Title: Molten thermoplastic material supply system with distribution manifold having reverse flush filter and automatic drain
Inventor: SIDDIQUI SHAHID A
IPC: B05C11/10
Filed: 1996-10-04
Abstract: A system for supplying molten thermoplastic material to a dispenser through a supply hose comprises a hopper for storing the thermoplastic material.A heating grid associated with the hopper heats and melts the thermoplastic material. A reservoir block receives the melted material from the grid. The reservoir block includes a reservoir into which the melted material flows from the grid. A manifold assembly is supported below the reservoir block for receiving material from the reservoir. The manifold assembly includes a fitting for connection to the supply hose, a pump for pumping the material through the supply hose to the dispenser, a passageway system connecting the pump to the fitting for supplying a flow of material from the pump to the fitting, a filter connected to the passageway system for filtering impurities in the material after the material has been pumped, and a valving arrangement connected to the passageway system and separate from the filter which selectively directs a flow of the material in the passageway system through the filter to backflush the filter. The filter and the valving arrangement permit the filter to be backflushed without dislodging the contaminants in the filter. The backflushing capability allows the filter to be cleaned periodically without removal of the filter and without changing the position of the filter. When the filter is backflushed, the material flows through a drain valve assembly which opens automatically in response to pressureof the material from the pump.

Title: Lottery ticket templates for combinations
Inventor: LORD MICHAEL ANTHONY
IPC: A63F3/06
Filed: 1996-11-19
Abstract: The three templates are intended for use with lottery tickets. Each templates creates a partial series of combinations from a predetermined number of choices. From a predetermined field of numbers. What is unique is that each template which has its own series of combinations guarantees that the predetermined number of choices are boxed three ways with the least amount of combinations. In use each template is rectangular in shape and the same size as each other, which are rectangular in shape. The templates are transparent plastic with a silkscreen print. The chosen numbers from a predetermined number of choices are to be marked with a washable marker in the pick boxes at the top of each template which are arranged horizontally, at the top of each template. The chosen numbers are then matched to the series of combinations created for each template, using corresponding alphabetical letters. Beside each series of combinations being the alphabetical letter is a marking hole. Unlike known prior art devices these templates fit directly on top of the lottery ticket, each template combination is allotted a number that must match the number allotted to each individual lottery ticket combination; thus not being able to double enter numbers or mix-up combinations. These templates enable the player to mark his/her lottery ticket directly and rapidly without marking any other embodiment.

Title: Apparatus and method of delivery of gas-supersaturated liquids
Inventor: SPEARS JAMES RICHARD
IPC: C01B13/02
Filed: 1995-12-06
Abstract: This invention is an apparatus (10) for delivery of a gas, such as oxygen, solution into an environment (such as a coronary artery). The apparatus includes a high-pressure tubular housing (12) defining a lumen (14) there within. A plurality of axially disposed concentric tubes (16) are supported within the lumen (14).

Title: Flow sensitive, acceleration sensitive shock absorber
Inventor: RICHARDSON DONALD G
IPC: F16F9/32
Filed: 1996-03-01
Abstract: An acceleration sensitive shock absorber has a tubular housing and a piston assembly in the housing (11) dividing the housing into an upper chamber (13) and a lower chamber (12). The piston is connected to the wheel of a vehicle and the housing is connected to the chassis of the vehicle. Fluid can pass between the upper and lower chamber to the upper chamber upon downward acceleration of the wheel. A movable inertia valve (46) in the piston assembly opens the first port when acceleration of the wheel of the vehicle is greater than a predetermined magnitude for increasing flow between the chambers. In addition, there is a first restricted flow path (48) downstream from the first port for creating hydraulic pressure which biases the inertia valve in an open position in response to fluid flow between the chambers. There is a second port (43) or passage for providing fluid flow from the upper chamber to the lower chamber. A second restricted flow path upstream from the second which provides hydraulic pressure to decrease the response time during compression.
