A holding assembly is affixed to the ground terminal within the hollow housing and is adapted to receive a surge arrester therein. The surge arrester may be a three terminal device or a pair of two terminal arresters with one electrode of each connected to the ground terminal and each one of the other electrodes being connected to a line terminal.

Abstract: A weatherproof network interface module for providing connection between a customer's equipment and the telephone company owned portion of the customer loop includes an overvoltage protection device disposed therein in addition to the circuitry which provides a prescribed line test termination impedance having particular characteristic signature to the telephone central office when a continuity test is made on a subscriber line and may include an illumination device and test switch for indicating when the telephone company owned portion of the customer loop is in operating order, or may include a device for connecting or disconnecting the telephone company owned portion of the customer loop from the customer loop portion wherein all of terminals are weatherproof (protected from the environment).

Abstract: A miniature back-up overvoltage protection apparatus for use on an overvoltage protection device includes a housing adapted to be removably mounted on the first and second terminals of an overvoltage protection device. A dielectric is disposed within the housing and is sandwiched between two electrically conducting members done of which is in contact with one end terminal of the overvoltage protection device. A unitary clip is adapted to removable retain the overvoltage protection device and to urge a pair of back-up overvoltage protection apparatuses against the distal terminals of the overvoltage protection device with the clip making electrically conducting contact with the third terminal of the overvoltage protection device, the second conducting member and to the ground terminal of the telephone line system.

Abstract: Aggregate pigment products made of low-refractive-index raw materials, in which pigmentary, subpigmentary and nonpigmentary components are cemented intrinsically with the aid of in-situ synthesized complex microgels.

Abstract: A seamless filter bag with integral sealing means for use in a filter housing utilizing a filter basket includes an integral sealing means, which is part of a semi-rigid ring member affixed to a filter bag. Upon closing the filter housing cover a complete seal circumscribing the filter basket and filter housing cover is provided.

Abstract: An apparatus for collecting and killing insects which includes a heat source for attracting the insects to a housing, electric conductor means, for connection to a power source, to stun or kill the insects, means for collecting the insects after they are stunned or killed, and means for vacuuming the insects into a collection vessel so that they can be transported away from the apparatus and disposed. The collection vessel may be filled with oil to assure suffocation of the insects. The subject invention also can be employed in combination with conventional appliances having a heat producing element so that insect infestations attracted to the appliance can be easily disposed of by employment of the subject invention.
