Abstract: A method and apparatus for rupturing refuse carrier bags to expose the potentially salvagable materials therein is disclosed. A transport tube is provided with an inlet end having an upper circumferential portion cut away to receive carrier bags placed therein and an outlet end having an opening for expelling the contents of the carrier bags. A screw impeller means is rotatably supported in the transport tube. Drive means are provided for rotating the screw impeller within the transport tube to advance the carrier bags from the inlet end toward the outlet end. A sleeve means is formed is about the screw impeller between the inlet end and outlet end of the transport tube. The sleeve is slightly larger in diameter than the screw impeller. The upper portions of the carrier bags engage the sleeve and are thereby prevented from being further advanced through the transport tube. The screw impeller then ruptures the carrier bag to expose the contents therein.

In a two blow process, a first amplifier is connected to the load sensor for amplifying the load sensor signals representing both blows in the forming process. A first gain control circuit is connected to the first amplifier for adjusting the amount of amplification to a first predetermined level. A logic control circuit is connected to the first amplifier for generating a first enabling signal during the first blow in the forming process and a second enabling signal during the second blow in the forming process. A second amplifier is connected to the first amplifier for amplifying the load sensor signals representing only the first blows in the forming process. A second gain control circuit is connected to the second amplifier for adjusting the amount of amplification to a second predetermined level.

Abstract: The present invention relates to a fuse loss indicating system for monitoring the condition of a plurality of fuses in an electric circuit. The indicating system includes a plurality of individual indicator circuits, one for each fuse to be monitored. Each indicator circuit includes an optical isolator for electrically isolating the indicator circuit from the monitored circuit. When a monitored fuse blows, the associated optical isolator triggers a flip flop to generate a fuse loss signal to cause a warning LED to light and alert an operator as to which fuse has blown. In its preferred embodiment, the fuse loss indicating system is utilized to monitor the fuses in an SCR motor bridge circuit. In this embodiment, the fuse loss system also generates a bridge disable signal when a fuse blows to cause a bridge lockout circuit to disable the gating signals to the SCR's, thereby disconnecting power from the motor.

Abstract: The present invention relates to a ventilator system which utilizes a control valve to assist an attendant in disconnecting a ventilator conduit circuit from a patient's endotracheal tube. Prior to the present invention, when a ventilator system was operated in certain modes, disconnection of the endotracheal tube from the ventilator circuit caused water which may have accumulated in the ventilator circuit to spray over the patient and/or attendant. In the present invention, a control valve is connected between the outlet of the ventilator circuit and the patient's endotracheal tube. Normally, the valve is maintained in the open position to permit air to be supplied to the patient. However, when it is desired to disconnect the ventilator circuit from the patient's endotracheal tube, the control valve can be manually closed immediately prior to disconnecting the ventilator circuit, thereby preventing the spraying of any accumulated water.

Abstract: A machine for making and filling packets has an intermittently fed sheet material which is recurrently severed into packet strips. These strips are successively pushed downwardly by a battery of filling tubes which shift vertically, bear against the sheet strip, and fold it into a vertical trough-shaped receptacle open at the top. After the filling tube battery has moved downwardly, sets of vertically spaced sealing or clamping jaws operate to effect laterally spaced side seals in an upper strip and conjointly create top seals in the lower or preceding sheet strip. Product is metered to the packet strips. The sealed packets are severed from the strip after the sealing operation. The filled packet has outwardly bowed side walls and the juncture of the bottom wall and the side walls will assume a line, the configuration of which is a function of the size and cross-sectional configuration of the filling tubes, providing a unique advantageous form.
