Title: Improvements in electromagnetic switches
IPC: H01H50/54
Filed: 1957-05-13
Abstract: 836,571. Electromagnetic switches, contactmembers for switches. ARROW ELECTRIC SWITCHES Ltd. May 13, 1957 [June 14, 1956], No. 15076/57. Class 38 (5). An electromagnetic switch has bridging contacts 30 which may be readily changed from the normally open to the normally closed position or vice versa. A contact-carrying cage 40 has two springs 46, 461 which urge saddles 45, 45<SP>1</SP> inward against stops 41s, 42s, formed in the sides of the cage. The saddles 45, 45<SP>1</SP> have bent edges 47 which may be grasped by the fingers to insert the bridge 30 between one of the saddles and the stops. Each cage is bolted to an insulating bar 50 on a carriage 54a, 54b, 54c. The fixed contacts 12, 14 are carried in insulating members 16, 18 which are held by bolts 19 and the member 18 is removable with the fixed contacts 12 to allow access to the movable contact assembly for reversal of the bridge 30, from the Fig. 2 to the Fig. 3 position or vice versa. The carriage 54a ... 54c has a pivot pin 63 which can move in slots 66 in arms 68 of a support-plate 20 which also has loops 57 for adjustably anchoring the ends of tension-springs 55 having their other ends in apertures in the carriage so as to hold it against a strut 58 having knife-edge engagement with leg 54a of the carriage. The spring 55 also biases the carriage to the lower position when an armature 60 carried on the pin 63 is not attracted to the electromagnet 70. The latter is fixed to the plate 20 by screws 71, and when the screws are removed the armatures 60 and electromagnet 70 may be pivoted about the pin 63 to a position where the magnet 70 may be removed. A spring 80 carried on the end 54b of the carriage may be depressed as the carriage moves downward so as to engage a pin 82 and hold the carriage in a position where neither the normally open nor the normally closed contacts engage the fixed contacts so that the bridges 30 may be easily changed. The plate 20 complete with the electromagnet and contact structure may be removed from a base-plate 10 carrying a support insulator and fixed isolating contacts, as described in Specification 836,575. Specifications 836,572 and 836,574 also are referred to.

Title: Preparation of Organomagnesium Compounds
Inventor: RAMSDEN HUGH EDWIN
IPC: C07C51/15
Filed: 1967-04-03
Abstract: 1,160,310. Organo magnesium compounds. ESSO RESEARCH & ENG. CO. 3 April, 1967, No. 15208/67. Headings C2C and C2J. The invention comprises an adduct of magnesium with styrene, C 1  to C 7  alkyl, alkoxyl and aroxyl substituted styrenes and C 12  to C 40  condensed ring aromatic hydrocarbons, wherein magnesium is held in the said adduct in a ring structure. The ratio of styrenes to magnesium is 2:1 and the ratio of condensed ring aromatic hydrocarbons to magnesium is 1:1. The magnesium adds to the aromatic compound without displacing hydrogen. Examples of the organomagnesium compounds of this invention include styrene magnesium, anthracene magnesium, isoprene magnesium, chrysene magnesium, butadienestyrene magnesium, anthracenestyrene magnesium, isopreneanthracene magnesium, α-methylstyrene magnesium, pyrene magnesium. The organo-magnesium compounds are prepared by reacting magnesium metal with a compound of the above group or with styrene or a substituted styrene compound in admixture with a C 4  to C 40  conjugated diolefin, C 12  to C 40  condensed ring aromatic hydrocarbon, and mixtures of these, for a period sufficient to form an adduct of magnesium with the said compounds. The reaction is carried out in the presence of a high boiling mononuclear aromatic hydrocarbon, ethers, and paraffinic hydrocarbons, at a temperature of 20‹ to 170‹ C. for a period of 20 minutes to 48 hours, and the reaction is preferably initiated with a Grignard activator. The preferred medium is one comprising a C 4  to C 20  saturated cyclic ether such as tetrahydrofuran. Butadiene-styrene bis propanol as a benzene solution can be prepared by the following process. A mixture of one mole butadiene and one mole of styrene in tetrahydrofuran is added to one gram atom of magnesium turnings activated by ethylene dibromide in THF, and refluxed for 18 hours at 38‹ to 68‹ C. Two moles of propylene oxide in benzene is then added. Diphenyl adipic acid is prepared from styrenemagnesium by adding magnesium turnings to dibromoethane in THF, and then adding dropwise isoprene in THF. A solution of styrene in THF is added dropwise to the refluxing solution. After refluxing for 30 hours, the mixture is poured on to solid CO 2  suspended in THF and acidified, then extracted to yield a light yellow crystalline product. 2,5-Dimethyl-2,5-diphenyl- 1,6-hexane diol, and 1,4-diphenyl-1,4-butane diol are also prepared.

