Abstract: 1351556 Steam generation COMBUSTION ENG Inc 6 Sept 1972 [7 Sept 1971] 41418/72 Heading F4A In a liquid/vapour separator 10 for separating water from steam, a plate 29, having a plurality of openings 40 therethrough, carries a series of cylindrical members 44 each member surrounding an opening 40 and a rotating vane assembly 42 is positioned in the bottom of each cylindrical member 44 for imparting centrifugal force to the water/steam mixture flowing upwardly therethrough. A housing 48 surrounds each cylindrical member 44 and each housing 48 is provided with a plate 50 having a central opening 54 therethrough. The plate 50 acts to form a collecting place for water separated out in the chamber 58 above the plate 50 but also inhibits water separated out in chamber 52 below the plate 50 from becoming re-entrained. A cylindrical ring 56 is secured to the plate 50 to act as a dam for inhibiting separated water from running downwardly into the central opening 54 and drainage means 60 is provided through which the separated water is returned from the plate 50. Horizontally-disposed passageways 46 are provided in each cylindrical member 44 through which, in use, water from the rotating flow of water/steam passes. In operation, feedwater enters the separator 10 through an inlet 14 to be discharged between an inner shroud 16 and the outer shell of the separator 10. The feedwater is then heated by a heating fluid which flows from an inlet manifold 20 through tubes 24 and exits through an outlet manifold 22. The steam generated is dried in the manner described above and exits through an outlet 32.

Title: Improvements in and relating to binary information transmission systems
IPC: H04L25/48
Filed: 1966-09-16
Abstract: 1,146,728. Data transmission systems. TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES. 16 Sept., 1966 [20 Sept., 1965], No. 41426/66. Heading H4P. Binary data is converted to a three level code (+1, 0, -1) prior to transmission. The transmitted signal has a frequency spectrum containing no frequency component at 1/2T, where T is the bit duration, so permitting a bit rate clock signal to be added to the signal without affecting the data. The conversion takes place according to the following rules: (i) each 0 bit is sent as a 0-level signal of the same duration, (ii) each 1 bit is sent as a + 1 or - 1 level signal of the same duration, (iii) a group of one or more 1 bits separated from another group by an odd number of 0 bits is sent with polarity inverse to that of the other group, (iv) if groups of 1 bits are separated by an even number of 0 bits and if the total number of 1 bits up to the end of the first of these groups is for example even, the groups are sent with the same polarity. A first converter, Fig. 3 (not shown), for use with a single transmission channel, and a second converter, Fig. 5 (not shown), for use with two channels are described, each channel of the latter operating at half bit rate. Transmission errors can be detected at the receiver by an arrangement, Fig. 7 (not shown), in which it is determined (i) that no + 1 signal is contiguous a - 1 signal, (ii) that a group of - 1 signals followed by a group of + 1 signals is separated by an odd number of zero signals and vice versa, (iii) that a group of + 1 signals or of - 1 signals followed by an even number of 0 signals is followed by a group of + 1 or of - 1 signals depending on the total number of  1 bits up to the end of the earlier group.

Abstract: 1483624 Extruding oriented cartridge case CANADIAN INDUSTRIES Ltd 26 Sept 1974 [28 Sept 1973] 41875/74 Heading B5A In the production of a biaxially oriented  polyolefinic material shotgun cartridge casing having a partially closed head end, a heated tubular blank 5 of the material, Fig. 1, is displaced upon a reciprocating mandrel 3 through an opening 7 into one end of an open ended die cavity 2, and a ram 6 then advances into the cavity through an opening 8 at its other end to circumferentially expand the blank 5 around an enlarged portion 4 of the' mandrel 3, Fig. 3, and extrude a portion of the blank through the opening 7, whilst simultaneously moulding the head by compression of the remainder of the blank 5 against the mandrel portion 4. After retraction of the ram 6 and further advancement of the mandrel 3 to displace the formed casing through the opening 8, Fig. 5, the mandrel is retracted to its Fig. 1 position as the casing is stripped therefrom by a stripper means 9 around the opening 8. The blanks which may be extruded, or injection moulded, are preheated, e.g. in a lubricant bath, to a temperature of between 80 and 240 F., but below the crystalline melting point of the material which is preferably high density polyethylene, polypropylene, or a mixture thereof. For high density polyethylene, the material and the die are maintained at 130 to 170 F.  The opening 7 may be notched to define a ribbed exterior surface on the casing. The mandrel may be modified to provide in the casing a tapering wall thickness, intermediate the head end and a tubular wall of constant thickness and thereby minimize shrinkage of the head end. The die casing may be cylindrical or may taper towards the opening 7.

Title: Process for the production of fluorine-containing organic compounds
IPC: C07C17/35
Filed: 1960-12-22
Abstract: Sulphur dioxide is produced by the thermal decomposition of a compound FSOOR where R is an organic radical (see Group IV(b)). In a competing reaction, SOF2 may be formed.  The reactions involved are: FSOOR=SO2+RF 2FSOOR=SOF2+OS(OR)2ALSO:Organic fluorides RF are prepared by subjecting a fluorosulphonic ester FSOOR (where R is an organic radical) to thermal decomposition at a temperature favouring the production of the compound RF, e.g. 100 DEG C.-300 DEG C.  The reaction involved is FSOOR=RF+SO2 and may be accompanied by the disproportionation. 2FSOOR=SOF2+OS(OR)2 Specified values of R are methyl, ethyl, propyl, butyl, octyl, nonyl, b -methoxyethyl and a -carbethoxyethyl.  Electron donors such as tertiary organic amines are advantageously present.  In their absence or in the presence of electron acceptors such as BF3, AlCl3, ZnCl2 and SnCl2, the compounds RF may be decomposed into HF and the corresponding olefines.  The various reaction products may undergo isomerisation during the process.  In examples, n-butyl fluorosulphinate produced 1-butyl-fluoride, 2-butyl fluoride and butenes, as well as OS(OC4H9)2; b -methoxyethyl fluorosulphinate produced b -fluoroethyl methyl ether, methyl fluoride and OS(OCH2CH2OCH3)2; and a -carbethoxyethyl fluorosulphinate produced ethyl a -fluoropropionate, ethyl fluoride and OS(OCH(CH3)COOC2H5)2  The fluorosulphinic acid esters may be prepared by fluorination of the corresponding chlorosulphinic acid esters with KSO2F.

A commutator motor of the type in which the speed is regulated by shifting the brush gear, is characterized in that the brushes are shifted by rotating a quill which also operates a friction brake. A quill 12 carrying brushes 16 is rotatably mounted on driving shaft 20 and has at one end an oblique slot 28 which engages with an pin 27 on a brake body 26. The quill is rotated by means of arm 17 and is biased into the minimum speed position by means of spring 25. In this position, the pin and slot cause the brake body 26 to engage with the brake drum 30, and an arm 31 operates a switch 33 to disconnect the current supply to the motor. Movement of the arm 17, rotating the brushes towards the maximum speed position, connects the current supply and causes the brake body 26 to move axially disengaging from the drum 30. External connections to the brushes 16 is made via further brushes 21 mounted on the fixed body of the motor. Instead of a pin-andslot link, a ratchet may be used, Fig. 3 (not shown).
