Title: Foldable worklight with translucent lens
Inventor: GROSSMAN M GARY
IPC: F21L14/00
Filed: 1998-09-09
Abstract: The invention is a portable worklight that includes a housing, bulb, support base and a translucent lens covering a light emitting opening defined by the housing.  Use of the translucent lens eliminates glare and shadowing by diffusing or randomly scattering light emitted from the bulb.  In addition, the housing and support base may be configured such that the housing is rotatably mounted to the support base and the support base is further configured to allow the housing to be folded within the support base.  This reduces the overall size of the light when it is placed in a stored position.   The light may further include a male electrical jack that is used to provided power to the device by coupling an electrical cord to the jack.

Title: Non-uniform memory access (numa) data processing system that buffers potential third node transactions to decrease communication latency
Inventor: DEAN MARK E
IPC: G06F12/08
Filed: 1999-05-12
Abstract: A non-uniform memory access (NUMA) computer system includes an interconnect to which multiple processing nodes (including first, second, and third processing nodes) are coupled. Each of the first, second, and third processing nodes includes at least one processor and a local system memory. The NUMA computer system further includes a transaction buffer, coupled to the interconnect, that stores communication transactions transmitted on the interconnect that are both initiated by and targeted at a processing node other than the third processing node. In response to a determination that a particular communication transaction originally targeting another processing node should be processed by the third processing node, buffer control logic coupled to the transaction buffer causes the particular communication transaction to be retrieved from the transaction buffer and processed by the third processing node. In one embodiment, the interconnect includes a broadcast fabric, and the transaction buffer and buffer control logic form a portion of the third processing node.
Patent CA-2271556-A1 (CA)
Inventor: SMITH JEFFREY
IPC: G06F3/023
Filed: 1999-05-10
Abstract: A method is provided for transforming ordered pairs of keystrokes entered on a keypad with eight or more keys into a full complement of alpha-numeric characters, as might be enterable from a computer keyboard. The method can be utilized with any device that permits an operator to select one of eight keys or other means of generating a distinct electrical or other signal. The keys or positions are arranged radially around a center point in locations corresponding to keys 1-4 and 6-9 of the telephone keypad. Examples of input devices include a numeric keypad, a telephone keypad, and a "joystick." The method employs an alphabet in which each character is represented by a two-stroke pictographic figure. The first stroke proceeds from the position of the first key to be pressed, thence to the center of the keypad or device. The second stroke proceeds from said center to a the position of the second key to be pressed. For the majority of letters, the figure thus formed bears a pictographic resemblance to the printed letter. The operator presses keys corresponding to the beginning and ending points of the pictograph of the desired character or key equivalent.

Title: A procedure and equipment for treating poultry before slaughter
Inventor: ANDREASEN BENT KLOSTER
IPC: A22B3/00
Filed: 1997-12-10
Abstract: The present invention concerns a procedure and equipment for the treatment, such as anaesthetisation or killing, of poultry by using gas. The gas comprises oxygen and carbon dioxide, among other components.  During the treatment, the oxygen concentration is kept constant at a normal level (18 - 22 vol.%). This is important as it allows the poultry to breathe normally while the natural body functions can be maintained in their normal state until anaesthetisation takes place. The concentration of carbon dioxide is increased either continuously or discontinuously. With the present invention it is possible to anaesthetise poultry before slaughter in a way which produces low levels of stress and discomfort in the poultry while, at the same time, the quality of the meat is better than with the use of traditional methods. In the equipment the poultry are exposed to the gas in a chamber (1), that may comprises a belt conveyer (5) and further be separated into three treatment zones (2, 3 and 4).
