Title: Improvements in or relating to ground effect machines
Inventor: BERTIN JEAN HENRI
IPC: B60V3/04
Filed: 1969-10-10
Abstract: 1286127 Gas-cushion vehicle BERTIN & CIE 10 Oct 1969 [10 Oct 1968] 49978/69 Heading B7K A gas-cushion vehicle, particularly one guided by fixed tracks, is provided with means for varying a barrier at the front of a gas cushion to counteract increasing inrush of ambient air as the speed of the vehicle increases. Gas cushion 9 is bounded at the front by a fixed vertical wall 16 which bears a further wall 17 pivoted at 18 such that when the wall 17 is vertical it extends below the wall 16. When the vehicle is at rest the wall 17 is held against stop 21 by spring 19, but as the speed of the vehicle increases cushion pressure will increase, tending to turn the wall 17 clockwise (as viewed in Fig. 2) so as to reduce the gap beneath the wall 17, and this will prevail over the increasing ram air pressure. In a similar construction, Fig. 3, wall 25 extends beyond pivot axis 26 into a chamber 28, dividing the chamber into two parts. That part to the rear of the wall 25 is connected by a duet 31 to air intake 3 of the vehicle, so that with increasing speed of the vehicle the pressure in that part is progressively reduced, tending to counteract the torque on the wall 25 caused by ram air pressure. Alternatively, Fig. 6, the inrush of air into the cushion space may be controlled by a fluid curtain, issuing from a nozzle 41 formed by front wall 39, curtain thickness increasing with the speed of the vehicle. This may be achieved by feeding the nozzle 41 from an air intake 47 at the front of the vehicle, or by feeding it from a compressor (45, Fig. 7, not shown) whose power supply is governed by a rheostat (47) controlled by a piston (51) which is pushed progressively backwards by ram air against a spring (52) as the speed of the vehicle increases.

Title: Pulser for modulated beam tubes
IPC: H01J31/02
Filed: 1963-12-18
Abstract: 1,055,095. Keying radio frequencies. VARIAN ASSOCIATES. Dec. 18, 1963 [Dec. 31, 1962], No. 50074/63. Heading H3R. The beam of a kylstron or like tube 24 is keyed by " on " and " off " pulses applied over transformers 29, 33, respectively, to render associated diodes 27, 31 conducting. The diodes are connected respectively between the cathode 19 and modulator anode 21 and between the modulator and accelerating anode 23. The " on " pulse switches on the beam by raising the potential of the modulating anode 21 to that of the anode 23 (determined by source 25) and discharges the interelectrode capacitance 39, and the modulator anode potential remains at this value until the "off" pulse reduces it to that of the cathode 19 to switch off the beam and at the same time discharge interelectrode capacitance 37. A leakage resistor 35 is preferably provided normally to hold the modulator anode at cathode potential, and external capacitance may be provided in parallel with 37 to control the pulse shape of the beam.

Abstract: 1523307 Signal controlled threshold circuits ASTON ELECTRONIC DEVELOPMENTS Ltd 9 Dec 1976 [9 Dec 1975 12 Feb 1976] 50366/75 and 5584/76 Heading H3T A data signal in the form of a burst of clock pulses followed by a sequence of data pulses is thresholded by detecting the presence of the clock pulses, generating a sample pulse during the time the clock pulses are present establishing the mean level of the clock pulses, using the sampling pulse to sample and hold the mean level of the clock pulse and using the held level as threshold for the data pulses. As described, the invention is applied to teletext data on a video signal and the sample pulse generator 43, Fig. 6, which may comprise monostable multivibrators, delays the sample pulse to near the end of the clock pulse burst to ensure that the mean level of the clock pulses has been established by the low-pass filter 45. The low pass filter may be replaced by a delay circuit and a mixer which combines the input signal directly and after a delay equal to half the clock pulse period.

Abstract: 990,723. Fusible cut-outs. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 31. 1963 [Jan. 18, 1963], No. 51281/63. Heading H2G. A fuse comprises a tube structure having a central passage with a vent between its ends, and a pair of movable arcing rods disposed in said passage in end-to-end relationship, connected together by a fusible member and biased away from each other so that when fusion occurs, the arcing rods are accelerated away from each other, thus rapidly drawing out the arc. The fusible member comprises a central wire 21, which takes the strain of the spring biased rods 18, and an outer member 22 which is of a lower resistance than the wire 21 and carries most of the current. At one end of the fuse is a rod 30 which moves outwardly with the rod 18 when the fuse blows, the end 30a striking a latch 33 to operate a releasing mechanism which forces the fuse to pivot in a clockwise direction about trunnions associated with the lower hinge assembly 9. This provides a visible indication of fuse operation and additionally furnishes an isolating air gap. Gas-evolving blocks 50 line the passage 53. A condenser 45 may be associated with the vent collecting chamber 40, to de-ionize exhaust gases.

Abstract: 1375733 Seismic signal processing UNITED GEOPHYSICAL CORP 9 Nov 1971 [9 Nov 1970] 52033/71 Heading H4D Digital representations of the earth's subsurface structure, which have been obtained by processing seismic traces and stored in a computer memory, are converted to a digital representation of a synthetic hologram which may be used to present a three-dimensional replica of the structure.  In the embodiment described, traces are first obtained and processed generally as in Specification 1,359,719 (see Division H4) to accumulate a migrated digital "image" of subsurface points P in "subsurface" memory cells of the computer. Cells of a "hologram memory unit" are then assigned on a one-to-one basis with notional points N in a reference surface EL (plane or curved) in a known scale and geometrical relation with the subsurface. For each point P in the subsurface (associated with a respective cell of the subsurface memory) there is computed the amplitude distribution over surface EL for a wavefront from a hypothetical radiation source, at P, of wavelength # and of intensity corresponding to the accumulated trace amplitude in the subsurface memory cell associated with P, Each such distribution is in the form of a Fresnel pattern of rings. Measures of the amplitude values are stored in the appropriate cells of the hologram memory, where the measures for the various overlapping distributions add algebraically to form a digital synthetic hologram. This is converted by a plotter to an optical hologram transparency. The hologram image is reconstructed by directing laser light, of wavelength # through a lens system on to the trans parency, and viewed by placing a diffusing screen or volume of scattering material (e.g. smoke particles in air or particles dispersed in glass) in the image space. If # is in the ultraviolet range the scattering material may be fluorescent. To avoid ghost images or flare effects, broad-band (e.g. F.M.) seismic signals are used when obtaining the original seismic traces, the received seismic signals being correlated conventionally prior to the above digital processing.

Title: Method and apparatus for the discontinuous sampling and proportioning of gases vapours or mixture thereof
IPC: G01N1/00
Filed: 1976-12-14
Abstract: The sampling arrangement is designed, in particular, for gas chromatography. The unreliable determination of the proportions of gas, vapour, liquid and gas dissolved in the liquid is to be avoided. Sampling is carried out discontinuously at temperatures above the dew-point of the material to be sampled, in such a way that no separation takes place of gas and condensate. The sampling column used for sampling has a tube (1) with shut-off elements (2, 3) in the form of slide valves having no dead space. A probe (4) is used to record the material to be sampled. Conical connectors (5, 6) at each end of the tube (1) are used for connection to an analytical instrument. The material to be sampled can be stored in the sampling column and, prior to being dispensed to the analytical instrument, can be reheated to above the dew-point temperature. <IMAGE>
