stabilizing signal from a roll rate gyro 25, and a follow up signal from a tachometer generator 27.
