摘要： A method of producing a fast-dissolving pharmaceutical delivery device of moderate strength. The delivery device is a fully formed tablet composed of readily available sugars, strength polymers and a volatilizable excipient along with an active ingredient and optional flavorings. The tablet as made will disintegrate in an aqueous medium such as saliva in under 15 seconds, making mastication unnecessary or at least requiring only one or two bites on the tablet. Essential to the invention is the easily obtainable particle size ranges of the sugars and the volatilizable excipient which promotes optimum release and tablet strength. The invention also allows for effective taste masking of the active ingredient with standard particle coating techniques.

摘要： Method and apparatus for the formation of granules of a larger size or mass of a desired range from a feed stock of smaller particles comprising feeding a meltable powdery material to be granulated, or a non-meltable powdery material with a meltable binder to the surface of a rotating spreader means in the form of a disk or bowl, at least a portion of which has been heated to a temperature above the melting point of the meltable component of the feed material wherein the rate of feeding, the energy input to the spreader means and the rotational speed of the spreader means are controlled so that there is sufficient time for at least a partial melting of the meltable component of the feed material substantially solely by contact with the heated surface of the spreader means, centrifugally spreading the material across the surface of the disk or bowl and dispersing the same from the edge thereof into an atmosphere cooler than the melting temperature to form the granulated product. For certain materials only a part of the powdery feed material is melted forming a liquid film carrying a major portion of substantially unaffected or minimally affected feed material to produce a product comprising individual granules containing a core as the major part of each granule with the original powdery material essentially unchanged maintained in self-sustaining form by a matrix of melted and resolidified particles bonded to each other at their surface.

摘要： A method of melt granulation for powdery material is disclosed wherein the powdery material is discharged onto the upper surface of a heated rotary spreader for migration under centrifugal force to the periphery of the spreader accompanying by melting of a portion of the material and enrobing of non-melted particles by the melted material for discharge as enlarged granules from the periphery of the spreader. To improve the quality of the granules produced, the feed material is supplied to the spreader at two separate locations. The first location is the central portion of the spreader to provide the melted material and the second location is adjacent to the periphery of the spreader. The spreader is preferably in the form of a concave bowl or inverted truncated cone or dish. Feed material is supplied to the first location by a screw feeder extending down the side of the dish and at the second location by a rotary vaned distributor located within the dish which radially flings the feed material onto the inclined dish wall. The process and apparatus is particularly useful for the production of non-sticky granules which are difficult to form when a single central feed of material is used.

摘要： An air classifier with enhanced air flow which maybe used for the simultaneous recovery of two or more distinct grades of foundry quality sand from a single sand stream. The air classifier exhibits improved performance by drawing into the classification chamber, through the use of suction, incoming air through a honeycomb followed by a screen section having two or more screens. The honeycomb removes swirl in the air and the screens slow down the fast moving air more than the slow moving air. After passing through the screens, the velocity profile of the air in the chamber is flat across the inlet flow path and, as a result, improved classification performance is achieved. Classification performance may be further enhanced through the use of a vibrating screen feeder for spreading the incoming particle stream before entrainment in the air flow within the classifier and through upward flowing air in one or more product receiver sections.

摘要： This relates to the provision of a vacuum actuated button type closure with a tamper indicating arrangement which will visually indicate when a container has been opened or more particularly when the vacuum within a vacuum packed container has been lost. The deflectable button of the closure is utilized to squeeze a dye from a sponge like member into a layer of absorbent material so as to color the absorbent material. The absorbent material, in turn, is provided with non-absorbent areas which define indicia to indicate that an associated container has been opened. The layer of absorbent material is carried by an arched cross sectional cover and in several forms of the cover, a central portion of the cover is downwardly deformable under pressure to move the layer of absorbent material from an inoperative position to a lowered position for cooperation with the sponge like member when the button returns to its up position to effect the flow of the dye from the sponge like member into the layer of absorbent material.

摘要： Solid particles or viscous liquid droplets of core material are encapsulated in a coating material largely as single particles with a single coherent coating, by feeding a suspension of the two materials onto a rotating surface. The suspension is centrifugally dispersed by the rotating surface into relatively large coated particles and relatively small droplets of coating material. Only the size of the droplets of unused coating corresponds to the droplets formed from atomization of the liquid coating material. The size of the coated particles depends on the size of the uncoated particles and is much less dependent upon the atomization characteristics of the rotating surface. Upon being thrown from the rotating surface, or falling from that surface, the droplets and coated particles are solidified by exposure to air and are separated by sieving, or the like. The solidified droplets of pure coating material may be recycled into the suspension. Coating of all particles is achieved by dispersing the individual components of core material in the coating material before the resulting suspension reaches the rotating surface.
摘要翻译：核心材料的固体颗粒或粘稠液滴通过将两种材料的悬浮液进料到旋转表面上，以大量单一颗粒与单一相干涂层封装在涂料中。悬浮液通过旋转表面离心分散成较大的涂层颗粒和较小的涂层液滴。只有未使用的涂层的液滴的尺寸对应于由液体涂覆材料的雾化形成的液滴。涂覆颗粒的尺寸取决于未涂覆颗粒的尺寸，并且远小于旋转表面的雾化特性。当从旋转表面抛出或从该表面落下时，液滴和涂覆的颗粒通过暴露于空气而固化并通过筛分等分离。纯的涂层材料的凝固液滴可以再循环到悬浮液中。所有颗粒的涂覆通过在所得悬浮液到达旋转表面之前将核心材料的各个组分分散在涂层材料中来实现。

摘要： Aluminum hydrogels which are stabilized at pH below 7 with a polymer containingcarboxyl groups, e.g., carboxy methyl cellulose or gum arabic. The gels are useful as phosphate binding agents in the treatment of hyperphosphatemia. Such polymers are incorporated during the formation of the aluminum hydrogel, permitting a high yield to be obtained, and preventing colloidal sol formation during exchange with monovalent anions.

摘要： A system and method for producing foundry quality sand from non-conventional starting materials through the combination of oolitization and classification. Incoming particulate matter is first directed into a controlled energy attrition unit where the particles are made to collide with one another. Such collisions clean and round the particles by chipping away surface projections and coatings without crushing the particles. The particle stream is then directed through a multi-fraction classifier where it is separated into two or more useable grades of foundry sand. An air classifier is preferred for the classification stage.
