Process for making an elastomeric glove
A nitrile-rubber medical exam glove composed of a glove body which is a flexible layer of nitrile-butadiene rubber. The glove body has a chlorinated first surface forming a donning side of the glove body and an un-chlorinated second surface forming a grip side of the glove body. The elastomeric glove also includes a substantially uniform distribution of a release agent distributed over the un-chlorinated second surface of the glove body. The elastomeric glove has: (a) an average thickness of between about 0.03 to 0.12 mm in a palm region of the glove body as measured in accordance with ASTM D3767, procedure A; (b) an un-chlorinated second surface of the glove body characterized by a Surface Root Mean Square Roughness of from about 3.00 m to about 6.55 m; and (c) a failure rate of less than about 1 percent when the elastomeric glove is subjected to pinhole leak testing generally in accordance with ASTM D5151-06.

Methods for three-dimensional model printing
A method of printing a three-dimensional object is provided. The method includes selectively dispensing, layer by layer, one or more materials to form the three-dimensional object; selectively dispensing, layer by layer, one or more materials to form a support construction for the three-dimensional object; selectively dispensing, layer by layer, one or more materials to form a rigid exterior construction around at least part of the support construction, the rigid exterior having substantially similar strength and elasticity to the three-dimensional object; and forming a release construction around the rigid exterior construction, the release construction being between the rigid exterior construction and the three-dimensional object.
SYSTEMS AND METHODS FOR MAKING AND USING A FITTED CAP FOR APPLYING A SHAPED SEALANT SHROUD TO A PORTION OF A FASTENER
A system (200) for making a fitted cap (300) comprises a fastener template (202), dimensionally identical to a portion (106) of a fastener (100) and extending from a support plate (210), and a first plurality of through-openings (212) penetrating the support plate (210) and arranged about the fastener template (202). The system (200) also comprises a precursor cap (320) that is geometrically complementary to the fastener template (202), first means (217) for heating a first polymer sheet (270), and second means (219) for applying suction to the first polymer sheet (270) through the first plurality of through-openings (212) to vacuum-form the first polymer sheet (270) over the precursor cap (320). After vacuum-forming the first polymer sheet (270) over the precursor cap (320), at least a portion of the first polymer sheet (270) forms the fitted cap (300). The fitted cap (300) is configured to apply a shaped sealant shroud (590) to the portion (106) of the fastener (100).
IMPRINT LITHOGRAPHY PROCESS AND METHODS ON CURVED SURFACES
Methods for creating a pattern on a curved surface and an optical structure (e.g., curved waveguide, a lens having an antireflective feature, an optical structure of a wearable head device) are disclosed. In some embodiments, the method comprises: depositing a patterning material on a curved surface; positioning a superstrate over the patterning material, the superstrate comprising a template for creating the pattern; applying, using the patterning material, a force between the curved surface and the superstrate; curing the patterning material, wherein the cured patterning material comprises the pattern; and removing the superstrate. In some embodiments, the method comprises forming the optical structure using the pattern.

System for applying a fluid to a surface
An application system for depositing a fluid product on a surface. The application system comprises a frame mounted on a locomotive system ensuring the displacement of the frame over the surface, a tank mounted on the frame and receiving the fluid product to be applied, and an application head fluidically connected with the tank via a supply nozzle. The application system comprises a guiding system which comprises detectors to detect the obstacles in the environment of the application system. Such an application system allows for an even application of the fluid product over the entire surface.

Method for producing a counter-form and method for manufacturing a part having a complex shape using such a counter-form
A method for producing a counter-form (20) for manufacturing a part having a complex shape (24) by pressure sintering densification. The counter-form (20) is formed from successive layers produced by numerically-controlled three-dimensional (3D) additive printing according to the following steps: numerically recording a three-dimensional negative of the part to be produced (24) in a control unit of a three-dimensional additive printing system in order to constitute the positive form of the counter-form to be produced; producing the counter-form (20) using a 3D additive printing technique. The part having a complex shape (24d) is then manufactured by pressure sintering, then separated from the counter-form which is also sintered (20).
