Title: Improvements in heater air conditioning ductwork
IPC: B60H1/00
Filed: 1957-10-18
Abstract: 827,428. Air conditioning vehicles. FORD MOTOR CO. Ltd. Oct. 18, 1957 [Oct. 18, 1956], No. 32640/57. Class 137. Heater air conditioning de-froster duct work for an automotive vehicle comprises an air inlet duct manually and selectively connectible to air intakes in the occupant compartment and outside, a blower for drawing air through the inlet duct, an air passage from the blower to an evaporator and a heater core, a manually adjustable damper for directing the air through the evaporator or through the heater core, a main air chamber connected by a further passage with the evaporator, a plenum chamber having an inlet compartment, a depending duct connecting the further air passage with the plenum chamber, a manually adjustable de-froster damper mounted in the plenum chamber adjacent the depending air duct and movable from a wide open position to a substantially closed position relative to said depending duct whereby the selected positioning of the de-froster damper will control the amount of air travelling through the depending air duct. Air is drawn into the system by blower 18 from conduit 13 which leads to a louvred opening 11 below the windscreen 12, or from conduit 14 which leads to a louvred opening 16 within the vehicle, the choice or proportion being manually controlled by damper 17. From blower 18 the air passes through heater coil 22 or evaporator 21 according to the position of the manually controlled damper 23. When cooling the vehicle, air passes through evaporator 21 and some goes through funnel-like opening 26 into main chamber 27 while the remainder passes through tube 24 and into the other end of chamber 27 from which it escapes into the vehicle near the windscreen through louvres 28. Some of the air passing along tube 24 enters connector duct 29 and flows into plenum chamber 32 and escapes into the vehicle through vents 33 and 34. When heating and demisting, air passes through heater coil 22 and thence directly into plenum chamber 32 and out of vents 33 and 34. A portion of the heated air passes up through connector duct 29 into tube 24, thence to the extremities of chamber 27 and escapes below the windscreen through louvres 28.. A manually controlled flap valve 37 is so designed that in both of the positions shown it is capable of allowing part of the air past it, air passing round its sides when in the almost vertical position and it being prevented from closing completely the mouth of duct 29 by a resilient bumber attached to the plenum chamber.

In a stop-on-signal radio receiver depression of a push-button 11 initiates energization of a relay 10 and tuning motor 12, by means of the anode current of audio output valve 1, the relay being held energized by the changeover of contact 10b which also serves to mute the loudspeaker 2, this condition being maintained until a negative signal derived from the received carrier e.g. an A.G.C. signal or a signal derived from the discriminator in an F.M. receiver) and applied via terminal 14 and contact 10a to the control grid of output valve 1 achieves such a magnitude as to prevent the flow of current through the valve whereupon the relay 10 drops out and energization of motor 12 ceases. In the circuit illustrated, during energization of relay 10 contact 10c opens and contact 10d closes to convert the two-stage amplifier comprising valves 1 and 17 into a reciprocally coupled trigger pair which undergoes a sudden change of state, resulting in valve 1 being switched off, when the negative voltage applied to its control grid exceeds a predetermined value. Alternatively a positive voltage derived from the received carrier may be applied to the control grid of valve 17. During normal reception, the grid-bias for valve 17 is taken from across resistor 16 of potential divider 15, 16 connected in parallel with resistor-capacitor biasing circuit 5, 6 for the output valve 1.

Title: Improvements in or relating to composite titanium pigments
IPC: C09C1/00
Filed: 1932-11-18
Abstract: Composite titanium pigments are made by mixing mechanically a hydrated titanium compound, precipitated from an acid solution containing titanium, with an inert extender, and treating the titanium compound, either before or after mixing with the extender with a reagent to neutralize, partly or wholly, the free acid contained therein, washing the neutralized product to remove soluble salts and finally calcining the mixture.  Neutralizing agents specified are:--barium chloride alone or mixed with caustic soda, barium hydrate, calcium carbonate or chloride, or lime.  For example, a titanium oxide pulp containing free sulphuric acid is mixed with milled natural barytes or gypsum as extender, and barium chloride solution is added.  The mixture is warmed, diluted with water, filtered and the resulting precipitate is washed and calcined at 700 to 1100 DEG  C.  Other inert extenders specified are china clay, alumina, silica, or blanc fixe.  Before calcining the mixture, there may be added a small amount of phosphoric acid or a fusible salt such as calcium or baium phosphate, or compounds may be added to the titanium compound to form such fusible salts with the free acid. Specifications 149,316, [Class 95], and 374,420 are referred to.

Patent GB-985297-A (GB)
Title: Process for preparing aromatic diisothiocyanates
IPC: A61K31/26
Filed: 1961-09-13
Abstract: Aromatic diisothiocyanates are prepared by dissolving an aromatic primary diamine or a substituted aromatic primary diamine in dimethylformamide, adding to the solution obtained ammonia and carbon disulphide, subjecting the ammonium-bis-dithiocarbamate (or a salt obtained by reacting said salt with another base) thus formed to the action of an alkali metal chlorite and recrystallizing the crude product so obtained from formic acid methyl ester.  The aromatic diamines used as the starting material may contain one or more rings, the individual rings being linked directly to one another or through alkylene groups, or being fused, e.g. phenylene and naphthylene diamines, benzidines and diamino-diphenyl methanes. The abovementioned compounds may be substituted by halogen atoms or alkoxy and/or alkyl groups preferably containing from 1 to 4 carbon atoms.  The reaction between the diamine and the ammonia and carbon disulphide is preferably carried out at low temperatures, e.g. room temperature, and using 2 to 6 mols. of ammonia and 2 to 3 mols. of carbon disulphide per mol. of diamine.  The conversion of the bis-dithiocarbamates into diisothiocyanates may be carried out by stirring an aqueous solution of the alkali metal chlorite into an aqueous solution of the bisdithiocarbamate. Preferably the chlorite solution is of 20% to 40% strength and 2 to 3 mols. of chlorite per mol. of bis-dithiocarbamate are used.  The reaction temperature is advantageously in the range - 15 to + 30 DEG  C. In the examples the following compounds are prepared: phenylene - 1,4 - diisothiocyanate, phenylene - 1,3 - diisothiocyanate, 2 - chloro phenylene - 1,4 - diisothiocyanate, 2 - methoxy-phenylene - 1,4 - diisothiocyanate, 2,6 - dichlorophenylene - 1,4 - diisothiocyante, 2,5 - dimethylphenylene - 1,4 - diisothiocyanate, naphthylene - 1,4 - diisothiocyanate and diphenylene-4,41-diisothiocyanate.

Abstract: Converted starch products such as dextrin are obtained from cereals by adding to milled cereals containing sufficient moisture normally to cause the non-starchy components to gel a small proportion of a gel-inhibiting of the classes of salts or addition compounds of sulphurous acid, its derivatives by reduction or organic addition compounds, or hydrogen sulphide and its derivatives, then adding a known catalytic conversion accelerator and heating the mixture till the desired conversion is obtained. Gel-inhibiting agents mentioned are sodium bisulphite, metabisulphites or pyrosulphites, sodium hydrosulphite, sodium sulphoxylate formaldehyde, sodium and potassium sulphides, ammonium polysulphide and sodium xanthate.  In an example, sodium bisulphite is mixed with flour, an acid or acid salt added in excess of that required to react with the sodium bisulphite, the excess acting as a catalyser and the mixture heated.  The amount of liquid present should not be such that the mass is brought to a liquid condition.
