Abstract: ABSTRACT OF THE DISCLOSURE     Ultrasonic apparatus and methods of opera-tion thereof for measuring and remotely displaying the amounts of fuel and water in a tank, includes an ultrasonic transducer at a fixed distance above the bottom of the tank, a plurality of submerged reflec-tors vertically arranged at fixed distances above the transducer and a remote console, containing a com-puter, for activating the transducer and receiving signals of ultrasonic reflections developed by the transducer. The reflectors are thin, planar sheets increasing in horizontal length with increasing dis-tance from the transducer, the lower edges of which may be concave to maximize the reflections of ultra-sonic pulses from the transducer back through the fluid to the transducer.

Abstract: L'invention concerne une soupape rotative pour un moteur à combustion interne comportant au moins un cylindre définissant une chambre de combustion et pourvu d'une tête munie d'orifices d'admission et d'échappement. La soupape rotative selon l'invention est caractérisée en ce qu'elle comprend un corps cylindrique creux permettant le passage intérieur de matières gazeuses et comportant sur sa périphérie externe une bague conique définissant une surface angulaire destinée à s'appuyer de façon étanche contre un siège de soupape correspondant formé dans un carter de soupape du moteur. Cette bague est pourvue d'une canalisation communiquant avec l'intérieur du corps cylindrique et faisant orifice sur la surface angulaire de façon à coïncider lors du mouvement rotatoire de la soupape avec l'un des orifices d'admission et d'échappement s'étendant au travers du siège de soupape et permettre ainsi le passage des matières gazeuses entre l'intérieur du corps cylindrique et la chambre de combustion du cylindre. Des moyens d'accouplement sont prévus pour joindre la soupape à une soupape similaire adjacente alignée axialement de façon à transmettre le mouvement de rotation d'une soupape à l'autre tout en permettant un déplacement longitudinal des soupapes l'une par rapport à l'autre. L'invention permet de pallier aux problèmes de dilatations thermiques reliés aux moteurs à soupapes rotatives.

Each of the arms has a hole at the outer end for cooperation with a shaft for anchoring the arm to the ground.  Each of the shafts is threaded and has a plate at the bottom end and two nuts at the top end for adjustably clamping the arm at a required height.  In assembly, three holes are drilled in the ground to a depth of three feet and a diameter of six inches, following which the plates are positioned at the bottom of the hole with the shaft extending centrally of the hole to a position above the ground.  The holes are then filled with concrete and before setting the rigid frame is attached to the shafts and adjusted to the required vertical position by screwing of the nuts on the shafts.

Abstract: Abstract A method for contour recognition of completely or partly transparent objects (2), e.g. containers like glass or plastic bottles, said object being advanced through an illumination and detector station (3-13; 3, 4, 20, 21) and there being illuminated on at least part of its circumference.          The light reflected by said object (2) is viewed by a detector (4,3) against a background that is dark relative to said object, and the viewed image is recorded and converted to pulse signals that are processed to yield a numerical code characteristic of the object. During recording distinct signals are generated which are characteristic of the width (bn) of the object relative its corresponding height (hn) for a number of levels (n). The signals are then processed in a threshold circuit (24) and a pulse generating circuit (25) for the generation of said pulse signals (P), for each height (hn) two pulses (22', 23') being formed, the distance between the leading edge of the first pulse (22'9 and the trailing edge of the second pulse (23') defining the width (bn) of the object at said height (hn). Said distinctive signals are preferably generated by a TV camera, e.g. a CCD camera.          Utilization especially in connection with contour recognition of return bottles.     Figures 4 and 6.

Abstract: VIDEO WAVE CODEC            Abstract An analog-to-digital converter circuit is disclosed employing a plurality of comparators each having the same reference voltage input.  At each comparator stage plus and minus binary "bit weights" are developed. Selection of either the positive or negative bit weights at a stage allows a binary fraction to be added or subtracted. The number of comparator stages need only equal the number of desired digit positions in the output instead of having one comparator for each quantizing level.  The comparator stages operate in a "wave" or "pipeline" manner under the control of a plurality of high speed wave forms so that each stage decodes its respective binary digit for one analog sample while the other stages are decoding their respective binary digits of other analog samples.

This device includes a pair of opposed, elongated recesses, each being disposed within one of the side surfaces, extending along a major portion of the lure between a dorsal portion and a ventral portion thereof.  The fishing lure provides emanation of a predetermined fish-attracting wake pattern as an auditory stimulus, as well as visual stimulus attractive to fish from its highly reflective outer surface which is adapted to receive both substantially reflective and non-reflective markings.  The predetermined fish-attracting wake pattern is produced by a flange associated with each of the elongated recesses, as the lure is drawn or trolled through a body of water.

Abstract: ABSTRACT         Transparent films of silicon dioxide are produced on a substrate by sputtering silicon toward the substrate from a silicon target.  The target is clamped to the remainder of the cathode along substantially the entire length of its edges, by a clamp set of at least one clamp.  Each clamp has an outer surface extending upwardly away from the target surface to a position thereabove.  The target is furthermore covered by a baffle disposed between the entire target and the substrate.  Oxygen is admitted between the substrate and baffle at a rate to oxidize silicon sputtering toward the substrate, while not oxidizing the target.  An rf discharge is applied to the substrate at a power density substantially .08 to .16 watts cm-2.  The substrate is dimensioned relative to the cathode, and spaced therefrom, so that the foregoing rf discharge at the substrate electrode, generates a self-bias voltage thereon, of between substantially -70 to -100 volts.  The total open area of the baffle used in the foregoing method, is preferably less than 50% of the target surface.

Abstract: Abstract of the Disclosure A scanning keratometer for the rapid and accurate measurement and mapping of the corneal curvature is disclosed.         The keratometer has a monochromatic light source directing light to a scanner, preferably controlled by a microcomputer.  The scanner directs the light to a holographic element functioning as a lens which in turn focuses the light to a fixed focal point forward of the holographic element independent of the area of the holographic element being illuminated.  The subject's eye is position with respect to the fixed focal point so that a part of the light incident to the eye is reflected from the surface thereof again passing through the holographic element, to be deflected from the main optical axis of the system to a suitable area sensor. Assuming the subject's eye is properly positioned and the cornea surface matches the shape of an ideal cornea, the light incident to the cornea will be reflected in the same direction as the incident light, ultimately impinging on the center of the sensor.  If, on the other hand, the local area of the cornea being illuminated is not matching, the light reflected from the cornea will be at an angle with respect to the incident light, ultimately impinging on the sensor at a position dependent upon the shape of the local area of the cornea then being illuminated.  Various methods of eye positioning, scanning and other aspect  of the system are disclosed.

In a further preferred embodiment, a rotary motor (M) with an eccentric weight (W) is briefly energized to vibrationally clear any accumulation of droplets from the chamber wall.  Other embodiments utilize a plurality of mirror elements (8a, 8b, and 8c) to define an optical path from the source (6) to the detector (7) which traverses three or more times the region through which a drop falls.
