Title: Improvements in machines for making glass bottles
IPC: C03B9/40
Filed: 1933-05-15
Abstract: 406,164. Glass manufacture. BARTOS, F., Holobkov, Rokycany, Czecho-Slovakia. May 15, 1933, No. 14074. Convention date, May 15, 1932. [Class 56.] Relates to bottle-making machines in which the successive operations are controlled by rotating cams, as in the machine described in Specification 259,601, [Class 56, Glass], and consists in providing mechanism for automatically starting and stopping the rotation of the cams and for enabling the duration of the different operations to be regulated separately. The apparatus comprises a rotating disc a which is secured to the cams that control the operation of the machine and has on its edge three notches b<1>, b<2>, b<3>. A bellerank lever y has on one arm a roller c which enters the notches, and this arm is also pivoted to a rod d connected to a clutch. A spring y<2> keeps the roller c pressed against the edge of the disc a, and the clutch is disengaged and stops the rotation of the disc a when the roller enters one of the notches. Three cams e are secured to the face of the disc, each cam having two noses e<1>, e<11>. These cams rock a spring-pressed lever f which turns a ratchet wheel j on a shaft k by means of a pawl i. The shaft has three recesses k<1> into which a roller l on a bellcrank lever m enters. A vertical rack s is raised by two pawls q, r, which are reciprocated by eccentrics u on a continuously rotated shaft, v. The upper end, s<1>, of the rack engages a crosshead y<1> on the bellcrank lever y. In operation, the rise of the lever s turns the lever y until the roller c is withdrawn from the notch b<1> and the rod d closes the clutch. The disc a then rotates, and the nose e<1> of the cam e rocks the lever f and turns the shaft k. Rotation of the shaft rocks the lever m, and a roller o on its lower arm withdraws the pawls q, r from the rack s and allow the rack to drop until its head strikes a bracket w. Shortly before the roller c enters the next notch b<2>, the nose e<11> of the next cam e rocks the lever f and turns the shaft k until the roller l enters a recess k<1>. When this occurs, the pawls q, r engage the rack s which rises until it again rocks the lever y and starts the rotation of the disc a. The duration of the period during which the disc a is at rest depends on the time required for lifting the rack s, and this period can be adjusted by raising or lowering the bracket w by means of a screw spindle x. Specifications 154,915 and 264,062, [both in Class 56, Glass], are referred to. The Specification as open to inspection under Sect. 91 states that the racks s may be replaced by other uniformly-moving rigid bodies or by oil pumps. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the production of cellulose esters
IPC: C08B3/00
Filed: 1940-09-17
Abstract: Cellulose is esterified with an organic acid anhydride in a medium which is a solvent for the primary ester formed, and which comprises a neutral liquid chlorinated lower aliphatic compound containing at least two chlorine atoms each of which is attached to a carbon atom adjacent to a carbon atom having no attached chlorine atoms.  The neutral organic liquid may be ethylidene chloride, or 1.3-dichloropropane.  This liquid may be employed in admixture with acetic acid or other organic acid.  The process may be employed in the production of cellulose esters of aliphatic acids containing up to four carbon atoms, e.g. cellulose acetate, propionate, or butyrate.  Cotton linters or wood pulp may be pretreated with formic or acetic acid containing a small amount of sulphuric acid.  The cellulose with the pretreatment liquid may then be placed in an acetylation medium comprising acetic p  anhydride, sulphuric acid, unless sufficient is already present in the pretreatment liquor, and ethylidene chloride or another of the specified chlorinated compounds.  The amount of acetic anhydride may be 250-350 per cent of the weight of cellulose, and the amount of ethylidene chloride may be above 100 and even as much as 1,000 or more per cent of the weight of cellulose.  A low proportion of sulphuric acid may be used, e.g. one half to 2 per cent of the weight of cellulose.  Esterification may be carried out at 20 DEG -40 DEG  C.  The primary cellulose acetate may be ripened in the solution after adding water or alcohol.  The ripened cellulose acetate may be precipitated by incorporating with the solution a large volume of non-solvent, e.g. benzene. Precipitation may be effected or aided by removing part of the chlorinated compound by distillation.  A precipitating liquid at a temperature above the boiling point of the chlorinated compound may be used, e.g. water at or near 100 DEG  C.  The cellulose acetate or other cellulose ester obtained by the process, may be used in the production of artificial filaments, foils, and other extruded or moulded articles.

Title: Water-dispersible polymers
IPC: C08F279/02
Filed: 1964-04-07
Abstract: A cement mix comprises a dry blend of sand, cement, water-dispersable polymer and a sequestering agent which is the pentasodium salt of diethylenetriamine penta-acetic acid which is then homogenized with water and allowed to set.  The water-dispersable polymer is produced by spray drying a mixture of an aqueous ethyl acrylate/methyl methacrylate/methacrylic acid terpolymer latex, octylphenoxypolyethoxyethanol and calcium hydroxide.ALSO:A dry mixture of a particulate, water-insoluble, linear polymer and a water-dispersing agent therefore has polyvalent metal carboxylate groups disposed on the surface of the particles and chemically combined with the polymer and/or dispersing agent, which prevent coalescence of the polymer particles.  The mixture may be produced by incorporating polyvalent metal ions into an aqueous suspension of a linear emulsion polymer and which contains carboxylate groups of formula-COOM where M is H, NH4 or an alkali metal, in the polymer and/or dispersing agent, and removing all the water from the polymer. At least 3% of the polymer units may contain the carboxylate group and the mixture may also contain a sequestering agent for the ions of the above polyvalent metal, e.g. the pentasodium salt of diethylene-triamine penta-acetic acid, tetra-sodium ethylenediamine tetra - acetate, tri-sodium N-hydroxyethylethylenediamine tri-acetate, sodium polyphosphate and the sodium salt of poly(vinyloxyethylamine diacetic acid). In an example an aqueous ethyl acrylate/methyl methacrylate/itaconic acid terpolymer latex containing octylphenoxy-poly(40)ethoxy-ethanol and the half-amide/half-ammonium salt of a diisobutylene/maleic anhydride copolymer was treated with CaCl2 and the coagulated polymer was dried and pulverized. Other polymers exemplified are ethyl acrylate/styrene/methacrylic acid and ethyl acrylate/methyl methacrylate/methacrylic acid terpolymers and vinyl acetate/ethyl acrylate copolymer. Other dispersing agents exemplified are sodium dodecyl sulphate, sodium dodecylbenzene sulphonate, and a hydrolysed diisobutylene/maleic anhydride copolymer in its sodium salt form, and other flocculants are Ca(OH)2, Ba(OH)2 and Zn(OH)2.
