Abstract: 448,736. Bomb-dropping apparatus. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., SIR W. G., and LOCKWOOD, S. W. D., Whitley, Coventry. May 7, 1935, No. 13415. [Class 9 (ii)] Relates to apparatus for dropping bombs from aircraft, of the kind in which the bomb is guided out by a radius-rod device, for example as described in Specification 419,563. According to the invention the outward movement of the radius rod 12, which is pivoted at 13, operates a cam mechanism for opening the door of the bomb receptacle and holding it open until the radius rod is again withdrawn into the receptacle. As shown, the radius rod is provided with a cam 17, which bears on a roller 19, when the rod swings out, and thereby rocks an arm 20 about its pivot 21. The arm 20 is coupled by a link 22 to a crank 23 fast on a tubular shaft 24 to which the door is attached. An abutment 25 may be provided on the radius rod to strike a roller 26 on the link 22 to initiate the movement of the door ; or two cams,may be provided, one to initiate the movement of the door, and the other to complete the movement. The radius rod is returned to the inward position by a tension spring 29 connected by a pair of cables 27, 28 to a plate on the shaft of the radius rod, this arrangement of cables and spring acting as a spring check when the radius rod reaches its inward position. Specification 416,884 is referred to for doors opened by the dropping bombs or independently.

Patent GB-810641-A (GB)
Title: Process for the manufacture of lubricating oil additives
Inventor: SHELLARD ARTHUR DONALD
IPC: C10G27/12
Filed: 1957-05-02
Abstract: An additive for lubricating oils is prepared by treating with an organic peracid (or with a mixture of an organic acid and hydrogen peroxide) a residual or distillate mineral oil fraction having an initial boiling point of at least 300 DEG  C., a viscosity-gravity constant of at least 0.90 and a sulphur content of at least 1 per cent by weight.  Suitable peracids are those of the fatty acids, such as performic, peracetic, perpropionic and perbutyric acids, those of the substituted fatty acids such as monochlor- or trichlor-peracetic acid, and those of the aromatic carboxylic acids such as perbenzoic acid.  The mineral oil fraction, before treatment, may be deasphalted.  It may also be diluted with a thinner oil or a solvent before treatment.  Thus it may be diluted with thin lubricating oil, gas oil, kerosene, xylene, toluene or petroleum ether.  In the case of solid organic acids such as trichloracetic acid, these may be dissolved in a solvent such as water or a low boiling alcohol before adding to the mineral oil fraction and hydrogen peroxide solution. After the treatment with the peracid, the mineral oil fraction may be freed of residual acid, hydrogen peroxide and water.  Thus, the treated oil fraction may be washed with water or an aqueous or alcoholic alkaline material, such as caustic soda, sodium carbonate or ammonia, and the last traces of water then removed by azeotropic distillation with a volatile solvent such as benzene, toluene or xylene.  Alternatively, after the treatment with the peracid, the aqueous phase may be removed, a solid alkaline material (e.g. sodium carbonate, lime or a mixture of sodium carbonate and activated earth) may be added and the mixture may then be filtered.  If desired, the mineral oil fraction may be treated with successive batches of peracid, with or without removal of the excess acidity and water after each treatment.  The lubricating oil additives thus prepared may be added to hydrocarbon lubricating oils, especially refined mineral oils, to increase their spreading pressure on solid surfaces. The lubricating oil compositions thus produced may be blended with fatty oils (e.g. rapeseed or lard oil) and/or synthetic lubricating oils (e.g. olefine polymers, alkylated aromatic hydrocarbons, dialkyl esters of dicarboxylic acids, trioctyl or tricresyl phosphate, tetraoctyl silicate, polymers or copolymers of polyalkylene glycols and esters and ethers thereof, and polyorganosiloxanes).  The lubricating oil compositions may also contain further additives such as oxidation and bearing corrosion inhibitors, detergents, dispersants, pour point depressants, viscosity index improvers, anti-foaming agents, rusting inhibitors, anti-wear agents, extreme pressure additives and dyes. In the examples, a diluted residual mineral oil fraction is treated with hydrogen peroxide and formic acid, water-washed and dried, and then added to mineral lubricating oil.

Title: Improvements in and relating to apparatus for operating coke oven doors and the like
IPC: C10B25/14
Filed: 1925-06-02
Abstract: 250,054. Wellman, Smith, Owen, Engineering Corporation, Ltd., (Wellman-Seaver-Morgan Co.). June 2, 1925. Coke ovens.-Apparatus for shifting coke oven &c. doors of the kind adapted to travel along the front of a battery comprises a support carrying upper and lower door-engaging hooks and means for moving the hooks into position so that the upper hook takes the weight of the door before the lower lower one which tilts the door outwardly at the bottom before it is removed from the opening. A ram 5 mounted on a transversely moving carriage 4 has secured to it a casing 7 supporting door engaging members 9 pivoted on a pin 11 and having arms 10 between which an upper door engaging hook 13 is pivoted on a pin 14 connecting the members 9. A lever 16 is mounted in the casing on a pin 17 and has a lower forked end 18, and supports on a pivot 22 a lower engagement hook 21 which is so connected by a rod 23 with the upper hook 13 that the latter engages the bracket before the lower hook. The arm 15 of the upper hook is connected by a link 30 to a lever 29. For operating the hooks a motor 24 by gearing 25, 26 and screw 27 causes a nut 28 to travel rearwardly whereby the lever 29 suspended therefrom and connected to links 30 and 34 causes the hooks 13 and 21 to move upwardly, the lever 29 first moving about a pivot 35 as fulcrum. When the ram 5 is moved forward the arms 10 and 18 serve to position the hooks 13 and 21 so that they may engage with the brackets 3. Further movement of the lever 29 causes the lever 13 to exert an upward thrust on the door and the lever 16 to exert an outward pull on the hook 21, the pivot 31 becoming the fulcrum of the lever 29 and the lower end of the door being withdrawn bv the hook 21. As soon as the lever 16 strikes an abutment 20 the pivot 35 becomes the fulcrum of the lever 29 which on continued movement lifts the door free of the opening so that the ram 5 can be backed away.
