In said seat (25) there is housed a centering member (40) of the capsules (C), elastically movable in an axial direction and provided with a guide and centering surface (40A) of the capsules, facing towards the second of said portions of the infusion chamber.

Footwear with a sole formed from an elastomeric material whose grip is improved on ground where the interface may include an intermediate foreign substance, this sole comprising lugs (31) separated from each other by grooves (35). The walls of the grooves (35) are cut into the thickness of the elastomeric material and delimit patterns with sharp angles in the profile of said lugs (31) which can pierce said foreign substance to establish direct dry contact between the two surfaces. Each lug (31) forms a star-shaped pattern having at least five arms in the form of stems (32) distributed over its, profile and each stem (32) is orientated radially towards the outside of the pattern and terminates in an end. Each stem (32) is separated from its neighbor by a recess (38) in the profile of the lug. Finally, each lug (31) has a stem (32) engaged in a space of the adjacent groove (35) which is delimited by a recess (38) between two neighboring stems in the profile of a second lug neighboring the first lug.

A single-use capsule for preparing a food liquid from a food substance contained in the capsule by introducing water in the capsule and passing water through the substance using centrifugal forces for producing the food liquid which is centrifuged peripherally in the capsule relatively to a central axis (A) of the capsule. The capsule includes an enclosure containing a predetermined amount of food substance, and a plurality of outlet openings for enabling the food liquid to leave the enclosure under the centrifugal forces exerted in the capsule, with the outlet openings being arranged at a substantially peripheral portion of wall of the capsule.

A device used to treat heart disease by decreasing the size of a diseased heart, or to prevent further enlargement of a diseased heart. The device works by limiting the volume of blood entering the heart during each cardiac cycle. The device partitions blood within the heart, and protects the heart from excessive volume and pressure of blood. The device is placed within the interior of the heart, particularly within a ventricular cavity. The device is a hollow sac, with two openings, which simulates the shape and size of the interior lining of a ventricle of a normal heart. It allows the ventricle to fill through one opening juxtaposed to the annulus of the inflow valve to a predetermined, normal volume, and limits filling of the heart beyond that volume. It then allows blood to be easily ejected through the second opening through the outflow valve. By limiting the amount of blood entering the ventricle, the ventricle is not subjected to the harmful effect of excessive volume and pressure of blood during diastole, the period of the cardiac cycle when the heart is at rest. This allows the heart to decrease in size, or to reverse remodel, and to recover lost function. In some applications, a second device may be simultaneously placed inside the heart to take up excessive space between the heart and the primary device.

An end mill is provided that includes a shank section and a fluted section. One or more helical teeth are disposed along an outer surface of the fluted section. Each helical tooth has a cutting surface and a relief wall that intersect to form an angle defining a helical cutting edge. The cutting surface of each helical tooth includes a first section, a second section, and a take-off peak disposed between the first section and second section. The cutting edge of each helical tooth includes a first portion having a first constant angle, and a second portion having a second constant angle unequal to the first constant angle, and an arcuate transition section connecting the first portion and second portion. Some embodiments of the present invention include more portions than the aforesaid first and second portions.

The present invention provides an apparatus and method for producing substantially clear ice in a variety of desired shapes. An insulated ice mold form containing one or more mold cells is suspended over a liquid water reservoir contained in an insulated container. Each ice mold cell is exposed to freezing air resulting in the formation of ice in each mold cell with ice formation progressing from the top to the bottom of each ice mold cell. A liquid water reservoir below each ice mold cell serves as an impurity sink into which impurities and gases are driven as ice crystals form in each ice mold cell and as a heat sink to substantially arrest ice shape growth beyond the bottom of each ice mold cell at or near the ice-reservoir water interface.
