Patent GB-2300015-A (GB)
Title: Downhole mixer
Inventor: BAILEY J ROBERT
IPC: E21B27/02
Filed: 1996-04-17
Abstract: The invention discloses an apparatus for storing one or more constituents in a downhole tool. The constituents are segregated from each other until such time as the tool is actuated. At that time, the constituents are forced from their storage position and mixed as they are pushed from their storage position. The resultant mix is then directed to the location where the mixture will finally be placed for eventual solidification. The apparatus and method are useful for inflation of bridge plugs or external casing packers, as well as other downhole applications. Significant time is provided for the surface operator prior to initiation of the constituent elements by segregating the ingredients until shortly before they are mixed and directed to their final destination. Should a problem arise prior to mixing, the unmixed ingredients can be withdrawn from the wellbore.

Title: Multi-channel digital data transmission in a wireless telecommunications system
Inventor: BHAGALIA SHASHIKANT
IPC: H04B1/707
Filed: 1996-05-03
Abstract: A wireless telecommunications system includes a central station which communicates with a plurality of subscriber stations and is connectable to a telecommunications network under a multiplexed multi-channel digital data telecommunications protocol (E1) having a plural number (30) of data channels. Each subscriber station provides a line connection for carrying a predetermined number (2) of digital data channels, where the plural number is greater than the predetermined number. The central station is connectable to each subscriber station via a wireless link under a wireless link protocol having the predetermined number of data channels. The central station includes a central protocol interface for converting between the multi-channel telecommunications protocol and the wireless link protocol for each wireless link. The subscriber station (20) includes a subscriber protocol interface for converting between the wireless link protocol and the multiplexed multi-channel digital data telecommunications protocol with the predetermined number of digital data channels active. By converting an incoming multi-channel digital data protocol to a wireless link protocol, and then reconverting the wireless link protocol to a multi-channel digital data protocol at the other end, it is possible to provide for selective communication in accordance with the multi-channel digital data protocol, despite the limited bandwidth available.

Inventor: KIM JUNG-WOO
IPC: C07D501/06
Filed: 1996-06-28
Abstract: In a process for the preparation of a cephem derivative of formula (1) from a carboxylic acid of formula (2) and a 7-amino-3-cephem-4-carboxylic acid of formula (3), the characterising step comprises reacting the carboxylic acid (2) with a dioxolane based carbodiimide condensing agent of formula (4) and an N-hydroxybenzotriazole of formula (5). This mixture is then used to acylate the 7-amino-3-cephem-4-carboxylic acid (3). The required product is obtained with high purity in a manner that is more economic and industrially feasible than conventional methods (eg using dicyclohexylcarbodiimide). Furthermore, protection of the amino group in the carboxylic acid (2) is not required.   Wherein: X is hydrogen, acetoxymethyl or (2,5-dihydro-6-hydroxy-2-methyl-5-oxo-1,2,4-triazin-3-yl)thiomethyl; Y is CF 3 , NO 2 , CN, halide, trialkyl ammonium, or hydrogen; n = 1,2,3,4; and R 1 and R 2 are independently an alkyl group of 1 to 5 carbon atoms or R 1 and R 2 together represent a carbocyclic group of 3 to 8 carbons atoms.

Title: Method of detecting seam characteristic points
Inventor: ARAKAWA KENICHI
IPC: G05B19/402
Filed: 1996-10-29
Abstract: In order to provide a method of accurately and quickly detecting points characteristic of the presence of a seam for guidance of a robot 1 which injects sealing material along the seam, the robot is equipped with a distance sensor 2 which is scanned across an arbitrary cross section of the workpiece, including the seam. The distance data from the sensor are converted into coordinate data of a series of distance points arranged in a predetermined order, and a statistical value in respect of the distance between adjacent pairs of the points is calculated and used to provide a threshold level for judging discontinuity. The distance between each adjacent pair of points is compared with the discontinuity threshold level so as to detect a pair of adjacent points which are separated from each other by a distance equal to or greater than the threshold level, the centre point between the detected pair being used as a point which is characteristic of the presence of the seam.

Title: Simultaneous display of pictures from automatic channel search
Inventor: YOON YEO JOON
IPC: H04N5/45
Filed: 1997-12-11
Abstract: A method for displaying broadcast signals of searched channels in an image receiving apparatus comprises searching broadcast channels in a sequential manner in accordance with an automatic search command, storing channels having television broadcast signals and displaying pictures from the stored channels simultaneously on a display partitioned in PIP manner. Television broadcast signals of a channel searched by a main picture receiving station 5 are received to display them on a first area in the form of a moving picture. Television broadcast signals of channels other than the channel of said main picture receiving station 5 are received and stored to insert them into the television broadcast signals of said main picture receiving station 5 in a form of a PIP so as to display them on the partitioned areas in a sequential manner starting from a second area and in a form of a still picture. The steps are repeated starting from the second step upon encountering a last channel at the third step.
Patent GB-978438-A (GB)
Abstract: 978,438. Valves. MISSION MANUFACTURING CO. May 19, 1961 [May 15, 1961], No. 18248/61. Heading F2V. An oil-feed control means for a heater comprises an inlet valve 38 controlled by an intermediate lever 27 operable by a lever 26 attached to a float 5 and by a thermostatically controlled rocker lever mechanism 45. The inlet valve is operated normally via a bimetal spring strip 34 which, at one end is pivoted, together with the float lever 26, on a bracket 23 and, at its other end, contacts the top of the float. The intermediate lever 27 is also pivoted on the bracket and is provided with an abutment 33 which contacts the underside of the bimetal strip opposite the valve 38. The rocker lever 45 is pivoted at 46 on a bracket 39 mounted on the cover 10 of the housing and is controlled by an over-centre spring 44. One end of the lever contacts the float lever 25 and the other end contacts the free end of a second bimetal strip 48 secured at its other end to the cover. In normal operation, the float controls the valve via the pivoted bimetal strip 34, the latter strip varying its contact pressure on the float in dependence on the viscosity of the oil. If the level of the oil exceeds a certain value, the pivoted lever is moved over-centre by the float arm so that its end contacts a projection 28 on the intermediate lever 27 and thus quickly closes the valve. The valve may also be closed independently of the float by means of the bimetal strip 48, which, upon excessive increase temperature, bends downwardly so as to contact the other end of the lever 45 and cause closure of the valve as previously explained. An indicating plunger 50 is provided which is connected to the lever 45 and, when the latter is actuated to close the valve, is lifted above the level of the cover. By depressing the plunger the lever is returned to its normal position. The outlet 3 from the housing is controlled by a valve 57, Fig. 11, which is actuated by a screwed spindle 56. The valve is in the form of a sleeve which is provided with a tapering slot 58 so that a graduated flow is obtained. At one extreme position of the sleeve a spring-loaded ball therein completely closes the outlet. In order to prevent the entry of oil to the housing when the outlet is completely closed, a pin 61 on the spindle 56 is arranged to abut a helical extension 30 on the lever 27 and thereby close the valve 38. The cover 10 is clamped on top of the housing by a band 21 and a lever-locking device 20, Fig. 8. The float may be filled with gas or evacuated.
