Abstract: The invention relates to the moulding of dough pieces, for instance in the production of bread. In a dough moulding machine, there are pairs of sheeting rollers, which roll out the piece of dough into a sheet. In the method of the present invention the dough piece is caused to pass over a fluidized bed in its approach to a pair of sheeting rollers. Further, the dough piece may pass over a fluidized bed as it is transferred from one pair of sheeting rollers to a following pair of sheeting rollers.The invention also includes an arrangement for replacing the usual feed hopper of a dough panner by a conveyor, a fluidized bed and lateral locating devices for the dough piece.

Abstract: Crude product substituted 1,3-diols obtained by aldolization and subsequent hydrogenation are treated at elevated temperatures with at least sufficient basic additives to reduce the saponification number to zero. Thereupon, the saponified product is reacted with 5 to 30% water and possibly cooled to 1.degree. to 30.degree. C. The aqueous phase is separated mechanically, and following the separation and addition of 5 to 30% water the organic phase is adjusted to a pH of 8.0 to 10.5. A second aqueous phase is removed and, thereupon, the monovalent alcohol is removed by distillation from the second organic phase. Again the pH value of the second organic phase is set at 8.0 to 10.5 and the 1,3-diol is recovered by fractionation.

Abstract: A getter device comprises a getter metal vapor releasing material and a source of an alkali metal which releases an alkali metal during or after the latter period of getter metal evaporation. Such getter devices are found to produce less methane after evaporation of the getter metal without producing higher hydrocarbons. A higher pressure of hydrogen is formed which aids cathode functioning.

Each panel comprises a frame formed of elongated channel members for strength and load bearing capability. The channel members are provided with spaced clip members which serve to support the insulation between the interior and exterior surfaces of the panel.

Abstract: An article of footwear comprising a flexible top portion of the upper, and a flexible under portion of the upper. The top portion and under portion are joined at their overlapped perimeters by handsewing or by machine stitching to form a forepart of the article of footwear and to form a seam therebetween. The seam is located closely adjacent and substantially parallel to the edge of a sole portion joined to the under portion of the forepart. In the case of handsewing, the perimeters of the top portion and the under portion are provided with apertures therethrough.

Abstract: A device for sealed attachment of substantially flat-surfaced cover strips, especially of sheet metal, for single- or double-curve roof surfaces of buildings, with top and bottom clamping members, which can be braced for the side attachment of adjacent cover strips by opposing bolts and which can be attached to a supporting frame. The clamping members have flat clamping surfaces to contact the substantially flat-surfaced cover strips and have clamping bolts that extend through openings on the lengthwise edge of at least one of any two adjacent cover strips. Cover rails are attached to the top clamping members and pass therethrough and are clamped by means of crosspieces which feather out to the side, which on their lengthwise edge carry sealing strips pressed against the outsides of adjacent cover strips.

Abstract: For the handling of portable large containers, lifting and depositing devices are used, which have rack and pinion jacks to be attached to the corners of the containers by brackets. There rack and pinion jacks have tubular winch shanks which are approximately the height of the containers, into which are guided tubular uprights with the racks. Because of tolerance variations, the danger here arises of an impaired guidance of the uprights with the result of a poor operation of the gearing. To avoid this difficulty, a guide tube is connected with the bottom end of each tubular winch shank. Guide surfaces in the guide tube can be produced with great precision and at low cost. The housing of the winch gearing is configured integral with the guide tube. Thus, a small amount of side play can be left between the upright and winch shank without adversely affecting the rack and pinion gearing operation.
