Abstract: A device for storing oil or another vaporizable substance can include a porous body adapted to absorb a volume of liquid and to retain the volume of liquid for vaporization. A porous body can include a matrix of pores adapted to take up and retain oil by capillary action. A method of vaporizing oil can include storing the oil in a porous body and heating the body.

Abstract: A vaporizer can include a reservoir for holding oil, a chamber for holding vapor, a feeder for feeding oil from the reservoir to the chamber, and a heater for heating oil. A feeder can be configured to feed oil from the reservoir to the chamber by capillary action. A vaporizer can include a plug sealingly coupled to the reservoir and configured to slide relative to at least a portion of the reservoir. A heater can include at least one of a laser, a resistance heater, a wire, a coil, a wire at least partially disposed in a housing, and a combination thereof. A vaporizer can include a controller and can be configured to heat a to heater to a first temperature for a first time period, reduce the temperature of the heater, and maintain the heater at a second temperature for a second time period.

Abstract: A vaporizer can include a body, an air inlet for airflow into the body, an air outlet for airflow out of the body and a chamber disposed fluidically between the inlet and the outlet. The chamber can be configured to hold a porous body having fluid disposed therein. The porous body can be removable. A vaporizer can include a heater disposed in the chamber for heating and removably holding the porous body. The heater can be fluidically insulated and can be structurally supported by one or more electrical conductors.

Abstract: An adjustable vascular compression device assists in achieving partial or full occlusion of a blood vessel when applied to a patient's limb, for example, during or following a medical procedure. Pads on the device apply preferential compression to portions of the circumference of the limb so as to enable blood flow through adjacent blood vessels during the compression period. Further, rapid fastening, tightening, loosening and release is enabled by a single mechanism, and gradual adjustments to the tightness may be made without releasing said mechanism.

Abstract: A mechanical pencil for automatic drawing machines is disclosed which feeds lead segments to the writing surface as the pencil is alternately pressed against and lifted from the writing surface. The pencil includes a housing having a reserve lead containment chamber and a main internal cavity. A collet split into two portions is mounted within the internal cavity beneath an opening between the main cavity and the containment chamber and has outer cone-shaped camming surfaces and first and second axially spaced, cylindrical inner clamping surfaces. A friction tube with an inner bore adapted to frictionally engage a lead segment is mounted beneath the collet and holds a lead segment to support it against the writing surface.
