Patent CA-2093537-A1 (CA)
Inventor: EKLUND SIGURD T
IPC: E05B13/08
Filed: 1993-04-08
Abstract: A door security system is used in conjunction with a lock such as a deadbolt lock having an "inside" located actu-ating handle, of the type used in hotel rooms, having a major and a minor dimensional axis. The security device has a base-plate that fits beneath the faceplate of the lock and which can be oriented during installation in relation to the shaped actuating handle of the lock. The baseplate of the security device extends eccentrically off center and supports a pivot post that carries a latch locking plate. The locking plate is pivotally supported on the pivot post, for pivotal rotation thereabout, and has an arcuate passage-off-set from the pivot post, in use to receive the lock actuating handle. In use, with the baseplate installed beneath the faceplate of the lock and the lock handle rotated to extend the bolt, the locking plate may be rotated about the pivot post, swinging the arcu-ate passage over the lock handle in immobilizing relation therewith. In this condition the shaped lock handle cannot be rotated, and the lock is restrained in a locked condition de-spite the use of a proper key, externally.

Title: Vacuum hose storage and access apparatus for a central vacuum cleaning system
Inventor: WORKHOVEN GARRY
IPC: A47L9/00
Filed: 1993-04-08
Abstract: ABSTRACT OF THE DISCLOSURE A vacuum hose storage and access apparatus for a central vacuum cleaning system is described, which includes a power unit. A 12 volt direct current retraction motor powered by the power unit is mounted on a base and has an output shaft.  A gear reduction unit is provided having an input shaft and an output shaft.  The input shaft is rotatably coupled to the output shaft of the motor.  A clutch is disposed between the output shaft of the gear reduction unit and a vacuum hose reel. The clutch has an engaged position and a disengaged position. In the disengaged positioned the reel is freely rotatable thereby enabling vacuum hose to be freely pulled from the reel. In the engaged position the reel is indirectly coupled through the gear reduction unit to the output shaft of the motor such that upon rotation of the output shaft of the motor the output shaft of the gear reduction unit rotates the reel at a reduced rate of rotations per minute in a direction which retracts the vacuum hose back onto the reel.

Title: Telecommunications device and related method
Inventor: RICHARD DANIEL D
IPC: G06Q40/00
Filed: 1991-10-16
Abstract: A telecommunications system includes a method for at least partially automatically converting monetary amounts in a document from one currency to a second currency. In addition, the telecommunications system includes a method for at least partially automatically translating a document being input in one natural language at a transmitting machine such as a facsimile or telecopier to a second natural language to be displayed, printed or otherwise communicated at a receiving end of a telecommunications link. A  document containing the monetary amounts or translated portions is transmitted from a transmitting machine (40) and displayed, printed or otherwise communicated at a receiving end (36) of a telecommunication link. The monetary conversion and/or language translation may occur at any point in the telecommunications system, particularly at a transmitting facsimile device, a receiving facsimile device or a central facility operatively connected to a telecommunication network (26). The monetary conversion is preferably accomplished fully automatically, with decoders being used for determining identities of input and output currencies.

Title: Auto release choker
Inventor: MCPHEE J BRENT
IPC: F16G11/14
Filed: 1994-02-24
Abstract: AUTO RELEASE CHOKER  ABSTRACT OF THE DISCLOSURE           A choker hook is connected to a choker cable and is used for pulling a log from its felled position to a desired location.  The choker hook is remotely released from the log without manual intervention at the desired end position.  The choker hook has a configuration where a ferrule on the end of the choker cable tends to nest within the choker hook and assume a locking position when the log is being transported. When the direction of pull in the cable is reversed, the forces will tend to remove the ferrule from its locking position and release it from the choker hook thereby releasing the log. During the force reversal, the choker hook rotates about a predetermined angle and about predetermined axes of rotation depending on its specific configuration.

Filed: 1992-09-02
Abstract: The invention concerns a package and a method for producing the package and aims at obviating the risk of infection from a possibly contaminated or leaking sample, as well as enabling inexpensive and simple production. This is essentially achieved by a package having two compartments (P, M) each sealable by means of a flap (H1, H2), the flaps (H1, H2) as well as the openings of the two compartments being located on opposite sides of the package. The use of a translucent material and of an absorber changing colour when contacted with the sample enables visual detection of leakage inside the sealed package.

Pour cette méthode, on utilise soit un élément chimique soit un composé organique comportant un ou plusieurs atomes qui sont des isotopes non radioactifs qu'on ne retrouve pas généralement dans la nature. Une petite quantité du composé isotopique est introduit avant l'expédition dans le récipient de stockage contenant le produit chimique à transporter.  l'arrivée au point de destination, un échantillon du produit chimique expédié est analysé. La correspondance entre le composé isotopique détecté dans le produit chimique et le composé isotopique introduit dans le récipient de stockage avec l'expédition constitue une indication à l'effet que le produit chimique expédié est identique au produit chimique reçu. Des matières non  radioactives peuvent aussi être utilisées pour détecter la source d'un contaminant nouvellement introduit dans une alimentation en eau. La substance chimique peut être un isotope non radioactif du produit chimique transporté.

Abstract: Disclosed is a method for the determination of urinary protein and creatinine in a single reaction vessel using a continuous process. The method involves adjusting the pH to a level suitable for carrying out an immuno assay for the protein and making such a determination by an immuno agglutination technique.      Raising the pH to a level suitable for determining the creatinine quickly dissipates the cloudiness caused by the agglutination reaction, so that the creatinine determination can be carried out without delay.

Title: Electromagnetically actuated reciprocating compressor driver
Inventor: STUART KEITH O
IPC: H02K33/10
Filed: 1994-01-31
Abstract: Compressor (50) has electromagnetic actuator (52) for driving the piston (58) in compression cylinder (56).  Electromagnetic element (76) has core (77) and coil (80).  The core has surface (104) and channel (90).  The coil is disposed in the channel.  Axially reciprocating armature element (78) is interconnected with the piston, defining an axial stroke having a stroke midpoint and stroke peak.  The armature element has surface (94) dimensioned to align with the electromagnet surface at the stroke peak.  Primary spring (84) disposed on one end of the armature element biases the armature from axial movement.  Secondary spring (86) disposed on the opposing end of the armature element biases the armature from movement in an opposite axial direction.  The springs bias the armature to resonate at a pre-determined frequency.  Applied current at stroke midpoint continues the resonating frequency, and allows the armture surface to overcome friction losses and compression forces.  Two actuators placed back-to-back creates a dual piston compressor.
