Title: Means for indicating the Roll Pass Opening in a Rolling Mill or Calender
Inventor: STONE MORRIS DENOR
IPC: B21B37/64
Filed: 1966-08-16
Abstract: 1,190,738. Rolling. UNITED ENG. & FOUNDRY CO. 27 July, 1967 [16 Aug., 1966], No. 36664/66. Heading B3M. [Also in Division G3] A rolling mill or calender comprises a pair of work rolls 17 mounted in chocks 16 with piston- and-cylinder assemblies 18 between the chocks, means responsive to any displacement of the piston relative to the cylinder, caused by displacement of the chocks from a pre-set position, which produces a signal which activates means to restore the chocks to their initial separation. The mill or calender has back-up rolls 13 mounted in chocks 12 and urged together by a screw-down 20 and a piston-cylinder assembly 22 in each housing. Each piston-cylinder assembly 18 positioned between the chocks 16 comprises a piston 26 which bears against the upper chock and a cylinder 28 in a recess 27 in the lower chock. The piston 26 has an armature 34 which passes through a winding 33 mounted on the cylinder. The winding is connected by leads L1, L2 in series with the winding of the adjacent assembly in one arm of a Wheatstone bridge. The cylinder is supplied with fluid through a passage 31. The assemblies 18 urge the chocks 16 apart to the required roll separation and one of the arms of the Wheatstone bridge network is adjusted to balance the bridge. Any displacement of the work rolls, i.e. increase in work gauge, unbalances the bridge and a signal is recorded on a meter (42e), Fig. 2 (not shown). The signal is amplified and operates a servo valve (23) which controls fluid flow from a pump (P) to the assembly 22 to compensate for the displacement. An alternative form of assembly 18, Fig. 4 (not shown), comprises a plunger (38) of magnetic material which is displaceable in a coil (39) mounted in non-magnetic material (37), e.g. brass. The resistance of the coil depends on the position of the plunger relative thereto. The effective mill modulus of a mill incorporating the automatic control means above is 500 x 10<SP>6</SP> 1b. sq. inch compared with 25 x 10<SP>6</SP> 1b./sq. inch of a conventional mill.

Title: Improvements in or relating to furnace burner system
Inventor: BLOOM FREDERICK STUART
IPC: F23D17/00
Filed: 1957-11-25
Abstract: 828,502. Burners. BLOOM ENGINEERING CO. Inc. Nov. 25, 1957, No. 36670/57. Class 75(1) A burner comprises a body 15 extending at its front end through a refractory block forming part of a furnace wall 11 into a combustion recess 12 thereof to which combustion recess the air and fuel in gaseous or spray form pass by two sets of passages 25, 26 in the peripheral wall of the burner body the front end wall 21 forming a closure and the fuel and air respectively passing along the interior and exterior of an open-ended sleeve 30 the front end of which can be positioned so that only air passed to the rearmost set of passages 26 and only gaseous fuel to the foremost set of passages 25. The sleeve end can thus be set so that mixing of the fuel and combustion air does not occur till they are discharged from the burner end, or the sleeve end can be set slightly back to allow mixing of the air and gaseous fuel in the small space 22 below the passages or can be set a little further forward to allow air and gaseous fuel to enter the foremost passages 25 in a low proportion of air/gas, the complementary air for complete combustion entering by the rearmost passages 26. This prevents backfiring when a fast burning gas such as coke oven gas or hydrogen is used. For a sprayed fuel from a nozzle 35 shown disposed within the sleeve the latter is retracted so that its front end lies behind such nozzle 35 the mixing then being effected in the main space of the body 15. The sleeve is shown in Fig. 4 as flanged at the front end to slide on the interior wall of the body and will prevent mixing of the air and fuel until discharged into the recess 12 when the flange 41 is positioned between the two rows of passages 25<SP>1</SP>, 26<SP>1</SP>, Figs. 4 and 6, or will allow a variation of the air/fuel ratio when the flange 41 cuts across the front row of passages 25<SP>1</SP>. The front end of the burner body which is exposed to the high temperature may be a renewable one screwed on or welded, as shown in Fig. 9, at 64<SP>11</SP>, to the main burner body 60<SP>11</SP> and the end face 62<SP>11</SP> may have a refractory cover 98 cast thereon. The furnace wall 89 is in this form shown convex to the burner and the two sets of passages 80", 81<SP>11</SP> are arranged to converge their jets and cause the mixing air and gas to be directed parallel to the convex surface; no mixing of the air and gas occurs until the jets discharge from the passages since the sleeve engages a bore in an inward shoulder portion 91 of the burner body. Adjustment of the burner body to position its front end appropriately projecting into the furnace may be effected by inserting shims between the back plate 115, Fig. 10 (not shown), of the burner body and the outer wall plate 116 of the furnace.

