Title: Improvements in machines for dividing dough and imparting the desired shape thereto
IPC: A21C7/01
Filed: 1934-04-19
Abstract: 441,828. Dividing and rolling dough. PEA, A., 13, Via Nicola Bonservizi, Brescia, Italy. April 19, 1934, No. 11865. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 20, 1934]. [Class 87 (ii)] In a machine for dividing dough and then rolling the pieces first into spherical and afterwards into longitudinal or cylindrical shapes, the division is obtained by the movements of two blocks 4, 5 which have the shape of annular segments and are mounted freely upon a revolving drum 3 about which they are stopped or set in motion by teeth 9, 10, 11 controlled by cams. As shown in Fig. 1, the block 5 is prevented from turning by the tooth 10 and the block 4 is being moved over to the right by the tooth 9 to entrap dough from the hopper 1 in a space 6. When the enclosing of the dough in this space is almost complete, the tooth 10 is moved out by its cam to release the block 5 which under the pressure from the confined dough behind it is moved forward until it is stopped by the tooth 11. The dough piece then falls through the opening 12 on to a belt 15. The operation is repeated with the blocks in reversed position, the tooth 9 being released bv its cam from the block 4 and then carried round to engage the block 5 from which the tooth 11 is disengaged by its cam. The quantity of dough entrapped can be varied by adjusting the tooth 10 by the hand wheel 14. A knife 23 may be used so that the dough falls in two pieces instead of one. The rolling into spherical shape is effected by a hinged guide 16, Figs. 3 and 4, extending across the width of the belt 15 and held in position by a crossmember 17. To form the elongated pieces, the rounded pieces are conveyed to the centre of the belt by appropriate movement of the guide 16 and they then fall upon a board 18 against which they are rolled by the lower run of the belt, the pressure being regulated by a board 19.

Patent GB-793607-A (GB)
Title: Improvements in or relating to the purification of materials
IPC: H01L21/00
Filed: 1956-04-19
Abstract: A material, e.g. a semi-conductor such as germanium, containing impurities having segregation constants as hereinafter defined of approximately unity and which cannot therefore be separated by progressive solidification from the liquid phase, is purified by converting said material and the impurities to compounds which can be thus separated, separating the impurities by said progressive solidification and reconverting the purified compound to the original material.  The segregation constant of an impurity is the ratio of its concentration in the solid phase to its concentration in the liquid phase.  Impure germanium may be first converted into a halide such as tetrachloride or tetrabromide, and a vessel containing the liquid halide is then gradually lowered into a cooling medium such as liquid air or solid carbon dioxide, preferably whilst stirring the liquid phase above the solid which forms.  To prevent super-cooling of the liquid the part of the vessel which first enters the cooling medium is preferably provided with a downward extension of small cross-section in which the first portion of solid is formed.  The impurities are sequestered either in the solid which is first formed (if the segregation constant is greater than unity as in the case of silicon and copper in germanium) or in the liquid which is finally left (if the segregation constant is less than unity as in the case of phosphorous, selenium or sulphur in germanium).  The pure halide is separated and the process may be repeated several times. If more than one impurity is present and the segregation constants lie on opposite sides of unity, the vessel containing the liquid tetrahalide is slowly lowered until about half the contents are solidified and the solid and liquid portions each containing an impurity or impurities of only one kind are separated and treated as previously indicated.  Purified germanium tetrachloride may be reconverted to the element by hydrolysing to the oxide and reducing with hydrogen, or by electrolysis.  The invention is stated to be applicable also to compounds having elementary or compound impurities.

