Title: Reduction of parametrically-generated negative resistance in amplifier input using feedback
Inventor: SUCKLING CHARLES WILLIAM
IPC: H03F1/26
Filed: 1992-06-30
Abstract: This invention relates to the use of feedback circuitry in a high-efficiency power amplifier using gallium arsenide heterojunction bipolar transistors (GaAs HBTs). The feedback reduces the effects of parametrically- generated negative resistance at the amplifier input terminals. If uncompensated, this negative resistance often acts in conjunction with the remaining amplifier circuitry to generate spurious (undesired) signals. The spurious signals usually appear as oscillations at sub-multiples of the signal frequency, or as increased noise-spectral density over a band of frequencies. This enables HBTs to operate in high-efficiency amplifier circuits with minimum tendency to generate spurious outputs. <IMAGE>

Title: Vehicle measurement systems
Inventor: COACHWORTH SIMON
IPC: G01B17/00
Filed: 1992-08-14
Abstract: The system comprises an array of microphones 18 and a spark emitter 24. 46 mounted on a vehicle. Sparking produces sound bursts which travels to the microphones 18. From detection of transmission times, the position of the emitter 24, 46 is found. Sound velocities are determined in various directions to ensure the air is homogeneous, else corrections for sound speed variations are applied or data is rejected. Position data determined from various microphones 18 are compared to ensure repeated measurement accuracy. The apparatus includes simple circuitry with fewer received signal processing channels than microphones 18 and intelligent selection of active microphones in consequence. An emitter can be connected to the upper vehicle body via a bent coupler 78, which can pass around a wing for example. This allows the system, which is ground based, to be used for measurements of the upper vehicle body. The positions of microphones 18 are determined precisely before use of the system, using a calibration jig 124. Errors in microphone positioning are then corrected for in the measurements. <IMAGE>

Title: Lighting assembly
Inventor: WEIGERT DEDO ARNDT
IPC: F21V11/06
Filed: 1993-05-07
Abstract: A lighting assembly has a grid (5) arranged to be adjustable at a light outlet of a housing (1). In one embodiment, three grids (4, 5, 6), are arranged one behind the other in the direction of light leaving the housing, which grids are movable relative to one another. When the position of the intermediate grid (5) of such a lamp assembly is adjusted, the light emission angle of the lighting assembly is modified. When the slats of the grids (4, 5, 6) are arranged in true alignment to one another, a relatively small light emission angle (ZB) results. By adjusting the grids, for example by one half step adjustments relative to one another, the light emission angle is enlarged accordingly. Thus, a directional effect can be achieved without a focusing effect, even with the use of fluorescent tubes (2). <IMAGE>

Title: Inorganic skin film produced by pulsed plating process
Inventor: TABATA MASAMUNE
IPC: F16C33/12
Filed: 1994-04-29
Abstract: A slide surface construction which is an inorganic skin film is formed of an aggregate of crystals, of e.g. Fe, Cr, Mo, W, Ta, Sr, Nb or V, having a body-centered cubic structure. The aggregate includes a large number of (222) oriented crystals with their (222) planes (by Miller indices) oriented toward a slide surface. At least some of these (222) oriented Fe crystals are hexangular pyramid-shaped crystals having six ridge lines. These Fe crystals having six ridge lines ensure that the oil retention of the slide surface construction can be improved, and a slide load acting on the slide surface can be finely divided. The skin film is produced by controlling the output of a plating energy source to produce a pulse waveform such that said output is increased from minimum value to reach a maximum value and then is reduced to said minimum value; and setting a ratio TON/TC of an output time TON to a cycle time TC within a range of TON/TC </= 0.45, wherein said output time TON is from a start point of increasing said output to a start point of reducing said output, and said cycle time TC is a time required for one cycle from an increasing-start point to a next increasing-start point of said output. The skin film may be produced by electrolytic plating, chemical vapour deposition or a physical vapour deposition technique.

Title: Treating earthenware bodies
Inventor: MACMULLEN PAUL NEIL
IPC: C04B41/52
Filed: 1993-10-15
Abstract: A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellant material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellant material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.

Title: Water heating system
Inventor: CARRUTHERS THOMAS ROBISON
IPC: F24D19/10
Filed: 1996-02-01
Abstract: A central heating and hot water system has a condensing type of gas-fired boiler 11 connected to supply hot water to radiators 12 and to a cylinder 13 for indirect heating of tap water stored in the cylinder 13. A system controller 40 is arranged to sense the temperature of the stored water in the cylinder 13 and, when the sensed temperature is below a first value, to cause the boiler 11 in its ON condition to deliver its full output to the cylinder 13 until such time as the sensed temperature equals said first value. Thereafter, the controller 40 is arranged to cause the boiler 11 to deliver its full output to the radiators 12 whilst thermostatically sensing the temperature of the water in the radiators 12. When the sensed temperature exceeds a second value, the controller 40 causes the boiler 11 to be held in its OFF condition whilst recirculating the radiator water around the radiators 12 in a circuit which bypasses the boiler 11. Said second value is selected so that the boiler 11 operates in its condensing mode when delivering to the radiators 12.
