Abstract: A method of making a cast-in-place prestressed pile by means of a movable casing set composed of some separable casings which can be displaced vertically, and pull and push each other after displacing. Reinforcing cage and prestressing strands can be placed within the casing set. After grouting, each section, the casings can be pulled out one by one with an external force to overcome friction between the earth and casings till complete removal of all casing, a cast-in-place pile is then formed, and the movable casing set can be used at another spot.

Abstract: A therapeutic powder is manufactured from the bark and outer layer of sap wood from the tree, Mimosa Tenuiflora poir. The bark and wood is chemically and manually washed, then roasted to separate the curative active ingredients from the cells containing the active ingredients, and then ground into the powder of the invention. The ground powder is then sterilized. The powder is therapeutic when applied to burns, wounds, lesions and other skin injuries.

Abstract: In an infrared flame detector system an infrared photodetector is positioned to receive infrared radiation from the flame to be detected. The output of the infrared flame detector is amplified with a gain readily switchable between two different gain values. The amplified output signal is filtered by a programmable high pass filter, in which the corner frequency can be selected to have different values and is readily switchable between two different values to correspond with different fuels generating the flame being detected. The output of the programmable filter is full wave rectified to provide a DC signal level corresponding to the AC signal generated across the photodetector. This DC signal level is compared with a reference signal voltage selected to correspond with the signal voltage produced when no flame is present, to provide an indication of the presence or absence of a flame.

Abstract: In an industrial process control system, in which a plurality of remote stations interconnected by a communications link each control and manage a plurality of input/output devices, each remote station comprises a primary data processor and a back-up data processor. The primary data processor normally exercises control over and manages the input/output devices, but, should the primary data processor fail, the back-up processor takes over management and control of the input/output devices. Periodically, the primary data processor transfers status data relating to its operation in the control of the input/output devices to the back-up data processor via a dual ported memory connected between the two processors. The back-up processor maintains a record of the status data and updates its record of the status data with the periodically transferred copy of the status data.

Each of the panel elements (10) has several cut-out sections (12) in its borders (11). In each of the cut-out sections (12) there is inserted a rod (13) running essentially in the same direction as the border. Each of the bracing elements has the shape of a clamp (20) which can be inserted into the cut-out sections of adjoining panel elements (10) and whose rods (13) are shaped for gripping, preferably to establish a drop-in connection (FIG. 1).

Abstract: In a calibration system for optical instruments of the type which make measurements at incrementally spaced wavelengths throughout a spectrum, a plurality of standard samples are measured by a master instrument and a field instrument. The measurement data obtained from each instrument are then statistically correlated to determine a calibration file which is stored with the field instrument. The calibration file includes identification on the field instrument of index locations at which the field instrument will respond to the same wavelength as corresponding index points on the master and includes correction coefficients for each of the index locations. The calibration file is stored in a computer connected to the field instrument and the computer is provided with a program to correct the measurements made by the field instrument in accordance with the stored calibration file.

Abstract: A dual air conditioner having a pair of air conditioning units for front and rear seats within the compartment of a vehicle adjusts the temperatures of air output to the front and rear seats in accordance with the difference between the temperature desired at one of the front and rear seats and a typical temperature sensed within the compartment corrected by a function of the difference between desired temperatures in order to condition the front and rear seats to the respective desired temperatures.

Abstract: A metal gasket for a face-seal fitting has an outer section in the form of a circular annulus, an inner section in the form of a circular annulus and having a shorter axial dimension than the outer section. The inner section and outer sections are joined by a tapered section having conical faces on opposite sides thereof facing toward the axis of the gasket. A method of prolonging the useful life of a tubular element in a face seal fitting involves repeatedly engaging an end of the tubular element with the conical face and, when the end of the tubular element wears, engaging the end with a radial face adjacent to the conical face.

Abstract: In an optical instrument for measuring particles in the size range of 0.5 microns to 300 microns, a laser beam is caused to pass through a sample stream of liquid containing particles to be measured. A photodetector detects a portion of the direct laser beam passing through the sample stream and the amplitudes of the pulses generated by this first photodetector provide a measurement of particles in the size range of 10 to 50 microns. A second photodetector detects forward scattered light from the laser beam passing through the liquid sample stream. The amplitudes of pulses generated by the second photodetector provide a measurement of pulses in the size range of 0.5 microns to 10 microns and the durations of pulses generated by the second photodetector provide a measurement of pulses in the size range of 50 to 300 microns.

Abstract: An assembly for preventing accidental pricking by a hypodermic syringe includes a cap mounted on a needle hub for sliding between an extended position enclosing the needle and a retracted position exposing the needle. The cap slides on resilient bands extending arcuately from flaps projecting radially from the needle hub and structure is provided to retain the cap in both its extended position and its retracted position. The cap is tapered toward an end distal to a body of the syringe so that the resilient bands snugly frictionally engage the distal end of the cap to maintain the cap in the retracted position. In one embodiment of the invention, the flaps include portions extending radially beyond the resilient band, and the cap defines channels for receiving the flaps. The channels widen abruptly, at their ends adjacent to the syringe, to define slots into which the radially extending portions of the flaps can be twisted to lock the cap in its extended position.
