Title: Improvements in or relating to apparatus for catalytic reactions
IPC: B01J8/06
Filed: 1938-08-10
Abstract: 517,744. Catalytic apparatus, processes, and agents. HERCULES POWDER CO. Aug. 10, 1938, No. 23633. Convention date, Aug. 30, 1937. [Class 1 (i)] Catalytic apparatus comprises a furnace of refractory material and a plurality of reaction tubes containing the catalyst. The tubes are supported above the roof of the furnace, and pass freely through the roof and floor of the furnace, means being provided to permit free expansion of the tubes. Firing means are provided at various elevations in the furnace wall, the gaseous combustion products being removed through a flue at the top of the furnace. The fluid to be treated is fed downwards through the tubes. The apparatus may be used for the treatment of a mixture of hydrocarbon gas and steam or other oxygencontaining compound, e.g., at 1600-2000‹F., to yield a mixture of hydrogen and carbon oxides. Suitable catalysts are oxides or metals of the iron group, mixed with alumina and if desired with lime, magnesia and silica; a mixture of alumina, nickel oxide and phosphoric acid may be used ; a catalyst comprising nickel oxides, magnesia and kaolin may be prepared in the form of a paste, subdivided, dried, and slowly heated to a temperature. 500‹F. above operating temperature, and the final roasting may be effected in the tubes ; or a catalyst may be prepared by heating nickel nitrate on diaspore to 500‹F. to decompose the nitrate, then reducing by means of hot combustion gases. The gas mixture produced may be used in the production of synthetic alcohol, or its hydrogen content may be increased by adding steam and passing over iron oxide or other catalyst to convert carbon monoxide to dioxide, the latter being scrubbed out. In the form shown, a fire-brick furnace 1 contains nickelchromium-iron alloy tubes 2 having flanges 5 resting on collars 6, and passing through tiles 3 at the top and bottom of the furnace. Removable plates G support the catalyst. The proportion of furnace wall surface to tube wall surface may be between 10 : 1 and 1 : 1. Gas burners 15 heat the furnace, the gases moving upwards with a circulatory motion to flue 18. The gases to be treated are fed in through valved pipe 11, and the products pass into headers 14 which are free to move with tubes 2.

Abstract: 301,135. Lumsden, G. H. C. Sept. 8, 1927. Stoppers with valves.-A closure for waterbottles, bags, and other receptacles formed with separate liquid inlet and air outlet passages, comprises an externally screw-threaded stopper adapted to engage an internally threaded ferrule, the screw-threaded portion of one or both of these members being interrupted circumferentially to form multiple longitudinally arranged water passages bounded by the stopper and ferrule and in free and open 'communication with the external atmosphere when the stopper is partly withdrawn. A threaded tubular extension of a cap-piece 9, Fig. 1, is formed with longitudinal slots 2 adapted to leave between them narrow strip-like portions which are strengthened internally by radial ribs 3, Fig. 2. The ribs are integral with the stripportions and with the wall of a central air outlet passage 6a which is open at its lower end and at its upper end communicates with the external atmosphere through lateral openings 7. A recess 8 beneath the cap-piece 9 accommodates a packing ring 8<a>. The ferrule is threaded for only a portion of its length to provide a face 5<a> against which a pin 10 or other projection on the tubular extension can engage to limit the outward movement of the stopper. In a modification the passages are formed by open longitudinal grooves and in some instances the lower portions of the intervening ribs are cut away to increase the area. of the liquid passage. In another form, the air passage is formed in a sector-shaped portion 1<a>, Fig. 9, in the stopper. The passages and ribs may be formed wholly in the ferrule, or partly in the ferrule and partly in the stopper. Specification 245,968 is referred to.

