Title: Improvements in apparatus for developing latent electrostatic images
IPC: G03G15/08
Filed: 1956-12-19
Abstract: 846,141. Developing electrostatic latent images. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 19, 1956 [Dec. 21, 1955 (2)], No. 38661/56. Class 98(2) [Also in Group XVI] An electrostatic latent image is developed by means of a cylindrical brush which is arranged to pick up toner powder from an adjacent storage compartment, and is rotated at such a speed relative to the image surface that a continuous wiping action is produced between the brush hairs and the surface. As shown, the latent image is carried on a drum 16 and is developed by the brush hairs 71 carried on a cylinder, the lineal speed of the brush hairs being slightly greater than that of the cylinder. The brush hairs pick up toner powder from a tube 74, and the supply is maintained by a piston (not shown) which is continuously fed upwards by a variable speed motor. A casing 88 surrounds the brush con. tacting the hairs, and is provided with rods 86 to assist in producing the necessary triboelectric charges. The case 88 or the cylindrical core of the brush may be connected to a source of potential in order to control or even prevent the application of toner powder. The cylindrical core may be constructed with commutator segments 93 to which the potential is applied only in the region defined by radial lines 97 and 98. Mechanism is described to reciprocate the brush towards and away from the drum 16 as well as to rotate it, so that a combined stippling and wiping action is produced. In this embodiment, the toner is fed to the brush by a screw feed mechanism. Specification 766,426 is referred to. Reference has been directed by the Comptroller to Specification 774,433.

Abstract: 960,900. Purifying exhaust gases. OXY-CATALYST Inc. Oct. 30, 1961, No. 38821/61. Heading F1B. Exhaust gases are mixed with air at 96 and passed through two beds of the same catalytic material 86, 88, in series which beds are arranged so that they can be independently recharged with fresh catelyst. The catalytic material, in the form of pellets, is contained between three removable slotted plates 24, fresh material being supplied through chambers 60, 67, whilst spent material is removed through chambers 82, 84. The gases flow through the inlet 92 into an inlet chamber 16 of decreasing depth and after passing through the beds 86, 88, escape through an outlet 90. Reinforcing ribs 16, 18, running longitudinally of the upper and lower casing walls 4, 6, support the upper and lower plates 24 and a sliding sleeve 98 adjusts the amount of air admixed with the exhaust gases. The upper bed 86 contains less catalytic material than the lower bed 88 and the spent material from the upper bed is reusable in the lower bed. The catalyst comprises an actuated metal oxide carrier, such as alumina, beryllia, thoria, magnesia, or zirconia, impregnated with an oxidising metal or metal oxide such as platinum, palladium, ruthenium, rhodium, copper, silver, chromium, vanadium, manganese or iron. In a particular example pellets of activated alumina are impregnated by dipping in a mixture of copper nitrate and chromium nitrate and then heated to decompose the nitrates.

Title: Improvements in production of magnetic materials
IPC: C22C38/02
Filed: 1960-11-14
Abstract: A method of producing a silicon-iron alloy body, <TABS:0944937/C3/1> in which the majority of the grains have (110) [001] or (100) [001] orientation is characterized by the feature that the preferred orientation can be chosen by controlling the oxygen present at the surface of the body during the texture annealing step. For obtaining (110) [001] orientation the oxygen content at the surface should be <6 p.p.m.; for (100) [001] it may be over 6 p.p.m.  The atmosphere during texture annealing can be a noble gas, hydrogen or a vacuum, and an inert coating (e.g. magnesia) can be used to isolate the surface of the body during texture annealing.

Abstract: 1,113,322. Photo-electric speed measuring. DECCA Ltd. 6 Sept., 1965 [28 Sept., 1964 (2)], Nos. 39374/64 and 39445/64. Heading H4D. In Doppler-effect apparatus measuring the speed V of a reflecting object and utilizing a coherent visible or infra-red light beam from a laser, frequencies may arise in the laser which produce spurious signals affecting correct operation of Doppler beat frequency tracking circuits; according to the invention the transmitted light beam after it leaves the laser, or the reflected light beam, is modulated at a predetermined frequency of a different order to that of the Doppler beat frequency and means responsive to the latter in a sensitive device receiving light both reflected back from the moving object and directly from the laser is arranged to respond to signals containing components of the modulation frequency. The beam modulation may be effected by a Kerr cell or, as in the embodiments, by an apertured rotating disc. In one embodiment a first photocell 20, by mirror 12 or polarization prisms, receives both transmitted and reflected light whereas a second photo-cell 14 receives transmitted light only; the difference of the photocell outputs is fed to mixers 21, 22 also fed in phase quadrature from a voltage-controlled oscillator 34 in a frequency tracking arrangement incorporating a phase-sensitive detector 30 fed from a photo-cell 31 which produces an A.C. voltage at the modulation frequency. The frequency of oscillator 34 is measured, to give speed V, or may control the speed. To ensure correct locking of the frequency tracking arrangement a low-frequency sweep generator 36, a reference generator 38, a detector 40, and a relay 42 and associated contacts 37, are utilized; a lamp 39 is energized when relay 42 signals that tracking is correct. In another embodiment, Fig. 2 (not shown), the laser is of the kind having mirrors at the ends, a photo-cell receiving light directly from the laser and amplified reflected light from the moving object; the output by the cell feeds directly into mixers 21, 22.

