Patent GB-603721-A (GB)
Title: Improvements in and relating to the insulation of transformer end coils
IPC: H01F41/12
Filed: 1945-08-17
Abstract: 603,721. Transformers. MICAFIL, Ltd. Aug. 17, 1945, No. 21082. Convention date, Aug. 31, 1944. [Class 38 (ii)] In a method of insulating the end coils or end-coil groups of a liquid-immersed transformer with a cylindrical winding, the outermost end coil is first bound with a tape-like binding of insulating material and then superposed on the next or second coil and the two bound together in a similar manner, these being next superposed on the third coil and all three bound together, this process being repeated until the required number " n " of end coils are thus bound, thereby forming a graduated insulation which increases towards the end of the winding, after which the insulating coverings are cut along their circumferences in a plane perpendicular to the axis of the coils and bent upwardly to form a screen. Fig. 1 shows an arrangement wherein a core 17, surrounded by a cylindrical insulating sleeve 8 has applied to it a coil 1 associated with a protective metal ring 16 in a binding 9, these bound members being placed on the coil 2 and covered by an annular wooden former 18 to receive an enclosing binding 10. In a similar manner these members are associated with the coil 3 and annular wooden former 19 in a binding 11, and then associated with coil 4 and former 20 in a binding 12. The bindings 9-12 are then cut successively along the lower outer edges of the associated coils, commencing with the binding 12, and bent outwardly, as shown in Fig. 2, the wooden formers 20, 19, 18 being removed in succession and replaced by blocks 15, 14, and 13. The binding 9 around coil 1 may be cut open or left closed, as shown. The flanges 10-12 formed by the upturned insulation may be secured together either completely or at intervals by an adhesive, or they may be baked together with the aid of a polymerisible material. The cutting and bending may be done either before or after the end coils are fitted on the insulating cylinder. The arrangement may be employed for concentric sets of coils which are separated by cylindrical insulating screens, and in one example, Fig. 4 (not shown), a high-voltage winding consisting of two groups of coils is located between inner and outer low-voltage windings. The insulating material for the coils may consist of paper, presspahn, fibre layers soaked in synthetic materials, or foil made of thermoplastic material.

Filed: 1965-05-21
Abstract: 1,059,015. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 21, 1965 [May 26, 1964], No. 21754/65. Heading H4R. A vocoder analyser periodically produces a set of digital signals representative of characteristics, e.g. the aggregate function, of the input signal which are inserted into a store, each set of signals produced is compared with the previous set stored in the storage device and only transmitted if there is more than a predetermined difference between the two sets of signals. In the Figure a speech signal is applied over lead 1 to the spectrum analysing filters 21-2n, rectifiers 31-3n and low-pass filters 41-4n. The outputs of the low pass filters are sampled periodically by gates 51-5n, operated over lines 61-6n from the analyser control apparatus, and the samples fed via analogue to digital converters 71-7n into a storage register 8 as a set of digital signals defining the aggregate function of the speech signal. After each sample has been taken, comparison circuit 10 is actuated by a signal on line 12 to compare the digital signals in register 8 with a previous set of digital signals stored in register 9. If the signals differ by more than a predetermined amount, e.g. differences of more than two units in the numbers stored in respect of more than two channels, then a signal is transmitted via a decision circuit 11 to initiate the transfer either in serial or parallel form of the contents of register 8 to the output line 13 and also to replace the contents of register 9 by the contents of register 8 ready for further comparisons. If there is no substantial difference revealed by the comparison then the contents of register 8 are discarded, register 9 is undisturbed and a signal is transmitted via circuit 11 to indicate at the receiver that the previously transmitted aggregate function signal is to be re-used.
