Abstract: A door stay device for automatically locking a door in an open position includes a first component adapted to be attached to a stationary support, the first component including a plate having a curved cam edge with a radius matched to a swinging movement of the door between closed and open positions. The plate has a slot open at the cam edge at a location corresponding to the open position of the door. A second component is adapted to be secured at a lower or upper edge of a door, the second component having a locking member arranged to move into the slot when the locking member is aligned with the slot and the door is in the open position.

Abstract: In managing the backlog of undelivered publications for durable subscriptions, a maximum quantity of publications stored in connection with a durable subscription to publications of a particular topic can be established on behalf of a particular subscribing end user. A new publication published for the particular topic subscribed to by the end user can be received and it can be determined if storing the new publication in connection with the durable subscription causes a quantity of publications stored in connection with the durable subscription to exceed the maximum quantity. The new publication can be stored in connection with the durable subscription; however, the oldest publication stored in connection with the durable subscription can be removed when it is determined that storing the new publication in connection with the durable subscription causes a quantity of publications stored in connection with the durable subscription to exceed the maximum quantity.

Abstract: In one embodiment, an iceboard includes a plank having a first end and a second end and a first side and a second side. One or more supports are coupled to the first side of the plank and, one or more blades are coupled to the one or more supports, the blades operable to glide across an icy surface. The iceboard further includes a piece of frictional material coupled to the second side of the plank and operable to provide traction relative to the plank. The iceboard further includes a brake coupled to the first side of the plank adjacent a first end of the plank. In particular embodiments, the brake is operable to abrasively scrape the icy surface when applied to the icy surface.

Abstract: A musical instrument pick holder that provides convenient temporary storage of one or more picks. The pick holder provides a housing that is the same or substantially the same shape as the pick. The pick holder stores one or more picks therein and provides for quick and easy access to the picks. The pick holder has an internal biasing member that releasably retains the picks therein. The pick holder further provides one or more exterior surfaces that are suitable for placement of advertising or marketing indicia or graphical elements. The pick holder further comprises a key ring or other clasping element for releasable coupling with another items such as the garment of a musician.

Abstract: In order to test whether a diamond has had a layer of synthetic diamond deposited thereon, it is irradiated with high energy ultraviolet radiation to cause emission of luminescence, the luminescence intensity produced by different zones of the diamond being measured and compared. In one embodiment an integrating enclosure (15) is used and the diamond (13) is mounted on a rotatable mount (14).

Abstract: In order to test whether a diamond has had a layer of synthetic diamond material deposited thereon, infrared radiation including radiation of wavelength substantially 7 .mu.m to 25 .mu.m preferably 7 .mu.m to 10 .mu.m emitted or transmitted by the diamond is observed, to detect differences between the compositions of different zones of the diamond.

Abstract: In order to test whether a diamond has had a layer of synthetic diamond deposited thereon, the surface area of the natural part of the stone is measured by measuring the radiant-flux density of radiation substantially of wavelength 230 nm to 320 nm in an integrating sphere containing the diamond. This is compared to the total surface area of the diamond.

Abstract: In order to examine a gemstone, the stone is irradiated and observed though a filter (5) at a first wavelength which is characteristic of a first class of gemstones. The filter can be rocked from a setting normal to the optical axis to transmit radiation of at least one reference wavelength. The intensities of radiation transmitted at first and reference wavelengths are observed and compared, to classify the gemstone as belonging to the first class or not. In order to detect whether the gemstone is a diamond or diamond simulant, the first wavelength comprises raman emission characteristic of diamond. In order to detect whether the gemstone is definitely natural or not definitely natural, the gemstone is classified as definitely natural if there is a maximum of absorption of radiation at 415.5 nm.

Abstract: In order to test whether a diamond 2 comprises synthetic diamond material, a plurality of different zones of the diamond 2 are irradiated with radiation substantially of wavelength substantially 230 nm to 320 nm, an image or reading of the radiation transmitted by each zone of the diamond 2 being produced.
