Abstract: 674,886. Packaging machines. IVERSLEE CO. April 20, 1949. No. 10448/49. Class 94 (i). A packaging machine for enclosing a predetermined quantity of a commodity to be packaged in a pocket defined by two strips of material adhered face to face about the periphery of the pocket, comprises a roll having a peripheral portion for supporting and feeding a strip of porous packaging material, which roll is rotatable from a supply station at which a quantity of the commodity to be wrapped is placed upon the surface of the porous layer to a sealing station at which a second layer of packaging material is engaged upon the porous layer and adhered thereto to enclose the commodity, recesses spaced about the periphery of the roll, means for applying suction to the base of the recesses at the supply stations to draw the porous layer into substantial conformity with a recess thereat and, by suction, through the porous layer, to maintain the commodity in the recess during its passage from the supply station to the sealing station. A strip 11 of a porous wrapping material is fed over a peripherally recessed roll 6 rotated about a hollow horizontal shaft 7 and co-operating with an adjacent similarly recessed roll 9 and a superjacent rotary feeder 4. Suction applied to the base of the recesses 8 in the roll 6, from the hollow shaft 7 and through radial ducts 14, draws the strip 11 into a recess 8 below the feeder 4 and holds the powder fed thereto until the recess co-operates with a corresponding recess in the roll 9, where a strip 12 of non-porous wrapping material, fed over the roll 9, is sealed over and around the powder on the strip 11, with or without the use of heat. The so-formed chain package then passes around the roll 9 to the nip between it and a roll 23 where a third, non-porous, cover strip 22 is sealed on to the strip 11, and the individual packages severed by knives 26 on the roll 23. One edge of the strip 22 may extend beyond the corresponding edges of the strips 11, 12 to provide a flap 28, Fig. 5. In a modification, Fig. 6, a package chain 38 is formed from two porous strips 29, 30 and two outer cover strips 35, 36 of non-porous material sealed on to the chain of porous packets by recessed rolls 33, 34, individual packets being severed by a knife 41 or by cooperating blades and slots on the rolls 33, 34.

Abstract: 724,588. Transformers. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 20, 1953 [April 23, 1952], No. 10707/53. Addition to 696,346. Class 38 (2). [Also in Group XXII] A divided wound magnetic core for a transformer or similar apparatus is made by winding a ribbon of magnetic material onto a winding mandrel, the ribbon having been punched at every half-revolution of the mandrel to form a succession of transverse slots, each slot extending the greater part of the width of the ribbon, the distances between successive slots being varied so that adjacent slots, or groups of slots, on the wound core are displaced relative to one another to form overlaps of the ribbon, and removing from the wound core the marginal zones adjacent the slots so that core separates into two parts. Ribbon 1 is drawn from a storage reel through punching means onto a winding mandrel 4. A punch 9 is given an operative stroke every halfrevolution of the mandrel 4, by a cam 16 driven drom the winding mandrel, to punch a succession of transverse slits 2 in the ribbon, Fig. 1, leaving unpunched marginal zones 2<SP>11</SP>. The distance between successive slits is varied, so that the adjacent slits or groups of slits on the wound core are displaced relative to one another to form overlaps, Fig. 2a, by giving the punching means two superposed movements in the longitudinal directions of the strip. The punch tool 9 is supported by a member 6 slidable on a support 5 in turn slidable on the machine frame. The support 5 is given a continuous longitudinal movement, to compensate for increasing outer diameter of the wound core, by means of a screw 8 driven from the winding mandrel. The member 6 is reciprocated along the support 5, to give the relative displacement of adjacent slits on the wound core, by a cam 11 also driven from the winding mandrel. After winding, the core may be heat treated and impregnated. The marginal zones 2<SP>11</SP> are removed by grinding, sawing or milling so that the core is divided into two parts.

Abstract: 126,305. Odhner, V. J. May 1, 1918, [Convention date]. Transfer mechanism. for calculating-machines of the pin-wheel and cam-disk type, consists in the arrangement of the slotted rocking arms cooperating with the usual laterally movable transfer pins, and in the construction of the fer pins, and in the construction of the cam-part of the arm which actually engages the transfer pins. The pivot 8 of the arm 7 is arranged on the bisector of the angle between tangents a b, c d drawn to the pin-wheel 1 at the points at which the transfer pins 2, 3 engage the cam-part 9 of the arm 7. This arrangement is for the purpose of reducing to a minimum the tendency of the transfer pins to throw the arm out of its operative position. The cam-part 9 of the arm is formed as part of a cone, the apex of which is the centre of the disk 1, to afford a large bearing-surface to the pins 2, 3.

Filed: 1944-06-07
Abstract: 584,942. Wave guides. FERTEL, G. E. F., and WRIGHT, C. S. June 7, 1944, No. 10956. [Class 39 (i)] In a wave guide 2, attenuation of highfrequency electromagnetic energy is effected by the ionisation of gas in a gas-discharge tube 1, in which each electrode 3 and the leads 4 supplying current thereto lie in a plane parallel to the H plane of the guide. The amount of attenuation can be varied by varying the current passing through the discharge tube. To reduce persistence of attenuation after the current supplying the discharge has been interrupted, a tube is chosen which rapidly recovers from ionisation. Either the electrodes are arranged close to the glass envelope, or alternatively by introducing into the envelope insulating obstacles, or molecules, for example water vapour or carbon monoxide, which reduce the lifetime of free electrons.
