Title: Capacitor manufacture
IPC: H01G4/22
Filed: 1973-06-06
Abstract: 1468511 Capacitors JOHNSON & PHILLIPS (CAPACITORS) Ltd 31 May 1974 [6 June 1973] 26966/73 Heading H1M In a method of manufacturing a liquidimpregnated capacitor by winding together strips of electrode material and substantially non-porous strips of dielectric material, not all of the strips are wound at the same tension, whereby transverse corrugations are formed providing axial passages through the capacitor roll and aiding impregnation. The electrode strips may be wound at different tensions from the dielectric strips, in particular the dielectric separating adjacent electrode strips may comprise three strips, two of which are wound at the same tension, the third at a different tension. The different tensions may be obtained by appropriate braking of the supply rolls from which the strips are drawn off and fed to a mandrel. Alternatively the strips may have been wound on to the supply rolls at different tensions and even when wound into a roll at the same tension the desired corrugations are formed. The dielectric film may be polypropylene and the impregnant mineral oil. Electrodes of opposite polarity may be offset for end-face contacting and may be formed by metallizing dielectric strips.

Title: Self releasing drive for power transmitting mechanisms
IPC: A01D34/30
Filed: 1955-09-26
Abstract: 831,948. Mowing machines. DEBENHAM, G. E. Sept. 19, 1956 [Sept. 26, 1955], No. 27390/55. Class 6(3). A reciprocating mower bar is driven in such a a manner that in the event of an obstacle's being entrained in the knife the latter stops but the drive to the knife continues and subsequently drives the knife in the opposite direction to release the obstacle, after which the knife is reciprocated in the normal manner. The mower bar 27, shown in Fig. 1, is mounted at one end of a connecting rod 24 pivoted at 25 to the frame of the mower and carrying at its other end a mounting block 21 formed with recesses on its opposite sides for balls 19 and 20. Guide members 11 and 12, fixed to a member 10 which is reciprocated from, for example, a tractor, are formed with grooves 17 and 18, the latter being further formed with a recess 23 for the reception of the ball 20. The guide members are normally urged together by springs 15 and 16, and as the member 10 reciprocates, movement of the balls 19 and 20 in the recess 23 and groove 17 respectively allows the connecting rod to pivot about the fixed point 25, thus reciprocating the knife 27. When an obstacle becomes lodged in the knife, the ball 20 is forced out of the recess 23, the guide members 11 and 12 moving apart against the action of the springs 15 and 16, so that whilst the knife remains blocked by the obstacle the guide members 11 and 12 complete their stroke. As the guide members begin their return stroke, the friction arising from spring pressure between the balls 19 and 20 and the grooves 17 and 18 respectively is such that drive is once more transmitted to the connecting rod 24 although the ball 20 is still disengaged from the recess 23, the obstacle being freed from the knife during this return stroke. During normal operation the connecting rod 24 does not contact either of the stops 28 and 29 which are provided, but once the ball 20 is spaced from the recess 23 this is not the case, and during the reverse stroke mentioned above the motion of the connecting rod will be arrested by one of the stops, whilst the stroke of the guide members 11 and 12 continues, thus providing an opportunity for the ball 20 to be reseated in the recess 23, after which normal reciprocation of the knife will be resumed. The construction maybe modified as shown in Fig. 2, in which the mounting block 38 is fixed to two members 40 and 41 which are in turn fixed to the knife-carrying member 31, the members 40 and 41 being capable of movement relative to the driven member 30. Alternatively, the construction may be as shown in Fig. 3, in which the members 10, 51 and 52 are normally reciprocated, the connection between the members 51 and 52 comprising a ball 54 carried by the member 51 and seated in a recess in the member 52. Specification 777,590 is referred to.
Patent GB-499523-A (GB)
Title: Improvements relating to indicating apparatus for use in gun control
Filed: 1937-10-08
Abstract: 499,523. Gun control. EVERSHED & VIGNOLES, Ltd., and SHORT, W. J. Oct. 8, 1937, No. 27437. Addition to 474,293. [Class 92 (i)] The model-switch endangering-preventing apparatus according to the parent Specification is now modified by providing means whereby the amount of relative sliding movement of the elevating contacts e, f, of the model switch, produced by a given change in the relative trainings of the guns, is reduced with increase of the elevation of the endangered gun B. In the construction shown, the toothed sector f<3>, which carries the contact f, is mounted on a carriage m which is slidably mounted on a rod m<1> under the control of a spring n. Movements of the carriage are effected by a cam k, the shaft of which is geared to the motor Tb which repeats the training movements of the turret B. The cam k is tapered and is slidably mounted upon the shaft j, its position being controlled by a system of levers v, y, driven by a shaft f<2>. The latter is geared to a motor Eb which repeats the elevating movement of the turret B. The arrangement is such that when the guns of the turret B are highly elevated, the cam is so positioned by the motor Eb that it imparts a greater movement to the carriage m than when the guns are at a lower elevation. The other details of the switch are substantially the same as those of the switch described in the parent Specification. In a modification, the cam is replaced by a pivoted lever, one end of which is connected to the carriage m and the other end to a wheel geared to the motor Tb. The centre portion of the lever is slotted to receive a pin about which the lever pivots, and the pin is carried by a pivoted lever which is connected by links and gearing to the shaft of the motor Eb. Thus, when the motor Eb is driven the position of the pin is altered thereby varying the effect of the lever upon the carriage m.
