摘要:
A device assembly (100) has a switch actuator assembly (150) with a sealed interface. The device assembly (100) includes a housing (120) having an opening (126) that provides access to an internal switch (135). A switch actuator (160) selectively actuates the switch (135) through the opening (126). The switch actuator (160) includes a seal (164) that is disposed around the opening (126). An external actuator cover (180) includes a seal support member (185) that positions the seal (164) against a seal mount (128) about the opening (126), when the actuator cover (180) is depressed.
摘要:
A radio frequency switch assembly (120) is mountable between an antenna port (110) and a detachable antenna (130) of a radio communication device assembly (100) to provide an interface for a radio frequency accessory. The switch assembly (120) has a radio interface port (123), a radio frequency accessory port (125), and an antenna interface port (127), and associated contacts (207, 216, 223). A mechanical switch alternatively interconnects the radio interface port (123) with the radio frequency accessory port (125) or with the antenna interface port (127). Preferably, the switch includes a conductive probe (213) that continuously engages the radio interface port contact (207) while being slidable to electrically interconnect with the antenna interface port contact (223) or with the radio frequency accessory port contact (216).
摘要:
This invention is related with a procedure for the obtention and purification of 2-(2-nitrovynil)-furan in a step of reaction starting from furfural and nitro methane using isobuthylamine as a catalyst and activated coal as an adsorbent, achieving a product with pharmaceutical quality. This technology appreciably reduces the environmental impact through eliminations of the gassy residual from the system through absorption in water. The pharmaceutical composition proposed in this invention contains 2-(2-nitrovynil)-furan and presents a potent action against Coccidia at low concentrations.
