Title: Symbol interleaver which checks read and write address validity against variable number of sub-carriers for DVB/cable
Inventor: ATUNGSIRI SAMUEL ASANBENG
IPC: H04J11/00
Filed: 2008-06-11
Abstract: The DVB-T2 standard has several operating modes which have different numbers (0.5-32k approx) of sub-carriers in the OFDM symbols, and systems can switch between modes. The systems interleave symbols on to sub-carriers and in order to minimise memory requirements operate a system wherein symbols for one time period are written into the memory locations where a symbol for the previous time period has just been read. Therefore symbols alternate between being written sequentially and then read out in a pseudo random order, and being written in the pseudo random order and read sequentiallys8. When systems switch modes the quantity of sub-carriers and therefore the use of the interleaver memory changes. The invention checks memory addresses generated against the mode of both the symbol being read outs10/12and the symbol being written ins22/24and only performs the read/write operation at the address if it is valid for the symbol mode. The system is also applicable to cable TV installations.

Title: Detachable swivel lock for a pair of trolley castors
Inventor: BLIGNAUT MICHAEL JOHN
IPC: B60B33/02
Filed: 2009-02-06
Abstract: The swivelling of a pair of trolley castors 14 is prevented by the use of a linkage 10 which is detachably secured to the castors 14 to retain them in a fixed alignment relative to one another. The linkage takes the form of a crossbar 12 having a slotted bracket 11 at each end. When it is desired to restrict swivelling of the castors 14, the brackets are slid over the side plates 16 of the castor forks thereby keeping the castors aligned and locked against swivelling. The crossbar 12 of the connecting linkage 10 may be telescopic, and may be secured to the castors by magnets. When use of the trolley is at an end, the user draws the crossbar 12 away to disengage the brackets 11 from the castors. The cross bar can then be telescoped inwards and stowed in, for example, a shopping bag. The linkage 10 can be used with any trolley such as a shopping trolley or a luggage trolley.

Title: Quartz crystal pressure and temperature sensor with dynamic temperature correction
Inventor: GODAGER OIVIND
IPC: G01L9/00
Filed: 2009-12-04
Abstract: A quartz transducer assembly has four or more crystal-controlled oscillators 2,3,4,5 intended for measurement of applied pressure and temperature. All four oscillators are controlled by crystal quartz resonators 19,20,21,22 operating in the thickness-shear mode. Two crystals measure the pressure and temperature respectively. A third crystal is a reference and the fourth may be another reference or a second temperature crystal. The output of the latter is either phase leading or phase lagging the thermal response of the main temperature sensor. The arrangement of transducers provides a differential temperature measurement and thus a means of feed-forward dynamic correction for fast and accurate pressure and temperature measurements under non-static conditions. The assembly is suitable for downhole use.

Title: Spark ignition systems
Inventor: PHILLIPS BRIAN LESLIE
IPC: F02P3/08
Filed: 1965-03-10
Abstract: 1,108,511. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. March 3, 1966 [March 10, 1965], No.10113/65. Heading F1B. An ignition system includes a capacitor 37 discharge of which produces a spark, switch means 35 in circuit with the capacitor, means operable when a spark is required for turning the switch means on to permit discharge of the capacitor through the switch means to produce the spark, the switch means being turned off when the capacitor has discharged, an oscillating circuit which is turned on when the switch means is turned on, means whereby the circuit charges the capacitor so that for each cycle of operation of the circuit the charge of the capacitor increases and means for stopping operation of the circuit before the next spark is required. When a positive pulse is received at the terminal 38 it switches on the controlled rectifier 35 and the capacitor 37 discharges through the winding 33 and the rectifier 35. When the capacitor has discharged the oscillations caused by the capacitor 37 and winding 33 switch off the rectifier 35. The pulse at the terminal 38 also renders the transistor 16 conductive and current is fed back to the base of the transistor 16 by the winding 18. The oscillator continues to operate even when the pulse is removed from the terminal 38. Each time the oscillator operates current from the winding 13 flows through the diode 34 into the capacitor 37. When the charge on the capacitor 37 reaches the predetermined value the Zener diode 23 conducts and renders the transistor 22 conductive which short-circuits the base emitter terminals of the transistor 16 so that the oscillator stops operating. In a modification the base of the transistor 22 is connected through a resistor to the emitter of the transistor 16 which in turn is connected to the line 12 through a resistor. The Zener diode 23 may be replaced by a four layer diode.
