Title: Pyridine derivative and its preparation
IPC: C07D213/69
Filed: 1963-03-14
Abstract: 3,5 - Bis - (3 - phenoxy phenoxy) pyridine, a new compound, is stated to be a lubricant and heat exchange fluid.ALSO:The invention comprises 3,5-bis-(3-phenoxy-phenoxy)-pyridine and a method for the preparation thereof by reacting a 3,5-dihalopyridine (halo denoting chloro, bromo or iodo) with an alkali metal salt of 3-hydroxy diphenyl ether in the presence of copper or copper bronze at an elevated temperature.  The alkali metal salt of 3-hydroxydiphenylether may be prepared by reacting a 3-haloaniline with an alkali metal phenate in the presence of copper or copper bronze at an elevated temperature to produce 3-aminodiphenyl ether, diazotizing the latter compound and replacing the diazonium salt group by a hydroxide group by conventional means, and reacting the 3-hydroxy diphenyl ether with an alkali metal hydroxide. When the 3,5-dihalopyridine reactant is 3,5-dibromopyridine, it may be prepared by reacting pyridine hydrobromide with half the molecular proportion of bromine, in acetic acid, and heating the perbromide so formed until evolution of hydrogen bromide ceases.

Title: Improvements in or relating to the electrophoretic coating of metal articles
Inventor: SMITH MERVYN LESLIE
IPC: H01J9/08
Filed: 1952-04-23
Abstract: 716,583. Electrophoretic coating of metal articles. MULLARD RADIO VALVE CO., Ltd. Feb. 10, 1953, [April 23, 1952.] No. 10214/52. Class 41. A suspension of material employed in the electrophoretic coating of metal articles is treated with an ion exchange resin in order to improve its coating qualities. The invention is particularly applicable to suspensions of aluminium oxide, silicon dioxide, berylium oxide and their mixtures employed in coating the heaters of thermionic valves. In an example the suspension comprises 100 parts by weight of alumina in 300 parts by volume of butyl alcohol and 500 parts by volume of methyl alcohol (C.G.S. units). The suspension is shaken for half an hour with one part by weight of ion exchange resin "Zeocarb 225" (R.T.M.) which has been previously treated with hydrochloric acid. The suspension is decanted to separate it from the resin. An effect of the resin is to replace sodium ions present as impurity in the alumina by hydrogen ions. In another.example an alumina suspension for electrophoretic deposition which had deteriorated in use was shaken with "Amberlite I R 120(H)" (R.T.M.) and the resin then removed. The ion-exchange resin may, however, be left in the suspension in certain cases. A treated suspension may be dried and the solid material stored in readiness for re-suspension when required. Specifications 444,723, and 650,753 are referred to.

Title: Improvement in self-interrupting electromagnetic vibrator
IPC: H01H50/76
Filed: 1945-04-24
Abstract: 595,471. Electromagnetic interrupters. PLESSEY CO., Ltd. April 24, 1945, No. 10254. Convention date, May 26, 1944. [Class 38(v)] In an electromagnetic vibrator, t h e movable driver contact 36 is mounted on an auxiliary reed 37 which is separately formed and attached to one side of the main reed 26. In the form shown, the reed 26 carries an armature 39 which is adapted, when the coil 12 is energised, to engage the reed 37 at 40 after a predetermined time delay and move it to the left also, so that the normally closed contacts 36, 41 are opened and the coil deenergised. The reed 37 and contact carriers 31, 32 are attached to reed 26 by rivets 33 or by welding. Contacts 34, 35 on springs 31, 32 co-operate with relatively fixed contacts 24, 25 to interrupt and rectify the currents in the primary and secondary windings, respectively, of a transformer (not shown). In a modification, Figs. 4 and 5 (not shown), the auxiliary reed 36 is not engaged by the armature 39 and has a natural frequency slightly lower than that of the main reed so as to ensure correct sequential operation of the main and driver contacts. In a further modification, Figs. 6 and 7 (not shown), a stop extends along the auxiliary reed to cause positive actuation of the driver contact on deflection of the main reed in one direction, the auxiliary reed being free to return by itself.

Title: Improvement in textile fabric and method of making the same
IPC: D04H11/08
Filed: 1926-04-19
Abstract: 250,981. Duratex Corporation, (Assignees of Smith, P. S.). April 17, 1925, [Convention date]. Carpets, floor rugs, and mats; pile fabrics.-A pile fabric is formed by needling laps of fibrous material through and from both sides of a base fabric, preferably loosely woven from thread formed of two or more tightly-twisted strands, the lap of material on the second side being forced also through the lap of material on the first side of the base fabric in such amounts as to form a pile surface. Impregnating cement may be applied to the second side of the fabric. Two or more laps of fibrous material may be applied to either or both sides of the fabric. As shown, a lap of jute, wool or the like 22, Fig. 4. is first needled through the fabric base 10, and thoroughly felted. A lap of hair or the like 30 is then placed on the opposite side of the base and forced through the base and the lap 22. A cement 32, such as a solution of rubber or the like or a suspension of rubber composition in water, is then forced into the lap 30 and the base by impregnation mangling or the like. The fabric is then dried, calendered, and cured. The other side of the fabric is, then sheared or otherwise finished. The cemented backing serves to resist sliding when the fabric is used as a floor-covering. Fibres of different colours may be used in the two or more laps. It is stated that the tightly twisted threads of which the base fabric is composed deflect the needles of the needling machine so that the fibres of the laps are forced through the interstices only of the base fabric. Reference has been directed by the Comptroller to Specification 22728/91, [Class 42, Fabrics, Dressing &c.].

Patent GB-590881-A (GB)
Title: Method of and apparatus for manufacturing cast film
IPC: B29C48/08
Filed: 1945-04-25
Abstract: <PICT:0590881/IV/1> Polyvinyl resin films, sheetings, or the like are obtained by casting a solution of the resin upon a moving film-forming surface, removing the solidified film from the surface by longitudinal tension, and releasing the tension before the film is subjected to any subsequent step in this continuous process. The longitudinal tension may be applied by frictional engagement of the film with a pulling device such as a travelling band.  The apparatus may comprise an endless rotary casting belt, a spreader for depositing the polyvinyl resin solution on the belt in the form of a thin film, an ironer roll, means for driving the casting belt and ironer roll at the same speed, an endless auxiliary belt for stripping the cast film and transferring it to the ironer roll, speed-change mechanism for adjusting the speed of the stripping belt, a drying device comprising a series of rollers driven at speeds which permit free shrinkage of the film, and a collecting roll.  As shown in Fig. 1, a thin layer 6 of polyvinyl resin solution is deposited on the belt 4.  Solvent is evaporated as the film passes along the belt, and the solidified film is removed by the stripping device 8, from which it passes to ironer roll 9 and the drying chamber 2, and finally to the collecting roll 20.  The stripping device comprises an endless belt 21 which passes about the drive roll 22, stripper roll 23, and tension roll 24.  The belt is preferably so disposed in passing over the stripper roll 23 that its film-supporting surface has frictional engagement with the film which is still on the casting belt 4, although there may be a slight clearance, e.g. 1/16 to 1/4 inch.  The stripped film passes along the belt 21 beneath a bite roll 25 and a let-off roll 26.  It then passes to the ironer roll 9.  The belt 21 is driven by drive roll 22 which itself is driven by a motor through change-speed mechanism.  The film is forwarded by rolls 10 to the drying chamber in which it passes over rolls 11, 12, 14, 15, driven at speeds which allow the film to shrink.  The drive for each roller may be separately adjustable or the rollers may be divided into groups, those in each group being connected by an endless belt.
