Patent GB-2106130-A (GB)
Title: Gasification
Inventor: WILSON HENRY THOMAS
IPC: C10J3/46
Filed: 1982-09-03
Abstract: This invention relates to a gasification process in which a particulate feedstock is fed to a cyclonic reactor (10) in a stream of reaction gas through an inlet (8). The reactor (10) allows the mixture to fully react while reducing the entrainment of particles to the product gas discharged through pipe (14) upwardly substantially along the cyclonic axis of the reactor (10). The product gas is further filtered in an ash cylone (16), and the heat utilized in a waste heat boiler (26). The solid end liquid residues from the reaction are collected and discharged at the base of the reactor (10). <IMAGE>
Patent GB-2140615-A (GB)
Title: Thermistor composite
Inventor: CAMP PHILIP GEORGE
IPC: G01K7/22
Filed: 1983-03-22
Abstract: A temperature sensor for a motor vehicle comprises a composite of PTC and NTC thermistors (1, 2,3) whose overall temperature characteristic (c) is negative with a plateau (P) centered on the normal working temperature (88°C) to be sensed, so that tolerances in the sensing system and normal fluctuations of the working temperature will tend not to be registered by the vehicle temperature gauge. Thus only abnormal variations in temperature caused by a fault or overload condition will be indicated.

Title: Safety closure with click mechanism
Inventor: BOOKLESS PAUL ANTHONY
IPC: B65D50/04
Filed: 1983-04-22
Abstract: A safety closure comprises an outer closure member (1) and an inner closure member (2) having crown portions (7 and 8) respectively. The skirt portion of the inner closure member (2) is provided with an outwardly convex surface (16), while the skirt portion of the outer closure (1) is provided with a plain vertex (17). Two engageable splines (4 and 5) are provided and the inner and outer closure members will normally rotate relative to each other without interengagement. To remove the closure an axial force is applied together with a radial force which causes vertex (17) to slide down surface (16). The splines are thereby engaged using a reduced axial force. Pawl and ratchet means (9 and 10) disposed on the respective crown portions of the closure members provide clicking sounds and provide means biassing the closure members apart. Without separate biassing means an improved sounding box is provided. <IMAGE>

Patent GB-2122670-A (GB)
Title: Improvements relating to rock bits
Inventor: OLIVER MICHAEL SMITH
IPC: E21B10/61
Filed: 1983-06-24
Abstract: A rock bit (10) has a nozzle (30) in its cutting face (16) protected from hydraulic erosion problems that could result in expulsion of the nozzle by washout of bit material surrounding the nozzle due to the accelerated passage of drilling mud through the nozzle. Since the nozzle is positioned near the borehole bottom, hydraulic fluid (mud) that is accelerated through the nozzle impacts the borehole bottom and is reflected back against the face (16) of the rock bit, thus causing erosion of bit material surrounding the nozzle. The nozzle (30) has an enlarged nozzle face (38) around its exit opening (36) that resists erosion of the bit material surrounding the nozzle while the nozzle (30) is retained in the rock bit body by a screw thread (42) positioned well within the rock bit face. The nozzle body is composed of tungsten carbide with a steel alloy threaded sleeve (42) brazed to the nozzle body. <IMAGE>

Title: Loudspeaker cabinet
Inventor: MACLEOD TORQUIL HECTOR REES
IPC: H04R1/28
Filed: 1983-09-03
Abstract: The space within a loudspeaker cabinet is divided into a series of interconnecting spaces of non-rectangular section. A rectangular loudspeaker cabinet has four equal sized sheets or strips 20 of wood, plastics or other material located to extend between diagonally opposite edges of the top and bottom of the cabinet. The Figure shows only two of the sheets or strips; the other two extend one from each of the other top edges to the opposite bottom edge. Thus the four sheets or strips 20 meet at the centre of the cabinet and divide the space into a series of interconnecting spaces with complete interruption between each pair of opposite walls. The arrangement eliminates production of standing waves. <IMAGE>

The contact adhesive strip 11 enables the tile to be fixed to an existing surface. <IMAGE>
Patent GB-2191304-A (GB)
Title: Integrated optical channel waveguide
Inventor: GRANT MICHAEL FRANCIS
IPC: G02B6/134
Filed: 1986-06-03
Abstract: The refractive index distribution in both width and depth in a waveguide produced by indiffusion or ion exchange (eg. if titanium into lithium niobate) is controlled by an initial pattern produced on the waveguide substrate (1) by using a single stage photolithographic process. The initial pattern on the substrate is chosen so as to produce the required distribution and for each waveguide may comprise at least two strips (11), each adjacent pair of strips being separated by a respective gap (9). The refractive index variation is controlled by varying the strip width to gap ratio. Waveguide mode size can be tapered along the length of the waveguide by corresponding variations in the initial pattern. Losses at waveguide bends can be reduced by employing a pattern which increases the refractive index increase at the inside of the bend relative to the outside thereof. <IMAGE>
