Title: Echo location system transmitting and receiving  component signals of known initial time interval  for determination of angular information

Abstract: ABSTRACT            This invention relates to a method for ascertaining for one or more targets information about the positions and velocities of the targets by using at least one transmitter and at least one receiver stationed at known relative positions in a medium having a known signal propagation velocity.  Each transmitter transmits concurrently at least one component signal of known initial time consisting of at least two member signals, the time intervals between member signals being initially known.  The concurrent component signals are separable.  Each target reflects each component signal to each receiver.  From each received signal the component signals are separated.  From the component signals member signals reflected by each target are identified.  For each identified member signal its transit time between transmitter and receiver, and the interval time, between member signals of each component signal reflected by each target are measured.  Target velocity components from each measured time interval are produced using the known initial time interval value.  Each measured transit time in each component signal is corrected for determined relative motions between the transmitter, receiver and targets.  The corr-ected transit time measurements in the component signals and the known signal propagation velocity are used to make target range determinations.

Abstract: Abstract of the Disclosure A ski traction device particularly, but not exclus-ively, for use with a cross-country ski.  The traction device comprises a unitary base plate which is securable to a top face of a ski.  A traction element cooperates with the base plate and has at least one traction pin, a clamp head and a seat section.  The traction element is hingeably retainable by the base plate for pivotal movement to permit arcuate dis-placement of the traction pin adjacent a side of the ski when the base plate is secured to the top face of the ski.  The seat section restricts the arcuate displacement of the traction pin to an axis extending substantially transverse to the plane of the top face of the ski.  A catch is formed by an upstanding flexible section of the base plate for releasably retaining the clamp head therein.  A spring action is provided with the traction element to urge the clamp head away from the catch of the base plate.

Abstract: ABSTRACT OF THE DISCLOSURE        At the remote end of a Type C track circuit, the conven-tional diode and the winding of a power transfer relay connected in multiple are connected across the rails over a transfer relay front contact.  This transfer relay and the track relay at the near end are normally energized by the same half cycle of track current from the alternating current (AC) source. If the AC source fails, a track battery is connected across the rails at the remote end in series with the diode end transfer relay multiple network over a transfer relay back contact. The diode is so poled that the track relay is energized from the track battery with the same polarity as the rectified alterna-ting current and does not release during the transfer operation. The diode bypasses substantially all track battery current away from the transfer relay. When the AC source is restored, the transfer relay is initially energized by the rectified alterna-ting current through a low impedance capacitor, connected in multiple with the track battery and transfer relay back contact, and picks up to restore normal track circuit operation.
