Abstract: A tethering system having an elongate flexible element, with a length, and an anchoring system. The anchoring system has a block defining first and second surfaces. The anchoring system further includes (a) a first anchoring assembly for bearing a first portion of the elongate flexible element against the first surface with the first anchoring assembly in a first state to maintain the first portion of the elongate flexible element substantially fixed against movement relative to the first surface, and (b) a second anchoring assembly for bearing a second portion of the elongate flexible element against the second surface with the second anchoring assembly in a first state to maintain the second portion of the elongate flexible element substantially fixed against movement relative to the second surface. The first anchoring assembly is changeable selectively between its first state and a second state wherein the first portion of the elongate flexible element can move relative to the first surface.

At least one of a) a first discrete part of the cord is repositionable relative to a second discrete part of the cord and b) at least a part of the housing is repositionable relative to a support on which the housing is mounted in an operative position to control twisting of the cord about the length of the cord by reason of turning of the connector.

Abstract: A lasso for securing an object to be monitored. The lasso has a flexible cord with a length and first and second free ends, and a connector having a body with at least one opening therethrough. The portion of the flexible cord between the first and second free ends is directed through the at least one opening so that the connector and the portion of the flexible cord define a closed first loop with an effective diameter. The portion of the flexible cord is configurable to be generally U-shaped with a base and first and second legs which each project through the at least one opening. At least one of the first and second legs is movable relative to the fitting so that the effective diameter of the closed first loop is variable. The first free end of the flexible cord is directed through the closed first loop so as to define a closed second loop with an effective diameter that is variable by selectively oppositely moving the flexible cord through the closed first loop.

Abstract: A voltage protector and grounding bar arrangement is provided for use with a telephone terminal block having at least two rows of terminals which are spaced apart from each other so as to define an elongated channel therebetween. A housing has incorporated therein a voltage suppressor, terminal contacts for mating with the terminals of the terminal block, and a ground contact for mating with a grounding bar disposed within the channel of the terminal block. Plug-in carrier devices are adapted to be mounted in a plug-in manner upon the housing, and the carrier devices may comprise fuse-type current limiting devices, positive-temperature-coefficient (PTC) current limiting devices, or bridging clips. The housing may accommodate a single plug-in carrier device, or dual plug-in carrier devices whereby protection is afforded to the circuit-to-be-protected in a multitude of directions.

Abstract: A communication circuit protector is provided for use with connector blocks in telecommunication equipment. The circuit protector includes a uniquely-designed two-piece interfitting housing for accommodating a variety of protector circuits to provide different kinds of over-voltage and/or overcurrent protection while using the same housing. The housing is adapted to plug-in or to be inserted into the connector clips of a Krone-style terminal block. The side of the housing is provided with means for retaining a side ground contact which is connectible to one of the grounding tab members of the grounding bar of the connector block. In a preferred embodiment, the protector circuit includes a diode bridge rectifier, a pair of voltage suppressors, and a pair of sneak current fuses.

The protector comprises an externally accessible fuse compartment having fuse contact pairs. A removable fuse holder capable of locating a fuse within the fuse compartment is provided. A fuse holding element is disposed on the removable fuse holder capable of holding fuses with respect to the removable fuse holder and positioning the fuse in engagement with the fuse contact pairs.

Abstract: A fuse having a rated current for protecting electric or electronic circuitry comprises a body having a blow chamber. A fusible element is contained within the body and extends through the blow chamber. A contact is disposed on the body electrically connected to the fusible element for making an electrical connection between the fuse and the circuitry. The blow chamber is sealed around the fusible element so that thermal energy in the fusible element can increase within the blow chamber for causing the element to open when an elevated current is applied to the element. The blow chamber is sufficiently sealed around the element for retaining a pressure created therewithin by vaporization of a portion of the element; that pressure is sufficient to cause an arc produced by fusion of the element to extinguish. The body is of sufficient strength to contain the pressure within the blow chamber for allowing the fuse to fail gracefully.

Abstract: A thermostat top part is mounted to a valve housing for rotation relative thereto and is axially removably secured thereto. The thermostat top part has a retaining ring surrounding and rotatable relative to a hollow cylindrical base foot. A clamping element is mounted by the base foot for radial movement between a position abutting against a clamping face of the valve housing that is tapered axially toward the housing abutment face in a radial inward direction for retaining the top part on the valve housing and a radial outward position permitting the thermostat top part being axially removed from the valve housing. A torsion spring resiliently urges the retainer ring to rotate in a direction for moving the clamping element radially inwardly.

Abstract: A fuse assembly has snubber/indicators which are visible through translucent lenses provided within the fuse cover, for indication and inspection of the fuse operability. The snubbers provide a shearing load upon the fuse filament so as to more positively separate the fuse segments of a ruptured filament, which snubbers may also envelop and insulate the conductor posts and separate the ruptured fuse elements so as to inhibit arcing within the "blown" fuse.
