Patent GB-2165941-A (GB)
Title: Gas analyser
Inventor: WEBB PETER JOHN
IPC: G01N21/35
Filed: 1984-10-19
Abstract: A gas analyser comprises a source of infrared radiation 12 on one side of a gas duct 10, a chopper 14 and reference samples 20,22 which can be placed in the beam: 20 having the same absorption characteristics as the test gas and 22 transparent in the region of absorption. The radiation reaches detector 30 via selectable narrow band filters 32 and 34. 32 transmits radiation of the absorption band, but 34 eliminates it. Errors, caused for example by alignment of the reference samples, can be corrected by correlating the detector readings through samples 20 and 22 when filter 32 is used, and multiplying the result by a correction factor obtained by comparing the readings obtained through samples 20 and 22 when filter 34 is used. <IMAGE>

Title: Universal joint for a cardan shaft
Inventor: LINDENTHAL HANS
IPC: F16D3/41
Filed: 1985-12-18
Abstract: A spider bearing having a radial bearing and a thrust bearing wherein the inner ring of the radial bearing rests on the outside axial end of the pin through the use of a flange against the end of the pin while another flange, axially disposed from the first, forms the inner race of the thrust bearing. Therefore, axial force is introduced via the end of the pin. The root of the pin, therefore, remains free of slots or joints, and without contact with the inner ring and the thrust bearing, such that upon deformation under load, tilting of the race does not occur. Therefore, parallelism of the thrust bearing races is maintained and uniform load-carrying capacity of the bearing is assured. The spider may, therefore, be shaped more optimally in the region of the root so as to obtain greater strength.

Title: Radar signal receiving and processing device for countermeasures analyzer
Inventor: AGOSTINO PHILIPPE
IPC: G01R23/173
Filed: 1986-02-27
Abstract: The amplitude-frequency spectrum of an input signal can be reproduced as an amplitude-time waveform by mixing (2) the input E with a linear frequency ramp (4) and supplying the difference frequency to a linear dispersive filter 12 whose time-delay/frequency characteristic has a slope matching that of the ramp. To avoid discontinuities at the end of each ramp, the system includes two mixers (2, 3) enabling two multiplications of the input signal to be made in parallel by two linearly frequency modulated frequency ramps, shifted with respect to each other by a duration T. This device also includes, for the processing, means of recognizing the carrier frequency of radar transmissions thus detected, by taking account of the special nature of the output signals of the spectrum analyzer. <IMAGE>

Title: Nuclear magnetic resonance apparatus with switched attenuator
Inventor: WILLARD REGINALD ALFRED
IPC: G01R33/44
Filed: 1986-04-29
Abstract: Nuclear magnetic resonance is excited in surrounding fluids by pulsing a winding 12 which with a capacitor 11 forms a resonant circuit. In order to observe signals induced by NMR in the winding 12 between pulses, the pulses are attenuated by connecting resistors 217 and 218 across a winding 26 inductively coupled to the winding 12. Connection of the resistors is made when required by forward biassing MOSFETs 214 and 215 connected "back to back" to reduce transients when the MOSFETs cease conduction. A switching pulse for the MOSFETs which has a steep rising edge and an exponential trailing edge has been found advantageous. <IMAGE>

Title: Formation density logging using two detectors and sources
Inventor: COOPE DANIEL F
IPC: G01V5/12
Filed: 1986-07-10
Abstract: A gamma ray density sub (10) and method for measurement-while- drilling using a pair of gamma ray sources (22, 24) and detectors (30, 32), located symmetrically about the axis of the sub, and computation of the product of the counting rates obtained from the two detectors to indicate the average density of a formation sample (46) which surrounds a borehole traversing an earth formation (20). The sub is able to measure the density of the sample independent of the location of the sub within the borehole and of the chemical composition of the interfering materials lying between the formation sample and the detectors. A second set of detectors (40, 42) similarly receives scattered rays indicative of density of a second formation sample (47). The product of the count rates of the second detectors is divided into the first product to yield a density indication which is independent of borehole effects. <IMAGE>

Title: Air conditioning systems
Inventor: ATKINSON MICHAEL JOHN
IPC: F25B9/00
Filed: 1989-10-10
Abstract: A compact, air cycle air conditioning system comprising a compressor (14), turbine (26), heat exchanger (18) and high speed electric motor (32) is thermostatically controlled to supply either hot or cold conditioned air to a load air space. Switching between cooling (as shown) and heating modes is implemented using two-way valves (16, 24) such that the same components may be used, and in all embodiments described the conditioned air is supplied from a dry, closed loop. The system may operate in reverse flow i.e. the working air enters the turbine first. Moisture removal devices (28') may be incorporated to avoid heat exchanger icing and also control humidity, in addition, de-icing systems are included in the reverse flow embodiments because of their greater susceptibility to heat exchanger icing due to lower cycle temperatures. The temperature at which air is delivered to the load can be controlled either by diverting controlled amounts of hot or cold air, as appropriate, to be mixed with the conditioned air, or by varying the speed of the drive motor. <IMAGE>
