Title: Fastening device for releasably connecting a strap or webbing to an anchorage
IPC: B63B3/56
Filed: 1959-02-23
Abstract: 873,291. Stud and socket fastenings. AEROQUIP CORPORATION. Feb. 23, 1959 [June 6, 1958], No. 6209/59. Class 44. A fastening device for releasably connecting a strap or webbing to an anchorage comprises a T-shaped element 10 formed with a wide foreshortened body 16 and arm portions 13, 13<SP>1</SP> extending therefrom and having a slot 11 extending across the element for receiving the strap or webbing with the latter forming a bight around the body and an anchor member 15 having a slot 18 therein of width to pass the thickness of the element 10 when it has a strap or webbing 12 therearound and of length greater than the width of the body of the element but less than the width of the element across the arm portions, such that the element with the strap or webbing therearound can be passed through the slot 18 if the element is orientated so that the direction of width of the element across the arm portions is oblique to the direction of the length of the anchor member slot, but can thereafter be locked against withdrawal through the latter under tension on the strap or webbing by moving the element so that the direction of width of the element across the arm portions becomes parallel to the direction of length of the anchor member slot and the arm portions of the element engage the anchor member at each end of the slot in the latter. The anchor member may have lips along the sides of its slot 18 to restrict swinging movement of the element 10.

Abstract: 1491525 Buffer storage of articles during conveyance DE FORENEDE BRYGGERIER AS 13 Feb 1975 [13 Feb 1974] 6224/75 Heading B8A The speed of a buffer conveyer 4 is continuously adjusted to maintain a predetermined number of objects in a buffer section 4. The objects are discharged from a working station 1 by a conveyer 3 and are fed to a downstream working station 2 by a conveyer 7. Objects entering and leaving the buffer section are counted by devices 8, 9 and the difference is used by a recording means 12 to control the speed of the conveyer 4. When the objects are bottles, a normal accumulation as shown at 14, 6 is preferred and a minimum amount of noise is caused due to the bottles striking each other. With larger objects such as cases the buffer section is adapted for a single row of the objects.

Title: Process for the catalytic hydrogenation of carbon monoxide
IPC: C07C29/151
Filed: 1950-03-20
Abstract: In the catalytic hydrogenation of carbon monoxide, small amounts, preferably 0.5-5 per cent by volume, of ammonia or its derivatives gaseous under the reaction conditions are added to the feed gas. Liquid and gaseous hydrocarbons of high olefin content are produced in addition to nitrogen compounds, mainly primary amines.  The olefinic gases may be polymerized and blended with the primary liquid hydrocarbons.  Iron catalysts of high alkali content may be used, especially those which have been reduced at gas velocities of at least 1.5 m./sec., with feed gases containing 0.5-2 vols H2 per vol. CO, at ordinary or elevated pressures, e.g. 10-30 kg./cm2., and 200-1000 l./l. of catalyst/hr.  Catalyst temperature may rise slowly in the direction of gas flow, and tail gases may be recycled.  In examples, water gas containing 1-3 per cent ammonia is reacted at about 200-220 DEG  C. and up to 20 kg./cm2. with catalysts containing 100 parts Fe, 5 parts Cu, and alkali silicates, KH2PO4 or CaO and NaOH equivalent to a K2O content of up to 8 per cent.

[Also in Division H1] A web of material 1 is printed in a screenstencilling apparatus through the interaction of a doctor roller 2 on a screen 11 the roller being forced into contact with the screen by magnetic forces deriving from the repulsive effect of opposing like poles. In the embodiment of Fig. 1 poles at the ends of the roller 2 are opposed by similar poles at the lower ends of magnets 3 and 4. The roller is mounted on the magnets through guides and pins 6, 5 such that it may move in the direction of the repulsive forces. In a further embodiment the guides and pins are omitted, a plurality of alternate magnets 3 and 4 being arranged along the length of the roller each pole 7, Fig. 3, of each magnet 3 or 4 being shaped so as to partially enclose the circumferential peripheral surface of the roller. This roller incorporates an arrangement of annular poles of suitable polarity for repulsive reaction with the poles 7. Such an arrangement may be achieved by either embedding annular permanent magnets in the surface layer material of the roller or by using so-called magnetic rubber appropriately magnetized. In a further embodiment the magnets 3 and 4 are replaced by electromagnets.

Abstract: 122,569. Nerat, R. H. April 30, 1918. Bottles, non-refillable.-Relates to closures for non-refillable bottles of the kind described in Specification 101,706 in which a spiral discharge passage is provided between inner and outer casings, the conical lower end of the inner casing being adapted to co-act with a conical valve-seating mounted in the bottle neck. The closure consists of a cylindrical or tapering shell 2, Fig. 1, having at its lower end a contracted conical portion 3 forming a seat for a valve 4, the cylindrical portion of which is slidable within an inner guide or cylinder 6 supported within the shell 2 by one or more helical ribs 15. The guide 6 is preferably formed with an integral head 6<a> below which is a series of peripheral apertures 8. An outer star-shaped guard 11 is secured on the flange 10 at the upper end of the shell 2 by the crimped base 12 of the headpiece 13. When the bottle is inverted, the valve 4 leaves its seat and the liquid passes out through the passage-ways 7. One or more indented spurs 16 in the cylinder 6 limit the movement of the valve. On attempting to refill the bottle, liquid passes through the apertures 8 and forces the valve to its seat. In the modification shown in Fig. 3. the interned lower portion 2<@> of the shell 2 is provided with an upwardly-convergent part 3' forming a seat for the portion 4<1> of the valve 5<1>.

Title: The production of amides
Inventor: STEEL DEREK KENNETH VINCENT
IPC: B01D11/00
Filed: 1965-02-19
Abstract: N-Alkylamides or N,N-dialkylamides are obtained by contacting a primary or secondary alkylamine with an allyl or vinyl ester of a monocarboxylic acid.  The reaction is generally effected at a temperature of 15-100 DEG  C. under atmospheric or elevated pressures and it may be catalysed by small quantities of water or acidic or basic catalysts such as the strongly acidic or basic forms of ion exchange resins. The process may also be effected by introducing a volatile reactant as gas or vapour to a point between the top and bottom of a still column down which the less volatile reactant is flowed at least partly as reflux.  In specific examples the preparation of diemthyl-acetamide and di-n-propyl acetamide is described.