IPC: B01D1/00
Filed: 1953-06-03
Abstract: <PICT:0768995/III/1> <PICT:0768995/III/2> A high evaporation rate is maintained when evaporating non-flowing bodies of liquids such as ethyl alcohol, phthalate and sebacate esters, silicone oils, hydrocarbons, ketones, halogenated hydrocarbons and petroleum reactions which develop a "torpid" layer on extended heating, i.e. an invisible surface layer of liquid which impedes evaporation, by flowing off the torpid layer and removing it from the evaporating system.  In Fig. 1 the pot still 11 is supplied with liquid by a conduit 17 and a surface layer is continuously taken off by conduit 18, the liquid removed settling in tank 19 from which the upper liquid layer is removed at 21 and the lower returned to the still.

Abstract: 851,160. Locks of curled filaments: wadding. VERSIL Ltd. Dec. 18, 1958 [May 14, 1958], No. 15465/58. Classes 120(1), 120(3) and 142(4). [Also in Groups VIII and XIII] A web for thermal insulation is made by attenuating and grouping a number of continuously-extruded filaments to form a strand, drawing the strand over or through means to stress the individual filaments to varying extents to curl them and fuzz the strand, separating the fuzzy strand into short lengths and delivering them on to a conveyer to build up a web of high porosity. In Fig. 1, glass filaments 1 extruded from a furnace are collected by a hopper 3 and led into a V-groove in the periphery of a drum 5. The strand so formed is withdrawn by an air-traction device 6 into a tube 8 from which it is withdrawn by a further tractiondevice 9 over a device, e.g. a knife-edge 10 arranged to cause the strand to change direction sharply so that the filaments are curled to fuzz the strand, into a pipe 11. The pipe being constricted at 9, portions of the fuzzed strand are severed at intervals and expelled through an outlet 12a which may oscillate laterally to spread the ejected material over a conveyer belt of openmesh material on which it is compressed by an upper belt 16. The material is sprayed with binder at 18 and dried with hot air supplied through distributer heads 19. The speed and spacing of the belts may be regulated to vary respectively the density and thickness of the web, and one belt may serve a number of strandfuzzing and separating units.

Abstract: 154,254. Whitehead Torpedo Works, Ltd., and Sodeau, W. H. June 20, 1919. Generating by direct contact of combustion products; generating from water mixed with special gases or liquids.-Relates to torpedo-propelling means of the kind wherein the oxygen supply to the combustion chamber is augmented by injecting into the chamber, in addition to the usual compressed air, a strong aqueous solution of ammonium nitrate or similar salt. According to the invention, means are provided to delay the passage of the solution through the chamber, and to ensure complete decomposition of the ammonium nitrate. In the form shown in Fig. 1, the upper part of the combustion chamber 2 contains an annular chamber 7 into which the ammonium nitrate solution is fed by a pipe 9. The solution is sprayed through holes 10 against the walls of the chamber 2, and is exposed to the flame 12 from the fuel burner 6. Trays 13, 14, 15, which may be of various forms, delay the flow of the solution through the combustion chamber, or thesolution is caused to percolate through a lining of refractory material of a spongy or open texture. The combustion products pass to a second " decomposition " chamber B containing baffles, as shown, and thence by pipe 29 to the engine. Water or additional ammonium nitrate solution may be introduced into the delivery pipe, or into a chamber formed therein, by a jet 43. Anticorrosive substances such as oil, washing soda, and sulphites may be introduced at suitable stages. Before discharge into the combustion chamber, the solution may be pre-heated by the hot gases.
