Title: Irradiation of a continuously flowing fluid
Inventor: SMITH RICHARD AUSTIN
IPC: C02F1/30
Filed: 1988-02-01
Abstract: A continuously flowing fluid is irradiated by a radioactive source 6 operating on a transport passage through which the fluid passes at a rate dependent on the radioactive source output and the degree of irradiation required. The radioactive source may be contained in a central conduit 2 around which is a concentric conduit 8 for containing the fluid flow 4. The fluid may alternatively flow through a helical passage (Figure 4), a plurality of passages around the central conduit (Fig 2) or a vicusoidally convoluted passage (Figure 1). A plurality of sources may be located in a tank through which the fluid flows, the tank containing stirring means (Figure 5) or baffles (Figure 6). <IMAGE>

Title: Helmet for protective wear
Inventor: COLES TIMOTHY PAUL
IPC: A42B3/04
Filed: 1988-03-17
Abstract: A helmet for use with protective clothing of the sort worn in isolators is presently heavy and complex - it is basically a large gauge wire framework around which is wrapped a flexible plastic "bag" with a clear rigid plastic faceplate sealed into it. Not only is this sort of helmet intrinsically heavy, but because the rest of the suit "hangs" from it its effective weight is even greater. All this weight rests on the shoulders of the operator, and fatigue rapidly results. To avoid or mitigate this problem the invention proposes that the helmet be formed from a suitably-sized tube (18) of rigid or semi-rigid (unplasticized) transparent plastics material sealed at the top by a bonded disc (19) of flexible plastics material, and which, at its lower end, is bonded to an inflatable flexible plastics material "dough nut" (20) similar to a child's bathing ring. <IMAGE>

Title: Hydrant
Inventor: VELA ALARCO FERNANDO AGUSTIN
IPC: E03B9/04
Filed: 1988-04-25
Abstract: A hydrant constituted by an elongated body 1 intended to be partly buried comprises a closure ring 9 upon which a seal 11 of the hydrant acts. Sealing is controlled from the top end of the hydrant by a transmission shaft 13 which moves axially to apply the seal against the closing ring. The transmission shaft comprises at its uppermost region, replacing the standard nut, a helical channel (20; Fig. 3) having wide pitch and hemispherical section. A cap 21 mounted to rotate freely in the body is provided on its side wall with a plurality of openings or housings (24; Fig. 2) for balls 25, the housings being frusto-conical so that the balls may enter them to engage the helical channel so that, by means of a small angular rotation of the actuating head a considerable axial displacement of the transmission shaft towards the closing ring is achieved with minimum effort thus converting the rotary movement of the cap into an axial movement of the shaft. A hydrant drain valve (Fig. 5) is also disclosed. <IMAGE>

Title: Heat treatment of metallic workpieces
Inventor: SCHWING EWALD
IPC: C21D1/76
Filed: 1988-05-06
Abstract: In a process for the heat treatment of metallic workpieces in a gas-permeated fluidised bed of refractory particles, in which the workpiece is heated in the fluidised bed to a treatment temperature of 500 to 650 DEG C in an inert atmosphere, the workpiece after being heated to the treatment temperature is oxidised in the fluidised bed by means of a stream of oxidising gas, and then nitro-carburised in a mixture of ammonia, nitrogen and a carbon-rich gas, wherein during the nitrocarburisation, the volumetric proportion of ammonia in the stream of mixed gases is lowered, continuously or in steps, while the volumetric proportion of nitrogen is increased, the volumetric proportion of carbon-rich gas in the stream being held constant throughout nitrocarburisation. …<??>This results in outstandingly wear-resistant and low-porosity surface layers, and corrosion resistance can be further improved by oxidation in humidified air following nitrocarburisation.

Patent GB-2238927-A (GB)
Title: Image processing
Inventor: MITA YOSHINOBU
IPC: H04N1/60
Filed: 1990-09-04
Abstract: When image data is reduced by using only the most significant bit or bits for each pixel density value. e.g. a `"1" or a "0" over the whole 256 levels represented by an 8-bit density value, there is a need to convert the reduced bit values to values having higher numbers of bits, for example when performing colour processes such as masking. Therefore such processing is accomplished by taking into account the values in a pixel window (e.g. 5x5 about a central pixel in question), and performing the processing so as to arrive at a processed value having a greater number of bits. Thus the value of the central 1-bit pixel may be converted to its 8-bit equivalent (equivalent value) and corrected with an 8-bit value derived according to the count of the "1"s in the window (smoothed value). In a subsequent masking operation in which masking matrix calculation is performed, the value of a masked component is derived using the equivalent value thereof and the smoothed values of the other two components. <IMAGE>

Title: Laser feedback control circuit.
Inventor: JOHNSON KEITH ROBERT
IPC: H01S3/094
Filed: 1992-04-21
Abstract: A feedback circuit, comprising: means for producing from a semiconductor laser light output a feedback signal which is representative of the noise and frequency dependent output intensity of the laser light output; means for applying a phase shift to the feedback signal; means for converting the feedback signal to a level signal which is representative of the noise in the laser light output; amplifying means for amplifying the phase shifted feedback signal as a function of the level signal to produce a current gain signal; and means for superimposing the current gain signal on the current flowing through the laser diode. As shown, laser diode 10 pumps solid state laser 9 the light from which is detected by photodiode 30 from which a feedback signal is produced by frequency dependent amplifier 32. Phase shifter 36 provides a frequency dependent phase shift to the feedback signal without introducing additional gain. The noise-output signal from amplifier 32 is also converted to a DC signal VRMS in converter 34 and a servo 40 sums and amplifies this DC signal and a reference signal VREF from 38. Finally multiplier 42 produces an output current signal that is a function of the product of the signals from servo 40 and phase shifter 36 for adding to the laser diode current from supply 12 whereby the amplitude noise in the laser light output is reduced. As disclosed, Fig. 4 (not shown) the feedback noise reduction circuit is formed on a flexible circuit board that is bent to fit and be mounted inside the laser head. <IMAGE>
