Patent CA-1153730-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         The invention describes a self-pressurized three-compartment membrane cell and a process for electrolyzing aqueous alkali metal halide solutions at low cell voltages and high cathode current efficiencies.  Electrochemically-active electrodes are physically bondea to ion-exchange permselective membranes which divide the cell into three compartments.  The mass transport characteristics of the membranes are selected so that water brought into the center or buffer compartment along with the halide ions tends to exceed water transport out of the compartment thereby to increase the pressure in the buffer compartment until equilibrium conditions are reached.  This results in good electrode-to-current collector contact, as the electrochemically-active electrodes which are bonded to the membranes are forced against their corresponding current collectors.

Abstract: ABSTRACT An improved method and apparatus is disclosed for sequentially electrostatic spraying different ones of a plurality of electrically conductive paints from a plurality of paint sources. Each paint source is connected through a separate electrically non-conductive first hose to a manifold and thence through a single second hose to a spray gun. After spraying, at least the first hose which carries the sprayed paint is purged of paint and dryed to electrically isolate the source of the first paint from the manifold when a second paint is sprayed.

Abstract: Abstract of the Disclosure A sail feeder for mounting on a mast formed with a sail receiv-ing slot, said slot having an enlarged entrance for receiving the bolt rope of a mainsail, includes a rigid plate having a pair of legs projecting out from the plate at laterally-spaced locations thereon.  The legs are oriented at the same acute angle relative to the plate and they are toed toward one another so that their free ends are spaced apart a distance less than the spacing between their ends attached to the plate.  The sail feeder is arranged to be secured to the mast at a location directly below the slot entrance.  When raising the sail, the end of the bolt rope at the head of the sail is passed through the sail feeder and thence into the slot via its entrance.  As the sail is raised by the main halyard, the bolt rope is drawn through the sail feeder which aligns the rope with the slot entrance so that hoisting of the sail can proceed without any need of manually aligning the bolt rope with the slot entrance or the feeder.

Abstract: ABSTRACT OF THE DISCLOSURE         FM signals within a predetermined bandwidth representing light-dark variations in a document are transmitted over a communications network to a facsimile receiver.  The FM signals are applied to differen-tiating and frequency doubling means so as to generate trigger signals with substantially equal amplitude and width for application to a single shot multivibrator.  Reset means coupled directly to the input of the single shot multivibrator are responsive to the trigger pulses to reset the single shot multivibrator to the astable state when the frequency of the trigger pulses is sufficiently high that trigger pulses occur while the multivibrator is in a previously initiated astable state.  An average DC voltage detector is connected to the output of the multivibrator such that the average DC voltage represents the ratio of the astable state duration to the stable state duration.

Abstract: Steffen Case 68 Abstract of the Disclosure A seed monitoring apparatus for use with a seed planting machine includes a seed sensor comprising a housing forming a substantially tubular passageway and mounting a light source and three photosensitive elements arranged substantially in a triangular configuration.  The arrange-ment of the light source and the triangular photosensor configuration is such that a seed passing through the tubular passageway will momentarily obscure the passage of light to the photosensor the apex of the triangle, if at all, before obscuring the passage of light to either of the photosensors forming the base of the tri-angle.  The monitoring circuit includes two signal paths in which different methods of counting are used to produce different numbers of pulses in response to signals from the three photosensors.  One or the other of these signal paths is selected automatically in ac-cordance with the rate at which seeds are detected. One of these signal paths includes a delay circuit interposed in the line from the apical sensor while the other includes a one shot circuit interposed in the line from the same apical sensor.  Additionally, a bunch detector circuit produces a predetermined number of additional pulses or counts in response to seeds detected substantially simultaneiously at the two sensors forming the base of the triangle.

Abstract: A SOFT BARRIER FIN WEATHERSTRIP    AND METHOD OF MANUFACTURE ABSTRACT OF THE DISCLOSURE An improved barrier fin weatherstrip is disclosed along with a method of manufacturing the same. The weatherstrip, which is used for sealing openings between fixed and sliding members, comprises a barrier fin preferably formed from polypropylene material, coated or impregnated with wax.  The coated fin has good resistance to air and moisture infiltration.  The fin reduces the noise generated by the weatherstrip sliding on a mating surface and the breakaway force required to reverse the direction of the fin.  The wax in the fin acts as a lubricant between the weatherstrip and the mating surface.  The weatherstrip includes a base strip to which the fin is secured and a longitudinally extending row of pile that is attached to the base strip. The weatherstrip can be made by separating the fin from the pile and applying the waxy material to the exposed side surface of the fin, or the waxy material may be applied to the fin before it is secured to the base strip.

Abstract: A b s t r a c t For drying organic solid materials, such as brown coals, the solid materials are, particularly for the purpose of immediately subsequent briquetting or refinement or gasifi-cation, respectively, preheated and introduced into an atmosphere of saturated steam at super-atmospheric pressure and increased temperature.  After such a first drying stage (1,2) operated with saturated steam, the process water formed in this drying stage is separated and the solid materials are at least partially pressure-released and subsequently further dried within an atmosphere of super-heated steam at a temperature of at least 200 °C of this steam atmosphere.  The steam of this further drying stage (7) is passed along a closed circuit via heat exchangers (10, 11) and brought to or maintained at the required temperature. A portion of the steam passed along a closed circuit, that portion approximately corresponding to the amount of steam having its origin in the water content of the solid materials, is tapped via conduit (12) and used for preheating purposes (Fig. 1).

Cooperating with the control line of this vertically movable door, is a novel latch which has as its operated element a paw which will constrain the door from travel and hence immobilize the door whenever there is slack in the control line; door free fall is prevented and automatic security latching of the door in its closed position is accomplished.  This is achieved by the operative element being a pivoting paw which is biased to indexingly mate into receiving notches placed in the vertical track which defines the door guiding race.  When slack exists in the control line the paw pivots because of baising indexes into one of a plurality of receiving notches located in the track to immobilize the door from movement in either upward or downward direction until the control line is brought taut again.  When the control line is made taut again the paw pivots out of engagement with the track and door travel is restored.
