Abstract: A toilet-tank discharge valve has a main-valve body that can be lifted off of its face, by release-activating an auxiliary valve with an activating mechanism, as a consequence of negative water balance in an associated discharge compartment. A supplementary auxiliary valve is associated with the discharge compartment and opens at least briefly as a result of discontinuance activation of the activating mechanism, producing a positive water balance in the discharge compartment until the main-valve body closes. A valve of this type, with an auxiliary valve, makes it possible to discontinue the flushing process ahead of time. A shift mechanism in the connection between the activating mechanism and the supplementary auxiliary valve shifts the supplementary auxiliary valve from whatever limiting position it happens to be in into the opposite limiting position in response to a discontinuance activation. This makes it possible for both release and discontinuation activation to be initiated with uniform pressure strokes. This not only makes the device easier to operate but also makes remote activation possible with simple devices.

Abstract: A waterbox for a shell and tube heat exchanger is disclosed. The waterbox is attached at one end of the heat exchanger to a tube sheet through which heat exchange tubes extend. Nozzle connections are made to the waterbox through a top member having an access opening which projects onto an area of the tube sheet through which the heat exchange tubes extend. The openings of the nozzles project onto areas on the tube sheet through which no heat exchange tubes extend. A removable cover is positioned over the access opening in the top member so that, when fluid flow conduits are connected to the nozzles on the top member, the conduits and removable cover are positioned relative to each other to allow removal of the cover without disturbing the connections between the conduits and the nozzles. In an alternative embodiment, the conduit connections are made through the back wall of the tube sheet rather than through the top member. This allows use of a waterbox with a removable top member having no nozzles.

Abstract: This invention relates to coated abrasive products having a resinous binder which holds and supports abrasive granules on a backing sheet. 
<??>In the manufacture of coated abrasives, the make coat resinous binder and abrasive granules are first applied to the backing, then the size coat resinous binder is applied, and finally, the construction is fully cured. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g. heat resistance. 
<??>With polyester or cellulose backings, however, curing temperatures are limited to about 130 DEG  C. At this temperature, cure times are long. The long cure times necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include formation of defects at the suspension rods, inconsistent cure on account of temperature variations in the large festoon ovens, sagging of the binder, and shifting of abrasive granules. Furthermore festoon curing areas require large amounts of space and large amounts of energy. 
<??>This invention provides a coated abrasive product comprising abrasive granules adherently bonded to at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the binder material can be used in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.

Abstract: PURPOSE:To prevent a drying operation from being suspended even if a zero cross signal is not detected, in the case a motor driving a drum is subjected to phase control. CONSTITUTION:A control part compares the speed of revolution stored in a RAM with the speed of revolution detected by a revolution speed sensor by an arithmetic part, and decides an increase or decrease tendency of the speed of revolution from its difference. Whenever a zero cross signal is detected by a zero cross detecting circuit, the speed of revolution is controlled by adjusting a phase of a power source supplied to a motor based on a result of decision. On the other hand, when there is no output of the zero cross signal for a prescribed period due to a certain cause (S10), the control part drives the motor without adjusting the phase (S27).

Abstract: A hydraulic percussion device comprises a housing defining a longitudinal cylinder, a piston longitudinally reciprocal in the cylinder and subdividing same into a front compartment and a rear compartment, and a tool engageable longitudinally with the piston at the front compartment. The compartments are alternately and oppositely hydraulically pressurized to move the piston forward to strike the tool while traveling at an end speed and to move the piston backward away from the tool, the rate of alternation being a frequency parameter and the speed being a force parameter. A controller varies at least one of the parameters by detecting how much the piston rebounds from the tool after striking same and operating the control means in accordance with how much rebound is detected. How much the piston rebounds can be detected by sensing the pressure in one of the compartments immediately after the piston strikes the tool. As rebound increases the pressure in the rear compartment increases relative to a set point or pressure in the front compartment decreases relative to a set point, and vice versa. Rebound can also be detected by sensing the pressure in one of the compartments and at one of the sides of the source and operating the control means in accordance with the differential between these sensed pressures.

Abstract: A video-scrambling system induces a random wobble i.e., time shifting, in the location of active portion of the video frame, without affecting the horizontal sync signal and colorburst in each video line, thus providing both security and concealment. The security is enhanced by filling in the gap between the nominal beginning of active video and the actual beginning of active video with a synthesized video signal which replicates the adjacent active video using a digitally generated filling pattern. Also, a random noise overlay further conceals the location of the gap. Additional concealment is provided by wiggling in time the location of the horizontal sync signal using one or two frequencies and also by randomly altering the location of the vertical sync signal. The NTSC digital encoding in accordance with the invention is simplified by using only two channels, chrominance and luminance, and by a heterodyne circuit for chrominance stability. NTSC encoding is enhanced by providing detail normally lost, by use of the chroma channel. Additionally, a non-standard video signal may be provided with a portion of the colorburst on the front porch of the horizontal blanking, thus allowing use of a relatively simple decoder.

Abstract: A self-testing and self-repairing memory system (3-15) is presented as well as a method for using it and a method for making it. This memory system is constructed from memory chips (3-1 that have passed an abbreviated wafer probe test. After the memory system (3-15) is assembled, it tests itself to locate defective memory cells (3-5). The memory system (3-15) may decide to correct these defective memory cells (3-5) or it may decide to correct them using an error correction code engine (3-3). This memory system (3-15) tests itself during field use to locate defective memory cells. Once these defective memory cells (3-5) are located, the memory system (3-15) uses the error correction code engine (3-3) to correct these defective memory cells (3-5). When the error correction code engine (3-3) becomes overburdened with defective memory cells (3-5), then the memory system (3-15) replaces these defective memory cells (3-5).
