Title: Abutment assemblies for internal shoe drum brakes
IPC: F16D65/22
Filed: 1973-08-29
Abstract: 1470525 Internal shoe drum brakes; wear adjustment GIRLING Ltd 29 Aug 1974 [29 Aug 1973] 40702/73 Heading F2E An abutment assembly is disposed between adjacent ends of the two brake shoes of an internal shoe-drum brake, a double ended hydraulic actuator being positioned between the other shoe ends; the assembly comprises tappet assemblies 6, 7 with respective abutment members 8, 12 for engagement with the shoe ends and force transmitting means for transmitting forces between the members 8, 12 and comprising a plurality (e.g. eight) of force transmitting finger members 9 pivotally supported between and engaging the abutment member 8 and an output member 16 in force transmitting relation with the abutment member 12 via a spindle 13; each member 9 is so orientated that with a brake application during forward rotation of the drum only part of the input force applied to member 8 is transmitted to member 12. As shown, the radially outer end of each finger member 9 is received in an annular cage 10 seated against an internal shoulder 3 in a bore 2 in a housing 1 of the assembly. Each finger member 9 has a pair of spaced curved portions 18, 19 which bear respectively against the cage 10 and the output member 16. The radially inner and outer ends of each member 9 are curved as at 22, 23 to form arcs of the same circle, these ends engaging the end 13a of spindle 13 and the cage 10 respectively to restrain and support the member 9. In the inoperative condition of the assembly illustrated the abutment member 8 engages flat portion 24 on the members 9. However, when the brake is applied with the drum rotating in the forward direction the abutment member 8 is moved to the left, the finger members 9 pivot about portions 18, 19 and curved portions 20 adjacent the flat portions 24 engage the abutment member 8. A reduced force is transmitted through the collar 16 and spindle 13 to the abutment member 12. When the brake is applied with the drum rotating in the reverse direction, the force on member 12 is transmitted through the spindle 13 and the collar 16 to the finger members 9 which are prevented from pivoting by engagement of portions 20 with the member 8, and thus the full force is transmitted to abutment member 8. Force reduction in the reverse direction is obtained by modifying the tappet assembly 7 similarly to the assembly 6. The assembly could be modified to utilize fixed pivots instead of the curved surfaces acting as fulcrum surfaces. As shown the spindle 13 is axially movable relative to a gear 11 which forms part of an adjuster mechanism.

Patent GB-1071857-A (GB)
Title: Improvements in or relating to apparatus for removing liquids from bulk containers
Inventor: THOMPSON JOHN ANTHONY
IPC: F04D9/00
Filed: 1963-10-17
Abstract: 1,071,857. Emptying tanks. AVERY HARDOLL Ltd. Oct. 5, 1964 [Oct. 17, 1963], No. 40969/63. Heading B8T. [Also in Division F1] In apparatus for removing liquid from a bulk container, e.g. a ship's tank, through a suction pipe 12, an inlet fitting 13 at the bottom of the container through which the liquid enters the suction pipe has an opening the height of which above the bottom of the container is decreased automatically in response to downward movement of a float 34 supported by the liquid, and the suction exerted in the pipe 12 is controlled by means responsive to changes in said suction and acting to control the speed at which a pump 18 producing the suction is driven. Thus the entry of entrained air is reduced so that measurement of the volume of liquid withdrawn can be satisfactorily effected by meters. Control of height of inlet opening, Fig. 3.-As the float 34 falls, an arm 32 mounted on a fixed tube 24 of the fitting 13 moves downwardly causing the plunger 38 of a control valve 36 attached to a sleeve 25, vertically slidable in the tube 24, to move downwardly and connect ports 42, 43 of the valve with a liquid pressure source and a liquid reservoir, respectively. These ports 42, 43 are connected by conduits 44, 45 to the upper and lower ends of a doubleacting servo motor 28 and thus the plunger 29 of this motor moves downwardly causing the slidable sleeve 25 to which it is attached by a spider 31 to move downwardly and reduce the height of the inlet opening. Baffles (not shown) may be provided around the fitting 13. Suction pump speed control, Fig. 5.-As the height of the inlet opening reduces, the suction produced by the pump 18, which is driven by an internal combustion engine 22 supplied by a fuel injection pump 23, increases. This reduces the pressure in a chamber 66 of a slide valve 62, to which the pump 18 is connected by a conduit 67, producing a pressure difference across a diaphragm 63 and causing the slide valve to operate and in turn operate a liquid pressure servomotor 56. The servomotor 56 is connected via its plunger rod 55 to a throttle lever 53 which in turn is connected via a link 57 and a lever 58 to a control rack (not shown) on the injection pump 23. Thus when suction increases the injection pump reduces its fuel delivery to reduce the engine speed thus producing a compensating reduction in the suction of the pump 18. The engine 22 may be replaced by a prime mover driven at a constant speed, the speed of the pump 18 being varied by a variable-ratio transmission gear. From the pipe 12, the liquid passes through a filter, the suction pump 18, an air separator, and finally a meter.

Title: Nuclear reactor fuel preparation
IPC: C01G43/025
Filed: 1958-12-30
Abstract: The fuel for a liquid fueled nuclear reactor comprises a suspension of uranium dioxide in bismuth.  The fuel is formed by heating a mixture of bismuth oxide, bismuth and uranium in a scaled steel capsule.  The temperature maybe either that of the melting point of the bismuth oxide or that at which the uranium is soluble in the bismuth.  The conditions are selected such that uranium oxide, UO2, only is produced and not the non-stoichiometric compound of the oxide.  The latter is not wetted by bismuth and does not easily disperse in it.  The amount of bismuth oxide employed is less than that theoretically required because of the oxygen available in the free space of the capsule and the reaction of some of the uranium with the material of the capsule.

Abstract: <PICT:0900553/III/1> Hydrocarbons are cracked in a fluidized bed of solid material, preferably cracking catalyst, which is supplied with freshly regenerated solid from an elevated regeneration zone by introducing a first hydrocarbon feed into the bed to contact the freshly regenerated solid immediately on its introduction to the bed and separately supplying a second hydrocarbon feed into another portion of the bed.  Catalyst from the regenerator 4 descends to the reactor via one or more standpipes A and C.  By means of the hollow plugs 36 the streams of catalyst are directed into annular streams into which feed is introduced through the outlets 34 in the plugs.  A second feed which may be the same as that introduced via the plugs or may be a high boiling fraction of the original feed, the lower boiling fraction being introduced via the plugs or may be a cycle stock is introduced to the bed via inlets 44.  Steam may also be introduced with any of the feeds. Preferably cycle stock is introduced at inlets in quadrants other than those containing standpipes A and C and, if desired, the quadrants may be separated by slotted baffles.  A fluidizing gas is introduced through distributer 40.  Catalyst passes through slots into the stripping well 10 to which stripping gas is fed by distributer 20.  The stripped solid is then carried by a gas, which preferably contains some of the oxidizing gas for the regeneration and is introduced through hollow plug 16, up the riser B to the regenerator to which further oxidizing gas is fed by distributer 24.
