Title: Liquid administration apparatus
IPC: A61M5/152
Filed: 1972-09-13
Abstract: 1398628 Intravenous apparatus BESTNU ENG PTY LTD 13 Sept 1972 [28 Sept 1971] 42419/72 Heading A5R [Also in Divisions Fl and F2] Apparatus for applying external pressure to a pliant bag 56 containing a liquid for administration to a patient comprises two pads having mutually confronting spaced-apart pressure-applying faces and loading means operable to cause relative mutual approach of said faces so applying pressure to the bag which is positioned between the two said faces. The two pads are constituted one by the rear wall 28 and the inflatable bag 29 which extends the full width and height of the rear wall and the other by a plate 52 adhered to a door panel 54 so that its side and bottom edges form steps 55 relative to the rear face of the door 54. Inflating the bag 29 causes the pressure--applying face 60 to move towards the pressure-applying face of the plate 52 and the steps 55 ensure that the pliant bag 56 is never completely flattened whereby any gas in the bag stays in the bag and is not administered to the patient. The pliant bag 56 is supported between these two faces by a pin 57 the outlet of the bag 58 being lowermost. The inflatable bag 29 has an inlet/outlet pipe 30, the air for inflating the bag being supplied by a manually operable air pump 10, via the pipe 41 and a valve (11) (Figures 3, 4 and 5, not shown). This valve, operated by the switch 50 in one position allows air to escape from the bag 29 so deflating it, in a second position closes the system to the atmosphere for allowing inflation of the bag and has a third position for allowing bleed escaping of air from the bag during inflation so permitting fine adjustment. The pressure of the air in the bag is shown on the dial portion 14 of a pressure guage 12 which is connected via the valve (11) to the inflatable bag. When the inflatable bag 29 is fully inflated and the two sides of the pliant bag 56 are pressed together there is still sufficient volume in the pliant bag to contain any gas that may have been included with the liquid due to ducts in the bag formed around the edges of the plate 52 which have not been compressed. There is a lateral duct 62 extending along the base of the pliant bag and a vertical duct extending the full height of the pliant bag, this ensures that any gas in the bag may proceed without obstruction to'the gas space above the liquid surface of the bag. The apparatus is housed in a small cabinet having an upper compartment 8 housing the valve (11), the pump 10 and the pressure guage 12 and a lower compartment 9 housing the two pads and the support for the pliant bag and having a door 21 on the front of this lower compartment for easy insertion of the pliant bags. A bracket 15 at the side of the cabinet provides for mounting the apparatus on a bed post (20) etc.

Title: Recovery of alkali metal salts of aromatic carboxylic acids
IPC: C07C51/42
Filed: 1972-09-13
Abstract: 1389130 Recovery of alkali metal salts of aromatic carboxylic acids PHILLIPS PETROLEUM CO 13 Sept 1972 42567/72 Heading C2C A process for the recovery of solid alkali metal salts of aromatic carboxylic acids from aqueous solutions containing them comprises mixing the aqueous solution with an organic liquid dispersant which is chemically inert with respect to said salt and in which said salt is substantially insoluble, said organic liquid further being substantially immiscible with water and having a boiling point higher than that of water, and heating the mixture thereby to remove by evaporation substantially all of the water contained in said mixture and to provide a slurry of the salt in said organic solvent. Examples of the organic dispersant are biphenyl, terphenyls, quaterphenyls, pentaphenyls and heavier polyphenyls, binaphthyls, naphthalene, anthracene, phenanthnene, pyrene, triphenylene, chrysene, perylene, pentacenyl and mixtures thereof. If is desirable that the organic dispersant should remain in the liquid state throughout the process; thus the compound should have a melting point below about 150‹ C. It is also desirable that the dispersant has a relatively high boiling point, e.g. above about 250‹ C. in order to aid in maintaining the pressure at a low level. The dispersant is preferably used in an amount sufficient to provide a dispersant: salt weight ratio in the range 0À3 : 1 to 5À0 : 1. The water removal step is conveniently conducted at a temperature in the range of 149‹ to 260‹ C. and at a pressure in the range of 80 to 800 p.s.i.a. The salt solution may be the product of a metathesis reaction between the aromatic carboxylic acid corresponding to said salt and the alkali metal salt of another aromatic carboxylic acid.

Abstract: 1,199,165. Tobacco-smoke filters. CELANESE CORP. 21 Sept., 1967 [21 Sept., 1966], No. 42908/67. Heading A2C. [Also in Divisions B1, B5 and D1] Tobacco smoke filters are made by spray spinning continuous filamentary material on to a moving surface to collect a continuous band of randomly arranged filaments, then laterally displacing portions of the band relative to each other so as to form an endless rod and severing the rod into separate lengths. The filamentary polymer may be polyethylene, polypropylene, polyamide, polyester, polyacetal or cellulose acetate. The filament diameter may have a minimum of 10-20Á and a maximum of 50-60Á with the mean being less than midway between the min. and max., and a periodicity of variations in diameter being at least several inches. The filaments may have a round, oval or trilobal cross-section. The band may be formed whilst the surface of the filamentary material is still tacky so that self-bonding of the filaments occurs. The collection surface may be electrostatically charged. The band may have a denier of 40,000-60,000. The band can be slit to form a plurality of rods. The rod may have a denier of 20,000- 100,000. A heat-activatable binder or a plasticizer can be applied to the band and activated after formation of the rod. The binder may have a m.p. of from 60‹C. up to the m.p. of the filament, e.g. a polymer of vinyl acetate, an acrylate ester, a vinyl ether, ethylene or styrene-butadiene copolymer. The binder can be applied as an emulsion or powder and may include compositions, or the binder itself may be used for removing phenol and/or toluene from the smoke stream, activated carbon, menthol. The plasticizer may be acetyl triethyl citrate, methylphthalyl ethyl glycolate, tributyl phthalate, tripropionin and triacetin. The filter may be encased in a paper wrapper, or may be treated with plasticizer and heated between rolls to form a hard outer sheath of coalesced filaments.

