Abstract: A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.

Abstract: Liquid-core capsules (10) for pest control are provided, wherein the liquid-core capsules (10) have an aqueous core (11) and a diffusion-inhibiting, functional outer shell (13). The core (11) contains at least one pest control agent. The outer shell (13) contains at least one attractant for the pests.

Abstract: A computer implemented method of playing a wagering game is disclosed. A base game bet is placed on a base game, results of the base game being resolved according to a first set of game rules. In the method, a side game bet is placed on a side game while participating in the base game. One or more of the results of the base game are used as inputs to the side game, with results of the side game being resolved based on the inputs according to a second set of game rules.

Abstract: A signalling device (10) adapted to make a percussive sound, for example, under water. The signalling device (10) may be attached to a pressurized fluid source, such as a diver's compressed air supply, the device (10) including: a housing (12) having a passageway (22), at least in part, for communication with the fluid source; a valve member (34) located in the passageway (22) and movable between a closed position in which it substantially blocks the passageway (22), and an open position in which fluid may flow through the passageway (22); biasing means (42), such as a spring, biasing the valve member (34) towards the closed position, wherein the valve member (34) reciprocates between the open and closed positions when a pressure difference above a set value exists on either of the valve member (34) to produce a perscussive sound.

The signalling device (10) may be attached to a pressurised fluid source, such as a diver's compressed air supply, the device (10) including: a housing (12) having a passageway (22), at least in part, for communication with the fluid source; a valve member (34) located in the passageway (22) and movable between a closed position in which it substantially blocks the passageway (22), and an open position in which fluid may flow through the passageway (22); biasing means (42), such as a spring, biasing the valve member (34) towards the closed position, wherein the valve member (34) reciprocates between the open and closed positions when a pressure difference above a set value exists on either of the valve member (34) to produce a perscussive sound.

Abstract: A knock-down cabinet including a rear wall having forward projecting side flanges, a top wall having downward projecting side flanges, and a pair of opposed side walls having inboard projecting connector flanges for receiving the respective side flanges of the rear and top walls in an assembled position. The cabinet also includes a front door frame assembly having special shoulder bolt and slot connectors for assembly upon the front edge portions of the side walls, and one or more shelves received within the cabinet. The entire assembly of the cabinet is conducted with a minimum number of press-fitted plugs for assembly without tools within a minimum of time by unskilled labor.

Abstract: A hydrophone comprises a microphone pivotally mounted on each end of a gimballed tube. A coiled cable connects each microphone with a housing for a receiver. A tube having an external diameter equal to the inside diameter of the cable coil is inserted partially into the coil. The end of the cable is threaded through a lateral hole in the tube and through the interior of the tube into engagement with the microphone or the housing, as the case may be.
