Abstract: Disclosed are passive reflector radio communications systems, such as for UHF frequencies or greater than UHF frequencies, and related deployment systems and devices that provide underground communications. Embodiments of the system include reflector elements to provide passive radio communications, structural frameworks to support and orient the reflector elements, methods for calculating reflector size, shape, and position corresponding to a desired wavelength, and deployment methods and devices to install the communication system at a desired location. The passive reflectors can be placed in a folded or otherwise compact mode, for transport into underground tunnels. Once at the desired installation location, the system can be installed, with the reflectors positioned appropriately for the radio frequencies used at the location.

Abstract: A rotary actuator includes a central housing; an output shaft that extends through the central housing; a vane that is mechanically coupled to the output shaft and divides the central housing into a first chamber and a second chamber; and a flow control mechanism that is moveable within the central housing and including a high pressure port and a low pressure port for communicating hydraulic fluid into and from the first and second chambers. The flow control mechanism is moveable to position the high pressure port and low pressure port relative to the first chamber and the second chamber for communication of the hydraulic fluid, thereby generating a pressure differential across the chambers. The vane rotates within the central housing in response to the pressure differential, and rotation of the vane drives the output shaft. A motor is configured to receive control signals to drive the movement of the flow control mechanism.

Abstract: A horizontal non-barrier pressure vessel including a first chamber and a second chamber that are separated by a divider. The first chamber includes a first end proximal an opening, a second end distal the opening, and an uppermost surface that extends horizontally along the length of the first chamber or is inclined upwardly from the first end to the second end. The second chamber operatively adjoins the first chamber at the second end opposite the opening. A flow passage extends across the divider and enables fluid communication with the first chamber at an upper region of the second end and with the second chamber at a lower region. The divider may include vertically oriented bottom and top baffles being spaced to form the flow passage. The pressure vessel may include a plurality of segments and/or chambers sequentially arranged along a horizontal course.

Abstract: A punch-through gift container for use in party and game play environments providing in one embodiment an enclosed container comprising a rigid backwall (40), rigid sidewalls (50 and 51), and an internally positioned matrix of interlocking rigid partitions (30 and 32), creating within the container a plurality of compartments (02). The front wall of the container comprises a thin fungible wrapper (10) affixed to the front of the container, with a plurality of aiming targets (20) adorned on the exterior of the wrapper to indicate the center of each compartment contained therein. Gifts placed within the compartments of the container are retrieved from the chosen compartment by punching or otherwise breaking the wrapper through the aiming target corresponding to the chosen compartment. Other embodiments are described and shown.

Abstract: A hydraulic anti-vibration support comprises at least one elastomer spring body made of a high temperature-resistant material which connects a first rigid strength member and a second rigid strength member. The first rigid strength member includes a piston which comprises a rod terminated by an end member, and a second rigid strength member has an opening which is traversed by said piston. A liquid-filled module is mounted inside a casing which is secured to the second rigid strength member, and includes a working chamber defined in part by a substantially dome shaped elastomer wall which has a central area in contact with the end member of the piston without any mechanical securing. Preferably, the high temperature-resistant material comprises silicone and is in non-adhesive contact with the first and the second rigid strength members.
