Abstract:
A method of making confectioneries, particularly hard and soft caramel and jelly and gum products, by combining regulated quantities of the ingredients and mixing. During the mixing operation, steam is admitted into the mass of ingredients so as to directly heat the same for cooking of the ingredients. The mixing operation is carried out with rotary elements which rotate at speeds between 1500 and 3000 revolutions per minute.
Abstract:
A dough mixing and kneading machine wherein a horizontal drum has a sealable inlet opening at the top and a sealable outlet opening at the bottom. One end wall of the drum is pivotable to and from an open position and carries an L-shaped tool which sweeps along its inner side and along the internal surface of the cylindrical main section of the drum when the machine is in use. The tool is coaxial with the main section of the drum and is driven by a motor which is mounted at the outer side of the pivotable end wall. A second motor drives a shaft which extends into the drum below the axis of the main section and carries several angularly offset propellers which move the constituents of dough axially and radially of the main section.
Abstract:
A method of extruding a foamed thermoplastic plastics material wherein the plastics material and a pore regulating agent are fed into an extruder and are fused in a fusion zone. The pressure of the fused material is augmented in a further zone and the material is then caused to flow past or through an obstruction so as to be converted into the form of thin layers or strands. Thereafter, steam and a propellant are sequentially injected into the fused mixture in injection zones. The steam is either saturated or superheated and has a temperature not lower than that of the mixture. The pressure of the mixture upstream of the obstruction is higher than the vapor pressure of the steam downstream of the obstruction. The pressure of the fused mixture and steam, while the propellant is being injected, is greater than the condensation pressure of the steam. The mixture is then cooled and discharged in a still further zone whereupon it foams.
Abstract:
A kitchen appliance for the mincing or shredding of cooked pieces of beef for the preparation of corned beef includes an upwardly open bowl of substantially round cross-section and an upwardly protruded tool shaft which extends centrally thorough a bottom portion of the bowl and can be driven at high speed by a power source underneath the bowl bottom. On the tool shaft there is fixed a chopping tool having radially outwardly extending blades. The blades are arranged at different relative heights.
Abstract:
It is necessary to determine the effects of welding pressure in order to control the high-frequency welding process in the manufacture of pipes with longitudinal seams. It has been discovered that measurements of the height of the welding bead provide an approximation that is satisfactory for determining the mass of the bead, which is proportional to welding pressure in known pipe geometry. The height of the bead is transmitted by an optical system to the diode matrix of a commercially available diode-matrix camera. The results are processed to control welding pressure.
Abstract:
A system for non-destructive testing of metallic materials and for, in particular, welding seams. An ultrasonic sensor is employed and ultrasonic defect signals are producted according to the pulse echo method. The ultrasonic defect signals are digitized and the digitized signals are combined with signals corresponding to longitudinal positions along the welding seam. A defect curve is produced form the data resulting from combining the digitized signals with the signals corresponding to longitudinal positions along the welding seam. The resulting defect curve is compared with data from a catalog of classes of defects. The system eliminates the need for manual ultrasonic reinspection of presumed welding defects.
Abstract:
A stationary bowl of the apparatus has a bottom wall, and the upright drive shaft of a motor located beneath the bottom wall extends through the same and into the interior of the bowl. A tubular member surrounds the drive shaft out of contact with the same; the other open end of the tubular member is downwardly spaced from the upper end of the drive shaft and the lower end of the tubular member is welded to a tubular collar of a support ring located beneath the bottom wall and extending into the interior of the bowl through the bottom wall outside the tubular member. A second tubular member is placed from above over the shaft and the first tubular member, surrounding the first tubular member with clearance. Cooperating engaging portions at the upper end of the shaft and within the second tubular member engage one another so as to connect the second tubular member with the shaft for joint rotation. The lower end portion of the second tubular member is formed or provided with transversely projecting tool portions, such as comminuting or mixing blades.
