Title: Transport carriage for an external fixator
Inventor: ALLARD RANDALL N
IPC: A61B17/66
Filed: 1996-11-26
Abstract: The transport carrier of this invention is configured for use with an external fixator having a hexagonal rod. The carrier includes a threaded sleeve which accommodates the hexagonal rod of the fixator. A compressible ball collet and retaining nut are carried by the sleeve and serve to lock the sleeve into position on the rod in a known manner. A clamp is carried by the sleeve and rotationally fixed relative to the rod by a key and key way, yet may shift along the sleeve. The clamp is configured to connect to one or more bone pins using a ball collet and retaining nut to fix the clamp to the pin. The bone pins connect to a bone fragment such that as the clamp shifts along the sleeve, the bone fragment is transported between two portions of a bone. An internally threaded sleeve is carried by the externally threaded sleeve and engages the clamp. Upon rotation of the internally threaded sleeve, the clamp and externally threaded sleeve move longitudinally along the sleeve.

Title: Electrospray and atmospheric pressure chemical ionization mass spectrometer and ion source
Inventor: BAJIC STEVAN
IPC: H01J49/26
Filed: 1996-12-13
Abstract: The invention comprises Atmospheric Pressure Chemical Ionization (APCI) and electrospray ionization sources for the mass spectrometric analysis of solutions, and associated methods.  The apparatus and methods are characterised in that ions generated by APCI or electrospray are directed such that their directions of travel immediately on formation can be resolved into two perpendicular components, one of which is aligned with a linear first trajectory which passes through an entrance orifice, an extraction chamber and into an evacuation port through which the extraction chamber is evacuated. The direction of travel is such that the component of velocity so aligned is smaller than the component perpendicular to it.  Ions leave the chamber along a second trajectory which is inclined at an angle between 30 and 150° to the linear first trajectory and may pass into a mass analyzer.  The invention provides improved sensitivity and a lower noise level in comparison with prior apparatus and methods using APCI and electrospray ionization sources.
Patent CA-2195909-A1 (CA)
Inventor: SMITH ARTHUR RAMSDEN
IPC: F02C6/10
Filed: 1997-01-24
Abstract: A high pressure combustion turbine is integrated with a double column cryogenic air separation system by cooling and purifying a portion of the compressed air from the combustion turbine compressor, work expanding a first portion of the resulting cooled air, and introducing the expanded air into the low pressure column. A second portion of the resulting cooled air is further cooled, throttled, and introduced into the high pressure column. A nitrogen product stream is returned to the turbine combustor, and a portion of the nitrogen product stream optionally is cooled, throttled, and recycled into the high pressure column. Preferably the higher pressure column operates at an absolute pressure which is about 20% to about 85% of the absolute pressure of the compressed air from the combustion turbine air compressor. Optionally an oxygen-rich liquid or a nitrogen-rich liquid is withdrawn from the higher pressure column during a period of low nitrogen product demand, stored, and withdrawn from storage to supplement feed to the lower pressure column during periods of high nitrogen product demand. Alternatively, high purity liquid oxygen is withdrawn from the lower pressure column during a period of low oxygen product, stored, and withdrawn from storage during periods of high oxygen product demand to supplement oxygen product withdrawn from the higher pressure column.

Title: A method to adapt synchronous transmission
Inventor: KERBERG DAG E SON
IPC: H04B7/26
Filed: 1995-09-07
Abstract: A method of adapting synchronous transmission to the rules that apply to asynchronous transmission in a radio medium. In asynchronous transmission, it is decreed that the transmitter/receiver operates in monitoring mode for a given short period of time (tm), in order to establish whether or not transmission shall take place. The synchronous transmission is, for instance, a TDMA transmission for a personal telephone system active over short distances (10 -- 200 m). According to the proposed method, the radio medium is monitored by a synchronous transmitter (PT) over a brief time period (G) between two time slots (T1, T2) and the power (Pm) received is measured and compared with a given prescribed threshold power (Pt) in accordance with asynchronous rules. Permission to transmit can be given on the basis of the results of this comparison.

Pendant le test, l'amplitude (Un) des impulsions de tension est accrue progressivement d'une valeur initiale à une valeur finale. Les deux valeurs prédéterminées (Un1, Un2) sont déterminées en fonction de l'occurrence d'une inversion de signe dans la différence entre les valeurs successives d'un paramètre qui représente une propriété d'un écart (5) entre l'électrode (6) et la pièce (2). Le paramètre peut être l'amplitude (Umin) d'un minimum global de la tension aux bornes de l'écart (5) pendant les impulsions de courant, minimum global produit par un mouvement oscillatoire de la pièce (2) et de l'électrode (6) l'une par rapport à l'autre. Le paramètre peut aussi être l'intégrale (Qn) du courant aux bornes de l'écart (5) pendant les impulsions de tension; ou l'intégrale (Fp) de la tension aux bornes de l'écart (5) pendant les impulsions de courant; ou la résistance aux borne de l'écart (5); ou la taille (St) de l'écart (5).

Title: Arc fault detection apparatus and circuit breaker incorporating same
Inventor: SCHLOTTERER JOHN CARL
IPC: H02H1/00
Filed: 1997-08-01
Abstract: Arcing-faults in an electric power distribution system are detected by a circuit which includes a band-pass filter generating a low frequency bandwidth limited arcing current signal having a bandwidth above the measurable harmonics of the ac current but below the frequency band of power line communications systems, about 3 KHz to 20 KHz and preferably about 6 KHz to 12 KHz. For each cycle of the ac current that this low frequency bandwidth limited arcing current exceeds a threshold, preferably related to the amplitude of the ac current, for a selected duration of the cycle, a fixed pulse is generated. If a time attenuated accumulation of these fixed pulses reaches a selected level representative of a number of closely spaced cycles in which the arcing current has been detected for the selected duration, an arc indicative signal is output. Preferably, the value of the time attenuated accumulation of pulses at which the arc indicative signal is generated is variable so that fewer pulses are needed to generate the output as the amplitude of the ac current increases.

Patent CA-2217693-A1 (CA)
Title: Transcoder with prevention of tandem coding of speech
Inventor: LEHTIMAEKI MATTI
IPC: H04W4/18
Filed: 1996-04-11
Abstract: The invention relates to a transcoder (TRCU1, TRCU2) having means for preventing tandem coding of speech in a mobile to mobile (MS1, MS2) call within a mobile communication system which employs a speech coding method for reducing transmission rate on the radio path. The transcoder (TRCU1, TRCU2) comprises a speech coder (52, 73) which encodes the speech signal into speech parameters for transmission to a mobile station, and decodes the speech parameters received from the mobile station into a speech signal according to said speech coding method, as well as a PCM coder (54, 72) for transmitting an uplink speech signal to and for receiving a downlink speech signal from a PCM interface in the form of PCM speech samples. In addition to the normal operation, the transcoder transmits and receives speech parameters through a PCM interface in a subchannel formed by least significant bits of the PCM speech samples. Thus, it is possible to prevent tandem coding but at the same time maintain the standard PCM interface and the signalling and services associated thereto.
