The handrail guide is suitable for use on very thin escalator balustrades, such as are typically made of glass or the like. The handrail-contacting-track surface is formed from a low friction plastic material. The plastic track member is affixed to a mount base which clips onto the balustrade, and the track is reinforced by a recessed steel strip plate fastened directly to the base through the track.

The steps of the escalator move along a curved path which has a fixed constant radius when viewed in plan. The step chain also follows the constant radius path and thus its effective length must vary at different locations along its path of travel in order to keep the step rollers on their constant radius tracks. The effective length of the step chain is varied using an eccentric pivot cam at chain link connections spaced along the chain whereby the degree of overlap of adjacent links can be changed by controlling the path along which cam actuating rollers travel. The cam actuating rollers control operation of the eccentric pivot cam link connections.

A system and method for increasing accuracy of transmitter power detection over a larger range of output power levels wherein a diode detector is followed by a series cascade of 2 op amps. The first op amp functions as a differential/buffer amplifier, which improves temperature performance. The second op amp has two selectable gain factors. The output of the second op amp is routed to the ADC. A single control can is connected to a controllable switching device that configures the second op amp for high gain or low gain.

A time measurement circuit includes N time stamping units that each includes a dual sinusoid interpolator for achieving high timing resolution. The time measurement circuit is capable of time stamping input signals at a high re-trigger rate, and is thus well suited for quickly measuring the timing jitter of test signals in automatic test systems.

An apparatus for inserting filler elements such as sealing plugs within electrical connectors includes a threaded connector, a serrated grip, an ergonomic handle and a hollow tube for receiving filler elements of various sizes. The hollow tube assembly may be interchangeable with variously sized hollow tubes to accommodate the various sized filler elements.

FIG. 1 is a top perspective view of an adaptor for a planter, according to the present invention, with the environmental structure of a planter and lid exploded from the adaptor for planter. FIG. 2 is another top perspective view thereof, with the environmental structure of a planter and lid coupled to the adaptor for a planter. FIG. 3 is a front perspective view thereof. FIG. 4 is a front cross-section view taken along line 4-4 in FIG. 6. FIG. 5 is a left view of the adaptor for a planter. The right view is a mirror image of the left view. FIG. 6 is a top view thereof; and, FIG. 7 is a bottom view thereof. The broken line showing of the planter and the lid in FIGS. 1 and 2 is included for the purpose of illustrating environmental structure only and forms no part of the claimed design. Portions of the adaptor for a planter shown in broken lines form no part of the claimed design.
