Title: Improvements in the manufacture of electric capacitors
Inventor: SHEN TZU EN
IPC: H01G13/00
Filed: 1953-08-24
Abstract: 759,614. Capacitors. BRITISH DIELECTRIC RESEARCH, Ltd. Aug. 24, 1954 [Aug. 24, 1953], No. 23328/53. Class 37. [Also in Group VIII] A method of manufacturing capacitors comprises forming a composite strip consisting of one or more dielectric strips to which conductive layers, in the form of either separate metal foils or metallized coatings are applied, folding the strip transversely to a zig-zag form and then dividing the strip by transverse cuts into short lengths to form individual capacitors. The conductive layers are divided by narrow transverse bands into short lengths, and the cutting operation is performed at the regions of these bands. In the arrangement shown, polystyrene strips 1, 2 are led from rolls 3, 4 and are combined with metal-foil strips 7, 8 respectively at the slotted rollers 5, 6, the two pairs of strips being brought together by their passage between the rollers 11, 12. The composite strip is drawn forward intermittently and during the instants when it is stationary, knifeblades 30 descend to cut the metal foil strips 7, 8, transversely, thus dividing the metal layers into a number of short lengths 32, 33, 34, 35, as shown in Fig. 2. The rollers 11 (see also Fig. 2) and 12 are provided with alternate V-shaped ribs and grooves whereby the strip issuing therefrom is scored longitudinally. By the action of a series of rollers 38, 39, 40, 41 the composite strip is folded transversely to a zig-zag form as it proceeds. Polystyrene layers 15, 16 are applied to the zig-zag folded strip 42 as it passes between the rollers 13, 14. The strip 42 then passes into an enclosure 18 (see also Fig. 3) containing intermittently-driven rollers 19, 20 and, operated in synchronism therewith, heated sealing bars 43, 44 which are periodically brought together to seal the folds of the dielectric together at the regions of the gaps in the metal foils, pressure-plates 45, 46 which are periodically brought together to bring slots 49, 50 into register with each other whereby metal terminals can be sprayed on to the edges of the strip, and knife blades 51, 52 which move together when the strip is stationary to cut through it at the region of a gap in the metal foil. Terminal wires may be subsequently attached to the metallized parts of the cut-off capacitors. The arrangement described may be modified to manufacture capacitors having electrodes applied by a metallizing process. In such an arrangement the apparatus to the left of rollers 11 and 12 is replaced by apparatus, similar to that described in Specification 759,613, for removing narrow transverse bands of metallizing from a metallized dielectric strip. The metallizing may also be removed longitudinally at the inner surfaces of each fold of the zig-zag folded strip 42. It is stated that the dielectric used may be paper impregnated or coated with polystyrene. Specification 723,841 also is referred to.

Title: Improvements in and relating to the machining of piston rings to a predetermined shape
Filed: 1951-10-08
Abstract: 723,224. Turning piston rings; copy-turning. ISLER, F. Oct. 8, 1951 [Oct. 27, 1950], No. 23337/51. Class 83(3). In a method of producing a master piston ring from which copying- cams for use in turning piston rings in a lathe can be made, a ring having overlapping ends and means for adjusting the overlap and fixing the ends in position, is first adjusted so that the ends have a certain overlap, is then machined to a truly concentric shape, and finally has its ends adjusted to a lesser overlap and fixed in such position. In a first method, a pre-turned ring 2, 3, Figs. 2, has tongued and grooved ends secured together with full overlap in an unstressed condition by a pin 4. The ring is machined in this condition to be accurately cylindrical and concentric. The pin 4 is next removed and the ring is stretched open so that the ends overlap just sufficient for the insertion of a further pin 4a, Fig. 4, and in this stressed condition the ring is clamped between end plates 10, 13, Fig. 8, in a lathe spindle 11 to serve as a templet for turning a copying cam. In a second method a pre-turned ring has portions milled away to form a tongued and grooved joint, Fig. 6, the ring is next closed up and pinned through a hole 8b in a stressed condition and then turned to be truly concentric. Finally, the ring is released and allowed to take up its original unstressed condition where it is pinned and used as above as a templet for producing the cam. Specification 692,906 is referred to.
