Abstract: QUARTZ CRYSTAL RESONATOR                  Abstract of the Disclosure A method and apparatus utilizing a quartz crystal resonator with an orientation substantially equal to (yxwl) 21.93°/33.93° vibrating simultaneously in two thickness modes to accurately measure temperature and unknown frequencies or to provide a stable frequency signal source.  By combining a quartz crystal resonator of the above type with either digital or analog compensation, the frequency-temperature deviation of one of the crystal mode frequencies is used as an internal thermometer and the second crystal mode frequency as a reference frequency signal.  The frequency signal for the thermometer function is utilized by the compensation network to correct the measurements made with, or to stabilize, the frequency of the reference frequency signal.  Additionally, the analog or digital compensation is accomplished by means of either a curve-fitting routine or an interpolation look-up table routine.

Abstract: ABSTRACT OF THE DISCLOSURE       An infrared heat-image camera is aimed at a hot surface not perpendicular thereto but instead in a direction almost parallel to the surface, presenting to the camera a heat image of the surface not cartesian but instead highly distorted in accordance with the laws of optical perspective.  The camera's output data is correspondingly non-cartesian and distorted with respect to organization and content, but the data is applied to a computer which transforms it to cartesian organization and cor-rects content, and then a corrected cartesian display is gener-ated, simulating the heat image which would be presented to a perpendicularly aimed camera.  Alternatively, the camera's scanning mechanisms are programmed to follow a non-cartesian scanning schedule, the geometry of which itself causes the camera output data to have the cartesian organization of a perpendicularly aimed camera.  Preferably, the scanning schedule is modified to effect transformation to cartesian organization in only one direction, and transformation to cartesian organization in the other direction is computer-performed.

Abstract: ABSTRACT OF THE DISCLOSURE:      A board brush apparatus for use on a self-propelling ice-resurfacing machine of the type having a frame supporting apparatus for shaving the surface of the ice and removing the shavings, and including a source of pressurized hydraulic fluid.  The apparatus includes a mounting bracket that is adapted to be attached to the frame on one side of the machine, and swingably connected to this frame is an arm having a motor-driven rotary brush at the outer end thereof.  The arm is swingable between a laterally extending operational position and a retracted position, and is moved from one position to the other by a hydraulic cylinder which is attached at one end to the bracket. The piston rod projecting from the other end of the cylinder is connected to the arm through an intermediate shock absorber. The motor driving the brush is a hydraulic motor, which is connected to the source of fluid pressure on the machine by a fluid line that is also connected to that end of the cylinder which, when pressurized, extends the cylinder to swing the arm out to operative position.  A control valve is connected into the fluid lines, and when the valve is turned to one position, the cylinder is extended and the motor is simultaneously started up.  Turning the valve to the other position causes the cylinder to retract and the brush motor to shut off.

Abstract: APPARATUS FOR FRICTIONALLY GRIPPING THE INTERIOR SURFACE OF A CONTAINER    DURING HANDLING BY AN ARTICLE      TRANSFERRING MEANS     Abstract of the Disclosure An apparatus employed with means for transferring articles, such as open mouth containers like glass jars, is actuable to frictionally grip the interior surface of a container during handling.  The apparatus includes a cup which forms a cylinder.  A post means is mounted in the cylinder and depends downwardly to a point outside the interior of the cup.  A piston is slidably mounted within the cup.  A flexible means, such as four circumferentially spaced straps, is secured at one end to the piston and at the other end to the post means at a point outside the cup.  A duct connects the cup to a controllable source of air pressure.  An urging means, such as a coil spring disposed between the post means and the piston, normally urges the piston to the top of the cup.  Upon application of air pressure to the cup, the piston is driven downwardly, and the straps flex radially outwardly so as to frictionally grip the interior surface of a container.  When air pressure is removed, the spring drives the piston upwardly, and the straps draw inwardly to release the container.  Preferably, the post means includes a threaded sleeve mounted to the cup and an adjustment screw-which threads into and out of the sleeve to set the initial flexure of the straps to accommodate containers with different mouth sizes.

Abstract: ABSTRACT OF THE DISCLOSURE:           Production process of lenses made of polymerizable synthetic resins.  According to the production process lenses made of synthetic resins may be obtained through casting of a catalized monomer which is polymerized up to the hardening point by warming it within a mold formed from two or more glass lenses, assembled together by means of a perimetrical gasket and a spring.  In the process the shrinkage of the polymer being formed is compensated through catalized monomer kept in presence of air outside of the mold, from where it may flow into the interior of the mold where is no air.  According to the process it is possible to obtain transparent and practically colourless lenses made from polymer, showing outstanding physico-chemical characteristics and possessing a diameter almost equal to that of the glass lenses forming the mold.

Abstract: ABSTRACT OF THE DISCLOSURE        An airport-surveillance system for determining the position and identification of aircraft (4) on the airfield which utilizes secondary radar and includes an interrogation station (1) installed on the airfield (3) and from which the interrogation signal is transmitted by way of a narrow sharply forcused beam of an antenna which scans the airfield and further includes transponding stations installed in the aircraft (4).          The present invention provides accurate identification and location of the aircraft by utilizing a receiver which has a sharply focused antenna beam and which is geographically located a distance away from the interrogation antenna and wherein the replies from the transponder of the aircraft are received by the receiving antenna only when the interrogation and receiving antenna beams (2, 22) intersect.  By scanning all locations of The airport, the position and identification of all aircraft on the airport can be determined. A modification of the invention provides that instead of or in addition to the receiving station having a narrow beam antenna a number of receivers (5, 6 and 7) having omni-directional receiving antennas can be mounted at different locations on the airfield for determining the aircraft positions by using hyperbola locating techniques. The airport surveillance system of the invention is particularly suitable for large airports.
