Each loadlock chamber includes a refrigerated platen that projects into the loadlock chamber, a heat lamp assembly that radiates into the loadlock chamber, and a tray for holding the wafer therein. The platen has a cooling system for selectively cooling the wafer, and selective radiation of the heat lamp assembly degasses the wafer.

Abstract: The present invention provides a small, simple and easy-to-use elevation checking and measuring device that can also be used to measure points to the same level as a known point. The invention comprises a primary housing and secondary casing which contain tape measuring blades. The primary housing has opposing sidewalls each of which may include a vertical slot. The slots are designed to mate with projections extending from the secondary casing. The slots and projections provide alternative angular orientations of the housing and casing when connected together. The primary housing contains level indicators to determine when it is held level. It also includes a light source that illuminates a target at the end of the primary housing blade. Maintaining the beam on the target while using the level indicators to achieve a horizontal orientation of the primary assembly, thereby permits a user to make quick and accurate grade or height measurements with the tape measure blades.

Abstract: A housing is provided which attaches to a wall and includes mechanisms for releasable attachment to a wall hanging such as a calendar. The housing may have a decorative facade and includes a depressible button which operates through a spring biased J-shaped rod or flexible strips to move a clasp member out of an elongated slot in the bottom of the housing. The slot accommodates an edge portion of a wall hanging. Securement occurs when the button is released and the spring bias or inherent flexibility of the strip member frictionally engage the wall hanging edge. Alternatively, the wall hanging edge may include an engagement aperture. In such case, the clasp member will pass through the aperture and suspend the wall hanging in the housing slot.

The condenser unit includes a condenser coil section which may be wrapped with ambient water for producing a supply of hot water.

Abstract: An outdoor portable grill is provided having a cooking assembly comprising a food support, a handle for the food support and a handle holder interconnecting the food support with the handle. A support assembly is also provided comprising a upstanding slider post extending from an attachment bracket. The attachment bracket is used to secure the post to an outdoor heat source fixture such as a campground grill or fire pit ring. The handle holder is provided with an engagement opening having multiple inner edges that engage corresponding surfaces on the slider post. The weight of the food support causes the edges to frictionally engage the post exterior. This action allows the food support to be locked into an infinite variety of vertical and radial positions. The handle is pivotally attached to the handle holder for enabling the handle to be rotated against the food support for compact storage.

Abstract: A multi-purpose tool housing is provided having an implement that is rotatably stowable in an individual housing opening. The opening includes a separate lock plate that engages the end surfaces of a pivot plate that extends from an inner end portion of the implement. The end surfaces are angularly oriented to permit the lock plate to not only secure the implement in a storage mode, but also secure the implement in predetermined angular orientations for convenience of use. A spring biased plunger, flexible bands and spring members operate between the housing and implement to automatically move a portion of the implement out of the housing opening to a predetermined access orientation. Thereafter, a user may readily grasp the implement and rotate it to the desired use position. When scissors are being used with a flex strip between the scissors handles, a bumper part coacts with the lock plate to hold the handles together for storage against the flexural bias of the flex strip.

Abstract: A dispenser for dispensing an alcohol-glycerine disinfecting gel or liquid for use by doctors and nurses. The dispenser consists of a main housing which mounts a pumping mechanism for pumping out an alcohol-glycerine disinfecting gel from a replaceable, disposable supply-cartridge releasably mounted in the main housing. Since the main housing is small enough to fit within a person's hand, the doctor or nurse may dispense the contents of an alcohol-glycerine disinfecting gel simply by squeezing the two parts together. The dispensing of the gel is applied directly onto the fingers of the same hand that has squeezed the main housing to have caused such dispensing to occur. Owing to the small size of the main housing, the dispenser of the invention may be worn on-the-person, such as by the waist-belt.

Abstract: A quick release connector system is provided for interconnecting a frequently used portable accessory item with a support body. The system utilizes a clasp having a back wall spaced apart from a stationary wall. The stationary wall includes an enlarged opening from which extends a slot. A deflectable wall overlies the enlarged opening. A connector part forms the quick release connection with the clasp. It is attached to the portable accessory item via a post with an enlarged head. The post has a diameter less than the width of the slot and the head has a diameter greater than the width of the slot, but less than the enlarged opening. When the deflectable wall is flexed away from the enlarged opening, the head of the connector part will pass through the opening and slide behind the slot as the post is moved into the slot. The enlarged head behind the slot will prevent axial disengagement.

Fitted within the channels are preformed static mixing units to provide additional mixing action.

Abstract: A compact flashlight is provided having a base with an interior recess for permitting reciprocable movement of a disk battery. The base includes a bulb having a first lead that extends along the bottom of the interior recess. A second diverging lead extends from the bulb to an area along an upper side of the recess. The battery overlies the first lead so that electrical contact is made with the bottom portion of the battery. A carrier overlies the battery and includes a boss portion extending into an opening of a cover that encloses the base. Forward thumb pressure on the boss portion moves the battery from a bulb-off to a bulb-on position when the battery comes into electrical contact with the second diverging lead. This results in illumination of the bulb. The carrier is provided with resilient members extending outwardly from the back end of the carrier. The resilient members engage a corresponding detent in the housing and maintain the battery in an off position.
