Title: Adaptive print hammer timing system
Inventor: MCCRIMMON KENNETH A JR
IPC: B41J19/18
Filed: 1988-08-02
Granted: 1992-11-17
Abstract: Abstract of the Disclosure In a printer in which an elongated shuttle is driven in reciprocating fashion across a print paper with hammers mounted along the length of the shuttle being selectively fired to print dots on -the paper, a timing system provides hammer fire pulses denoting the positions of the shuttle at which hammer firing should be initiated to print in the proper dot positions.  Proper timing is maintained so as to allow for printing during acceleration and deceleration as well as during constant velocity movement of the shuttle by determining the average shuttle velocity between each successive pair of fence post pulses generated by a shuttle-coupled encoder. The average velocities are represented by the time lapses between occurrence of the pairs of fence post pulses which are measured and stored during each startup of the printer as well as each time the nominal operating shuttle velocity is changed as part of a change in printer operation.   Dot positions are represented by a percentage of the distance between a pair of fence post pulses, such that the time of occurrence of each dot position following the immediately prior fence post pulse can be determined by applying the percentage to the stored time lapse between the pair of pulses. The time position of each dot position as so determined is stepped back by the fixed hammer flight time to arrive at the hammer fire pulse times which are referenced to the immediately prior fence post pulse and which are used during each stroke of the shuttle.

Abstract: ABSTRACT OF THE DISCLOSURE         A game utilizing a deck of playing cards.  The playing cards each have letter designations in the upper left hand corner in each of two different invertible positions of the card with the letter designation differing from each other.  In the lower right hand corner of each of the two invertible positions of the card, there is provided an "information center" giving the letter designation of the card should the card be inverted.  Thus, as the cards are held in a hand, one adjacent to the other, both the letter designating the card in its upright position as well as the letter available to the card, should the card be inverted, are both visible to the player.  Cards are selected and a word must be formed with the cards being able to be positioned in either of their two inverted positions.  After the word is formed, the word is then used as an acronym in the formation of a sentence, with the sentence preferably being associated with the word itself.

Abstract: ABSTRACT OF THE DISCLOSURE            A defoaming device for separating foam and bubbles from a liquid, such as blood, is disclosed.  The device can be used  in conjunction with a medical device, such as a membrane oxygenator, for separating air from blood while minimizing blood contact with the antifoam agent used in the device.  The device includes a reservoir and a filtering material that does not contain any antifoaming agent.   This filtering  material   is positioned in a lower portion of the reservoir to separate foam and bubbles from the liquid.  An element containing an antifoaming agent is positioned in the reservoir above the maximum surface fluid level therein and receives the foam and bubbles that rise from the filtering  material.  Contact of the liquid with the antifoaming agent is substantially avoided.

Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a gas-permeable, conformable material (20) to a shape-defining surface of a shaped parent metal (10). The gas-permeable material (20), when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the parent metal (10) melts and flows from the mold into a receptacle without disturbing the mold. Oxidation reaction product is then grown by oxidation of the molten parent metal with a vapor-phase oxidant to form an oxidation reaction product which grows into the mold cavity and is shaped by it. A ceramic body is recovered from the mold and has substantially the same shape as the pattern section (12,14,18) of the original shaped parent metal (10).
