Title: Medical gas adapter with molded spring bias
Inventor: LACKLER PETER A
IPC: F16L37/14
Filed: 1989-09-18
Granted: 1993-03-09
Abstract: Abstract of the Disclosure A medical gas adapter useable for connecting a gas tubing or other end use device to a gas service outlet to supply the gas for its end use.  The adapter has a fixed adapter assembly including an elongated nose that fits within the gas service outlet to activate a valve for releasing gas to the adapter.          The fixed adapter assembly also includes a connector means at its other end for connection to the end use device.  A release knob is rotatably affixed to the fixed adapter assembly and can be rotated between a first position where a locking mechanism retains the adapter held within the service outlet and a second position where the adapter is released from the service outlet.          The release knob is spring biased to return to its first position in the preferred embodiment by a pair of molded leaf springs integrally molded with the release knob for inexpensive manufacture and assembly.  The leaf springs are distorted by a pair of disc studs that are fixed to the fixed adapter assembly but cause the distortion in the leaf springs as the leaf springs are rotated about the disc studs.  As such, therefore, in its second position, the spring bias causes the release knob to snap back to its first position when released by the user.

Title: Electrostatic cleaning of electrodes in an electrographic printer
Inventor: RIZZA ROBERT S
IPC: G03G15/32
Filed: 1989-09-25
Granted: 1993-04-27
Abstract: ABSTRACT    The print head of an electorgraphic printer is cleaned electrostatically.  The printhead has a number of electrodes in an electrode array, which cooperate with a dielectric belt.  Periodically, printing with the printer is interrupted (e.g. after every 100 pages of printing, or about every minute), and then substantially all of the electrodes are energized at the same time for a time period sufficient to effect burning off of contaminants from the electrodes (e.g. about the time it takes to print four pages, or about 3 seconds).  A host computer controls the operation of the printer components.          The printer developer unit may be moved away from the dielectric belt prior to the energization of all of the electrodes to effect cleaning.

Abstract: The present invention concerns a circuit by the aid of which the power (Pin) emitted from the RF power sensor (SK) of a radio telephone is processed to become a detector voltage which is proportional to said power. The circuit comprises a transistor (Q2) acting as an active rectifier, which in the ascending part of the positive half cycle of the power (Pin) charges the capacitor (C3). In the descending part of the power the capacitor starts to discharge at a time constant which is remarkably greater than the cycle length of the power Pin). The transistor is biassed by means of a transistor (Q1) so that it is conductive even on the lowest power levels.
Patent NO-176362-C (NO)
Inventor: SODERLUND HANS ERIK
IPC: C12Q1/68
Filed: 1989-11-28
Abstract: The invention provides for detection of changes in a nucleotide sequence based on the determination of the nucleotide sequence over the region of interest. The first step of the process involves obtaining an amplified DNA sample in which at least one attachment moiety has been introduced into at least one strand of a target polynucleotide by a modified polymerase chain reaction. This can be accomplished by synthesizing DNA using the target nucleic acid polymer as a template and using at least one amplification primer, which includes an attachment moiety bonded to the oligonucleotide. The resulting amplification mixture is repeatedly cycled between a polymerization condition and a denaturation condition occurs for a number of cycles sufficient to produce copies of the target nucleic acid polymer in a quantity suitable for use in a DNA sequencing procedure to form an amplified sample comprising copies of the target nucleic acid sequence bonded to the attachment moiety. After amplification, the strands of target nucleic acid polymer carrying an attachment moiety are captured using a solid matrix coated with an attachment site to which the attachment moiety or a modification thereof can bind. In this way, the strands of target nucleic acid become bound to the solid matrix and can be readily separated with the solid matrix from unbound reactants for sequencing.

Granted: 1995-10-10
Abstract: An apparatus is provided for transferring articles from a pickup position to a pickoff position and thence to a dropoff position. The apparatus includes apair of pickup arms which are spaced apart to engage lugs oppositely extending from an article to be transferred. As the transfer arms are caused to be moved rotatably, the article is transferred to the pickoff position whereat the lugs are adjacent to stepped end portions of a pair of pickoff arms. Further movement of the transfer arms causes the article to engage surfaces of the stepped free ends of the pickoff arms and to be supported by engagement of the lugs with surfaces of the stepped end portions of the pickoff arms. Afterwards, the pickoff arms are turned to allow the article to descend until, at a predetermined position, the lugs of the article become engaged with a conveyor and become disengaged from the pickoff arms. Successive ones of the articles are supported by engagement of thelugs with the conveyor such that main body portions of the articles are submerged in a treating bath beneath the conveyor.

Title: Universal banner display apparatus
Inventor: BURKE EDWARD A
IPC: G09F17/00
Filed: 1991-07-22
Granted: 1997-04-29
Abstract: A kit for mounting a banner or flag on any pole.  The kit includes one or more horizontal arms (placed at the top, and optionally the bottom of the banner) to ensure that the banner is visible even in windless conditions. These arms are joined by a vertical strut.  L-brackets maintain the horizontal arms perpendicular to the vertical strut.  The banner may be fastened to the vertical strut by like means.  The L-brackets contain fixtures to fasten to grommets at the corners of the banner, to maintain the banner in a taut configuration, and further to fasten universally adaptable hoops, which hoops encircle the pole.  The banner frame is permitted to rotate about the vertical axis of the pole on the hoops.  A flexible rubberized shock cord is attached at its upper end to the pole by a band clamp or the like, and extends down to the upper L-bracket.  As the banner frame rotates, the shock cord is wound around the pole.  The length of the cord is selected so that 1.5 to 2 complete revolutions are possible.  When the wind dies, the elasticity of the shock cord returns the banner frame to the original position.          In the unlikely event that the wind "follows" the banner forcing it through the permitted 1.5 to 2 revolutions, the shock cord is designed to snap before dangerous wind loads are applied to the pole.
