Abstract: COMBINATION TENT AND FRAME THEREFOR      ABSTRACT OF THE INVENTION This invention relates to a novel tent construction characterized by at least two, and preferably four, identical subframes, each pair of which is connected together at the adjacent upper outside corners to produce in unfold condition an inverted generally V-shaped frame when the lower marginal edges therefor are maintained in maximum fixed-spaced relation to one another by a foldable fabric floor stretched therebetween. When four subframes are employed, the second pair is connected to the first in end-to-end relation so as to double the length of the resulting frame. Each subframe includes a unique molded hub at the center thereof having four equiangularly-spaced sockets therein shaped to receive a ball on the inner end of a springable rib-forming strut for movement between a folded position nested alongside one another and an unfolded position arching radially therefrom in umbrella-like fashion.  The fabric covering stretched over the subframe cooperates therewith to not only maintained the rib-forming struts in arched umbrella-like fashion when unfolded, but additionally, to keep the ends thereof seated in sockets in the hub and connectors thereof.  Socketed connectors adapted to detachably receive the outer ends of the upper struts of each pair of interconnected subframe for foldable movement are provided along the ridge of the tent, these connectors differing from the hub in that the webs separating the sockets are sufficiently thin and flexible to permit the sockets themselves to move between an essentially radial coplanar relationship into a non-planar one in which they approach a parallel relationship to one another.  In the embodiment where four subframe are employed, the middle connector of the three on the ridge has four sockets while those at opposite ends have only two.  Double-socketed connectors similar in construction and operation to those used at the ends of the ridge are found at the base of the frame connecting the adjacent pairs of subframes together.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to terminal modules, or modu-lar interconnect terminals for use in establishing inter-connections between parts of telecommunication systems and the like.  More particularly, it relates to unit frames or bodies of use in electrical interconnection modules.  Prior art telephone termination systems, and particularly those used in association with key telephones in business office environments, have required excessive expenditures of both time and money for installation, for maintenance and for changes in the wiring systems after they have been installed.          Accordingly, a primary object of the present invention is to provide improved and more economical terminal frames and terminal modules for use in telecommunication systems and the like.  The invention accomplishes this object by pro-viding bodies, or frames, for use in the formation of modu-lar interconnect terminals.  The bodies are formed, charac-teristically, from single pieces of material to include pockets or receptacles into which electrical contact ele-ments may be fitted.  Each body, or frame, includes regions about which it may be folded to provide a four-sided box-like structure.  Before being folded the body is equipped with electrical contact elements which it supports in such way that first terminals of the contact elements are access-ible from outside the folded structure.  A flexible printed circuit board having conductors arranged in patterns on at least one face is folded within the box-like structure and its conductors are connected to second terminals of the contact elements to provide selected interconnections be-tween the electrical contact elements.

Granted: 1981-07-21
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a process for the continuous production of nitroguanidine from quanidine nitrate by the action of aqueous sulfuric acid and possibly nitric acid reusing the concentrated sulfuric acid recovered from the previous step whereby the conversion is carried out using 2.5 to 3.5 moles per mole of guanidine nitrate.  The dehydratation is carried out using a 82-85% sulfuric acid at a temperature of 40-80°C, preferably 40-60°C in a period of 1 to 3 hours and subsequently the sulfuric acid is diluted to 25-35% by adding water or wash-acid of 0-5°C from a previous operation and the diluted 25-35% sulfuric acid recovered after separation of the precipitated nitroguanidine is concentrated for reuse.  This process is more economical and the reaction time is considerably reduced for the same yield.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides in a rectification pro-cess in which a liquid mixture of several components having dif-ferent volatilities is divided by partial condensation into a vapor phase with high concentration of the more readily volatile component and a liquid phase with low concentration of the more readily volatile component, the vapor phase being brought into intimate contact with a dephlegmate produced by partial condensa-tion in order to obtain the more readily volatile component in a form as pure as possible, the vapor formed by external heating exchanging concentration with the liquid phase of the mixture in order to strip the mixture of the more readily volatile component to the greatest extent possible the improvement in which the total heat of dephlagmation transferred from the vapor phase to a heat trough is divided into arbitrarily small amounts which are then extracted from the vapor phase so as to be distributed over the entire region of the rectification while correspondingly small amounts of dephlegmate are produced, whereby the vapor phase is passed along the dew-point curve in the enthalpy-concentration diagram and the stripping step is initiated by dividing the added heat into arbitrarily small amounts which are made available by a heat source, thus producing correspondingly small amounts of vapor locally whereby the liquid phase is passed along the boiling-point curve in the enthalpy-concentration diagram.
