Filed: 1972-05-26
Abstract: 1396153 Pressing out moisture IMPROVED MACHINERY Inc 26 May 1972 [22 June 1971] 24987/72 Heading F4G [Also in Division B1] Liquid is removed from suspensions such as pulp and effluent sludge by forcing it through a plurality of pipes 20 (Fig. 4) and vat 10 between two porous rolls 40, 42 which are rotated in opposite directions about parallel axes, the hubs 56 of roll 40 being mounted on slidable blocks 62 (Fig. 3) and the hubs of roll 42 being mounted on fixed blocks 64. The liquid is pressed through the circumferential walls of the rolls, and the filtrate drains through conduits 58 at each end of the rolls. The pressed solid material is removed from the rolls by doctor blades 46, 48, and discharged from conduit 24 by rotary screw 26. Tubes 70, which are filled with pressurized air from source 74, exert constant biasing forces through blocks 62 on the ends of roll 40 to hold the latter spaced away from roll 42 by nip 44. Blocks 62 are connected by tie rods 66 to a pair of platens 68 and link (lever) systems 82, 84, each comprising four links, the links 86 (Fig. 5) of the two systems being rigidly connected by a rod 166, and the arrangement being such that, when the device is actuated by the action of compressed air from tank 138 on pistons 128 in cylinders 126, the rolls 40 and 42 are urged towards one another but the axes of the rolls are maintained parallel. In the event of the passage of foreign (tramp) material longitudinally offcentre through nip 44, the movement of the end of roll 40 most adjacent to the tramp material away from roll 42 automatically causes commensurate movement of the links of system 82 or 84 which immediately actuates the rod 166 to provide identical movement of the other system. If extremely large tramp material enters the nip 44, the switch 160 (Fig. 3) is tripped by the third link 98 whereby solenoid-operated valve 152 is shifted by spring 156 to exhaust air from the tank 138 through conduit 142 so that roll 40 moves away from roll 42 and substantial damage is prevented.
Patent GB-954420-A (GB)
Title: Method of and apparatus for stretching thermoplastic films
IPC: B29C55/16
Filed: 1962-06-29
Abstract: 954,420. Stretching films. ASAHI KASEI KOGYO KABUSHIKI KAISHA. June 29, 1962 [June 30, 1961], No. 25053/62. Heading B5B. Apparatus for stretching flat thermoplastic film of substantially uniform thickness throughout comprises a pair of circuitous guide means between sets of feed and take-up rolls. The guide means comprise endless rails for guiding two sets of clips adapted to grip opposite edges of the film, and include driven wheels adjacent feed and take up rolls for delivering clips to and removing clips from the film. The clips in each set are interconnected so that the spacing between adjacent clips, while variable, cannot increase beyond a predetermined amount. Means for heating the film during stretching may be provided. In one embodiment (Fig. 1) a film B is fed from rolls f, longitudinally stretched by passing to take-up rolls g rotating at higher peripheral speed, and simultaneously transversely stretched by guide means A, A 1  carrying sets of clips J, J 1 . Each set of clips in eludes a series of clip elements a connected by folding links b. Wheel c opens the clips and delivers them to the film, wheel d opens and removes the clips from the film and wheel e is provided with pawls for folding the clip linkage. Each clip body 1 (Fig. 2) carries a pin 4 which in turn carries links 6 and a bearing 5 on which the clip moves along guide rail 7. The film is gripped by finger 2 and holding spring 3. Wheel c includes a sprocket-wheel 8 (Fig. 3) having recesses for receiving pins 4 and moving them forward and a disc 9 adapted to constrain gripping finger 2 so as to provide a film-receiving space. Wheel d is of similar construction. Wheel e includes a disc 12 (Fig. 5) having pawls 13 pivoted thereto and springs 14 anchored at one end to disc 12 and secured at the other to pawls 13. Each spring holds its associated pawl outwards so that it engages with clip pins 4. In operation, clips a are carried by sprocket-wheel 8 to a point where, with fingers opened by disc 9, they can grip the unstretched film B. As the guide rails are straight beyond the film gripping point, the clips are then disengaged from the sprocketwheel, and the fingers 2 are released from disc 9 so as to grip the film. As the film is advanced, the clips in each series are carried forward by the film and become increasingly spaced apart in accordance with the longitudinal stretching. At the point where the film is completely stretched by a predetermined amount the interconnecting clip linkages are fully extended, and thereafter, the clips are pulled forward by the wheel d. As the clips reach the removal point, clip pins 4 engage a sprocket-wheel 10 and the clips are opened by disc 11. The clips are returned to their starting position under the pull of wheel e, which pulls the clips forward and folds the links. As the clips reach wheel c, the clip pins 4 are again engaged by sprocket-wheel 9 and carried to the film gripping point.

