Title: A thread-feeding surgical needle
IPC: A61B17/04
Filed: 1946-10-04
Abstract: 630,693. Hand sewing-tools. MONNIER, J. A. Oct. 4, 1946, No. 29602. [Class 112] A surgical suturing device comprises a hollow handle containing a suture-loaded spool and a feeding mechanism by which the suture can be fed or retracted through a hollow needle fixed to the handle. The feeding mechanism preferably includes a thumboperated roller. In the form shown, the handle is formed of two halves B 1 , B 2  hinged together at K and combining to form a hollow casing with a nozzle M over which the needle J is fixed. The nozzle is formed half in each part of the casing, and one half may have fixed in it a brass tube through which the thread passes. The thread-spool A rests in notches in the walls of the part B 2  of the handle, and is retained by a spring C which also controls its rotation. The thread passes between, and is engaged by, two rollers D, F carried by leaf-springs in the respective halves of the handle, the upper roller F being larger and projecting through a slot in the handle for engagement by the thumb : rotation of this roller feeds or retracts the thread.

Title: Improvements in aircraft
IPC: B64D27/06
Filed: 1936-11-02
Abstract: 486,759. Propelling aircraft. BRISTOL AEROPLANE CO., Ltd., and RADCLIFFE, J. M. Nov. 2, 1936, No. 29805. [Class 4] [Also in Group XXVII] A method of charging a supercharged internalcombustion engine, for aircraft, consists in heating the charge by compressing it to a pressure in excess of the pressure at which it is ultimately fed to the engine, passing the heated and compressed charge through a cooler, expanding the charge after it leaves the cooler to reduce its pressure to the desired supercharging pressure and thereby reduce its temperature still further, and then feeding the charge to the engine. An aero-engine 14 drives an air-compressor 20 having an intake 21 arranged below and near the front of the wing. Air is discharged from the compressor through a heat-exchange device 22 constructed as a radiator extending below the wing. Air passes from the device 22 through a conduit 23 to an expansion-nozzle 24 disposed in a chamber 25 formed in a pipe 18 connecting the engine carburetter with a perforated panel in the upper surface of the wing. Due to the extractor effect of nozzle 24 and chamber 25 air is drawn through the panel and supplied under pressure to the carburetter. The panel may comprise holes one sixty-fourth inch diameter and one quarter-inch pitch. The cooling radiator is designed to give minimum drag and may assist propulsion of the aircraft. The intake 21 may be dispensed with, the compressor drawing air through the panel. The compressor may replace the engine supercharger.

A sensing shoe 30 prevents locking of the reel under any circumstances until sufficient belt is withdrawn to permit buckling about a wearer. The cam plate 20 may carry a weight 23 to balance the assembly about its pivot point thereby ensuring that locking is responsive only to belt motion. Alternatively an unbalance may be provided to render the locking mechanism sensitive also to vehicle acceleration. The predetermined value of reel acceleration to which the mechanism responds may be adjusted by the tension of the spring 39, the ratio of the gears 25, 26 or by the value of a mass 27 integral with or keyed to the pinion 26.
