Abstract: 666,939. Automatic temperature alarms. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 21, 1949. [Nov. 26, 1948] No. 29732/49. Class 118 (i). [Also in Group XIX] In a temperature alarm in which at a predetermined temperature the air in a bellows expands to actuate a pivoted arm which moves a switch arm to open or close an alarm circuit, the pivoted arm engages the switch arm to move it into one position only after a predetermined travel in either of its two directions of movement. Fig. 3 shows. an alarm which indicates when a, pre-determined temperature has been exceeded in a freezing cabinet. The bellows 12 is normally compressed by the plate 14 and spring 13 to a pre-determined extent dependent on the setting of knob 16. The bellows is in contact with the freezing cabinet via a tube and a thermostatic bulb associated with the inner lining of the cabinet Fig. 1 (not shown) so that as the temperature inside the cabinet increases the bellows expands and the arm 18 which is pivoted at 19 moves 'in an anti-clockwise direction. This movement continues until when a pre-determined temperature has been reached the ear 42 on arm 18 engages the crank arm 33 which is fixed to the switch arm 21, the crank arm which is pivoted at 29 is then rotated in an anti-clockwise direction against the spring 38 to break the contact 20, 22 as shown in Fig. 6. The circuit between leads 10 and 11 is thus broken and an alarm lamp is extinguished, Fig. 2 (not shown). On failure of the bellows or contraction of the air contained therein, arm 18 moves in a clockwise direction until after a pre-determined movement ear 41 makes.contact with crank arm 32 to rotate the switch arm 26 in tnanti-clockwise direction until the contact 20, 22 is broken and the alarm lamp is extinguished.
Patent GB-634135-A (GB)
Title: Improvements in or relating to fuel oils for gas turbine engines
IPC: C10G21/14
Filed: 1947-11-07
Abstract: A petroleum residue fraction containing vanadium in elemental or combined form is rendered suitable for use as a fuel for gas turbine engines by a process which comprises intimately mixing it with a solvent consisting of one or more paraffin hydrocarbons having 3-7 carbon atoms per molecule (the solvent containing not more than 0.5 per cent by weight of aromatics and being substantially free from naphthenes) and thereafter separating the solution so obtained from the material insoluble in the solvent. The solvent may be stripped from the solution and recycled for the treatment of fresh feed.  The solvent may be normal hexane, normal heptane, mixtures thereof, or mixtures of paraffin hydrocarbons containing at least 50 per cent by weight of normal heptane and/or hexane.  The vanadium content of the petroleum residue fraction before treatment may be at least 0.02-0.03 per cent by weight and the fraction may constitute not more than 30 per cent by volume of the crude petroleum from which it was derived. The amount of solvent used may be at least five times and preferably about eight times the volume of residual petroleum fuel treated.  The latter after treatment may be blended with other fuels.  In an example, a 25.2 per cent by volume residue fraction derived from a Middle East crude petroleum oil and having a vanadium content of 0.0307 per cent by weight is treated with 8 times its volume of propane in a countercurrent tower operated at 150 DEG  F. tower top and 110 DEG  F. tower base.  The treated residue constitutes 36 per cent by weight of the feedstock and contains no vanadium.  The deposition of scale on the blades of gas turbines by fuels treated according to the invention is said to be eliminated or greatly reduced.

