Abstract: The shaft of a wind driven propeller is coupled to the rotor shaft of an electrical generator through an over-running centrifugal clutch and a speed changer mechanism. When the wind attains a certain velocity, a propeller shaft speed responsive device closes a switch that connects the output terminals of the generator to an energized electric distribution system so the generator runs as a motor long enough to accelerate up to rated speed and concurrently get the speed changer mechanism up to speed. The clutch engages the propeller shaft to the speed changers at this time and the generator begins to supply supplemental power to the system. Because all rotating parts are brought up to matching speeds together, the inertia shock that would result from connecting the propeller to a speed changer and generator that are at a standstill is avoided. When wind velocity drops, the generator runs as a motor for a moment and causes the over-running clutch to disengage.

Abstract: An effluent precipitation and neutralization chamber is useful for treating x-ray photographic chemicals prior to discharging them into a drain. Desilvered photographic fixer is mixed with spent developer within the chamber. The resulting iron precipitates settle to the bottom of the chamber or adhere to ribbon-like flow restrictors within the chamber. Relatively clear fluid of approximately neutral pH concentration is discharged to the drain. The chamber is openable for removing and properly disposing of the iron precipitates.

Abstract: A locking mechanism for a mobile storage system comprises a reciprocable lock bar selectively engageable with a rack fastened to a system track. The lock bar is moved into and out of engagement with the rack by a push-pull cable actuated by a conventional key and lock device. The lock bar is urged into engagement with the rack by a spring. Each rack tooth is formed with a vertical and a sloping surface, and the lock bar has cooperating surfaces. When the mobile storage unit is moved in one direction the lock bar ratchets over the teeth sloping surfaces against the spring bias, but movement is prevented in the opposite direction because the spring urges the lock bar vertical surface into cooperating engagement with a rack tooth vertical surface.

Abstract: An open end ratchet socket wrench has sockets with a slot in the side wall. Teeth on the circumference of the socket engage and cooperate with pawls on the wrench head.

Abstract: X-ray energy-difference images are obtained simultaneously by exposing a body to a broad energy spectrum x-ray beam while a radiographic film package is disposed between front and rear x-ray intensifying screens. The film package has two superimposed films with a light-opaque sheet between them. The front screen, on which the polyenergetic image beam emerging from the body is incident, is excited to luminescence by x-ray photons predominantly in one energy band and the rear screen is excited predominantly by photons in another band. The light opaque sheet preferably contains x-ray filter material for additional filtering of photons to increase the fraction of photons at said other band to which the rear screen is sensitive. A shadowgraph of a marker is formed on the film emulsions during x-ray exposure to aid in matching congruent picture elements on each film when the developed films are being read out to obtain signals corresponding to their intensities.

Abstract: Medical diagnostic X-ray table assembly including an X-ray source and detector. The entire assembly is mounted on a cantilevered horizontal transverse pivot for being raised and lowered or tilted as a unit. The table assembly is mounted eccentrically to the horizontal transverse pivot so the table can clear the floor when tilted to the foot down position, yet the table is low enough to be mounted easily by a patient.The X-ray source and detector means are each supported by a series of superposed carriages driven by lead screw drives, thereby allowing the source and detector to independently translate transversely, longitudinally, and toward or away from the patient support. The X-ray source is also mounted on a transverse axis for being pivoted. A novel hydraulic mechanism is provided for tilting the table.

Abstract: A load-bearing bar (1) for office furniture, the bar having a modular structure and being defined by a number of interconnected modules each consisting in a bar segment (18) having a substantially U-shaped cross-section. Each bar segment (18) is formed by two lateral beams (2) rigidly connected to each other by an intermediate base element (3) which supports a channel-defining member (59) for telephonic and electric wiring.

Abstract: A folding table assembly includes enclosed gaseous power cylinders for assisting the folding and unfolding operations. The cylinders are mounted to the supporting legs so that their weights are not added to that of the table members to be lifted. The cylinders exert constant forces tending to fold the table, and they provide cushions to resist the table weight during the unfolding operation.

Abstract: A vacuum cleaner head with a hood which closely fits the floor has a rotor with a plurality of nozzles supported on a hub with a slot. Outside air is drawn through the hub and nozzles into the hood to provide air jets from the nozzles which assist in disloging particles for recovery by the vacuum.

Abstract: A container labeling machine for applying one or the other of normal length body labels or extra-length boy labels has a rotating rotary table with container supporting controllable rotary plates. Adjacent its periphery is arranged a first labeling station for applying the normal length labels with a rotating labeling cylinder and a second labeling station for the extra-length labels with a stationary label container contacting the path of rotation of the containers. Two independent drives are provided for rotating the plates, one of which regulates the positioning and/or rotation of the rotary plates in the area of the first labeling station, and the second for continuous rotation of the rotary plates in the area of the second labeling station. The rotary plates are selectively connectible with the first or second drive. The two labeling stations and their common brush-on station overlap one another, whereby a very short total treatment stretch is possible.

Abstract: Digital values representing trial bias voltages that are to be applied to the control grid of an x-ray tube are stored at respective locations in a battery energized RAM. The addresses of the locations correspond to the nominal x-ray tube currents that relate to the bias voltages. A model of the actual bias voltages for selected tube currents is made and supplants the trial voltages. A trial digital bias value is converted to an analog signal used to control the output level of a generator that applies the bias voltage to the grid. An x-ray exposure is made. The x-ray dosage in terms of actual milliampere-seconds (mAS) is measured and compared with a reference desired mAS value. A computer calculates to a first approximation the bias voltage that should have been applied to obtain the desired mAS and returns the new digital bias voltage value to the same location.

