Title: Improvements in vapour generating and superheating units in ship propulsion power plant
Inventor: HUTCHINGS EDWARD GEORGE
IPC: F22B21/34
Filed: 1965-03-15
Abstract: 1,140,036. Controlling steam temperature in boilers. BABCOCK & WILCOX Ltd. 15 March, 1966 [15 March, 1965], No. 10925/65. Heading F4A. An oil fired marine steam boiler comprises a furnace chamber (1, Fig. 1, not shown) lined with evaporating tubes, and parallel upright evaporating tube lined convection passes 3, 4, the gas flows through which are controlled by dampers 48, 49 respectively. The pass 3 houses an intermediate superheater section 51, a final superheating section 61 and an economizer section 64, whilst the pass 4 houses an initial superheating section 66 and a reheat section 67. A steam conduit 73 containing an attemperator 74, which is in the form of an indirect heat exchanger located in the boiler drum (Fig. 3, not shown) or in a vessel in contact therewith, connects the intermediate and final superheating sections. A further indirect contact or a regulatable spray type attemperator may be located after the final superheater section to control the final degree of superheat. Alternatively (Fig. 4, not shown) a third parallel upflow damper controlled by pass (101) containing economizer or evaporator tubes (103) may be used to automatically regulate the degree of superheat. In other modifications the intermediate superheater section may be positioned in the first gas pass downstream of the final superheater section (Fig. 5, not shown) or the positions of the initial and the intermediate superheater sections may be interchanged, with or without the initial superheater section being situated downstream of the final superheater section. In all modifications having the initial superheater section in the pass 3 the attemperator 74 may be located between the initial and the intermediate superheater sections or between the intermediate and the final superheating sections. Additional economizer, or reheater surfaces may be located in a common pass downstream of the parallel gas passes. The steam flow through the superheating sections may be co-current or counter-current to the flow of gases from the furnace chamber. The location of the initial or intermediate section of the superheater upstream in the same gas pass as the reheater section protects the tubes of the latter from overheating when with the ship going astern and no reheat being required, the dampers 49 are closed to prevent gas flow through the pass 4.

Title: Heat exchangers
IPC: F28F1/12
Filed: 1978-03-20
Abstract: The wire meshes (2a'') of the coil, which is arranged in the shape of a helix on the support tube (1), are supported against one another by a support wire (3) which is bound at a spacing around the support tube (1) with the same pitch as that of the coil. The wire meshes (2a'') each have an outer web, these webs being situated in parallel and arranged at a spacing from the support tube (1) on a cylindrical surface coaxial to the latter. The wire meshes (2a'') of adjacent coil turns overlap one another at least to the extent that the support wire (3) joins all the outer webs of the wire meshes (2a'') of adjacent coil turns to one another. As a result, the wire coil is strengthened such that it can withstand all the stresses occurring during production and use of the heat exchanger. <IMAGE>
Patent GB-724119-A (GB)
Title: Improvements relating to the treatment of sulphur-containing materials from gas purification processes
IPC: C01B17/033
Filed: 1952-05-01
Abstract: Sulphur is recovered from sulphur-bearing materials, especially spent oxides from coal gas purifiers by extracting the sulphur-bearing materials with a hydrocarbon solvent boiling within the range 100 to 160 DEG C. for example xylene and toluene, cooling the solvent to cause it to deposit the extracted sulphur, freeing the deposited sulphur from solvent by passing a stream of purified coal gas through it, and passing the coal gas to a benzole extraction plant for the recovery of the solvent.  The extracted material may be freed from solvent by passing coal gas, not necessarily purified, through it and recovering the solvent from the gas in a benzole extraction plant. The cooled solvent may be reheated and recirculated, a portion being drawn off continuously for distillation to prevent accumulation of tarry matter in the solution.  The distillate may be used for washing the extracted sulphur, and the low grade sulphur residue may be burnt directly in an acid making bath, or purified by washing with limited amounts of cold xylene.

Title: Chemically crosslinked poly-phenylene sulfides
IPC: C08G75/18
Filed: 1964-03-16
Abstract: Linear polyphenylene sulphides and sulphoxides are halogenated with chlorine, bromine or iodine, and the halogenated polymers are reacted with divalent sulphur-yielding material to obtain cross-linked polymers.  The halogenation may be carried out at - 40 DEG  to 200 DEG  C. the halogen atoms being attached to the aromatic nuclei and the product preferably having at least two halogen atoms for each chain.  The halogenated polymers may be cross-linked by reaction with alkali metal, alkaline earth metal or transition metal sulphides at 150 DEG  to 350 DEG  C., either in amounts sufficient to react with all the halogen atoms, or in less than equivalent amounts, in which case the polymer contains residual halogen atoms.  In examples, linear phenylene sulphide and sulphoxide polymers are brominated and then cross-linked by reaction with sodium sulphide.

