Title: Improvements in or relating to suction cleaners
IPC: A47L9/10
Filed: 1945-01-25
Abstract: 584,825. Vacuum cleaners. HOOVER, Ltd. Jan. 25, 1945, Nos. 2010 and 2011. Convention dates, Jan. 28, 1944, and March 23, 1944. [Classes 8 (i) and 8 (ii)] In a suction cleaner comprising an initial dust separator 15 shown as a whirl chamber and a final separator or filter 57 cleaned by a nozzle 66 which receives its suction from the initial separator and delivers the collected dust thereto during a filter-cleaning period, the motor has two rotating parts, e.g., the rotor and stator one of which drives the fan 19 and the other drives the filter-cleaning nozzle. The motor shaft is supported by a bearing 38 in a double wall 13 separating the fan and motor, and a second bearing 39 on the motor frame casing 41 which is rotatably carried by a bearing structure 47 on the wall 13; current is supplied through a switch 53. Air which has passed through the filter flows out through ports 61 in a second wall 14 and an exhaust port 62 in the cover to which port a blowing tool can be connected. The casing 41 is supported at its rear end by the conduit 67 of the filter nozzle, rotatable in a bearing, and its rate of rotation is slowed down by a gear 77 engaging a gear 78 on a shaft which through linkage is caused to oscillate a vane, having a small aperture, within a casing 89 containing air or liquid, and constituting a dashpot. Normally rotation is prevented by a pin engaging the gear 77, but when by the rise of pressure within the filter a diaphragm is actuated, it releases this pin, and at the same time opens a valve 74 to connect the nozzle with the conduit 73 leading to the first separator 15. The release of the pin allows rotation of the stator and the initial movement is caused to release a spring switch to increase the motor speed by cutting out a part of the field winding. In another form, reduction gear is provided between the frame 41 and the filter nozzle. In a third form, current is conveyed to the rotatable stator by coil springs attached to the stator and to fixed terminals, and in normal operation the springs hold the stator against rotation. When the diaphragm within the filter is moved by rise of pressure due to clogging of filter, it operates a switch to move the' motor connections to high-speed position in which the stator is rotated winding the springs, the switch being returned to low-speed position by a pin on a rotary part controlling a solenoid circuit to limit the cleaning movement to a single complete rotation. A piston dashpot contrcls the speed of the filter cleaning nozzle.

Abstract: 328,305. Boughton, E. B., Emmott, W., and Brock, D. T., (trading as Automotive Products Co.). Jan 25, 1929. Fluid-pressure. - Relates to fluid-pressure braking systems more particularly for motor vehicles of the kind comprising two separate systems each complete in itself but operated by a common lever and connected by a balancing device which ensures equal pressures in the systems and which, should one system fail, ensures the other system remaining operative. The balancing device comprises a piston 17 centrally arranged in a cylinder 12 communicating at opposite ends with the two systems, stops 19 limiting the axial movement of the piston. The front wheel brakes of a vehicle are operated by a pressure producing unit 8 by means of a pipe 7 and the rear wheel brakes by a unit 10 and by means of a pipe 9. Both units are operated by a lever 11. If one system fails the piston 17 moves over until it abuts against one or other of the stops 19, and the unaffected system will then function normally and the whole of the pressure applied to the lever 11 will be applied to this system only and not be divided between the two. More than two brake systems may be employed. Specifications 280,502 and 298,100 are referred to. According to the Provisional Specification more than two brake shoes may be associated with each wheel and connected to separate systems or two or more pressure-operated devices may operate each brake shoe and are connected in different systems. Each system may operate the brakes on one diagonally arranged pair of wheels.

Title: Process for the production of high molecular weight linear polyesters from diol esters of terephthalic acid
IPC: C08G63/84
Filed: 1952-02-01
Abstract: Hydroxyl-terminated esters from terephthalic acid and ethylene glycol are converted to high molecular weight linear polyesters by condensation in the presence, as catalyst, of boron trioxide. The chain length of the polymers may be limited by the addition for example of a mono-carboxylic acid.  In the example terephthalic acid diglycol ester is fused with added boron trioxide and propyl benzoate and heated in an atmosphere of nitrogen until splitting off of glycol ceases.  The pressure is then reduced and heating continued and maintained for half-an hour after reaching a temperature of 270-280 DEG  C.  The molten condensate is forced from the vessel by nitrogen pressure and cooled in water.  The polymer is shredded, washed, dried and spun into threads.
