Abstract: There is described a container for dispensing liquids in which an elongated, resilient, delivery tube is positioned within the container in a deflected and compressed condition, so that when a closure is removed from an opening in the container the upper end part of the delivery tube is urged out of the container by its own resilience. The delivery tube is then grasped and pulled outwardly until cooperating formations on the lower end of the delivery tube and the container nozzle form a seal therebetween. A flexible wall or diaphragm may be provided to expel fluid from the container. After use, the delivery tube is replaced within the container by pushing the first end part, and a cap is placed over the opening in the container.
Abstract: A rubbing compound compound concentrate suitable for dispensing as a foam from an aerosol container is made from 16 to 28 percent by weight of a soap moiety which has a soap solids of 8 to 18 percent by weight of the soap moiety, from 16 to 46 percent by weight of an adjuvant moiety of suspending agents, wetting agents, lubricants and odoring agents and from 17 to 50 percent by weight of an abrasive, preferably amorphous silica, having a maximum particle size of 55 microns and sufficient deionized water to produce a viscosity of 60 to 80 Krebs units. An aerosol composition is made from the concentrate and 5 to 10 percent by weight of a propellent sufficent to provide aerosol discharge while maintaining an in-can solids of 45 to 60 percent by weight. The process of making the concentrate comprises first forming in place the soap moiety and serially adding the adjuvants and abrasive while maintaining a penetrometer reading of 350 to 450 mm. in ASTM D217.

The anti-settling agent is present in a volume ratio to the solids of 1:10 to 1:50.
Abstract: The disclosure is directed to a method, reagents and apparatus for the rapid (one to four hours) identification of Neisseria gonorrhoeae and Neisseria meningitidis from cultures grown on a selective or a non-selective medium. One drop of growth suspended in sterile salt solution is placed in each of a plurality of miniature reaction chambers supported on a common base and incubated at 35.degree.-37.degree. C. for one to four hours. A dried substrate and buffer is contained in each chamber. A detector reagent such as a diazo dye in an aqueous solution with a polar solvent is added to each chamber after incubation. The color change in each chamber is noted and compared with a profile to identify N. gonorrhoeae and Neisseria meningitidis. Synthetic substrates rather than sugars are used in the reaction chambers. The substrates are naphthyl derivatives, .beta.-naphthyl or .beta.-naphthylamides, and are(1) .beta.-naphthyl-.beta.,D-galactopyranoside(2) N-L-.lambda.-glutamyl-.beta.
Abstract: The disclosure is directed to a novel method of forming and packaging for display hollow, solid space air treating devices. A molten treating composition is charged into the outer shell of a thermoformed container which serves as a mold, as well as a display package for the finished product. An inner core is placed inside the outer shell displacing the molten material and forming a chamber of the shape and size of the device. A gas equalizing aperture permits release of internal pressure and excess molten material. The filled mold is cooled. The sealed container is suitable for shelf display but may have additional trade dress applied, if desired. The ultimate user removes the outer shell from the solidified device to activate the space air treatment feature.
Abstract: An apparatus for individually dispensing a plurality of articles is provided comprising:(a) a case for receiving articles to be dispensed;(b) a cover slidably mounted on the case for reciprocal movement relative thereto wherein movement of the cover in the direction of dispensing an article forms an opening for removal of a single article;(c) a pushing member slidably positioned between the case and cover and cooperating with movement of the cover to advance articles to be dispensed, the pushing member flexibly engaging the case and the cover in a retainer located on the inner surface of the case and cover, the pushing member being advanced in the direction of dispensing an article at a distance equal to the displacement of an article in response to movement of the cover in that direction and immovable in response to movement of the cover in the direction opposite to dispensing an article.
Abstract: An insecticidal device of the "flypaper" type which utilizes a non-drying glue is disclosed which has the improved characteristics of concealing from sight the insects which are trapped on the glue. This is done by a plurality of opaque hoppers which are placed one above the other around a vertical support structure. The opening of each hopper is large at the top, providing access of the flying insects to the glue, and small at the bottom, to retain the insects which in time dry and fall free from the glue. An embodiment is disclosed in which provision is made to collect all of the dead insects in the bottom hopper.
Abstract: The inclusion of 1 to 15 per cent by weight of pure ethyl alcohol (190.degree. - 200.degree. proof) in lecithin-vegetable oil compositions lowers the viscosity, provides a uniform one phase system, and renders high concentrations of lecithin compositions suitable for dispensing from non-aerosol, squeeze or spray bottles. Such compositions which contain relatively higher concentrations of lecithin may be used by the consumer in proportionally lesser amounts to achieve the same anti-stick properties or basting properties associated with the presently available products containing lower lecithin concentrations.
Abstract: The disclosure is directed to a device for sealing the neck of apparatus which utilizes a wicking action to move liquid from the interior of a container to the surrounding atmosphere. The wick is disposed about an inner core of a cellulosic material which when wetted, expands to press the wick against the sides of the orifice. The wicking action is improved and the spilling of the contents through the orifice, in the event of an upset of the container, is prevented.
Abstract: The disclosure is directed to a lid latch concealed in a tamper-proof enclosure and a centrifuge interlock circuit which prevents the opening of the lid latch until the rotor has come to a full stop, and which requires electrical power to release the latch. Rotation is detected by a low level direct current applied through a sensing resistor to the brushes of the drive motor, after drive power to the motor has been cut off. Any rotation will cause rapid modulations of the current through the sensing resistor, which develop a corresponding signal voltage across the resistor. The signal voltage is amplified and applied to trigger a clamp circuit, which overrides a lid latch release device until rotary motion has ceased.
Abstract: A battery powered, hand held, light weight electrical shocking device provides a visible and audible display of sparks continuously upon the operation of a switch.
