Abstract: 1,094,862. Semi-conductor strain gauges. ETHER ENGINEERING Ltd. March 29, 1965 [March 31, 1964], No. 13333/64. Heading H1K. [Also in Division G1] A transducer has a plurality of elongate piezo-resistive semi-conductor elements formed integrally with an edge-clamped circular diaphragm at one of its faces, and is so designed that substantially no adverse interaction occurs between the response of each element to transverse and longitudinal strain. This is achieved either by so orientating an element relative to the crystal structure that the response to transverse strain is much less than that to longitudinal strain (or vice versa) or by positioning the element on the diaphragm in a region where it will be strained in only one of the transverse and longitudinal directions. The diaphragm is made of a monocrystalline semi-conductor such as silicon and the elements are formed by localized diffusion or epitaxial growth. The embodiments illustrated (not shown) each have four active elements which in operation are used as the four arms of a bridge. The transducer is used to measure the differential pressure between the two sides of its diaphragm. Because of the clamping there will be little tangential strain at the periphery of the diaphragm and the diaphragm will have a double curvature under the impressed load resulting in the presence of a neutral circle at which the radial strain is zero. The position, orientation relative to the crystal axes, and conductivity type of the elements are chosen bearing in mind these facts. It is stated that the transducer may have only two elements (responding in opposite senses) which are connected in a half-bridge arrangement.

Abstract: 1395905 Telescopic position-adjusting fluid devices AUTOMOTIVE PRODUCTS Ltd 8 May 1972 [6 May 1971] 13437/71 Heading F2S In a telescopic position-adjusting device for an aircraft seat back (Fig. 1, not shown), in which liquid is normally prevented from flowing into or out of a chamber 17 from or into another chamber by a valve member 33, the liquid in the other chamber is acted on by gas separated from it by a deformable diaphragm 21. Contraction of the device, corresponding to movement of the seat back from an upright to a reclined position, is normally prevented since liquid can not leave the chamber 17 because of the closed valve member 33. Operation of a pin 37 either directly or by fluid pressure or a Bowden cable (not shown), causes a plunger 34 to push the valve member 33 off its seat 32. An external force on the seat back in the appropriate direction then contracts the device, liquid flowing out of the chamber 17 and via 30, 29, 35 to the other liquid chamber (formed between the diaphragm 21 and the chamber 17), against the pressure of the gas. Extension of the device, corresponding to movement of the seat back from an inclined position back into an upright position, can be effected in either of two ways. The pin 37 can be operated as above to push the valve member 33 off its seat. The pressure of the gas will then force liquid from the other chamber via 35, 39, 30 into the chamber 17 to extend the device. Alternatively, an external force applied to the seat back in the appropriate direction moves a member 20 into engagement with a peg 36 on the plunger 34 and so pushes the valve member 33 off its seat, the pressure of the gas then continuing the extension movement as above. Small changes in temperature causing changes in the volume of liquid in the device are compensated for by deformation of the diaphragm 21. In the event of a fire the fusible plug 23 melts and releases the gas from the device. The maximum stroke of the device is determined by the position of a projection 40 with respect to an opening 41. This position is adjustable (Fig. 2, not shown).
