Title: Method for Hot Relining or Production of Refractory Materials and Powder Mixture
Inventor: ROBYN PIERRE
IPC: C04B35/03
Filed: 1993-07-31
Abstract: This invention refers to method for hot relining.    During ceramic welding the oxidized gas and mixture of refractory and combustible powders are directed towards the surface and the combustible powder is burned with the heat release which is sufficient at least for the partial welding and softening of refractory powder, as the result of which the cohesion mass is produced which is tightly attached to the surface. In order to avoid the possibility of forming the refractory phase of the burned mass with low resistance and thereby to increase the heat resistance of the welded mass the contents of the combustible powder in the mixture is limited up to 15% (weight.), with this the combustible powder comprises at least two metals which are selected from aluminum, magnesium, chromium and zirconium; the greater part (weight) of the refractory powder consists of at least one or several oxides which are selected from magnesium, aluminum and chromium oxides, and the molar proportion between dioxidosilicium and calcium oxide in the refractory powder (where available) meets the following formula.  [SiO2] %   0,2 + [CaO]%     The elements of the combustible powder can be entered into it in the form of alloys.

Patent DK-164622-C (DK)
Inventor: HAFERL PETER EDUARD
IPC: H04N3/16
Filed: 1982-02-15
Granted: 1992-12-14
Abstract: A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle.

Title: Print engine for color electrophotography
Inventor: PALM CHARLES S
IPC: G03G21/14
Filed: 1986-10-17
Granted: 1991-08-06
Abstract: "IMPROVED PRINT ENGINE FOR   COLOR ELECTROPHOTOGRAPHY"            Abstract of the Disclosure An improved full color electrophotographic print engine using flexible belts to carry a photosensitive electrostatic image developer and a transfer belt for building up composite developed images. Each belt, and an optical scanner, are driven by mechanically independent motors which are synchronized by an electronic digital controller implementing precise servos. The use of the flexible belts allows the machine to be relatively inexpensive, very small compared to previous full color print engines, and yet maintain precise registration of color composite images. An improved fuser mechanism with increased dwell time at constant machine speed is also shown. The fuser includes a pair of spaced-apart rollers, both of which urge a sheet of image receptor against the heated roller over a predetermined angular portion of the roller. The machine is specifically designed to be used interchangeably with an optical bench source as a copier or with a laser bench as a laser printer. Improved copy quality monitoring by sensing actual amounts of toner deposited on a photoreceptor belt is also shown. Also, improved downwardly facing gravity-fed toner deposition modules are shown including an embodiment which has a purely magnetic gate for opening and closing the toner supply.

Patent CA-1303211-C (CA)
Title: Synchronous changeover
Inventor: MELLING LAURENT A JR
IPC: H04N5/268
Filed: 1987-03-16
Granted: 1992-06-09
Abstract: Abstract of the Invention A synchronous changeover device detects both peak amplitude and pulse width, automatically switching between sets of signals when a fault is detected without a noticeable glitch.  The signals of each set are peak detected and combined so that if any signal of a set falls below a predetermined value a FAIL signal is output to a switch timing and control circuit.  The FAIL signal, together with the sync signals from the sets of signals, causes an electronic switch to switch from one set of inputs to another between sync pulses, resulting in a synchronous changeover.  Further the signals are input to a start/stop counter via a multiplexer under control of a microprocessor.  The counter counts the number of pulses of a reference signal between the start and stop of a selected signal pulse, and the microprocessor determines if the pulse width is within acceptable limits.  Out of limits pulse widths cause the microprocessor also to generate the FAIL signal to automatically switch between sets of signals.

Title: Multi-section mattress overlay for systematized pressure dispersion
Inventor: SPANN DONALD C
IPC: A61G7/057
Filed: 1987-10-06
Granted: 1992-05-19
Abstract: ABSTRACT OF THE INVENTION   A polyurethane foam mattress overlay has several sections defined in a relatively flat support surface thereof.  The sections are longitudinally disposed so as to correspond with different parts of a user's body. Each such section has predetermined support characteristics which are selected in relationship with such characteristics for the other sections so as to define systematized support.  Specific numerical ranges and interrelationships for such sections are disclosed. A plurality of projections are formed in each surface section.  In general, the cross-sectional area of such projections at the overlay support surface or at a given depth therefrom is the same within each section, but differs from one section to another.  Separation distances between such projections may also vary with the respective sections.  In such manner, tailored support characteristics in respective sections provide engineered support for all parts of a user's body. Further, side edges of the projections may be bevelled and/or include a radius of curvature to enhance independent action of the projections.  Also, channels for dissipating heat and moisture may be provided, and have characteristics which vary with the different support sections.  Further disclosed is an effectiveness index which takes into consideration the thickness, indentation load deflection (i.e. stiffness), and density of a given pad.

Title: Moving node wave isolator for drafting plotter
Inventor: CLEVELAND LANCE
IPC: B41J13/10
Filed: 1988-02-04
Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE      A wave isolator (18) is provided for large format drafting plotters (10) for preventing waves in the draft-ing medium (16) from traveling up the platen (14) and adversely affecting the pen (20) and its operation and reducing acceleration related vertical scalloping of an-gled lines. Such waves in the medium are generated by the motion of the paper during the plot ing operation.     The wave isolator comprises at least one strip (22a) of flexible material secured to the platen and of substan-tially the same length.  Preferably, a polyimide film is used, having a coating of a thermoset acrylic resin with additives including conductive carbon black and polyethyl-ene.     In operation, when the medium is moving upward, the wave isolator deflects under the increased inertial load, and air trapped between the medium and the platen exits at the sides of the medium, dissipating some of its energy. When the medium is moving downward, the wave isolator sees a negative change in load and responds by flexing upward, tending to increase the volume of air between the medium and the platen, creating a low pressure area which sucks air in at the sides of the medium, again dissipating its energy.     Use of the wave isolator of the invention permits high speed, high acceleration plotting on both sheet and roll media without the aid of firmware solutions.
