Patent GB-2000411-A (GB)
Title: Ceilometric method and apparatus
IPC: G01S17/18
Filed: 1978-06-15
Abstract: The total range to be explored consists of a succession of range-steps. For each range-step, a transmitter emits upwards at least one laser pulse, which is reflected downward by clouds onto a range gated receiver. The gating interval is progressively shifted, to run through the range-steps. For each range-step, reflected laser pulses received during the gating intervals, if any, are integrated. The power attenuation of the reflected pulses is an approximately quadratic function of height, the relationship between the range-step value and the integrated signal is thus made approximately quadratic. In the lower part of the total range, the conical beam patterns of transmitter and receiver progressively overlap, to create an overlap which increases quadratically with height. At least in the remaining upper part, an integration schedule is established, fixing for each range-step the number of pulses integrations performed before going onto the next range-step. The number of integrations performed per range-step increases approximately quadratically as a function of range-step value or height. <IMAGE>

Title: A method of roofing
IPC: E04D13/17
Filed: 1978-08-18
Abstract: An existing roof 1, 2 is renovated by laying an air permeable or absorbent layer 3 on the roof, placing ventilators 4 on that layer and then laying a layer of bitumen felt 5, an isolating membrane 6 impermeable to molten asphalt and a layer of molten asphalt 7 to cover the bases of the ventilators. In this way gases produced by algae in the original roof 1, 2 may be vented through the layers. An original roof resistant to blistering and the seepage of water due to cracking can be constructed by interposing an isolating membrane impermeable to molten asphalt between bitumen felt and asphalt. The permeable layer comprises dry laid expanded clay aggregate, and the isolating membrane prevents bitumen from the felt bubbling up into the molten asphalt <IMAGE>

Title: A travelling machine for distributing and profiling the bedding ballast of a railway track
IPC: E01B27/02
Filed: 1979-01-16
Abstract: An on-track machine for distributing and profiling railway ballast has a vertically adjustable ballast- distributing plough assembly 24. This includes a rigid substantially V- shaped central plough 26, a side plough 27 extending obliquely across each rail ahead of the centre plough and arranged to direct ballast towards the centre of the track, and a pivotable baffle plate 32 at the rear end of each side plough and having a length sufficient to extend to the forward tip of the centre plough 26. Thus, by pivoting of the baffle plates 32, the ballast collected by the side ploughs can be guided to one or both sides of the centre plough. Each rail is covered, in the ploughing region, by a tunnel-like cover 28. The baffle plates may be slidable instead of being pivotable relative to the respective side ploughs. <IMAGE>

Title: Fuel vaporizing combustor tube
IPC: F23R3/32
Filed: 1978-12-07
Abstract: A combustor (18) for gas turbines (10) has fuel vaporizing tubes (40) and associated mechanisms. The vaporizing tubes (40) are constructed to maintain uniform temperatures therein and the structure also maintains uniform temperatures in the head plate (44) and splash plate (50) of the combustor (18). The vaporizing tubes (40) have a direction of vapor discharge disposed at an angle (92) from the axis of the tube stem (54) to direct the vapor stream to the side away from the stem base to minimize formation of localized hot spots and prevent head plate (44) and/or splash plate (50) damage. The interior of the vaporizer tubes (40) are smoothly flow contoured to eliminate eddies and flow losses and thereby prevent localized hot spots therewithin. The vapor tubes have non-uniform wall thickness (86, 88) serving to prevent areas of carbon build-up and localized hot spots. The splash plates (50) are designed to act with respect to the discharge flow and reduce the total temperature spread in the head plate (44) and splash plate (50). The splash plate (50) configuration shields the head plate (44) from the hot vapor discharge from the tubes (40). <IMAGE>

Patent GB-2054143-A (GB)
Title: Measurement of the Size of Particles Dispersed in a Fluid
IPC: G01N15/02
Filed: 1980-07-11
Abstract: Measuring the size of particles dispersed in a fluid by setting up interference fringes in a region of the fluid including the particles, measuring simultaneously the maximum intensity of light scattered by the particles and the "fringe visibility", deriving an estimation of the size of the particles from both measurements, and comparing the estimates to derive a calibration factor for carrying out further determinations of the size of the particles by measurement of the intensity of the light scattered by the particles. The "fringe visibility" is the ratio of the peak of the variable component of scattered light to the mean value. The fringes are formed by splitting a green laser beam 31 in prisms 33-38 and recombining the beams at an angle with a lens 40. Backscattered light is detected by photomultiplier 46, while a monitor photomultiplier detects back scattered blue light from fringes produced from another laser line through the same optical system. <IMAGE>

Patent GB-2050630-A (GB)
Title: Method of determining the fatigue threshold value of a material
IPC: G01N3/32
Filed: 1979-08-28
Abstract: When determining the fatigue threshold value of a material, a test specimen (5) manufactured from the material is subjected to a time dependent alternating load (P). The test specimen has a crack notch (1) and the maximum value of the load is chosen so that the crack propagates. By gradually decreasing the maximum value the crack propagation is retarded and will cease at a certain value of the load. The opening of the crack increases successively as the crack propagates. Thus one can gradually decrease the load range during the crack propagation if at the same time the crack opening variation is kept constant. In order to obtain a reproducible fatigue threshold value care is taken to keep the ratio between the minimum and maximum values of the alternating load constant. For each chosen value of said ratio the minimum value of the load will in this way decrease at the same rate as the maximum value of the load decreases.
