Abstract: The present invention relates to a train vehicle speed control apparatus which recognizes a change in one of the acceleration rate or the deceleration rate of a train moving along the track and the control of the train velocity in relation to what distance will be required for a desired operation of the train such as a predetermined decrease in the train speed or a stopping of the train. If the deceleration rate has changed, for example, the fixed physical system limits what control can be exercised and the velocity of the train can be modified to adjust the actual stopping distance used by the train or with a fixed stopping distance desired then the permitted train velocity can be changed.

Abstract: A transportation vehicle for use in a mass transit system is provided with movable guidance wheels operative with a vehicle restraining guide beam included with the vehicle roadway, and which guidance wheels can be selectively moved into engagement or out of engagement with the guide beam to direct the vehicle onto one or another vehicle roadway.

Abstract: A Philodendron plant of very compact rosette form having thick narrowly ovate to elliptic leaves, the leaves being dark-brick red becoming dark-reddish-green when mature. The petioles are black-red, short, thickened and prominently winged.

Abstract: A self-heading Philodendron plant having uniquely shaped leaves with pronounced lobes that are distinctly hooked. New leaves are moderate reddish brown. Overall color of the plant is reddish to rich-green with reddish brown colored petioles.

Abstract: The disclosure hereof is of a very compact, self-heading Philodendron plant of unusual density of growth. The plant is very stocky, producing an abundance of off-shoots from the crown, leaves are emerald green and are thick and glossy, having short thick petioles.

Abstract: There is disclosed a compact semi-self-heading Philodendron plant of unusual growth habit, since it will remain stocky with thick leathery emerald green, round leaves on short petioles with minimum forcing, being self-heading likewise and if grown on a pole and fertilized frequently, it becomes a striking totem specimen, the growth as a totem being slow, this providing a desirable feature since the plant will not stretch or become leggy thereby.

Abstract: There is disclosed a stocky, compact self-heading Philodendron plant of unique color, having new leaves of bright orange, which when the leaves mature change colors from orange to apricot, to yellow green to pale or medium green, pinkish red petioles adding to the overall distinctive color of the plant wherein the petioles are short and stocky averaging six to seven inches in length, whorls of twelve inch long by eight inch wide leaves that are elliptic to ovate in shape coming from the crown, a relatively high indoor light intensity and moderate temperature being needed for good color.
