Patent ZA-802308-B (ZA)
Title: Pollution abating,energy conserving glass manufacturing process
Inventor: HOHMAN C
IPC: C03B3/02
Filed: 1980-04-17
Abstract: Some free water containing glass batch agglomerate formulations when attempted to be dried and heated in a vertical bed (3) prior to being discharged to a glass meter (1) for vitrification convert into large aggregates which cannot be suitably supplied to the melter. The present invention solves this process disabling aggregate formation by treating such agglomerates in a preconditioning chamber(s) (11, 21, 31, 41) prior to supplying them into a vertical bed (3) so as to preclude serious aggregate formation in either the preconditioner or the vertical bed. Such treatment is employed in manufacturing glass with a fossil fuel fired melter or an electrically operated melter.

Title: Locking mechanism with actuator
Inventor: SEDLEY BRUCE SAMUEL
IPC: E05B13/00
Filed: 1987-02-24
Abstract: A coded card key (14) is insertable through a slot (15) to bring into alignment coded magnetic areas on the card with magnetic pins (28) of the lock to unlock a core (24) relative to a locking plate (21) and enable the core (24) to be driven downwardly by the card engaging its lower flange (26) and to actuate an apparatus, typically a door-lock.   The core (24) has a cam having a first cam part (54) which is engageable by the card (14) and a second cam part (55) which abuts a limit spring (56) when the core (24) has reached the unlock position, whereby the core (24) keeps the unlock position as long as the card (14) engages the cam part (54). Withdrawal of the card (14) by the user allows return movement of core (24). The user can release the card for actuating e.g. a door-knob, instead of having to hold the card down in the lock while rotating the door-knob. <IMAGE>

Title: Wire processing apparatus having control means
Inventor: DUSEL ROBERT O
IPC: G01N21/892
Filed: 1986-10-03
Granted: 1990-10-10
Abstract: Wire processing apparatus employs a conveyor for transporting wire segments to a series of wire processing machines which strip insulation from the wire segment ends and then subsequently attach electric terminals to the stripped ends. A quality control device located between the insulation stripper machine and the terminal attachment machine inspects each stripped end and, if it does not meet desired tolerances, sends signals which prevent the terminal attachment machine from operating upon the defective stripped end as the conveyor moves the wire segment therepast. The quality control device comprises an illuminated field at which the stripped end momentarily stops, an optical lens opposite the illuminated field for providing an optical image of the stripped end, and a converter for converting the optical image to an electronic image signal. Solid state electronic circuits compare the image signal to a reference signal, provide an error signal if the stripped end is defective and store the error signal in a memory circuit. The error signal, if present, is recalled from the memory at the appropriate time and converted to an output signal which prevents the downstream terminal attachment machine from operating on the defective wire end.

Title: Memory error correction
Inventor: KIM JIN-KI
IPC: G11C29/42
Filed: 1992-12-31
Granted: 1996-01-17
Abstract: An electrically erasable programmable read only memory (EEPROM), having error checking and correction circuitry uses a separation circuit to electrically isolate a temporary page buffer memory from a memory array so that better reliability of parity generation and error correction is provided. The EEPROM memory array includes a plurality of bit lines, a plurality of memory cells respectively connected to the bit lines and parity cells. The error check and correction circuit includes a column gate logic, connected to the plurality of bit lines, for temporarily loading randomly input data onto a memory page buffer. The EEPROM processes the data in the page buffer to logically store it as multi-byte data, simultaneously together with appropriate parity bit data corresponding to each multi-byte data set, in the memory array. Because data randomly input to and from the page buffer is selectively, electrically isolated from the memory array, bit errors that would otherwise be caused by defective memory cells, or bit lines, within the memory array, are compensated for in advance.
