Title: Equipo sedimentador
Inventor: MONTERDE RICARDO JORGE
IPC: B01D21/24
Filed: 1997-12-12
Abstract: La presente invención pertenece a los equipos para la separación por sedimentación de partículas en suspensión y dentro de éstos a los equipos de decantación de un sólo compartimiento con múltiples salidas, llevando raspadores rotatorios los cuales son utilizados en el área de purificación de jugos de la Industria Azucarera y que pertenecen a la Clasificación Internacional de Patentes B01D 21/24. El objetivo fundamental de esta invención es trabajar con bajos volúmenes de jugo en proceso lo cual disminuye las pérdidas por inversión de sacarosa debido al bajo tiempo de retención del jugo y de la cachaza y con ello lograr una alta eficiencia, además obtener un equipo sencillo con notable ahorro de materiales para su construcción, mantenimiento y limpieza, y gran simplificación de la operación. Así como utilizar parámetros de diseno que eliminen la turbulencia y garanticen una rápida recuperación ante cualquier problema operacional. La presente invención tiene como novedoso un sistema de alimentación de jugo (fig. 2) formado por un conducto de forma cilíndrica (Fig. 1) que desciende desde la parte superior del techo y se introduce dentro de la masa de jugo, este conducto termina en una campana circular inclinada y dividida en secciones que garantiza la baja velocidad de salida del jugo y que la alimentación se realice en forma radial hacia la periferia. El sistema de extracción de jugo clarificado (Fig. 3) se realiza por ranura en la parte superior del tanque y una canal concéntrica del sistema de alimentación que descarga el jugo a una canal externa y de ahí directamente al proceso sin el uso de cajas de corrida; y una canal receptora de jugo mezclado ubicado en la parte superior externa del equipo y que alimenta el jugo al interior del mismo a través de un castillo (Fig. 4) y un espesador de cachaza en el fondo del equipo.

Patent DE-2003299-A1 (DE)
Title: Dough/waffle fryer
Inventor: ARNDT WOLF-DIETRICH DR
IPC: A23L5/10
Filed: 1970-01-26
Abstract: Dough strand is extruded into a bath of oil for frying, with the pressure at the entry higher than the water vapour pressure in the dough. Temp. and pressure in the bath, together with dough feed rate may be adjusted so that the dough reaches optimum structure at a point in the bath where the pressure in the bath equates with the water vapour pressure in the dough. Specif. the dough passes along to begin with and is stiffened prior to the onset of expansion and evaporation due to the raised temp of the bath at this pressure point. The dough is extruded into the bottom part of the bath or tube and rises under gravity or by friction caused by the fast flowing oil in the bath. Surface and texture of the dough can be adjusted by temp and pressure and flow controls, thus rendering the layout universal in application and capable of handling strand or piece doughs.
Patent DE-2007299-A1 (DE)
Title: Turning completed stockings for finishing
IPC: D04B15/92
Filed: 1970-02-18
Abstract: As the stocking develops from the needle cylinder of the circular knitter, it is supported by a double flange plate and/or clamps while it is progressively inverted into a suction tube located below the needle cylinder. As the stocking is draped in two folds, and supported, only half the normal length of stocking is held in the suction tube and the pulling effect will not cause fabric damage through the tension on the material at the needles. The design also eliminates the intermediary stocking turning stage normally located between stocking release from the knitter and ejection from the transport system.

Patent DE-2024064-A1 (DE)
Title: Drop forging of sintered iron alloy for high density
IPC: C22C33/02
Filed: 1970-05-16
Abstract: High density iron alloys are produced by a process comprising (a) moulding a powder mixture comprising Fe and at least one reinforcing element, selected from C, Cu, Ni, Cr, Mn, Mo and W; (b) presintering the shaped body at a temp. between 600 and 1200 degrees C at which the reinforcing component does not yet diffuse into iron and the reinforcement produced during the pre-forming is annuled; (e) rapidly heating the material for a short time to substantially prevent diffusion of the reinforcing element(s) into iron; and (d) hot-pressing the body under a pressure of 4-7 T./cm2. By this method, the resistance of the body to plastic deformation is lowered and a product of a very high density (e.g. 99.5% theor.) is obtained.

Title: Foamed sweetmeat prodn plant - esp for aerated chocolate with travelling low-pressure hood
Inventor: GILIARD JULIUS DIPL-ING
IPC: B29C44/34
Filed: 1971-07-05
Abstract: The chocolate is poured into moulds on a conveyor and passed into a low-pressure conditioning zone as in the parent patent. The low pressure zone consists of a vacuum - hood with a flexible sealing skirt which is suspended from two vertical linear actuators themselves hung on a travelling horizontal carriage with lead screw etc. drive which is lowered onto the belt as each new batch of filled moulds enters a starting position and then travels along with the belt for a predetermined time and distance, after which it is lifted and returned to the starting position whilst the conveyor feeds a fresh batch into position and takes the batch which has been foamed to e.g. the packing station. The belt is esp. of thermoplastic material and the moulds for the chocolate are themselves moulded integral with it. It is driven by sprockets and rows of sprocket holes along each edge as with a cinematograph film. The package is completed by a sheet of similar thermoplastic material laid over the belt after the last operation has been performed on the chocolate and welded around the peripheries of the moulds which are then cut from the combined belt. Relatively simple plant avoiding friction losses associated with pulling belt through air-lock doors.
