Abstract: ABSTRACT This invention relates to a device at a dust filter for cleaning a gas flow from dust. The dust filter consists of an electrostatic precipitator or fabric filter (bag filter) and comprises a filter chamber (10) with gas inlet 112) and gas outlet (13). At the gas inlet a precollector (30) in the form of a louvre collector (31) is located for separating coarse dust, i.e. dust with a diameter exceeding 50-75 µm. In the order to obtain good collection at the louvre collector (31), the collected dust is evacuated by means of a partial gas flow, which is passed to a dust hopper (34) and a dust discharge unit (35). According to the invention, the dust discharge unit (35) comprises a cyclone collector (36), the inlet portion (37) of which is integrated with the dust hopper (34), and the outlet portion of which or central pipe (38) is formed with a passageway (39), the mouth (40) of which is located in the filter chamber downstream the louvre collector. The cyclone collector (36) is dimensioned so that the pressure drop over the louvre collector (31) amounting to between 150 and 300 Pa is sufficient to drive the partial gas flow through the cyclone collector, which may be an axial cyclone or a tangential cyclone.

Abstract: DESCENDING ACCUMULATOR FOR AUTOMATIC CASE PACKER     Abstract of the Disclosure An apparatus is disclosed for automatically stacking and progressively accumulating a plurality of identical articles so that they can be loaded as a unit into a shipping container.  The apparatus comprises a pair of indexing chains guided in low-friction tracks on a descending angle and driven by sprockets which are indexed periodically by a rotary drive. A series of trays is supported between the chains, each tray being sized to accommodate a full case load of product.  The descending angle of the chains is such that the trays on the upper side of the chains are always arranged horizontally to form descending accumulation stations at levels that are spaced apart by a distance equal to the height of the product. Infeed conveyor belts are located on one or both sides of the accumulation stations for bringing in the articles to be stacked, and a lateral, horizontally directed actuator is provided to transfer them from the conveyor belts to the trays. At the lower end of the chains, each fully accumulated unit of articles is transferred laterally by another actuator to a platform, such as an elevator, for loading into a shipping container.

Abstract: METHOD AND APPARATUS FOR MAKING                  FILTER SOCKS Abstract of the Disclosure Apparatus for making milk filter socks from a longitudinally folded sheet of filter paper.  The sheet of filter material is continuously fed along a conveying path past an ultrasonic welder which bonds together its free longitudinal edges.  A stop mechanism located down-stream from the ultrasonic welder intermittently stops the sheet of filter material so that a second ultrasonic welder may transversely bond the sheet, and a cutting disc may transversely cut the sheet to provide an open end tubular structure.  A dancer roll engaging one side of the sheet is slidably mounted for reciprocal movement in a direction normal to the plane of the conveying path and is located between the two ultrasonic welders.  The dancer roll accumulates or takes up the slack in the sheet of filter material being continuously fed while the downstream end of the sheet is stopped during the transverse bonding and cutting operations.  A method of making filter socks is also described herein.

Abstract: Abstract of the Disclosure Apparatus for comminuting scrap materials, par-ticularly fiber-reinforced resilient materials such as scrap tires, includes a pair of generally cylindrical cutter rolls mounted for rotation with parallel cutter discs of each roll intermeshed closely between cutter discs of the cutter roll.          The cutter discs on each cutter roll are of a series of thicknesses, and each cutter disc includes a plurality of cutter segments attached about its periphery.  Cutter segments are reversible end-for-end to present a sharp edge for drawing scrap material between the intermeshed cutter rolls.  A method of sharpening the apparatus includes removing worn cutter segments from the cutter discs, grinding lateral surfaces of each cutter segment, and thereafter fastening the cutter segments on a next thinner one of the cutter discs.  Annular clearing rings surround the shaft of each cutter roll between neighboring cutter discs of that cutter roll.  The clearing rings are free to move radially and have a large enough size to force cut pieces of scrap material radially outward from between the neighboring cutter discs.

Abstract: HEADREST FOR MEDICAL TREATMENT CHAIR                   ABSTRACT OF THE DISCLOSURE     A chair for human dental or medical treatment and having an improved adjustable headrest support.  The chair features a flat curved linear strip member which extends between the headrest and the main frame of the chair.  The strip member is guided by at least one, and preferably two pairs of opposed cylindrical guide rollers which contiguously straddle the strip member, so as to guide the motion of the strip member along its longitudinal axis, as it is displaced along its axis and towards or away from the frame, typically by a hydraulic mechanism.  This makes pos-sible vertical direction of movement of the strip member.  The hydraulic mechanism, or two mechanisms in tandem, are a pivoted floating mounting for the strip member which facilitates ready adjustment of the headrest support relative to the main frame and seat of the chair.  At least one tension spring is provided to produce smooth backdown of the piston plunger and piston head when hydraulic fluid pressure in the cylinder is reduced.  The uses for the present chair and integral headrest configuration include human dental, medical, beauty parlor, and barber shop treatment facilities and installations.

Abstract: ABSTRACT OF THE DISCLOSURE          A variable speed drive for an AC motor has features to reduce the speed of the motor if excess temperature is encountered in the variable speed drive system.  The system has a rectifier that converts AC supply voltage into DC voltage on the positive and negative rails.  Frequency switches switch the DC voltage to power conductors in a sequence and at a rate to determine the selected frequency.          The frequency switches are controlled by a DC demand voltage.          A temperature sensor provides an electrical response corresponding to the temperature in the system.  The temperature response is compared to a reference voltage, and if it exceeds the reference voltage, the comparator provides an output that draws down the demand voltage by a value corresponding to the difference.  Lowering the demand voltage lowers the speed of the motor to allow the system to cool under reduced load conditions.
