Abstract: Aralkylmonohydroperoxides having the general formula <FORM:1006319/C2/1> wherein Ar is an aryl or aralkyl radical and R and R1 may each be either a hydrocarbon radical or a hydrogen atom, are made by oxidizing a hydrocarbon having the general formula <FORM:1006319/C2/2> with oxygen or oxygen-containing gas without any irradiation of the said hydrocarbon, in the absence of catalysts and in the substantial absence of water and pH-controlling additives, while the pH (determined by extracting a given amount of the reaction mixture with an equal volume of water and finding the pH of the aqueous extract) lies between 2.8 and 6, preferably 4.5 and 5.5, and the reaction is performed at an elevated temperature below the lowest possible explosive decomposition temperature of the oxidation products formed, to achieve conversion of said hydrocarbon while keeping the formation of by-products to a minimum.  The residence times should be as short as possible and should preferably not exceed 120 minutes.  The reaction temperature normally lies between 90 DEG and 135 DEG  C.  An example describes the oxidation of cumene to cumene hydroperoxide.

Abstract: 1,272,097. Hydraulic braking systems; valves. CLAYTON DEWANDRE CO. Ltd. 12 Feb., 1970 [28 March, 1969], No. 16307/69. Headings F2F and F2V. In an hydraulic system for supplying pressure fluid to brake actuators 7 and also to auxiliary devices (not shown) the working fluid is continuously circulated from a reservoir 1 by means of a pump 2 through a closed braking circuit having accumulators 5 and drivers valve 6, a solenoid valve 10 being disposed in the system through which fluid passes to the auxiliary devices but which is actuated by switches 11, 12 in parallel and responsive to the pump 2 output pressure and the reservoir 1 level respectively to cut-off the supply to the devices but not to the brakes when the output pressure or reservoir level fall below a predetermined value. Valve 10 has a rod 26 actuated by the solenoid when either switch 11 or 12 is operated to depress a valve member 21 having a reduced portion sliding in a bore of a member 20, fluid then passing from an inlet 14 into the hollow interior of a piston 17 by way of bore 28, the bore in member 20 and radial passages (not shown) communicating with grooves 24 in member 20. Fluid pressure is thus equalized at opposite faces of piston 17 which is thus moved under the action of a spring to engage a seat in a recess 29a by means of a piston extension 17a thereby cutting off the fluid supply to the auxiliary device from inlet 14 by way of outlet 15. On de-energizing the solenoid, spring 27 retracts member 21 and closes inlet 14 from the piston 17 hollow interior, fluid trapped in this interior passing to the reservoir by way of a spill passage 23.

Abstract: 221,037. Knecht, E. June 25, 1923. No Patent granted (Sealing fce not paid). Latches, sliding; fastenings operated mechanically from a distance. - In means for operating fanlight windows there is provided a spring-actuated bolt 20, Figs. 1 and 8, arranged centrally on the fanlight together with an independently movable bolt retractor which is extended for connection to the operating-mechanism arranged on the frame at the side of the window. The retractor engages automatically with a catch 23 when the fanlight is closed and is adapted to be retracted by the operating-mechanism when the latter is moved to open the window. The latch bolt 20 which is slidably held in a casing 19 on the fanlight is controlled by a spring 22, as shown in Fig. 6, and it snaps into engagement with a catch 23 when the window is closed. The bolt retractor is composed of a shaft. 15 mounted in bearings 16 on the fanlight and is provided with a crank at each end. The crank 17 projects through a segmental slot 18 into the casing 19 and into an elongated slot 21 in the bolt 20. The other crank is rigidly connected to a rod 10 linked by means of an eye 9 to an eye 8 formed on a lever arm 7. The arm 7 is bent from the upper end of a vertical shaft 1 which is mounted in bearings 2 on the window frame 3. An operating-lever 5 is formed at the lower end of the shaft 1, a grooved spring element 6 being provided to retain the lever in certain positions. A modification of the connection of the shaft 15 and rod 10 is shown in Fig. 7, in which an eye 28 formed on the rod 10 is loosely held between nuts 26 and 27 on a crank 25 on the shaft 15. In the arrangement shown in Fig. 8, the bolt retractor is formed of two bell crank levers 30, 32 connected by a rod 31. The lever 32 is connected to operating-mechanism which consists of a rod divided into two parts 33, 35 connected by a slidable hine joint the lower part being fitted at its free end with a handle 38. In Fig. 13 a cord is connected in the middle of a crank 43 of the shaft. 15, one part 44 of the cord being ]ed over an offset deflecting pulley 45 and then behind a pulley 46 and another part 49 of the cord passes over a pulley 50. A pull on the part 44 turns the shaft. 15, retracts the bolt and then, owing to the advanced position of the pulley 45. opens the fanlight. In the modification shown in Fig 17 the cord is first coiled round the crank 52 of the shaft 15 being clamped thereon. One part 53 of the cord passes between pulleys 59 arranged on a staple 62, the latter being connected to one end 61 of a blade spring 60, the opposite end of which is secured to the wall. When the cord 53 is pulled the spring bends and allows the cord to act in an outward direction to retract the bolt and then open the fanlight.
