Abstract: An apparatus disposed in a speedometer-odometer drive assembly for transferring and translating the rotation of a speedometer drive cable to a speedometer needle registering speed and an odometer registering distance, having a field cup disposed at one end of a drive shaft in communication with the speedometer cable and rotatable about a central axis with this shaft. The rim of the field cup is discontinuous at at least one point about its periphery by virtue of a cut or split being upset with respect to the radial plane of the surface of the field cup rim. These cut or split edges of the field cup rim act to engage successive threads or teeth on a gear means driving the odometer as the field cup rotates. A flux cup is inserted into the field cup to cover a magnet mounted within the field cup. The flux cup responds to the magnetic field created by the rotating magnet, thereby driving said speedometer. The gear means driving the odometer comprise a camming means fixedly mounted on a face gear.

Abstract: A freeze drying apparatus of the manifold type having a generally horizontal free standing condenser tube enclosed within a removable hollow manifold having a plurality of ports formed in it for communication with the interior of containers having specimens to be sublimated. The condenser tube is disposed generally along the central axis of the manifold so that the distance between the condensing surface and the manifold ports is relatively short and constant to provide fast and uniform sublimation. The condenser tube is packed with a woven copper mesh to provide increased surface area for wetting by the refrigerant fluid thereby increasing the condenser capacity and reducing its temperature. The location of the condenser tube within the manifold provides a single volume to be evacuated and speeds system recovery as new materials are added to the system.
