Title: Lung ventilating apparatus
IPC: A61M16/20
Filed: 1975-09-19
Abstract: 1528583 Manually-operated lung ventilator R L HESSE 19 Sept 1975 [20 Sept 1974] 38635/75 Heading A5T A manually-operated lung ventilator comprises a self-expanding bladder 15 having an inlet 16 and an outlet opening 26, and a valve device comprising a valve housing 1 communicating via at least one port 2, and being adapted to be connected to the respiratory system of a patient, the valve device having a controlling means adapted to close the port(s) 2 when the pressure downstream of port(s) 2 exceeds ambient pressure by a predetermined value and to reopen this port when the excess pressure downstream of the port falls below the predetermined value or when pressure in the bladder is reduced. The controlling means comprises a valve disc 10 fixed to a stem 11 which passes through housing 1. The housing is divided into two chambers 1' and 6 by a movable air-tight partition wall 8 which is fixed to the stem 11. The valve disc 10 is biassed to an open position by a compression spring 14. On squeezing bladder 15 respiration gas passes through port(s) 2, chamber 1', stud 5 and to the patient. If there is a blockage in the patients system or if the pressure build-up is too fast then pressure in chamber 1' builds up until the bias of spring 14 and the ambient pressure in chamber 6, having a port 7 open to atmosphere, is overcome, partition wall 8 moves to the right and the valve disc closes port(s) 2. As respiration gas is further absorbed by the patient pressure in chamber 1' drops and the valve opens to provide the patient with more gas. When inhalation is complete the patient exhales through mask 18 via a three-way valve 17, the bladder being released by the operator. The next inhalation then commences. The predetermined value of excess pressure over ambient pressure is set by the choice of spring constant of spring 14. The end of the valve stem 11 acts as an indication to the operator of when the valve disc is closed i.e. that the flow rate to the patient is too high, and may also be used as a safety feature since the valve disc may be held open manually by pressing on the projecting end of stem 11. The valve housing is preferably made in two parts, i.e. the inlet part comprising the valve stem, spring, disc, partition wall and wall with port(s) 2 and the outlet part, comprising the stud 5 and the rear part of chamber 6, the two parts being readily parted.

Abstract: 927,009. Electrostatic coating. METAL BOX CO. OF SOUTH AFRICA Ltd. Oct. 30, 1961, No. 38753/61. Addition to 890,550. Class 117. [Also in Groups XV and XVII] A component of a sealable container, e.g. the end member 15 of a can, is coated internally with lacquer before a catalyst in powder form is applied electrostatically to the lacquer coating to which it adheres. The end members 15 are removed from a magazine 16 by claws 14 on an endless conveyer 10, the lacquer being applied at 19. The catalyst 24, in the form of finely divided palladium, is picked up on a drum 25. A high-voltage unit 27 applies a high potential between guide rails 18 and the drum 25 by way of the catalyst and its container. By operating a micro-switch 29, each end member 15 causes a grid 28 to receive an intermediate potential from the unit 27, thereby effecting a flow of powdered catalyst through the grid on to the lacquered member 15. The catalyst is dried at 21 and surplus powder brushed off at 22. In a modification, Figs. 4 and 5 (not shown), the end members are carried on a reciprocating conveyer or slide from which they are raised at intervals by lifting-mechanism. The catalyst is applied by means of a belt passing between two drums, the first of which rotates in a container for the catalyst. The application of lacquer and catalyst is effected from above as the end members are raised. The catalyst may be applied by means of a current of air or other gas.

Abstract: 1,162,384. Treating polyolefin materials. D. D. GAGLIARDI. 31 Aug., 1966, No. 38905/66. Heading D1P. The heat and light stability of a preformed article made from a solid polyolefin is im-. proved by imbuing its surface with a zinc, cadmium, chromium, cobalt, nickel, tin or zirconium salt of an organic substituted phosphoric compound having the formula in which R is a nalkyl, cycloalkyl, aryl, alkyloxy, cycloalkyloxy or aryloxy radical, R' is a monovalent radical which is a hydroxy, alkyl, cycloalkyl, aryl, alkyloxy, cycloalkyloxy or aryloxy radical and R" is a monovalent radical which is hydrogen or or R is a polyvalent radical joining two or more of the phosphate or phosphonate radicals, the radicals R, R' and R" when organic radicals preferably containing 2-20 carbon atoms and optionally being substituted with one or more fluorine, chlorine, bromine or iodine atoms. The metal salt may be applied to the surface of the article which is then heated to a temperature of at least 100‹C and at least 10‹C below the melting point of the. polyolefin for sufficient time to imbue the surface of the article with the applied compound. Instead of the metal salt itself, the free organic substituted phosphoric compound and a salt of the metal with a weak acid, i.e. an acid having a dissociation constant less than that of the organic substituted phosphoric compound used, e.g. acetic, citric or tartaric acid, may be applied to the surface of the article which is then heated. Alternatively the free organic substituted phosphoric compound may be applied to the surface of the article which is then heated and the article is then treated with a solution of the weak acid salt of the metal. The treating agents may be applied from aqueous or organic solvent solutions or dispersions and after drying the treated article may be heated by direct heating, by flash diffusion of the heating agent under pressure, or in the presence of superheated steam or steam distillation onto the surface. The treated articles may subsequently. be scoured, rinsed and dried and may also be treated with amino compounds, dyes, pigments, oil-repellents or antistatic agents. The articles treated may be in the form of fibres, yarns or fabrics. Fabrics comprising polyolefin fibres, e.g. fibres made from homo- or copolymers of ethylene, propylene or 4-methylpentene-1 in admixture with polyester, nylon, silk or cotton fibres may be treated.
