Abstract: ABSTRACT       An oil seal unit for disposition between portions of mating parts having opposed end face sealing surfaces and which are urged together in fluid-tight relation, one of said mating parts also having a shank portion adapted to extend axially through an associated seal unit.  The oil seal unit comprises, in combination, a casing unit having an axially extending centering flange portion and a radially extending bonding flange portion with opposed end face surfaces and an inner margin portion, and an elastomeric, seal body bonded to said casing unit.  The body has radially inner, outer and intermediate seal body portions, the outer elastomeric seal body portion including at least one substantially continuous sealing rib overlying one of the casing end face surfaces and at least one substantially continuous rib overlying the other of the casing end face surfaces.  The radially inner portion of the said elastomeric seal body includes a radially extending web terminating in a radially inner, axially extending web surface portion defining an opening through which the shank portion of the one mating part may extend, the web also engaging the shank portion of the one mating part so as to support the seal relative to the one mating part.  The intermediate seal body portion includes an element adapted to be deformed into snug fluid-tight sealing engagement within a recess defined in part by the seal unit and in part by the opposed end face sealing surfaces.

Abstract: Wet laminating adhesive capable of withstanding the stresses encountered during heat sealing operations are prepared from emulsion copolymers consisting essentially of 45 to 80% by weight of a vinyl ester of an alkanoic acid, having 1 to 13 carbonatoms, 10 to 30% ethylene, 5 to 30% of a dialkyl (c4 - c8) maleate, 0.5 to 2% of an N-methylol containing comonomer, 0.5 to 4% of an ethylenically unsaturated mono- or di-carboxylic acid, 0.2 to 3% of a stablizer and 0 to 1% of a polyunsaturates copolymerizable monomer. These specific emulsion copolymers are prepared utilizing standard aqueous emulsion polymerization procedures with hydroxyethylcellulose or polyvinyl alcohol as a protective colloid. The emulsion polymers thus produced provide superior wet laminating adhesive properties for use in substrates which are to be formed into microwavable packages or bags.

Abstract: Low viscosity polymer polyol having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy resin-modified polyols as the base polyol. The styrene/acrylo-nitrile ratio may be as high as 95/5 and even 100/0 in the polymer polyols. The epoxy resin-modified polyols useful as base polyols may be made by reacting a polyol initiator having an active hydrogen functionality of 3 to 8 and one or more alkylene oxides with an epoxy resin. It is preferred that only a small part of the epoxy resin-modified base polyol be initially charged to the reactor, and that the balance, a relatively larger part, be a part of the monomer feed stream to the reactor.

Abstract: An expansion band having a spanning member whose free end is provided with a locking tab for cooperation with a locking surface having a plurality of selectable locking slots. A guide channel secured to the band cooperates with the band to define a guideway through which the spanning member extends thereby maintaining the spanning member and hence the free ends of the expansion band in alignment.  During expansion of the expansion band the locking tab is free to snap out of each locking slot and into the next.  Upon release of the expansion forces, however, the locking tab is prevented from snapping out of the locking slot in which it is presently inserted.  A novel expansion unit comprised of a manual hydraulic pump operates a duck-bill type spreader which bears against associated bearing surfaces respectively provided on one end of the spanning member and one end of the guide channel to apply direct expansion forces to the expansion band.  The locking tab and locking slots are shielded from the gasket expanded by the expansion band to protect the gasket from being scored and/or damaged.

Abstract: VOICE BRIDGE FOR A RELAY CENTER                      Abstract of the Disclosure A relay center has a first telephone line (12) and a second telephone line (14).  Data signals may be carried on the first telephone line (12) and received into a modem (20).  A terminal or computer (22) then receives the data signals and converts the signals into readable characters viewable on a display (26).  An operator then reads messages formed by the characters and voices them into a telephone (28) connected to the second telephone (14). The operator may also receive spoken words through the telephone (28) and transcribe via a keyboard (24) for transmission of data signals by the modem (20) and carried on the first telephone line (12).  Upon a command received through the first telephone line (12) or made by the operator, a voice bridge (10) may be established which establishes a direct vocal link from either the first telephone line (10) to the second telephone line (12) or from the second telephone line (12) to the first telephone line (14).  A second command disconnects the telephone (28) from the second telephone line (14) to prevent the operator from hearing the audio  sounds carried by the voice bridge (10).

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to heat insulating elements which may be connected with similar elements in a string to form a heat insulator used as a screen for limiting heat losses from heated material, e.g. bars and slabs in rolling mills.  Such screens are provided for example in the form of strings of such heat insulating elements composed of metal shells containing insulating material.  These screens may form curtains and/or covets for the hot material.  Containing chambers for the hot material may be provided with such strings of elements and the chambers may also comprise means for limiting heat conduction losses through the material supports therein. The screens may be collapsed over the ho. material thereby completely surrounding and insulating the material from loss of heat.  A displaceable chamber installation is also described for limiting heat loss when holding and transferring hot material between processing stages.

Abstract: A method and apparatus for radiographic techniques using an x-ray source (13). The radiographed object (M) is subjected to a beam (X) of radiation which is employed for forming a radiographic image of the object (M) onto a film (25). Between the radiographed object (M) and the film (25) is utilized a grid assembly (20) that prevents the disturbing effect of backscattered radiation or secondary radiation generated in the radiographed object on the radiographed image. The grid assembly (20) comprises a grid plate (22) having several equidistantly spaced lamellas opaque to x-rays. The x-rays can pass in the direction of the beam axis between the spaces (24) of said lamellas to the film (25). The grid plate is reciprocatingly oscillated at a varying amplitude so that the stops and changes of travel direction (K1...K5) are appropriately evenly distributed over the interlamellar spaces of the grid plate (22), thereby avoiding the imaging the grid lamellas (23) in a disturbing manner onto the film (25) or other imaging means. <IMAGE>

Abstract: A low profile remotely controlled carriage which is inserted between the rotor and stator of an electric generator carries an impactor which can be preloaded to strike the stator wedges in all orientations around the stator with a selected high impact force which causes the stator wedge to vibrate. A detector seismically isolated from the impactor measures the deflections in the vibrating stator wedge. Preferably, the detector includes an eddy current coil positioned to measure the distance to a wedge follower which vibrates with the wedge. In one embodiment, the wedge follower is a vacuum cup secured to the wedge. In another, the eddy current coil measures the distance to a foot spring biased against the vibrating wedge. Preferably, the detector is seismically isolated by mounting it on a separate carriage disposed in an aperture in the low profile carriage.
