Title: Method for the preparation of paving compositions and composi tions obtained by such method
IPC: C08L95/00
Filed: 1972-06-15
Abstract: 1354855 Bituminous composition COMPAGNIE FRANCAISE DE RAFFINAGE 15 June 1972 [15 June 1971] 28135/72 Addition to 1332825 Heading C3N A method for the preparation of paving compositions comprises mixing at 160-210‹ C. an aggregate of particle size greater than 80Á, a hydrocarbon binder, a filler of particle size less than 80Á and hard asphalts, the aggregate, filler and the binder having been preheated and the hard asphalts being in the form of a non- preheated powder the size of which does not exceed the size of the finest part of the aggregate. The term "hard asphalts" is defined as substances containing at least 40% by weight of hard asphaltenes (insoluble matter in n-heptane) and having a carboid content of less than 30% by weight. Preferably the hard asphalts contain no more than 25% by weight of products soluble in n-heptane. The softening point of the hard asphalts may be 120-200‹ C. Natural asphalts may also be used as hard asphalts after being ground to a powder of the required particle size. The hard asphalts preferably have a particle size not above 20Á. The hydrocarbon binder is derived from coal or oil and may be bitumen. The filler may be sand, limestone, slag, lime, vulcanized rubber or coke whilst the aggregate may be a mixture of sand and gravel.

Abstract: 149,158. Keesey, E. W. Nov. 14, 1919. Plane - trigonometry calculators.-Relates to apparatus for graphically solving problems involving wind and air speed and ground speed of aircraft. A base a with bearing and compass graduations has pivoted at its centre an arm b having an extension b<1> with speed graduations for wind. A slide f on the extension has pivoted to it an air-speed arm c and a transparent disk e with bearing graduations. On the base a are inscribed a set of parallel north and south lines with which are adapted to be set corresponding parallel north and south lines on the transparent disk e. An aperture with index mark c<1> is formed on the arm c. A third arm d is pivoted at the centre of the base and carries a slide in twc parts pivoted together, the second part h<2> of which similarly engages the arm c. Reading edges on the two parts indicate against scales on the arms c and d the air and ground speeds respectively. A second scale may be inscribed on the arm d to read the time required to cover a given distance such as ten miles. The arm d is mounted on a boss on the arm t between it and the extension b<1> and the whole assembled by a stud o<1>, Fig. 2, with securing screw o<2>. The boss on the arm b<1> is slotted to engage lugs on the arm b. The slide f is offset from the centre of the transparent disk so as to allow the latter to be set to the centre of the base.

Abstract: 298,563. Waygood-Otis, Ltd., (Assignees of Lautrup, G. W.). Oct. 11, 1927, [Convention date]. Electric; applied by springs; blocks acting on drums.-Brake mechanism, particularly multiple shoe braking mechanism for elevator hoisting machines mechanically applied and electrically released, comprises a pair of operating members actuated for moving the brake shoes by the rotative element of a motor the frame of which is pivotally supported by the operating members. The operating members 15, 16, carrying pivoted shoes 21, are pivoted on a fixed frame 11 at 17, 18 and carry the frame 55 of the motor by means of levers 57, 62 which are pivoted to the frame at 56, 61. A pinion 68 on the motor shaft meshes with a rack 67 on a lever 65 integral with the lever 57, and on energization of the motor these levers act about the shaft 56 as fulcrum to move the member 15, and consequently the member 16, away from the drum, against the action of the brake applying springs 42 enclosed in recesses 41 in the members 15, 16 and bearing against adjustable stops 51 on a rod 44. The piston rod 74 of a dash pot is pivoted to the end of the longer arm of the lever 57 and the cylinder 70 is pivoted to the end of the lever 62. It is provided with a ball check valve 77 and an orifice adjustable by means of a longitudinally slotted screw 81. The piston is adjustably threaded on the rod 74. The rack 67 may be adjusted relative to the pinion 68, with the brake applied, by means of a rod 83 pivoted to the motor casing and carrying adjustable collars 87 on each side of the lever 62 through a slot in which the rod passes. Adjustment of the collars 87 moves the motor casing relative to the pivot 63 which connects the member 15 and the lever 62 and rotates the shaft 56. Brake shoe adjusting and positioning screws 24, 27 are provided the latter having a spring 32 arranged between lugs on the end of the screw and on the shoe. Spring-pressed stop-pins 40 are provided in recesses in the lower portions of the members 15, 16 and bear against the frame 11 and may be adjusted by nuts 38 in order to adjust the clearances between the brake shoes and the drum.

