Title: Improvements in electric cables
IPC: H01B9/06
Filed: 1931-10-27
Abstract: 385,695. Cables. BEAVER, C. J., Bell Place, Stamford Road, FAIRFIELD, T. J., Newlands, Talbot Road, both in Bowdon, Cheshire, and GLOVER & CO., Ltd., W. T., Trafford Park, Manchester. Oct. 27, 1931, No. 29745. [Class 36.] To prevent permanent distortion of the lead sheath of a multicore impregnated cable by expansion of the impregnating compound, the sheath is shaped to conform as far as practicable to the external contour of the laid-up cores. As shown in Fig. 1, a three-coil cable having each of the insulated cores 2 wrapped with copper tape 3 is enclosed within a lead sheath 4 of trefoil section which contacts as far as possible with the tape wrappings 3. A protective covering of triangular section and consisting of an armouring layer 6 disposed between layers 5, 7 of jute or hessian is applied over the sheath 4. The sheath 4 is urged into contact with the cable cores by compressible resilient metal paddings 8 which may consist of metal strips having the V-shaped section shown or may be formed by wire helices having circular or triangular cross sections. In a modified construction, Fig. 4, a circular lead sheath 11, reinforced by a metal-tape wrapping 12, is applied over the trefoil-shaped sheath 4 and is protected by layers 5, 6, 7 similar to those shown in Fig. 1. Gas under pressure is applied to the spaces 13 between the sheaths 4, 11, a particularly high pressure being applied momentarily during the manufacture or installation of the cable to ensure good contact of the sheath 4 with the cores 2 and to expand the sheath 11. In applying the sheath 4, the unstranded cores are fed side by side to suitably shaped stationary dies of a lead press, the sheathed cable being drawn off upon a drum which is rotated about the axis of the dies.

Patent GB-762824-A (GB)
Title: Automatic temperature compensating apparatus and method therefor
IPC: G01N11/00
Filed: 1954-10-18
Abstract: 762,824. Electric viscosimeters. BENDIX AVIATION CORPORATION. Oct. 18, 1954 [Nov. 9, 1953], No. 29923/54. Class 40 (1). [Also in Group XXXIX] An apparatus for temperature compensating the electrical output of a viscosimeter comprises means fed with the output and including a temperature-sensitive device exposed to the fluid the viscosity of which is being measured and arranged to give a second electrical output which is proportional to the product of the first output and the deviation of the output of the device at the fluid temperature from its output at a reference temperature, together with means for combining the first and second outputs to give an output representing the viscosity at the reference temperature. The output of a viscosity probe of known type disposed in the fluid flow is fed to a computer which gives an output voltage proportional to ##. This is applied to an amplifier 23 part of the output of which is applied through constant impedance attenuator 24 to diagonal 26-27 of resistance bridge 25, the other diagonal 28, 29 of which is connected in series with the viscosity computer output voltage across an output meter. The bridge comprises resistance thermometer 15, variable resistor 32 and equal fixed resistors 33, 34. In operation the fluid is brought to the reference temperature and the bridge balanced by adjustment of 32 until the readings of meter 32 and the output meter correspond. It is shown in the description that voltage applied to the latter is represented by the equation e<SP>2</SP> where k=-, e being the output of the viscosity # computer. T and To are the actual and reference temperatures respectively and m is a design factor which can be varied by adjustment of attenuator 24. The equation representing to a first order of approximation viscosity variations with temperature is of the form where n is a constant characteristic of the fluid so that if the fluid temperature is altered and the attenuator then adjusted to give an output meter reading corresponding to the reading of meter 22 at the reference temperature the voltage e 0  will be independent of temperature over a range in which the approximations made in deducing the formulae are valid. A bridge with balanced resistance thermometers in opposite arms and coupled variable resistors in the other arms may be used to improve the sensitivity. Amplifier 23 may be a magnetic amplifier (Fig. 3, not shown), (see Group XXXIX). Specification 736,204 is referred to.

Abstract: 210,836. Wise, W. L. Nov. 8, 1922. Switches, actuating.-Limit switches and other devices adapted to function when a machine &c. has completed a predetermined movement or number of revolutions are operated in response to the arrival of three or more elements in a gear train, having different speeds of rotation, at a given relative position. In the form shown in Fig. 1, three differing gear wheels 1, 2, 3 meshed in series carry insulated conductors which in a given relative position are adapted to co-engage and complete a relay circuit connected to terminals 6, 7. The speed ratios of the wheels are such that they arrive in the position shown only after they have each performed a given-number of revolutions corresponding with a given movement of the machine &c. controlled. In the modified form shown in Figs. 2 and 3, which might be applied to a clock mechanism, the memberscarried by the wheels co-engage as the wheels reach a. given position, the last element of the series mechanically operating a limit switch or other controlling device. As this position is approached (Fig. 3) the member 14 on wheel 1 engages the sliding element 16 on the wheel 2 which moves the spring-controlled member 17 on the wheel 3 so that its end 17<b> engages the forked end 19 of a pivoted lever 20, further movement of the wheels moving over the lever 20 and so operating a switch blade 21 or other device. This arrangement may be employed in conjunction, with a clock to release a clock-work alarm.
