Abstract: Aspects of the present disclosure relate to a warming system including a warming device. The warming device includes a clinical garment comprising a body portion adapted to cover a portion of a patient, an inner surface for facing the patient, and an outer surface for facing away from the patient. The body portion includes sleeves sized and positioned for receiving the patient's arms and a torso portion adapted to cover an anterior torso of a patient. A first pneumatic convective device can be disposed adjacent to the inner surface of the clinical garment. The pneumatic convective device can include an opening formed in the clinical garment for admitting a stream of pressurized, warmed air into the first pneumatic convective device. The warming system can also have a second pneumatic convective device in a fully-folded configuration or partially-folded configuration and disposed on a portion of the clinical garment.

Abstract: A control mechanism for controlling the flow of a particulate material through a conduit and comprises a bladder mounted within the conduit that is inflatable between a first, deflated state and a second, inflated state. In its first, deflated state the bladder allows the particulate material to flow freely through the conduit, and in its second, inflated state the conduit is substantially blocked by the inflated bladder and no particulate material may pass. An alternate embodiment of an exteriorly mounted control mechanism comprises a stopper that is moved between a first, open position away from an open end of the conduit and a second, closed position in which the stopper is in sealing contact with end of the conduit.

Abstract: An integrated and compact bag filling machine comprising a material dispensing spout, a slip tube suspended in substantially vertical alignment with the spout, and a bag sealing apparatus comprising a pair of opposable forming bars and a pair of independently actuable and opposable sealing bars is herein disclosed. The bag filling machine is capable of bottom filling and sealing both paper and plastic bags having gusseted or flat sides with little or no modification.

Abstract: A bag filling machine of the type having a discharge spout with clamps to hold a bag mouth on the spout is disclosed as incorporating gusset pleat gripping assemblies on opposite sides of the spout. Each of those assemblies has a pair of cooperatively actuable gusset gripping members operable between open and closed positions to selectively and independently grip each of the two gusset pleats on opposite sides of a gusseted bag and to pull those pleats apart to fully open positions. This increases the effective, material-receiving area of the bag mouth as it is opened with the opening of the spout to dispense granular material into the bag. A gusset tucker is also utilized on each side of the discharge spout in cooperative juxtaposition to the gusset pleat gripping assemblies. The gusset tuckers are moved inwardly towards each other and towards the bag to engage in the fold between the two gusset pleats on each side of the bag as the bag top is flattened to a closed position after being filled on a spout.

Abstract: A bag filling machine comprising a supply hopper, a material flow control mechanism and a rotatable bag filling spout is herein disclosed. The rotating bag filling spout is constructed and arranged for rotation about a vertical axis and is connected to the supply hopper through the material flow control mechanism so as to convey bulk commodities stored in the supply hopper into a bag that is to be filled. After the bag has been filled, the rotatable bag filling spout rotates to close the bag. A sealing mechanism is also provided to seal the filled bags once they have been closed by the rotating bag filling spout.

Abstract: A device for topping-off a substantially filled bag with a final charge of particulate material to provide a predetermined final charge weight in the bag is herein disclosed. The device comprises a lower frame supported upon a plurality of load cells and an upper frame supported above the lower frame also upon a plurality of load cells. The upper frame has rotatably suspended therefrom a pair of carriage assemblies which support respective housings. Each of the housings has disposed therein a belt capable of linear motion. The belts are exposed on an inner face of each of the housings such that when the carriage assemblies are rotated toward one another, the respective belts meet one another and are able to engage the opposed faces of a bag. A plurality of bag grasping means are mounted upon the respective housings so as to be able to grasp and hold the opposed faces of the bag received between the belts to open the bag as the housings are rotated away from one another.

Abstract: A fully automated apparatus and operating system for supplying, transferring, filling, and sealing bags, utilizing a clam shell type of filling spout is provided in combination with apparatus for sealing each filled bag in close proximity to the spout. The bag sealing apparatus incorporates heat sealing bars mounted on a carriage movable between a first position adjacent to the filling spout for receiving filled bags and sealing them, and a second position wherein filled and sealed bags are released. The same carriage supports clamping bars movable between open and closed positions to clamp a filled bag while it is still being held on the filling spout, and to support the bag, after removal from the spout, while the bag mouth is being sealed by the heat sealing bars.

Abstract: A precast concrete soil retaining structure is provided comprising an upright portion, a base portion, and a plurality of retaining caps. Preferably its use will be as a wingwall for use with culvert systems. The upright portion of the structure has a first face and a second face, as well as a first end and a second end. The first end is of a height greater than or equal to the height of the second end. The base portion has a top surface and a bottom surface and a plurality of channels of a first diameter, each of which extends between the top surface and the bottom surface. Each of the retaining caps has a channel of a second diameter extending therethrough, with the second diameter preferably being less than that of the first diameter. Each of the retaining caps is positioned above a respective one of the base portion channels.

Abstract: A high speed bag filling machine utilizing a tiltable spout for attaching a bag in a tilted position and reversing the tilting motor to move the spout and bag over a conveyor. A vertically movable transfer carriage comprises a front forming bar and a pair of horizontally rotatable rotor arms. The bar and rotors clamp the filled bag, lower it to a conveyor, and discharge it. The forming bar then swings forward and upward to clear the rotor arms, which rotate forwardly beneath it to permit the next bag to enter the clamping area. The forming bar then swings down to engage the front face of the bag and the rotor arms continue their rotation to engage the rear face of the bag. The forming bar and rotor arms may include endless belts driven to discharge the bag.