Abstract: 986,288. Toothed gearing. S. SMITH & SONS (ENGLAND) Ltd. Dec. 18, 1963 [Oct. 22, 1962], No. 39976/62. Heading F2Q. [Also in Divisions G3 and H2] A time alarm or electric time switch actuator of the kind in which an actuating spindle 1 is manually rotated to tension a driving spring fixed to the spindle and on release is returned by the spring under the control of a timekeeping escapement in train with a pinion (not shown) which engages a gear-wheel 24 fast with the spindle, is arranged so that the wheel 24 disengages from this pinion during one part at least of the return movement, whereby a rapid actuating movement of the spindle to actuate the alarm or switch, is permitted, followed by further movement under control of the escapement. The teeth of gear-wheel 24 are cut away over a sector as indicated by full and dotted line. A superimposed gear sector 25 free on the spindle is movable relative to gear 24 between extreme positions determined by stop faces 38, 39 co-operating with a lug 37 on gear 24. A light spring (not shown) normally biases gear sector 25 to the extreme position shown in Fig. 3. The teeth of sector 25 partly overlap and coincide with the teeth of gear 24 in both extreme positions and the pinion can engage both gears simultaneously. Assuming that the spindle is wound clockwise to a position in Fig. 3 where the pinion engages only the gear 24, then on running down anticlockwise to a position where the pinion engages only the sector 25, gear 24 is freed from the escapement and can rotate rapidly to the position of Fig. 2 taking up the lost motion. Further rotation of the spindle under control of the escapement is then continued until sector 25 also disengages from the pinion, whereupon the spindle 1 is again permitted free rotation back to an initial position. In a modification, two spaced tooth portions of the superimposed sector overlap two cut-away portions of the gear 24, whereby two periods of rotation free of the escapement are permitted in addition to a third such period which takes the spindle back finally to its initial position. The pinion may be of the " kick-out " type to allow of winding the device. Specification 968,587 is referred to.

Abstract: 960,922. Photo-electric measuring. BRITISH IRON & STEEL RESEARCH ASSOCIATION, and DIGITAL ENGINEERING CO. Ltd. Feb 14, 1963 [Nov. 14, 1961; March 23, 1962], Nos. 40663/61 and 11209/62. Headings G1A and G1M. The invention relates to means for measuring the length of moving objects, which may emit radiation, such as hot steel billets. According to the invention in its broadest aspect two time intervals are measured, a first between the times when the front edge of an object passes first and second points spaced apart a known distance and a second between times when the front andtrailing edges of the object pass the first point. The object length can then be computed by means using these time intervals. In a particular embodiment a hot billet B moving in the direction of the arrow is sensed by a photo-cell PC1 as it passes a first point and a pulse from the cell is fed to control unit CU and to start the operation of two integrators, I1 and I2. When the front edge of the billet reaches a second point viewed by cell PC2 unit LU is pulsed to stop the charge of integrator I2 and to disconnect it. Finally when the rear edge of the billet reaches cell PC1 the charging of I1 is terminated and the control unit allows both integrated voltages to be fed to dividing unit DU the output of which is a voltage proportional to billet length indicated at ID. When the division has been effected a signal is passed back to the control unit to reset the apparatus for another measurement. To minimize errors due to variation in the object's velocity of travel a plurality of detector cells may be placed at intervals of L units along the direction of travel and the length of the object determined as L times the number of cells affected less one, plus L times the ratio of the time interval between the passage of a leading edge over a cell and the next succeeding passage of trailing edge over a cell and the time interval between the front edge passing two adjacent cells. In the arrangement the length of each object may be measured a number of times and registration made conditional on substantial agreement of the results. Another way to minimize speed variation is to make the distance between the two points substantially the same as the expected length of the objects. The objects may intercept radiation normally falling on the photo-cells or means other than photo-cells be used to detect the passage of the ends of an object.
