Filed: 1971-09-27
Abstract: 1365084 Shaft seals GENERAL ELECTRIC CO 27 Sept 1971 [29 Dec 1970] 44887/71 Heading F2B A shaft seal between two components which rotate relatively to one another comprises a sealing ring 28, Fig. 3, subject to relatively high pressure P1 of liquid or gas on one side and a lower pressure P2 on its opposite side, a radial seat 30 on one component for supporting the ring, a groove in the other component for receiving the ring, and means, such as a passageway 56, for connecting the high pressure side to the gap on the low pressure side between the end face of the ring and the wall 40 of the groove for generating a force on an end face of the ring which varies in response to changes in the dimension of the gap to centre the ring and reduce rubbing forces at the end face. As shown, the ring 28 is a split ring of carbon or metal and is held against a rotary outer shaft 32 by centrifugal force and inherent spring force. As regards the radial forces, an inward force is created by subjecting the outer periphery to high pressure through slots 44 and a groove 42 and subjecting the inner periphery to low pressure through vent holes 54. As regards the axial forces, high pressure acts on one end of the ring through a passageway 56 and the ring is balanced in the groove by the high pressure acting on the opposite end of the ring through orifices 52 and grooves 48. When the outer shaft is non- rotary, Fig. 10, the ring 72 is held against the stationary radial seat 76 by the high pressure acting on a lip 74. In Fig. 8, the ring 60 is a continuous ring and is sealed against the radial seat 66 by a split ring 64.

Temperature sensors 68, 69 responsive to air temperatures, and 70 to that of the aggregate as it leaves the drying zone 30, control burner 25 and conveyers 12 (13), so that the aggregate is just dry and at the correct temperature at the end of the drying stage. The dust is separated from the aggregate, trapped by the bitumen mist 55, and returned. A screw conveyer supported by the beam 45 (see also Fig. 3, not shown) may operate in either direction and may be used for sampling, or for supplying additives. In a modification, Fig. 4 (not shown), the drum has an internal restrictor cone (76) with internal helical blades (88) and an inverted U-shaped bitumen sprayer (82).  In another embodiment, Fig. 5, the drying and mixing drums 90, 91 are separate, the drum 90 having the burner 94 at the downstream end. Dried aggregate is discharged to the shoot 95 while dust is extracted by fan 111, separated at 96, and heavy dust passed to the silo 98, while air and fines pass through washer 100 where bitumen flows over surfaces 104, 105. The fines are entrapped therein and fed to the mixing drum, which is provided with an exhaust fan 110. A suitable proportion of heavy dust is also returned to the aggregate in shoot 95 by conveyer 99 under control of the operator.  The throughput in both embodiments is controlled by the drum inclination.

Title: Improvements relating to automatic battery charging apparatus
Inventor: CALE PHILIP EUSTACE
IPC: H02J7/00
Filed: 1968-09-27
Abstract: 1276505 Battery charging systems ALKALINE BATTERIES Ltd 25 Sept 1969 [27 Sept 1968] 46044/68 Heading H2H A battery charging system is provided with a reference cell. which is charged simultaneously with the main battery, together with means for comparing the voltage of the main battery with that of the reference cell, the comparison being used to terminate or to modify the charging process. A battery 10 of the sealed nickel cadmium type is charged from a supply 12, this type of battery exhibiting a rise in temperature and a fall in terminal voltage when it is fully charged. At the same time a reference cell 20 is being charged over a circuit which includes a diode 45, transistor 15 and a transistor 40 which together with a resistor 41 forms a constant current device. The transistor 15 with a transistor 16 forms a device for comparing the voltage of the battery 10 with that of the cell 20 since the bases of these two transistors are conditioned by the battery and the cell voltages respectively. As soon as the voltage of the reference cell 20 exceeds a certain value relatively to that of the main battery 10 a transistor 28 becomes conductive whereupon the transistor 16 becomes more conductive than the transistor 15 so that the current in this transistor falls and at a certain point no further charging current flows in the cell 20. When the main battery 10 becomes fully charged the fall in its terminal voltage causes the current in the transistor 15 to fall still further whereupon a transistor 47 becomes conductive which causes transistors 51, 55 to become conductive to energize a relay 30 to open contact 30/1 and terminate the charging process. The reference cell can then be discharged by closing a switch 60 which may occur automatically at the end of the charging process. Alternatively, energization of the relay 30 may be arranged to start a timer so that the charging process is terminated a timed period after the relay has been terminated. Again, the circuit may be modified so as to be usable to charge batteries which exhibit a rise in voltage when fully charged. A further embodiment shows a relay which is energized whilst the battery is being charged which relay has normally open contacts.

Abstract: 1,207,383. Fluid pressure brakes. B. J. CANFIELD, J. M. GRAHAM, and E. D. NEIL. 20 Oct., 1967 [20 Oct., 1966], No. 47938/67. Heading F2F. A vehicle emergency or parking brake comprises a conventional hydraulic braking system in which a conduit couples one or more master cylinders to brake actuators, the system being adapted by including a member within the conduit movable in response to action of an emergency or parking brake controller from a passive position to an active position, wherein pressure is applied to said brake actuators, the member being associated with means to limit the maximum pressure on the liquid when the member is in its active position. As shown in Fig. 6, fluid from a dual master cylinder 86 is fed via separate control cylinders 69 (Figs. 6 and 7) to diagonally opposite wheels of the vehicle. Valve 28 (Fig. 6) is normally opened so as to couple chamber 16 to the engine inlet so that air, entering a port 20 displaces a diaphragm against the force of a spring 26, deflecting rod 31 (Fig. 7) to the left so that valves 79 and 61 open, thus allowing fluid from the master cylinder 86 to flow via lines 87, 87<SP>1</SP> to one pair of brakes and via lines 91, 91<SP>1</SP> (Fig. 6) to the other pair. For parking or emergency braking, valve 28, mounted on the dashboard, is operated so as to admit air to chamber 16 so that spring 26 deflects rod 31 to the right, closing valves 79, 61 so that pistons 74, 54 apply a pressure of 750 p.s.i. to the brake cylinders. Valves 79 and 61 act as pressure relief and regulating valves. Fig. 1 (not shown) relates to a single system in which a vacuum booster (9) is interposed between the brake pedal and the master cylinder. The piston 34 (Fig. 2), enclosed in the control cylinder 32, includes a bifurcated member 43 loosely disposed in a bore 41 in the piston body 39 attached to the end of valve 31. The arms of member 43 are loosely disposed in slots in the body 39. Under normal conditions, valve 31 is displaced to the left by means of an inlet-operated diaphragm (Fig. 1, not shown) so that the feet of member 43 engage a nut 36 and open a ball valve 52, thus providing passage for hydraulic fluid through the bore 41 and allowing normal braking. For parking or energenoy braking, the valve 28 (Fig. 6) is operated so that air is admitted into the system allowing a spring 26 to displace rod 31 to the position shown in Fig. 2 and allowing spring 53 to close ball valve 52. This action also displaces piston 46 to the right so as to provide a pressure of 750 p.s.i. to the brake cylinders.
