Inventor: KUSZYK JACK ANDREW
IPC: B22D41/08
Filed: 1988-01-07
Abstract: There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal (10) with an oxidant, and (2) one or more fillers (12) embedded by the matrix. The metal alloy (10) and permeable mass of filler (12) having at least one defined surface boundary (14) are oriented relative to each other so that formation of the oxidation reaction product will occur into said mass of filler (12) and in a direction towards said defined surface boundary (14). On heating the metal (10) to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler (12) to said defined surface boundary (14). The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of any residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary (14), thereby producing a self-supporting ceramic composite.

Abstract: The invention concerns a test method and test apparatus for detection and localization of manufacturing defects in an electronic arrangement that contains test structures according to standard IEEE 1149.1, hereafter "the tested arrangement" by means of selected current diagnosis. The selected current diagnosis significantly broadens the area of application of wiring tests according to standard IEEE 1149.1 (JTAG) on component boards that contain both components with standardized test structures and traditional components without the standardized test structure. Broadening of the area of application and the increased coverage of wiring tests are based on measurement of changes in the value of the operating current that an arrangement takes from a power source by means of a computer-control test arrangement that contains a current measurement device and a control device for the test structures, when the test arrangement by means of the standardized test structure placed in the test arrangement has guided the test arrangement into a desired controlled static state or states. <IMAGE>

Abstract: An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (eg, a drug) through a body surface (eg, skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize. Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current.
Patent GB-814663-A (GB)
Title: Thermal decomposition of acetic acid
IPC: C07F9/17
Filed: 1956-01-12
Abstract: Acetic anhydride and/or ketene are obtained by subjecting acetic acid to thermal decomposition in the presence of an alkyl ester of a sulphur-substituted phosphorus oxy-acid.  Suitable esters are, for example, those of formula <FORM:0814663/IV (b)/1> in which R1, R2 and R3 are the same or different alkyl groups, Y and X being oxygen or sulphur, at least one X or Y being sulphur.  Examples of such compounds are diethyl S-methyl thiolophosphate, diethyl S-ethyl thionophosphate and triethyl thionophosphate.  Advantageously the decomposition is carried out in a heated reaction vessel constructed of or lined with a stainless steel alloy containing nickel and chromium.  The products which include ketene and acetic anhydride mixed with unreacted acetic acid may be recovered as such or as a mixture of acetic anhydride and acetic acid by permitting the ketene to react with the acetic acid.  The catalyst is preferably used in an amount of 0.03 to 0.5 per cent based on the weight of acetic acid supplied to the reaction zone.  After passing through the reaction zone the products are cooled and may be mixed with a water entrainer such as benzene, toluene, chloroform or ethylene dichloride.  It is also desirable that ammonia, a nitrogenous base or other basic material should be added either with the catalyst or to the products to neutralize the catalyst.  In the examples acetic acid is heated in a tube of high silica glass, containing strips of stainless steel, in the presence of triethyl thionophosphate to give acetic anhydride.

Title: Method and apparatus of making oriented tubular film
IPC: B29C48/10
Filed: 1972-01-11
Abstract: 1383001 Oriented tubular film FMC CORP 11 Jan 1972 [4 March 1971] 1143/72 Heading B5B In an apparatus for making oriented tubular film, a thermoplastic polymeric melt is extruded through the annular orifice 13 of die 11, and the film 15 so formed is inflated via conduit 23. During the passage of the film through chamber 17, it is cooled only to within the orientation temperature range, and substantially prevented from expansion, by a current of cooling gas fed to annular nozzle 31 via openings 37 and which issues from the continuous annular orifice 39 defined by lips 41 and 43. The gas stream flows concurrently with successive portions of the film as it advances through the chamber and is discharged at its uppermost end 33 into the ambient atmosphere. The arrangement of perforated sizing rings 45 to 59 of gradually increasing diameter, separated by baffles 65 which extend beyond the perforations, which are offset one to another, serves to control the radial expansion of the film to the desired size and to ensure that the pressure flow characteristics of the cooling gas remain constant throughout the operation. The films emerging from the chamber passes to the speed controlled moving surfaces indicated generally at 19 which serve to grip the film without flattening it and advance it at apredetermined initial speed. Said surfaces include pairs of of like spaced rolls 67, 69 disposed in one common plane and pairs of like spaced rolls 71 and 73 disposed in another common plane, the common planes 75 and 77 being parallel to each other and at right angles to the axis of the die 11. Idler rolls 87 in the planes 75 and 77 minimize distortion of the film as it is advanced by the rolls 67, 69, 71 and 73 and prevent radial expansion of these areas of the successive film portions which are not engaged by, but are aligned circumferentially with, the rolls. Rolls 67, 69, 71 and 73 are suitably surfaced with rubber and idler rolls 87 with "Teflon" (Registered Trade Mark). On leaving the rolls 67, 69, 71 and 73 the film expands as shown, and the radially expanded and molecularly oriented film then passes through an annular nozzle 25 where it is quenched by a cool gas, and the film is collapsed by collapsing frame 22 as it advances towards the nip rollers 21. The orientation of polyvinyl chloride film is exemplified.

Abstract: 468,967. Hydraulic shock-absorbers. ARMSTRONG, F. G. G. Jan. 16, 1936, Nos. 1376 and 18069. [Class 108 (iii)] In a hydraulic shock-absorber, particularly for vehicles, flow of liquid between a pair of cylinders 15, 16 through a restricted passage in a valve-seating 30 is controlled by a tapered needle valve which is displaceable relatively to an externally-adjustable valve seating proportionately to the relative displacement of the elements to be checked and which is formed with one or more tapering flat surfaces 27 at its tapered end which merge into one or more flat faces 26 of uniform width extending along the shank 25 of the valve to prevent complete closure of the restricted passage. As shown, the valve-spindle 24 is slidable in a boss 23 in the shock-absorber casing and controls transverse passages 28, 29 extending from the cylinders 15, 16, the valve being spring-pressed against a cam-surface 13 on the operating shaft 12. The seating 30 is formed in a threaded plug 35 so as to be manually adjustable. The valve shank may be in two parts separated by a transverse wedge displaceable in a direction normal to the axis of the valve under the action of fluid means remotely-controlled, e.g. from the dashboard of a vehicle. Alternatively, the wedge may be omitted and one portion of the shank formed barrel-shaped to facilitate selfalignment of the valve.
