Abstract: 1,219,289. Automatic control of aircraft. ELLIOTT BROS. (LONDON) Ltd. May 23, 1968 [May 26, 1967J, No. 24763/67. Heading G3R. In an aircraft automatic landing system, signals from a radio receiver responsive to deviation from a glide path, with an integral component added, are combined with airspeed error signals applied through a multiplier stage to produce a resultant signal corresponding to the pitch attitude which the system is to maintain. As shown, signals from a glide slope radio receiver 1 are lagged at 2 and proportioned at 3. Integral and land-pass components derived at 5 and 6 are added at 7 and a signal dependent on airspeed deviation introduced through a multiplier 8. The resultant signal, representing the desired pitch attitude to maintain the aircraft on the glide path, is compared with actual pitch attitude and actual rate of change of pitch attitude signals at 9 so that any error is available at 11 to control the elevators and thus restore the aircraft to the glide path.

Abstract: <PICT:1064687/C6-C7/1> Apparatus for timing apertured printed circuit boards comprises an enclosure at the bottom of which is a solder pot and a rotatable shaft for carrying a board which can be moved between loading, dipping and intermediate positions, in the latter position the shaft is rapidly rotated to fling molten solder from the apertures in the board.  The apparatus comprises a vertically extending metal housing 10 with an exhaust fan 18 at the top and a heated solder pot 20 enclosed in insulating material 22 at the bottom, the solder being covered with a layer of oil.  Two vertically extending rails 27, within the housing carry a slide 25 which is biased to an upper position by chains 28 extending over pulleys 31 and tensioned by springs 32.  The slide can be drawn downwardly by a pair of pneumatic actuators 30 attached to rails 27.  A horizontal axis 40, rotatably mounted on slide 25, carries a transverse rod (46) Fig. 3 (not shown).  At one end of the rod is mounted a counterweight (47) and at the other is attached a rotary air motor (45) having a tubular drive shaft (48) serving as an air exhaust and carrying a jig (50) to which a printed circuit board having Cu circuitry is attached.  The rod (46) is maintained horizontal, extending beyond a loading aperture closed by a sliding door (13) Fig.2 (not shown) by chains 43 each attached to a rail 27 and to sprockets 42 mounted on each end of axle 40. Electric and pneumatic controls maintain the solder at a given temperature and provide an automatic sequence of operations after the board is attached to the jig and the apparatus started. Actuators 30 draw the slide 25 down permitting the rod 40 to rotate into an intermediate vertical position and motor (45) starts to slowly rotate the board.  When the rod reaches the vertical position chains 43 become slack and further movement of the actuators draws the board to a position below the surface 53 of the solder, shown dotted as 50".  After a predetermined interval the board is moved up to the intermediate position and the speed of motor (45) considerably increased to throw off the solder and clear the apertures in the board.  The apertures near the centre of the board not subject to high centrifugal forces are cleared by exhaust air from shaft (48).  Finally the air supply is shut off, the motor stops and springs 32 raise the slide and rotate rod 46 to the horizontal for removal through door (13) of the board.

Title: Process for the manufacture of silicone resins
IPC: C08G77/06
Filed: 1960-07-18
Abstract: In a two-stage process for making a silicone resin from a low molecular weight siloxane resin, the first stage comprises heating a low molecular weight siloxane of the average general formula RnSiO 4-n/2 , in which R is a monovalent saturated or unsaturated hydrocarbon radical and n has an average value of 0,9 to 1,7, at a temperature within the range of 150 DEG  to 325 DEG C. in the presence of 0,001 to 1,0% by weight, based on the weight of the siloxane resin, of a metal of Group Ia, VIa, VIIb or VIII of the Mendel<\>aeeff Periodic System, the metal being present as a metal salt or an organometal salt of a monocarboxylic acid, to produce a high molecular weight siloxane resin, and the second stage comprises curing the resin so produced.  The metal salt may be added either before or during the oxidative condensation reaction.  If desired the stage one resins may be freed of metals by washing with metal-fixing complex formers so that the ultimate resins may be metal-free, but metal salts may be added to the stage one resins to aid in developing the desired stage two resins.  Salts specified are Fe and Cr stearates, Co ethylhexoate, Fe octoate, Cu acetate, Ni propionate and the naphthenates and octoates of Mo, W, Mn, Ni, Pd, Pt, Ag and Au. In a typical example (1) the resin obtained by hydrolysing a mixture of CH3.SiCl3 and (CH3)SiCl2 in aqueous methanol was divided into 5 parts; A served as a control; B contained 0,1% of Fe added as Fe octoate; C contained 0,1% of Cu added as Cu acetate; D contained 0,1% of Co added as Co ethyl hexoate; and E contained 0,1% of Cr added as Cr stearate.  All five were heated at 250 DEG C. for 3 hours, polymerization occurring through condensation of residual -OH and -OCH3 groups but mainly through oxidation of -CH3 groups.  Each resin was then dissolved in butyl acetate and the resulting solutions were applied to steel panels, air dried and aged by heating at 250 DEG C.; coating A crazed after 72 hours at 250 DEG C., whereas the others crazed after much longer periods at 250 DEG C.  Specification 561,136 is referred to.
