Abstract: A file includes a support member having an abrasive surface treated with a sanitizing agent. The surface or the interstices between particles of abrasive hold the sanitizing agent which is released with use of the file. The sanitizing agent is either in a liquid carrier or contained within microcapsules. The microcapsules are frangible and break upon use of the file to release the sanitizing agent. The file surface may comprise granular abrasive particulates having a size ranging from 40 to 1200 grit which provide the interstices between at least some of the particulates. An aqueous coating having dispersed therein an adhesive and the microcapsules is applied to the granular particulates. The coating is dried to deposit in the interstices the microcapsules. The adhesive binds the microcapsules to the granular particulates. When a mixture of sanitizing agent and liquid carrier is used, the abrasive surface is coated with the mixture and then the carrier is removed to coat the surface with the sanitizing agent.
Abstract: A dual-chamber syringe has a plunger within an inner delivery chamber in fluid communication with an ejection port. The deliver chamber is formed within a tubular element axially slidable within a tubular guide. The tubular guide and the syringe outer barrel form an outer reservoir chamber. The outer reservoir chamber is sealed from the delivery chamber while the tubular element is in a first position within the guide. Upon withdrawal of the plunger, frictional contact imparted by the plunger seal causes the tubular element to slide away from sealing engagement with the barrel into a second position within the guide. In the second position of the tubular element, a fluid passageway is opened from the reservoir to the delivery chamber allowing fluid to be drawn into the delivery chamber. A porous seal between the plunger rod and barrel allows air into the reservoir during transfer of fluid to the delivery chamber.
Abstract: Adjustable pliers for a constant tension hose clamp include a pair of arms pivotally connected together at intermediate portions of the arms. Each arm has a handle portion and a gripping portion, and the gripping portions have opposed ends that are spaced apart a predetermined distance. Each end has a grasping element, with each grasping element adapted to hold one actuating member of the hose clamp. This enables the hose clamp to be held by the grasping elements between the gripping portions to enlarge the diameter of the hose clamp by pressing the handle portions together. One of the arms has two separate sections, a gripper section and a handle section. These sections are rigidly connected together by an adjustable rod mechanism that enables the two sections to be moved relative to each other to change the angular relationship between the two sections by adjustment of the rod mechanism.

Abstract: A conveyor indexing mechanism for a bakery production line includes a variable speed motor, a conveyor, a number of baking pans, a dough packet drop mechanism, a sensor, and a timing generator. The conveyor moves the baking pans under the dough packet drop mechanism at a base speed and a ramp-up speed based on input from the sensor and timing generator. The sensor senses pan pockets in the baking pans which causes the motor to assume the base speed. The timing generator periodically causes the motor to assume the ramp-up speed. The indexing mechanism ensures that a row of pan pockets will be below the dough packet drop mechanism so that a row of dough packets will consistently fall therein with maximum throughput. The absence of any clutch or brake reduces wear, as does the continuous motion of the drive train, which prevents backlash in the gear components. A programmable controller receives system inputs and instructs an inverter to change the motor speed.

Abstract: A novel irrigation valve having a single central inlet and a plurality of radially located outlets each covered by a sliding disk valve. Each disk valve is manually operable and in automatic mode is operated by the interference action of an innovative indexing mechanism which uses the hydraulic pressure of the inlet for its operation a single three-way solenoid valve is energized to actuate a piston within the indexing mechanism while a pin-teeth engagement of a cylinder-indexer assembly converts the linear motion of a piston rod into a rotary motion of an indexing arm. A battery operated timer controls the time intervals between each incremental rotation of an indexing arm in sequence until it is returned to its home position. The housing of the valve is compact and of low profile, thereby simplifying its manufacturing, assembling, installation and maintenance and reducing cost.
