A conveyor assembly is provided for accumulating and discharging a column of evenly spaced items. The conveyor assembly includes a receiving conveyor, a discharge conveyor and a belt guiding carriage. The receiving and discharge conveyors each include a plurality of round belts that are interlaced with the receiving belts being at a slightly higher elevation on the receiving end of the system and the discharge belts being at a slightly higher elevation on the discharge end. Both sets of belts pass through a movable carriage that guides the receiving belts from the upper elevation to the lower elevation and the discharge belts from the lower elevation to the upper elevation so that the receiving belts are at a higher elevation on the receiving end of the carriage and the discharge belts are at a higher elevation on the discharge end of the carriage.

Conveyor assembly

A sensor device mountable on a threaded valve stem of an inflatable tire of a vehicle having an actuating pin adapted to be depressed by a component of an air gauge or a connecting fixture of a compressed air line, generally consisting of a housing defining a closed chamber, having a first threaded opening permitting such housing to be threaded onto the valve stem, and a second opening; an abutment pin disposed in the housing engageable with the actuating pin of the valve stem for depressing the actuating pin of the valve stem and thereby opening the valve stem when the housing is threaded onto the valve stem, providing an intercommunication of the interiors of the tire and the housing; a valve disposed in the second opening of the housing having an actuating pin adapted to be depressed by the component of an air gauge or connecting fixture of a compressed air line; a sensor mounted in the housing for sensing the pressure in the housing chamber; a microcontroller connected to the pressure sensor for receiving and processing signals therefrom corresponding to sensed pressures; and a transmitter mounted on the housing and coupled to the processor for transmitting processed signals corresponding to sensed pressures.

Tire condition monitoring system with improved sensor means

A system for displaying dynamic readings of a motor vehicle's tire pressure, temperature and tire ride efficiency comprises individual integrated units that are removably attached to each valve stem. Each unit comprises a pressure sensor and a temperature sensor coupled to a microcontroller which activates a transmitter/receiver set with a measured signal. The signal is received by a transmitter/receiver set in a passenger compartment mounted display which feeds a signal through a microcontroller to the display unit. In operation, theft prevention serial numbers of the remote sensors are entered in the display unit. Each individual sensor may then be queried sequentially with the appropriate serial number to provide a pressure and temperature reading for a particular tire as well as battery condition. The readings and warning signals are activated in the display unit.
