Patent GB-1298189-A (GB)
Title: Electromedical apparatus
Inventor: MIROWSKI M
IPC: A61N1/39
Filed: 1971-04-19
Abstract: 1298189 Cardiac defibrillator MEDTRONIC Inc 19 April 1971 [9 Feb 1970 (2)] 21311/71 Heading A5R A cardiac defibrillator comprises; storage means for storing electrical energy, an electrode for connecting the storage means to the heart of a patient, switching means operable to discharge the storage means through the electrode into the heart, sensing means for connection with the heart for continually sensing the heart function, and a discriminator associated with the sensing means and adapted to discriminate between normal heart function and cardiac fibrillation as sensed by the sensing means, said sensing means and discriminator being arranged for automatically operating said switching means, so causing the energy stored in said storage means to be applied through said electrode directly to the heart in order to defibrillate the malfunctioning heart. The sensing means may take the form of a probe in the right ventricle of the heart which is sensitive to the blood pressure in the right ventrical. By means of a bridge arrangement 40 a signal is obtained from the probe which is a measure of the pressure at the sensing probe. The signal is fed into a discriminator 42 which analyzes the signal and produces an output signal pulse the amplitude of which is above a certain predetermined level if the input signal is from a normal heart, but which is below said predetermined level if the input signal is derived from a malfunctioning heart. The output of the discriminator 42 is fed via a cable 56 into a sawtooth generator 44. If the signal pulses from the discriminator are above said predetermined level (i.e. if they correspond to a healthy heart) the sawtooth generator is triggered by each pulse and the characteristic sawtooth output (58) is obtained (see Fig. 4, not shown). If the signal pulses are below said pre-determined level (i.e. if they correspond to a malfunctioning heart) the sawtooth generator is not triggered by the pulses and its output voltage rises steadily (54). If the sawtooth generator is not triggered its output voltage after about six seconds is sufficient to turn on the transistor in the relay stage 46. This transistor in turn operates the relay 64 which connects a low voltage supply to a converter 48, the output of which (about 2500 volts) is applied to the capacitor 70. A resistor chain, neon tube 74, transistor 72 and silicon controlled rectifier 76 serve to discharge the capacitor through the electrodes 26, 28 when said capacitor is fully charged. If at any time after the initial sensing of a malfunction the heart resumes normal operation the sawtooth generator will be triggered, causing the relay to revert to its open circuit state and stop the charging of the capacitor; thus if the heart re-starts of its own accord no shock will be delivered. After the first shock, if the heart does not restart further shocks will be delivered at time intervals the duration of which is equal to the sum of the time delay caused by the sawtooth generator and the time taken to charge the capacitor.

[Class 120(i)] Fibre is produced from sisal leaves, by crushing them between rolls so as to avoid bruising or other damage to the fibre, retting the crushed leaves in an alkaline solution at a temperature of about 99 ‹F. and washing the retted fibre. The leaves may be crushed between corrugated rolls having shallow flutings, parallel to their axes, about “-inch deep and of 3-inch pitch, and then passed between smooth rolls. The washed fibre may be dried and brushed or finished by dry rolling. Freshlycut leaves may be heated on the field, a portable crushing machine being used.

Abstract: 1,113,237. Plutonium separation. COMMISSARIAT A L'ENERGIE ATOMIQUE. 20 May, 1965 [19 June, 1964], No. 21460/65. Heading G6R. An aqueous solution of plutonium of sulphate content less than 0À2M is concentrated and purified, for example from uranium and fission products, by counterourrent extraction of plutonium with an orgunic phase containing tributyl phosphate, contacting the organic phase with a solution of uranous nitrate to reduce the plutonium to the trivalent state, extracting the plutonium with a solution of hydrazine in nitric acid, and recycling a portion of the aqueous phase to the first extraction together with the original solution; the recycled portion is oxidized to bring the plutonium back to the tetravalent state. The tributyl phosphate may be diluted with dodecane, CCl 4 , or an aromatic oil distillate. The aqueous solution from the re-extraction step is preferably scrubbed with pure organic solvent. The uranous nitrate reducing solution preferably also contains hydrazine. The oxidation may be effected with nitrous vapours, followed by removal of the nitrous vapours by agitation with air. Each countercurrent extraction step may be carried out in a battery of mixing- settling tanks.

Title: A process for the ornamental coating of surfaces
IPC: B05D5/06
Filed: 1936-08-10
Abstract: A surface is provided with an ornamental coating by first applying a basic varnish and then, while the basic varnish is still wet, applying another varnish, the decoration varnish, which contains a volatile solvent, the ornamental effect arising during the evaporation of the volatile component.  The basic varnish may be an oil-resin composition, and the decoration varnish, which may contain coloured pigments and/or metal dust, may be a cellulose acetate or a nitro-cellulose varnish containing acetone, or a spirit varnish.  The decoration varnish may be applied to the wet basic varnish by dipping or spraying, and, as its volatile component evaporates, various configurations such as stripes, wavelines, dots, spots &c. are formed, and may remain on the surface of the basic varnish, or may sink into the latter and become fixed therein.  A final transparent protective coating may be applied.  The character of the configurations formed may be modified by adding to the decoration varnish, petrol, paraffin oil, oil of turpentine, or trichlorethylene, and the rate of evaporation of the volatile component may be regulated by the addition of e.g. tricresyl phosphate.  According to examples, decoration varnishes comprise: (1) a cellulose - derivative varnish, actone, turpentine, and ethylene glycol, with or without paraffin oil; (2) a cellulose-derivative varnish, acetone, petrol, and tricresyl phosphate.  Reference has been directed by the Comptroller to Specification 387,055.
