The invention is directed to a low-temperature cooler using dry ice as a cooling agent. The cooler has two compartments, one for the dry ice and one for chilled storage. The cooler self-regulates via an aqueous filled temperature-regulating valve to maintain a desired temperature in the storage compartment such that the products stored therein are stored at an optimum temperature. Upon achieving a predetermined temperature in the storage compartment, the valve closes, thereby maintaining the predetermined temperature in the storage compartment.

The liner hanger assembly seals with casing 8 and supports a liner 98 within a well. The tubular liner hanger 48 and a tubular expander 40 may be position downhole on a running tool at a desired depth along the casing string 8. An actuator assembly 6 may forcably move the tubular expander 40 into the tubular hanger, expanding the liner hanger to seal and secure the hanger against the casing string 8. After the running tool has been removed, a seal nipple may be sealed to the sealing sleeve of the tubular expander. A selectively releasable clutch 73 is provided for allowing rotation of the liner to rotate the liner with the running tool, and thereafter to disengage and release the running tool from the set liner hanger.

An image display system for viewing an electronic image and an external sight simultaneously, which includes image display units which have an individual controller for outputting image signals to a display unit. The display unit enables a switching operation with a predetermined operation mode from a plurality of operation modes, including a mode for indicating the image signals output from the individual controller. An external control device outputs mode control signals which address the operation mode of the display unit and are received by an external control terminal. A mode exchanging switch specifies a condition of the mode control signal. A detection unit detects whether the external control terminal is connected to a connector capable of outputting a mode control signal. The individual controllers are connected to the external control terminals in turn so as to couple the controllers to the external control device in series. The operation modes can be collectively and forcibly controlled by the individual controllers on the basis of mode control signals received by the external control unit.

A fiber-optical, wavelength selective switch, especially for channel routing with equalization and blocking applications. The input signals are converted to light beams having predefined polarizations (41). The beams are then laterally expanded (43), and then undergo spatial dispersion in the beam expansion plane. The different wavelength components are directed through a polarization rotation device, pixilated along the wavelength dispersion direction such that each pixel operates on a separate wavelength. Each beam is passed into a pixilated beam steering array (48), for directing each wavelength to a desired output port. The beam steering devices can be MEMS-based or Liquid crystal-based, or an LCOS array. When the appropriate voltage is applied to a pixel and its associated beam steering element, the polarization of the light passing through the pixel is rotated and the beam steered to couple to the selected output port.

The covers stack together in two different ways. First, the covers can be stacked into an “aligned” stack. The aligned stack provides structural rigidity for bulk handling during manufacturing. Second, the covers can be stacked into a “locked” stack. The locked stack provides even more structural rigidity than does the aligned stack and is useful when storing unused covers. The cover includes a first closure portion, an engagement portion, and an alignment portion. The base includes a second closure portion.

A fiber-optical, wavelength selective switch, especially for channel blocking applications. The input signal is converted to light beams having predefined polarizations relative to the plane in which optical manipulation of the beam is performed. The beams are then preferably laterally expanded in this system plane only, and then spatially dispersed in the beam expansion plane, preferably by means of a diffraction grating. The light is directed through a polarization rotation device, preferably a liquid crystal cell, pixelated along the wavelength dispersive direction such that each pixel operates on a separate wavelength. When the appropriate control voltage is applied to a pixel, the polarization of the light signal passing through that pixel is rotated. The wavelength dispersed beams from all of the pixels are then recombined, and are passed towards a polarization selective device, aligned such that only selected polarization components are transmitted out of the switch.

A hand held exercise device for providing a user with a portable workout. The device may generally comprise a central handle diametrically disposed within and spanning across a ring element having a toroidally shaped inner chamber. Internal bumpers within the inner chamber act to limit the range of motion or travel of at least one mobile element within the inner chamber. Rotational forces imparted by the user upon the handle cause movement of the at least one mobile element that is responded to and countered with user muscle flexion. In this manner, a user may perform a satisfactory workout by continually imparting and then resisting rotation force in alternating clockwise and counterclockwise directions.

A personal air conditioning apparatus includes a centrifugal fan received within a scroll casing. A container mounted to the inlet of the scroll housing is provided for receiving and holding a coolant member. The scroll casing is supported upon a base enclosing two liquid reservoirs and a battery compartment. A liquid atomizing device fed from one of the reservoirs dispenses liquid droplets into air flow from a discharge passage. A channel extends between the container and the other of the reservoirs for draining away condensation formed on the coolant member. The scroll casing defines the discharge passage, which has a cross-sectional area that increases toward an outlet at an end of the scroll casing. Axially opposing faces of the discharge passage are divergent, and the cross section of the discharge passage adjacent the outlet has a shape elongated substantially in the axial direction. The inner end of the container lies above the scroll casing and a surface bounding the lower side of the discharge passage is inclined upwardly from the inlet toward the outlet. The coolant member may be a chilled beverage can and, when the fan is not operating, cooled air drops into the fan where it is retained.
