Improvements in or relating to the purification of liquid hydrocarbons

Hydrocarbon oils are purified and freed from sulphur compounds by passing the vaporized oil together with hydrogen over a catalyst consisting of molybdenum or its compounds mixed with zinc and magnesium oxides, at a temperature of 200 to 450 DEG C. and under a pressure not exceeding 10 atmospheres. Crude benzol vapours are mixed with hydrogen preheated to 230 DEG C. and pass at atmospheric pressure through a reaction tube heated to 400 DEG C. and containing a mixture of molybdenum, zinc and magnesium oxides. Molybdenum oxide may be replaced by ammonium molybdate. The process effects decomposition of the sulphur compounds with the formation of sulphuretted hydrogen, without destructively hydrogenating the oil. Specification 345,738 is referred to.

The tip of the locking arm moves in a slideway fastened to the strut while its two ends are pivoted to the ladder uprights, allowing it to be moved between deployed and folded positions.

Folding tray for foldable step stool

The present disclosure relates to a step stool, and particularly to a folding step stool including legs that fold between an opened, use position and a collapsed, folded position. The present disclosure also relates to a tray assembly that moves relative to the legs and is used for storing or holding articles associated with use of the step stool. The step stool includes a mechanism to coordinate the movement of the tray assembly and a step of the step stool when the step stool is moved between the opened and collapsed positions.

Stabilizing base for platform and stockroom ladder used to e.g. trim hedges, has support zone fixed to posts of ladder, and openings formed in support zone by folding two tabs, where feet of ladder exceed support zone by ten mm

The base (100) has a support zone fixed to posts (181) of a ladder. Feet (180) of the ladder exceed the support zone by 10mm. A stabilizing base portion i.e. rectangular sectioned tube, is constituted of a folded sheet. Two sides of the sheet form the support zone and a reinforcement rib, respectively. Two openings are formed in the support zone by folding two tabs. The feet traverse the base portion through the openings. The base portion is fixed to the posts by screws (170) and nuts.

Stepladder with latch stud and method

A stepladder includes a front section having a first front leg and a second front leg. The stepladder includes a step attached to the first front leg and the second front leg. The stepladder includes a latch engaged with the step. The stepladder includes a rear section having a first rear leg and a second rear leg and a cross bar attached to the first rear leg and the second rear leg. The rear section is pivotably attached to the front section. The rear section has a first stud which extends from the first rear leg toward the second rear leg and separate and apart and not in contact with the second rear leg and not in contact with the cross bar. The latch is engaged with and latched to the first stud to define an engaged position where the first front leg and the first rear leg are in an open position and form an inverted v shape and are prevented from folding together, and the latch when pulled up from the engaged position, disengages from the first stud and allows the front section and rear section to fold together into a closed position where the first rear leg and the first front leg are in parallel. A method of positioning a step ladder.

Improvements relating to stepladders

923,792. Step ladders. B. LAMBERTI. Feb. 5, 1960 [Oct. 21, 1959], No. 4189/60. Class 20 (2). A step-ladder adapted to fold laterally in the plane of the ladder comprises rungs 1 in two halves pivoted to the stiles 6, 7 and a central rod 3 and side members 8, 9 of the back rest connected by two similarly arranged rungs 30 and crossed links 11 to a central rod 10 and a platform 24 formed of a lazy tongs. To allow the ladder to fold, one end of each of the crossed links 11 slides in a slot and the lazy tongs 24 engage the top rung 1 by detachable pins and are connected to the top rung 30 by springs 23. When the back rest has been folded against the ladder 6, 7, a lever 21, Fig. 8, is operated which by means of a fork engages a projection 22 on a link 18 which raises the rod 3 and causes the ladder to fold laterally, a projection 28 on the bottom of the rod 3 simultaneously engaging a projection 29 on the rod 10 which is thus raised and causes the back rest to fold laterally. The ladder is spread laterally by levers 27 on the ends of the top rung.
