Abstract: LAMINATE FOR WEARING APPAREL AND METHODS FOR THE         MANUFACTURE OF THE LAMINATE            ABSTRACT OF THE DISCLOSURE      Methods are provided for producing a laminate particularly useful in producing warm moisture-resistant wearing apparel for industrial applications and sportswear . The laminate is superior in flex-ibility and comfort when worn while still providing appropriate moisture protection.   In addition, the method includes procedures for providing a combined textured and creped surface for varying the ap-pearance and degree of flexibility and "feel" to garments comprised of the laminate.  The methods include joining a non-woven fibrous web such as a needled felt to a foamed synthetic resin web, such as polyurethane foam, and thereafter, through controlled tension,  temperature and roll pressure, joining a film,  such as a synthetic resin film, to the exposed foam surface through a heated roll nip, followed by embossing.  The degree of "crepe" and texture or embossing imparted to the laminate varies inversely to each other, as desired, to provide a variety of different appearing and appealing fabric surfaces.

Granted: 1987-04-28
Abstract: Abstract A rotation control system for the mattock means (2) of a tuft-building forest mattock, whereby rotation of the mattock means is adapted to be braked or stopped stepwise in a manner that each pick (3) in turn works a whole in the first stage, in the second stage said pick (3) of the mattock means removes surface deposit from between the obtained hole and a tuft to be built, and in the third stage, as mattock means (2) is allowed to rotate freely, pick (3) leaves the loosened earth behind as a tuft.  In order to make the sticking angle and depth dictated by the start moment of braking stages readily adjustable according to various qualit-ies of soil, at a certain angle of rotation of said mattock means a first impulse sensor actuates a first delay timer (6), adapted after a settable delay time to turn on a brake (11) for setting out the first stage of mattock means (2).  At a certain angle of rotation of said mattock means, a second impulse sensor (5) actuates a second delay timer (7), adapted after a certain delay time to turn on said brake (11) for setting out the second stage of mattock means (2).          The duration of the first and second stage, i.e. the braking effect stopping the rotation of mattock means (2), is adapted to be controlled each by its own timer (8 and 9) whose setting time is adjustable.

Abstract: CALIBRATION OF A SYSTEM HAVING PLURAL SIGNAL-CARRYING CHANNELS            Abstract of the Disclosure In a system having plural signal-carrying channels, a phase shift is introduced between a signal in one of the channels and a reference signal for calibrating the individual channels.  The phase shift is introduced by phase-shift apparatus responsive to a command signal directing the continuous monotonic increment of phase.  The apparatus may be contained within each channel for use in the signal-carrying process, or may be placed in the reference channel for use solely in the calibration process.  The phase incrementing introduces a frequency shift (a serrodyning) which produces a beat-frequency signal upon mixing a channel signal with a reference signal.  The beat-frequency signal is phase locked to a modulation pattern of the command signal whereby a measurement of phase (or delay) can be made between the two signals for calibration of each channel within the system.

Abstract: METHOD OF DETERMINATION OF WEIGHTING MATERIALS AND LOW GRAVITY SOLIDS IN DRILLING FLUIDS            ABSTRACT OF THE DISCLOSURE        Normally, concentration of weighting agents such as barium sulphate is calculated by retort distillation to dryness and by means of a relatively inaccurate mate-rial-balance equation.  The present process utilizes the fact that weighting agents have a specific gravity higher than the specific gravity of the low gravity solids such as bentonite, etc. present in the drilling fluids.  A sam-ple is mixed with a liquid known as a developer liquid which has a specific gravity higher than the low gravity solids which therefore float on the developer, but lower than the weighting agent which sinks in the developer. The mixture is preferably centrifuged to force the weight-ing agent out of the drilling fluid and into the developer liquid after preferably lowering the viscosity of the dril-ling fluid.  The settled heavy gravity solids (weighting agent) may then be removed, dried and weighed or prefer-ably the volume is read directly on a suitably graduated centrifuge tube in which the settling process has taken place.  By calibration with fluids containing known con-centrations of the weighting agent, the volume readings can readily be converted into concentration units.

Abstract: METHOD OF CONTROLLING A SPACE HEATING SYSTEM                  ABSTRACT OF THE DISCLOSURE     A method of controlling a space heating system having a plurality of electrical resistance heaters includes the steps of computing the aggregate number of resistance heaters required to be energized to raise the actual temperature within a space to a set point temperature. This aggregate number may have integer and fractional components.  One of the resistance heaters, denominated a controlled heater, is adapted both for continuous energization or for modulated control by intermittent energization.  A group of second resistance heaters is adapted for continuous, staged energization, this group including a number of heaters equal to the integer component.  Energization of the heaters comprising this group is preferably sequential after the lapse of a preselected interstage time delay between energization of the controlled heater and the first heater of the group. Similarly, time delays will be interposed between the time of energization of the first heater of the group and the times of energization of succeeding beaters in the group. The aggregate number is repetitively recomputed, and the heater comprising the group of second heaters are successively energized or de-energized in a quantity equal to the integer component,  The controlled heater is energized for an average time which is equal to the fractional component.  As the actual temperature approaches the set point temperature such that the integer component becomes zero, all heaters in the group are de-energized and when the actual temperature is equal to the set point temperature, the controlled heater is also de-energized.

Abstract: ABSTRACT   The  purification  of  aluminum  chloride,  with  the crude aluminum chloride normally being obtained through a process of  carbo-chlorination of  metallic ores,  in particularly aluminum bearing ores, to make the metallic chlorides,  in particular  aluminum  chloride.    In  the present invention,  if the crude aluminum chloride does not contain traces of sulfur, the crude aluminum chlo-ride is blended with elemental sulfur or an equivalent sulfur containing compound and simultaneously elemental aluminum  powder  or  an  equivalent  aluminum  containing compound in the solid state is added to the crude alumi-num chloride.  This blend is kept at 180°C at one atmos-phere of pressure and is fed into a screw-type sublimer wherein the substantially pure aluminum chloride under-goes sublimation in the presence of elemental nitrogen as a purging agent and under constant agitation.   The sublimed aluminum chloride is streamed into a reaction ground bed containing aluminum granules at approximately 250°C  for  removal  of  the  traces  of  elemental  sulfur therefrom.   The  then pure  aluminum  chloride,  in  the vapor state, is condensed for subsequent collection.  If necessary, the aluminum chloride may be further purified through a rectification column and subsequent collection thereafter.
