Title: Method and apparatus for gluing closure flaps of a carton on a continuously moving conveyor
Inventor: CHROMOWSKY DANIEL L
IPC: B65B51/02
Filed: 1991-11-22
Abstract: ABSTRACT     A leak resistant carton is formed from a cardboard blank by folding the blank to an open-ended carton.  The carton is positioned on a core support member and a flexible sheet of closure material is placed over one of the open ends of the carton.  A platen above the open end of the carton is actuated to fold and seal the edges of the sheet material over the sides of the carton to close the carton.  The carton is then inverted on a conveyer and passed through a filling station, glue station and flap closure station.  The carton is first filled and the side flaps are folded inwardly.  A glue head assembly traverses the carton diagonally to apply a transverse bead of glue on the carton flaps.  The remaining carton flaps are then folded inwardly to close the carton.

Inventor: BACKSTRAND JON E
IPC: H02P5/74
Filed: 1992-01-31
Abstract: The invention is an improvement in an AC adjustable frequency load-moving system of the type having a control circuit providing a motor speed signal and using command ramps to control each of plural AC squirrel cage motors. The invention helps assure substantially equal load sharing by the motors.  The improvement includes a dwell circuit which maintains the motor speed reference signal at a synchronizing value at least for a period of time denominated as the dwell time.  This permits microprocessors -- which may be running asynchronously --to both "read" the same value of motor speed signal even though such value may be read at slightly different instants.  Separate inverter units monitor such signal and responsively generate synchronized command ramps to effect load sharing.  The invention is suitable for use with a wide variety of plural-motor drive systems and has been found to be particularly suitable for use on crane hoist systems.

Abstract: Finely particulate Zeolites of the ZSM-5 family, exhibiting characteristic peaks in an X-ray powder diffraction pattern, are stably produced by a novel method in which a nucleating slurry containing semi-crystalline zeolite having a BET surface area of 100 to less than 250 m/g is mixed with a raw material mixture of silica, alumina and alkali metal sources to obtain a preliminary slurry, followed by heating to obtain a first precursory slurry mixture containing a precursory zeolite having a BET surface area of 100 to 200 m/g, and subsequently the first precursory slurry mixture is mixed with a raw material mixture as mentioned above to obtain a second precursory slurry, followed by heating to obtain a product slurry containing a finely particu-late zeolite having a BET surface area of at least 250 m/g.  In the method, the first precursory slurry mixture can be advantageously recycled and used as a nucleating slurry.  The zeolites are advantageously utilized as catalysts, for example, as a catalyst for hydration of olefins, and also as an adsorbent, a molecular sieve, an agent for soil improvement, a filler for paper and an agent for waste water treat-ment.

Abstract: TRANSPORTATION CONTAINER WITH HOPPER BOTTOM DISCHARGE ABSTRACT OF THE DISCLOSURE         A  transport  container  for  particulate  material includes a pair of hoppers arranged end to end and mounted on a frame structure for carrying upon a truck frame.  The frame structure includes a pair of rails extending longitudinally at a  width  equal  to  the  width  of  the  truck  frame  and  thus narrower than the upper part  of the hoppers.   Each hopper includes a hopper bottom converging to an apex and an auger discharge  arrangement  projecting  from  the  apex  upwardly through the interior of the hopper and breaking out through a cover of the hopper.  The hopper is arranged asymmetrically so that the apex is spaced from a centre line of the hopper and from  one  side  wall  of  the  hopper  to  a  position  directly overlying one of the longitudinal rails of the frame.  At the apex is provided a discharge opening with a sliding door, the opening allowing the material to be discharged over the side rail downwardly toward the ground for collection.   A chute separate from the hopper wall can be attached onto the side wall  at  the discharge opening for controlling discharge for example to an auger hopper.

Abstract: The highway and railroad culverts, with or without modification, have been susceptible of being blocked by the natural instincts of beavers, causing flooding and conditions hazardous to human life. In this invention, the culvert opening Is modified by an up-stream excavation of a reservoir and the attachment of a beaver-proof device to the existing culvert. This device consists of a vertical inlet extending Into a dug-out reservoir to a depth sufficient to conceal the bottom flow of the water from beavers. The device also conceals the culvert opening where beavers usually start their dams. The water flow is not restricted as the device allows water to flow through the existing culvert at its maximum capacity. The device is adaptable to round or square culverts and can beinsulated to control winter ice build-up. A steam pipe is installed in the unit for the use of steam in spring to thaw ice if necessary.            The unit is adaptable for different size culverts.

Title: Osd circuit for displaying advertising picture data
Inventor: RHEE PIL G
IPC: H04N5/445
Filed: 1993-02-19
Abstract: Abstract of the disclosure An OSD circuit for displaying advertising picture data on the screen of a television receiver is disclosed,   and the circuit includes:   an oscillator,  a first counter,  a second counter,   a third counter, an F/F circuit,   a ROM,   and an automatic color adjusting means.  The oscillator supplies clock signals to the first counter,  and the first and second counters supplies horizontal and vertical scanning addresses to the so as for the advertising picture data to be outputted from the ROM.   The third counter  supplies a delay signal for displaying of an advertising picture data of a picture scene at a time, thereby inhibiting the output of the ROM for a certain period of time.     The  F/F  circuit  prevents  a  dual  display  of the advertising picture  on the screen,  and the ROM  stores the advertising picture data separately for main color data, first sub-color data,  second sub-color data and brightness data.          The automatic color adjusting means  receives the advertising data consisting of the main color data,  the first sub-color data and the second sub-color data from the ROM,   and supplies an advertising picture having a color definitely contrasting to the color of the picture of the currently broadcasting program.          If the OSD circuit of the present invention   is applied to television receivers,  not only advertising picture data can be continuously displayed  for  a  certain  period  of  time  in  a successive manner,   but also a clear and harmonized  picture color can be obtained.
