Title: Improvements in or relating to force transducers using piezoresistive elements
IPC: G01L9/00
Filed: 1968-10-21
Abstract: 1,249,878. Pressure transducers. CONRAC CORP. 21 Oct., 1968 [27 Oct., 1967], No. 49891/68. Heading H1K. A transducer comprises a number of silicon piezoresistive strain elements of the same conductivity type at the surface of a diaphragm and produced from a monocrystalline layer so oriented with respect to the crystal axes that it contains at least two directions of maximum and equal longitudinal piezoresistive response. The strain gauges are aligned with these directions. In the Fig. 1 arrangement strain gauges of P- type silicon of meander form with the meanders series or parallel connected are disposed in the positions shown on 111 and 100 axes of maximum piezoelectric response on opposite sides of the circle 28 of zero strain of a peripherally clamped diaphragm. Temperature compensating gauges 47, 48 are disposed on the zero strain circle with their lines parallel to the 100 axis of minimum piezoresistive response. The outer gauges are disposed on a circle of maximum strain while the inner ones are offset from such a circle to allow closer packing. The gauges may be formed by masked diffusion of acceptor impurity into an N-type silicon diaphragm, by overall diffusion followed by form etching, or by epitaxial deposition, or are formed from a monocrystalline layer isolated from the diaphragm by an insulating layer. More gauges than are necessary for the standard bridge connection are formed so that only the best matched ones need be utilised. In alternative transducers using P-type gauges the gauges are aligned with 111, 110 and 012 axes in a 112 crystallographic plane with 110 axes in a 111 plane or with 110 axes in a 110 plane. If the gauges are of N-type they are preferably aligned with 100 axes in a 100 plane.

Abstract: 1,201,288. Construction of break-spinning chambers. SCHUBERT & SALZER MACHINENFABRIK A.G. 23 Oct., 1968 [28 Oct., 1967], No. 50237/68. Heading D1D. A break spinning chamber 2 increases in its area of cross-section from the fibre supply pipe 51 towards the collecting channel 22, the wall extending between the pipe 51 and the channel 22 being constructed so as to have a sliding (=centrifugal force) value ( ) 3 which decreases ( frictional force ) towards the collecting channel. The sliding ( 1 ) value #G = (------) where Á is the co-efficient ( Á cos α ) of friction and α is the angle of inclination to the vertical of the wall) is decreased by altering the coefficient of friction and/or the angle of inclination. Accordingly the spinning chamber may be of constant inclination and have a surface of altering coefficient of friction (e.g. in Fig. 1, section 28 of wall has a higher coefficient of friction than Section 27, which is higher than section 26). Alternatively the chamber wall may be curved outwardly or may be composed of conical surfaces of different inclinations.

Abstract: 1363904 Elastic ply yarns INTER TEXTILES EUROPEEN 28 Oct 1971 [29 Oct 1970] 50275/71 Headings D1F and D1W A process for producing voluminous balanced elastic ply yarns from threads of discontinuous man-made fibres or a mixture of non- keratinous natural fibres e.g. linen, cotton, hemp or jute, and discontinuous man-made fibres comprises the steps: a) individually twisting at least two of the above threads in a first direction until each thread has a twist factor α, of 95-110; b) thermally setting the twist in the threads; c) twisting the thermoset threads thus obtained in the opposite direction to form a ply yarn having an initial twist factor α 2  of 110-125; d) thermally setting the initial twist of the ply yarn; e) untwisting the ply yarn by twisting in the first direction and overtwisting the ply yarn in said direction until it has a twist factor α 3  of 275-290 and heat treating it in this temporarily overtwisted state; f) returning it to its initial twist, and g) sizing it in a relaxed state before winding it onto a support. The twist factor α is defined by the relationship T=α#Nm where T is the number of turns per metre, and Nm is the metric count of the yarn. α 1  is preferably between 100 and 105, α 2  between 115 and 120 and α 3  between 280 and 285. The overtwisting of the ply yarn is preferably accompanied by an elongation between 0.1 and 2%. The thermosetting is carried out at a temperature in the neighbourhood of the softening point of the man-made fibre. The overtwisting of the ply yarn and the return to its initial twist is carried out using a false-twist spindle and is preferably under conditions which satisfy the following formula: take in formula: in which V<SP>b</SP> is the speed of the false twist spindle in rpm, α 3 #Nm is the temporary twist in turns per metre, T is the initial twist of the ply yarn in turns per metre, and C is the length in centimetres of the heating element transversed by the twist. The ply yarn is preferably returned to its initial twist with a shrinkage between 16 and 35%. The thermosetting of the twist in the single threads and the initial twist in the ply yarn is carried out at a pressure lower than 70cm of mercury and at a temperature of 80-100‹C for 15-30 minutes.

Abstract: 1415422 Automatic equalizers WESTERN ELECTRIC CO Inc 30 Oct 1973 [2 Nov 1972] 50514/73 Heading H4R [Also in Division G3] The flux density in a magnetic circuit is regulated by comparison with a reference value to form an error signal which is integrated and used to produce a magnetic field in the circuit. Integration proceeds only when the magnetic field is not being applied. As shown, the flux in an air gap 379 of a magnetic core 378 is used to control the resistance value of a magnetoresistor MR placed in the gap. This value determines the gain of an operational amplifier 31 in an automatic equalizer connected between a transmission cable 20 and a utilization circuit. In use, pilot tones at each of four frequencies are applied to the cable, and the amplifier output signal is rectified and filtered 370, and then compared with a reference signal in a subtractor circuit 371. The resultant error signal may be passed by way of an integrator 373 and amplifier 374 to core windings 377. Switches 372 and 375 are operated in anticoincidence so that the error signal is integrated only when no field is being applied by the wind - ings 377. In this way, it is arranged that the  remanent value of the magnetic flux density is regulated. Four gain-adjusting networks 34-37 are provided, each having a respective tone detector 380 which closes a corresponding switch 376 when the appropriate pilot tone is supplied to the cable 20.
