Free flowing, substantially dust-free, dense granular amorphous precipitated silica having a principal particle size of between about 0.14 mil- limeters and about 0.84 millimeters are described. This material is particularly suitable as an inert carrier for water-soluble and fat soluble nutritional supplements, e.g., vitamins, which are added to feeds for livestock.

Christopher P Amberg assigned to Fort Howard Cup Corporation

The present invention relates to a carrying tray and, more particularly, to a tray which securely holds hot and cold drink cups of various sizes, and is adaptable to hold other items. A plurality of gripping elements in a cup receiving cavity grip and retain a chime-bottomed cup. A fiat- bottomed cup is stably supported on a platform in the cup receiving cavity. Various inserts may be selectively used to more stably retain tall cups or to retain other items, such as ice cream cones and the like.

P U L L TAB O P E N E R

Robert Chagoya

A pull tab opener for use on pop-top cans such as are used for beverages having a mounting with fingers gripping the edge of the can opposite the pull tab and a lever arm hinged to the mounting for rotation downward and over the pull tab. The arm has a lip which falls below the periphery of the tab, when the tab is pushed down. When the arm is raised, the lip raises the pull tab above its yield point, but less than that which would break the seal at the opening. Thereafter the can is storable and can be readily opened by the fingers. A yieldably resilient portion of the lever arm is held against the opening in the can by an extension releasably engaging the edge of the can opposite the edge gripped by the fingers.

A beverage dispensing machine which combines a powdered beverage mix and water in a first mixing chamber, provides for additional disper- sion and solubilization of the powder in water in one or more additional mixing chambers and thereafter gravity feeds the powder-containing liquid into a low-capacity reservoir from which the beverage may be dispensed on an intermit- tent basis.

A beverage can is provided with a tab having opening and sealing portions. The tab is riveted to the can lid in a central portion thereof with the opening portion being adjacent an openable area of the can lid which is defined by a continuous score line. The can is opened by lifting the sealing portion of the tab which causes downward movement of the opening portion which in turn impinges upon the openable area of the lid until an opening is formed. After forming the opening, the tab is rotated 180 degrees until the sealing recoverable portion is juxtaposed over

the opening, thus covering the opening to keep out foreign matter. The tab is then pushed down- wardly so that the sealing portion is fitted into the opening, thereby affecting a seal.

EXERCISER WITH BEVERAGE RESERVOIR

Hy S Gordon assigned to Hydrocizer Industries Inc

A dumbbell-shaped hand held exerciser has a tubular central section formed as a drink reser- voir and screw-on end caps of different weights enabling the overall weight of the device to be varied dependent on the end caps selected for use with the central section. The central section may include a drinking valve and the device has a U- shaped handle member with a removable mois- ture absorbent cover.

A can filling device for minimizing damage to cans during filling by providing full can pockets on a filler wheel having upper and lower arm portions which maintain the constant vertical orientation of the can during the filling process. A locator brush is disposed to induce an inward radial force relative to the rotating filler wheel to maintain the can within the can pocket. Addi- tionally, a hold down guide assembly displaces the cans in a downward position on the rotating filler wheel to prevent damage by the spindle mechanism. Sufficient tangential clearance is provided by the star wheel pockets to prevent damage due to play between the rotating filler wheel and the star wheel. Close tolerances are provided in the radial direction to ensure full transfer of the can from the star wheel pocket to the filler wheel pocket.

Nobuo Shimomura, Nagoya, Japan assigned to Kabushiki Kaisha Toshiba

A siphon coffee maker consists of a lower con- tainer into which water is poured and which is heated with an electric heater, an upper con- tainer for containing coffee powder, the upper container communicating with the lower con- tainer so that hot water is transferred between the containers through a water feed tube due to siphon effects, and a pressure reducing valve which communicates the lower container with the atmosphere. The pressure reducing valve is opened for approximately 60 seconds for a soak- like processing when the temperature of the water reaches approximately 100 degrees C. Al- ternately, a pressure reducing valve is kept opened from the time when the temperature of the lower container reaches approximately 105 degrees C. to the time when the ingredients extra- cting operation is completed.

Jacques J Barriac assigned to Owens-Illinois Closure lnc

A molded plastic closure for a beverage con- tainer, the closure having a shell with a top panel and a depending skirt, the shell being molded in one piece from a hard thermoplastic material. The closure is provided with an annular flange which extends from the underside of the top panel and which forms an annular space with the inside of the skirt. A liner is formed in situ within the closure by compression molding from a com- pression moldable soft, rubbery thermoplastic material, the underside of the top panel and the inside of the annular flange serving as molding surfaces. The annular flange is supported against lateral loads by a series of ribs which extend bet- ween the annular flange and the depending skirt. The liner is interlocked with the annular flange by interengaging ribs and recesses. Both a top seal only closure for non-pressurized beverages and a top and side seal closure for pressurized beverages are disclosed.
