Title: Improvements in or relating to the braking of vehicles
IPC: B60T13/24
Filed: 1929-06-17
Abstract: 336,640. Dewandre, A., and Soc. Anon. du Servo Frein Dewandre. June 17, 1929. Fluid-pressure.-In a motor-vehicle braking system some only of the brakes, e.g. the front brakes a, a<1> are operated for all degrees of braking by the effort of a manually deflected lever or pedal b in combination with effort due to a vacuum or other servo mechanism f<1> controlled by said lever or pedal, as described in Specification 232,738, while the other brakes, e.g. the near brakes a<2>, a<3>, are simultaneously operated solely by power mechanism k fluid-coupled only to the servo mechanism f<1>. When the pedal b is depressed a valve h is opened and the power effort of the vacuum &c. cylinder f<1> is applied to the front wheel brakes only, through rods g, e, lever d, shaft c, levers d<1>, d<2> and rods e<1>, e<2>, manual effort being applied to the pedal to overcome reaction. A pipe l transmits the vacuum &c. through a. reducing valve o to the cylinder k having a piston m connected by a wire n, levers d<5>, d<6>, d<7>, shaft c<1> and rods n', n<2> to the rear wheel brakes. The regulatable reducing valve o enables the ratio of the braking efforts on the front and rear wheels to be altered according to the loading of the vehicle and comprises a casing o<1>, Fig. 2, having a valve o<3> held on its seat o<2> by a spring o<4> the tension of which is adjustable by a screw o<5>. The space below the valve is in communication with the induction pipe &c. or the vacuum cylinder f<1> by a pipe l<1> so that the tension of the spring o<4> determines the vacuum in the pipe l leading to the brake cylinder k for the rear wheels. For effecting release of the vacuum in the cylinder k a second valve o<10> is pressed by a light spring o<15> against a seat o<11> in an opening through the valve o<3>. The back of the valve o<10> is in communication with the pipe l so that when the vacuum below the valve o<3> is released the valve o<10> is opened maintaining equilibrium between the pressures in the cylinders k and f<1>. A hand lever p is provided for the rear wheel brakes, being connected by a rod p<2>, lost-motion device p<1> and arm d<9> with the shaft c<1>. Instead of using separate cylinders for the front and rear brakes a single cylinder with two opposed pistons may be used, the reducing valve o being arranged in a partition between the pistons. In a further modification, the vacuum cylinder k has a separate distributor valve connected by a Bowden wire with the valve h so that the valves are operated simultaneously or, if the cylinder k is in alignment with the cylinder f<1>, the valves may be connected by a rod. The reducing valve o may be replaced by mechanical means in the transmission for altering the ratio of braking forces. Pressure systems may be used instead of vacuum and the invention may be applied to hydraulic transmission systems.

Title: Resinous products
IPC: C08F20/62
Filed: 1958-06-11
Abstract: A heat-hardenable resinous material comprises an interpolymer of an acrylamide and at least two other ethylenically unsaturated monomers, one of which is an ethylenically unsaturated carboxylic acid, e.g. acrylic and metacrylic acids and monobutyl maleate, the interpolymer having amido hydrogen atoms replaced by the structure-ROR, wherein R is a saturated lower aliphatic hydrocarbon radical and R1 is hydrogen or a lower alkyl radical, the ethylenically unsaturated acid being used in an amount of from 8 to 30% of the interpolymer.  Acrylamides specified are acrylamide itself and methacrylamide.  Styrene is specified as a third copolymerizable monomer.  The resinous material may be obtained by condensing the acrylamide interpolymer with an aldehyde, e.g. formaldehyde, in the presence of an alkanol.  The resinous materials are useful in coating applications, for which purpose they may be compounded with other materials, e.g. melamine and epoxy resins.  In an Example (3) an acrylamide/methacrylic acid/styrene interpolymer is reacted with a butanol solution of formaldehyde and then formulated into a coating composition by admixture with toluene and an epoxy resin.  The Specification gives details of the preparation of the acylamide interpolymers with the aid of specified solvents, catalysts and modifiers.  Specification 826,652 also is referred to.

Title: Braking apparatus for wagons running upon railway tracks
IPC: B61K7/02
Filed: 1924-08-07
Abstract: 222,089. Deloison, F. P. M., and Deyon, J. D. B. Sept. 19, 1923, [Convention date]. Skid; electric and magnetic.-Means for braking wagons in railway sidings comprises a brake shoe. 2, having a steel bottom plate 1 slidable upon the rail 3 and a turnout guide 5, which is placed in position by means of a carriage 9 connected to an endless cable 13 wound on a winch 14 connected through reducing-gear 19 to a double wound electric motor 18 provided with an electromagnetic brake 20-22. The plate 1 is secured to a carriage 7, guided between the rail 3 or guide 5 and a guard rail 4, and fitted with rollers, 8, 8<1> whilst the carriage 9 is guided between bars 11, 12 and fitted with rollers 10, 10<1>. A motor controller 28 in the operator's cabin controls the operation cf the whole apparatus. In the inoperative position, the shoe is disposed on the guide 5, and when a wagon approaches, the operator closes the motor circuit 18<a> through an automatic contact 31, and one or other of the contacts 23-37, according to the speed of the wagon. At the same time the circuit of the electromagnet 22 is closed to release the brake 20, so that the motor drives the winch to move the carriage 9 to the right, Fig. 3. The carriage first closes a contact 59 in the motor circuit 18<b> and of an automatic contact 60, but the latter is not operated, as it is held open by the closed contact 31. The carriage then drives the shoe on to the rail 3, but when it meets the contact 23 - - 27 which is in the motor circuit 18a, it opens it, thereby opening both the motor circuit and the brake circuit. The contact 31 being thus released, the contact 60 closes the motor circuit 18b and the brake circuit, whereby the motor is reversed and the carriage is returned to the guide 5, whilst the shoe is left on the track. In its return movement the carriage opens the contact 59 to open the motor circuit and apply the brake. When the wagon reaches the shoe, the wheel mounts the plate 1 and carries the shoe with it until the guide 5 is reached, when the wagon proceeds on the rail 3 and the shoe moves along the guide. Provision is made for preventing a wagon from mounting the shoe when it is being placed in position by insulating the rail section A-B and providing a relay 78, which, when a wagon reaches the point A, attracts a circuit breaker 36 in the motor circuit 18<a>. The contact 31, if closed, then opens and allows the contact 60 to close whereby the carriage is returned to the guide 5 before the wagon reaches the shoe.
