Patent GB-2237708-A (GB)
Title: Radio transmission of digital data
Inventor: REDDING ROBERT JAMES
IPC: H04L27/12
Filed: 1990-10-11
Abstract: Digital serial data streams are transmitted by shifting the frequency of a radio frequency carrier at each change in the data stream and the carrier is radiated either directly or after amplification. The rate of change of frequency and its direction comprises the transmitted intelligence. The sidebands in the transmitted radiation are reduced by the substantial absence of inductive elements in the associated circuits. Preferably the digital information is fed to a semiconductor switch which connects a capacitor or resistor into the frequency determining network of an oscillator 4 which comprises the carrier either directly or after amplification or frequency multiplication or division; the capacitor or resistor may be switched by means of a series connected transistor 3. For increase in the radiated carrier power the output from the oscillator may be fed to a linear amplifier 14 connected to an aerial 13. <IMAGE>

Title: A method of separation of mixtures of gases by alternating pressure adsorption
Inventor: MAASSE HANS-JURGEN
IPC: B01D53/047
Filed: 1990-10-19
Abstract: A method of separation of mixtures of gases by alternating pressure adsorption. In the adsorptive separation of mixtures of gases particularly the recovery of oxygen from the air, upon conclusion of the adsorption process, there is a two-stage reduction in the pressure of the charged adsorber 1. In the first stage, an equalisation of pressures is carried out with the second adsorber 2 through the outlet ends of the two adsorbers by opening valves 17, 18. In the second stage of pressure reduction valve 18 is closed and valves 9, 11 and 19 are opened. There is a bilateral relieving of the charged adsorber simultaneously through an inlet and an outlet end until ambient pressure is reached. The gas which flows thereby through the outlet end of this adsorber is guided into a third adsorber 3 via its outlet end and is used to scavenge this adsorber. The gas flowing out at the same time from the inlet end of the charged adsorber is removed through residual gas line 8. <IMAGE>

Title: Secretion vector
Inventor: DAS GOUTAM
IPC: C07K14/62
Filed: 1991-01-17
Abstract: In this patent application we have described the construction of a novel secretion vector based on E.coli enterotoxin coding sequence. We have shown categorically that pre and pro region of toxin gene are absolutely necessary for extracellular secretion of the stable toxin. We have also shown with specific examples that when the nucleotide coding sequence of a heterologous peptide is fused in frame to the end of the pro region in the st gene, the resultant vector in an E.coli host secretes extracellularly correctly processed heterologous peptide. This application also includes construction of suitable vectors where this gene fusion can be achieved. General methods to create such fusions involving a) recombinant DNA technology and b) the use of site directed in vitro mutagenesis, have also been described. A general method of purification of heterologous peptides is also described in this application. This novel vector system can be used for hyperproduction and extracellular secretion of peptides of biological importance.

Patent GB-2248470-A (GB)
Title: Draught biased aperture flap
Inventor: JESSEL RICHARD VICTOR
IPC: A47G29/126
Filed: 1991-03-20
Abstract: A letter box flap mechanism that does not rely on springs, magnets, or catches, to prevent it from blowing open. Rather than blow open it will blow closed. This is because the pivot point is below the centre of the surface area on the front of the flap, and rear of the flap has the largest surface area below the pivoting point. In the absence of wind, the flap will close by gravity, because the weight of material below the pivot, is greater than the weight of material above the pivot. Although the pivot point is near the centre of the opening, as soon as the flap opens, it can be lifted up to the top of the aperture, allowing unrestricted use of the total opening. On releasing, the flap drops to the pivoting points, then rotates shut, purely by gravity.

Patent GB-2261976-A (GB)
Title: Vehicle road safety device
Inventor: BENNETT JOHN FREDERICK
IPC: G01S17/931
Filed: 1991-11-27
Abstract: A transmitting device, using e.g. an infra-red light beam, is connected to a vehicle so that the speed of the vehicle determines the strength of the beam transmitted, such that the beam covers the recommended safe braking distance for the speed generating it. In response to the windscreen wipers being operated (but not the intermittent screen wash) the strength of the transmitted beam is adjusted such that it covers the recommended safe braking distance for wet conditions. Any other vehicle within range of the said beam (forward or behind and with suitable receptors) causes the completion of an electrical circuit in the transmitting vehicle to produce a visual/audio warning to the driver of the transmitting vehicle.

Title: Event driven programmer logic controller
Inventor: BURSHTEIN ANAT
IPC: G05B19/05
Filed: 1994-08-16
Abstract: In a processor arrangement having a programmer logic controller (PLC) operating to a ladder diagram process, a number of event inputs 11 - 15 are provided connected to an interrupt buffer 31, in turn connected to a real time clock 32, for recording times of events of signals received on the event inputs and generating interrupts. Sequential storage locations in a cyclical buffer 60 store interrupts and their event times, where events occurring within a predetermined incremental time window are stored, with their event times, in a storage location for that time window. Each location of the cyclical buffer is inspected in sequence upon each new step of the sequential process. The PLC is arranged to operate on any events stored in the buffer which are affected by the new step of the sequential process before proceeding to the next step of the sequential process. Resolution is thus improved with the detection of changes of the inputs not being affected by controller accuracy or scan time. <IMAGE>

Title: An electronic control system for an engine and the method thereof
Inventor: MORIKAWA KOJI
IPC: F02D21/08
Filed: 1994-12-13
Abstract: The air-fuel ratio of a lean-burn engine (1) is controlled so as to be adjusted to a lean-burn air-fuel ratio with a low NOx concentration. As this is done, an actual combustion fluctuating rate is detected from the cylinder pressure, and the air-fuel ratio is adjusted to the rich side with respect to the lean-side limit, whereby a satisfactory driving performance can be secured. The state of NOx exhaust is determined by an actual NOx concentration, and the air-fuel ratio is adjusted to the lean side with respect to the allowable limit of the NOx exhaust. On the other hand, the combustion fluctuating rate and an allowable limit value of the combustion changing rate under the driving conditions concerned are compared, while the NOx exhaust rate and an allowable limit value of the NOx exhaust rate under the same driving conditions are compared. The EGR amount is decreased when the combustion fluctuating rate is higher than the allowable limit value, and is increased when the NOx exhaust rate is higher than the allowable limit value of the NOx exhaust rate. Thus, the NOx exhaust can be decreased. <IMAGE>
