A gas flow regulator valve is provided with a metering valve and filter assembly including a drawn, generally cup shaped, or hat shaped filter element having a substantially flat end panel, a generally cylindrical sidewall and an open end opposite the end panel. An integrally formed flange, or rim, is formed around the open end and projects outwardly therefrom to provide means for mounting the filter, in a fluid-tight relation, in the metering valve assembly body. The filter is formed from a substantially planar disc-shaped blank of a multilayered screen material in which the respective layers are welded, or sintered, to one another to form a rigid, porous filter medium. The blank is shaped by a cup drawing operation of a filter mesh made of layers of woven smooth, corrosion resistant, fine gauge, high strength metal.

An electrical connector for an electrical connection is disclosed, comprising a female receptacle to connect to either a male shorting cap or a male plug. The male plug and female receptacle can be fastened to a standard knockout in a light fixture. The male plug and female receptacle have alignment means such that they can only fit together one way, and once together are positively connected by means of a twist-lock ring. The male plug is connected to the female receptacle by aligning the two fins to the two corresponding grooves, and pushing inward such that the protrusions of the female receptacle pass through the indentations in the ring of the male plug. The twist-lock ring is turned and the nubs on the protrusions engage the notches of the female receptacle, creating a removable twist-lock ring.

An interconnected heated patio stone and system are disclosed, the stone consisting of a durable, heat-transmitting upper layer, and an insulating lower layer, a heating cable running within the stone, and having two interconnections at the edge of the stone. The interconnection has a bracket to connect with the cable, a receptacle for joining electrically to a bridging connector, and an electrical linkage making an electrical connection available. Each stone is connected with another by a bridging connector, which contains an articulated wire, and has a basin and cap at each end for electrically joining, in a sealed manner, with the receptacle. The system consists of two or more stones interconnected using bridging connectors, the whole system also connected to a power source.

A pierceable cap 11 may be used for containing sample specimens. The pierceable cap 11 may prevent escape of sample specimens before transfer with a transfer device 43. The pierceable cap 11 may fit over a vessel 21. An access port in the shell of the pierceable cap 11 may allow passage of a transfer device 43 through the pierceable cap 11. At least one frangible layer 215, 216 may be configured with cross slits 506 in a particular cross slit geometry. The cross slits 506 may contain an openable portion 644 or be covered by a thin membrane 645. The shell 610 and frangible layer (s) 215, 216 may be integrated into a one piece cap 601, or be separate components 634. The membrane on which the cross slits 506 are placed can be flat or contoured to guide the transfer device 43 to the cross slits 506.

A golf pitch mark repairer (101) is adapted to be removably retained on an extremity of a golf club, thereby allowing a golfer to utilize the reach afforded by the golf club to facilitate repair of the pitch mark. The pitch mark repairer (101) comprises a sleeve (103) for receiving the golf club extremity, and a retaining mechanism in the form of resilient tabs (111a, 111b) adapted to resist movement of the golf club relative to the pitch mark repairer (101). The golf club extremity is inserted with a sliding collar (117) positioned towards closed end (105) of sleeve (103). The sleeve (103) comprises windows (116a, 116b) through which respective portions of resilient tabs (111a, 111b) are urged to protrude outwardly when the golf club extremity is inserted. Thereafter the sliding collar (117) is engaged by sliding it along the sleeve (103) towards its open end (107). This acts to urge tabs (111a, 111b), and in particular respective valley portions (114a, 114b) thereof, into tighter engagement with the putter handle, resulting in a strong grip on the putter handle.
