Abstract: The plant has an intermediate connection member (4) between a gas generator (3) and a power stage (7), which member (4) acts as a heat- exchanger for the stator box (6) of the power stage (7) with which lt is thermally in contact at its downstream end (4''). The member (4) is provided with an electric heating coil (15) embedded in its external surface and with an inner annular chamber (17) within which cooling air is caused to flow along a helical path from the downstream end to the upstream end of the chamber. Heating by coil (15) during start-up causes the stator box (6) to expand, thus permitting a reduction in clearance between the rotor discs and box (6). When elevated temperatures have been attained, the cooling air can cause appropriate cooling to ensure efficient operation. Valves 19, 22 can control the cooling air. <IMAGE>

Abstract: Along the roof ridge is a conventional copper wire fitted on distance holders. A second copper wire is positioned at right-angles to the first, running down the sides of the roof to the earthing point. A spike, pointed at its top, is vertically fitted and electrically connected to the copper wires. At the point where it is connected directly to the roof, the spike is located approx. 30 cms above the roof ridge, and is connected to the wires via bent connecting conduits. - These connecting conduits have four sides, and can be rigid wires or other completely copper bars welded to the spike. They are firmly welded whilst they are straight, and then are bent into position on the roof, their ends being clamped firmly against the wires so that a suitable mechanical stability is achieved.

Abstract: A procedure the life of wood-cutting tools and relates to the cutting of green wood and comparable organic materials. The dulling of tools in such cutting is mainly corrosion of the cutting edge of the tool, which could be almost completely prevented under laboratory conditions by applying a high-voltage direct current. The dulling is also limited in practice in the procedure, which is based on the realization of the specific resistance of wood which is sufficient to render unnecessary the electric insulation of the tool or the wood being cut from the frame of the cutting machine. Such an operation is difficult to carry out, but was formerly believed to be indispensable. The invention, the negative terminal of a DC source is connected with the grounded frame of the machine. The current is conducted from the positive terminal of the DC source, using a suitable anode brush, into green wood acting like an electrolyte at a point close to the tool that is to be protected. The wood-cutting tool, and on its side also the means for feeding and supporting the wood, will then act as cathodes in the system and they will be protected against wear caused by corrosion.

Abstract: A telephone circuit which may be monolithically integrated for generating control signals for displaying the telephone charges to a subscriber is coupled to an AC voltage signal generator of having a predetermined amplitude and frequency which are constant over time. The circuit includes a voltage generator for generating signals which are spaced over time and have a trapezoidal pulse waveshape. A multiplier circuit calculates the product of the signals supplied from the two voltage generators and supplies a signal which is sent to the speech circuit of the subscriber's line and is added to the speech signals. The trapezoidal pulse generator has a capacitor which is charged and discharged by a voltage to current converter of a non-linear type which is driven by exchange control components. The voltage across this capacitor forms the trapezoidal signals supplied by the generator. The converter supplies a current which is proportional to the voltage supplied to its input terminals for voltage values lying between two predetermined threshold values which are opposite in sign and have an identical absolute value. For voltage values beyond the threshold values, a constant current is supplied irrespective of input voltage variations.

Abstract: Bodies of revolution are produced having at least one peripheral groove whose width decreases towards the floor of the groove by rotating a blank 9 about its longitudinal axis while a pressure which exceeds the yield point of the material of the blank is locally applied. To avoid excessive hardening of the blank material during shaping, pressure on the blank is reduced from a maximum corresponding to the width of the groove at the peripheral surface of the blank, to the width of the floor of the groove, in accordance with the progressing depth of impression X1 to X5. The blank is rolled between ribs on a central roller (12, Figure 18) and ribs 7 and 8 on die segments 2 to 6. The initial portion of each rib is axially wide but radially shallow and the radial height of the ribs increase while their width decreases. <IMAGE>

Abstract: From the intermediary coupling jack between the telephone and the wall jack runs a cable, which is 5,10 or 20 metres in length, to a box with the domestic sound equipment. The loudspeaker cables are connected, together with the stereo, via the box. The equipment can include one or more loudspeaker cut-outs or dampers, but this usually requires one pair of cut-outs with load over the loudspeaker inputs so that the final stage of the amplifier is protected. The installation enables the line current to be monitored via the telephone line when the handset is raised for use in making a call and also when the telephone rings. With the current established the volume of acoustic equipment is regulated. @(Provisional basic advised week 91/02)@ @(4pp Dwg.No. 1/1)@.

The holding device 1 comprises a swivel arm 30 which at its one end is pivotably connected to a guide profile 2 and which at its other end has a fastening member 32 for the spare wheel 60. A rod 20 provided with a thread 21 is rotatably disposed inside the guide profile 2, which rod 20 at its one end has an eyelet 24 for connection of a crank 50. A nut element 25 is in threaded engagement with the said thread 21 and at least one link arm 33 is articulately connected to the nut element 25 and the swivel arm 30. The nut element 25 is arranged such that it is slidable relative to the guide profile 2, whereby the nut element 25, whenever the rod 20 is rotated by means of the crank 50, is displaceable along the guide profile and thereby influences the swivel motion of the swivel arm 30. The spare wheel 60 is hooked to the fastening member 32 whenever the swivel arm 30 is manoeuvred into a swivelled- down position, after which the swivel arm, through manoeuvring of the crank, is swung up such that the one side of the tyre of the spare wheel comes to bear against the holding device 1, whereby the spare wheel 60 is safely anchored and, at the same time, easily accessible and easily detachable in connection with, for example, a puncture. <IMAGE>
