Title: Improvements in or relating to electric plug and socket couplings
Inventor: HUBBOLD SYDNEY
IPC: H01R13/527
Filed: 1955-11-15
Abstract: 806,118. Two-part couplings. GENERAL ELECTRIC CO. Ltd. Nov. 8, 1956 [Nov. 15, 1955], No. 32685/55. Class 38 (1). A plug and socket connector has a plug comprising a barrel-shaped body 25 from which projects in one direction a cable entry portion 30 and in the other direction a D-shaped portion 26 carrying a D-shaped, insulating contact support 12 having annular grooves 17 in which are located stud contacts 23, 24. The body portion 26 has an annular groove 32 which co-operates with a rod 6 located transversely of the socket entry aperture 4 in which the body 25 is adapted to make a flame-proof seal. The rod 6 limits the angular position in which the plug may be inserted as shown in Fig. 2, but subsequent rotation of the plug through 180 degrees to engage the plug and socket contacts causes the rod to engage in the groove 32 to prevent withdrawal of the plug without first disengaging the contacts. The socket contacts comprise helical springs 9 supported by insulating plates 7 at opposite ends of the rectangular socket casing 1 and against which the stud contacts press. In the example shown the springs 9 engage terminals 10, 11 of a lamp fitting for use in a coal mine and the casing 1 has a further aperture 4 for a second plug, the contacts of which are also adapted to engage the springs 9 which thus connect the two plugs together. This second plug may either be connected to a further similar plug for supplying another lamp fitting, whereby a chain of fittings may be built up, or it may simply have its centre contact bridged to one of two earth contacts 15, 31 on the plug. The centre contact of the supply plug is connected to a pilot conductor so that until the final bridging plug is in position, the pilot circuit is not complete and a contactor in the supply circuit cannot be closed. The pilot contact 23 on each plug is smaller than the supply circuit contacts 24 so that removal of a plug breaks the pilot circuit and hence the supply circuit before the contacts 24 disengage from their springs 9.

Title: Ink feeding device for printing machines
IPC: B41F31/02
Filed: 1933-11-24
Abstract: 434,107. Printing-machines. SCHNELLPRESSENFABRIK KOENIG & BAUER AKT.-GES., and HORN, L., 4, Friedrich- Koenigstrasse, W³rzburg, Bavaria, Germany. Nov. 24, 1933, Nos. 32955 and 32956. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 25, 1934]. [Class 100 (ii)] Inking - mechanism.-Ink is applied to the distributing-cylinder 12, Fig. 1, through narrow orifices in a bar 9 arranged between the cylinder and a series of large nozzles in a casing 6 which is supplied with excess ink by a single pump. In one form, Fig. 2, the bar is of porous material such as felt. The ink is drawn from a reservoir 4, Fig. 1, by a pump 1 and forced through pipe 5 to a chamber 7, Fig. 2, in the casing 6, the chamber 7 communicating with the back of the bar 9 by a series of large nozzles 8 each provided with a screw valve 19 for adjusting or cutting off the supply. Excess ink returns to the reservoir through a pipe 17 containing a pressure regulating valve 18 and a pressure meter 32. The casing 6 is carried by arms 20 free upon a shaft 21 and is pressed towards the cylinder 12 by adjustable springs 29 carried by arms 23 fixed to the shaft 21 and bearing against lugs 22 on the arms 20. The shaft 21 may be turned by worm gear 24, 26 to move the bar 9 clear of the cylinder when desired and to return it to its initial position determined by the engagement of an arm 27 on the shaft with an adjustable stop 28. In a modification, Figs. 3 and 4, the bar 33 is made of bronze, vulcanized fibre, indiarubber or other hard material provided with slots or perforations 34 for the passage of the ink. These perforations are arranged close to the edge of the bar which is first engaged by the cylinder 12 as it rotates, the unperforated portion of the bar serving to distribute the ink. To provide for a uniform flow of ink through all the perforations, the back of the bar 33 is formed with a separate chamber 36 for each nozzle 8, the length of the perforations decreasing with increasing distance from the nozzle as shown, or their cross section increasing with their distance from the nozzle.

