Abstract: D-4,129   C-3227 ENGINE KNOCK CONTROL WITH KNOCK PULSE DURATION ADJUSTMENT Abstract of the Disclosure A vehicle mounted, spark ignited, internal combustion engine subject to bursts of ringing knock vibration of varying duration corresponding to knock of varying intensity includes apparatus effective to generate pulses in response to the bursts and of corresponding duration.  Further apparatus delays the trailing edge of each pulse by a common predetermined duration to favorably reduce the ratio of the durations of such pulses before application to apparatus effective to control a knock reducing parameter of the engine.  The reduced ratio of duration between short and long pulses provides more uniform control over the total range of knock intensity.  The engine may also include apparatus to delay the leading edge of each pulse by a common predetermined duration to eliminate short noise pulses and improve the knock signal to noise ratio.  If so, this apparatus is inserted prior to the trailing edge delay apparatus and the common predetermined duration of the latter is greater than that of the former.

Abstract: ABSTRACT OF THE DISCLOSURE         Organopolysiloxane modified organic polymers are prepared by reacting, at elevated temperatures, a mixture containing an organic poly-mer free of silicon atoms and having C-bonded hydroxyl groups, with an organopolysiloxane containing groups selected from the class consisting of Si-bonded hydroxyl groups, alkyl groups which are bonded to silicon via oxygen and mixtures thereof, in the presence of water which is in excess of that formed during the reaction.  This results in the provision of sub-stantially higher molecular weight organic polymers having C-bonded hydroxyl groups.  The so-produced organopolysiloxane modified organic polymer has a viscosity which is less likely to change in the presence of water.

Abstract: KEYLEVER PAWL TUBE SPRING AND KEYBOARD UTILIZING           A KEYLEVER PAWL TUBE SPRING               Abstract of the Disclosure A hollow tubular rubber or rubberlike deformable member is supported by a plurality of character keylevers in a typewriter keyboard and constrained against movement within the typewriter by supporting surfaces on the keylevers such that the tube engages the keylever pawls carried by the keylevers.  As the keyboard of the type-writer operates, an interposer will force the keylever pawl rearward to provide complete restoration of the selection interposer.  If the pawl did not rotate and the keylever is still in its depressed position upon the completion of the keyboard cycle, the selection logic would not be cleared and any following keylever input would result in a malselection.  Also, interposer loading would prevent keylever restoration.  The force of the interposer against the front edge of the keylever pawl will force the keylever pawl to pivot about its pivot stud and to locally compress the tube spring, formed out of a resilient pliable rubber-like material.  Upon the restoration of the keylever to its rest position and withdrawal of the keylever pawl from engagement with the interposer stem, the forces generated within the tube spring during local deformation will be released and will act to restore the keylever pawl to its normal at rest position.  The tube spring extends across the entire keyboard engaging all keylever pawls in the keyboard, thus eliminating the need for a separate spring or spring finger to be engaged with each keylever pawl and each keylever.

Abstract: FERRITIC STAINLESS STEEL HAVING GOOD                      CORROSION RESISTANCE     Abstract of the Disclosure A 10 - 35%cr ferritic stainless steel stabilized with 0.20 - 1.00% of Nb wherein Nb% ? (8 x C% + 2.0%) with impurities, such as carbon, nitrogen, phosphorous, oxygen and sulfur reduced to given levels is disclosed.  By reducing the sulfur content to a level of not greater than 0.002%, preferably less than 0.001% or in cases where copper and/or nickel is added, to a level of not greater than 0.005%, the corrosion resistance of the resulting steel can markedly be improved.  Since the ferritic stainless steel of this invention also exhibits a combination of good surface appearance and formability, it can be substituted for certain austenitic stainless steels not only as a general corrosion resistant material, but also as a material for making external automotive trims and so on.

Abstract: Abstract:     Disclosed is an electrophotographic member having an amorphous-silicon photoconductive layer containing hydrogen, wherein the distance between a portion of the layer in which light illuminating the layer is absorbed therein until its intensity has decreased to 1% of that at incidence, and the interface of the layer opposite to the light incidence surface thereof is at most 5 µm, whereby the residual potential of the photoconductive layer can be reduced.  That part of the photoconductive layer which constitutes the electrophotographic member and which is at least 10 nm thick inwardly of the layer from the surface thereof to store charges is made of amorphous silicon that has an optical forbidden band gap of at least 1.6 eV and a resistivity of at least 1010.OMEGA..cm.  Further, within the photoconductive layer, there is a region of amorphous silicon whose optical forbidden band gap is smaller than that of the surface part disposed at a thickness of at least 10 nm.  By forming the region of narrower optical forbidden band gap within the photoconductive layer in this manner, the sensitivity of the layer to light of longer wavelengths can be enhanced.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are provided herein for forming inverts in the manhole base of a manhole assembly using a single pour technique.  In the single pour technique, the invert is formed simultaneously with the formation of the manhole base through the steps of first providing a mold having a hollow interior space for forming the manhole base to be cast therein.  Rings are then mounted within the interior space of the mold to define openings to be provided in the side-walls of the manhole base being cast in the mold, the rings having central openings defining the central axis of the openings to be formed in the manhole base being cast.  A mold member is then disposed in the mold, the mold member defining an interior surface of a floor of the manhole base being cast and having raised portions supported thereon defining an invert to be provided in the floor of the manhole base, the mold member having openings at the end walls of the raised portions, the centres of the openings lying on a line parallel to the longitudinal axis of its associated raised portion. Finally, a reciprocating activating means is activated thereby slidably to extend movable alignment members through each opening in the invert forming mold member and through an opening in an associated one of said mounting rings, thereby precisely to align the center of each ring along the longitudinal axis of a respective one of the raised portions preparatory to casting.

Abstract: ABSTRACT           Suitably complexed cupric solutions can deposit conductive copper films electrolessly on properly catalyzed non-conductive substrates, at plating bath pH values in the range of about 2.0 to 3.5, using a non-formaldehyde reducer such as hypophosphite.  Certain conditions are critical to successful results:  (1) ability of the complexer selected to chelate copper at pH values of 2.0 to 3.5 at elevated temperatures (140° to 160°F); (2) avoidance of certain anions, such as halides and acetates, in significant concentrations in the plating solution; and (3) provision of an "active" catalytic surface on the non-conductive substrate.

Abstract: Heat Exchanger Core With Varied-Angle Tubes Abstract Heat exchangers depend for efficiency upon maximizing fluid flow, such as air, through their fins about tubes extending through the fins.  The air flow, particularly at the ends of a heat exchanger, can some-times be of a significantly reduced amount owing to flow restrictions caused by the construction of, or arrangement of elements in, a heat exchanger.  A core of a heat exchanger of the present invention utilizes a relatively varied angular arrangement for tubes in the core which improves air flow, particularly at the ends of the core.  Air flow is thus improved over a portion of the heat exchanger to increase heat transfer, as well as purging of debris, for the folded or zigzag core arrangement described.
