Abstract: ABSTRACT This invention is a heating and cooling wall panel that accomplishes heating by radiating to bodies in a space thermal energy from a sourse of warmed water delivered to the panel at low pressure, and cools bodies in a space by absorbing thermal energy radiated to the panel from those bodies and passing the heat thus gained to a cooled fluid also delivered at low pressure. The heat transfer by this panel is accomplished when only small temperature differentials exist between the fluid and the space owing to the extreme thinness of the radiating-cum-absorbing panel face which serves to separate the space and the fluid, and owing also to the thermal connection of this thin sheet to an element which intimately embraces the fluid within the panel core. This internal element also imparts strength to the active face sheet permitting this sheet to be very thin indeed. The use of an essentially direct flow path for the fluid behind this sheet permits the fluid to be passed through the panel at very low pressure, further relieving the panel face of withstanding inordinate internal pressure thus further permiting the thinness of the face sheet.   The combination of these conditions makes possible a heat transfering panel which is simple in design and operation, is light, easily constructed and installed, inexpensive, and functions efficiently with fluid only slightly warmed or cooled and delivered at low pressure, thereby rendering this panel ideal for a vast number of energy saving application.

Abstract: ABSTRACT OF THE DISCLOSURE     A durable three-component hose comprises a nylon tube, a reinforcement of one or more plies of synthetic yarns or monofilaments wound or braided or spirally wrapped over the tube, and a melt-extruded polyolefin cover.     Extraordinary burst strength is achieved by using a mixed reinforcement, in which some of the plies or wrappings are capable of being bonded with the nylon tube, and in which other plies or wrappings are capable of bonding with the polyolefin cover.  In a typical construction the reinforcement is bonded by solvating the nylon tube surface with resorcinol so that nylon yarns of the applied reinforcement will bond therewith and the olefin cover - e.g. polypropylene to which a minor portion of EDPM or SBR rubbers has been admixed - is bonded to that portion of the reinforcement which is polyolefin, for example polypropylene yarns or monofilaments.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for scrubbing undissolved impurities from the upper portion of an ion exchange resin filtration bed is disclosed wherein air is introduced in the upper portion of the bed and develops a pressure within the vessel.  This pressure subsequently forces rinse water down through the upper portion of the bed and out of the vessel.  The gas is introduced into the bed and the water is drained therefrom at a level below the bed's upper surface but above a substantial lower portion of the resin bed. In this manner, lesser quantities of scrubbing fluids are required and the majority of the resin material is left undisturbed to maintain maximum ion exchange capacity.

Abstract: Abstract of the Disclosure Readily available digital logical circuit components are arranged in circuitry for enhancing demodulation of binary frequency shifted or phase shifted modulation signals in the presence of a received carrier wave and inhibiting demodulation in the absence of any recognized carrier wave. The circuitry is arranged for counting impulses as received including noise impulses which penetrate an input band-pass filter.  The preponderance of signal impulses lie within predeterminable limits, however, and the circuitry is arranged for opening electronic gating circuits within such predetermined limits and holding them open despite some noise impulses passing the filter. The circuitry is further arranged for integrating the signal impulse train and triggering the subsequent stages of the receiving system accordingly.  The electronic circuit components are conventional and also are readily laid down in semi-conductor structure of the popular types.

