Apparatus for determining the physical properties of filaments such as threads yarns tapes &c. particularly tenacity and elongation, under wet conditions in which the filament 1 is clamped between two clamps 2, 3, one of the clamps 3 being moved to tension and elongate the filament whilst the other clamp 2 is connected through an arm 4 to a device which measures the force exerted on the filament during elongation and the force necessary to break the filament, during each test the filament, clamps and support being submerged in a liquid 11 such as water comprises a body 9 dependable below the liquid level and means for altering the volume of the part of the body which is submerged so as to compensate for the variation in the submerged volume of the movable clamp 3 and for its support 5 as it is moved to elongate the filament. The body 9 is of uniform cross-section, the same as that of the support 5 of clamp 3. In the embodiment described the movable clamp 3 is always submerged and hence the movement of the body 9 into or out of the liquid by the same amount that the support 5 moves out of or into the liquid leaves the liquid level constant. The body 9 is joined to the support 5 by a bracket 6 and line 7.

Abstract: 1497067 Microwave heating apparatus C E M TIBBS 12 Feb 1976 [13 Nov 1974] 49145/74 Heading H2H Microwave heating apparatus comprises means whereby the output of the microwave generator is reduced whenever the heating cavity is lightly loaded. A microwave cooking apparatus comprises a heating cavity 1 which is energized by means of a magnetron generator either directly or by way of a waveguide energy launch device. The cavity is provided with an aperture 3 through which projects the base of a small incandescent lamp 5 which becomes incandescent by pick-up from the microwave energy in the cavity, the degree of incandescence being determined by the loading in the cavity, a cadmium-sulphide photocell 7 being associated with the lamp 5. The apparatus is energized from an A.C. supply 10, 11 over the contact 12 of a relay 22 when a contactor 13 is closed whereby a magnetron power pack 17 is energized across terminals 15, 11, the contactor 13 being held closed by means of a relay 16 and contact 14. With normal loading of the cavity 1, the brilliance of the lamp 5 is in the dull red wavelength region, the photocell 7 then having a resistance such that the current flowing through the relay 22 is insufficient to cause operation thereof. With a lightly loaded cavity the brilliance of the lamp increases into the blue or ultra violet region causing the resistance of the photocell to decrease. The current flowing through the relay 22 then becomes sufficient to cause operation of the relay to move its contact to contact 24 thereby de-energizing the magnetron power pack 17 and energizing relays 26, 27 which perform auxiliary functions relating to the heating apparatus. The lamp 5 may be provided with an energy pick-up probe 8.
