Title: Improvements in tipping vehicles
IPC: B60P1/16
Filed: 1934-02-12
Abstract: 438,500. Tipping vehicles. CAMBESSEDES, J. E. F., 18, Boulevard Arago, Paris. Feb. 12, 1934, No. 4636. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 14, 1934]. [Class 108 (i)] In vehicles of the kind in which the body is adapted to be tipped by means of jacks carried by the vehicle the jacks are so mounted that they may be turned from their vertical working position into more or less horizontal transport position suitable means being provided for connecting the plunger heads of the jacks to the tipping body when desired. The hydraulic jacks 2, Figs. 1 and 2, are mounted on a cross member 24, which is mounted on trunnions 25 in the chassis 19, so that the jacks may be moved either into inoperative position, that is inclined or substantially horizontal or into operative vertical position. This rocking movement is performed by means of a lever 27 and rod 28 from the driver's cabin. When in vertical position a hook 29 on the plunger engages a cross-bar 30 on the body 1 the hook being automatically locked to the bar 30 when tipping takes place by means of a pawl 32 pivoted on the plunger and caused by means of a spring 33 to close the open face of the hook 29, the pawl being displaced to free the hook 29 when the body 1 is returned. Fig. 5 shows a rack jack 2 which is rocked by the rod 28 and is provided with a roller 48 adapted to engage a recessed mount 49 on the body subsidiary frame 37. A pawl 38 pivoted on the subsidiary frame 37 is adapted to confine the roller 48 by means of an offset 40, a pin 42 on the chassis engaging a slot in the tail of the pawl to disengage the pawl from the roller 48 when the body returns to travelling position and allowing the jack to be rocked to inoperative position. Fig. 7 shows a modification in which the jack plunger head 34 is permanently secured to the crossbar 30 on the body subsidiary frame 37. The cross-bar 90 is carried by cranks 91 trunnioned at 92 in a hangar 37 trunnioned on the frame 37 and the lower end of the jack is trunnioned at 25 to the chassis 19. Relative movement between the hangar 37 crank 91 and jack 2, permits the latter to assume its inoperative position when the body is lowered. In another form in which a rack jack is used the usual transmission gear between the crank handle and the rack may form part of the jack and work with it. As shown in Fig. 1, movement of the lever 27 to mid position 27<a> declutches the pump and stops tipping while further movement of the lever to position 27b opens a valve through rod 28 and spring 28<b> to allow the pressure fluid to return to the reservoir to return the body to travelling position. A catch 53 may be provided whereby say the engine clutch cannot be operated until the jacks are in inoperative or travelling position.

Filed: 1929-02-12
Abstract: 328,704. Soc. Anon. Fonderia del Pignone. Nov. 13, 1928, [Convenion date]. Parachutes.-A body to be dropped from aircraft is provided with a parachute which opens at a height above the ground determined by the length of a cable attached to a, pilot weight that is paid out during the descent, the disconnection between the pilot weight and the body being subject to an initial retardation sufficient to enable the body to, assume a stable position. The body is shown suspended from an aircraft, during which time a pilot weight d of greater penetration and specific weight than the body, is retained by a pin e connected to the aircraft. When the body falls the pin e is withdrawn, and as the body assumes an upright position the weight d detaches itself, after overcoming the resistance of a dashpot i, and unwinds a cable k from a drum l. The cable k passes over a pulley m on a thimble n which normally keeps two balls p in engagement with a spindle r, the thimble being urged by a spring to release the balls p when the tension in the cable k becomes slackened upon contact of the pilot weight with the ground or water. When the balls p are released a spring s acting on the spindle r ejects the parachute. To prevent premature discharge of the parachute, a pin u engages a hole in a tail piece t on the thimble n, this pin being screwed so that it is withdrawn bv rotation of the drum l as the cable is paid out.

Title: Improvements in or relating to the method of dewaxing a wax-bearing oil, to a lubricating oil of low pour point, and method of preparing same
IPC: C10G73/04
Filed: 1935-02-15
Abstract: Polymerized cyclic hydrocarbons, for use as dewaxing agents for petroleum oils, are made by heating naphthalene anthracene, fluorene, phenanthrene, benzene or homologues thereof with aluminium chloride or similar Friedel-Crafts reagent preferably p  between 90 to 150 DEG C.  Naphthalene is dissolved in kerosene and heated above 90 C. for 6 hours with an equal amount of aluminium chloride.  The resulting product is distilled under reduced pressure to remove tetra methyl naphthalene, b -b -dinaphthyl and tetramethyl picene (crackene or naphanthracene derivative), leaving a tarry residue which may be dissolved in benzene and petroleum naphtha added to yield a precipitate of tetranaphythyl (C40H26).  Aluminium chloride may be replaced by the halides of zinc, antimony, iron, cadmium, boron, manganese, nickel or tin.ALSO:Mineral oils are dewaxed by adding a condensation product of an aromatic hydrocarbon formed by heating with a Friedel-Crafts catalyst, chilling and separating the precipitated wax. Naphthalene, anthracene, fluorene, phenanthrene, benzene or homologues thereof are heated with aluminium chloride at 90--150 DEG  C., and the condensed product is distilled to remove the lighter fractions up to 300 DEG  C., which consist of tetra-methyl-naphthalene, b -b -di-naphthyl and tetramethyl picene, leaving a tarry residue which is used as the dewaxing agent.  This tar may be dissolved in benzene and petroleum ether added, whereupon a precipitate of tetra naphthyl is formed, which after drying may be used as the dewaxing agent.  Aluminium chloride may be replaced by the halides of zinc, antimony, iron, cadmium, boron, tin, manganese or nickel.  The oil is diluted with solvents such as benzene, acetone, dichlorethylene, naphtha, methyl ethyl ketone, aliphatic alcohols or mixtures thereof, and a small amount of the tarry residue is added.  The resulting solution is chilled and the wax separated in a centrifuge or filter.  Filter acids as diatomaceous earth may be added before the chilling stage.  Condensation products formed at a high temperature are particularly effective for heavy residual oils.
