Title: Improvements connected with water-flow calorimeters
IPC: G01N25/42
Filed: 1931-11-23
Abstract: 385,084. Calorimeters. NORTON, A. L., Metchley, Prospect Hill, Redditch, Worcestershire. Nov. 23, 1931, No. 32366. [Class 97 (iii).] Water from a water-flow gas calorimeter, falling below a certain level in the limbs of a U-tube, releases a gaseous charge adapted to impinge on a quantity of liquid which then closes the open end of a gas inlet pipe and cuts off the gas supply. In the form shown, the limb 1 of a metallic U-tube is open to the atmosphere, receives water from the calorimeter, and communicates by a pipe 6 with a level indicating tube 5 having at the bottom an escape orifice 7 the size of which in relation to the rate of flow determines the head of water in the U-tube. A dipping pipe 4 connected with the gas supply pipe 3 extends into the other closed limb 2 of the U-tube which communicates through a pipe 8 with a closed chamber 9. A gas outlet tube 10 projects into the chamber 9 below the surface of a quantity of water (or mercury) therein. Inside the tube 10 there is a gas inlet pipe 11 depending from the supply pipe 3 and terminating above the bottom of the tube 10. In use water is supplied to the U-tube and the level rises above the end of the dipping pipe 4. A vent tap 12 in the chamber 9 is momentarily opened, so that the pressure of gas in the pipe 3 depresses the liquid surface in the tube 10 allowing the gas to pass from the pipe 11 to the tube 10 and from thence to the calorimeter. If the water supply fails the level drops in the U-tube and the pipe 4 becomes unsealed and communicates with the chamber 9 causing the liquid therein to rise in the tube 10 and seal the pipe 11, thus cutting off the gas supply. According to the Provisional Specification the gas inlet pipe may be closed by a valve or diaphragm.

Abstract: 605,895. Knot-tying devices. FIELDING, J. T. Jan. 3, 1947, No. 32564/45.[Class 112] In a hand-carried device for tying a knot similar to a weaver's knot, of the kind comprising a rotating central tying and gripping bill and side guide plates, the guide-plates are slotted in such a manner that when the yarns are inserted one of them engages under the bill and the other is passed over the bill and across the first yarn. The frame of the_device, in the form shown, comprises a plate 2 fixed to a bracket 5 which is strapped to the fingers; this plate is formed with a hook 30. A stud 12 carries a rotatable disc 10 with lugs 13, 14 in which the spindle of the tying bill 26 rotates, under the action of an arcuate rack 17 on the plate 2 engaging notches in the spindle, when the disc is rotated on the stud 12 by means of a trigger 18 against the action of a return spring 23. The bill 26 comprises a pivoted member 28 between two fixed members, the pivoted member having a broad tail which engages an eccentric hole in a return extension 14a of the lug 14 to open and close the jaws of the 'bill by cam action. The mechanism is enclosed by a cup-shaped cover 3 slotted to fit on the lugs 13, 14, on which it is held by a spring wire 21, and carrying a guide-plate 48 for the yarns. A second guide-plate 44, on the other side of the disc 2, is carried by a sliding member 31 which is actuated, against a spring 36, by a tooth 32 on the disc 10 projecting through a slot in the disc 2 and is guided by this tooth and by a lug 34 on the disc 2 engaging a slot in the member 31. The yarns to be connected are first laid in notches 43, 47, respectively in the guide-plate 44 and are then passed together into a slot 49 in the guide-plate 48, this slot being so shaped that the yarn from the notch 47 engages under the tying bill (which is concealed by the tongue 42 of the guide-plate 44 in Fig. 1) while the other yarn is lifted past the end of the bill and brought down across the former yarn. On operation of the trigger 18, the member 31 and guide-plate 44 now rise to clamp the first-mentioned yarn against the hook 30, and the disc 10 and guide-plate 48 rotate, carrying the bill 26 with them and at the same time rotating it and actuating its movable member 28 so that the yarns are gripped, cut, and looped on the bill in the usual manner, the loop then being stripped off the bill (which has now made a complete revolution) to form the knot by the tension of the yarn held by the hook 30 and further rotation of the bill tightening the knot and causing the yarn ends to be pulled out of the jaws of the bill.
