Title: Vented fuel system
IPC: G21C3/04
Filed: 1967-09-11
Abstract: 1,142,926. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 11 Sept., 1967 [8 May, 1967], No. 41378/67. Heading G6C. In a fuel element 10 having a fission product gas plenum 11, a fission product delay vent comprises an inner conduit 14 opening at one end into the plenum 11 and at the opposite end into a plenum 21 within a containment shroud 20 arranged concentric about and spaced apart from the conduit 14. The shroud 20 is welded to the lower portion of the conduit 14 and is provided with a number of ports 22 around its lower portion. Immediately above plenum 11, and in the lower portion of conduit 14, are disposed a number of planar, spaced-apart, porous members 15a-15g retained in place by indentations 17 in the conduit 14. In the upper portion of conduit 14 is a valve means comprising two planar, spaced - apart, impermeable members 18a, 18b retained in conduit 14 by indentations 19. These two members are arranged to fit tightly into conduit 14 so that the release of any gas will occur only between the peripheral edges of the members and the conduit wall when a predetermined pressure level is reached. The plenum 21 besides acting as a passage through which fission product gases leaving the valve means are guided to the exterior of the fuel element, serves to prevent coolant outside the fuel element from flowing into the vent and valve portions to clog or disturb their operations. The porous members 15a-15g preferably have a pore size ranging from 10 microns for member 15a to < 1 micron for member 15g. They are not brazed or welded to the wall of conduit 14 so that in the event of an overpressure transient, or a partial or complete plugging of a porous member, gases within plenum 11 are allowed to escape around the peripheral edges of the porous members. A fibrous material 26 may be disposed between the porous members 15a-15g and between the porous member 15g and the impermeable member 18a in order to provide a large surface area upon which solid fission products may be deposited. Suitable material is a random mesh of glass, quartz or stainless steel wool, or a woven mesh of stainless steel or Zr or Ti wire or glass or quartz filaments. The surface of the material may be coated with Ag or Cu or charcoal having traces of such metal as a gettering agent. A suitable material for the porous members 15a-15g is sintered, powdered stainless steel.

Title: Lift control circuit arrangement
IPC: B66B1/14
Filed: 1966-09-16
Abstract: 1,147,624. Lift control systems. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Sept., 1966 [22 Sept., 1965], No. 41412/66. Heading B8L. When a lift is at the sixth floor, so that contact r6-2 of a position-indicating relay is closed, and a landing call is registered at the third floor by closing relay-contact b3, a circuit is completed through diodes G15, G30, G29, to energize " down " relay D. Energization of the " up " relay U is prevented because blocking diodes G23-G20, are located between contacts b3 and r6-1. As the lift moves downwardly contact r6-2 is opened and contacts r5-2, r4-2, are successively closed and opened to maintain energization of the relay D until the lift approaches the third floor. The relay D is then de-energized because diode G31 blocks current through contact r3-2. The lift is braked to a standstill and contact b3 opens. Contact k4 is closed when a push-button inside the lift is actuated to call for movement to the fourth floor, the relay U being energized through diode G6 and contact r3-1. Energization of relay D through contact r3-2 is blocked by diode G30. When the lift approaches the fourth floor, contacts r3-1, r3-2 open and contacts r4-1 r4-2 close. The relay U is then deenergized due to the blocking effect of the diode G22. The diodes G17-G24 and G25-G32 are inserted in the circuits for the relays U, D respectively, whereby relay U is energized only when the lift is below a destination floor, and the relay D when the lift is above the respective destination floor. Rectifiers G1-G16 decouple the circuits controlling the relays U, D.

Inventor: LAWLEY HERBERT GEORGE
IPC: C07C7/152
Filed: 1960-12-01
Abstract: Mono-olefins (including cyclo-olefins) are separated from one another by selective formation or decomposition of complexes with a solution of a heavy metal fluoborate or fluosilicate. Selection between olefins may be made by (a) using a temperature at which only one component forms a complex, (b) by using a salt concentration which will effect the formation of only one complex, (c) using insufficient complex-forming salt for all olefins to form complexes or (d) dissolving all olefins and recovering separately by decomposition of the complexes in stages.  Complex formation occurs at - 40 DEG  to 40 DEG  C. and olefins are recovered by heating, preferably to not more than 60 DEG  C. and/or by reducing the pressure.  Reference is made to the use of salts of silver, copper, mercury and platinum; aqueous silver fluosilicate or fluoborate is preferred.  Olefins decrease in solubility in the order (R is alkyl) RCH=CH2> RCH=CHR > R2C=CH2 > R2C=CHR > R2C=CR2 and with increasing molecular weight. Other non-complex forming compounds may be present.

