A calf garment assembly having, a calf garment having an internal chamber and being substantially airtight and being in fluid communication with a pressurized air source, and a heating element working in conjunction with the calf garment to provide heated DVT therapy.

Heated compression therapy system and method

A method of forming toner particles having surface particles attached thereto includes the steps of aggregating a material of at least one binder material and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles. Toner particles prepared by such method include a core comprised of at least one binder and at least one colorant, and surface particles at an external surface of the toner particles, wherein at least about 50% of the surface particles are substantially completely covered by a portion of binder and a majority of the surface particles protrude from the toner particle surface a distance of at least 50% of the average particle size of the surface particles.

Surface particle attachment process, and particles made therefrom

A toner composition includes a binder, a colorant, and surface-treated sol-gel metal oxide particles surface-treated with a treatment agent.

Toner compositions with surface additives

A toner composition includes toner particles formed of a resin and a colorant; and one or more external additives, at least one of the external additives including polymeric particles, applied to a surface of the toner particles. The polymeric particles include a polymer selected from polymethylmethacrylate, modified polymethylmethacrylate, halogenated polymethylmethacrylates, and mixtures thereof.

Polymeric particles as external toner additives

A new snowmobile jack that does not require the hands or fingers of the user to be anywhere near the jack when raising and lowering the snowmobile. The jack comprises a T-bar that moves telescopically vertically to support a rear handle/tow bar on a snowmobile. A mechanical linkage operated by a first foot pedal raises and lowers the T-bar. A second mechanical device on the jack includes a positive latch operated by a second foot pedal. The latch positively prevents the first foot pedal and linkage from lowering the T-bar. Both foot pedals must be simultaneously depressed to release the latch and allow the T-bar to descend. The simultaneous action with two feet makes very unlikely any inadvertent lowering of the jack and obviates the need for the user to reach down to the jack with the hands.

Toner compositions and processes thereof

A color electrophotographic printing machine in which latent images having a resolution of at least 1.44 million pixels per square inch are recorded on a photoconductive member. Different color toner powder images are developed in superimposed registration with one another to form a composite multicolor image. The composite multicolor image is transferred from the photoconductive member to a receiving member. Toner particles which have a selected pigmentation and small volume average diameters are used to minimize curl of the receiving member.

A dry toner is added to a liquid carrier to replenish a liquid developer in an electrostatographic printing machine.

Method of replenishing a liquid developer

A process for avoiding, or minimizing toner contamination of electrodes in a scavengeless electrophotographic imaging apparatus which comprises adding to the donor roll present in said apparatus a toner comprised of resin, pigment, charge additive, and a metal oxide, or a mixture of metal oxides.

Toner process with metal oxides

An electrophotographic process for enabling substantially tamperproof images, including the generation of a latent image; developing the image with a toner composition comprised of resin particles, magnetite particles, and a colored organic soluble dye, a colored organic insoluble dye, or the salts thereof; and an optional additive component comprised of an aliphatic hydrocarbon or a polymeric alcohol of the formula

Magnetic image character recognition processes

Disclosed is a process for forming two-color images which comprises charging an imaging member, creating on the member a latent image comprising areas of high, medium, and low potential, developing the low areas of potential with a developer comprising a specific colored toner and a specific carrier as described herein, subsequently developing the high areas of potential with a developer comprising a specific black toner and a specific carrier as described herein, transferring the developed two-color image to a substrate, and permanently affixing the image to the substrate.

Process for forming two-color images

A process for the preparation of stable developer compositions, which comprises treating coated carrier particles with metal salts, or metal salts of fatty acids, and thereafter admixing these particles with a colored toner composition containing metal salts or metal salts of fatty acids, and comprised of resin particles and colored pigment particles, and wherein the salts are present in an amount of from about 0.01 to about 1 percent by weight.

Stable color developer compositions and process for the preparation

A negatively charged developer composition comprised of a toner composition with an average particle diameter of from about 4 to about 9 microns containing a mixture of styrene butadiene copolymers, and styrene methacrylate copolymers; pigment particles selected from the group consisting of cyan, magenta, yellow, red, blue, green, brown, and mixtures thereof; first external additive particles of colloidal silica; second external additive particles of fatty acid metal salts; and carrier particles comprised of a ferrite core with a polymeric coating thereover, which coating has dispersed therein conductive particles.

Negatively charged colored toner compositions

Disclosed is a process for affecting a reduction in fusing energy and permitting minimal image de-enhancement which comprises (1) providing a toner composition with toner resin particles, and pigment particles; (2) affecting spheroidization of the aforementioned toner composition; (3) incorporating the spheroidized toner composition into a xerographic imaging apparatus with a flash fusing device incorporated therein; (4) generating an electrostatic latent image in the imaging apparatus; (5) developing the image formed with the spherical toner composition; (6) transferring the image to a supporting substrate; and (7) permanently affixing the image thereto with energy emitted from a flash fusing device.
