Abstract: "FEEDR FOR ANIMALS"          ABSTRACT OF THE DISCLOSURE:        A feeder for animals particularly pigs includes a trough having a front wall, a base and a rear wall.  A shelf is positioned over the rear wall so as to project forwardly from the rear wall.  A hopper deposits feed onto the shelf so that the animal can eat from the shelf or brush the feed into the trough.  The shelf is separate from the rear wall so that it  can  be  raised  and  lowered  relative  to  the  rear  wall leaving a space underneath the shelf and at the top of the rear wall.   The trough can then be cleaned by injection of a liquid spray which cleans out the crevices of the trough and jets the material up the rear wall and under the shelf to be discharged through the floor.   The feeder can therefore be easily cleaned while it remains in a stationary position in the pen.

Abstract: 1522182 Calcium phosphate ceramics STERLING DRUG Inc 22 July 1975 [2 Aug 1974 7 July 1975] 30706/75 Heading C1A A polycrystalline, sintered ceramic for use as a bone or tooth substitute is made by reacting calcium ion with phosphate ions in aqueous medium at pH of 10-12 to produce a gelatinous calcium phosphate precipitate having a Ca:P molar ratio of 1À44-1À72, separating the precipitate from the solution and heating the precipitate to above 1000‹C but below the temperature at which appreciable decomposition of hydroxylapatite occurs and maintaining said temperature for a sufficient time to effect sintering and maximum densification. When the Ca:P molar ratio is in the range 1À62-1À72 a translucent, isotropic, polycrystalline hydroxylapatite having an average crystalite size of 0À2-3 microns, a density of 3À1-3À14 g/cm<SP>3</SP>, substantially no pores and having cleavage along smooth curved planes is obtained. When the Ca:P ratio is in the range 1À44-1À60, preferably 1À46-1À57 a dense isotropic two-phase ceramic is obtained comprising 14-98% hydroxylapatite and 2-86% whitlockite, said ceramic having substantially no pores and having cleavage along smooth curved planes. The reactants are preferably Ca(NO 3 ) 2  and (NH 4 ) 2 HPO 4 . 0À4-0À6% of an organic binder, e.g. collagen, may be added to the precipitate to prevent cracking during drying. Porous forms of the ceramic may be made by including 5-25% by weight of organic binders such as powdered cellulose, starch, cotton or collagen to the precipitate. Fluoride ions may be introduced into the ceramic, e.g. by standing in 0À5-5% aqueous NaF for 12 hours-5 days.

Patent NL-11302-C (NL)
IPC: F26B13/00
Abstract: Strands of artificial silk are so operated upon that during the final drying process the individual filaments forming the strand are kept in continuous relative movement, whereby they are prevented from sticking together and assume a more or less crinkled appearance, thus increasing the covering-power of the finished product.  The strands in skein form and finished except for drying are supported on rods, or upon a slowly rotating holder of diameter, say, half that of the skein, and are subjected to the action of a strong blast of heated air.  When the strands are arranged to be under tension during drying, the supporting-rods are slowly rotated, and the strands are subjected to an air blast after partial drying and after the tension has been partly or wholly released and the filaments are no longer in a hydrated condition.  A number of skeins may be treated in a chamber conforming to the shape of the skeins and of such dimensions that the air passes through the skeins.  A mechanical movement, effected by revolving the supporting-rods, may wholly or partly replace the direct action of the air upon the filaments.  A skein that is already dried may be treated as described above and sprayed with water or steam, so that the relative movement of the filaments is accompanied by a drying action.

Abstract: A circular section column with helical liquid flow is divided by a vertical wall 10 into two gas and vapor tight sectors A and B, each sector housing a series of trays. The trays disposed are designated respectively 1a, 2a and 3a for sector A and 1b, 2b and 3b for sector B. The distance D separating each two successive half trays of a given series is constant. On the other hand, the half-trays of one series are each staggered in the axial direction of the column with respect to the half-trays of the other series by a spacing d which is less than half the distance D. This arrangement allows a greater number of half-trays to be housed in a column of a given height, or the height of a column for a given number of trays to be decreased.
