Abstract: Abstract of the Disclosure The legs of the landing gear of a semi-trailer may be automatically extended and retracted by a pneumatically operated actuator adapted to be connected to the crankshaft of the landing gear and adapted to rotate the cross-shaft of the landing gear selectively in either direction at a high or low speed. The crankshaft is rotated by gears and ratchets which are driven by pawls adapted to be reciprocated by an air-actuated cylinder and adapted to be alternately positioned in active and inactive positions. The flow of pressurized air to the cylinder is controlled by a cycle valve and an on-off valve, the latter being capable of turning off the actuator automatically when the legs are fully retracted.

Abstract: PROCESS AND APPARATUS FOR MULTIPLE-STATION            RESISTANCE WELDING     ABSTRACT     Several electrodes (6) are mounted, electrically insulated, to a joint power transmission plate (5).  Each electrode (6) is associated with an isolating switch (30) by means of which the electrode can be galvanically connected to the plate (5).  The plate (5) and a second power trans-mission plate (10) carrying the counter electrodes (11) are connected to the terminals of a single source of welding current.  The workpieces are clamped between all of the electrodes (6) and counter electrodes (11).  Thereupon, preselected groups of the electrodes (6) are supplied in succession with the welding current.         By means of the apparatus, very many, closely adjacent sites can be welded in a small space, while the workpieces, secure against deformation, are clamped between all of the electrodes and counter electrodes.

Abstract: Abstract Anaerobically-curing compositions are described comprising (A) a polymerizable monomer; (B) a halogen-containing compound as a first initiator component; (C) an organic thiol as a second initiator component; and (D) an inhibitor of free-radical polymerization.  These composi-tions are particularly suitable as adhesives and may be formulated as thread-locking adhesives, or may be modified by the addition of various modifying polymers to obtain desired properties such as increased viscosities or pressure-sensitive properties.  Since the compositions of the present invention contain no peroxides or hydro-peroxides, they may be stored for extended periods of time without the fear of initiator decomposition and may be manufactured without the possibility of explosion.

Abstract: DIFFRACTED ENERGY AUTO-RANGING SYSTEM           FOR A CAMERA     ABSTRACT OF THE DISCLOSURE           An infra-red auto-ranging system for a photographic camera or the like includes a ranging sensor that directs a portion of the light energy from the subject of principal interest through a diffraction device that diffracts the radiation into central and higher order spectral lines that are then passed through an infra-red filter.  An infra-red responsive sensor, such as a photo-responsive reticon array, is positioned to receive the radiation from a selected one of the spectral lines with the position of the imaged spectral energy on the sensor varying as a function of the angle of incidence of the light from the subject and of the range to the subject. The diffraction device may take the form of a conventional transmission-type diffraction grating, a replica, or an acousto/optical diffraction cell responsive to an excitation energy source. Computing circuitry is provided to determine the range to the subject of principal interest. as a function of the position that the selected spectral line images on the sensor.  By appropriate selection of the diffraction characteristics of the diffraction device, it is possible to limit the width of the selected spectral line to a narrowly defined physical limit to enhance the resolution of the ranging determination.

Abstract: ABSTRACT OF THE DISCLOSURE           A repeating hemostatic clip applying instrument is disclosed.  Shaped like a pair of dog-nosed pliers, the other ends of the jaws are adapted to hold a clip which may be applied to a blood vessel with the instrument.  The rear-ward portion of the jaws overlap and a rectangular channel is formed in one of them through which clips may be pushed by a pusher extending down the center line of the instru-ment.  One of the jaws is adapted to receive a cartridge containing a stack of U-shaped clips which may be pushed one at a time to the distal end of the jaws by the pusher. The instrument basically comprises only three pivoted members, the pusher and its operating linkage, and one or two springs.  Several forms of pusher-actuating means are disclosed, two of these include a bell crank and cam so that the pusher will be operated before the jaws can be closed.  The third comprises a free bell crank and a pair of unbalanced springs to achieve the same object.  The cart-ridge is provided with a spring for urging the U-shaped stack of clips down to the pusher channel, and a clip follower for preventing misalignment of the clips in the cartridge.  These above and various other features operate together in a synergistic manner to apply a plurality of hemostatic clips in a surprisingly simple, light instrument providing an almost conventional "feel"

Oxygen enriched air is delivered to the patient during the inspiration period such that the pressure waveform is a ramp func-tion having initial and final values which are dependent on the resis-tance, compliance and alveolar volume of the lungs.  The apparatus includes a source of oxygen enriched air at a regulated pressure and a pneumatically controlled pressure reducing valve for reducing the pressure of the oxygen enriched air for delivery to the patient.  The valve is controlled by a transducer which converts an electrical con-trol signal into a pneumatic control signal.  The electrical control signal which is generated by an electronic control circuit, is a func-tion of the parameters of the patient's lungs.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a generator system connected to an external A.C. power source for supplying electrical A.C. power to a load for prolonged periods when the external electrical A.C. power source fails.  The system comprises a main A.C. generator unit capable of generating an A.C. potential at a selected frequency and voltage for the load, and an auxiliary A.C. generator is connected to the main generator for generating A.C. at a high frequency.          This high frequency A.C. is conveyed to a relatively small high speed motor and flywheel unit in a sealed chamber, which unit at full speed can store large amounts of rota-tional kinetic energy.  The high speed motor has a stator armature with a power winding and an excitation coil, and a cooperating rotor of soft magnetic material having a cylindrical surface with a layer of magnetizable permanent magnet material thereon.  When energized with the high fre-quency A.C., the power winding causes the rotor to rotate as a hysteresis motor.  When the external electrical A.C. power source fails, the excitation coil is energized with high frequency A.C. to magnetize the layer of permanent magnet material into a pattern of north and south magnetic poles which will enable the rotational kinetic energy of the rotor and flywheel to generate high frequency A.C. of constant frequency in the power winding which is supplied to the auxiliary generator to cause it to function as a synchronous motor to drive the main A.C. generator so that it will keep on producing the A.C. potential to the load.

Abstract: Abstract The invention relates to a process for the recovery of valuable metals from sulfidic, silicate-containing raw materials by slurrying the raw material in water, by subjecting the slurry to a selective leach under atmospheric conditions and in an acidic milieu, and by separating the valuable-metal containing solution from the solid leach residue.            When the leach is carried out by introducing an oxygen-bearing gas into the slurry which contains finely-divided sulfide and carbon, the acidity of the slurry drops in a controlled manner so that a high efficiency of oxygen, and a high selectivity of the leach as regards valuable metals, are obtained. Owing to the presence of carbon the oxygen is reduced very easily and so oxygen efficiency is high and the rate of dissolving of the valuable metals increases in the slurry mixture.
