Abstract: 118,677. Freeman, L. G. Sept. 6, 1917 Band apparatus.-Relates to machines for scouring or burnishing the heel breasts of boots and shoes, of the type in which an endless abrading-belt is led over guide-pulleys and over a removable working fixture of a form corresponding to the curve of the heel breast, such as described in Specification 14556/14. The working fixture 44 is provided with a stem clamped in an eye at the end of a lever 34 pivoted at 33 and pressed towards the belt by a spring 40. The lever may be locked by a set-screw in the position that it assumes under the action of the spring. When, as shown, the abrading-belt 46 is supported on a separate backing-belt 47, the backing-belt is run over a tension pulley 15 carried by a pivoted arm 13 controlled by a spring 18. The guidepulleys 25, 26 are carried by a member 19 adjustable in a slot 3 in the head 2 of the machine and connected by links 27, 28 to fixed points in the head, so that the pulleys may be shifted to adjust the direction in which the belt runs on to the working fixture, while maintaining the belt tension substantially constant. To take up unequal stretch in the belts and keep them in alinement, the spindle of one of the guide-pulleys is formed with an offset or bent portion and may be turned in its support. The head 2 is capable of angular adjustment on a bearing 6 on the frame of the machine. Dust &c. is removed by suction through passages 53, 57. The working fixture, shown in Figs. 3, 4 and 5 has its surface formed by cylindrical sleeves 60 running on pins secured in the base 56 of the device and a cap 62 formed with a stem 63, which is fixed in the base. The cap may be bevelled as shown at 65. The base is formed with an oil chamber 57 and supports a disk 66, upon which the edge of the belt runs. In a modification, the surface is formed by a single roller, and, as another modification, by a thin sheet of metal suitably curved.

Title: Process for the manufacture of wax-like oxidation products from solid low pressure polyolefines
IPC: C08F8/06
Filed: 1960-04-11
Abstract: A wax-like product is obtained by treating a powdery low pressure olefin polymer (e.g. polyethylene, polypropylene or polybutylene) at a temperature below its softening point with an oxidizing gas (e.g. oxygen or air-preferably ozonized) under conditions which permit intimate mixing.  Optionally the reaction is accelerated with an organic peroxide (of those listed, benzoyl peroxide is exemplified) or with acetic or formic acid.  The treatment may be in a fluidized bed, or in suspension (in the absence of methanol) in water or an organic medium such as an inert halogenated hydrocarbon or a liquid hydrocarbon which itself becomes oxidized under the conditions of the reaction.  The oxidizable hydrocarbons are preferably pre-oxidized and specified are gasoline, microcrystalline wax, Fischer-Tropsch paraffins, high pressure polyolefin waxes and thermally decomposed low pressure polyolefins.  The wax-like oxidation products are long-chain dicarboxylic acids also containing alcoholic and ketone groups; they may have an oxygen content of up to 40%, an acid number up to 400, a saponification number up to 500 and a molecular weight up to 5000. The wax-like oxidation products may be esterified with an alcohol or a phenol, optionally in the presence of a mono-, di-, or poly-carboxylic acid (e.g. montan wax acid), to give wax-like materials which find application alone or in conjunction with di- or poly-carboxylic acids, in shoe and floor polishes, polish emulsions, lubricants, and casting and impregnating waxes.
