A furniture glide includes a ferrule having an upstanding cylindrical side wall defining a ferrule opening for receiving a furniture leg. Four substantially equidistantly spaced, upstanding ribs extend laterally inward from the side wall to a guide surface. The diameter of the circle formed by the four guide surfaces is substantially the same as that of the ferrule opening. A clip mounted in the ferrule has a pair of upstanding opposed clip arms. A plurality of prongs extend radially inward from...

A hold circuit arrangement for a telephone, wherein the telephone is coupled to an extension release circuit of an external telephone, the hold circuit comprising an input control terminal; a tri-state input device used for generating a signal for the input control terminal; a power supply used for providing a high impedance level for the input control terminal; a hold button circuit used for allowing a hold button of the telephone to convert a status of the hold circuit through the tri-state in...

A hold-down clip for holding panels on inverted T-shaped members in a suspended ceiling characterized by a U-shaped one-piece member having a bight portion interconnecting two leg portions. Each of the leg portions, along an edge, has an inwardly bent flange with a plurality of teeth aligned with the teeth in the opposite leg portion and each of the leg portions has a foot portion adjacent the free end for engaging and holding the panel on the flanges of the T-shaped member. To increase the rigi...

A sample and hold circuit made entirely of NPN transistors, capacitors and resistors uses double emitter-follower transistors for gating an input signal onto a charging capacitor. A transistor connected in parallel to the first of the emitter-follower transistors is controlled to conduct blow-by current away from the second emitter-follower transistor in the hold state. A step voltage is applied to the charge capacitor in the hold state to prevent turn on of the emitter-follower transistors. The...

The optical hold unit (100) of the present invention includes an optical modulator (108) that has an electrical input, an optical input, and an optical output. A 1.times.N optical splitter (106) is also provided that has an optical input and N optical outputs. In addition, N optical paths (112) are individually coupled to the N optical outputs and carry one of the N output signals. Each optical path has an associated propagation delay. Optical delay elements may be located in any of the N optica...

The invention provides an on-hold switching device that permits a subscriber to be engaged in other activities through a telephone network while being placed on-hold by another party. When placed on-hold, the on-hold switching device disconnects the subscriber from the other party and connects the subscriber to the telephone network so that the subscriber may engage in other activities. The on-hold switching device monitors the signal bus connected to the other party to determine whether the on-...

A hold down fastener clutching mechanism comprising an inner torque ring having a pair of split outer ring members with angled ends. A sloped surface at one of the angled ends is at a predetermined angle to the fastener axis. The other end of the inner ring member is integrally joined to an adjacent inner ring member which has a pair of rib members. The selected slope (angle) of the angled surface, for the specific material used, determines the amount of prevailing torque provided by the device ...

A horizontal rotary hold down jig for use in horizontally guiding a piece of wood to be cut on one of a portable table saw and a portable router table comprising a spring biased rotatable wheel that can be secured to the table. The spring biasing can be adjusted to provide uniform or enhanced pressure through use of a plurality of substitutable compression springs of varying compressive strength characteristics to laterally stabilize a piece of wood of varying consistency, wood grain angle, feed...

Universal battery hold-down structure particularly including an elongated bolt having a J-shaped lower end for securing the bolt to a battery tray and means to facilitate shortening of the bolt, a chrome plated non-corrosive elongated wing nut having a threaded opening in the lower end thereof for receiving the upper end of the bolt and including a dual external diameter forming an annular abutment adjacent the other end thereof for clamping a battery strap over the top of a battery positioned i...

In order to reduce harmonic distortion, a track and hold circuit comprising a MOS transistor switch, a hold capacitor, and a voltage stabilizer for biasing bulk potential of the MOS transistor switch at a certain voltage is disclosed.
