Title: Pyrolysis and analysis system
IPC: G01N31/12
Filed: 1972-12-08
Abstract: 1388609 Determination of organic carbon &c. ENVIROTECH CORP 8 Dec 1972 [10 Dec 1971] 56796/72 Heading G1B A selected element occurring in a fluid sample in a predetermined form (for example organic carbon in waste waters) is determined by a method comprising (a) removing from the sample (which in the embodiment of the figure has been introduced into boat 21 via port 20) any of the selected element present in a form other than the predetermined form (CO 2  and low mol. wt. organic compounds) by volatilization in zone 12, (b) treating the volatilized products in column 31 to remove from them by sorption components containing the selected element in the predetermined form (the low mol. wt. organic compounds), the residual gases (such as carbon dioxide) passing through water stripper 34 to detector 36, (c) desorbing the sorbed components from column 31, (d) pyrolyzing in zone 14 the desorbed components together with the remainder of the fluid sample (from the boat) to give a gaseous product and (e) determining the gaseous product. The boat may contain copper oxide as oxidation agent for the residue in the boat and for determination of organic carbon the gaseous pyrolysis product may be converted to methane by reaction over nickel catalyst in zone 13. The gas flows are arranged to exclude flow of hydrogen from chamber 16 into zone 14. There is a reference to use of the method above for separate measurement of ammonia and low molecular weight amines, and high molecular weight organic nitrogen compounds, when the detector may be flame thermionic or microcoulometer detector means. The apparatus of Fig.2 (not shown) may be used for an oxidative pyrolysis determination, when the sample is heated in a single zone to a lower temperature for the volatiles-removal step (a) and to a higher temperature for the pyrolysis step (d), and an infrared detector may be used to determine carbon dioxide as gaseous product.

Abstract: 1,246,468. Semi-conductor devices. MOTOROLA Inc. 6 Dec., 1968 [26 Dec., 1967], No. 58056/68. Heading H1K. An electronic device is mounted in a container comprising an anodized base-plate 20, a plate 21 and a lead frame 24 carrying three upstanding tubular members 25, 26 and 27, and the device 29, which may be a semi-conductor element, the whole being embedded in a plastics encapsulating material. The anodizing on the base-plate 20 is sufficiently thin not to form a heat barrier, the base-plate itself carrying the plate 21 which is conductive and has an insulating layer 28 of plastics material, and semiconductor elements 30 on its surface. A lead frame 24 is disposed on this conductive plate 21 and insulated from it by the insulating layer 28. This frame carries a semi-conductor die 29, and the three tubular members 25, 26, and 27, which are welded or soldered to the frame. These tubular members serve as contacts to the frame. The device is embedded in a plastics encapsulating material after removal of parts of frame 24 by cutting 24A as required to avoid unwanted connections. Mica washers 31 are disposed over the apertures 22 beneath tubular members 25, 27 to prevent ingress of plastics material during encapsulation. Flanges 34, 35 oh base-plate 20 hold plate 21 in place prior to encapsulation in a press. To prevent the extending portion of the base-plate 20 from flexing during this encapsulation stage a deformation 38 in the form of semi-cylinder is provided. Holes are provided in this deformation to allow the plastics material to pass through and lock on to the base-plate. Locking is also provided by the tubular members 25, 26 and 27, whose upper surfaces remain outside the encapsulation as do contacts 12.

Abstract: 1424334 Expanding metal UNION CARBIDE CORP 28 Dec 1972 [29 Dec 1971] 59800/72 Heading B3A [Also in Division B5] A process for expanding the cross-section of a blank of low-melting-point alloy with the attendant formation of one or more voids 4 of reduced pressure, comprises venting the voids during the increasing of the cross-section so as to equilibrate the pressure within the voids with the ambient pressure and thereby regulate the integrity of the expanded blank. In Figs. 2 and 4 a blank 2 is heated in a Carverpress and secured by hot-tack adhesion to perforate mould plates 1a, 1b which are moved apart to effect the expansion. Each void is vented through an aperture in the mould plate. In an alternative embodiment a continuous blank can be fed between a pair of heated belts. The form of the voids in the expanded cross-section is controlled by the form of the mould plates which are usually of porous or non-porous metals. Many different plates are described, some having patterned open-work arrangements, to form various designs on the surfaces of the formed blanks. In some cases the plates are not stripped from the blanks and result in a laminate. If necessary the mould plates can be masked to prevent adhesion in certain areas. Examples given for the use of the blanks made by this process indude structural elements, containers, partitions, packaging, automobile framing and furniture.