Title: An improvement in or relating to the treatment of textiles, skins, furs and like materials and substances
IPC: D06L3/12
Filed: 1948-11-17
Abstract: The appearance of textile and like materials including skins and furs, whether dyed or not, is improved by treating them with a blue-fluorescent compound which is a substituted dihydrocollidine of the general formula <FORM:0722791/IV (c)/1> in which R1 and R2 are carbalkoxy, carbaralkoxy, or N-phenyl-(or substituted phenyl)-carbamido groups and R3 is a methyl, ethyl or aryl group. The compounds may be employed as aqueous dispersions or they may be sufficiently soluble in water, particularly hot water, to be used in aqueous solution.  They may be used alone or in conjunction with the normal hydrosulphite or peroxide baths when used for bleaching.  When applied to dyed materials they improve the brightness of the colour. In examples, (1), (2) and (3) bleached wool yarn and woollen piece goods are treated with the diethyl ester of dihydrocollidine dicarboxylic acid in the presence of formic acid; (4) wool is treated, during or after bleaching with a hydrosulphite and in the presence of formic acid, with a solution of the whitening agent above; (5) wool is treated as in (4) after bleaching in a hydrogen peroxide bleach; (6) wool is dyed in a pastel shade with Alizarine Brilliant Blue B and aftertreated with the whitening agent above or the whitening agent is added to the dyebath; (7) dressed lambskin is bleached with a hydrosulphite bleach and then treated with the whitening agent above; (8) bleached rabbit skins or fur are treated with the whitening agent in presence of formic acid; (9) wool is treated with the whitening agent in the presence of formic acid; (10 to (13) nylon and cellulose acetate are similarly treated with or without the formic acid; and (14) cotton is treated with the whitening agent in the presence of Glaubers salt.ALSO:2,4,6 - Trimethyl - 3,5 - di - N - phenyl - carbamido - 1,4 - dihydropyridine is prepared by heating together acetaldehyde ammonia and acetoacetanilide in alcohol.  Similarly, 2,4,6 - trimethyl - 3,5 - di(p - methoxy - N - phenyl - carbamido) - 1,4 - dihydropyridine is prepared from acetaldehyde ammonia and p-methoxy-acetoacetanilide. 2,4,6 - Trimethyl - 1,4 - di - hydropyridine - 3,5 - dicarboxylic acid methyl ethyl ester is prepared by condensing methyl acetoacetate with acetaldehyde to give ethylidene-acetoacetic methyl ester CH3CO.C(:CHCH3)COOCH3, which is then condensed with b -aminocrotonic ester.  The b -aminocrotonic ester is made by condensing ethyl acetoacetate with aqueous ammonia.

Filed: 1961-08-18
Abstract: 956,017. Letter-sorting systems. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT MIT BESCHRANKTER HAFTUNG. Aug. 18, 1961 [Aug. 18, 1960], No. 29903/61. Heading B8A. In a letter distribution system comprising a transport path 50 having branch paths diverging at switches wI, wII ..., controlled by a command store sub-division into sections I, II...., which are switchable forward in succession by the action of photo-electricallycontrolled switches L1, L2 ..., responsive to the passage of the letters, the spacing of the switches L1, L2 ..., is less than the length of the smallest letter to be transported. A control command 52 may be actuated manually or by code marks on the letter when the latter enters the path 50. The code consists in closing one or more of switches C01,C02, C03, in accordance with the normal setting of switches c11.3- cl3.3; C21.3-C23.3 ; . . . ; in the circuits of the energizing coils WBI, WBII ..., of the respective letter diverting switches WI, WII . . . Assuming a letter entering the path 50 is to be diverted by switch wII, the control command consists in closing switches c01, c03 (since C21.3 and C23.3 are normally open). When the letter interrupts light from a source 51 to close contact l1 of switch L1, a relay B1 is energized from a line 86.| Relays C11 and C13 are also energized through contacts C01, C03. Contact b 1 of relay B thus opens and de-energises relay ul. Contact U1 of the relay U1 have a delayed action, thus permitting relays c11 and c13 to be held open by holding contacts C11.1, C13.1 (connected through contacts b1) after contacts U1 have opened. Since contacts C13.3 are opened by the relay c13 the coil WBI of switch wI is not energized. When the letter passes out of the field of influence of the switch L1 and the contacts l1 thus open, relay B1 is de-energized. Contacts b1 thereby open and contacts U1 closes. The command code signal is thus removed from the sector I relay system. Relays C21 and C23 at sector II are not energized until the passage of the letter closes contacts l2 of switch L2. Switches C.21.3 and C.23.3 are then closed and switch wII is thereby operated. The switch WII will not be operated if the letter causes actuation of switch L2 before the contacts c11.2 and C13.2 are closed. The relay systems at sectors I, II may be replaced by transistor or valve circuits (Figs. 3 to 7, not shown).

[Also in Division C1]  Sponge iron is made by dehydration of waste crude FeSO 4  7H 2 O (a) in a relative dehydration furnace 2 to FeSO 4  H 2  O which passes to a hopper 3 and thence to a fluidized bed decomposition furnace 4 where it is heated to yield haematite ash and sulphurous gases. The haematite ashes pass to a fluidized bed reduction furnace 6 or a rotary furnace where they are reduced to sponge iron which may then be transferred to a cooling bed 8, magnetically up-graded and finally recovered at E. The decomposition may be carried out by combustion of a carbonaceous fuel (b) at 800‹- 1050‹C. or of a S-containing ore, and reduction at 600‹-900‹C. by direct introduction of a carbonaceous fuel. The gases leaving the reduction stage may be used to provide sensible and chemical heat for the decomposition stage. O 2  or air (c), pre-heated generally between 200‹C. -500‹C. in heat exchangers 11 and 12 by exchange with gases produced may also be used. Dehydration may be by a wet or dry process and magnetic up-grading by a wet, dry or mixed process.
