Abstract: 1,225,272. Mass spectrometers. GENERAL ELECTRIC CO. 6 March, 1968 [27 March, 1967], No. 10977/68. Heading H1D. In a mass spectrometer employing a quadruple type analysing field comprising a ring electrode 1 and a pair of electrodes 3, 4 defining an ion containment region 10, ions of a selected mass are trapped in the region 10 and periodically released to an ion-collecting electrode or electron multiplier 9 by applying a negative pulse to the electrode 3. An H.F. voltage is applied to the electrode 1 and electrodes 3 and 4 are maintained at a negative D.C. voltage relative to the electrode 1. In addition, electrode 4 is biased slightly positive relative to electrode 3. The ions are generated in the region 10 by a pulsed electron beam from gun 11, 14. The surfaces of electrodes 1, 3 and 4 are hyperboloidal, but may be part-spherical (Fig. 4) and the electrodes may be solid or of mesh form. In alternative embodiments a beam of ions may be admitted to the region 10 from a conventional ion source through a central aperture in the lower electrode 4 or diagonally to the centre line of the electrodes. The ions may emerge into the containment region through a snout (61, Fig. 6, or 71, Fig. 7) insulated from the electrodes.

Abstract: 1,238,326. Filter. N. O. ROSAEN and B. O. ROSAEN. 13 Aug., 1968 [21 Aug., 1967; 14 March, 1968], No. 38583/68. Heading B1D. A filter comprises two semi-cylindrical, pleated, wire cloth filter elements mounted on opposite sides of a partition 26 which is periodically rotated in response to clogging of the element in chamber 34, which communicates with inlet 18 and outlet 20 for liquid being filtered, to move the clogged element into chamber 36, wherein its outer, upstream surface is continually subjected to a jet of filtrate delivered from connection 122 by pump 124 to nozzle 128, the clogged element being also backwashed, when it comes to rest in chamber 36, by filtrate injected through passage 104 from a cylinder 100, whose piston (106) (Fig. 1, not shown) is advanced against spring-loading by fluid pressure. Clogging of the operative element is detected and externally indicated by device (130) illustrated in Figs. 3, 6 (not shown) which incorporates a pressure-operated by-pass valve, and movement of the indicating needle closes a switch (158) to start the motor which rotates the partition and elements. A simple circuit (Fig. 5, not shown) keeps the motor running until the elements have turned almost 180 degrees, the movement being completed by intertia after a cam 86 has opened switch (160). Piston (106) is advanced automatically once the elements come to rest. Cylinder 100 has an air bleed valve which is held open while the filter is operating and thereafter closed to prevent drainage of the liquid from the cylinder. A solids-receiving sump 96, transparent inspection window 92 and housing drain valve (90) are provided. The filter elements are secured to the partition by sliding C-clips engaging respective pairs of J-clips (Fig. 3) and are supported between perforate retainers. Spring loaded vanes (46, 50) seal between the partition and the housing. Figs. 7 to 13 (not shown) illustrate a second embodiment, connected in a closed circuit which includes a reservoir and a machine tool, supplied with coolant from the filter. A pump (280) delivers filtrate from the operative element to the nozzle (285) and to the backwashing cylinder (242) alternately through a two-way valve (282) (Fig. 9), the nozzle directing filtrate on to the upstream face of the elements only while they are moving. During backwashing of the inoperative element a valve (256), closed during element movement, opens and solids and backwashing liquid pass down conduit (248) into a felt bag (252), through which liquid filters into the reservoir (Fig. 7). Fig. 13 illustrates how the fluid pressure in the filtering chamber (232) is applied to the rear edges of the sealing vanes, of which one is metal and one rubber, a ball valve (340) moving along passage (334) to isolate the cleaning chamber (234). The ends of the filter element and partition plate assemblies make sliding contact with bearing plates, liquid leaking into lower bearing (306) is bled off into the cleaning chamber, and liquid being filtered is forced through the filter by an upstream or downstream pump.

A dry type electrostatic latent image development apparatus comprises a plurality of rotatable rollers 21, containing conductive material and acting as development electrodes, which are spaced by a small distance from a photo-conductive layer bearing a latent image located on the surface of a drum 1. The rollers are spaced from each other by a distance smaller than the diameter of the carrier particles in a developer 31, which is fed to the rollers 21 on the side facing away from the drum 1, by means of an endless conveyer 33. The toner particles adhere to the rollers which may be of the same material as the carrier particles and are transferred to the drum 1 thereby. The carrier particles, which cannot pass between the rollers 21, fall back into the development unit 3. In another embodiment the rollers are spaced between each other by a distance exceeding the diameter of the carrier particles but a screening plate (4) Fig. 5 (not shown), prevents the carrier particles from reaching the drum 1. A magnetic brush may be used to apply developer to the rollers.

Abstract: 1,252,201. Demagnetizing cathode-ray tube apparatus. SONY CORP. 17 April, 1969, No. 19676/69. Heading H4T. [Also in Division H1] An arrangement for demagnetizing a cathoderay display tube provided with beam selecting means 17 (Fig. 1), e.g. an apertured mask or grill adjacent the screen, comprises a shroud 16, Figs. 1 and 2, formed of a material having a high magnetic permeability (e.g. annealed steel) and provided with two pairs of slots of which one pair 19a, 19b is shown in Fig. 2 (the other pair, not shown, being at the other side of the tube) and in each pair of which coils 11a, 11b (see also Fig. 1) are wound. The apertured mask or grill 17 (see also Fig. 6) is supported in the tube by means of a frame 18 of high magnetic permeability such that when an apertured grill is employed the longitudinal axis of the parallel slits 17a extends between the two coils (from top-to-bottom as shown in Fig. 1). The coils are connected in series and connected via a thermistor 21 and a varistor 22 (Fig. 7) with the output of the mains transformer 20 which supplies an operating D.C. voltage via rectifier 23 to other devices in e.g. a television receiver. When the latter is switched on A.C. flows initially through the coils 11a, 11b via the varistor 22 the resistance of which gradually increases as the resistance of the thermistor 21 decreases due to the heating effect of the current. A demagnetizing cycle is thus produced as the A.C. flow through the coils is gradually reduced to zero and the full transformer voltage becomes effective at the rectifier. In a modification (Figs. 3 and 4) a peripheral ring 26, 26a of high magnetic permeability forming an addition to the magnetic circuit surrounds the front of the tube and provides an enhanced demagnetizing effect in addition to serving as an anti-implosion band.

The incoming P.C.M. signals are supplied via a delay Vg to a plurality of gates G1 to G8, corresponding to the number of bits in a test word, which are controlled by a test word generator PG via switches S1 to S8 sequentially operated by a pulse distributer Iv controlled by a pulse generator IG. The outputs of gates G1 to G8 are supplied to a stage AS which produces an output A when there is coincidence between the received test word and the locally generated test word, indicating synchronization. Non-coincidence produces an output B which is used in a manner unspecified to alter the frequency or phase of the pulses from generator IG or to adjust the delay Vg. A combination of these measures may be used. Thus adjustment will continue until the error signal B ceases. Monitoring of synchronization may also be effected by the insertion of a test word in idle channel time slots.
