Title: Improvements in dynamo electric machinery
IPC: H02K1/20
Filed: 1929-05-17
Abstract: 333,616. Lancashire Dynamo & Motor Co., Ltd., and Howard, J. W. May 17, 1929. Armatures and field magnets, cooling and ventilating.-The core of a dynamo-electric machine is provided with plates of metal of good thermal conductivity interleaved between groups of the core plates, and extending beyond them into longitudinal passages through which cooling air flows, the edge portions of the cooling plates being slotted to form teeth which are bent or twisted. The bent portions may make contact with the walls of longitudinal ducts through which air flows. In the form shown, wherein the invention is applied to a stator, the cooling plates A, in the shape of annular discs or segments, which may be of copper, are placed between groups of laminµ B, Fig. 3, and extend into the air ducts c<1>, Fig. 6. Fins a<1> are formed by notching the parts of the cooling plates which extend beyond the core, and these fins are bent either at right-angles to the plane of the cooling plate, or they may in any other way be inclined thereto. Alternatively, they may be bent down in contact with the core laminee as at a<6>, Fig. 5, and make good thermal contact with the inner peripheries of copper cooling ducts D, Fig. 6. If this arrangement is adopted, a flange a<6>, Fig. 6, may be provided on the cooling plates instead of separate narrow fins. The cooling air passes through the ducts D, which may be fitted with longitudinal heat-transmitting plates d<1>. For cooling a rotor, the fins are formed on the inner periphery, and project into air passages formed inside the rotor laminµ. The cooling plates may be so modified as to provide radial ventilating passages in the core.

Title: Process for the production of improved products from polymers of vinyl esters of saturated carboxylic acids
IPC: C08K5/00
Filed: 1945-06-20
Abstract: Organic solvent soluble polymers of vinyl esters of saturated carboxylic acids, or copolymers or heteropolymers thereof with a minor proportion of a substituted ethylene, are insolubilised by blending with at least 1 per cent of a compound capable of generating free radicals on heating, selected from N-chloro derivatives of organic amides and amines, amine oxides, acyl and dialkyl peroxides and metal alkyls and their salts, the blending being carried out below the temperature at which the compound is active and heating the blend at a temperature at which the compound is capable of liberating free radicals.  The compounds may be added to the polymer by mixing on rolls, by dissolving the components in a suitable solvent or by mixing aqueous dispersions. Specified polymers, copolymers and heteropolymers include polyvinyl chloroacetate, propionate, laurate, stearate, benzoate, the copolymers of vinyl acetate, propionate and butyrate with vinyl chloride, vinylidene chloride, tetrafluoroethylene 1 - chloro - 1 - fluoro - ethylene and vinylidene fluoride; polymeric maleic esters, acrylic and methacrylic esters, itaconic and fumaric esters.  Listed insolubilising agents are benzoyl, lauroyl, acetylbenzoyl, urea, diethyl and methylethyl peroxides, chloramine-T, phenyl copper, tetraethyl lead, lead diethyldibromide, zine diethyl and trimethylamine oxide.  Up to 25 per cent by weight of the polymer of insolubilising agent may be used and generally the process is carried out at temperatures below 200 DEG  C., preferably in the range of 100-150 DEG  C.  Fillers, pigments and dyes may also be added to the compositions.

A batch of toilet paper 11 is conveyed by a pusher 16 of chain conveyer 17 to station 15. At station 15 a plurality of the batches is pushed rightwards by respective pushers 19 over on to plate 21, slots 27 and 28 being provided for the passage of pushers 19 to ensure that the bottommost sheet is included in the batch. Each batch is thus deposited'on a support 29 and is pressed thereon from above by a spring impelled pad 31. Each pad and its corresponding support 29 is screw threaded upon respective parallel shafts 34 and 42 so that they form nuts adapted to be conveyed by the respective screws. The screws formed on shafts 34 and 42 are of diminishing diameter so that as the shafts are driven the screws thereon are displaced by differing amounts so that the batches are separated one from another.  Thereafter each batch is displaced to the right by a pusher 66 which is operated by cam 76 (Fig. 1, not shown), roller 77 and arm 78. In order that each pusher 66 upon its return journey shall not contact an approaching batch each pusher is elevated as it returns by the operation of cam 83 which moves downwards against roller 96 to pivot the pusher upwards. To effect this movement cam 83 is carried by member 94 which is operated via arm 93 by cam 89 and follower roller 91. Each batch 11 is then conveyed into the waiting pockets 97 of a conveyer 98 by a rack 99 which moves with a cyclic movement.

Patent GB-657771-A (GB)
Title: Improvements in or relating to pneumatic gauging apparatus
IPC: G01B13/18
Filed: 1948-06-14
Abstract: 657,771. Fluid-pressure gauging-apparatus. STEVENS, A. H. (Sheffield Corporation). June 14, 1948, No. 15948. [Class 106 (ii)] A gauge for checking the alignment of the bores of a con-rod 11 to ensure that the axes are parallel, comprises a table 10 with the plug members 12, 13 protruding above the surface on to which the con-rod is placed for the gauging operation. Each of the members 12, 13 is provided with air nozzles arranged in pairs axially offset and transversely opposed, each pair forming sets in which the members of a set are connected to a common indicating means giving the cumulative effect of the various members of a set. -The action of the pairs of nozzles may be seen from a consideration of Fig. 5 where the effect of a slight anti-clockwise rotation of the big end axis is to allow more air to escape from nozzles 30 and 31 and less from nozzles 28, 29, thus unbalancing the system previously balanced with a master con-rod in position on the gauging members 12, 13. Fig. 6 shows the arrangement of pairs of nozzles in the two members 12, 13, and their connections to the indicating means 36, 41, 54, 58. Thus, all the nozzles 28 to 33 are arranged in a common geometric plane containing the axes of the members 12, 13, the nozzles 28, 29, 32, 33 forming a set co-operatively associated with a common flow gauge 36 which may be of the type described in Specification 548,568. Nozzles 30, 31, 34, 35, constitute a second group associated with a flow tube 41. The flow tubes are arranged adjacent to one another in a common housing 60, so that a non-parallel condition of the axes of the bores in the con-rod may be readily observed from the different levels of the indicators in adjacent flow tubes, since the level of all the indicators is first adjusted by means of the master con-rod. For gauging parts having bosses the arrangement may be reversed by providing cylindrical holes in the table 10 in which the nozzles are arranged and into which the part to be gauged is fitted. A modification is shown in Fig. 7 intended for gauging the axis of the bore in a workpiece with respect to a surface thereof, comprises a handle 66 through which an air supply line 64 passes, a boss 71 containing a pair of nozzles 68, 69, co-operating in the manner described and a face 70 accurately machined normal to the axis of the boss 71. The gauge is inserted in the bore of the workpiece so that the surface 70 abuts on to the face of the workpiece and the workpiece or the gauge is then slowly rotated. If the axis of the bore is at right angles to the face no change will occur in the level of the float in the indicator flow tube, misalignment of the axis of the bore with respect to the face being indicated by a change in level of the float, as the gauge or workpiece is rotated. Specification 543,806 also is referred to.
