Title: Improvements in or relating to the burning of pyrites, or iron sulphide and the production of iron oxide
IPC: C01B17/52
Filed: 1930-06-16
Abstract: <PICT:0359478/III/1> <PICT:0359478/III/2> In roasting pyrites or ferrous sulphide by means of air in a rotary shaft, kiln or mechanical furnace, the temperature of the ferrous sulphide combustion zone is controlled by introducing a relatively cool gas consisting of sulphur dioxide and/or nitrogen.  The combustion zone is preferably maintained at 800-1000 DEG  C.  A shaft furnace 1, Fig. 1, is charge with lump pyrites at 4, air being injected at the base at one or more points 6; in the upper zone of the furnace the labile sulphur from the pyrites distills, in the lower zone combustion of ferrous sulphide takes place.  Gas comprising sulphur dioxide and nitrogen is withdrawn from the upper part of the combustion zone by a pipe 7, is cooled in a heat exchanger 8 and is forced by a pump 9 through a pipe 10 into the lower portion of the combustion zone.  The air supplied at 6 may be wholly or in part joined with the cool gas flowing through 10.  The gases leaving the shaft at 13 may be treated for the recovery of its sulphur and sulphur dioxide content or may be passed through a bed of incandescent coke to produce sulphur.  The process may be modified by introducing the cooling gas at a point slightly higher than the point of introduction of the combustion air which may be preheated preferably by heat exchange with the cooling gases.  This maintains a vigorous oxidizing condition in the lowest part of the furnace whereby last traces of sulphur are removed. According to a further modification, Fig. 3, the gases leaving the top of the furnace are passed through a cooler 14 and a precipitation vessel 15, where free sulphur is collected, the cooled gas passing to a separator 16 from which concentrated or pure sulphur dioxide is returned via pump 9 and pipe 10 to the combustion zone of the furnace.  The sulphur dioxide reacts with the ferrous sulphide to produce iron oxide and free sulphur so that the amount of free sulphur obtained is increased.  Other modifications described are the introduction of secondary air into the distillation zone to increase the proportion of sulphur dioxide obtained, and increasing the proportion of free sulphur by adding carbonaceous matter, such as coke to the charge or by introducing a reducing gas such as carbon monoxide.  Specifications 3704/87, 817/00, 10295/00, 2789/07, [all in Class 1, Acids, alkalies, &c.], 236,256, 254,691, [both in Class 1 (iii), Oxides &c., Metallic], 273,976, 279,693, [both in Class 82 (i), Metals, Extracting &c.], 340,736, and 351,825 are referred to.

Title: Improvements in or relating to electrical signalling systems
IPC: G08B17/06
Filed: 1946-06-20
Abstract: 620,158. Fire alarm systems. BATT, W. A. T. June 20, 1946, No. 18550. [Class 40 (i)] [Also in Group XXXIX] A distant alarm, e.g. for calling firemen, comprises a relay system which, when connected to a telephone line, is responsive to a special tone signal but is unresponsive to ordinary speech. Ringing current in the line L1, L2; Fig. 2, operates relay A which completes a circuit for motor M through a power transformer TP. After running for one second the motor closes contact m1 for a period of 59 seconds to energize relay B, and closes contact m4 for a period of 5 seconds to energize relay C. Relay B connects the line to transformer T1, prepares an operating circuit for relay D and maintains the circuit for motor M. Relay C applies to the line a tone derived from the power supply via condenser QD to indicate that the apparatus is ready. The operating tone produced by a signal generator is connected to the line for approximately 8 seconds and is received by a voice-operated relay VOR which completes a circuit for relay D which is slow-acting by 6 Œ2 seconds. Relay D energizes relays DD, SC and RB which operate a siren installation and a call bell system. After approximately 60 seconds from the time of the first operation of relay A the contact m1 opens to return all relays to normal. An ordinary telephone call inadvertently connected to the system fails to operate the alarm since the voice-operated relay is not operated continuously for long enough by speech to operate D. In the event of failure of the power supply a relay F prepares a circuit by which the call bell system is directly controlled by ringing current on the line.

