Title: Spectroscopic device
IPC: G01J3/20
Filed: 1954-02-24
Abstract: 765.441. Spectroscopic apparatus. FASTIE, W. G., and SINTON, W. M. Feb. 24, 1954 [March 24, 1953], No. 5461/54., Class 97(1) In spectroscopic apparatus including a dispersing element. and reflecting means associated therewith so that incident radiation is subjected to two or more separate dispersions by the dispersing element, optical deflecting means are interposed in the radiation following are dispersion for so directing the radiation that the final spectrum does not overlap any other spectrum. As shown, a light beam g from a slit 12 is dispersed by a concave reflecting grating 14 into a beam h focused as a spectrum on a circle 18 passing through the grating 14. The beam h falls on a right-angled reflecting prism 28 and is returned to the grating 14 as a beam i displaced from the beam h. The beam i is itself dispersed by the grating to form a beam j which is reflected by a second right-angled prism 26 and by a rhombic prism 30 to be returned to the grating 14 as a beam k incident on the grating from below the plane of the circle. The dispersed beam l from the beam k therefore forms a spectrum 42 located above the plane of the circle 18 in which the other spectra are located thereby avoiding overlap. By providing a second prism 28, diplaced from the first a further dispersed different portion of the 'spectrum may be produced on the circle 18 on the opposite side of the slit 12 to that produced by. the beam j by providing further prisms 36 and 30, the latter being oppositely arranged to the first-mentioned prism 30, another spectrum may be framed below the circle 18 and -the spectrum 42. The prisms may be replaced by plane reflectors, the reflectors 20, Fig. 8, being so mounted that their relative angular position can be adjusted by rotating one mirror by a screw 106 rotating both mirrors about a horizontal axis by a screw 106', while the reflectors 38, Fig. 9, are. similarly adjusted by screws 106<SP>11</SP> and 106<SP>111</SP>. The invention may be applied to the system described in Specification 731,943 and shown in Fig. 13. Light from a curved entrance slit 88 is collinated by a portion 77 of a concave mirror 78 and directed to a plane reflecting grating 14<SP>1</SP>. The dispersed beam is focused by a portion 79 of the mirror 78 to form a spectrum. adjacent a mirror 80 which reflects it thereon mirror 84 back to the mirror 78. After again being dispersed by the element 14<SP>1</SP> the beam is directed by the mirror 80 on to parallel mirrors 87, 89 by which it is displaced from the other beams and reflected back to the mirror 78 by a mirror 90 finally forming a spectrum on the curved exit slit 86 which is displaced from the plane of the other spectra. Alternatively the mirrors 87 and 89 may be omitted and the mirror 80 replaced by two relatively inclined mirrors which prevent superposition of the spectra.

Title: Improvements in and relating to dry carroting fur
IPC: D01C3/00
Filed: 1943-04-07
Abstract: 573,180. Carrotting fur. TRIGGS, W. W. (No- Mercury Felt Corporation). April 7. 1943, No. 5561. [Class 76] A process for "dry-carrotting" fur on the pelt comprises mixing a highly active concentrated liquid carrotting solution with pieces of substantially non-absorbent attrition material, which carry the solution without 'absorption thereof, to the exclusion of free-flowing liquid, tumbling the mixture with the pelts, and then separating the attrition material. The process is carried out in a rotating wooden drum, which may be glass lined and have an interior baffle, for a period not exceeding about 60 minutes (e.g. 15-30 minutes), the attrition material being then separated using a rotating cage, wherein the pelts may be treated with moving heated air. The attrition material has a specific gravity preferably less than 2, and in the examples consists of powdered flint, shredded rubber, wooden chips coated with paraffin wax, or pieces of synthetic resin, e.g., polystyrene. Pumice, carborundum, comminuted rubber, hard paraffin wax, natural or synthetic resins, e.g., Lucite, bituminous material, and asphalt (which may or not be hardened with sulphur) are also referred to. Carrotting reagents used in the examples are concentrated sulphuric and nitric acids, chloric acid, used either singly or in combination, to which may be added hydrogen peroxide and potassium permanganate as oxidising agents. Sulphamic acid, as a carrotting agent, and potassium or ammonium persulphate as an oxidiser, are also mentioned. A catalyst consisting of small quantities of zinc sulphate and chromium potassium alum may be used, the latter having a slight tanning action. The acidity of the carrotting solution may be reduced by adding an alkali such as ammonium or sodium carbonate or caustic soda to the contents of the tumbling drum. In the carrotting process it is preferable to protect the flesh side of the skin by coating with e.g., nitrocellulose lacquer, by securing two skins together, or by folding each skin.

