Class 51 (1). [Also in Group XXVI] Combustion apparatus which may be mounted in a duct or box through which air is passed in order to heat the air, comprises a rotary combustion chamber a to which combustion air is admitted through a disctype valve p responsive to pressure fluctuations in the chamber. The air is stored in a chest m which is secured to the chamber and mounted for rotation with it on a hollow shaft b extending between bearings c. Combustion air passes to the chest m through the shaft b and perforations therein. Fuel is supplied to the chamber a through a a pipe and nozzles e. Ignition is effected electrically by electrodes g to which current is conducted through brushes i, slipring j and the shaft, cable k and an insulated part h of pipe f. Rotation of the apparatus is effected by causing the combustion products to pass along pipes q and issue through nozzles so disposed that they discharge tangentially to a circle containing the nozzles. The air chest m may be omitted and the combustion air admitted through the valve directly to the chamber a from the atmosphere. Liquid fuel may be supplied from a carburetter in which case the fuel flow to the nozzles is induced by the pulsating pressure condition in the chamber a.

Abstract: 279,972. Toyoda, K. Aug. 26, 1926. Shuttle-changing mechanism.-When the welt is exhausted &c., a rod 15 raises a member 14 into the path of the lay whereby an arm 13 and shaft 12 are rocked. An arm 16 acts on the arm 6 of a lever 7 pivoted at 5 and carrying the shuttle box front, whereby the lever 6, 7 is rocked against the action of a spring 26, so that the front 3 is raised to allow a fresh shuttle to be introduced into the shuttle box from a magazine 8 by means of an ejecting rod 9 connected by a link 10 to an arm 11 on the shaft 12. Picking-motions; checking pickers.-The arm 6 engages an arm 19 on a vertical shaft 18, whereby this shaft is rocked against spring action and inner and outer levers 20, 21 on the shaft are rocked outwards. The outer lever 21 is thus moved into position to release the check strap 22 whilst the inner lever 20 pushes the picking arm 25 and picker outwardly. A gap is thus produced between the picker and the shuttle, so that the latter can readily be removed.
Patent GB-358940-A (GB)
Title: Improvements in the activation of carbonaceous materials by gases
IPC: C01B32/336
Filed: 1930-07-11
Abstract: <PICT:0358940/III/1> Activation of carbonaceous material is effected by subjecting it to a series of alternate heating and activation phases until the desired degree of activity is attained; the furnace or retort containing the material is heated internally and externally by the combustion of heating gases, the activation being effected by gases differing in composition from the heating gases.  As activating gases, oxygen, superheated steam and/or carbon dioxide may be employed to which chlorine or hydrogen chloride may be added.  The gases produced during the activation stage may be used as combustion gases for heating purposes.  In operation, the heating gases are passed through a pipe a into a chamber F where they are burnt and the products of combustion pass into a chamber L containing activation retorts having porous or apertured walls, air for combustion being admitted by a pipe b.  The pipes a, b are then closed and superheated steam is admitted by the pipe c to the combustion chamber F where further superheating is effected before the activation chamber L is reached.  After the temperature in the chamber L has fallen to the minimum allowable, the pipe c is closed and a, b are opened to commence a second heating stage which is followed by a second activation stage and so on until the desired condition is reached. Gases from the activation stage may pass from the chamber L by a valved pipe f to a gasometer whence they may be withdrawn for heating purposes.  The waste heating gases may pass by a pipe d to a flue or by a pipe e to a heat recuperating apparatus; a little air may be mixed with these gases to allow complete combustion to be effected prior to their utilization.  In an example beechwood charcoal when activated with steam requires that the limits of temperature lie between 500 DEG  and 600 DEG  C., more specifically 530-580 DEG  C.; with carbon dioxide the limits are 800-880 DEG  C.  By the addition of chlorine or hydrogen chloride, these limits may be lowered; the amount added should not be such as to interfere with the combustibility of the gases produced.

In an electrical system for the identification of mobile objects, each of which has a pick-up circuit and an oscillator of distinctive frequency, a transmitter and selective receivers responsive respectively to said oscillators are placed in proximity to the path of said objects, each of the pickup circuits receiving energy from said transmitter when near it and providing sufficient direct current to remove its associated oscillator operative for a time ending later than that in which said pick-up circuit is near said transmitter. The mobile objects may be, for example, trams or railway coaches. The radiated energy which is of mains frequency is picked up by circuit L 1 , rectified at RE, smoothed, and powers a transistor oscillator having coupled windings on a ferrite core in the collector and base circuits, the collector circuit being characteristically tuned by capacitor C. In order to recognise the direction of travel of the object, it first passes through a 50 c/s. field before passing the receiver and thus the latter will react immediately, whereas if the direction is reversed the object will not react until after it has passed the receiver's immediate vicinity.
