Patent EP-0651916-A1 (EP)
Inventor: FLYNN STEPHEN JOHN
IPC: H05K3/46
Filed: 1993-06-30
Abstract: An RF waveguide signal transition apparatus for minimizing leakage at RF frequency is described which consists of providing a plurality of plated through-holes (16) of blind holes in a circuit board (10). The plated holes (16) are disposed on the circumference of a circle around the RF waveguide to microstrip transition of probe (14) and each of the plated holes (16) is connected to a ground plane (24). The size of distribution of the plated holes provides a barrier to signal leakage at RF frequencies in the range 10.95-11.7 GHz and they also provide a transition impedance similar to the 50 ohm characteristic impedance providing satisfactory matching and minimizing leakage into the board. The apparatus can also be used to minimise leakage from microstrip to microstrip transitions passing through the circuit board.

Title: Process for the production and recovery of halonitroalkanes in high yield.
Inventor: TIMBERLAKE LARRY D
IPC: C07C201/12
Filed: 1993-07-02
Abstract: A process for the preparation of halonitroalkanes, e.g. bromonitromethane, is disclosed in which a nitroalkane is reacted with an alkali metal base or an alkaline earth metal base, and the resulting nitroalkane salt is halogenated to form the halonitroalkane in a reaction mixture. The process is improved by acidifying the reaction mixture, preferably to pH = 0-4, and thereafter recovering the halonitroalkane by azeotropic distillation of the reaction mixture. The acidification step increases the amount of halonitroalkane recovered, as compared to prior art processes in which the reaction mixture is distilled without prior acidification.

Title: Germicidal air filter.
Inventor: PICK WILLIAM E
IPC: A61L9/20
Filed: 1993-09-23
Abstract: A germicidal air purifier for trapping and destroying airborne microorganisms is disclosed. The air purifier includes an ultraviolet radiation source and a juxtaposed filter medium. A one of the ultraviolet radiation source and the filter medium is fixed and the other is displaceable so that at least an upstream side of the filter medium is systematically exposed to germicidal levels of radiation. In a first preferred embodiment, a fixed ultraviolet lamp irradiates a cylindrical air filter which is rotated on its longitudinal axis in close proximity to the lamp so that the upstream side of the filter is systematically irradiated. In a second preferred embodiment, a radiant lamp fixture is moved reciprocally across an upstream side of a planar filter to systematically irradiate the filter. In a third preferred embodiment, a radiant lamp fixture is rotated about an axis which is orthogonal to its longitudinal midpoint so that a circular area of a planar filter is irradiated. The advantage is that microorganisms trapped on the filters are exposed to a lethal dose of radiation and the air purifier is consistently effective at destroying a significant percentage of airborne microorganisms suspended in air passed through the filter.

Abstract: A decrease in the speed of arithmetic operations is achieved in a three-dimensional computer graphics process. In a pre-process unit (14), a model coordinate system of a model read out from a model information storage unit (11) to a display coordinate system, and the model is converted to a texture in a picture-drawing process unit (15). There is provided a virtual canvas on which the model is attached, and the virtual canvas is subjected to perspective transformation. In the perspective transformation, polygon-by-polygon transformation is not performed, but four apices surrounding a texture model are subjected to arithmetic operations, and an approximation process is performed among the apices. When the texture model is attached to the imaginary canvas, a texture digital differential arithmetics (DDA) operation is performed and the obtained data is sent to a display (18) via a display control unit (17).

Abstract: In a mimeographic printing machine in which a mimeographic stencil paper is initially set in such a manner that the front leading end of the mimeographic stencil paper is located in a stencil paper passageway between stencil making means and a rotary cylindrical printing drum, the mimeographic printing machine has stencil paper conveying means, a stencil paper sensor and control means. The control means controls the stencil paper conveying means as follows: In the case where the stencil paper sensor does not detect the presence of the stencil paper when the stencil paper is initially set, the control means causes the stencil paper conveying means to forwardly move the stencil paper until, after the sensor detects the passage of the front leading end of the stencil paper, the front leading end of the stencil paper reaches a predetermined position. On the other hand, in the case where the sensor detects the presence of the stencil paper when the stencil paper is initially set, the control means causes the stencil paper conveying means to backwardly move the stencil paper until the sensor detects the passage of the front leading end of the stencil paper, and then to forwardly move the stencil paper until, after the sensor detects the passage of the front leading end of the stencil paper, the front leading end of the stencil paper reaches the predetermined position.

the temperature of the said mandrel and an extrusion pressure on the elastomer are set in such a manner that they fall within the range where a range permitting hot drawing of the tube preform and a range free from the occurrence of bubbles on the surface of the tube preform overlap, which ranges being determined in advance on the basis of the temperature of the heated mandrel and the extrusion pressure on the elastomer as parameters. The method of the present invention can provide a TPU tube having a fine hot drawability while overcoming poor appearance due to the occurrence of bubbles or granular structure. In addition, TPU tubes having stable quality are continuously produced, thus increasing the yield thereof.

The system includes a cylinder cycle marker circuit (16) for generating an engine cycle reference signal based on the detected operational position of the engine as indicated by a TDC signal and a fly wheel teeth (FWT) signal. The system also includes a cylinder sequencer (22) for controlling the sequence of combustion in respective cylinders of the engine responsive to the engine cycle reference signal. A multiplying circuit (14) is provided for multiplying the incoming FWT signal to produce a high resolution engine rotation signal which is a programmable integer multiple of the FWT signal. Injector and ignition timing control signals can be delayed by timers (24, 26) with a programmable delay specified in terms of an integer multiple of the multiplied FWT signal, and can therefore be precisely set in terms of  DEG  crank angle before TDC regardless of the engine speed. Furthermore, being angle referenced each programmable delay at least maintains the last calculated advance setting regardless of changes in engine speed.
