Patent GB-645755-A (GB)
Title: Production of nitriles
Filed: 1947-07-25
Abstract: Nitriles containing at least two carbon atoms are manufactured by reacting an olefinic hydrocarbon (preferably containing not more than eight carbon atoms) with ammonia, in gaseous phase, at temperatures between about 800 DEG  F. and the decomposition temperature of ammonia (preferably at 900-1025 DEG  F.), in the presence of a catalyst comprising a molybdenum oxide (e.g. the sesquioxide, dioxide, pentoxide or especially the trioxide), preferably on a support (e.g. silica gel, pumice, clays or especially alumina).  The molecular proportion of hydrocarbon in the reaction mixture may vary widely, e.g. from 2-98 per cent, preferably about 20-90 per cent.  If the catalyst becomes fouled it may be regenerated by careful oxidation (e.g. by passing a stream of air or air diluted with flue gases over it), preferably followed by a purging treatment (e.g. by passing nitrogen or carbon dioxide).  The pressure at which the reaction is effected may be subatmospheric, atmospheric or superatmospheric.  Examples describe the preparation of acetonitrile and a trace of propionitrile from propylene, of acetonitrile from ethylene and of acetonitrile, propionitrile and butyronitrile from butadiene. Other starting materials specified are butenes, octenes, pentadienes, ethylbutenes, hexadienes, heptenes, pentenes and styrene, and hydrocarbon mixtures containing one or more olefines. The Specification as open to inspection under Sect. 91 comprises also the use of catalysts containing a tungsten oxide and the use of a stream of hydrocarbon gases in the purging treatment following the regeneration of the catalyst.  An additional example of the production of acetonitrile from butadiene is given, and it is stated that olefines containing at least six carbon atoms yield aromatic as well as aliphatic nitriles.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in sheet conveying devices for paper sheet handling machinery
Inventor: FRY STANLEY REGINALD
IPC: B65H45/18
Filed: 1954-07-12
Abstract: 774,410. Feeding sheets; folding paper. CAMCO (MACHINERY), Ltd. July 12, 1955 [July 12, 1954], No. 20379/54. Class 100(1) In a sheet-conveying arrangement for a paper-sheet handling machine having an upper sheet-conveyer which overlies a lower conveyer comprising a plurality of freely rotatable balls which co-operate with a driving element such as a rotating roller or moving web to feed the sheets, the balls are carried in an apertured plate mounted upon suitable slide or equivalent support means whereby the apertured plate with the balls can be displaced in its own plane from normal operative positive to a position where the balls are readily accessible; in the latter position the balls may be varied in number or position or weight according to the nature of the paper to be operated upon. As shown, the device is applied to a blade-folding machine for interfolding two signatures, one signature being fed by tapes 14, 15 over supporting plates 16, 17 shaped to form a throat 16a, 17a for the blade 12. The other signature is fed at right-angles to the first signature by tapes 22, passes over supporting plates 19, 20 with.a throat 19a, 20a, and over a driven roller 24 against which it is pressed by the balls 23 freely mounted in apertures 32 in a plate 31. The devices 23, 24 feed the signatures up to a adjustable stop 26, and the number and weight of the balls used is such that the signature is not buckled and therefore incorrectly registered. To each end of the plate 31 is attached a member 33 having an horizontal arm 35, the two arms being inter-connected by a plate 37. The arms 35 and plate 37 have elongated slots 38, 39'for the reception of screw-threaded reduced portions of pillars 41 fixed to the machine frame. If nuts 43 on the screwed part 10 are slackened, the frame 33, 37 can be shifted relatively to the plane 13 of folding so that the plate 31 and balls 23 are moved outwardly from their operative position beneath the tapes 14 and plate 16 to an accessible position where the balls can be manipulated as required. A plate 44 attached to the machine frame prevents the balls dropping out of the plate 31 during such movement. The stop 26 may be carried on members secured to the sliding frame 33, 37.

Title: Improvements in apparatus for delivering regular quantities of granular or pulverised material
IPC: G01G21/00
Filed: 1927-08-05
Abstract: 299,910. Davis, F. W. Aug. 5, 1927. Automatic-feed weighers.-In means for delivering granular or pulverized material, of the type comprising a rotating table with a scraper, or alternatively with a telescoping collar, for regulating the supply, the material is delivered from the table into a rotating drum acting as a scale pan the vertical movements of which control the rate of delivery of the material from the table. The material passes through a telescopic collar O onto a rotating table L from which it is deflected by a stationary scraper V onto a pocketed drum J. The drum J is carried by a scale beam P and is rotated continuously through a universal coupling. If the quantity of material flowing onto the rotating drum is too great or too small the scale beam falls or rises and rocks a bell crank lever A connected by a spring B to a double-acting pawl D pivoted at its centre upon a continuously-rocking plate Q. One end or the other of the pawl is thus turned by the bell-crank lever into engagement with a ra.tchet wheel F, and the rocking movement of the plate Q causes the pawl to impart to the ratchet wheel a rotary movement which is transmitted by chain and sprocket gearing to a vertical shaft Z. The upper end of the shaft Z is screw-threaded, and thereby raises or lowers the telescopic collar O so as to regulate the flow of material to the table and thence over the drum J. The flow may be regulated by actuating the scraper V instead of the collar O. Specification 182,046 is referred to.
