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 novel purification scheme is described for obtaining two novel and useful forms of bovine glycoprotein (BGP) from bovine erythrocytes, each of which acts as an antigen in testing for the presence of the heterophile antibodies of human infectious mononucleosis.The first, or partially purified, BGP is obtained from crude BGP and contains about 10% by weight of a complex glycoplipid. It forms a single band upon gel electrophoresis at pH 7.0 under specified conditions.The second, or homogeneous, BGP is obtained by removing essentially all of the complex glycolipid. It forms substantially a single band upon gel electrophoresis at pH 7.0 under specified conditions.Both forms may be used to detect or quantify hemagglutination inhibition of a test sample (and hence to determine the presence or extent to mononucleosis infection) in a glass slide test wherein the partially purified or homogeneous BGP is carried on latex or synthetic resin beads.

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: A process is provided which permits the rapid concentration and collection of cells in body fluid with minimal need for centrifugation and without filtration or sediment flotation, while also permitting the collection of cells from the fluid in an essentially monolayer arrangement with essentially no cell distortion. The apparatus used in this process comprises an elongated receptacle or chamber having, at one end, an outlet opening through which body fluid containing cells to be collected can be introduced, e.g., by means of a syringe, and, interposed between the inlet opening and an outlet opening at the other end of the chamber, a filter, e.g., a microporous filter.

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: A fuel consumption signalling system for signalling both efficient and inefficient fuel consumption conditions in the engine of a motor vehicle is herein disclosed. The system comprises an alarm circuit connected in series with an indicator circuit including an indicator light connected in parallel with a vacuum operated switch pneumatically connected to the engine manifold. An electric potential sufficient to actuate the alarm circuit, but insufficient to actuate both the indicator light and the alarm circuit is applied across the series connected indicator and alarm circuits. When the engine is consuming fuel efficiently, the vacuum switch is open, and the electric potential is divided between the indicator circuit and the alarm circuit. The divided potential is sufficient to illuminate the indicator light, but insufficient to actuate the alarm circuit.
