A dual-interface sewer cap removal device is provided. The device includes a base plate with a first side provided opposite a second side. A first interface is defined on the first side of the base plate. The first interface is designed to engage a slotted sewer cap. A second interface is defined on the second side of the base plate. The second interface is designed to engage a sewer cap. The second interface is structurally distinct from the first interface. An aperture is centrally disposed on the base plate.

Slotted sewer cap removal socket

A sewer cap removal socket. The sewer cap removal socket includes a base plate. The base plate is defined by a first side oppositely disposed of a second side. An upper wall extends from the first side of the base plate. The upper wall forms a first interface. A lower wall extends from the second side of the base plate, opposite of the upper wall. The lower wall defines a second interface. An aperture is disposed in the base plate.

A speaker enclosure may include a speaker enclosure frame with a back wall, a first, inner wall and a second, outer wall extending from the back wall. The first, inner wall may be longer than the second, outer wall such that a baffle attaches to the first, inner wall, but only attaches to the second, outer wall via the first, inner wall and the back wall.

A manually operated self defense device comprising a manually operated pump driven propulsion chamber which can propel either a stream or spray at a potential attacker wherein the self defense device is characterized by the fact that no pre-pressurized gas or irritant canisters are used, and wherein the self defense device irritant or disabling storage container is not refillable by the user, and when used, the first pump action loads the propulsion chamber from a storage container, and thereafter, the propulsion chamber is always primed and ready for instant operation, and in as much as no pre-charged gas canisters are employed, there is no gas leakage, and reliability is greatly improved, resulting in a self protection device which is capable of providing multiple discharges without the loss of operating range, or effectiveness, and which contains an internal safety mechanism designed to prevent the attacker from turning the self defense device upon the user.

A separate canister of propellant is operatively connected to a canister housing an noxious chemical or dye that is activated by a spring loaded trigger normally holding a connecting valve closed. The system is affixed to a cuff made from a fabric that wraps around the wrist of the wearer.

Protective security system

A speaker assembly and its method of operation are described wherein a plurality of drivers are spatially adjustable relative to each other and to a selected critical listening point in order to establish maximum sound coherency for the system. Means for adjustment and calibration of the relative positions of the drivers are provided to facilitate their location upon a mounting sub-assembly, interchange of components within the total speaker assembly, and synchronization of the drivers for one or more desired listening positions within a listening environment. The speaker system preferably includes a low frequency range sub-assembly having one or more drivers supported in fixed relation within the total speaker system, a housing for the low frequency range sub-assembly including selective band-pass energy filtration means for isolating each driver from its enclosure and an internal structure providing increased structural rigidity and reducing non-linear turbulence within the enclosure.

A unit for rapid priming and flow of liquid through the unit is disclosed. The unit comprises a connector for communicating with liquid in a sealed container, the connector having an exit orifice around which is secured one end of a primer tube. The other end of the primer tube is joined to a pooling conduit. The diameter of the primer tube is greater than the diameter of a drop of liquid released from the orifice and the diameter of the pooling conduit is no greater and preferably slightly less than the diameter of the drop of liquid. Multiple units can be joined to a common tube of enlarged diameter which leads into a pooling and dispensing container.

A three dimensional game is provided comprising upper and lower playing fields each divided into corresponding first and second playing areas. Each playing area is provided with the same number of game piece locations, and the upper and lower playing fields are oriented for the first and second playing areas on the upper field to respectively overlie the second and first playing areas on the lower field. Two sets of game pieces are provided each of a number corresponding to the number of game piece locations provided in the two playing areas of one of the playing fields. The game is played by initially placing all of the game pieces in the corresponding one of the two playing areas in the upper field, thus completely filling the corresponding playing area. The players then, in sequential turn, move their respective game pieces into the corresponding playing area of the lower playing field other than by direct movements thereinto from the corresponding upper playing area.
