A hydraulic tappet comprises a cylinder 11 having one closed end, a choke ring 13 having a free sliding fit in the barrel and urged towards the open end by a spring 12, a valve having a head 14a coacting with the ring 13, an inner plunger 16 with a sealing ring 15 slidable on the valve stem 14d and confining a body of hydraulic fluid in the barrel, an outer plunger 18 secured to the stem 14d, a spring 17 between the two plungers 16, 18, and a snap-ring 20 holding the parts in the barrel. The plunger 16 maintains the ring 15 on top of the body of fluid in the barrel and on the upward stroke of the tappet to open the valve V a small amount of fluid leaks past the choke ring 13, causing slight shortening of the tappet, the valve 14 and plunger 18 moving slightly into the barrel and the plunger 16 and ring 15 moving slightly upwards to accommodate the fluid displaced by the valve stem. When the engine valve closes, the spring 17 moves the plungers 16, 18, apart to take up any clearance, whereby the valve 14 is moved away from the choke ring 13 which is moved upwards back into contact with the valve head 14a before the next valve-opening stroke. The plunger 18 is sealed by a resilient ring 19 and is press-fitted on the stem 14d, the upper end of which is provided with a recess for engagement by the engine valve stem. The hydraulic fluids used are preferably of high molecular weight with a viscosity between 50,000 and 1,000,000 centipoises, the fluid remaining flowable between -40‹F and 250‹F and its viscosity remaining substantially unchanged at temperatures between -25‹F and 250‹F. Examples of the materials used are petroleum oils, synthetic lubricants, diesters, polybutanes, polyalkanes, glycols and silicone polymers including silicone oils and the " bouncing putty " type of polymer. The hydraulic fluids may be mixed with oxidation inhibitors or viscosity modifiers. Specification 767,817 is referred to.

Title: Improvements in and relating to processes for dehydrating alcohols by azeotropic distillation and apparatus therefor
IPC: E06B3/90
Filed: 1932-11-17
Abstract: In dehydrating alcohol by the azeotropic method in which the ternary condensate obtained is separated into two layers one having a high content of extraction agent and the other a high content of water and low <PICT:0409791/III/1> content of extraction agent the latter is directly concentrated in a distillation column without previous separation of the extraction agent and the concentrated alcohol which contains some extraction agent in addition to water is returned directly to the dehydrating column.  Accumulation of the small content of methyl alcohol contained in the crude alcohol is prevented by withdrawing it from the top of the distillation column in the form of a binary mixture with the extraction agent.  Crude spirit is passed through a preheater J<1> and pipe I into a dehydrating column A from which the absolute alcohol is withdrawn through the preheater J<1> and cooler J<2> to storage. The alcohol is treated in the column with the azeotropic agent, e.g. trichlorethylene and the ternary vapour mixture passes off through a pipe 3 to a condenser D and cooler E and is then separated into two layers in a separator H the upper layer being of high water and alcohol content while the lower layer is of high entrainer content and is mainly returned to the column A through a pipe 7.  The upper aqueous layer which also contains the methyl alcohol is fed through a pipe 6 with a small proportion of the lower layer through a pipe 7<a> to a distillation column C. This latter is of greater length than usual, the number of concentrating plates being increased from 36 to 55 while refluxes are provided through pipes 8<a> 11<a> at the 36th and 55th plates respectively.  In this column the binary entrainer-methyl alcohol mixture passes off at the top and is condensed in coolers L, L<1>, some of the condensate being returned as reflux through the pipe 8<a> while the remainder is passed through a pipe 10 to a further distillation column where the entrainer is distilled off and anhydrous methyl alcohol obtained.  The concentrated alcohol passes off through a pipe 11 to condensers M, M<1>, from which reflux is returned through the pipe 11<a> while the remainder is returned through a pipe 13 to the dehydration column A.  A modification is described adapted for the direct treatment of mashes, worts and other dilute alcoholic liquors.
