...that in the early 1940s GE engineer James Wright was charged with a task of utmost importance to the war effort: develop a cheap substitute for rubber that could be used to produce tires, gas masks and a whole host of military gear. Wright tackled the task diligently -- and wound up inventing Silly Putty.

| Number | Title | Issue Date |
| 7329449 | Method and apparatus for reliable printing on linerless label stock A system comprising a linerless pressure sensitive label stock and a printer for printing on linerless pressure sensitive label stock exhibit reduced tendency for exposed adhesive to stick to printer components. The linerless pressure sensitive label stock has a plu... | 02/12/2008 |
| 6695495 | Constant density printer system An ink density closed loop control system for an ink ribbon of an impact printer having a reservoir roller formed of an ink absorbent material with at least one or more channels within the reservoir roller fluidly connected to a pump and ink supply. A tra... | 02/24/2004 |
| 5435656 | Back stop structure for matrix pin print head A matrix pin print head is set to a fixed distance (17) relative to a print counter support (2), where a recording substrate (3) rests on the print counter support (2). An ink ribbon (4) is guided in front of the print pins (5) between the matrix pin prin... | 07/25/1995 |
| 4915519 | Direct negative from resistive ribbon An improved apparatus and process are described in which a direct negative is formed using commercially available multi-stylus recording heads. A negative precursor comprised of a transparent support and an opaque thermoplastic ink layer carried thereon, ... | 04/10/1990 |
| 4806031 | Uniform print density and registration in an impact printer Commencing with the first print hammer(s) "out", or actuated, on each print line the hammer drive current is boosted 10% for a period, ranging from 25%=650 microseconds for single part forms to 50% for multi-part forms, of the total print hammer flight ti... | 02/21/1989 |
| 4558963 | Feed rates and two-mode embodiments for thermal transfer medium conservation Conservation of ribbon 40 is achieved by underfeeding ribbon 40 relative to movement of thermal printhead 16. Pressure of printhead 16 may be low enough that smearing from a typical ribbon 40 does not occur. Gears 208, 210, 212, 214 and 216 may be positio... | 12/17/1985 |
| 4477198 | Modified resistive layer in thermal transfer medium having lubricating contact graphite coating A thermal ribbon having a minute coating of graphite powder on the outer side of the resistive layer. The improved electrical interface with print electrodes reduces ribbon and printhead damage. The graphite also reduces friction and loosens material whic... | 10/16/1984 |
| 4461586 | Ink ribbon for use in electrothermic non-impact recording An ink ribbon for use in electrothermic non-impact recording comprising an electroconductive base layer and an electroconductive thermal-transferable ink layer which are layered. The base layer comprises a binder resin and an electroconductive material di... | 07/24/1984 |
| 4421429 | Resistive substrate for thermal printing ribbons comprising a mixture of thermosetting polyimide, thermoplastic polyimide, and conductive particulate material Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimide, and graphite. It has a steel support layer and an intermediate layer of silicon dioxide. An outer layer on the steel is the thermal i... | 12/20/1983 |
| 4419024 | Silicon dioxide intermediate layer in thermal transfer medium Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimide, and graphite. It has a steel support layer and an intermediate layer of silicon dioxide. An outer layer on the steel is the thermal i... | 12/06/1983 |
| 4400100 | Four layered ribbon for electrothermal printing Four layer resistive ribbon transfer tapes for use in electrothermic printing devices are fabricated. The tapes are comprised of a substrate having a heat transferable ink on one of its surfaces, and on its opposing surface there is disposed a metal layer... | 08/23/1983 |
