Patent SE-7710559-L (SE)
Inventor: WEBB R P
IPC: H04B10/29
Filed: 1977-09-20
Abstract: A signal level stabilizer includes two amplifier stages, each stage having a respective feed-back loop to control its gain. The gains of the amplifiers are varied in response to variations in the level of the input signal to give a substantially constant output signal. At low levels of the input signal the gain of one of the amplifiers only is varied in response to variations of the input signal and at high levels of the input signal the gain of the other amplifier is varied. The amplifiers may be part of a repeater in an optical communications linkage and one of the amplifiers may then be a photodiode and the other a power amplifier.

Abstract: A large antifriction bearing composed of a plurality of segments for absorbing forces generating axial, radial and pitching forces, in which each of the individual segments is formed by two bearing ring segments. Within the region of the roller path of the large antifriction bearing one bearing ring segment has a cross section of a substantially one-piece T-shaped profile, whereas the other bearing ring segment in cross section is designed as a U-shaped profile partially surrounding the flange of the T-shaped profile. Holding ring segments are detachably connected to the the ends of the two free legs of the U-shaped profile and extend into the region of the web of the T-shaped profile. The bearing ring segments which abut each other and form the large antifriction bearing are guided by runningpath wires inserted into the bearing ring segment and bridging the areas abutting each other.

Abstract: A transducer for converting the energy of ocean currents to the energy of a high-pressure fluid comprises a plurality of transducer units each including a sea-water channel, a plenum room overlying the channel, an impeller rotatably disposed in the channel and plenum room and rotatable by a sea-water flow through the channel, and a converter mechanism operatively coupled with the shaft of the impeller for producing a high-pressure fluid in response to revolution of the impeller. To prevent pressurized air in the plenum room for leaking out of the transducer unit when the transducer is joggled underwater as in stormy conditions, a pair of air-trapping chambers are located one on each side of the plenum room and open toward the channel for receiving any air which has escaped from the plenum room through the channel. Each chamber may contain a part-spherical air-trapping member that is pivotally movable into the channel upon inclination of the transducer so as to prevent the trapped air from leaking out of the air-trapping chamber.

Abstract: The re-emitted light or the amount of light, reduced after absorption, of a test object (3) and a reference object (2) which are exposed to a single light source (1) is passed to one optical sensor (10, 11, 12) each with the aid of light guides (4, 5, 6). Arranged in the beam path to the optical sensors there are replaceable optical filters (7, 8, 9) having a narrow pass bandwidth. An analysis unit transforms the signals of the reference object (2) and the test object (3) for various working wavelengths by mathematical transforms, standardises these and converts them into a single variable which can be used for a highly significant Good/Bad decision. The analysis unit with its test program is used both to determine the most advantageous filters (7, 8, 9) and, after these have been defined, for distinguishing test objects. <IMAGE>

Abstract: A brake for bending sheet metal comprising a pair of spaced base rails and a plurality of C-shaped members positioned on the base rails at longitudinally spaced points. Each C-shaped member comprises a lower arm fixed to the rails and an upper arm spaced from and overlying the lower arm. A first member is fixed on the lower arms of the C-shaped members and has a clamping surface. An anvil member is adapted to be locked on the first member to clamp a piece of sheet metal between the anvil member and the clamping surface of the first member. A second member having a bending surface is pivoted to the first member. The anvil member is generally L-shaped with a horizontal portion and a vertical portion. The vertical portion has longitudinally spaced notches therein through which the upper arm of each C-shaped member extends. The anvil member is resiliently mounted on the upper arms. An abutting portion is provided on the upper arm of each C-shaped member and is adapted to be contacted by the vertical portion of the anvil member and thereby minimize any tendency for rotation of the anvil member when the second bending member is swung to bend a piece of sheet metal or the like clamped between the anvil member and the clamping surface of the first member.

Abstract: Root crop cooker, in particular for cooking beetroots, with a cooking chamber (11) which has at the bottom a water bath (19) with heating means for steam production. Two circumferential support belts (14, 16), one (14) above the other (16), are arranged in the cooking chamber (11) and movable independently of one another. On the upper support belt (14), root crops to be cooked are arranged in a layer (29), through which steam is pressed. A part of this steam condenses on the root crops which are thus heated to a given temperature. After a given time, the root crops are transferred over onto the second support belt (16), on which they are arranged in a considerably thicker layer (30) than on the first support belt. The root crops on the second support belt (16) are finish-cooked without steam being supplied and moreover, as a result of their position under the first support belt (14), serve as a filter layer which collects impurities in the condensate which drips down from the first layer (29). The cooker consumes a very small quantity of water and furthermore requires extremely little energy. The cooked root crops also have considerably better quality. <IMAGE>

Abstract: The process is for controlling combustion in which fuel and air are fed to a burner (2) in a boiler (1). The temperature of the combustion gases in the boiler (1) is measured, and dependent upon this measurement the combustion air flow is regulated relatively to the fuel flow. This ensures maximum combustion efficiency, and thereby maximum temperature in the combustion gases. - In the boiler (1) is a burner (2), a fuel supply conduit (3) with a regulator (5), and an air supply line (4), also with a regulator (6). The boiler also has a transmitter (7) and a control (10) which, dependent upon the signals from the transmitter (7) regulates the flow ratio between fuel and air. The transmitter (7) comprises a temperature indicator, and the control (10) can regulate the combustion air feed control (6) so that the boiler combustion gases are maintained at the maximum temperature level.
