Patent GB-2472249-A (GB)
Title: Noise cancelling in a wireless receiver
Inventor: KARLSSON MAGNUS KARL-OLOF
IPC: H04B1/10
Filed: 2009-07-31
Abstract: A wireless receiver for receiving a signal with a characteristic pattern includes a predictor for predicting the presence of a non-zero value of the characteristic pattern. A tracker tracks a noise component in the received signal between predicted non-zero values. The resulting noise component is subtracted from the received signal to output a processed signal, which is then decoded by a pattern discriminator and demodulator. The wireless receiver is less sensitive to noise and interference. This noise cancelling is particularly suited to power saving receivers which are turned on only when there is a signal to be received.

Title: Improvements in or relating to the polymerisation of olefines
IPC: C07C2/20
Filed: 1936-04-04
Abstract: In the polymerization of olefines by a process giving a mixture of polymers of higher and lower boiling point, a desired component is preferentially produced by the use as catalysts of acids of phosphorus or their acid esters or of compounds of boron fluoride containing a hydrogen atom removable by dissociation or compounds of boron fluoride with ethers, and by working in the presence of an added amount of a component whose formation is to be suppressed or, when the desired component is of lower boiling point, by continuously removing the same by distillation at a temperature and pressure such that the higher boiling component remains in the reaction zone.  In examples: (1) propene is polymerized with phosphoric acid at 180 DEG C. and 20 atm. excess pressure in the presence of added isononene to give a product which is largely isododecene, or (2) in the presence of isododecene giving mainly isononene; (3) isobutene is treated with phosphoric acid at 80 DEG  C. and 2 atm. in the presence of added tri-isobutene giving mainly di-isobutene; (4) isobutene-containing gas is treated with phosphoric acid at 150 DEG  C. and 9 atm., di-isobutene being continuously distilled off and non-polymerizable gases allowed to escape.  Di-isobutene is the chief product, minor amounts of tri-isobutene and higher polymers remaining as residue; (5) propene-containing gas is similarly converted to isononene when working at 180--200 DEG  C., minor quantities of higher polymers such as isodedecene remaining.  Specifications 314,932, 447,973, and 453,854 are referred to.  The Provisional Specification is not limited to the use of the catalysts specified, and includes a further example in which an enriched coke oven gas containing propene and butene is treated with phosphoric acid at 170 DEG  C. and 10--15 atm. excess pressure, the low boiling polymer being removed as formed.

Abstract: 553,670. Pneumatic conveyers. WOODWARD, J. C., and BARNES ENGINEERING (PTY.), Ltd. Aug. 7, 1941, No. 10034. Convention date, July 15, 1940. [Class 78 (i)] [Also in Group XXIII] Apparatus for introducing solid particles - directly into a delivery line traversed by steam or air comprises a cell 13 from which charges of sand or other material - are delivered intermittently into a constant pressure chamber 16 from which the material is driven continuously into an ejection chamber 20. The chamber 16, cell 13, and a surmounting hopper 10 are built up of truncated cones, and are connected through bell plugs 25, 26 manually controlled through airtight bearings by handles 25e, 26e. A pressure line 21 supplies fluid through valves 22, '22a, and 22b respectively to the cell 13, chamber 16 and ejector nozzle 23b. In the chamber 16 is a vertical shaft 28 carrying vanes 28a and scraper vanes 28b, together with a metal helix 28c. In operation a release valve 24 is opened to bring the pressure in the cell 13 down to atmospheric, the plug 25 is lowered to admit a charge of material to the cell, and then raised to seal it hermetically. Air or steam under pressure is then admitted by the valve 22 and the plug 26 is lowered. This allows the material to be blown into the chamber 16, the valve 22a of which is constantly open. The plug 26 is subsequently raised, and the process of reducing pressure, admitting material, and raising pressure in the cell 13 is repeated. The gearing 27b, 27c for the shaft 28 is enclosed in dusttight casings 29, 30 and the vanes &c. on the shaft drive the material down through a distance piece 17 to the ejection chamber 20. The piece 17, together with a replaceable nose 18 within it, may be in two parts to facilitate replacement, and an inspection &c. plate may be provided. Between the piece 17 and the chamber 20 may be interposed a booster consisting of a power-rotated bucket wheel into the moving top bucket of which the material is fed and from the moving bottom bucket of which it is driven into the chamber 20 with the aid of an axially fed blast.

