Title: Bag dispensing apparatus
IPC: B65B43/22
Filed: 1972-12-13
Abstract: 1403396 Bag dispensing apparatus ETABS J MERAT and J VAUDEZ 13 Dec 1972 [17 Dec 1971] 57525/72 Heading A4T [Also in Division B8] In a bag dispenser a pile 2 of bags rests on platform 3, the top bag being dispensed through opening 7 by a contacting roller 5, control means causing the roller to rotate through a predetermined angle and the platform to move towards the roller via screw 4 to maintain the pressure of the bags on the roller constant. The periphery of rollers 5 has pins 28 or an adhesive or frictional surface and a portion e.g., gap 27, having no traction on the bags and which will be adjacent the bags at the beginning and end of a cycle of preferably one rotation. A cycle is started by actuation of a control switch 30. A vibrating roller drive motor 8 mounted on shock-absorber lever unit 9, 10 starts, electromagnetic 20 swings finger 22 off the top of the bag pile, cam 19 rotates with the roller shaft to lower suction pad 13 on to the pile via arm 12, solenoid 17 via arm 16 raises diaphragm 15 to create suction in pad 13, cam 19 lifts the top bag and finger 22 returns between the lifted bag and the remaining pile. A roller shaft cam 25 then lowers the roller which feeds the top bag through opening 6, 7 after diaphragm 15 is lowered to remove suction and the roller stops rotating and is lifted by cam 25 when the bag is ready for removal at 2a. The dispensing shoot 6, 7 is preferably vertical but may be horizontal and may contain a switch 29 in series with the starting switch and responsive to the presence of a bag in the shoot to prevent the starting of a fresh cycle. Screw 4 may be driven from the roller shaft via interchangeable chain and gearing 31-33 or by a separate motor and raises the platform, guided at 34, the thickness of a bag during a cycle or may raise the platform until a given pressure on the roller against the weight of the motor 8 acts on a pressure sensor which declutches the drive to the screw 4. The platform drive nut for screw 4 is in two halves which may be separated by lever 41 enabling the platform to be freely moved for loading with fresh bags. The control may allow a series of bags to be dispensed.

Filed: 1971-12-15
Abstract: 1350429 Testing cans for leaks BORDEN Inc 15 Dec 1971 [23 Dec 1970] 58302/71 Heading G1S Cans 16, Fig. 5 are fed by a screw 67 to a star wheel 63 and the pockets 14 of a spider wheel 10 carrying a series of brackets 42 and spool valves 48 and rotating on a hollow shaft 12, Figs.1 and 2 supplying air to the valves 48 via an air tank 36 and air lines 40. The hub 11 of the spider wheel also mounts a ring 76 which rotates with it and supports a second series of spool valves 78 which control any leakage from the cans into the test pockets 14 and pass this leakage to a tester 94 which detects air pressure build up and activates a rejection mechanism (not shown) to discharge a leaking can when it reaches the star wheel 57. At the loading station 4, Fig.5, the can is closed by a rubber seal 18, Fig.1, operated by co-operative movement between a plunger 20 and a closure fitting 30, and air under pressure is injected into each can via a valve 48 and a pipe 46. If a can is present in a test pocket 14 then a respective valve 48 is moved to the open position, Fig.3 (not shown), but if a can is not present then a photo-electric detector 64, 66 operates and a pulse generator 68 and sensor 74 is actuated to energize a cylinder 58 and move bumper rollers 52, 54 in unison to slide the valve 48 to the closed position, Fig.4 (not shown). The pressurized cans are then rotated by the spider 10 around the arc X-Y, Fig.5, to position 75 where the spool valves 48 are moved to closed positions by a stationary bumper roll 77. In this position the air supply to the cans is cut off and the can vented to atmosphere. If a can has leaked air into its pocket 14 then this air is directed via port 95 and pipe 88 to the ring 76 rotating with the spider and mounting the second series of test valves 78. These valves are operated also by bumpers 116 mounted on a fixed support 106 and allow the air to pass to the tester 94. Grooves 120, Fig. 6 (not shown) in the valve ring vent the leak detector to atmosphere.

Abstract: 1302690 Preparing cia-1-propenyl phosphonic acid and intermediates therefor MERCK & CO Inc 21 Dec 1970 [29 Dec 1969] 60639/70 Heading C2P Propadienyl phosphonic dichloride (II) is obtained by reacting propargyl alcohol with an excess of PCl 3  in the absence of an acid acceptor at 60-110‹ C. to form 2-propynyl phosphorodichloridite (I) and heating the latter to rearrange it. A solvent may be present but if a large excess of phosphorus trichloride is used, e.g. by using 10 to 30 moles PCl 3 per mole of the propargyl alcohol, the excess PCl 3  serves as solvent. The process is preferably conducted in an inert atmosphere, e.g. of nitrogen and HCl gas formed in the first step may be removed by distillation as it is formed. The process may be carried out continuously rather than step-wise, this being suitably effected by adding the reactants, e.g. in a PCl 3  to propargyl alcohol molar ratio of 3 : 1 to 10 : 1 to an inert solvent such as benzene, toluene, xylene, or cyclohexane, e.g. at 85-110‹ C. In this case, the formation of the dichlorophosphite intermediate (I) and its rearrangement occur simultaneously and the propadienyl phosphonic dichloride product is continuously removed from the reaction mixture as it is formed. The dichloride product (II) may be hydrogenated, preferably catalytically, to form cis-1-propenyl phosphonic dichloride (III), the preferred catalyst being palladium or Raney nickel on a support such as active carbon, barium sulphate or calcium carbonate. The hydrogenation is generally stopped when one mole of hydrogen has been taken up per mole of the dichloride (II). The dichloride (III) may then be hydrolysed with water to form cis- 1 - propenyl phosphonic acid (IV). The dichloride (II) may alternatively be hydrolysed to form propadienyl phosphonic acid (V) and the latter then selectively reduced to form (IV). The latter (selective reduction) step is suitably effected in a basic aqueous solution when 1-propynyl phosphonic acid dibasic salt (e.g. the disodium salt) is first formed by isomerization of (V) in the presence of excess base and is catalytically hydrogenated then in the solution, after initial dilution with water, to form the corresponding salt of (IV) which is then converted to the free acid (IV) by ion exchange. The cis-1-propenyl phosphonic acid is useful in making (Œ) and (- )(cis-1,2-epoxy propyl) phosphonic acid and salts and esters thereof which have antibacterial activity.

An alkylate for use as a steam cylinder oil is prepared by reacting an aromatic compound with a boiling point of at least 210‹ C., such as phenanthrene, anthracene, naphthalene, and substituted naphthalenes, e.g. naphthols, in the presence of an alkylation catalyst, with an olefin or alkyl halide of at least 8 carbon atoms, in a molar excess of at least 2 : 1, separating the catalyst sludge, and thereafter removing the acid components from the reaction product and finally distilling to obtain a residue of viscosity E 50 =50 to 100. Mineral oil fractions rich in aromatics boiling above 210‹ C. such as kerosine, gas oil, and spindle oil may be used as such or extracted with, for example, liquid SO 2 , furfural, nitrobenzene or antimony trichloride, and the extracts used after solvent removal or the fractions may be concentrated in aromatics by percolation over silica gel or floridin. The aromatics may also be obtained by cracking gas or spindle oil or from coal tar. Olefins of straight or branched chain, e.g. C 8 -C 10  or C 14 -C 18  olefins, may be used. Friedel-Crafts' halides or sulphuric acid are suitable catalysts. With AlCl 3 , an amount of 0.5-10, preferably 4-6 per cent by weight is used.
