Title: Apparatus for and method of refining an iron base melt
IPC: C21C5/34
Filed: 1973-07-27
Abstract: 1456977 Metallurgical converters USS ENGS & CONSULTANTS Inc 27 July 1973 [27 July 1972 24 Nov 1972] 35875/73 Heading F4B [Also in Division C7]  Apparatus for refining iron by bottomblowing with a stream of gas in which a particulate additive may be suspended includes a gas supply system in which a valve controlling flow rate from the supply source is actuated in response to a flow sensor to compensate for variations resulting from introduction of the particulate material and to maintain a constant flow rate at the tuyere. Additionally a gas pressure sensor at the tuyere may be coupled to the control unit to ensure that the pressure is always adequate to prevent entry of metal into the tuyere. As particularly described, converter 10 is blown with streams of oxygen and a sheathing hydrocarbon gas, lime being dispensed into the oxygen stream when required from hoppers (48, 48<SP>1</SP>). Flow control valve 28 is actuated by control unit 54 which receives signals from flow meter 26 and pressure sensor 64, while the desired flow rate is set on potentiometer 60. A similar system 54<SP>1</SP> may be used to control the flow of nitrogen which replaces oxygen during certain stages of the cycle. The invention may also be applied to a converter additionally having tuyeres for side-blowing, to an arc or openhearth furnace, or to a mixer. The construction of the furnaces of Figs. 2, 3, 4, 5, 6 is identical with that in a case by the same Application which was only recently accepted.

Abstract: 1286408 Polyurethane-bitumen composition NAPHTACHIMIE 24 July 1970 [25 July 1969] 36044/70 Headings C3N and C3R [Also in Division H2] A composition comprises a petroleum bitumen (I) and a polyurethane (II) in a wt. ratio I: II of 0À2 to 2:1. II is prepared in the presence of I from a mixture of 20-80% by wt. of a polyether polyol with a hydroxyl functionality of at least 5 and M.W. 600-6000 and correspondingly from 80-20% by wt. of a polyether polyol with a maximum hydroxyl functionality of 3 and M.W. 200-4000 together with sufficient polyisocyanate to provide a ratio of isocyanate to hydroxyl groups of 0À8-1À2. The composition may also comprise a mineral filler, e.g. tale, kaolin, asbestos, barytes or dolomite, an organic filler and/or petroleum oils. The composition may be prepared by first mixing the polyols with the bitumen and optionally a catalyst and in a second stage adding polyisocyanate. Alternatively, some of the polyols may be mixed with the bitumen and optionally a catalyst and in a second stage reacted with a prepolymer obtained by reacting the remainder of the polyol with polyisocyanate. The compositions are useful in sealing joints and covers and as a filling material in the electrical industry.

Abstract: 1416350 Pantograph PIRELLI GENERAL CABLE WORKS Ltd 31 July 1973 [2 Aug 1972] 36099/72 Heading B7L A pantograph comprises a hollow radius arm 14 adapted to be pivoted to a vehicle at 16 and elevated by a bellows 18 extending between the arm and plenum dish 10, the bellows receiving pressurized air through insulators 12 which then exhausts through apertures 26 into the arm and to a head assembly 40 at the upper arm end, the relative distance between said upper arm end and a contact wire being maintained constant by control of venting apertures 60, 62, 64 for the exhausted air, closable by a vane 66 such that when a mat 50 supporting brushes 56 (see Specification 1,416,349) moves up and down on resilient bellows 52, 54 to follow the wire the upper end 74 of the vane moves with it due to a spring bias at pivot 68, the apertures being increasingly vented as the mat moves down, right-hand side of Fig. 2, and decreasingly vented as the mat moves up, left-hand side of Fig. 2, whereby the bellows expand to follow an upward movement of the mat and contract to follow a downward movement. Normally the vane occupies the position shown in dot-dash lines where only aperture 64 is vented. Exhausted air from the arm 14 enters a feed-box 48 below an aluminium honeycombed platform 46 in which the apertures are located. Some air is exhausted through the platform directly to bellows 52, 54. The platform 46 is supported by arm 43 to be maintained horizontal. A combined compressed air spring and damper 28 biases the arm 14 downwards.

