Abstract: ABSTRACT OF THE DISCLOSURE           A sheet metal fan exhibiting special utility as a radiator fan for an internal combustion engine.  A spider carries the blades on its arms, the arms each hav-ing a radially extending stiffening rib in opposed rela-tion to a complementary rib in its blade to thereby form a tube where the stiffening ribs are radially coextensive.          The stiffening rib on each blade intersects a continuous, blade stiffening channel.

Abstract: Abstract The specification describes a method for the production of densely sintered large ceramic plates of small thickness. The ceramic composition is first extruded by means of an extruder and is then rolled out from the resulting billets in a direction perpendicular to the extrusion axis, this rolling operation is carried out by a further rolling out operation in the axial direction of the billets.  The cutting out of the plates to the desired format is by means of a pressing knife acting perpendicularly with respect to the plate plane.  Following this the plates are dried and fired.

During an incipient fire condition, prior to ignition, a large mass of particulates less than five (5) microns in size is generated by combustible material thereby increasing the con-centration of such size particulates in the atmosphere.  The detector is designed to collect particulates less than five (5) microns in size, rejecting those above this size, and channel the collected particulates at a controlled rate of flow into an ionization chamber wherein the concentration of such particulates is measured.

Abstract: ABSTRACT OF THE DISCLOSURE              A process for the binding of books, magazines and the like without the use of staples or sewing.  The process comprises forming a plurality of spaced notched cuts along the central fold line of each page section to be bound.  Each notched cut extends to one side of the fold line to define a projection portion between the notched cut and the central fold line. All the notched cuts are formed on the same side of the fold line.  Each page section is folded along the central fold line so that the projection  portions project from the fold, nesting  the  page sections  one within another with the projection portions on an inner page section passing through the indentations formed  by the notched cuts in each of the page sections outwardly thereof so that the corresponding projection portions on adjacent page sections overlap.  The overlapping projection portions of adjacent page sections are then glued together.  The process of the present invention avoids the requirement for metal staples or sewing with thread when binding books, magazines and similar products, and reduces significantly the labour involved in manufacture.

Abstract: ABSTRACT OF THE DISCLOSURE Moisture detection systems are known in which interleaved sets of spaced apart wires are connected to a sensing circuit which is activated when moisture bridges wires in the two sets.  It is also known to provide a heater resistor so that the system may detect solid precipitation such as snow.  However, in some systems, the sensing head has to be of large size and efficient operation has not been practical over a wide range of freez-ing temperatures.  The present invention overcomes these problems by pro-viding a compact sensing head comprising sets of wires encapsulated in epoxy and surrounding a small wire wound heating resistor.  The heating resistor melts snow or other solid precipitation and the epoxy is selected to have the same thermal coefficient of expansion as the body member of the head so that there is good heat transfer to the wires and the epoxy does not pull away from the body member of the head.  A heat dissipating resistor is connected in series with the resistor in the head at a first predetermined low temperature so that the head is kept warm.  At an even lower temperature, a thermostat cuts out the heat dissipating resistor so that there is increased current flow to the heater in the sensor head, enabling it to operate down to a very low temperature.
