Title: Power converter for an electrically-compensated constant speed drive.
Inventor: DISHNER BRYAN W
IPC: H02M5/27
Filed: 1986-12-10
Abstract: Electrically-compensated constant speed drive, CSD, (10) which includes a speed summer (18) having first and second input shafts (20, 36) and one output shaft (22). The first input shaft (20) is coupled to a variable speed prime mover (16) and the output shaft (22) develops a constant speed motive power.

Title: Particle analyzer for measuring the resistance and reactance of a particle.
Inventor: COULTER WALLACE H
IPC: G01N27/00
Filed: 1987-10-20
Abstract: A circuit (10) provides data needed to measure the electrical opacity of a particle (20), such as a blood cell passing through a Coulter type transducer (12). The circuit (10) includes a current source (22) for providing a conventional d.c. current through the sensing aperture (16) of the transducer (12), and an oscillator (24) for providing a high frequency current through the aperture (16). The oscillator (24) includes an active device (32) and a resonant circuit (34), and the aperture (16) is coupled in parallel with the resonant circuit (34). As a particle (20) passes through the aperture (16), the resistance of the aperture (16) increases, which increases the Q of the oscillator (24), whereby the oscillator (24) output signal (Fig. 3) is amplitude modulated in accordance with the increased Q. Multiple oscillators (F1, F2 ... FN) of different frequencies can be coupled in parallel with the transducer (12) through a coupling cirucit (54, 77 and 79), which connects each oscillator (F1, F2 ... FN) through a low impedance path and isolates each oscillater (F1, F2 ... FN) from signals having frequencies of the other oscillators.

Filed: 1989-03-04
Abstract: On décrit un polymère oléfinique possédant un poids moléculaire compris entre 500 et 50000 et présentant des groupes d'anhydride acide uniquement dans ses terminaisons, et une résine contenant ce polymère. Lorsqu'on le mélange à un polyamide, ledit polymère oléfinique forme une résine présentant une résistance considérablement meilleure, notamment une meilleure résistance à la traction. Lorsque ledit polymère oléfinique (composant (A)) est combiné à un polyamide (composant (B)) et à un polymère oléfinique autre que le composant (A) pour préparer un composé ternaire, le composant (A) sert d'agent de compatibilité pour les composants (B) et (C) pour améliorer l'efficacité de la dispersion du composant (C) dans le composant (B), ou du composant (B) dans le composant (C). On obtient ainsi une résine présentant une résistance visiblement meilleure (résistance aux chocs ou à la traction), une meilleure résistance LLC et une faible capacité d'absorption d'eau.

Title: Pneumatic wheel chair cushion for reducing ischemic injury
Inventor: HOLDREDGE TERRY KEENE
IPC: A61G7/057
Filed: 1993-03-11
Abstract: A pneumatic cushion (A) for a wheel chair and the like is disclosed which comprises an air housing box (B), a plurality of air openings in the air housing box, and a plurality of air channels (16, 18, 20, 22) communicating with an air supply. The air channels communicate with the air openings to deflate and inflate individual air sacks (S) carried over the air openings. An air distribution manifold (F) includes a rotating blocking member to periodically block air distribution to the air sacks allowing them to deflate. The air sacks (S) are constructed from a fabric having a low air permeability thus allowing air to escape (70) through the sacks for deflation which cools the portion of the occupant seated on the cushion while allowing temporary pressure relief during deflation. The air sack inflation system is open so that pressure may be relieved by a backward flow of air (72) through the system.

Title: Verifying secret keys in a public-key cryptosystem.
Inventor: MICALI SILVIO
IPC: G06Q20/00
Filed: 1993-04-20
Abstract: A method, using a public-key cryptosystem, for enabling a predetermined entity to monitor communications of users [suspected of unlawful activities while protecting the privacy of law-abiding users], wherein each user is assigned a pair of matching secret and public keys. According to the method, each user's secret key is broken into shares. Then, each user provides a plurality of "trustees" pieces of information. The pieces of information provided to each trustee enable that trustee to verify that such information includes a "share" of a secret key of some given public key. Each trustee can verify that the pieces of information provided include a share of the secret key without interaction with any other trustee or by sending messages to the user. Upon a predetermined request or condition, e.g., a court order authorizing the entity to monitor the communications of a user [suspected of unlawful activity], the trustees reveal to the entity the shares of the secret key of such user. This enables the entity to reconstruct the secret key and monitor the [suspect] user's communications.

Title: Inflatable pump and article.
Inventor: POMEROY PAUL E
IPC: F04B43/08
Filed: 1993-07-06
Abstract: The disclosure relates to a collapsible flexible pump (10) which includes an inflatable spring framework (12). The inflatable spring framework is formed by attaching a layer of flexible material over selected exterior portions of the flexible material pumping chamber to form a passageway therebetween. Inflation of the inflatable spring framework via an inflation valve (28), results in the collapsed flexible pump distending into a three dimensional pumping chamber inscribed by the inflated spring framework. The pumping chamber includes appropriate inlet and discharge valves (32, 30). By applying a compressive force to the pumping chamber, the volume of fluid within the pumping chamber is forced out through the discharge valve. The restoring tendency of the distended inflatable spring framework returns the pump chamber to the extended position on the returning intake stroke. A plurality of exemplary inflatable articles is disclosed.
