Abstract: Abstract of the Disclosure A sheet distribution method is provided which, when a stop switch (20) to stop a copying operation of a copying machine (l) or an interrupt switch (21) to interrupt the copying operation is depressed during the copying operation in a collation mode or an assortment mode, inhibits any further copying operation while keep-ing only a copy sheet conveyor section operative to deliver already fed copy sheets to a collator (2). When the number of copy sheets stored in the collator (2) has coincided with the number of fresh sheets fed out in the copying machine (l) during that copying operation, the conveyor section is made inoperative and the next copy start and variation in the operating mode of the machine (1) or preset number of sheet to be copied are permitted.

Abstract: Multiple Height Proportioned Character Generation Abstract A system and method for generating properly propor-tioned alphanumeric characters and symbols in two verti-cal heights with a single character generator and a minimum of associated circuitry.  The bits of video data stored in the character generator are stored such that the vertical segments of diagonal portions of the charac-ters and symbols include no more than two bits per vertical segment of the diagonal portion.  The video data bits representative of the pels of circular portions of the symbols are stored in an arrangement to generate a horizontally elongated elliptical shape when the charac-ter or symbol is displayed in the shorter of the two heights.  Whenever possible, the diagonal portions of characters include no more than two diagonally disposed pels in the single high character size.  For represen-tation of a single dot portion of one of the characters or symbols, a pair of video data bits is stored to generate a pair of horizontally disposed pels on the display when the character or symbol is displayed in the shorter of the two vertical heights.  Translation logic is described to efficiently provide for two sizes of characters with a minimum of additional hardware and with no additional character generator memory beyond that required for the smallest characters or symbols.

Abstract: ABSTRACT    A control circuit for a liquid fuel combustion apparatus which employs a differential amplifier and square-wave generator to maintain a strong constant combustion in the burner until the differential amplifier senses that room temperature has approached a preselected target temperature, at which point the differential amplifier operates to alter the square-wave generator output to gradually reduce the combustion rate in an inverse proportion to room temperature as the target temperature is being reached.  The differential amplifier subsequentially controls the square-wave generator in a manner which causes fuel to be available at a rate necessary and sufficient for maintaining the target temperature.

Abstract: IMPROVED DOUGH FORMING, DIVIDING AND CUTTING APPARATUS    Abstract of the Disclosure An apparatus produces a continuous plurality of generally  rectangular  dough  elements  of  a  controllable weight from a continuous and irregular mass of dough.  The invention includes separate forming, dividing, and cutting portions.  The forming portion includes multiple vertically inclined and horizontal rollers which form the irregularly-shaped  dough mass to have  a  uniform width,  depth,  and consistency.  The dividing portion includes a horizontally-disposed,  multichannel dividing drum and  a plurality of compression rollers which divide the dough from the forming portion into multiple strips of uniform cross section.  The cutting portion includes a multiblade assembly having the shape of and being  occludable with  the channels of the multichannel drum.  The blades are driven at constant speed in a planetary fashion whereby the only motions  of  the blades  relatives to the strips of dough passing through multichannel drum are inward and outward.   The strips of dough  are  thus  divided  into  a  plurality  of  generally rectangular dough elements with a minimum of dough working or  punishment.    The  weight  of  the  dough  elements  is determined by the rotational speed of the dividing drum. Cooperating with the  forming and dividing portions  is a sensing mechanism which senses the amount of dough between the forming and dividing portions.   The sensing mechanism controls the rotational speed of the horizontal rollers in the forming portion to maintain a predetermined amount of dough adjacent the compression rollers to assure uniform compression of the dough.

The threads and rib portions positively secure the sheet metal insert within the molded plastics article or part for receiving a threaded fastener.  The insert may also be used in a metal part or casting or in a wood article, wherever threads are required or desirable.

Abstract: ABSTRACT OF THE DISCLOSURE          A method has been developed for making high strength and high toughness steel having superior toughness even at heat affected zones due to welding.          The method consists of preparing a cast steel of strictly controlled chemical composition by an oxygen converter followed by continuous casting, heating the steel at a considerably lower temperature of 950° - 1050°C and subjecting the heated steel to controlled rolling so that the steel can be rolled at a temperature within an austenite single phase region.          The controlled chemical composition of the steel is maintained to have 0.01 - 0.15% C, not more than 0.6% Si, 0.8 - 2.0% Mn, 0.01 - 0.08% Al, not more than 0.008% S, 0.008 - 0.025% Ti, 0.001 - 0.007% N all being by weight and the balance Fe and incidental impurities.          By virtue of the lowered content of S and small amount of added Ti and N combined with rapid cooling rate obtained through the continuous casting method and through the controlled rolling the rolled steel plate has very fine grained micro structure together with minimum anisotropy in mechanical property even in the direction of the thickness of the plate.          Due to these features, the steel obtained by this method is particularly suitable for weld construction members used at low temperature such as line pipes, ship building and so on.          The steel may further contain one or more of other alloying elements such as Nb, V, Ni, Cu, Cr and Mo.

Abstract: APPARATUS FOR ATTACHING A CERAMIC MEMBER           TO A METAL STRUCTURE ABSTRACT OF THE DISCLOSURE A scroll-wound metallic cushioning bushing in a bore in a ceramic part permits pin-type connection between the ceramic part and a surrounding metal structure while cushioning against vibration and differential thermal loading which may otherwise destroy the relatively brittle ceramic material. In one embodiment, a scroll-wound cushioning bushing is employed in a trip baffle in a flame-holder of an afterburner diffuser section wherein the pins holding the trip step in place are surrounded by the ceramic material and thus protected from the extreme heat found in a flame-holder. In another embodiment of the invention, a large ceramic part is supported on a plurality of pins each passing through a cushioned bushing assembly which permits not only radial relative motion of pins and ceramic part, but also permits limited axial displacement and twisting.

Abstract: ABSTRACT OF THE DISCLOSURE           A generally rectangular-shaped casket-placer and casket-lowering apparatus for supporting a casket over a grave opening dur-ing a graveside service and for lowering the casket into the grave opening, or into the base of a burial vault in the grave opening, for interment after the conclusion of the graveside service includes side rails and end rails.  The front or upper end rail is operatively connected to one of the side rails and transmits rotary motion of the one side rail through a shaft and gear mechanism in a combination braking and power transmission head to the armature of a D.C. motor generator which is located at one of the four corners of the apparatus and controls the speed of lowering of the casket by the apparatus.  The lowering speed of the casket is controlled by an electrical loading circuit which incorporates a D.C. motor generator having an armature which is operatively connected to rotate with the side rails and the front end rail.  The electrical loading circuit includes a zener diode having a predetermined threshold voltage which prevents current flow through the loading circuit and allows rotation of the armature of the D.C. motor generator, and rotation of the side rails driven by downward movement of the casket until a predetermined threshold voltage has been reached, thereby controlling and braking the lowering speed of the casket.  In addition, an improved casket-placer and support-ing arm is disclosed which incorporates a roller and slot locking arrangement.
