摘要： A microfiche viewer with a light projection path whereby different images on an individual piece of microfilm can be placed in the light projection path for viewing. The fiche is rectangular in configuration and is inserted into the viewer with the shorter side parallel to the front of the viewer. A rotatable base is attached to the bottom of the viewer which is designed to limit the angular rotation of the microfiche viewer.

摘要： An image focusing apparatus for microfiche film readers and other optical systems has a lens holding apparatus which rests on a transparent or glass plate, a rotatable lens adjusting assembly in the lens holding apparatus, a shaft slidably and pivotally connected to the lens adjusting assembly, a knob on the shaft, and a shaft holder which fixes the position of the shaft with respect to the reader. The lens holding apparatus is universally mounted to the frame of the reader to enable the lens holding apparatus to move freely in response to changes in the angular disposition of the glass plate with respect to the horizontal plane. The lens adjusting assembly has an eccentric finger which translates the rotating motion of the knob and shaft into a vertical force, which moves the lens. The lens adjusting assembly has a barrel, a socket in the barrel and key slots along the socket. The shaft has a partially-spherical end and keys which slidably and pivotally fit into the socket and key slots. The simultaneous slidable and pivotal operative connection of the shaft to the lens adjusting assembly enables the operator to adjust the lens regardless of the angular disposition of the lens adjusting assembly with respect to the shaft. The connection also enables the lens holding apparatus to move freely in response to changes in the attitude of the glass plate with respect to the lens.

摘要： A lamp assembly and power module is provided for a microform display apparatus, such as a fanless microfiche reader. The lamp assembly and power module are both situated in a drawer which is removably inserted into the base of the reader to form a air-restricted path for the efficient convection of heat away from the reader. By setting the lamp at an angle to the longitudinal axis of the drawer, both the lamp assembly and power module components can fit in the drawer. The front end of the drawer is provided with a grille for air passage, and a chimney structure is situated adjacent the rear of the drawer for the efficient evacuation of heat. The lamp and power module are located below the chimney, and as the lamp and power module components heat the surrounding air, the air rises up the chimney and out of the reader by convection. This air movement creates a draft through the grille in the front of the drawer, which serves to sufficiently cool the components.

摘要： A trolley rail system (10) for supporting and guiding a sliding cooler door (14) of a walk-in type cooler. The system has a guide rail (27) having two linear segments (29,30) and two deviation ramp portions (33,34), and an auxiliary rail (38). The system also has a leading trolley (41) and a trailing trolley (42). The leading trolley has a wheel (51) supported upon the guide rail. The trailing trolley has a primary wheel (52) supportable upon the guide rail and an auxiliary wheel (53) supportable upon the auxiliary rail.
