Title: Improvements relating to foundry moulding apparatus
Inventor: HICKS FRANK
IPC: B22C11/00
Filed: 1957-10-04
Abstract: 860,717. Moulding-machines; foundry-plant. COLEMAN-WALLWORK CO. Ltd. Jan. 2, 1959 [Oct. 4, 1957], No. 31212/57. Class 83 (1). A mould turnover unit comprises a base, a mould-receiving table mounted at one end on a shaft supported in bearings at one end of the base, clamps on the table movable to grip the mould on opposite sides, means to turn the table about the axis of said shaft, fluid-pressure cylinder means for operation of said clamps and table-turning means, and valve means on said base and operated by the placing of the inverted mould upon said table for controlling the operation of said fluid-pressure cylincler means. The mould-receiving table 13 is secured to the shaft 12 and is rotatable therewith through rack-andpinion mechanism driven by a cylinder 39. The table carries clamping-arms 20 which secure a mould 22 to the table when actuated by a floating cylinder 24, whose piston-rod 25 is secured to one clamp, the cylinder itself being secured to the other clamp. Movement of the mould on to the table from the rollers 18 adjacent the moulding-machine actuates a valve 23 in the pneumatic circuit to cause the cylinder 24 to operate the clamps. Simultaneously the piston 39 is actuated to invert the mould to the position 22a, Fig. 2. At the end of the turnover movement, a stop 45 on the table actuates a valve 46, whereupon the clamps are released and the table is returned. In the position 22a, the mould is preferably received by rollers 55 on a transfer-table 53, Fig. 6, from whence it is pushed by a pusher 62, actuated by a cylinder 60, controlled, e.g. by a valve on the table 53 opened by deposition of the mould thereon, on to a conveyer for conveying the mould to pouring and other operating-stations. Alternatively, a cam 82 on the end of the shaft 12 may actuate a valve 83 in the pneumatic circuit of the pusher 62 to cause the pusher to operate shortly after the table starts its return to its initial position, ready to receive another mould. At the end of the ejection stroke, a valve 77 is operated by the pusher to restore the pusher to its initial position. The conveyer comprises pallets 85, Fig. 8, which receive the moulds ejected from the transfer-unit, and comprise cams 84 which actuate control-valves such as 86, 86a, for control of the turnover and transfer units, disposed on a frame 88 adjacent the turnover unit. In one arrangement, Fig. 8, a conveyer runs alongside two turnover units A and two transfer units B. In a further modification, each turnover unit and transfer unit receives and deals with two or more moulds at a time, e.g. two turnover tables may be mounted on respective shafts at opposite ends of the unit, and disposed side-byside or end-to-end with a transfer unit at each end of the turnover unit.

Filed: 1968-07-02
Abstract: 1282092 Parallel operation of generating plant MIRRLEES BLACKSTONE Ltd 23 July 1969 [2 July 1968] 31580/68 Heading H2H An electrical generating system comprising a plurality of individual generating plants is provided with means whereby the plants can be on-loaded or off-loaded to suit the requirements of the system total load and the load capacities of the individual generating plants. The system includes a memory store containing a plurality of memory units, one for each of the generating plants, each memory unit providing information of the load capacity of the associated plant and whether or not it is on-loaded to the system. Means are also provided to give a signal indicative of the total load on the system which signal initiates the operation of a device which scans the memory store to on-load certain of the generating plants until the total load demand is satisfied. Should the load demand increase, the increase in the total load signal will initiate a further scanning of the memory store which will cause the next available generating plant with sufficient load capacity to be on-loaded to cope with the increased demand. Should the load demand decrease one or more plants will be off-loaded in such a manner that overloading of the plants remaining on-load is avoided. The system is effective to substitute one generating plant of a load capacity comparable to another should failure of the latter occur. Arrangements are also provided to deal with the problem of a generating plant failing to start when required for on-loading. The onloading or off-loading of the plants may be effected in a sequential mode or an optimizing mask in accordance with the load capacities of the various plants.

Abstract: 532,018. Label making machine. BEZENCENET, M. Dec. 12, 1939, No. 32057. Convention date, April 12. [Class 73] [Also in Group VIII] Adhesive labels are made by applying a labelforming strip to a travelling band by means of a pressure sensitive adhesive and cutting through the strip to form the labels without cutting the band. The strip 12, Fig. 1, is coated with adhesive at 14 and meets the travelling band or support 20 which is of transparent material, coated with lacquer at 21, the two passing over a roller 18 and reversed, by known means, at 30 to bring the label strip uppermost. The support is perforated at 31 and the label strip cut by means of a die and anvil 41, 42. The united strips are then heated to soften the adhesive to allow the waste from the label strip to be separated and led to a roll 53 the labels and supporting strip being led to a second roll 55. In another form of apparatus, the label strip is applied to an endless metal band 200, Fig. 22, and cut into labels by dies 215, 216, the waste being led away at 228. The separated labels are then transferred to the supporting strip 236 which is led over an acute angled block 237 ; the supporting strip is then perforated at 242 and the strip with its attached labels led to a roll 246. Figs. 12 and 13 show one form of adhesive applying apparatus. The label strip is led round a roller 62 dipping into a bath 60. Stripes are wiped clear of adhesive and the thickness of the layer determined by means of an eccentrically mounted cylinder 80' having a number of concentric rings 80. The cylinder is adjusted angularly to vary the thickness of the adhesive, the rings wiping adhesive-free stripes. In a modification blade springs, in conjunction with a similar eccentric arrangement, are used to form the adhesive-free stripes. The disposition of the adhesive and label is such that the latter is left with a free edge and the perforations in the support are chosen so that a given length of support carrying a determined number of labels can be readily separated.

Title: Improvements in or relating to friction gears
IPC: F16H15/46
Filed: 1931-11-24
Abstract: 392,917. Variable-speed and other friction gearing. MANDLER, E., 13, Rue Washington, Paris. Nov. 24, 1931, No. 32567. Convention date, Nov. 24, 1930. [Classes 80 (i) and 80 (ii).] In variable-speed and other friction gearing of the interleaved type, one set 3 of flexible discs consists of smooth plates, while the other 4, or, if desired, both sets, carries a series of studs 5, which rotate and slide radially in slots in the discs or may lie with radial freedom in one or more continuous rings between concentric relatively movable parts of the main discs. As shown in Fig. 4, the studs may comprise metal centres 15, engaging radial slots 16 in the discs 14, and circular or polygonal outer pieces 17 of friction material and may be held laterally and radially in position by springs. A continuous ring of rollers 5, Fig. 9, may lie between the main disc 14 and a spring ring 20, rigid or flexible arms 22 on the disc engaging the studs at intervals. Speed ratio is varied, Fig. 1, by moving rollers 8, 9, applying axial pressure to the discs, between the shaft centres. Auxiliary plates 6 prevent escape of the studs. In a modification, a set of intermediate discs carries single rings only of studs which engage sets of flexible plates on the driving and driven shafts, change of gear ratio being effected by sliding the set of intermediate discs between the shafts. In a modification of this form, Fig. 15, the intermediate shaft 39 is permanently geared to the driven shaft 2, about the centre of which it swings to change the gear ratio, the necessary axial pressure being supplied by a spring 47 bearing on conical discs 48 carried on spherical bearings 49, 52 and interengaging with rollers 50. The axial pressure may be produced hydraulically, pneumatically, electromagnetically, or by springs or weights, either from without or from within the studs.
