Patent CA-1078002-A (CA)
Inventor: MORAW ROLAND
IPC: G03G16/00

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method of repeated recording and quenching of deformation images on a recording material composed of a photoconductive thermoplastic recording layer arranged on a dielectric support layer and ap-paratus therefor. The development and quenching is effected by means of thermal heat supplied to a conductive layer on a film rostrum above which the recording material, which carries a charge image, is transported. Before and during the thermal quenching by means of a movable corona device electrostatic charges are applied to the recording layer, said charges having a polarity oppo-site to that of the charge image on the recording layer. This charge image is produced by the application of an electrostatic charge and the exposure of the charged surface of the recording layer to an image pattern. The high voltage of the corona device is reversible when the corona device is switched from forward to backward movement.

Abstract: METHOD FOR REMOVING SULFUR DIOXIDE FROM EXHAUST GAS Abstract of the Disclosure The invention is a method for preventing the formation of scale in a system for the removal of sulfur dioxide from an exhaust gas.  The system to which the invention relates comprises contacting the exhaust gas with an aqueous solution containing an organic acid alkali metal or ammonium salt, blowing air or oxygen into the resulting solution, reacting the solution with calcium hydroxide or calcium carbonate to form a precipitate of calcium sulfate, filtering of the calcium sulfate and recycling the supernatant liquid for contact with the exhaust gas. The method of the invention comprises causing the solution to contain not less than 0.3 percent by weight of crystal-line calcium sulfate immediately prior to the contact with the exhaust gas and causing the concentration of alkali metal or ammonium sulfite in the aqueous solution to be less than 2 percent by weight immediately after the contact.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to refrigerator cabinets and, more particularly, to a door frame structure for use with such cabinets.  In contemporary refrigerated cabinets, heat is absorbed by conduction from the air outside the refrigerator and is conducted through the metallic door frame around the edge of the door and into the cold portion of the door frame which is in contact with the cold air inside the refrigerator. The present invention overcomes this defect of the prior art by providing a channel-like structural member for use as a refrigerator door frame, having a generally U-shaped cross section including a first flange, a second flange, and an intermediate central portion wherein the improvement comprises a thermally insulative thermal barrier interposed between said central portion and said second flange, and holding those portions in rigid spaced-apart relationship.

Abstract: Abstract of the Disclosure A light module comprises several neon lamps and resistors encapsul-ated in a translucent plastic material. Terminals accessible for impressing a voltage across the lamps are also provided. Preferably the lamps are pro-vided on one side of a printed circuit board and the resistors on the other.      Neon lamps do not generate as much heat as incandescent lamps and can thus be more closely confined without burning out than incandescent lamps. The use of several neon lamps introduces a redundancy feature which permits the device to operate satisfactorily even if one lamp burns out. The encapsula-tion protects the lamps, resistors and connections generally in handling. In a particular application, the encapsulated module operates as the light source in a push button elevator call switch, the module being movable and transmitting a manually applied force to the movable contacts.

Abstract: ULTRASONIC TRANSFER PRINTING WITH MULTI-COPY, COLOR AND LOW AUDIBLE NOISE CAPABILITY                ABSTRACT OF THE DISCLOSURE           A printing or copying system in which ink is transferred from an ink-bearing medium to a printing medium through the use of ultrasonics.  The ink-bearing medium may be an ink ribbon, carbon paper or the like which is in contact with a printing medium such as paper.  Ultra-sonic energy is applied to the ink-bearing medium through transmission fibers, wires or bundles thereof, causing the viscosity of the ink to be reduced due to the ultrasonic vibrations and conversion of the ultrasonic energy into heat such that the ink is transferred to the printing medium.           Multi-copy capability is achieved by having alternate layers of carbon paper or the like in contact with the paper.

Abstract: ABSTRACT           A reclining chair is provided with a shiftable chair chassis which travels from a rearward, upright sitting position along a supporting base to a forward position from which the chair may be reclined without striking the wall behind the chair.          The chair chassis is normally locked against recline from its rearward, upright sitting position but may be released by the extension of the footrest, which also unlocks the chair chassis for forward travel.  Preferably, the chair chassis is mounted upon a downwardly and forwardly inclined track on the chair base so that the weight of the seated occupant is sufficient to shift the chair chassis forwardly on the base upon release of the lock, while counterbalancing means actuated by the forward movement of the chair chassis returns the chair to its rearward position when the occupant rises from the chair.

Abstract: AUDIO SYSTEM WITH ENHANCED SPATIAL EFFECT            Abstract of the Disclosure An audio system comprising a record player, tape deck, microphones, or other signal source which generates stereo signals supplied to two main speakers for reproduction; the stereo signals are added together to afford an intermediate signal which is subjected to at least two successive equal delays to generate a plurality of delayed signals which are summed with the intermediate signal in predetermined amplitude and phase relation to generate a spatial effect signal that is essentially free of noticeable reverberations or echoes.          This spatial effect signal is reproduced by a separate speaker in the same listening space as the main speakers to add ambience and diffuseness to the total sound field.  In the preferred construction two delayed signals are employed, delay is effected with the signals in digital form, and the summing ratio for the intermediate, first delayed, and second delayed signals is approximately 1:2:1 with the intermediate signal and the second delayed signal in phase opposition.  A corresponding monophonic system is also disclosed.
