Title: Container with twist-off tamper evident feature
Inventor: HOLOUBEK GEORGE H
IPC: B65D51/22
Filed: 1986-08-22
Granted: 1991-07-02
Abstract: Abstract An integral seal member is formed across the outlet in the neck of a tamper evident, thermoplastic container by adding to the thermoplastic material such as polyethylene, 3% to 16%,  and preferably about 8% by weight,  of an anhydrous solid  inorganic  particulate  additive  such  as  an  anhydrous siliceous material or calcium carbonate so that the material becomes brittle enough that the seal member tears cleanly from the neck within the confines of an undercut at the interface between the seal member and neck. Torque is applied to the seal member by providing in the top of a conventional  screw cap which forms a resealing closure for the container once opened, a recess with serrations which, when the cap is removed and turned upside down, engage serrations on the peripheral edge of the seal.

Title: Zoned hot water distribution system for counterflow towers
Inventor: CROPP KENTON A
IPC: F28F27/00
Filed: 1987-10-23
Granted: 1991-07-30
Abstract: Abstract of the Invention A distribution system for a water cooling tower  directs  incoming  hot  water  to  particular regions of a fill assembly which are determined by the magnitude of the hot water flow rate, and struc-ture is provided for maintaining an equal head of water above all of the nozzles in current operation. During periods of relatively low flows, a weir member mounted within a distribution box of the system directs all of the incoming hot water to an outer distribution zone which is located over four outer regions of the fill assembly.   Once the hot water flow rate is increased above a certain, pre-determined value, a portion of the water spills over the weir and is conveyed to an inner distribution zone located over a central region of the Eill structure while the remaining portion of the water is directed toward the outer zone so that water is directed to the entire horizontal area of the fill structure.   Variations in the hot water flow rate either above or below the aforementioned, predeter-mined value function to raise or lower the pressure encountered by the nozzles, but the configuration of the weir member, distribution box and distribution conduits ensures that all of the nozzles in current operation continuously encounter an equal head of water without the use of valves, gates or the like.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for applying a layer of air-placed concrete to a surface in which a pumpable and sprayable air-placed con-crete mix is prepared from cement, aggregates, optionally addi-tives and water.  A predetermined volume stream of the air-placed concrete mix is delivered by a concrete delivery pump through a concrete delivery pipe to an air-placing unit comprising means for introducing propelling air under a delivery pressure of sev-eral bar.  The propelling air is charged with synthetic silica having a BET surface of at least 25 m3/g.  The synthetic silica is introduced with the propelling air into the volume stream of the air-placed concrete mix in such a quantity that, immediately after application, the air-placed concrete applied undergoes a spontaneous increase in temperature of a few degrees Kelvin.  An air-placing unit for carrying out the process is also described.

Abstract: ABSTRACT    A glass or ceramic plate (10), which may be a foamed glass or ceramic plate, is reinforced by incorporating therein a thin reinforcement layer (14) in which fibrous or flaky pieces (16) of an inorganic heat-resistant reinforcing material such as, e.g., steel wire pieces 3 to 50 mm in length are scattered so as to be two-dimensionally randomly  oriented.  The reinforcement layer (16) is parallel to two opposite major surfaces (10a, 10b) of the plate, and this layer (14) is either a buried layer or a surface layer.  The plate may have a plurality of reinforcement layers which are distant from each other.  In any case the reinforcing material (16) exists only in the reinforcement layer(s) (14).  The glass or ceramic plate (10) can be produced by the steps of layering  a particulate material of the glass or ceramic on a conveyor belt made of a heat-resistant material, scattering fibrous or flaky pieces of a reinforcing material on the surface of the layer of the particulate material, overlaying that surface with the particulate material if need be, and firing the material on the conveyor belt in a furnace.

Inventor: CHEN MICHAEL S
IPC: C07C7/04
Filed: 1988-11-18
Granted: 1992-06-09
Abstract: ABSTRACT   The present invention is an improved process for separating alcohols from ethers and/or hydrocarbon raffinate in an etherification process.  The excess alcohol reactant which forms azeotrope mixtures with the product ethers and C4-C7 raffinate, is removed by passing the liquid azeotrope mixture over a pervaporation membrane which effectively breaks the azeotrope and permeates the alcohol with high flux and high selectivity.  In a typical etherification process, one or more pervaporation membrane units can be located ahead of the ether/raffinate distillation step, in conjunction with the distillation step with a liquid side draw, after the distillation step, or a combination of any of the above.  The present invention also provides an improved process for separating alcohols from ethers and/or hydrocarbon raffinate in an ether decomposition process for the production of high purity iso-alkene products.  In this embodiment, one or more pervaporation membranes are used to recover alcohols from the decomposition product stream.
