Filed: 1965-02-18
Abstract: 1,062,297. Countercurrent flow ion exchange process. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 17, 1966 [Feb. 18, 1965], No. 7088/65. Heading B1J. An ion exchange stage comprises a resincontaining vessel 1, main liquid inlet means 6, product liquid outlet means 9 provided with resin retention means, bypass outlet 10, bypass inlet 11 and liquid overflow outlet 12 having resin retention means 13. In operation, the upward flow of liquid from inlet 6 forms an inverted packed bed 20. Lower region 19 then contains a settling mass of resin in liquid. A flow of liquid and resin is introduced through bypass inlet 11 and the resin settles on to the packed bed. Periodically the flow through inlet 6 is reduced, for example by means of a time switch controlling variable speed pump 7, and the resin falls towards the bottom of vessel 1. A multiple stage apparatus providing a closed cycle for resin flow (Fig. 2, not shown) comprises 3 water-softening stages (100), (200), (300) and 3 resin regeneration stages (400), (500), (600). Flow control means may be provided, for example in stages (300), (600) to ensure a net upward flow of liquid. In the apparatus of Fig. 1, flow control valve 14 is responsive to variations in the pressure differential measured by pitot head 15. In the apparatus of Fig. 3 (not shown), the product liquid outlet pipe (8) passes vertically through the top of the vessel and has a right-angle bend which is above the right angle bend in the liquid overflow pipe (12). The difference in height of the overflow points determines the extent of the net upward flow of liquid.

Openers, cleaners, &c.-Compound eccentrics, the throw of which can be varied by relative rotation of the inner and outer eccentrics while the machine is in operation, are used to impart vibration to pulp strainers of the rotary drum or other type or to paper or rag-dust screening apparatus or to other machines employed in the - manufacture of paper. The inner member a' of the eccentric is formed in one with a hollow shaft a. Spiral slots e, e<1>, Fig. 5, are formed in the inner member a<1> and in the outer member d of the eccentric, and a radial stud, carried by a rod b which extends through the shaft a, projects through the inner slot e into the outer slot e<1>.

Title: Reproduction circuit arrangment for a three colour line sequential colour television signal
IPC: G11B20/02
Filed: 1973-02-14
Abstract: 1372822 Colour television TED BILDPLATTEN AG AEG-TELEFUNKEN TELDEC 14 Feb 1973 [15 Feb 1972] 7243/73 Heading H4F A colour television signal derived from a recorder 13 includes a luminance signal Y M  to which has been added, in a low frequency portion, line sequential colour difference signals R-Y M , G-Y M , B-Y M . The low frequency portion of the signal is separated by a low-pass filter 14 and fed to two one-line delay lines 15 and a switching circuit 16 to provide continuous R, G, B signals, which are used in a matrix 17 to produce R-Y and B-Y signals. The R, G, B signals from switching circuit 16 are also fed to an adder 23 to produce a luminance signal Y M  which is added at 22 to a signal passed from filter 14 via an inverting amplifier 21, the resulting signal being added at 20 to the output signal from recorder 13 passed via a compensating delay 19, thus effectively subtracting the line sequential colour difference signals from the output signal from recorder 13, to provide luminance signal Y M  at output 24. In an alternative embodiment (Fig. 6, not shown) the part of the signal separated by lowpass filter 14 is passed to a modulator (30) before being passed to delay lines 15 and adder 22, the output of adder 22 being demodulated before being passed to adder 20. In this case adder 22 may receive the signal from filter 14 directly together with the arithmetic mean of the signals delayed by one and two lines duration by delay lines 15 (Fig. 7, not shown). A switch which is opened during reception of a monochrome signal, may be included at the input to filter 14 (Fig. 6, not shown), the synchronizing pulses being removed by clipping before the modulator, or two switches may be included, at the outputs of adder 22 and matrix 17, each switch being opened during the vertical blanking periods, and for reception of a monochrome signal (Fig. 7, not shown). Matrix 17 may provide a modulated PAL or NTSC chrominance signal. The signal derived from recorder 13 may alternatively include luminance signal Y to which has been added in the low frequency portion line sequential signals of the form R-Y x , G-Y X , B-Y X , Y x  being a luminance signal derived from any combination of R, G, B, sequential signals of the form -(R-Y x ), -(G-Y x ), -(B-Y x ) being added at 20 to the derived signal.

Title: Improvements in or relating to space heating elements
IPC: H05B3/26
Filed: 1958-03-06
Abstract: 925,183. Coating with metals. SPACE HEATING Ltd., and P. EISLER. March 3, 1959 [March 6, 1958], No. 7263/58. Class 82. [Also in Group XI] A " printed-circuit " type of space-heating element comprises an electrically conductive ribbon attached by a spraying process to an insulating backing ribbon. The conductive material (aluminium or lead or a semi-conductor) is sprayed on to a wide sheet, e.g. resin-impregnated paper, in a multipass spraying machine and the sheet is then slit into a number of ribbons. As shown, the sheet passes between rollers 10, 27 over a cooled plate 16 facing an adjustable spray gun 18. Resistance measuring contacts 14, 24 enable the resistance to be measured after each pass so that the speed and number of subsequent passes can be selected to give the desired resistance. The transverse resistance can be similarly measured to test the uniformity of the spray. The coating may be pressed by rollers after certain passes and different materials (e.g. graphite) may be sprayed at certain passes. Excess of coating material may be removed by abrasion. Specification 823,435 is referred to.

Abstract: 453,358. Electromagnetic switches and automatic circuit - breakers. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, and MILLS, J. A. W., 43, Cedar Crescent, Low Fell, Co. Durham. March 9, 1935, No. 7401. [Class 38 (v)] In an electric relay of the kind in whch the relay contacts are operated after a definite time interval by a weighted member which is released on energization of the relay electromagnet, the movement of the weighted member being retarded by an eddy-current brake whose metal disc is driven by the weighted member, the metal brake disc is mounted vertically and approximately at right angles to the front of the relay casing and is located between the relay electromagnet and the relay contact structure. As shown in Figs. 2 and 4, the movable relay contacts G<1> are attached to a weighted sector F which is arranged in falling to drive an eddy-current braking disc K<2> through gearing and a one-way clutch constituted by a pawl and ratchet J, J<4>. The sector is normally held in the raised position by an arm E<2> engaging a roller F<1> attached to the sector, the arm E<2> being secured to a shaft E<1> passing through a vertical supporting plate B<1> of the relay casing, the shaft E<1> carrying at the other side of the plate B<1> an arm E which is attached by a link D<4> to an arm D3 acted upon by a spring D<5>. The arm D<3> carries an armature D<2> of an electromagnet D, D<1> which when energized releases the weighted sector. The fall of the sector is delayed by the braking action of the disc acted upon by the magnet M and the contacts G<1> engage and bridge fixed contacts H in the controlled circuit, as the sector reaches its lowermost position. The time of operation may be varied by a screw N, a nut H<2> on which carries a lateral projection N<3> engaging the arm E and also a depending guiding projection N<5> which by moving in a graduated slot C2 indicates the time lag chosen. The scale C<2> is observed through a window A<2> in the front of the relay casing A<1>. The sector F carries an arm F<5> adapted to trip a latch R allowing a drop indicator P, P<1> to move behind an aperture C<3>. The indicator is relatched manually by a knob S<1>. The relay is restored to the normal position shown when the electromagnet D, D<1> ceases to be energized. A knob O is provided to permit optional manual actuation of the relay, the lever O<1> engaging the end O<2> of the lever D3.
