Turnstile Abstract: A broadband turnstile antenna system is provided by four triangular fan-shaped radiating elements spaced about a vertical tower. Each of the triangular radiating elements is constructed and arranged to present a minimum of vertica...
Turnstile Abstract: A circularly polarized antenna system adapted to provide an omnidirectional pattern over a fairly broad band of frequencies when mounted to a sizable tower is provided by four turnstile fed horizontally polarized radiating element...
Turnstile Abstract: A turnstile mechanism comprising a rotatable hub adapted to be driven by a person using a turnstile, the hub being connected to (or incorporating) a disc formed with a number of stop surfaces which are engageable by a stop member...
Turnstile Abstract: A turnstile construction wherein arms normally block the path of movement of persons passing through the turnstile. The arms are engaged when authorized passage is available, and this results in movement of the arms either by the...
Turnstile Abstract: A U-shaped frame is secured to a pair of spaced fence posts, and the frame has yoke members which secure the U-frame at the top and the bottom to the fence posts. A one-way gate or turnstile is provided by rotatable members on the...
Turnstile Abstract: A truncated conical member of conductive material is mounted forward of a pair of crossed dipoles, the legs of which are inclined toward a reflector. The pair of dipoles cross orthogonal to each other at the dipole centers with th...
Turnstile Abstract: A multioctave, multifunction antenna system including three planar terraces each having four symetrically placed individual turnstile arrays. A first terrace includes turnstile arrays of a first relatively large size, the second t...
Turnstile Abstract: A twin-gate type turnstile in which the central barrier thereof is provided in the form of vertically staggered rows of arms extending between an opposed pair of posts, with at least terminal lengths of the fixed arms, i.e., the l...
Turnstile Abstract: The invention provides a rugged, practical, and readily portable turnstile goal, having two to five relatively large sized paddle type elements of grided construction, a simple, rugged, and concealed turnstile rotary friction cont...
Turnstile Abstract: A new turnstile is provided which is constructed from a minimum number of different extruded components and includes an improved turnstile control mechanism. The turnstile is comprised of a plurality of upstanding, spaced mounting...
Turnstile Abstract: It is a question of bringing resiliently and successively the arms of a turnstile to their position obstructing a passage to be controlled, and for this a rotary cam 1 in the shape of a star is used interlocked with the rotary ass...
Turnstile Abstract: A four element antenna turnstile tracking system which outputs an azimuth error signal, an elevation error signal and an independent sum signal. Three tracking antennas are disposed triangularly at the vertices of a triangle and t...
Turnstile Abstract: A safety turnstile for permitting entry of the public in one direction and preventing exit of the public in the opposite direction comprises a rotary head which can be removed from the turnstile support post in a rapid and simple...
Turnstile Abstract: A revolving door includes an elongated pivot column having a plurality of integrally formed first grooves extending longitudinally therealong at equidistantly spaced intervals therearound. A plurality of barrier members are provid...
Turnstile Abstract: A turnstile system used to meter the entry of persons into or out of an area through a passageway includes a first cabinet defining one side of the passageway with a turnstile hub rotationally mounted in the first cabinet. The tur...
Turnstile Abstract: A rotary gate control assembly includes a pivot rod on which the rotary gate is adapted to rotate and a cam having a continuous cam surface with a plurality of lobes disposed at spaced intervals therealong for defining a plurality...
