Patent CA-1068641-A (CA)
Inventor: HARVEY WALTER W
IPC: C25D21/10

Abstract: ABSTRACT OF THE DISCLOSURE     In an electrodeposition cell, high quality metal such as copper is produced on a non-retentive cathode blank at a high current density.  A predetermined close cathode-anode spacing and a gas bubble tube for continuously agitating the electrolyte across the face of the cathode enable effective use of high current densities to electrowin or electrorefine a metal such as copper.  The apparatus includes means for spacing anodes apart from cathodes at a predetermined close distance, optimally less than one inch face to face.  Bubble tubes are inserted in cathode-anode pairs and are supported by bubble tube support members.          An anode for electrowinning includes a non-conductive exten-tion on its base and non-conductive convection baffles at opposite edges of its faces.  Baffles and an extension prevent unwanted electro-deposition on specific areas of the cathode.  Baffles, close spacing, and bubble tubes cause the desired convection of electrolyte throughout the cell.          In an electrorefining cell, convection baffles are positioned on vertical support members within the tank.

Abstract: ABSTRACT OF THE DISCLOSURE           A pendular suspension system for vehicles running on railroad tracks, which comprises pneumatic springs for tilting the vehicles in response to unbalanced centrifugal force, located symmetrically on either side of a central vertical longitudinal plane of the vehicles and being indepen-dent of one another.  Pneumatic springs are arranged to bear upon a base located above the center of gravity of the vehicle bodies and are able to yield vertically and horizontally in response to the resultant imbalance of the centrifugal force to induce increased tilt of the vehicle bodies in addition to the normal cant when the vehicles travel around a curve and become operative only when the train reaches a speed above a predetermined minimum and only when the track has a predetermined degree of curvature to thereby reduce the passenger feeling of unbalanced centrifugal force.

Abstract: ABSTRACT OF THE DISCLOSURE a structurally simple thermostat is disclosed in which a single rivet provides the mounting of all of the switch elements.  The switch elements are located by the rivet and by a portion of the contacts substantially spaced from the rivet to minimize the effect of manufacturing tolerances in the positioning of the switch elements.  A single terminal element supports the movable contact, provides a terminal extension and closes the switch cavity.  The structure is arranged so that ceramic material can be used for the non-metallic parts with a minimum effect created by the relatively loose dimensional tolerances required in the manufacture of ceramic parts.  The terminal member is formed with a shallow dish shaped protection which prestresses the rivet assembly to prevent looseness resulting from differential expansion.

Abstract: ABSTRACT OF THE DISCLOSURE             Contact fusing system for affixing powder images to copy sheets which images are electrostatically or otherwise formed on the copy sheets.  The fusing system is characterized by a pair of fuser roll members one of which is heated and mounted relative to the other roll member to form a nip there-with, the rolls being mounted so that they are permanently in nip.  Rotational movement of the roll members is effected by the main drive of the copier apparatus in which the fuser system is employed and they are operatively coupled to the main drive via a one-way clutch which enables the copy sheet to be manually moved through the fuser system in the event of a paper jam which automatically stops the fuser system along with the rest of the machine.  Since the two rolls are always maintained in nip such manual movement will effect complete fusing of the toner images to the copy sheet.  Accordingly, a copy which has started through the fuser but has not been completely fused can be saved because it can be fused notwith-standing a paper jam.

Abstract: ABSTRACT OF THE DISCLOSURE        A low cost network for use in a television receiver for receiving a video signal and generating therefrom both a control signal for modulating the scan velocity of a CRT electron beam and a delayed video signal for intensity modulating the CRT electron beam with picture information.          The network uses only one delay line for generating the control signal and the delayed video signal.  A video signal is applied to an impedance means followed by a delay means coupled to a reflecting termination.  The impedance of the impedance means is substantially equal to the characteristic impedance of the delay means.  An output terminal from which the control signal is taken is included at a point between the impedance means and the delay means.  The delayed video signal is generated by means responsive to the signal received by the reflecting termination from the delay means.  The net-work may also be used to generate preshoot and overshoot peaking components for peaking the delayed video signal.

Abstract: ABSTRACT OF THE DISCLOSURE   A valve which has a gate of springy sheet material pressing at its peripheral region against an endless valve seat when the valve is in a closed position.  The endless valve seat has a seating surface situated in a predeter-mined plane generally perpendicular to the direction of fluid flow through an opening defined by the endless valve seat.  The gate of springy sheet material is of a dished configuration and has a hollow interior directed toward the opening defined by the endless valve seat when the valve is in a closed position. The dished springy sheet material which forms the movable gate of the valve has a central region situated upstream of the plane in which the seating surface is located, when the valve is closed, and a springy endless peripheral region situated in the plane of the seating surface in engagement with the latter when the valve is closed.  When the dished member which forms the gate is in an unstressed condition, its central region and the peripheral region are spaced from each other in the direction of fluid flow through a distance greater than the distance in the direction of fluid flow when the valve is closed so that the spring force of the springy dished member urges the peripheral region thereof against the seating surface when the valve is closed, a suitable structure being connected to the gate in order to move it between its closed and open positions.

Abstract: ABSTRACT OF THE DISCLOSURE An integrated amplifying gate thyristor is pro-vided with an integral diode in the thyrristor structure in the same semiconductor body.  The diode provides gate assist turn-off capability with the same gate electrode used to turn-on a pilot thyristor of the device.  The common cathode-base region of the pilot and main thyristors also is common with the anode region of the diode.  The current gain of the NPN transistor structure formed at the diode and the common anode-base region at the diode is less than the ratio of IFB/Ig, where IFB is the forward anode current on triggering the main thyristor into the low impedance conduction state by applying a threshold negative gate assist current (IG) and an operating anode-cathode load potential, and Ig is a negative gate current selected to assist in turn-off of the main thyristor.  Preferably, the current gain of said NPN transistor structure at the diode is controlled by selectively irradiating the diode preferably with electron radiation, by adding a shallow impurity lip to the cathode region of the diode toward the main thyristor, or both.
