Abstract: A seismic source apparatus 10 includes body 12, cap 22, actuator 24, and shuttle 26.  Body 12 includes a main chamber 14 that is formed therein and adapted to receive a charge of compressed air.  Actuator  24  is preferably a solenoid actuated valve,  capable of rapidly opening and closing in response to an electrical  signal.   Seismic source apparatus 10 includes a solenoid chamber orifice 38 that is positioned within a fill passage 34 to enable fluid communication between fill passage 34 and solenoid chamber 40.   Solenoid chamber orifice 38 and solenoid chamber 40 are configured to provide a quick burst of high pressure air through actuator 24 when actuator 24 is opened in order to start the shuttle 26 in motion, while restricting the flow of air from main fill passage 34 and main chamber 14 into the actuator 24 so that the pressure in the main chamber 14 remains high enough to emit a suitable bubble, and so that shuttle 26 is not prevented from closing.  A spring chamber 44 containing either compressed air or a mechanical  spring provides  a  closing  force bearing on surface  46  of  shuttle  26.   A shut-off  chamber  68  is circumferentially disposed between shuttle 26 and cap 22, and is adapted to receive a portion of air released from the main chamber 14 during firing to provide an additional closing force on shuttle 26 when seismic source apparatus 10 is fired.   A water sealing mechanism 74 prevents the flow of ambient fluid into shut-off chamber 68 prior to firing.

Abstract: An improved grounding clip connector for positively grounding an insulated conductor to an appliance panel comprises a base section, a first pair of laterally spaced blade members projecting upwardly from one edge portion of the base section and a second pair of laterally spaced blade members projecting upwardly from a second opposite edge portion of the base section, the laterally spaced blade members defining vertical passageways between the pairs thereof for retaining the insulated conductor upon the connector. A spring clip member is integrally formed with the base section of the connector and is substantially C-shaped in configuration so as to cooperate with the base section of the connector in grasping the appliance panel therebetween. In accordance with the improvement of the present invention, the spring clip member is provided with a pair of axially spaced barbs or prong members for engaging the undersurface of the appliance panel, while the base section is provided with a third barb or prong member for engaging the upper surface of the appliance panel. The three barbs cooperate in concert so as to effectively define a pivot mechanism about which the connector can pivot upon the appliance panel. In this manner, should a force be inadvertently applied to the insulated conductor and thereby transmitted to the connector, the pivotal action or movement of the connector will cause the three barbs or prong members thereof to dig into the respective surfaces of the appliance panel with increased biting effects whereby the retention power or pull-off resistance of the connector with respect to the appliance panel is significantly enhanced.

The probe (12) i s placed into contact with the cornea and energy is transformed from the power source  (14) to the eye, through the lid speculum (202) and bac k to the power source (14). The energy from the power supply is focused by a prob e tip (240) that locally heats and denatures the cornea,  and causes a subsequent shrinkage of corneal tissue. A pattern of denatured area s can be created around the cornea to correct the vision  of the eye.
