Title: Guiding-device for slide-rod
IPC: B64C9/24
Filed: 1945-06-08
Abstract: 593,303. Slide guides. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU NORD. June 8, 1945, No. 14568. Convention date, March 6, 1944. [Class 12 (i)] [Also in Group XXXIII] A guide for a sliding rod comprises at least three rollers located on opposite sides of the rod, some having a transversely displaceable axis and being resiliently pressed against the rod and there being not more than two rollers with fixed axes (if these are arranged at opposite sides of the rod), these rollers with fixed axes then being located in different planes transverse to the rod and the rod bearing thereagainst under the action of the resiliently pressed rollers. The rod is thus always held against the rollers and variations in size do not cause jamming. As shown in Figs. 1 and 4, a sliding rod 1 of straight or curved form is guided between two pairs of rollers of hyperbolic shape 2, 3 and 4, 5, one roller 2, 5 of each pair having its trunnions 6, 9 fixedly located, while the other roller 3, 4 of each pair has its trunnions 7, 8 guided in oval slots 18 and constrained by springs 19 whereby the rollers are urged against the rod. The hyperbolic form of the rollers automatically returns the rod if displaced laterally from the position shown in Fig. 4, while any anti-clockwise tilting of the rod from the position shown in Fig. 1 is returned by the action of the spring-urged rollers 3, 4. Collars 13, 14 in conjunction with the frame 10 define the end limits of the rectilinear movement. Leaf springs or a helical spring joining displaceable rollers on opposite sides of the rod may be used instead of the springs 19 joining the fixed and displaceable rollers of a pair. Fig. 8 shows a form with two rollers 23, 24 having fixed axis and one resiliently mounted roller 25. Fig. 9 shows the guide applied to the support rod 32 'of a front slot baffle 31 of an aircraft wing 30. The guide is also applicable to the support rod of a movable deflector plate of a movable rear flap, Fig. 11 (not shown).
Patent GB-812691-A (GB)
Title: Improvements in and relating to electric switchgear
Inventor: HEWITT JOHN
IPC: H01H33/30
Filed: 1955-05-20
Abstract: 812,691. High-tension switches. ENGLISH ELECTRIC CO. Ltd. May 16, 1956 [May 20, 1955], No. 14601/55. Class 38 (5). A circuit-breaker with a powerdriven operating mechanism has a control member to initiate operation of the mechanism in either direction and which is thereafter moved by the mechanism during operation. An airblast breaker has a compressed air chamber 10 and fixed and moving contacts 21, 22 in insulators 13, 14. The moving contacts 22 are coupled by links 25 to cranks 26 secured to a rotatable shaft 27 having a further crank 29 coupled by a link 30 to a piston-rod 31 which carries a piston 32 slidable in a cylinder 33. To open the breaker, a valve 54 is operated to admit air under pressure to the left-hand side of a piston 52 which starts to rotate the air-pressure inlet tube 17 so that a link 47 moves the top of a lever 45 to the right. The lower end of the lever 45 is coupled by members 48, 49, 50, 51 to one of the cranks 26 and the lever 45 pivots about its lower end, thus moving a link 44 to cause anticlockwise rotation of a plate 43 operating a valve 39. This opens a passage 35 to the atmosphere, allowing the piston 32 to move upward and open the contacts until a plug 32a closes a passage 34a in a piston 34. Movement thus stops whilst the arcs are interrupted, and further movement takes place when sufficient air has leaked through an aperture 34b to allow the pistons 32, 34 to move upward together, with the link 44 now held stationary by the plate 43. Movement of the crank 26 results in the movement of the lower end of the lever 45 to the left, allowing the piston 52 to rotate the tube 17 as the link 47 is moved to the right. The plate 43 is reversely rotated to close the valve 39 at the end of the opening stroke. In a closing operation movement of piston 52 and tube 17 result in the operation of valve 40 so as to open the space below the piston 32 to the atmosphere and the operation takes place in one continuous movement. A limit switch assembly 57 may give a positive indication of contact-movement.

Title: Modified polysiloxanes
IPC: C08G77/42
Filed: 1955-05-23
Abstract: Modified polysiloxanes suitable for use in coating compositions comprise polymers having recurring polysiloxane portions connected by divalent bis-(oxyphenyl) alkane readicals, the siloxane units containing 1 to 1.6 silicon-bonded phenyl or phenyl plus methyl groups per silicon atom.  They are prepared by reacting the appropriate polysiloxane containing alkoxy or aryloxy groups with a bis-(hydroxyphenyl) alkane.  Temperatures of from about 180 DEG  to 250 DEG  C. are employed, a solvent may be used and a transesterification catalyst such as a potassium silanolate may also be used.  The polysiloxane starting materials should have from 5 to 50 per cent by weight of alkoxy or aryloxy groups and have a molecular weight of from about 400 to 4,000.  The preparation of such siloxanes is described.  Suitable hydroxyphenyl alkanes are bis-(4- and 2-hydroxyphenyl) methanes, 1,1 - bis - (4 - hydroxyphenyl) ethane and -isobutane, and 2,2-bis-(4-hydroxyphenyl)-propane and -butane. Mixtures thereof may be used.  Part of the hydroxyphenyl alkanes may be replaced by a monohydric phenol or alcohol to limit cross-linking. Hardening ingredients may be added, generally in amount of from 5 to 20 per cent by weight, and these include phenolic, urea and melamine resins and polyhydric alcohols such as glycol, glycerol or pentaerythritol.  These latter alcohols are normally added to the reaction mixture.  A number of examples is given in which xylene is used as a solvent for the reaction mixtures and for the subsequent coating compositions which contain titania as pigment.
