Title: Improvements in or relating to fluid flow meters
Inventor: WOLFF HEINZ SIEGFRIED
IPC: A61B5/087
Filed: 1953-12-31
Abstract: 807,152. Electric indicating systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 31, 1955 [Dec. 31, 1953], No. 36338/53. Class 40 (1). [Also in Group XXIX] A fluid-flow meter particularly adapted for measuring the air expired by a human being comprises a chamber 1 with an inlet 2 and an outlet 3 constituted by a re-entrant tubular member 6, the member 6 co-operating with a diaphragm 5 which together with an annular flexible member 4 constitutes one wall of the chamber to form a variable annular outlet port. Leaf-springs 7 urge the diaphragm 5 towards tube 6, so that its position indicates the rate of fluid flow; this position is sensed by a contact 11 moving along a potentiometer 12 in an electrical bridge circuit to produce a voltage, corresponding to the fluid-flow, which may be integrated to give total flow over a period of time, or recorded. Weights 9 are so disposed on the springs 7 as to compensate for the weight of the diaphragm so that the device may be used in any angular position; non- linearity of the springs 7 may be compensated for by a restriction at the lower end of tube 6. In a modification, the rigid tubular member 6 may be replaced by a coil spring secured to the diaphragm and to the outlet in the lower face of the chamber so that in the no-flow condition its convolutions abut to form a tube, but under the action of fluid flow separate to form a helical outlet port.

Filed: 1976-09-03
Abstract: 1535988 Drafted needled non-woven fabric PHILLIPS PETROLEUM CO 3 Sept 1976 [5 Sept 1975] 36637/76 Heading D1R A non-woven fabric is produced by forming a fibrous batt 36, drafting the batt with a first warp drafting means 40, needling the drafted batt with loom 58, drafting the needled batt in a second warp drafting zone 62 and drafting the warp-drafted needled batt in a fill drafting zone 72. Preferably the fill drafted batt is heated whilst tensioned in the fill direction to produce autogeneous bonding. Heated fluid or heated rollers may be used but infra red radiators 80, 82 are preferred because deformation of the fibres cross-sections is avoided and the depth of bonding is controlled. With irradiation from one side only the batt may be bonded substantially through to the other side whilst leaving a nap on the other side of the batt. Lamination to a vinylic polymer film is thereby facilitated. Irradiation from both sides produced uniform bonding. Polypropylene, polyethylene terephthalate or polycoralactam fibres or a blend thereof and/ or with natural fibres, the fibres having a denier of 1 to 20 and a length of 1.5 to 10 inches may be carded, cross-lapped, recarded and recross-lapped and deposited on belt 36 to provide a batt of fibres orientated preferentially in the fill direction. A second such batt is superimposed and the combined batts fed by aprons 42 to sets of drafting rolls 44-52, needled at 58, stretched in the warp direction by rolls 64, 66, stretched in the fill direction or stenter frame 72 and heat bonded. Draft ratios and punching densities are specified.

Title: Improved manufacture of dyestuff pastes
IPC: D06P1/645
Filed: 1932-12-30
Abstract: Acetate silk dyes of the group defined below are converted into dyestuff pastes suitable for the preparation of printing colours by subjecting the dyes to prolonged trituration or grinding in a grating machine or grinding mill with a water-soluble viscous organic liquid of the group consisting of water-soluble liquid polyhydric alcohols and alkyl ethers thereof, thioalkyleneglycols and alkylol amines, in proportion insufficient to dissolve the quantity of dyestuff used, until there is produced a homogeneous paste in which the dyestuff particles are finely dispersed and do not settle during storage, the said triturating or grinding operation being carried out in the presence of water or with subsequent addition of water.  The acetate silk dyes which may be so treated comprise dyes of the anthraquinone-, azo-, indophenol-or basic series containing at least one primary, secondary or tertiary amino group which are insoluble in water and have affinity for acetate silk; vat- and sulphur-dyes are not included.  For the grinding or triturating operation ball mills, tube mills, colloid mills, disintegrators are mentioned, completion of the operation being determined by examining prints produced from samples of the paste until no increase in intensity is observed; generally 6--12 hours is required.  Liquids specified are glycerine, polyglycerine, glycol, polyglycol, butyleneglycol, glycol monalkyl ethers, ethylenethiohydrin, diethanolamine, triethanolamine and mixtures of these.  In examples: (1) diaminoanthrarufin or 1,4-dioxyethylamino-5,8-dioxyanthraquinone in the form of aqueous pastes are ground in a grinding mill with glycerine or triethanolamine for 24--48 hours; (2) the azo dye 2,4-dinitraniline --> m-aminoformanilide is ground in a grinding mill with aqueous triethanolamine; (3) the azo-dye 3-nitraniline --> N-methyl-4-oxyquinoline is ground in a grinding mill for several hours with aqueous glycerine; (4) 1,4-diaminoanthraquinone and 1,4-diamino-5-nitroanthraquinone are ground in aqueous glycerine in a grinding mill for 20--30 hours.
