Patent GB-869625-A (GB)
Title: Diphosphoimidazoles
IPC: C07F9/6506
Filed: 1957-06-14
Abstract: The invention comprises alkali metal and alkaline earth metal salts of a diphosphoimidazole wherein the anion has the formula: <FORM:0869625/IV (b)/1> wherein R1, R2 and R3 are hydrogen atoms or lower alkyl groups of not more than 6 carbon atoms, or R3 and one of R1 and R2 are hydrogen atoms and the other R1 or R2 is the group -CH2CH2NH2 as in histamine or the group -CH2CH(NH2)COOH as in histidine.  The salts may be obtained by reacting the corresponding imidazole with amidophosphoric acid in aqueous solution under neutral or alkaline conditions and then adding a water soluble alkali metal or alkaline earth metal salt of a strong acid to form the desired metal salt.  An example is given for the production of the calcium salt of diphosphoimidazole. The products are useful for the phosphorylation of organic primary or secondary amino compounds the phosphorylation being effected by reacting such compounds with the alkali metal or alkaline earth metal salt in an aqueous medium at alkaline pH and at a temperature below 100 DEG C., preferably at room temperature.  It is preferred to use an alkali metal salt, e.g. sodium salt, for the phosphorylation.  An example is given for the phosphorylation of ethanolamine, alpha-alanine, beta-alanine and serine.  Other specified compounds which may be phosphorylated are glucosamine, tyrosine, tryptophan, histidine, proline, creatine, p-amino-benzoic acid, sulphanilic acid, peptides and proteins.

Abstract: 1393499 Air bed conveyers H E GLADISH 19 April 1973 [20 April 1972] 18898/73 Heading B8A Objects having a curved surface are conveyed by a support fluid film wedge which is produced by fluid from a plenum chamber adjacent curved support means escaping through directed nozzles communicating between the plenum and a surface portion of the support means. In the figure, an object 34, e.g. a toilet roll, is conveyed in a longitudinal direction and rotated about its own axis as indicated by the arrow, by means of air directed through nozzles 26, 28 formed in the inner surface of trough-shaped support means. A plenum chamber is formed below the trough by for example welding on a pipe section having a radius different from that of the trough. The trough also has a radius slightly larger than that of the article to be conveyed in order that atmospheric air may be drawn in by the operation of the nozzles 26, 28 to impart a rotating motion to conveyed objects. The conveyer may be used in dynamic storage systems (Figs. 4, 5, 6, 11, 16, not shown), in pressure loading a wrapping machine (Fig. 10, not shown), to convey pallets (Fig. 13, not shown), or to support and rotate rollers in a roller conveyer (Figs. 14 ,15, not shown).

In operation, when the non-contact-making end 46 of the blade is moved by an actuator 40 the strip portions 42 first move over dead-centre at the pivot point 51 whereby the arm 43 snaps over in slot 47 of the actuator 40 to move the strip portions 42 over dead-centre at the second pivot point 52 whereby the arm 44 and contact 45 instantaneously snap between the fixed contacts 53, 54 in a second snap-action. The arrangement is such that contact pressure is maintained until the first snap-action takes place whereupon the second snap-action takes place substantially instantaneously as the contact pressure falls off. The inwardly extending arms 43, 44 may be stiffened by longitudinally extending edge flanges 49, 50.

Title: Improvements in or relating to separation of carbon dioxide from ammonia
IPC: C01B32/50
Filed: 1953-07-09
Abstract: In a process for the separation of carbon dioxide from gaseous mixtures comprising carbon dioxide and ammonia by scrubbing <PICT:0745406/III/1> the mixture with a cooled aqueous solution of a weak base capable of reversible combination with carbon dioxide, e.g. monoethanolamine so as to absorb both the carbon dioxide and ammonia, subjecting the enriched solvent to a limited heating to expel the ammonia, subjecting the solvent to a further heating at a higher temperature so as to expel most of the carbon dioxide, and finally returning the solvent to the scrubbing step, the expelled ammonia is recovered after reacyling to the scrubbing step.  The recycled solvent may be maintained in a purified condition by continuously bleeding off a portion, distilling in the presence of alkali and returning to the cycle.  The solvent may contain a decomposition inhibitor, e.g. copper iodide or a vanadium compound.  As shown a gaseous mixture comprising carbon dioxide and ammonia is introduced via an upflow line 5 into a system comprising an absorber 1, stripping column 2, and heater 3, the absorber and stripping column being connected by downflow line 4 for the absorbing liquid and upflow line 5 for the evolved ammonia gas.  The solution in the absorber is thus continually saturated with ammonia, the excess being passed through an alkali scrubber 7 to produce ammonia free from carbon dioxide at 12a. The car bon dioxide which is substantially completely absorbed is recovered at 25 by passing the solution from stripping column 2 viat heat exchanger 16 into a system comprising regenerating tower 18, heater 19 and solvent condenser 22.  The regenerated solvent is returned via heat exchanger 16 to absorber 1.

Abstract: 883,141. Finishing yarns. SCRAGG & SONS Ltd., ERNEST. June 8, 1960 [June 4, 1959], No. 19104/59. Drawings to Specification. Class 120(3) In an edge-crimping process, unheated yarn is passed between an unheated blade and a support surface in resilient contact therewith and is subsequently heated, as by passage through an electrically- or steam-heated tube, to a temperature not higher than 20‹C. below the melting point of the yarn under low tension or relaxed condition to develop and set the crimp therein. The yarn may follow an angular path with the blade edge as the apex thereof and may be tensioned during its passage across the edge. The support surface may be constituted by a roller rotating in synchronism with the running yarn and/or of rigid construction with a covering layer of resilient, e.g. polyurethane plastic, material or composed of such material. The roller or the blade is resiliently mounted and the blade may engage the roller surface at an angle to a diametral line through the point of engagement so as to extend in the direction of movement of the running yarn. The relaxed condition may be achieved by "overfeeding" the yarn into the heating zone.

Title: Improvements in or relating to remote control systems
IPC: H02J13/00
Filed: 1928-07-06
Abstract: 295,017. Associated Telephone & Telegraph Co., (Assignees of Nelson, M. L.). Aug. 6, 1927, [Convention date]. Switching systems.-Switches or other apparatus located at comparatively short distances from a control station are operated and supervized over separate pairs of conductors of which one of each pair may be common to all. Direct current is sent in either of two directions to close and open a switch and alternating current is applied to the conductors by the closed switch to operate a supervisory signal. A change in the position of a switch which is not caused by the operator operates an alarm and a visual signal which identifies the switch; the visual signals may be lamps or relays. A key K is raised or lowered to send current in one or other direction from battery B through polarized relays 9, 24 in control and sub-station respectively, over line wires 22, 23, the latter wire being individual to the switch CB to be operated. A self-centering relay contact 25 is thus moved to actuate one or other relav 28, 29, thereby energizing closing or opening coil 32, 33 of the switch. Simultaneously contact 10 of relay 9 is set on contact 11 or 12. When the switch CB is closed an auxiliary contact 35 completes a circuit including an a.c. source such as 37 and a low impedance-relay 14 which operates a contact 15 to light one of the lamps 6, 7. The circuit of a relay 18 closes when the switch CB again changes its position, unless this is due to operation of the key K, owing to the operation of contacts 10 and 15. The relay 18 when energized lights a white lamp 8 and rings an alarm 21. Operation of the key K to reset the switch CB clears the alarm signal unless the switch fails to respond due to a fault. A similar system is also described in which relay indicators replace the lamps.
