Filed: 1938-06-14
Abstract: 519,158. Mechanical presses. FAWCETT, Ltd., T. C., FAWCETT, D. L., and BOTTOMLEY, A. E. June 14, 1938, No. 17597. [Class 87 (ii)] [Also in Group XXIV] In a press of the type wherein a plunger cis actuated by a screw b provided with a friction disc e driven in one or other direction. by two friction plates f, g on driven shaft h,this shaft' is moved axially by a lever j pivoted at one end to a boss on the shaft and at the other end to an arm k pivoted on a shaft m which carries a cam member. o, Fig. 3, disposed in a fixed housing n. Between a liner p and the cam o there is a gap r which tapers towards the centre. Two balls or rollers s are situated in the gap r and spring-urged followers t tend'to force the balls towards the narrow portion of the gap to lock the cam o against rotation. A handle u is loosely mounted on the shaft m and carries a lateral projection u<2> which extends into the gap r between the balls s. When the handle is turned it first moves one ball s against the action of a follower t until the ball strikes a shoulder o<1> on the cam. Further movement rotates the cam and thus operates the shaft h to start the press. The other ball is then moved up by its follower to lock the cam against rotation. At the lowest point of the press stroke, an adjustable stop c<1> comes into contact with a projection u<2> on the handle and turns it in a backward direction, thus reversing the press. The shaft m also carries arms v which are connected by chains v<1> to two guard members w in the front and rear of the press which slide on rods w<1> so that the guards are raised when the handle is operated to start the press.

Patent GB-1601610-A (GB)
Title: Trace acid removal from liquid hydrocarbons
IPC: C10G19/02
Filed: 1978-05-04
Abstract: For removing acids from liquid hydrocarbons, these are treated with an aqueous base. The mixture of liquid hydrocarbons with the aqueous alkali is introduced into a bed which contains a hydrophilic medium, so that the aqueous phase droplets present in the hydrocarbon phase coalesce to form larger drops and thus settle out of the hydrocarbon phase. The coalescence medium used is preferably activated carbon or anthracite, bituminous coal or lignite. Due to the intimate contact between the aqueous base and the liquid hydrocarbon in the bed of the medium, not only high utilisation of the base is achieved, but a high concentration of salts of the acids removed from the hydrocarbon, for example naphthenic acids, is also obtained in the aqueous phase, so that the acids in question can be recovered as a by-product of the process.

Title: Improvements in or relating to power transmission mechanisms
IPC: F16D7/04
Filed: 1933-06-22
Abstract: 409,152. Slipping clutches; variable-speed gearing. MORLEY, C. C., 181, Castle Road, Salisbury. June 22, 1933, No. 17747. [Class 80 (ii).] A power-transmission mechanism comprises three series of arms 5, 6, 7 pivoted on a driving-flywheel 2 and pressed by leaf-springs 8 into engagement with three four-lobed cams 12, 13, 14 rotating with a driven-member 15 and capable of angular movement relative to each other to vary the maximum torquesetting under centrifugal or manual control. Under all but light loads, the arms ride over the cams to impart an impulsive drive to the driven element with the assistance of the kinetic energy stored in the flywheel 2 during the idle passage of the arms down the rearward slope B of the cams, which is twice as long as their useful forward part A. With all the cam lobes at the same angular position the idle stroke, and so the maximum torque, are at their maximum values. The minimum condition is obtained with the lobes equally spaced as shown dotted in Fig. 2. The central cam 13 is fixed to the driven-member 15, and the angular position of the outer cams 12, 14 is simultaneously varied through bevel and worm gearing 21, 23 by turning a spindle 25, which may be effected through further worm-gearing by manual axial movement of a circular rack turning with the driven shaft. Automatic centrifugal means for turning the spindle 25 comprise a V-shaped yoke 32, Fig. 3, freely mounted on the spindle 25 and carrying a toothed wheel 31 turning with a wheel 29 in mesh with a wheel 28 secured to the spindle 25. The yoke is urged outwardly by a centrifugal weight 34 against the resistance of a tension spring 35. Upon a fixed member near the yoke are two projecting pins 38, 39, with either of which the toothed wheel 31 comes into engagement at its inner or outer extreme positions, so as to turn the wheels 29, 28 and vary the maximum torque setting. Secured to the cam 12 are two further pins 41, 42 so arranged that in the minimum torque position the pin 42 strikes a projection 40 on the yoke 32 and pivots the yoke until its toothed wheel 31 is out of range of the fixed pin 38, which position is maintained until increased driving resistance reduces the speed and allows the yoke to be pulled into the range of the fixed pin 39. The pin 41 has the reverse effect. The mechanism is reversible, but a flywheel is always arranged on the driving-shaft.
