Title: Improvements in and relating to a new iodinated derivative, its process of preparation and therapeutic applications
IPC: C07C69/22
Filed: 1965-05-20
Abstract: Pure ethyl monoiodostearate is prepared by reacting hydriodic acid with olive oil and transesterifying the iodinated glyceric esters thus formed so as to convert them into iodinated ethyl esters according to conventional methods, and then subjecting the iodinated ethyl esters to a molecular distillation in two stages, so as to eliminate, in the first stage, the non-iodinated, di-iodinated, and tri-iodinated impurities, and the unsaponifiable part coming of olive oil, and to rectify in a second stage the ethyl monoiodostearate. The product is then treated with crystallized sodium sulphite to remove traces of free iodine, followed by filtration and sterilization.ALSO:Pure ethylmono iodostearate is used both therapeutically and in x-ray contrast applications.  In the former case the ethyl monoiodostearate is made into capsules, tablets, ointments, suppositories, and injectable ampoules, with the usual pharmaceutically acceptable vehicles, and can be administered orally, rectally, or by subcutaneous or intramuscular administration for use in treatment of arteriosclerosis and angina pectoris.  In X-ray contrast applications the ethyl monoiodo stearate is put into injectable ampoules, advantageously as such, under an inert gas, and can be administered in most organs of the body.

Title: Folding cameras
IPC: G03B19/12
Filed: 1972-04-09
Abstract: 1329536 Folding cameras POLAROID CORP 9 May 1972 [10 May 1971] 21550/72 Heading G2A A folding camera has first and second housing sections coupled for movement between folded and extended positions, and first and second optical elements of a viewing device coupled to the first housing section, so that as the housing sections move between folded and extended positions, the first optical element at least also moves between folded and extended positions. The camera shown is of the same single lens reflex type as is disclosed in Specification 1292239, in which a reflex member 56 is pivoted from the viewing and focusing position of Fig. 1 to an exposure position. The viewing device 64 has a forward portion 90 and a rearward portion 92. Portion 92 is pivoted to housing sections 12 and 16 by pins 13 and 15 respectively. Within device 64 is a concave mirror 68 and an eye lens 70 in respective housings 100 and 102. Housing 100 is pivoted to a pair of blocks 93 on forward portion 90 by pins 104, and has at its upper extremity a pair of pins 106 which can slide in camming slots 124 in flanges 122 forming part of the viewfinder cover 116. Housing 102 is pivoted at its upper end between flanges 98 of arms 96 which extend upwardly from forward portion 90. The erecting system for the viewfinder 64 includes a pair of links 117 pivoted at one end to flanges 98 by pins 118, and having camming slots 120 in which can slide pins 110 at the lower end of housing 102. To reduce the admission of ambient light, a collapsible shade 126 is provided. This is formed of a number of thin U-shaped blades 128 pivotally attached to rearward portion 92 by pins 108. When the camera is collapsed into the folded position of Fig. 3, housing section 14 pivots clockwise about pin 15, so that viewfinder portion 92 moves towards housing section 16. Thus as links 117 engage against section 16 they pivot anti-clockwise about pins 118. Pins 110 slide along slots 120 so that the lens housing 102 pivots clockwise about pins 108, and lens 70 is pivoted into its folded position (Fig.3). The viewfinder cover 116 is now moved downwards manually, so that it pivots anti-clockwise about pins 108. This causes the pins 106 to slide along the slots 124, so that the mirror housing 100, and hence mirror 68, pivots clockwise into the folded position. In this position the shading blades 128 telescope together. The camera may be maintained closed in the folded position by a latching arrangement 144, 146. To erect the camera, cover 116 is grasped and lifted. The mirror housing 100, lens housing 102, and blades 128 are all spring-loaded, so that they automatically assume their operative positions.

