Abstract: In a device for suspending hanging scaffolds, consisting of an element (1) which can be suspended, for example, from the flange of a double-T-shaped girder (6) and possesses a passage and a bracket, and a clamping arm (11) which serves to fix the element (1) to the girder (6), engages with one of its ends behind the girder (6) and can be fixedly connected to the element (1), the clamping arm is rigid over its entire length. The device can thus not be used in the event that pipes or the like are laid on the girder. In order to eliminate this disadvantage, the clamping arm (11) is shorter than the width of the flange (5, 7) of a double-T-shaped girder (6) and a flexible connecting element (13) is fixed thereto by one of its ends, is passed through the passage in the element (1) by its other end, and can be fixed to the element (1) externally by its end projecting from the passage, by means of a bolt member (15) which can be supported on the said element (1). <IMAGE>

Abstract: A pulse control circuit for a d.c. series motor 10 having an armature 12 and two opposite-wound field windings, 14 F  and 14 R , comprises two semiconductor static switching devices, such as thyristors 22 F  and 22 R , each connected in series with the armature 12 and a respective one of the field windings 14 F , 14 R , control means 32 for varying the mark-to-space ratio of conduction of each switching device thereby to vary the mean voltage applied to the motor, one or other of the switching devices being brought into operation to energise the associated field winding in dependence on the desired direction of drive of the armature. The control means 32 is adapted, when the mark-to-space ratio of one of the static switching devices 22 F  or 22 R  has been brought to a predetermined maximum valve, to cause simultaneous operation of the other static switching device 22 R  or 22 F  at a lower mark-to-space ratio thereby to energise the associated field winding 14R or 14 F  so as to reduce the net flux in the motor 10 and further increase the motor speed.

Abstract: A process for the preparation of urea at elevated temperatures and pressures in which ammonium carbamate is decomposed into ammonia and carbon dioxide and separated from the urea product stream in at least two pressure stages. The product urea stream having reduced ammonium carbamate content leaving the first high pressure stage is reduced in pressure to a level intermediate the pressure of the high pressure stage and the next pressure stage in a pressure reducing device in which the energy released by the pressure reduction is converted into kinetic energy by means of which a gaseous mixture of ammonia and carbon dioxide resulting from the carbamate decomposition in a further pressure stage or recovered the process condensate formed in a concentrating stage is compressed to the intermediate pressure. The resulting compressed mixture is thereafter condensed, and the condensate thus formed is pumped to the high pressure stage.

Abstract: A multilayer, heat shrinkable composite tube covering 120 is provided for a cable joint structure in which intimately joined layers define a semiconductive inner conductor shield 112, an insulation layer 114, and an outer insulation shield 116. Furthermore, a highly resistive semiconducting layer 111 is provided over the joint under the innermost layer 112 of the composite tube, forming a dual layer conductor shield for the joint. In the preferred embodiment, the entire composite tube is pressure extruded in a common operation and all three layers are simultaneously chemically cured and cooled, under pressure to provide the intimately joined layers of the composite tube. Subsequently, when the tube is shrunk over the joint the three layers shrink as a unit, so that there is no possibility of trapping impurities or gas bubbles between layers.
