摘要:
A polarizing film includes a first phase of a first polymer having a birefringence of at least 0.05 and a second phase of a second polymer disposed within the first phase. The index of refraction difference between the first and second phases is greater than about 0.05 along a first axis and is less than about 0.05 along at least one axis orthogonal to the first axis. The diffuse reflectivity of the first and second phases taken together along at least one axis for at least one polarization state of electromagnetic radiation may be at least about 30%. In some exemplary embodiments, the second phase has a refractive index of about 1.53 to about 1.59. In some exemplary embodiments, the second polymer has a glass transition temperature (Tg) higher than the Tg of the birefringent first polymer.

A springless motorized door latch assembly for locking an oven door in a locked and sealed position for purposes of cleaning the oven. A motor and cam cause a latch member to move between three different positions. In one position the latch member prevents the oven door from opening. From this position, the latch member is pulled inwardly so the oven door is in a locked and sealed position. In its locked and sealed position the door may not be opened.

A bellows, spool, and collar system for dispensing projectiles and submunitions with a predictable and uniform pattern is disclosed. The system utilizes projectiles densely packed in a spool. A plurality of spools is packaged in a missile, bomb, or similar tubular device with an energetic bellows actuator between each spool. The energetic bellows actuator expands rapidly to push a spool of projectiles out of the tubular housing. Timing means is provided for each bellows to provide proper axial spacing between spools prior to subsequently timed release of the projectiles.

A portable hoist provides motorized hoisting and coincidental skinning of game animals. The hoist is preferably secured to an existing motor vehicle and is made using an adaptable segmented frame. A top frame portion includes an electric cable winch and may rotate to any orientation to position a hanging animal carcass where desired. A base portion of the hoist includes a pair of clamps which grip a hide portion of the animal. The winch is then used to simultaneously hoist and remove the hide of the animal.

An assembly for locking an oven door mounted on a body of a range and movable between open and closed positions, is provided that comprises a mount bracket adapted to be secured to the range body, with the mount bracket having a base and a cradle protruding below the base and disposed above an oven top wall. A latch member is coupled to the mount bracket for movement relative to the bracket. A locking device is disposed at least partially within the cradle and includes a thermally responsive element and a locking member coupled to the thermally responsive element. A heat transfer member has a first end adapted to be secured to the oven top wall and a second end secured to the cradle, wherein the locking member prevents the latch member from moving from a position where the door is latched and forced against the range body by the latch member toward a position wherein the door can be opened, when the thermally responsive member is actuated.

In general the disclosure relates to manufacturing methods for producing conductive patterns on flexible substrates. For example, a layer of a metal powder composition is deposited onto an adhesive overlaying a substrate. Pressure is applied to the metal powder composition on the adhesive coated substrate web by a die having one or more projections, in order to reproduce a pattern on the substrate. The metal powder is compressed by the projections of the die, thereby densifying the powder and causing it to adhere to the adhesive in a reproduction of the die pattern. The metal powder does not adhere substantially in uncompressed regions, and may be removed. In this manner, a metal powder composition may be densified and adhered to a substrate forming a web of flexible circuit elements, for example, circuit elements such as antennas, resistors, capacitors, inductive coils, conduction pads and the like.