Granted: 1981-12-22
Abstract: ABSTRACT OF THE DISCLOSURE         The invention is concerned with a process for the manufacture of a styrene polymer modified with rubber to improve its impact strength, by polymerizing styrene in the presence of 1 to 20% by weight, based on styrene, of rubber in at least two stages, wherein, in a first stage, the styrene, which contains the rubber in solution, is prepolymerized at from 50 to 150°C in the presence or absence of inert diluents, while breaking up the disperse soft-component phase which forms during the polymerization by shearing the polymerization mixture until the quantity of styrene converted, based on the starting solution to be polymerized, corresponds to from 3 to 10 times the amount of elastomer constituent of the total amount of rubber employed and the particles of the disperse soft component phase thus formed have a mean diameter of less than 6 µm, and thereafter, in one or more further stages, the polymerization is completed by taking it to the desired conversion with reduced shearing or entirely without shearing, in mass, in solution or in aqueous suspension.  The process of the invention is characterized in that the shearing during prepolymerization is carried out in such a way that the particles have a weight-average mean diameter of less than 1 µm and a narrow particle-size distribution, and the disperse soft-component phase contains, during the prepolymeriza-tion, from 35 to 65% by weight of free or chemically bonded polystyrene segments being incorporated into the rubber component in a chemically bonded form as a polymer block or a grafted branch, the segments having a number-average molecular weight of at least 30,000.  The styrene polymers obtained exhibit not only high impact strength but also improved transparency, and may be used for packaging purposes.

Abstract: Ref: 3619.                      ABSTRACT        Friction brake apparatus includes a brake force applying member coupled via a linkage and slack adjusting means to a brake force actuator, the apparatus being characterised in that the linkage includes a one-way clutch and is arranged such that, on return operation of the brake force applying member to release the brake, the force applying member is permitted to return a predetermined distance prior to the clutch becoming effective to resist further return movement of the brake force applying member yet permit further return motion of the brake force actuator by virtue of the slack adjusting means. Slack adjusting means comprises a linearly movable input member, a linearly movable output member, and an element for transmitting a brake force from the input member to the output member, characterised in that the input and output members are constrained against relative angular movement, and in that the element is engaged with one of said members via co-operating helical thread means provided therebetween and is engageable with the other of said members via co-operable clutch faces provided therebetween and arranged such that in use the clutch faces are retained in force-transmitting engagement by the reaction forces in the co-operating helical thread means and are disengageable when said reaction forces are removed or relieved thereby to permit relative rotation, and hence relative linear displacement corresponding to the slack to be taken up, between the element and said one member in engagement therewith via the co-operating helical thread means.

Abstract: ABSTRACT OF THE DISCLOSURE:       When a highly resistive GaAs film doped with a metal impurity such as Fe, Ni or Cr is epitaxially grown, a metallo-cene of this metal impurity such as Fe(C5H5)2, Cr(C5H5)2, or Ni(C5H5)2, or a derivative of this metallocene is employed as a starting material of this impurity.  Even at room temperature or a temperature lower than room temperature a metallocene or a derivative thereof has such high vapor pressure as to per-mit the epitaxial growth of a semi-insulating film so that heating of a line for feeding an impurity into a reaction tube may be eliminated and consequently an epitaxial system may be much simplified.  Furthermore, introduction of the impurity into the reaction tube may be instantaneously started or stopped by opening or closing a stop valve inserted into the feed line so that the impurity distribution may be sharply changed from one semi-insulating epitaxially grown film to another.

Abstract: ABSTRACT OF THE DISCLOSURE            The total range to be explored consists of a suc-cession of range-steps.  For each range-step, a transmitter emits upwards at least one laser pulse, which is reflected downward by clouds onto a gated receiver.  The gating interval of the re-ceiver, relative to the emission instant, determines what range-step is being explored.  The gating interval is progressively shifted, to run through the range-steps.  For each range-step, reflected laser pulses received during the gating intervals, if any, are integrated.  Because the power attenuation of the re-flected pulses is an approximately quadratic function of height, the relationship between the range-step value and the integrated signal is made approximately quadratic.  In the lower part of the total range, this is done by progressively overlapping the conical beam patterns of transmitter and receiver, to create an overlap which increases quadratically with height.  At least in the re-maining upper part, an integration schedule is established, fixing for each range-step the number of pulses integrations performed before going onto the next range-step.  The number of integrations performed per range step increases approximately quadratically as a function of range-step value or height. The beam-overlap ex-pedient is used because of its simplicity, but is limited as to range.  The integration-scheduling expedient is not limited as to range but cannot always be devised to span the transition between lower and upper parts of the total range.  The two expedients in conjunction make it possible to span across the middle part of a large ceilometric range.