Abstract: An ink agitator element is mounted to a carriage and translated reciprocally lengthwise of a roller in the ink fountain. The carriage is driven by means of a cable connected to the piston of a pneumatic actuating cylinder. A 2-way control valve alternately pressurizes and exhausts opposite sides of the piston. Adjustable stop members set anywhere along the carriage path determine carriage travel distance in both directions by operating the valve to effect carriage reversal. Various ink agitating or stirring elements are disclosed. One such agitator element caused to swing at the end of its travel to thereby sweep ink toward the ends of the fountain roller besides urging ink into the roller nip as the agitator element translates.

Abstract: In the containing filling device the tank for the liquid to be dispensed into containers has gas somewhat over atmospheric pressure applied to the liquids surface. Each filling station has an outlet leading to the container being filled, a gas valve coupling the tank to the container and a fluid valve coupling the tank to the conveyor. The liquid above the tip of the tube that leads from the gas valve is forced back into the tank by means of gas pressure injected into the outlet after the filling operation is ended. In which case the fluid valve is forced closed and the gas valve is forced open. Because of the forced open gas valve the injection of gas takes place at very low pressure differential, causing neither disturbance of the liquid in the container and in the tank nor blow out of liquid below the level of the tank of the gas return tube.

Abstract: An X-ray tube is movable between a minimum distance from an image receptor and a maximum distance. Signals are generated representative of the X-ray tube focal spot-to-image distance (SID), the peak kilovoltage (kVp) that is to be applied to the X-ray tube anode during a fluorographic exposure and the desired brightness of the X-ray image. The signals are processed in a manner that results in a control signal being developed that adjusts the X-ray tube filament current in a way that produces an X-ray tube current (mA) during the exposure which results in a constant limited X-ray dose rate at the X-ray beam entrance plane of a patient at any permissible kVp and SID setting and assures that the dose rate limit will not be exceeded at minimum permissible SID regardless of the selected kVp.

Abstract: An oxygen probe for measuring the characteristics of furnace gases. The probe includes electrodes of a long lasting and relatively inexpensive nickel containing alloy. The probe is formed with apertures and internal passages for ventilating the three phase contact zones between gas, electrolyte, and electrodes with furnace gases, thereby minimizing errors due to catalytic reactions at the electrodes. The probe sheath may be composed of the same alloy as the electrodes, and the electrodes may be fabricated as an integral part of the sheath, so that the sheath serves both as a structural member and as an electrical conductor for conducting voltage generated within the electrodes. A gas pump may be used to assure adequate ventilation to the electrode-electrolyte interfaces.

Abstract: A device for displaying the names of items and their prices uses a generally planar panel that has pairs of parallel tracks on its rear side and parallel guide channels on its front side. There is an elongated aperture in the panel between each pair of tracks and guide channels. Strips bearing printed item names and other information are inserted in the channels. The strips have variable numbers of either apertured or transparent windows aligned with the aperture. A tape carrier for tapes bearing indicia such as numerals for composing prices that are displayed through the windows is engageable with the rear tracks by means of its inherent flexure property. Divider members engage the carrier with a snap action and they create channels in conjunction with the carrier surface for guiding and restraining the edges of the tapes against all but longitudinal movements.

Abstract: A blade for cutting and stripping insulation from insulated electrical conductors has two blade angles leading to the cutting edge. The first angle is a gathering angle which opens onto the leading surface of the blade and provides a wide opening for gathering offset insulated conductors. The gathering angle converges toward the interior of the blade and intersects the second blade angle, which also converges toward the blade interior. The second blade angle, the cutting angle, terminates in a radius cutting edge adapted to slice the insulation. The blade walls defining the cutting angle are tangent to the cutting edge radius. The cutting angle is minimized so that the radius cutting edge provides a maximum circumferential contact with the conductor. The blade may include a stop for positively controlling the cutting stroke to avoid nicking the conductor.

Abstract: The isocenters of two independent frontal and lateral viewing X-ray systems are made coincident using an X-ray permeable target frame that has congruent crosshairs defined by X-ray impermeable lines on opposite side walls. A small steel ball is located in the frame between side walls on a line running from the intersection of one set of crosshairs to the other. A television display of the X-ray image of the ball resting on the patient supporting table top with the frame leveled and of the crosshairs with the frontal system having the central ray of its X-ray beam vertical and then horizontal and with X-ray impermeable crosshairs on the image receptor permits shifting the frame until the crosshairs on it and on the receptor are coincident with the ball and the isocenter in vertical and horizontal orientations. The procedure for establishing the isocenter of the lateral system is comparable.

Abstract: A diaper fastener strip has a first zone coated with a release material and a coat of adhesive over the release material and a second zone coated only with adhesive. The part of the strip having the second solely adhesive coated zone is adhered tenaciously to the margin of the fluid impermeable outer backing sheet of a diaper. The part of the strip having the first release material plus adhesive coated zone is folded over the diaper margin to contact the adhesive with the margin of the inner fluid permeable sheet of the diaper. When the strip is unfolded the adhesive transfers from the release material in the first zone to said inner sheet margin and becomes exposed for securing the diaper on a body. An alternative strip has said adhesive coated second zone adhered to the backing sheet and two consecutive zones next to it.

Abstract: For cleaning container filling machines through utilization of cleaning-in-place (C.I.P.) canisters that are inserted between rotating filling valves and their matching lift cylinders, the lift cylinders are arrested in their lowest end position by the C.I.P. canisters acting as spacers to allow the cam follower rollers to pass under the stationary lifting cam at a slight distance, while the C.I.P. canisters are held against the filling valve under pressure. The C.I.P. canisters thus remain pressed against the filling valves during the full rotation of the filling machine without the follower rollers being acted on by the lift cam.