Abstract: 1,106,385. Liquid level control. GARDINER, SONS & CO. Ltd. Dec. 11, 1964 [Sept. 13, 1963], No. 36180/63. Heading G1H. [Also in Division F2] A liquid level control unit is mounted adjacent a container, such as an engine sump, to control  the flow to and the level in the latter and includes a casing 1 having an inlet 2 and an outlet 3 connected to the container. Liquid from the inlet enters a float chamber within the casing via ports 35 and the interior 19 of a fixed central tubular column 18, the interior 19 communicating with the float chamber via further ports 21 in the column and ports 60 in a sleeve valve 50 connected to float 58. When the level in the chamber, and thus in the container, reaches a predetermined point the float seats shoulder 56 of valve 50 on shoulder 52 of column 18 to interrupt flow. If the container is an oil sump, the flow of oil to the chamber is prevented when the engine is running by a spring-biased valve 31 responsive to engine oil pressure admitted to port 43. In other applications valve 31 could be actuated manually, pneumatically or electrically and could be biased to a closed position. Spring-biased levers 64 connected to the foot of column 18 carry rollers 67 which co-operate with conical surface 54 on sleeve 50 to prevent vibration of the latter in the extreme positions. The container level is varied by raising or lowering casing 1 relative thereto, the casing having a slotted mounting flange 7 for this purpose. A vent and overflow passage 13 for the float chamber has a filter 14. The float is of cork, plastics or metal.

Title: Method of and apparatus for making cappelletti or ravioli

Filed: 1971-08-03
Abstract: 1350447 Pasta production G MAINO 3 Aug 1971 [12 Aug 1970] 36350/71 Heading A2B  A method of making a cappelletto, which consists of a dough casing formed by folding a sheet dough blank into two layers between which a filling is disposed, comprises forming seats at two opposite locations disposed respectively adjacent the two ends of the folded edge of the casing, and engaging into the seats respective mechanical members which then each carry out a respective swinging movement towards each other and through approximately 90‹ in opposite directions, thereby causing the corresponding portions of the. casing to slide over a smooth part of a plane which supports the cappelletto so as to pinch the portions of the casing together. The method may be carried out in the apparatus shown in Fig. 8 wherein a plane 9, smooth but with a small farrow 10 (not shown) in its upper surface., has mounted thereabove a punch 12 and mechanical members 13. The punch and mechanical members are attached to rotatable shafts 19, 20, and are vertically moveable. The profile of the punch is the same as that of the furrow so that, when the punch is lowered on to the dough casing, which is positioned on the plane 9, a corresponding furrow is impressed in the casing. The fingers 13 press into the layers 5" of the casing and immediately the fingers rotate as shown in Fig. 4. Thus, while the arcuate part 23 of the layers 5" is kept still by punch 12 and furrow 10 (not shown), the portions 24 of the casing are stretched, as indicated by the arrows in Fig. 4, until they are pinched together. A stop 11 (Fig. 5, not shown) ensures that, when the punch and mechanical members are raised from the plane the cappelletto is removed therefrom.

Abstract: 846,961. Ultrasonic wave couplings. MULLARD Ltd. Feb. 26, 1959 [Dec. 3, 1957], No. 37648/57. Class 40 (4). [Also in Group XXII] Printed circuits are soldered by a portion of molten solder locally raised from a bath with the aid of ultrasonic vibrations. A stainless steel bath 1, heated by electric elements 2, has its base formed by part of a coupling-member 4 secured to the bath at or about its nodal point and coupling a vibrating member 5, upstanding in the bath, to an electro-mechanical transducer 6. The transducer and coupler are enclosed in a housing 8 in which cooling liquid is circulated. In operation with the solder 3 in the bath molten the current supply to the winding 7 is switched on to vibrate the member 5 which results in a ridge of solder 20 and a printed circuit board 9 is transported over the ridge to solder the leads thereof to the circuit 19 on the underside of the board. The shape of member 5 is such that the ridge is confined to that part of the circuit to be treated. A number of circuit boards may be successively passed over the bath, the transducer supply being switched on each time one is to be soldered.
