Title: Epoxy resin-butadiene polymer compositions
IPC: C08L19/00
Filed: 1979-12-17
Abstract: Compositions comprise an epoxy resin and two tipped butadiene polymers. Preferably a dihydroxy compound, such as a diphenol, is also included. The compositions are gellable to an incompletely cross-linked, but tack-free state which enables the compositions to be used as adhesives. Substrates are coated with the compositions, gelled and substrates assembled. The cross- linking is completed to laminate the assembly. The adhesive compositions of the invention can be formulated to be substantially solvent-free and therefore there is not the problem, associated with many currently used adhesive compositions, of removing hazardous solvents in order to obtain adhesion.

Patent GB-2080957-A (GB)
Title: Method of suppressing spurious voltages and of measuring fault resistance
IPC: G01R31/08
Filed: 1981-04-13
Abstract: A method of suppressing spurious voltages and a method of indicating the fault resistance RF when carrying out measurements with d.c. Murray bridge circuits on cables a,b with a stabilized measuring voltage source involves stabilizing the measuring voltage source Um with a low internal resistance for d.c. voltage but with a high internal impedance for a.c. voltages e.g. by providing a transistor T and an operational amplifier V connected as shown. A voltage which depends on the measuring current and therefore on the fault resistance is measured by meter I to give the value of the fault resistance. The method can be used particularly with telecommunications cables, and substantially reduces the effects of spurious voltages which can give rise to differential voltages between the cores. <IMAGE>

Patent GB-2086136-A (GB)
Title: Improvements in and relating to earth leakage circuit breakers
IPC: H01H83/02
Filed: 1981-08-12
Abstract: An ELCB which may be embodied in a plug includes first and second contacts 11, 12 which are bridged by a metal plate 14 slidably mounted on a spindle 13. The ELCB is set by operating a pushbutton 16 to urge the plate 14 against the force of spring 15 such that the end 14b of the plate engages contact 12, where it is held by a cam latch 18 controlled by a solenoid 17. When the push button is released the spring 15 urges the end 14a of the plate against contact 11. When an earth leakage current is detected, the cam latch 18 is withdrawn and the plate 14 pivots to disengage from the contacts 11, 12. The ELCB is trip free in that upon depression of the pushbutton 16, it is not possible to bridge contacts 11, 12 with the member 14 whilst the cam 18 is withdrawn. The plug arrangement is further rendered trip free by arranging the pushbutton 16 in a recess 25 in a surface which mates with a socket, so that the pushbutton can only be operated when the plug is removed from the socket. <IMAGE>

Abstract: The apparatus includes a plurality of extrudes (10, 110) which feed parallel ribbons (20, 120) of raw material along refractory rollers (35, 135) through successive chambers (30, 32) in a kiln and through an annealing lehr (80) to a cutting zone. The surfaces of the raw material (20, 120) are coated on three sides with a parting agent and on the side to be exposed, with a glaze or left uncoated. The firing chamber (32) of the kiln has opposed rows of burners (40) directed toward opposing ports (42). The rollers (35, 135, 36, 136) protrude through side walls and are supported on circumferentially spaced wheels (70a, 70b, 70c). Wheels (73a, 73b) synchronize the rollers. Manifold (56) connects the firing chamber (32) with the preheating chamber (30). The process uses a mixture of a small amount of soluble carbonaceous material and water with either a clay or silica charge to adjust the composition. Clay may be extruded as ribbons coated with parting agent and glaze, then fired, preheated, sintered above 20000 DEG F, and annealed. Cellulated vitreous clay products are then cut. A silica charge with a silica sand surface may be pressed with a material to form plates, and them fired in the kiln to form a cellulated, vitreous product. Consumable, sectional trays are also disclosed.

Title: Correction of astigmatism in electron beam instruments
Inventor: SMITH KENNETH CHARLES ARTHUR
IPC: H01J37/153
Filed: 1983-06-15
Abstract: An electron beam instrument having an objective lens coil 14 and stigmator coils 18 has its astigmatism corrected for by measurement of the contrast in the final image. The currents through the objective lens and the stigmator coils are adjusted in sequence iteratively to optimise the contrast. The optimum contrast may be either a maximum contrast or a minimum contrast depending on the nature of the instrument and its mode of operation. Measurement of contrast may be made by measuring the magnitudes of successive points of an image and calculating the variance. Alternatively two measurements of magnitude at each point of an image may be made and the covariance calculated. <IMAGE>
