Title: Improvements in linking machines
IPC: D05B7/00
Filed: 1959-09-10
Abstract: 882,261. Sewing machines. BECK, F. W., and BECK, K. J. July 22, 1960 [Sept. 10, 1959], No. 30911/59. Class 112 In a linking machine the looper comprises two elements which normally provide a closed bill for penetration of the loop of the needle thread on a first advance of the needle, and which move apart, on withdrawal of the needle, to spread said loop for its penetration by the needle on its next advance. As shown, a bracket 14 is fixed to the machine frame and is also fixed to a pair of spaced bars 26a, 26b which provide a slideway for a bar 25, to which is fixed a block 12. Mounted side by side in the latter is a pair of L-shaped looper elements 9, 10. The shank of element 9 is adjustably fixed in block 12, and the shank of element 10 is slidable therein. The feet 9a, 10a of said elements have respective lower and upper sloping edges 9b, 10b which are parallel to one another, and the upper edge of foot 9a is formed adjacent the tip with a shoulder 9c. The upper end of element 10 carries a pin 15 disposed in a slot 16 formed in one arm 17a of a double-armed lever pivoted at 18 to a bar 19 rigid with bracket 14. The other arm 17b engages a rotary cam. Element 10 thus reciprocates vertically to open and close a gap between the feet 9a, 10b. The bar 25 carries a roller 28 which engages a cam groove in a rotary member for reciprocating the elements 9, 10 horizontally. When the needle 3 advances through the groove in a point P 3  carried by a rotary dial 1, the closed bill constituted by the contiguous feet 9a, 10a penetrates and receives on the shoulder 9c the unopened needle thread loop b. When the needle withdraws, element 10 moves downwardly to open loop b into a triangular loop n It which is held open until the needle advances through the next point P 4  to penetrate said loop. Element 10 then moves upwardly to close the feet together, and the elements move away from the needle to leave the loop thereon. It is stated that the looper may alternatively be arranged scissors fashion.

IPC: C07J75/00
Filed: 1950-12-19
Abstract: The invention comprises (a) 1-methyl- D 6-dehydroestrogen compounds of the probable general formula <FORM:0715884/IV (b)/1> (wherein Rz represents hydrogen or an acetyl or propionyl residue, B represents C = O or CH - OR and R represents hydrogen or the residue of a fatty acid of not more than 6 carbon atoms or of an aromatic acid); (b) the preparation thereof by reacting a compound (obtainable by the process of Specification 715,883) of the probable formula <FORM:0715884/IV (b)/2> with acetic or propionic anhydride in the presence of p-toluenesulphonic acid at elevated temperature, or (where B is CH - OR) in the presence of sulphuric acid (preferably at room temperature), followed, if desired, by saponification; (c) the conversion of the unsaponified products of (b) to 1-methylequilenin compounds of the probable general formula <FORM:0715884/IV (b)/3> by dehydrogenation in the presence of a dehydrogenation catalyst or dehydrogenating agent, followed, if desired, by saponification. The 1-methyl- D 6-dehydroestradiol compounds of the invention (first formula, Rz = H, B = CHOH) are also obtainable by reducing the 1 - methyl - D 6 - dehydroestrone compounds (B = C = O), especially 1-methyl- D 6-dehydroestrone acetate (Rz = CH3CO), with lithium aluminium hydride.  In examples (1) D 1,4,6-androstatriene-3 : 17-dione is heated with acetic anhydride and p-toluenesulphonic acid to produce 1-methyl- D 6-dehydroestrone acetate; (2) the product of (1) is saponified to 1-methyl- D 6-dehydroestrone; (3) D 1,4,6-17-acetoxy-or-hydroxy - androstatrien - 3 - one is treated as in (1) to form 1-methyl- D 6-dehydroestradiol 3 : 17-diacetate; the p-toluenesulphonic acid may be replaced by sulphuric acid (the reaction being then preferably effected at room temperature); (4) the product of (3) is saponified to 1-methyl-D 6-dehydroestradiol, which yields a 3-monobenzoate by the Schotten-Raumann process; (5) the product of (1) is refluxed with selenium dioxide in glacial acetic acid or dioxan under nitrogen to produce 1-methylequilenin acetate; (6) the product of (5) is saponified to 1-methylequilenin; (7) the product of (3) is refluxed with selenium dioxide in glacial acetic acid to form 1-methyl-17-dihydroequilenin 3 : 17-diacetate, which may be saponified to 1-methyl-17 - dihydroequilenin - 17b  (also obtainable by reducing the product of (5) with lithium aluminium hydride).  Specification 715,939 also is referred to.

Abstract: 485,839. Preheating furnace charges. POLYSIUS AKT.-GES., G. Nov. 11, 1937, No. 30962. Convention date, Dec. 9, 1936. [Class 51 (ii)] In the preheating of granular materials on a gas permeable conveyer by furnace gases from the main heating process, part of the gases are drawn through the material on one part of the conveyer, while the remainder are used for heating air which is drawn through the material on another part. As shown, the space above the preheating-conveyer 1 is divided by a baffle 4 and the gases from the rotary furnace 2 pass in part down through the material on the conveyer from the space 5, and in part over the tubes of an air heater 7, through which air passes to the space 6 and thence downwards to the exhaust flue beneath the conveyer. A single exhaust fan may be used by connecting the flue 8 to the space beneath the conveyer.

A leaf spring 74, secured at one end to frame 14, has its other end 78 rolled around the pivot pin 80 to allow shifting movement thereof. An end of toggle element 66 abuts beneath a leaf spring 88 secured to the top of toggle element 70 and the stop member 94 on toggle element 70 engages a wear plate 98 secured to leaf spring 74 to limit the movement of the toggle arrangement as a result of small changes in the force applied to a ploughshare 20. A leg 60 of shank 22 is pivoted at 62 to a bracket on frame 14 to limit the movement of the ploughshare 20. A slotted bracket may be provided on plate 42 to limit the movement of the pivot pin 80. The leaf spring 74 may be omitted and the pivot pin 80 may bear against a helical compression spring and be secured to a tension link fixed to a pin on the plate 42.
