Abstract: A cutter bit hard tip (62) has an outer tip section (76), an inner flange section (78) , and a middle section (80) disposed between and merging at its opposite ends with the tip and flange sections and being defined by a continuous concave surface of revolution (82). The tip, flange and middle sections lie along a common longitudinal central axis (84). The tip section has a rounded-off end, and a frusto-conical surface of revolution (88) merging from the end. The flange section has a right cylindrical surface whose diameter is greater than the maximum diameter of the tip section. The middle section has a maximum diameter less than or equal to the diameter of the flange section and a minimum diameter substantially equal to the maximum diameter of the tip section. The concave surface of revolution of the middle section in profile has an outwardly and downwardly sloping configuration generally similar to that of the sides of a bell-shaped curve.

Abstract: The arrangement includes pref. three hydraulic jacks (4) under the nose and wings of the aircraft. The jacks are connected to a control unit (5) with a switch for selective manual or automatic operation in conjunction with an attitude sensor (3) attached to the underside of the fuselage. In manual operation each individual jack (4) can be raised or lowered e.g. by a joystick. In practice the three jacks are first positioned manually under the jacking points and adjusted for level with a pendulum and target device.

IPC: E05F1/10
Filed: 1988-05-11
Abstract: A skylight, having a wing actuated by pneumatic springs, can be moved to an emergency opening position thereby substantially exposing the opening area of the skylight case. The skylight also acts as a residential ceiling or attic skylight which has, in the normal open position, a considerably smaller opening than in the emergency open position. A locking device is provided to restrict the long extension stroke of the piston rod of the pneumatic springs to a partial stroke. This partial stroke allows an opening which essentially corresponds to the standard opening of the wing in a residential skylight. The locking device, located on the cylinder of the pneumatic spring, includes a specially designed latch which, in order to effect partial stroke restriction of the piston rod, lockingly engages a stop located on the side of the case by means of a catch pin.

Abstract: An antilock brake device for vehicles including a sensor (21) for sensing the possibility of wheel lock during braking by means of overrunning rotation of a flywheel (72) interlocked with the wheel (2f) to produce an output and a hydraulic controlller (7) for reducing the braking hydraulic pressure of the wheel brake (3f) upon reception of the output from the sensor (21) and increasing the braking hydraulic pressure when the output from the sensor is eliminated. The flywheel and a transmission (45) for transmitting the rotation of the wheel to the flywheel are arranged in the hollow portion (8a) of a hub (8) of the wheel. Transmission mechanisms are employed to separate components within the hub to further reduce the overall size of the system.

Abstract: A system (11) for indicating the level of material (28) in a vessel (22) as a function of material capacitance comprising a resonant circuit (14) including a capacitance probe (20) adapted to be disposed in a vessel so as to be responsive to variations in capacitance as a function of material level. An oscillator (10) has an output coupled to the resonant circuit and to a phase detector (32) for detecting variations in phase angle as a function of probe capacitance. Level detection circuitry (36, 38) is responsive to an output of the phase detector and to a reference signal indicative of a level of material for indicating material level as a function of a difference between capacitance at the probe and the reference signal. In the preferred embodiments of the invention disclosed, an automatic calibration circuit (34) adjusts the resonance characteristics of the parallel resonant circuit in a predetermined or preprogrammed manner during a calibration operation to a point indicative of the predetermined reference material level. A timer (42) measures the duration of the automatic calibration operation for indicating conditions at the probe, such as the amount of material coated onto the probe. A reed switch (52) is positioned adjacent to the cover of a housing which encloses the electronics and is responsive to variations in magnetic flux from externally of the housing for indicating a calibration operation without removing the housing cover.

Abstract: A process of alkylating isoparaffinic hydrocarbons with olefinic hydrocarbons in the presence of an acid catalyst which comprises the steps of reacting isopara­ffinic hydrocarbons and olefinic hydrocarbons in the presence of acid catalyst in a reaction zone (2) to form alkylate, withdrawing a mixture of hydrocarbons with acid catalyst as effluent from the reaction zone, separating the effluent into an acid phase and a hydrocarbon phase in a first separating zone (16), reducing the pressure on the hydrocarbon phase to refrigerate it and vapourize volatile hydrocarbons, passing the refrigerated hydrocarbon phase in indirect heat exchange with the reaction mixture of hydrocarbons and catalyst in the reaction zone to remove exothermic heat of reaction and vapourize further volatile hydrocarbons in the hydrocarbon phase, separating the liquid portion of the hydrocarbon phase from the vapour portion thereof in a second separating zone (25), fractionating the liquid portion of the hydrocarbon phase to remove alkylate, passing the vapour phase material removed in the second separating zone through a compressor (34) and a condenser (36) to compress and condense the vapour phase to form a liquid phase, reducing the pressure on the liquid phase to refrigerate it and vapourize volatile hydrocarbons forming an isoparaffinic hydrocarbon liquid phase and a volatile hydrocarbon vapour phase, separating the refrigerated isoparaffinic hydrocarbon liquid phase from the volatile hydrocarbon vapour phase in a third seaprating zone (39), and adding the separated refrigerated isoparaffinic hydrocarbon liquid phase as a reactant in the reaction zone, in which:
     (a) the compressor (34) is operated at a suction pressure greater than atmospheric pressure, which suction pressure is equal to the pressure within the second and third separation zones;     (b) the reaction within the reaction zone is carried out at a temperature less than 10°C (50°F); and   (c) heat exchange apparatus is provided having a thermally conductive wall with an enhanced boiling surface on one side of such wall for carrying out the indirect heat exchange of the refrigerated hydrocarbon phase with the reaction mixture, wherein the refrigerated hydrocarbon phase is in contact with the said enhanced boiling surface during the indirect heat exchange.

Abstract: An improved filler wire feed controller for a welding system is described in which the filler wire (5) can be supplied to the vicinity of an arc between an electrode (10) and a workpiece (13) in a four-portion cycle. The cycle can include a feed portion, during which the wire is supplied to the weld pool at a rate at which it is consumed and deposited on the workpiece; a retract portion, during which the wire is rapidly withdrawn from the workpiece; a pause portion, during which the wire is stationary with respect to the arc; and an advance portion, during which the wire is advanced rapidly into the arc. This four-­portion cycle provides increased flexibility of control of supply of wire to the weld pool (12), which can be employed to avoid balling of the end of the wire (5). The wire feed supply may be synchronized to variations in the current of the arc and also to movement of the wire guide/electrode assembly with respect to the workpiece.

Abstract: Method and apparatus for softening water. The process of the invention consists in aerating water and in heating in order to precipitate rapidly the calcium carbonate dissolved up to a carbonate hardness of less than 6 French degrees. The only reactants necessary for this softening are compressed air (supplied, for example, by a compressor) and heat energy. The aerated water loses its carbon dioxide and tends to precipitate CaCO3. Heating accelerates this precipitation. The invention applies to all waters with a carbonate hardness higher than 6 French degrees. <IMAGE>
