Abstract: 1. Supporting and carrying handle for visual display units. 2.1 The supporting and carrying handle (1) for visual display units is intended to enable the inclination of the display plane to the horizontal to be capable of adjustment corresponding to the user's requirements, at a low cost, and, in addition, to enable the visual display unit to be transported conveniently. 2.2 The supporting and carrying handle (1) is fitted on the rear side of the visual display unit (2) and is supported on one side on an axle (3) which can move horizontally. A rotatable locking lever (4) is provided which is fitted with inclined planes in the same way as the movable axle (3), so that, when the locking lever is rotated, a latching tab, arranged on the axle, is moved out of one of a plurality of notches (7) located in the supporting and carrying handle. The supporting and carrying handle is in this case released so that it can be moved to another latched position. One of the latched positions, which can be reached by a rotation through approximately 180 DEG , results in the supporting and carrying handle (1') being in such a position that it can be used as a convenient carrying handle. Visual display units and other display units of all types. <IMAGE>

Abstract: A method of producing frozen dough for baking or frying to form bread comprises stretching the dough on a series of conveyors (1,2,3) while subjecting it to vibrations by means of rollers (5) so that the dough can be stretched without imparting pressure exceeding the yield point of its elasticity. Thus the gluten network structure is unharmed. Then the dough is frozen for preserving, and after a desired period of preservation the dough may be baked. By avoiding damage to the gluten network structure, the dough deflates less than conventionally treated dough during freezing and expands mo during the baking step, so that puffy and tasty bread results.

Abstract: A burner with an integrated electrical high-voltage igniter and a flame monitor for partly oxidizing gaseous fuels in reactors that are either pressurized or not. A fuel-gas channel communicates with a confusor which opens into an annual fuel-gas nozzle. The fuel-gas channel, furthermore, is surrounded by an annular oxygen channel. Water channels border the confusor and the annular fuel-gas nozzle. The annular fuel-gas nozzle, moreover, has the confusor, and annular nozzle with a reaction zone end, and a diffusor. This diffusor merges into the oxygen channel at an axially parallel radius of curvature. A high-voltage ignition cable extends through the fuel-gas channel and terminates in a metal electrode which is positioned so as to form a spark gap in a space between the tip of the electrode and a metal wall of the burner. In this space within the spark gap, the fuel gas and oxygen mixture is turbulent, whereby the fuel-gas channel provides a reliable and certain ignition of the fuel gas and oxygen mixture independent of gas pressure in that space. The radius of curvature is located at an exit end of the diffusor and extends into the oxygen channel for separation of gas from walls of the diffusor to produce a vacuum in the spark gap space for suctioning the oxygen from the oxygen channel.

Abstract: A foot and ankle supporting and orienting extension for an external fixation unit with pins driven into the tibia of a patient has a coupling member which can be separably connected to a pin holder of a fixation unit, a variable-length carrier one end of which is articulately connected to the coupling member by a first universal joint and the other end of which is articulately connected to one end of a variabele-length link by a second universal joint, and a cushioned sole-contacting brace which is articulately connected to the other end of the link by a third universal spherical joint. By properly selecting the mutual inclination of the coupling member, carrier, link and brace relative to each other and/or by properly selecting the length of the carrier and/or the link, the patient or another authorized person can move the cushion of the brace to an optimum position relative to the sole of a foot forming part of a leg wherein the tibia is pinned to a fixation unit. This ensures that the foot and the ankle can rest in an optimum orientation. The joints can be locked to prevent articulation of the carrier, coupling member, link and brace relative to each other as soon as the cushion of the brace assumes an optimum position relative to the sole.