Title: Method and apparatus for forming containers or the like from thermoplastic sheet material
IPC: B29C51/04
Filed: 1962-09-27
Abstract: 972,488. Blow moulding. HOFFCO S.A. Sept. 27, 1962 [Oct. 9, 1961], No. 36746/62. Heading B5A. In a plunger-assisted blow moulding process the sheet material is first mechanically deformed by the moving plunger and then applied around the plunger by introducing compressed gas into the die cavity. Gas at a higher pressure is then blown through the plunger so that during the final stages of the forward movement of the plunger the sheet is suspended between two cushions of gas, the gas in the die cavity being released and the sheet transferred to the mould wall when the plunger has reached the end of its forward stroke. A sheet F, e.g. of polyethylene, polystyrene &c., is heated at 7 and advanced between a plunger carrier 11 and a die carrier 12, each die cavity 10 of carrier 12 comprising four wall sections 30 normally biased away from each other. Die carrier 12 is then forwarded so that ends 32 of members 30 abut a plate 56, thus causing the members to slide along surfaces 38, 39 in the die carrier 12 to a closed abutting position defining the die cavity. The carrier is further forwarded until the sheet is clamped between plate 56 and a gate 6, the carrier 11 having been forwarded in the meantime so that plungers 9 deform the sheet and enter the die cavities 10 to perform the blow moulding in the above described manner. During the moulding the sheet is clamped between a spring washer 23 carried by the plunger and the ends 32 of die wall sections 30, the material being severed by circular blade 22. The compressed gas supply to the plungers and the die is then discontinued, the carriers withdrawn to allow the die cavity to re-expand, the finished article ejected by an air blast through duct 50, a new heated section of sheet F advanced, and the cycle repeated.
Patent GB-368349-A (GB)
Abstract: 368,349. Time switches ; partly electromagnetic switches. McELDOWNEY, W. P., 50A, Collingbourne Road, Shepherd's Bush, London. Dec. 4, 1930, Nos. 36613/30, 1320/31, and 13550/31. [Class 38 (v).] A device specially adapted for switching on the lights of a vehicle at a predetermined time comprises a clockwork switch which at the predetermined time closes a circuit to an electromagnet the armature of which then closes the lighting circuit and is held latched until released later by hand. The movement of the armature may also break the energizing circuit of the electromagnet and the manual device for releasing the latch may simultaneously open other contacts in the energizing circuit. The clockwork switch may comprise as shown a contact arm m on the hour-hand spindle which arm makes momentary contact at the predetermined time with a contact k mounted on a disc f fixed to an indicator disc 71 having teeth 79 engaging a spur wheel 78 on a spindle 76 so that the contact k may be rotated to any desired angular position by means of a knob 75 on the spindle 76. In a modification, Figs. 1, 2 and 3 (not shown), the disc carrying the contact k is rotated by means of a friction disc engaging its periphery. The electromagnetic switch may comprise as shown a coil 7, an armature 10 flexibly pivoted at 13 to a bracket 12 and carrying a contact 41 adapted to bridge two contact strips 40 in the lighting circuit. The top of the armature also engages a step 14 in an arm 15 pivoted at 11a, the arm 15 falling down when the armature is attracted and holding it in place and also breaking the energizing circuit of the electromagnet at contacts 17, 18. To break the lighting circuit the handle 75 which thus serves a dual purpose, is pressed in, thereby rotating a lever 20 about its pivot 21 and causing an arm 45 of the lever to raise the catch 15 so that the armature 10 may move to the open position. The movement of the lever also opens contacts 23, 24 in the energizing circuit of the electromagnet, so that the handle 75 must be pulled out again to prepare this circuit when it is next desired to put the timing device into operation. In modifications, Figs. 1, 2, 3 and 4 (not shown), the handle 75 operates through Bowden wire mechanism, and may be separate from the handle which serves to rotate the contact k of the clockwork switch for setting purposes.
