Abstract: This invention provides an apparatus for covering the lens tip of a tonometer. The protective lens cover of the subject invention comprises a unitarily molded structure having an open end and an opposing closed end. The protective lens cover slidably receives onto the lens tip of a tonometer therein providing a temporary sterile environment to contact the eyeball of a patient.

Abstract: A manually operated dispensing pump is provided for delivering a precise quantity of ophthalmic solution to the surface of the eye in a desired spray pattern with an impact pressure on the eye that is comfortably tolerable by an individual. The dispensing pump basically comprises a push button actuator having a nozzle member disposed therein, a cap member for receiving the push button actuator and having a control ring for selectively limiting the downward travel of the actuator, and a pump chamber engaged in the cap member and in communication with the push-button actuator for pressurizing a metered quantity of ophthalmic solution.

Abstract: This invention involves a multilayer low friction ambulatory pad for treating or preventing bedsores and pressure sores, and for managing fluids discharged from a person's body. The pad may have the form of a diaper with panels fittable to a person's body. The pad has a first slippery nonporous layer on which is a moisture absorbent second layer. A slippery, thin, porous third layer is on the second layer. The three layers are peripherally bonded to form a nonpenable seam which permits unbonded areas of the layers to slide slightly with respect to each other. The third layer may be sprayed with a filmy, dry, slippery fourth layer. A fifth layer of lubricating material which may be a microencapsulated lubricant or a free lubricant is applied to the third and fourth layers to form a very slippery top surface. The fourth and fifth layers do not clog the pores of the third layer to pass air and fluids to the absorbent second layer. In other pads, the absorbent layer is omitted.

Abstract: Thermal spray apparatus for providing a stream of molten fluent material for coating a substrate, including a heat source including a flame for producing a stream of heated gas heated to sufficiently high temperature to melt the material; material advancing means for advancing a stream of heat fusible fluent material into the stream of heated gas to melt the material and produce the stream of molten fluent material; and a flame barrier intermediate the flame and the stream of molten fluent material for preventing reaction between the flame and the material, the flame barrier permits passage therethrough of the stream of heated gas.

Abstract: A bed pad structure is provided for the prevention of bed sores or pressure ulcers. The bed pad includes a pouch portion having an upper layer formed from a porous low friction material and a lower layer formed from a flexible impervious sheet material. The pouch portion is further constructed to enable easy insertion and removal of a lubricated insert in between the upper and lower layers. Lubrication from the insert can flow through the porous upper layer. The low friction characteristics of the upper layer plus the presence of the lubricant adjacent the patient substantially prevents friction and related wear which are contributing factors to the occurrence of bed sores.

Abstract: A plasma spray gun having an arc space within the gun housing for heating and ionizing an inert gas propelled therethrough includes an external, adjustable powder feed conduit so that the powder may be applied to the flame of the gun after it has left the gun nozzle. The plasma gun also utilizes a concave reflector attached to the gun to reflect the infrared radiation and direct it to a limited area on the substrate where most of radiant heat is absorbed.
