Abstract: In a grain elevator, grain mixed with dust is delivered near the top of a grain silo to the receiving orifice of a grain chute. The chute includes an enclosed conduit which extends from the top of the grain silo to its floor and deposits the grain in the silo without freely falling in the interior of the silo. The conduit has a tandem column series of vertically extending doors which are counter-balanced to be normally closed and which are opened by the weight of the grain in the conduit. The fall of the grain within the conduit separates the grain from the dust and the dust is removed by an exhaust fan connected to the conduit, the air flow being through the open bottom doors of the conduit, through the conduit, and out of the silo to a tube connected to a dust separator. In addition, the grain falls within the conduit and flows out of the doors which the grain column opens and which are immediately above the level of the grain already delivered into the silo, the other doors remaining closed.

The plug has a tubular shank portion which extends from the top closure wall portion and whose outer face retains the plug in the hole. The shank's outer face has a first circumferential band canted inwardly and a second circumferential band joined thereto which is canted outwardly. At least one, and preferably two, side flats are formed on the shank portion, which flats flex inward when the plug is inserted into the hole.

Abstract: A plastic cap has a tearable outer skirt depending from a top disc, the interior of the skirt having means engaging with cooperating means on a container neck to hold the cap in place until the lower portion of the skirt is torn. To prevent dishonest persons from defeating the tamper resistant character of the cap by prying upward on the bottom edge of the cap skirt, a shoulder has been formed on the neck fitting closely under the bottom edge of the cap skirt. To further reduce such prying, a series of protrusions is formed on the shoulder with spaces between the protrusions. The protrusions inhibit fingernails from access to the lower edge of the skirt. The bumper ring which cooperates with loading grippers is interrupted by straight sections which prevent collapse of the bumper ring when the cap is applied.

Abstract: During open-heart surgery an EEG (electroencephalograph) system detects a patient's brain waves, amplifies the brain wave signals and converts them into digital data. The cardiopulmonary bypass pump (heart-lung machine) is connected to blood flow and blood temperature transducers whose measurements, in digital form, are used to calculate a standard of normal electro-physiological responses to blood flow and temperature changes with which the patient's actual brain wave responses will be compared. A visual display indicates to the surgical team, as to each of eight brain sectors, whether the patient's brain waves show that remedial action may be required. The digitalized brain wave signals, after processing to reduce muscle artifact and other noise, are displayed, in one embodiment, as intensity modulated time segments, using a moving window type of display in which the current segment is statistically compared to the group of immediate prior segments to provide a current self-norm (NORMS n).

Abstract: Disclosed are a method and an apparatus for monitoring the brain state of a patient during a medical procedure relative to a self-norm established at an earlier time, when the patient is in a state selected for medical relevance to the planned procedure. To establish the pre-procedure self-norm, electrical measurements are taken of brain functions which are selected for medical relevance to the procedure, and are processed to produce, for each brain function of interest, a respective statistically and medically significant mean and variance. During the procedure, the same brain functions are electrically measured at each of a sequence of time intervals selected for medical relevance to the procedure.

Abstract: A tertiary olefin is produced by contacting a gaseous tertiary ether usually represented by the following general formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are alkyl groups each having 1-4 carbon atoms which may be same or different and R.sup.4 is an alkyl group having 1-3 carbon atoms, with a catalyst obtained by calcining a silica-alumina compound at 700.degree.-1100.degree. C. in order to effect cracking of the tertiary ether. This reaction may be carried out in the presence of steam to result in further improvements.

Abstract: A fastener to removably secure two panels consists of a spring-loaded toggle latch (catch unit) on one panel and a keeper plate (strike) with a keeper lip on the other panel. The toggle latch comprises a pivot bracket with a flat base plate and opposite upstanding side ears, a pivotable operating lever (handle) and a pivotable hasp member (draw bar) having a downwardly turned lip at its free end to engage the keeper lip. The three members of the toggle latch are solely joined by left and right single-turn coiled torsion springs which spring-load the hasp member. In one embodiment the flat base plate of the pivot bracket has two openings, each with a series of staggered indentations forming pairs of indentations, which indented pairs are differently spaced from the edge of its panel, to permit adjustable mounting of the pivot bracket on its panel.

Abstract: A method of applying fluid paint utilizes a marking device having a fluid paint-filled reservoir, a tip comprising a spring-loaded ball and its spring, and pressure means, such as collapsible walls or a pressure device, to apply pressure to the fluid. The paint, applied to a fabric as a decoration, is an oil-in-water emulsion in which oil mixture droplets (globules) are evenly dispersed in the water phase. The oil droplets are composed of an oil mixture preferably based on an oil-modified polyurethane or oil-modified alkyd or other oil-modified resin and drying agents. The oil-in-water emulsion contains a surfactant, a gellant, and an anti-foam agent. The pigment dispersion may be in the oil droplets or in the water phase.

