Patent EP-0336453-B1 (EP)
Inventor: ADAMS ROGER WILLIAM
IPC: B02C23/06
Filed: 1986-07-17
Granted: 1993-12-22
Abstract: Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor. During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber. Pulses of gas are directed periodically at the material through inlets (15) to prevent agglomeration of the material. The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8). Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.

Abstract: In a radio-frequency receiver with a device for indicating the transmitter names, transmitters are also to be indicated which do not radiate any additional signals containing the identification data. For this reason, tables in which each transmitter site is assigned the associated frequency, the transmitter name and a list of those transmitters which can be received at this transmitter site are stored in a digital memory. Furthermore, there is a microprocessor which - tunes the receiver to a strong transmitter radiating additional signals containing the identification data (RDS transmitter) and determines its frequency and its name, - determines from a first and from a second table the transmitter site belonging to the frequency and the name of this RDS transmitter, - determines from a third table all sites assigned to the site of this RDS transmitter, - finds from the first table among these sites the site of which the associated frequency corresponds to that of the unknown transmitter, and -determines from the second table the name belonging to this site and supplies it to the display device.

Granted: 1993-04-14
Abstract: Process and arrangement for the control of an electrically controlled brake circuit of a multi-circuit brake system with pressure-actuated brakes. 
<??>2.1 A known process and a known arrangement require in each brake circuit a brake pressure modulator which can be actuated both electrically and by pressure. This means a considerable outlay. 
<??>2.2 In order to reduce this outlay, the invention proposes to convert the pressure modulated by a brake value transmitter (15) into an electrical signal the dependent on the level of said pressure and to control the electrically controlled brake circuit (II), alone or together with other systems, by means of this signal. 
<??>2.3 The preferred field of application of the invention is motor vehicle brake systems with pressure-actuated brakes in which the brake pressure in at least one brake circuit is electrically controlled.

Title: Wild-flow loss-in-weight weighing system
IPC: G01G13/28
Filed: 1989-02-15
Granted: 1992-09-16
Abstract: The present invention relates to a continuous weighing system and more specifically to a novel combination of a ''wild-flow'' flow of material and a loss-in-weight monitoring system, whereby an uncontrolled flow of material from a wild-flow stream is accurately weighed by the loss-in-weight system. The system has a surge hopper (25) receiving material from the ''wild-flow'' source (10) and discharging into a loss in weight feeding system hopper (40). The rate of output of the material the loss in weight system discharges from its output (55) is adjusted in accordance with the flow of material into the surge hopper (25) from the flow source (10, 15) over a predetermined period of time.

Abstract: A payer party obtains from a signer party by a blind signature system a first public key digital signature having a first value in a withdrawal transaction; the payer reduces the value of the first signature obtained from the first value to a second value and provides this reduced-value form of the signature to the signer in a payment transaction; the signer returns a second digital signature to the payer by a blind signature system in online consummation of the payment transaction; the paper derives from the first and the second signature a third signature having a value increased corresponding to the magnitude of the difference between the first and the second values. Furthermore, the following additional features are provided: payments are unlinkable to withdrawals; a shop between the payer and signer can be kept from obtaining more value than desired by the payer; the first value need not be revealed to the signer or intermediary in the payment transaction; the returned difference can be accumulated across multiple payment transactions; and the returned difference can be divided between a plurality of payment transactions.

Abstract: A high-pressure control valve (2) used in chromatography serves as a counter pressure control valve which, in a separating column, is intended to maintain a specific predeterminable pressure. The valve has a valve seat (12) with an outlet channel opening (18) located in its center and a valve body (13) that cooperates with the valve seat. The valve body (13) can be moved with the aid of a piezo transducer, actively in the opening direction and, while being monitored, actively in the closing direction. The opposed faces of the valve seat (12) and the valve body (13) are so shaped that an annular gap (16) that widens radially towards the outside starting from the opening (18) of the outlet channel is produced. When the valve is in the closed position, this results in the formation of a narrow sealing zone directly at the edge of the opening of the outlet channel.

Title: Interactive language learning system
Inventor: WILLETTS JOHN A
IPC: G09B19/06
Filed: 1990-01-26
Granted: 1995-09-27
Abstract: An interactive computer assisted language learning system which allows a student to select a model phrase from text displayed on an electronic display; record (in digitized form) his own pronunciation of that phrase; and instantly listen to the digitized vocal version of the selected phrase and his own recorded pronunciation for comparison purposes. An audio CLIP mode permits the student to select any (random) portion of displayed text (e.g., a phrase, a small part of a phrase, a single word, a syllable, or a phoneme) using cursor control or the like and to control the system to play the voice corresponding to that selected portion. A SoundSort text reconstruction exercise based on aural clues automatically randomizes the order of plural phrases, provides digitized utterances of the phrases in the randomized order, and requires the student to reconstruct the original order using a visual display interface. Integration of digitized sound in a high-level authoring system (as distinct from an authoring language) is provided. An easy-to-use "WYSIWYG" ("What you see is what you get") user interface reduces or eliminates user mistakes and associated frustration and does not require the user to have any programming ability. An extremely flexible authoring system allows a teacher to link recorded digitized sound with customized on-screen text (which may but need not match the digitized sound). This allows a wide variety of free-form exercises to be created.

Abstract: An anticoagulant composition containing an effective amount of factor Xa having the active serine site inactivated that functions rapidly and effectively in vivo to suppress coagulation. In a preferred embodiment, Factor Xa, a serine esterase that forms a complex with Factor Va, Ca++, and phospholipid to catalyze prothrombin activation, is first inactivated with an active site inhibitor, such as dansyl-glu- gly-arg-chloromethyl ketone, to form inactivated factor Xa. In another embodiment, Factor Xa is expressed from a gene sequence wherein the portion encoding the active serine region is modified. The inactivated protein retains the ability to bind to endogenous factor Va in vivo, and has a half-life of approximately ten hours. Administration of inactive factor Xa to the blood of a patient results in the formation of inactive factor Xa-Va complexes in vivo, thereby inhibiting coagulation.
