Granted: 2001-04-17
Abstract: A method is disclosed for producing infusion coffee filter packs in which a first strip of filter paper is placed adjacent to a mold having a cylindrical mold pocket, and the strip of filter paper is caused, either mechanically or by a vacuum, to conform to the cylindrical mold packet. The conforming step causes the surface area of the first strip of filter paper to stretch and increase by at least three percent relative to its area prior to the conforming step. A measure quantity of ground coffee is then deposited into the mold packet over the filter paper conformed thereto. A second strip of filter paper is placed over the first strip of filter paper and the ground coffee in the mold packet. The first and second strips of filter paper are then sealed together around the coffee filled mold pocket, as by a heat sealing press pressing and sealing the strips together. The filter paper is then trimmed as by die cutting to product a half inch wide flange area extending around the mold pocket. The presence of the one half inch flange in combination with the increased surface area caused by stretching results in a brewed coffee having an increase in soluble solids extraction and a decrease in the standard deviation of soluble solids extraction.

Title: Oil separator for refrigeration systems
Inventor: CAREY MICHAEL D
IPC: B04C5/28
Filed: 1990-10-02
Granted: 1994-11-15
Abstract: An oil separator for an air-cooled refrigeration system employing a screw compressor includes a U-shaped housing the bottom of which defines an oil sump and the upstanding leg portions of which are connected by flow splitting apparatus. The flow splitting apparatus divides and tangentially delivers portions of a mixture of compressed refrigerant gas received from the compressor, and in which oil is entrained, into the upper region of each leg portion.  The tangential delivery of the mixture into the leg portions and the centrifugal force created thereby causes the entrained oil to be separated from the gas at two distinct locations in the separator.  The separated oil drains along the inner walls of the leg portions of the separator to a common sump while the compressed refrigerant gas from which the oil has been separated exits each of the leg portions through open-ended conduits which extend into the leg portions.

Title: Automatic storage and retrieval apparatus
Inventor: STERNAD WILLIAM ARTHUR
IPC: E04H6/12
Filed: 1991-05-23
Granted: 2002-01-22
Abstract: Storage and retrieval apparatus and method using pallets for storing vehicles and other loads. A number of storage levels aligned vertically are reached by a pair of lifts in shafts which bracket the levels. A transfer mechanism can push a pallet and automobile from either lift onto any level. Each level is always filled with pallets and sized to exactly hold an integral number of pallets.      When a pallet is pushed into a level from one lift the intermediate pallets are pushed laterally to the opposite lift, resulting in the farthest pallet being ejected onto the opposite lift located at the same level. Separate loading stations are provided on ground level for each lift.      An automobile can be driven on or off a pallet or a load placed on or off a pallet at the loading station. A loading station mechanism can move a pallet with a load to be stored from the loading station onto a lift. The lift transfer mechanism can transfer a pallet with a load being retrieved from the lift onto the loading station mechanism adjacent the lift, and the loading station mechanism can move the pallet from there to the loading station. A computer having input apparatus, input sensors, output apparatus and displays, utilizes a program to control and optimize the operation. Input identifiers for each automobile, or other load, and pallet are entered into the computer upon storage to permit ready retrieval.
