Abstract: A modulated LIDAR system is disclosed, in which a laser for generating an tical carrier signal and a microwave generator for generating a coded microwave signal are provided. A modulator is further provided for modulating the carrier signal with the microwave signal, whereby a modulated signal is generated. A method of detecting a reflective surface is also disclosed, in which an optical carrier signal is generated, the carrier signal is modulated with a coded microwave signal, the modulated signal is reflected off of a reflective surface and the reflected signal is recovered.

Abstract: An apparatus for tensioning a subsurface float line and the like during doyment of the line and thereafter includes a capstan rotatably mounted and located in a liquid medium, the capstan having a bore extending from one end of the capstan to the other end, the bore including a plurality of pump blades for moving the liquid through the bore when the capstan is rotated, the capstan also including turbine blades located around the circumference of the capstan and adjacent both ends of the capstan, the capstan also including a circular surface interposed between the turbine blades for communicating with the line to be tensioned. The pump and turbine blades do work when the capstan is rotated thereby creating a counter rotational (drag) force that tensions the line during and after deployment.

Abstract: A calibrated VHF/FM source for use in correcting tape recorder and receiver rrors which consolidates these functions in a lightweight rack using commercial test parts and maintains a high precision of accuracy by having the system monitor it's own output and correct the distortion and amplitude errors attributable to the nonlinear behavior of the a Voltage Variable Capacitance diode (VVC diode) of the Voltage Capactive Oscillator (VCO) of the VHF FM transmitter.

Abstract: A simple inexpensive gloss measurement device which makes use of the measment of a maximum angle of view of a clear reflection to obtain a measurement of gloss, consists of an instrument of L-shaped configuration with one or more small images (e.g., hollow squares) on the lower portion of the shorter arm and a graduated scale along edges of the longer arm. The device is placed on a coated surface to be measured, with the images close to the surface of the coating. The highest angle of view at which reflection of the images on the coating can be clearly recognized is noted on the graduated scale as a measure of the gloss of the coating.

Abstract: A significant increase in the structural strength of heated calcium alumie refractory products, such as mortar and concrete, can be obtained by the addition of alkaline earth borates, barium metaborate in particular, and heating in the range of 500 to 1000 degrees F. to cure the refractory, with an optimum strength provided at approximately 750 degrees F.

Abstract: Fiber optic sensors are used at one or more of the top pin and spring asslies in a pin tumbler lock to sense either authorized or unauthorized attempt to open the lock. A fiber optic switching element, in a simple capsule form, can be installed in new or existing locks. Fiber optic circuitry signals surreptitious attempts to open the lock.

Abstract: A thermal blast shield (64) is located on an aircraft (10) between two adent seats (20 and 22) to be stored in a housing (62) during normal aircraft operation. The thermal blast shield includes cables (84 and 86) passing through fairleads attached to the aircraft and then connected to the seats to pull the shield out of the housing and fully deploy it as the seat is ejected. A break-away mechanism (100, 102) causes the cables to break/separate after the thermal blast shield is fully deployed and jamming/locking mechanisms (104, 106) further control deployment of the thermal blast shield and preclude its post-deployment retraction. The thermal blast shield can be stowed window-shade like or accordianfold-like, and can be formed of a variety of flexible thermal resistant, blast resistant materials.

Abstract: An electrical transducer for indicating the position of an element movable n a predictable path, such as angular rotation, has no electrical parts on the movable element. A magnet mounted to the movable element traces a fixed path which lies adjacent to a stationary tubular enclosure containing liquid suspending a mass of ferromagnetic, electrically conductive material, the magnet drawing the mass of particles along within the tube on movement in its fixed path. Electrodes spaced on opposite sides of the tube wall along the length of the tube are electrically coupled by the mass of particles, whereby to indicate the position of the movable element.

Abstract: Warehouses, moving vans, buses, railroad cars, and cargo planes, adapted for storage or transport of cargo generally have tie-down studs or anchor bolts in their floors and walls. In order that cargo may slide across the floors or walls without interference the tie-down studs are mounted in recesses so that they do not extend beyond the floor or wall surface. These recessed studs have the disadvantage that objects to be attached thereto must be adapted to fit them. This invention provides an anchoring assembly which effectively converts the recessed anchor stud to an upwardly extending anchor bolt.

Abstract: Method and apparatus for applying a cooking mix to the rotary cooking drum of an automatic machine for making pancakes or the like by means of a continuously rotating paste-entraining roller partly immersed to a substantially constant depth in a mix tank, the film of mix being entrained by adhesion on the surface of the roller and contacting movable means for partly retaining this film, resulting in the formation of a bead of mix which touches lightly upon the surface of the cooking drum and thus coats it.

Abstract: A drop wire and/or cable clamp to provide a predetermined tension in a wire and/or cable between said clamp and a building to which said wire and/or cable is connected at one end and to produce a loose portion between said clamp and a box to which said wire and/or cable is connected at the other end. This clamp comprises a conical member, and a conical sleeve for mounting over the conical member. The clamp will be arranged for axially clamping the wire between the conical member and the conical sleeve and it will be possible to fix the conical member adjacent the box, with the conical sleeve mounted thereover and the wire therebetween. The net result will be to produce a loose portion in the wire or cable which has been installed between the box and the drop wire and/or cable clamp, and at the same time to obtain the portion under tension between the clamp on the building.

Abstract: The present invention relates to a self-induction device capable of steep saturation when the instantaneous value of a current flowing therethrough goes beyond a given level. The device comprises an annular magnetic core including at least one toroid coil of magnetic material, an insulating structure for supporting the coils and at least one insulated conductor coil embracing a section of said magnetic core. A tank encloses the core and the coils, the tank being provided with at least one input conduit for feeding a refrigerating fluid to the core and of at least one output conduit for the fluid. The insulated conductor coil is constituted of an insulated flexible cable wound around the insulating structure. The extremities of each conductor coil are so connected with the other conductor coils to effect a desired coupling, the so coupled coils being connected to an utility circuit.

Abstract: A tree processing apparatus and more particularly an apparatus for delimbing at least two, and preferably about ten, trees simultaneously. The trees, which have been previously felled, are each loaded, by one end in the apparatus and then all the trees are substantially simultaneously moved through the apparatus while being delimbed. Means can also be provided on the apparatus to saw the trees transversely into sections.

Abstract: A boat having a mainsail and a conventional rudder. The mainsail is supported by a mast and a pivotally mounted boom. A blade is pivotally mounted toward the free end of the boom about an axis that is substantially parallel to the mast. The blade acts as an auxiliary rudder for steering the boom and setting the angle of the sail. Though the boom pivots, the blade may be held parallel to a pre-set direction, so that the leeway component of the force of the wind on the sail is held substantially constant.

Abstract: A low viscosity, non-foaming stripping composition comprising by volume 79% -methylpyrrolidone, 20% monoethanolamine and 1% non-ionic surface active agent is applied at elevated temperatures (around 180 degrees F.) for removing thick (e.g., 10-mil) epoxy coatings and similar chemically resistant coatings from steel surfaces, and is suitable for spray application and for recycling.
