Patent CA-2060289-C (CA)
Title: Antiplaque oral compositions
Inventor: GAFFAR ABDUL
IPC: A61K8/00
Filed: 1992-01-29
Granted: 2002-09-03
Abstract: An antiplaque oral composition, such as a toothpaste, gel dentifrice, tooth powder, mouthrinse or mouthwash, tooth hardener, anticalculus composition, gum or lozenge, comprises triclosan as an antiplaque component, the antiplaque action of which is unexpectedly and beneficially increased by the presence in the oral composition of a phenolic flavoring agent, such as eucalpytol, thymol, methyl salicylate, menthol, phenol, halogenated derivatives thereof, and mixtures thereof. Preferred such compo-sitions are toothpastes, gel dentifrices and mouthrinses or mouth-washes. Also within the invention are processes of repeatedly applying such antiplaque oral compositions to the teeth to obtain the antiplaque benefits mentioned.
Patent CA-2060810-C (CA)
Title: Target mounting system
Inventor: GRANT ROBERT P
IPC: F41J1/01
Filed: 1992-02-07
Granted: 1994-09-13
Abstract: The system is for use on outdoor firing ranges. Target cards bearing the printed targets are secured to a 4ft square panel made of Coroplast (trademark), which is extruded twin-walled polypropylene sheet. The sheet is formed with built-in curvature, which is sufficient to render the target panel rigid, even though the material is thin enough that bullets can pass through without punching-out. Because of the curvature, no frame is required to keep the panel rigid. Scoring rings are printed on the face of the panel, together with markings that allow an attendant to align fresh target cards with the scoring rings. Two, or three, plies of Coroplast may be welded/glued face to face, for larger targets.

Title: Voice messaging system with voice activated prompt interrupt
Inventor: JOHNSON MARK ALAN
IPC: H04Q11/04
Filed: 1992-03-06
Granted: 1996-01-09
Abstract: An arrangement providing voice activated prompt interrupt for a voice messaging system. The exemplary apparatus includes a telephone line interface, amemory device, a processor, a prompting device and a recording device. Once a call is established at the interface, the processor causes the prompt to be played and simultaneously the incoming signal to be sampled. An echo estimate is determined, subtracted from the incoming signal and a determination is made if incoming speech is detected. If incoming speech is detected, the prompt is stopped and the buffered incoming signal is directed to the recording device.

Title: Methods for rapid microbial detection
Inventor: REES CATHERINE ELIZABETH DUNN
IPC: C12Q1/04
Filed: 1991-08-08
Granted: 2003-10-14
Abstract: A method of testing for target bacteria involves adding bacteriophage to a sample to infect the bacteria in the sample; kill-ing extracellular bacteriophage without at the same time killing phage-infected bacteria; amplifying bacteriophage remaining in the sample; and causing the bacteriophage to infect reporter bacteria and thereby produce an observable signal. The reporter bac-teria are genetically engineered to have an indicator gene which on expression gives rise to a detectable signal, wherein expression of the indicator gene is initiated on bacteriophage infection of the bacteria.

Abstract: The present invention relates to a drill bit (10) for rock drilling, pref-erably a down-the-hole drill bit, said drill bit (10) including a head (11) and a shaft (12), said head (11) defining a cutting face (14) that carries a num-ber of hard material button inserts (l5) having end portions extending out-wardly of said cutting face (14), means (16, 17) for transporting flushing medium from the free end (13) of the shaft (12) to the cutting face (14) of the head (11), said means for transporting flushing medium including a central passage (16) extending from the free end (13) of the shaft (12) and terminating in the head (11) short of the cutting face (14) and at least one branch passage (17) emanating from the central passage (16) and emerging in the cutting face (14). In the filed of down-the-hole drill bits big volumes of flushing medium, normally compressed air, are used since the flushing medium is also activating the down-the-hole hammer. Those big volumes provide erosion of the cutting face since the flushing medium has a very high speed when passing the front face of the drill bit. Said erosion creates problems when so much material, usually steel, of the cutting face has been eroded away that the button inserts are lost before they are worn out. The idea of the present invention is to decrease the velocity of the flushing me-dium before reaching the cutting face (14) of the drill bit (10). This is done by increasing the cross-sectional area of the branch passage (17) along a certain length (L) of said branch passage (17).