Patent GB-494969-A (GB)
Title: Improvements in or relating to the production and treatment of textile materials
IPC: D06M11/38
Filed: 1937-05-04
Abstract: Textile materials containing both yarn of an organic ester of cellulose and yarn of an organic derivative of cellulose which has been esterified while in yarn form, are treated with saponifying agents so that the former yarns obtain an affinity for cotton dyestuffs, while the latter yarns are substantially unaffected. The degree of saponification is preferably not such as to destroy the affinity of the yarns for dyestuffs which normally have affinity for organic esters of cellulose.  Suitable esterifying processes are those described in Specifications 448,816, 448,817, and 448,917.  The two types of yarn may be associated together in any way to form a fabric, for example, warp yarns of ordinary organic esters of cellulose may be associated with weft yarns of organic esters of cellulose which have been esterified, or the two yarns may be woven together to form a fabric in which one type of yarn forms a pattern on a background of the other type of yarn, or again, the two types of yarn may be associated together to form mixed yarns.  In a modification, a fabric made from ordinary yarns of organic ester of cellulose is esterified locally in any desired pattern.  The textile materials may also contain other types of yarn, e.g. regenerated cellulose yarns, cotton, silk, or wool. Suitable saponification processes for the mixed yarns are those described in Specifications 316,521, 318,468, [both in Class 2 (ii), 417,220, 429,103, 453,302, 476,229, 478,077, and 488,946. The colouration of the organic derivative of cellulose yarns which have been esterified may be effected by means of the S.R.A. dyestuffs, and of the ordinary organic ester of cellulose yarns by dyestuffs which contain hydrophile groups which do not possess in the dyestuff any strong auxochromic effect, as is described in Specification 493,519.  The partially saponified yarns may be dyed by means of dyestuffs for organic ester of cellulose yarns, or by means of cotton dyestuffs. Specification 343,953 also is referred to.

Abstract: 516,422. Impedance networks; valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO.; Ltd., and RUST, N. M. April 28, 1938, Nos. 12771/38 and 30614/39. Addition to 474,387. [Classes 40 (iii) and 40 (v)] In a filter with adjustable band-width for superheterodyne intermediate frequencies and like purposes, tuning-condensers IT, OT, are shunted across inductances which are coupled inductively at M and also through a crystal X. The coils coupled at M, Fig. 1, may be replaced by a single coil, Fig. 2 (not shown), which may be in series with a resistance, Fig. 3 (not shown), or a resistance may be inserted in series with the coupled-coils M, Fig. 4 (not shown). The crystal X is shunted by an adjustable condenser VC and may be connected between the upper ends of the inductances or between tapping- points TI, TO. The capacities IT, OT may be ganged so that one increases while the other decreases, and the tappings TI, TO also may be ganged. The transmission characteristic may be varied as follows : (i) the slope of the skirts sk1, sk2 near the cut-off frequencies f1,f2 may be varied by simultaneous adjustment of the parts M, VC, Fig. 5 ; (ii) the cut-off frequencies f1, f2 may be shifted in one direction to produce asymmetrical skirts sk1, sk2, the flat top t remaining stationary, by altering either the inductive coupling M or the capacity VC, Fig. 6 (not shown) ; (iii) the top t may be narrowed, the cut-off frequencies f<1>, f2 remaining constant while the skirts sk1, sk2 are deformed, by adjustment of the tappings TI, TO or of the condensers IT, OT, Fig. 7 (not shown) ; (iv) the band-width may be changed, the shape of the skirts remaining unaltered, by simultaneous adjustment of the parts M, VC, and TI, TO or IT, OT. The specification gives calculations, taking account of the resistance inherent in the inductances, relating the arms of a pi-section, Figs. 9, 10 (not shown) equivalent to the network under the invention. In a modification, Fig. 11, the need for a condenser VC shunting the crystal is eliminated, and difficulties arising out of the setting of the coupling M to neutralize the capacity of the crystal-electrodes are avoided, by the use of a coupling condenser C instead of the mutual coupling M. In further modifications, the coupling M may be shunted by a condenser Fig. 13, (not shown), or replaced by a single anti-resonant or resonant circuit, Figs. 14, 15 (not shown). The effective impedance may be raised by shunting negative impedance upon the input and output terminals. Valve circuits. An intervalve coupling in the intermediate-frequency amplifier of a superheterodyne receiver, constructed as described above, may be provided with magnetic, resistance-capacity or other reaction coupling to sustain the attenuation outside the pass band and the impedance inside it.
