Title: Improvements in dough-making processes
Inventor: SUGDEN GEORGE HIGHLEY
IPC: A21D6/00
Filed: 1964-03-12
Abstract: A process for making bakers' dough from cereal grains, of the type wherein the grains are submitted to a dry milling process in roller mills or other grinding machines and the product is cassified by sieving into two fractions and one of the separated fractions is mixed with liquid to produce a slurry that is subsequently divided to yield a product which in combination with usual dough making additives is mixed with flour yielded by the other separated fraction, is modified in that the sieving stage following the dry milling of the cereal grains is arranged to yield three fractions these being, an endosperm fraction comprising non-fibrous constituents of the grain amounting to not less than 60% of the weight of the whole grain and containing substantially all the flour produced by the dry milling operation, a bran fraction containing substantially all the bran flakes which are free from adherent endosperm particles, and a remainders fraction (offal) having a bran content of not more than 3% of the grain weight and comprising substantially all the endosperm constituents of the grain having fibrous attachments, which remainders fraction is submitted to a process of agitation or impact milling in the presence of water or an aqueous solution to produce a slurry which is subsequently classified by screens and/or centrifuges to yield three fractions these being, a liquid fraction which is re-circulated to the slurry mixing apparatus, a disposable fraction comprising substantially all the wet fibrous constituents of the slurry, and a semi-solid fraction comprising the endosperm constituents of the slurry and such proportion of the liquid as will maintain the fraction in a semi-solid state, which semi-solid fraction together with known proportions of usual dough-making additives is mixed with such proportions of the flour yielded by reduction of the endosperm fraction released by the said sieving stage as will ensure that the percentage of water in the dough produced by kneading the said mixture will not be less than 44% and not more than 49%.  Preferably the classifying means is arranged so that the semi-solid fraction is separated out from the slurry in a first classification stage and the liquid fraction is separated out in a subsequent second classification stage.  A flow diagram of an apparatus employed in the wet cycle of the process is given and includes the automatic control of the addition of make-up water and of the recirculation of the liquid fraction to the slurry mixing apparatus.  A ring main for supplying the final endosperm slurry to a bakery from and returning to a collecting reservoir is also specified.

Title: Process for the production of sheets, bands, wires and the like from ferro-silicon alloys for the improvement of their electrical properties
IPC: C21D1/78
Filed: 1927-04-22
Abstract: 276,953. D÷hner, O. H. Sept. 4, 1926, [Convention date]. Physical or molecular structure, altering by mechanical treatment.-Sheets, bands, wires &c. of iron alloyed with silicon for making transformer and dynamo laminations, meter limbs &c. are produced (by critically working them one or more times at temperatures below 600‹ C. and then heating them to recrystallization temperature, e.g. 650‹ to 900‹ C., so as to increase the size of grain and thus improve their electrical properties, including a reduction in the watt loss. The critical working consists in deforming the metal to such an extent that coarsening of the grain occurs when it is subsequently heated. As an example, iron containing 0.7 to 0.9 per cent of silicon is formed as usual into a plate 0.53 mm. thick. It is then critically deformed by cold rolling to 0.53 mm, in thickness, then heated at 750‹ C., then again rolled to 0.5 mm. thickness and then again heated at 750‹ C. The alloy thus produced has a maximum watt loss of 2.9-3 watts per kilogram at 50 cycles with B=10,000. The Specification as open to inspection under Sect. 91 (3) (a.) comprises also a modification in which the materials are critically deformed at temperatures above 600‹ C., e.g. above a dark red heat and then heated at recrystallization temperatures. It is also stated that the process is applicable to metals other than iron or metals alloyed with substances other than silicon. This subject-matter does not appear in the Specincation as accepted.

A vehicle comprises a false tipping chassis C actuated by an elevator mechanism D until a supporting stand K with a roller 1 contacts the ground and has a winch M acting on a cable to draw up a girder G provided with means to attach it to a standard transport container P. The girder G, Figs 8, 10, has clamps 8 pivoted on vertical pivots and comprising a shoe 17, 18 which contacts the front and side panels of the container and a plate 14 with a pin 16 which enters a standard hole 4 of the container and can be locked therein by a pin 22. The girder also has rollers 31 and counterweights 32 on a pivot 30 on supports 29 pivoted at 28 on a cross-beam 11 of the girder. As the girder is rested on the ground, Fig. 14, the rollers 31 are pivoted upwards until it rests on its shoes 24 but as the girder is raised during loading, Fig. 16, the counterweight will place the pivot 30 forward of the pivot 28 so that as the weight of the container forces the rollers 31 upwards a stop is contacted which holds the rollers proud of the shoes 24 to roll up the rails 35 of the chassis C. At the end of chassis C a roller bogy H, Fig. 18, is mounted comprising rollers 44 on pivots 45 in side plates 46 pivoted at 43 on a cross-beam 41. At the end of the chassis, Fig. 20, clamp plates 9 are mounted on plates 54 supported on parallel struts and upon operation of a jack 55 when the container is fully loaded the container is clamped to the chassis by projections 55 entering standard corner holes 5 but first the end of the container is raised to allow the clamps to position it centrally on the chassis. In order to prevent distortion of the longitudinal members of the container where they are weakened by fork lift holes the chassis may be mounted as in Fig. 32 by equal length support rods pivoted on differently spaced pivots so that by operation of a jack 113 together with the elevator D the linkage may be deformed and the chassis brought to the ground at a more acute angle so that the fork holes have passed the bogy H before they are contacted. Additionally, the rollers of the bogy may be replaced by an endless roller track.

Title: Improvements in and relating to protective devices for dynamo-electric machines
IPC: H02K17/14
Filed: 1922-04-20
Abstract: 199,201. English Electric Co., Ltd., and Ayres, W. E. M. April 20, 1922. Alternating-current induction machines; protective or safety devices, auxiliary; motors, controlling.-Relates to the protection, by overload trip coils, of electrical apparatus, for example, three-phase induction motors having windings which are connected with the trip coils and are adapted to be changed so as to produce alternatively two different groupings, elements of the windings being in one case in series and in the other case in parallel. According to the invention, in order that the trip coils may have the same setting and be equally effective with both arrangements of connections, each trip coil is associated with one half of a phase winding so as to receive the current of that half only for both groupings. As shown in Fig. 1 applied to a three-phase induction motor working with two pole numbers in the ratio of two-to-one for giving two different speeds, the, stator winding of each phase is in two parts 1-6. The pole-changing is effected by five two-way switches 11-15 all connected to a common operating member. When the switches are in the upper position, the stator has the maximum number of poles and gives a slow speed. The windings 1-6 constitute a single star, the two halves of each group being connected in series, and the overload coils 26, 27, 28 connected in each phase. When the switches are reversed, the number of poles is reduced to half and the speed doubled. Each phase is connected at the middle to the line and the end points are joined together to produce two parallel stars. The trip coils are connected in one only of these stars namely the inner one and, consequently, have the same current setting as before. The protection may be obtained by means of two trip coils each divided into two sections, the four half coils being connected to the winding to the change-over switch in such a manner that the two halves of the coil are in communication with a single phase of the winding for both groups, each of the two halves being in connection with a phase different from that with which the other half is connected.
