Abstract: The present invention is directed to pharmaceutically acceptable polymeric compositions suitable for injection molding of single or multi-component pharmaceutical dosage forms comprising a plurality of drug substance containing sub-units, being capsule compartments and/or solid sub-units comprising a solid matrix of a polymer which contains a drug substance, the sub-units being connected together in the assembled dosage form by a weld between parts of the assembled dosage form.

Abstract: A receival hopper for delicate and fragmentary particulate material such as fruit berries or bark pieces, in which the hopper (2) includes a support frame (5) with a receiving bin (3) pivotally secured to the frame (5) and an auger (4) which includes an auger screw (8), extending along a peripheral lip of the receiving bin at or adjacent the pivot, with a pair of adjacent but spaced hydraulic rams (6) secured between the bin and the support frame for moving the bin between lowered and raised positions relative to the support frame.

Abstract: On an automatically-steered cotton harvester, a sensor follows a crop row of cotton plants and sends a signal to a computer controller when the crop row changes its position relative to a row unit on the harvester. The computer controller calculates the amount of deviation between the crop row and the center of the row unit, and sends a control signal to a solenoid valve to actuate a hydraulic cylinder, or to a relay to actuate an electric motor, to laterally move the row unit along a tool bar on which it is mounted to more closely align the row unit with the crop row.

Abstract: The system has two units for transferring a telephone circuit from an old pair to a new pair between two locations. Each unit has a carrier amplitude measuring circuit to determine which location has the larger carrier amplitude and therefore which is the upstream location. Each unit has a charge switch, two transfer switches in the form of an old pair switch and a new pair switch and a controller for controlling the switches. One of the units closes its charge switch to charge the new pair to the dc level of the old pair. Then, the upstream unit operates its two transfer switches at the same time to switch from the old pair, by opening the old pair switch, to the new pair, by closing the new pair switch. The upstream unit transmits a signal to the downstream unit on a third pair. When the downstream unit receives the signal, it operates its two transfer switches at the same time to complete the transfer from the old pair to the new pair.

Abstract: A cable analyzer is capable of having a group of 25 pairs of wire from a telephone cable connected by a module to the analyzer. By a central processing unit or computer in the analyzer, a series of relays connect any one of the pair of wires to a routing board. At the routing board, a plurality of analog tests may be directed to be conducted upon the pair of wires and ground, or the wires may be routed within the analyzer for other purposes. The results of the analog tests are converted to binary digital format so that they may be analyzed by the central processing unit. The results are visually displayed or printed. The central processing unit has the capabilities, through different programs, to conduct a plurality of tests upon each pair, and upon the completion of the plurality of tests, proceed to a subsequent pair for a plurality of tests.
