Title: Process for producing 1-acyloxy-3-butene-2-ones
Filed: 1948-09-29
Abstract: 1-Acyloxy-3-butene-2-ones are made by subjecting 1-acyloxy-4-hydroxy-2-butyne to the action of a mercuric ion catalyst in the presence of an inert solvent.  The term "acyl" is defined as RCOO where R is a hydrocarbon residue of a fatty acid.  Specified solvents are acetone, water and aqueous and glacial acetic acid. Catalysts specified are mercuric sulphate, mixtures of mercuric oxide and boron trifluoride and mercuric sulphate in sulphuric acid.  Half esters of acetylenic diols described in Specification 25568/48 (as open to inspection under Sect. 91), may be used as butyne reactants, e.g. half esters of lower aliphatic and higher fatty acids many of which are specified.  With half esters of lower aliphatic acids which are preferred the reaction is exothermic but with higher fatty acid esters heat may be necessary, a temperature of 100 DEG  C. being given.  In an example, 1-acetoxy-2-butyne-4-ol is dissolved in acetone containing mercuric sulphate and stirred for 4 hours, the temperature rising to 60 DEG  C. when after treatment with charcoal, filtration and vacuum distillation 1-acetoxy-3-butene-2-one is obtained.

Abstract: 837,782. Slot insulating machines. SMITH, V. K. Aug..12, 1957, No. 25444/57. Class 35. A machine for feeding strip insulation into core slots has a radially reciprocating inserter and the core support is indexable a slot pitch at a time. The strips and the inserter are of greater length than the slots. As shown, strip S from a reel 73 passes between rolls 80, 81 that form crease lines about # inch from the edges, then through rolls 82, 83 that bend the edges down ninety degrees, thence to vertical spindle rolls 84-85, 86-87 that turn the edges inward, first 45 degrees then 90 degrees. The cuffed strip then reaches feed rolls 88-89 of which roll 89 is driven through a one-way clutch from gear 52 meshing with a rack 51 and is passed to a reciprocating shear blade 43 on a slide 42 carried by a gear rack 41 meshing with a gear on the main shaft 25. The severed length is under a pin 66 on a carriage 65 which arrests the strip with its centre above slot 34 in a platen 35 the carriage being raised from the strip on its return stroke. The inserter blade 33 which pushes the strip through slot 34 into the core slot is on a slide 32 fixed to a rack 31 meshing with a gear on shaft 25 and has wings 131 for flaring out the ends of the strip, the spreading apart thereof being facilitated by compressed air fed via inlet 134 into passages in the blade when it is near the lower end of its stroke. The core B is readily mountable on a shaft driven through a one-way slip clutch and a gear 56 meshing with rack 55 this shaft being locked in successive positions through a linkage which forces a plunger into one of the notches of starwheel notched to match the core B. The source of power is a pneumatic cylinder 20 which moves shaft 25 angularly through rack 23 and gear 24, the racks 51 and 55 being driven from this shaft by a third member 50 (Fig. 8, not shown) of this triple rack, a lost motion connection intervening between racks 50 and 51, rack 50 meshing with gear 40 (Fig. 8) which also operates rack 41.
