Title: Regulation of respirators
IPC: A61M16/20
Filed: 1974-08-16
Abstract: 1459150 Artificial respirators F HOFFMANN LA ROCHE & CO AG 16 Aug 1974 [7 Sept 1973] 36250/74 Heading A5T A regulator for regulating the flow and pressure of respiration gas in a respirator having a flow measuring apparatus 36 and a pressure measuring apparatus 37 arranged in the vicinity of a patient connection and providing electrical signals indicative of the measured flow and pressure values, and a control valve 34 between a pump 31, for providing respiration gas, and said measuring apparatus, includes an electronic circuit for calculating nominal values of the flow and pressure at a given time from the actual values measured at said time and from fixed values, circuits for comparing the nominal values with the actual values and a control circuit which provides a control signal for adjusting the valve. The inspiration portion of each respiration cycle is divided into two phases, the first being pressure-regulated and the second flowregulated. The circuit for calculating the nominal value for the pressure during said first phase includes a ramp generator 46 and a delay unit 49 which provides an initial flattened portion on the pressure curve for the respiration cycle. The delay unit may however be bypassed for assisted respiration only Switching, effected by a logic circuit 57, from pressure to flow regulation occurs at a time t x  when the volume to be delivered on the basis of the provided flow curve during the second phase from said time to zero flow is equal to the difference between the nominal volume per respiration cycle and the volume inspirated at time t x . A comparator circuit 58 compares the nominal inspiration volume per cycle with the expired volume, per cycle averaged over six cycles, the nominal volume being correspondingly corrected for the next six cycles and, in the event of a difference exceeding 20%, produces a signal to activate an alarm 87. A further alarm 88 is operated to indicate congestion of the patients respiratory paths when the signal from circuit 58 is applied and, simultaneously, the nominal volume is not attained at the end of inspiration. The calculated expired volume per minute and the measured final inspiration pressure are displayed, as in the temporal ratio of pressure to volume control during inspiration, which ratio is adjustable between 1:1 and 1:3. The respiration is momentarily interrupted when the patient coughs, and the patient may, in assisted respiration, increase the volume per inspiration or the respiration frequency. The pump 31 is provided with a mixing valve 32 and a unit 33 for air humidification and temperature regulation. The function of the electronics and that of the pump are monitored and alarms operated in the event of malfunctioning. An external gas source may replace the pump.

Title: Improvements in or relating to terminally reactive polymers
IPC: C08F4/12
Filed: 1959-10-27
Abstract: Terminally reactive polymers are made by contacting a monomer system comprising at least one polymerizable vinylidene compound with an organo-lithium initiator under polymerization conditions to form a polymer containing terminal lithium atoms, and then reacting the polymer with at least one reagent to replace the lithium atoms with reactive groups.  Polymerizable compounds specified are butadiene, isoprene, piperylene, methyl pentadiene, 2-methylbutadiene, phenylbutadiene, dimethylhexadiene, diethyloctadiene, chloroprene, fluoroprene styrene, alkyl styrenes, p-methoxy styrene, vinyl naphthalene, vinyl pyridines and quinolines and alkyl derivatives thereof, divinyl pyridines and alkyl pyridines, alkyl esters of acrylic and methacrylic acids, vinyl and vinylidene chlorides, vinyl furan, vinyl carbazole, vinyl acetylene and vinyl methyl ethers. More than one monomer may be used to produce copolymers or block polymers, in the latter instance by the process of Specification 895,980.  The organo-lithium initiators preferably contain 2 or more lithium atoms, preferred being 1,4 - dilithiobutane, 1,2 - dilithio - 1,2 - diphenyl-ethane and adducts of lithium with naphthalene and biphenyl; other organo-lithium adducts are listed.  Polymerization is preferably carried out in the presence of a diluent such as benzene, toluene, cyclohexane, methylcyclohexane xylene, n-butane, n-hexane, n-heptane and isooctane.  The resulting polymers are treated with reagents to produce terminal reactive groups, representative treatments being with: (1) oxygen followed by sulphuric acid to produce terminal hydroxyl groups, (2) carbon dioxide followed by hydrochloric acid to produce terminal carboxyl groups, (3) cyanogen chloride to produce terminal cyano groups, (4) dimethyl formamide followed by water to produce terminal aldehyde groups, (5) acetyl chloride to produce terminal acetyl groups, (6) phosgene to produce chlorcarbonyl terminal groups, (7) chlorine to produce chloro end groups and (8) sulphur to produce terminal mercapto groups.  Other reagents which may be used to displace terminal lithium atoms are sulphur, ketones, acid halides, esters, amides, nitriles, isocyanides, isocyanates, quinones and ketenes.  The terminally reactive polymers may be further reacted with polyfunctional coupling agents such as polyhydric alcohols, polybasic acids and their anhydrides, halogen-containing compounds, diamines, diisocyanates, diepoxides and disulphonic acids, thereby producing coupled polymers in which the coupled polymer molecules may be the same or different. The examples describe the preparation of polybutadienes and polystyrenes which are reacted to produce terminal mercapto, hydroxyl or carboxyl groups and are then further treated by heating or by reaction with dichloro-p-xylene, tolylene diisocyanate or an epoxy resin.  Specification 817,693 also is referred to.

[Also in Division C7] In a storage matrix in which each storage element is formed by the intersection of channel section magnetic strips 1, 2, Fig. 1, each containing one or more conductors, at least one of the two strips comprises a layer of magnetic material on a grooved metallic and non-magnetic substrate. As shown in Fig. 2, a layer of magnetic storage material 1 is deposited in grooves of a glass substrate 3 to form one co-ordinate set of strips of the matrix, while the other coordinate set of strips is formed by depositing a layer 2 of material of high permeability and low coercivity into grooves in a copper or other thin non-magnetic metallic substrate 5. The metal substrate is flexible and may be bonded to a layer of compliant material such as rubber so that even contact with the glass substrate is obtained. Deeper grooves are provided in the copper substrate for accommodating a highcurrent bias conductor 6. Alternatively both substrates may be of copper or other metal, and both layers consist of magnetic storage material. The magnetic storage material may be a nickel-iron alloy and may be deposited on to a curved substrate which when subsequently flattened produces correct alignment of the easy axis of magnetization orthogonal to the grooves. The manufacturing processes involved in forming the substrates and layers are described in detail.

Title: Therapeutic compositions for injection
IPC: A61K9/00
Filed: 1962-09-27
Abstract: Therapeutic compositions for injection comprise finely divided micro-particles of a metabolisable substance having an active drug adsorbed thereon, said micro-particles containing said drug being encapsulated in a metabolisable film-forming substance and said encapsulated micro-particles being suspended in a physiologically acceptable or non-toxic liquid carrier.  The carrier may be an oil or saline solution, and when the former is used, the suspension may subsequently be emulsified in water; alternatively, the carrier may be a secondarily active substance, e.g. an anti-histaminic agent, or an anti-serium.  The particles on which the drug is adsorbed are generally those of starch, but milled particles of dry amino acids or nucleic acids are also suitable.  Suitable encapsulating agents include methyl, ethyl and hydroxyethyl celluloses, and low molecular weight polyethylene, polypropylene, polymethyl methacrylate, polyethyl methacrylate and polyethyl acrylate.  The invention is particularly applicable for administering drugs which are normally likely to produce adverse side-effects; such drugs include antigens, anti-allergic agents, e.g. anti-histaminic agents, toxins and allergenic materials, and extracts of pollen.
