Abstract: 1,084,869. Grinding. CORNING GLASS WORKS. May 11, 1965 [May 11, 1964], No. 19840/65. Heading B3D. A method of removing the parting lines from edge portions of a workpiece 40, such as a pressed or moulded cup or bowl of glass or other material, and providing a smoothly-rounded edge thereon comprises rotating an abrasive element 10 about a first axis and in engagement with an edge portion of the workpiece rotating about a second axis so as to form a planar annular surface on the edge of the workpiece, and then rounding at least one corner of the annular surface. The abrasive element is in the form of a spool having a peripheral abrasive face 10 and two radial faces 11, 12, and is driven by an electric or pneumatic motor 14 carried by an arm 15 mounted on a pivot 16, a weight counterbalancing the weight of the motor. The arm can be retained in a first position during the grinding of the planar surface by a solenoidactuated plunger 19 engaging a hole 20 in the arm and can be resiliently urged in one direction or the other so that the radial faces 11, 12 form the rounded edges of the planar surface by pneumatic cylinders 42, 44 when the plunger is retracted from the hole, a block 22 having a recess engaged with clearance by a projection 23 on the arm being movable by a rack-and-pinion mechanism 24, 25 operated by a pneumatic actuator 26 to control the rate of movement of the arm and to permit free floating movement of the arm, and hence the abrasive element, during grinding of the rounded edges. The article, such as a cup or bowl, is carried by a lower chuck 27 mounted on a shaft 28 driven by a belt 30 from an electric motor 29, and an upper chuck 31 is freely rotatable on a shaft 32 of a pneumatic actuator 33, the shaft extending through a stop plate 38 and being formed with a stop element 39. The plate is movable downwardly to control the feed rate of the workpiece at a speed determined by movement of an end cap 37 on a shaft 36 which can be engaged by a clutch 35 with a shaft 34 driven by the belt 30. The shaft 36 can also be rotated rapidly to raise the plate 38 and upper chuck by an actuator 45 connected by a rack-andpinion mechanism 46, 47, shaft 48 and gear mechanism 49 to the shaft 36.

Title: Improvements in apparatus for electrostatic precipitation
IPC: B03C3/38
Filed: 1962-05-24
Abstract: 962,773. Electrostatic precipitators. GENERAL ELECTRIC CO. May 24, 1962 [May 26, 1961], No: 19993/62. Heading B2J. In apparatus for precipitating dust particles from a gas stream by electrically changing and suspending the particles in the stream, the apparatus includes spaced electrodes between which the gas stream passes and on which the particles are deposited by electrostatic action and at least one electrode is formed with two planar exterior surfaces diverging from each other in the stream direction and gradually approaching adjacent other electrodes, the two surfaces being shaped so as to meet at their ends to form a closed body structure where the stream flow is non-turbulent. In the arrangement shown the precipitator comprises a collector chamber 12 and two cleaning chambers 13, 14 from which chambers 13, 14 dirt is removed by hoppers. The arrangement shown has two stages and each stage has at its entrance end a flame charging member 15 or 16 followed by an electrode structure made up of a plurality of collector-electrode members 17 or 18 of approximately twice the width of the chamber 12. The flame charging members 15 or 16 are made up of a plurality of perforated pipes 21 extending between upright pipes 22, 23 connected to a source of gaseous fuel. The perforations are formed in each pipe along the length of the pipe and on the downstream side. The collector-electrode members 17, 18 are hollow and are supported in plates 25, 26 mounted on rollers 30 movable in channels 32. The collector-electrode members 17, 18 are continuously moved transversely of the chamber 12 and between electrode members 29 by electric motors 33, 34 through cables, and between rotating brushes. 51. The members 29 are held by means of suitable bushes in side members 31 and the collector members 17, 18 and members 29 are shaped so that the crosssection of the fluid flow path is gradually decreased in the collector region to ensure a stream line or laminar flow of the fluid through the region. A number of small openings may be provided along the leading edge and other critical spots of the members 17, 18 for the removal of air which is pumped out of the inside of such members 17, 18 at a very slow rate to facilitate the flow of air over the outside of such members. Suitable electric potentials are applied to the flame charging pipes 21 and electrode members 29 and the collectorelectrode members 17, 18 are grounded to the outer casing 11 or are at a potential of opposite polarity to that applied to the pipes 21 and members 29. Suction motors provided near the bottom of the cleaning chambers 13, 14 remove any air laden with dust, which is not removed from such chambers by the hoppers, and return such air to the upstream input side of the precipitator.

