Expandable reamer

An expandable reamer includes, in one exemplary embodiment thereof, a cannulated shaft and a plurality of straight cutting blades having deformable points. The blades are hingably outwardly rotatable at the deformation points between a contracted position and an expanded position. In the contracted position, the blades are substantially parallel to the longitudinal axis of the cannulated shaft and, in the expanded position, the blades have at least a portion oriented radially outward from the longitudinal axis, thereby forming a larger diameter cutting surface in the expanded position and in the contracted position. The blades are formed from a portion of the cannulated shaft by, e.g. milling longitudinally extending slots through the wall of the cannulated shaft, the slots serving as flutes dividing the cutting edge and trailing edge of each adjacent blade. Each blade may also include more than one segment arranged along its length, the segments coupled by deformation points. The expandable reamer may be used for cutting a cavity in a bone or other structure that is larger than the diameter of the entry point into the bone and greater than the diameter of the contracted reamer.

Glass Processing Method Using Laser and Processing Device

A glass processing method comprising steps (i), (ii) carried out in the order mentioned. In step (i), a laser pulse (11) with a wavelength λ is condensed by a lens and is applied to a glass plate (12) to form an altered portion (13) at the portion, irradiated with a laser pulse (11), of the glass plate (12). In step (ii), the altered portion (13) is etched by using an etchant having an etching rate larger for the altered portion (13) than that for the glass plate (12). The laser beam used includes the following conditions: The pulse width of a laser pulse (11) ranges from ins to 200 ns, with a wavelength λ being up to 535 nm. The absorption coefficient of the glass plate (12) at a wavelength λ is up to 50 cm−1. A value obtained from a lens focal distance L (mm) divided by the beam diameter D (mm) of the laser pulse (11) when entering the lens is at least 7.

Mounting arrangement for inflatable seals

A closure seal for doors, hatches and the like comprising a pneumatically inflatable sealing element of generally known configuration housed in a specially constructed channel-shaped retainer. The sealing element comprises a flat, relatively stiff base portion of predetermined width and a flexible portion comprising spaced apart side walls, joined with the base, and an outer wall joining with the side walls to form a hollow expandable section. The base forms shoulders where it joins with the side walls. A retaining channel, formed of sheet metal and of generally U-shaped cross section, receives the sealing element and is formed with longitudinally spaced apart, opposed, inwardly projecting elements forming longitudinally spaced apart constrictions of slightly less width than the base of the sealing element. The sealing element is inserted in the retaining channel, with the base of the element being forced through the constrictions, and thereafter is retained in the channel by engagement of the shoulders of the base by the spaced apart projection pairs.

Apparatus and method for manufacturing abrasive tools

A compression molding apparatus and method for the manufacture of abrasive layers for abrasive tooling which provides a compression mold space defined between an inflexible wall surface and a flexible wall surface. The apparatus and method of the present invention is particularly well suited to making annular or hollow cylindrical shaped abrasive layers of novel configurations during a single mold cycle useful for grinding wheel and the like, as well as other shapes such as laps, wherein the flexible wall expanded with fluid pressure provides a highly uniform distribution of pressure against the surface of the mold composition being formed. In an annular configuration, the flexible wall is used to radially direct pressure against a molding composition disposed in an annular configuration wherein the axial length of the annular mold shape formed may be many times greater than priorly obtained by the prior art means.
