Abstract: A vertically adjustable mount for heavy duty machinery utilizing three wedges wherein a screw operated actuating wedge is located between upper and lower wedges. All the wedges include engaging cam surfaces obliquely related to the longitudinal direction of relative wedge movement during adjustment, and the range of vertical adjustment is extended, and quickly initially approximated, by providing the upper and lower wedges with longitudinally spaced openings, constituting sets, wherein a nut mounted upon the actuating wedge screw may be selectively positioned within a set of openings to adjust the range of actuating wedge movement while maintaining a relative short length of the actuating wedge screw.
Abstract: A stationary syphon system for heat exchanger rolls, particularly suited for use with steam heated rolls wherein condensate must be removed from the roll chamber, utilizing a pivoted pick-up conduit mounted upon a journal conduit which is rigidly supported against radial deflection by a bearing interposed between the journal conduit inner end and the roll structure. The bearing may be mounted within a tube insertable into the journal bore to facilitate maintenance and replacement, and the condensate receiving end of the pick-up conduit is very accurately positioned with respect to the roll chamber inner surface by a positive locking arrangement remotely operated at the journal outer end.

Abstract: The invention pertains to apparatus for thermally insulating selected portions of a cylindrical dryer drum, usually adjacent the drum ends, for the purpose of obtaining a substantially uniform drum shell temperature throughout its length to obtain a uniform moisture profile throughout the width of the web being dried. A plurality of cylindrical segments are bolted together within the drum interior to define a circumferential assembly biased against the drum inner surface. The segments each include a thermal insulation material engaging the drum shell preventing direct access of that engaged portion of the shell with the steam within the drum thereby reducing the exterior temperature of the drum shell at the location of the thermally insulated segment. The segments may be bolted together, widthwise, to increase the axial dimension of the temperature controlling segment assembly.
Abstract: A transmission system for louver type signs wherein the signs consist of a plurality of multiple faced louvers having indicia defined thereon and the side-by-side relationship of the louvers permits pre-selected faces to define a completed image and simultaneous partial rotation of the louvers presents a new visible image, and wherein, each louver is operated by a separate "T" drive bevel gear transmission having an output shaft upon which a louver is mounted operatively connected to a drive shaft perpendicularly related to the output shaft. The drive shafts of adjacent transmissions are interconnected and a plurality of transmissions are simultaneously operated by a single motor drive source. The cost of the transmissions is significantly reduced by the use of a unique bearing support system for the drive and output shafts eliminating the need for separate bearings in that the material of the transmission casing constitutes the shafts' bearing surfaces.
Abstract: A vehicle tilt-out window with a resilient seal insert includes an annular frame which is bonded to the vehicle window opening. The frame includes a resilient double lip seal which is molded into a recess formed in the frame and the lip seal cooperates with a glass panel mounted upon the frame by homogeneous hinge tabs extending from the frame permitting the glass panel to be tilted relative to the frame for ventilation purposes and an articulated pivoting latch mounted to a homogeneous latch base locks the glass panel against the lip seal.
Abstract: A dynamic vibration absorber for a rotating machinery element preferably of the bifilar pendulum vibration absorber type wherein the absorber system includes one or more pair(s) of masses having identical paths of movement relative to the axis of the rotating element whose vibrations are being absorbed, the individual absorber masses of a given pair moving out-of-phase with respect to one another relative to the rotating element wherein a disturbance torque with a frequency that is a multiple of the rotation rate of the rotating element is absorbed by a one-half relative frequency motion of the corresponding half-order absorber pair. The half-order absorber pairs are driven primarily by centrifugal forces, move with a frequency one-half that of the disturbance torque and use non-linear Coriolis forces as the source of the counteracting torque.
Abstract: An air diffuser system for a medical thermal blanket wherein air forced over an elongated heat exchanger is substantially uniformly distributed over the heat exchanger and a thermal sensor located downstream over the heat exchanger to eliminate localized hot and cold "spots" and permit accurate temperature measurement of the air and provide an effective exchange of heat between flowing air and the heat exchanger, the apparatus of invention is characterized by its concise configuration and dimensions.
Abstract: A chair having a reclinable back having a seat and back interconnected by a stiff resiliently flexible transition connection connecting the seat rear portion and the back lower portion, the seat forward portion and back portion being mounted upon a support whereby reclining of the back raises the seat rear portion producing an occupant weight operated reclinable chair having a substantially uniform back reclining force requirement throughout the reclining range of motion.
Abstract: Apparatus for processing machine tool coolants wherein the used coolant fluid includes emulsified oils of light density or the like to be separated from a heavier density metal working fluid such as oil or water. The apparatus also removes particles, bacteria and odor from the processed fluid. Contaminated used coolant is prefiltered of particles prior to passing through a coalescer separation reservoir consisting of a plurality of adjacent configured plates permitting the low density emulsified oils to rise to the surface of the liquid within the separation reservoir. The emulsified oils pass over a weir and are drained away, and the skimmed coolant fluid passes from the separation reservoir to an accumulation reservoir whose level is sensed by a float controlling a pump which removes the coolant fluid from the accumulation reservoir and passes the fluid through a fine activated charcoal filter to complete the processing.
Abstract: A disposable pneumatic thermal blanket for controlling a patient's body temperature wherein the blanket includes structure for providing access through the blanket for surgical purposes. The inflatable blanket consists of upper and lower thermoplastic sheets heat sealed at the periphery and specified locations and sealed slits within the blanket central region permit access to a patient without loss of temperature controlled air. The blanket includes strategically placed adhesive strips or patches to aid the positioning of folded blanket access portions, or positioning of the blanket on the patient, and the location and relationship of the slits permit a variety of shapes and sizes of access openings to be selectively formed.

Abstract: A self adjusting support for anti-friction bearings wherein one half of the circumference of the outer race of the bearing is accurately positioned by a semi-cylindrical recess formed in a bearing support half having a diameter equal to that of the bearing outer race, and the other half of the bearing support comprises a retainer having a semi-cylindrical configuration recess of a larger diameter than the outer race and a deformable wall wherein upon using tension members to draw the bearing support half and retainer toward each other the retainer wall will deform and cause the recess to conform to the diameter of the bearing outer race to accurately maintain the anti-friction bearing within the bearing support permitting the bearing to be firmly held in position without auxiliary cages, bushings or split rings even though significant tolerances may exist between the bearing support and bearing outer race.
