Abstract: 969,426. Variable pitch propellers. BURMEISTER & WAIN'S MASKIN-OG SKIBSBYGGERI A. S. Dec. 28,1962[Dec. 30, 1961], No. 48943/62. Heading B7V. [Also in Division G3] A remote controlled plant comprises a manually actuated control valve 53, Figs. 3 and 5, loaded by a spring 55 which is adjustable by the control lever 66 through a cam 65, rod 62 and lever 58 to provide an outlet pressure at 76 proportional to the position of the lever 66. Rotation of the lever 66 also rotates a valve 67 to connect one of the ports 77, 78 to the space 76 and the other to exhaust through a passage 81 in the valve 67. The control valve 53 closes an inlet port 72 when the pressure in the space 76 equals the force of the spring 55 and opens the space to exhaust port 73 when this pressure exceeds the spring loading. The ports 77, 78 are connected to ports 12, 13, Fig. 1, at opposite sides of piston 14 the movement of which actuates the working member 18, such as a change of pitch mechanism of a ship's propeller. The piston 14 is loaded by a spring 25 located between bearing plates 24, 26 which respectively abut a shoulder formed by a reduced portion 23 of the pistonrod and a nut 27 whereby when the piston moves from its neutral position, as shown, the spring loading is increased for movement in either direction. The cylinder 11 is provided with a groove 110 which tapers in either direction. This allows for release of pressure and ensures a small flow of liquid to provide heat when the piston is stationary. The valve 67 is so shaped to provide no movement of the piston 14 when the lever is first moved to ensure a small sudden pressure which acts on the piston to prevent sticking. The cam is preferably of symmetrical shape to provide equal movements in either direction of the control lever.

Title: Process for producing melamine-urea-formaldehyde concentrates and products obtained thereby
IPC: C08G12/38
Filed: 1962-12-31
Abstract: A stable, aqueous solution of a melamine-urea-formaldehyde reaction product equivalent, for resin forming purposes, to an aqueous solution of formaldehyde, melamine and urea, is obtained by (A) incorporating with an aqueous formaldehyde solution containing 30 to 50% by weight formaldehyde, at a temperature below 80 DEG  C., melamine and urea in amounts such that the resulting mixture contains 2.5 to 5.0 mols. of formaldehyde for each mol. of amino group in the melamine and urea, and 0.5-2.5 mols. of melamine for each mol. of urea, (B) if necessary adjusting the pH of the mixture to within the range 4.5 to 6.0, (C) heating the mixture to 60 DEG  to 80 DEG  C., and then (D) distilling water from the mixture until the liquid residue contains 60 to 90% of all the components other than water. The pH of the aqueous formaldehyde may be adjusted before adding the urea and melamine, so that the pH of the mixture is 4.5 to 6.0. The water may be removed by "flash" evaporation.  The products are stable liquids which may be used to prepare resins with additional urea and melamine. Examples are given.
Patent GB-491476-A (GB)
Abstract: 491,476. Gyroscopic apparatus. SIEMENS APPARATE UND MASCHINEN GES. Nov. 25, 1937, Nos. 32530 and 32531. Convention dates, Nov. 25, 1936 and Dec. 10, 1936. [Class 97 (iii)1 A locking and resetting device, for a directional gyroscope, during the engaging process, first locks the vertical axis and then the horizontal axis and, during the disengaging process releases both axes simultaneously. In the form shown, the vertical gimbal ring 4 carries a disc 8 by means of pins 9, 9<1> which permit it to move only in the direction of the vertical axis. To lock the vertical axis a second disc 11 mounted for axial movement and rotation on the lower vertical bearing 6<1> is raised by a forked lever 17, having pins engaging an annular groove 12 in the disc 11, until a series of circumferential pegs 10a in the disc 11 engage corresponding apertures in the disc 8. The disc 11 carries teeth 14 which normally prevent it from rotating by engagement with a long pinion 36 geared to a worm wheel 34 mounted on the housing 7. Further raising of the lever 17 causes the disc 8 to engage a pin 49 on a lever 45, which is pivoted on the ring 4 at 44 and carries at the other end a roller 46 cooperating with a cam to lock the gyro about the horizontal axis. The lever 17 is raised against the acton of a spring 20 by the engagement with a pin 21 thereon of the cam surface 26 on a slide 22 which is moved by axial movement of a plunger 31 passing through the worm wheel 34. When the plunger 31 is pressed in from its outermost position, the pin 21, originally in the position shown in dotted lines, rides up the cam surface 26 and passes under a spring latch 28 to the uppermost position 24. The gyro is then locked about both axes and a plate 38 on the plunger 31 is in engagement with the worm wheel 34 so that by rotating the plunger the disc 11 may be rotated and the gyro adjusted about the vertical axis. When the plunger is drawn out the pin 21 rides along a part 29 of the latch 28 forming a continuation of the upper cam surface 24 until it reaches an aperture 30 in the latch when it drops instantaneously to the lowermost part 23 of the cam surface causing both axes of the gyro to be released simultaneously. In a modification the slide 22 is moved by a spring which is compressed by the first part of the plunger's movement and then permitted to move the slide by a further movement of the plunger. The plunger may be provided with a safety catch. The, Specifcation describes various other devices for moving the pin 21 in a similar manner. The plunger 31 may be actuated by an electromagnet which may be under remote control or energized automatically at predetermined time intervals. The plunger may also be rotated to effect azimuth adjustment under remote control.
