Abstract: ABSTRACT     A non-destructive method of measuring the fatigue limit of a ferro-magnetic test piece by use of the mechanical Barkhausen noise phenomenon.          The test piece is cyclically loaded with continuously or incrementally increasing amplitude in the presence of absence of a stable magnetic field by which the test piece is magnetized and, simultaneously, measurement is made of the maximum value obtained as a function of one of the effective value,  the size distribution and the mean value of the mechanical Barkhausen noise pulses induced during fatigue of the test piece.  The loading amplitude at which such maximum value is reached cor-responds to a fatigue strength equal to the fatigue limit of the test piece, the latter having been subjected to a prior loading process to create a lattice defect pattern in the test piece when no stable magnetiz-ing field is present.  The prior loading process comprises the steps of cyclically loading the test piece externally with continuously or incrementally increasing amplitude and simultaneously measuring the changes in the effective value, size distribution or mean value of the mechanical Barkhausen noise pulses induced during fatigue of the ferro-magnetic test material caused by such loading and decreasing the external loading to zero. This method  offers the notable advantage that the endurance or fatigue limit can, in practice, be determined very quickly -for example, in a period of only 15 minutes.  Therefore, the method can in practice be applied to determine immediately whether or not the dynamic loading of a machine part is too large.

Abstract: CASTER BRAKE AND SWIVEL LOCK   FOR STRETCHER OR THE LIKE     ABSTRACT OF T~E DISCLOSURE     An improved system for actuating wheel engaging 'ring brakes for a hospital stretcher, bed, or the like.  The brake includes an elongated rotational member extending longitudinally along the stretcher to actuate pivot arms adjacent one front wheel and one rear wheel to prevent the wheels from rolling.  A separate elongated rotational member extends the length of the stretcher and actuates a bullet pin latch to lock a nonbraked wheel against swivel action.          Thus, a single nurse can easily push and manipulate the stretcher about a hospital even when loaded with a patient.

Abstract: ABSTRACT OF THE DISCLOSURE        A mechanism for transferring a wheelchair through a side door opening of a motor vehicle includes a hoisting device disposed in the vehicle and a linkage linking the chair to the hoist.  Once hoisted off the ground, the wheels of the chair are retracted and the chair is swung by the parallel links through the door opening.  The chair is suspended at a rear corner of a generally box-like frame so that final pivoting of the chair about its point of suspension not only brings the chair to its front facing position in the vehicle but simultaneously completes its sideways movement into the vehicle.  The chair is then lowered into its seated position.

Abstract: Abstract Purification of cuprous chloride is accomplished by distillation wherein cuprous chloride is recovered as the overhead product, and substantially all of the silver chloride and other impurities present report Lo the bottoms.  Typical. impurities in copper ore leach liquors include chlorides of silver, calcium, arsenic, bismuth, iron, nickel, lead, anti-mony, selenium, tellurium, silicon, mercury, manganese, tin, aluminum, magnesium, chromium, cobalt, cadmium, molybdenum, zinc and titanium, most of which may be excluded in large part by crystallization of cuprous chloride.  Measurable amounts of these impurities, however, report to the crystals, and silver tends to co-precipitate with the copper in major amounts.  Distillation accomplishes a high degree of copper-silver separation and substantial elimination of other impurities from the copper.

Abstract: ABSTRACT OF THE DISCLOSURE    Polyurethane resins are described having high impact strength and other structural strength properties, and significantly improved resistance to deformation by heat.  The properties of these materials are such as to make them comparable to engineering thermoplastics such as nylon and like materials commonly used to fabricate structural components such as automotive parts, equipment housing, sporting goods, furniture, toys, household and like consumer goods.    The resins are prepared from organic polyisocyanates, an isocyanate-reactive material (polyol, polyamine, etc.) having an average functionality of at least 1.9, a Tg less than 20°C and molecular weight of 500-20,000, and one or more low molecular weight extenders the major distinguishing feature being the markedly lower proportion by weight (2 to 25 percent) in which the isocyanate-reactive material is employed as compared with polyurethane resins conventionally prepared in the art.  Depending upon the particular combination of reactants employed the polyurethanes of the invention can be thermoplastic or thermoset and can be prepared in both cellular and non-cellular form.

Abstract: ABSTRACT OF THE DISCLOSURE A system for transmitting an emergency call from a person requiring assistance.  The system includes an emergency calling device coupled via a telephone exchange system to an emergency call receiving center having an operator.  The calling device automatically dials a predetermined emergency telephone number upon actuation of a sensor by the person requiring assistance for placing a call to the emergency center.  A first data device is provided for transmitting predetermined emergency data by frequency keying in the voice band to the emergency center.  An intercommunication set in the calling device establishes a voice connection between the person requiring assistance and the emergency center operator.  The intercommunication set is switchable between states of voice transmission and voice reception.  A first control unit in the calling device is responsive to a first operating mode control signal for switching in the first data device and switching out the intercommunication set, and is responsive to a second operating mode control signal for switching in the intercommunication set and switching out the first data device.  In the emergency center a control unit controls the transmission of a control tone to the calling device.  The control tone constitutes the first operating mode control signal and the lack of the control tone constituting the second operating mode control signal.  A second data device in the emergency center selectively transmits voice direction control signals by frequency keying in the voice band for controlling the state of the intercommunication set in the calling device.

Abstract: ABSTRACT           .      A cathode for oxygen reduction in a fuel cell is formed from a host matrix including at least one transition metal element which is structurally modified by the incorporation of at least one modifier element to enhance its catalytic proper-ties.  The catalytic body is based on a disordered non-equilibrium material designed to have a high density of catalytically active sites, resistance to poisoning and long operating life.  Modifier elements, such as La, Al, K, Cs, Na, Li, C, and O structurally modify the  local chemical environ-ments of a host matrix including one or more transi-tion elements such as Mn, Co and Ni to form the catalytic materials of the cathode.  The catalytic materials can be deposited as a layer on the sur-face of a porous electrode substrate to form a gas diffusion cathode or can be formed as a gas diffu-sion electrode.

Abstract: CONTINUOUS FLOW METERING APPARATUS       ABSTRACT OF THE DISCLOSURE     New apparatus and methods are disclosed using liquid position sensors in conjunction with flow-stopping valves to control (meter) fluid, e.g. sample/reagent/air, aspiration into a single conduit, such as in a continuous flow system.  Air or other gas separates selected ones of the liquid segments.  The volume of the aspirated segment is established by sensing a flow parameter of the segmented stream of a selected one of the sensors. A pulse is generated by the sensors (detectors), for example due to the change of light intensity at a liquid-air interface traversing the conduit.  The signal pulse from a sensor causes the actuation of a selected one of the valves and stops aspiration (flow) of the liquid by traversing the flow path in the conduit through an air segment.  The valve cuts through air only. Therefore, the body of the valve does not contact reagent or sample liquid by this action and the risk of carryover contamination is avoided. With the aspiration cycle completed, the input end of the conduit, e.g. an aspirating probe, can consequently be immersed in different media and the cycle repeated.
