Patent GB-2094587-A (GB)
Title: Data processing
IPC: G11B5/09
Filed: 1981-03-11
Abstract: Blocks of data, each representing niney-six lines of a digital television signal are subjected to horizontal shuffling (3, 4) within each line and then to vertical shuffling (7, 8) within each block. The effect of the vertical shuffling is to displace sample words to different lines so that in the event of errors occurring during recording and reproduction in a video tape recorder (11), valid sample words are available adjacent to any error sample word for the purpose of error concealment. The vertical shuffling does not interfere with vertical parity generation (10) or with the correction of errors (13, 18) after reproduction using the vertical parity words.

Patent GB-2095796-A (GB)
Title: Control for gas-burning equipment
IPC: G05D23/12
Filed: 1982-03-25
Abstract: A gas control, for use as an oven thermostat comprises a body (1) with a tapered bore and a correspondingly tapered plug (7) rotatable in it. The plug is part of a unitary element (6) which also includes a setting cam (8). Rotation of the element brings ports in the plug and body into and out of register and thus turns the gas supply on and off. One end of an axially movable rod engages the cam, while the other end engages one end of a beam (29) carrying a valve component (32) at its other end. A central part of the beam is displaceable by a temperature-responsive bellows assembly (43). The valve component engages a valve seat (50) on an axially adjustable sleeve (51). A plate (54) can be removed and a tool inserted to turn the sleeve. Alternatively the sleeve may be toothed and engage a toothed pin rotatable in the body (not shown). <IMAGE>
Patent GB-2097130-A (GB)
Title: Moisture measurement
IPC: G01N33/00
Filed: 1982-04-02
Abstract: In the control of an industrial drying operation by reference to the moisture content of exhaust gas, automatic maintenance of a reliable control signal is provided in spite of derating through contamination of the moisture sensor (hygrometer) by systematically recalibrating the moisture sensor at intervals of time. A predetermined relationship between the moisture sensor output signal and the control signal is stored in a microprocessor, and this relationship is periodically varied in accordance with the condition of the moisture sensor in response to subjecting the moisture sensor to air sources of different known values of moisture content. A moisture content output signal may also be provided which is uninfluenced by the condition of the sensor. If, when using an air source having known moisture content, the moisture output signal varies by more than a predetermined amount in a given period, a warning signal is provided to indicate that the sensor is unsuitable for further use.

Title: Apparatus for adjusting the shape of moulded concrete articles
Inventor: PERSSON BENGT
IPC: B28B11/00
Filed: 1982-12-24
Abstract: After a concrete article, e.g. a curbstone, has been removed from its mould on a support pad 26, but before it hardens, it is fed on the pad 26 by a carriage 32 along infeed supports 28 to tables 8 where it is pressed against one or more straight edge rules 9, 10 which straighten the edge or edges of the article which they abut. The end surfaces of the article are also pressed by respective pressing plates 15 to adjust the length of the article. A profile member 12 moves lengthwise and rubs the article at a side remote from the rules 9, 10 thereby adjusting the cross-section of the article. The article is subsequently released from the rules 9, 10, the pressing plates 15 and the profile member 12 by the lowering of the tables 8 to the level of outfeed supports 30. <IMAGE>

Title: A method of manufacturing rigid frame building elements filled with hard foam plastics
Inventor: MIETTINEN JORMA KALEVI
IPC: B29C44/30
Filed: 1983-05-13
Abstract: The method comprises the use of prefabricated, rigid, dimensionally stable, hollow skeleton frames, the hollow interior spaces of which are filled with closed cell hard foam plastic serving as heat insulation, and the elements are subjected in a press to a compression pressure which overrules the foaming pressure exerted on the frame of an element from inside. The press comprises a lower frame equipped with lower roller conveyor means (4) and an upper frame with upper roller conveyor means (5), said conveyor means confining between themselves a conveying gap, into which the elements are fed and subjected to compression by means of bellows (7) on which the upper rollers (5a) are mounted. Conveying speed is adjusted such that expansion of the foam and the pressure generated thereby has substantially ceased by the time an element leaves the conveying gap.   <IMAGE>
