Abstract: ABSTRACT OF THE DISCLOSURE A normally hydrophilic microporus material having a polymeric matrix and a filler dispersed throughout the matrix wherein the filler contains active polar groups, is rendered hydrophobic by exposing the material to a reactive compound.  In one preferred embodiment of the invention the reactive compound is a silane or a silazane whereas in another preferred embodiment the reactive compound is a Werner-type complex of fatty acids coordinated with a metal. The treated microporous material is rendered impervious to water-based liquids but remains pervious with respect to vapors or gases, and may be utilized in the fabrication of breathable water repellant clothing and upholstery.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates to a strain relief adapter for an elec-trical connector. Strain relief apparatus for an electrical connector which employs a plurality of insertion blades which have a two-fold purpose has been disclosed. Two adapters may be mounted on opposite sides of an elongated electrical connector and a common hood may be slid over the adapters to provide additional positive retention of the adapters. The present invention provides an improved strain relief which may be installed on the rear portion of an electrical connector which has already had conductors electrically connected to the contacts of the con-nector and which is more suitable than prior adapters for use in connection with termination tools. The present invention provides a pair of one-piece molded structures each of which includes a plurality of pressure members spaced to be received in the respective channels to engage and press against the electrically connected portions of the conductors, conductor clamping means in the form of a comb-shaped edge having a plurality of constructed openings for receiving respective conductors, and a force diversion member extending parallel to, but directed away from, the pressure members and the comb-shaped conductor clamp, also in the form of a comb, to receive the conductors between the teeth thereof for preventing dislocation of the conductors from the insulation-piercing contact portions in response to the application of pulling forces on the conductors.

Abstract: CONSTRUCTION OF ELECTROPHOTOGRAPHIC COPYING MACHINES WITH A      CLEANING UNIT FOR PHOTOSENSITIVE SURFACE            ABSTRACT      A construction of electrophotographic copy-ing machines of the type in which a photosensitive drum is removable from the machine, for inspection or other pur-poses, through an opening formed in a sidewall which open-ing is normally covered by a coverplate.  A plurality of cleaning means which are normally maintained in pressing engagement with the peripheral drum surface are each auto-matically released from the engagement once the coverplate has been dismounted from the sidewall and also returned to the original position so far as the coverplate has been remounted, thereby preventing a damage of the drum as well as a wrong usage of the machine which may be caused by inadvertently failing of resetting each cleaning means. The construction is further effective to adjust the forces with which the cleaning means are respectively pressed against the peripheral drum surface and moreover to de-energize a motor or motors for driving the drum and/or other movable parts as far as the cleaning means is lifted to release from the engagement with the drum surface, thereby permitting an inspection for such movable parts in operation even after the coverplate has been dismounted from the side-wall.

Abstract: ABSTRACT    Modulation systems for electrical signals representing music in which synchronous vibrato and tremolo modulations are applied to a flute signal in one channel, the vibrato being produced by a bucket brigade modulator and the tremolo by a balanced modulator in cascade with the bucket brigade modulator, and in which in a second channel tones other than flute tones, and pedal tones, are separately treated to have independent vibratos, and in which balanced modulators for modifying the amplitude of the tone sign-als are concurrently controlled by a common expression voltage.          In one modification flute signals are vibrato modulated in opposed phases, and passed via diverse filters to a common tremolo modu-lator.  Provision is made for combining the inputs of the channels, the outputs of which are electroacoustically transduced by separated loudspeakers.  Provision is made for slowly varying the frequency of a sub-sonic modulating oscillator, which is either turned off, or operates at about 1 Hz. or about 6. Hz., in proceed-ing from any one of these three values to any other, the rate of variation being such as to simulate the rate which occurs when the modulations are produced by rotation of a mechanical device such as a rotating loudspeaker.

Abstract: "Collection of tars"        IN THE CANADIAN PATENT OFFICE Patent Application entitled "Method of collection of a condensable or divided viscous product, carried by a gaseous current".   (Invention of Fernand-Arthur GEIRNAERT) in the name of AIR INDUSTRIE      ABSTRACT OF THE DISCLOSURE       A process for the collection of a conden-sable or divided viscous product carried by a current of gas, in which filter walls are initially coated with an adsorbent porous and finely divided materiel by causing another auxiliary gas stream carrying this material to deposit it on the filter walls, and then passing the current of gas containing the viscous pro-duct through the filter walls so that the viscous product is captured by the coating of adsorbent material and thus prevented from clogging the filter walls. The filter walls are deformed or shaken subsequently to detach the coating which has adsorbed the viscous product.          The process is especially useful in  cleaning the gas evolved in baking electrodes for aluminium electrolysis cells, since the adsorbent porous and finely divided material can be coke, so that the detached coating can be re-cycled.

Abstract: METHOD AND APPARATUS FOR MAKING A FIBROUS BOARD-LIKE     PRODUCT HAVING A MALE EDGE AND A FEMALE EDGE                          ABSTRACT             Disclosed is a method and apparatus for making a board-like product capable of being formed into a duct section having a male end and a female end for joining sections together to form a duct.  Inorganic fibers coated with a heat setable binder and collected in the form of a blanket are passed between heated moving surfaces to cure the binder in the top and bottom surface portions.  The resultant partially cured blanket is then passed between one or more sets of heated platens to completely cure the binder and to shape the blanket to the desired thickness and con-figuration.  A flat valley depression is formed longitudinally along the blanket down its center portion, and each edge is provided with a male edge, in the first set of platens.          After the blanket has been shaped and cured, it is separated into two strips along the middle portion of the flat valley to form two strips, each having a female edge along one longitudinal edge and a male edge along the opposite edge.          The method and apparatus of the present invention provides an improved female edge, i.e., one having a much smaller radius than produced in the prior art process and capable of forming better joints in air duct systems.
