Filed: 1972-02-01
Abstract: 1361687 Laying fabric CUTTERS MACHINE CO INC 1 Feb 1972 [18 March 1971] 4587/72 Heading D1S A speed reducing apparatus for a fabric laying machine 10 having a frame 11 supported for reciprocation over a laying table 14 between reversing stations, a fabric laying unit 21 and means for supplying fabric 17 to the unit 21, comprises (a) electrically energized motor drive means 28 for moving the frame 11 over the table 14; (b) speed control means for selectively energizing the motor 28 to move the frame 11 at a low speed or to move the frame 11 at a high speed substantially faster than the low speed; (c) a dynamic braking circuit 46 connected to the motor 28; (d) low speed switch means communicating with the dynamic braking circuit 46 and with the speed control means, the low-speed switch means being adapted, when actuated, to energize the dynamic braking circuit while the back EMF of the motor 28 is above a pre-set value corresponding to the low speed, to condition the speed control means to de-energize the motor 28 while the dynamic braking circuit 46 is energized, and to condition the speed control means upon de-energization of the dynamic braking circuit to energize the motor 28 in the low speed; and trip means 55, e.g. a ramp, for actuating the low speed switch means while the frame 11 is moving toward a reversing station. Automatic energisation of the dynamic braking circuit 45, upon signal, causes the motor 28 to be decelerated down to, but not below, the pre-set low speed, at which time the circuit 46 is de-energized and the speed control drive mechanisms are re-energized to drive the motor 28 at a constant low speed. The low speed switch means comprises a trigger circuit 47 including a pair of low speed switches 49, 50, a speed selector switch 62 having a high position and a low position and a dynamic brake switch 70. The switch 62 communicates with the speed control means to selectively energize the motor 28 in high speed in high position and low speed in low position and the switch 70 is adapted to energize the circuit 46 when closed. The switch 62 is in low position and the switch 70 is closed when the switch 49 or 50 is actuated. The dynamic braking circuit 46 comprises an SCR 72 in series with a braking resistor 73 and a transistor 74 to apply a constant voltage upon the circuit 46 corresponding to the low speed and opposite in direction to the back EMF so that the SCR 72 turns off when the back EMF is equal to or less than the constant voltage, the switch 70, when closed, being adapted to turn on the SCR 72. A Zener diode 75 is connected in the base-collector circuit of the transistor 74 and a resistor 76 is connected in the base-emitter circuit of the transistor 74. While the circuit 46 is energized, a signal is transmitted to a stop-start control circuit 38 to close a switch in a clamping circuit 80 so that a motor speed control circuit 37 is de-energized so that an SCR bridge circuit 45 is not fired, regardless of the setting of the switch 62, so that the motor 28 is not driven.

Title: Improvements in apparatus for heating by high frequency electric energy
IPC: B29B13/00
Filed: 1944-03-16
Abstract: 580,374. Electric induction heating. BRITISH INSULATED CABLES, Ltd., QUAYLE, J. C., and JONES, P. March 16, 1944, No. 4886. [Class 39 (iii)] In apparatus for heating material by a high frequency electric field between two electrodes 1, 2, a conductive wall 12, 14 electrically connected to the peripheries of the two electrodes encloses the adjacent region to form with the electrodes an electric resonator which is readily operable for inserting the material through a part 14 of the wall which may be hinged at 15. The electric and magnetic fields are thus confined to the enclosed region and radiation of energy is prevented. The spacing of the wall in a direction parallel with the electric field is preferably greater than the spacing of the electrodes, as shown. The electrodes 1, 2 may be the plates of a press supported on four pillars 6, the lower one 2 being insulated therefrom, and capable of up and down movement by making the wall of flexible copper sheeting or alternatively, of two slidably connected portions, Figs. 5, 6 (not shown). High frequency energy may be applied by coaxial cables 23, the outer conductor being earthed and connected directly to the casing, while the inner conductor 24 is connected to a looped tube 36 inductively coupled with the resonant system. Alternatively both electrodes may be insulated from earth, and leads brought through the middle of the casing are connected either directly to the electrodes, Fig. 7 (not shown), or to points on 'the wall itself to provide a step-up in the applied voltage. The invention is stated to be applicable where the maximum dimension of the electrode surfaces is greater than or equal to a quarter wave length.

A grinding roll of a roller mill has its shaft carried at each end in a journal unit which comprises a bearing of the type in which two rows of rollers with their cages are retained in an outer race or races which space the rows of rollers apart, whilst the outer assembly (comprising the rollers and their cages, races and housing) is free to slide along the inner race or races which is or are secured to the shaft, the inner roller tracks having between them a part constituting a spacing ring (which may be integral with or separate from the inner races) which is of the same external diameter as or of less diameter than the inner roller tracks and can serve as a journal surface in a machine tool when the outer assembly is not in position and the roll is to be machined. The roll b is mounted on a shaft a which has a sleeve c shrunk thereon. A collar m is provided to facilitate the withdrawal of the sleeve. The extremities of the outer surface of the sleeve c constitute bearing surfaces for rollers d, supported in cages e and retained in outer races f. In the embodiment shown the races f are carried by a housing g though in another embodiment, Fig. 3 (not shown), the inner surface of the housing g may be ground to form the outer race for the rollers d. In both embodiments the periphery of the housing is formed with a part-spherical seating carried within two co-operating. rings i and j  which are retained against a shoulder n by a thrust-ring k. It is an object of the invention that the outer surface of the sleeve c may be held on its central part in a machine-tool to enable the periphery of the roll b to be machined and the rollers d and housings g may then be assembled by sliding them axially on the sleeve when the roll is to be mounted in its position of use. Instead of a unitary sleeve c; separate inner roller races and a spacing sleeve of the same or less diameter may be used.

IPC: F16K17/10
Filed: 1962-02-08
Abstract: 951,007. Fluid-pressure servomotor control systems. BORG-WARMER CORPORATION. Feb. 8, 1962, No. 4959/62. Heading G3P. A pressure relief valve comprises a valve body 17 mounted in a housing 10 which has an inlet 11 and an outlet 12. The body 17 has a valve seat 25 for a relief valve closure 26, located outside the body, and formed with or fixed to a domedshaped skirt 31. The valve member is connected by a rod 27 to a piston 35 slidable in the body 17 and bores 37, 38 extend through the valve member rod and piston assembly. The bore 38 telescopically receives a hollow tubular member 39, fixed to the body 17 and formed with a valve seat 45 for a pilot valve closure 46, the member 46 being loaded by a spring 73 and controlling flow of fluid from the inlet 11 through the bores to a chamber 77. The piston 35 is loaded by a spring 79 towards the relief valve closed position and either side of the piston is vented through ports 80, 83. When the inlet pressure opens the pilot valve 46, fluid flows to chamber 77 and acts on piston 35 to open the relief valve. The skirt 31 allows only a small flow from the inlet to ports 17a when the relief valve cracks open and consequently a large stroke of the valve is necessary to relieve pressure thus preventing chattering. Movement of the relief valve does not vary the loading of the pilot valve which is thus substantially constant. The skirt 31 may be formed by a series of frusto-conical surfaces.
