Abstract: ABSTRACT       An apparatus and method for automatically placing large plastic lids onto containers wherein the lids are dispensed individually from a magazine onto a slide with each lid being individually retained at the bottom of the slide for pickup by a container.  The lid is placed on the container by a pivoted roller and a different roller is used to level the lid after it is placed on the container.  The apparatus also contains means for removing the air from beneath the lid and has various sensing means to control the operation of the machine in proper sequence.  In the prior art, the automatic placement of lids is generally restricted to lids of less than about 8 inches in diameter, and when lids are placed on large receptacles, it is usually performed manually.   sd/?

Abstract: TITLE OF THE INVENTION:                METHOD OF PURIFYING REACTION PRODUCTS      ABSTRACT OF THE DISCLOSER;                A method of purifying reaction products that result from flame combustion of high-calorie fuels containing contaminants, such as sulfur-, chlorine-, and fluorine-compounds.  The purification includes the addition of additives in the combustion chamber for binding the contaminants.  The temperature necessary for binding the noxious materials is maintained by giving off a portion of the heat quantity released during the combustion of high-calorie fuels to the heat-absorbing material flow introduced directly into the combustion zone.  The mixing degree of the con-stituents of the reaction necessary for binding the noxious materials is obtained by adding the additives directly to the fuel and/or to the air for combustion.

Abstract: ABSTRACT      DISPENSING AND METERING DEVICES FOR LIQUIDS     A dispensing and metering device for liquids has a valve arrangement controlling the dispensing so that a metering chamber can be filled with a quantity of liquid and this quantity of liquid can then be drained.  To ensure suitable metering, parts of the valve arrangement may remain in suitable sockets at inlet and outlet ends of the chamber so that liquid cannot flow continuously from the inlet to the outlet, in use.  The outlet is provided below the chamber and an air bleed hole opens into the device between the chamber and outlet to allow air to enter the chamber to replace liquid being dispensed.  The bleed hole can be valveless.  In order to attach the device to a bottle, the device may have a resiliently deformable sleeve expansible radially into engagement with the interior of a bottle neck by axial compression of the sleeve.  The device thus fits many bottles.

Abstract: Automatic Lock-Positioning Of Foldable Helicopter Blades Abstract The foldable rotor blades (12) of a helicopter are automatically adjusted to pitch angles where they can be locked as a prerequisite to folding, by com-mands generated (98, 112) to cause trim actuators (39-41) to drive swash plate servos (17-19) to the correct positions, initially (98) in response to stored trim references (120) and eventually (112) in response to the difference (109) between stored swash plate servo positions (120) and current servo positions (20-22).  A claimed embodiment uses values of servo positions (20-22), just before unlocking the blades upon re-spreading them, to store, in nonvolatile memory (138), deviations (131) from nominal positions stored in read only memory, and generates (159) trim references in a subsequent folding operation in response to integrated values (166) to reduce actual position errors (162) toward zero from desired positions indicated by the stored deviations (148).

Abstract: Speed and Angle Timing Measurement Abstract of the Disclosure Apparatus for determining the speed of an engine and the phase shift between first and second shafts rotatably driven by the engine.  First and second fixed magnetic sensors generate first and second signals in response to movement of magnetically sensible members through circular paths at speeds proportional to the speeds of the first and second shafts, respectively.  Clock pulses from a fixed frequency clock are counted to obtain a first count between successive first signals and a second count between successive second and first signals.  The first count is inverted to obtain information as to the instantaneous engine speed.  The second count is divided by the first count to obtain information as to the instantaneous phase angle between the first and second shafts.  Successive instantaneous information is averaged to cancel the effects of engine torsionals. The present invention is particularly useful in engine control systems requiring rapid updating of information as to the speed and timing advance angle of the engine.

Abstract: ABSTRACT OF THE DISCLOSURE     An arc discharge lamp is provided using sealing compositions comprising mainly Al203 - SiO2 - MgO selected from compositions lying within the area ABCDEFG? on the undernoted ternary phase diagram and methods of using these are described.          Preferred compositions include between 15 to 28% by weight of MgO and 13 to 21% by weight of A1203 since these have lower melting points than others in the group.  The sealing compositions are used to seal end closure members of alumina or cermet to ceramic arc tubes for use in discharge lamps.  The compositions are selected to have linear expansion co-efficients compatible with the materials of the end closures and arc tubes.  The methods described give sealing times of between 3 and 4 minutes.

Abstract: ABSTRACT OF THE DISCLOSURE           Wire payoff devices are described which are used in conjunction with bobbin supporting cradles typically found in wire stranding and cabling machines such as high speed tubular stranders, bow or skip stranders and planetary stranders.  The payoff devices include dancer arrangements each having a pair of pulley wires mounted on a common support member which is itself mounted for independent movements along two substantially orthogonal directions.  One of the pulley wheels is effectively fixed and continuously releases the wire along the axis of the cradle.  The other or receiving pulley repeatedly traverses the axial width of the bobbin to follow the take-off points of the wire to provide uniform take-off and prevent scraping or chafing of the wire.  Movements of the receiving pulley towards and away from the bobbin as a function of the tension of the wire is translated, by means of pivoted lever arms, to a variable frictional force applied to the bobbin which substantially maintains the tension in the wire to a pre-established value.

An apparatus for inscribing and/or reproducing information in and/or from an optically inscribable and readable disk-shaped record carrier with a pre-formed track pattern, in which a first track modulation constituted by a radial wobble is formed, in order to obtain a tracking signal. A reference signal for deriving a tracking signal via synchronous detection is obtained by rectifying a difference signal which is the difference between the signals supplied by two photo-detector halves disposed on both sides of a dividing line which extends in the track direction, by subsequently extracting the component of twice the frequency via a phase-locked loop and by fre-quency-dividing said signal, so that phase shifts of 180° in said difference signal do not affect the synchronous detection.

ABSTRACT A new method and device has been developed to experimentally determine the state and amount of birefringence along any arbitrary direction through a birefringent body.   Such information can be used to determine the optical anisotropy of solid and liquid bodies, the residual and induced stress fields, etc.  Essentially, this method and device separates, from the light scattered in all directions along an arbitrary path of laser light in a body, three sheets of light which are subsequently collimated; each of these light sheets contains parallel light rays carrying information of interest.   The middle light sheet indicates the line of measurements, which is identical with the path or position of laser beam in a body.  The two outer light sheets carry two complementary and independent  pieces  of  information on the  state and amount of birefringence along the line of measurements.   Thus, both outer sheets of light can be used simultaneously to increase the reliability and accuracy of the birefringence measurements.     8 claims. 5 drawings (figures).
