Title: Waste disposer
IPC: E03C1/266
Filed: 1963-07-22
Abstract: 972,222. Waste disposal apparatus. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. July 22, 1963 [Sept. 10, 1962], No. 28888/63. Heading B2A. A waste disposer for a kitchen sink comprises a cutter ring 23 surrounding an impeller disc 22 on which is pivotally mounted a hammer 46 having a part 53 with an outer face extending generally adjacent the cutters on the ring, and means associated with the part 53 for causing the latter by the action of centrifugal force to present a leading edge of the outer face to the cutters as the impeller disc is rotated. The impeller disc 22 has a dished centre portion and is mounted on the shaft 18 of an electric motor carried by a two-part casing 14, 15 supported by a vibration absorbing mount 11 from the drain sleeve 10 of the sink. The cutter ring 23 is formed with cutters 35, which are inclined at approximately 15 degrees, and mounted in a central cast part 17 having a part 21 for connection to a drain. The cutters co-operate with a pair of hammers which comprise upper and lower parts 53, 54 joined by a journal 55, the impeller disc being formed with openings 44 which permit the passage of one of the parts during assembly of the impeller and have semicircular ends 45 acting as part bearings for the journals. A keeper plate 50 is secured to the shaft of the motor and has semicircular parts 51, which complete the bearings for the journals, and cut-outs 51a which engage the ears 41 of a nut 40 for retaining the impeller disc on the shaft 18 of the motor. The hammers, which may be cast metal, have their upper and lower parts offset so that, under the action of centrifugal force upon rotation of the impeller, the leading edge, which may have a hardened tool steel insert, is adjacent the cutters 35. The central areas 56 of the upper parts of the hammers may be plain while the side areas are formed with steps 57, and the mass of the upper part of each hammer approximates to that of the lower part so as to balance the hammers about a horizontal plane. A modified form of hammer is made from metal which is bent to form a journal 64, Fig. 7, and has an upper part comprising three thicknesses of metal and a lower part comprising four thicknesses of metal so that centrifugal force acting on the hammer causes the leading edge 67 of the upper part to be adjacent the cutters. To prevent the material being comminuted rolling in a ball around the cutter ring, two of the teeth 35 are cut off as shown at 37. The cutter ring is bent to form a flange 26 and the impeller disc is provided with radial slots 39 and deformed adjacent thereto to provide projecting edges which cooperate with the portions of the teeth 35 of the cutter ring below the impeller disc.

Abstract: 1521295 Television receivers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 16 July 1975 [17 July 1974] 29764/75 Heading H4F A receiver for a television signal comprising colour signals modulated on quadrature carriers, one of which inverts in phase at line frequency, e.g. a PAL signal, includes a single synchronous demodulator fed with a constant phase reference subcarrier and the chrominance signal. The demodulator output is processed to provide at respective output terminals the one component and the other component of the colour vector along the reference subcarrier axis. As disclosed, Fig. 1, a burst gate 2 passes the colour bursts in a chrominance signal C to a gate 3 enabled at half line frequency so as to pass alternate bursts to a subcarrier generator 5. The generator feeds to the demodulator I a subcarrier which is in phase with the selected bursts. The output of the demodulator during each line therefore consists of portions of both the B-Y and R-Y signals. The output signals pass direct and via one-line delay 7 to a switch 6 which provides one component of the colour vector continuously at a terminal 8 and, simultaneously, the other component of the colour vector continuously at a terminal 9. The signals at 8, 9 are passed to a matrix circuit, Fig. 3 (not shown), which derives the R, G, B, signals.
