Title: Prodn. of edible containers esp. for soft ice-cream - by baking, softening dough by moistening and seal-packing for use, heating, drying and moulding to required shape, and hardening by cooling
Inventor: ITO SADAHARU
IPC: A21D13/00
Filed: 1992-11-20
Abstract: The edible dough (2), made from ingredients e.g. principally meal, sugar, oil etc., kneaded and mixed with water, is placed between a hotplate (10) and a second hotplate, heated and baked so the starch in the dough is transformed and the moisture is vaporised, the obtd. baked pastry is moistened, and sealed in a waterproof packing, the pastry, which has been softened by absorbing the moisture inside the packing, is removed from the packing and is heated and dried and is moulded to the required shape and is hardened by cooling. The initial dough may be prepd. in a liq. form which is spread on the hotplate. The pastry is pref. moistened immediately after removal from the hotplate. The packing and sealing stage may be pref. replaced by a stage in which pastry units are stacked on each other with waterproof membranes sepg. them. The dough may be pref. formed to the required finished shape before baking. USE/ADVANTAGE - Used for mfg. edible containers, esp. for confectionery items, e.g. in partic. soft ice-cream. The container produced is porous and light and is crisp to the taste. It is packed to avoid contamination in transport, and is transported in a flexible form so breakages are minimised. It is reconstituted at the place of use with a very low energy consumption.

Patent DE-4300397-A1 (DE)
Inventor: HENDRY JAMES WATSON
IPC: B29C45/17
Filed: 1993-01-09
Abstract: A process and apparatus for injection molding and a plastic article having a hollow rib portion (72) is formed utilizing a spill cavity (73). The process includes the steps of sequentially injecting fluent plastic and gas into a mold cavity having a space defining at least one wall portion of the article and a channel (66) defining a rib portion (72) of the article. A quantity of fluent plastic is initially injected to substantially fill the mold cavity. A charge of pressurized gas is then injected into the channel (66) of the mold cavity to displace a portion of the still fluent plastic into the spill cavity (73) which is flow coupled to the channel (66). Preferably, the thickness of the rib portion (72) in cross section is at least twice as large as the thickness of the wall portion in cross section along the entire length of the rib portion (72). Also, preferably, the channel (66) is tapered along its length. The rib portion may be either internal or external to the article.

Title: Solids feeding into pressurised space - by pressurisable feed cell fitted with feed piston
Inventor: KILPELAEINEN REIJO
IPC: C10J3/30
Filed: 1993-03-01
Abstract: Solids are fed into a pressurised space through a feed cell (12), connected to the space by a closure device (13), and through an adjacent piston cylinder (8) using a piston consisting of an outer piston (11), which moves within the outer piston (10) and into the feed cell (12).

Title: Method and arrangement for producing grits and coarse meal products with energy-saving in tube mills, primarily in twin-chamber and triple-chamber tube mills with direct processing and separation of the products obtained
Inventor: SCHAEFER HORST
IPC: B02C17/06
Filed: 1993-06-29
Abstract: The traditional purpose of ball tube mills consists in producing stone dust with the fineness of cement. By applying the method developed and the arrangement and using the present mill capacities, stone grits of 40-80% with a grain size of 0.09-2.5 mm were obtained. The practical mill speed of <IMAGE>  was maintained. The grinding bodies used were small steel balls (not Cylpebs).

Title: Method for metering fuel in a cylinder-selective manner in spark-ignition engines
Inventor: HELD VEIT DR ING
IPC: F02D41/34
Filed: 1993-08-11
Abstract: The invention relates to a method for metering fuel in a cylinder-selective manner in spark-ignition engines in order to compensate different air/fuel ratios in the individual cylinders so that optimum exhaust gas values can be obtained at all operating points. For this purpose, an average firing time  PHI B of each cylinder is used as the basis, an arithmetic average value  PHI Bave being formed from the said average firing times ( PHI B) and in each case the sum of the average firing time of all the other cylinders being subtracted from the said arithmetic average value  PHI Bave. The result is separately integrated for each cylinder by means of a PI controller. The correction factor y which is acquired in this way multiplied by an average basic injection time supplied by the air flow rate meter supplies corrected injection times for each cylinder in accordance with the aimed-at air/fuel ratio. <IMAGE>

Title: Analytical method for electrode sensors
Inventor: KLEIN KARL-DITTMAR DR
IPC: C12Q1/00
Filed: 1993-09-06
Abstract: Interfering substances in a solution to be examined can falsify the measurement results of an electrode sensor in the case of an amperometric method. In the case of a potentiometric relaxation measurement method, this falsification of the measurement results can be avoided by operating two similar electrode sensors, only one of which is provided with an enzyme. The analyte concentration which it is desired to ascertain is determined from the difference between the measurement results of the two electrode sensors. The method is suitable for long-term monitoring or control of analyte concentrations in medicine or biotechnology.