Title: Valved hose coupling
IPC: F16L29/04
Filed: 1960-12-06
Abstract: 923,455. Hose couplings. AEROQUIP A.G. Dec. 6, 1960 [Feb. 29, 1960], No. 42036/60. Class 99(1). A manually operable hose coupling comprises a pair of interconnectible valve assemblies, a first of the valve assemblies comprising a first valve body 10 having a bore 18 therein adapted to be put in communication with a source of pressurized fluid, a valve seat 24 adjacent one end of the bore, and a valve stem 34 mounted for axial movement within the bore and having at one end a valve head 36 engageable with the valve seat and at the other end a portion 64 in sealing relation with the bore, the area of that portion exposed to fluid pressure in the bore being larger than the opposed area of the valve head exposed to fluid pressure in the bore whereby such fluid pressure acting on the opposed areas causes a differential tending to maintain the valve head in engagement with the valve seat. There is manually-actuable means operatively associated with the valve stem for selectively axially positioning the stem. As shown, the body 10 has screwed therein a sleeve 22 provided with a valve seat 24 and a flange 26 engageable by a nut 28, the seat being engaged by a sealing ring 40 retained on the valve head 36 by a retainer 38. The stem 34 of the spring- loaded valve is supported by and projects through a cap 42 having a flange 48 abutted by a screwed ring 44 and securing the outer periphery of a flexible diaphragm 60 the inner periphery of which is sealed to the valve stem 34 by a ring 58 held in position by a screwed sleeve 54. A finger-actuated lever 70 is pivoted via a handle portion of the body and contacts the projection 52 of the valve stem. The coupling part 82 includes a spring-loaded valve having a valve head provided with a resilient seal 110 held in place by a retainer 108 and for engagement with a valve seat 98. Radial fluid ports 100 are provided. In coupling, the sleeve 22 is received in the tapered bore of the part 82 and to bring the retainers 38, 108 into abutment and the nut 28 is screwed on to the coupling part 82 to complete the connection. Movement of the lever 70 shifts the stem 34 to open the two valves, a projection on the lever being positioned in slots in the handle to maintain the valve in the partial or fully open position. The pressure of the valve springs is augmented by the pressure fluid to hold the valves on to the valve seats. An 0-ring may be employed in place of the diaphram 60.

IPC: H03M1/00
Filed: 1966-09-23
Abstract: 1,103,647. Digital to analogue converters. STANDARD TELEPHONES & CABLES Ltd. 23 Sept., 1966, No. 42493/66. Heading G4H. In a decoder, e.g. for a PCM system, a logic circuit 1 receives a digital coded signal in serial form and controls a digital-to-analogue converter 2 to produce analogue signals of a single polarity, which are applied in true and inverted form to switches 5 and 6 having a common output point 11 connected, via a capacitor 12, to a high-impedance output amplifier 14, the capacitor being connected to earth by a third switch. The capacitor 12 and switch 15 compensate for the " offset " voltages of the switches 5 and 6. These are electronic switches and the offset voltage may be regarded as a battery in series with an ideal switch. When the capacitor is earthed on the remote side it is charged to the value of the offset voltage but in a direction opposite to the offset voltage. When converter 3 produces its output signal, this and the offset voltage are applied to the capacitor. The charge on the capacitor cancels the offset voltage, leaving the correct analogue equivalent of the digital input. The sign of the sample value is given by the first digit. This digit appears on the first output terminal when the coded signal is read into the control logic 1 and is used to select one of the switches. The switch 15 is then briefly closed so that the offset voltage of the selected switch is applied to the capacitor 12. A timing signal controls switch 15. The characteristic of the converter is non-linear to improve the quality of transmitted speech signals.

