Patent number: 4642154Abstract: A heating wire embedded in any one of several types of shaped elements is fed current by an electrical control apparatus for a time interval which is a function of the ohmic resistance of the wire and the type of shaped element. The type and resistance are automatically determined in advance by measurement of the wire impedance which indicates type and of the ohmic resistance. Welding time is selected from a predetermined directrix depending on resistance, and the directrix itself is chosen on the basis of type by the impedance measurement. A count representative of the time is stored in a counter and pulsed down to zero while current is delivered.Type: GrantFiled: December 15, 1982Date of Patent: February 10, 1987Assignee: Georg Fischer AktiengesellschaftInventors: Alfred Thalmann, Ernesto Lehmann, Emil Roth, Walter Gerber

Patent number: 4311549Abstract: An improved laminator with a novel heating control system is disclosed for particular employment with laminating packets formed of an article to be laminated positioned between top and bottom leaves. When the packet is aligned in a ready position within the laminating machine, heating elements in a heating zone of the laminating machine are activated while the packet is stationary. When the heating zone attains a first temperature, movement of the packet is initiated in the heating zone. During passage through the heating zone, when the heating zone attains a second temperature, power to the heating elements is cycled so as to maintain the second temperature substantially constant. Also, to further minimize temperature overshoot, power to the heating elements is temporarily removed when the first temperature is attained. With the system of the invention, the dual problems of temperature overshoot and insufficient lamination of lead ends of the packet is avoided.Type: GrantFiled: August 11, 1980Date of Patent: January 19, 1982Assignee: General Binding CorporationInventor: Alfredo J.

Patent number: 4123950Abstract: A tape trip mechanism is featured that is easily retro-fittable to postage tape dispensing machines in the field. The tape trip device is automatically operative in response to electrical control signals generated by a digital scale, a computer, or other electrical-type mail equipment. The tape trip mechanism is mounted within the postage tape dispensing machine by fastening the mechanism into existing holes in the inside frame. A flexible cable of the mechanism actuates the machine dispensing system by rotating a shaft supporting a manual trip lever. When the manual lever is exercised, the flexible cable is caused to collapse, and therefore, the cable does not interfere with the manual operation. Thus the automatic electrical control is independent from the manual control, allowing the user a greater flexibility in machine operation.Type: GrantFiled: October 18, 1976Date of Patent: November 7, 1978Assignee: Pitney-Bowes, Inc.Inventor: Keith E. Schubert

Patent number: 4090898Abstract: A pair of thermoplastic workpieces are spin welded by placing one element in a non-rotatable, reciprocable clamp. Another workpiece is press-fit onto the first workpiece and the clamp is shifted toward a continuously rotatable collet having radially inwardly closable jaws. A mandrel extends from the collet and projects beyond the jaws to guide the workpieces between the jaws. The mandrel is axially inwardly displaceable by the workpieces, with inward movement thereof being yieldably resisted by a spring to insure that radial shoulders on the workpieces are in abutment. When the other workpiece is positioned between the jaws, the jaws are closed radially into driving contact with such workpiece to substantially instantly rotate the latter at the speed of the collet relative to the one workpiece. Frictional heat thus generated melts the interface between the workpieces. When the other workpiece is released from the jaws, it adheres to the one workpiece.Type: GrantFiled: March 2, 1977Date of Patent: May 23, 1978Assignee: Celanese CorporationInventor: Michael E. Tuskos

Patent number: 4083736Abstract: An apparatus is disclosed for mounting a filter to a valve member which is suitable for use in an aerosol container or the like. The apparatus includes a valve member holder adapted for moving the valve member between a loading position, a securing position and an unloading position. The valve member is loaded on the valve member holder at the loading position. A securing element is mounted relative to the securing position with the filter being interposed between the valve member and the securing element. The securing element secures the filter to the valve member by sonic or ultrasonic welding. The valve member and the secured filter is unloaded from the valve member holder at the unloading position. The invention may include a sensor for sensing the presence of the filter secured to the valve member for testing each of the filtered valve members.Type: GrantFiled: March 9, 1977Date of Patent: April 11, 1978Assignee: Seaquist Valve Company, Div. of Pittway CorporationInventors: Edward R. Nordstrom, Roger K. Ufferfilge

Patent number: 4009957Abstract: As a scanning element of an electrophotographic copying machine begins to move, a feed roller moves a sheet of copy paper into the bite of register rollers which are held stationary. This movement of the copy paper is accomplished in a period of time which is less than that required for the scanning element to reach a predetermined scan synchronizing point. The feed roller is then stopped so that the copy paper is slightly buckled and thereby resiliently urged into the bite of the register rollers. When the scanning element reaches the scan synchronizing point, a sensor causes the register rollers to rotate thereby feeding the copy sheet through the machine in synchronization with the movement of the scanning element. The copy machine may employ a seamless photoconductive drum or belt moving at constant speed in which case an electrostatic image is formed on the drum or belt by the scanning element. The image is developed by toner particles and transferred to the copy sheet.Type: GrantFiled: November 7, 1974Date of Patent: March 1, 1977Assignee: Ricoh Co., Ltd.Inventors: Shigeru Suzuki, Minoru Iwamoto, Koichi Noguchi, Kyoji Omi, Tatsuo Nishikawa

Patent number: 3989574Abstract: Automatic label applying apparatus comprises a conveyor for moving packages to a weigh scale and from thence to a label application station where a reciprocably movable vacuum type heated label applicator receives an appropriately printed label from a label issuing means and applies it to the appropriate package. A vacuum system connected to the label applicator holds the label thereon and also operates a pneumatic cylinder for a lock-out arm to prevent the heated label applicator from making contact with and burning a package when the vacuum system senses that no label is present. An electronic control system, including a photocell for sensing if a package is at the station and also including a limit switch actuated by the lock-out arm (and therefore indicative of the presence or absence of a label), operates to stop the conveyor after a predetermined interval of time in the event that a package is present at the station but no label is available to the label applicator.Type: GrantFiled: January 15, 1975Date of Patent: November 2, 1976Assignee: Sturtevant Industries, Inc.Inventor: Thomas S. Evans