Title: Improvements in or relating to steel shot for use in blast cleaning, peening, polishing and the like
IPC: C22C33/02
Filed: 1953-09-14
Abstract: Steel shot is made by melting iron or steel in a furnace and maintaining it in an oxidized state throughout the heat, boiling the molten bath to remove gases and metallic oxide inclusions, keeping the silicon content below 0,10 per cent until the final silicon alloying, de-oxidizing and alloying the bath to 1,15 to 1,40 per cent carbon, 1,00 to 1,50 per cent manganese, 0,40 to 0,90 per cent silicon, 0 to 5 per cent chromium, 0 to 0,4 per cent vanadium, 0 to 2,5 per cent nickel and 0 to 1,0 per cent copper, the remainder being iron and the usual impurities, pouring the metal, disintegrating it into particles, initially quenching the particles in a mild quench medium and then heat-treating the particles to produce a tempered martensite micro-structure.  The preferred method of performing the invention is as follows: steel scrap with a low sulphur and phosphorus content is melted in a high temperature, e.g. electric arc, furnace and then ore (iron oxide) is added in an amount approximately 1 per cent by weight of the total charge.  The silicon and manganese contents are reduced respectively to below 0,10 per cent and 0,20 per cent and the bath then boils, after which the slag composition is controlled by the addition, in the case of basic furnaces, of ferro-manganese, mill scale, burned lime or fluorspar, and in the case of acid furnaces, ferromanganese, mill-scale, silica-sand or lime.  At the pouring temperature additions are made to alloy and deoxidize the bath; ferrosilicon and ferro-manganese are added as well as a strong deoxidizing agent such as calcium-silicon-manganese, aluminium, titanium or vanadium.  The molten metal is preferably disintegrated as described in Specification 638,826, but may also be performed by other methods such as directing a solid stream of water from a nozzle against the falling stream of metal, and the disintegrated steel particles are caught in a bath of water, preferably at 120 DEG  to 160 DEG F., which serves to initially quench the shot.  The entire disintegrating apparatus may be surrounded by an inert gas such as nitrogen.  The shot is given the tempered martensite micro-structure by heating at 1650 DEG  to 1750 DEG F. in a rotary retort-type furnace fed with raw natural gas or other carburizing type gas, quenching in warm water or other mild quench medium such as oil or a soluble oil-water mixture and finally tempering at 900 DEG  to 1050 DEG F.

Gear-wheels, grinding and trueing teeth of.- The pitch and shape of a gear wheel are corrected by mutual grinding with a crown wheel in successively varying positions of engagement, relative reciprocating motion being given to the two wheels and a torque applied to bring the tooth faces into contact. The wheel A is secured to a carrier J supported on a rod F, which is carried by a ball and socket joint L on a reciprocating head E. A crown wheel B, the teeth of which are a counterpart of those of the wheel A surrounds the wheel A and is secured to the base D of the machine. Torque is applied to the wheel A by springs 0 engaging brackets N on the carrier and compressed by nuts Q acting on a bracket P secured to the head E. The wheel is reciprocated, abrasive material preferably being employed to expedite grinding. After grinding in this manner, the angular position of engagement is altered, grinding then again taking place and these operations are repeated. The opposite faces of the teeth are then similarly ground by applying a torque in the opposite sense. In grinding helical teeth, the carrier is provided with a circular track around which passes a cord or cords, which then pass over pulleys to a counterweight. This allows of rotation of the wheel as it is reciprocated.
