Title: Improvements in liquor circulating devices for absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1924-03-06
Abstract: 212,572. Platen-Munters Refrigerating System Aktiebolag, (Assignees of Platen, B. C. von, Munters, C. G., and Tillquist, H.). March 8, 1923, [Convention date]. Refrigerating absorption machines and processes for. - The strong liquor flows from the absorber A through a pipe P into a vessel T, from which rises a capillary tube U leading to the top of the generator K. A chamber Q in the liquid space of the generator communicates through a pipe V with the vessel T, whereby upon the accumulation of generated gas in the chamber Q pressure is transmitted to the vessel T to raise the liquor through the capillarv tube. As soon as the lower end of the capillary tube is exposed the pressures in the vessels Q, T and the gas space of the generator are equalized, and liquor again flows into the vessel T and seals the end of the tube U, the process then being repeated. The pressure for raising the liquor may be obtained by heating the vessel T, in which case the vessel Q may be dispensed with and the vessel T and pipe U may be arranged within the generator. The weak liquor, under the superior head of liquid in the generator, flows through a pipe L passing through the pipe P to the top of the absorber, which is arranged in the cooling-tank @ of the condenser C. The absorber A and evaporator G are formed with cells F filled with loose material such as metal shavings E, and hydrogen or other inert gas circulates between them to equalize the pressure throughout the system. Specification 202,602 is referred to.

Title: Article handling arrangements
IPC: B65G47/49
Filed: 1974-02-08
Abstract: 1455775 Transferring irregular shaped articles between endless conveyers AMERICAN CHAIN & CABLE CO Inc 8 Feb 1974 [9 Feb 1973] 05804/74 Heading B8A Articles 20, which may be of bulky and of irregular shape are transferred under the surveillance of a control system, from a conveyer 12 to a sorter conveyer 16 with a sufficient pause in their travel for personnel to read coded information on the articles and enter it into a memory. This information causes discharge of the articles at preselected destinations by the sorter conveyer 16 by means not described. Flights 18 on the conveyer 12 operate a switch 114 which resets the control system for another cycle. Each object 20 is discharged from the conveyer 12 on to a ramp 40<SP>1</SP> and thereby obviates a photosensor 90. It then passes by gravity on to a vane 32 of a transfer rotor 28 and obviates a photo-sensor 92 which conditions the latter for rotation. The system controls the application and release of disc brakes 72, 74 on the rotor shaft 34 and the energization of a drive motor 56 for the latter. The rotor turns through 90 degrees to allow the article 20 to roll on to a ramp 42 on which it obviates a photo-sensor 94 and is engaged by a paddle 50 of a second rotor 30. The latter rotates through 180 degrees in an opposite direction to that of the rotor 28, and allows the article 20 to roll on to a series of laterally deflectable trays 22 of the conveyer 16. Operation of the rotor 30 is inhibited until the previously transferred article has cleared from contact with a sensor 96, by conveyance away on the conveyer 16. The rotor 30 has disc brakes 76 and 78, and has cam lobes 112 which operate switches 108, 110, and 176. The paddles 50 operate a switch 100. Cam lobes 106 on the rotor 28 operate switches 102, 104, and the paddles 32 operate a switch 98. A circuit is described by virtue of which the system cannot be energized until air pressure for operating the disc brakes is up to predetermined pressure, and the sorter conveyer 16 is running at correct speed (Fig. 5, not shown).

Abstract: 367,186. Tensioning belts and chains. COULSON, R., Glenmalure, Gibbet Hill, Coventry. Feb. 25, 1931, No. 5851. [Class 80 (.).] In belt or chain tensioning means of the kind in which a pulley or sprocket is mounted loosely on an eccentric A which is rotated on its fixed axle B by a spring C or weight and is prevented from reverse rotation by a ratchet and pawl detent, the detent E is self-contained and is removable without disturbing the main parts of the apparatus, so that it can be reversed to allow unhindered adjustment of the belt &c. and winding-up of the spring. The central part of the detent is splined on the shaft and carries the pawls engaging the outer ratchet ring R, the parts being maintained in self-contained relation by riveted washers L, M. Tongues K on the ring R engage slots in the casing, and the whole detent is retained in normal position on the axle by a split pin passing through the hole G. In order to indicate to the attendant that the detent is in reversed situation, the rivets F securing the washers L, M are extended so as to foul the spring C. Alternatively, the tongues K are dovetailed so that they will fully enter their slots only when the detent is in normal position, or the bore of the central part of the detent is coned to foul the run-out of the shaft splines. Spring tongues N on the washer M engage the ratchet ring R to provide a slight drag thereupon. A stop H may limit the eccentric movement.

Title: Improvements in or relating to the stretching of filaments, yarns, films and similar shaped articles comprising acrylonitrile polymers
IPC: D01F6/18
Filed: 1950-03-13
Abstract: <PICT:0682412/IV (a)/1> Filaments, yarns, films and similar articles are formed from a solution of an acrylonitrile polymer containing at least 75 per cent by weight of acrylonitrile in the polymer molecule, and, after treating the articles to reduce the amount of solvent carried thereby to between 0 and 1.5 per cent by weight, the articles are stretched while heated at a temperature of at least 100 DEG  C. When the proportion of residual solvent is reduced to the specified range, the articles may be stretched to a higher degree without rupture than when the proportion of solvent is higher.  Articles of greater tenacity are obtained.  The polymer may be a simple acrylonitrile polymer or it may be a copolymer of acrylonitrile and vinyl acetate, vinyl chloride, 2-vinyl pyridine, acrylic acid or its esters or homologues, styrene, isobutylene, or butadiene.  The acrylonitrile polymer may have a molecular weight of 10,000-750,000 or higher.  The residual solvent may be reduced to the specified range by washing with water, ethanol, isopropanol, glycerol, or ethylene glycol.  Yarns may be washed while travelling in a long length or while wound on bobbins. Wet-spun yarn may be washed in the gel state or after being dried. The washing treatment may require several hours or only a few minutes according to the temperature of the washing-liquid.  If desired, the residual solvent may be reduced by evaporation.  The spinning solution may contain dimethyl formamide or a mixture of nitromethane with formamide, formic acid, dichloracetic acid, or cyanacetic acid as solvent for the polymer. When the yarns or other articles are made by wet coagulation methods, the coagulating liquid may be water, glycerol, alcohol, ether or an aqueous solution of a salt, an alkali, or an acid.  As shown, acrylonitrile polymer yarn 2 proceeds from the coagulating bath 3 to a pair of mutually inclined rolls 4, 5, round which it passes in a series of helical turns.  The yarn passes to another pair of rolls 6, 7, which are partially submerged in washing-liquid in vessel 8.  The yarn is stretched between the two pairs of rolls. From rolls 6, 7 the yarn proceeds to rolls 9, 10 which are partially immersed in water at 100 DEG  C. in vessel 11.  The residual solvent is thereby reduced to not more than 1.5 per cent.  The washed yarn is passed to a heat-stretching zone.  It travels over steam-heated rolls 12, 13, and then through a heated tube 15 to a godet 14, stretching taking place between the rolls and the godet. During the stretching, the yarn may be subjected to dry heat, wet steam, saturated steam, or superheated steam.  Specifications 579,887, 595,044 to 595,054, and 603,873 are referred to.
