IPC: F04B45/053
Filed: 1917-10-23
Abstract: 111,105. Corblin, H. Nov. 7, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Compressed air and gas engines.-In a diaphragm pump for gases or liquids, applicable, as stated below, as an engine with expansion of compressed gas, a large sheetmetal diaphragm is adapted to be oscillated in a chamber enclosed by two dished plates, between which the edge of the diaphragm is held, and the valves are mounted in one of the plates and are flush with the surface with which the diaphragm makes close contact during discharge. As shown, a chamber d, Fig. 2, is formed by two conical recesses with a large common base and small height in plates a, b, which are bolted together at their edges and clamp between them the edges of a circular diaphragm c by means of squared recesses a<3> and rounded projections b<2>. The fluid enters the space above the diaphragm by a pipe a<1> and past a valve e, and is discharged past a valve f, both valves being spring-controlled and having their surfaces flush with the lower surface of the plate a. When the apparatus is used as a pump, the central part of the plate b is perforated at b<1> to admit an actuating-liquid to the lower surface of the diaphragm from a pipe g, Fig. 1, which connects the chamber d to a valveless or plunger pump h. The plunger of the pump h displaces a larger volume of liquid than is necessary to move the diaphragm between its extreme positions, and this is permitted by the provision of a liquid tank i connected as shown to the pipe g and provided with a valve i<2> opening at a predetermined pressure and a snifter valve i<1> opening at a predetermined vacuum, or with a cock suitably regulated to produce resistance to the discharge and suction of the liquid. The diaphragm may be other than circular; thus it may have the form of a flatsided oval or may be tubular to be oscillated between inner and outer rigid tubes recessed on their opposing surfaces. The diaphragm may also be corrugated &c. Several delivery valves may be employed forming a grating against which the diaphragm contacts. The diaphragm pumps may be used as engines with expansion of compressed gas in cases where lubrication is difficult, as in refrigerating-installations &c.

Title: Vented Fuel Element
IPC: G21C3/04
Filed: 1969-03-26
Abstract: 1,188,276. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 26 March, 1969 [24 July, 1968], No. 15836/69. Heading G6C. A vented fuel element comprises a cladding tube 11 containing in its lower end fuel pellets 12 and a ceramic pellet 13, its upper end being closed by an end plug 14 to form a gas plenum. A thin-walled plenum cup 16 is positioned in the plenum so as to form a leakage annulus 17 between it and the tube 11. The end plug 14 is provided with an aperture 18 through which a vent tube 19 extends into the cup 16, the tube 19 being secured to the end plug 14 by a weld 20 and terminating at its lower end immediately above the bottom of the cup 16. The upper end of vent tube 19 is initially sealed such as by a pinch-off weld 21. Nickel is a suitable material for the tube 19 since it may be cold welded, and in addition is very weak at the normal reactor outlet temperature (about 1100‹ F.), at which temperature it will easily rupture under a relatively low internal pressure to form the required vent. Alternatively, a soft solder may be used in which case the tube 19 can be of the same stainless steel as in the rest of the fuel element. A conventional "diving bell" type vent may be modified to provide the vent and seal arrangement of the present invention by welding an additional section of cladding tube to a transition member welded in position across the upper end of the fuel element, this additional section having an end plug and vent tube as in the embodiment described above. Instead of the plenum cup, however, a tube extends up through an aperture in the transition member to which it is welded and terminates immediately below the end plug.

Class 106 (1) In an electronic totalizer, digits are introduced into each decimal denomination in the form of pulses representing values " 1 " and " 5 " which are switched onto separate channels leading to a quinary and binary counter respectively by means controlled by timing or "pilot" impulses, the carry-over from the quinary counter being applied to the binary counter and the carryover from the latter being applied to the quinary counter of the next higher denomination. As shown, the quinary counter comprises three series-connected bistable trigger pairs A, B, C with associated indicating lamps 30 (e.g. as described in Specification 679,993). After four input pulses have been received from the zero position shown (upper valve of each trigger conducting), C will be switched over thereby applying an opening potential via line 9 to gate G, so that the next pulse will pass as a carry-over through the gate and rectifier 15 to the binary counter comprising a single trigger pair D and will also be fed back through rectifiers 31 (and a delay circuit if necessary) to reset A, B and C. Input digit pulse trains are applied at E1, pulses at the first four pulse instants, representing " 1 ", being pased through a gate G' to the quinary counter, and a pulse at the fifth instant, representing " 5 ", being passed through gate G" to counter D, the gates being controlled by a pilot impulse p at E2 applied from equally spaced tappings of a delay line R as shown. In modifications, the gates G', G<SP>11</SP> are controlled by a trigger pair having only one stable state, the pilot impulse switching it over to its unstable state for between four and five pulse periods, or by a series of equally spaced pulses from a distributor common to all denominations. A modified quinary counter also is described including a feed-back arrangement between trigger C and triggers A and B, the gate G being omitted.
