7168942 Method and apparatus for mold temperature control using air January 30, 2007
A method and apparatus for controlling the temperature of an injection mold passes pressurized air contained in an air supply tube through an orifice into an exhaust channel, wherein the pressure of the air in the exhaust channel is lower than the pressure of the air in the air supply
7097353 Method and device for indicating temperature August 29, 2006
Disclosed is a temperature indicating method and device. The device embodies a sealed tube containing a liquid and a float. The tube has markings on the exterior indicating temperature zones or, in the alternative, temperature gradients. The method disclosed includes inverting the tu
6895986 Flow control valve that may be used for mold temperature control systems May 24, 2005
A valve is formed to resist snap-action closure forces and provides a smooth closing action to minimize or eliminate water hammer. The valve is opened and closed by modulating the relative air pressures above and below a piston in the valve. Because the air pressures above and below the

A valve is formed to resist snap-action closure forces and provides a smooth closing action to minimize or eliminate water hammer. The valve is opened and closed by modulating the relative air pressures above and below a piston in the valve. Because the air pressures above and below the
6312628 Mold temperature control November 6, 2001
A method and system for controlling the temperature of a fluid cooled high temperature injection mold having fluid channels formed therein. A high temperature injection mold has an operating temperature above the boiling point of water. A flow of either elevated pressure or low pressure
6019003 Flow sensor turbine assembly with sapphire bearing and metallic insert February 1, 2000
The present invention provides an improved flow sensor turbine assembly for fluid flow measurement. The flow sensor turbine is connected in fluid communication with a conduit through which a fluid whose flow rate is to be measured flows. The flow sensor turbine assembly includes a turbin
4915214 Holder for numismatic items April 10, 1990
A holder (10) has a top housing (12) and a bottom housing (14) which encloses a numismatic item (24) for protection and display. The top housing (12) has an interior surface (28), an exterior surface (30), and edges (32, 34, 36, 38). The bottom housing (14) has an interior surface (4
4420446 Method for mold temperature control December 13, 1983
A method and apparatus (10) is disclosed which provides automatic control of the temperature of a fluid cooled plastic mold (12) during successive injections of liquid plastic into the mold. The temperature of the mold (12) is sensed by a probe (18) which provides a signal indicative of
4354812 Method and apparatus for mold temperature control October 19, 1982
A method and apparatus (10) is disclosed which provides automatic control of the temperature of a fluid cooled plastic mold (12) during successive injections of liquid plastic into the mold. The temperature of the mold (12) is sensed by a probe (18) which provides a signal indicative of
4153840 Double chamber ionization smoke detector May 8, 1979
A combustion product detector comprises two ionization chambers with a radioactive source in each chamber. One chamber is vented to the ambient atmosphere and the other serves as a reference. A communicating passage is provided between the chambers. An adjustable target is provided in th
4081684 Combustion product detector March 28, 1978
A combustion product detector contains a single ionization chamber having a radioactive source therein. It is provided with means to test the function of the device. The means includes an electrically non-conductive member which may be introduced in the ionization chamber to simulate (in
4059265 Elastic pull-type exerciser November 22, 1977
Grip member for elastic cord used for exercising contains two parallel cylindrical bores with slightly greater diameter than the cable, to slidingly receive the cable and prevent sliding of the cable through the grip member and permit adjusting of the active length of the cable used in
4000561 Device for severing tubular members January 4, 1977
Hand operated device for transversely severing polymeric synthetic resinous tubular members comprises resilient plastic housing members which snap together and a finger operated sliding member which carries a portion of a razor blade mounted in a described manner.
