Title: Improvements in and relating to automatic brake controls
IPC: B60T8/40
Filed: 1923-12-03
Abstract: 220,863. Harrigan, L. T. Dec. 3, 1923. Automatic speed control. - The brakes of an automobile are applied at a predetermined excessive speed by a governor controlling the valve of a brake system in which fluid normally kept in idle circulation by a pump can be transferred from one side of a brake piston to the other to effect the application of the brakes. A gear wheel pump 36 normally circulates fluid in a circuit comprising pipes 19, 26 and a valve 41 the stem of which is connected to a centrifugal governor 32 mounted on the shaft 33 of one of the pump rotors. The shaft 33 is driven from the driving shaft of the vehicle. The chambers on the two sides of the brake piston 9 are connected to the fluid circuit by pipes 18, 26<1> so that when, in the event of excessive speed, the valve 41 is closed by the governor, fluid will be transferred by the pump from the front side of the piston 9 to the rear side thereof, thereby applying the brakes. The piston 9 is arranged to actuate the existing brakes by the provision of a cross-piece secured to the brake rod and passing through a longitudinal slot in the rod of the piston.

Abstract: 177,562. Bunn, C. W. July 30,1921. Hoods. - Relates to hoods for road vehicles, of the type in which the cant-rails contract towards the pillar hinges on turning down and in which the cant-rail plate and pillar plate are connected by a substantially horizontal link and a lever pivoted to both and to the supporting-strut, which is also hinged to the pillar plate at its lower end. and consists in forming the pillar plate in two relatively adjustable parts. The cant-rail plate 2, Fig. 3, is connected to the upper pillar plate 4 by a link 8 and by a lever 14, the cant-rail having a limiting shoe 13. The lever 14 has an arm 15 pivoted to a strut 16 attached at its lower end to the lower pillar plate 5 which contains the pillar hinge 7. The length of the strut is adjustable by a screw device 19 and carries a spring acting on an eye 22 attached to a link 20 pivoted to the pillar plate 5. The pillar plate 24, Fig. 5, is made in two adjustably positioned parts as shown, and the forward end of the connecting-lever 30 has a stop 32 coacting with a stop 33 on the cant-rail 23. The upper part 25 of the plate 24 is also extended and provided with a lip 35 for attachment of the hoop stick. The link 28 and lever 30 are made of narrow construction to enable them to enter a central recess in the cant-rail.

Filed: 1939-11-24
Abstract: 533,980. Soot-blowers. WILSON, A. M. Nov. 24, 1939, No. 30698. [Class 99 (ii)] In soot-blowers of the type movable lengthwise into or from the operative position and provided with a valve which is actuated by this movement of the blower to control the flow of cleaning-fluid, a pressure-reducing valve is provided in interlocked relationship with the first-mentioned valve so that both valves open and close approximately in unison. Figure 1 shows a blower element 11, 12 movable lengthwise by a screw 17 engaging a nut 41, ports 11A in the tubular port 11 being brought into line with steam-inlet ports 15A when the blower is extended to its operative position. When this takes place, the nut 41 acts as a cam on a follower 38 connected by a bell crank 31, 32 to a pressure-reducing valve 26, Fig. 2, so as to open this against the pressure of a spring 24. The valve 26 may be permanently closed so as to isolate a particular blower, by screwing a nut 30 forming an abutment for the spring. In a modification, the pressure-reducing valve is fitted with a balancing-piston instead of a spring, and also with a pilot valve which is first opened to admit the steam pressure to the balancing-piston, the main reducing-valve being opened subsequently. The invention is applicable to the blowers described in Specifications 269,109, [Class 99 (ii)], 477, 833 and 516,009.

Toluene diisocyanate is the preferred organic polyisocyanate. A catalyst for the NCO-OH reaction may be employed in the formation of the adduct and in the reaction of the adduct with the alkyd resin. The modified alkyd resins may be converted to insoluble, infusible products by heating them in the presence of free radical catalysts and optionally reinforcing fillers such as cloth mats and fibres. In an example, toluene diisocyanate is reacted with allyl alcohol and the resulting adduct is reacted with an alkyd resin prepared from isophthalic acid, propylene glycol and fumaric acid.

