Title: Improvements in Dynamo Electric Machines.
Inventor: CHASSIN MARIUS
IPC: H02K7/104
Filed: 1919-05-08
Abstract: 126,644. Chassin, M. May 11, 1918, [Convention date]. Machines with two or more armatures; dynamos, regulating; motors, controlling; cores and yokes.-A rotating member a additional to the armature c is introduced into the magnetic circuit of a dynamo or motor and bv its rotation in the magnetic flux passing through it produces eddy currents which tend to diminish the flux. The member a may be secured on the armature shaft, or it may be separately driven by another machine, the speed of which varies according to the voltage. The member. a and the adjacent periphery of the field magnet b may be provided with slots, tunnels, or windings. A portion only of the total flux of the machine may pass through the member a which may act as a brake to steady the speed. The invention is applicable to dynamos for motor-car lighting.
Patent GB-754567-A (GB)
Title: Improvements in or relating to devices for fluidising solid materials
IPC: C10B49/10
Filed: 1954-04-21
Abstract: A device for the fluidization of a mass of a particulate solid comprises a vessel 10 (Fig. 1) having a perforated grid 13 supporting the solids and spaced from the base of the vessel to form a chamber 15 into which a gas having a pulsatory flow is introduced, the sides of the vessel having projections 17 to prevent passage of the fluidizing gas up the walls of the vessel. In a modification perforated side walls are provided in the vessel, these side walls being surrounded by an extension of the chamber 15.  In a further modification a series of cellular partitions of honeycomb shape are arranged above the perforated grid of the vessel.  The vessel containing the solids may also be joined to <PICT:0754567/III/1> <PICT:0754567/III/2> a base member by means of a flexible bellows and the vessel is connected to a mechanism which gives it a series of vertically-directed shocks.  Any suitable means may be provided for giving to the gas a flow of a pulsatory character, e.g. the alternate opening and closing of a damper in the delivery duct of a fan or by means of a volumetric fan having the two rotors geared together so as to give a pulsatory output.  In a further modification (Fig. 5), the vessel 41 containing the solids is cylindrical and below the perforated grid 40 is arranged a piston 43 which is connected by a link mechanism to an eccentric 52 so that the piston is moved up and down in the free space below the grid 40.  The piston also has a series of flap valves 44.  During upward motion of the piston the flap valves are closed and gas between the piston and the grid 40 is forced upwardly through the bed of solids 16 to fluidize the solids. When the piston is retracted the flap valves 44 open and further fluidizing gas enters the free space below the grid.  The apparatus may be applied to the gasifying of coal, in sorting fine particles from larger particles, or in causing gases to enter into a catalytic or chemical reaction with the solids fluidized.

Title: Improved knitting method and apparatus for terrying yarn
IPC: D04B1/02
Filed: 1960-04-01
Abstract: 917,353. Knitting. FARMER, G. R. April 1, 1960 [April 3, 1959], No. 11635/60. Class 74 (2). A verge assembly is provided in the lower end of the upper cylinder of a superposed cylinder machine and comprises a dial 45 containing bits 63 adapted to be actuated in sequence with the needles to enable terry loops to be drawn over their ends. Sufficient terry bits 63 may be provided to enable terrying to occur in the heel and sole portions of a sock whilst non- terrying bits 64 are provided over the remainder of the needle circle. The result is that the terry yarn slips off the ends of the bits 64 to be knitted in normal plating relationship with the ground yarn during production of terry fabric with the terry bits 63 but that both bits 63, 64 are capable of functioning as knock-over bits of any loops drawn by the needles in the upper cylinder. The dial cam cap is provided with a cam groove having two bit advancing portions 73b with a bit retracting portion 73c coupling them. The cam cap can be placed with the portion 73c opposite the yarn guides so that the bits are operated in each direction of reciprocatory knitting to effect the formation of terry loops. Also, by displacing the cam cap the bits can be rendered inoperative in that they are withdrawn and advanced during needle draw so that the terry yarn passes beneath them and is knitted in plating relationship with the ground yarn without forming terry loops. U.S.A. Specifications 2,450,376 and 2,435,770 are referred to.

Title: Improvements relating to sewing machines
IPC: D05B69/18
Filed: 1953-04-29
Abstract: 732,295. Sewing-machines. SCHWAB, M. April 29, 1953 [April 30, 1952], No. 11823/53. Class 1.12. The direction of stitching in a sewing-machine is reversed by means of an electromagnet, preferably controlled by a knee-lever and acting on the usual feed-control means. The invention is described in connection with a machine having an auxiliary slow-speed drive automatically brought into action before stopping, and provision is made for sewing a few stitches forwards and then backwards before stopping, to secure the end of a seam. In the arrangement shown, an auxiliary electric slow-speed drive circuit is connected to terminals 28, and power is applied to terminals 30 automatically when the main drive is put out of action by a control treadle which also actuates a selector switch 15 to determine whether power is fed to the auxiliary drive from the upper or lower contact of a switch 14 rotating with the machine, one of these contacts being opened when the needle of the machine is in its upper position and the other in the lower. When slow-speed stitching is required before stopping, the rotary switch 19 is moved clockwise by means of a knee-lever to the position shown, which is determined by a detent 191 engaging a notched disc: in this position the contacts 22, 23 are connected so that the auxiliary drive is fed from both contacts of the switch 14 and therefore runs continuously until the rotary switch 19 is moved another step, when the machine stops. A further step of the switch results in energization of the feed-reversing electromagnet 35 through contact 33, and restarting of the continuous slow drive by the contacts 24, 25. The switch is returned to its initial position by a spring 37 when released. The electromagnet 35 may be connected to the feed-reversing lever directly or by a chain or cable passing round a pulley.
