Title: An improved joint for surgical and dental forceps and other instruments
IPC: A61B17/30
Filed: 1933-08-21
Abstract: 424,344. Pliers. KEETON, W., 103, Culford Road, De Beauvoir Town, London. Aug. 21, 1933, No. 23251. [Class 61 (ii)] [See also Group XXV] In pin -jointed surgical or dental forceps or other scissor-like instruments, designed so that the two members can be readily separated when required by sliding one member axially off the pin which is fixed to the other, both parts of the instrument are undercut concentrically with the pivot axis on the inner faces of their recessed abutting parts and have correspondingly shaped concentric portions on their outer faces to engage with the undercut portions so as to prevent axial separation of the parts in the normal position of use. Fig. 3 shows a pair of dental forceps formed of a pair of members 1, 1<a>, each comprising a handle and a jaw connected by a recessed part 3, the parts 3 on the two members abutting face to face and being connected by a pivot pin 2 fixed to one of the parts. The parts 5 of the jaws and handles, abutting on the parts 3, are undercut concentrically with the pivot axis, while the outer face of each part 3 is bevelled at 6 adjacent to the jaw or handle to fit in the adjacent undercut part 5 of the other member. In the position shown, the members 1, 1<a> may be separated by sliding off the pin 2, the parts 3 being cut away at the sides to pass between the parts 5, but in the normal position of use the parts 4, 6 are interengaged to prevent such separation. Fig. 6 shows the pivoted portion of one member of a pair of spring forceps, the other member being identical. A pivot pin 7 is fixed in one part and engages a hole in the other, and concentric with this each part has an undercut projection 4 on the side facing the other member and a bevelled part 6 on its outer face, the parts 4, 6 on the respective members interengaging to prevent separation of the members in the position of use. To prevent accidental rotation of the members to a position in which the parts 4, 6 are disengaged and the members can therefore be separated, each member is provided with a pin 8 and recess 9 for engagement with the corresponding recess and pin on the other. The invention is also applicable to parts connected by a removable pin or screw. The application to mouth gags is referred to.

Title: Improved apparatus for conducting a liquid and a gas which is soluble in the said liquid through a closed cycle of thermal operations
IPC: F01K25/06
Filed: 1919-09-24
Abstract: 139,732. Beadle, C. H. Sept. 24, 1919. Vapour engines.-Relates to the method of and apparatus for, obtaining energy for power-producing or refrigerating purposes from a source of natural or waste heat by means of a gas which is dissolved in a liquid and conveyed through a thermal cycle in which the gas is evolved at one point to be used for the production of power &c., and at another point is re-absorbed, while the natural or waste heat is added at a third point, the effusion of the gas being caused solely by the heat generated by its re-absorption, as described in Specification 20267/14. The invention consists in effecting the effusion of the gas and the saturation of the liquid in a single vessel, preferably arranged vertically. In the diagrammatic arrangement shown, gas from the saturated solution is effused at the lower end of the vertically-disposed annular vessel a, and passes up through the cooler and less saturated liquid above to the receiver b, and thence to the engine by a pipe c. From the engine, the expanded and cooled gas passes to a coil e, in which it is heated and increased in presure by a coil f heated by natural or waste heat. From this re-heater, a pipe g conveys the gas to the lower part of the annular vessel h, into which it passes through perforations p and mingles with impoverished liquid. As stated, the heat generated by the re-absorption of the gas in the lower part of the annular vessel h causes effusion of gas in the lower part of the annular vessel a. From the vessel h, the solution passes through a pipe q to a reservoir r and a pump s, bv which it is returned to the vessel a. Coils u, u<1> are provided for the initial adjustment of temperatures, and a reservoir v for gas can be heated or cooled by a coil v'. When the liquid level rises in the vessel b above the pipe i<1>, impoverished liquid flows from the vessel i into the receiver k, in which is a float valve m, which, when empty, rises and closes the end of the downcast pipe l connected to the lower end of the absorption vessel h.
