Title: Machine for wrapping groups of articles
IPC: B65G47/71
Filed: 1967-01-12
Abstract: 1,117,173. Wrapping groups of articles. PLATMANUFAKTUR A.B. 12 Jan., 1967 [24 Jan., 1966], No. 1768/67. Headings B8A and B8C. Articles, such as cans, delivered in single file by an endless belt conveyer are formed into a rectangular group which is then moved (Fig. 8) into a web of material, formed by joined web portions fed from above and below, so that the web is folded about the articles to be sealed, and cut off behind them and then, at a subsequent station, the open ends of the tubed web are sealed. Feeding and marshalling the cans.-The single row of cans is first divided into two rows by a recessed wheel 5 (Fig. 2) and are subsequently separated by a partition 13 which may carry a roller 14 at its leading edge. Each row so formed is fed to a recessed wheel (Fig. 4, not shown), the recesses in which vary in depth to divide the supply of cans between three compartments 22, 23, 24. By this means a batch of cans is formed against a stop 31 (Fig. 9) and, when this @ is complete, the compartments and cans @ together over a bridge 35 to a further endless conveyer 36. Combs 55 which move with the compartments, and also have a vertical movement, control the movement of the cans. In an alternative construction (Fig. 16, not shown), two rows of cans are fed to opposite sides of an assembly plate (99) on to which three cans at a time are pushed from each side by pushers (100) until the batch to be wrapped is completed. The batch is then pushed from the assembly pate by a pusher (109) on to the wrapping conveyer. Wrapping; sealing wrapper; conveying partly wrapped packages.-As the completed batch and the compartments 22, 23, 24 holding it are moved simultaneously on to the conveyer 36, they engage a pair of joined wrappers, one extending from a roll above the machine and one from a roll below. During this movement the cans are engaged by combs 55 lowered behind the batch, and the wrapper is initially engaged by fingers 62, 63 moving with the compartments. After the wrapper has thus been formed for the position shown in Fig. 9, yokes 68, 69 are moved to surround the batch of cans and the compartments are retracted, together with the combs 55. The wrapper is then sealed and cut behind the batch (Fig. 11, not shown) before this is moved, together with the yokes 68, 69 to a second sealing station. At the second station the yokes 68, 69 are retracted and fingers 76, 77 (Fig. 12) are inserted in the open ends of the wrapper to hold the edges together for sealing. The edges may also be closed by jets of air. In an alternative construction (Fig. 20, not shown), the fingers 76, 77 are pivoted for movement in a plane transverse of the conveyer on arms turned about axes transverse to the conveyer. Shrinking the wrapper.-The wrapper is subsequently shrunk by hot air ducts (Fig. 15, not shown).

Filed: 1941-02-11
Abstract: 544,323. Herringbone gears. NATIONAL BROACH & MACHINE CO. Feb. 11, 1941, No. 1876. Convention date, March 25, 1940. [Class. 80 (i)] [Also in Group XXII] In finishing herring bone gears, the gears are provided with point-crotch clearance and material removed by a shaving operation for a distance extending inwardly from the outer ends of the teeth. In one form, Fig. 1, taper teeth are first formed in a shaper operation so that there is a point-crotch clearance P.C. of 0.002 inches. The gear is then run with one half G in mesh with a conjugate gear like shaving tool T, arranged in crossed axis relationship the shaving being continued to a point 22 adjacent the crotch so that a pair of finished gears mesh as shown in Fig. 2 and the crotch clearance is reduced. In some cases a crowned form may be imparted to the teeth by oscillating the cutter about the common normal to the gear and cutter axes to obtain teeth which engage in the manner shown in Fig. 3. Or the crowning may be produced by rocking about an axis transverse to the gear axis and lying in a plane parallel to the gear and cutter axes. The contact is then confined to the regions 32 of the two parts of the gear. In another modification Fig 4 non- modified teeth may be shaved by means of a modified cutter which has the corners 42 of its teeth removed the cutter being oscillated about the common normal of the gear and cutter (centre 43) so that it removes metal from the point side at the other end. If desired the oscillation may also be carried in the other direction. The centre 43 may be shifted to vary the amount of metal removed from the respective tooth surfaces. In another modification the teeth may be first cut to different leads, Fig. 9, and then the teeth 91 shaved to relieve the points 92 and to remove metal from the outside corners on the crotch side. If desired only one member of a mating pair may be finished and the effect of crowning obtained.

Abstract: In the separation of straight-chain compounds from their mixtures with branched chain and/or cyclic compounds by contacting with an aqueous phase containing dissolved urea or thiourea to form crystalline complexes with a fraction of the mixture, a water-soluble salt is dissolved in the aqueous phase to suppress emulsification. Suitable salts, which are used in amounts of 0.1-5, generally 0.5-2.5 per cent by weight of the aqueous phase, are alkali metal or organic nitrites, chromates, and iodates, e.g. the sodium, potassium, lithium, dicyclohexylamine, di-isopropylamine, piperazine, morpholine, tri-tert.-butylamine, trimethyl - benzyl - ammonium, and tetraethyl-ammonium salts. Phosphates such as ammonium phosphate are also used.  These salts also act as corrosion inhibitors. Water-soluble acids such as sulphuric, hydrochloric or acetic may be added with the salts but the pH should be from 6 to about 9. Petroleum oils containing 12-20 per cent paraffins may be diluted with a ketone and treated at 40-75 DEG  C. with aqueous urea containing sodium nitrite.

Abstract: 524,039. Valve generating circuits. TELEFUNKEN GES FUR DRAHTLOSE TELEGRAPHIE. Jan. 20, 1939, No. 2001. Convention date, Jan. 20, 1938. [Class 40 (v)] A rectifier 11 is connected between grid and cathode of an over-coupled oscillator used to produce saw-tooth currents to relieve the gridcathode path of the valves of the heavy current which normally passes when the energy stored in the grid circuit is discharged. The scanning coils 9 can be connected across the grid coupling coil 6 as in Fig. 3 or across part only as in Fig. 7 ; and the grid of valve 4 can be connected to a tapping on the secondary if desired. Synchronizing pulses can be applied to the cathode of valve 4, as indicated in Fig. 7, or to the cathode of valve 11. In these embodiments only the current in the grid circuit has a sawtooth wave-form, and to provide such a Waveform in the anode circuit a tetrode or pentode is required as in Fig. 9. With this arrangement screen current stops when anode current ceases to flow and this, through the transformer 14, 15 and rectifier 16, charges a condenser 17. This condenser causes the potential on the control grid of valve 4 to vary and produces current of a saw-tooth wave-form in the anode circuit. Synchronizing pulses may be applied at 13C. Specifications 456,138, 456,640 and 456,666 are referred to.
