Title: Controlling mechanical test apparatus electrically
IPC: G01N3/36
Filed: 1980-12-31
Abstract: A notched specimen 10 is subjected to a cyclically varying load applied by a hydraulic actuator 24. Strain gauges in a load cell 21 feed an applied load signal to amplifier 33, and strain gauge 16 on the back face of the specimen feeds a strain signal to amplifier 33 which adds the signals in a weighted ratio and produces an output representing  DELTA K, the alternating stress intensity factor at the tip of the crack. The output of amplifier 33 is compared in servo amplifier 36 with a reference value of  DELTA K from 37, and a resultant signal controls servo valve 25 of actuator 24 to reduce the load applied to the specimen as the crack grows, to maintain  DELTA K, and hence crack growth rate, constant or to vary crack growth rate in a chosen manner. <IMAGE>

Title: A method and apparatus for reducing the risk of spontaneous combustion in a gas mixture
IPC: A62C3/00
Filed: 1981-01-10
Abstract: The invention relates to a method and apparatus for reducing the risk of spontaneous combustion in a gas mixture containing at least oxygen and particulate matter in suspension. The method and apparatus overcomes the problem of having to increase the temperature of the gas mixture in order to reduce the level of oxygen when the oxygen level exceeds a certain critical level at which spontaneous combustion may occur. Essentially, the method includes the step of introducing an inert type gas, for example, carbon dioxide into the gas mixture when the oxygen level exceeds the critical level. The apparatus is illustrated connected to a Pico drier (1) having six spiral tube driers (2 to 6). The apparatus comprises jets (31) which introduce the carbon dioxide into the conveying gas stream through the driers (4 to 6). <IMAGE>

Patent GB-2089972-A (GB)
Title: Noise filter for combustion gas analyzer
IPC: G01N21/27
Filed: 1981-09-29
Abstract: A method and apparatus for removing noise from measurement signals from a sensor 12 used particularly in analyzing combustion gases, the apparatus including a rotating wheel 21 having a plurality of openings. As the wheel rotates, openings permit electromagnetic radiation from a source 11 to pass through the wheel 21 and through the combustion gas 7 to strike the sensor 12. The radiation 40 causes the sensor to generate an output signal indicative of the radiation and the background noise. At least one other time during the rotation of the wheel, a solid portion of the wheel prevents radiation emanating from the source from striking the sensor. At such time the sensor output signal will be solely a function of the noise in the system. By subtracting the sensor output signal corresponding to the obscured source from that corresponding to the exposed source, a more accurate analysis of the combustion gas(es) is achieved. <IMAGE>

Title: Reinforcing rock structure and nut elements therefor
Inventor: CLARK CARL A
IPC: F16B37/00
Filed: 1982-11-26
Abstract: A bar (16) is fixed and tensioned in a hole (12) drilled in a rock face (14) by means of a nut element (30) screwed onto the outer end of the bar. Initially the nut element is screwed onto the bar until the end of the bar engages an annular dome-shaped abutment portion (46) whereafter rotation of the nut rotates the bar which thus mixes two components (22, 24) of a resin grout from a cartridge (20) that has been ruptured at the inner end of the hole. When the grout has set to rigidify the bar, further torque applied to the nut element causes the end of the bar to displace the portion (46) so that the nut element screws further onto the bar and forces a plate (28), which has been threaded onto the bar, hard against the rock face (14). <IMAGE>
