An ultraviolet lamp assembly includes an elongate lamp bulb, a central reflector mounted above the bulb and side reflector panels mounted on opposite sides of the central reflector panel. A first air gap is located between the first side reflector panel and the central reflector panel when the first and second side reflector panels are in the open position. A second air gap is located between the second side reflector panel and the central reflector panel when the first and second side reflector panels are in the open position. An air moving device is configured to direct cooling air downwardly through the perforations at the upper portion of the bulb and downwardly through the first and second air gaps at the lower portion of the bulb.

Shuttered lamp assembly and method of cooling the lamp assembly

An exhaust system for use with a microwave excited ultraviolet lamp system is provided to receive cooling air emitted from the lamp system and to contain and direct the cooling air so as not to contact a substrate being irradiated with ultraviolet light. A lens, such as a quartz lens, is supported by the exhaust duct to transmit the ultraviolet light emitted from the lamp system toward the substrate.

Exhaust system for a microwave excited ultraviolet lamp

A system for monitoring the flow rate of particulate material entrained within an air stream includes a feed hopper providng a source of the particulate material, and a hose for conveying the particulate material within the air stream. A pump draws the particulate material from the feed hopper and transports the particulate material with the air stream through the hose. A flow meter is associated with the hose and measures the mass flow rate of the particulate material through the hose to provide a first flow indication. A device is associated with the feed hopper and measures the change in weight of the feed hopper over a predetermined interval to provide a second flow indication. A controller corrects the first flow indication from the flow meter according to the second flow indication from the gravimetric device. The flow measurement system provides an accurate and fast responding flow meter by combining the advantages of a fast responding in-line flow meter with the accuracy of a weight measurement system.

Apparatus for dispensing a mixture of two components comprises a dispenser device formed with a first passageway connected to a source of a Component A material, and a second passageway connected to a source of a Component B material, both of which are connected to a static mixer where the components are combined to form a mixture. The dispenser includes structure for purging the mixture of Component A and B from areas of the dispenser which come into contact therewith, and a check valve operative to create a suction within the dispenser and static mixer to prevent leakage of the mixture from the static mixer when flow of the components is interrupted.

Two-component dispensing system

In an apparatus and method for measuring the strength of an adhesive bond, a dispenser applies adhesive to a substrate for a prescribed period of time, a conveyor moves the substrate to a compressing station within a preselected open time, after which time a compressor compresses the substrate against another substrate to form an adhesive bond therebetween, the bond being formed under a substantially constant compression force and for a preselected compression time. During the latter portion of the compression time, the bonded substrates are moved together at a substantially constant rate of speed through a transition distance, one of the substrates contacting a stop plate at the end of the compression time to prevent further movement while the other of the substrates continues at the substantially costant rate of speed to break the bond. A load cell measures the maximum pull force required to break the bond and also provides a real time analog signal for the pull force of the bond during tension, thereby to obtain an indication of the total energy expended in breaking the bond.

Method and apparatus for bond testing

A work-performing manipulator robot having a base, a turret rotatable on the base about a vertical axis, a vertical arm rotatably mounted on the turret for rotation about a horizontal axis at a shoulder joint, and a horizontal arm rotatably mounted on the vertical arm for rotation about a horizontal axis at an elbow joint. The mounting of and angular position transducer for the turret/base joint is such that electrical cables and hydraulic fluid hoses can be coupled through apertures in the turret and the base to a channel in the vertical arm. The vertical arm is driven by a cylinder/piston assembly wherein the cylinder is pivotally attached to the vertical arm and the rod is pivotally attached to the turret, reducing the relative travel between the cylinder and the vertical arm. A servo valve for each of the armactuating cylinders is mounted on the side of the vertical arm and pivotally attached to the arm about the same pivot point as the associated cylinder so that the servo valve and the cylinder may be coupled together by rigid fluid conduits without relative movement between the servo valve and the cylinder.
