Abstract: 1,033,491. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 19, 1962 [Aug. 17, 1961], No. 29667/61. Heading H4K. In an exchange system in which metering pulses are stored in ferrite storage elements pertaining to the different subscribers of the system and in which the elements are successively scanned in order that the stored pulses may be transferred to the addresses of the subscribers located in a magnetic drum, each element is provided with an input, an output, a bias and a scanning winding and the arrangement is such that the output winding can only deliver an output pulse if a metering (input) pulse and a scanning pulse of a particular magnitude and shape are present in the respective windings at the same time. The elements which have a " square " hysteresis loop are normally biased into one state of magnetization and the presence of a metering pulse tends to drive them into the opposite state. When a scanning pulse is applied, the element " moves " into said opposite state during an initial part of the scanning pulse and reverts back to said one state during the final part of the pulse, this double change of state producing an output pulse which is detected by a bi-stable circuit. As described, the elements are arranged in a matrix FCM consisting of five 20 x 10 arrays and each array is associated with a magnetic drum MD. The drums are provided with two metering tracks MRT1 and MRT2, each track corresponding to 100 subscribers and a control track CRT. Each address in CRT comprises a 16-bit store and the addresses in MRT1 and MRT2 comprise 32-bit stores. Each element is scanned once every 25 msecs. (the drum rotates at 2400 r.p.m.) and since a metering pulse can last for a time of between 150 and 400 msecs. then between 6 and 16 (" metering ") pulses may be received in a 5-bit counter of CRT during one metering pulse. In addition, metering pulses are separated in time by at least 75 msecs. so that if during three successive scanning sequences no further " metering " pulses are recorded in CRT and if the number of pulses stored in the 5-bit store at this time is between 9 and 19 (6 " metering " pulses and 3 " absences ") then the number of metering pulses already stored in the relevant address of the metering track MRT1 or MRT2 is increased by unity. The minimum number 9 of pulses required before any entry is made in MRT1 or MRT2 ensures that spurious pulses in the metering winding of an element do not cause the false registration of a metering pulse. Reception of more than the maximum number 19 of pulses initiates an alarm. Reference has been directed by the Comptroller to Specification 841,949.

Abstract: 1,238,210. Selective printing; printing surfaces. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Oct., 1968 [24 Oct., 1967], No. 49008/68. Headings B6C and B6F. In a selective printer, characters are serially formed on a continuously moving endless carrier band 11 at a stationary station 13, and are transferred electrostatically or magnetically across an air gap from the band 11 to a copy sheet 18 moving continuously and at right angles to the direction of movement of the band. The characters are formed on the band in one of a number of ways. In (Fig. 2) a row of fluid expulsion nozzles (14) deposit discrete ink droplets (15) on to the moving transfer band 11, in response to electrical pulse commands. The ink droplets are held to the surface of the band 11 by capillary adhesive force which is overcome when printing is desired by the electrostatic field force of transfer station 19 (Fig. 2A). In an alternative embodiment, Fig. 4, a roller band conditioner 21 applies a non-wettable material 25 to fill empty impressions 26 in the coating on the band 11<SP>1</SP>. An impression maker 22 creates new impressions 27 in the non- wettable material 25 in response to pulse commands, so that an ink-coated roller 23 fills the empty impressions 27 with ink droplets 24. The impression maker 22 comprises a row of air jet nozzles as shown, or a row of needle point electrodes which form electrical arcs to rupture the non-wettable coating 25 and form the desired depressions 27. Alternatively, a row of fluid expulsion nozzles may deposit a negative of the image to be formed of non-wettable fluid upon a previously cleaned band surface. The negative so formed need not remain in liquid form, but could be solidified upon deposit on the band so that the ultimate cleaning is accomplished by reheating to effect removal. In Fig. 4, the ink is magnetic, comprising a suspended solution of iron particles in a coloured solvent. The band 11<SP>1</SP> is a permanent magnet with north and south poles 29 located on opposite sides of the band. The deposited droplets are held to the band magnetically until such time as the electrostatic or magnetic field transfer station 19 exerts an attractive force on the ink droplets to transfer them rapidly to the copy paper surface. As an alternative, if after depositing the droplets on the band, they are passed through an electrical corona discharge station or the band is maintained at a constant electrical voltage, a static charge, opposite in sign to the field used for printing is produced, which enhances the transfer of the droplets to the copy paper 18. The transfer band may be of non-magnetic material if a permanent magnet is located adjacent the band surface opposite to the surface on which the droplets are deposited. In an alternative embodiment (Fig. 5) similar to Fig. 4, the ink droplets are retained in the depressions (32), 27, solely by capillary action. In an alternative embodiment (Fig. 6), a row of electromagnets (34) create selectively magnetized areas (33) on a magnetizable band, which areas retain droplets of magnetic ink (40) applied by a roller (38).

