Abstract: CAM CONTROLLED SWITCHING MEANS FOR ICE MAKER            Abstract of the Disclosure An automatic ice maker mechanism includes a face cam on a timing motor driven disc formed with a plurality of con-centric cam tracks.  The disc is supported on one side of a circuit board, said board having a plurality of flexible blade switches cantilever supported on its other side.  The mechanism further includes a plurality of slidable cam follower plunger pins each of which is contacted by an associated blade switch such that each pin is biased into spaced follower relation with one of the cam tracks.  In operation the circuit board control circuit interconnects ice maker cycling means with the motor to initiate rotation of the disc whereby the cam track profile effects predetermined movement of its associated pin in one direction causing the contact on an associated blade switch to open with its stationary contact.  Continued rotation of the disc results in the blade switch moving its follower pin in the opposite direction reclosing the contacts such that selected functions of the ice maker are performed in a predetermined sequence.

Abstract: ABSTRACT OF THE DISCLOSURE       An improved locking system for a vending machine of the type comprising a plurality of vertical maga-zines each consisting of an endless belt having a plurality of spaced trays thereon.  A receiving tray mounted below each of the belts has a lock lever associated therewith.  The lock lever is normally biased into a first position which prevents unauthorized rotation of the receiving tray to prevent the dispen-sing of a product held thereon.  Rotation of the endless belt forward causes one of the trays thereon to engage the lock lever to move it to a second position to unlock the receiving tray and thereafter engages the receiving tray to pivot such tray to a dispensing position.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for mounting a rotatable component on a rotating shaft using a non-machined torque transmitting intermediate hub member is disclosed. The hub member makes torque transmitting contact with the drive shaft and transmits that torque to the rotatable component through frictional contact at a taper on the drive shaft and at a recessed shoulder of the hub as well as by an external key on the hub periphery and a matching cut-out formed in the rotatable member.  There is also a keyway and key between the drive shaft and hub for accurate alignment in assembly and disassembly.  A plurality of narrow longitudinally extending rib members are integral with and are supported on the other peripheral surface of the hub member whereby the rotatable member when it is seated against the shoulder on the hub member for the first time mechanically distorts the rib members from their original shape to provide a secure but releasable fit between the hub member and the rotatable component.  A nut and washer assembly secure the rotatable component and hub member to the drive shaft.

C-field means in the improved molecular beam tube-apparatus for producing a weak magnetic field comprise a conductor in-cluding a plurality of equally spaced helical turns forming a generally closed loop lying generally in a beam plate including the path of the beam. The loop including two end sections transverse to the beam path and parallel to one another, each of the end sections including a beam aperture having first and second opposed edges interrupting the conductor in at least two adjacent helical turns to provide two internal ends adjacent each of the opposed beam aperture edges.  There are at least two conducting jumpers adjacent a beau aperture, each said jumper having a first jumper end connect-ed to the helical turn internal end adjacent the first aperture edge, and a second jumper end connected to the internal end of the same helical turn adjacent the opposed second edge, whereby the conductor provides a continuous conducting path through the helical turns and the jumpers around said beam apertures, and the magnetic field adjacent an aperture has greater strength than at other portions of the loop.

A lid is sealed to the can immediately after the head space has been filled with steam or the inert gas, and the lid is crimped to the can.  An apparatus for replacing gases during canning process is also disclosed.         By these method and apparatus the gases in the head space of the can can be easily and unfailingly replaced with steam or the inert gas.

Abstract: GASTROINTESTINAL SCANNING AGENT                      Abstract Technetium-99m has ideal characteristics for im-aging the upper and lower GI tract and determining stomach emptying and intestinal transit time when used with an insoluble particulate material.  For example, crystalline and amorphous calcium phosphate particles can be effectively labeled in a one-step process using 99mTcO4 and SnC12. These labeled particles have insignificant mass and when administered orally pass through the GI tract unchanged, without affecting the handling and density of the in-testinal contents.  Visualization of the esophageal entry into the stomach, -the greater and lesser curvatures of the stomach, ejection into the duodenum, and rates of passage through the upper and lower GI tract are obtained.  The slurry of 99mTc particulate can be given rectally by enema.  Good images of the cecum and the ascending, transverse, and descending colon are obtained.  Mucusal folds and the splenic and hepatic flexures are visualized The resilience of the large intestine is also readily visualized by pneumocolonographic techniques.
