Abstract: A combination air and ground source heating and/or cooling system. The system includes an indoor unit, an outdoor unit and an in-ground unit, each of which has a coil, an inlet line and an outlet line. The system also comprises a flow connector, a coupling and a controller. The controller is configured to control the flow connector and coupling so that the system is selectively operable in three different modes. In the first mode, refrigerant bypasses the coil of the outdoor unit, while, in the second mode, refrigerant bypasses the coil of the in-ground unit. In the third mode, refrigerant flows through the coils of the in-ground and outdoor units.

Abstract: A method for the preparation of a ketone from a narcotic alkaloid having an allyl alcohol moiety is disclosed. The method includes mixing the narcotic alkaloid with an acid in the presence of a catalyst wherein the method is carried out in the substantial absence of hydrogen gas. The method is useful for preparing hydromorphone and hydrocodone compositions having novel impurity profiles. Compositions comprising hydromorphone and hydrocodone are also disclosed.

Abstract: Novel formulations useful for thyroid hormone replacement and suppression therapy are described herein. While dosage formulations containing iodinated thyronines, levothyroxine sodium (T4) or liothyronine sodium (T3), as the active pharmaceutical ingredient (API) dispersed in a polymeric solid are known, manufacturing such formulations with acceptable dose content uniformity is difficult due to the high biological activity of T4 and T3. Described herein is the preparation of a single API formulation containing both T4 and T3 in a pharmaceutically effective ratio, wherein the dose content uniformity is the same for T3 as for T4 even if the T3 dose is extremely low.

Abstract: A method and device for controlling the operation of a heat pump having a primary heat system and an auxiliary heat system, and used to heat air circulating in an enclosure such as a building, the invention comprising a first sensor positioned in the return duct of the heating system for measuring the temperature of air being returned to the heat system from the enclosure, a second sensor for measuring the temperature of air which has been heated only by the primary heat system, a temperature comparing relay for comparing the two sensed temperatures and determining the difference between them and actuating the auxiliary heat system only when the temperature difference is less than a predetermined set point, for example 4° F., thereby providing a significantly enhanced operating efficiency of the heating system.

Abstract: A collapsible container of for example a thermoplastic material comprises a bottom 10, side walls 11 and end walls 13. The side walls and bottom are made up of regions interconnected by fold lines 15 and 16, enabling the container to be folded flat and then folded on itself to provide a compact article. The side walls may be attached to the end walls by flaps 17 provided with press studs 18. Handles 22 and 23 for carrying the erect container may be provided in the side and end walls, and a handle 20 for carrying the collapsed container may be attached to the bottom by portions 21 of the handle engaged in slots in the bottom.

Abstract: The present invention relates to the fabrication of boat hulls and other three-dimensional objects of thermoplastic sheet material. The process comprises heating a sheet of the material along a predetermined pattern of lines to a temperature at which the material is softened, placing the sheet in a jig with the material of the sheet still soft along the heated lines and folding it along the softened lines, and retaining the sheet in its folded state in the jig until the material along the said lines is cool and stiffens. The preferred thermoplastic material is polypropylene, and by reversely folding the sheet along selected fold lines an integral hinge can be induced. In making a foldable boat, the pattern of fold lines is such that the sheet in its folded state has the shape of the hull of a boat. A blank when so prepared can be rolled into extremely compact form for transportation and to erect the hull is merely unrolled and with a little manual assistance put into the required shape and secured.

Abstract: An apparatus is disclosed for the continuous manufacture of fiber reinforced plaster sheets which apparatus includes a conveyer for supporting a plurality of sheet casting moulds, a casting station for casting slurry into said moulds and a fiber station at which means are provided for depositing fiber for reinforcement across the surface of the casting slurry. The apparatus also includes a pair of rollers having radial extensions to force the fibers to or adjacent the lower surface of the cast slurry. A second fiber depositing means is also provided for depositing a second batch of reinforcing fibers across the surface of the slurry and a second pair of rollers having an open mesh surface are provided for forcing the second batch of fibers into the slurry to a level at or adjacent the upper surface thereof. The fibers used may be sisal or fiberglas as individual randomly oriented lengths, continuous meandering strands or a random mat deposited over the surface of the slurry.
