Title: Loading pallets
Inventor: LUCHFORD LAURENCE RICHARD
IPC: B65D19/00
Filed: 1962-05-15
Abstract: 1,038,767. Load-handling platforms. TRIANCO Ltd. May 13, 1963 [May 15, 1962], No. 18640/62. Heading B8H. A platform for loading freight, e.g. into aircraft, has buttons 16 secured to its vertical edges for receiving loops of a load-retaining net and a peripheral rib 12 which serves as a support for net-loop-retaining resilient members 21. The rib also serves as a rubbing strip when the platform is slid between the customary guides in an aircraft and for this purpose may be fitted with a synthetic plastic antifriction inset 14. The platform consists of a cellular arrangement of struts (not shown) with horizontal plane sheets, secured to the struts, forming the top and bottom surfaces of the platform. The whole is enclosed in a surrounding frame of inwardly facing channel members 3 with which the rib 12 is integral. The upper flanges 6 of these channels may be apertured at intervals to receive lashing eyes or shackles and the channel webs may also have sockets for retaining spigots fitted in an aircraft. Four of the sockets may be used to receive the lifting pins of a sling and spreader beam, though to prevent a socket required to be used only to receive a retaining spigot from being used as a lifting point, such socket may be blocked off by a screw 37, Fig. 5 (not shown) in the flange 6 which renders it effectively deep enough only for the spigots and not for the lifting pins.

Abstract: 1,142,543. Extractive distillation. HEINRICH KOPPERS, G.m.b.H. 24 April, 1967 [13 Oct., 1966], No. 18700/67. Heading C5E. Aromatic hydrocarbons are separated from non-aromatic hydrocarbons by an extractive distillation process characterized by the following features :- (a) the extraction agent, e.g. propylene carbonate, contains as additives compounds similar to, but not the same as, those being extracted (e.g. if only benzene is to be extracted, then the additive may be xylene or Cg aromatics); (b) at least two extractivedistillation columns, shown as 14 and 19 in the Figure, are installed one behind the other in series, the downstream column 19 being operated at a lower pressure than the upstream column 14; and (c) the extract is treated in a number of column systems in series, each system corresponding to a desired product (e.g. column systems 23 and 29 for production of benzene and toluene respectively), each system consisting of an extractive stripper section (e.g. 23a), an extractive rectifying section (23b), a distillative rectifying section (23c) and a distillative stripping section (23d), the two extractive sections and the two distillative sections each constituting a pair of sections between which vapour and liquid interchange may take place, and the head of the extractive rectifying section (23b) being connected to the head of the distillate stripper section (23d), the bottom product of the preceding column system being fed between the a and b sections and the extraction agent being fed to the b section, while at the same time a pure aromatic extraction product is removed overhead from the c section, while a non-aromatic fraction is obtained as bottoms product in the d section. Sections a, b, c and d may be arranged differently from as shown in Fig. 3, e.g. a and b in one column and c and d in another. In a modification, the b section may be omitted if the next higher boiling product is not required in quantitative yield, e.g. as shown in column system 36, and it is also possible for the d section to be omitted in any system in which the heads product is not required in a pure state. The additive to the extraction agent may be already present therein, or may be added thereto, and part of the additive may be added directly to columns 14 and 19 at 41 and 42 above the feed-point of the extraction agent. In the Figure, benzene, toluene and xylene are recovered at 24, 31 and 37 respectively, and non-aromatics at 16, 21, 27, 34 and 39 all of which are combined in manifold 17.

Inking - apparatus. - In stencil-duplicating machines of the type in which a viscous or pasty ink is employed and is distributed over the surfaces of impermeable inking-cylinders with the aid of inkdistributing rollers, means is provided which are associated with the frame of the machine, and are adapted to be actuated to bring the rollers into the working position after they have been inserted through an opening in the side frame of the machine. Axial motion may be imparted to one or more of the rollers while another or others are precluded from such motion. As shown, the machine comprises inking-cylinders 2, 2<a> over which travels an endless flexible stencilcarrier 3, the ink being distributed by means of rollers 11, 11<a>. A pair of levers 5, 5<a> is pivoted on the shaft 4 of the cylinder 2 at each side of the machine, and the levers of each pair are connected by a common pin 8 engaging slots 7, 7a therein, each pin 8 being carried. by a lever 9 adapted to be depressed about a pivot 10 to separate the levers 5, 5<a> and so to permit the rollers 11, 11<a> to be inserted. A spring 6 connected to the levers 5, 5a of each pair returns them to normal position, and curved parts of the levers engage the spindles 14, 17 of the rollers 11, 11<a> to move the rollers into their working positions. In a modification, not shown, the spindles are engaged by slidably guided members in place of levers. Each of the rollers 11, 11<a> has a knob 13 or 13<a> to facilitate manipulation. The roller 11 is prevented from moving axially and its entry into correct position is facilitated bv means of conical surfaces 15 on the spindle 14 separated by a groove in which the levers 5 engage. The roller 11<a> is reciprocated axially by a lever 23 oscillated about an axis 24 and provided with a boss 22 engaging a groove in the spindle 17. This groove is formed between the bases of two conical parts 19, 20, and the boss 22 has a conical surface also, which, as soon as the lever 23 starts oscillating, and if the roller had not previously been inserted correctly into position, engages one of the parts 19, 20 and lifts the end of the roller so that the boss engages between these two parts. The.axial movement of the roller 11<a> is limited by the engagement of reduced parts 18 of the shaft 17 with the levers 5<a>.
