Title: Apparatus for depositing rows of cigarettes in receptacles
IPC: A24C5/354
Filed: 1931-06-26
Abstract: 378,606. Cigarette-making machines. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, ' Germany. June 26, 1931, No. 18554. Convention date, Nov. 8, 1930. [Class 130.] To deposit rows of cigarettes in receptacles, a holder is lowered intermittently a distance equal to the height of a layer of cigarettes and after a number of such movements the holder is lowered a greater distance to transfer layers of cigarettes to the next compartment in the holder, and when all the compartments are full the holder is lowered a greater distance to transfer the layers of cigarettes into the next holder. The cigarettes are thrust from a conveyer belt on to a plate in front of a holder until the foremost cigarette actuates an electric contact and a slide pushes the layer of cigarettes from the belt into the holder. As shown in the Figures, the cigarettes from a continuous rod machine are delivered on to belts 4, 5 and are passed by rotating brushes 10 on to plates 6, 7 until the foremost cigarettes engage stops 8, 9 which close an electric circuit and cause a shaft 23 to rotate. Cams 24 on the shaft 23 actuate, through rods 27, a shaped slide 11<1>, 11<11> to push the layers of cigarettes from the plates on to the holders S. One of the cams 24 also actuates a pawl 32 and a ratchet wheel 34 to rotate intermittently shafts 33 and move endless chains 14 on which the holders are carried. A cover-plate 35, Fig. 5, moved through cams 36 on the ratchet wheel determines the amount which the holders are lowered, the plate being arranged so as to prevent the pawl engaging the teeth of the ratchet wheel and producing the three different movements referred to. A projection 37 on the ratchet wheel 34, acting through levers 39, 40 forces the filled holders out of the machine.

Abstract: 770,869. Covering rods or tubes. MANNESMANN AKT.-GES. June 30, 1955 [July 5, 1954], No. 18936/55. Class 99(2) A method of applying insulation to the outside of a tube, rod or the like comprises continuously advancing the tube axially and feeding thereonto at the same speed a strip of insulating material of a width at least approximately equal to the peripheral dimensions of the tube after it has been preformed to a. U-shape to embrace part of the tube periphery and then passing the partially embraced tube through an insulation pressing pass operative to close the limbs of the U snugly against the remainder of the periphery of the tube. As shown an insulating strip 2 for example, a synthetic resin plastic strip is passed between shaping rollers 3a, 3b which impart a U-shape thereto. The strip is fed with the tube past a guide 5 and then between rollers 6 (see also Fig. 4). The strip is thus applied tightly around the tube. The encased tube then passes between a second pair of profiled rollers serving to smooth the insulation. The tube can be heated or have an adhesive layer applied thereto. The strip can be heated before being applied to the tube. The rollers 6 are slightly inclined relatively to one another. Instead of the two rollers 7 four rollers can be arranged around the tube or more than two roller pairs may be used, the pairs being arranged at equal angles to one another. The edges of the strip may overlap and a number of layers can be applied to the tube. Bituminous material can be used for the strip.

[Also in Division B3] A fluid-pressure cylinder comprises a body having a cylindrical bore 11, Fig. 1, in which a piston 27 is mounted for reciprocation and exposed circular reference end surfaces 33, 34 concentric with the bore 26 so that they may be used to locate the position of the axis of the bore with respect to a structure upon which the cylinder is to be mounted. The diameters of the surfaces 33, 34 are equal and less than that of the outer surface of the cylinder. The surfaces are received in recesses 15, 16 in cylinder heads 12, 13 with a close fit against the outer walls of the recesses. The piston rod 28 extends through a gland 30 in cylinder head 13 and, as shown in Fig. 2, is connected by a pin 42 to the movable jaw 38 of a clamping mechanism which is in slidable dovetail engagement with a guideway 39 of a work-table of a machine tool on which the cylinder is mounted by means of lugs 20 welded to the cylinder heads and bolted to the work-table. For aligning the cylinder axis with the centre point 44 formed by the intersection of the centre lines of the rod 28 and of the pin 42, the jaw 38 is first mounted on the guideway 39 and the distances " A " and " B " of the point 44 respectively from the dovetail edge 47 and the top surface 48 of the guideway are measured, for example by a Vernier caliper. The cylinder is then placed in its approximate position on the work-table and the reference surface 34, Fig. 4, is brought into contact with the caliper edge 53 which has been set from the edge 47 at distance " A " less one-half the diameter of surface 34. A like procedure is then followed for the surface 33 so that the axis of the cylinder bore becomes located at a distance " A " from the dovetail edge 47. Similarly the surfaces 33, 34 are used to locate the axis of the bore at distance " B " above the guideway top surface 48, shims 49 being added under the cylinder heads 12 and/or 13 if necessary. The cylinder is then bolted on the work-table. For aligning long stroke cylinders a collimator in conjection with V blocks may be supported on the surfaces 33, 34 and a reference point scribed on the machine upon which the cylinder is to be mounted.

Abstract: Ethylene oxide containing acetaldehyde as impurity is purified by continuously passing the ethylene oxide in admixture with an alkali metal glycolate dissolved in a quantity of a polyoxyalkylene glycol of molecular weight between 100 and 700 sufficient to render the reaction mixture homogeneous in the liquid phase but not in excess of 5 per cent by volume of the ethylene oxide (as liquid), through a reactor whose internal temperature is maintained between 0 DEG  and 180 DEG  C., under a pressure sufficient to maintain the reaction mixture in the liquid phase, the reaction conditions including concentration of glycolate and contact time being so chosen that not more than 5 per cent by weight of the ethylene oxide is reacted, and recovering purified ethylene oxide from the product.  In the preferred process, the alkali metal glycolate is the sodium, potassium or lithium glycolate of the glycol solvent, the glycol has a molecular weight of about 400, the temperature is between 30 DEG and 100 DEG  C., the pressure between 100 and 2000 lbs. per square inch, the alkali-metal concentration between 0.010 and 0.025 gm. atoms per litre of reaction mixture, the volume ratio of glycol to ethylene oxide from 1 to 20-100 and the contact time about 1 to 120 minutes, especially 20 or less minutes.  An acetaldehyde content of 0.67 per cent may thereby be reduced to 0.048 or less. Examples are given wherein, using illustrated apparatus (not shown), ethylene oxide and glycol solution containing sodium glycolate are separately pumped into a mixing device from which the mixture passes to a 72 ft. tubular reactor of 0.154 inch bore maintained at about 95-100 DEG  C. and provided at its exit with a pressure let-down valve allowing the desired pressure to be maintained in the reactor; the reaction product then passes to a still operated under normal pressure wherein purified ethylene oxide is distilled off and the residue passed to waste. Specification 736,991 is referred to.  According to the Provisional Specification, the purification is effected by means of any basic material dissolved in a sufficient quantity of organic hydroxy compound to render the reaction mixture homogeneous in the liquid phase and is restricted to use of a contact time of between 1 and 120 minutes.  Specified organic hydroxy compounds are methanol, ethanol, ethylene glycol, diethylene glycol, any polyoxyethylene glycol and a polyoxypropylene glycol.