Title: Removing oil from water with sulphur
IPC: C02F1/68
Filed: 1971-09-15
Abstract: 1340369 Removing oil from water AMOCO PRODUCTION CO 15 Sept 1971 [13 Oct 1970] 43075/71 Headings C1A and C1C [Also in Divisions B1 and B2] In an apparatus or process for removing oil from water the oil is caused to coagulate or coalesce by contacting it with sulphur in the solid phase (e.g. yellow sulphur). The process may use sand (e.g. of grain size 0À5-8 mm.) coated with sulphur. The sulphur coating may have a thickness of 0À1-3 mm. In the embodiment of Fig. 1 the apparatus comprises a vessel 10 having a gravel bed 22 supporting a bed 24 of sulphur coated sand, a baffle plate 21, oily water inlet 12, water outlet 16 and oil outlet 14. The flows of liquid through inlet 12 and outlets 14, 16 may be automatically controlled. The embodiment of Fig. 1 may be modified to discharge oil and water through the same outlet to a skimming tank. In another embodiment (Fig. 5, not shown) the oily water is passed downwardly through three successive beds in a tank and discharged to a skimming tank. The top bed may comprise yellow sulphur, sulphur coated sand or coal; the intermediate bed, sulphur or sulphur coated sand; and the bottom bed, gravel. In Fig. 4 oily water from line 88 together with a slurry of sulphur from line 90 and wetting agents if desired, is introduced to a cyclone separator 80 (or rotary vacuum filter). Purified water is discharged through outlet 84 and sulphur with coalesced oil is passed to heated vessel 94. The oil is discharged through line 96. The sulphur is discharged through line 100 to vessel 104 where it is mixed with water to form a slurry to be used in treating more oily water. In another embodiment the oily water may be passed through a filter cartridge (Fig. 6, not shown) comprising a hollow fibrous (e.g. wool, cotton, plastics) cylinder carrying sulphur. The openings through the cylinder wall may decrease in size towards the inner surface of the wall. In the apparatus of Fig. 3 for producing coated sand particles the sand and sulphur are passed by a screw conveyer through a heating section 68 which melts the sulphur to coat the sand and the coated sand is then cooled by air blast 70 (or by a cooling coil, not shown) which with the aid of beater 72 also breaks up any clumps of coated sand.

[Also in Division B1] Capillary columns for gas chromatography are made by drawing a metallic tube over a plug through a drawing nozzle to give a capillary tube, a mixture of lubricant and granular partitioning agent or support material being introduced into the larger open end of the tube, the effect of drawing being such that the partitioning agent or support material is embedded in the inner surface of the capillary tube. In a specific embodiment, as shown, a low viscosity lubricant 20 carrying the partitioning agent or support material is introduced into the open end of the large diameter tube 13. The tube is drawn over the plug 15 and through the die 10 to give a capillary column 13<SP>1</SP> having material embedded in its surface 21. The cone angle 17 of the plug is smaller than the cone angle 11 of the bore, so the annular channel 19 narrows in the direction of drawing. The lubricant may be removed after drawing, e.g. by evaporation or washing.

Title: Oxygen-air diluter
IPC: A61M16/12
Filed: 1973-09-18
Abstract: 1440256 Respiratory apparatus ROBERTSHAW CONTROLS CO 18 Sept 1973 [19 Sept 1972] 43749/73 Heading A5T An oxygen-air diluter for respiratory apparatus comprises a casing 10, ambient air inlet 14 connected by conduit 58 to outlet 16, and a chamber 34 separated into an outlet pressure sensing portion and a reference pressure sensing portion by diaphragm 38 which causes valve 26 to regulate the flow of oxygen from inlet 12 to outlet 16, the pressure in the reference pressure sensing portion being controlled by valves 72 and 86 causing such portion to be vented to atmosphere or-connected to the oxygen inlet. At a low altitude and with a manually-operable lever 88 at its dilute mode position, suction by the user at outlet 16 causes diaphragm 38 to push paddle 36 thereby opening orifice 32. Oxygen passes from the top side of the diaphragm 28 faster than it can be replenished through passage 30 and so diaphragm 28 lifts valve member 26 allowing a small amount of oxygen to pass from inlet 12 to outlet 16 to supplement air drawn through air inlet 14. When suction ceases equal oxygen pressure reestablishes itself on each side of diaphragm 28 via passage 30 and since the top side is of greater area than the bottom side, diaphragm 28 moves downwards whereby valve member 26 cuts off the oxygen flow. As the altitude increases, aneroid bellows 64 expand to progressively close valve 68 reducing the air supply and pushes rod 92 to open valve 72. Oxygen then passes faster from orifice 78 than it can be replenished through restriction 108 so that spring 100 closes valve member 86 against seat 102 and the oxygen inlet pressure presses diaphragm 38 downwards, this pressure being limited by valve 42. With increasing altitude the bellows 64 become fully expanded and 100% oxygen is supplied to the user on demand. As the altitude further increases, aneroid bellows 50 expand and contact valve 42 to restrict its opening, this causes 100% oxygen to be supplied at pressure to outlet 16. Should the oxygen inlet pressure decrease sufficiently, spring 122 acts on piston 116 to progressively close valve 114. Valve 62 exhausts excess outlet pressure. Turning lever 88 to its 100% oxygen mode position opens valve 72 causing 100% oxygen to be supplied at pressure to outlet 16.
