Abstract: A rotating electric machine with a permanent magnet rotor, provided with a stator composed of a winding and a ferrite structure to provide low power losses and improved efficiency particularly at high rotor revolution rates, is constructed so as to optimize the performance of the permanent magnets on the rotor. In the preferred embodiment of the invention, the ferrite being selected for its low hysteresis and eddy current power losses, generically referred to as core loss and its low loss factor which are frequency dependent, replaces laminated electrical iron. Additionally the permanent magnets selected to exhibit high intrinsic magnetic intensity and low remanent magnetic flux density, are arranged in conjunction with the ferrite to maximize the magnet's energy product as well as the magnetic circuit gap length, which in combination provides a radical improvement in machine energy density.

Abstract: A long-lasting water-based paint having an exceptional resistance to both chemical and mechanical damage comprises a combination of acrylic resins as pigment binders. Flaked highly corrosion-resistant stainless steel, finely ground mica flakes, calcium carbonate and a small amount of zinc oxide are included in the pigment. The paint is prepared by adding at least approximately 60% of the acrylic resin into the paint after all of the pigment, substantially reducing the amount of air entrapped in the paint during mixing.

Abstract: A process is disclosed for the recovery and reuse of the heat contained in the gas/vapor overhead mixture from a stripping column in which a noncondensable gas is stripped from a liquid solution by contacting the solution with a hot vapor such as steam. The steam or other vapor in the overhead mixture is separated from the non-condensable gas or gases by preferentially passing the vapor through a semipermeable membrane. The water or other condensable vapor is then compressed and either reinjected at the bottom of the stripping column or condensed in the column reboiler, thus permitting its reuse in the stripping process. If the compressed vapor is reinjected into the stripping column, it serves as the stripping medium itself. If the compessed vapor is condensed in the column reboiler, its latent heat of vaporization is thereby recovered and used to generate the required stripping vapor by boiling the solution being stripped.

Abstract: A fuel-saving energy storage vehicle drive system which saves fuel, primarily under stop-and-go driving conditions, by collecting, storing and using energy normally lost in the braking or deceleration of the vehicle, by automatically controlled operation of the engine under certain conditions, and by automatically controlled use of the stored energy and engine respectively as alternative or supplemental prime movers for each other for driving the vehicle. Subsystems for preventing waste of deceleration energy and stored energy are provided, and compact transmission layout and packaging are provided which facilitate installation of the new system in existing vehicles.

Abstract: A loader permitting a boat to be conveniently lifted from an upright position alongside a vehicle to an inverted position atop the vehicle includes a pair of tracks extending transversely across the top of the vehicle and downwardly along the side of the vehicle, and a carriage mounted for travel along the tracks between a raised transport position and a lowered loading and unloading position. A cable is connected with a winch and extends around a pair of sheaves located on opposite sides of the carriage to extend from the winch to a lower or far side sheave, then to an upper or near side sheave, and then to the boat. In loading a boat, retracting the cable first tilts the boat sideways into contact with the carriage and then raises both the carriage and the boat to the transport position. The apparatus permits a boat to be loaded onto or unloaded from the top of a vehicle used to tow another vehicle such as a camping trailer without the need to first unhitch the trailer.

Abstract: A method for filtering and discharging waste water from a septic tank in predetermined increments and preventing passage of suspended solids from the tank while resisting blockage of the fluid discharge apparatus by such solids. A removable fluid discharge device, such as a submersible pump or dosing siphon with a trigger trap, is enclosed within an encircling filter element which is similarly encircled by a protective housing, and the entire assembly is located within a septic tank immersed in waste water. The protective housing is impervious to the passage of waste water into its interior except through apertures located in the vertical sidewalls so situated as to allow water from only the clearest layer within the tank to enter into the housing and contact the filter. Functionally, the housing protects the filter from blockage by the high concentration of solids present in the layers above and below the clearest layer.

Abstract: A lift truck rotatable paper roll handling clamp of the pivoted arm type for clamping paper rolls of varying diameters and shifting the position of the roll relative to the lift truck between a position of unequal extension, wherein the forward end of one clamp arm extends a greater distance forwardly than the forward end of the other clamp arm, and a position of equal extension wherein the forward ends of the clamp arms extend a substantially equal distance forwardly of the lift truck. The clamp has a rotatable frame upon which a subframe is mounted by a first pivotal connection for selective tilting of the subframe relative to the rotatable frame. Mounted upon the subframe are a pair of clamp arms, each being pivotally connected to the subframe at spaced pivotal connections located on either side of the first pivotal connection. One clamp arm is longer than the other, and pivots with respect to the subframe through a greater maximum angle than does the other arm.

Abstract: A lift truck load clamp, for handling cylindrical loads such as paper rolls, having an automatically adjustable load positioner extending between the clamp arms which moves forwardly in response to closure of the clamp arms and rearwardly in response to opening thereof to assist the lift truck operator in positioning the clamp arms with respect to rolls of different diameters such that the contact pads of the clamp arms automatically grip such differently-sized rolls in diametrically-opposed relation. The load positioner is particularly adapted for use with clamps wherein both clamp arms are movable with respect to a clamp frame, because each end of the positioner is separately movable forwardly or rearwardly with respect to the frame in response to movement of the respective adjacent clamp arm.

