Abstract: 373,565. Jib cranes. FAURE, A., Rue Verdier, and FAURE, A., 8, Rue de la Loire, both in Firminy, Loire, France. Dec. 31, 1931, No. 36093. Convention date, Feb. 28. [Class 78 (iv).] A set of parts for building up jib cranes of various forms comprises a winding gear, a carriage carrying a horizontal plate on a vertical pivot, a bracket with a horizontal spindle on said plate, a hollow post which can be mounted on said spindle, one or more hollow posts which can be fixed end to end to the first post, a truss having two sides of different length, either of which can be secured to said posts and which can be hinged at its ends direct upon said spindle, and a series of tie bars. As shown in Fig. 1, a duplex truss a, b is pivoted on a spindle e<1> carried by a bracket e attached to a plate f. This plate is mounted on a pivot g carried on a carriage l which may be fixed and tilted by screws n. Tie bars h connect the truss to a box i containing the winding gear. This box may be mounted on the ground, the winding rope passing thereto over pulleys placed at p, q, r, and along the axis of the pivot g, stability being maintained by a weight on the plate f. In Fig. 3, the truss is mounted on a truncated post 1 by bolts passing through holes 5 in the post and holes at the apices of the truss. The post consists of two flanged half-tubes, riveted together at intervals, and is mounted on a pin 3, which engages a gusset 2 riveted to the post. The duplex construction of the truss permits it to fit around the post. A pulley bracket 6 on the post has two spindle positions 6a, 6b, one in which the rope may be directed outside the post, as shown, and the other inside the post when the winding gear is placed on the ground and the rope passes thereto along the axis of the post and the pivot g. In Fig. 7, the truss is attached to a post 1<1> mounted on a similar post 1 pivoted on the bracket 4, the lower end of the post 1<1> being left unriveted to form a split socket which receives the upper end of the post 1, the posts being rigidly connected at 8, 81 by nuts and bolts. In each of the constructions, Figs. 3 and 7, the truss may be dispensed with, the post or posts being inclined so as to act as the jib. In a further modification, Fig. 9, the truss is attached to a rotatable tube 10 which surmounts the posts 1, 1<1>, and is supported by an arm 11 fixed into the wall of a building. The hoisting rope o passes along the axis of the posts and over pulleys t, u, to the winding gear i.
Patent GB-423629-A (GB)
Title: Improvements in and relating to kinematographic projection apparatus
IPC: G02B27/14
Filed: 1933-12-22
Abstract: 423,629. Colour kinematography. CALLIER, A., 38, Boulevard Albert, Ghent, and GILBERT, F. HEGER-, 82, Rue Joseph Bens, Brussels, both in Belgium. Dec. 22, 1933, No. 36123. Convention date, Dec. 24, 1932. [Class 97 (i)] Four images are projected through two pairs of complementary colour filters by means of prism systems which separate the image beams so as to enable normal lenses of relatively large aperture to be used. As shown in Fig. 1, two pairs of complementary colour records, side-by-side, and side uppermost on the film, are projected simultaneously by four prism systems and separated lenses 18 ... 21. Each prism system comprises a right-angle prism 16, a roof prism 15, and a right-angle prism 17, cemented together, and rotates the image beam through a right-angle about its axis. The members of the pairs of records may be erect, and arranged in series in a single rank on a film, and may be projected with the aid of two rhomboidal prisms which displace the two central image-beams in opposite lateral directions. The Specification, as open to inspection under Sect. 91, describes also the use of four rhomboidal prisms in the projection of pairs or erect images in two ranks on the film, the use of a pair of projection lenses of different focal length from the other pair, so that, when the pairs of images have been taken successively and are projected simultaneously, one pair of images may be projected out of focus, and an optical system for use in a camera. The camera system, Fig. 1 (Cancelled), comprises a prism 2, with a transmitting-reflecting surface 2<a> and a totally reflecting surface 2b, and lenses 5, 6, and colour filters 7, 8, to produce images on a film 9. The lenses 5, 6 are separately adjustable for focusing by means of tubes 12 having an external thread engaging a support 11, and an internal thread engaging the lens tube. To prevent variation in the relative sizes of the images produced by the two lenses, as the focus of the lenses is altered while the subject being photographed moves towards the camera, additional lens systems 10 are provided in front of the lenses 5, 6. Each system comprises a positive and a negative lens, and the positive lens 10<b> of one system and the negative lens 10<a> of the other system are connected, as shown, to the tubes 12, so that the separation of the lenses in each system 10 varies as the focus of the lenses 5, 6 is varied. The systems of lenses 10<a>, 10<b> may have no power when the lenses 5, 6 are focused for infinity, and the power of one may increase and of the other decrease, during adjustment of focus of the lenses 5, 6. Alternatively, the powers may both decrease, or may both increase, or one system may be dispensed with. This subject-matter does not appear in the Specification as accepted.

