Abstract: A broaching system comprises a plurality of sub-bars configured to receive broaching tools. The system further comprises a broaching machine and a robot, the robot being configured to mount and remove sub-bars from the broaching machine. The robot includes an arm operable in three or more axes, and an end of arm tool. A method of broaching comprises providing a plurality of sub-bars, a broaching machine, and a robot having an arm operable in three or more axes and an end of arm tool. The method further includes mounting, by the robot, a sub-bar onto the broaching machine; and performing a broaching operation using the sub-bar. Simultaneous to the performance of the broaching operation, the method includes affixing another tool to another sub-bar, and/or moving, by the robot, another sub-bar to a storage location.

Abstract: A manometer integrated into a manual resuscitator includes a housing with a communication path, and a pressure gauge integrally forming part of the housing. A sensing chamber and an atmospheric chamber are separated by a diaphragm subject to distortion by differential pressure between the chambers, with a spring to restore the diaphragm upon equalization of the pressures. A shaft journaled in a first bearing on the diaphragm and a second bearing in one of the chambers rotates in the bearings upon diaphragm distortion, and an indicator on the shaft indicates differences in pressure between the chambers.

Abstract: A vehicle is disclosed having a reduced turning radius comprising a directional wheel assembly for turning the vehicle and a drive wheel assembly for driving the vehicle. The drive wheel assembly has a first and a second drive wheel independently driven by a first and a second motor through a control circuit. A counter-rotation circuit counter-rotates the first and second drive wheels upon a major turning position of the directional wheel assembly to enhance the turning of the vehicle. A reducing circuit reduces the speed of the motors upon a minor turning position of the directional wheel assembly. The vehicle may include a slide mechanism for providing a reduced wheelbase to further reduce the turning radius of the vehicle. One embodiment of the invention includes an improved steering device for controlling the directional wheel assembly.

Abstract: An electromagnetic motor has an outer housing and a shaft rotatably mounted in the housing to extend along the central axis and out through one end of the housing. A plurality of electromagnets are mounted in the housing at spaced intervals around an annular ring centered on the central axis. An elongate rotor member of ferromagnetic material is secured to the shaft and projects in diametrically opposite directions radially outwardly from the shaft up to the annular ring of electromagnets. A power supply is connected to successive diametrically opposed pairs of electromagnets through a switching assembly such that the ends of the rotor are attracted to successive activated melectromagnets in the ring, thereby rotating the shaft.

Abstract: Apparatus for heating and humidifying respiratory gases comprise a housing, a gas permeable member and generating material. The housing includes an inlet adapted for connection to a tracheal tube and an outlet adapted for connection to a tube for passing respiratory gases. The inlet and the outlet are positioned so that respiratory gases passing through the housing pass therebetween. The gas permeable member, for example, a conventional heat and moisture exchanger member, is positioned in the housing between the inlet and the outlet and is adapted to exchange heat and moisture with respiratory gases passing through the housing. The generating material, for example, a carbon dioxide absorbing component, is located in the housing between the inlet and the outlet and is adapted to generate water, and preferably heat, available to humidify, and preferably heat, respiratory gases passing through the housing.

Abstract: A method is provided for producing a ceramic substrate with at least one surface having sufficient smoothness to allow for placement of fine line electrical circuitry. A ceramic powder is placed in a die. A ceramic tape is formed having one surface with a desired degree of smoothness. A portion of the tape is placed into the die with the surface opposite the smooth surface in contact with the ceramic powder. The powder and tape are dry pressed to form an integral ceramic green body with a smooth surface. The green body can be sintered to form a sintered smooth-surfaced ceramic substrate. The smooth-faced ceramic substrate can be formed with the smooth face countersunk or with edges pulled back. A ceramic substrate can be formed with a conductive material between the cast tape layer and the base layer. A ceramic tape cast on a smooth carrier such as polyvinyl butyral and a method for producing such cast tape is also disclosed.

Abstract: In accordance with the invention, hollow pellets having outer surfaces of one material and inner surfaces of another material are manufactured by dropping drops of liquid into a bed of powder containing the material of which it is desired to make the outer surface portions of the hollow pellets and preferably also a binder, the liquid containing the material of which it is desired to make the inner surface portions of the hollow pellets. When the drops of liquid fall into the powder, the powder immediately forms a spherical shell around each drop so as to form the hollow pellets upon vaporization of the liquid. It is preferred that the powder additionally contain some sodium bicarbonate or the like and that the liquid be an aqueous acid solution such that, upon initial formation of the spherical shell of powder, the acid reacts with the sodium bicarbonate to generate carbon dioxide which causes the spherical shell to expand while yet additional powder coalesces onto the shell.

Abstract: A new filter cell which has particular utility in an isokinetic in-stack particulate collection system can be inserted directly into standard three-inch or four-inch portholes which are prevalent in the stacks which are to be tested. The filter cell is attached to a probe, both of which are inserted into the stack so that a fluid containing the particulate enters the filter cell parallel to a fiber filter which is contained therein. The fluid passes downward through the filter fiber and then exits the filter cell parallel to the fiber filter through an outlet port, leaving the particulate matter trapped in the filter.
