Title: Anthelmintic compositions and their preparation
IPC: A61K31/66
Filed: 1965-11-01
Abstract: Anthelmintic compositions comprise particles of a solid core of dimethyl-2, 2-dichlorovinyl phosphate (DDVP) and/or dimethyl-1, 2-dibromo-2, 2-dichloroethyl phosphate (Dibrom.) in solution in a solid polyvinyl chloride resin, coated with at least one coating of a mixture of one or more polyhydric alcohols with one or more natural gums, and overcoated with at least one surface coat of an edible, moisture-resistant material.  The polyvinyl chloride is preferably a hydrophobic resin of M.W. at least 5000.  Suitable polyhydric alcohols have a water solubility of at least 50% by weight, and provide such 50% solutions having a viscosity of about 40 centistokes at 20 DEG C.  Specific examples are propylene glycol; 1, 3-butanediol; 1, 4-butanediol; glycerol; 1, 2, 3-hexane triol; erythritol; arabitol; sorbitol; and dulcitol; and the hydrates thereof.  Natural gums mentioned are tragacanth, acacia, asafetida, guaiac, gamboge, guar, karaya, sweet gum, and gum arabic.  Edible moisture-resistant materials include shellac; shellac with n-butyl-stearate, with wool fat, or with cetyl alcohol, ammoniated shellac; cellulose acetate; collodion; formalized gelatin; salol; salol with shellac; and keratin.  The compositions are prepared by coating particles of polyvinyl chloride containing DDVP and/or Dibrom, such as are known in the prior art, with an aqueous solution of the polyhydric alcohol, and then dusting powdered natural gum over them, suitably in a rotating coating pan, under streams of warm air, successive coatings being applied to the required thickness.  The overcoating is applied, in a similar pan, by treating with a solution of the edible water-resistant material in a polar solvent (e.g. ethanol, methanol, iso-propanol, or acetone) and removing the solvent.  The finished product may be dusted with e.g. talcum.  Also within the scope of the invention are animal feed compositions comprising an animal feed mixed with the particles of the invention. The coatings stabilise the sustained release resin composition core to prevent deterioration on storage when admixed with a foodstuff.

Abstract: 1462990 Continuous casting; straightening CONCAST Inc 28 Oct 1974 [29 Oct 1973] 46612/74 Headings B3F and B3E [Also in Division B8] In a guiding and supporting means, such as a roller apron or withdrawing or straightening apparatus, for a cast strand, a balance beam 23 (as described there is one at each side) is pivotally connected to two consecutive rollers 5, e.g. by way of pivot pins 21 extending from bearings 9 of the rollers, which are guided perpendicularly of the casting path by members 8; the beam 23 is also pivoted on pressure-loading means, such as a piston-and-cylinder unit 16 or screw means, and (since one pin 21 is mounted in a block 18 which is slidable in the beam 23) the distance between the pivotal connections is adjusted automatically with independent movement of the rollers 5 perpendicular to the casting path to maintain the projection of such distance in a plane parallel to the casting path substantially unchanged. Lower rollers 3 or the upper rollers 5 or both may be driven. The lower rollers may be yieldingly mounted and the upper rollers adjustable. Instead of having a sliding block 18, each beam 23 may be telescopic. In another embodiment, the two bearings 9 of each roller 5 are mounted at either end of a respective yoke (10) and the yokes of an adjacent pair of rollers are pivoted on a balance beam (13) at each end; the beams are each pivoted on a holding-down means anchored to foundations or to a frame member 6. If the rollers are short, a single balance beam connected to the yokes midway between their ends is sufficient. Divided rollers having three or more bearings may be mounted in a yoke. Specifications 1,277,689 and 1,273,701 are referred to.

Title: Improvements in Semiconductor Low Voltage Switches
IPC: H01L27/08
Filed: 1966-10-25
Abstract: 1,162,833. Semiconductor devices. GENERAL ELECTRIC CO. 25 Oct., 1966 [26 Nov., 1965], No. 47767/66. Heading H1K. A planar semi-conductor switch comprises a PNPN device with a reverse-biased control diode connected across the centre junction to trigger the current flow. The switch, shown diagrammatically in Fig. 4, may be made from an N-type silicon body 31, Fig. 5, by coating with a silicon dioxide layer 32 about 10,000 Š. thick, masking and etching the layer, and diffusing boron and phosphorus to form P-type regions 2 and 6 and N-type regions 8 and 22 respectively. Aluminium is then evaporated on to the body through a suitable mask to form a conductive path 28A and electrodes 14, 16. A plurality of switches may be made simultaneously in a single silicon wafer which is then sub-divided, the completed switches being permanently covered by an oxide or other layer and enclosed in an hermetic container or plastic encapsulant. In a modification, Figs. 13 and 14 (not shown) a bilateral switch is formed by connecting two control diodes across the respective centre junctions of an NPNPN structure. In a further modification, Figs. 6 and 7 (not shown), a switching current control resistance (40) is used to shunt one or both of the junctions (JA, JK). In Fig. 8 (not shown), the N-type region (22) of the control diode overlaps the N-type region (4) and makes non-rectifying contact therewith, thus eliminating the external conductive path 28A and the N+ region 29, and the function of the resistor (40) is performed by the inherent resistance of a portion of the region (6). This is achieved by partially shunting the junction (JK) by a metallic contact layer (33) which determines the current flow path.
