Patent GB-945233-A (GB)
Title: A circuit arrangement for keeping synchronous machines in step
IPC: H02P9/10
Filed: 1962-06-19
Abstract: 945,233. Automatic control. MASCHINENFABRIK OERLIKON. June 19,1962 [June 23, 1961], No. 23593/62. Heading G3R. [Also in Division H2] In an arrangement for preventing a synchronous machine 1, e.g. a generator, from falling out of step, a device 11 compares the current from two rectifiers 6, 10, the first of which is supplied with a quantity proportional to the voltage between two phases S, T and also a quantity proportional to the current in the third phase R; the latter quantity is also supplied, by itself, to the second rectifier. It is shown that by suitable adjustment of a resistor 3, capacitor 4 and inductor 5 the resultant current through device 11 can be arranged to reach zero when the displacement angle of the field is approaching the point of instability. Field strengthening in an unspecified way is then initiated. The point at which this zero current is reached can be made to correspond more closely to the instability point over a range of loads and power factors by providing different ratios for transformers 7 and 9, which supply the phase current quantity to the two rectifiers. If the machine may function either as a generator or a motor the capacitor 4 and/or inductor 5 are manually or automatically re-adjusted at change over. If the terminal voltage may fluctuate with load a corresponding correcting voltage is added to the inter-phase voltage by an additional current transformer connected across a resistor in the line supplying the voltage factor to rectifier 6 (Fig. 2 not shown). It is stated that the device 11 may be connected for comparing voltages instead of currents.

Title: A keyless device for winding up clockwork mechanism
IPC: G04B3/00
Filed: 1953-08-27
Abstract: 736,194. Clockwork winding devices. FRANCIS, B. F. Dec. 23,1953 [Aug. 27, 1953], No.23676/53. Divided out of 736,198. Class 10. [Also in Group XV] In a keyless clockwork winding device in which a spring is wound by the actuation of a withdrawable member, the power transmission between the member and the spring comprises a rotatable member movable axially along the spring shaft provided with a stop adapted to engage another stop fixed to the shaft rotation of the rotatable member by the withdrawable member in one direction, when the stops are in engagement, effecting winding of the spring, whilst rotation of the rotatable member in the reverse direction displaces the member axially on the shaft to disengage the stops. The parts of the device shown in Fig. 2 are in spring " unwound " position. To wind the spring the cable 17 is withdrawn to rotate the pulley 16 this rotation, through the stops 14, 18 and sleeve 12 to the shaft 10, energizing the main spring 11 and the torsion spring 20. On releasing the cable 17, the spring 20 causes the pulley to rotate in an opposite direction to rewind the cable as a result of which the pulley also moves back axially along the sleeve and disengages the stops 14, 18 (Fig. 1). The spring 11 can be held in the wound position by holding the shaft 10 or a part driven thereby. When this restraining pressure is removed the spring 11 drives the gear 15 and rotates the sleeve 12, the result of which is to move the pulley 16 axially back along the sleeve 12, bringing the stop 14 back into engagement with the stop 18, the parts then being ready for re-winding.

A carton for ice-cream &c. comprises a tubular cardboard &c. body 1, a bottom closure disc 7 which fits into the body and is retained by an internal rim 4 with a projection 5 engaging an annular groove 3 in the body, and a top closure disc 12 retained by a rim 9 having an inwardly projecting channel 13, the top of the body having a band 8 so that when the top closure disc is removed the rim 9 can be slid further downwardly until the upper margin of the body lies within the channel 13 to reinforce the open top. As shown, the lower edge of the rim 9 snaps over projections 11 on the band 8 to lock the rim in position. The body is scored to fold flat and the rims 4, 9 are of sheet metal. The upper closure disc 12 seats upon the top edge 12a of the body and the band 8 may be formed by bending over the top of the body as shown or a separate band may be secured to the body by staples or adhesive. The cover rim 9 has inwardly projecting lips 14 which engage under the lower edge 8b of the band 8 when the closure disc 12 is in place. When the closure disc is removed and the rim 9 pressed downwardly the lips 14 engage under the lugs 11 of the band 8. In a modification the lugs 11 are omitted and the rim held in the lower position by friction. Specification 675,014 is referred to.

Abstract: 385,567. High-tension switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Aug. 29, 1932, No. 24097. Convention date, Aug. 29, 1931. [Class 38 (v).] Switches, locking.-A switch of the type in which an explosion chamber 1 containing a fixed contact 2 is mounted in a vessel 5 containing water or other arc - extinguishing liquid, the level of which is above the opening in the chamber 1 through which the movable contact rod 6 passes, is provided with means for temporarily or permanently closing the opening, except for an annular space, after the passage of the contact rod 6 in the opening direction. In Fig. 1 this is effected by means of an extension 7 secured to the arcing contact 8 of tungsten or other refractory metal, the extension 7 being of ebonite, quartz, or material known under the Trade Mark " Micalex." The extension 7 may have a grooved surface to increase the insulation between the contacts, and may be arranged to move rapidly until the lower end reaches the hole in the chamber 1 and thereafter slowly, until, after the arc is extinguished, it moves completely out of the chamber 5.. Fig. 3 shows a means whereby it is ensured that the arc is extinguished before the hole is freed. At the point in the opening movement shown, the rod 6 engages a latch 10 which is controlled by a coil 12 carrying the current to be ruptured, the coil only allowing the latch 10 to be moved aside when the current therein is zero or very small. A resetting weight 13 prevents the latch from being moved aside at the zero of the A.C. cycle. In another form, an insulating rod under spring force follows up the rod 6 in its opening movement, Fig. 4 (not shown), and in yet another form, Fig. 5 (not shown), the rod 6 is tubular and surrounds an insulating rod fixed in the explosion chamber so that its end partly fills the hole therein. Excessive pressure within the chamber may be prevented by providing apertures therein, as disclosed in Specification 385,247.

A machine, for use with a potato harvester, for separating potatoes 'from stones, earth &c., delivers the mixture to the upper surface of a resiliently-surfaced drug rotating in a direction opposite to that of the feed thereto. The mixture from the harvester arrives on conveyer 4 and is fed on to a travelling belt 5 running on rollers 6 ... 10, of which roller 9 is driven. The material is slowed down by a flexible tongued apron 16, the position of which may be adjusted by .moving the transverse rod 17 in guides 18. The material may then fall on a plurality of flexible fingers 24 on its way to the separating drum 11, any rebounding material being caught by further flexible angers 25 and dropped through the gap between the fingers. The position of fingers 25 may be adjusted by mechanism 27 ... 30. The drum 11 ds rotated clockwise and comprises spaced longitudinal slats 61 around which is stretched rubber sheeting 62. Stones &c. falling on the drum are carried round thereby to fall to the ground while potatoes, being lighter and smoother, roll over the drum in the opposite direction. In order to effect a final separation of any remaining stones with the potatoes, the latter after retardation by flexible tines 31 fall on a shelf 12 and thence to a rapidly rotating roller 13. Roller 13 is wound with rubber cord and potatoes falling on it roll over a rubber check strap 14 and fixed bar 15 to a lateral conveyer, while stones are discharged through the gap between the roller 13 and shelf 12. Various adjustments for the position of the operative members of the separator are provided, Fig. 1 (not shown).