Patent GB-900090-A (GB)
Title: Improvements in or relating to the refining of pig iron
IPC: C21C5/32
Filed: 1959-09-14
Abstract: A process for refining high phosphorus pig iron comprises blowing the pig iron in a basic Bessomer converter until the carbon end-point is reached, after-blowing to obtain a low phosphorus content, deslagging and transferring the melt to a second vessel, carburizing, and then refining the melt by blowing pure oxygen on to the surface of the metal after adding slag-forming materials.  The recarburization may be to a carbon content of 1-2% by means of coke or pig iron, in the latter case the phosphorus content may be raised to 0.8% at the most. The second vessel may be a ladle or a refractory-lined vessel having a solid bottom.

Abstract: 264,467. Renault, L. Jan. 18, 1926, [Convention date]. Shaft couplings; securing toothed wheels on shafts. - In resilient transmission couplings for power-driven road and rail vehicles, aircraft, &c., the stroke of the springs for a given angular displacement of the driving and driven members is increased by multiplying gear. A gear-wheel 16, Fig. 5, loosely mounted on the propeller shaft of an aeroplane and driven by an engine-shaft pinion (not shown) drives a member 18, fast on the propeller shaft, by axial levers 20 and springs 25. The end 24 of each lever engages between a pair of springs, the short arm being formed by a surface 21 eccentric to the pivot 19. The eccentric 21 has a spherical periphery to engage a complementary pair of shoes (not shown) which are received in a recess 23 in the wheel 16. The multiplication-ratio in this form may reach 30. Figs. 6 and 7 show means for obtaining still higher ratios. The springs 33 are compressed between lugs 34 on the driven member 18 and arms 32 integral with a loose pinion 31, which meshes with radial toothed sectors 27, pivoted on the member 18 and provided with eccentric hubs 28, engaging shoes lodged in recesses 30 in the driving-wheel 16. A fibre or like friction disc 35 may be interposed between the parts 31, 18, which are pressed together by a spring 36. In both forms, the normal driving-springs may be more flexible than those operative when the driven shaft drives. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a simple form in which the longer arms 10<1> of radial levers 10, Fig. 2 (Cancelled), pivoted at 9 on a drum 8 secured to the driven shaft, engage recesses 7<1> in the driving-shaft 7.

[Class 106 (ii).] In a device for carrying out elongation tests on a filament held between clamps, the movable clamp is carried by a rod which, after the operation of a releasing bolt, is retracted a predetermined distance by a spring, whereupon the latter is released simultaneously with the coupling of a return spring to the rod. The rod 6, slidable in roller bearings in frames 20, 25, carries at its left end spring jaws 35, 36, Fig. 3, integral with arms 12, the jaws normally holding a bolt 13 connected by a member 38 to a spring 15 anchored at 16 to plates 14. The latter carry spring hook members 10 normally engaging bolts 22 of a lever 23 slidable on the rod 6 and connected by springs 9 to fixed points 5. Operation. The thread 3 is held between clamps 2, 4, Fig. 1, the rod 6 being held by a bolt 19 engaging a slot in the rod. On release of this bolt the spring 15 pulls the rod 6 to the left until projections 29 on the frame member 30 engage the arms 12 and open the jaws 35, 36 to release the bolt 13. Simultaneously a wedge 8 carried by the rod 6 engages and opens the hook members 10 whereupon the springs 9 cause the lever 23 to return the rod 6 until the wedge 8 abuts against a stop 21. The elongation of the filament 3 is taken as proportional to the sag which is read off on a mirror and scale device 17. The travel of the rod 6 may be varied by the screw adjustment of the frame member 30 by means of a screw 32 rotated by a handle 33. The bolt 13 and lever 23 are returned to normal operative position by hand.
