Title: Improvements in or relating to a method of heat hardening friction materials
Inventor: BATCHELOR CLYDE SOLOMON
IPC: F16D69/02
Filed: 1953-02-16
Abstract: Heat hardening friction materials of the type comprising asbestos, an uncured thermosetting binder, and an organic solvent for the binder are hardened by subjecting them to initial heat at an elevated temperature sufficiently high to effect rapid cure of the binder and above the boiling point of the solvent, in order to cause rapid evaporation of the solvent at a rate such as to cool the exterior surface of the friction material and prevent surface hardening before substantially all of the solvent has been removed and continuing heating until the friction material is cured to substantial infusibility.  The binder may be rubber and drying oil, or all drying oils, or oil modified phenolics.  The solvents may be mineral spirits, or varnish makers' naphtha.  In Examples a friction material of the asbestos binder type using a solvent having a distillation range terminating at about 300 DEG F. was cured in 5-6 hours by rapidly raising the temperature to about 300 DEG F. and then raising it slowly to 350-380 DEG F.  Heating may be effected in a furnace of the convection type, radiant heat furnaces, induction heat furnaces or by infra-red heating.

Filed: 1955-02-15
Abstract: <PICT:0799304/III/1> A hosepipe is lined with a plastic material such as natural or synthetic rubber or thermoplastic synthetic resin, e.g. a polyvinyl resin, by inserting a tube of the plastic material, inflating the tube to bring it into continuous contact with the inside of the hose, then heating the outside with one or more high-velocity streams or jets of a heated gaseous medium which is circulated in an enclosed endless path in course of which it is heated in order to bond the lining.  As shown, apparatus for performing the heating step consists of a plurality of nozzles 2 which may be annular (for treating one pipe) or rectangular and arranged in opposing pairs (for treating a number of pipes simultaneously) and a pump 6 and heater 7 to provide a circulating supply of hot air, mounted on a carriage arranged to run on rails so as to treat a continuous length (e.g. 100 feet) of pipe in one operation.  A similar apparatus without the heater may follow, to cool the pipe to a convenient temperature.  An external coating which may be of polyvinyl chloride may be sprayed on the outside of the hoses by annular nozzles each surrounding one hose adjacent to the inlet to the bonding unit.

Patent GB-290730-A (GB)
Title: Improvements relating to fluid pressure braking apparatus
IPC: G01F11/28
Filed: 1927-02-18
Abstract: 290,730. Tomlinson, A. V., (Compagnie des Freins Westinghouse). Feb. 18, 1927. Fluid-pressure; hand, foot, and personal actuation; force - transmitting mechanism. - Fluid-pressure brakes particularly for automobiles are applied in a number of stages initiated at definite positions of the control pedal and the mechanism for transmitting the braking effort during one stage is automatically coupled to the mechanism for transmitting the effort during a subsequent stage upon the initiation of this latter stage. In the apparatus shown the brake shoes are applied to the wheels by the pressure of the foot and the braking pressure is applied by fluid pressure. The foot pedal controls the valve 9 of the fluid pressure apparatus 10 by means of a floating lever 6 which is connected by a rod 13 to a lever 15 pivoted on a lever 18, mounted on a fixed pivot 19. The brakes are connected to the lever 15 by a link 29, lever 31 pivoted at 32 and a rod 34. The two arms of the lever 6 are so proportioned relative to the opposing resistance due to the spring of the valve 9 and the brake release spring that the lever 6 will rock in a counter-clockwise direction about its lower end on operation of the foot pedal and the lever 15 will rock about its pivot 17, bringing the brake blocks into contact with the brake drums also the lever 18 will be rocked to cause a projection 21 to abut against a stop 22. The increased resistance at this stage to further movement of rod 13 carries further depression of the pedal to effect rocking of the lever 6 to open the valve 9 and consequent operation of the fluidpressure cylinder 10 to move the piston rod 11 to the left. The piston rod is connected to a bellcrank lever 26 carrying a pawl 25 and pivoted on the lever 18, and this bell-crank lever is rocked to bring the pawl 25 into engagement with a tooth of a quadrant 16 on the end of the lever 15. The levers 15, and 18 are now mechanically coupled and rock about the pivot 19 on further movement of the piston rod 11 and the brakes are applied by both fluid pressure and foot operation. The control valve 9, which is of the type described in Specification 246,791, causes a reaction on the foot pedal to indicate the braking pressure effected. The connection 14 of the rod 13 to the lever 15 and the pivot 19 may be arranged to coincide with the axis of the rod 13 so that in the second stage of braking the movement of this rod is substantially zero. The fluid pressure application of the brake may be prevented until the foot application has been completed by a stop adapted to prevent movement of the control valve until a predetermined movement of the rigging has been effected. Alternatively on the completion of the brake application stage a valve may be opened automatically to effect the fluid pressure application.

Blocks g with distance gauge-pieces g<1> space the rails e from the staves, and the screws f may be countersunk or be provided with elongated but narrow heads f<2>. The corners of the gauge-lugs h<4> may be rounded off to facilitate the passing of the holders over the bars d, and the holders may be strengthened at their ends h<2>. The carrier-rails e may be channelled near each edge, and the inturned portions h<3> of the holder be bent back to fit into the channels; or the rail e may be of curved section as shown in Fig. 7.

Abstract: 1449761 Finishing fabrics E KUSTERS 31 Jan 1974 [7 Feb 1973] 4652/74 Heading D1S Apparatus for treating a fabric 3 having a heat-softenable pile 14 on one side thereof, comprises a tank 2 adapted to contain hot water; means for guiding the fabric 3 through a passage 4 from one side of the tank 2 to the other; means for guiding the fabric upwardly into the upper part of the tank 2, along a loopshaped path in the tank 2 and out of the tank over the part of the fabric entering the tank; and means 15 for removing water from and cooling the fabric 3, the arrangement being such that the pile 14 maintains an erect position after the fabric is withdrawn from the surface of the water. The fabric may be a carpet having a pile formed from loops or tufts of thermoplastic material, e.g. polyacrylonitrile. The treatment may be performed before the fabric is dyed. In one embodiment, Fig. 1, the fabric 3 is guided by rollers 5, 6, 7, after passing through the passage 4, into the tank 2 containing hot water, e.g. at 90-95‹C. A roller 9 guides the fabric along the loop-shaped path in the tank 2. The fabric passes out of the water at a shallow angle to the water surface 12. A suction nozzle 15 removes hot water adhering to the fabric and cools the fabric. Hot water removed by the nozzle 15 is returned to the tank 2. The inlet and outlet aperture 8 of the tank is relatively small to ensure that as little as possible of the steam atmosphere above the hot water is allowed to escape. In. another embodiment, Fig. 2, the roller 7 is replaced by two rollers 16, 17 with a beater roller 18 therebetween to give the pile a preliminary loosening. Two suction nozzles 15', 15 are provided on the pile side of the fabric, the nozzle 15' mainly removing hot water and the nozzle 15 mainly cooling the fabric.
