Abstract: ABSTRACT OF THE DISCLOSURE       A device for dispensing a predetermined quantity of the contents of a container.  The device includes a flexible container capable of being reversibly deformed by squeezing.          The container has a neck defining an opening for dispensing contents when it is in a predetermined orientation.  A chamber is mounted in the neck, and has a first end extending into the container and a second end aligned near the opening.  A dispenser is mounted inside the chamber and includes a piston for leading flow of contents.  The piston is sized to fit the chamber to form the front end of the predetermined quantity in the chamber.  The dispenser also includes a seal for sealing the first end to form the back of the predetermined volume in said chamber.  Deformation of the container forces the seal means to seal the first end and extend the piston beyond the second end to permit discharge of only the predetermined quantity of contents.
Patent CA-2063095-A1 (CA)
Title: Adjustable brace
Inventor: BICKLE HENRY
IPC: E04G21/26
Filed: 1992-03-16
Abstract: ABSTRACT OF THE DISCLOSURE    The brace is made up of an elongated strut composed of two tubes of aluminum, magnesium, reinforced plastic or other material which is structurally rigid under compression and tension. The exterior walls of each tube adjacent to one end are threaded but in opposite directions and those ends mate with like threads formed on the interior wall of a coupling.          Rotation of the coupling in one direction causes the tubes to advance toward each other with resulting shortening of the effective length of the strut and rotation in the opposite direction causes a lengthening of the strut. An angle-shaped anchor is rigidly connected to the end of each tube opposite the coupling. Apertures are formed in the anchors for receipt of screws,  lag bolts,  nails or the like   for removably attaching the anchors to a floor and to a frame of a wall. The brace serves to support the frame while it is being plumbed.

Title: Internal cumbustion actuated portable tool
Inventor: KELLERMAN RUDOLPH J
IPC: F02B71/02
Filed: 1992-07-10
Abstract: ABSTRACT OF THE DISCLOSURE           An  internal  combustion actuated  fastener driving device in which a simple container supply of fuel under pressure carried in a handle portion of the portable housing assembly feeds to a supply chamber controlled by an actuating valve operable in response to a manual actuating procedure to be spring moved into an operative position.   The movement of the actuating   valve   into   its   operative   position communicates a previously formed charge of gaseous fuel under pressure in a separate charge chamber with a series of nozzles so as to discharge in jet stream formations which aspirate fresh air through inlets to mix therewith in a mixing chamber for passage into a combustion chamber in open condition controlled by a main valve.  The main valve moves under spring bias into a closed position in response to the depletion of gaseous fuel pressure within the charge chamber in timed relation with the crowding of the spent gases from the combustion chamber by the new combustible mixture.   Ignition is in response to the closing of the main valve by a piezoelectric unit.  The piston is driven by the energy of the combustion of mixture which initially is at generally atmospheric pressure. The return stroke of the piston is effected by a spring system which is active only at the end of the drive stroke and beginning of the return stroke.

Title: Force feedback and texture simulating interface device
Inventor: KRAMER JAMES F
IPC: G06F3/033
Filed: 1991-01-30
Abstract: A man-machine interface is dis-closed which provides force and texture information to sensing body parts. The interface is comprised of a force actuat-ing device (900) that produces a force which is transmitted to force applying de-vice (902). The force applying device ap-plies the generated force to a pressure sensing body part. A force sensor (909) on the force applying , device measures the actual force applied to the pressure sensing body part, while angle sensors (911) measure the angles of relevant joint body parts. A computing device (911) uses the,joint body part position informa-tion a determine a desired force value to be applied to pressure sensing body part.     The computing device combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force actuating device. In this manner, the computing device may control the actual force applied to a pressure sensing body part to a desired force which depends upon the positions of related joint body parts. In addition, the interface is comprised of a displace-ment actuating device (901) which produces a displacement which is transmitted to a displacement applying device (902) (e:g.; a texture simulator). The displacement applying device applies the generated displacement to a pressure sensing body part. The for-ce applying device and displacement applying device may be combined to simultaneously provide force and displacement infor-mation to apressure sensing body part:

IPC: B60G11/18
Filed: 1993-03-03
Abstract: The suspension system is a cartridge-type having an axle tube, a central tube and an anti-sway bar disposed in the central tube.  Each cartridge has a torque absorption hub with a substantially cylindrical outer surface to match the inner surface of the axle tube.  A plurality of square torsion bars are disposed between each torque absorption hub and the rotating arm. The arm is connected to the wheel.  The torsion bars are disposed in a circular pattern about the central tube.  The torsion bars pass through a bearing assembly connected with each rotating arm. The bearing assembly includes self-lubricating needle bearings. The relative position of the torque absorption hub with respect to the axle tube may be changed to change the road height of the vehicle.  Torsion bars may be added or removed to change load characteristics.  The unique shock absorber system uses a primary shock absorber to absorb relatively small shock forces, and a secondary shock absorber that is mechanically linked to the rotating arm to operate in a progressive fashion.  This mechani-cal linkage includes a secondary arm and two lever arms.  The secondary arm may be repositioned by a unique locking mechanism whenever the road height of the vehicle is changed.  The entire suspension and shock absorber system is mechanically isolated from the vehicular frame and body by resilient rubber blocks to minimize the transmission of shock forces and road noise to the frame and body.

Title: Acoustic net alarm
Inventor: GUIGNE JACQUES
IPC: A01M29/16
Filed: 1993-03-04
Abstract: ACOUSTIC NET ALARM              Abstract The invention relates to an acoustic alarm for acoustically enhancing fishing gear. The present alarm is an electromechanical device which when submerged in water produces acoustic vibrations containing frequencies which can easily be detected by non-target species, in particular, cetaceans. Attachment of one or more acoustic net alarms to the fishing gear serves to enhance a net acoustically so that cetaceans are alerted to its presence. The device generates a distinct, reproducible acoustic signal at specified time intervals preferably using an electronically controlled, battery-powered solenoid switch. When energized, the solenoid switch causes an actuator to strike the wall of a sealed resonant tube which is enclosed by a hollow spherical casing. Mechanical vibrations are transmitted directly to the spherical casing at the top and bottom of the device where the perimeter of the tube is connected to the casing. When the spherical casing vibrates, it transmits an omnidirectional acoustic signal into the water where it may be detected by cetaceans at a distance.¦
