摘要： A brushless d.c. motor comprising a housing, an annular stator coil structure with the housing, a rotor concentric with the stator and comprising a body having an output shaft portion extending from one end thereof toward the forward end of the housing for connection to a mechanical load for driving the same and a permanent magnet arrangement on the periphery of the rotor body operatively associated with the stator coil structure, a first bearing near the forward end of the housing for rotatably supporting the shaft portion of the rotor and wherein there is provided a second bearing axially inwardly of the rear end of the rotor for rotatably supporting that end of the rotor and a circuit board located between the rear end of the rotor and the rear end of the housing. By virtue of the location of the second bearing a rigid and vibration free structure is provided for operation of the motor at high speed. By virtue of the location of the second bearing and the circuit board potting material can encapsulate the stator coil structure and circuit board thereby completely sealing all electrical sections of the motor so that they can withstand autoclave sterilization conditions. A fluid passage arrangement equalizes pressure applied to the first and second bearings so that they can withstand autoclave sterilization conditions.

摘要： A heat exchanger having an outer shell with an elongated, semi-circular fluid duct plate mounted in the shell. A tube bundle slidable between the duct plate and the shell is fixed at one end relative to the shell. The fluid inlet and outlet configuration, and transverse fluid flow pattern, are typical of those described in U.S. Pat. No. 3,532,160. The exterior of the tube bundle is partially covered with a shrouding to contain the fluid flow within the tube bundle by allowing the fluid to exit only through the outlet side. Sealing mechanisms running longitudinally between the shrouding and the upper duct plate, and between the shrouding and the shell, provide a seal which restricts the fluid flow to a transverse flow through the tube bundle. A seal between the supported end of the tube bundle and the shrouding confines the fluid flow in the bundle and allows for relative expansion of the shrouding and the bundle. Drains are provided in the shell wall on each side of the lower sealing mechanism to allow for moisture run-off from the heat exchanger.

摘要： A method and apparatus for separating particulate matter from a gas stream wherein dirty gas is moved first through a corona discharge zone, such as that provided by a plurality of rod-like electrodes each having a sharp-edged corona producing ribbon-like formation extending axially therealong, and then is moved through a plurality of mechanical filters of the cartridge type, each comprising a perforated, cylindrical, metal outer shell and an inner filter medium of foraminous dielectric material such as pleated paper. Each cartridge is closed at one end and open at the other from which cleaned gas flows out axially. The electrodes are located circumferentially of the filters with the filter and electrode longitudinal axes being substantially parallel. The conductive outer shells of the filter elements are connected to an electrical reference such as ground and the electrodes are connected to a relatively high electrical potential in a manner generating corona discharge between the electrode formations and the filter element shells. Collected particulate material in the filter media and on the shells is removed by introducing a controlled quantity of high pressure gas at predetermined times and at a location to induce a substantial flow of gas through the apparatus in a reverse direction.

摘要： A contaminant-resistant motor may include an endbell with hermetic sealing of control components within a control module cavity in the endbell. The endbell configuration includes a front wall that isolates the control module cavity from contaminant-prone area of the motor assembly. The stator leads may be sealed within the lead passages using glass or other seals to further isolate the stator leads and control module cavity against ingress of contaminating liquids from the motor interior. The endbell configuration permits larger bearing elements to be used. A method of assembly of the motor may involve first fixture to align the stator, housing and REB to ensure concentric alignment of the stator to housing and the REB to the housing and a second fixture to isolate front and rear bearing bores and the stator inner diameter from encapsulation material and permit the stator to be molded to the housing.

摘要： A dust collector has a dirty air chamber arranged to receive a flow of dirty air containing suspended solid particulate material, a clean air chamber communicating with exhaust, and a plurality of filter bags arranged to have their interior surfaces communicate with the dirty air chamber and operative to separate solid particulate material from cleaned gas passing therethrough. The improvement includes an elongated venturi-like member arranged to service a number of such filter bags, and a conduit arranged to deliver high energy pulses of reverse air through the venturi-like member countercurrent to the normal flow of dirty gas therethrough. Such pulses of reverse air momentarily create a reduced pressure within the serviced filter bags, and induce cleaned gas to flow back through the serviced filter bags to dislodge and remove accumulated solid particulate material from the interior surfaces of such bags.

摘要： A permanent magnet activated wrap spring clutch (10). A coil spring (32) surrounds an input hub (14) and an output hub (22) and is selectively engaged to wrap down upon the hubs for the transmittal of torque. In an unpowered, engaged condition of the clutch, a permanent magnet (40) attracts a control collar (38) attached to the spring into frictional engagement with a rotating input element (20). Rotation of the control collar causes the spring to wrap down from its somewhat oversized diameter at rest to grip the hubs. In a powered, disengaged condition of the clutch, an energized coil (44) causes the magnetic field of the permanent magnet to move away from the control collar, thereby removing the frictional engagement and allowing the spring to unwrap. The clutch provides torque transmittal without electrical power and ensures complete disengagement regardless of a low momentum or high drag on the output.

摘要： A heat exchanger comprising a precooler and reheater core adjacent a chiller core, first heat transfer passages extending through both cores through which incoming air passes in a first direction, second heat transfer passages extending through the chiller core through which coolant passes in heat exchange relationship with incoming air and perpendicular to the first direction, and third heat transfer passages extending through the precooler and reheater core through which cooled air from the chiller core passes in heat exchange relationship with the incoming air and perpendicular to the first direction. A conduit conducts chilled air from the chiller core to the third set of heat transfer passages. Incoming air is chilled in the chiller core and thereafter exchanges heat with the incoming air in the precooler and reheater core to precool the incoming air to form water droplets and to raise the temperature of the chilled air to a usable temperature. The precooled and moist incoming air exchanges heat with coolant in the chiller core such that the air is chilled to a low temperature condensing water vapor therein. The first heat transfer passages include fins staggered and disposed substantially perpendicular to the flow to create an undulating pattern there along for moisture separation within the precooler and chiller cores. The crossflow arrangement of passages in the cores of the heat exchanger advantageously enables the air leaving the precooler and reheater core to enter the chiller core directly without any intermediate channeling or piping.

摘要： A surface mountable electronic device and method of making same wherein a discrete electronic device is encapsulated in a body of electrical insulating material having opposite ends and a mounting surface extending between the ends, and an electrode is provided on each end. Each electrode includes a portion on the end of the body in electrical contact with the corresponding lead of the discrete electronic device and a contact portion extending along the mounting surface for making electrical connection to a circuit portion defined on a surface to which the device is mountable. The discrete electronic device is manufactured, prior to encapsulation, by known techniques. Preferably the body is a rectangular solid with each of the four sides having electrode contact portions thereon to serve as one of four possible mounting surfaces each with substantial mechanical stability. When the discrete electronic device is an inductor, interruption of the magnetic field is minimized by spacing the ends of the inductor core from the ends of the encapsulating body, separating the electrode contact portions, having the area of the electrode end portion less than the area of the end of the encapsulating body, and having the cross-sectional area of the most narrow section of the electrode end portion no less than the cross sectional area of the magnetic wire of the inductor winding. For a shielded inductor, phenolic core inductor or non-inductive device, solid metal end electrodes can be employed.
