Title: Variable flow sliding sleeve valve and positioning shifting tool therefor.
Inventor: MASHAW JUNIOR HOWARD RICHARDSO
IPC: E21B34/14
Filed: 1992-12-23
Abstract: A sliding sleeve valve (10) for use in a flow conduit has a sleeve 13 which is movable between open, intermediate and closed positions to control and vary the flow through the valve. The sleeve 13 is retained in its selected position by lugs 13a engaging one of a series of positioning grooves 17. As the sleeve 13 is moved from the open position to intermediate positions towards the zero-flow closed position, the area open for flow at each position is progressively reduced e.g. by covering openings 21. A pressure operated shifting tool (not shown) can be selectively located in the valve to engage the sleeve and move it upwardly or downwardly between said positions. The tool is automatically disengaged from the sleeve for retrieval. An invertible shifting module in the shifting tool has a positioning sleeve which determines the distance the sleeve is moved when the tool is operated. The shifting tool also includes means for disengaging the sleeve valve if it does not automatically disengage after operation, and an emergency disconnect for disconnecting a flow conduit used to lower the shifting tool. <IMAGE>

IPC: C10L5/28
Abstract: 927,231. Fuel briquettes. COAL INDUSTRY (PATENTS) Ltd. Sept. 2, 1959 [June 4, 1958; Aug. 21, 1959], Nos. 17821/58 and 28626/59. Drawings to Specification. Class 91 Fuel briquettes comprising carbonaceous materials such as coal or coke and a binder such as pitch are treated to reduce the smoke emitted upon eventual combustion by heating a bed of the briquettes for a time of less than two hours while passing through the bed a stream of an oxygen-containing gas such as air, to a temperature between 150‹ and 350‹C. and above the temperature at which rapid oxidation occurs but below that at which the briquettes will burn, the thus treated briquettes being then quenched with water with or without an intermediate cooling step in which the briquettes are cooled in an oxygen-containing atmosphere. The preferred time of the treatment is between 40 and 100 minutes and the depth of the bed of briquettes between 2 feet and 3 feet 6 inches. The temperature variation through a vertical cross-section of the bed preferably does not exceed 10‹C. Apparatus for carrying out the treatment comprises a horizontal tunnel furnace through which a bed of briquettes is moved on an endless conveyer through which a stream of air is drawn. Specification 807,433 is referred to.

Title: A method for electrolytically converting ammonia in a gas stream to nitrogen
Inventor: GILROY DANIEL
IPC: C25B1/24
Filed: 1993-05-07
Abstract: A process for converting ammonia in a gas stream to nitrogen comprises contacting the gas stream with an electrolyte containing bromide and hypobromite ions such that the ammonia is dissolved and oxidised by the hypobromite ions to nitrogen, and thereafter passing the electrolyte through an electrochemical cell containing an anode and a cathode to regenerate the hyperbromite ions by the action of an electric current flowing across the cell. The conversion of ammonia to nitrogen in accordance with the invention is advantageous as nitrogen may be disposed of without harm to the environment whilst ammonia has toxic effects.

Title: Shower using stored hot water and instantaneous heating
Inventor: BENSON NEVILLE IAN
IPC: F24D17/00
Filed: 1996-02-01
Abstract: Warm water for a shower is normally provided by mixing stored hot water 10 with cold water 11 in a mixing valve 60, but a temperature sensor 20 switches on an electrical instantaneous heater 31, 32 if the temperature of the hot water falls below a certain level. In "electric" mode, the heater is supplied with cold water only, to conserve the remaining hot water, and the user can select at 70 the desired power output of the heater (one element, the other or both) and the output flow rate provided by pump 80. In "normal" mode, the mixing valve controls temperature and flow rate of the warm water. Switching to "electric" mode can be effected manually if desired, rather than waiting for the temperature sensor to respond.

Title: Estimating LSI areas in an automatic layout system
Inventor: MATUMURA MIHO
IPC: G06F17/50
Filed: 1996-04-15
Abstract: LSI area is estimated from design data containing a net list and a cell library. Firstly, the layout style of the LSI is determined from this data. Then a first estimate is performed if i/o cells are present in design and a second estimate is calculated depending on the whether the LSI is of the standard, building block or mixed type, the second estimate being performed with the aid of coefficients related to the number and spacing of interconnect layers. One of the area estimates is then selected for use in a floor planning process.

Title: Bobbin thread payoff detection device for sewing machines
Inventor: PASSMORE THOMAS ISAAC
IPC: D05B59/02
Filed: 1996-04-30
Abstract: A detection device which provides a means of confirmation that thread is being withdrawn from the bobbin within the sewing machine has a sensor (7) focused on the bobbin (4). This signal is electronically synchronised with an additional signal from a needle position sensor (8) so that at a given needle position the sensor (7) will detect either a reflective or non-reflective area which is marked onto the surfaces of the bobbin which in turn determines whether the bobbin has rotated and generates an alarm if bobbin rotation has not been detected. A self checking facility built into the device interrogates the focused sensor to ensure that any debris that may affect correct operation is detected and an early warning is issued.
