Abstract: Title Axle Locking Differential Device An axle locking device designed for installation in a standard vehicular differential case is defined by two mating unitary bodies piloted between a cross member and the interior walls of the case. In a preferred form, the halves are symmetrical, each half including a pair of pilot surfaces defined by cradles which engage the cross member. Other pilot surfaces are disposed in three orthogonal planes for engagement with the interior wall surfaces of the case, particularly the axle and cross member bore areas. Collectively, the pilot surfaces of the locking device eliminate any requirement for positive securement by fasteners of the locking device to either the cross member or the interior walls of the case.

Abstract: Abstract of the disclosure:         The alkali metal and alkaline earth metal salts of diarylphosphinic acids are prepared by reacting tri-arylphosphane oxides with alkali metal or alkaline earth metal hydroxides in a molar ratio of about 1:1 or 0.5, in the presence of water, under elevated pressure and at elevated temperature.  In this manner, the alkali metal or alkaline earth metal salts of diphenylphosphinic acid are formed from triphenylphosphane oxide, which is the preferably used triarylphosphane oxide.       Other salts or the corresponding free diaryl-phosphinic acids can, if desired, be obtained from the alkali metal and alkaline earth metal salts in a conven-tional manner.  The products are principally intermedi-ates in various fields.

Abstract: ABSTRACT OF THE DISCLOSURE                  COMMUNICATIONS SYSTEM        A communications system employs a laser for producing a beam of spatially-coherent, monochromatic, aperture-limited electromagnetic optical energy.  The beam is modulated with intellegence-bearing information to develop wavefronts of mutually-aligned orientation. The beam is directed through free space to impinge upon a surface reflective of the energy and exposed in a non-confined free space to the impingement of the beam. The beam is also focused upon the surface with the impingement of the beam being within the depth of focus and substantially at the waist of the region of focus of the beam.  The information in the beam, as reflected by the surface at an angle thereto and with a mutually-aligned orientation of those wavefronts maintained, is detected.  Finally, the information demodulated from the detection is derived and utilized.

The temperature of the casting mold,  before and after its filling with molten metal, is regulated by controlling the powers of the cooling and the heating systems arranged within the casting mold.   During the solidification of the cast body until its removal, there is regulated the deformation state of the system cast body mold by controlling the clearance and the force of seizing between the cast body and the walls of the casting mold.    Both furnaces are arranged in front of the casting machine on receiving devices, carried by a horizontally movable shuttle in left or right position,  and in these positions there are provided devices for metallurgical pretreatment and systems for temperature pretreatment of the molten metal in the furnaces.

Abstract: ABSTRACT A pipe handling apparatus is adapted for transferring oil well pipe to and from a drilling rig. The apparatus includes a transportable chassis having tracks for supporting and guiding a reciprocable and rotatable table. A first scissors lift mounted to the table provides vertical motion to a platform on which is mounted a second scissors lift. The second scissors lift is designed to impart vertical and horizontal motion to a conveyor. The conveyor comprises three axially spaced endless belts for moving the pipe longitudinally to the conveyor takeoff point. Tapered spades protrude into the spaces during the pipe return operation to eject the pipe from the conveyor. The conveyor and platform are reciprocable with respect to the second and first scissors lifts, respectively. The chassis includes pivotable arms for raising a pipe to the top of the collapsed scissors lifts so that a pipe rolls onto the conveyor belts prior to lifting.

Abstract: ABSTRACT OF THE DISCLOSURE    A physiological sensor for use with a pacemaker (16) is disclosed.  The sensor allows the rate at which the pacemaker delivers electrical stimulation pulses to the heart (18), or the escape interval during which a natural heart event must occur before an electrical stimulation pulse is delivered, to be  adjusted  as  needed  in  order  to  satisfy  the  body's physiological needs.  The sensor utilizes the measured time interval between an atrial stimulation pulse, A, and the responsive atrial or ventricle depolarization as determined by an interval measurement circuit (71), as a measure or indication of the physiological demands placed on the heart. The time interval between a ventricular stimulation pulse, V, and the responsive ventricular depolarization may also be used as a measure of physiological need, and hence as an alternative criteria for rate control.    Atrial depolari-zation is sensed by detecting a P-wave, and ventricular depolarization is preferably sensed by detecting an R-wave. P-wave and R-wave sense amplifiers (48, 54, 56), connected to an  atrial  pacing/sense  lead   (22)   and   a  ventricular pacing/sense lead (30), are used to perform this sensing function.  The A-P, A-R, or V-R intervals thus measured are processed in a physiological detector  (73)  in order to ascertain if these intervals are increasing or decreasing. If, over several heart cycles or beats,  an increase or decrease  in  these  measurements  is  detected,  the  pacing interval set by the pacemaker's pulse generator logic (42) is adjusted in an appropriate direction in order to adjust the heart beat rate accordingly.

Abstract: ABSTRACT OF THE DISCLOSURE     An infinite impulse response (IIR) filter is operative to filter an input signal that comprises a sequence of digital words spaced in time by an interval T. The filter includes delay means that delays the input signal by successive increments of time equal to T so as to cause the production of a series of relatively delayed signals in which each signal is delayed by T with respect to the previous signal in the series. IIR processing units receive respective groups of the series of signals, the groups being offset with respect to one another by one word. The units are operative during each of plural successive clock periods equal to 2T to process respective sets of words obtained from the respective groups of the series of signals so as to produce two output words. A multiplexer combines each two output words produced during each clock period equal to 2T to constitute Q filtered output signal comprising a sequence of output words spaced In time by the interval T.
