Patent GB-2096601-A (GB)
Title: Process for producing methacrylic acid
IPC: C07C51/23
Filed: 1982-03-04
Abstract: Methacrylic acid is prepared by the catalytic gas phase oxidation of one or more of the gases isobutylene, t-butanol, methacrolein, isobutyraldehyde and isobutyric acid with molecular oxygen, quenching the reaction product from the oxidation and than recovering methacrylic acid from the quenched product. It is possible to achieve a high concentration of aqueous acetic acid in the solution formed as by-product by recycling the by-product aqueous acetic acid solution to one or both of the oxidation or quenching steps.

Title: Ventilating buildings
Inventor: ZAMBOLIN MARCO
IPC: F24F7/10
Filed: 1982-07-23
Abstract: In a building, particularly an industrial building, air is admitted, at outdoor temperature, into a zone below the roofing, in order to decrease the thermal gradient between the upper and the lower part of the building, and thus diminish the dissipation of heat through the roof. A false ceiling (1) made of porous, preferably translucent material permits uniform distribution of the air flow from the upper zone (2) to the lower area. The air is supplied at super-atmospheric pressure through a duct (3) and distributor (4). <IMAGE>

Patent GB-2350248-A (GB)
Title: Furnishing information to determine the position of a body
Inventor: MONTGOMERY WILLIAM JAMES
IPC: A23C9/158
Filed: 1983-06-23
Abstract: To determine two positional co-ordinates of a point (D) within a space, a beam (10) of radiation is caused to illuminate a part of the space and is deflected cylindrically over the space, the beam being modulated in phase with the cyclical movement such that the radiation incident upon the point (D) includes enough information to identify the point. Radical co-ordinates r,  r   are defined respectively by (i) shaping the beam so that duration of exposure of the point D to radiation is a measure of r and (ii) pulsing the beam so that pulse frequency varies with   r  . In a alternative embodiment cartesian co-ordinates are determined by scanning two beams across the space and pulsing them so that pulse frequency indicates displacement r the x and y redirection.
Patent GB-2179612-A (GB)
Title: Aircraft instrumentation
Inventor: BENNETT PETER JOHN
IPC: B64D43/00
Filed: 1983-07-11
Abstract: In an aircraft attitude indicator as presented in a head up display format an aircraft symbol (11) indicates pitch angle with respect to pitch bars, such as pitch bar (12). The pitch bars are labelled to indicate actual pitch angle (eg (14)). The aircraft symbol (11) is fixed in the display (10) and the pitch bars move across the display in response to changes in pitch. The bar spacing is varied with pitch angle, as may be seen by comparing the spacing between bar pairs (eg (12,30) and (31,32)). Thus the number of bars in the display gives a pilot an analogue of pitch such that attitude may be assessed without reading pitch bar labels. In particular the 'ladder effect', as occurs in prior art indicators when looping manoeuvres are performed and rapid movement of pitch bars occurs at rate at which pitch bar labels cannot be read, is avoided. <IMAGE>
