Title: Improvements in or relating to an output regulator for the distribution of electric energy
IPC: H02P9/00
Filed: 1924-02-23
Abstract: 211,890. Hesse, E. Feb. 26, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Boosting. - The distribution and storage of electric energy in plants in which a dynamo 1 is driven by variable power such as a wind-motor is regulated by connecting the dynamo 1, a storagebattery 4 and a current consuming device 3 in parallel with bus-bars 2 the storage battery being charged by means of an auxiliary dynamo 5. The auxiliary dynamo 5, which is arranged in series with the battery 4, is driven by a motor 6 and produces the additional voltage, if required, for charging the battery 4. A voltage regulator 7 is provided for the auxiliary dynamo 4 and is so arranged that if the voltage across the bus-bars falls owing to a diminution of power, resistance is switched into the field-circuit of the auxiliary dynamo and the battery-charging current diminished; if the power rises, resistance is cut out from the auxiliary dynamo field circuit and the batterycharging current.increased.

Abstract: 1377525 Igniters for burners VOLCANO CO Ltd 1 Feb 1972 [12 Aug 1971] 4768/72 Heading F4F Apparatus, Fig. 1, suitable for igniting a burner comprises an element 3 of a material such as carborundum mounted in a carrier 7 provided with electrical contacts L1, L2 for applying a voltage across the element, a transformer 10, Fig. 2, controlled by a switch 11 for selectively applying a lower and a higher voltage across the contacts, and a current relay device 13 responsive to the current flowing between the contacts and adapted to actuate the switch 11 to change the voltage across the contacts from the higher to the lower voltage when the current detected by the device 13 rises above a predetermined value. The element 3 is mounted between a removed cap 1 and a member 5 within an apertured tubular member 2. The switch 11 is initially connected to the intermediate tap Ta of the transformer so that about twice the input voltage at 8 is applied to the element 3 to heat it immediately to about 800 C. The current in the secondary circuit detected by the relay 13 rises then to a predetermined value at which the relay operates the switch to connect to Tb. The input voltage at 8 is thus applied across the element 3 and in one or two seconds, Fig. 4 (not shown), the element 3 reaches about 1600 C., the burner igniting temperature.

Abstract: 1,253,976. Razor blade dispensers. WILKINSON SWORD Ltd. 7 Nov., 1968 [8 Nov., 1967; 31 Jan., 1968], Nos. 52043/68 and 4862/68. Heading B8P. [Also in Division F2] A razor blade dispenser has a body 12 and a lid 11 which is slid leftwardly to project a blade through a slot 37. from a resiliently mounted stack of blades 22, by means of a ridge 13. During ejection the blades are resiliently biased by a spring assembly comprising members 19 and projections 20 which are pressed into position by a cam 25 integral with the lid. When ejection is completed the cam disengages from the member 19. Using a cam to bias the spring permits the use of synthetic resins for the spring which, if permanently stressed, would take up a permanent set. An aperture 44 provides access to a used blade compartment 43. The cam may be of different shape or as an alternative it may be omitted and the blades continuously biased. In another embodiment the blades are resiliently mounted by plastics foam and a spring returns the lid to its original position after the blade is ejected.

Title: Process and apparatus for liquid treatment of hats and analogous articles
IPC: D06F17/06
Filed: 1933-02-21
Abstract: In the liquid treatment of hats or like articles, the treatment liquid is caused to flow through a perforated stationary vessel containing the articles, and the positions of the inlet and outlet conduits of the liquid supplying means are caused to move so that the regions through which the liquid enters and leaves the vessel are displaced on the surface of the latter.  Preferably the area of the surface of suction is large compared with the area of the surface of delivery.  In Figs. 1 and 2, the articles to be treated are placed in the vessel 1 having a perforated bottom 3. Beneath the perforated bottom and in contact with it is a hollow piece 4 having a rectangular opening 5 at its upper surface.  The lower portion of this hollow piece 4 contains a helico-centrifugal pump 8 which draws liquid through the circular lower opening 7 of the hollow piece, and discharges it out through the upper rectangular opening 5.  The circular opening 7 is open to the conical portion 2 and thus in communication with the two approximately semi-circular portions abc and def, of the perforated bottom 3.  The pump 8 is caused to rotate at a suitable high speed, while the hollow portion 4, attached to the hub 11 and the hollow hub 17, is caused to rotate more slowly by means of the worm wheel 18 and worm 20, and the further worm wheel 21 and worm 22.  By this means the rectangular slot 5 is caused to rotate slowly on the perforated bottom 3, and by the action of pump 8, the treatment liquid is forced into the vessel 1 by way of the slot 5 and withdrawn through the two portions abc and def.  The apparatus of Fig. 3 comprises a rectangular vessel 40 divided longitudinally by a wall 43 which does not reach the bottom.  The portion of the vessel bounded by the walls 41 and 43 is provided with a perforated bottom 44.  In the other portion of the vessel is fitted a pump 45 driven by a motor 46 supported on rods 50 and a screwed rod 55 so that the pump and motor <PICT:0407520/IV/1> may be moved as a unit from one end of the vessel to the other, means being provided to cause the unit to oscillate automatically between these positions. The pump 45 delivers into a passage 51 having a rectangular opening in contact with the perforated bottom 44.
