Abstract: An in-line heater for an aerosol delivery system has an elongated tubular electrically insulated plastic body having first and second ends coaxially aligned along the major axis of the tubular body. The first and second ends contain an aerosol inlet and outlet, respectively. The plastic body has an unrestricted flow passage therein from the first to the second end and a self supporting electrically conductive spiral mesh heating element loosely fills the flow passageway within the body. The mesh heating element has a very low mass so as to be almost instantaneously responsive and extends across the space between the side walls of the flow passage to maximize the surface area thereof exposed to the aerosol mixture flowing through the passage. First and second terminals are adjacent the first and second housing ends, respectively, and are connected to the ends of the spiral mesh heating elements by a pair of crimped connector plates.

Abstract: A tamper-evident container closure and container assembly with tamper-evident ring which breaks away from the cap as the cap is unscrewed. The cap includes a pawled ring with a plurality of breakable connectors and connection of the pawl tips to the cap providing coupling of the ring to the cap. During assembly, the pawls ride over ratchet teeth on the container breaking the pawl connections to the container. When the cap is removed, the pawls interlock with the ratchet teeth breaking the breakable connectors. The ratchet teeth may be arranged in two sets of teeth offset from one another to provide reduced back-off and reduced back-off torque.

Abstract: A contact lens disinfecting unit in which the lenses are immersed in a saline solution and heated to a predetermined minimum disinfecting temperature which is maintained for a predetermined period of time. The unit has a heating system which includes a PTC thermistor as a heating element sandwiched between metal heat distribution plates, and this heating system interacts with a manually resettable thermostat to control operation of the unit.

Abstract: A linerless closure for use in sealing plastic bottles and jars is disclosed. The linerless closure has a series of concentric annular sealing rings for sealing contact with a bottle mouth. A ridge located between an inner and outer sealing flange provides for a minimum of two sealing surfaces and a maximum of three sealing surfaces with a bottle mouth. A buttress flange spaced inwardly of the inner sealing flange provides additional strength to the inner sealing flange for guiding an irregular bottle mouth to a sealing engagement.

Abstract: An explosive blasting method and apparatus for producing rock fragmentation and substantially reducing the amplitude of seismic effects (ground vibration) in the vicinity of the blast. An embodiment of the invention utilizes an air gap method and apparatus for superheating the air surrounding the charge in a borehole thereby significantly raising the pressure therein coupled with the use of multiple detonation points along the borehole for the reduction of burn time thereby substantially reducing the quantity of explosives used along with a marked reduction of seismic shock, sound and dust effects to the surrounding area.

Abstract: This invention relates to a process for automatically measuring the Brinell Hardness of a casting for the purpose of creating data for use in making an accept/reject decision. Process includes the steps of preparing a casting and positioning the casting on retention means positioned on a conveyor. A surface of the casting is selected for testing and this first surface is subjected to a first surface preparation step which consists of an abrasive grinding and/or machining to remove any irregularities in this surface. A second surface preparation step is then performed which comprises applying a contrast enhancing material to at least a portion of this preselected surface. Brinell Hardness testing apparatus is then used to test the casting for hardness and is then fed into appropriate means either human or mechanical for making an accept/reject decision as to the suitability of the casting for its intended use.

Abstract: A method and apparatus is described for feeding grid stock through a punch and die arrangement so that the spaced apart slots are equally spaced during the progression of the grid stock. The feed mechanism for strip stock comprises reciprocating punch means, die means associated with said reciprocating punch means to cooperate to punch out a group of spaced-apart slots in said strip stock, supporting means associated with said punch and die means to support said strip stock during its advance, a pair of members slidably mounted to said supporting means to operate on adjacent groups of spaced-apart slots in said strip stock to positively feed said stock away from said punch and die means, and means timed in respect to the reciprocation of said punch and die means and operative thereby, while said die means is raised from said punch means, to impart feeding movements to said feed stock.

Abstract: A gyroscopic device of the type having a short-circuited rotor winding or conductor so shaped so as to produce axial and radial flux components when rotated in the earth's magnetic field is coupled to a coaxial sensing coil coaxial which gyroscopically stabilized thereby, signals induced in the sensing coil due to the axial flux component of the rotor is used to derive magnetic heading information and there is provided at least one further coil on the supporting body and inductively linked to the sensing coil and rotor such that when the sensing coil is gyroscopically stabilized by the rotor, the coil supported on the supporting body in relation to the gyroscopically stabilized sensing coil is such that any changes in angular orientation of the supporting body relative to the gyroscopically stabilized sensing coil introduces changes in the signal voltages induced in the coils.

Abstract: Toluene and toluene derivatives are dehydrocoupled to stilbene and stilbene derivatives in a vapor phase reaction in the presence of a metal oxide. The stilbene products are purified of by-product polar impurities. The purified stilbene can be catalytically reacted in the vapor phase with ethylene to produce styrene.

Abstract: Process for receovering copper values (and zinc, if present) from copper bearing materials, optionally in admixture with iron. The feed material is leached with a mixture of nitric and sulphuric acids, after which the dissolved copper is cemented from solution by contact with iron. The solution, containing dissolved iron (and zinc, if present in the feed material) salts is reacted with ZnO to precipitate iron as ferric oxide, which is separated, leaving zinc sulfate in solution. Solid zinc sulfate is recovered from the solution by evaporation, and then calcined to produce SO.sub.2, which is recovered and recycled as H.sub.2 SO.sub.4, and ZnO, which is reused in the process, any excess being recovered as a product.