Abstract: An ink jet printing method by means of an electrostatic type ink jet printing apparatus, in which charging stages forming one scanning line on a recording sheet paper are divided into groups, ink droplets for printing each group being so charged that they impinge on the scanning line at intervals of a predetermined number of stages, the groups having starting stages different from each other, which results in that the influence of the aerodynamic resistance due to the preceding ink droplets on the ink droplet concerned and that of the Coulomb's force due to the preceding and neighboring ink droplets on the ink droplet concerned are suppressed to the minimum and, consequently, the quality of printing is considerably improved.

Abstract: A coil winding machine winds a wire about a core to form, for example, one-half of a television deflection coil. The wire is spun about the core by a flyer arm which is rotated about an axis and guides the wire over a series of pulleys rotatably mounted thereon. The wire is pulled through the bore of a tubular shaft, which carries the flyer arm, which shaft is driven rotatably and reciprocally along its axis. The core is removably held in a clamp which is fixed to a tool holder having gear teeth, preferably a sector of a worm gear. The tool holder is driven to obtain a rocking motion during the winding operation by a worm mounted on a drive shaft. That drive shaft is rotatably held in the cross-member of a cradle assembly which cradle assembly is pivotally mounted on the base and rocked back and forth during the winding operation.

Abstract: An internally powered pump is surgically implanted to eject liquid under control of the experimenter. The pump reservoir is flexible and contains the liquid to be ejected. The reservoir is collapsed by a piston which is pushed by a compressed spring. The spring is released, step-by-step, by a pawl and ratchet mechanism. The pawl is magnetically responsive and pivots when a magnetic field is applied to the pump.

Abstract: A paper loading apparatus includes a paper retaining roller and a stop claw, both arranged for movement toward or away from a platen in opposite directions from each other. When the stop claw bears against the platen, paper is inserted into the apparatus and is properly held by the claw. Subsequently, the paper retaining roller is brought into abutment against the platen, whereupon the stop claw is moved away from the platen. The movement of the roller and the stop claw toward or away from the platen occurs automatically in response to a detection signal which indicates the insertion of the paper into the apparatus. In one embodiment, the platen is peripherally formed with a plurality of axially spaced annular grooves which extend in a direction perpendicular to the axis thereof, and receive protuberances formed on the free end of the stop claw.

Abstract: In a shutter-priority automatic single lens reflex camera the operator views the scene through an eyepiece viewfinder whose optical path is through a variable iris diaphragm and a taking lens. When a depth of field preview button is pushed by the operator, the diaphragm closes down to the aperture (opening) determined to be correct for the selected speed under the ambient light conditions. A system is provided to aid the operator in envisioning a black-and-white picture of a color scene by presenting a partially color deleted view of the scene to the eyepiece viewfinder. The operator pushes a button which pulls a special color filter into the optical path of the viewfinder and simultaneously sends a control signal to the camera central processing unit (CPU). The CPU, upon receiving the control signal, determines the proper diaphragm opening for the scene, compensates for the filter (by stopping up) and permits operation of the diaphragm to close down to the compensated aperture.

Abstract: A system for the non-invasive inspection of a living organism utilizes two ultrasonic fields, one of which is produced by a perturbing beam transmitting transducer to perturb an internal region of tissue at a focal region which may be subject to movement. The second ultrasonic field consists of a set of ultrasonic beams, constituting a sense beam and reference beams, and which may be portions of a single beam or a plurality of separate beams and which are directed through and near the focal region of the perturbing field before and/or after perturbation. The time of flight differences of the sense beam and reference beams are detected by a plurality, preferably at least three, receiving transducers whose outputs are processed by a digital computer system, interacting with the signal analysis electronics, to derive information concerning the internal tissue of the living organism.

Abstract: A direction detection apparatus comprising a magnetic sensor which senses a geomagnetic azimuth, a turning-angle sensor which senses a turning angle dynamically, a magnetic-disturbance detector which detects a magnetic disturbance on the basis of the output of the magnetic sensor, and a signal switching device which transmits either the magnetic sensor output or the turning-angle sensor output to a display device in accordance with a signal from the magnetic-disturbance detector. The traveling direction of a moving object can be detected as a precise geographic azimuth even when the moving object lies in a place subject to the magnetic disturbance.
