Apparatus for feeding annular rim blanks to a working position in a rolling mill comprises a carrier movable to and from the working position, work clamping means on the carrier and means for releasing the clamp when the carrier has moved to the working position. A rim rolling machine comprises a base frame 11, a lower roll 14 and its driving shaft 13 mounted directly on the frame and an upper roll 15 and its shaft 16 mounted on a frame 18 hinged at 19 to the base frame and adapted to be swung upwardly by an hydraulic cylinder assembly 20 to permit the placing of a blank over the lower roll. Slidably mounted on rods 28 extending parallel to the roll axes is a plate-like carrier 27 movable by a double-acting cylinder 36. Mounted on the carrier is the rim clamping mechanism comprising at one end a fixed abutment block 55 and roller 54 and at the other end a movable section 56 operable by a cylinder 66 and carrying an arcuate abutment block 76 and a lower roller 79. Rim blanks are delivered to the carrier by a trough-shaped shoot 85 and an elevator 86 which is traversed on vertical guide rods 92 by a cylinder 93<SP>1</SP>. As a rim blank rolls from the shoot on to a supporting plate 89 of the elevator, it actuates a switch to admit air to the lower end of the cylinder 93<SP>1</SP> and so raise the elevator to its upper position where another switch is actuated to move forward the slide section 56 of the clamp. Initially the roller 79 engages the blank and raises it to a position where it is clamped between the abutments 55 and 76 directly in line with the roll 14. The elevator is .then allowed to descend and air is admitted to the cylinder 36 to move the carrier so that the blank extends over the roll 14 and another switch is actuated to lower the hinged frame 18. As this frame descends a switch is operated to open the clamp and so deposit the rim on to the roll 14. As the frame rises after the rolling operation the clamp is again closed to lift the rim from the lower roll. The carrier then returns to its normal position and the clamp is opened to release the rolled blank on to a discharge shoot 116.

Title: Improvements in or relating to filtering apparatus
Inventor: BRAMWELL FREDERICK WILLIAM
Filed: 1950-08-03
Abstract: 721,531. Gravity sand filters. TURN-OVER FILTER CO., Ltd. July 27, 1951. [Aug. 3, 1950] No. 19388/50. Class 46. [Also in Group XXIX] Filtering apparatus of the type in which the sand is washed by ejection from the bed through tubes by jets of water 'issuing from nozzles, the sand being carried up the tubes in a state of turmoil and then settling back on the bed incorporates at least one nozzle comprising pressure-actuable valve means in the nozzle adapted to be opened by the pressure of the wash water to allow issue of the jet, and to close automatically to prevent ingress of sand as soon as the pressure of the wash water falls below a predetermined amount, as for example when it is turned off. Wash water entering a nozzle casing 1 at 3, Fig. 1, depresses an annular flexible diaphragm 5 which in turn causes a hollow valve member 4 to which it is secured at the centre to move downwards to the position shown in this Figure. Wash water thus ejected. from the nozzle outlet 2 .passes up an openended tube 10, Fig. 3, mounted above the nozzle, and entrains sand from the filter bed to effect its circulation and hence cleaning. A number of nozzles, for example five, arranged on a circle may be simultaneously supplied with wash water by radial pipes 12 emanating from a central filtrate discharge pipe 13, the filtrate apertures 15 of which are temporarily obturated by a sleeve 16, which may be actuated by the mechanism 17 ... 20 or hydraulically, to permit either filtered or unfiltered water to be passed up the pipe 13 and sleeve 16. Where more than one nozzle is provided the spring-loading of each valve may be varied by an adjusting screw 7, Fig. 1, to ensure simultaneous operation of the nozzles and hence uniform distribution of wash water. A small balancing port 8 is provided in the wall 4 of the valve-member, Fig. 1, to connect both sides of the diaphragm 5 both to prevent opening of the valve by other than a steady and substantial pressure (of wash water) and to ensure that when the pressure is reduced by shutting off the flow of wash water a spring 6 is enabled to close the valve quickly and promptly. Operation of the nozzles may take place after or simultaneously with a backflushing operation (without sand circulation) brought about by manipulation of suitable valves. The nozzle casings 1 may alternatively be arranged horizontally or at any desired angle.
