Patent CA-1319716-C (CA)
Title: Annular lip type sealing ring with pre-loaded lip portions
Inventor: FRUEDENTHAL MERTON L
IPC: F16J15/32
Filed: 1986-10-17
Granted: 1993-06-29
Abstract: ABSTRACT    An annular lip type sealing ring includes an annular body with a generally U-shaped cross-section having a curved heel or base portion in the preferred embodiment and two spaced apart lip portions that define a groove therebetween.          The groove terminates at a closed inner end portion near the heel or base and at its opposite end adjacent an open end portion.  At least one of the lip portions has respective inwardly and outwardly extending lateral projections.  The outwardly extending  lateral  projection  seals  against  for example a valve shaft, pump plunger or the like.  The lip portion has an outer free end with an outer arcuate curved surface.   The  inwardly  extending  laterally  projecting portion  includes  an  inner  curved  surface.   An  elastomer pre-loads  the  lips with a  load that biases the lips to spread apart.  The inwardly extending lateral projections conform to and confine the elastomer.  The elastomer includes an elastomeric annular ring having a generally round cross-section before  insertion  into  the groove and a diameter greater than the width of the groove so that the elastomeric ring assumes the generally oblong or obround shape of the groove during use and thus pre-loads the lips as it attempts to regain its original shape.

Abstract: INK COMPOSITION FOR INK-JET PRINTER            Abstract of the Disclosure:       An aqueous-based ink composition for use in ink-jet printers is disclosed.  The composition comprises (a) a vehicle of about 5 to 95% water and the balance at least one glycol ether, such as diethylene glycol; (b) a dye, such as Food Black 2, having at least one negative-ly charged functional group per molecule, present in an amount up to about 10% of the vehicle composition; and (c) a cationic compound selected from the group consist-ing of alkanol ammonium compounds and cationic amide compounds, present in an amount such that there is at least one molecule of cationic compound for at least one of the negatively charged functional groups on the dye, the pH of the ink composition being maintained in the acidic region below about 7.      The ink composition of the invention evidences minimal crusting and reduced evaporation loss of water. The solubility of anioic dyes is increased in the acidic medium over that otherwise obtainable, due to the pres-ence of the alkanol ammonium compound or amide.  The ink composition of the invention is suitably employed in any of the ink-jet printers commonly in use.

Abstract: WRIST STRAP CONSTRUCTION FOR A BASEBALL GLOVE            Abstract of the Disclosure An improved wrist strap construction for a base-ball glove, comprising a wrist strap extending transversely with respect to the glove on the back wall of the glove generally adjacent the bottom of the glove, and an elastic web securing the inner end of the wrist strap to the glove at one side of an extension of the hand opening at the bottom of the glove extending up toward the finger stalls of the glove.  The elastic web is stetchable to permit limited movement of the wrist strap generally transversely with respect to the back wall of the glove.  The outer free end of the wrist strap is adapted to be pulled against the resistance of the elastic web thereby to draw back wall portions of the glove on opposite sides of the extension of the hand opening toward one another to adjust the size of the opening to fit the hand.  The wrist strap is releasably fastenable in an adjusted position wherein the elastic web is adapted to maintain the wrist strap tensioned for pro-viding a snug fit of the glove on the hand and also to permit yielding of the wrist strap when the glove is flexed so as not to unduly restrain movement of the hand.  The elastic web is concealed from view when the wrist strap is fastened in its adjusted position.

Abstract: METHOD AND APPARATUS FOR DELIVERING              A PRESCRIPTIVE ELECTRICAL SIGNAL          Abstract of the Disclosure Apparatus and method of transcranial electrical nerve stimulation is disclosed including the generation of a reliable, reproducible, programmable, prescriptive waveform. The applied signal has a therapeutic effect which, depending on  the  prescription,  ameliorates  pain,  assists  in ameliorating stress or anxiety-related disorders, minimizes the withdrawal symptoms in drug detoxification and the like. The electrical signal is a continuous and interrupted complex of pulses and has a zero net cummulative charge. The preferred application of the prescribed signal is via selected contact points on the skin of the ear.  The contact points are chosen because of their known affinity for changing endogenous concentrations of neurotransmitters and neuromodulators  in the brain.   The parameters of the electrical prescription include current amplitude, pulse width, zero net charge delivered in any pulse, time between adjacent pulses, number of pulses in a packet, the time between adjacent packets in a pulse train and the number of pulse, trains in the prescription.  Monitoring of the acutal delivered signal to the patient is performed.  The monitored response is used to correct system output to insure adherence with the signal parameters that are prescribed to optimize accuracy of signal application and therapeutic results.
