Abstract: MULTILAYER CERAMICS COATINGS FROM THE CERAMIFICATION OF    HYDROGEN SILSESQUIOXANE RESIN IN THE PRESENCE OF AMMONIA             ABSTRACT     Hydrogen silsesquioxane resin can be ceramified at low temperature in the presence of ammonia, with or without platinum or rhodium catalysis, to form a ceramic coating on the surface of a substrate.  The nitrided silica coatings produced are useful as interlevel dielectric films or for planarizing and protecting the surface of electronic devices.          For further surface protection, overcoating the nitrided silica with an additional layer of a passivating ceramic material and a top layer of a barrier ceramic material is also described.

Abstract: MULTI-DISK SYNCHRONIZER Abstract of the Disclosure A multi-disk synchronizer is provided wherein the complicated portions of the elements required for the neutral detent mechanism, the blocking mechanism and to prevent over-travel of the shift collar all are provided in a blocking insert held in a slot in the shift collar.  The blocking insert preferably is cast, and this mechanism can be used with any type of synchronizer.  In addition, the synchronizer rings for the multi-disk synchronizer is formed by stamping and pressing heavy sheet metal rather than by casting and machining a part.  The combination of the blocking insert and the stamped synchronizer rings significantly reduces the machining required to manufacture the synchronizer.

Granted: 1992-11-24
Abstract: ABSTRACT OF THE PRESENT INVENTION     The circuitry of the present invention taps a DS0 data stream and outputs a timing signal to drive terminal multiplexers. Even if the data bit stream is lost, the present invention continues to provide proper clocking signals. A composite clock (bit and byte clock) is provided by the present invention with the bit clock at 64 KHz and the byte clock at 8 KHz in the preferred embodiment. To avoid the problem of phase shift over long distances (limiting cable length) the present invention phase adjusts the digital bit stream clocking signal with a 360 degree delay, giving the appearance of advancing the signal in phase. An additional delay of one frame width is applied to the signal. A negative phase delay equivalent to cable runs from 0 - 1500 feet in 500 foot increments is also applied. In the preferred embodiment, a shift register is tapped in reverse order to accomplish this phase delay.

Abstract: ABSTRACT   OF THE DISCLOSURE         A cavity formed in a mold is preparatorily expanded to a volume sufficient for preventing the flow of resin flowing into said cavity from being divided and held at a temperature capable of maintaining the resin in a flowing state.  Into this expanded cavity, thermoplastic resin heated and in a molten state is injected after the quantity required for obtaining a molded article or more is preparatorily measured.  The cavity is reduced in volume before the total quantity of said measured thermoplastic resin is injected into the cavity.  This cavity reduction operation is controlled so that no unfilled portion which will cause a flow mark remains in the cavity when the cavity is reduced to a volume equal to the sum of the volume of the molded article and a volume of molding shrinkage due to the cooling of the thermoplastic resin.  At the time of this cavity reduction, injection pressure is reduced to a pressure which would not obstruct back flow of the thermoplastic resin likely to have been overcharged into the cavity as a result of cavity reduction and which permits the injection of the resin to any unfilled portion likely to exist in the cavity.

Abstract: The present invention relates to a method for manufacturing zinc hydrometallur­gically from zinc-containing starting materials. The method comprises one or more leaching stages, one or more solution purifying stages and one or more electrowinning stages for recovering metallic zinc from the leaching solution obtained. The method is operating with a closed solution circuit. A predeter­mined part volume of the solution obtained in the electrowinning stage or stages is withdrawn and concentrated by evaporation so as to precipitate any magne­sium and manganese present in the part volume in the form of metal salt crys­tals. The precipitated crystal mass is separated from the residual liquid phase. The liquid phase in this manner purified with respect to magnesium and manga­nese can be recycled to the leaching process or utilized for some other purpose. When the process is carried out in a sulphate environment, the solution obtained in the electrowinning stage or stages is concentrated to a sulphuric acid concen­tration of at least 60% by weight.The precipitated crystal mass, which has but a small volume, may be dumped to no disadvantage. In accordance with a preferred embodiment, the crystal mass is re-dissolved in a small quantity of water, thereby enabling practically all the zinc content to be recovered in metallic form, by electrowinning.

Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. During the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming devices pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations.The abovementioned forming principle works less well if the packing containers are not to be completely filled but have a certain air space, so-called head-space. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome if the contents are mixed prior to filling with gas, preferably sterile air, in appropriate proportions, so that the contents obtain a foam-like character, using a gas volume which is in a suitable proportion to the air space of the finished packing container. The invention relates to a method as well as to a manner of proportioning the contents in the manufacture of packing containers.

Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the net shape aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.
