Filed: 1974-06-10
Abstract: 1464096 Abrading E G FELDCAMP 10 June 1974 [12 June 1973] 27824/73 Heading B3D A method of finishing an aperture in a component, such as an extrusion die, drilled passage in a valve block, or window of an anti-friction bearing cage, comprises placing a billet of an abrasive compound in a chamber of a press 12, forcing the abrasive compound through the aperture, and receiving the abrasive compound in a confined space 18 whereby to reform it into a billet for subsequent re-use. The press has a ram 12 movable along vertical guides 13 above a platen 10 having a stepped bore in which is a replaceable plate 15 having a bore 11 aligned with a bore in a replaceable wax recovery gallery 14. The box 11 in the plate 15 is flared and, in operation, encompasses the workpiece aperture and contains a body of the abrasive compound through which back pressure is applied to the abrasive in the workpiece aperture. A recovery cylinder 17 is pivotally mounted on a projection 23 on a plate 16 secured beneath the platen 10. A hydraulic rotary actuator 26 is operable to pivot the container between an operative position, as shown, in which the container is releasably secured by a hydraulically actuated latch 20 engaging a lug 19, to a horizontal position wherein a billet of the used abrasive compound can be ejected from the container for re-use. The container 17 has a hydraulically operated piston 22 connected to a ram 25 supplied with hydraulic fluid at a pressure proportional to that applied to the press 12 so that as the abrasive compound is forced through the workpiece aperture, a back pressure is applied in the container 17. The container is slightly smaller than the chamber of the press so that a billet formed in the container is easily received in the chamber of the press. Billets of successively finer abrasive may be used ranging from a grit size of 150 to 1000, the abrasive being silicon carbide grit mixed with plasticized petroleum wax. The finished aperture may be cleaned by using a billet of clear wax and washing. In another embodiment, the recovery cylinder is horizontal and has a side entry for receiving used wax and an end plate which is removable for ejecting the billet.

Title: Improvements in apparatus for determining the percentage change in weight of a sample following treatment
IPC: G01G23/365
Filed: 1960-08-11
Abstract: 895,498. Measuring electrically. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Aug. 11, 1960 [Aug. 19, 1959], No. 27862/60. Class 40 (1). The percentage change in weight of a sample following treatment is determined by obtaining a voltage which is proportional to the combined weight of the sample and a container, automatically subtracting from it a voltage which is similarly proportional to the weight of the container, adjusting the resultant output so that an indicator gives a null reading, and then treating the sample, the indicator indicating the percentage change in weight directly. The apparatus may be used to determine the regain of wool, or the grease and dirt content of a sample of fibre. In one embodiment (Fig. 1) a load cell T is connected in series with a voltage source - V c  giving a voltage equal and opposite to that produced by the empty container on the load cell. The load cell and source are connected across a potential divider P the tap of which is connected to a constant voltage source V s  through a high impedance current meter M. With a sample in the container the tap on divider P is adjusted until meter M reads zero. The sample is then treated and the meter reading is proportional to the percentage change in weight. In a modification (Fig. 2) a variable resistor R and a fixed resistor Q are connected in series across source V s . With switch S in position (a) the meter is adjusted to zero as before but after treatment the switch is moved to position (b) and the meter re-adjusted to zero using variable resistor R, the value of which is then proportional to the percentage change in weight. In a third embodiment the load cell and source are connected in series with a voltmeter of adjustable sensitivity, comprising a meter and a series and a parallel resistor. With a sample in the container the sensitivity of the voltmeter is adjusted to give a particular reading, defined as zero. After treatment of the sample the new meter reading is proportional to the required percentage.

A device for repairing yarn breakages in spininimg or twisting frames comprises two members 4, 5, see also Figs. 3a, 3b not shown, defining a tapered 'or wedge-shaped slot which catches the broken end running, to the spindle should the yarn break on leaving delivery rollers 3 and a piecing mechanism comprising plates 13, 14 rotatable about a shaft and carrying a roller 12. The device is traversible to remain in line with the swing being traversed across the drafting rollers. Normally plates 13, 14 carrying roller 12 and the end catcher 4, 5' are pivoted away from rollers 3, see Fig. 4a not shown. When a yarn breaks the end is caught between plates 4, 5 and tends to rotate the plates about a shaft 7 on which they are mounted. Thus an extension 9 of the plates actuates a sensor 11 which results in air being fed to a piston-cyclinder device 25, 26. Movement of piston 25 pivots plate 13 until roller 12 contacts and is rotated by lever delivery roller 3. By means of a spring 15 plate 14 is also rotated until an extension 17 thereon comes into contact with lever roller 3. During these movements roller 12 sweeps across the held broken end and carries the yarn with it, see Fig. 4b not shown. Rotation of roller 12 against roller 3 pulls the broken end from the plates 4, 5 and engages it with the sliver still issuing from rollers 3. As soon as the end leaves plates 4, 5 sensor 10 is released, the air supply to piston 26 is cut off and a spring 28 pushes plates 13, 14 back to their normal inoperative position. Normal spinning or twisting is then resumed.
