Title: Integrated circuits
Inventor: CHEW NIGEL GORDON
IPC: H01L21/268
Filed: 1982-11-08
Abstract: Components, e.g. diode 6, 7, 8, on a crystalline substrate are electrically isolated by forming therebetween amorphous regions 11, 12, 13 using laser irradiation. Typically the laser radiation has a wavelength of less than 400 nm, a pulse length of between 0.1 and 10 nanoseconds, and a power density of between 0.1 and 0.8 J/cm<2>, so that most of the radiation is absorbed in the top 3000 ANGSTROM  of the substrate which rapidly melts and then rapidly freezes into an amorphous state. The substrate may have large areas, or its total surface, formed into an amorphous layer which is then subsequently annealed to its crystalline form in selected areas. Circuit elements such as resistive channels may have their values trimmed by selective amorphisation using the laser beam The substrate material may be Si, Ge, GaAs, GaAlAs, InP or InAlP. <IMAGE>

Title: Positioning of the truing tool of an internal grinding machine
Inventor: DIESING KURT
IPC: B24B49/18
Filed: 1983-03-29
Abstract: The invention relates to a method and device for positioning the truing tool of an internal grinding machine. During an adjusting movement of a cross slide 4 to a different bore diameter to be ground, the truing tool 8 maintains its position unchanged in relation to the grinding element 10, and during a second adjusting movement of the cross slide 4 to compensate for the reduction in grinding element diameter, the truing tool 8 follows the cross slide 4. In the preferred device, the truing tool 8 is disposed on a truing slide 7 movable in relation to the cross slide 4, and can be driven via a screw spindle 1, and can be connected via a clamping rod 13 and clamping devices 14, 15 to the cross slide 4, or to a fixed part of the machine, for example, the guide member 3. As a result the truing tool is constrainedly positioned in relation to the bore diameter via only one adjusting element. <IMAGE>

Patent GB-2127069-A (GB)
Title: Drill stem test and perforating system
Inventor: VANN ROY R
IPC: E21B49/08
Filed: 1983-08-26
Abstract: A pipe string with a valve 60, pressure responsive means 70, packer 30, firing mechanism 80 and perforating gun 50 are suspended within a well to test a formation. The packer 30 is set to form an upper 32 and lower 34 annulus, and the valve 60 and pressure responsive means 70 are disposed above the packer 30 in the upper annulus 32. A force transmission means extends from the pressure responsive means 70 to the firing mechanism 80 in the lower annulus 34. The valve 60 is initially closed to prevent fluid flow through the flow bore of the pipe string. The upper annulus 32 is pressurized to open the valve 60 and create a pressure differential across the pressure responsive means 70. The pressure responsive means 70 then transmits a force through the force transmission means to the firing mechanism 80 to actuate the firing mechanism and detonate the perforating gun 50. Fluid from the formation then flows through the perforations and up the flow bore of the pipe string to the surface. <IMAGE>

Title: Odour neutralisation
Inventor: BURGER MANFRED R
IPC: B03C3/16
Filed: 1984-02-21
Abstract: Apparatus for neutralizing the odour of air flowing through a flow duct (1) and polluted by odorous components (20) provides for use of an odour adsorber (9) contained in a container (4), which odour adsorber is introduced into the flow duct (1) of an exhaust air system as a liquid mist or aerosol (21) through a pipe (5) as a result of a pressure differential between the inside of the container (4) and the ambient air. The exhaust airflow is ionized to negative polarity by a sharp-edged metal element (10) and the odorous components (20), which are preferentially ionized because of their larger molecule size, are neutralized by the adsorber fluid particles (21) charged to positive polarity by means of combination and electrostatic attraction. <IMAGE>

Patent GB-2213403-A (GB)
Title: Method and apparatus for growing CdxHg1-xTe
Inventor: VERE ANTHONY WORSWICK
IPC: C30B11/00
Filed: 1985-12-05
Abstract: The material CdxHg1-xTe is grown in a thin walled sealed ampoule contained in a pressure vessel. Problems of uniformity of the material is reduced by a specific combination of energetic mixing of a melt of Cd, Hg, and Te and a rapid controlled freezing of a disc of CdxHg1-xTe following by annealing. The mixing may be a rapid rotation, e.g. 900-930 r.p.m., of the ampoule with rapid reversal of direction every few seconds. Controlled freezing is obtained by cooling a base plate, supporting the ampoule, to 300 DEG C or lower with liquid or gaseous coolant. Annealing is obtained by raising the ampoule to 650 DEG C - 690 DEG C at the hottest end with a temperature gradient of 5 DEG  to 20 DEG C per cm along the ampoule length. These temperatures and gradient values are held for 24 hours or more before the ampoule is cooled to 450 DEG C or below.

Title: Balanced rotary cylinder reciprocating piston i.c. engine
Inventor: MACDONALD BRIAN GALE
IPC: F02B57/06
Filed: 1986-04-12
Abstract: A two stroke engine has a rotary cylinder member (12) and a piston assembly (13) acting within the cylinder. The cylinder (12) rotates on a fixed mounting (11) about an axis (15) which is both the centre of rotation and the centre of balance of the engine. The piston assembly (13) includes a connecting rod (18) having its big end (19) mounted on an offset crank pin (17) so that it is pivoted about an axis (26) which is both the axis of pivoting movement and the axis of balance of the piston assembly. Similarly the piston (22) is mounted to a gudgeon pin (21) in such a way that the rocking movement of the piston in use is about an axis coinciding with its own axis of balance. Because the entire engine and each sub-assembly is arranged to rotate or rock about its own axis of balance, the amount of vibration to be expected is very low and the engine can be run at relatively high speed with an excellent power to weight ratio. Two cylinder and three cylinder versions of the engine are also described (Figs. 8 to 11). <IMAGE>
