Abstract: The apparatus includes a generally circular table having a fence about its periphery, and is provided with a conveyor for feeding quantities of container crowns onto the table. The table is rotated so that the container crowns are moved outwardly against the fence and fed centrifugally into a twist chute for receiving the crowns. The apparatus is provided with first and second curved channels coupled for conveying containers out of the twist chutes, the second curved channel merging together with the first channel at a point along their respective paths, with the path length of the first channel being substantially longer than that of the second channel between the twist tube, twist chute and the merging point. The apparatus includes the escapement assembly, the speed of which is controlled and is operated at the merging point for controlling the rate of movement of container crowns out of the first and second channels.

Abstract: A solar prominence adapter comprises a tubular housing having a first end adapted for connection with the eyepiece holder of a conventional reflecting or refracting telescope and the other end for connection with a conventional eyepiece. The housing includes an occulting disc positioned in a first plane for eclipsing or occulting an image of the sun present in that plane. A focusing system is provided for focusing the occulted image onto a second focal plane in which the image may be viewed by means of the conventional eyepiece. Supported in the housing is a prism for attenuating the solar radiation which is directed into the housing by the telescope when the adapter and telescope are connected. The housing may further include a filter for filtering out all but a narrow bandwidth of solar radiation and an adjustable diaphragm for varying the intensity of the observed image.

Abstract: A hopper is constructed to control the rapid, uniform and constant flow of disk-like objects, more particularly bottle crowns. The hopper employs a reservoir and means for feeding the disk-like objects to the reservoir. An electric eye responsive to the level of disk-like objects in the reservoir is connected to the feeding means to maintain a predetermined level of the objects in the reservoir. A conveyor is positioned to adjoin the reservoir to remove and deliver the disk-like objects at a uniform rate to the point of use of the hoppered objects.If the disk-like objects are asymmetrical, an orienting device is provided between the feeding means and the reservoir to orient the objects as they are delivered to the reservoir.

Abstract: In an astronomical telescope assembly which can be used in a non-observatory type building, a refracting telescope is mounted for rotation about its optical axis with the optical axis parallel to the axis of earth's rotation and with the eyepiece end of the telescope higher than the objective end, which extends to the outside of the building through an opening in a wall of the building. A reflector unit carried by the objective end of the telescope has a reflecting surface which is pivotable about an axis perpendicular to the optical axis for directing light into the telescope, the reflecting surface being manually positionable about its axis by control means provided at the eyepiece end of the telescope. The telescope proper may be of known construction or may employ spars upon which various optical elements can be releasably mounted for forming different optical systems. Automatic solar tracking apparatus is provided.
