Title: Improvements relating to the measurement of fluid density
IPC: G01N9/00
Filed: 1978-11-08
Abstract: A vibrating fluid density transducer 10 provides a gas density measurement D, used in conjunction with a volume flowmeter signal frequency fB, to meter the mass of gas fed through a pipeline. D is subject to errors dependent upon the velocity of sound C in the gas. The errors are corrected to yield the actual density Da by application of a correcting formula (block 18) in which C is introduced by calculation (block 17) from a measurement of gas pressure P by a transducer P. The value of C may alternatively be measured directly, computed from a measurement of specific gravity or in the case of a liquid, be inferred from D or be preset. <IMAGE>

Patent GB-2054153-A (GB)
Title: Gas Monitors
IPC: G01N33/00
Filed: 1979-07-17
Abstract: A gas monitor which activates an alarm when a particular gas concentration is detected has means to inhibit alarm actuation when the detected concentration does not result solely from a concentration change. As described a low oxygen content (17%) alarm is prevented from actuation during sudden drops in ambient pressure. The inhibition operates with a sudden pressure drop curve B but not with a steady oxygen content drop curve A. Inhibition is produced when the rate of change of oxygen concentration exceeds a predetermined value e.g. the time for the oxygen content to decrease from 19% to 18% is less than a predetermined value. <IMAGE>

Title: Photosensitive materials
IPC: G03F7/34
Filed: 1979-08-23
Abstract: Photosensitive materials are described which may be used in a variety of applications such as making dry transfer materials, resist masks, printing plates and silk screen stencils. The material consists of two carrier sheets may be peeled apart and which are laminated together via at least two interlayers viz. a photosensitive layer and an image forming layer. Prior to exposure, if the carrier sheets are peeled apart the carrier sheet adjacent the photosensitive layer separates wholly from it leaving both photosensitive layer and image forming layer on the other carrier sheet. After exposure, if the sheets are peeled apart the whole of the photosensitive layer and at least part of the image forming layer remains attached to the carrier sheet adjacent the photosensitive layer. By incorporating adhesive in or adjacent the shearable image forming layer, the photosensitive material may constitute a material from which dry transfers may be manufactured simply by imagewise exposure and peeling apart.

Patent GB-2047905-A (GB)
Title: Focus Indicating Device for a Camera
IPC: G02B7/36
Filed: 1980-02-04
Abstract: The indicating device operates in a first mode when the image is almost in focus and a second mode, visually or audibly distinguishable from the first mode, when the image is exactly in focus. As shown, a photoelectric conversion element 13 e.g. a self- scanning array produces a time-series output signal dependent upon the brightness condition of an image of an object it, and a contrast detector 14 converts this signal into a voltage representing the image contrast. This voltage becomes a maximum when the image is exactly in focus, the maximum value being held by a capacitor C1 and being divided by resistors R2 and R3. When the contrast-representing voltage is greater than the thus divided maximum voltage, corresponding to the image being close to its in-focus condition, a light-emitting diode D2 is energised so that its brightness depends upon the focus condition of the image. When the image is exactly in focus, the brightness reaches a maximum. In an alternative arrangement (Figure 7 not shown), a sound reproduction transducer (113) is driven at a frequency dependent upon the contrast-representing voltage so that an audible signal is produced whose pitch reaches a maximum when the image is exactly in focus. <IMAGE>
