Patent number: 4632022Abstract: A fume hood is fabricated of three or four like modules to a desired partial or full cylindrical structure having a reaction chamber therein. Each module has an upstanding, arcuate circumferential outer wall and an upper wall and base extending inwardly therefrom in coincidence above and below one another. The top wall and base have the shape of a sector of a circle with their apexes opposite the outer wall and the outer wall being the arc of the sector. An inner wall spaced interior of the outer wall defines an exhaust passageway therebetween with movement of gases and air being through exhaust ports through the inner wall. The exhaust ports are spaced apart between the top wall and base and are at constant certain distances from the top wall and base.Type: GrantFiled: February 25, 1985Date of Patent: December 30, 1986Assignee: St. Charles Manufacturing Co.Inventors: William E.

Patent number: 4568050Abstract: A unique component furniture assembly for securing furniture components in wall furniture systems comprises a light-weight metal track, along which glides a novel fastening assembly which receives screws, threaded support posts and the like and to which a given furniture component is secured. The fastening assembly includes a block, preferably a plastic nut, carried by a basket. The block is suspended within the basket by a coil spring or other bias means. Relative expansion of the block and the basket by action of the spring causing contact with inner surfaces of the track causing the fastening assembly to remain stationary, though moveable on the track. The present furniture assembly further includes a plurality of selectively spaced detents, preferably raised protuberances, on the inside bottom surface of the track which function to lock the fastening assembly to the track and are used to align fastening assemblies on adjacent and opposing tracks.Type: GrantFiled: November 25, 1983Date of Patent: February 4, 1986Assignee: St. Charles Manufacturing Co.Inventors: Paul D. Radoy, Walter R. Deshaw, William A. Peacock

Patent number: 4474288Abstract: A check-out counter assembly includes a cabinet that has an open space with guide rails located adjacent opposite edges of the space to receive a conveyor module which is completely self-contained and includes a power source as well as all of the removable components of the conveyor system. In addition, the respective rollers which support a conveyor belt are also designed as modular units which can be removed from the frame without any special tools. The conveyor module is designed so that power is automatically interrupted when the module is removed from the cabinet and the cabinet also has a safety plate which automatically interrupts the electric motor when an obstruction enters the space between the surface of the moving conveyor belt and the adjacent fixed surface of the cabinet.Type: GrantFiled: September 2, 1981Date of Patent: October 2, 1984Assignee: St. Charles Manufacturing Co.Inventor: Stanley J.
