Title: Extruding thin-walled edible dough prods. by dies - holding parallel strong plastic mono:filaments anchored above die entry
Inventor: MAROUDAS JOHANN
IPC: A21C11/16
Filed: 1989-04-12
Abstract: Dough is formed into continuous strands by extrusion through multiple apertures in a known extrusion head.  To ensure that at least part of the length of each strand has apertures inside very thin side-walls, into each extrusion aperture extends either a single wire or bunch of wires formed of high-strength plastic monofil (7). The monofil ends are integral with a block (8) and may be of different lengths. The resultant bores formed in extruded strands provide capillary access to the strand interiors, ensuring quick cooking by boiling water; micro-wave ovens may be used. Individual monofils may be profiled, e.g. with star shaped or T-cross sections. The holder block may be a ring. USE/ADVANTAGE - Esp. for quickly cooked materials such as macaroni. Though strands are largely hollow, strength is adequate.

Patent DE-4020253-A1 (DE)
Title: Assessing characteristics of deformable mass
Inventor: VALA JAN
IPC: B28C7/02
Filed: 1990-06-26
Abstract: The method is for assessing the characteristics of a plastically deformable substance which is capable of being poured, such as concrete. A sample of the substance is produced with the water or other liquefier content being increased step by step whilst the force required to operate the mixing machine is measured at each such step. A graph (1) is plotted of these results with the amount of water or liquefier being measured along the X-axis and the force required to drive the mixing machine being measured along the X-axis. The graph can then be used to define the ratio of the water or liquefying agent to the other ingredients.

Title: Removal of hazardous substances from hot exhaust gas - using temp. reduction pre-absorber followed by spray columns
Inventor: HEINZE WILFRIED DIPL ING
IPC: B01D53/68
Filed: 1990-11-27
Abstract: To clean hot exhaust gases of hazardous components, such as from Al foundries, they are passed to a temp. reduction preabsorber. Within the absorber, jets deliver a fine spray at an angle of 90 deg. to the axial direction of the gas flow with a water based washing medium together with additives with a high affinity to the unwanted substances in the gas. Pref. one or more spray absorption columns are behind the temp. reduction preabsorber, with the same jet assembly and working direction. At the preabsorber and the spray absorber columns, the jets are at an angle above buffer stores to take the gravity flow of soiled washing medium. The cleaned gas leaves the system with an absorption deg. of 99.5%. The washing medium, pref. whitewash, has pH of 11 and is recirculated from the buffer stores until it reaches a pH of 4. Through the acid change of the washing medium, into the acid zone, the spray jets are given a self-cleaning action. The soiled washing medium, close to its effective limit, is passed to neutralisation vessels with H2SO4 and mixed hot ashes. It is separated into a fluid and solid phase in a filter trough, for the fluid phase to be returned to the washing medium circuit. Whitewash is pumped into mobile intermediate stores so that fresh whitewash is immediately available at the preabsorber and the spray columns when the washing medium is renewed. ADVANTAGE - The technique is highly effective in clearing the gas of unwanted solid, fluid and gaseous components at a low cost, with reduced energy and washing medium consumption.