Abstract: 1,067,228. Transporting moulded blocks. SCHLOSSER & CO. G.m.b.H. July 9, 1964 [July 11, 1963], No. 28272/64. Heading B5A. Take-off gear, for transporting concrete blocks away from a moulding station, includes means whereby the blocks may be selectively directed towards either an air hardening station or a steam hardening station. In the embodiment shown in Fig. 1, blocks moulded at 1 are transferred by a feeder 1<SP>1</SP>, lifting gear 2, and a transversely movable platform 3, to one of two steam hardening chambers 10. The hardened blocks are removed from said chambers back on to platform 3 and are transferred by lowering gear 5 from the platform on to a conveyer 7, whence they are placed in air storage chambers 9. If air hardening is required the blocks are transported directly to chambers 9 along a link 6 in conveyer 7, which link is slid transversely into position for air hardening and is retracted for steam hardening. In a second embodiment (see Fig. 2, not shown) the slabs are first conveyed to a steam chamber located at one side of the moulding station and then to a first storage chamber located at the other side of the moulding station by a pneumatic fork lifter. A removable link (6<SP>1</SP>) is again included in conveyer 7 so that the blocks may be fed directly to second chamber 9 for air hardening. In a third embodiment (Figs. 3 and 4, not shown) the blocks are conveyed to steam chambers either side of the moulding station by an overhead crane system, the conveyer 7 being connected directly to feeder 1<SP>1</SP>, without a link, so that the air drying chambers 9 9 may be used by merely rendering the crane system inoperative and the conveyer operative.

Machine drive. The apparatus is driven by a motor 500, Fig. 5, connected to two coaxial pulleys 502 and 503. Pulley 503 drives the orientating wheels 51<SP>1</SP> through a shaft 41<SP>1</SP>. Pulley 502 drives belt 504 around pulleys 505, 178<SP>1</SP> and 506, pulley 178<SP>1</SP> driving the peeling turret. Pulley 505 has gears 510 driving wheel 511 having gears 512 meshing with gears 513 on shaft 514 driving a feedstar 42<SP>1</SP>. Gears 513 also mesh with gears 109<SP>1</SP> which drives table 47<SP>1</SP>, and gears 109<SP>1</SP> via idler gears 166<SP>1</SP>, with gears 167<SP>1</SP> secured to the shaft of the peeling turret. Pulley 505 has a coaxial pulley which drives a pulley 516 having a coaxial pulley 199<SP>1</SP> which drives pulleys 565<SP>1</SP> and hence the fruit support spindles 194<SP>1</SP>. The coring mechanism 206<SP>1</SP>, Fig.14, and lower indent pick-up finger 152<SP>1</SP> have a separate support and actuating mechanism to allow greater flexibility in positioning. The locations of cams and levers are changed so that changes in the timing relationships between the controlling mechanisms are possible. Cam ring (573), Fig.12 (not shown), has a pair of slots (630, 631) in which bolts (632) are slidable, so that the vertical position of the upper indent finger can be adjusted or the plate angularly turned to change the timing of the operations. The actual operation of lifting the apple is altered so that the lower finger 152<SP>1</SP> engages the apple at a position in front of the upper finger 153<SP>1</SP>, is then relatively decelerated with respect to the upper finger 153<SP>1</SP> which moves ahead of the lower finger 152<SP>1</SP>, which is then accelerated back to a coincident position. This movement of the lower finger 152<SP>1</SP> produces a more vertical rise of the lower finger 152<SP>1</SP> to the fruit carrying receptacle 46<SP>1</SP>. (for figures see next page)
