Abstract: An improved multi-component mixing and dispensing apparatus having a replaceable nozzle (16) associated therewith in which plural components are mixed before dispensing thereof. The apparatus includes improved component feed systems to maintain each component to be mixed and dispensed in a segregated condition until mixing is desired. The component feed systems include internal passages (40, 42) within the apparatus and selectively actuated valves (84) which are operable to allow flow of a component to an outlet port (44) formed in the apparatus. A mixing and dispensing nozzle (16) may be coupled into the apparatus so as to communicate with the outlet ports (44) of the component feed systems. The component feed systems include self-cleaning structures to ensure that the internal passages remain unblocked, and the apparatus further includes structure (97) to selectively render the apparatus non-operational when desired. A replaceable mixing and dispensing assembly (100) is disclosed, which allows more thorough metering and mixing of plural components within a kinetic mixing chamber (112), and may include a second stage (120) of mixing if desired.

Abstract: Programme d'application logicielle assurant le raccordement d'un numéro d'annuaire pour tous les appels d'arrivée dirigés vers ce numéro d'annuaire et déterminant toutes les opérations à effectuer relativement à une unité mobile et à un poste téléphonique.  Ce programme d'application logicielle dirige ensuite les appels d'arrivée vers l'unité mobile et le poste téléphonique indépendamment du lieu de connexion de ces unités avec un système de télécommunication.  Un appel de départ effectué à partir de cette unité mobile ou de ce poste téléphonique est commuté vers le programme d'application logicielle comme si cet appel de départ provenait de l'emplacement où se trouve ce programme.  De même, le numéro d'annuaire de départ utilisé pour effectuer un appel de départ est le numéro d'annuaire associé au programme d'application logicielle.  On utilise deux systèmes de numéro de sélection : le système du numéro d'annuaire constitué de numéros de téléphone classiques et un système de sélection secondaire.  Ce dernier est mis à contribution par le programme d'application logicielle pour diriger et recevoir des appels de l'unité mobile et du poste téléphonique.

Abstract: The operation of a steam sterilizer (200) is monitored by a test unit (100) and a controller which together comprise a system which can be operated in two principal method schemes: (1) the testing for completeness of air removal from a sterilizer chamber (202), and (2) the testing for effective sterilization conditions. These methods each have two principal modes of operation: (a) the performance of a Bowie and Dick type test, as is usually done on a once-a-day basis; and (b) monitoring the sterilizer (200) during load conditions. In a preferred embodiment a test unit (100) including temperature (122) and pressure sensors (124), a moisture sensor (126) and a heat sink (112) are positioned within the chamber (100) of a steam sterilizer (200) and transmit by radio (120) the conditions therein to an external controller (150). The test unit (100) can employ a replaceable cartridge (110) to assure effective operation even after a large number of cycles of operation.
Patent CA-2137295-A1 (CA)
Inventor: SLICKER JAMES M
IPC: F16D28/00
Filed: 1994-12-05
Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor and a transmission input speed sensor and develops a clutch actuation signal controlling a clutch actuator from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach engine speed employing,an approximate inverse model of this oscillatory response.      The automatic clutch controller preferably includes a slip integral function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a prefilter and a compensator constructed to reduce the need for detailed particularization for individual vehicles or vehicle models. A lag compensation function in the compensator adds robustness to the system by increasing low frequency gain. A freeze function suspends operation of the slip integral , the prefilter and the compensator during engine deceleration or when throttle position is high and engine speed is low, to moderate or stop clutch advance to prevent engine overloading.

Filed: 1995-09-28
Abstract: In an asynchronous transfer mode (ATM) system, interleaved cells are formed at the transmit end by combining into each interleaved cell certain bits from each of plural different original ATM cells, the interleaved cells are transmitted over the communications link, and then deinterleaved at the receive end. Any bursty errors occurring on the communications link will, after deinterleaving, be spread out over multiple original ATM cells, maximizing the error correction for ATM cells and error detection for AAL capability and minimizing loss of data. The C1 byte in the Physical Layer Convergence Protocol (PLCP), which indicates the location of end of the PLCP frame, is protected against the burst errors by replication of C1 byte through inserting them in the growth bytes Z1 through Z4.

Title: Method for i.a. measuring the thickness of plate construction and pipes
Inventor: WAAG TOR INGE
IPC: G01S15/88
Filed: 1994-03-17
Abstract: It is described a method for automatic state control, inspection, cleaning and/or surface treatment of structures, especially measuring the thickness of plate constructions and pipes by means of ultrasound signals from a self propelled, remotely controllable unit (1). The self propelled unit (1) is continuously moved in the measurement area, and a transmitter (6) transmits an ultrasound signal in a direction substantially perpendicular to the surface of the construction. A reflected signal is received by a receiver (6), determining thickness and material quality of the construction at the measurement spot, on the basis of received reflected signal, and parameters such as transit time for the reflected signal. The self-propelled unit (1) performs self-positioning by means of previously known spots on the construction. All received data regarding waveform of the reflected signal is stored in a computer, and thickness and material quality are verified by comparing data for received signal in one spot, with data for received signals in adjacent spots. The steps are repeated for collection of data for new measurement spots.
