Abstract: 1472294 Semi-conductor stress transducer WELWYN ELECTRIC Ltd 18 Dec 1974 [28 Jan 1974] 03760/74 Heading G1N [Also in Division H1] The diffused semi-conductor Piezo-resistive elements of a Wheatstone bridge for measuring mechanical stress are so formed that the bridge, when mounted under its intended operating conditions, has a temperature coefficient of resistance within Œ 1% of a value α and a temperature coefficient of strain sensitivity (defined in the Specification) within Œ 3% of a value # where α + # + α##T = 0, #T being the range of temperature over which the bridge is adapted to operate, whereby the electrical output of the bridge for a given mechanical stress changes by no more than Œ 0À03% per ‹C over the temperature range #T. All, or only two, of the four bridge resistors may be semi-conductor Piezo-resistors, formed either in individual semi-conductor chips or in a common chip 46 as shown. Conventional B or P diffusion into Si is used to form the Piezo-resistors, the preferred method being described. In the structure illustrated a gap is left between the ends of adjacent Piezo-resistors 37, 38 to permit an external resistor 44 to be inserted in series with the Piezo-resistor 37 to reduce the output voltage appearing across the bridge in the absence of applied stress. A further external resistor 45 across the Piezo-resistor 38 reduces the temperaturedependence of any residual zero-stress output voltage, and in an alternative arrangement for achieving the same end a variable resistor 19 Fig. 5 (not shown), is used with its wiper connected to an output terminal of the bridge and its ends connected across the bridge input terminals.

Title: New derivatives of phenylacetic acid and their preparation
Inventor: FOUCHE JEAN CLEMENT LOUIS
IPC: C07C323/62
Filed: 1966-01-27
Abstract: The invention comprises 2-benzyl-phenylacetic acid derivatives of the formula <FORM:1122202/C2/1> in which X is halogen, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkylthio or trifluoromethyl. They may be prepared by hydrolysing a nitrile of formula <FORM:1122202/C2/2> e.g. with aqueous caustic potash.  The nitrile used as starting material may be prepared by esterifying the acid BCOOH with methyl alcohol, reducing the methyl ester to give the alcohol BCH2OH, halogenating this (for example with thionyl chloride) to give BCH2Y, where Y is a halogen and treating the halide with an alkali metal cyanide to give the required cyanide.  In the above formula, BCOOH represents the acids <FORM:1122202/C2/3> The acids of formula BCOOH may be prepared by reacting under Friedel-Crafts conditions phthalic anhydride with a compound of formula <FORM:1122202/C2/4> to produce acids of formula <FORM:1122202/C2/5> which may be reduced to give the required acids, e.g. by catalytic hydrogenation or by treatment with zinc dust in an ammoniacal medium.  Examples are given of the preparation of (a) 2-(4-methoxybenzyl)-phenylacetic acid; (b) 2-(4-chlorobenzyl)-phenylacetic acid; (c) 2 - (4 - bromobenzyl) - phenylacetic acid; (d) 2 - (4 - methylthiobenzyl) - phenylacetic acid; (e) 2 - (4 - methylbenzyl) - phenylacetic acid and 2-(4-trifluoromethyl-benzyl)-phenylacetic acid.

Abstract: 996,903. Automatic titration apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 30, 1962 [Feb. 2, 1961], No. 3928/61. Heading G1N. [Also in Division G4] Titration apparatus comprises a constant current regulator 12 for supplying current to an electrolytic cell 11, a working electrode potential sensing device 18, and means 17 for decreasing stepwise the regulated current level in response to a predetermined value of the potential sensed by the device. Preferably the rate of operation of a timing device is simultaneously decreased. Regulator 12 is variable by an error signal output from a comparison amplifier 13 the inputs to which are the potential drop across resistor 14, which p.d. depends on the call current, and a reference voltage from a standard cell (not shown). Oscillator 15 supplies timing pulses to a register 16. The potential sensing device 18 is connected to a standard calomel electrode 19 and controls a switch 17, which in turn controls the oscillator frequency and the reference voltage. When a predetermined potential (the maximum potential at which the most readily electrolysed constituent only is electrolysed) is reached the reference voltage and pulse frequency are halved, and this process is repeated each time the potential reaches the predetermined value (up to, say, ten reductions). The total number of pulses counted is a measure of the quantity of selected constituent. In a modification the reference voltage is maintained constant and resistor 14 is doubled at each step.
