Title: Greatly enhanced spatial detection of optical backscatter for sensor applications
Inventor: EVERARD DR JEREMY KENNETH ARTH
IPC: G01D5/353
Filed: 1986-05-09
Abstract: A pseudo random bit sequence is amplitude modulated onto a light source (2) (other types of modulation are discussed in the specification) and this modulated beam is transmitted down an optical fibre (3) or any material and the detected backscatted signal is multiplied (9) with a digitally delayed reference version of the transmitted sequence. By varying the delay between the transmitted and the reference pseudo random sequence spatial information can be recovered with improved signal to noise ratios compared to conventional Optical Time Domain Reflectometry. This enables improvements in the detected signal to noise ratio of the backscatter allowing reduced signal averaging times or reduced peak transmitted power. This technique can be used to produce enhanced optical sensors, sensing any external parameter on which the backscatter is dependent using video, and coherent detection. Enhanced fibre loss measurement techniques and enhanced fibre discontinuity measurement techniques are described. Distributed temperature sensors are described using Billouin and Raman backscatter. Because of enhanced detection the spatial resolution for a given signal averaging time can be reduced. The measurement of the amplitude, spectra, phase and polarisation of the scatter can also be used to characterise the properties of the material and the influence of any external parameters which influence the properties of the materials producing the backscatter. The measurement of backscatter can therefore be used to measure any external measurand which influences the amplitude, frequency, phase and polarisation of the backscatter.

The signal driver may include a shift register 31, a latch 32 and a grey scale control circuit 33 which controls the pulse width in dependence upon the period of a grey scale clock CLK. For obtaining optimum grey scale characteristics that matches the reflectivity characteristics of the LC device either the period of the grey scale clock CLK may be adjusted or a suitable code - conversion circuit may be provided before the shift-register 31. Circuits 37, 34 control the voltage levels of the scan, data pulses. <IMAGE>

Abstract: Manufacture of an article 1 incorporating a thermosetting-powder surface-coating 2 includes bonding a component 4 of the article to the coating 2 by contacting the melted powder with the component 4 before curing takes place, and maintaining it in contact through curing (Figure 2). In a glass architectural panel, an aluminium foil 4 is bonded in this way to a polyester/triglycidyl-isocyanurate powder coating 2 on the silane-primed back of the facing glass 1; the metal foil 4 is backed by a plastics or rubber open-cell material 5 to enhance resistance of the glass 1 to impact, and also, together with the foil 4, resistance to thermal shock. The coating 2 includes pigmentation to give the effect of coloured glass, or is clear to allow the contact-surface of the foil 4 to show through; further decorative effect 26 is obtained by pigmentation variation in the coating 25 and/or partial metallization of the glass back-surface (Figure 3). The technique is also applied to bonding fittings 29 to the powder-coated face 27 of a door 28 (Figure 4); of decals 33 of cured powder-coating material to (or within) a powder-coating 35 (Figure 5); of glass 36 over apertures in metal walls 38 (Figure 6); and of glass 41 to glass 42 in building up a laminate (Figure 7).

Title: A hydraulic dual-circuit braking system
Inventor: STEGMAIER ALWIN
IPC: B60T8/34
Filed: 1991-04-26
Abstract: A hydraulic dual-circuit vehicle braking system having anti-skid (ABS) and drive slip (ASR) control has control valve arrangements (21-24) and a return pump (20) with elements (25, 26) for each brake circuit. During an ASR operation, a pre-charging pump (38) supplies fluid from a brake fluid reservoir (18) into the pump element (25) associated with the brake circuit of the drive wheels (11-12), while the valve unit (39) separates the pump element (25) from the master cylinder (16), and connects it by way of a pressure-limiting valve (46) to the reservoir (18). A non-return valve (45) prevents brake fluid flowing by way of the pressure-limiting valve (46) back into the ABS brake circuit. The air bubbles that occur on expansion of the brake fluid at the pressure-limiting valve (46) pass, together with the excess brake fluid, into the reservoir (18) and are thus kept away from the master cylinder (15). A modified system with a diagonal connection has a second valve (42) for the other circuit. <IMAGE>

Abstract: A rocker arm 14 operated by a high speed cam (4b, Fig. 2) is mounted to rock on a common shaft 10 between a pair of valve-operating rocker arms (9) connected by a shaft 12 and operated by respective low speed cams (4a). A pair of pins 16, slid able by oil pressure to project from respective side-by-side bores 14d in the arm 14, have flat faces 16c engageable with the shaft 12 so that the high speed cam operates the valve-operating rocker arms. Each pin 16 is prevented from rotating in its bore 14d by a plate 17b on a plug 17c closing the pressure chamber 14e and engaging a slot in the pin or by a pin (16c, Figs. 7 and 8) engaging the pin face 16c which also limits the pin outward movement. <IMAGE>

Title: Thermodynamic apparatus.
Inventor: ENSLIN JOHAN ADAM
IPC: F01C7/00
Filed: 1992-08-28
Abstract: Thermodynamic apparatus 12 of cylindrical shape has a boiler 14 at one end to provide vapour at high pressure and temperature, and a condenser 16 at an opposed end to condense spent vapour. A rotor 30, rotatable about axis 34, has concentric annular partitions 42 forming annular chambers 44. Longitudinal and radial partitions (46, Fig 4) divide the annular chambers into sub-chambers (48), which have open radial extremities to form condensate ports. A drum 50 around the rotor freely rotates in sympathy with the rotor about axis 52 parallel to and spaced from axis 34 and supports a condensate jacket 66. Due to eccentricity, condensate cyclically moves into and out of sub-chambers respectively to contract and expand each sub-chamber. Valve means directs vapour into sub-chambers of the first annular chamber while they expand. The vapour expands against and pressure. When a sub-chamber contracts, the valve the condensate to do useful work while transferring heat means conducts vapour therefrom to a diametrically opposed expanding sub-chamber of a subsequent annular chamber. Vapour passes from the boiler to the condenser and condensate passes from the condenser to the boiler via the annular chambers. <IMAGE>
