Title: Yarn package transport system
Inventor: TSUZUKI KIYOHIRO
IPC: B65G47/70
Filed: 1996-04-30
Granted: 2000-03-21
Abstract: A  package  transport  system   (1)   is  provided  for transferring yarn packages from a textile machine  (2)  to a transport conveyor (4).  Textile machine (2), which is either an open end spinning machine or a winding machine, has conveyor belts  (14,16)  for transporting yarn packages from rows of spinning stations or winders to chutes (18,20), afterwhich they fall by gravity onto transport conveyor (4).  A delay mechanism comprising controller  (C);  sensors  (100,102)  connected to controller  (C);  and switches  (110,115),  also connected to controller (C), prevents yarn packages delivered via chutes (18,20) from colliding.  If textile machine (2) is a winding machine, yarn packages traveling from winders to chutes (18,20) have a sharply angled narrow portion on one side, making them easily susceptible to unwinding and tangling if the angled side is the first to enter chutes  (18,20).   In this scenario, a reorienting mechanism can be employed to rotate the yarn packages 180~ prior to their entrance into chutes (18,20).

Abstract: A hydraulic fastening device, for securement of two components, for example, securement of teeth to a bucket on earthmoving or mining equipment. Each component (29 and 51) has an orifice (50 and 52) therein adapted to be substantially aligned. A body member (26) is inserted in the aligned orifices (50 and 52). A control means (34) is then operated to move at least one protrusion (40 and 41) to protrude from the body (26) and to fasten the components (29 and 51). This is achieved by hydraulic operation and connection of a fluid conduit (32) between the control means (34), e.g. a grease nipple, and the protrusions (40 and 41).

Granted: 2004-12-21
Abstract: A method of forming vehicle wheel rims includes utilizing linear friction welding. A generally planar piece of metal material (20) is placed into a coil position with two ends (22, 24) in abutment. The abutting ends are oscillated or moved, in a generally linear pattern (32), relative to each other to increase the temperature of the metal at each end. After the temperature has been increased sufficiently, without reaching the melting temperature of the metal, the linear motion is stopped. The ends are then aligned precisely and forced together with an increased axial load (34). After cooling, the two ends are permanently joined together with an essentially defect-free welded joint.

Granted: 2001-06-19
Abstract: A harmonic mitigating device connected between the power distribution system and the load provides a flux shifting multiple-winding reactor with a capacitor bank connected between the reactor windings. At least one line winding is oriented in a first polarity on a core, and at least one compensating winding oriented in the opposite polarity on the core and connected between the output of the first winding and the load. The opposing fluxes generated by the line winding and the compensating winding cancel and thus reduce the through-reactance of the device between the load and the power supply. The input of a cross-link circuit comprising a capacitor is connected between the line winding and the compensating winding.  The reactance through the cross-link circuit to the neutral (or another phase) is lower than the reactance through the line winding. Harmonic currents thus flow through the cross-link circuit, and are largely prevented from penetrating the power distribution system.

Abstract: Apparatus and methodology for radio utility meter reading processing of data acquisition for use with an automatic billing system involves a utility meter transmitter antenna system installed at or near ground level. An RF utility meter communication apparatus transmits utility meter data to a remote utility meter data collection unit from an underground pit box. The pit box includes a utility meter and has a generally ground level pit lid with an opening therethrough. An antenna element has an upper member extending at least partly through such pit lid opening. A depending base of the antenna element extends from the upper element and passes through the pit lid opening into the underground pit box. The depending antenna element is capacitively coupled or provided with some other form of non-mechanical coupling to the output of an RF transmitter also included within the pit box. The antenna element components are nested for ease of attachment to or removal from a pit lid, with a rotatable threaded nut received about a depending antenna element for drawing tight against the underside of the pit lid, with an upper antenna element received above such pit lid. An antenna element may be directly coupled with a metallic pit lid so that such metallic pit lid functions as part of the antenna. Alternative embodiments may be provided for structure of the antenna element, so as to minimize the structure and components needed for removably securing or installing the antenna arrangement, supported on the removable pit lit of a conventional pit box.

Abstract: A food product is heated by maintaining the food product in an AC electrical field provided by an RF signal at an RF frequency that matches a Debye resonance frequency or frequencies of one or more components of the food product. As the food product warms, the frequency of the RF signal is automatically adjusted to track changes in the Debye resonance frequency, which shifts in frequency as the temperature rises. Individual regions of the food product can be heated, by the use of grid electrodes, at different rates to assure uniform warming or to achieve a particular desired warming pattern.
