Patent EP-0101509-A4 (EP)
Title: Ultrasonic transducers.
Inventor: FU CHONG-CHENG
IPC: G10K11/26
Filed: 1983-02-16
Abstract: Transducer structures for use in volume flow measurements which generate a first uniform beam and a second focused beam within the uniform beam. The transducer may include concentric elements (22, 24, Fig. 3), a linear array (Fig. 8) or combinations thereof (Figs. 10a-10c). In a two element concentric array (Fig. 3), a central disc (22) generates a uniform beam and a peripheral annular element (24) having a lens (28) thereon defines a second focused beam within the first beam. In a linear array (Fig. 8) a plurality of juxtaposed linear elements (50) define a scan surface and a segmented element (52) within the linear element array defines a focused reference sample volume within the scanned surface. A concentric array (Fig. 5) having a plurality of annular elements is driven with amplitude weighting of each element in accordance with a Fourier-Bessel aprroximation to the desired beam pattern thereby electronically achieving ultrasonic beam width control.

Title: A process for partially hydrolyzing epoxy resins in the absence of an organic solvent and in the presence of a dicarboxylic acid and a phosphonium compound.
Inventor: CAVITT MICHAEL BRENT
IPC: C08G59/14
Filed: 1983-08-04
Abstract: Process for hydrolyzing an epoxy resin by reacting said epoxy resin with water in the presence of a catalyst. This invention is characterized by conducting the reaction in the absence of a polyhydric phenol and substantial quantities of an organic solvent and in the presence of a catalytic of a catalyst comprising (1) at least one dicarboxylic acid and (2) at least one phosphonium compound wherein the molar ratio of (1) to (2) is from 1:1 to 20:1. Hydrolyzed epoxy resins produced by the process of this invention are useful in coating compositions.
Patent EP-0188461-A4 (EP)
Title: Liquid flow controller having pressure balanced piston for delivering constant flow.
Inventor: KENT PREBEN H
IPC: G05D7/01
Filed: 1985-06-10
Abstract: A small, lightweight, simple, and highly reliable flow controller (2) utilizing two moving parts (6, 48), for apportioning inlet fluid flow between an orifice outlet (26, 16) and inlet. Constant outlet flow over a substantial inlet flow and pressure range is achieved through the use of a flow balanced flow control piston (6) reciprocating internally of a housing (4). The balanced piston is biased to a predetermined proportioning range through an internal spring (48). The unit is normally operated with inlet port and outlet pressure sensing port in fluid communication with an external orifice (24). A bypass port (14) communicating with the controller inlet adjacent the control piston returns excess fluid to the reservoir (22) of a pumped fluid system. Increases in inlet flow to the regulator/orifice combination act to adjust the balanced piston position and initiate or increase flow across an integral piston/seat control orifice. The downstream or outlet pressure of the external orifice is sensed by an equal piston area distal the cylinder seat and/or inlet side of the piston. A damping piston (50) abuts said inlet pressure sensing portion of the piston in order to minimize transient piston motion or chatter.

Title: In-folded fin seal end closure.
Inventor: LISIECKI ROBERT E
IPC: B65D5/08
Filed: 1985-07-15
Abstract: A flat end closure arrangement for a thermoplastic coated paperboard container, and the blank therefor, wherein four sets of dual, oppositely skewed, supplementary score lines (82, 84, 86, 88, 90, 92, 94, 96) are formed on two sides of the resultant end closure, such that they are adapted to be folded into position just inside the usual horizontal score lines (16) separating the end closure panels from the sidewall panels. These supplementary score lines provide a second, substantially 90<o> bend for the paperboard layers, supplementing a 90<o> bend about the respective horizontal score lines, in lieu of each usual 180<o> bend about the respective horizontal score lines, thereby diminishing the chances for cracking of the thermoplastic coating at the bend locations.

Patent EP-0292573-A4 (EP)
IPC: H02P5/00
Filed: 1987-12-11
Abstract: Régulateur de vitesse dans lequel les données de réaction nécessaires pour la commande de la vitesse d'un servomoteur sont reçues par un codeur d'impulsions sous forme de données discrètes et subissent un traitement numérique par un microprocesseur pour obtenir des commandes de régulation prédéterminées. Lors de l'échantillonnage des données avec une cadence d'échantillonnage prédéterminée compatible avec le traitement par le microprocesseur, l'élément de retard à l'instant où les données sont reçues par le processeur sous forme de données de vitesse rend imprécise la commande du servomoteur. Par conséquent, une unité (5) formant un signal de détection traite les données de comptage discrètes de manière à effectuer la somme des données de comptage qui sont divisées par un nombre entier d'une cadence d'échantillonnage en synchronisme avec la cadence d'échantillonnage, et envoie à un bloc de traitement de vitesse (36) les données de vitesse sous forme de données de vitesse les plus récentes, nécessaires pour le traitement à une cadence d'échantillonnage prédéterminée, ce qui permet de réduire au minimum les effets de l'élément de retard. Le processeur peut ainsi commander la vitesse avec toute la précision dont il est capable.

Title: Data encodement and reading method and apparatus.
Inventor: FINGER EUGENE P
IPC: G01R19/25
Filed: 1990-07-09
Abstract: A method and apparatus for measuring operations data which uses a commercially available digital multimeter (DMM) (310) as the data receiving and display device. Basic operations data is transduced to digital form and then coded with a width modulator. The width modulated data may represent total elapsed time or total counts of a measured operation. The full-scale range of the data is encoded as frequency. A technician reads the frequency of the data signal with the DMM (310) to determine the full-scale range of the data and then reads percent-of-range with the DMM (310) as duty cycle. For multiple operations data, peak voltage is used as a parameter identifier. Alternatively, the value of the parameter being measured, the full-scale range, and the parameter identifier may be encoded as any combination of frequency, peak voltage, or duty cycle.

Title: Microcontroller with fuse-emulating latches.
Inventor: BERMAN ERIC
IPC: G06F11/267
Filed: 1992-11-12
Abstract: A microcontroller fabricated on a semiconductor chip has an on-chip EPROM program memory with programmable EPROM configuration fuses located in a limited number of addresses of the on-chip program memory, the condition of each of EPROM fuse being defined as blown or not blown according to the value of the bit stored in the respective address of the on-chip program memory. The operating modes of the microcontroller are configurable by appropriately programming at least some of the EPROM fuses. Testing of the microcontroller in at least some of the operating modes is achieved by using latches outside the program memory to emulate the EPROM fuses, while suppressing the capability to set the condition of the EPROM fuses during the testing. Upon completion of the testing, control of the operating modes of the microcontroller is returned to the EPROM fuses, and the latches are precluded from further emulating the EPROM fuses.

Date Dec. 8, 1994The present invention relates to eutectic alloy systems, such as white irons, in which a primary phase grows out of the melt when the melt is cooled below the liquidus temperature and comprises pouring the molten metal alloy at a temperature at or above the liquidus in a stream into a casting mould to form a casting and introducing a particulate material into the stream of molten metal to extract heat from the molten metal alloy to undercool the molten metal alloy from the pour temperature into the primary phase solidification range between the liquidus and the solidus temperatures of the alloy and thereby initiate primary phase nucleation and restrict primary phase growth. The primary function of the particulate material is to act as a heat sink but the particulate material may at least partially dissolve in the melt and may act as a seeding agent for the primary phase. The invention is described with particular reference to high chromium hypereutectic white irons.
