Title: Improvements in and relating to rolling mills for rolling metal sheet and strip
Inventor: FORD HUGH
IPC: B21B31/07
Filed: 1957-12-23
Abstract: 858,296. Rolling plastic materials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 18, 1958 [Dec. 23, 1957], No. 39946/57. Class 87(2). [Also in Groups XXII and XXIII] In a rolling mill for rolling metal plastics or glass comprising at least two rolls, hydraulic pad bearing means extends over a major part of the axial length of at least one of the rolls and bears against the working surface so that on displacement of the roll relative to the bearing, pressure changes occur in the pad which restore the roll to its undisplaced position. The backing rollers 6, 7 of a mill for hot or cold rolling metal sheet or strip are mounted in chocks 1 and 3 hinged together by pins 4 and standing on a base 2. Work rolls 8, 10 engage the backing rolls in slots 9, 11 and project from the chocks to form the pass which is adjusted by screws 5. Hydraulic pressure pads 13 and 17 are arranged around the working surface or periphery of the backing rolls, the pads 13 acting to maintain the pass constant while the pads 17 maintain lateral stability of the rolls, where there are no backing rolls the pads are arranged about the work rolls. The pads 13, 17 are supplied with liquid, e.g. lubricating oil or water from a pump 16 through constant flow controllers 15 so that when slight movement of a roller from its required position occurs leakage from the pads 13 is either increased or decreased resulting in a fall or rise of pressure in the pads which returns the roll to its undisplaced position. The pads 17 which work in similar fashion may modulate the thrust of the pads 13. The pads 17 may additionally be controlled by an error signal indicative of the strip guage. Ducts 21 leading from a constant flow controller 22 also supplied by the pump 16 or a separate pump maintains lateral stability of and supply coolant under pressure to the work rolls 8, 10 leakage occuring around the rolls to lubricate and cool the work. The liquid leaking from pads 13 bye-passes the pads 17 and is either led to the top of work-roll 10 and the bottom of work-roll 8 or direct to the work. Additional control of the pressure pads may be provided by pressure-sensitive ducts 23, Fig. 2 (not shown) which operate the flow controller 15 or alternatively means actuated in response to an error in the guage or means responsive to pressure changes in capillary ducts leading to the pressure pads may operate valves which control the flow to the pad bearings. As an alternative to the flow controllers capillary tubes or orifices may be used to control the flow. It is stated that in rolling glass, air may be used in the pressure pads.

Abstract: 1,133,560. Boots &c. J. S. KAMBORIAN. 4 Sept., 1967 [22 Sept., 1966], No. 40235/67. Heading A3B. A lasting machine of the type in which a shoe upper on a last, supported bottom down in the machine, is moved heightwise relative to a downwiping member includes means for selectively maintaining the downwiping member either in an inoperative position or in a working position during the heightwise movement of the shoe. As described the toe lasting machine of Specification 1,108,221 is modified by the addition of a drive bar 198 which is operated by an air motor 192 and which is connected to the rear mounting rod 184 of the downwiping member i.e. the yoke 176. The rod 184 can slide in a bracket 178 and when it is in its forward position the yoke 176 is positioned above the shoe upper to perform its downwiping action when the shoe is raised by its support (not shown). When the rod 184 is in its rearward position the yoke 176 clears the shoe upper when the shoe is raised. The control circuit includes a selector valve (not shown) which in its first position causes the yoke 176 to be moved forwardly under light pressure while the shoe is being raised to perform its downwiping operation, heavy pressure being exerted by the motor 192 when the shoe has reached its upper most position to clamp the shoe upper against the last. When the selector valve is in its second position the yoke 176 is held in its retracted position while the shoe is being raised and at the completion of this movement is clamped against the last under heavy pressure. This second operating procedure is used when lasting shoes of the mocassin-type having a ridge R on their uppers U which might catch on the yoke 176 during the downwiping operation.

Abstract: 1405755 Absorbent carbon pellets by pelletizing carbon black SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 30 Aug 1972 [1 Sept 1971] 40792/71 Heading C1A Carbon pellets of increased mechanical strength and suitable for use as an absorption agent are obtained from an aqueous suspension of soot, i.e. that originating as a by-product in the manufacture of synthesis or town gas by the partial combustion of hydrocarbons, by agitating this suspension in the presence of a hydrocarbon binder and a pellet reinforcing additive, separating the pellets formed by such agitation from the liquid phase, drying the pellets and heating the dried pellets at a temperature in the range 300‹ C. to 3000‹ C., the said hydrocarbon binder being volatile under the drying conditions whilst said pellet reinforcing additive is non-volatile in these conditions, but being capable at a temperature in the range 300‹ C. to 3000‹ C. to which the pellets are heated of melting or decomposing such that on cooling the so-heated pellets have a greater mechanical strength and substantially the same porosity as pellets formed in the absence of said additive or without the heating. The additive may be a bituminous material, which may be supplied as a solution, or as a dispersion of fine particles in the binder, and the particles formed are then heated at 350‹ C. to 800‹ C. in an atmosphere containing little or no oxygen. This atmosphere may contain or consist of steam. Alternatively the additive may be fibres or filaments, e.g. of organic polymer polystyrene, or nylon, when the dried pellets are heated at 300‹ C. to 400‹ C. In further alternatives, the additive is glass powder or is argillaceous material. With the argillaceous material, the dried pellets are heated at 1600 to 2000‹ C. The pellets are preferably heated in a fluidized bed. The pellets obtained may be used in sorption processes, e.g. for purifying water. Other fibrous additives suggested are cellulose, wool, metal wool, and glass wool.

Abstract: 1,271,949. Automatic voltage control. C.A.V. Ltd. Aug. 15, 1969 [Sept. 3, 1968], No.41823/68. Heading G3R. The voltage of a D.C. generator 11 (or an alternator-rectifier unit) is maintained at a predetermined value by a conventional transistor regulator comprising transistors TR1, TR2, TR3 and associated components, the regulator input 17a also being responsive to a limiting circuit comprising transistors TR4, TR5, TR6, Zener diode Z2 and associated resistors. This circuit produces an output signal when the generator output current reaches a predetermined value, the current being sensed by a resistor R18 to produce a voltage corresponding to the predetermined current, which voltage drives transistor TR4 out of saturation to turn on the transistor TR6, raise the potential at terminal 17a and so cause the regulator to limit the voltage of the generator. Resistor R12 provides a reference voltage for the limiting circuit whose magnitude is determined by the setting of variable resistors VR2, VR2A and the break-down voltage of the Zener diode Z2. The normal regulated voltage is determined by the setting of variable resistors VR1, VR1A and the connection of the terminal 13 to divider terminal H, M or L.
