Tip-wagons.-In a tip-wagon of the type which tips automatically when loaded and is restored automatically to the normal position when empty, a guide 4 on the bottom 3 of the wagon engages a curved guide 2 on the underframe 1 or vice versa so that the centre of gravity S<1> of the loaded wagon in the normal position lies on one side of the point of support, while the centre of gravity of the unloaded wagon in the tilted position lies on the opposite side of the point of support. One side wall 7 is pivoted to the bottom 3 and itsupper edge 8 is guided either in vertical guides 9, or as shown in Fig. 4, by means of rods 13 which keep the wall 7 substantially at right angles to the bottom. The other side wall 14 is either fixed or connected by rods 15 to the cranked rods 13 so as to open as the wagon tilts. The rolling movement of the guide 4 on the curved guide 2 may be constrained by providing interengaging teeth on the guides or by connecting them by a pivoted link. A locking-pawl 5 is provided to engage the guide 4 so as to retain the wagon in its normal position, and automatically locks the wagon in its return from the tilted position. The pawl is mounted on an eccentric 17, Fig. 5, keyed to a spindle 6, which is rotated to release the guide 4. A counterweighted catch 10 is also provided to retain the wagon in the tilted position, and the two catches may be connected by a rod so that release of the catch 10 ensures the pawl 5 being in the " set-for-locking " position indicated in Fig. 5.

Title: Hydrogenation of organic materials
IPC: C07C13/16
Filed: 1937-06-29
Abstract: In the hydrogenation of benzene, a preliminary purification for the removal of catalyst poisons is effected by treating the benzene with sulphuric acid (to remove thiophene), and subjecting it to fractional distillation until the distillate passing over becomes free from carbon disulphide.  In an example, benzene is agitated with concentrated sulphuric acid, the acid layer is withdrawn, and the benzene is washed several times with water and then with a solution of sodium bicarbonate, carbonate or hydroxide, fractionally distilled until the distillate passing over no longer yields a precipitate with cyclohexylamine (test for carbon disulphide), and then hydrogenated at 180 DEG  C. under 34-120 atmospheres pressure of hydrogen in the presence of a nickel catalyst prepared by the process described in U.S.A. Specification 1,628,190.  Comparative examples show the effect of removing thiophene only by the sulphuric acid treatment, and of removing carbon disulphide only by the fractional distillation. If desired, the fractional distillation may precede the sulphuric acid treatment.  Specifications 258,576 and 315,439, [both in Class 91], are referred to.

Title: Improvements in or relating to devices for testing the security of roof bolts and the like
IPC: G01N3/00
Filed: 1953-07-03
Abstract: 726,279. Testing the security of roof bolts. GULLICK, Ltd., and SEAMAN, T. July 3, 1963, No. 18440/53. Class 106(2). A device for testing the security of roof bolts, as used for example in coal mines, comprises an abutment member adapted to be secured to the lower end or head of a roof bolt protruding from the roof, an extensible device between the roof and the abutment member to urge the latter away from the roof and a tell-tale device for indicating any movement of the abutment member away from the roof under the action of the extensible device. In Fig. I the abutmeiit member 15 is screwed onto the protruding end 13 of a roof bolt 12. A hydraulicallyactuated extensible member 18 is placed between a flange 14 on the member 15 and a roof plate 11. A washer 21 is held firmly between the upper part of the member 15 and the roof plate 11. In use, pressure fluid is pumped into the extensible member 18 and at a certain pressure the load on the roof bolt 12 will be'such that the washer 21 has become slack. Access for testing the tightness of the washer and noting immediately it becomes slack is provided by an opening 18a in the sleeve 18. If, when the washer becomes slack, the load as indicated by a pressure gauge is below a predetermined level, then this is an indication that the roof bolt has not been properly anchored in the roof. The modification shown in Fig. 4 is applicable to cases where instead of the screw-threaded end of the bolt protruding from the roof only the head of the bolt is accessible. For this, the apparatus described with reference to Fig. 1 is used together with (a) an adaptor extension 22 screwed into the member 15 and having a clawed end 23 for gripping the bolt head, and (b) an extension piece 25 for disposal between the extensible member 18 and the roof. The mode of operation is identical with that already described.
