Title: Process for refrigeration and apparatus connected therewith
IPC: F25B15/10
Filed: 1929-07-27
Abstract: 338,935. Maiuri, G., and Bossini, R. F. May 31, 1929, [Convention date]. Refrigerating.-A mixture of fluids of different boiling points, e.g. ammonia and water, is heated in a generator and rectifier column 2, 1 to separate the fluids in gaseous form, the less condensible fluid passing from the top of the rectifier through a conduit 5 to a condenser 6 cooled externally, as by cooling water, whence it flows as liquid through a liquid seal 7 into an evaporator 8. Some of the more condensible medium in gaseous form is led from the generator to a nozzle 9 to induce a flow of mixed gases from the evaporator to a condenser member 10 preferably located in the rectifier and of fairly high temperature, whence the readily condensible medium returns through a seal 14 to the lower part of the generator. The less condensible medium of the mixture passes up into a further condenser element 11, 12 surrounded by the cooling water and is returned in liquid form through a seal 13 into the upper part of the rectifier. In the example shown an inert gas circulates through the evaporator and the condenser elements 10, 12, this gas being led in a cooled condition to the upper end of the evaporator. The inert gas may be used to balance only a part of the pressure differences, or in place of using inert gas the condensed refrigerant may be expanded through a valve in place of the seal 7, and pumps may be employed to overcome the pressure differences. Baffle plates are provided in the generator and rectifier, the lower ones 3 forming liquid head pockets sufficient to provide pressure head for the nozzle 9, while the upper ones 4 do not retain liquid. A heat exchanger for gasesentering and leaving the evaporator may be provided. The condensers may be fitted with plates over which the condensate flows slowly. In a modification the rectifier and condenser elements are in the form of coils, the upper condensers being air cooled and the lower one united, as by soldering, to the rectifier to exchange heat therewith. The rectifier coil terminates in a bell dipping into liquid in the generator so that a pressure head for the gas nozzle is obtained. The Specification as open to inspection under Sect. 91 (3) (a) mentions also the use of sulphur dioxide and carbon dioxide, and ethyl alcohol and methyl chloride as mixed fluids. This subjectmatter does not appear in the Specification as accepted.
Patent GB-692027-A (GB)
Title: Method of and apparatus for twisting yarn
IPC: D01H1/10
Filed: 1949-09-06
Abstract: 692,027. Twisting varns and cords. HOWE TWISTER CORPORATION. Sept. 6, 1949, No. 23103/49. Class 120(ii) A cord is formed by twisting a yarn around its source of supply and forwarding it to a takeup position, preferably in association with other yarns, where it is taken up within the orbit of a second balloon, whilst being given more than one twist per revolution about the axis of twisting. The supply and takeup devices are preferably twofor-one twisters and where two supply devices are employed, such as 20, 22, Fig. 2, these may be driven from an electric motor 38 by means of a belt 42, which also drives the take-up and cabling device 24. Yarns from devices 20, 22 pass upwards to a stepped capstan 33, positively driven from the spindle 152 of the cabling device 24. A pulley 248, influenced by a compression spring 252, tensions the yarns combined at the capstan 33 and before leaving the supply devices 20, 22, each yarn is tensioned separately by a tension device 100, Fig. 5, located above each hollow supply spindle 74. This latter tension is imposed by two slidable blocks pressed together by leaf springs 136, the pressure of which is adjustable by vertical movement of a sleeve 144. From the tension device 100, the yarn passes through the spindle 74 and a passage 84 formed in a disc 82 to the capstan 33. The disc 82 rotates with the spindle 74, but the tension device 100 and the bobbin supporting structure 86, along with a can 104 and a cover 106, are maintained substantially stationary by a weight 97, the device being held at an angle to the vertical when in operative position. The cabling device 24 has a rotary disc 174, Fig. 12, supporting a can 176 and a leg 180, which rotate with the spindle 152. An inner rotor 172 made of soft annealed steel is fixed to the spindle 152 and is surrounded by a permanent magnet 208 dependent from a base member 160 of a bobbin supporting structure 162 mounted on bearings on' the spindle 152, so as to rotate in association with the spindle against the winding tension of the yarn. A traverse mechanism 192 adapted to lay the yarn on the bobbin 37 is mounted on a frame attached to a disc 186 held substantially stationary by a weight 189, when the device is in its operative tilted position. The traverse mechanism is driven from the spindle 152 by a belt 198 and a worm 194 actuating a rack and pinion arrangement. Yarn passes from a pulley 322 of the traverse device to a presser finger 318 (not shown in full) held against the bobbin 37 by a leaf spring engaged with a ratchet wheel 310.

Title: Recovery of 5'-guanylic acid
IPC: C07H19/20
Filed: 1965-06-01
Abstract: Crystalline 51-guanylic acid dioxanate is obtained by mixing 1,4-dioxane with an aqueous acidic solution having a pH in the range 0.5 to 5 and containing 51-guanylic acid.  The dioxanate obtained is a solvate consisting of 1 mole of 51-guanylic acid, 1 mole water and 1 mole of 1,4-dioxane, from which 51-guanylic acid may be obtained by neutralization with alkali.  Generally about 16 times the theoretical amount of 1,4-dioxan per mole of 51-guanylic acid is used and combinations of 1,4-dioxane with other dioxane miscible solvents such as methanol may also be used.  A salt of 51-guanylic acid may be obtained by dissolving the dioxanate in water, neutralizing the solution with alkali, adding a water-miscible solvent, in which the salt is insoluble, to the solution and recovering the precipitated salt.  5-Guanylic acid may be recovered by this process from solutions of guanine and guanosine, from an aqueous phosphoric acid solution, from ribonucleic acid hydrolysates containing other 51-nucleotides such as adenylic acid, cytidylic acid and uridylic acid, or from aqueous solutions derived from fermentation broths.

Filed: 1946-08-06
Abstract: 639,773. Knitting-machines. STIBBE & CO., Ltd., G., STIBBE, E. V., and PALMER, G. Aug. 6, 1946, No. 23293. [Class 74 (ii)] In a two-feeder circular knitting-machine a jaw 2 coacts with a jaw 1 to form a trapper for a yarn or yarns from one feeder, and with a plate 3 to form a second trapper for a yarn or yarns from the other feeder. The jaw 1 is pivoted at 6 to a lug 7 on the plate, and from it depends a bifurcated lug 9 to which the jaw 2 is pivoted at 8. Pressure on the tail of the jaw 1, exerted through a lever 16 and adjustable screw 20 on a link 20, first swings both jaws, against a tension spring 11, to open the lower trapper, and then rotates the jaw 1 against a compression spring 10, to open the upper trapper. Each jaw is mitred or rounded at one end to facilitate entrance of the yarns. The trappers remain closed as the ingoing yarn is pulled out. A catch or shoulder 15 may be provided on the jaw 1 to retain yarn in the upper trapper when yarn is pulled out from the lower trapper in knitting from one feeder only. A recess in the plate 3 holds a pad of resilient material and the lower edge of jaw 1 is faced therewith. Coacting pivoted and fixed scissor elements 21, 22, common to both trappers, are pressed together by a plate spring 24 and are operated conjointly with the trappers, by the link 18. An incline 27 on an element 26 guides withdrawn yarns into the cutter. Slots 32, 33 in the plate 3 receive a main yarn and a splicing yarn during circular knitting, in the formation of Cuban heels, foot bottoms and other spliced areas, to prevent twisting or entanglement of the yarns.
