Patent MX-9707317-A (MX)
Title: Pressurized refill container resistant to sprue cracking, preform and method of making.
Inventor: KRISHNAKUMAR SUPPAYAN M
IPC: B29C49/12
Filed: 1996-03-29
Abstract: A preform (42) and container design for a pressurized refillable plastic container, such as a PET carbonated beverage container, having a base section with increased resistance to sprue cracking. Sprue cracking, which may be a problem in warmer climates, is believed to be caused in prior designs by an entrapment of material between the stretch rod tip (80) and the blow mold base (92) during blow molding of the container, which entrapment causes surface defects in the container adjacent the sprue. These surface defects expand during flexing of the container dome, caused by alternating cycles of thermal shrinkage and expansion during container cleaning and filling. Sprue cracking can be reduced by eliminating a depressed dish adjacent the sprue in prior known refillable containers, and may further be reduced by modifications to the preform and container wall thickness ratios and base clearance height.

Title: Disposable absorbent article having a dual fastening system.
Inventor: BARBARA ANN OWEN
IPC: A61F13/56
Filed: 1998-09-25
Abstract: A disposable absorbent article defines an outer cover, an absorbent chassis and a dual fastening system. The dual fastening system includes a pair of primary fasteners located on the outer cover in one of the waist regions of the absorbent article and a pair of secondary fasteners located on the outer cover in the opposite waist region of the absorbent article. The primary fasteners are configured to engage an outer surface of the absorbent article to maintain the article about the waist of the wearer and the secondary fasteners are configured to engage a body facing surface of the absorbent chassis to support the absorbent chassis. The absorbent chassis is attached to the outer cover at the waist edges and remains at least partially unattached from the outer cover between the waist edges to allow the outer cover to have a blousy appearance. Thus, the disposable absorbent article has an aesthetically pleasing garment-like appearance and improved fit and containment during use.

Title: Direct manipulating direct-graduated release cap for 26-type control valves.
Inventor: SANTORO RALPH JR
IPC: B60T15/04
Filed: 1999-06-25
Abstract: A direct acting release cap for air brake control valves in trains which will allow for the manipulation of the valve characteristics from a direct brake release to a graduated brake release without removal of the cap from the body of the valve. This is accomplished through longitudinal movement of a spool, which directs internal air passages that control valve characteristics. The present invention eliminates the requirement of removing the direct acting release cap from the valve in order to change the working characteristics of the valve, thus resulting in a time savings for the operator.

IPC: C30B25/02
Abstract: 972,511. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Sept. 23, 1960 [June 10, 1960], No. 32753/60. Heading H1K. A method of making a semi-conductor device comprises depositing epitaxially on a monocrystalline semi-conductor substrate of one conductivity type a layer of semi-conductor of the same conductivity type and subsequently diffusing significant impurity into the layer to convert part of it to the opposite conductivity type. In an example, a 111 face of a 0.002 ohm cm. N-type silicon monocrystalline wafer is prepared by polishing with silicon carbide, etching in a mixture of nitric and hydrofluoric acids, cleaning in hydrochloric acid, and washing in de-ionized water. The wafer is placed prepared face upwards on a shaped silicon block 20 in a water-cooled reaction chamber 11. Its surface is first freed of residual oxygen by heating to 1290‹ C. for 30 minutes in a flow of pure hydrogen at atmospheric pressure. After lowering the temperature to 1265‹ C. the hydrogen flow is diverted through silicon tetrachloride 17 contained in a liquid nitrogencooled flask and becomes saturated therewith. At the heated surface of the wafer the silicon tetrachloride and hydrogen react and high resistivity N-type silicon is epitaxially deposited. The resistivity of the deposited layer may, however, be modified by introduction of decomposable halides of activator materials, for example boron tribromide or phosphorus trichloride into the hydrogen flow. Boron is deposited on the epitaxial layer by heating in nitrogen and boron trioxide, and diffused in to form a P-type layer by heating to 1200‹ C. for 90 minutes in a mixture of oxygen and nitrogen. The substrate 45 (Fig. 3) is used as the collector zone of a transistor and is separated from the Player 41 forming the base zone by the high resistivity part 44 of the epitaxial layer unaffected by the diffusion. The Player is next provided with an oxide mask and heated at 1050‹ C. for 30-45 minutes in a flow of oxygen and phosphorous pentoxide to form a localized N-type emitter 42. Electrodes 46, 47, 48 are evaporated on and subsequently alloyed to the respective zones, unwanted parts of the epitaxial' layer etched away to leave the mesa configuration shown and wires 49, 50 thermocompression bonded to electrodes 47, 48. The switching time already lower than that of previous transistors may be further reduced by diffusion of gold into the substrate 45 and epitaxial zone 44, and quenching. A number of transistors may be simultaneously formed in similar manner on a common substrate which is then subdivided.
Patent NL-262812-A (NL)
IPC: C07C201/16
Abstract: Nitro-alkanes or cycloalkanes, prepared by nitration of the hydrocarbon, are purified by contacting a solution of the nitro compound in a hydrocarbon solvent with sulphuric acid containing at most 35% by weight of water, based on the total weight of water and acid, at a temperature between the freezing point of the mixture and the decomposition temperature of the nitro compound, the weight ratio of sulphuric acid (calculated as 100% acid) to the nitro compound being at least 0.1:1 and the hydrocarbon solvent being chemically inert to and substantially immiscible with sulphuric acid at the operating temperature.  The solution of impure nitro compound, for example, of nitrocyclohexane in cyclohexane such as may be obtained by incomplete nitration of cyclohexane, may be contacted first with 85-98% by weight sulphuric acid and then an amount of water added to provide a total water concentration of 14-35% weight when the nitro compound passes from the aqueous phase to the organic phase from which it may be recovered, e.g. by distillation.  The solution of impure nitro compound may first be pretreated by contacting with an aqueous solution of an inorganic base, e.g. 90-99% aqueous sodium hydroxide.  Other nitro compounds such as nitropentane, nitrohexane, nitrocyclopentane and nitrocyclooctane may be similarly treated.  In examples solutions of nitrocyclohexane in cyclohexane are purified. Cyclohexanone oxime may be prepared by catalytic hydrogenation of the purified nitrocyclohexane.  Specification 797,985 is referred to.

Title: Ethylene polymerisation process
IPC: C08F10/00

Catalysts used are improved Ziegler catalysts, e.g. as described in CA appls. 070601 and 083211, made by reducing a transition metal cpd. such as TiCl4 with an organomagnesiumm cpd. and activating the product with an organometallic cpd., esp. an Al trialkyl. Process can be operated with lower concns. of catalyst than known processes so that catalyst residues need not be removed from the polymer.

Title: Cascade decoder for analogue signal conversion - uses clear binary code and has successive stages, each with comparator, contact switch circuit and difference former
IPC: H03M1/00
Filed: 1976-09-15
Abstract: The system for conversion of an analogue signal uses a cascade circuit with N coding stages, and deals with an information signal which is at all times less than E (max) and greater than -E (max). Each coding stage includes a comparator, a modifier and a coupler to the next stage. A typical coder stage (1) comprises an input signal terminal (2), and first and second comparators (28, 29) leading to a modulo 2 summation jnit (30). An output (33) of the latter leads to an auxiliary circuit (35) with a contact switch (37). Another output from the input side of the summation unit (30) leads through an AND gate (31) to a second contact switch (38), which moves between the voltage limits +- E (Mac). The contact switch output leads to a difference former (26) in the output line (3) of the stage.
