Title: Improvements in or relating to instruments for testing the deflection and oscillation of bridges and other structures or the components thereof
IPC: G01M5/00
Filed: 1926-02-02
Abstract: 264,027. MacFadden, R. R. Feb. 2, 1926. L i n e a r dimension gauges.-One part of the recording means such as the stylus, is carried by a heavy body depending from the structure the deflections of which are to be measured, while the chart is attached to the structure, so that the inertia of the heavy body is utilized to maintain the stylus stationary whilst the chart moves to receive a record of the deflections. As shown in the Figure, the heavy body is divided into two parts, the lower one I being suspended from the upper one i and carrying the stylus k. The bodies are carried by a knife-edge e from a bracket a clamped to the beam to be tested, and the axis of suspension of the lower body I passes through the centre of gravity of the body i. Each body may be hollow and loaded with water, and light springs v restrain chance swinging movements caused by wind &c. The chart d may be carried on a drum mounted on a spindle having a pulley or pulleys D, and a wire l passes over one of the pulleys and is anchored to the ground, so that the drum d is rotated when the beam is deflected and the deflection is recorded on the chart. The records of the deflections and oscillations respectively may be enlarged by using the smaller pulleys D, and by adjusting a pin r passing through a slot p in the stylus carrier, the carrier being pivotally connected at q to the support j extending from the body I.

[Also in Division C3] A poly(aminoacid) is treated with a solution comprising a hydrogen halide in a mixture of water and alcohol at a concentration which effects a depolymerisation such that the reduction of the degree of polymerisation by 50% takes more than a minute and in a quantity sufficient to take all the partially depolymerised polyamide into solution, and the resulting solution is then neutralised with an alkali to form a precipitate. Preferably the solution is allowed to stand for about a day before neutralisation. A softening agent e.g. polyoxyethylene sulphonate or menthol or other phenol may be mixed with the solution or neutralising agent. Precipitation may be effected in the presence of a filler, e.g. rare earth oxides, or in situ on a fabric. In the case of nylon 6 HCl at a concentration exceeding 2 moles/litre may be used. The precipitation product is stated to have ionic sites which cause reticulation giving a cellular product having very different electrostatic properties from the starting polyamide. Uses. The application of the process with neutralisation effected in situ on a fabric is stated to improve opacity, moisture-absorbance and fire-resistance and to modify the dyeing properties. A further treatment with aqueous sodium bicarbonate forms bubbles in the coating and give a simulated leather appearance. Polymer precipitates on a filler may be used for radiation-deflecting or absorbing screens. Specified fabrics are cotton, polyester and nylon. In the case of nylon contact with the solution prior to neutralisation should be brief (less than 10 and 3 seconds for nylons 66 and 6 respectively) and the fabric may first be dipped in water.
