Title: Improvements in or relating to control means for tractor-drawn implements
Inventor: QUINTARD RAYMOND
IPC: A01B3/42
Filed: 1953-05-12
Abstract: 776,761. Agricultural implements. FERGUSON DE FRANCE SOC. ANON., H. May 12, 1954 [May 12, 1953], No. 13179/53. Class 6(1).  Plough bodies of a one-way plough are rotated about a longitudinal axis by means of an actuator operable by hydraulic fluid from a tractor power lift mechanism and controlled by an element movable from a neutral position to energize the actuator and automatically returnable to said neutral position as a result of the actuator movement. As shown in Fig. 1 a hydraulic cylinder 1 is provided with a doubleacting piston 2 which rotates a pulley on the rotation shaft 24 of the plough by means of a chain 5. A lever 22 is provided with a toothed sector 23 which co-operates with a pinion on the shaft 24 and is pivotally connected to a slide 26 which operates a hydraulic valve 16 controlling the piston 2. The upper end of the lever has a pin 27 whereby the lever can be moved manually or automatically into any of positions a, b, and any intermediate positions. Movement of lever 22 from position b causes the lever to fulcrum on the pinion and moves the slide 26 to cause pressure oil to flow through conduit 8 moving the piston to the right, rotating the shaft through 180 degrees and causing the slide to move the valve 16 into a neutral position. The shaft is rotated in the opposite direction by moving the lever 22 from position a to position b. In a modification the implement is connected to a tractor three-link hitch linkage and the lever 50, Fig. 8, is moved automatically on raising the implement by means of the hitch linkage by means of a roller which contacts the top link of the linkage and depresses a shaft having rack teeth which rotate a shaft which through pawls 40 rotates a cam 42 provided with a pin 46 which engages a slotted intermediate lever 47 pivoted to the top of the lever 50. The plough is automatically maintained in a vertical position by means of a pendulum 55 pivoted on a shaft and pivoted to the lever 47. Hydraulic dampers are provided to prevent lateral oscillation of the pendulum. In a further modification the lever is moved by a handle which is connected to a tumbler provided with a pin which engages a slot in the top end of the lever. The tumbler is moved from side to side corresponding to the positions a, b in Fig. 1. The extreme positions of the tumbler and thus the lever are determined by stops which are adjusted by means of a further handle. The adjustment of the extreme positions of the lever adjusts the angle of the plough which is engaging the soil. Specification 776,762 is referred to in the Provisional Specification.

Title: Process for the production of ª†-lactones of hexahydrobenzene and its homologues
Filed: 1931-05-08
Abstract: g -Lactones of hexahydrobenzene and its homologues, of the general formula <FORM:0378095/IV/1> wherein R represents hydrogen or alkyl and wherein one or more of the nuclear hydrogen atoms may be replaced by alkyl groups, are manufactured by the action of mineral acids, such as sulphuric or hydrobromic acid, in the warm, on a -(cyclohexanol-1)-fatty acid alkyl esters, obtainable by the Reformatsky reaction from a -halogen fatty acid esters, cyclohexanone or its homologues and zinc.  Alternatively the a -(cyclohexanol-1)-fatty acid esters are converted with water-eliminating agents into the corresponding b -g -unsaturated acid esters, which are then converted, with or without first being saponified, into the g -lactones by heating with mineral acids.  The products may be employed as agents against animal parasites, e.g. as anthelmintics.  They may be split up by lyes, and converted by careful acidification into the corresponding g -oxyacids, from which the g -lactones can be regenerated.  In examples: (1) a -(cyclohexanol-1)-butyric acid methyl ester (from cyclohexanone, a -bromobutyric acid methyl ester and zinc) is warmed with 70 per cent sulphuric acid, yielding the g -lactone of a -(cyclohexanol-2)-butyric acid; alternatively the oxyacid ester is converted by excess of 70 per cent sulphuric acid in the cold into a -(D <1>-cyclohexenyl)-butyric acid methyl ester, which is isolated and converted into the g -lactone by warming with 70 per cent sulphuric acid; (2) a -(cyclohexanol-1)-acetic acid methyl ester is gently boiled with 40 per cent hydrobromic acid, or is treated at 60-70 DEG  C. with 50-60 per cent hydrobromic acid, yielding the g -lactone of a -(cyclohexanol - 2) - acetic acid; (3) a -(cyclohexanol-1)-propionic acid methyl ester is gently boiled with 50 per cent sulphuric acid to produce the g -lactone of a -(cyclohexanol-2)-propionic acid; (4) the same reaction is carried out at 60-70 DEG  C., using 85 per cent sulphuric acid.  The product in each example may be converted by barium hydroxide into the barium salt of the corresponding acid, from which the lactone may be regenerated.
