Title: Process for the production of a fast adhering metal coating on insulating sheets, especially for the preparation of electric condensers
IPC: H01G13/06
Filed: 1926-11-11
Abstract: 261,392. Dubilier Conde,nser Co. (1925), Ltd., (Assignees of Pfiffner, E.). Nov. 12, 1925, [Convention date]. Condensers.-In a process for coating cellulose ethers and esters, for example acetyl cellulose, especially for the construction of electric condensers, the coating is made to adhere fast to the base by colloidally depositing an intermediate layer of metal or metallic oxide (which layer can be shown by a discolouration of bright yellow or brown to black, according to the thickness of the deposit) before depositing the metal coating by known methods. For close adherence of the metal coating, superficial saponification of the cellulose by alkalis or acids is necesary, a metal salt being added to effect a gentle action on the cellulose.

Title: Vehicle suspension level-regulating system
IPC: B60G17/00
Filed: 1970-06-12
Abstract: 1,260,781. Adjusting suspension height. FICHTEL & SACHS A.G. 12 June, 1970 [18 June, 1969], No. 28521/70. Heading B7D. A valve 6 in a conduit 5 connecting a levelling valve 4 to pneumatic or hydropneumatic suspension units 7 is opened to allow free communication between the levelling valve and the units 7 only when pressure rises in a brake conduit 9 due to application of brakes 11 by -actuating a master cylinder 8. The valve 6 includes a sliding element 102 which is displaced against spring loading 105 to align a transverse bore 103 with a passage 101 in the line 5 when a space 110 above a flexible diaphragm 107 is pressurized to a predetermined extent from the brake conduit 9 through a conduit 10. A non-return valve 114 having a throttle passage 115 allows rapid opening of the valve 6 when the brakes are applied so that the levelling valve 4 is effective to counteract brake dive, and delays closure of  the valve 6 when the brakes are released so that the pressure in the suspension units 7 is restored to normal. The valve 6 may permit heavily throttled communication between the levelling valve 4 and the suspension units 7 when the brakes are not applied to allow the suspension height to be adjusted when the vehicle load varies without applying the brakes.

Title: Improvements in or relating to electromagnetic devices for producing mechanical displacements
Inventor: OSBORNE CHARLES FREDERICK
IPC: H02K16/00
Filed: 1957-09-11
Abstract: 853,388. Electromagnets. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 9, 1958 [Sept. 11, 1957], No. 28638/57. Class 35. An electromagnetic device for producing a series of displacements of a member comprises a magnet pole 1 with the core 2 defining an annular air gap in which are located two solenoids 4 and 8 so that upon excitation of either of them they will be separately displaced axially. Each solenoid is carried by a disc 13 and 7, respectively, the disc 13 being integral with a centrally-disposed rod 14 constituting a connecting- member to transfer disc movement to a set of links connected to a driven member. A stop 5 rigidly connected to the core 2 constitutes an outer limit stop for the disc 7, the core face being the inner limit. Disc 7 is attached by a rod 11 and shaft 9 to two further stops 10 and 12 which thus move with disc 7 and constitute inner and outer limit stops for disc 13. By selective energization of the coils 4 and 8, therefore, two inner positions and two outer positions are obtainable for the disc 13 and hence the connecting-member 14. By making the distances between stops 10 and 12 four times that between 2 and 5 these positions correspond to 0, 1, 4 and 5. A second magnetic drive is provided either by a similar arrangement of coils and stops at the other end of the cylindrical magnet, or by a second magnet, in this instance both magnets being of " pot " type. The two drives are linked by an assembly of links to the driven member in such a way that equal movements of their connecting-rods 14 will produce movements of the driven member in the ratio 2 to 1 so that this in combination with the foul positions available on each drive provides for fifteen positions of the driven member in a series of equal steps. Three alternative link arrangements are described. The simplest form, Fig. 3, comprises two separate electromagnets A and B, the connecting members of which, 14 and 15, are joined by a horizontal link 23 to which they are connected by slotted hinges. Link 23 is pivotally connected at 26, one-third of the way along its length, to a member 25 constrained to move vertically. Thus equal vertical displacements of members 14 and 15 will result in corresponding vertical displacements of member 25 in the ratio of 1 to 2, respectively. Fig. 2 (and Fig. 4, not shown) show alternative arrangements for obtaining the same result with a single electromagnet with the solenoid drive at each end, the movement of member 14 being, in each case, translated into an equal and opposite movement of a parallel member 20 by means of the centrally-pivoted cross-link 17 ; members 23 and 25 forming the same function as in Fig. 3.

Title: Improvements in or relating to the production of artificial silk, filaments, threads, bands, ribbons and the like
IPC: D01F2/28
Filed: 1925-11-17
Abstract: Artificial silk, horsehair bands, ribbons &c. are prepared from solutions of acetone-soluble cellulose acetates which have been prepared in the cold by means of a solvent mixture of methylene chloride and an alcohol or other addition.  The alcohol &c. must be used in such limited amount as not to impart inflammable properties to the solution; the limit in the case of alcohol is a proportion corresponding to 30 per cent of the solution, and in the case of acetone, 20 per cent.  By the use of methylene chloride very highly concentrated solutions can be obtained, such solutions permitting a very high speed of spinning and a very short spinning distance; and the spinning can be carried out either by the evaporative method or by a wet process using a bath of high boiling point solvent from which the methylene chloride can be recovered by distillation.  The spinning conditions can be varied within wide limits by the addition of larger or smaller quantities of solvents such as dichlorethylene; and the speed of evaporation of methylene chloride is such that there may be spun either fine silk-like filaments or thick filaments resembling horsehair, or even thin tubes &c.  To the spinning-solutions there may be added softening-agents, colouring matters, and filling-materials especially bronze powder or dyes insoluble in water.  Methylene chloride by itself has no solvent action in the cold for either class of cellulose acetate; but by the addition of a small quantity of alcohol or its homologues, perfect solution is obtained without the application of heat; even an addition of 10 per cent of alcohol will enable this effect to be obtained, although it is preferred to employ about 25 per cent of alcohol. Alcohol or its homologues may be replaced by other solvents or by mixtures of solvents and non-solvents or by mixtures of non-solvents.  In examples, acetone-soluble cellulose acetate is dissolved in the cold in a mixture of methylene chloride and alcohol, and in a mixture of methylene chloride, benzene and alcohol.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of methyl alcohol, ethyl formate, and a mixture of ethyl acetate and alcohol, as additions to the methylene chloride; to the preparation of solutions of mixtures of acetone-soluble and chloroform-soluble cellulose acetates; to the use of methylene chloride as a diluent for solutions of cellulose acetate for the purpose of homogenizing the solutions and for decreasing their inflammability; and it includes examples of the preparation of solutions with the aid of mixtures of triacetin, methylene, acetone and methyl alcohol, and also a modified process in which the cellulose acetate solutions are applied as a coating to nitrocellulose silk, threads, ribbons, &c. for the purpose of rendering these articles non-inflammable.  This subject-matter does not appear in the Specification as accepted.