Title: Improvements in or relating to tipping casting machines for casting flat stereotype plates
IPC: B41D3/00
Filed: 1936-04-17
Abstract: 464,535. Casting stereotypes. POLTER, H. April 17, 1936, No. 11057. [Class 100 (ii)] In a, machine for casting flat stereotypes of the kind in which the mould and melting- pot are tilted for casting purposes, the matrix clamp and the part of the lower plate of the mould and the edge of the pot are constructed with thin walls and stiffening-ribs, and the hollow spaces are filled with heat-insulating material so as to prevent premature cooling of the plate at this point. The melting-pot 9 is carried by a plate 1 mounted on pivots 2 and formed with an aperture 10 for the passage of molten metal and a recess for the reception of the matrix. The matrix is held in place by an angle-bar 19 secured to a member formed by two box-like elements 15, 16 filled with a heat-insulating material such as asbestos or kieselguhr. The upper element is formed with thin walls and stiffening ribs 18, and the member is secured with the interposition of a heat-insulating plate 20, to a bar 21 carried by pivoted arms 12 and mounted in a recess in the plate 1. The bar 21 is formed with a slight longitudinal concavity on the upper surface, but the heat of the molten metal causes the element 16 and clip 19 to expand and lie flat. The part 24 of the plate 1 lying between the aperture 10 and the matrix clip is also formed with thin walls strengthened by ribs 25 and filled with heatinsulating material. The parts are so arranged that the heating-gases for the pot pass over the parts of the plate 1 adjacent to the matrix clip; alternatively, independently controlled electric heating-elements are provided. The upper plate 7 of the mould is secured to the plate 1 by means of a hinge 4, 5, 6, the pivot 4 being arranged slightly above the surface of the plate 1 to facilitate adjustment for the thickness of the plate to be cast. The weight of the upper plate is partly counterbalanced by a weight or an adjustable spring 36 connected to a lever 31 pivoted on the plate 1 and engaging a pin 33 mounted on the plate 7 between the centre of gravity line and the free end of the plate.

Title: Tone arm-operated electrical switching means for gramophones and like apparatus
IPC: G11B17/02
Filed: 1946-04-12
Abstract: 611,327. Gramophones. COMMUNICATIONS PATENTS, Ltd., and LEARNEY, L. P. April 12, 1946, No. 11306. [Class 40 (ii)] [Also in Group XXXVII] A snap-switch for starting and stopping the motor of a gramophone turntable, is operated by pivotal movement of the tone arm of the gramophone. The tone arm 6, pivoted at 10, has a pin-and-slot connection 30, 33 with a cam 21 also pivoted at 10. Rotation of the arm 6 in the direction of the arrow, Fig. 2, causes the edge 32 of the slot 33 to engage the pin 30 and so rotate the cam 21, which by engaging a roller 29 on a contact-carrying spring 23 moves a contact 27 outwards. The cam 21 also rotates a second cam 20, also pivoted at 10, through a pin-and-slot connection 34, 35, thereby stressing a contact-carrying spring 22 by means of a roller 28, until the roller rides off the edge 37 of the cam to close the contacts rapidly. When the arm 6 is rotated clockwise towards the centre of a record, the cam 21 is eventually rotated clockwise until the roller 29 rides off the edge 36 thereof, to release the contact 27 and open the circuit, the contactspring 23 engaging a hump 39 on the cam 20 restoring the parts to the Fig. 4 position. The switch may alternatively operate a brake for the turntable and may also control a muting circuit of an associated amplifier. The switch parts are mounted on a base 13 adjustably carried by the base-board of the gramophone.

Abstract: 187,253. Thornycroft & Co., Ltd., J. I., and Mackie, R. April 19, 1921. Nozzles for producing whirling sprays.- A liquid-fuel or other sprayer, of the type in which liquid is supplied to a hollow body under pressure and is caused to issue in a finelydivided state from a whirling-chamber having a number of supply conduits adapted to be opened or closed successively, comprises a body part i fitted with a cap f formed with a discharge orifice g and a rotatable spindle n carrying a key m engaging with a sleeve b which has an enlarged part c formed with longitudinal grooves d communicating through tangential grooves e with a whirling-chamber a. A transverse wall h in the body part i is formed with a series of gaps j of different circumferential lengths arranged so that by rotating the spindle n all, none, or any number of the grooves d may be placed in communication therewith thus regulating the fuel discharge. The spindle n may be threaded into the body part i so that regulation of the fuel discharge will vary the capacity of the whirling-chamber proportionately. A spring locking-bolt t on the spindle n may engage with notches in a segment s in the positions in which a definite number of grooves are unmasked. The Provisional Specification states that, alternatively, the fuel regulation may be effected by moving a masking-member in relation to a stationary grooves member.

Title: Vacuum mechanism for paper making machines
IPC: D21G9/00
Filed: 1936-04-21
Abstract: 463,904. Valves. BROUGHTON, A. E. April 21, 1936, No. 11394. [Class 135] [Also in Group VIII] The suction apparatus of papermaking machines includes automatic valves V, Fig. 1, which shut off suction from a machine when the suction in a box 9 gives out, as on pulp web rupture, and automatic control of the suction during operation, by valves 27. The valve stem 27a of the valve 27 screws adjustably into a sleeve 31 sliding in a piston 30 in a cylinder 29, the sleeve and piston being normally held in the positions shown, by springs 38, 35 respectively. If suction in a box 9 becomes too high, atmospheric pressure forces the piston 30 upwards to close the valve 27, further upward movement opening an annular passage 30b which allows air to enter and reduce the suction. The degree of suction is adjusted by screwing, e.g. through gears &c., the sleeve 31 on the valve stem 27a. The valve V which is somewhat similar to the valve 27, but works oppositely, closes when suction of the couch roll 11, to the pipe 19 of which its cylinder is connected, is substantially reduced. Further, the valve V has no spring 38 or annular opening 30c, the adjustable sleeve being held axially in the piston.
