Patent GB-2040128-A (GB)
Title: Improvements in and relating to signal processing circuits
IPC: H03L7/07
Filed: 1979-12-11
Abstract: Circuits are described for distinguishing between coherent and incoherent energy (e.g. between a signal and noise). One such circuit includes two phase-locked loops (26A, 26B) which are fed in parallel from an input signal F1 at 10 e.g. the IF signal of a superheterodyne receiver. The outputs of the VCO's (30A and 30B) in the loops are fed to a further phase comparator (37) which produces an output only when the input F1 contains coherent energy which enables the loops to lock their VCO's. A threshold level sensor (50) detects the d.c. output from the final phase comparator (37). For an input signal with a poor signal to noise ratio the phase lock loops are subject to 'statistical' lock and the circuit output at 51 varies between a maximum value and a minimum value in dependence on the signal to noise ratio. Loop operation is enhanced by down converting the input signal. The phase locked loops may be replaced by suitable coherent detector circuits. <IMAGE>

Title: Transfer sheet for electrostatic photography
IPC: D21H17/37
Filed: 1979-04-05
Abstract: Copolymer comprising a major amount of hydrophobic monomer such as acrylic ester, methacrylic acid ester, aromatic vinyl and vinyl cyanide, and a minor amount of hydrophilic monomer such as acrylic acid and methacrylic acid is stably dispersed in water without the aid of emulsifier. The aqueous dispersion of this copolymer is coated on paper to provide a transfer sheet having better affinity to toner particles, compared to plain paper sheet, when used in wet-type and dry-type electrostatic photographies, thereby providing images of high quality. Polyethyleneimine or polyepoxy compounds may be added to the aqueous dispersion to crosslink the copolymer, thus resulting in the improvement of transfer heet characteristics for copying. To be more effective in writing quality, polyacrylamide is added.

Title: A combination microwave and convection oven
IPC: H05B6/80
Filed: 1980-01-16
Abstract: A microwave convection oven has a gas burner 90 positioned outside the oven cavity 12. Combustion products are circulated through the oven 12 through screens 16 and 18 for preventing escape of the microwave energy from the oven cavity 12. The burner 90 is the multi-portion ribbon type providing a high burner density and having secondary air closely adjacent to all portions of the burner, to reduce its incandescent flame length while permitting the burner to be positioned in a region between the screened vapour outlet region 18 and the inlet 66 of a blower system. The blower system 64 is used for mixing the output of the burner 90 with the vapour drawn from the oven 12; thus the temperature of the vapour outlet region 20 is maintained below that at which ionization of the vapour being drawn from the oven 12 might produce leakage of microwave energy through the screen 18. The burner is controlled by a temperature sensor 178 responsive to the oven vapour temperature. A temperature probe 150 stuck into the food body 32 signals when the body has reached a preset temperature and/or turns off the microwave generator 54. <IMAGE>

Title: A process for the controlled combustion of solid fossil fuel
IPC: F23N5/18
Filed: 1981-06-22
Abstract: In this process the fuel, such as coal dust, and combustion air are fed to a combustion chamber 1 via individual burners 2 having single flames 3 associated therewith. The intensity of radiation of each of the flames 3 is monitored by three radiation detectors 4 of which one is allotted to the base of the flame 3, one to the main combustion zone and one to the top of the flame 3. The supply of fuel and/or combustion air to the individual burners 2 is controlled as a function of the measured intensity of radiation of the flames 3 associated with the individual burners 2. In this way variations in the quality of fuel or incorrect supply of fuel and/or combustion air can be rapidly compensated for, so that the installation does not have to be operated with an excess of air and the emission of waste gases is minimised. <IMAGE>

Patent GB-2109654-A (GB)
Title: Apparatus for transferring data between two positions
Inventor: STEPHENS PHILIP EDWARD
IPC: H04B10/85
Filed: 1981-11-06
Abstract: Data from a computer 1 and from a spurious signal generator 3 is switched at 4 between lines 4A and 4B before being converted to optical form at 6A and 6B. The two channels of optical signals 7A and 7B are multiplexed onto a common line 8 to a demultiplexer 9. The outputs of the demultiplexer are converted back to electrical form at 10A and 10B and a switch 11, acting in synchronism with switch 4, separates the data from the spurious signals. The data is fed to a second computer 2. Because the line 8 is an optical line it is difficult to tap and this is made even more difficult by the presence of the spurious signals. In this way the invention makes it possible to reduce problems previously encountered in monitoring security of information transmitted between computers located at different positions. <IMAGE>

Title: Deceleration-sensing modulator valve assembly for vehicle braking systems
Inventor: MORTIMER IVAN
IPC: B60T8/28
Filed: 1981-12-02
Abstract: In one construction, Figure 1, a deceleration sensing ball (17) is housed in a cage (18) which is resiliently biassed towards a step (19) in the housing (1) and towards a shoulder (23) on a control piston (9) by a spring (20). A valve seat (15) is provided on the control piston at one end of a piston passage (16) that normally connects the inlet port (7) connected to a master cylinder with outlet port (8) connected to the rear wheel brakes. A pressure effective area (A1) of the control piston normally subject to inlet pressure is slightly less than an oppositely acting pressure effective area (A2) subject at all times to outlet pressure. When the ball (17) engages with the valve seat (15) due to excessive deceleration a further rise in inlet pressure urges the piston towards the outlet, and the ball is unseated from the seat (15) by a lip (22) on the cage, to produce a step in the output characteristic. An arrangement (Figure 4) for use with a dual circuit system, one circuit supplying the front wheels and the other circuit supplying the rear wheels through the modulator valve assembly. <IMAGE>

Patent GB-2125380-A (GB)
Title: Improvements in or relating to sealable containers
Inventor: BUTLER JOHN NICHOLAS
IPC: B65D43/02
Filed: 1982-08-20
Abstract: A plastics lid is sealed with respect to a container by means of a sealing arrangement including a flange 36, formed on the lid and an internal groove 24 formed in the container at the junction between an upwardly flaring rim wall 12 and a radially outwardly extending ledge which connects the rim wall 12 with the rest of the container. Both the ledge and the flange 36 are frusto- conical, with relatively large apex angles and the flange 36 is connected with the remainder of the lid by an integral flexhinge 38. The arrangement is such that the lid can be applied to and removed from the container opening by vertical movement and that during such vertical movement of the lid towards a closed position, the flange 36 abuts the ledge, and is flexed about the hinge 38 from a position in which it is inclined towards the ledge, through a dead centre position, to an over-dead- centre position in which it is inclined in the opposite direction and lies against the ledge. The free edge of the flange 36, in the dead centre and over-dead centre positions, is urged resiliently into sealing engagement with the groove 24, and the ledge limits movement of the flange 36 past its over-dead-centre position. <IMAGE>
