Title: Pantagraph-type jack, and process for producing the same
Inventor: KIKUCHI NORIYUKI
IPC: B66F3/12
Filed: 2000-01-12
Abstract: A pantagraph-type jack includes a pair of lower arms and a pair of upper arms. Upper ends of the lower arms and lower ends of the upper arms are connected to each other through first and second connecting shafts. An externally threaded rod is rotatably but axially non-movably supported on the first connecting shaft and threadedly engaged with a threaded bore provided in the second connecting shaft. In the pantagraph-type jack, the externally threaded rod is formed into a hollow shape, and external threads of the externally threaded rod are provided with a tapered portion formed in a convergent shape over a given light-loaded area from a tip end on the side of the second connecting shaft. Thus, a reduction in weight of the externally threaded rod can be provided, and the threaded engagement of the externally threaded rod with the threaded bore in the second connecting shaft can be conducted easily, which contributes to a reduction in weight and an enhancement in assemblability.

Abstract: An optical fiber pumping apparatus for use with a double-cladding fiber in an optical amplifier or laser configuration comprises a plurality of laser diodes used as pump sources disposed in a spatial configuration for radiating pump energy along an optical axis through a surrounding generally annular area, leaving an available middle area. The apparatus further comprises an optical coupling device having an optical input portion generally aligned with the optical axis to collect the pump energy and having an optical output portion aligned with the pumping input portion for transferring the pump energy to the inner cladding surrounding the doped core of the fiber. The apparatus exhibits high pump power rating and allows efficient input signal coupling in optical fiber amplifier applications. According to the different preferred embodiments, the apparatus can act either simultaneously or independently as a pump combiner, multiple pump injector, signal coupler or pump/signal multiplexer/demultiplexer.
Patent CA-2296773-A1 (CA)
Inventor: JUNTUNEN ROBERT DEAN
IPC: F23N5/26
Filed: 2000-01-21
Abstract: A modulated burner combustion system that prevents the use of components that were originally not commissioned for use in the system. The present invention uses actuators that contain unique stored identification numbers.  When the system is initially configured or commissioned, the unique identification numbers of the actuators are stored in nonvolatile memory in a fuel/air controller. When the system is brought on line, the fuel/air controller microprocessor initially sends false IDs to the actuator together with test control signals to determine if the actuator operates in response to the false identification numbers. If the actuator does operate in response to the false identification numbers, that is an indication that the system has been tampered with and the system is, consequently, shut down. Subsequently, the true identification numbers are transmitted to the actuators with test control signals. The fuel/air controller microprocessor determines if the actuators move properly in response to the test control signals. If they do not move or do not move properly, that is an indication that an actuator is present in the system that was not originally commissioned with the system, or that an actuator is operating improperly. In that case, the system is also shut down. The feedback mechanism of the present invention eliminates the need for expensive safety software and expensive microprocessors in the actuators.

Title: Combination sight glass and sump oil level sensor for a hermetic compressor
Inventor: HERRICK KENT B
IPC: F04B39/02
Filed: 2000-12-04
Abstract: A combination sight glass and optical sensor is provided in the housing of a hermetic compressor to provide effective visual inspection in addition to automatic sensing of the level of oil in an oil sump. A sight glass fitting is provided in the housing and has a first portion that extends outwardly from the housing and that is accessible from outside the compressor. An optical oil level sensing device is removably attached to the first portion of the sight glass with electrical leads extending outside the compressor for connection to a compressor controller. A prism or similar device is attached to the sight glass fitting intermediate the sump oil and the optical sensor. The sensing device includes a light source, a photosensitive detector, and an opaque member to prevent cross coupling between the light source and the detector. Should the oil level in the oil sump fall below a predetermined level, the optical sensor sends a low oil level signal to the controller which interrupts power to the compressor or generates an alarm or status signal. A technician may remove the optical sensor from the sight glass fitting and visually inspect the oil level by looking through the sight glass fitting and prism and into the interior of the compressor housing. One embodiment of the optical sensor will also provide a low oil level signal to the controller when the optical sensor is disengaged or removed from the sight glass.

Abstract: A billing system is provided that allows a consumer to order products from computers connected to the Internet, wherein the consumer is automatically billed for the ordered good or service by its telephone service provider. The billing system comprises a plug-in component (52, 52'), a billing server component (62, 62'), and in some embodiments, a merchant session gateway component (65). When a consumer orders a product over the Internet (20), the plug-in component (52) of the consumer's computer (42) establishes an Internet connection to a billing server (34) located elsewhere on the Internet (20) to order the product. In a first embodiment, the billing server component (62) of the billing server (34) transfers an encrypted version of the product to the plug-in component (52). The plug-in component (52) then disconnects from the Internet (20) and establishes a point-to-point (PPP) connection with the billing server (34). During the PPP connection, the billing server component (64) transfers an access key assigned to the order to the plug-in component (52) so that the plug-in component (52) may decrypt the product. The consumer is charged a unit rate or "drop-charge" for the product by the telephone service provider when the PPP connection is established using a premium telephone number assigned and administered by the telephone service provider. In a second embodiment, the consumer is charged a per minute rate for his of her time spent accessing the product, rather than a drop-charge.
