IPC: F23M9/00
Filed: 1975-07-25
Abstract: 1509898 Burners HOTWORK INTER. NATIONAL Ltd 25 July 1975 [1 July 1974] 29180/74 Heading F4T A method of changing the direction of flow of the products of combustion leaving a burner comprises, locating a burner block 1 having a convex surface 4 adjacent the discharge end of the burner along which the projected products of combustion are caused to flow. The block may be a quarl whose central passage 2 may be of circular, or elongated cross-section. The passage is reduced at 3 and is reduced further at 6, 7, so that dimension b is equal to dimension a/4. The products of combustion (indicated by full-line arrows), pass to surface 4, and due to the restriction between the surface and lip 6, an injector effect entrains some of the furnace atmosphere (indicated by broken-line arrows), and the flow is deflected through 90 degrees. Arrangements of such burners incorporated in heating circular and heat treatment furnaces are described, Figs. 2 and 3 (not shown). It is stated that the burner can be inserted in the roof of a beehive kiln, or in the wall of a vertical furnace.

Abstract: 905,671. Casting processes; making compound rods or tubes; welding by fusion or pressure. BIRMINGHAM SMALL ARMS CO. Ltd. Aug. 18, 1960 [Aug. 27, 1959], No. 29269/59. Drawings to Specification. Classes 83 (1), 83 (2) and 83 (4). A transition piece for joining together, e.g. by fusion or pressure-welding, two metal pieces or articles of different characteristics is made by melting in immediate succession in a consumable-electrode arc-furnace at least two electrodes of suitable different metal compositions. The result is a casting with a transition zone of intermediate characteristics between the two ends. For joining together austenitic steel and ferritic steel, one electrode would be of austenitic steel and the other of ferritic steel, and they may be joined end to end as by welding to form a single composite electrode. The casting may be further treated as by forging and machining, and for joining pipes &c. may be made tubular by hot-piercing, and drawing out &c., or by machining.

Title: Delay-action mechanism
IPC: G05G7/14
Filed: 1949-11-16
Abstract: 677,270. Spring controlled delay-action mechanism. ROTHERHAM & SONS, Ltd.. and OLIVER, C. S. Sept. 21, 1950 [Nov. 16, 1949], No. 29298/49. Classes 10 and 57 In a delay-action mechanism of the kind having a driving element for a time-delay mechanism which is moved in the operating direction at a speed depending upon the operation of the time-delay mechanism the driving element is moved in the operating direction by a spring upon the release of a catch (to be actuated by a solenoid or in other ways) which is biassed in the engaging direction by a spring stronger than the actuating spring for the driving' element. In the construction shown the time-delay mechanism 13 is driven by a gear train through a free wheel the first pinion 12 of the gear train engaging with rack teeth formed on a driving element 11. This element is biassed in an operating direction (i.e. to the right in the figures) by an actuating spring 14 reacting between the casing 15 housing the train and mechanism 13 and an abutment 16 on the free end of the element. The element is prevented from moving to the right under the influence of spring 14 by a catch 19 engaging the abutment 16 the catch being mounted on a slidable member 20 which is biassed to the left by a spring 21 which is stronger than the spring 14 and which reacts between the casing 15 and the catch. A loop 22 connected to the member 20 is joined to a solenoid or. other means and on the pull from the solenoid or other means moving the member 20 to the right the spring 14 actuates the element 11, gear train and time-delay mechanism. When the timedelay period is over the rack reaches a portion of the pinion 12 where there are no teeth and the element 11 is thereby released to complete its final movement still under the bias of the spring 14. A projection 17 fast with the element 11 and operating in a slot in the casing limits the extent of movement of the element. Similarly a stop 23 on the slidable member 20 restricts the movement of the latter in the operating direction. De-energization of the solenoid enables the spring 21 to return'the catch into engagement with the element 11 and the latter into its inoperative position. Supporting trunnions 27 are carried by flanges 28 which are fast with the plates 24, 24, of the casing.

[Class 98 (ii).] Colloid reliefs are made by treating a colloid layer in which there has been locally formed, with avoidance of hardening, a heavy metal compound by reaction between a heavy metal compound and the material of a photographic image in the layer, with a swelling agent or solvent for the colloid (other than an alkali or an acid), under such conditions that the pure colloid is dissolved whilst the parts of the layer containing the heavy metal compound remain unaffected. Reference is made to Specification 366,552, in which the parts of a colloid layer containing heavy metal salt are dissolved by alkali or acid. Four examples are given for treating silver prints and kinematograph films. The treatments include bleaching baths of mercury chloride and potassium bromide, and copper sulphate and potassium bromide ; and also a solution of potassium permanganate and sulphuric acid to dissolve out the silver picture. For removing the colloid where no formed heavy metal salt is present a saturated aqueous solution of potassium bromide, potassium thiocyanate, chloral hydrate and water at 35‹ C. may be used. The reliefs may be obtained from reflex prints, whole-tone or half-tone images ; the exposure may be through the supports ; and pigmented or coloured emulsions may be used. The reliefs obtained may be dyed, used for etching resists, or for hydrotype printing forms.

Title: Process for carbon dioxide absorption
IPC: C10K1/16
Filed: 1959-09-01
Abstract: CO2 is recovered from gaseous mixtures containing it together with one or more other components including natural gas components, H2, O2, N2H2S, COS, SO2 and moisture by absorption at super atmospheric pressure in a <PICT:0891551/III/1> countercurrent stream of butoxy diethylene glycol acetate or methoxy triethylene glycol acetate or mixtures thereof, reduction of the pressure to flash off CO2 and subsequent recycling of the acetate solution for further absorption of CO2.  A gaseous mixture containing CO2 pressurized under a CO2 partial pressure of 40-600 p.s.i. a. enters the base of a packed or tray filled absorption tower 11 through line 10 and flows in countercurrent to a descending stream of acetate solvent cycling in the system and entering the tower through line 12. Undissolved gases are vented through line 13.  Rich acetate solution containing absorbed CO2 leaves the base of the absorption tower through line 14, cooler 15 which removes excess heat of solutions, pressure reduction valve 17 and line 20 to enter flash-off chamber 21.  Valve 17 may be a turbine or other power recovery device and may be caused to power pump 18 in recycle line 19 with the aid of auxiallary pump 28. Flash-off chamber 21 is divided into two zones 22 and 24.  In zone 22 the pressure is partially reduced, CO2 and other desorbed components being vented through 23.  Partially regenerated acetate solution passing to zone 24 by line 25 is pressure reduced to about atmospheric pressure and desorbed CO2 vented through 26.  Lean acetate solution may be recycled direct to the absorption tower by pump 18 and lines 27 and 12 or some or all be subjected to gas stripping in tower 30 to remove final traces of CO2 and other components.  Tower 30 receives stripping gas, e.g. air or other inert gases, through line 31, usually at the rate of 1-5 S.C.F./gallon of acetate solution, and vents stripping gas, CO2 and other components through line 32, lean acetate solution being fed back through lines 33 and 12 to absorption tower 11.  CO2 and the major portion of other components vented from zone 22 in flash-off chamber 21 may be recycled to the absorption tower or be used separately as a fuel.
