Patent GB-1370069-A (GB)
Title: Carburettor
IPC: F02M3/07
Filed: 1972-10-11
Abstract: 1370069 Spray carburetters FORD MOTOR CO Ltd 11 Oct 1972 [1 Nov 1971] 46825/72 Heading F1B A carburetter has a throttle 22 rotatably mounted across an induction passage and movable from a closed position 34 through an idle speed position 36 to a wide open throttle position, throttle control means including a plunger connected to a flexible diaphragm 50 which divides a hollow shell into two chambers 46, 48 each connected to the engine intake manifold by conduits 52, 54, a flow restrictor 88 in conduit 52 between a reservoir 90 and the manifold, a first spring 78 biasing the valve towards the wide open position and a second spring 70 biasing the throttle towards the idle position, arranged so that an increase of the manifold vacuum overcomes the second spring to move the throttle to position 37 and on engine shutdown the reservoir vacuum temporarily closes the throttle and decay of the reservoir vacuum permits the first spring to return the throttle to the idle position. When the engine is cranked, the turning of the ignition key energizes solenoid 98 to position valve 92 as shown. If the engine has been accelerated to move lever 38 away from plunger 62 and the accelerator pedal is released spring 40 biases the throttle 22 to the closed position 34. Inlet manifold vacuum increases and diaphragm 50 moves plunger 62 rightwards until the shoulder abuts sleeve 66 to move the throttle into position 37 permitting greater air and fuel flow sufficient to scavenge the combustion chambers. The subsequent vacuum decrease permits repositioning of the throttle into the idle position 36. When ignition is switched off solenoid 98 is de-energized thereby bleeding line 54 to atmosphere. Flow restrictor 88 delays the decay of vacuum in reservoir 90 thereby permitting the vacuum in chamber 46 to retract plunger 62 and closure of the throttle to position 34 to prevent "running-on". When the vacuum in reservoir 66 does decay the pressures in chambers 46, 48 equalize allowing the springs 70 and 78 to return the throttle to position 36.

Title: Improvements in or relating to bushings
IPC: F16F1/371
Filed: 1962-12-12
Abstract: 984,686. Bushings. DAYTON STEEL FOUNDRY CO. Dec. 12, 1962 [Dec. 12, 1961], No. 46899/62. Heading F2S. A bushing 10 for allowing relative movement between two members comprises a tubular resilient member 23 in which is embedded a rigid tube 25, preferably of steel, the tube being provided with a plurality of circumferentially spaced passages 30. In the construction shown the tube 25 possesses three axially spaced sets of passages, each set comprising five passages. The centres of two adjacent passages in a set subtend an angle of 90 degrees at the axis of the tube, the other three being equispaced with the outer two subtending an angle of 120 degrees at the axis. The external diameter of both ends of the bushing 10 is reduced so that in its mounting the resilient material will flow axially to fill the reduced portions. Resilient materials include natural rubber cured to have a hardness, Shore A, of 60 to 70 or a gum urethane stock. The bushing is mounted about a pin of a frame member of a vehicle and within a bore of the equalizer of a tandem spring assembly (Fig. 1, not shown), the outer surface of the pin or the surface of the bore being polished so that after a predetermined relative rotation of the equalizer and pin the bushing will slip over the polished surface.

Abstract: 1469673 Burning pulverulent material F L SMIDTH & CO AS 6 Oct 1975 [30 Oct 1974] 47021/74 Heading F4B A method of burning granular or pulverulent material similar to that described in Specification 1,434,091, but in which each of the units A and B operating in parallel have a first preheating stage and a last calcination stage 10a and 10b with fuel supplies 14a and 14b. The partly calcined raw material from units A and B is fed into a kiln 1 for sintering and then passes to a cooler 2. Heated cooling air leaving the cooler is divided so that part is led to the kiln for combustion of fuel therein, and part is led to the heat exchanger unit A. Exhaust gases from the kiln are fed to heat exchange unit B. The amount of heated cooling air is adjusted by fans 8a and 8b so that sufficient passes to the unit A for the calcinator 10a and sufficient passes through the unit B to support the burner 4 with enough surplus for the calcinator 10b. The extra air passing through the kiln resulting from the need to supply sufficient for both the burner 4 and calcinator 10b, ensures enough air flow to provide initial cooling of the clinker in zone C of the kiln before entry into the cooler 2. In a modified arrangement the calcinator fuel supply 14b may be dispensed with, and sufficient combustion is allowed of the burner 4 to support sintering in the kiln and partial calcination in the chamber 10b. Material from the chamber 10b is then led through a pipe 12b (Fig. 2) to the calcinator 10a. In a further modified arrangement each of the units A and B may be split into two units A<SP>1</SP> and A<SP>11</SP> and B<SP>1</SP> and B<SP>11</SP> co-operating in parallel (Fig. 3) or the unit A may be split into two units but the unit B remain as a single unit (Fig. 4).

The tower 1 has perforated gas inlet and outlet walls 2, 3 and is enclosed in a casing 4, 5 having different sized baffle plates 8 projecting towards the gas inlet wall 2 such that more gas passes through the higher regions of the tower than through the lower. Some of the purified gas may be recycled. Spent adsorbent is metered by a device 9 into a regeneration column 10 where it is washed with water fed from line 16a. Part of the H 2 SO 4  so formed is taken off at line 13 whilst part may be recycled via 15, 16. Regenerated adsorbent is then metered to line 19 where a stream of water takes it to hopper 20 and thence to the tower via line 21 whereas the water is filtered by a rigid conical filter and passed via line 22 to a hydrocyclone 23, where scum is removed before recycling. Fresh adsorbent may be automatically added by height adjustable container 33.

In a variable-speed planetary gear in which the planets 20 are driven from a sun wheel 24 by idler pinions 18 or sprocket chains and carry bucket wheels 32 which scoop liquid from an annular layer 54 around the periphery of the outer casing 14, the liquid 35 discharged from the buckets 34 enters a funnel 51, passes axially along the bores of the bucket wheel journals 22 and is exhausted to the drum 14 through radial openings 52. Each bucket wheel is surrounded by a shroud member 60 with inlet openings 66 normally registering with the spaces 64 between the buckets 34, but in the event of overloading ridges 68 projecting from the shroud into the liquid 54 set up a drag torque which rotates the shroud against loading springs 21 to close the inlet spaces 64. At the same time cams 70 force followers 74 into engagement with recesses 108 of cams 80 on the planets 20 and the coupling remains inoperative until the input torque falls to zero, when the springs 21 reset the shroud 60 to its open position for torque transmission. In the arrangement shown in Figs. 13 and 14 four bucket wheels are provided in compartments 150a ... 150d formed by radial walls 154, flow between the compartments taking place through openings 156 controlled by an axially movable disc 158. The drive to the planets is taken from a pair of axially separated sun wheels 24, 174, the latter being connected to the output shaft 28a through spur gears 176, 178, 180, 182 incorporating a one-way clutch 184. Control of disc 158 may be effected manually or automatically in accordance with torque and for speed.