Title: Improvements relating to reversible disc ploughs
IPC: A01B15/16
Filed: 1954-08-16
Abstract: 763,033. Reversible disc ploughs. ETABLISSEMENTS A. BOURGUIGNON. Aug. 16, 1954 [Nov. 25, 1953], No. 23719/54. Class 6(1). A reversible disc plough wherein each disc carrier is pivoted about a vertical axis comprises for each disc a double scraper which is mounted on the disc carrier in such a manner that it may be tilted to bring one of its scraping edges in contact with the working face of the disc whenever the plough is reversed. The mounting of the scraper 12 on the disc carrier 1 comprises a spherical head 10 at the lower end of an adjustable and substantially vertical rod 8 which is held by means of nuts 9 in a horizontal lug 1. The head 10 is seated on a hole 11 in the lower arm of a U-shaped stirrup 11 which is integral with the scraper, the rod 8 passing through a slot 11b in the upper arm of the stirrup. This arrangement limits the movement of the head 10 in the stirrup, which in turn governs the axes of rotation associated with the scraper, the latter being such that the reaction of the soil upon the scraper maintains the scraper in contact with the disc 6 and causes it to be suitably readjusted when the disc's direction of rotation is reversed.

IPC: G06M1/10
Filed: 1959-07-14
Abstract: 921,711. Counting - apparatus. W. C. HERAEUS G.m.b.H. July 14, 1959 [July 14, 1958], No. 24213/59. Class 106 (1). In apparatus for counting bodies moving in a gas-tight system, the bodies are fed singly from a container 1 into a tube 2 in which they pass a testing device 4, for testing the density or radioactivity of the bodies before being discharged into a receiving container 3. Disposed on either side of the testing device 4 are coils 5, 6 surrounding the tube 2, the coils being connected to the arms of a bridge circuit 7 which is connected to a device comprising counting and other devices 9. On passing the first coil 5, the bodies cause a positive pulse in the devices 9, which include a counter, and on passing the coil 6, a negative pulse is produced. A check is thus obtained on whether all the bodies which have entered the testing device 4 have left it. The devices at 9 may include a time delay measuring device adapted to actuate an alarm if the interval between the pulses is greater than a certain predetermined amount. The bodies to be counted, which may be of radio-active material, contain sufficient electrically-conductive material to affect the inductance of the coils 5, 6. By employing devices counting the number of bodies entering and leaving a system, the number of bodies in the system may be checked.

Abstract: 1474370 Photo-electric detectors PLESSEY CO Ltd 17 May 1974 [22 May 1973] 24268/73 Heading G1A An arrangement for detecting various constituent modes of a transmitted light beam comprises: a central light detector and at least one annular light detector disposed coaxially with an axis intersecting the central detector; and electrical delay means associated with at least one of the light detectors. Portions of a light beam transmitted by an optical fibre 6, Fig. 1, undergo delays dependent upon the number of internal reflections within the fibre and characterized by the angles of emergence from the end 5. Thus the fast, direct mode emerges axially while the slow, indirect modes emerge at angles which increase with the delay. An array 1 comprising a central circular photo-cell 2 surrounded by coplanar concentric annular cells 3, 4 &c., detects the various modes. Distortion due to the delays may be minimized by compensating electrical delays 10, 11 between the photo-cell outputs. The arrangement may also be applied to e.g. a Fresnel lens by positioning it between the lens and its focal plane.

A scale for indicating the position of a movable object has recorded on it in one track 1, Fig. 4, sequences of cyclic code marks, and in an auxiliary track 3, a series of marks controlling the reading time of the code marks. The code marks are sensed at a single position by head 4, Fig. 6, and signals are entered into a 4-stage shiftregister 6 stepped at the centre-point of the marks by the transition from "1" to "0" or vice versa in the auxiliary track, sensed by head 7. The shift-register always contains a sequence of four code marks which indicates the position of the disc. The synchronizing pulses from the auxiliary track may be applied to step a shiftregister 11, Fig. 8, containing a pattern of bits corresponding to one of the code sequences. The outputs of the third and fourth stages are applied to a single-stage binary adder 12 and the output of this applied to the input. The result is that as the pattern steps through the register it remains identical to the pattern in shiftregister 6. A comparator 13 compares the contents of the two registers and gives an error signal if they differ.
