Patent CA-2060584-A1 (CA)
Inventor: MARTENS ERNST
IPC: B28B1/08
Filed: 1992-02-04
Abstract: In the extrusion of hollow core concrete slabs, the density profile across the slab is controlled by the vibration of a hammering plate forming one side of a packing chamber through which the concrete is extruded. Vibrations are imparted to the hammering plate by a vibrator that acts to produce vibratory motions in the plate that are not parallel to the direction of extrusion. With two vibrators producing vibratory components both in the direction of extrusion and outwardly to opposite sides of the packing chamber, the flow of concrete to the side edges of the slab is augmented. In an auger-type extruder, this allows the outer augers to be run at a slower speed than otherwise, thus increasing their service life. The vibratory frequency may also be reduced considerably, thus reducing the noise generated by operation of the apparatus.

Inventor: MENARD MICHAEL J
IPC: A61F13/56
Filed: 1992-09-25
Abstract: A novel method for manufacturing a layer of a laminated, disposable absorbent product, such as a fluid-permeable cover layer, an absorbent core layer or a fluid-impervious backing layer thereof, with a comparatively small amount of waste matter. The method comprises the steps of longitudinally cutting a continuous web of starting material according to a cyclic pattern constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips, each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product. The invention extends to integrating this method into an operation for manufacturing disposable absorbent products, and to a novel apparatus for carrying out the methods according to the invention and the resulting products.

Filed: 1992-10-02
Abstract: An electrical interruption device is disclosed in which a space efficient spiral spring activates current interruption.  The spring is characterized by coils which wind continuously about and approach a central axis, with successive coils of the spring having reduced radius to pass axially through the center of an outwardly adjacent coil.          The spring may further be made to assume a flat condition with the spring coils lying flat, nesting interposed between adjacent coils.  Advantageously, the spiral spring is conical in shape and is tensioned in a reverse loaded configuration wherein the coils of one end of the spring are pulled axially inward, through and past the coils of other end.  Preferably the reverse loaded conical spring forms part of a thermally sensitive device which includes a housing having disposed therein a plunger which is in a biased relationship with the spring.  The plunger extends beyond the housing to provide electrical communication with the remainder of the electric circuit, and is held in place against the force of the spring by a meltable solder.  On a predetermined condition causing the solder to melt, the plunger is released, whereby it is moved by the force of the spring into the housing and out of electric communication with the remainder of the electric circuit.
