Abstract: A method and apparatus for canceling both earseal and hybrid echo in a Wireless Local Loop telephone system is disclosed. The present invention operates within a subscriber station having a plurality of telephone inputs, one of which is a dedicated handset and at least one other input being a standard analog telephone. During a conference call between a far end speaker and two near end speakers, the far end speaker may hear an echo of his own voice due to an earseal echo generated by the dedicated handset and a hybrid echo generated by a 4-to-2 wire hybrid interface within the subscriber station. In accordance with the present invention, two distinct echo cancellers are used in the subscriber station to reduce the two types of echo. A first echo canceller is optimized to remove the earseal echo generated at the dedicated handset while a second echo canceller is optimized to remove the hybrid echo generated at the 4-to-2 wire hybrid. The two echo cancellers operate independently such that neither echo canceller need adapt its filter coefficients when a change in the echo channel characteristics occur, such as when a speaker hangs up or another speaker joins the conversation.

[Also in Division G1] A light-sensitive photographic material comprises a support coated with two light-sensitive silver halide emulsion layers, one of which is sensitive to blue light but not to red or green and contains red-, green-, magenta-, or cyan-forming colour coupler and the other emulsion is sensitive to red or green light, so that each emulsion can be exposed without exposing the other emulsion, and contains colour coupler which forms a colour complementary to that formed by the first emulsion. The material is used to record three different light signals, for example beams reflected from three galvanometer mirrors, one signal being in blue light and giving a red, green, magenta or cyan trace on one emulsion of the photographic material after colour development, a second signal being in red or green light and giving a trace on the other emulsion in a colour complementary to the first trace and the third signal being in light containing both blue and red or green light (e. g. white light) and giving a trace on both emulsions appearing as a grey or neutral colour. The emulsions of the photographic material may be on the same or on different sides of the support and an interlayer may be coated between them which may contain a non-diffusing developing agent such as hydroquinone or a derivative thereof. A bleachable filter dye may also be situated between the emulsions, possibly in the interlayer. The emulsions may each comprise more than one coating of emulsions of different speeds and the colour couplers may comprise a mixture of two colour couplers to produce the desired colour i.e. either one red-forming coupler or a mixture of magenta- and yellow-forming couplers, or one green-forming coupler or a mixture of yellow- and cyan-forming couplers may be used.

Abstract: 1,234,210. Measuring pressure electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct.23, 1968, [Nov. 2, 1967], No.49813/67. Heading G1N. In an electromagnetic induction flowmeter (10), Fig. 1 (not shown) to monitor the flow pressure of a liquid metal, a resistance shunt 17 is provided on the exterior surface of the duct 13 to connect the electrodes 27, the resistance of which shunt is chosen to be equal to that of the path between the electrodes through the liquid metal. The dimensions of the duct are chosen so that the hydraulic pressure drop is low e. g. less than one per cent of the applied pressure, whereby the opposing pressure due to the induced current is approximately equal to the applied pressure. Thus the applied pressure is determined from the potential drop across the shunt which is a layer of copper or silver.

Abstract: 1,250,416. Supporting magnetic heads. PERIPHERAL SYSTEMS CORP. 10 Feb., 1969 [22 March, 1968], No. 7068/69. Heading G5R. A magnetic head is supported adjacent a magnetic disc by an access arm 20 having a resiliently deformable portion and adjustably clamped 22 to a movable support 24, and having a ramp co-operable with a stationary cam to lift the head from the disc when the support 24 is retracted. As shown, a bank of flying heads are mounted on a carriage 24 movable through an archway 80 carrying circuit boards 82 when an address current is passed through a coil 34 fixed to the carriage and movable in a permanent magnet housing 32. A tachometer 132 supplies control circuitry (Fig. 11, not shown) to slow the carriage as it approaches the selected track, and a solenoid (110) is released to allow a pawl assembly 40 to engage a rack 42 on the carriage. The assembly 40 comprises two pawls (114a, 114b, Figs. 7-9, not shown) spaced along the rack so as to double the number of track positions. A variable reluctance transducer (120) adjacent the rack senses its location at any instant. Each head 100 is located in an apertured ceramic pad 104 spot-welded 94 to a support 90 itself spot-welded 98 to the arm 20. The arms 20 are stacked in horizontal pairs associated with different discs, and tabs 85 engage to prevent the arms moving excessively under their inherent bias. In a modification, the rack and pawl mechanism is dispensed with and the heads are positioned using a control track either on a control disc or in a permanently recorded layer under an information layer, or by using the data, when in NRZ form, itself. Two heads (101a, 101b, Fig. 4, not shown) having opposed windings are located upstream of the head 100 and scan lateral halves of the tracks so that zero output indicates to the circuitry that the head is aligned, while the varying output as the head is moved provides a signal for comparison with that selected.

Abstract: 1,251,400. Fuel elements. ATOMIC ENERGY OF CANADA Ltd. 23 May, 1969 [4 June, 1968 (2)], No. 26568/69. Addition to 1,118,850. Heading G6C. A fuel element comprises a core of U metal alloyed with from 2 to 7À3 wt. per cent Si, the core containing one or more void spaces, and a sheath of corrosion resistant alloy, e.g. Zr alloy. The core is heat-treated so as to form a corrosion-resistant alloy, preferably the delta phase U 3 Si. The total volume of the void space(s) is between 3 and 25%, preferably 15%, of that of the U-Si alloy, its purpose being to accommodate any swelling of the alloy and also the fission products produced. The fuel element is fabricated by one of the following methods: (a) casting the U-Si alloy in the form of a rod having a central void, heat-treating the rod at 750 to 900 C. for 2 to 300 hours to peritectoidally transform the alloy to the delta (U 3 Si) form, machining the rod to predetermined dimensions, and slip fitting the rod into a protective sheath; (b) casting the U-Si alloy in the form of a billet, heat-treating the billet at 750 to 900 C. for 2 to 300 hours to peritectoidally transform the alloy to the delta phase, extruding the billet at less than 930 C.(the peritectoid temperature) such that a void is formed in the rod, machining the rod to predetermined dimensions, and slip fitting the rod into a protective sheath; (c), as (b) above, but extruding the billet before the heat-treatment; (d) casting the U-Si alloy in the form of a billet, heat-treating the billet at 750 to 900 C. for 2 to 300 hours to peritectoidally transform the alloy to the delta phase, and co-extruding the billet inside a corrosionresistant sheath at less than 930 C. to form a U 3 Si core having a central void; and (e), as (d) above, but co-extruding the billet before the heat-treatment. A plug of U 3 Si may be bonded to one or both ends of the core so that the void is enclosed by the core. The U-Si alloy may alternatively be cast as a rod having a uniformly dispersed porosity produced by the introduction of an inert gas, e.g. helium, as by bubbling the gas through the molten alloy or exposing the molten alloy, typically at 1500 C., to an atmosphere of the inert gas so that sufficient of the inert gas is absorbed by the alloy, or by placing a gas-generating liquid or solid, e.g. magnesium, in the mould cavity in which the core is to be formed. The rod is heat-treated as in method (a) above to transform it peritectoidally to the delta phase and then machined to its final dimensions before being slip fitted into a protective sheath.
