Abstract: Apparatus for protecting the finish of an automobile from damage caused by opening doors of other automobiles against the automobile protected by the apparatus of the present invention. A shock cord is mounted at the most effective location on the side of an automobile by using clamping devices which are removably affixed to the lips of the front and rear wheel wells at locations which best mount the shock cord for protecting the automobile. The clamping device includes a cord holder which is both rotatable and slidable with respect to a clamping portion of the device in order to allow clamping at all locations on the wheel wells with a generally horizontal shock chord.

Abstract: A flexible container for the storage of liquids which incorporates a resealable opening. A flap is temporarily sealed over the opening of the unfilled flexible container. When the container is filled this temporary seal is broken and after filling a permanent heat seal is formed by applying heat externally to the flexible container. The flap is heat sealable on the surface contacting the opening in the container wall but non-heat-sealable on its opposite surface. The temporary seal is preferably a heat activated or pressure sensitive coating which has a low cohesion with the opening of the flexible container wall.

Abstract: A flow meter apparatus for measuring the mass flow rates of fluids passed through a cantilever mounted oscillating sensing tube where the capability of the meter to measure low mass flow rates is enhanced by using a sensing tube which has a low torsional spring constant about its longitudinal axis. Mounted parallel to this sensing tube, also in a cantilever fashion, is a second tube which has essentially identical moments of inertia and spring constants. Connecting the two tubes at their free ends is a lightweight rigid structure. The two tubes with the connecting structure can be sinusoidally driven so that when a fluid is passed through the sensing tube generated Coriolis forces torsionally deflect the connecting structure about an axis located midway between the tubes.

Abstract: Apparatus and method for making fluid mass flow rate measurements using a Coriolis flow meter equipped with sensors which measure acceleration, velocity, or position of each side leg of an oscillating U-shaped conduit through which the fluid is passed. The sensors are so constructed and located as to produce analog signal outputs which accurately correspond to the motion of the respective side legs of the U-shaped conduit. When fluid is flowing through the conduit, a change from coincidence in the time relationship of the sensor signals caused by the divergent oscillations of each side leg of the U-shaped conduit is measured in both directions of oscillation. The fluid mass flow rate is then determined as a function of such time separation of the signals. The separation of the two signals with respect to time is measured without reference to static structures affixed to a platform.

Abstract: A holder (10) for photographic slides which is normally in a rectilinear condition in which it can be contained in a box. The holder includes a flexible element (12) which has connecting portions (18, 20) at each end thereof. A tongue (28) associated with the portion (18) co-operates with a tongue associated with the portion (20) and the portion (18) co-operates with a flange (34) to secure the holder into the form of a closed loop. A unit (14) is attached to the element (12) and to the portions (18, 20) and forms a series of pockets (54) each of which serves to receive a photographic slide. From the holder (10) the slides are transferred directly to the pockets of a slide magazine for projection. The holder (10), when straight, occupies less space that a rotary projector magazine and is far less expensive to produce.

Abstract: An article printing system is disclosed wherein successive strips of closely-spaced interconnected articles, such as electronic components, are fed in an intermittent manner by an endless conveyor belt to a printing nip located beneath a continuously rotating offset roll which is arranged for synchronized vertical reciprocation. Belt perforations corresponding in location to each individual article to be printed are sensed by a photoelectric detector to stop the article at a ready position located a predetermined distance from the printing nip. When a printed image on the offset roll rotates to a position of predicted registration with the motionless article surface below, the belt is restarted and the offset roll is lowered to its printing position in order to transfer the image to the article as it traverses the printing nip.

Abstract: A method is disclosed for quantitative measurement of angiotensin converting enzyme activity in biological material. The method exploits certain acylated tripeptide substrates. The enzyme-catalyzed hydrolysis of the substrates results in the formation of a dipeptide reaction product and a remnant product. The substrate is radioactively labeled exclusively in that portion destined to become the remnant product. Preferably, the substrate prior to hydrolysis is essentially insoluble in an aprotic organic solvent, but the remnant hydrolysis product is essentially quantitatively extractible by the organic solvent. At the termination of the enzyme-catalyzed hydrolysis, the labeled remnant product is separated from the reaction mixture, and the radioactivity is counted in a suitable apparatus.

Abstract: Dental restorative compositions of improved X-ray opacity are described. These compositions comprise from 30% to 85% by weight of the composition of a finely divided inorganic filler and from 15% to 70% by weight of the composition of a liquid resin binder. The filler comprises at least 60% by weight of the filler of a ground barium glass that has a barium oxide (BaO) content greater than about 22.5% by weight of the glass. By appropriate selection of the binder, the composition may cure in a single stage of curing, or it may set in two stages, to provide a period of time during which it can be carved to a desired shape.

Abstract: Discloses a technique for modifying an epoxy resin by reacting with addition copolymerizable monomer in the presence of at least 3% of benzoyl peroxide at about 110.degree. C. to 120.degree. C., or the free radical initiating equivalent thereof. The reaction mixture obtained contains:(a) unreacted epoxy resin;(b) graft polymer; and(c) associatively formed but ungrafted addition polymer.The graft polymer is formed from the epoxy resin by the grafting of addition polymer onto aliphatic backbone carbons of the epoxy resin, such grafting being at carbons that have either one or two hydrogens bonded thereto in the ungrafted state. The process is useful for making polymer blends for coating compositions, and particularly, coatings for cans for foods and beverages, especially for beer. The coating compositions may be aqueous dispersions ready for spray application, or concentrate that can be made up readily into aqueous sprayable coating compositions. Solvent vehicles may also be used.

Abstract: A test for determining the sulfur content of the base cast iron used for the production of nodular iron or iron containing compacted graphite. A sample of the molten base cast iron is removed from the melt, then a known amount of a nodular iron inoculant or a compacted iron inoculant is added to the molten metal. The molten metal sample is then cast into test bar or test wedge, solidified and tested to determine whether the bar or wedge is nodular iron or iron containing compacted graphite. The test may be fractured and inspected to visually determine whether the fracture is gray or white. Alternatively, the wedge or bar may be ultrasonically tested to determine whether the wedge or bar contains flake graphite or nodular graphite or compacted graphite. As a further alternative, the cooling or solidification curve of the molten metal sample, after inoculation, can be determined and compared with the cooling curve from a molten base cast iron sample.
