Title: Production of ferrocene compounds
Inventor: CORDES HANS
IPC: C07F17/02
Filed: 1962-12-13
Abstract: Ferrocene compounds are prepared by reducing ferric chloride with iron in an organic solvent for the ferric and ferrous chlorides, treating with a strong base and cyclopentadiene or an alkyl cyclopentadiene, preferably in the absence of oxygen, and separating the ferrocene compound from the reaction mixture.  The alkyl cyclopentadienes (specified) have alkyl groups of 1-4 C atoms and methylcyclopentadiene is preferred.  The ferrous chloride which may be used in excess, e.g. up to 20 mole excess, may be reduced in acid solution, acidified using a mineral acid, e.g. HCl, H2SO4, H3PO4 or an organic acid, e.g. formic, acetic, propionic and oxalic acids which may be used in concentrations 10-6 to 1 mole per litre.  The organic solvents should be such that at least 1% and preferably at least 10% by weight of the ferric and ferrous chlorides are soluble. Suitable solvents are water-miscible solvents such as primary, secondary and tertiary aliphatic alcohols, polyhydric alcohols, carboxylic acid amides, carboxylic acid nitriles and solvents having slight water solubility such as esters of lower aliphatic carboxylic acids (specified), but the preferred solvent is methanol.  The strong base may be diethylamine, piperidine or an alcoholate of an alkali metal, e.g. sodium methylate, sodium ethylate and sodium n-propylate, which if an alcohol is used as the solvent, may be prepared from the same alcohol. The alcoholate may be added as a solid, a slurry or a concentrated solution.  It is advantageous to stir the reaction mixture after addition of the base for 1-30 mins.  The reaction may be carried out at 0-200 DEG  C. and thus the reaction is complete in 0.5-8 hours.  If the solvent used is miscible with water then the reaction mixture may be worked up by adding it to a dilute aqueous mineral acid from whence the ferrocene compound may be filtered off, washed with water and dried.  If, however, the solvent is only slightly miscible with water it may be removed by distillation together with any volatile base present and the ferrocene compound separated from the residue by sublimation, recrystallization or steam distillation.

Filed: 1963-12-02
Abstract: 1,076,497. Endless conveyers. RICHARD SUTCLIFFE ENGINEERING SYSTEMS Ltd., and E. BOTTOMLEY. March 2, 1965 [Dec. 2, 1963], No. 47544/63. Heading B8A. [Also in Division G3] A tensioning control of an endless conveyer comprises a valve 22 controlling an hydraulic motor 21 which drives a winch 16 to wind or unwind a rope 17 which passes around pulleys 14, 18, 15, 19 and 20 and is connected to a weight 9. The conveyer belt passes round a roller 6 in a carrier 7 and the belt tension acts on a spring-loaded lever 24 carrying the pulley 18. Thus variations in the tension of the belt causes the rope to rotate the lever 24 to actuate the valve 22, an indicator 28 being provided. The weight 9 is below the normal datum setting of the tension and when the system first starts up, the winch tends to pay out rope to reduce the tension existing in the belt and this can be taken up by the weight 9. If the weight 9 is below its upper level in the cage when the system stops, the weight moves to its top level to compensate for the tension.

Title: Hydraulic thrusting device
Inventor: ASHTON PHILIP ERNEST
IPC: F15B15/18
Filed: 1967-10-19
Abstract: 1,200,772. Hydraulic presses. P. E. ASHTON. 19 Oct., 1967 [24 Oct., 1966], No. 47595/67. Heading B5F. [Also in Division B3] An hydraulic device such as a press e.g. for rivet heading, staking or marking, includes a pump 31 for feeding fluid under pressure from a reservoir 89 to a movable ram 16, the pump being carried by and movable with the ram, and actuating means operated manually for moving the ram into engagement with a workpiece and for thereafter actuating the pump to supply fluid under pressure to the ram. In the example shown the actuating means comprises a hand operated lever 17 pivoted at 20 to a bracket 19 and at 70 to a crosshead 46 secured to a piston-rod 38. The lever 17 is releasably connected to the ram 16 through a spring- biased latch pin 76 having a tongue 82 which is bevelled to match the walls of a groove 81 in the ram 16. Downward movement of lever 17 will thus carry ram 16, a piston 23 and pump 31 together in the same direction. During this movement fluid is drawn from the reservoir 89 through a check valve 29 and into cylinder 22 above piston 23. When the ram 16 meets an obstruction the latch pin 76 will be forced out of groove 81 and will drop into a slot 72 in ram 16 to allow free operation of the parts involved. Continued movement of lever 17 will bring a bushing 51 (Fig. 4), into sealing engagement with an 0-ring 50 carried by an annular piston 47. Downward movement of bushing 51 and piston 47 will force fluid through ports 36 into an annulus 42 and on into cylinder 22 to apply hydraulic pressure to piston 23 and ram 16. At the same time fluid is being drawn past a ball valve 57 into a barrel 32. On reversing the motion of lever 17 piston-rod 38 will move bushing 51 away from ring 50 and allow a cruciform washer 52 carried by rod 38 to engage piston 47 and carry it upwards. Fluid in barrel 32 will thus pass to the underside of piston 47 through a central passage 48 and become available for displacement into cylinder 22 upon further reciprocation of lever 17. To release the ram and raise it, lever 17 is moved upwardly to cause the tongue 82 to re-enter the groove 81, the tip of piston-rod 38 unseating valve 57. In a simplified embodiment (not shown) the valve unit 55 is omitted, giving a short single stroke hydraulic press without locking facility.

Title: Improvements in or relating to brake control for web roll stands and the like
IPC: F16D65/28
Filed: 1965-11-12
Abstract: 1,073,269. Feeding webs. M. D. MARTIN. Nov. 12, 1965 [July 21, 1965], No. 48019/65. Heading B6B. [Also in Division F2] In a self-propelled, web roll transporting stand having a pair of hydraulically operated lifting arms with hydraulically braked chucks, an automatic brake control is provided in which the hydraulic brake pressure is controlled in accordance with decrease in weight of the web roll due to a decrease in diameter thereof. With the web roll 12 clamped in the chucks, hydraulic jacks 6 are supplied with highpressure fluid via a manual valve 11 to raise the pair of arms 1. When the arms 1 are raised to the working position, a detector 14 opens a bleed valve 13 in the hydraulic lifting circuit, whereupon the manual valve is operated to close the circuit. A hydraulic sensor 24 is incorporated in the lifting circuit, the piston 25 of which is pivoted at 27 to a balanced arm 20. As the weight of the web roll 12 decreases, so will the hydraulic pressure in the jacks 6, resorting in movement of the balanced arm 20. The hydraulic brake circuit includes two brake cylinders 19, a pressure regulator 31 having its piston 29 pivoted to the balanced arm 20, and a master cylinder 46 which is manually adjustable to preset the braking torque. Movement of the balanced arm 20 controls the braking torque via the pressure regulator 31. The balanced arm 20 is initially balanced in a predetermined attitude by an adjustable spring 39. The weight of the average web roll is substantially proportional to the square of the diameter of the web roll. To compensate for the change of this square function as the web roll diameter decreases, the balanced spring 39 exerts its pull through toggle links 36 and 37.
