Abstract: A biplanar posting device having a board with a rear edge and a front edge and lines passing from the rear edge toward the front edge diverging toward the front edge and intersecting the front edge at an angle of about 70 degrees with a plate fixed to the upper surface of the board having end planar portions held in contact with the board and central diverging portions in the form of two flat planes diverging from the upper surface of the board at about 4 degrees and intersecting the planes in contact with the board at a line that overlays the diverging lines. An orthotic properly placed on the device and packed with plastic beneath the heel portion will inherently be formed with a lower surface to correct a defect in the bones of a patient.
Abstract: A muffler for dissipating the sound component in exhaust gases from an internal combustion engine or the like is disclosed which has an enhanced useful life. The muffler includes a partition positioned across an incoming stream of exhaust gases. The partition is formed with stream dividing or splitting means which positively divides the stream into portions that can be more evenly directed throughout the muffler. This prevents destructive preferential flow of gases within the muffler. Additionally, shielding of sound absorption material in the muffler is accomplished by selecting the pattern of perforations to reduce the contact of such material with high velocity gases.
Abstract: A power torque wrench operated by pulling a flexible tension element tangentially from a drum which is connected through ratchet means to a coaxial driver and having a second tension element wrapped around the drum in the opposite direction so that the work stroke of the motor winds the second tension element around the drum and the return stroke of the motor winds the first tension element around the drum.
Abstract: A foldable dolly in which the arms are rotatably mounted to the frame preferably by means of interengaging sleeves formed with opposed ramps and opposed shoulders and positioned in relatively vertical alignment such that the ramps and shoulders of the first sleeve mate with the ramps and shoulders of the second sleeve. The sleeves are thereby found to permit rotation of the arms between a folded, collapsed position and an extended deployed position, while at the same time providing enhanced rigidity and stability of the arms at the extended, deployed position.
Abstract: An improved thermally actuated diffuser is disclosed. The diffuser comprises three thermal sensor actuators. A first thermal sensor actuator is responsive to changes in the room air temperature and is engaged when cool air is supplied through the duct into the room. A third thermal sensor actuator is responsive to changes in the room air temperature and is engaged when warm air is supplied to the room. A second thermal sensor actuator is responsive to changes in the duct air temperature and brings either the first or second thermal sensor actuator into engagement with the diffuser when the appropriate temperature of air is supplied through the duct and disengages the thermal actuator not being used with that duct air temperature.
Abstract: The invention concerns a three-knife trimmer, in which for the purpose of cutting on three sides stacks of books, brochures, or the like, first the side knives and then the front knife, or vice versa, are operated to carry out the cut by a single-revolution shaft, during one revolution, by means of intermediate gears at a single location, whereby the drive system for the knives consists of a guide unit and an operating unit preceding it, which operating unit is comprised of a gear unit (13, 14, 15, 16, 17) with a gear ratio that changes during one revolution of the single-revolution shaft (12). This yields a simple gear system with few parts that is simple in construction, is stable in the path of transmission and shows a harmonic motion pattern, so that the machine can operate at high speeds.
Abstract: A thermally powered change-over diffuser is disclosed which includes a housing having an outlet and movable blade assembly mounted with respect to the outlet for displacement between a first position producing a Coanda flow across a surface, such as a ceiling, and a second position producing a detached stream in a generally normally extending direction with respect to the surface. The diffuser is preferably thermally powered and includes a rapid change-over assembly enabling substantially immediate shifting between the two positions so as to provide a cooling mode of discharge and heating mode of discharge. Additionally, means for adjusting the volume of air discharged is provided.
Abstract: A nebulizer in which the feed to the spray nozzle is through a narrow space between the flat bottom of the liquid reservoir and a flange fixed to the bottom of the spray nozzle, where the space is narrow enough to draw liquid toward the spray nozzle by capillary action and aspiration at any orientation of the nebulizer between vertical and horizontal.
Abstract: A device for cutting blocks including a flat plate having an upward extending saw guide at one end and a fixed flange at the other with the distance between the saw guide and the flange being the length of a standard block, the device also including an adapter with a flange that is positionable between the first flange and the saw quide a distance preset for cutting another standard size block.
Abstract: The invention concerns a three-knife cutting machine, in which dogs on a conveying chain in machine tempo transport the material to be cut from a magazine and into a transfer station, in which pushers moveable in the direction of transport take over the material to be cut and transport it up against stops in the cutting station, in which besides two back stops two stops for the head and foot sides of the delivered cutting material are provided, whereby the stops are moveable in machine tempo back into the transfer station and again into the cutting station and, for transport of the cut material from the cutting station, further stops are located before the first stops in the direction of transport and capable of moving together with the latter, the further stops being located at such a distance from the first stops that the further stops assume a carrying position in the cutting station for the cut material which is lying there when the first stops are located in the transfer station, and whereby all stops ca
Abstract: The device for the treatment of the eyes with a washing or bathing liquid consists of a container, which possesses a cover, in which are located two vertical whirlpool tubes as washing devices, spaced to accommodate the two eyes, in the interior cross section of which is located a whirlpool device to generate bubbles as in the manner of a whirlpool bath. The cover carries the whirlpool tubes with intake. Only the washing liquid is located in the container.
Abstract: The wheel mounting of the present invention is designed particularly for use in cable car structures at intersecting street corners, that is, where the cable is carried around a curve. The structure comprises, briefly, a pair of normally vertically spaced horizontally extending supporting pleats and a vertical shaft fixed to the plates and which journals a cable supporting wheel, the later being thus normally mounted to rotate in a horizontal plane. The structure is intended for mounting in below ground surface at the elevation of and to support the car driving cable. Of particular importance is the provision in mounting of a bearing in the wheel hub surrounding the shaft and which has an outer race at the hub wall of the wheel and an inner race at the shaft, the two races being rigidly clamped to the hub and shaft so as to positively confine the forces imposed on the bearing to those forces which the bearing is designed to withstand without undue heating, wear or deterioration.
