Abstract: 824,929. Electrodialysis. PERMUTIT CO. Ltd. June 21, 1956 [July 5, 1955], No. 19420/55. Class 41. An electrodialysis cell comprises a number of narrow compartments bounded on their opposite major faces by ion-permeable membranes 2, 4 of which at least every alternate membrane is ion-selective, the membranes being separated around their peripheries by flexible spacers 6, rigid spacers 10 being inserted in the cell at intervals to replace spacers 6, the spacers 10 being held in position by rods 12 passing through their peripheries. The membranes are alternately cation-selective 2 and anion-selective 4 and the spacers 6 may be integral peripheral projections on the membranes 2, 4, as described in Specification 758,650, or may be separate members having an aperture in the centre to form a chamber and suitable holes and passages for leading liquid to and from the chamber, and may be of plasticized polyvinyl chloride (PVC), or rubber. The spacers 10 may be unplasticized PVC, ebonite, or metal with an insulating coating. The spacers 10 may be placed at regular intervals, e.g. every twentieth spacer, or at irregular intervals, and alternate spacers 6 may be different thicknesses, e.g. 1.3 mm. and 3.3 mm., the spacers 10 then being 3.3 mm. thick. In a modification, the rods 12 pass through the periperies of the membranes 2, 4 and the spacers 6, 10, e.g. through lugs or tongues projecting from the edges thereof.

Abstract: 1,201,681. Filling containers; endless conveyers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 14 April, 1969 [24 April, 1968], No. 19428/68. Headings B8A and B8C. Apparatus for filling containers e.g. bags, of the kind wherein a first container is presented to filling means substantially directly above the centre-line of a horizontal conveyer and, when filled, is caused or permitted to fall on to said horizontal conveyer, is further provided with an additional filling means off-set with respect to the centre-line of the conveyer and with a springboard or the like located beneath said additional filling means and adapted to deflect filled containers dropping thereon from the additional filling means on to the conveyer. In the arrangement shown a common hopper 2 (Fig. 1, not shown) feeds filling spouts 1 (not shown) and 6, spout 1 being located directly over conveyer 3 so that a bag 4 filled therefrom, drops directly on to the conveyer and the spout 6 being located downstream from the spout 1 and off-set from the centre line of conveyer 3 so that bag 7 thereon is not interfered with by bag 4 moving past. Beneath spout 6 is a spring- loaded pivoted board 8 arrang d so that when a filled bag 7 drops thereon it guides the bag on to the conveyer 3. Conveyer or supports 5 may be provided to prevent the bags toppling over. The apparatus is arranged so that bags 7 from spout 6 are fed on to the conveyer between bags 4 from spout 1 and are conveyed to bag closing means. Suitable bag clamping and weighing mechanism may be associated with each filling spout.

The cathode-ray tube of Specification. 985,438, in which a voltage applied to the deflection plates results in the deflection of the electron beam by a certain angle the beam being deflected over the electrode which consists of spaced elements having two different secondary emission factors so that a train of pulses arises at the output of the cathode-ray tube, is used to measure continuous quantities by applying to the deflection plates a voltage equal to the the difference of the absolute values of a voltage representing the quantity to be measured and an auxiliary sawtooth voltage of opposite polarity, the number of pulses emitted as the beam is deflected being counted to give the value of the voltage. In the embodiment described a series of measurements are effected, their average value being displayed in a counter. The input voltage Ux is applied together with the sawtooth waveform U 1  to a differential amplifier 7, the output of which is applied to the deflection plates 3 of the cathode-ray tube. When the sawtooth waveform U 1  is at zero the electron beam 2 is rapidly deflected to impinge on the electrode element 4 at a position which is determined by the actual value of the voltage Ux. As the sawtooth waveform U 1  decreases to its maximum negative value the electron beam is deflected so that a pulse train, the number of pulses in which represents the voltage Ux, is applied via a gate 10 to a counter 11. Under the control of a generator 9 the gate 10 may be opened for a multiple of ten measurements, the counter 11 dividing the total count by the number of measurements made.

