Patent GB-2194416-A (GB)
Title: A method of authenticating stream ciphers
Inventor: BUCKLEY DAVID DOUGLAS
IPC: H04L9/32
Filed: 1986-08-19
Abstract: A problem associated with any encrypted message occurs when an interceptor attempts to not necessarily cryptanalyse that message, but instead to intercept the ciphertext and to alter it in such a way as to convey an alternative meaning. This may take the form of altering one or more selected bits of the ciphertext stream to invert the meaning of the decrypted plaintext. Accordingly an aim of the present invention is to provide a stream cipher having an authentication code added, but which has a further property of rendering the "known plaintext" cryptanalytic attack useless. A cryptosystem is used to encrypt an authentication message which is added to the plaintext message to provide a pseudo-random output ciphertext message. <IMAGE>

Title: Method and apparatus for examining a gas mixture
Inventor: FRANZEN KATTENTUMER HEERSTRASS
IPC: H01J49/38
Filed: 1986-09-10
Abstract: An apparatus for examining a gas mixture for the presence of at least one particular contaminant comprises a single quistor (quadrupole ion store) having electrodes (1,3,4) defining a chamber (2) which is fed with the gas mixture, in particular contaminated air, via a diaphragm (9) which exhibits greater permeability to the contaminant than to the molecules of the basic substance. In the chamber (2) all the steps of a double mass spectroscopic analysis are carried out successively in time, i.e. ionization of the gas mixture, elimination of all ions which have a mass/charge ratio different from that of the contaminant whose presence is to be determined, subsequent fragmentation of the remaining ions and, finally, mass-spectroscopic analysis of the fragments so obtained. Such an apparatus, which, due to the use of a quistor and a diaphragm for supplying the gas mixture, can do with a pump having a pumping capacity of only 10 l/s at a pressure of 10 mPa, permits contaminants to be detected even if they are present in concentrations as low as 0.01 ppm. <IMAGE>

Patent GB-2210528-A (GB)
Title: Radar
Inventor: MILLWARD JOHN PETER
IPC: G01S13/933
Filed: 1987-09-28
Abstract: A radar system is disclosed in which a ground radar station transmits positional data of detected objects and an aircraft receives the data and displays it on a screen, having firstly transformed the data so that the position of the host aircraft forms the centre of the display. The system therefore acts as if the host aircraft has its own radar apparatus. Because the display in the aircraft is centered on the host aircraft, it is far easier for the pilot to detect whether he is on a collision course with another aircraft than it is for an air traffic controller to detect whether two aircrafts on his screen are on a collision course.
