Title: Improvements in mechanism for releasing bombs or other articles from aircraft
IPC: B64D1/04
Filed: 1927-01-24
Abstract: 287,671. Pearson, K. N. Jan. 24, 1927. Dropping bombs.-Relates to devices having a number of pull rods for operating separate bombdropping gears by flexible connection therewith, and consists in the provision of means for selecting one or more of these rods for operation, for setting the selected rods at "halfcock " position, for changing such selection. and for actuating the selected rods. As shown in Fig. 3, four pull rods 4 are slidably mounted in bearings 4a at the forward end of a cylinder D and are normally urged away from the cylinder by springs 4b. The ends of the rods inside the cylinder carry spring pawls 10, which bear against the periphery of a disc 8 on a shaft 6. This shaft has a pulley 7 at its rear end connected by a belt 12, Fig. 1, to a selecting wheel 13, which can be set to various positions indicated by a pointer 22. A notch 9 in the edge of the disc 8 releases a pawl 10 when set opposite the pawl; a shoulder 20 on that pawl then falls behind a disc 15 slidably fitted over the shaft 6; and if this disc is pulled back by cords 29, it drags the pawl 10 and the corresponding rod 4 with it. The cords 29 are operated through a bridge-piece 28, a cord 27, and an arm 26 by means of a handle 18. A full stroke of this handle causes the release of the bomb controlled by the particular rod 4 in operation. A short stroke of the handle into a " half-cock " notch in a sector 23 merely pulls the pawl 10 out of the disc 8; and after this, a return of the handle 18 to the starting position leaves the pawl 10 held back by the disc 8. In this way, the disc 8 may be turned to several positions and corresponding pawls 10 and rods 4 brought to " halfcock " for subsequent simultaneous full operation by a complete stroke of the handle 18. Any pawl 10 and rod 4 at "half-cock" is returned to the safe position if the notch 9 in the disc 8 is brought opposite the pawl. In a modification, a ring embraces the outward ends of the rods 4 and is carried by two diametrically opposed rods parallel to and similar to the rods 4. Another notched disc is arranged behind the disc 8 and rotates therewith. A pawl on each of the additional rods co-operates with these discs, so that in one position of the disc, called "salvo," a pull on the disc 15 is transmitted to the ring and all the rods are simultaneously operated, whereas in another position of the discs 180‹ from the first position, called "safe,"a pull on the disc 15 merely operates such rods as may have previously been set at "half-cock." In this modification, moreover, a triple pulley is fitted at the end of the shaft 7, so that it can be set from various setting wheels situated at different places on the aircraft.

Title: Improvements in or relating to the oxidation of unsaturated fatty acids
IPC: C07C51/275
Filed: 1939-01-23
Abstract: 524,163. Carboxylic acids. DU PONT DE NEMOURS & CO., E. I., and ELLINGBOE, E. K. Jan. 23, 1939, No. 2322. [Class 2 (iii)] The oxidation of unsaturated aliphatic longchain carboxylic acids to produce saturated mono- and di-carboxylic acids is effected with strong nitric acid and a vanadium catalyst at ordinary or slightly elevated temperature, such as 0-40‹C. The nitric acid should be of 80 per cent. or higher strength and should be used in the molecular ratio of 5-15 per molecule of unsaturated acid. In an example for the oxidation of oleic acid, the product is diluted with water, yielding two layers. The aqueous' layer after decolorizing is cooled to 10-0‹C. to crystallize dibasic acids (largely azelaic acid) and the mother-liquor after concentration and cooling yields more dibasic acids ; the oily layer is steam-distilled, to recover monobasic acids (principally pelargonic acid); the residue of the distillation in further treatment with nitric acid and vanadium catalyst yields some further dibasic acids and a nitrogen-containing residue. Alternatively, the original oxidation product may be neutralized with potassium carbonate, the organic acid salts being then separated by crystallization from the potassium nitrate. In another example, erucic acid is oxidized yielding brassylic acid which is insoluble in water ; the products may be separated by esterifying the mixture and fractionating the esters. For this purpose the reaction product is treated with water and the waxy material is separated and dissolved in sodium hydroxide, zinc dust being added to reduce the nitrated products and acidified with hydrochloric acid ; the insoluble material thus freed from the nitrogen compounds is washed and dried and then esterified with methanol in the presence of hydrochloric acid. The mixed esters on fractionation yield methyl pelargonate and brassylate.

Title: Improvements in and relating to signalling apparatus for use in mine shafts
IPC: B66B19/06
Filed: 1921-01-19
Abstract: 175,175. Blunt, R., and Mitchell, H. F. Jan. 19, 1921. Addition to 162,850. Order apparatus; mine signalling systems.- Relates to the mine signalling apparatus -described in the parent Specification which comprises a series of stepwise indicators actuated by solenoids, the circuits for which are closed by switches in the pit shaft. The invention consists in omitting the solenoids of one or more indicators and arranging such indicators to be raised mechanically by an adjacent indicator. Also separate solenoids may be employed for tripping each ladder or two or more ladders may be arranged to be tripped by one solenoid in addition to the tripping mechanism controlled by the winding engine. In Fig. 2, which omits the upper part of the mechanism, a small bracket 20 is shown secured to one side of the " Men riding" indicator ladder and projects into the path of a similar bracket 21 on the " Change deck" ladder, the brackets being normally one step apart. The " Change deck " indicator is operated by a switch of the type described in Specification 161,806 having a secondary circuit connected to the solenoid e<1>, which actuates the trip mechanism w<1> for the " Change deck " indicator. When it is desired to signal " Men riding," the " Change deck" indicator switch is closed three times. The first closure raises the " Change deck " ladder only, but the second and third closures raise both the ladders simultaneously through the interengagement of the brackets 20, 21. The " Men riding" indicator is retained by the pawl r, but the " Change deck" ladder may be tripped from the cancelling-switch through the solenoid e<1>. In another construction the " Operating " and " Destination " ladders are transposed. The solenoid e<1> is omitted and the solenoid e is placed centrally between the " Operating " and "Change deck" ladders. The auxiliary trip w is replaced by a short bar extending below both pawls r and adapted to trip the " Operating " and " Change deck" ladders simultaneously. A modified construction is also described for use with single deck cages. In this case the " Operating " ladder is arranged between the " Destination " and " Men riding" ladders, and a bracket on one side of the " Operating " ladder projects into the path of a similar bracket on the adjacent side of the " Men riding " ladder, the normal vertical space between the brackets being equal to two steps. To signal " Men riding," the operating-switch is closed three times and the " Men riding " ladder is raised through the interengagement of the bracket on the third closure of the switch. In this case no " Change deck " indicator is required and three indicators may be controlled by one switch.