Title: Improvements in transmission systems for high frequency electric signals
IPC: H04B3/10
Filed: 1939-03-31
Abstract: 527,104. Transmission systems ; retardation lines. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1939, No. 10117. Convention date, April 23, 1938. [Class 40 (iv)] [Also in Group XL] In a system of the kind in which the lower frequencies of a television or other broad band are transposed to a position above the original upper limit of the band, the low frequency currents are eliminated from the portion of the band that is to be transmitted without change by balancing them against identical currents of opposite phase. As shown, the original currents divide at V, Fig. 7, the lower path comprising a filter 1 which passes frequencies up to 60 kc. without attenuation or phase distortion and cuts off at 200 kc. The low-frequency currents then divide, a portion passing to a modulator 2 for transposing them to a position outside the original band and another portion to a phase-reversing valve 3 to enable them to balance out the corresponding frequencies on the upper path. This path in addition to valves 4 and 5 comprises a retardation network 6, which introduces a phase lag equal to that introduced by the filter 1 in the lower path, and a filter 12 for eliminating frequencies in the shifted range of the lower frequency sub-band. At the receiving end, Fig. 17, the signals are amplified at 13 and then divide, passing respectively to valves 14 and 15 the amplification of which is adjustable. Signals in the lower path are limited by a band-pass filter 16 to the shifted range of the lower frequencies and are amplified at 17, rectified by a double diode 18 and passed via a low-pass filter 19 to individual and common amplifiers 20, 24. Signals, in the upper path after amplification at 14, 25 traverse a filter 21 which eliminates the shifted band of the lower frequencies and a retardation line 22 for equalizing the transmission time of the two branches before passing to individual and common amplifiers 23. 24. Retardation lines. The network 6 which introduces a constant delay for all frequencies preferably includes negative shunt inductance which is provided by mutual inductance between adjacent sections and may comprise a uniform winding on a magnetic or non-magnetic core with tappings at regular intervals for the condensers. As shown in Fig. 15, the condensers may be replaced by the distributed capacity of the windings by using a partially conducting coil support. The Specification includes a discussion of the design of the network and its termination.

Abstract: 1,173,534. Honing. P. NAGEL. 4 March, 1967, No. 10359/67. Heading B3D. A feed arrangement for honing - machines comprises a pressure rod for expanding a honing tool, the pressure rod being connected to an hydraulic piston drive which has a pressure control monitor responsive to pressure in a pump conduit leading to a thrust space of the hydraulic piston drive controlling an electric control means, said pressure control monitor being able to interrupt the pump delivery into the piston drive thrust space by switching over an electromagnetically-operated control valve by closing the electric control switch after rapid expansion of the honing tool has ended in the contact of the honing stones against the wall of a workpiece bore, said switching simultaneously controlling a piston dosaging device which may be controlled by time responsive means, the piston dosaging device being adapted to displace intermittently into the thrust space of the piston drive small partial quantities of fluid from the conduit upstream of the dosaging device to thereby activate the piston drive. A pump 1 delivers, at a pressure determined by a valve 14, to an electromagneticallyoperated valve 6 connected by conduits 7, 8 to the feed and return chambers 9, 10 of a feed cylinder 11 having a piston 13 connected to a presser rod 12 which expands the honing tool. The conduit 7 is connected to a pressure monitor 17 operating a switch 18. A dosaging device in the conduit 7 comprises a piston 16 in a cylinder 15 having an inlet port 20 and a non-return valve 21; upstream of the dosaging device the conduit 7 contains a storage loop 22. A pump 2 delivers, at a pressure determined by a valve 26, to a valve 28 electromagneticallyoperated under the control of a timer 34. The valve is connected by a conduit 29 to a cylinder 31 containing a piston 32 actuating the dosaging piston 16 against a return spring 33. For rotary adjustment of the dosaging piston 16 which has a chamfer 23, the piston slides in a pinion 36 meshing with a rack 35 movable by an electromagnet 37 against a return spring 38, the initial position of the rack being determined by an adjustable stop screw 39.
