Title: Hydrocyclone conduit
Inventor: CHARETTE ERNEST J
IPC: D21D5/24
Filed: 1991-07-30
Abstract: HYDROCYCLONE CONDUIT                  Abstract of the Disclosure Hydrocyclone separators of the type used to separate contaminants from pulp suspensions in paper mills are connected to feed, accept, and reject conduits using a conduit apparatus in which both feed and accept portions are preferably bent from smooth plate material. The feed and accept portions preferably include generally flat surfaces through which holes are drilled for making connections to the feed and accept nozzles of the hydrocyclones.  The smooth plate material eliminates the tendency of pulp to build up on the conduit walls and in the nozzles, thereby avoiding the problems that can occur when such build ups break loose.  The nozzles of the hydrocyclones are preferably attached by placing a resilient sealing member around the circumference of the nozzle, and inserting the nozzle into an aperture formed in a generally flat wall of the conduit until the sealing member engages the inside wall of the aperture.   app10740

Patent CA-2049999-A1 (CA)
IPC: A47F5/08
Filed: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus is disclosed for the manufac-ture of J-shaped display hooks with balled ends in a single  manufacturing  operation,  without  requiring separate handling of the display hook for the bending and ball-forming operations.   A continuous length of wire  is  advanced  incrementally  and  gripped  tightly adjacent its forward end.  The wire is severed by means of a cutting and forming bar, which also bends the base portion of the wire at right angles to the main axis of the wire.  While the wire remains tightly gripped at its forward end, and continue to be supported adjacent its base by the cutting and forming bar, a ball-forming die is advanced against a projecting forward end of the wire, upsetting the wire end and forming an enlarged end of  generally  spherical  configuration.    Immediately thereafter, the wire is released at its forward end, and a rotary plate  is actuated,  causing a bend-forming element to travel through a generally circular path concentric to a cylindrical forming drum.  This opera-tion, which is carried out while the base portion of the wire  remains  locked  in position,  forms a generally semicircular bend in the previously balled end of the wire.   Both the ball-forming operation and the hook-forming bend are carried out in sequence, while the remainder of the hook remains locked in position and oriented in a predetermined manner, so that the various elements of the resulting hook are properly shaped and aligned.

IPC: B65D51/20
Filed: 1991-09-12
Abstract: ABSTRACT     The invention relates to a container neck (10) and closure (12), particularly useful for foil-sealed containers.  The neck (10) and closure (12) include complementary threads (14, 16) or projections and complementary tapered surfaces (18, 20) which are adapted to form an interference fit and seal the closure (12) to the neck (10) at a region clear from the lip (30) of the neck (10) and the crown (120) of the closure  (12).   Any foil seal  (28)  present on the container neck (10)  remains free from contact with the closure (12) during application and tightening.  Preferably the neck (10) includes a recessed lip (30, 32) further to protect the seal and to inhibit drop formation.  An outer edge of the container lip may be chamfered to provide a pull tab on the foil seal.  Additionally, the foil may be of a larger diameter than the lip of the container, so that it provides an overhanging edge of foil to facilitate the removal of the foil, but not of such a large diameter that it touches the inner surface of the closure.

Abstract: MAGNETORESISTIVE SENSOR BASED ON THE SPIN VALVE EFFECT          ABSTRACT OF THE DISCLOSURE      A magnetoresistive (MR) sensor comprising a first and a second thin film layer of a magnetic material separated by a thin film layer of a non-magnetic metallic material.  The first  ferromagnetic  layer  is  magnetically  soft.   The magnetization  direction  of  the  first  layer  of  magnetic material   is   set   substantially  perpendicular  to  the magnetization of the second layer of magnetic material at zero applied field, and the magnetization direction of the second layer of magnetic material is fixed.  A current flow is produced through the MR sensor,  and the variations in voltage across the MR sensor are sensed due to changes in resistance of the MR sensor produced by rotation of the magnetization in the first layer of magnetic material as a function of the magnetic field being sensed.  The variation of the resistance with the angle between the magnetizations of the first and second layers of magnetic material has been defined as the spin valve (SV) effect.   It is also shown that, by a suitable direction of the current with respect to the fixed magnetization, the (SV) magnetoresistance can be added    constructively    to    the  usual    anisotropic magnetoresistance.

Title: Control pedal apparatus for a motor vehicle
Inventor: CICOTTE EDMOND B
IPC: G05G1/40
Filed: 1990-04-26
Abstract: A control pedal apparatus for adjusting a control pedal of a motor vehicle such as for example a brake pedal, an accelerator pedal, or a clutch pedal. The mechanism includes a pedal arm, an adjustor member, and a bracket secured to the fire wall of the vehicle. The mechanism allows the position of the pedal pad to be adjusted slidably on the adjustor member without disturbing the position of the particular control element actuated by the pedal assembly, and selectively moves the pivot axis of the pedal assembly to maintain a fixed mechanical advantage of the pedal assembly irrespective of the position of adjustment of the pedal arm on the adjustor member. Coasting slots allow the pivot axis to be selectively moved during adjustment of the assembly but coact in response to depression of the pedal to fix the position of the pivot axis in any adjusted position of the pedal arm so that the pedal assembly pivots positively about the instantaneous assembly axis in any adjusted position of the pedal arm. The adjustment of the pedal arm is accomplished by the rotation of a screw engaging a nut on the pedal arm with the screw being driven by an electric motor.
