IPC: C08L7/00
Filed: 1955-02-26
Abstract: Polystyrene compositions of improved impact strength containing up to 20 per cent of unvulcanized natural rubber are obtained by mixing solid divided polystyrene with unvulcanized natural rubber, blending by softening and working under heat and, if the rubber content is more than 20 per cent, adding further polystyrene. The rubber may be pale crepe, powdered spray-dried latex or reclaim. The mixture with polystyrene may be worked in a mill or internal mixer and granulated, or extruded and pelleted at about 140 DEG C.ALSO:Polystyrene compositions of improved impact strength containing up to 20 per cent of unvulcanized natural rubber are obtained by mixing solid divided polystyrene with unvulcanized natural rubber, blending by softening and working under heat, and, if the rubber content is more than 20 per cent, adding further polystyrene.

Title: A method of and an installation for treating cement raw slurry
IPC: C04B7/40
Filed: 1964-04-04
Abstract: Cement raw slurry is converted into raw meal suitable for burning in rotary kiln by mechanically reducing the water content of the slurry to form a cake, e.g. by means of a filter press, continuously feeding this cake to, and disintegrating it in, a stream of hot gas from the kiln to form particles, the majority of which are carried away in the gas stream, and subsequently separating the heated, dried particles from the gas stream and feeding them to the kiln. The particles not entrained by the gas may be either returned to the disintegrator or passed directly to the kiln. The disintegrator may be in the form of rotating rods or hammers. Figures (not shown) illustrate several flow schemes and disintegrators.

Title: Improvements in or relating to speed-limiting devices for rotors
IPC: G05D13/00
Filed: 1964-07-30
Abstract: The runner blades 71 of a hydraulic turbine are adjusted in a sense to maintain a constant speed by the moving cylinder 74 of a servomotor controlled by a governor-actuated piston valve 52. In the event of overspeeding a spring-loaded plunger 11 carried by a shaft 10 driven by the turbine moves outwardly under centrifugal force to move a bell-crank lever 14 out of engagement with a valve 15 which then opens to vent a chamber 17 and allow a valve 19 to open, this valve venting a chamber 21 to permit a spring 37 to move a piston valve 31 to the left. Such movement of the valve 31 isolates the governor valve 52 and makes pressure and exhaust connections with the servomotor such as to move the runner blades to maximum pitch.

Title: Sonic distillation process and apparatus
IPC: G01N25/14
Filed: 1968-09-13
Abstract: Water, or other liquid, to be distilled is passed through tubes 17 and 19 and through the tubes 25 of heat-exchanger 22 wherein the water is heated by heating-medium flowing through casing 23 the hot water then flows through pipe 30 into tank 10 where a body 33 of the hot water is subjected to sonic vibrations by piston 46 which is connected by elastic stem 45 to the housing of a vibrationgenerator 42 of the type wherein a roter 55 (Fig. 2) is driven, by pressurized air introduced through nozzle 57, in an orbit within a cylindrical bearing 54. The pressurized air is controlled to cause the rotor to follow its orbital path at a frequency corresponding to the resonant frequency of the liquid-loaded resonator. Vapour bubbles are rapidly evolved from the body of hot water, the vapour condenses on the outside surface of tube 17, and the condensate collects in tray 38. Residual brine flows out of tank 10 through pipe 34. Piston 46, which fits closely within annular wall 48, is supported on an inflated tube 52 of rubber-like material. The piston is faced at the top with a rubberlike material made of polyurethane or silicone. Heat-exchanger 22 is also equipped with a resonator 44a, of the type described, the piston 46a radiating sound waves upwards into the heating-liquid of the heat-exchanger. An orbital-mass generator 80 is mounted on condenser tube 17, whereby droplets of condensate are quickly thrown off, and drop into tray 38. The top 13 of tank 10 possesses elasticity and, when actuated by sonic wave generator 70, causes the downward movement of sound waves into the vapour space of the tank, thereby effecting condensation and agglomeration of minute particles of condensate. Orbitalmass oscillators driven by an electric-motor are referred to.

The feed worm is contained in a tube but projects therefrom at the lower end.
Patent ES-430963-A1 (ES)
Title: Rolled steel products and a method of making the same
IPC: B22D7/02
Filed: 1974-10-04
Abstract: A rolled steel product is made from molten steel and pieces of steel scrap of an analysis approaching that of the molten steel by feeding the scrap and molten steel into an ingot mold at the same time. Prior to feeding, the scrap is sized, cleaned and then placed in a cylinder arranged adjacent to and above the mold. The discharge end of the cylinder is closed with a gate and the scrap compressed by moving a plunger several inches to compress it in the cylinder. The scrap is then heated to remove the moisture, after which the gate is removed and the plunger moved forwardly at a steady rate to push the scrap into a chute leading to the mold. At the same time, molten steel is poured into the mold. The ingot is permitted to solidify and then heated in a soaking pit to rolling temperature after which it is rolled to semi-finished form, such as a slab, billet or bloom. The combination of heat and pressure in this operation welds or bonds the pieces of scrap to the surrounding metal and to each other, forming a unitary structure. The semi-finished form is then re-heated and rolled to the desired finished hot rolled product, such as sheet, strip, rod, bar or structural shape. This second heating and hot rolling operation with its combination of heat and pressure and very substantial reduction of area supplements and completes the pressure welding process initiated in rolling the ingot to semi-finished form. The steel is then ready for fabrication or use, or for further cold rolling or cold drawing in the same manner as standard hot rolled steel mill products. The end product is a plurality of small steel scrap particles interspersed in and bonded to a mass of steel.