Title: Method of and apparatus for fabricating seamless containers
IPC: B21D22/28
Filed: 1971-06-02
Abstract: 1345227 Cupping CROWN CORK & SEAL CO Inc 2 June 1971 [11 Aug 1970] 18643/71 Heading B3Q A method of ironing and sizing the side walls of a shallow sheet metal cup to form a seamless container includes ironing the side walls of the cup to reduce the thickness of and substantially increase the length of the cup side walls, sizing the side walls without substantial decrease of thickness or increase in length and subsequently ironing the walls further. The cup is made from a steel blank, in a punch and die assembly 100, 102, Fig. 2. The assembly 100 includes a member 104, which rests on the blank, and a punch 106 provided with coolant passages, the coolant serving as a lubricant if required. The assembly 102 includes a drawing die 110 and an ironing die 112, the latter having a smaller clearance with respect to the punch 106 than the die 110. The die 112 reduces or eliminates the increase in thickness of the walls towards the top of the cup produced in the initial drawing stage. Lubricant is supplied through a plurality of recesses 132, 134 in the direction of the arrows FP, the recesses 132 being flared, Fig. 2b (not shown). The cup 10 is placed on a punch 26, Fig. 3, which comprises an ironing surface 30 and an ejecting member 31 and which may be provided with coolant passages. The first die 46 is a presizing ring which slightly reduces the wall thickness and is followed by a first ironing die 48. A sizing die 50 is located close to the die 48 to ensure accurate alignment of the cup during ironing, as any misalignment would result in pieces of the cup walls being pinched off and scoring of subsequent cups. A second ironing die 52 is located at a sufficient distance from the die 48 to ensure that the cup is only engaged by one ironing die at a time so as to decrease the risk of the cup walls fracturing or the bottom separating from the side walls. A second sizing die 54 is located close to the die 52. Finally the bottom of the cup is domed by a die 38 forcing the bottom of the cup against a concave surface 36 of the punch 26 to complete the seamless container.

Title: Method and apparatus for duel resolution analysis of a scene
IPC: G01N15/14
Filed: 1977-05-04
Abstract: The sample to be analysed is examined in a first field, of low resolution, of the apparatus; if an object thus detected belongs to a specified category, for example the category of leucocytes in the case of a blood sample, it is subjected to a second analysis in a second field, of higher resolution, the low-resolution examination being nevertheless continued in order to detect the possible presence of another object. The apparatus comprises a sample holder (1) which can be moved in two directions using motors (2 and 3), and which holds a sample (4) comprising several particles (5a, 5b, 5c) of interest. An objective (6) forms an image (10) of a part (7) of the sample on a low-resolution sensor (9), and does this using a plate (6b) and an optical system (8), and an image (14) of a part (11) of the sample on a high-resolution sensor (13), and does this using a second optical system (12). The output signal from the low-resolution sensor (9) is analysed so that when a particle of interest is encountered, the sample holder is moved in order to bring the particle into the field of view of the high-resolution sensor, which allows its high-resolution analysis by a corresponding analyser (37). This method and this apparatus make it possible to analyse in detail only the objects of interest, without having to perform a detailed analysis of all the objects present. This method and this apparatus may be used for analysing blood cells, scrapings or cancer cells. <IMAGE>

Title: Union for pipes or conduits particularly for lubrication systems
IPC: F16N21/04
Filed: 1925-07-27
Abstract: 237,627. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements Tecalemit). July 26, 1924, [Convention date]. Couplings, disconnectible. - Relates to couplings for pipes &c., particularly for lubricating systems of the type wherein connection between a body member a, in communication with a pump by means of a conduit b and a nipple l on the part to be lubricated, is effected by a transverse movement which engages flanges or a ' hook ' on one member with a radial flange on the other member, each member having a central lubricant passage. Surrounding the body a is arranged a movable part c provided at its base with a hook-on flange d, while within said body is positioned a plunger e with a cup-leather washer g, attached to the part c by a rivet f. The body a is also provided internally with a valve i, having an internal T- shaped canal j normally resting upon it, and an annular leather packing k on its base adapted to surround the stem of the valve i. In operation, the flange d is hooked on the flanged nipple l and the pump operated. The consequent pressure on the body a acting on the washer g causes the body a to descend and the packing k to contact with the nipple l, which contact causes the valve i to open and put the canal j into communication with a passage h leading from the conduit b. When the lubricating is finished the internal pressure is slightly reduced to permit the unhooking of the union, whereupon the valve i automatically closes under the action of the remaining pressure. In a modification, the valve i is replaced by a spring-pressed valve. Specifications 149,609 and 211,881 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a further modification wherein the hook-on flange is solid with the body a, and said body is provided with an internal pressure member in the form of a sliding piston-like element adapted to make a sealed joint with the nipple and a spring-loaded valve for opening a delivery passage through the pressure member under influence of the internal pressure. This subject-matter does not appear in the Specification as accepted.
