Convention date, April 2, 1929. [Class 86.] Margarine and other edible fats are kneaded in an apparatus comprising a number of chambers through which it is passed in series, each chamber being fitted with a worm the capacity of which varies along its length either by varying the pitch or the width of the blade. In the form shown in the Figure, the material is placed in a hopper a from which it is passed through the chamber b by the worm s of which the pitch gradually decreases. The material then passes through a connecting tube t to the succeeding chambers c, d. The connecting tubes t, v may each be fitted with a shutter j, and discharge orifices h may be fitted so that the material may be passed through only one chamber. An auxiliary hopper f, fitted with a discharge worm e, supplies an ingredient such as salt for mixing with the margarine &c. In other forms, the chambers may be longitudinally divided and each part provided with a worm, or a feeding hopper may be provided at the end of each chamber. The worms may be heated by circulating heating fluid through the shafts, and the connecting channels may be jacketed. Each shaft may have two or more worms in series.

Abstract: 953,254. Heat developable diazotype material. EUGENE DIETZGEN CO. March 9, 1962, No. 9111/62. Drawings to Specification. Heading G2C. A two-component diazotype material consists of a vapour permeable paper or cloth support with a diazomium compound and an azo coupler on one side and on the other side a compound which evolves alkaline vapours on heating up to 400F. The light sensitive side is exposed imagewise and developed by heating the reverse side so that alkaline vapours pass through the support. Specified alkali-generating compounds are urea, guanidine, alkyl substituted ureas, ammonium carbonate, acetate, diglycolate and oleate, ethylene diamine and N<SP>1</SP>-(2-hydroxyethyl)-2-methyl-1,2-propanediamine. In the development step, the alkaline vapours are confined to the diazo layer either by applying a resinous layer over the diazo layer before exposure or by applying a metal plate during development. Organic acids such as tartaric, citric, diglycolic, oxalic, acetic and malic acids or acidic salts such as stannic chloride may be added to the alkali-generating layer to improve its stability. The alkali-generating compound is generally applied to the support mixed with a resin and silica to ensure that on heating the vapours do not escape but pass through the support.

[Classes 75 (i) and 75 (iv)] [Also in Group XV] A Chistmas-tree ornament comprises a pair of dished members 17, 18 made of still paper covered with aluminium foil and joined together at their edges by rivets or staples 19 or by adhesive to form a hollow ornament 15 having the shape of a maple leaf, Maltese cross, &c. ; alternatively, the members may be cast out of glass, such as phenol or urea formaldehyde condensation product resin-glass. A wire support 21 is secured to the member 17 or to a cardboard annulus 24 stapled to the member 17, the lower end of the wire 21 being formed as a hollow cone for mounting on the tree. One of the members 17, 18 may be smaller than the other so that the larger member is drawn into a dished shape when the two members are secured together at their peripheries ; also, a lamp bulb 32 is mounted inside the ornament by means of a fork-like tab 33 projecting from the disc 24 and gripped between the Lamp and its socket 34. The members 17, 18 may be secured together by means of integral lugs on one member passed through slots in the other and bent over, by folding and crimping complementary tabs on both members, by folding and crimping the edges of the members, or by sewing the edges together. The following modifications are described: (1) The members 17, 18, Figs. 9 and 10 (not shown), are provided with slots which may be covered with " Cellophane " (Registered Trade Mark), and a lamp bulb passed through a central aperture in one member is screwed into a socket placed behind an aligned aperture in the other member, the bulb projecting outside the device if desired. (2) The ornament is laid flat and is employed as a candle-holder, the candle resting on the rear member and projecting through an aperturo in the front member. (3) One of a pair of dished members, Fig. 11 (not shown), is slightly larger than the other, thus forming a lighted border providing a halo effect. (4) A blank, Fig. 12 (not shown), is stamped to produce the dished formation, and is then folded and the edges joined together. (5) One of a pair of members 71, Fig. 14, of similar shape has lugs 72 which are bent over the other member to provide temporary attachment while flanges 73 are bent over the edges of the other member. In the stamping operation, holes 74 to simulate lace or filigree work are formed, and the dies used to shape the blanks also produce outlining ribs or corrugations 75. (6) A star-shaped ornament comprises two parts stapled together at the points and at the inside corners, Fig. 15 (not shown), a central aperture and peripheral apertures being provided.