Title: Automatic winding mechanism for timepieces
IPC: G04B5/24
Filed: 1955-07-11
Abstract: 774,846. Clocks and watches. REYMOND, P. E. July 11, 1955 [July 10, 1954], No. 19993/55. Class 139. Automatic winding mechanism for a timepiece comprises a differential gear the sun wheels of which are geared to the barrel and barrel arbor respectively and the planet gear of which controls a toggle mechanism which effects disengagement of the winding mechanism when the mainspring is fully wound and re-engagement of the winding mechanism after a partial unwinding of the mainspring. A pawl 5, Fig. 2, oscillated through an eccentric 10, a rod 9 and a Bowden cable leading from a revolution counter steps-on the barrel ratchet 4 reverse rotation of which is prevented by a detent 13. A gear 14, Fig. 3, on the barrel arbor 3 drives through a gear 15 one sun wheel 16 of a differential gear the other sun wheel 17 of which meshes with a gear 18 fixed to the barrel 1. The planet gear 19 of the differential is carried by a shaft 20 the upper end of which carries an arm 21 which moves between two pins 24, 24a, Fig. 2, on a yoke 22 pivoted on an arbor 23. The yoke 22 has two projections 25, 25a which co-operate with a pin 26 on a second yoke 27 the forked end 28, 28a of which embraces a pin 30 on the winding pawl 5. A toggle spring 31 is fixed at 33 to the yoke 22 and at 32 to the frame. The arrangement is such that during winding of the mainspring the arm 21 engages the pin 24 to move the yoke 22 counter-clockwise until, when the spring, is fully wound, the toggle spring 31 suddenly assumes its other stable position and the projection 25a meets the pin 26 to move the yoke 27 counter-clockwise so that the inclined surface 29 engages the pin 30 and moves the pawl 5 away from the ratchet 4. As the mainspring unwinds the arm 21 moves clockwise to engage the pin 24a and move the yoke 22 clockwise until the toggle spring 31 and the yoke 27 assume their initial positions and the pawl 5 re-engages the ratchet 4. The pawl 5 may be controlled by an oscillating weight.

An original is introduced manually or otherwise over a table 2 to the rollers 5, 5<SP>1</SP>, which are driven by a constant-speed motor until the leading edge of the sheet engages the switch 7, when the roller drive is disengaged and the rollers stopped by an electromagnetic brake, with the sheet in a predetermined rest position. A copy sheet 3 is separated from a pile and fed by the rollers 6, 6<SP>1</SP>, the rollers 6, 6<SP>1</SP>, 10 being driven by the same motor as the rollers 5, 5<SP>1</SP> until the leading edge of the sheet engages the switch 8, when the roller drive is disengaged and the rollers 6, 6<SP>1</SP> stopped by an electromagnetic brake with the sheet in a predetermined rest position. The switch 8 is adjustable in feed direction. The original is introduced after a copy sheet is in position. The switch 7 also acts on a delayed-action relay which releases both brakes and engages the rollers 5, 5<SP>1</SP>, 6, 6<SP>1</SP> with a second motor which drives the rollers 9, 9<SP>1</SP> at the copying speed of the machine so as to introduce the two sheets to the rollers 9, 9<SP>1</SP> in registered relationship.

In a clutch wherein torque is transmitted through a fluid containing magnetic particles in a magnetic field in a gap A between an input drum 18 and an output member 30, assisted, during slip only, by electrodynamic eddycurrent action of alternating poles 38, 40 on the output member 30, the magnetic fluid is constantly circulated through the drum from inlets 60, 65 to peripheral outlets 67 and/or fixed outer casing 16 for cooling. Sealing at the shaft is effected by inner permanent-magnet seals 70, each consisting of opposed U-shaped members, and outer carbon-block seals 68, the space therebetween being supplied continuously from an inlet 76, with clear water which passes through the magnetic seals 70 into the drum and prevents outward flow of iron particles.