Abstract: A method and apparatus for analyzing cardiac electrical activity and other life signs, and triggering a therapeutic current. A signal representative of cardiac electrical activity is analyzed by two distinct analog circuits and a logic protocol is provided to indentify cardiac arrhythmia based on the outputs of the circuits and the presence or absence of respiration. One circuit employs comparison of the electrical signal with a previous peak value thereof, and is characterized by its tendency to double-count some QRS complexes. The other circuit compares the sum of the rectified and low-pass filtered signal plus the derivative of the signal to a reference level, and compares the rectified and filtered signal to a threshold level, to identify QRS complexes while largely ignoring ventricular fibrillation.

Abstract: A magazine latch release mechanism for repeating rifles and the like having a magazine catch carried on an axially movable shaft extending laterally through the receiver of such a weapon is operable by a lever extending downward proximate the rear side of a removable magazine to permit release and removal of the magazine with one hand while the other hand continues to grip the weapon. A sleeve surrounds a portion of the laterally extending shaft within the receiver, part of the sleeve extending outwardly through a receiver wall. The sleeve is pinned to the shaft outside the receiver wall. An end of the latch release lever is pivotably connected to the sleeve within the receiver and the opposite end of the lever extends downwardly from the bottom of the receiver.

The conveyor is foldable, including a horizontal folding axis located at the top of the conveyor, an "A" frame located intermediate relatively folding portions of the conveyor, and an extensible motor whose ends are attached respectively to one of said relatively foldable conveyor portions and to said intermediate "A" frame, said motor being located medially between lateral sides of each of said portions of said conveyor.

Abstract: An apparatus for placing film in the proper position for taking an x-ray or similar image of a patient lying on a bed having a compressible mattress is comprised of a base which supports the apparatus and is arranged for fitting between the bed and the mattress. A film holder, which is arranged for removably receiving and carrying a film cassette is adjustably positioned above the mattress adjacent to the patient by a positioning apparatus which is interconnected to both the base and the film holder. A locking device associated with the positioning apparatus locks the film holder relative to the base when it is in its desired location. Accordingly, the film holder support apparatus can be used to compress the mattress alongside of the patient thereby permitting the film to be placed in a location adjacent to the patient which would otherwise be occupied by the mattress.

Abstract: A hydraulic positioning system for precisely and rapidly positioning objects of the type likely to impose impact loadings on the system. The system is particularly adaptable for use in sawmill setworks for precisely positioning logs preparatory to sawing thereof. High impact loads are compensated for by special rapid-acting shock-absorbing hydraulic relief circuitry responsive to differences between impact overpressure and system pressure.

Abstract: A fairing for mounting atop the cab of a motor vehicle such as a tractor unit of a tractor-trailer truck includes feet for supporting an aerodynamically-shaped, thin-walled hollow front member and a rear panel which substantially closes the rear side of the fairing to reduce the lifting effects of turbulent air flow. The fairing includes feet and legs which support the fairing spaced above the vehicle cab to provide visibility for cab top-mounted clearance lights. The fairing may be manufactured of fiberglass reinforced resin sheet material, with the rear panel providing sufficient support for the front member despite hollow thin-walled construction.

Abstract: A housing for an electrical circuit component such as a magnetic contact reed switch for use in a security system.

Clamping screws for securing the electrical connections are accessible only through apertures provided in the opposite ends of the housing. Recessed location of the clamping screws protects against inadvertent or surreptitious short circuiting around the switch. A flexibly attached mounting bracket includes a latch to hold the housing alongside the bracket.

Abstract: A method and apparatus are provided for fabricating battery plate envelopes from a sheet formed of microporous plastic material having a width greater than that of a battery plate to be enveloped. A battery plate is pushed edgewise into the sheet to fold the sheet about the battery plate with edges overlapping the battery plate on both sides. The folded sheet is fed with the battery plate therein into the interface between a pair of opposed pressure rollers each of which include a pair of axially aligned sealing wheels. A continuous seal is formed between the overlapping edges of the sheet by compressing the edges into one another between the sealing wheels. Each set of sealing wheels may comprise gear teeth whose teeth continuously mesh with those of the teeth mounted on the opposing pressure roller.

Abstract: A method for using comminuted lignocellulosic waste material such as flake-like wood and bark chips which have been stored outside includes placing the material in a filter bed by movement in a first direction, and thereafter passing polluted effluent gas from a boiler furnace, for example through said filter bed in a direction generally perpendicular to said first direction to filter pollutants from said effluent gas and simultaneously dry the comminuted lignocellulosic waste material. During drying of the material a portion of the material on the gas outlet side of the filter bed, toward which the effluent gas proceeds, is maintained at a moisture content which is greater than the average moisture content of the lignocellulosic material at the time it is placed into the filter bed. The lignocellulosic waste material is thereafter used as furnace fuel or as a furnace for an industrial process.

Abstract: A side shifter having a quick-mounting anchor bracket for mounting on a conventional hook-type lift truck carriage without the need for welding of any side shifter components, such as a hydraulic ram anchor, to the lift truck carriage. The side shifter features alternative upper and lower hydraulic ram anchors and interlocking relatively movable components which are prevented from disassembly when the side shifter is detached from the lift truck carriage. Friction-reducing bushings for accommodating the transverse sliding motion of the side shifter are engaged with the quick-mounting anchor bracket in such a way so as to prevent not only transverse motion but also upward motion of the bushings which might otherwise occur under the influence of the load moment. The side shifter features lower hook assemblies capable of supporting the side shifter at an elevated position when detached from the lift truck carriage, and capable of exceptionally fine vertical adjustment.
