Patent CA-2052753-A1 (CA)
Title: Uniform loading springs of improved configuration
Inventor: PLEVA WALTER F
IPC: F16F1/18
Filed: 1991-10-03
Abstract: ABSTRACT   The springs in accordance with this invention comprise flat, double surfaced components of resilient,  flexible material, which components have an equal number of uniform projections or protrusions on each side.  The protrusions or projections are rounded or generally spherically shaped, and equally spaced one from another, with the protrusions on one surface of the flat component being precisely intermediate the protrusions on the other surface.  Where protrusions are formed by a press which forms a dent in one surface, dents and protrusions alternate on each surface, whereas the side or surface of the component opposite each solid protrusion is flat.          The springs are controlled by simple beam deflection.  They are inexpensive to produce and may be employed in numerous systems to minimize friction, overheating,  stress,  fatigue or deformation, damp oscillations or vibrations and maintain alignment.

Abstract: SPLINED CLUTCH DRUM MOUNTING  Abstract of the Disclosure An oil passage connection between a shaft and a clutch drum is sealed by intentionally providing an imbalance in the forces acting on splines mounting the clutch drum to the shaft.  The sides of at least some of the splines are angled, so that at least some part of any torque applied between the clutch drum and shaft is resolved into radial components.  By providing a differing number of splines, or an asymmetrical positioning of the splines, the net force can be designed to force the sides of the shaft and the clutch drum adjacent to the oil passage tightly together.  This is most easily accomplished by simply omitting one or more splines from the clutch drum on either side of the oil passage.  With such a structure, the same splines on the shaft can be used to mount gears and the like, which normally require symmetrical distribution of forces.

Abstract: A microwave mixer is formed of three orthogonally oriented  waveguides,  each  having  a  rectangular cross-section defined by a pair of opposed broad walls and a pair of opposed sidewalls wherein the ratio of cross-sectional dimensions typically is 2 : 1.  The mixer includes  an input coupling probe, a mixing  region,  and an output  filter  disposed serially along a first of the waveguides.  A second of the waveguides applies a reference LO signal via the probe to the mixing region, the mixing region including at least one diode with two diodes being employed  in  the  preferred  embodiment  of  the invention.  A section of dielectric board serves to support the diodes of the mixing region, components of  the  filter,  and  the  probe  in  the  first waveguide.    The third  waveguide  applies  an  RF input signal to the mixing region via an input port in  a  side  of the  first  waveguide,  and via  an impedance matching taper and a waveguide section of reduced height which impedes egress of both an IF and an image signal produced in the mixing region by interaction of the LO and the RF signals.  The filter is located at the mixer IF output port for reflecting an image-frequency signal back to the diodes of the mixing region for further interaction with the LO signal to generate additional IF signal in phase with the originally produced IF signal for additional  power  and  a  significantly  higher signal-to-noise ratio.

IPC: A01M21/02
Filed: 1992-04-14
Abstract: ABSTRACT This  invention relates to a manually operated tool for cutting and removing a core of earth containing the roots of a weed or otherwise undesirable plant.   It is common in devices for removing weeds that they require that the person pulling the weeds grasp and pull the weed with the hand which is not operating the tool.   It is common in devices for removing weeds that the process requires that, while digging down with the tool to loosen and pry up the root of the weed, the weedpicker must grasp and pull the weed with the hand not operating the tool.  This procedure is unsatisfactory for several reasons.  The weedpicker must either work on her/his knees or bend over a great deal so as to be able to grasp the weed. To grasp the weed, the weedpicker must dig his fingers into the earth which may be cold, wet, muddy, hard and/or abrasive.  To pull the weed, the weedpicker must exert considerable force with his/her fingers.  Grasping and pulling the weed is very straining for the muscles, joints and tendons in the hand.  Frequently, when pulling the weed by hand, while trying to pry up the root from below with other weed extraction implements, the root breaks just below where it is grasped and the root is left in the earth where it regenerates a new plant.  These methods of weed removal are very tiresome and unpleasant and also involve considerable disturbance of the soil and are very damaging to the appearance of a lawn.

Title: Combination infrared and air flotation dryer
Inventor: SEELEY WILLIAM R
IPC: F26B3/28
Filed: 1992-09-15
Abstract: ABSTRACT    Apparatus for the non-contact drying of a web of material with a combination of infrared radiation and heated air.  The apparatus  includes a dryer enclosure in which is mounted a plurality of air bars in air-receiving communication with upper and  lower  headers  both  above  and  below  the  web  for  the contactless convection drying of the web.  Mounted between the air bars are infrared gas fired burners.  In order to accommodate the infrared burners between the air bars, spacers are fitted on the header system supplying air to the air bars.  The drying surface  of the web  is thus alternately heated by  infrared radiation and then scrubbed by high velocity air to remove the moist boundary layer.  Since the burners are completely enclosed, all heat energy is captured in the exhaust system of the dryer assembly and a portion can be used to supply hot convention air back to the dryer.  The remaining air is hot enough to be used in other convection dryers in series with the instant combination dryer,  or have its heat recovered through the use of heat exchanger.

Abstract: Précis Nous plaçons tous notre linge sur un support sur un cintre et ensuite on accroche notre cintre chargé sur une barre de soutien.  Il est évident que plus les cintres sont nombreux sur la barre et plus le linge suspendu est pesant, tout cela  rendra bien difficile le choix et la facilité à prendre un morceau de linge quand il est perdu au milieu d'une grande rangée de linge, souvent très serrée.            Pour remédier à cet inconvénient, nous avons conçu un petit chariot dont le rôle serait de se promener sur la barre de soutien et dû même coup, transporter le linge qui est suspendu à son anneau par en des-sous.  Même dans une rangée abondante, nous aurions beaucoup de faci-lité.            Avec l'aide de cette invention, les cintres ne glissent plus mais ils roulent.  Donc avec cet instrument, moins d'effort à fournir, moins de bruit à entendre et moins d'usure à notre barre de soutien.            Un autre avantage de cet instrument c'est qu'il est adapté à toutes les barres de soutien actuelles existantes et à tous les cintres aussi. C'est vraiment un instruments nouveau que le public aurait avantage à posséder.
