Abstract: 107,674. Power, R. F. July 25, 1916. Steering and balancing. - In dualcontrol mechanism for aeroplanes, i n which the observer thrusts his operating-lever downwards into a socket in order to take over the control, means are provided whereby t h i s downward movement of his lever renders the pilot's control gear inoperative, and also whereby the pilot may resume the control at anv time. The pilot's control lever A is balljointed at A<2> to a portion sliding in the usual socket A', and the observer's lever B is arranged to slide in a similar socket B<1>, the sockets A', B<1> being pivoted at A<3>, B<2> to a longitudinal rotary shaft E and connected together by a rod C. A lever F, pivoted midway at F', passes through slots in the sockets A<1>, B<1> and engages under the levers A, B, so that, when the observer takes over the control by removing a pin F<2> and pushing his lever B into the socket B<1>, the pilot's lever A is raised until the ball joint becomes clear of the socket, thus preventing the pilot's body from fouling the control. The pilot's rudder bar G is mounted on a pivot G<1>, which is normally depressed through a fulcrum hole G<5>, as shown in Fig. 5, by a plunger H attached to the lever F, but is raised therefrom, as shown in Fig. 1, by a spring G<4> when the observer takes over the control, thus allowing the rudder bar G to slide freely when the observer actuates the rudder lever L by means of his pedals M, M<1> and wires L<2>, L<3>. The rudder bar G is connected by wires K, K<1>, levers K<2>, K<3>, and wires K<4>, K<5> to the lever L. The pilot may regain control by replacing his lever A in the socket A<1>, the rudder bar G being at the same time drawn back into position by a cable connected to the lever F and passing over pulleys C', E<3>, G<9>, or by a spring. The socket B<1> is made deep enough to allow the lever B to be partly inserted for dual control for instructional purposes.

Abstract: 1429855 Filter presses ISHIGAKI KIKO KK [trading as ISHIGAKI KIKO CO LTD] 6 March 1973 [6 March 1972 3 July 1972] 10873/73 Heading B1D In a filter press the filter cloths, the top and bottom ends of which are attached respectively to upper and lower bars which are connected to driving means via elongated flexible media (e.g. belts, chains, ropes), have cakes removed therefrom by moving them past scrapers or brushes positioned below the plates of the press. During at least a substantial part of the time cakes are being removed from the cloths the lower bars are raised and the upper bars are simultaneously lowered. After cake removal the cloths may be sprayed with water on their return travel. In the embodiment shown the filter press comprises plates 3 which are clamped and separated by a piston-cylinder mechanism (not shown). The filter cloths 11A, 11B are connected at their ends to bars 12, 13 and entrain rollers 14, 15 respectively. The bars are connected to chains 21 which entrain sprockets 20 which are driven through bevel gears 25, 26 from driven shaft 27. Each plate 3 comprises peripheral members 29 and 30, partition 31 and diaphragms 32 (e.g. of rubber, synthetic resin) provided with projections providing filtrate passages therebetween. In use with the plates clamped, slurry is introduced between each pair of adjacent cloths 11A, 11B by a slurry feeding device 39 comprising pivotable portions 39a, 39b attached to cloths 11A, 11B respectively, which device 39 receives the slurry via openings 38 in the plates and openings (41, not shown) in the cloths from pipes (36, not shown) connected to the plates. The filtrate passing through the cloths is discharged via the passages on the diaphragms 32. The filter cake is pressed further by forcing compressed water behind the diaphragms 32. This water is then discharged by compressed air and the plates are separated. The filter cloths are then moved past scrapers 47, 48 and the device 39, which is opened as it moves downwards with the cloths, 'and the cloths are sprayed with water from nozzles 49-51. In other embodiments, each cloth may be attached to a separate pair of bars 12, 13; the press may comprise alternate plates and frames; the plates may be separated individually; and the slurry feeding devices may take different forms. In another embodiment each cloth may be wholly positioned on one side of a plate and the scrapers may be spring loaded to allow them to be moved out of the way when the lower bars are moved around the rollers 14, 15.

Title: Improved method for rendering synthetic linear thermoplastic polymer products infusible
IPC: D06M13/188
Filed: 1955-04-15
Abstract: A method for rendering infusible threads, fibres, films, foils and like products made from linear thermoplastic polymers containing peptide (-CO.NH-) groups, comprises treating the products with a solution of a chromium compound, a solution of tannin, and a solution of tartar emetic (potassium antimonyl tartrate), in any order, and then washing and drying the treated products.  Suitable polymers are polyamides, particularly polyhexamethylene adipamide, polyurethanes, polyamide esters, and polymers of e -caprolactam.  Suitable chromium compounds are potassium dichromate, chromic sulphate, and chromium acetate. After the treatment with the chromium compound the products may be treated with a reducing agent, such as dilute sodium thiosulphate solution, to reduce any colouration produced.  The treating solutions are preferably acidified with formic acid, and each of the treating baths is desirably at a temperature of 60-100 DEG  C., preferably 90-95 DEG  C.  The baths may either be used to exhaustion or be continuously replenished, and the products may be dyed, if desired, either before or after the treatment.  The concentration of each bath is generally less than 5 per cent, both of the active solute and of the formic acid, if present.ALSO:In a method for rendering infusible threads, fibres, films, foils and like products made from linear thermoplastic polymers containing peptide (-CO.

Title: Thin film magneto-optical waveguide device
IPC: G02F1/313
Filed: 1976-03-18
Abstract: 1531883 Modulating light INTERNATIONAL BUSINESS MACHINES CORP 18 March 1976 [17 June 1975] 10962/76 Heading G2F A magneto-optical switching device for switching an optical beam in response to magnetic field variations and which relies upon selective mode conversion of the optical beam, comprises a thin  film optical waver guider 20 supported on a substrate, a light beam of, for example, TE mode, from a polarizer 10 being coupled into the waveguide by a coupler 21 and passing along a path 29 to a beam-splitter 24 whence it travels along paths 30 and 31 to respective output couplers 22, 23 and analyzers 27, 28 adapted to pass, for example, TM mode only. A direct current magnetic field H is established in the plane of the waveguide by means of a permanent magnet, field H being at an acute angle to both of paths 30, 31. A variable magnetic field H v1 , H v2  is also established perpendicular to field H. In addition, means are provided for periodically varying the magnetization along paths 30, 31, said means comprising, for example, a series of permalloy bars 25, 26 along each of said paths 31, 30, which bars, in a uni-directional magnetic field, provide for reversal of the magnetization along their respective optical path. This periodical variation in magnetization results in the mode conversion of an optical beam passing along the associated optical path. The said variable magnetic field is provided by a current-carrying coil and when the field H v1  is present, the resultant magnetic field will be directed longitudinally of path 31 and transversely of path 30. Thus, efficient mode conversion accurs in path 31 and is inhibited in path 30, an output therefore being provided by analyzer 27 only. If the current in the coil is reversed to provide a field H v2 , efficient mode conversion is provided in path 30 and is inhibited in path 31, an output therefore being provided by analyzer 28 only. Thus, the device is capable of demulti-plexing. Alternatively, since the device is symmetrical, it can also be employed as a multiplexer if analyzers 27, 28 are replaced by polarizers and polarizer 10 is replaced by an analyzer. The periodical variation in magnetization along paths 30, 31 may alternatively be provided by a periodic pattern of silicon islands, Fig. 4C (not shown), diffused into the magnetic waveguide material along each of said paths. The islands of silicon provide for periodical reductions of the magnetic field to zero. The magnetic thin film may be a substitute yttrium iron garnet, its substrate being a GGG wafer.
