Filed: 1965-05-12
Abstract: 1,097,902. Reactors. SIEMENS-SCHUCKERTWERKE A.G. May 12, 1965 [May 13, 1964], No. 20128/65. Heading G6C. A guide tube or insulating tube for a fuel element in a reactor is made of a brittle material or material of low mechanical strength, and the wall of the tube is reinforced. The tube may be of beryllium, beryllium oxide, ceramic material, graphite, pyrographite, silica, or a sintered material. The reinforcing may be metal or glass fibre. The reinforcing may be attached to the tube by means of a collar around each end of the tube, or by means of a washer on each end face of the tube. The reinforcing comprises wires or small diameter tubes placed on the outer surface of the tube, inset into the outer surface, or entirely embedded within the tube wall. The wire may be arranged in parallel, axially extending lengths, in helices of the same or opposite hands, or in a combination of helices and straight lengths. Instead of individual reinforcing members, an integral metal wire or strip netting can be used, in which case it is possible to embed this in the material of the tube so that it extends throughout the tube wall thickness; a single thin walled metal tube may also be used. In order to obtain special properties, such as a low friction inner surface to the guide tube, composite tubes can be built from several layers.

Abstract: 852,742. Automatic voltage-control systems. GENERAL ELECTRIC CO. Ltd. June 26, 1958 [June 26, 1957], No. 20186/57. Class 38(4). In an automatic voltage-regulating system, a supply is controlled by means comprising a switch co-operating with a time-delay circuit so that above a predetermined output voltage the switch oscillates to maintain the output voltage constant. In an embodiment, a field 3 of an alternator 1 supplying a load 2 is controlled by a magnetic amplifier 4 fed from the output of the alternator. The current through a rectifier 6 to a control winding 5 of the magnetic amplifier is controlled by a switch comprising a coil 9 actuating an arm 8 against the pull of a spring 10. At a low rectified voltage the arm 8 short-circuits a resistor 7 to give maximum control-winding current and consequently maximum alternator field current. For a rectified voltage above the pick-up voltage for the switch the current is reduced to a minimum valve determined by the resistor 7 and the coil 9 is shunted by a resistor 14 so that the current in the coil 9 falls at a rate dependent upon the time constant of the resistor and the inductance of the coil. The switch oscillates at a rate determined by the rectifier voltage. In a modification, Fig. 2, the switch and time delay resistor 14 are replaced by a relaxation oscillator comprising a cold cathode valve 15, a resistor 16 and a capacitor 19. An alternating output of the oscillator is fed to the control winding 5 of the magnetic amplifier through a rectifier 18. The cold cathode valve may be replaced by a suitable transistor arrangement.

Title: Improvements in or relating to centrifugal pumps
IPC: F04D1/00
Filed: 1953-07-21
Abstract: 730,357. Centrifugal pumps. SCHELLENS, C. A. July 21, 1953, No. 20196/53. Class 110(1). A centrifugal pump comprises a casing member having a stepped bore with an annular shoulder therein, and a circular diaphragm closing the bore and pressed against the shoulder. The casing of the pump is bolted to the casing 12, Fig. 1, of the driving means and comprises a main part 20 closed at each end by end plates 22, 24. An inner portion 50 of the casing is integral with the main part 20 and contains a volute 52. It has a bore stepped to provide shoulders 60, 62 which are engaged by flanges 68, 70 of diaphragms 64, 66, respectively. A diffuser is located between the diaphragms and preferably comprises two separate annular parts 72, 74, the latter carrying diffuser vanes 76. A ring 90 is screwed into a threaded portion of the bore until, it abuts the diaphragm 64 and is then slightly backed off. Bolts 94 are then tightened up against the diaphragm 64 to force the flanges 68, 70 into fluid-tight abutment against the shoulders 60, 62, the thrust being transmitted through flanges 96, 98 of the diffuser. Since the flanges 96, 98 are radially offset, the thrust slightly distorts the diffuser, producing a spring effect which holds the diaphragm 66 against the shoulder 62. The relative dimensions of the parts of the pump are such that assembly can be effected by passing the various parts, including the bearing 35 and its retainer 36, through the outboard opening which s subsequently closed by the end plate 22. Fig. 4 shows a modification in which the diffuser has a flange 106 which is a radial force fit against a shoulder 110 to prevent leakage, while the thrust is transmitted through a flange which is provided with a series of radial slots 114 to communicate the liquid pressure within the passage 84 to the back of the. diffuser part. 102. The diffuser parts 100, 102 are thus clamped together, by the pressure prevailing in the passage 84, which is greater than that, within the diffuser.

Patent GB-213648-A (GB)
Abstract: 213,648. Clarke, T. Dec. 27, 1922. Switches, actuating.-Upon failure of one or more elements of a composite load, the consequent reduction of driving-torque causes an electric circuit to be opened or closed, whereby an alarm lamp is lighted or stop means are actuated. As applied to a rotary mixing-reel b, Fig. 1, to which, say, three grades of flour are fed through shoots p, q, r, the driving-pulley a is connected to its shaft g through the device shown in Fig. 3. When the reel b is dealing with the full quantity of flour, stops d, e, carried respectively by the pulley a and an arm f on the shaft g, come into contact against the action of a compression spring c, and a pair of electric contacts h, i, mounted on and insulated from the driving and driven members, are separated. When the supply of one or more ingredients becomes deficient, the spring c expands, as shown in Fig. 3, and closes the circuit through the contacts h, i, slip rings k, m. and brushes n, o to light a lamp or stop the feed of the remaining ingredients. Alternatively, the reduction of torque may separate the contacts h, i. The device may be applied to a worm conveyer feeding the final stream of flour to a silo. Specification 205,200 is referred to.
