Patent KR-930007345-B1 (KR)
Title: Textile yarn creel
Inventor: GUTSCHMIT ALAN
IPC: D04B15/42
Filed: 1985-02-15
Granted: 1993-08-09
Abstract: A textile yarn creel having a circular supporting framework and plural yarn package supporting members mounted removably and circumferentially slidably thereabout and axially thereof, the supporting members having plural radially inwardly extending pins for mounting of yarn packages thereon for radially inward yarn withdrawal. Guide eyelet members are mounted in a circular arrangement on the circular framework radially inwardly spaced from the package supporting members for receiving the yarns and for direction therefrom to an associated textile machine e.g. a multi-feed circular knitting machine. The package supporting members may be selectively mounted at substantially any locations and spacings circumferentially about the framework for selective expansion and reduction of the creel capacity without changing the floor space occupied. In one embodiment, pivoted arms carry the package supporting pins while in another embodiment the package supporting members are selectively movable radially of the circular framework as well as circumferentially thereabout. The circular nature of the creel and the adjustability thereof give it substantially greater capacity per unit floor space occupied than any known conventional creel. A rotating compressed air blowing arrangement is intermittently operable for removing and preventing lint accumulation on the creel.

Title: Track access method for optical diskdriver
Inventor: JO HON-CHOL
IPC: G11B7/08
Filed: 1988-10-11
Granted: 1995-06-07
Abstract: The method makes use of an up/down counter and a disk eccentric value for searching for a target track of the optical disk driver. A CPU(10) calculates the number of tracks between the current head position and a target track, and set the calculated number to a track counter(40). If the optical head approaches to the target track, the CPU controls a down control port to decrease the counter value. When SM is a fine state, a multiplexer selects FD and generates the signal to execute a tracking actuator in a optical pickup module.

Title: Frequency, phase and modulation control system which is especially useful in simulcast transmission systems
Inventor: SANDAHL JOEL
IPC: H03L7/00
Filed: 1989-10-24
Granted: 1998-10-01
Abstract: A system enabling the frequency, and if desired, phase control of an oscillator which generates a standard signal useful as a carrier which is modulated by modulation signals. A multiplicity of such oscillators and associated transmitters may be used in a simulcast transmission system which covers a large area, for example in paging applications where the transmissions must be of the same frequency or with predetermined frequency offsets and be matched in modulation in order to prevent interference and distortion in areas where the transmissions from different transmitters overlap. The transmissions originate from a station which may be remote from the transmitters. The station has a system controller and the transmitters have transmitter controllers. For frequency control a reference signal generated in the system controller is transmitted over the same link and band width (e.g. the voice band width) with the voice modulating signals to the transmitter controllers of all of the transmitters. This reference signal may be corrupted by noise and other error signals. It also may be transmitted or received intermittently during periods when transmissions are quiet and traffic is light. At the transmitter controllers, multiplicities of phase measurements are made a plurality of times, each time during an interval of predetermined length and at predetermined rates. From these measurements statistical values of phase, deviations and times of occurrence are collected and used to provide error control signals in terms of the ratio of phase difference to time, notwithstanding that the reference signals may jitter in phase and amplitude due to noise and other errors and also notwithstanding that the phase measured at various of the times may include a multiplicity of phase wraps (the phase difference being greater than one cycle or 360 DEG .) A frequency error may be offset, or if offsets are not used, the frequency errors may be applied to the standard oscillator to lock the phase thereof in predetermined relationship with the reference. For modulation control, each transmitter is keyed with modulation calibration signals. These signals are transmitted to the system controller where they are correlated, and codes representing deviations from matched correlation characteristics (delay, gain and frequency spectrum) are transmitted to each transmitter where modulation signal correction circuits are conditioned to process the modulating signals so that the transmissions from each transmitter will be matched in modulation characteristics.

Abstract: The rubber compsotion comprises 40-90 phr of carbon black, more than 1.5 phr of vulcanizing agent, more than 1.0 phr of vulcanization accelerating agent, and stearic acid and zinc oxide as an activating agent where the ratio of amt. of stearic acid per zinc oxide is equal or more than 0.65. The obtd. rubber compsn. is useful for tyre for a passenger car, a trunk, a bus or a agricultural machine. The obtd. rubber compsn. improves workability (eg. preventing early vulcanization), lower hysterises loss, and heat registance and ageing resistant property.