Title: Manufacture of magnesium alloy extrusions
IPC: C22C1/04
Filed: 1954-02-25
Abstract: A method of making extrusions with blister free surfaces from magnesium-base alloys in atomized powder form, which powder contains non-metallic friable particles as contaminants, comprises subjecting the atomized powder to a differential comminution to crush the non-metallic contaminants and disseminate them uniformly throughout the powder without substantially reducing the size of the alloy particles, heating the powder and extruding it through a die.  The alloys are first atomized by causing a cool gas, such as a hydrocarbon gas or a mixture of hydrocarbon gas and hydrogen, issuing from a jet to impinge against a thin stream of molten alloy and the resulting powder is then screened to remove particles above 20 mesh and below 200 mesh sizes.  The comminution takes place in a ball mill, hammer mill or impact mill which exerts forces strong enough to crush the contaminants but not the alloy particles.  The powder is heated in the container of the extrusion press to about 550-850 DEG F.  Examples are given of an alloy having a composition of 3 per cent aluminium, 1 per cent zinc, 0,3 per cent manganese and the balance magnesium which is heated to 650 DEG F. and extruded to form a rectangular strip 1/8 inch by 7/8 inch at 5 feet per minute and also of an alloy having a composition of 1 per cent aluminium, 1 per cent zinc, 1 per cent manganese and the balance magnesium.

Abstract: 914,871. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 15, 1961 [Feb. 15, 1960], No. 5712/61. Class 40 (4). In an arrangement wherein identifying apparatus is taken into use each time a subscriber's meter registers a predetermined number of units to forward information for the printing of a ticket, the meter is isolated from control by metering impulses during this operation either by holding the meter magnet energized or by disconnecting it from the metering wire. The meter may be stepped on either the forward stroke (SM1) or the backward stroke (SM2) of the magnet armature, and contact k1, k2 is closed in a particular position of the ratchet-wheel, e.g. once per revolution, either when the armature is attracted or independently thereof. When the meter SM1 closes its contact k1, if the identifier SMD is idle group relay S1 energizes in series with the magnet and connects up already busy relay R6. If the identifier is already busy, the magnet holds over resistance r3 until R6 falls back. Relay S1 also connects up a corresponding relay T1 which operates the appropriate units relay U1. R2 energizes followed by R5 over wire t1 if the reading device is idle, and the identity of the meter SM1 is transferred by the marking of one wire in each of two sets K1, K2. The relay sets S1 . . . Sn, U1 . . . Um are arranged so that only one relay in each set can be operative at a time. The reading device controls a ticket printer which is not necessarily at the same exchange. Upon release of the reading device, R4 energizes over wire t2 followed by R3, thus connecting negative battery to SM1 in order either to release it or to energize it in the reverse direction and advance one step, contact k1 being opened in either case. The release of R5 restores the identifier. The meter SM2 is such that it does not hold in series with the marking relays, but is energized by negative battery and steps on to restore contact k2.

The output of a gas-making plant, e.g. for town or synthesis gas, in which a hydrocarbon is catalytically reacted with steam, is increased by gasifying methanol in part or complete substitution for, or in addition to, the normal feedstock, over one or more of the catalysts installed for normal operation of the plant. The methanol is preferably used simultaneously with one or both of a normally liquid hydrocarbon (A) and a normally gaseous hydrocarbon (B) having a higher hydrogen to carbon atomic ratio than A, e.g. B may be methane or natural gas, or a refinery gas, and the gas-making reaction may be performed in an externally heated tube reformer, or by a cyclic process, or by a partial combustion process. Multi-stage processes may be employed, e.g. the methanol may be fed to the hot gas produced by catalytically reacting A with steam, for reacting the mixture over a second catalyst, and in a modified form of the invention, the methanol is gasified in a vessel which succeeds the gasmaking stage, e.g. in a carbon monoxideconversion stage. This may be multi-stage, with the methanol injected before and/or between the stages, and a methanol synthesis catalyst may precede the operative conversion catalyst to reduce methane formation. Means for controlling the proportions of steam, feedstock and methanol delivered to the reaction zone are provided. An independent boiler may be provided to make up deficiencies in the usual waste heat boiler due to lowering of the temperature of the product gas caused by the methanol decomposition.
