摘要： This is concerned with a method and apparatus for sensing and/or finding objects along railway track, for example a tie, so that work may be done in relation thereto. More specifically, the subject matter is concerned with a method and apparatus for finding ties on a step-by-step basis and performing work in relation thereto, for example tamping between the ties or driving spikes through the holes in tie plates into the ties, or the like.

摘要： This invention relates to apparatus for surveillance, counting and guard purposes of the kind in which emitters emit electrical beams or radiation or jets of water to appropriately responsive reception means, one receiver being associated with one emitter, the arrangement being such that when a body representing a triggering occurrence enters the beam path between an emitter and a receiver, and thus interrupts at least one of said beam paths, it causes an apparatus for interpreting the triggering occurence to respond via the receiver or receivers thus affected, so that the interpreting apparatus will then halt an operation taking place in a machine, set off an alarm or cause the triggering occurrence to be counted. According to the invention, one receiver and one emitter are connected together in each case to form an independent channel: all the similarly formed channels constitute a ring circuit such that, as a result of the beam paths being suitably arranged, the receiver in each channel responds only to radiation foreign to its channel coming from the emitter of a channel adjacent to it in the ring circuit in the form of the latter''s own radiation: the circuitry for each channel is such that its emitter is caused to produce radiation for as long a time as its receiver is not receiving foreign radiation but on the other hand emission is interrupted for the time that the receiver receives foreign radiation: an interpreting apparatus is connected to the ring of channels which, when at least one of the beam paths is interrupted by a triggering occurrence, responds by interpreting a transition on the part of the circuit from its dynamic operational state to a static state.

摘要： A bundle of stiff, resilient strands form a flag to be attached to the top of a grade stake for use in construction work such as road building. The cluster of strands are folded into a bight and held in two loops of a metal strip which also has a large loop which may either encircle a large nail or be driven into a wooden stake without splitting the stake.
