Title: Method and apparatus for feeding and opening a beverage carrier
Inventor: OLSEN PETER CHRISTAIN JR
IPC: B65B43/26
Filed: 1987-04-30
Granted: 1990-05-22
Abstract: Abstract of the Invention A machine for feeding a collapsed beverage can carrier sleeve to a flight bar conveyor and introducing the sleeve in fully open condition to the pocket of the conveyor. After leaving the feed rolls the collapsed carrier sleeve is moved through a fixed guide by lugs on a movable chair. The end flaps on the upwardly facing side panel are held in place on the guide while the end flaps on the downwardly facing side panel are moved downwardly by a fixed cam surface. The substantially opened sleeve is then either given a final kick by rotating arms or is propelled by the feed lugs to accelerate it into the pocket while at the same time fully straightening and opening the sleeve. The carton dimension corresponding to the length of the pocket is the same as the length of the pocket, resulting in more pockets per conveyor length and permitting operation at slower conveyor speeds.

Granted: 1992-06-23
Abstract: METHODS FOR TREATMENT OF SUNDAMAGED HUMAN SKIN WITH RETINOIDS            Abstract of the Disclosure Various effects of photoaging or sundamage of skin including impairment of differentiation of epidermal epithelial cells and loss of collagen fibers, abnormal changes in elastic fibers and deterioration of small blood vessels in the dermis of the skin are retarded by applying topically to the epidermis in a maintenance therapy program effective amounts of retinoids including retinoid derivatives and stereoisomers thereof such that epithelial growths are substantially reduced and prevented and the skin substantially regains and maintains its firmness, turgor and elasticity.  Moreover, with persistent treatment dermal blood cells and vessels increase and the epidermis and dermis thicken, resulting in improved ability of the skin to sense, resist and recover from irritation or injury. Further, hyperpigmentation, lines and wrinkles due to aging are reduced and prevented.  The treatment is particularly useful for human facial skin and preferably applied in amounts insufficient to cause excessive irritation.

Title: Pool-level sensing probe and automatic level control for twin-belt continuous metal casting machines
Inventor: KAISER TIMOTHY D
IPC: B22D11/16
Filed: 1987-09-11
Granted: 1992-10-20
Abstract: POOL-LEVEL SENSING AND AUTOMATIC LEVEL CONTROL FOR TWIN-BELT CONTINUOUS METAL CASTING MACHINES     Abstract of the Disclosure In continuous metal-casting machine utilizing one or more thin flexible belts as mold surfaces, a suitably placed thermal sensing probe which contacts the reverse side of a casting belt results in enhanced control of molten-metal pool levels, in contrast to the earlier systems where a series of separately monitored probes were disposed serially against the belt from upstream to downstream, each of which registered a separately monitored "yes" or "no" signal.   In accordance with the present invention, an intermediate temperature is selected as the control point, at one location in the mold.  If the pool of molten metal rises above the optimum level, the sensing probe will register a correspondingly increased temperature.  If the pool falls below optimum, the probe will register a cooler temperature.  The resulting electrical signals are processed by an electronic circuit.  The resultmay be displayed for manual control of metal feed or machine speed, or a resulting control signal may be employed to control automatically the flow of molten metal into the mold cavity or, alternatively, to control the speed of thecasting belts which convey metal through the casting machine.  Multiple sensing probes disposed serially along the direction of motion of the moving mold afford a greater physical length of effectiveness of pool-level control when they are wired in series or otherwise related so that their signals are summed up to result in only one combined single-channel signal to be monitored or to be used for automatic control.

Title: Elastomeric hinge spring
Inventor: DEL SANDERS MYRON
IPC: E05D11/10
Filed: 1987-12-01
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE           An elastomeric hinge spring intended primarily for the doors of vehicles, has an outwardly projecting detent formed on a first bracket mounted on the vehicle frame and a roller formed of a compressible elastomeric material mounted on a second bracket attached to the vehicle door.   The detent is in the path of movement followed by the roller upon movement of the second bracket and door toward the closed position.   The roller retains the door in the open position requiring temporary compression of the roller to move of the door toward the closed position.  The detent may have two projections which provide an intermediate door position or have an elongated ramp configuration to achieve other door opening and closing characteristics.   Another detent may be formed on the first bracket to partially compress the roller when the door is in the closed position to bias the door toward the open position.    The elastomeric roller completely eliminates metal spring components heretofore used in prior hinge spring devices.

Title: Process for fabricating parts from particulate material
Inventor: JOHNSON KENNETH P
IPC: B22F1/00
Filed: 1988-10-06
Granted: 1995-04-04
Abstract: Provided is a method of manufacturing sintered parts from particulate material, e.g., metal or ceramic parts.  The method comprises mixing together predetermined amounts of powdered particulate material and a binder, which mixture is then molded under heat and pressure.  The binder comprises at least a lower melting point component and a higher melting point component, with the lower melting point component remaining in a liquid state, becoming semi-solid or relatively soft upon cooling to ambient temperatures. Prior to sintering, the lower melting point component of the binder is selectively dissolved in a liquid solvent, and the higher melting point component is removed upon heating at temperatures below the sintering temperature.  The result is a process which eliminates or prevents the formation of oxides, substantially reduces the time required for debinding and sintering, and essentially eliminates cracking in the finished part.

Title: Supply of controlled medium-pressure co -gas in simple convenient disposable packaging
Inventor: PLESTER GEORGE
IPC: B67D1/04
Filed: 1988-10-14
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE        A gas generator chemically generates a gas from a chemical reaction between two reagents contained within a common container.   The reagents are normally separated by a gas generation chamber into different regions of the container in the absence of gas generation therein.   A reference pressure source of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the gas generation chamber is less than the predetermined pressure.  A valve in fluid communication with the gas generation chamber is provided to withdraw the generated gas from the chamber when OPEN.  As the gas flows through the valve from the chamber the gas pressure in the chamber drops permitting more mixing of the reagents.  When the chamber pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source,  the reagents become separated again and gas generation ceases.
