Title: Improvements in or relating to weighing scales
IPC: G01G19/413
Filed: 1925-08-05
Abstract: 260,678. White, A. E., (Dayton Scale Co.). Aug. 5, 1925. Multiple - indication apparatus. - A weighing- scale is provided with a variable ratio device controlled by the operator comprising a plurality of levers of different multiplying ratios, certain or all of which levers are adapted to be rendered active or inactive by manual selection so that a plurality of ratios greater than the number of levers employed may be obtained. The invention is of general application, but is preferably applied to a machine in which the beam is not subject to variable displacements under varying loads, e.g. the machines described in Specifications 182,665 and 260,679, [both in Class 143, Weighing-apparatus]. As shown diagrammatically in Fig. 9, the weigh-pan 28 of a weighing- scale is connected to the weighbeam 21 through one or more of a system of levers corresponding to different leverage ratios. Levers 35, 37, 39, 41 correspond to multiplying ratios of 1, 2, 2, 4, and levers 35<a>, 37<a>, 39<a>, 41a to ratios of 10, 20, 20, 40 respectively. Each lever is pivoted at the outer end to the frame, and is provided near the inner end with a knife-edge 43 adapted to bear, when the lever is in active position, upon one of a series of bearing plates 52 which are mounted in stirrups 51, Fig. 5, pivoted to a frame 50 depending from the beam. A pivoted plate 53 is disposed adjacent the inner end of each lever and is adapted upon the energization of a cooperating electro-magnet 59, Fig. 10, to tilt and thereby lift the lever out of action. The deadweight of the lever is compensated for by a lever 35<c> which is pivoted to the frame and normally bears upon the plate 53, but which, upon the tilting of the plate is deposited upon the bearing plate 52. The electro-magnets are operated by two series of keys 63, 64 corresponding to the tens and units respectively. Each key is provjded on its underside with projections 65 adapted to engage levers 66, which when depressed close contacts 67 in the circuits of the magnets, thereby leaving in acting position only that weighing-lever or combination of levers which corresponds to the desired ratio. In operation, the keys corresponding to the price per unit weights of the goods being weighed are depressed, and the value of the goods is automatically indicated on the weights chart or is printed by printing means connected thereto. The invention may also be applied to article-counting weighing scales.

Title: Improvements in and relating to the distillation of resins and to the employment of products obtained therefrom
IPC: C09F1/00
Filed: 1936-07-16
Abstract: Naturally occurring resins such as copals or dammars are subjected to distillation in the presence of a basic material, such as lime, calcium, potassium or sodium carbonate or hydroxide, to obtain liquid distillates of commercial value.  The distilling temperature varies from 300 to 700 DEG  C.  Atmospheric or greater pressures may be used.  The proportions specified comprise 1 to 200 parts of the basic material to 100 parts of resin.  The more volatile products may be recovered by absorption with active carbon, silica gel or suitable liquids.  The distillates obtained may be re-distilled or otherwise refined to obtain fractions suitable as lubricating oil, fuel oil or petrol substitutes or as chemical intermediates for the manufacture of alcohols, halogenhydrins, alkylolamines &c.  A particular application of the oils obtained is as collectors in flotation processes for sulphide minerals or minerals containing native copper, silver or gold.  A suitable oil is obtained by varying the proportion of basic material, temperature and pressure of the distillation to obtain an oil having a minimum iodine number of 175.ALSO:Oils for use as collectors in flotation processes for sulphide minerals or minerals containing native copper, silver or gold are obtained by subjecting naturally occurring resins such as copals or dammars to distillation in the presence of a basic material, such as lime, calcium, potassium or sodium carbonate or hydroxide. The distilling temperature varies from 300 to 700 DEG  C., and the mixture may be completely carbonized.  Atmospheric or greater pressures may be used.

IPC: B66C23/10
Filed: 1925-08-07
Abstract: 256,781. Weddell, A. H. Aug. 7, 1925. Jib cranes.-To obtain horizontal travel of the load while luffing, the jib foot B, see Fig. 1 accompanying the Provisional Specification, is constrained to move vertically through a distance proportional to sin a, and the hoisting rope passes over a fixed pulley C at a suitably chosen height above the lowest position D of the jib foot. In a modification, which is geometrically equivalent, the jib foot is pivoted at F, see Fig. 1 (Comp.), and the pulley C moves horizontally. Referring to Fig. 1 (Prov.), the jib foot B is constrained to move vertically and the necessary additional constraint is obtained by a radius rod pivoted at D and connected to an extension of the jib at E so that BE=DE. The method of calculating the lengths DE and DO for a given length of jib and a given rope purchase between C and A is set out in the Specification. In a modification, the jib is extended to F so that EF=EB, and the point F is constrained to move horizontally. In Fig. 1 (Comp.) the point F is fixed, and the point C is constrained to move approximately horizontally so as to remain vertically above the point B, the relative motions of the points F, B, and C being thus the same as before. The constraint is provided by carrying C on a mast pivoted at F and connected with the jib by links M, N and a bell-crank lever K, L, or by ropes passing over fixed pulleys. The jib may be balanced by a weight on an extension below F, or on the lever K, or suspended from ropes led between C and A, or between B and a pulley above B.

Abstract: 1456668 Expansion joints; methods of laying pipe-lines E RASMUSSEN AS 23 April 1974 [26 April 1973] 19907/73 Headings F2G and F2P An expansion pipe joint comprises an expansible member such as a bellows 10 fixed by circumferential welding to a short tube 12 at one end and a longer tube 14 at the other, both of which can in turn be welded to the pipes to be joined. Adjacent their joints with the bellows, tubes 12 and 14 each have welded thereto an exterior annular flange 18, 20 which incorporates cylindrical edge portions 22 and 24 projecting towards each other. When hot liquids are passed through the pipes, axial expansion of the pipes causes the bellows to contract and eventually, on increasing the temperature of the liquid, the axially facing parts of edge portions 22 and 24 abut whereupon they can be joined together by welding at this abutment. The joint can be thermally insulated by enclosing it in an exterior protective tube casing, a hole in which allows introduction of foam insulating material and is sealed thereafter by a stopper.
