Abstract: 894,510. Transformers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 1, 1959 [Dec. 16, 1958], No. 40599/58. Class 38 (2). [Also in Group XIII] Oil, used, for example, to cool a pulse transformer or other electrical equipment, is cooled by providing a substantially vertical cooled surface in contact with the oil, and heat-conducting members extending into the oil so shaped that the oil is caused to circulate rapidly adjacent the cooled surface, so that a thick layer of cold oil cannot form on the surface. The heat-conducting members 8 have a Z-shaped cross-section and are arranged horizontally across the cooled surface which is the wall 1 of the tank containing the oil. In a second embodiment the members are arranged obliquely on the walls (Figs. 6 and 7, not shown). The outer surface of wall 1 may be cooled by passing water or another fluid through pipes 7. The Provisional Specification also describes an arrangement with vertical cells, and also an arrangement with both vertical and horizontal cells. This subjectmatter does not appear in the complete Specification.

Title: Projection television system

Abstract: 1,080,540. Light modulating. GENERAL ELECTRIC CO. Oct. 9, 1964 [Nov. 7, 1963], No. 41406/64. Heading H4F. In apparatus for modulating light utilizing a deformable liquid medium 11 which is scanned in raster pattern 27 by an electron beam modulated so as to lay down charges that form diffraction patterns means are provided for increasing or decreasing the charge density on the liquid at the leading edge 35 of the raster for the purpose of smoothing the liquid and thus reducing the noise in the light beam which is projected through the deformable medium. In Specification 965,593 the charge density at the leading edge 35 of the raster is increased by a differentiating circuit operating on the lagging edges of the horizontal blanking pulses to produce pulses which are applied at the initiation of each horizontal trace to the control grid 14 of the electron beam device 12. In the present Specification the horizontal blanking pulses from circuit 26 are first amplified in device 50 and passed via wave-forming network 35 and capacitor 66 to the control grid 14. Network 35 comprises a pair of parallel circuits connected in series, one of which includes resistor 60 and variable capacitor 61 and the other of which includes resistor 62 and capacitor 63 (shown dotted since it may represent stray capacitance). When the capacitance of capacitor 61 is larger than that of capacitor 63, network 35 differentiates the blanking pulses, Fig. 2c, not shown, and pulses of short duration are produced at the termination of the blanking pulses of opposite polarity thereto at point 65 which increase the charge deposition. For deformable mediums of low viscosity the capacitance of capacitor 61 is adjusted to be smaller than that of capacitor 63 and network 35 thus integrates the blanking pulses, Fig. 2D, not shown, and pulses of short duration are produced at the termination of the blanking pulses of the same polarity thereto at point 65 which decrease the charge deposition. These short pulses may be precisely controllable with respect to amplitude and duration and do not appreciably affect charge deposition during the trace interval. During the vertical retrace intervals the electron beam is blanked by means of amplifier 53 which is fed with vertical blanking signals.

Filed: 1973-09-05
Abstract: 1429017 Printers INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1973 [21 Sept 1972] 41641/73 Heading G4H In an ink jet printer, charging of a given ink drop is modified to compensate for the effect of at least one preceding drop upon the given drop. The modification may be by adding to the charging voltage, weighted versions of the charging voltages applied to preceding drops, obtained from delays. Alternatively, a staircase voltage is applied to a voltage divider, a tap or taps of which are selected by the stages of a shift register to feed an analogue OR gate which passes the largest of its inputs as the charging voltage. The shift register is fed from a character generator specifying for each position in a character dot matrix whether a drop of ink is required there or not. Alternatively, the modification is obtained by feeding the charging voltage via an RC network the output of which is sampled and held at the precise instant that it gives the correct compensation.

In an alternative embodiment the extension 24 protrudes externally of the intake 20 and is electrically heated to melt the solder. To extract the solidified solder, the rod 22 is moved beyond the cocked position until an end fitting 14 is forced out of the body 12. The piston assembly may be replaced by a tubular member 70 (Fig. 3) which is held by a trigger 80 engaging under a flange 78 In a further embodiment (Fig. 4, not shown) the plunger rod passes through a gland and when the device is cocked a vacuum is formed behind the piston.

Abstract: 1389830 Telemotors COVENTRY CLIMAX ENGINES Ltd 26 July 1972 [8 Sept 1971] 41996/71 Heading F1P [Also in Division F2] A remote control actuator for a plurality of hydraulic control valves, such as those used on a fork-lift truck, comprises a body member 11 defining a plurality of cylinders 12 at least equal in number to the plurality of valves. Each cylinder 12 accommodates a double-acting piston 13 which is movable by a manually operated lever 31 pivoted at 34, and communicates via closable ports 25 and 27 with manifolds 26 and 28, respectively. Movement of the lever 31 in the direction of arrow A, results in piston 13 being moved to the left, as seen in the drawing, from its control or neutral position to which it is biased by spring 18. Accordingly, port 25 is closed and the pressure in output. port 29 is increased consequent to the compression of fluid by piston 13. Simultaneously, outlet port 30 is in unrestricted communication with port 27. Thus, outlet lines 39 and 40 are at different pressures and these pressures are transmitted to the opposed ends of a speed valve, Fig. 3 (not shown) which is biased to a central or neutral position and which controls the flow of fluid between two inlet ports, two work ports and two drain ports. Return of lever 31 to the position shown returns the piston and hence also the spool valve to its neutral position.
