Abstract: A method of making a titanium boride metal matrix alloy, by firing a particulate reaction mixture comprising titanium, matrix material and a source of boron (e.g. boron carbide), so that the titanium and boron react exothermically to form a dispersion of fine particles (preferably greater than 1 micron and less than 10 microns in size) comprising titanium boride (plus titanium carbide where the source of boron is boron carbide) in a predominantly metal matrix. The titanium and matrix are preferably added as a titanium alloy such as ferrotitanium (e.g. eutectic ferrotitanium) or titanium-aluminium. The reaction conditions are preferably selected so that during the reaction a molten zone moves through the body of the reaction mixture, and the average size of the resulting hard particles is uniform throughout the resulting dispersion.
Patent GB-2264003-A (GB)
Title: Field-assisted bonding
Inventor: ROGERS TONY WILLIAM JAMES
IPC: H01L21/58
Filed: 1993-03-26
Abstract: The invention relates to a method of bonding together two workpieces, of which at least one is (or has a surface which is) of a material which is electrically substantially non-conductive, by the field-assisted bonding process known as electrostatic bonding which comprises the steps of positioning the workpieces in contact with one another at a common interface, maintaining at least their interface at an elevated temperature, applying a substantial first voltage between them so as to establish at the interface an electrostatic attraction which forces the workpiece surfaces into intimate contact with one another and causes them to bond to one another, and thereafter removing the applied voltage and allowing the workpieces to cool. According to the invention this process is improved by including the additional step, after application of the first voltage and while still maintaining the said interface at elevated temperature, of applying between the workpieces a second voltage of opposite polarity to the first voltage.

Abstract: A valve module, particularly for use in water service and metering systems, has a main conduit with one or more branch pipes and is provided at the ends of the conduit with complementary screw-threads so as to be able to be connected in line with further similar modules. A ring 20 at one end of the main conduit carries the female screw-thread and is formed with an integral detent 21 which engages a resilient member 18 adjacent the male screw-thread at the other end of a further module in order to set the relative angular dispositions of two adjoining modules.

Title: Lidar with smear detector
Inventor: AKASU MASAHIRA
IPC: G01S17/93
Filed: 1994-04-05
Abstract: An optical distance measurement apparatus for measuring the distance to an object 7 on the basis of the round-trip time of the light to and from the object 7 includes an object detector means 32 and a smear detector means 33. The smear detector means 33 detects a smear when the ratio of unsuccessful measurements (i.e., the measurements by which no object is detected) is greater than or equal to a predetermined level. Alternatively, the number of successive measurements of a distance less than a predetermined threshold level (e.g., 50 meters) is stored in a counter, and the smear is detected when the content of the counter becomes greater than or equal to a predetermined number. Repeated measurements of the range to the same target can be ignored for these purposes. Once a smear has been detected, it may be considered to remain there until a target at a range in excess of a second, higher (eg 60 meters) threshold is detected. <IMAGE>

Patent GB-942723-A (GB)
Abstract: 942,723. Controlling gas burners. G. KROMSCHRODER A.G. April 27, 1962 [April 27, 1961 (2)], No. 16155/62. Addition to 904,179. Heading F4T. The invention of the parent Specification is modified by arranging that the gas supply to the pilot burner 13c controlling the first relay 10a is controlled by a valve 71b operated by a thermocouple 15b heated by a second pilot burner 13b. The invention of the parent Specification has a single pilot burner and the valve therefor is actuated by the second relay 30. The present invention has a plurality of pilot burners 13, 13a, 13b, 13c, the thermocouple 15 of pilot 13 actuating the valve 71 of pilot 13a and so on and the valve 14 of the pilot 13 being actuated by the second relay 30. A main burner is associated with each pilot burner, all the main burners being controlled by a single valve 18. The Figure shows the condition of the relays during burner operation. When the burners are inoperative contacts 8, 9 and 8a, 9a are closed and contacts 16, 17 open, and contacts 31, 32 and 33, 34 are open. On closing a mains switch 1 an ignition transformer 11 is energized to heat series connected coils 12a for igniting the pilot burners and the coil of the second relay 30 is energized through closed contacts 8a, 9a to open pilot valve 14 and to close contacts 31, 32 and holding contacts 33, 34. The pilot burner 13 then ignites and its thermocouple 15 opens pilot valve 71 and the next pilot burner 13a ignites. This process continues until the first pilot burner 13c ignites and its thermocouple 15c energizes the coil of the first relay 10a which therefore opens contacts 8, 9 to de-energize the ignition transformer 11 and closes contacts 16, 17. The main fuel valve 18 is then opened through contacts 31, 32 of the second relay 30 and through contacts 16, 17 of the first relay 10a. If the electrical power fails the second relay 30 is de-energized and immediately closes the main valve 18 and the pilot valve 14. The other pilot valves 71, 71a, 71b then close in sequence. The circuit also includes a thermostat 4, a thermal cut-off 7 which breaks the circuit after a predetermined time under the heavy current conditions caused by energization of the igniter, a pressure switch 26 with diaphragm 27, and a rectifier 56. In a modified arrangement, Fig. 3, not shown, having only three main burners the pilot burners therefor are controlled by three electromagnetic pilot valves 14, 14a, 14b energized from the mains through contacts 31, 32 of the second relay 30, two of the pilot valves 14a, 14b being also controlled by relays 70, 70a energized by thermocouples 15, 15a heated by other pilot burners. The coil igniters are replaced by spark igniters. In another modified arrangement, Fig. 2 (not shown), each main burner is controlled individually by a thermostat 4a, 4b, 4c, 4d responsive to a roomtemperature and a main fuel valve 18a, 18b, 18c, 18d. Each coil igniter has its own ignition transformer.
