Title: Neck engaging support for medical device
Inventor: ROSS JUDY L
IPC: A45F3/00
Filed: 1989-12-28
Abstract: A neck engaging support for a medical device or appliance that engages and is thus supported from the neck of a medical practitioner. More specifically, the present invention is a rod-like support device having a downwardly opening, generally U-shaped hook member dimensioned to fit around the neck of a user with the open area positioned in front of the chest region with one leg of the U-shaped member having a smaller hook for engagement with an IV bag in order to support the IV bag in elevated position without using the hands such as is frequently necessary during emergency situations when a patient is being conveyed on a stretcher from the site of the emergency to an ambulance, hospital or the like. The support of this invention enables the user of the device to actually carry one end of the stretcher while at the same time supporting an IV bag in an elevated position.      The rod-like support is constructed of thermoplastic material which can be obtained in straight condition and heated to a temperature that enables it to be deformed to fit individual users with the thermoplastic rod then becoming set in the desired shape when the rod cools thereby enabling the device to be custom fitted to individual users although they can be constructed of standard sizes since the plastic rod will have some degree of flexibility to enable it to be quickly and easily positioned around the neck of the user.

Title: Grit tolerating seal for a pump valve
Inventor: JOHNSON JERRY E
IPC: F04B53/10
Filed: 1990-03-08
Abstract: A valve element for a fluid pump comprises a rigid body and a flexible ring-shaped seal mounted on the body. The body includes an annular groove around its outer periphery in which the seal is mounted. An outer surface of the groove forms a first contact surface which engages a second contact surface defined by an inner circumference of the seal. Those contact surfaces form an angle of from So to loo with the longitudinal axis of the valve element to resist the creation of a gap between those surfaces. The seal includes a longitudinally projecting annular finger which is hooked into a correspondingly shaped channel of the recess to secure the seal to the body. The contact surface of the seal is configured to reduce the compression imposed on the front end of the seal so as to render that front end relatively flexible and able to effectively absorb forces applied thereagainst by grit disposed in fluid being pumped.
Patent CA-2016660-A1 (CA)
Inventor: PAJTAS SCOTT R
IPC: B60C7/10
Filed: 1990-05-14
Abstract: A side web non-pneumatic tire ("SWNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary honeycomb structure bounded by integrally molded outer and inner cylindrical coaxial and coextensive members ("hoops"), and, a single side web member. The outer hoop is supported and cushioned by the honeycomb which comprises a plurality of circumferentially spaced apart, angularly oppositely directed planar rib members (ribs) bounded by the side web on one side only. The side web, preferably on the outboard edge of the hoops, connects the hoops near their outboard edges. The opposite side surfaces of the side web lie at an angle  theta  in the range from 0 DEG  to 30 DEG  on either side of vertical to the rotational axis of the SWNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the outboard edges of all the ribs lie upon the inboard face of the web. The ribs on each side are angled at opposite angles in the range from 15 DEG  to 75 DEG  to radial planes which intersect them at their radially inner ends. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the SWNPT provide a load-supporting structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the SWNPT are derived from the honeycomb structure of an elastomer which provides the SWNPT with "ride" and "handling" comparable to those of a conventional pneumatic tire. The outer hoop has a vulcanized rubber tread secured to the hoop's outer surface to withstand travel over a road surface. The unribbed face of the single side web may be faced with an elastomeric sidewall to resemble the sidewall of a conventional pneumatic tire.
