Title: Fluid separation apparatus
IPC: B01D47/14
Filed: 1965-12-31
Abstract: 1,143,400. Fluid-separating laminates. DORR-OLIVER Inc. 31 Dec., 1965 [4 Jan., 1965], No. 55356/65. Heading B5N. [Also in Division B1] A fluid separation unit comprises a plurality of spaced apart laminates 20 each consisting of a fluid-conducting support lamina 22 with selectively-permeable membranes 24 on its surfaces, a partition 70 being sealed between adjacent terminal edges of the laminates to form a portion of a closed conduit 30 to circulate feed fluid between the laminates and to define an effluent space 75 external to them, the fluidconducting support laminae 22 extending through this partition to communicate with the effluent space. The spaced-apart laminates may be separated by corrugated spacers, e.g. of plastics or metal or, as shown, alternate laminates may be corrugated to act as spacers or they may all be corrugated and assembled crest-to-crest. A cylindrically shaped stack of laminates may be assembled with partition, to form a cartridge 44 and fitted into a housing 42 with sealing rings 76 and screen 58. Feed fluid entering through inlet 52 passes up through the inter-laminate spaces, the effluent permeating the membranes 24 and passing along the interconnected interstices of the support laminae 22 and into the effluent space 75 whence it emerges from the outlet 54. The support laminae may be of resin treated paper, resinbonded glass fibre or plastics fibre mat, resinbonded granular solids, open-foamed plastics or sintered plastics, the preferred example being of a phenolic resin-treated filter paper. The selectively-permeable membranes may be of regenerated cellulose, cellulose acetate, or polyelectrolytes. They may be applied to the support sheets by adhesive; by casting and applying before they have dried; by casting directly, or by temporarily bonding by means of a liquid film until they have been assembled to form a cartridge. The top and bottom edges of the support laminµ are rounded and the outer laminµ envelop them to form a closure. The partition wall may be of plastics centrifugally cast into the spaces between laminates.

In apparatus for assisting respira- ' tion, gas is supplied during inhalation and cut off during exhalation by a supply valve 5 controlled by a diaphragm 16 in response to pressures in a duct 12 which supplies gas to the patient, the diaphragm being separated from the duct by a partition wall 16a having a non-return valve 14 which opens for a short period when "the patient commences to inhale, so that the diaphragm is exposed to a reduced pressure and opens the supply valve 5, and a valve 17 controlled by a second diaphragm 21 to open vNhen a predetermined positive pressure is .reached-in in the duct, so that"the diaphragm-is exposed to the positive pressure and:closes the supply valve 5. When the supply valve 5 is opened gas flows from a supply 1 through a valve -7 to a mouthpiece 8, by way of an ejector 35 having an air inlet valve 36 and the gas conduit 12 and also by way of an atomiser 33. Supply gas also flows to the control chambers of the valve 7 and a vent valve 27 for the duct 12 thus closing the valve 27 during the inhalation phase. When the valve 17 opens in response to a predetermined rise in pressure in the gas conduit, the diaphragm 16 moves to close the supply valve 5 thus terminating the inhalation phase. The conduit 12 is then vented to atmosphere through the valve; 27 so that the second diaphragm 21 closes the valve 17 and the patient is allowed to exhale naturally to atmosphere through a combined inhalation and exhalation valve 10.

Filed: 1968-12-10
Abstract: 1275560 Protective arrangements ENGLISH ELECTRIC CO Ltd 10 Dec 1969 [10 Dec 1968] 58554/68 Heading H2K A phase selecting arrangement, e.g. for a distance protective system, comprises means 3 ... 5 for deriving quantities, e.g. the line-toline currents, of a protected polyphase system, bridge circuits 6 ... 8 for producing signals indicative of the differences between the vector value of the quantities before and during a fault, comparators 17 ... 19 providing outputs when these signals exceed a predetermined limit, and means for establishing a pattern of binary signals identifying any type of fault. As shown, line currents of two respective lines are mixed in the transactors 3 ... 5 to derive the line-to-line currents and each bridge circuit 6 ... 8 includes a parallel resonant circuit with a variable capacitor C automatically adjusted by a frequency control circuit 11 ... 13. The outputs from the bridge circuits are rectified at 14 ... 16 and are compared in the comparators 17 ... 18 with a signal normally representative of 85% of the maximum of these outputs obtained through a diode circuit 20. The outputs from the comparators 17 ... 19, being short duration binary signal, are stored by a memory circuit 29 which feeds a selector 31. This selector 31 has seven outputs, each for operating a respective switch 32 in dependence on the pattern of the binary signals, the selected switch 32 being operable to switch a measuring unit to the faulty phase(s). Contacts 33 of the measuring unit are connected in a holding line 55 for the memory circuit 29, this holding line being associated with various monitoring devices which "seal-in" the memory circuit in the event of a line-to-line fault or to permit a fresh selection when a line-to-earth fault evolves into a line-to-line fault or a three phase fault, while preventing false selection due to load changes. To prevent incorrect operation when current transformers saturate, an over-current "override" circuit is provided and comprises auxiliary current transformers 43 ... 45, rectified circuits 46 ... 48, comparators 50 ... 52, a reference source 53 and a logic circuit 54 operative to change over the contacts or one of switches 26 ... 28 when any two outputs from the comparators are high. The memory circuit 29 then receives an input from the circuit 54 and phase selection is obtained. The rectifier circuits may be similar to the circuit described in Specification 1,162,206.

Title: Fireproof Cellulosic Fibres
IPC: D06M11/79
Filed: 1979-04-18
Abstract: Unfelted and unbroken waste cellulose fibers are individually clad with a non-flammable, finely divided and inexpensive inorganic material that is insoluble in water, preferably clay. The fibers are dampened with enough water to weaken the interfiber bonds, which are disengaged without breaking the fibers, and the unfelted fibres are mixed intimately with finely divided clay dispersed in the water. Surface tension of the water holds the clay on the damp fibers; and as the clad fibers are dried, the clay bonds securely to the fibers by hydrogen bonding to make them fire resistant. Sodium silicate is preferably coated on the clad fibers during the mixing step to improve the fire resistance in low density products. The clad fibers are preferably mixed with air before drying and can be formed into a resilient bat useful as insulation.
