Patent GB-2037658-A (GB)
Title: Stiff woven polyethylene fabric and process for the production thereof
IPC: B32B27/12
Filed: 1979-11-23
Abstract: A fabric 30 comprising an oriented polyethylene film 35 adhesively laminated to a woven structure 32 of oriented tapes 33, 34 through a layer 31 of synthetic plastic polymer such as polyethylene is produced by extruding the polymer layer 31 between the woven layer 32 and polyethylene film 35 to laminate the layers and has improved stiffness particularly useful when automatically closing the mouths of sacks made of this fabric after filling. When the polymer layer has a lace- structure with holes 36 produced by incorporating a blowing agent with the polymer on extrusion, the resultant fabric also has improved tear resistance. The ratio of the area of the holes 36 in the lace layer to the total area of the lace layer is preferably between 0.6 and 0.8. <IMAGE>

Title: Oil Separator
IPC: E03F5/16
Filed: 1980-01-28
Abstract: Oil and sludge are separated from contaminated water in a settling vessel divided into two concentric chambers (4, 5) through which the water flows in succession. In one embodiment, the inner chamber (4) is a sludge depository, and the outer chamber (5), which is annular in shape, collects the oil. A flow connection (17) allows water to overflow from chamber (4) into chamber (5) on one side of a radical wall (6), which constrains the water to flow round chamber (5) to underflow outlet (9, 21). An oil-level alarm (22) and manhole (10) are provided. <IMAGE>

Title: Kerving
IPC: B28D5/00
Filed: 1980-06-25
Abstract: In order to kerv a gem stone, a moving saw blade is fed with respect to the stone until the blade contacts the stone (b), feed is then ceased for a substantial period of time (b-c), so that a very small groove is cut in the surface of the stone, and then the blade is fed slowly to cut a kerf at the position of the groove (c-d).

Patent GB-2064081-A (GB)
Title: A Method of Heating Coke Ovens
IPC: C10B21/20
Filed: 1980-08-15
Abstract: This invention relates to a method of heating coke ovens with a rich gas mixed with varying proportions of relatively lean gas, with regenerative heat exchange between the combustion air and burnt gases only. In the method the pressure of the gas supplied to the burners is kept at a constant value selected to correspond to the maximum admixture of lean gas in the mixed gas and any reduction in the quantity of lean gas supplied is compensated for by cutting off heating for an interval within each regenerative half-period, in which the reduction of lean gas occurs. In this way the heat supplied during a regenerative half-period can be controlled to a predetermined value.

Filed: 1980-08-28
Abstract: Dihydropyridines of formula   <IMAGE> where R<6> is lower alkyl and R<5> is lower alkyl or aryl (lower)alkyl are prepared by a novel process from sodium or potassium salts of 1-substituted-1,6- dihydro-5-hydroxy-3[2H]-pyridones. The dihydropyridines are useful as intermediates for pharmacologically active 1-optionally substituted-3- phenyl or substituted phenyl- piperidin-5-ols and esters. Some of the piperidinols and esters are novel; those where the 1-substituent is aryl(lower)alkyl are intermediates, those where the 1-substituent is cycloalkyl(lower)alkyl are analgesics or antidepressants and those in which the 1-position is unsubstituted are anti-secretory agents.

Title: Audio location of a sound source
Inventor: SOILLEUX PETER JOHN
IPC: G01S3/802
Filed: 1981-05-15
Abstract: A pair of matched microphones (5) mounted either side of an acoustic obstacle (3) are used to give approximate location of a sound source by stereophonic effect. The microphones (5) are rotated as a pair towards the source and microphone output signals are compared during this rotation until they are of equal amplitude or, are co-incident in time, or both, according to sound frequency, to give more accurate location of the sound source. The microphones (5) may be mounted on the outside of a helmet. Alternatively, the microphones (5) may be mounted orthogonal to a sight (7), the line of sight intersecting the axis of rotation. Artificial pinnae of different size may be mounted around each microphone transducer, to provide front to rear spatial discrimination. <IMAGE>
