IPC: B41F3/30
Filed: 1923-08-01
Abstract: 219,502. Hall, J. Aug. 1, 1923. Cylinder machines ; offset machines.-A tworevolution flat-bed printing-machine is constructed so as to be capable of printing by the direct or offset methods by arranging an offset blanket on the impression or offset cylinder A and arranging an impression cylinder D behind the cylinder A. When offset printing occurs, an impression from the bed B is made on the offset blanket on cylinder A in its lowered position, and when it is raised a sheet is fed to the gripers a and is carried around with the offset blanket until it reaches the cylinder D, when it. is transferred to grippers d<1> on the cylinder D from which the printed sheet is delivered by tapes E and a flier e, or by grippers on a chain which deposit it printed side up. The cylinder D is controlled by trip mechanism E<1>, F<11> which moves the cylinder D out of contact with cylinder A after the offset printing has taken place, or the cylinder O may be arranged so that the rising and falling motion of cylinder A also moves the cylinder A into and out of contact with cylinder O. In a modification a delivery cylinder may be arranged in front of the feed board, and in this case the sheet is not carried round the cylinder D but after contact with cylinder D passes under the feed table and is delivered by the auxiliary cylinder just after passing the feeding-in position.

A bar-traveller for textile spinning machines has means for leading the material being spun to the package being formed and is of such flexibility as to be capable of yielding resiliently to the outward pressure of the package surface as the package diameter increases during winding. As shown a bar-traveller 16, which may be made of light strip metal, or thin plastic strip so as to be easily flexible is provided at each end with a bifurcated enlargement 161, the limbs 162, 163 of which engage over and under the rim of the ring 15. With the traveller illustrated in Fig 1 the roving 12 is led at the base of the balloon to an eye 164 then along the outer face of the traveller and through a second eye 165 at or near the point at which the roving is laid upon the package so that this eye serves to guide the roving directly to the winding point. In a second form of the traveller notches are provided on opposite edges of the traveller instead of the eye 164 so that the roving can be wound around the arm of the traveller once or twice before it passes to the winding point. The middle part 169 of the traveller is preferably enlarged so as to serve as a presser pad. When winding commences the traveller is in the position shown in Fig. 2 and when the package has attained its full diameter the traveller will be in the position shown in Fig. 3. The roving may be led from the rollers 10, 11 to the traveller either through a stationary eye 19 or through an eye (not shown) mounted centrally upon a member arranged to rotate freely upon the spindle 13.

Title: Improvements in and relating to anisotropic monotectic alloys and products produced therefrom
IPC: C22C49/00
Filed: 1966-05-05
Abstract: An anisotropic alloy composition is formed by unidirectionally solidifying a melt of a monotectic composition, the composition being such that one of the products of solidification forms as filaments embedded in a second product of solidification. Exemplified compositions are Sn-S, Cu-S, Ag-S, In-S and Tl-S. Impurities may be deliberately incorporated in the melt to impart specific properties to the matrix or filaments.  The filaments may be removed to produce a body of uniaxial porosity by reheating the solidified body to a temperature intermediate the melting points of the matrix and filament compositions and applying a pressure differential sufficient to eject the molten filament material.  Alternatively, the filament material may be evaporated under vacuum or dissolved.  The matrix may also be dissolved from the solidified body and the filaments utilized.ALSO:An anisotropic alloy composition is formed by unidirectionally solidifying a melt of a monotectic composition, the composition being such that one of the products of solidification forms as filaments embedded in a second product solidification.

Title: Process for the production of a sour-milk powder adapted for use in making baking powders or in making self-raising flour
IPC: A23C13/12
Filed: 1936-07-20
Abstract: A sour-milk powder adapted for use in making baking-powder or self-raising flours is prepared by first condensing milk or a milk product such as skimmed milk or cream, biologically acidifying it, e.g. by means of bacteria used as starters in treating cream for butter-making, and finally evaporating to dryness preferably by atomizing in a drying chamber.  The acidification is preferably carried out so that the dry substance contains 4-15 per cent by weight of lactic acid.  The powder may be mixed with a harmless carbonate or bicarbonate of sodium, potassium or ammonium or of the alkaline earth metals to give a baking-powder which may be diluted by mixing with starch or flour.  Flavouring materials, e.g. spices, vanillin, diacetyl, baking auxiliaries such as diastase and other enzymes, bromates, perborates, &c. which it is desired to add to the dough may be incorporated in the baking-powder.  The dried milk product and a carbonate may be added separately to flour to give a self-raising flour.  In an example, skimmed milk is pasteurized, cooled, evaporated at low temperature, preferably until at least 40 per cent of the water content is removed, cooled to souring temperature and treated with a pure starting culture with agitation to keep the milk homogeneous.  The product is atomized in a stream of hot air in a drying plant from which it is removed immediately.
