Abstract: ABSTRACT OF DISCLOSURE          This invention relates to a process of coating using a   sprayable   coating   composition  in   a   spraybooth   that communicates  with  a  water  wash,  the  water  wash  permitting contact between airborne components of the sprayable  coating composition that enters the water wash and scrubbing water of a high volume, low energy wet scrubber operating at an inlet and outlet pressure difference of less than about 10 inches of water.   More  particularly,  this  invention  relates  to  an improvement  in  the  coating  process  which  comprises  (A) spraying  in  the  spraybooth  a  scrubable  coating  composition comprising a volatile organic compound that boils above about 98°C  at  atmospheric  pressure,  is water  soluble  above  about 0.6%  by weight  at  20°C  and  is  transitory  in  the  scrubbing water;  (B) capturing in the scrubbing water a volatile portion of  said  scrubbable  coating  composition wherein  the volatile portion comprises an amount of the volatile organic compound and wherein an ingredient of the scrubbing water reacts with a portion of the amount; and (C) maintaining a concentration of the  volatile  organic  compound  and  reaction  products  of  the volatile organic compound in the scrubbing water below that at which  efficiency  falls  below  about  10%  (preferably  higher, e.g. at least 30%) of a maximum efficiency.

Abstract: AUTOMATICALLY COMPENSATING OBJECT DETECTION CIRCUIT     ABSTRACT    Antennae located in the doors of an elevator car are in circuit with a balanced bridge detector coupled to an oscillator.  Increased capacitance to ground pro-duced by a person or object between the doors creates a bridge disbalance, which gives rise to the production of a bridge output signal whose level is proportional to the change in capacitance.  Each time the car door opens at a floor, the signal level from the bridge obtained at an intermediate door position is stored as a reference indi-cative of the capacitance change resulting from dynamic environmental and structural factors.  When the doors are fully open, the output from the bridge is compared with the stored signal level for detecting the additional capacitance created by a person or object between the doors and controlling door movement accordingly.

Abstract: PROCESSES FOR SEVERING HOLLOW FIBER MEMBRANES             ABSTRACT OF THE DISCLOSURE     Processes are disclosed for severing a plurality of hollow fiber membranes comprised of thermoplastic material which membranes are arranged in the form of a bundle and also sealing the bores of the membranes in an essentially fluid-tight manner.  The severing and sealing of essentially all of the hollow fiber membranes in the bundle can readily be accomplished without any significant decrease in membrane performance or strength.  The severing and sealing of the hollow fiber membranes is accomplished by passing a heated member through the bundle in a path transverse to the orientation of the hollow fiber membranes wherein the temperature of the heated member is above the melt temperature of the hollow fiber membranes.  Advantageously, the hollow fiber membranes which are severed in accordance with this invention can have a significant void volume and may be anisotropic with a thin, dense skin.

Abstract: ABSTRACT          The present invention discloses both a method and apparatus whereby the integrity of elongate magnetically permeable member(s) can be determined even if coated with a non-magnetic substance or embedded in a non-magnetic body.          A magnetic yoke having field winding(s) and sensing winding(s) is used to induce a time varying magnetic field in the mag-netically permeable member(s).  Changes in the reluctance experienced by this magnetic field alter the output of the sensing winding(s).  The invention finds particular application to testing conveyor belts, but is also applicable to steel cables, and both rubber and concrete bodies, including steel reinforcing.

Abstract: ABSTRACT OF THE DISCLOSURE          A tarpaulin securement member is disclosed for securing a tarpaulin sheet to a supporting rod.  The member comprises a base member integral with a concave seat, a top plate being fixedly secured to the base plate member and sandwiching the tarpaulin therebetween.  In the preferred embodiment, the top plate member is provided with a cavity or recess which facilitates the threading of strap fasteners between the tarpaulin and the base mamber, the strap members being preferred as clamping means for securement of the seat section of the base member to a supporting rod.  In another preferred embodiment the base member is cast from malleable material as an integral single-piece unit inclusive protrusions having the shape of rivet stems.  The invention simplifies the manufacture while reducing susceptibility of the tar-paulin to leak at its joints with the supporting rod.  By the same token, the securement is strong and reliable in operation.

Abstract: ABSTRACT OF THE DISCLOSURE An iron blue pigment ("DIN 55 906") is prepared by precipitating white paste and then oxidizing the white paste. Alkali metal ions such as sodium ions and potassium ions, cyanide or hexacyanoferrate(II) ions, and iron(II) ions are used as starting materials. The iron blue pigment of the pre-sent invention contains potassium in an amount of between 7.0 and 9.0% by weight, preferably between 7.6 and 9.0% by weight, sodium in an amount of between 0.5 and 2.0% by weight, preferably between 0.5 and 1.5% by weight, has a tinting strength, when tested in accordance with "DIN 53 204" and "DIN 53 234" exceeding the tinting strength of "Vosscnblau 705", the German colour stan-dard for iron blue pigments, by between 5 and 15%, and has colour differences (determined in accordance with "DIN 53 204" and "DIN 53 239" in combination with "DIN 6174" with "Vossenblau 705" as standard) which are:           .DELTA.L : - 0.7 to -1.5 .DELTA.a : - 0.5 to +0.3 .DELTA.b : - 0.6 to -2.3 .DELTA.C : + 0.5 to +2.0 To save potassium ions in the preparation of iron blue pigments of the present invention the precipitation of white paste is effected in two phases. The alkali metal ions which are used in the precipitation of white paste are potassium ions used in the first phase and sodium ions used in the second phase. The soluble byproducts of the reaction are then removed, potassium salts are added, whereupon, the white pulp is aged and oxidised, in a conventional manner, and recovered as an iron blue pigment. The iron blue pigment can be used as a pigment in the preparation of printing inks, paints, and enamels, and as a colourant in fungicides.

Abstract: ABSTRACT OF THE DISCLOSURE         A stove has a firebox for burning solid fuels such as wood or coal, an opening in a side wall communicating with the firebox, a window housing surrounding the wall opening and pro-truding laterally from the stove, a transparent window pane mounted in the window housing in alignment with the wall opening and through which the interior of the firebox may be viewed, and a door assembly arranged in the window housing between the window pane and the wall opening.  The door assembly includes a door having first and second panels, with hinges connecting the lower edge of the first door panel to the upper edge of the second door panel for pivotal movement about a first horizontal axis,  The first door panel is in turn connected to the window housing for pivotal movement about a second horizontal axis arranged above the first horizontal axis.  Inclined track members extend down-wardly along the interior sides of the window housing and inwardly away from the window pane.  A handle accessible through a vent opening in the top of the window housing is employed to pivotally adjust the door between a raised open position at which the lower edge of the second door panel is in contact with upper sections of the track members and the door panels are in a generally con-fronting relationship extending rearwardly away from the track members towards the wall opening, thus exposing the window pane to the wall opening, and a lowered closed position at which the door panels are generally coplanar and at rest against the track members, thereby shielding the window pane from the wall opening and the firebox interior.
