Abstract: 1004580 Belt or chain tensioning devices; friction gearing P HAMMELMANN 27 Dec 1962 [16 Jan 1962] 48667/62 Headings F1A and A1B7 In a belt, chain or friction drive between a pump or compressor 2 and a motor 6, a piston device 1 supplied with fluid pressure tapped from the pump output acts on the motor support 5 to regulate the belt tension, or the frictional contact, in accordance with the pump load. As shown the motor support 5 comprises a tiltable platform which is biased clockwise by the device 1 to tension a belt or chain drive 8. In a modification wherein the belt drive 8 is replaced by a friction drive, Fig. 2 (not shown), the device 1 is positioned to bias the support 5 anticlockwise. In further modifications the motor support 5 is slidable towards and away from the pump 9 under the action of the device 1. The piston device 1 comprises a piston 10, Fig. 5 movable in a cylinder 12 by pressure fluid from a throttle 20 adjacent an inlet 18. A partspherical cup 11 on the piston 10 engages a corresponding seat in a fixed base 4, while the cylinder 12 has screws or other means for connections to the support 5. A spring 15 acts between the piston and cylinder to provide an initial tensioning force.

A permanent mould for use in casting metal is made of a material sintered from finely divided metallic and oxide-ceramic components of high melting point such as finely dispersed Mo and/or Wo and an oxide-ceramic consisting of finely dispersed zirconia and containing stabilising additions of calcium or magnesium oxide. Moulds of this material are made by intimately mixing the finely divided metallic and oxide-ceramic components, pressing the mixed material to a desired mould shape, and subsequently sintering the material. The formed mould may be machined to final dimensions and in the case of large moulds for example, as used in centrifugal casting the mould may be constructed in parts which are subsequently screwed together.

Title: Process for separating aromatic hydrocarbons

Filed: 1971-11-03
Abstract: 1343652 Separating aromatic hydrocarbons MITSUBISHI GAS-CHEMICAL CO Inc 3 Nov 1971 [5 Nov 1970] 51151/71 Heading C5E Aromatic hydrocarbons are separated from admixture with non-aromatic hydrocarbons by contacting the mixture with a complex solution consisting of HF, BF 3  and m-xylene and/or at least one polymethylbenzene having at least 9 C atoms, and separating a hydrocarbon phase rich in non-aromatics and lean in aromatics, and an acid phase comprising the extractant mixture plus aromatics. Counter-current contact may be carried out at 30‹ to- 20‹ C. and 0À5-5 kg./cm.<SP>2</SP> G. using a complex solution in which the molar ratio of BF 3  : HF is 0À05 to 0À20 : 1 and that of hydrocarbon : BF 3  is 0À6 to 0À9 : 1. The extract solution may be back-extracted with a solvent, e.g. a saturated hydrocarbon, from which the required aromatic may be recovered by distillation, or may be thermally decomposed to remove HF and BF 3  and form a hydrocarbon mixture from which the aromatic is distilled. The process may be combined with separation of m-xylene from a xylene mixture. Thus (Fig. 2) HF/BF 3  from 6 extracts m-xylene in column 1 from feed 5 using diluent (hexane) from 7, and the resulting HF-BF 3 -m-xylene complex solution 9 extracts aromatics from raw hydrocarbon feed 10 in column 2. The dissolved aromatics 12 are removed from the complex solution in stripper 3 by solvent 13, a distillable aromatic/solvent mixture being removed at 14. The m-xylene complex solution is thermally decomposed at 4 to provide m-xylene at 16 and HF/BF 3  for recycle through 6. Alternatively, the aromatic-loaded complex solution is fed direct from 2 to 4, in which case a distillable mixture of hydrocarbons is formed at 16. In a further embodiment of a combined process, the complex solution is formed by (1) extracting an aromatic hydrocarbon mixture containing mxylene and/or at least one polymethylbenzene having at least 9 C atoms, with HF, BF 3  and a diluent. A portion of this complex solution is used to separate aromatics from a hydrocarbon feed, and the resulting extract is used as raw aromatic hydrocarbon mixture in step (1). The remaining portion of the complex solution is thermally decomposed. Examples describe the separation of benzene, toluene, and xylenes from aromatic/non-aromatic hydrocarbon mixtures.

Title: Devices for regulating the thickness of rolled products

Filed: 1970-10-29
Abstract: 1319327 Rolling mills CREUSOT-LOIRE 29 Oct 1970 [31 Oct 1969] 51466/70 Heading B3M The thickness of a workpiece being rolled in a rolling mill is maintained constant by controlling the pressure existing in an hydraulic screwdown 2, the pressure being measured by a detector 7 and controlled by movement of a plunger 5 into the cylinder of the screwdown, using a follow-up system. The plunger is moved in response to an error signal derived by a comparison of the position of the plunger (measured at 8) and the pressure (provided by the detector 7), the signal at 8 being automatically varied if the error signal departs from a predetermined, but adjustable, range. Changes in the measured pressure are assumed to be due to out-of-roundness of the mill rolls, which out-of-roundness is thereby automatically compensated for. Additionally, an error signal e 3  for controlling the movement of the plunger may be modified to take account of the workpiece thickness measured before or after the mill, bending of the mill rolls, or play in the oil film bearings of the mill. The position of the plunger 5 is controlled by a servo valve 4 in response to any difference between a reference signal e 3  and the actual position of the plunger as measured by a sensor 8. An error signal caused by bending of the mill rolls may be added at 12 if desired. Variations in the thickness of the workpiece cause the signal e 3  to move outside a given range, and for this reason a threshold device 17 and integrator 18 are provided to modify the signal so that it stays in the range. A signal em fed to the threshold device is derived from a circuit which takes into account variations in the ingoing or outgoing workpiece thicknesses. Signals relating to these thicknesses and also relating to the bearing oil-film correction, are fed to respective terminals 24-26.

Title: Adding constituents to molten metals
Inventor: COATES RODERICK BOMFORD
IPC: C21C1/10
Filed: 1964-12-17
Abstract: A constituent is introduced into molten metal, particularly between 0.02 and 0.1% of pure Mg into cast iron, by loading a predetermined solid charge of the constituent into a passage leading through an opening in the shell of a container e.g. ladle or furnace of the molten metal at a level below that of the metal surface and operating means to propel the charge at a controlled rate through the opening into the metal.  The means preferably comprises a rammer attached to a hydraulic piston and cylinder. The charge may be a magnesium rod with two plugs comprising asbestos washers and graphite blocks, located in front and behind the charge, the rear plug being located in the position formerly occupied by the front plug when the charge is completely introduced into the container.  Following magnesium treatment, the molten metal may be similarly inoculated with Fe-Si alloy to promote the desired spheroidal graphite structure.

[Also in Division G3] A fluid bearing has a constant clearance maintained by means controlling the flow of fluid to opposite zones 7, 8 of the clearance, the means comprising a pressure-sensitive element 21, 22 separating a first chamber 26 connected to the clearance, and a second chamber 33, the element 21, 22 controlling a valve 36 itself controlling the flow to the zones 7, 8. In Fig. 3 gas enters the chambers from passage 23 and orifices 24, 31, and exits from chamber 26 by outlets 28, 29 and from chamber 33 by outlet 35. Movement of shaft 2 towards outlet 28 increases the pressure in chamber 26 and depresses slide 21 in diaphragm 22 and also valve 36.