Title: Semiconductor device fabrication
IPC: H01L29/00
Filed: 1966-05-16
Abstract: 1,145,879. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 16 May, 1966 [28 May, 1965], No. 21727/66. Heading H1K. In an insulated gate FET, the conductivity of that part of the channel not covered by the gate electrode is enhanced by heating in a suitable ambient after applying the gate electrode. The device is produced by heating a P-type silicon wafer (10) in steam to produce silicon oxide layers (14, 15), photomasking and etching to produce windows (17, 18) and heating in phosphorus pentoxide vapour to produce N- type source and drain regions (19, 21), Figs. 2 to 4 (not shown). The remaining oxide layers are removed by etching in hydrofluoric acid and the wafer is re-oxidized in dry oxygen. The oxide layer (24) on the upper surface is photomasked and the wafer etched to remove the oxide layer (25) on the lower surface and to form windows (27, 28) in the upper oxide layer (24) over the source and drain regions (19, 21), Figs. 5 to 7 (not shown). The wafer is then heated in a reducing ambient such as hydrogen or a mixture of hydrogen and argon or nitrogen, forming gas (10 : 90 hydrogen : nitrogen) being mentioned, to form an inversion layer (30) under the remaining parts of the oxide layer, Fig. 8 (not shown). A metal layer (40) is deposited over the surface of the wafer and is masked and etched to produce contacts (41, 43) on the exposed parts of the source and drain regions (19, 21) and a gate electrode (42) on the oxide layer covering the channel (30), Figs. 9 and 10 (not shown). The metal layer (40) may comprise a layer of chromium on which is vapour deposited a layer of gold or silver. As shown, Fig. 11, the gate electrode 42 is offset towards the source region 19 and the conductivity of the part 33 of the channel region 30 nearest to the drain region 21 is increased by heating the wafer in an atmosphere of hydrogen or forming gas, the gate electrode 42 acting as a mask. Leads are applied to the electrodes 41, 42, 43 by soldering or thermocompression bonding. A plurality of devices may be produced in the wafer which is then diced, and the individual devices are mounted on metallic headers and encapsulated.

Title: Method of treating gaseous bodies
IPC: B01D53/04
Filed: 1943-09-28
Abstract: In a process of removing adsorbable matter from a gaseous body by employing a multi-bed apparatus and using the beds successively, the gaseous body is passed through the absorbent material of one bed until it has adsorbed a predetermined quantity of adsorbable material, the bed is maintained in this state for a predetermined time preferably equal to half the time of the adsorption step, desorption fluid (e.g., steam) is then passed, in the opposite direction to the gaseous body, through the absorbent material in order to regenerate it (preferably for a time equal to three-eights of the adsorption period), after which the regenerated adsorbent material is maintained in this state for a time equal to a fraction (preferably a quarter) of the desorption period and is then dried by the passage of warm air and finally cooled to approximately room temperature (e.g., by passing cold air through it, these last two stops preferably occupying a time equal to half the adsorption period), this cycle being repeated with the adjacent bed starting at the end of the first half of the adsorption period in the first bed. The process may be carried out in the apparatus of Specification 586,128, as part of the overlapping cycle of operations described therein.

Class 94(i) A wrapping machine for forming block-ended wrappings open at one end of the kind in which one of the side folds is made first and then a narrow tuck and then the final side fold comprises means for moving an article against a strip of wrapping material located tranversely of the path of the article and then between top and bottom plates which form the wrapper into a U about the article and thereafter between a pair of narrow side tuckers. Mechanically operated tuckers are arranged to move downwards and forwards with and over the sides of the article and fold the parts of the strip extending laterally in the plane of that face of the article nearer to said tuckers to form one pair of long side folds said tuckers being positioned and shaped to finish folding said side folds just before the narrow tucks are being formed whereby the side folds lie adjacent to the sides of the article and the narrow tucks lie on the outside of said side folds. A batch 5 of cigarettes is moved by a pusher 4 on an endless conveyer between two thin side plates 11 which are carried by a bar 10 reciprocated by a cam-operated link 16. The plates 11 thus move along with the batch 5 as it engages a strip I ot wrapping material positioned across its path, a rear guide 8 of the strip being pivotally moved away from a front guide 7 as this takes place so that movement of the strip with the batch is unhindered. The batch 5 and side plates 11 then carry the wrapper with them under a top plate 6 which, with the bed of the machine, folds the wrapper into a U about the batch. Pivoted tucker members 22, actuated by cam operated link means 28, 30, then move down on either side of the top plate 6 to engage and fold down over the strips 11 the top horizontally extending side portions of the wrapper. The end tucks are next formed to lie on said folded down portions, as the batch moves forward between long narrow stationary side tuckers 21, the side plates 11 having been withdrawn, and the bottom side portions of the wrapper are then folded up by stationary folders 33 positioned at the end of the tuckers 21.

Title: Method of treating partly used nuclear fuels
IPC: G21C19/48
Filed: 1962-06-07
Abstract: Partly used nuclear fuel containing uranium or plutonium carbide is decontaminated from fission products by treatment with anhydrous or aqueous hydrofluoric acid to form UF4 and/or PuF4, or PuF3.  The hydrofluoric acid may be in gaseous or liquid form and reaction may take place at a temperature up to 700 DEG  C.; for example, the used fuel is diluted with alumina and treated as a fluidized bed with hydrogen fluoride vapour mixed with nitrogen, argon, or hydrogen. For complete decontamination, the product may be converted to the hexafluorides by the action of fluorine at 400 DEG  C., and the hexafluorides purified by distillation. Alternatively the lower fluorides may be (a) reduced with calcium or magnesium metal in the presence of carbon or graphite to re-form the carbides; or (b) converted to oxides with steam at high temperature.
