Title: Improvements relating to the determination of unbalance in rotors
IPC: G01M1/22
Filed: 1945-08-23
Abstract: 615,899. Determination of rotational unbalance. AKTIEBOLAGET NORDISKA ARMATURFABRIKERNA. Aug. 23, 1945, Nos. 21615, 21616 and 21617. Convention dates, Aug. 24, 1944, and July 12, 1945. [Class 40 (i)] [Also in Group XIX] Means for determining the unbalance in a rotating body comprises a pair of transducers responsive to the vibrations in two spaced planes of the rotating body, the transducers being connected in series to a current-measuring device. A motor 4 drives the rotor 1 to be tested, in bearings 2, 2<SP>1</SP>, supported on plate springs 3, 3<SP>1</SP>, whereby the horizontal vibrations of the bearings are transmitted to electromagnetic pick-ups 7, 7<SP>1</SP>, having direct current energization and a supplementary circuit in the core, supplied with alternating current to overcome remanence. The measuring coils of the pick-ups are connected in series to brushes 16, 17 in a rotatable brush holder 15 connectible through a commutator for half a revolution with brushes 18, 19 and for the other half revolution with brushes 19, 18, respectively, or alternatively with brushes 20, 21 and 21, 20, respectively. After adjustment of potentiometer 10-13 to vary the relative energization of the pick-ups, the angular position of unbalance in one plane 14 is determined by putting switches 9, 22 in the positions shown and rotating the brush holder 15 until, with the rotor rotating, the reading of the ammeter is zero. The amount of unbalance is then shown on the ammeter 23 by reversing the switch 22. The rotor is then stopped in an angular position determined by the position of the brush holder and a correcting weight can be added. The process is repeated for the plane 14<SP>1</SP> by reversing the switch 9.

Abstract: 706,019. Making bags or pouches. ARMELIN, E. R. Aug. 27, 1951 [Sept. 6, 1950], No. 21984/50. Class 94 (2) Bags or pouches for tobacco &c. particularly expendible pouches for retail sale, of the type having a front and back portion, and a flap extending over part of the front portion are made, by folding a rectangular blank of sheet material, e.g, laminated plastic sheet and metal foil, parallel to one pair of opposite sides to form the front and back portions and flaps, and edge-folding at least twice parallel to the other pair of opposite sides for closing the sides of the receptacle body by embracing the front or back portion by a marginal edge of the back or front respectively, and for stengthening the corresponding edges of the flap. A web 46 is cut by knife cylinder 49 to sever sufficent material to form one pouch, which passes to gumming wheels 55 which apply lines of gum g, h, j-, :k, Fig. 1. Folding rollers 60 and a beater 61 make a fold on the line l, m. Plough folders 65 then fold over the edges n, o and the pouch passes to heaters 67 and compressing rollers 69. The pouch then enters the grip of two pairs of bands 70 and passes below gum wheels 72 to form gum lines p, q. Fig. 3. Plough folders 77 then turn up the folded edges producing the double folds r, s, Fig. 4. The pouch then passes between heaters 80 and compressing rollers 82 and the finished pouches are delivered on to a conveyer band 83 in stepped formation. When using heat sealing web no gumming 4s necessary. Figs. 7 and 10 show a modification in which the web of material is of width equal to that dimension of the pouch which is perpendicular to the main fold x-x and the pouch has a narrow flap v. In this form the web is first formed with edge folds v, w while reinforced threads t. u are fed into these folds, which are then sealed. The blanks are then severed and folded along the line x-x offset from the centre so as to expose the whole of the fold v, which is then folded down again to form the flap. The side edges are then gummed, folded, compressed, gummed again, re-folded and re-compressed to form the double side folds y, y. The purpose of the threads t, u is to reinforce the lips of the pouch. The Provisional Specification describes also a form of pouch and a machine for making it in which slits are made in the blank at the ends of the main fold and the edges of the flap folded in, the blank folded at the main fold and the edges folded around the previously-folded edges of the flap.

Abstract: 378,203. Feeding sheets &c. HODGSON, W. and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Aug. 10, 1931, No. 22550. [Class 100 (ii).] Tripping-arrangements.-A sheet detector device, which is applied in connection with the feeding of coupons 1 to cigarette packets C, comprises a pivoted feeler 10 arranged in the path of the coupon as it is being conveyed by bands 7, 8 to the packet C. The feeler 10 is integral with a lever arm 13 formed of a flat spring, and the arm 13 rests by gravity against a screw 12 which is adjusted so that normally a single coupon can pass under the feeler 10 without moving the arm 13. If, however, two coupons are fed, the lever 13 is caused to engage an adjustable electric contact 14 and the circuit is completed to an alarm bell 15 which warns the operator. In a modification, the arm 13 is arranged close to a second contact which it engages when no coupon is fed, so that an alarm is sounded if no sheet is fed or if two sheets are fed. A rotary switch in the circuit of the alarm bell permits the circuit to be closed only at the time when a coupon should normally be passing the feeler. The apparatus may be combined with mechanism such as described in Specification 357,970, [Group XVII], for rejecting defective cigarette packets.
