Title: Improvements in or relating to a boring tool, particularly for boring taper holes
IPC: B23B51/00
Filed: 1938-09-02
Abstract: 518,688. Drills. STEVENS, A. H., (Shawlock, Inc.)..Sept. 2, 1938, No. 25726. [Class 83 (iii)] In a tool for.drilling tapered holes the cutter is loosely supported within a bore in the shank having flat side walls for guiding the cutter and against which it pivots in one direction, an inclined stem on the cutter being engaged by a sleeve slidable in the shank and normally urged forwards by a spring. The tool comprises a hollow body 10 attached by a pin 14 to shank 42 and haying a square-section axial hole 12 to receive the stem 21 of the bit 15. The stem is loosely supported in the hole by a pin 22 and has two opposing flat sides which are a close fit against the sides of the hole and sides at right angles thereto which permit the stem to rock. The inclined portion of the stem passes through a block 38 slidable in a slot 39 in the body 10 and attached to a sleeve 24 surrounding the body. A spring 25 presses the sleeve against a thrust washer 27 and another sleeve 26 which carries a work-engaging member 28 provided with apertures 30 and spurs 31 to penetrate the work. An outer sleeve 32 pinned to the shank at 34 has a lower flange 35 co-operating with a felt washer 36 on the sleeve 26 to limit the downward motion of the latter and provide lubrication. In operation, the spring 25 maintains the sleeve 24 &c. in the lower position and the bit abuts either against the shank 42 or against the lower end of the body 10, and the tool is rotated and fed downwards to cut a parallel hole in the work. When the member 28 meets the surface of the work, further motion of the sleeve 24 and block 38 is prevented and,the stem 21 slides through the block to rock the bit and cause the base of the hole to be counterbored as shown, three sides of the stem always remaining in contact with the interior surfaces of the body to give it adequate support. In a modified form of bit a twisted body 112, Fig. 14 has a centre point 116, side points 118 and radial cutting-edges 115 which are swept forwardly and relieved on the end faces. One edge 118 of the bit is relieved to allow it to cut laterally whilst the other is cylindrical to guide the bit in forming the preliminary cylindricalhole. The upper end of the hole may be countersunk by means of a second cutter 148 and the bit is then arranged to project further from the body.

Abstract: 302,744. United Water Softeners, Ltd., and Lawrence, H. S. Sept. 29, 1927. Purifying Liquids.- Salt for regenerating base-exchange material in watersoftening apparatus is moistened, so as to convert it into a sludge or slurry, and drawn into the apparatus by means of an ejector. Crude water enters a treating vessel 1 through a pipe 2, valve 3, ejector 4 and pipe 5. The suction inlet of the ejector communicates by a pipe 6 fitted with a valve 7 with a point near the bottom of a small box 8. A fourway connection 11 is in communication with the lower part of the vessel 1, through a valve 16 with the outlet pipe 15 for softened water, through a valve 14 with a waste outlet pipe 13, and through a. valve 10 with the pipe 2. Normally water enters through the pipe 2 and passes away through the pipe 15. For regeneration, salt is placed in the box 8, and the valve 7 slightly opened. The system being under pressure water will flow through the pipe 6 and slurry will be formed in the box. The valve 16 is next closed and the valve 14 opened. The slurry will be drawn through the ejector and the base-exchange material regenerated. Washing will follow, the wash water also passing away through the pipe 13. When a back wash is desired the valve 3 is closed and the valve 10 opened, the wash water in this case passing away through a pipe 17.

Title: Improvements in or relating to apparatus for measuring the quantity of heat suppliedby a liquid flow
IPC: G01K17/14
Filed: 1953-09-22
Abstract: 733,752. Measuring quantity of heat. GAILLOUD, H. Sept. 22, 1953 [Sept. 22, 1952], No. 26163/53. Class 97 (3). Apparatus for measuring the quantity of heat supplied by a liquid flow at variable temperature, of the kind comprising a meter and a distributer operated by means responsive to the temperature of the liquid or to the difference in temperature at two points of a circuit, the distributer being adapted to direct into the meter, respectively through two closing devices controlling the flow of liquid, a part of the flow proportional to the temperature thereof, the remainder flowing through a by-pass, is characterized in that the aforesaid meter is of the type wherein the fall in pressure is proportional to the square of the speed of liquid flow therethrough, and in that the distributer is arranged in such a manner that the variable cross-sections of the closing devices (which cross-sections determine the distribution of liquid between the meter and the by-pass) are maintained so as to satisfy the following relationship automatically and independently of the speed of the liquid where A, B, C are the cross-sectional areas respectively of the closing device of the meter, the closing device of the by-pass, and a gauge of constant cross-section equivalent to the meter, #T is the temperature scale of the apparatus, #T=Tmax - Tmin, and T is the temperature of the liquid. The apparatus may be of a form responsive to a temperature difference at two points in a circuit; in this case T is the temperature difference. As shown in Figs. 1, 2, liquid enters a chamber 2 by way of a conduit 3 and passes through apertures 14, 15 in a plate 10 to cavities 4, 5. A conduit 6 leads from cavity 4 to a meter 7, and a by-pass 8 leads from cavity 5 to the outflow from the meter. Meter 7 is of the kind wherein the fall of pressure is proportional to the square of the liquid flow. A bimetallic strip 16 mounted in chamber 2 controls a plate 12 which slides across plate 10. As the temperature rises, aperture 15 is progressively covered and aperture 14 progressively uncovered, so that the liquid, at first flowing entirely through the by-pass, flows more and more, and finally entirely, through the meter. Aperture 15 is of constant width, but aperture 14 has its sides curved in such a manner that the formula stated above is satisfied. In modifications, the apertures are formed in a cylinder and covered or uncovered by a sleeve, or the apertures are both of constant width and plate 12 is moved through a lever with a cam slot therein. In a further modification, the bimetallic element is of spiral form and rotates a plate over apertures in a disc. A differential apparatus measuring the quantity of heat supplied to, e.g., a radiator, has two spiral bimetallic elements, one situated in the inflow and the other in the outflow. One element is wound on a fixed spindle but rotates the spindle on which the other is mounted, the latter element rotating a plate over apertures in a disc.