Filed: 1959-12-18
Abstract: 935,587. Cathode-ray oscilloscopes. SOC. NOUVELLE D'ELECTRONIQUE S.a.r.L. Dec. 18, 1959 [Dec. 29, 1958], No. 43152/59. Class 40 (7). In apparatus providing a cathode-ray tube display of a set of parallel marker lines P1 . . . Pn, the lines are produced by a " staircase " waveform 2e applied to the X deflect,on members and a saw-tooth waveform 2f applied to the Y deflection members, and the line intervals IN, their inclination a and the drift speed of the set, are adjustable. The markers are produced in the intervals between the scans of an unspecified picture display. At the beginning of each inter-scan period, a pulse is initiated by unit 1 and an ensuing saw-tooth pulse 2b from unit 2 is compared in unit 3 with a saw-tooth of very long duration from unit 5 to form a pulse c<SP>1</SP>, Fig. 2 (c), which triggers bi-stable multivibrator 6 to actuate a high-frequency saw-tooth generator 7, Fig. 2 (d), applied to the Y plates or deflection coils. The pulse from unit 1 triggers bi-stable multivibrator 8 to actuate saw-tooth generator 9, Fig. 2 (a), the output from which is fed, together with sawtooth waveform Fig. 2 (d), to form staircase waveform, Fig. 2 (e). The latter is fed through an adjustable-gain amplifier 11 to a unit 15 wherein mixing with an adjustable output from unit 14 produces the input of the X plates or coil. The drift speed is controlled by unit 5, which determines the delay of pulse c<SP>1</SP> relative to the start of the inter-scan period, Figs. 2 (g), (h), (i) (none shown), the marker line tilt by unit 14, and the inter-line spacing by the gain of amplifier 11. Multivibrators 6, 8 are re-set by the output of a comparator 12 wherein an adjustable D.C. voltage determines the number of lines displayed.

Title: Power driver devices suitable for driving fasteners
IPC: B25C1/04
Filed: 1973-09-14
Abstract: 1426378 Fastener driving tools ILLINOIS TOOL WORKS Inc 14 Sept 1973 [22 Dec 1972] 43362/73 Heading B4C A device for driving fasteners comprises a drive piston 30 operable within a bore 14, an accumulator piston 26 biased downwardly by, for example, a charge of gas and subjected to hydraulic pressure of the power fluid within the bore 14, and a seat 54 which makes a seal with the drive piston when this is moved upwardly by, for example, hydraulic pressure supplied through a line 200 and which is provided with a through-passage 53 and a relief valve 101, the arrangement being such that when the power fluid is supplied through a line 202 to the bore 14 via a passage 208 and port 204 to compress the accumulator piston the relief valve opens at a predetermined pressure to permit the power fluid to break the seal between the drive piston and seat and act on the full area of the drive piston with the aid of the pressure stored in the accumulator. After a driving operation on the fastener 300 shown, the hydraulic oil pump is switched to pass low pressure oil through the line 200 and through passages in a shock-absorbing member 80 to cause a brake spool 60 to carry the drive piston 30 up to its cocked position in sealing contact with the seat 54. In this cocked position the next fastener in a collated strip is indexed by low pressure oil in the line 211 pressing a piston 218 of a carriage 224 to the left against the action of a spring 220. When the trigger 12 in the handle 116 is pulled to fire a fastener, the hydraulic oil pump is switched to pass high pressure oil through the line 202 to cause the return of the brake spool to its lower position and to cause the accumulator piston 26 to compress an initial charge of gas at, for example, 2000 p.s.i. to, for example, 4000 p.s.i. When the upper pressure is reached, the relief valve 101 in the seat opens and the high pressure oil passes to the surface 38 of the piston to separate the piston from the seat and permit the oil to act on the full area of the piston, the force being maintained by the pressure of the gas in the accumulator. The drive piston is cushioned as its head 36 enters the taper in the brake spool and the oil under the brake spool is dispersed through passages in the member 80. A ball valve 56 in the seat relieves trapped oil when the piston is brought into contact with the seat. In a second embodiment, Figs. 10 and 11 (not shown), the seat extends through the accumulator piston chamber and serves as a guide for the accumulator piston (26a) which is annular in shape. Also in this embodiment the piston is provided with a counterbore (131) to reduce weight. In an alternative construction of a brake spool, Fig. 9 (not shown), the tapered bore is stepped to modify the cushion action and passages 73 allow circulation of oil for cooling purposes when the brake spool is in its upper cocked position.

Abstract: 1,129,879. Transistor frequency changing circuits; radio receiving circuits. HAZELTINE CORP. 25 Sept., 1967 [5 Oct., 1966], No. 43410/67. Headings H3Q and H3T. In a transistor frequency changer operative on U.H.F. and V.H.F. bands, the U.H.F. signals are applied to the emitter via capacitor 26 and the V.H.F. signals to the base, over capacitor 27. The U.H.F. local oscillations are applied to the emitter via capacitor 20 and the V.H.F. oscillations to the base, over capacitor 21. The intermediate frequency, which is just below the V.H.F. band, appears at the collector terminal 18. Series L.C. circuit 24, 25 is made resonant at the I.F. and so is low impedance over the V.H.F. band and high impedance over the U.H.F. band, while capacitor 22 effectively earths the emitter for U.H.F. but is of such a value that V.H.F. signals and local oscillations are developed on the base.