A device for testing bulk tobacco or cigarettes 22 is similar to that described in the parent Specification but the reduction in volume of the tobacco chamber formed by the diaphragm 16 due to an increase in pressure in the chamber 1 causes air to be driven out of the tobacco chamber and to bubble out in a bath 20. The chamber 1 is connected to a pressure meter 9 and a compressed air source 5 via a three way valve 6. As the pressure in the chamber 1 is increased the air surrounding the cigarette is forced into a calibrated tube 18 and bubbles through the bath 20, the level of water in the bath being maintained constant by a reservoir 25. A further increase in the pressure in the chamber 1 causes compression of the cigarette and bubbles again pass through the bath, the pressure at which these bubbles start to appear being recorded. A photo-electric device and a counter records the number of bubbles as the pressure is raised to a final value. The reduction in volume of the cigarette is calculated from the product of the number of bubbles and the volume of a bubble as determined by a suitable calibration of the tube 18. By turning the valve 6 so that the chamber 1 is vertical to the atmosphere through passages 6c, 6e, the cigarette partially returns to its original volume drawing air from the tube 18. The amount that the water rises up the tube gives the change in volume of the cigarette. In a modification the meter 9 is replaced by a moving chart pen recorder, the pen receiving an impulse from the photo-electric cell whenever a bubble is released.

Abstract: 1,259,521. Papermaking. KIMBERLYCLARK CORP. 2 Jan., 1969, No. 338/69. Headings D2A and D2B. An absorbent tissue paper sheet, which may be creped, consists of a blend of fibres of two different kinds, uniformly mixed together. The fibres of one kind have little bonding capacity for one another and contain a water-insoluble, polyfunctional, polymerizable agent, which has a latent capacity for cross-linking cellulose and is developable to stiffen the fibres. The other fibres contain no cross-linking agent, have an inherent bonding capacity for each other and are bonded to each other at points of contact but these bonds are weakened by the presence of the first fibres, the bond between first and second fibres being weaker than that between the second fibres. The sheet may be made by (a) impregnating cellulosic fibres with an aqueous catalysed solution of the cross-linking agent, (b) ageing the impregnated fibres while wet with the solution to advance the agent to a water-insoluble stage, while retaining a cross-linking capacity, (c) blending the impregnated fibres with cellulosic fibres not so impregnated, to form a papermaking stock, and (d) forming a paper web by sheeting the stock and drying it under conditions to only partially cure the agent. The web may be creped either wet or dry, and may be subsequently heated to cure the cross-linking agent, eliminate the latent cross-linking capacity, and set the crepe. The cross-linking agent may be an N-methylol-urea or an N- methylol-melamine, and the catalyst ammonium chloride. The impregnated and aged pulp may, if desired be washed free of catalyst, dewatered, air-dried and stored for slurrying and use at a later time. In this case, catalyst must be added at this time unless the slurry is sufficiently acidic. Usual papermaking additives, such as wet-strength resins and defoamers may be present.
