Patent CA-2024425-A1 (CA)
Inventor: GORTON LANNY A
IPC: A61M5/00
Filed: 1990-08-31
Abstract: An ultrasonic  air-in-line detection  system for use  in detecting air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed which automatically loads the outlet tubing at the bottom of the cassette into a slot in an ultrasonic sensor housing when the cassette is installed on the main pump unit.  The system uses a tubing adapter mounted on the outlet tube below the cassette, with the tubing adapter having a tapered top end. The tubing adapter interacts with a pair of ramps located on the bottom and front of the ultrasonic sensor housing around the slot to draw the tubing adapter into a recess located on the bottom of the ultrasonic sensor housing, thereby drawing the outlet tubing fully into the slot between an ultrasonic  transmitter  and  an  ultrasonic  receiver  in  the ultrasonic sensor housing when the cassette is installed.

Title: Centre drive automobile
Inventor: RASMUSSEN EVALD
IPC: B62D61/10
Filed: 1990-09-25
Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a centre drive car, having conventional steerable front wheels and rear wheels.  The centre drive has either roller or paired wheel traction. These are mounted on a swivel, which is directionally slave controlled by the conventional steering. A small motor, either directly linked via a differential, or more preferably via a hydraulic circuit including a differential, drives the central roller or wheels.  The swivel is preferably retractable, by a lifting device, which may be operator controlled, or speed controlled by a governor.  The centre drive can be used under limited speed conditions, in a vehicle for urban use, where it would be more economical than a conventional high speed engine.  It can also be used in a conventional vehicle under limited speed conditions, instead of the conventional engine.

IPC: G02B6/38
Filed: 1990-10-16
Abstract: A pair of interengageable connectors for interconnecting optical fiber tape or ribbon cables which have a plurality of parallel optical fibers within a relatively thin and wide covering.  Each connector has a ferrule formed by semi-cylindrical elements with engaging and axially extending planar faces.  One end of the elements is a coupling face, and the planar faces have grooves extending axially from the coupling face for receiving the fibers with the covering removed and a recess remote from the coupling face for receiving the fibers with the covering thereon.  The elements are held together by a sleeve which extends from at or adjacent the coupling face toward the other end of the ferrule.  A ring nut with teeth for engaging corresponding teeth of the other connector encircles the sleeve and the ferrule and is slidable axially with respect thereto.  A spring urges the ring nut toward the end of the ferrule remote from the coupling face.  The assembled elements have axially extending holes receiving alignment pins.

Title: Crawling and talking doll
Inventor: FERRI JAIME
IPC: A63H3/28
Filed: 1991-08-07
Abstract: The doll of the invention incorporates a mechanism and electric circuit that, originating from a general activa-tion motor which moves a series of engagements, brings about a correlative series of movements which cause the doll to crawl and give out a message and, subsequently, to stop crawling and raise the trunk of its body and head, to turn its head and give out a new message. These movements are based on the eccentric operating several elements related to the arms, legs and head. Likewise, the emission of the messages is based on parts which are independent but combined electrically and mechanically with the general mechanism in order that, altogether, they achieve a succesion of movements which are repeated constantly until a general switch is activated by means of, for example, a dummy, or by means of a ball switch activated automatically when the doll is picked up and put upright.

Title: Gripper clamp and machine for treating objects, particularly bottles equipped therewith
Inventor: PERRIER RENE
IPC: B08B9/20
Filed: 1991-04-10
Abstract: Jaws (38) can move between dripping and release positions.       The passage to the release position is controlled by a slide (42) under the action of a ramp (48) and via tenons (44) which are attached to the slide (42) and which slide in grooves (46). The reverse movement is controlled by the same parts under the action of a return spring which acts on the slide (42). The transmission of movement by the systems with tenons (44) and grooves is irreversible; so that the neck (2) of a bottle held between the jaws (48) cannot become dislodged: a force (F1) applied to the jaws (38) cannot move the slide to open the jaws (38). Used to obtain fast machines without increasing the clamping force on the treated objects (bottles).
