    摘要: The method of supplying nutrient liquid to a plant growing system comprising a series of many planters that are essentially alike and that are disposed at a common level, the system including a supply line extending from a supply point to the planters in succession, including the steps of first supplying a first nutrient liquid to the supply line at the supply point under pressure so that the planters receive nutrient liquid to progressively lower levels in relation to their distances from the supply point due to attenuation of pressure along the supply line, interrupting the supply of liquid for equalizing the levels of liquid in the planters, thereafter supplying a second nutrient liquid different from the first at the supply point so that the planters receive such second nutrient liquid to progressively lower levels in relation to their distances from the supply point, and interrupting the supply of the second liquid for equalizing the levels of liquid in the planters, thereby to develop a range of different nutrient liquids in the successive planters.

    摘要: A flotation-type, low-pressure-gas (or fluid) cushion for the prevention of pressure sores is provided, which has a plurality of longitudinal compartments, wherein outer compartments are of much greater size than the inner compartments, and communicate with the inner compartments by restrictive passageways. When a user sits upright on the cushion, a substantially lower pressure is exerted on the coccygeal and anal/genital regions, relative to other regions. The larger outer compartments extend past the hips and trochanters of the user, thus increasing the area of surface contact, relative to prior art cushions. A modification of the cushion includes a surrounding envelope which contains fluid, but at a lower pressure than the fluid or gas pressure of the inner cushion. The additional outer fluid system exerts a relatively low, equalizing pressure on all portions of the contacted anatomy of the user. The inner cushion continues to exert differential pressure. The resultant pressure on the coccygeal and anal/genital regions equals approximately only the pressure of the outer system, whereas the pressure on other regions of the anatomy, such as the ischial tuberosities, equals the sum of the pressures of the respective systems. The said sum of the pressures generally is less than half the pressure ordinarily exerted against the ischial tuberosities by a folding wheelchair, flexible sling-type seat.

    摘要: Cellulose cyanoacrylate is employed either to bond two surfaces or to duplicate the shape of a three-dimensional object. The method is carried out by applying a release material to the object to be duplicated, applying a sheet of cellulosic material formed of wood fibers onto the three dimensional object, then saturating the sheet of cellulosic material with a cyanoacrylate glue and permitting the saturated sheet to cure. The resulting product duplicates the shape of the object. Two surfaces may be bonded by placing a sheet of cellulosic material between the two surfaces and applying the cyanoacrylate glue to edges of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulosic material. This material may also be employed in bone or tooth repair. A break or fracture in an article can be repaired by positioning a sheet of cellulosic material over the break, saturating it with cyanoacrylate glue, and holding the saturated sheet in place with a releasable film. Irritating fumes may be suppressed by covering the saturated cellulosic material with a release film.

    摘要: The disclosed container for fluids has a pouring spout, the periphery of the container when empty and flat being defined essentially by straight side margins, and top and bottom margins that are curved inward and outward, respectively. A series of containers, formed of strip material, makes efficient use of the strip material by avoiding waste and by realizing a remarkably high ratio of container volume to area of wall material. The disclosed containers have a hang-up tab at the upper end of the container remote from the spout, the container being proportioned to avoid spilling of contents from the spout when the container is suspended by its hang-up tab.

    摘要: A coupling device is described and formed of a flexible tubular outer connecting element and a more rigid insert element sized to snugly fit into the bore of the connecting element. The elements are formed of vinyl material of different hardness so that their connection is accompanied with high frictional surface engagement. The resilience of the outer connecting element is selected sufficiently high to contract slightly and more tightly grip the insert in response to a separating force while facilitating connection with a slight expansion in response to a compressional connecting force applied to the elements. In one embodiment a ring fastener is formed for use as a key ring, or loose-leaf paper binder, apparel fastener and the like. Several embodiments are described.

    摘要: Opposed strips of heat-sealable thermoplastic strips are advanced along a path past a pouch-forming and incomplete cut-out zone, a filling zone and a pouch-sealing and cut-off zone. Each incompletely cut-out pouch has a spout whose open end extends to opposed marginal bands of the strips. Nozzles are projected into the spouts at the filling zone. A tight fit of the nozzles in the spouts prevents escape of fluid around the nozzles during the filling operation. The marginal bands of the strips are gripped adjacent each spout to enable the nozzles to be pushed into the spouts. The filled pouches settle onto a conveyor while the marginal bands hold the open ends of the spouts at a higher level, preventing discharge of fluid from the spouts until the filled pouches are sealed. Sufficient height of the spout opening above the mean level of the filled body of each pouch tends to form a discharge-blocking pinch across the spout, and a still-higher level of the spout opening prevents the discharge of fluid by gravity. Filling nozzles extend in opposite directions toward the centerline of the strips for insertion into oppositely directed spouts where the pouches are formed at successive positions along the strips and each slender spout lies between the bodies of neighboring pouches. Multiple pouches can be formed simultaneously by multiple seam-forming and cut-out reciprocating dies. Composite cut-out dies and seam-forming dies are heated to relatively high and lower temperatures, respectively, and the dies press the thermoplastic strips against a heat-resistant rubbery platen.

    摘要: A stack of many films of thermoplastic material is divided into sets of films by interposed layers of seal-inhibiting material. A heated cutter as of copper is used having a heat-storage portion and a blade projecting from the heat-storage portion, both shaped according to the desired edge seal. The hot blade is pressed against the stack to penetrate successive films, top to bottom. Thereafter, the blade represents a hot wall opposite to the parted edges of the film in the stack, causing transfer of heat into the stack for causing a controlled width of opposed films to become fused together. The time is not critical where the heat used is that which is stored in the cutter. The lateral surface of the blade extends from an edge, either perpendicular to the top surface of the stack or sloping away from the outline of the cut stack.The edge seal is ideally about 20% thicker than the combined thickness of the films forming a finished article, but it can be much thicker. The inner surfaces of a pair of films are face-to-face, well-suited to form a pressure-releasable valve in a spout of a container, especially a self-resealing valve.
