Title: Machine for wrapping and labelling cylindrical or prismatic articles
IPC: B65C9/34
Filed: 1929-06-17
Abstract: 334,636. Hartman, R. June 17, 1929. Packeting by wrapping-up.-In a machine for wrapping or labelling cylindrical or prismatic articles, such as chocolate sticks, sugar cigarettes, rolls of tablets, bottles, and the like, the article 1 and wrapper or label 3 are deposited upon a leather, webbing, rubber, or like band 2 secured at one end to a cam-controlled lever 5 and resiliently held at the other by a spring 13. A ram 4 presses the article, together with the band and wrapper, downwards between rollers 10, 11 mounted on a horizontally oscillatable carriage 8. During the descent, a lever 6 carrying the roller is moved into the position shown in Fig. 2, so that a partial enfolding takes place, the lever 5 moving to the left and then backwards to stretch the band. The carriage 8 and associated rollers are then moved to the left to complete the application of the wrapper. The higher position of the roller 10 ensures that the left hand end of the wrapper is rolled under the other end. Upon arrival beneath a plate 12, the parts 6, 10, 11 take up, their original relative positions and the wrapped article is pressed up into the path of an ejecting member 14.

Abstract: 936,486. Electrical plugs. K. Z. RUMBLE. May 26, 1960 [May 29, 1959 (3); June 10, 1959], No. 18680/60. Class 38 (1). A plug consists of a body 10 with an earth pin 30 and pairs of retractable contact pins 24, 26 spaced further apart the further they are from the earth pin, to provide, with the earth pin which is common to all of the pairs of contact pins, at least two triangulated sets of pins, each set being capable of engaging one of a standard range of three-member outlets. The pins can be flat or rounded, and the earth pin when of the rounded type is telescopic, composed of units of different diameters, but when of the flat type is of jack-knife construction (see Figs. 7 and 8, not shown). Each contact pin is housed in a metal socket 32 in a hole 34 retained in position by a cover-plate 36. Threads 38 in the socket engage with threads 40 on the distal end of the pin. A head 42 on the pin prevents complete withdrawal from the socket. Rotation of the pin either locks it in projected position or frees it for retraction into the socket 32. The plug body and coverplate are made of resilient material for use as a two-pin plug when the earth pin will be retracted, and the plug can be squeezed to give the correct pin spacing. Fig. 10 illustrates a plug having both rounded pins and flat pins 104, 106, 108. The pins may have rubber noses to avoid short-circuiting.

Polybutadienesulphone filaments are produced by spinning a solution of a butadiene polymer in which at least 85% of the repeating units are butadiene units connected in the 1,4- position, and a hydroperoxide catalyst, into a reaction medium containing sulphur dioxide to form a filament having a combined sulphur content (as sulphone) of at least 27 to 32 grams per gram equivalent of polybutadiene, using a spin-draw ratio of less than 1, preferably not more than 0.8, removing the filament so formed from the reaction medium and immersing the filament in an aqueous alkaline bath. The units connected otherwise than in the 1,4-position may be of the 1,2-vinyl type having the structure  Reaction conditions are preferably controlled to provide a final polymer having a combined sulphur content of 28 to 32 grams of sulphur, as sulphone, per gram equivalent weight of polymerized butadiene. The butadiene polymers may be dissolved in aromatic, aliphatic, or cycloaliphatic hydrocarbons such as benzene, hexane or cyclohexane, in halogenated hydrocarbons such as dichlorodifluoromethane or in cyclic ethers, particularly tetrahydrofuran. The catalyst may be a hydroperoxide in which the hydroxy group is in the alpha position with respect to the peroxide group. Tertiary butyl hydroperoxide is one preferred catalyst. The sulphur dioxide is preferably dissolved in a coagulating bath. The bath preferably contains a poor solvent for the butadiene polymer, or a mixture of one or more solvents for the polymer with one or more non-solvents. The bath may contain, in addition to the sulphur dioxide, 100% ethyl alcohol or a mixture of up to 90% of benzene with 10% of a lower alkyl alcohol containing from 1 to 4 carbon atoms. Cyclic ethers, in particular tetrahydrofuran, are preferably used in the coagulating bath, together with sulphur dioxide. In these baths, up to 30% of water may also be present, but the water content of the bath is preferably kept below 10%. The alkali in the aqueous alkaline bath may be sodium, bicarbonate, sodium carbonate, trisodium phosphate, sodium hydroxide or a quaternary amine such as tetramethyl ammonium hydroxide. 1 to 10% aqueous solutions of sodium bicarbonate at, 80 to 100 C. are preferred. The filaments may be treated in the alkaline bath in either the drawn; or the undrawn state. Drawing, e.g. at a stretch ratio of 1.5 to 3À5 may. be performed in an aqueous bath at room temperature up to about 100 C. The as-spun filaments may be treated first with an oxidizing agent, such as a 0À2 to 0.5% aqueous solution of potassium permanganate, and then passed through a bath containing a reducing agent, such as sulphur dioxide, before being passed through the alkaline bath. The spindraw ratio may be calculated from the expressions:-
