Abstract: A method and apparatus are disclosed for treating a textile article which has raised embroidery on its front side. A plastic sheet is laminated to the back side of the textile article by the application of heat and pressure. Moisture is applied to the front side of the article so that the embroidery which may have been flattened by the lamination process is returned to its original raised condition.

Abstract: This invention relates to melt extruded latent contractable elastic filaments which are formed by melt extruding certain segmented crosslinked thermoplastic polymers to form filaments, which filaments, when heat processed at elevated temperatures, significantly contract to yield an elastic filament. This invention also relates to the formation of composite covered yarn comprising said latent contractable melt extruded filaments. In addition, this invention relates to processes for forming articles from said latent contractable filaments or covered yarns comprising said contractable filaments and subsequently contracting said yarns to form an elastic article.

Abstract: An improved split body clamping or pressure containment device is provided where the body members are retained together through the use of a plurality of double ended links. The ends of each of the links are juxtaposed to and associated respectively with each of the clamping body members. Rotary cams mounted on shafts which pass through the ends of the links compress the body members together and cause other movements of one of the body members and the links.

Abstract: A process for making particulate substantially water-insoluble magnesium phosphate product and method of use of the product for removing ammonia from aqueous solutions. The particulate magnesium phosphate product acts as a remarkably effective scavenger wherein under equilibrium conditions only about six (6) grams of the product are required to bind the ammonia (more exactly, ammonium ions) liberated from one (1) gram of the urea, a result far superior to traditional zirconium phosphate (ZP) prior art materials which under ideal conditions require about 17 to 20 grams of ZP per gram of urea. The particulate magnesium phosphate product can also be used for the removal of ammonium ions either produced by enzymatic or non-enzymatic hydrolysis of urea or proteins or amino acids or available as NH.sub.4.sup.+ from its native source. The magnesium phosphate product is made by forming a slurry of water and magnesium hydroxide in the presence of a phosphate ion-containing buffer having a pH of about 6.5 to about 8.

Abstract: An improved insulation piercing contact for use in an electrical connector is provided. The contact is made of a sheet metal stamping, which includes a top portion for making electrical contact with a first conductor, and a bottom portion which includes at least two tines. Each tine is bevelled and has a bottom edge which pierces the insulation of a second conductor and makes contact. The tines may project away from one of the planar surfaces of the contact.

Abstract: A novel method for dilating cold shrink articles such as insulating tubing is disclosed. The method makes use of a two phase bath comprising two immiscible liquids in which the lower phase is a swelling agent for the cold shrink material and the upper phase serves as a protective blanket which eliminates the generation of fumes by the swelling agent.

Abstract: There is provided a dual in-line socket assembly including an insulator block having a plurality of primary holes therein, each hole receiving an electrical socket. The sockets are adapted to receive pins from integrated circuit chips. At least one of the primary holes has a secondary hole or slot drilled adjacent and contiguous thereto for receiving an electrical lead. The electrical lead is connected to a circuit element and the lead forms an interference fit with a corresponding adjacent socket.

Abstract: There is provided an improved sanitary napkin which utilizes a sheet metal substrate. The sheet metal substrate acts as a barrier to liquid flow. However, it includes a plurality of embossments having small holes therein which permit the sanitary napkin to breathe while also serving as a heat sink. The sanitary napkin also includes fluid absorbent layers overlying the sheet metal substrate.

Abstract: There is provided a plastic collar integral with the outer jacket of a cable. The plastic material includes a mixture of a plastic and an electrically conductive material such as carbon black. The plastic is melt bonded to the cable jacket by applying electric current through the material, thus melting the material onto the jacket of the cable. Upon melting, the semi-conductive plastic may be molded into the desired form, and upon cooling, it becomes bonded to the cable jacket. The collar may be used as a seal for the ends of a cable splice closure as well as a shoulder for securing a sealing gasket to a cable for use in such closures. The collar also may be used as strain-relief for the conductors which are inside the cable as well as other uses.

Abstract: An improved electrical socket for providing superior electrical and mechanical contact to a mating electrical pin. The socket includes an elongated metallic box which receives the pin contact. An elliptical spring is secured in the box by ear pairs projecting from the opposing ends of the elliptical spring. A pair of cantilevered beams, integral with the top of the box, are bent slightly downward and have their free ends in contact with the ends of the elliptical spring. The cantilevered beams thus form a pair of single leaf springs. The elliptical spring and the cantilevered beams cooperate with each other to provide a suitable force on the inserted pin over a wide range of deflections of the springs.

Abstract: There is provided a telephone toll restrictor which is adapted to split the telephone line into two separate circuits for isolating the instrument from the central office during dialing. A dialing tone sensor provides signalling information to a programmed microprocessor which determines whether or not the number is permissible. A pair of filters separate the high and low frequencies of the tone and input this information to the microprocessor. If the dialing tones are permissible, then a generator regenerates the tones and passes the tones to the central office for completing the call. Furthermore, the telephone line is then recoupled and the call is permitted. If the call is not permitted, then a holding bridge, which holds the central office while the microprocessor examines the number, is opened by the microprocessor, causing the central office to time out, thus denying access to the caller.

Abstract: A method and apparatus for containing an annular body of fluid about a sleeve spanning the abutting ends of pipe lengths, and firing a charge of propellant, such as fast burning smokeless powder, in the liquid so as to radially shrink the sleeve into sealing engagement with the pipe lengths. If desired, the pipe lengths can be internally supported to avoid the possibility of collapse. Hard annular elements may be interposed between the sleeve and the pipe length ends to produce better mechanical locking.

Abstract: There is provided a building structure made from wooden logs with gaps between the logs for receiving insulation. The gaps are formed between the stacked logs by driving sharpened spikes into oppositely facing logs so that the opposing sharpened tips of the spikes penetrate the logs and secure a fixed distance between such logs. Two spikes are normally aligned with one another and respectively driven near the inner and outer walls of the log structure. Each spike has a hole drilled there through for receiving a screw-like rod interconnecting the two spikes and supporting various building items such as a wire mesh screen for receiving plaster, a vapor barrier and inside panels. Furthermore, insulation is provided between the two logs so that the thermal resistance of the overall building structure is greater than a building structure which would use logs alone.

Abstract: There is provided an electrical cable splice assembly, including a splice case having two ports for receiving a pair of cable ends. The conductors within the cable are adapted to be spliced together inside the splice closure. A pair of cable clamping devices are each firmly attached to each cable a certain distance removed from the splice closure. A rigid member, having a pair of rigid arms, attaches the cable clamping devices directly to one another so that any strain applied on one cable is transferred to the other and the splices within the splice closure do not feel the effects of the strain. There is further provided a clamping ring attached to the assembly for receiving a rod to be buried in the ground such that the height of the assembly with respect to the ground can be varied during installation.
