Patent EP-0949570-A1 (EP)
Inventor: SHINDE HIROKI
IPC: H04J13/00
Filed: 1997-07-30
Abstract: Consumption power is reduced in a digital matched
filter for determining a correlation value between a
digital signal (I o ) of 6 bits, which is synchronous with a
clock, and a despreading code sequence (C 7  C 6  C 5  C 4  C 3  C 2  C 1 
C 0 ) which includes 8 despreading codes. First to eighth
flip-flop sets (211-218) constituting a storage section
(210) are sequentially selected clock by clock by a write
selection circuit (220), and the digital signal (I o ) is
stored in the selected flip-flop set. The 8 despreading
codes are stored in first to eighth code flip-flops (231-238),
respectively, and are shifted in synchronism with the
clock. Output signals of the first to eighth flip-flop
sets are multiplied by output signals of the first to
eighth code flip-flops in first to eighth multiplication
circuits (241-248), respectively.

Patent EP-0928440-A1 (EP)
Inventor: CLARK KAREN R
IPC: G05B19/05
Filed: 1997-09-16
Abstract: An input device for a Programmable Logic Controller is taught. Briefly stated, an incoming input voltage is rectified with an input impedance being principally capacitive in order to avoid heat dissipation. This rectified power in turn cooperates with a current source such that once a set point is reached the current source current does not increase with increasing input voltage. The current source is also utilized to prevent off-state leakage current from turning on an input optocoupler by allowing most of the input current to be drawn through the current source until a turn-on threshold which is set by a zener diode is met.

Title: Color stable rosin esters and preparation thereof
Inventor: WHALEN DAVID MAYO
IPC: C09F1/04
Filed: 1997-12-11
Abstract: Rosin esters that are both light colored and color stable are produced by reacting polyhydric alcohol with an equivalent excess of rosin, in the presence of calcium bis(monoethyl(3,5-di-tert-butyl-4-hydroxybenzyl)phosphonate. As used herein, 'reacting' means to contact the reactants under conditions of time, temperature, pressure, etc., effective to achieve the desired reaction, e.g., an esterification reaction. When phosphinic acid is added to the reaction mixture, light colored and color stable rosin esters are produced regardless of whether the rosin or polyol are in equivalent excess, although preferably the rosin is in equivalent excess. It is preferred to include a phenol sulphide compound, such as Vultac® 2, with the calcium bis(monoethyl(3,5-di-tert-butyl-4-hydroxybenzyl)phosphanate, and to add the phosphinic acid incrementally after the acid number of the rosin and polyhydric alcohol reaction mixture has dropped to about 100. Excess rosin is preferably stripped from the product mixture at about 275 °C.

Abstract: A screw threaded fastener (103) has an elongate shank
(122) with a drilling tip (104) at one end and a head (123)
at the other end. A screw thread extends along at least a
part of the length of the shank. The trailing flank (116)
of the thread subtends an angle relative to the axis of the
fastener which approaches 90° and is greater than the angle
subtended by the leading flank (115). The screw is for use
in fixing sheets of material to thin metal battens (5) and
the angle between the trailing flank (116) and the adjacent
thin metal section (18) of the batten, is reduced in
comparison to a conventional thread form, which lessens the
distorting effect of the thread on the batten under
relatively high pull-out loads.

These variations are corrected by an adapted form of the cool diaphragm (5), which smoothes and/or reduces over the length of the sensor (6) the photometric inefficacy.