Title: Improvements in or relating to carrier wave magnifying systems
IPC: H04N11/14
Filed: 1953-11-27
Abstract: 759,386. Television. PHILCO CORPORATION. Nov. 27, 1953 [Nov. 29, 1952], No. 32985/53. Class 40 (3). [Also in Group XL (c)] A carrier, e.g. a colour television subcarrier, which comprises the vector sum of separate amplitude modulated components of different phase representing different intelligence, has its components converted to a different relative phase and/or amplitude, without demodulating the carrier components, so that a standard carrier transmission may be adapted to a receiver requiring a different relative phase or magnitude of the components. To this end, to the original components OA, OB (Fig. 2), e.g. in quadrature phase relation, components OA<SP>1</SP>, OB<SP>1</SP> of reversed phase difference, respectively equal to the same fraction of OA, OB are added, and this fraction and the phase displacement relative to OA, OB are made adjustable to give vector sum components OA<SP>11</SP>, OB<SP>11</SP> of selectable amplitude and phase. This may be effected, Fig. 1, by heterodyning the modulated composite carrier, whose components have a frequency fc, with auxiliary signals of fixed frequencies # 1  and (# 1 +2#c) and deriving from the common mixer 11, or from separate mixers, sum and difference frequencies of equal frequency (# 1 +#c) selected by a filter 16 or by filters, if the mixersare separate, the outputs being then vectorially added. As shown, the relative amplitude and phase of the outputs are adjusted by a phase shifter 15 and attenuator 14. The frequencies # 1 , (# 1 +2#c) may be the sum and difference frequencies of an oscillator of frequency (f 1 +fc) used in maintaining synchronism between the video colour signals and the phosphor elements of a television cathode-ray tube, and of a colour synchronizing frequency fc, the frequencies fc, (f 1 +fc) being applied to the grids and cathodes of a pair of triode mixer tubes, one triode having its cathode load variable to control the amplitude of one output at frequency f 1  + 2fc, and a phase adjuster corresponding to 15 (Fig. 1), in its anode circuit. The frequencies f 1 , (f 1 +2fc) filtered out are then applied to the same grid of a third mixer tube to another grid of which the composite modulated carrier (frequency fc) is also applied, and the final output frequency (f 1 +fc) then derived from a bandpass filter. The system may be applied in a television receiver for altering the received signal components to a different relative phase suitable for the spacing, e.g. equal spacing of the phosphor elements on a colour cathode-ray tube, or to altering the relative amplitude of the colour components, e.g. when one having smaller maximum variations has been boosted in amplitude before transmission to improve the noise-free performance. Specification 753,451 is referred to.

Title: Centrifugal apparatus for the uninterrupted purifying of paper pulp
IPC: B04C5/18
Filed: 1938-07-08
Abstract: 516,815. Centrifugal separators. BERGES, A. July 8, 1938, No. 32988/39. Divided out of 516,806, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 11, 1939. [Class 23] A vortex separator, for the continuous purifying of paper pulp, has a sheltered space in the lower part of the stationary container 1, the sheltered space being separated from the vortex chamber in the upper part of the container by a baffle plate 4 which permits communication only by an annular space 5 of small radial depth round its periphery. An outlet pipe 6 connects the sheltered space to the outlet 7 so that a current is maintained through the space 5 from the vortex chamber to the sheltered space. The casing consists of two opposed conical parts with a cylindrical part between them, and it has an inlet 2 of rectangular cross section for the pulp. The heavy impurities are thrown to the wall and pass through the annular space 5, while the pulp and light impurities pass upwards inside the inner casing 3. The impurities pass inside the flared pipe 18 to the outlet 20, and the pure pulp passes through the annular outlet 21 to the pipe 22. The heavy impurities pass down the sheltered space to the sluice valve 9, and any light impurities that may have passed through the gap 5 flow with the fluid current behind the plate 8, which obstructs the entrance to the pipe 6, through the pipe to the outlet 7. Where a more effective separation of the lighter constituents is desired the apparatus is divided into two separate parts. The first part separates the heavy impurities but does not include the flared pipe 18 and the outlet 20. These parts are arranged in a second separator in which the light impurities are separated from the pulp. Specification 516,806 is referred to.
