Filed: 1925-12-15
Abstract: 262,941. Farrell, D., and Helmholtz, A. W. Dec. 15, 1925. Blasting cartridges and fuzes.-A method of blasting consists in inserting a container into a drill hole, afterwards charging the container with a compressible fluid (such as carbon dioxide) which is not a liquid at atmospheric temperature and pressure, by forcing the fluid into the container from a source of supply under a pressure sufficient to maintain the fluid in liquid form, and finally gasifying the liquid by heating, so as to produce a pressure sufficient to burst the container. The figure shows the apparatus in use, 18 being a tank from which the fluid is forced by a pump 17 through pipes 16, 14 to a cartridge 11 tamped in a drill hole 12. A battery 20 is connected by leads 21, 22 to the heating devices in the cartridge. Two suitable forms of cartridges, described and shown, are also described and shown in Specification 259,799.

Title: A process for the simultaneous production from milk residues of animal fodder and alcohol
IPC: A23K1/00
Filed: 1936-11-25
Abstract: Animal fodder and alcohol are produced from milk sugar-containing residues from the working up of milk, such as skim milk, butter milk, and whey, by the addition of yeasts, such as kefir grains, that are adapted to produce coarse-grained or module-like fungus growths, which are separated out and dried. Ammonia, sodium, orthophosphate, calcium chloride, and sodium bicarbonate may be added to adjust the acidity of the liquor and to increase the size and number of the growths.  In some cases, air is blown into the liquor during fermentation.  In an example, kefir grains produced from whey and butter milk are covered with a layer of whey and maintained at a temperature of 37 DEG  C.  A mucilaginous mass is produced which after heating is passed onto drying rollers to yield a finely flocculent white dry product. The alcohol produced during the fermentation may be recovered by distillation, and in some cases, the protein is recovered and used for human nutrition or other purposes.ALSO:Animal fodder and alcohol are produced from milk sugar-containing residues from the working up of milk, such as skim milk, butter milk, and whey, by the addition of yeasts, such as kefir grains, that are adapted to produce coarse-grained or nodule-like fungus growths, which are separated out and dried.

Filed: 1957-10-16
Abstract: In the continuous fermentation of a yeast fermentable substrate such as brewer's wort to produce a fermented beverage, aerobic conditions favourable to yeast propagation are maintained in a yeast propagating stage and aerobic conditions favourable for alcohol production are maintained in a product formation stage, fermentable substrate is continuously introduced into the yeast propagating stage, effluent from the yeast propagating stage is continuously passed to the product formation stage, and yeast is separated from the effluent from the product formation stage and reintroduced in controlled amounts to the product formation stage to maintain the yeast concentration therein at a controlled level, preferably at 5 to 15% pressed cake.  A predetermined temperature of 45 DEG  to 90 DEG  F. is maintained in both stages, that in the yeast propagating stage being about 10 DEG  F. above that in the product formation stage. The product formation stage may be carried out in a series of separate series-connected vessels (Figs. 2 and 3, not shown).  It is stated that a flocculating yeast may be employed.

Title: Improvements in or relating to teleprinter keyboard transmitters
IPC: H04L13/16
Filed: 1965-07-29
Abstract: 1,064,138. Telegraphy. SIEMENS A.G. July 29, 1965 [July 30, 1964; April 30, 1965], No. 32411/65. Heading H4P. In a keyboard transmitter depression of a key causes transmission of one or another of at least two characters represented by the key. The particular character is chosen by a shift key which controls the longitudinal position of comb bars rotated by the key-actuated selector bar. Key 1 rotates a lever 3 pivotally and slidably mounted on a selector bar 2. A rocker 6 now rotates so that it engages a hook 5, sliding lever 3 rightwards until arm 14 engages the selector bar 2 and then moving that too. The selector bar, in one embodiment, carries two parallel rows of projections 17, each coded to represent a character on the key. One or other row engages with teeth on comb bars 21, Fig. 2 (not shown), which are thereby rotated clockwise. To select the other character the comb bars are moved longitudinally to align the gaps between the teeth with the first row of projections, and the teeth with the other row. In a second embodiment there is only one of row projections 17. These are not coded, instead some of the teeth on the comb bars 21 are omitted so that only those carrying teeth adjacent a projection are actuated.

Title: Improvements in controlling shutters of radiators for water-cooled engines
IPC: F01P7/10
Filed: 1922-11-28
Abstract: 211,942. Brown, C. A. Nov. 28, 1922. Radiators, aircraft and like. - A cylindrical, semicylindrical, or polygonal radiator for aircraft and other motors is provided with triangular or trapezoidal shutters arranged when closed to form a conical or like tapering surface at the front or the rear of the radiator body, and when open to give a substantially uninterrupted flow of air through the tubes or other cooling-elements. The shutters 11, Fig. 3, may each be pivoted along a middle axis 6 lying in the surface of a cone or pyramid extending from the radiator body 8 to a nose-piece 10 enclosed by a cap 18. The rear end of the radiator is fitted with a fixed tapering deflecting member 3. The axes 6 of the shutters are mounted at one end in a ring 7 attached to the body, and at the other end are fitted with toothed sectors 14 engaging a broad bevel wheel 13 on a shaft 15. This shaft may have a bearing in the nose-piece 10 and may extend through the centre of the radiator for operation, through a crank 16, by manual or thermostatio means, not shown, to regulate the cooling effect. The shutters may be hollow and of flattened crosssection, as shown in Fig. 6, or may consist of single bent sheets. In another arrangement the shutters may be pivoted along one of the long edges and be arranged to open inwards. In a further arrangement, shown in Figs. 15 and 16, the shutters may be pivoted along their short sides. Their pivots are mounted in brackets 28 on a ring 7 on the body, and the shutters may be operated through radial links 30 connected to a boss. 29 on a central rotatable shaft 15. They may be arranged to open to a divergent position. Alternatively, such shutters may be pivoted about middle axes to obtain a balanced effect. The radiator body is preferably isolated from the fuselage or motor so as to be freely exposed to the air currents, but it may be shaped so as to fit against a wing or the fuselage of the aircraft. A semicircular radiator may be suspended by straps 19, Figs. 7 and 8, from rigid tubes 20 carried in resilient buffers 21 mounted in sockets 22 attached to members 24 of the fuselage. The front and rear air-flow control means 11, 3 may be supported independently of the body, so as to leave gaps 25, 26 between the parts to allow of expansion or shock. These gaps may be closed by leather or other flexible material. According to the Provisional Specification, a series of sets of short shutters may be pivoted on axes lying in parallel planes at right-angles to the radiator axis, or a collapsable umbrella-like structure, a series of nesting truncated conical members, or an inflatable device, may be used.
