Title: Method and apparatus for automatically testing a railroad interlocking
Inventor: WINKLER JOSEPH C
IPC: G01M99/00
Filed: 2005-07-07
Abstract: A railroad signal system interlocking is automatically tested. A control point interface corresponding to a predetermined function of the interlocking has an isolated section and a control section. The isolated section is connected with the interlocking and has a normal, inactivated state during operation of the interlocking, and an activated state for testing the interlocking by detecting an electrical characteristic representing the status of the predetermined function executed by the interlocking.

Title: Gasoline-impermeable coatings
Inventor: ULCAR JOHN
IPC: C08J7/048
Filed: 2005-10-04
Abstract: A coating that can be adhered to a polyethylene gasoline container to substantially reduce its gas permeability, and a gasoline container treated with such a coating. A single-component cationic curing composition with increased impermeability to gasoline vapour uses a bis 'F' epoxy in combination with a catalyst and oxetane. The invention takes advantage of a narrower ultraviolet absorption spectrum of the bis 'F' epoxy, whereby ultraviolet radiation outside the UV  absorption spectrum of the bis ',F' will activate the catalyst, the highly active superacid from the antimonate anion, without any significant reduction of the cationic curing reaction. In the preferred embodiment the bis 'F' and oxetane combination is used along with various additives included for flow and cosmetic purposes.

Abstract: A brewing and drinking receptacle comprises an outer cup (2), an inner cup (3) nested within the outer cup and turnable relatively thereto, and an ingredient chamber (13) formed between mutually opposed bottom walls (4, 5) of the nested cups. A brewing aperture (14) which may be a perforated section, is formed in the bottom wall (5) of the inner cup and communicates with the ingredient chamber. A shut-off boss (15) projecting upwardly from the bottom wall (4) of the outer cup within the ingredient chamber is arranged to control liquid flow through the brewing aperture. The outer and inner cups (2, 3) are turnable relatively to one another selectively to admit or shut off flow of water, which is added to the inner cup to produce the beverage, between the inner cup and the ingredient chamber (13), via the brewing aperture. This enables the water to be mixed or infused with the ingredient in a controlled fashion and for the flow of beverage between the ingredient chamber and the inner cup to be shut off when the beverage achieves the desired strength. A paddle member (24) projects into the ingredient chamber from the bottom wall (5) of the inner cup so as to squeeze and/or agitate the ingredient in the ingredient chamber (13) in response to relative turning movement of the cups and thereby enhance mixing or infusion.
