Title: A fluid pressure actuator for modulating a valve in a flow passage
IPC: G05D16/10
Filed: 1957-02-19
Abstract: 860,671. Valves; fluid-pressure servomotorcontrol systems. GARRETT CORPORATION. Feb. 19, 1957 [Feb. 20, 1956], No. 5579/57. Class 135. A fluid-pressure actuated valve comprises a housing 10 having a passage 11 therein and a butterfly valve 14 engageable with a resilient sleeve 13 for controlling the flow of fluid through the passage. The butterfly valve 14 is connected to a piston 21 by a bell-crank 16 and is biased towards the closed position by a spring 27. The piston 21 is subjected to a reference pressure in chamber 30 derived from upstream of the butterfly valve 14 via a passage 34, filter 35, solenoid-actuated pilot shut-off valve 33 and passage 38. The reference pressure is controlled by a pressure-regulating valve 44. A restricted orifice 46 through the valve 44 permits pressure from chamber 30 to pass to chamber 47 and act on the face of a spring- loaded piston 48. Pressure in excess of a predetermined value forces the piston 48 upwards to uncover a port 49, thereby releasing pressure in chamber 47 and permitting valve 44 to lift and exhaust excess pressure from chamber 30 through passage 49a. On opening the shut-off pilot valve 33 the reference pressure forces the piston 21 into abutment with a second piston 25, at the same time opening the butterfly valve to its maximum position. Thereafter the two pistons act as a single unit, subjected on the upper face of piston 25 to pressure downstream of the butterfly valve via passage 32, variations in pressure downstream of the butterfly valve causing the combined pistons 25 and 21 to adjust the setting of the valve to maintain a regulated pressure.

Patent GB-1413694-A (GB)
Title: Fuel injection pump
IPC: F02D1/18
Filed: 1973-02-07
Abstract: 1413694 Shaft couplings AMBAC INDUSTRIES Inc 7 Feb 1973 5917/73 Heading F2U [Also in Divisions F1 and G3] A fuel injection pump comprises a pumping plunger reciprocable by a multi-lobed cam 32, a drive shaft 18 coupled to the cam 32 through an axially movable sleeve 52 internally and externally helically splined at 59, 54 to the shaft and cam, respectively, a chamber 112 pressurizable by liquid to cause axial displacement of the sleeve 52 and consequential adjustment of the injection timing due to the resulting change in the angular relationship between the shaft and cam, and a rotary valve which prevents the supply of liquid to the chamber 112 when the pumping plunger is performing an injection stroke. The rotary valve comprises permanently pressurized slots 92 in a stationary bearing liner 41, the slots being arranged to register with radial ports 94 in the cam 32 only when the cam 32 is in a position causing a return stroke of the plunger. The ports 94 are permanently connected to an annulus 100 in the shaft 18. A hollow spool valve 74 controls the supply and exhaust of fluid to the chamber 112. The position of the valve 74 is determined by centrifugal weights 82 pivoted at 84 to a spider 86 on the valve 74 and a spring 78 disposed between the valve and an abutment 88, 76 on a rod 72. The fully retarded position shown corresponds to idling speed, the spring 78 urging the rod to the right and the valve to the left. This causes the sleeve 52 to abut a shoulder 62, since the rod 72 and sleeve 52 are connected by a radial pin 64 which extends through slots 66 in the shaft 18. As the speed increases the valve 74 is moved to the right whereby an annular region 102 is simultaneously connected to the supply annulus 100 and disconnected from an exhaust annulus 114. Thus the chamber 112 becomes pressurized through ports 110, whereby the sleeve 52 and the rod 72 move to the left to increase the loading of the spring 78. This, in turn, tends to move the valve to close the annulus 100 until a balanced condition is reached. The pump plunger is rotated during reciprocation by a gear 28 which meshes with an end gear 30 coupled for rotation with the pump plunger. The gear 28 is mounted on a governor shaft 26 driven through gears 22, 24 from the drive shaft 18. In a modification, Figs. 7 and 8 (not shown), the pin 64 runs in a slot (130) in the rod 72, a spring (134) being provided for urging, via a piston (138), the pin 64 towards the right hand end of the slot (130). The modification is designed to cause additional retardation of the timing during starting.

Two eccentrics 35, mounted on the bearing 12, bear against abutments 37 detachably held by screws &c. to the strap-head for taking up wear &c., and also against the uppermost of a number of bowed leaf springs 34 loosely fitting on the squared portion of the member 13. The eccentrics 35 may be turned and locked by special devices in order to adjust the strap-head 11 up or down with respect to the bearing 12. The stationary die of the machine is shown at 1. In normal working, the springs 34 permit the die 2 &c. to yield as the crank-pin 6 passes its lowest position

Title: An improved process for converting tars rich in creosote into pitch, benzine and phenols
IPC: C10C1/04
Filed: 1931-02-26
Abstract: In a process for converting tars rich in creosote into pitch and other products, the crude material is heated for not more than a minute, at a temperature of 400-450 DEG  C. and a pressure of 20 atmospheres, the volatile products distilling off on releasing the pressure.  The phenol-rich oil mixture comprising the distillate is cracked at the same temperature and pressure and low boiling hydrocarbons formed are separated from the unattacked phenols by fractional distillation.  The phenol fraction comprising mainly carbolic acid and the cresols, is further freed p  from hydrocarbons by heating in the presence of dehydrogenating catalysts such as finely divided iron.  Phenol-poor crude materials may be enriched by the addition of phenol-rich fractions before cracking into hydrocarbons and phenols.

Abstract: 686,691. Brake adjusting devices. TUCK, A. W., and REECE, W. C. J. D. June 4, 1951 [June 10, 1950; June 10, 1950], Nos. 6160/50 and 14540/50. Class 103 (i). An internally expanding brake of the type in which the pivotal points of the shoes are moved automatically by a wedge or cone to adjust for lining wear, comprises a member 7, Fig. 2, having two members 9 sliding therein and adapted to engage the inclined faces of the wedge 12, the members 9 engaging at their other ends the parts 16 of the shoes. The base of the wedge is permitted lateral movement in the recess 14 and abuts against a screwed member 13. When lining wear takes place pressure is relieved on the members 9 and the screw 13 is rotated by the torsion spring 18 to adjust the pivotal centres of the shoes. Unequal wear causes the wedge to move laterally, and this retains equal clearances between shoes and drum, but rotation of the screw 13 is normally prevented by tension springs 21, Fig. 1. The shoes may be advanced by adjusters 20, as in Specification 499,020 which is referred to. In a modification, the wedge is formed in two parts which may be depressed by the movement of a rocking member positioned between the wedge and the screw 13, which rocker will move over to the side on which the greatest wear has taken place and thereby move the member 9 on that side. Specification 493,941 also is referred to, as being of the type to which the invention belongs.
