Patent GB-750797-A (GB)
Title: Process of manufacture of an antibiotic product having a specific action against the microbes causing fermentation and decomposition of foods, and product obtained thereby
Filed: 1953-03-26
Abstract: An antibiotic having a specific action against particular microbes causing decomposition of foods wherein the bacteria causing the decomposition are allowed to grow on the food in question and are then subjected to a slow death by certain specified physical and chemical means whereby an antibiotic is produced having the property of preserving the food in question from decomposition by the bacteria producing the antibiotic. Physical means causing the slow death of the bacteria are ultra-violet, infra-red and X-ray radiations, Wood's light high-frequency electric currents, microwaves and ultrasonic radiations.  Chemical means are (a) organic salts of heavy metals such as lead, tin, zinc, cerium, thallium and antimony with chloroacetic, tartaric, citric or hydroxyglutaric acid which are soluble in water at the concentrations required; (b) toxic gases such as chlorine, phosgene, ammonia and hydrogen sulphide; (c) hydrosulphites, aldehydes and peroxides which effect the redox potential of the medium; and (d) sodium fluoride and glutathione which influence the metabolism of the microorganism.  The antibiotic is recovered by macerating the culture with water and sand, filtering and concentrating.  Amongst the food fermenting micro-organisms specified are B. putrefaciens, B. septicen, B. coli, Aspergillus, Penicillium, Streptomyces griseus, ycast, and Proteus vulgaris.ALSO:An antibiotic produced by cultivating a particular type of food-decomposing microorganisms on the food in question and subjecting them to a slow death by certain chemical or physical means (see Group IV(b)) is added in quantities of 1 to 2 per cent to the food to be preserved e.g. to orange, grape and pear juices and pulps, meat extracts and milk.

Filed: 1930-07-01
Abstract: Perforated articles of rubber or the like are electrophoretically deposited from aqueous dispersions on a conducting base, e.g. of zinc, provided with perforations plugged with insulating material such as ebonite.  The plugs are preferably raised above the base. Natural or artificial dispersions of rubber, guttapercha, balata, and similar vegetable resins in vulcanized or unvulcanized condition, and dispersions of coagulated or vulcanized rubber, waste or reclaim may be employed. Concentrates according to Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be employed.  Latex may be treated and the deposition carried out as set forth in Specification 257,885, [Class 70, Indiarubber &c.].  In making corsets by this method a cotton gauze reinforcement is incorporated at the edges by laying the gauze against the anode and depositing the rubber through it.  The dispersion employed may contain 40 per cent of total solids of the following percentage composition by weight viz.: rubber 73,25, sulphur 3,75, lithopone 15,75, accelerator 1,0, anti-ager 1,0, zinc oxide 4,75, pigment 0,5.

Title: Improvements in electric relays especially suitable for wireless telegraphy
IPC: H01H50/74
Filed: 1921-03-22
Abstract: 160,730. Boucherot, P. March 24, 1920, [Convention date]. Relays.-A relay specially adapted for the automatic transmission of morse or other code signals by wireless is interposed between an automatic interrupter of the wheatstone-transmitter type and an auxiliary source of power, which is thereby brought into action in order to make and break the heavy currents characteristic of the ordinary type of wireless transmitter. The elements of the relay are shown diagrammatically in Fig. 1, and comprise a reciprocating member 1, driven at a constant frequency by a suitable motor, and cooperating with a contact-member 3 through an intermediate spring-influenced member 2. The time-intervals of contact between the members 2 and 3 will vary according as the member 2 is locked to the member 1, or is free from that member and is locked during given periods to one or the other of the members 5 and 6. Springs 3 and 4 are arranged so that there is no resultant force upon the member 2 when in its mid-position, as shown in Fig. 1. Electric, pneumatic, and mechanical means are described for locking these members together for the intervals necessary to transmit either a dot or a dash. As illustrated in Fig. 6, the members 1 and 2 are locked together by means of racks 24, shown in plan, Fig. 7, and whilst so locked the member 2 oscillates between the members 5 and 6, which form the poles of an electromagnet 7 energized by a coil 8. When the member 2 is freed from the oscillating part 1 it is magnetically locked to one or other of the poles 5, 6. The locking and unlocking of the members 1 and 2 is effected by means of levers 27 which, owing to the movement of the reciprocating member 1, compress springs 28 against hammers 26. The hammers are freed by means of triggers 29 so as to strike against cross-bars 25 connected to the ends of the racks 24, and thereby move the racks laterally so as to lock or unlock the parts 1, 2. This operation is effected by means of a reciprocating wedge 60 the position of which is controlled by the wheatstone interrupter so that it comes between the nose of one of the levers 61 and the reciprocating member 1, thereby displacing one of the triggers 29 and freeing the corresponding hammer. The blow of the hammer is timed so as to move the racks 24 at a moment when there is no lateral pressure existing between the two members 1 and 2.
