Title: Improvements relating to vapour electric rectifying apparatus
IPC: H02M7/08
Filed: 1924-11-19
Abstract: 246,615. Rowbotham, J. L., and Hewittic Electric Co., Ltd. Nov. 19, 1924. Vapour apparatus, arrangements of.-To avoid overloading a substation comprising vapour rectifying apparatus, provision is made for automatically reducing the voltage at the direct current terminals in the event of the load increasing beyond the normal capacity of the rectifiers. In applying the invention to a system in which one or more rectifiers 66 are supplied with a variable voltage controlled automatically in the manner described in Specification 246,614, a pair of relays 69, 70, the energizing coils of which are connected in series in the rectifier output circuit, are provided. The relays 69, 70 are so adjusted that, when the load increases beyond the capacity of the rectifier, the circuit normally controlled by the relay 16 is broken at 74, thus preventing starting of the regulating motor in a direction to increase the voltage. A further increase in load causes closure of the contacts 73 thus completing the circuit normally controlled by the relay 17 and starting the regulating motor in a direction to reduce the voltage. The resulting decrease in the load current restores the contacts 73, 74 to the position shown, thus restoring the controlling action of the relays 16, 17. In applying the invention to a system in which a variable number of rectifiers are adapted to be worked in parallel, in order to ensure that the amount of overload at which the relays 69, 70 become operative is varied according to the number of rectifiers in use, a number of additional windings normally connected across the direct current busbars are provided to assist the windings 69, 70, these additional windings being adapted to be de-energized successively as additional rectifiers are switched in. Provision may also be made for shutting down the rectifiers completely after a predetermined time interval if the overload persists. In other arrangements, the required reduction in voltage may be effected by a resistance arranged to be automatically interposed in either the alternating or direct current circuit when overload occurs.

IPC: C10L1/02
Filed: 1923-11-05
Abstract: Mixtures of alcohol and a liquid hydrocarbon are dehydrated and so made stable by treating them with a harmless and easily regenerated dessicant practically insoluble in either liquid. Preferably a small proportion of a liquid rendering the alcohol and hydrocarbon mutually miscible is added before dehydration. Liquid "combining" agents specified are ether, benzene and its homologues, propyl, butyl, and amyl alcohols and their homologues, and cyclohexanol.  Suitable desiccants are potassium carbonate, sodium carbonate, sodium sulphate, copper sulphate, magnesium chloride, and magnesium sulphate.  In an example a mixture of 80 litres of petrol, 20 litres of 95 per cent alcohol, and 2 litres of ether is passed through a series of 6 vessels charged with potassium carbonate mixed with inert material such as pumice.  The strength of the alcohol is thus raised to 99.7 per cent.

Title: Hydraulic apparatus for tractor drawn implements
IPC: A01B63/10
Filed: 1952-11-06
Abstract: 772,171. Tractor power-lift mechanisms. MASSEY-HARRIS-FERGUSON, Inc. Nov. 6, 1952, No. 27944/52. Class 79(1). In a tractor hydraulic power-lift mechanism a thrust linkage 53, 54 is pivotally connected at one end with the draft links 21 and at the other end connected to control-valve operating mechanism whereby the pressure in the ram cylinder 14 is progressively increased as the links 21 rise until the control valve 27 is automatically returned to its neutral position. The invention is applied to the type of tractor power-lift mechanism comprising the draft links 21 connected by drop links 20 to arms 19 on a rock shaft 18 having an arm 17 connected by a rod 16 to a piston 15 in the cylinder 14, the cylinder being supplied with fluid pressure through a pipe 26 from an engine-driven pump 24 and a sump 25, the pipe 26 serving as an exhaust conduit for fluid in the cylinder during lowering of the links, the valve 27 controlling the supply of fluid and exhaust of fluid from the cylinder and being under the control of a floating lever 40, the lever being acted on by a spring 43, carrying a pad 41 engageable with an eccentric pin 42 on a manual controller 32 and having a pivotal connection at 44 with a member 39. The member 39 is connected to a rod 35 pivotally connected to a shackle 37 pivoted at 38 to the tractor, and a spring 36 is arranged between the tractor and a collar on the rod 35. In this type of mechanism an upper link (not shown) is pivoted to the shackle, and together with the links 21 may support an implement, variations in draft load controlling the valve 27 from the upper link through the members 37, 35, 39, 40. In order to supply fluid to an auxiliary actuator 45 on an implement whilst maintaining the required pressure in the cylinder 14 the upper link is removed and the shackle 37 carries the thrust linkage comprising a threaded rod 54 slidably received in a sleeve 53 carried by a drawbar 55 detachably carried by the links 21. The rod 54 adjustably carries a nut 57 against which the sleeve 53 abuts during raising of the links, thereby tending to move the rod 35 against the action of the spring 36, such movement causing the rod 39 to pivot the lever 40 by a projection 59 engaging the skirt of the piston 15 or the cylinder, depending on their relative positions, thus controlling the valve 27. The effect on the hydraulic system is such that the longer the combined lengths of the members 53, 54 as determined by the position of the nut 57 the higher the pressure in the pipe 26 and cylinder 14. The pipe 26 has a branch 49 which can be connected by a three-position valve 50 and a pipe 51 to the auxiliary actuator 45, and in another position of the valve 50 the pipe 51 is connected to the reservoir 25 through a pipe 52. In a modification (not shown) the three-position valve is replaced by a simple cut-off valve by opening of which the auxiliary actuator can be pressurized, the actuator being retracted by movement of the hand lever.
