Title: Apparatus for the continuous manufacture of copper anodes for electrolytic refining
IPC: C25C1/12
Filed: 1973-01-10
Abstract: 1388069 Making anodes for electrolytic refining ONAHAMA SEIREN KK 10 Jan 1973 [10 Jan 1972] 1431/73 Heading B3A [Also in Division C7] Apparatus for the manufacture of copper anodes for electrolytic refining comprises, means for storing copper strip 7, Fig. 4, in a loop, means 11 for intermittently advancing the strip and simultaneously straightening it, a blanking press 12, Fig. 5, for cutting a plurality of anode plates 4 each with a pair of side lugs 5 from the strip, a pusher 15 to move the plates on to diverging conveyer means 16, 16a which pass the plates through a cooling chamber 18, means for rejecting defective anodes, means for receiving and stacking the accepted anodes, Fig. 8, and pallet means 26 for receiving and transferring the stacked anodes away from the apparatus. The strip 7 is received from continuous casting apparatus and passes through pinch rolls 6 on to a pair of pivotable tables 8. The tables pivot downwardly by the weight of the strip acting against a balancer 9. A feed leveller 11 passes a pre-determined length of strip into the blanking press 12 and it is controlled by signals passed from a detector 10 and the press. Dies (13), (14), Fig. 6 (not shown), cut the strip into a pair of oppositely shaped anodes 4, Fig. 5, and correct any deformation caused during blanking. The pusher 15 moves the anodes to pinch rollers 17 and then on to the conveyers 16, 16a, each of which leads to a sorting conveyer, Fig. 8. The anode abuts a stop 20, is examined for defects and if it is to be rejected, rollers 21 are raised and it is moved at right angles to the normal feed direction, Fig. 7 (not shown). The stop 20 is lowered to allow satisfactory anodes to pass on to rollers 24, which are pivotable to allow the anode to drop on to a stand 25. The stand is lowered as each anode falls on to it and when it is level with the pallet 26, a pusher 27 transfers the stack of anodes on to the pallet.

Title: Improvements in suction-operated drum filters
IPC: B01D33/067
Filed: 1928-01-17
Abstract: 283,876. Vernay, J. B. Jan. 18, 1927, [Convention date]. Rotary filters.-Suction drums of the type comprising sectors, which are separately connected to a distributor valve on the shaft so that each sector can communicate successively with suction means and with a source of compressed air, are built up of wooden or other elements 1 with grooves 5 on their outer surface over which the filter cloth is placed. The elements are separated in groups by blocks 8 and held together by semi-circular bolts 2. The grooves of each element drain into a cross channel 6, the cross channels being arranged to form in each group a single channel in communication by means of a radial pipe 7 with the distributing valve. With this construction the space beneath the filter cloth, and consequently the amount of liquid discharged with the solid matter under the influence of the compressed air, is a minimum. Spaced bars may be used to form channels taking the place of the grooves. The Specification as open to inspection under Sect. 91 (3) (a) states that the grooves may be arranged in a fan-shape outward from the ends of the pipes 7. This subject-matter does not appear in the Specification as accepted.

Filed: 1924-01-21
Abstract: 210,084. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Hanson, I. S.). Jan. 20, 1923, [Convention date]. Regulating.-The steam from the high-pressure turbine stage 11 is directed to either the lowpressure stage 12 or the conduit 23 of the bleeder system or to both by means of a valve 24 controlled by gear responsive to the steam-pressure in the bleeder system and to, extreme positions of the turbine speed governor 18. The spindle of the butterfly valve 24 carries a pinion 31 in mesh with a rack 32 on the piston-rod 33 of a servomotor. Movement of the piston is determined primarily from a diaphragm in a pressureresponsive device 37, the movement of which is communicated to a valve 36 by way of a hunting- gear 41, 35, 51. The rod 41 moves between projections 54, 55 on a rod 56 connected to the speed governor 18 so that when the speed is excessive or the turbine is being shut down the valve 24 will be moved appropriately. The high-pressure stage 11 is preferably an impulse stage and the used steam is led round to a chamber 19 on the nozzle side, en route for the box 20 containing the valve 24. In the form shown in Fig. 7, the high-pressure stage is inverted and the steam passes without reversal to the valve-box.