Title: Improvements in or relating to limiting circuits
IPC: G09B9/20
Filed: 1959-07-31
Abstract: 922,414. Valve non-linear circuits. ACF INDUSTRIES Inc. July 31, 1959 [Aug. 11, 1958], No. 20446/60. Divided out of 922,413. Class 40 (6). [Also in Group XXXVI] A non-linear amplifier which delivers an alternating output whose amplitude varies as shown in Fig. 2, with the amplitude of the alternating input on a line 22 representing elevator deflection in a grounded aircraft trainer, as described in Specification 922,413 [Group XXXIII], comprises a first diode circuit including diodes 26-36 which prevents the application of the input signal to amplifier 24 when it is within limits determined by reference A.C. potentials applied at 42 and 44 and a second diode circuit including diodes 70-80 which is in a negative feedback path around amplifier 24, so that, when the input signal falls outside limits determined by further reference A.C. potentials applied at 82, and 84, heavy negative feedback is applied to amplifier 24 to maintain the output substantially constant. The phase of the input signal on line 22 may have either of two values, referred to as positive and negative, depending upon whether the value of the quantity it represents is positive or negative. Likewise, the reference potentials applied at 42 and 82 are of negative phase while those applied at 44 and 84 are of positive phase, those at 82 and 84 being of equal magnitude but those at 42 and 44 differing in magnitude from each other. So long as the signal on line 22 lies between both as regards magnitude and phase, the limits imposed by the potentials applied at 42 and 44, diodes 26, 28 remain biased off. However, since the reference potentials are of different magnitudes, a backing-off potential equal to the difference between the reference signals but of opposite phase is applied at point 54 to leave a zero resultant signal at the input to amplifier 24. When, however, the input signal becomes of greater amplitude than the reference signal of the same phase, the difference appears at the input of amplifier 24 which has a gain determined by the negativefeedback resistor 64. The amplifier output is applied to the input of a diode circuit, similar to the one to which the input signal was applied; hence an output from this circuit is applied to the amplifier input only when the output of the amplifier exceeds, as regards magnitude and phase, one of the reference potentials applied at 82 and 84.

Title: Improvements in Internal Combustion Engines.
Inventor: MOUGEOTTE GASTON
IPC: F01L7/02
Filed: 1918-12-11
Abstract: 121,605. Mougeotte, G. Dec. 17, 1917, [Convention date]. Valves.-Cylinders are disposed radially in a number of substantially parallel planes each containing an even number of cylinders, the distribution being controlled by rotary valves located between the heads of cylinders disposed in adjacent radial planes. Fig. 1 shows one of the parallel planes of an engine having sixteen cylinders. Rotary cylindrical valves x<1> each control the cylinders in a pair of planes radial to the crank-shaft. Each valve has a pair of inlet ports o and a pair of exhaust ports g; the inlet ports communicate with annular passages x and the exhaust ports with central chambers z. Cooling water is circulated through the chambers y. The valves are packed with rings (not shown) and with strips e disposed parallel to the axes of the valves. The packing is held in contact with the valves by the pressure of the lubricating oil which acts upon the faces of the packing remote from the valves. Lubricating oil for the valve mechanism is supplied by a pump having its inlet orifice located above that of a pump which lubricates other parts of the engine. In the event of the oil in the supply tank b running out, the pump supplying the valve mechanism is cut out before the other pump. The packing-members are thus relieved of pressure and seizing of the valves is prevented. A valve-controlled by-pass is located in the lubricating-oil system and the spring of the valve is connected to a valve in the carburettor so that the pressure of the lubricating oil varies with the quantity of charge delivered to the engine.
