Abstract: ABSTRACT OF THE DISCLOSURE              .            A swimming pool wall, for placement in an excavation, is made up of a series of bendable plates having only vertical flanges for stiffening while permitting shaping the wall to a selected outline.  A resilient coping strip embranes the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration.  Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, ex-tend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron.   Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation.  After back-filling and forming the apron, those bars are removed.

The catalyst support elements are each compressed at one end into contact with a gasket member in each retaining portion by force applying means positioned so as to contact the other end of a plurality of catalyst support elements at one time.  In one embodiment, the various elements of the apparatus are formed of materials having different coefficients of expansion and related lengths so as to maintain compression without the use of specific spring elements.  Other embodiments use springs to compress either a single catalyst support element at a time or several at once.

Abstract: PRESSURE MONITORING METHOD AND APPARATUS                         ABSTRACT     An apparatus which measures and monitors the pressure within a human body includes a pressure sensor having a housing closed by a pressure sensitive diaphragm to define a plenum, an exhaust tube mounted within the plenum which terminates adjacent the inner surface of the diaphragm, And tubes which transmit a substantially constant flow of gas into the plenum and which withdraw gas from the exhaust tube to a location remote from the body.  Changes in pressure within the body cause the diaphragm to alternately close and open the end of the exhaust tube, thereby resulting in an increase or decrease in the pressure within the plenum until an equilibrium pressure is reached.  A source of gas pressure is provided, as well as a means for providing a substantially uniform flow rate and means for measuring the pressure within the tube that transmits the gas flow to the sensor.  The flow rates to and from the sensor are compared, and the flow of gas to the sensor is cut off if the flow rates are unequal, a condition indicative of a leak in the sensor or in the tubing that transmits the gas to and from the sensors.

Abstract: ABSTRACT            The strength and functional integrity of a thermally formed surgical device made from a polymer of p-dioxanone are improved by drying the thermally formed device at a temperature of less than 30°C to remove subs-tantially all moisture from the device.  The dried device is then heated in a dry, inert atmosphere at a temperature of 50°C to 90°C for a period of time sufficient to increase the crystallinity of the device to at least 43%.  The resultant new product comprises a thermally formed sur-gical device made from a polymer of p-dioxanone having a density of at least 1.384 grams per cubic centimeter and a crystallinity of at least 43%.  The new surgical devices of the invention also have improved audible and tactile properties as well as improved shelf-life.

Abstract: ABSTRACT             A control valve arrangement adapted to produce and maintain a pilot signal comprises a number of standard modules.          The basic element has two standard modules, each of which includes a diaphragm-controlled on-off valve.  An input signal is applied to a first valve against a reference pressure such that when the valve is on, a signal is generated and held as a pilot pressure.          A second valve responds to a fall in input signal pressure to cancel out pilot pressure.  The two valves together constitute a bistable operator.  A particular use of this operator is in a railway braking system in which the first valve is used as an application valve and the second valve is used as a release valve.          A third module may be used as a pilot pressure-maintaining valve.

Abstract: COMPOSITE LEAF SPRING                          Abstract A composite leaf spring for use in a vehicle suspension system having a pair of metal outer skins and a stiff plastic core bonded between the skins.  The core can be made of any one of a variety of filled or unfilled polymers which has a rela-tively high shearing strength and sufficiently isotropic proper-ties so as to handle stresses in all directions.  An important aspect of the invention is that it provides for a simple and inexpensive method for manufacturing a contoured composite leaf spring which includes the steps of first positioning the skins in a spaced relation within a female mold and then pouring or injecting the core material into the space between the skins.          Preferably, the skins are of uniform width and thickness to reduce manufacturing costs.  In most common vehicle applica-tions, the spring would have a point of maximum thickness in the central section where the bending moment is greatest and would be tapered toward each end.  The spring skins should meet the following criterion:         If F equals the static loaded force (in lbs) exerted on the spring, which is supported at its ends;         L equals the length of the spring (in inches) between the end supports;         N equals the number of composite leaves in the spring (each leave comprising two skins bonded to a core); and Ts equals the thickness (in inches) of each skin in each composite leaf;       Then:             .

Abstract: Abstract:    Herein disclosed is a method for automatically controlling both the running operations of traveling machines including a pusher machine, a charging car, a coke guide and/or solely a quenching car.  Transposed-pair-type inductive radio lines capable of data transmissions are arranged over the whole length of the running path of the respective traveling machines.  The absolute addresses of the working machines are continuously located at a central control system by means of a continuously position detect-ing mechanism resorting to an absolute address detecting method.  Instructions to consecutively effect the running, stopping and working operations of the traveling machines are generated by grasping the positions and working states of the traveling machines on the basis of the control programs of the respective central addresses and the respective working steps, all of which are stored in the main controller, and on the basis of the speed and work data fed from the working machines, and the positions and working states of the same machines.

Abstract: Abstract A system for recovering data, both prerecorded and user data, from a reflective optical data storage medium, with the further capability of distinguishing data from foreign particulate matter on the data disk.  A pair of detectors measures the fraction of light reflected from and trans-mitted through the data disk and, knowing the fraction of light absorbed by the disk, distinguishes user data from prerecorded data and particulate matter.  The data disk has different optical characteristics for prerecorded and user data, the prerecorded information being black, highly absorptive silver, while the user data consists of pits of relatively high transmissivity in a reflective field.  Particulate matter is recognized by intermediate reflectivity and transmissivity.  The optical characteristics of the material are enhanced or exaggerated so that the two types of data and particulate matter can be distinguished.
