Abstract: A lock assembly for locking and unlocking a door comprising a lock bar moveable between a locked and unlocked position, three locks, each of which have lock arms moveable between a locked and an unlocked position, and a linkage connecting the lock arms to the lock bar. The linkage has a first operating configuration whereby the lock bar moves from its locked to its unlocked position in response to the movement of any pair of lock arms from their locked to their unlocked position. The linkage also has a second operating configuration whereby the lock bar moves from its locked to its unlocked position in response to either movement by a predetermined pair of lock arms from their locked to unlocked position or the movement of the third lock arm from its locked to unlocked position.

Granted: 2007-04-10
Abstract: A multiple sensor smoke detector includes at least an ionization and a photoelectric sensor. Outputs from the sensors are fed to circuitry for generating continuously variable coefficients. One coefficient corresponds to each sensor output. Respective coefficients and sensor outputs are multiplied in multiplier circuitry to produce processed outputs. The processed outputs are combined in a summing circuit to produce at least one output value indicative of a level of detected smoke. The coefficient generating circuitry, the multiplier circuitry and the combining circuitry could be implemented in a programmed microprocessor. The coefficient generating circuitry could be implemented using prestored membership functions indicative of various types of fires.

Abstract: A methodology for allocation of transmission capacity in communications networks is provided wherein a collection of constant rate channels is implemented between end points in the network. In that methodology, periodic sources are assigned channels of bandwidth corresponding to the transmission rate for each such source, and bursty sources are assigned to channels providing bandwidth corresponding to a minimum service guarantee for each such bursty source. Channel capacity assigned to periodic services which is not needed by such sources is then made available to bursty sources for accommodating capacity requirements of such bursty sources over and above the minimum service guarantee.

Abstract: Reflective aluminum trim for use in automobiles, trucks, boats and a variety of household and industrial appliances is produced by forming aluminum strip into a desired shape, followed by selective application of a protective coating to the show surface of the shaped strip. The resultant trim piece includes a highly reflective aluminum show surface covered with the protective coating having a high distinctness of reflected image.  In a preferred embodiment, a portion of the shaped aluminum strip is covered with a thermoplastic such as vinyl.  The thermoplastic is preferably co-extruded onto the shaped aluminum strip using an adhesive to bond the thermoplastic directly to an un-coated portion of the aluminum surface. Prior to application of the thermoplastic, a single heating step may be used to cure both the protective coating and the adhesive.

Abstract: A  dragline  bucket  transporter  for  use  in  moving  a dragline  bucket  with  a  hauling  vehicle  comprises  a  wheeled trailer having a U-shaped frame with tire-supported free ends, the free ends forming-an open end.  The frame is moved by a hauling vehicle to surround the sidewalls of a dragline bucket.          Once  the bucket  is  surrounded,  a  cross member  of  the  frame engages and lifts a front end portion of the bucket by action of a hitching assembly attached to the hauling vehicle.   With the front end of the bucket elevated, lifting assemblies located at the free ends of the frame lift up a rear portion of the bucket so that it is off the ground.   The hauling vehicle can then transport  the  bucket  to a desired location,  the bucket  then removed from the transporter for use with a dragline.

Abstract: La présente invention concerne un récipient réalisé de telle façon que l'aspiration et le relâchement de toute la quantité d'un échantillon et d'un réactif en provenant puissent être faits sans fermer l'extrémité avant d'un tube d'aspiration et d'écoulement de liquide. Le récipient est conçu pour des opérations sûres de distribution et d'agitation par un distributeur et, plus particulièrement, pour aspirer la totalité de l'échantillon et du réactif se trouvant dans le récipient. Etant donné que toute la quantité est traitée comme une quantité fixe, sans que l'on ait besoin d'un excès d'échantillon ou de réactif, on peut obtenir un récipient d'une conception simple, qui convient pour un examen de haute précision de la totalité de l'échantillon et du réactif. Ce récipient comporte, au fond de la partie intérieure du corps de récipient, un creux dont la largeur est inférieure au diamètre d'une partie avant d'un tube d'aspiration et d'écoulement de liquides qui est introduite dans le récipient et en est retirée. Même quand cette partie du tube est introduite dans la partie intérieure inférieure, c'est sensiblement la totalité du liquide se trouvant dans le récipient qui est aspirée depuis la partie avant du tube, en raison de la présence du creux. Le liquide aspiré est ensuite relâché et réparti uniformément. Cela permet une réaction uniforme entre l'échantillon et le réactif.

Patent CA-2244086-C (CA)

IPC: B64D15/20

Granted: 2005-11-01
Abstract: This invention, called "Distributed Fiberoptic Ice Detector", (DFOID) detects an early formation of ice at multiple, distributed locations on surfaces it is attached to. DFOID may be thought of as a generalization of FOID (fiberoptic ice detector), an earlier patent (application CIPO# 2,048,991) by the same inventor. While FOID accomplishes ice detection at either (i) single or (ii) multiple (distributed) locations, DFOID is intended for the latter task such that the response from the individual, distributed detection-locations is equalized. Alternatively, instead of equalization, conformity to a pre-specified rule describing how the response should vary from one to another location may be achieved. Just like FOID, DFOID is also based on the light diffusion by ice and light reflection from ice boundaries that optically couple multimode optical fibres in specially built sensitive zones distributed along the fibre. A most widespread use of this invention is expected in the aircraft industry for remote detection of ice formation around critical parts - wings (and hinges of command surfaces in particular).

Title: A method and apparatus for enhancing communication reception at a wireless communication terminal
Inventor: GREENSTEIN LAWRENCE JOEL
IPC: H04L27/26
Filed: 1998-08-18
Granted: 2002-10-15
Abstract: A system provides transmit diversity with feedback to enhance the reception of communication signals at a wireless communication terminal.  Multiple antennae are provided at the base station.  The multiple antennae transmit multi-carrier information signals such as OFDM including pilot tones.  The wireless communication terminal receives the pilot tones and performs processing on those tones to detect the relationship between the information signals transmitted from the various antennae of the base station.  A feedback signal, based on the comparison of the pilot tones communicates back to the base station information about the channels of the respective transmit antennae to the terminals.  The base station modifies the transmission processing associated with the various transmit antennae based upon the feedback signal.  The modified processing improves the reception of the information signals at the wireless communication terminal.
