Filed: 1971-11-22
Abstract: 1363749 Inductors A WALZ 22 Nov 1971 [24 Nov 1970 6 April 1971 6 July 1971] 54177/71 Heading HIT [Also in Division H2] In a device for feeding gas discharge lamps from A.C. mains, a voltage multiplying rectifier is enclosed in a cavity in an iron core of a choke. As shown, the choke has a winding 21 and a pair of cylindrical cores 22, 23 wound from iron tape. The magnetic circuit is closed by plates 25, 26. Plate 26 may be hinged and spring-biased so that each time the lamp is switched on, a switch (not shown) is operated so as to reverse the lamp connections and thus minimize cataphoresis. Fig. 1 (not shown) depicts a circuit diagram of the voltage multiplying rectifier which comprises a plurality of series diodes and shunt capacitors mounted on a printed circuit board to which the input and output leads may be sealed.

Abstract: 1,244,788. Coating apparatus. NORDSON CORP. 5 Nov., 1969 [15 Nov., 1968], No. 54245/69. Heading B2L. Apparatus for applying viscous material such as adhesive comprises a main body portion or service block A and a detachable gun C which has a passage 63 in communication with a passage 16 for the adhesive and a valve 50 which controls the flow of adhesive from the gun. The gun is mounted on a block B which is adjustably positioned on the main body portion A about the axis of passages 16 and 63. As shown adhesive can pass from a manifold 16 to a chamber 52 through passages 16 and 63 and the valve 50 is urged by a spring 51 into the closed position against a nozzle 48. Air under pressure passing through a manifold 18 and passages 32, 60 can act on a piston 59 to open the valve to release adhesive from the gun. The gun is held on to the block B by means of screws 41 and can be easily removed for replacement and cleaning. The block B is locked in position by a bolt 36 located in a slot 37 in the block which allows pivotal movement of the block to adjust the angular position of the gun. Heating elements are provided in a passageway 23 in block A under the control of a thermostat 22 to keep the adhesive in a molten condition.

[Also in Division F1] In a screw pump, e.g. for liquid manure, which in use is disposed in an upright manner to raise the manure from a pit or reservoir, the casing 10 has an upwardly extending delivery spout 26 and extends above outlet aperture 24 to form an accumulator chamber for collecting straw or hay carried by the manure. Alternatively, as shown, the chamber may contain a screw 28 of opposite hand to screw 12, to prevent straw or hay from collecting in the immediate vicinity of the outlet aperture. The casing may have a closable access opening therein for cleaning the chamber. A supporting frame 40 provided at the upper end of the casing has a cross-shaft 44 about which the pump can be pivoted to raise it from or lower it into the pit. Shaft 44 may be linked to the lifting hitch of a tractor or connected to the back of the manure tanker described in either of Specifications 1,084,249 and 1,170,797. The pump may discharge into the manure tanker via a flexible hose. Frame 40 may carry drive transmission means such as a gear-box, universal joints, belts and pulleys. Pump shaft 16 may be driven by an electric or petrol motor carried by the frame, or it may be driven by the power-take-off shaft of a tractor. The pump shaft is mounted in bearings 18, 20. Bearing 20 is lubricated via a pipe 38. A chopper blade assembly 32 may be supplied with water or other liquid via a pipe 36.

Abstract: 1308668 Treatment of materials with fluids HEBERLEIN & CO AG 20 Nov 1970 [24 Nov 1969] 55373/70 Heading D1L Thread- or web-like materials are treated with liquids, steam or gases on a beam which is rotatably mounted in a dwell tank. Prior to being wound on to the beam the material is passed through a liquid treatment bath where it is swollen or shrunk, according to need, to avoid stresses during treatment on the beam. Preferably the material is poured in a tortuous path through the pre-treatment liquid and wound on the beam below the surface of the liquid in the dwell tank. The preferred means of bringing the material on the beam into contact with the treatment medium is to force the fluid inside the beam through a hollow spigot and then out through perforations in the beam surface and through the material.

Title: A method of producing Ammonia Synthesis Gas
Inventor: KAPP ERNST
IPC: C01B3/02
Filed: 1967-12-06
Abstract: 1,188,395. Ammonia synthesis gas. METALLGESELLSCHAFT A.G. 6 Dec., 1967 [7 Dec., 1966], No. 55488/67. Heading C1A. Ammonia synthesis gas is prepared from a gas containing CO, CH 4  and H 2  mixed with a cooled flue or cracked gas which is rich in nitrogen, in proportions so that the converted gas will contain N 2  and H 2  in the correct ratio for ammonia synthesis. The mixture is cooled in a conventional regenerative system of cold storage masses to condense solid methane out. Oxygen is then removed from the methane-free gas by catalytic combustion with some of the hydrogen in the gas and then the gas is enriched with hydrogen by converting the CO with steam. The product is washed to remove CO 2  and hydrogenated to convert residual CO 2  and CO to methane. The synthesis gas may contain 1-1À3% of inert constituents. The gas containing CO, CH 4  and H 2  may be coke oven gas, refinery exhaust gas or a cracked gas. The gas rich in N 2  may be a gas cracked with air, e.g. coke oven gas, residual gas, or refinery exhaust gas and the cracking may be effected at a pressure great enough to allow the gas to be mixed with the gas mixture before cooling and some of the cracked or flue gas may be added to the gas mixture after cooling. The cracked gas or flue gas may be cooled and washed with water before being mixed with the coke oven gas.

Abstract: 1,174,738. Pipe couplings. VETCO OFFSHORE INDUSTRIES, Inc. 27 Nov., 1968 [6 March, 1968], No. 56330/68. Heading F2G. In a tool joint for pipes used in well drilling, a box section B has an internal circumferential groove 51 and a pin section P receivable in the box section has an external circumferential groove 41, and an expandible and contractible split latch ring 40 in one of the grooves is movable into the other of the grooves upon movement of the pin section into the box section. The ring has opposing ends at the split thereof provided with axially opening slots 62, 63 engageable by tool means for effecting movement of the ring out of the said other of the grooves upon relative circumferential movement of the ends of the ring. As shown, the ring has a bevelled upper edge 55 adapted to be engaged by the bevelled wall 56 of the box section whereby the ring is contracted as the pin section moves into the box section and subsequently expanded when the grooves 41 and 51 are coincident. To ensure proper initial assembly of the ring so that the slots 62, 63 register with a window 64 in the box member, buttons 67 and depressions are provided respectively on the box section and ring and to provide for correct angular orientation of the pin and box sections the latter have respectively a pin 69 and a pin-receiving slot 70. Contraction of the ring is accomplished by engaging the fingers of a tool in the slots 62, 63 and moving the fingers towards one another whereby the pin and box sections may be removed axially one from the other an inclined wall 91 merging into the groove 40 camming the fingers outwardly from the slots. The ring 40 is releasably locked in the expanded condition thereof by a locking device L comprising a screw-threaded body 100 provided with arms 101 connected thereto by reduced sections 102, the arms, prior to use, being inclined to the axis of the body and subsequently spread apart so that the extensions 105 engage inside the ends of the ring. Removal of the ring is effected by screwing a bolt 111 into the body to engage the wall 42 of the groove 40 to bend the arms back to the original positions thereof.