[Also in Division H1] Heart-cam and hammer zeroizing apparatus is modified by progressively increasing the pressure on the hammer until the numeral wheel is zeroized. A self-interrupting electromagnet 17 steps a ratchet wheel 6 so that a pin 7 presses against a leaf spring 11 to turn the hammer 4 about its pivot 12. The hammer engages the heart cam 2 lightly, but successive steps of the ratchet wheel 6 increase the pressure until the pin 7 falls off the end of spring 11. The circuit to the electromagnet 17 is broken when a cam 8 opens contacts 15. The self-interrupting circuit, Fig. 3, includes a pivoted steel arm 25 which is attracted by a permanent magnet 26 when the electromagnet energizes. The resulting break in circuit at 22, 23 releases the electromagnet but the arm 25 is restored only when acted on by the left arm of notch 31.

Title: Process for the production of ammonia synthesis feed gas
IPC: C01B3/36
Filed: 1961-10-11
Abstract: A mixture of hydrogen and oxygen, suitable for use as ammonia-synthesis feed-gas, is made by separately reaching a light hydrocarbon, i.e. C1 to C4, e.g. methane, ethane, propane, butane or mixture thereof, with steam, yielding carbon monoxide and hydrogen, and a hydrocarbon of higher molecular weight, i.e. C5 upwards, e.g. hexane, naphtha or crude oil, and air with or without steam, yielding carbon monoxide and hydrogen, mixing the two effluent streams, and purifying the mixed gas. The light hydrocarbon and steam react, in the presence of a reforming catalyst, e.g. iron oxide, aluminium oxide or nickel oxide, at a temperature of 1200-2000 DEG  F., the space velocity being 1000 to 2000 v/v/hr.  The hydrocarbon of high molecular weight and air with or without steam are preheated to 600-1500 DEG  F., and are reacted in a partial oxidation reactor, at a temperature above 2000 DEG  F., at a pressure of 50-350 p.s.i.g. The two effluent streams are mixed in the proportion of 1.5 to 3 volumes steam-reformer effluent per volume of the partial-oxidation effluent.  The mixed gases are then reacted with steam in a water-gas shift reactor, containing a catalyst, e.g. iron oxide promoted with oxides of chromium, potassium, manganese and aliminium, operating at a temperature of 700 DEG  to 800 DEG  F., and with space velocity between 100 and 500 v/v/hr. The gases are then scrubbed with water or basic aqueous solutions, for example monoethanolamine solution or cuprous ammonium acetate solution or both, and sodium hydroxide solution.  The water-gas shift reaction and scrubbing, which remove most of the water, carbon dioxide and carbon monoxide, may be repeated. The gases may now be passed through a methanizer, containing a catalyst, for example copper oxide or nickel or alumina, operating at 550-750 DEG  F. and 150-500 p.s.i.g. with space velocity of 1000 to 4000 v/v/hr; this process removes residual carbon monoxide.
